    Achieving the Advanced Turbine Systems (ATS) goals of 60% efficiency, single-digit NO{sub x}, and 10% electric power cost reduction imposes competing characteristics on the gas turbine system. Two basic technical issues arise from this. The turbine inlet temperature of the gas turbine must increase to achieve both efficiency and cost goals. However, higher temperatures move in the direction of increased NO{sub x} emission. Improved coatings and materials technologies along with creative combustor design can result in solutions to achieve the ultimate goal. GE`s view of the market, in conjunction with the industrial and utility objectives, requires the development of Advanced Gas Turbine Systems which encompass two potential products: a new aeroderivative combined-cycle system for the industrial market, and a combined-cycle system for the utility sector that is based on an advanced frame machine. The GE Advanced Gas Turbine Development program is focused on two specific products: (1) a 70 MW class industrial gas turbine based on the GE90 core technology utilizing an innovative air cooling methodology; (2) a 200 MW class utility gas turbine based on an advanced Ge heavy-duty machine utilizing advanced cooling and enhancement in component efficiency. Both of these activities required the identification and resolution of technical issues critical to achieving ATS goals. The emphasis for the industrial ATS was placed upon innovative cycle design and low emission combustion. The emphasis for the utility ATS was placed on developing a technology base for advanced turbine cooling, while utilizing demonstrated and planned improvements in low emission combustion. Significant overlap in the development programs will allow common technologies to be applied to both products. GE Power Systems is solely responsible for offering GE products for the industrial and utility markets.

    This work looks into the meanings of nursing from the point of view of the students in an undergraduate nursing degree program. The research took place at the Universidad Nacional de Lanús using semistructured interviews - eleven individual and seven group interviews - carried out between 2008 and 2010. A content analysis was then undertaken and the most relevant meanings in relation to four themes were selected: reasons for studying nursing, what nursing is, nursing as a profession, and working in nursing. Multiple and diverse ways of defining nursing were uncovered. Utilizing some conceptual developments from the sociology of the professions, the meanings were organized into four conceptualizations that represent ways of understanding nursing: as a vocation, as a profession, with a utilitarian perspective and with a community perspective. The conclusions reached indicate the need to broaden the debate regarding the types of nurses that are being trained. PMID:23989623

    This article argues for the existence of persistent conceptual "bugs" in how novices program and understand programs. These bugs are not specific to a given programming language, but appear to be language-independent. Furthermore, such bugs occur for novices from primary school to college age. Three different classes of bugs-parallelism, intentionality, and egocentrism - are identified, and exemplified through student errors. It is suggested that these classes of conceptual bugs are rooted in...

    . Considering the strength and limitations of both methodologies, the question to be answered in this thesis is: How valuable and compatible are the classical analytical methods in today's conceptual design environment? And can these methods complement each other? To answer these questions, this thesis investigates the pros and cons of classical analytical structural analysis methods during the conceptual design stage through the following objectives: Illustrate structural design methodology of these methods within the framework of Aerospace Vehicle Design (AVD) lab's design lifecycle. Demonstrate the effectiveness of moment distribution method through four case studies. This will be done by considering and evaluating the strength and limitation of these methods. In order to objectively quantify the limitation and capabilities of the analytical method at the conceptual design stage, each case study becomes more complex than the one before.

  9. Conceptual Model of Climate Change Impacts at LANL

    Goal 9 of the LANL FY15 Site Sustainability Plan (LANL 2014a) addresses Climate Change Adaptation. As part of Goal 9, the plan reviews many of the individual programs the Laboratory has initiated over the past 20 years to address climate change impacts to LANL (e.g. Wildland Fire Management Plan, Forest Management Plan, etc.). However, at that time, LANL did not yet have a comprehensive approach to climate change adaptation. To fill this gap, the FY15 Work Plan for the LANL Long Term Strategy for Environmental Stewardship and Sustainability (LANL 2015) included a goal of (1) establishing a comprehensive conceptual model of climate change impacts at LANL and (2) establishing specific climate change indices to measure climate change and impacts at Los Alamos. Establishing a conceptual model of climate change impacts will demonstrate that the Laboratory is addressing climate change impacts in a comprehensive manner. This paper fulfills the requirement of goal 1. The establishment of specific indices of climate change at Los Alamos (goal 2), will improve our ability to determine climate change vulnerabilities and assess risk. Future work will include prioritizing risks, evaluating options/technologies/costs, and where appropriate, taking actions. To develop a comprehensive conceptual model of climate change impacts, we selected the framework provided in the National Oceanic and Atmospheric Administration (NOAA) Climate Resilience Toolkit (http://toolkit.climate.gov/).

  10. Conceptual tokamak design at high neutron fluence

    International Nuclear Information System (INIS)

    For the future fusion reactor, it is important to design an experimental device that can be performed testing in-vessel components including tritium breeding modules relevant to the future fusion reactor with high neutron fluence. To realize this requirement, a conceptual tokamak design has been performed in accordance with plasma performance and shape at quasi-steady-state operation. One of the promising scenarios for this purpose is proposed to produce the plasma at the outward shifted radial position with a small minor radius for reasonable plasma parameters. From the analytical results, an appropriate space can be found for neutron shielding so that additional neutron shielding can be installed to protect the tokamak components from any neutron damages under the neutron fluence of 1 MWa m-2. Based on the structural analyses, a two-stage blanket module concept is proposed, i.e. one shielding block with the first wall assembly during high Q operation and two shielding blocks or additional tritium breeding modules during quasi-steady state operation

    The U.S. Department of Energy (DOE) faces many decisions regarding future remedial actions and waste disposal at the Hanford Site in southeast Washington State. To support these decisions, DOE recognized the need for a comprehensive and systematic approach to developing and documenting complete, consistent, and defensible conceptual models of contaminant release and migration. After reviewing existing conceptual model development methodologies that might be applicable to environmental assessments at the Hanford Site, DOE initiated efforts to adapt and implement the Features, Events, and Processes (FEP) methodology developed for use in performance assessments of nuclear waste disposal systems by NIREX. In adapting this methodology for use in the environmental assessments at Hanford, the international list of FEPs, compiled from nuclear waste disposal programs, was evaluated to develop a list of potentially relevant Hanford-specific FEPs. The international nuclear waste programs focus on deep geologic disposal while waste disposal at the Hanford Site involves burial in shallow unconsolidated geologic deposits. Thus, a graphical tool called the Process Relationship Diagram (PRD) was created to assist in identifying the international FEPs and additional factors that are relevant to Hanford, and to illustrate the relationships among these factors. The PRD is similar in form and function to the Master Directed Diagram used by NIREX to provide a visual and systematic structure for the FEP methodology. Adaptation of this approach is showing promise in facilitating the development of conceptual models and selection of relevant factors to be incorporated into environmental uncertainty assessments for the Hanford Site.

  17. Conceptual designs for IR optics at C-Zero

    International Nuclear Information System (INIS)

    Two possible conceptual optical designs for a stand-alone C0 IR insert were presented. Both inserts are optically transparent to the rest of the machine, with no impact on Run IIb Tevatron operating parameters. Both design variations require high-field LHC-like quadrupoles for the final focus triplet. In the first version, with enhanced dipoles creating space for separators in the arcs, collisions can be created at all 3 IP's simultaneously. Stronger dipoles also free more than 26 m of space for the detector. At C0, β* is limited to ge50 cm by βmax in the IR triplets. The second version of the IR has neither new dipoles nor new arc separators. Collider scenarios have either B0 and D0 at collision, or just C0. At C0, β* can be decreased to 40 cm, but the price paid is a substantial reduction in free space available for the detector. This first pass at C0 IR designs has left a number of questions unresolved. A few of these outstanding issues that a second iteration of the IR designs must address are discussed

  1. Conceptual designs of heaters for the westinghouse large coil program

    International Nuclear Information System (INIS)

    The Large Coil Program (LCP) involves the design, fabrication and testing of large superconducting magnets for use in tokamak reactors. The specification requirements of the LCP calls for heating elements to be installed in the test coils. The heaters are required to (a) simulate irradiation heating, (b) test the coil stability and recovery and (c) investigate the limits of stability. The heaters must also be able to drive the superconductor normal to test the coil stability and recovery to the superconducting state without significantly disturbing the helium coolant. This requirement coupled with the large amount of energy needed to drive the Westinghouse forced flow conductor normal and the space limitations in the coil made the heater design difficult. A pulsed inductive heater concept overcomes all the above restrictions. Also discussed is the design procedure for the resistive heaters which will increase the helium temperature in the forced flow conductor sufficiently to drive it normal. 8 refs

    Recent research suggests that school-based kindness education programs may benefit the learning and social-emotional development of youth and may improve school climate and school safety outcomes. However, how and to what extent kindness education programming influences positive outcomes in schools is poorly understood, and such programs are difficult to evaluate in the absence of a conceptual model for studying their effectiveness. In partnership with Kind Campus, a widely adopted school-based kindness education program that uses a bottom-up program framework, a methodology called concept mapping was used to develop a conceptual model for evaluating school-based kindness education programs from the input of 123 middle school students and approximately 150 educators, school professionals, and academic scholars. From the basis of this model, recommendations for processes and outcomes that would be useful to assess in evaluations of kindness education programs are made, and areas where additional instrument development may be necessary are highlighted. The utility of the concept mapping method as an initial step in evaluating other grassroots or non-traditional educational programming is also discussed. PMID:27376750

  4. The Revised WIPP Passive Institutional Controls Program - A Conceptual Plan - 13145

    International Nuclear Information System (INIS)

    The Department of Energy/Carlsbad Field Office (DOE/CBFO) is responsible for managing all activities related to the disposal of TRU and TRU-mixed waste in the geologic repository, 650 m below the land surface, at WIPP, near Carlsbad, New Mexico. The main function of the Passive Institutional Controls (PIC's) program is to inform future generations of the long-lived radioactive wastes buried beneath their feet in the desert. For the first 100 years after cessation of disposal operations, the rooms are closed and the shafts leading underground sealed, WIPP is mandated by law to institute Active Institutional Controls (AIC's) with fences, gates, and armed guards on patrol. At this same time a plan must be in place of how to warn/inform the future, after the AIC's are gone, of the consequences of intrusion into the geologic repository disposal area. A plan was put into place during the 1990's with records management and storage, awareness triggers, permanent marker design concepts and testing schedules. This work included the thoughts of expert panels and individuals. The plan held up under peer review and met the requirements of the U.S. Environmental Protection Agency (EPA). Today the NEA is coordinating a study called the 'Preservation of Records, Knowledge and Memory (RK and M) Across Generations' to provide the international nuclear waste repository community with a guide on how a nuclear record archive programs should be approached and developed. CBFO is cooperating and participating in this project and will take what knowledge is gained and apply that to the WIPP program. At the same time CBFO is well aware that the EPA and others are expecting DOE to move forward with planning for the future WIPP PIC's program; so a plan will be in place in time for WIPP's closure slated for the early 2030's. The DOE/CBFO WIPP PIC's program in place today meets the regulatory criteria, but complete feasibility of implementation is questionable, and may not be in conformance

    Sheri A Lippman

    Full Text Available Community mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted to establish the core components of community mobilization, which are needed to guide HIV prevention programming and evaluation.We aimed to identify the key domains of community mobilization (CM essential to change health outcomes or behaviors, and to determine whether these hypothesized CM domains were relevant to a rural South African setting.We studied social movements and community capacity, empowerment and development literatures, assessing common elements needed to operationalize HIV programs at a community level. After synthesizing these elements into six essential CM domains, we explored the salience of these CM domains qualitatively, through analysis of 10 key informant in-depth-interviews and seven focus groups in three villages in Bushbuckridge.CM DOMAINS INCLUDE: 1 shared concerns, 2 critical consciousness, 3 organizational structures/networks, 4 leadership (individual and/or institutional, 5 collective activities/actions, and 6 social cohesion. Qualitative data indicated that the proposed domains tapped into theoretically consistent constructs comprising aspects of CM processes. Some domains, extracted from largely Western theory, required little adaptation for the South African context; others translated less effortlessly. For example, critical consciousness to collectively question and resolve community challenges functioned as expected. However, organizations/networks, while essential, operated differently than originally hypothesized - not through formal organizations, but through diffuse family networks.To date, few community mobilizing efforts in HIV prevention have clearly defined the meaning and domains of CM prior to intervention design. We distilled six CM domains from the literature; all were pertinent to mobilization in rural South Africa. While some adaptation of

  7. Conceptual design report: below-grade bulk waste disposal facility. Formerly Utilized Sites Remedial Action Program

    International Nuclear Information System (INIS)

    This report presents two conceptual designs for below-grade land disposal facilities in the Northeastern United States for wastes managed under the Formerly Utilized Sites Remedial Action Program (FUSRAP). The wastes are low specific activity radioactive wastes generated by programs of the Manhattan Engineer District/Atomic Energy Commission (MED/AEC). One design presented is for a hypothetical disposal facility for the state of New York and one for the state of New Jersey. Each design is based on the estimated volume of FUSRAP waste in each state. Since no specific sites have been identified for the disposal facilities, the geologic, hydrologic, topographic, and meteorologic conditions chosen for the conceptual design are only representative of conditions in New York and New Jersey. The principal difference in the two sites is the assumed soil permeability which requires an engineered clay liner surrounding the waste for the New York facility, but not for the New Jersey facility. The conceptual designs are intended to be conservative and were developed to be compatible with proposed 10 CFR 61 and proposed 40 CFR 192. The designs are developed in sufficient detail to verify the feasibility of the design concepts and to provide a basis for developing capital cost estimates for below-grade land disposal facilities

    2016-01-01

    Congenital hearing loss is the most frequent birth defect. The American Academy of Pediatrics and the Joint Committee on Infant Hearing established quality of care process indicators for Universal Newborn Hearing Screening starting from 1999. In a previous systematic review of Universal Newborn Hearing Screening studies we highlighted substantial variability in program design and in reported performance data. In order to overcome these heterogeneous findings we think it is necessary to optimize the implementation of Universal Newborn Hearing Screening programs with an appropriate application of the planning, executing, and monitoring, verifications and reporting phases. For this reason we propose a conceptual framework that logically integrates these three phases and, consequently, a tool (a check-list) for their rationalization and standardization.Our paper intends to stimulate debate on how to ameliorate the routine application of high quality Universal Newborn Hearing Screening programs. The conceptual framework is proposed to optimize, rationalise and standardise their implementation. The checklist is intended to allow an inter-program comparison by removing heterogeneity in processes description and assessment. PMID:26872853

    2009-10-30

    This Conceptual Design Report (CDR) describes the design of FACET. It will be updated to stay current with the developing design of the facility. This CDR begins as the baseline conceptual design and will evolve into an 'as-built' manual for the completed facility. The Executive Summary, Chapter 1, gives an introduction to the FACET project and describes the salient features of its design. Chapter 2 gives an overview of FACET. It describes the general parameters of the machine and the basic approaches to implementation. The FACET project does not include the implementation of specific scientific experiments either for plasma wake-field acceleration for other applications. Nonetheless, enough work has been done to define potential experiments to assure that the facility can meet the requirements of the experimental community. Chapter 3, Scientific Case, describes the planned plasma wakefield and other experiments. Chapter 4, Technical Description of FACET, describes the parameters and design of all technical systems of FACET. FACET uses the first two thirds of the existing SLAC linac to accelerate the beam to about 20GeV, and compress it with the aid of two chicanes, located in Sector 10 and Sector 20. The Sector 20 area will include a focusing system, the generic experimental area and the beam dump. Chapter 5, Management of Scientific Program, describes the management of the scientific program at FACET. Chapter 6, Environment, Safety and Health and Quality Assurance, describes the existing programs at SLAC and their application to the FACET project. It includes a preliminary analysis of safety hazards and the planned mitigation. Chapter 7, Work Breakdown Structure, describes the structure used for developing the cost estimates, which will also be used to manage the project. The chapter defines the scope of work of each element down to level 3.

A concept for economic evaluation should be based on the efficacy of physical activity, the standard methods of economic evaluation and the aims of public health. Previous publications have examined only parts of these components and have not developed a comprehensive conceptual framework; it is the objective of this article to develop such a framework. The derived method should aid decision makers and staff members of intervention programs in reviewing and conducting an economic evaluation. A literature search of articles was done using six electronic databases. Referenced works for standard methods and more comprehensive approaches for evaluation of preventive programs were studied. The newly developed conceptual framework for economic evaluation includes: (1) the type of physical activity program; (2) features of a selected study population; (3) the outcome dimension comprising exercise efficacy, reach, recruitment, response rate, maintenance, compliance and adverse health effects plus the social impact; and (4) the cost dimension consisting of program development costs, program implementation costs including the implementation, recruitment, program, participants' time costs and savings resulting from the health effects of the intervention. Cost-effectiveness also depends on the methodology, such as the chosen perspective, data collection, valuation methods and discounting. If an intervention is not considered cost-effective, it is necessary to check each dimension to find possible failures in order to learn for future interventions. A more detailed economic evaluation is of utmost importance for improved comparability and transferability. PMID:21773728

    Although sibling relationships can be considered as one of the most durable and intensive relationships, not much research in developmental psychology and family research has been done on this issue. The strong focus on parents, more specifically on mothers, stood in the way of adequate conceptualization and understanding of the function and contribution of siblings to individual development and family interaction. In this contribution a conceptualization of sibling relationships is presented. Siblings as objects of aggressive and sexual feelings as well as the function of siblings in the family system, for example, as parentification and negative identity is emphasized. In addition, the different qualities of sibling relationships, for example, envy, rivalry, similarity, and difference, are emphasized. The function of siblings as love objects is stressed, and the role of siblings as support as well as teaching object is illustrated. Finally, it is emphasized that, similar to relationships between parents and child, the quality of sibling relationships changed over time and leads, for example, to a detachment between sibling relationships during adolescence.

  13. Nova program at LLNL

    International Nuclear Information System (INIS)

    At LLNL, successful experimental work is being performed with the Nova laser facility, a solid state laser system using neodymium-doped glass laser technology. Nova is the primary U.S. facility devoted to the study of the indirect drive approach to inertial fusion. In this concept, energy from a laboratory driver is converted to radiation that is used to implode and heat the fusion fuel in an inertial fusion capsule. Nova's principial objective is to demonstrate that laser-driven hohlraums (chambers that trap electromagnetic radiation) can meet the conditions of driver/target coupling efficiency, driver irradiation symmetry, driver pulse-shaping, target preheat, and hydrodynamic stability required by hot spot ignition and by fuel compression in order to realize net fusion gain (fusion energy released/driver energy delivered). Major results within the Nova Program fall within the areas of laser performance, target diagnostics, and implosion experiments. (author) 2 figs

  14. Teaching strategies and conceptual change in a professional development program for science teachers of K--8

    Shen, Ji

    This case study investigates two consecutive science courses for teachers of K-8 in a professional development program at Washington University. It aims (1) to trace the processes of the teachers' conceptual change; (2) to analyze the teaching strategies by course instructors; and (3) to try to establish possible links between the two. To achieve this goal, I build a modeling theory to account for the observations. The main body of the study consists of four sub-cases. The first two cases instantiate the elements of the modeling theory. The opening case of balance shows that learning tools and task structures shape the learning outcome, and discusses cycles of modeling. The case also delineates the strategy that the instructors employed---moving from concrete experience to abstract explanation. The second case of buoyancy demonstrates that the modeling theory is able to explain the origins and forming mechanism of the alternative conceptions held by the teachers. It also shows that the teaching strategies of using alternative conceptions, applying analogies and following a logical sequence helped the teachers build new models. The last two cases demonstrate the ways of improving the competence of modelers. The third case of physical models emphasizes the metacognition of the learner who builds models. It illustrates that teachers' level of self-awareness in learning is increased when the models are physical. It shows that the creativity of modeling is rooted in agency, curiosity, communicability, and confidence, and that a chain of transformation among models is the key of systematizing and forming knowledge. The last case of frames of reference tries to answer the question "what is the justification of models if there are alternatives?" The teachers employed different forms of justification which relied heavily on common sense, authority, relativism, and pragmatism, all of which are not rational. While discussing both the positive and negative traits of these

  15. Conceptual plan: Two-Phase Flow Laboratory Program for the Waste Isolation Pilot Plant

    International Nuclear Information System (INIS)

    The Salado Two-Phase Flow Laboratory Program was established to address concerns regarding two-phase flow properties and to provide WIPP-specific, geologically consistent experimental data to develop more appropriate correlations for Salado rock to replace those currently used in Performance Assessment models. Researchers in Sandia's Fluid Flow and Transport Department originally identified and emphasized the need for laboratory measurements of Salado threshold pressure and relative permeability. The program expanded to include the measurement of capillary pressure, rock compressibility, porosity, and intrinsic permeability and the assessment of core damage. Sensitivity analyses identified the anhydrite interbed layers as the most likely path for the dissipation of waste-generated gas from waste-storage rooms because of their relatively high permeability. Due to this the program will initially focus on the anhydrite interbed material. The program may expand to include similar rock and flow measurements on other WIPP materials including impure halite, pure halite, and backfill and seal materials. This conceptual plan presents the scope, objectives, and historical documentation of the development of the Salado Two-Phase Flow Program through January 1993. Potential laboratory techniques for assessing core damage and measuring porosity, rock compressibility, capillary and threshold pressure, permeability as a function of stress, and relative permeability are discussed. Details of actual test designs, test procedures, and data analysis are not included in this report, but will be included in the Salado Two-Phase Flow Laboratory Program Test Plan pending the results of experimental and other scoping activities in FY93

    International Nuclear Information System (INIS)

    This report documents the TFE Conceptual Design, which provided the design guidance for the TFE Verification program. The primary goals of this design effort were: (1) establish the conceptual design of an in-core thermionic reactor for a 2 Mw(e) space nuclear power system with a 7-year operating lifetime; (2) demonstrate scalability of the above concept over the output power range of 500 kW(e) to 5 MW(e); and (3) define the TFE which is the basis for the 2 MW (e) reactor design. This TFE specification provided the basis for the test program. These primary goals were achieved. The technical approach taking in the conceptual design effort is discussed in Section 2, and the results are discussed in Section 3. The remainder of this introduction draws a perspective on the role that this conceptual design task played in the TFE Verification Program

    The Radiation Protection Center of the Iraqi Ministry of Environment is developing a groundwater monitoring program (GMP) for the Al-Tuwaitha Nuclear Research Center located near Baghdad, Iraq. The Al-Tuwaitha Nuclear Research Center was established in about 1960 and is currently being cleaned-up and decommissioned by Iraq's Ministry of Science and Technology. This Groundwater Monitoring Program Plan (GMPP) and Conceptual Site Model (CSM) support the Radiation Protection Center by providing:A CSM describing the hydrogeologic regime and contaminant issues,recommendations for future groundwater characterization activities, anddescriptions of the organizational elements of a groundwater monitoring program. The Conceptual Site Model identifies a number of potential sources of groundwater contamination at Al-Tuwaitha. The model also identifies two water-bearing zones (a shallow groundwater zone and a regional aquifer). The depth to the shallow groundwater zone varies from approximately 7 to 10 meters (m) across the facility. The shallow groundwater zone is composed of a layer of silty sand and fine sand that does not extend laterally across the entire facility. An approximately 4-m thick layer of clay underlies the shallow groundwater zone. The depth to the regional aquifer varies from approximately 14 to 17 m across the facility. The regional aquifer is composed of interfingering layers of silty sand, fine-grained sand, and medium-grained sand. Based on the limited analyses described in this report, there is no severe contamination of the groundwater at Al-Tuwaitha with radioactive constituents. However, significant data gaps exist and this plan recommends the installation of additional groundwater monitoring wells and conducting additional types of radiological and chemical analyses.

    Youth participation in program and community decision making is framed by scholars as an issue of social justice, a platform for positive youth development and effective citizenry, and a strategy for nation building. Recent literature reviews have consistently identified youth-adult partnership (Y-AP) as an effective type of youth participation across highly diverse contexts. These same reviews, however, note that indicators of Y-AP have not been conceptualized and validated for measurement purposes. The present study addresses this limitation by developing a brief measure of Y-AP that is explicitly grounded in current theory, research, and community practice. The measure was administered to youth in the United States, Malaysia, and Portugal (N = 610). Validation was assessed through factor analysis and tests of factorial, discriminant, and concurrent validity. Results confirmed the two predicted dimensions of the Y-AP measure: youth voice in decision making and supportive adult relationships. These two dimensions were also found to be distinct from other measures of program quality: safety and engagement. As predicted, they also significantly correlated with measures of agency and empowerment. It is concluded that the measure has the potential to support community efforts to maximize the quality of youth programs. PMID:25216734

    Happiness at the workplace refers to how satisfied people are with their work and lives. The idea of happiness is related to individual’s subjective well-being. Happiness at the workplace is crucial for improving productivity in any organization. Happy people are productive people while those people who are unhappy may not pay full attention to any task. Some scholars believe that organizations which are able to maintain long-term happiness at the workplace could probably increase and sustain...

  3. Conceptual Model for Assessing the Minimum Size Area for an Area-Wide Integrated Pest Management Program

    International Nuclear Information System (INIS)

    A conceptual model was developed based on the two basic spatial elements of area-wide integrated pest management (AW-IPM), a core area and a buffer zone, to determine the minimum size of the protected area for the program to be technically feasible and economically justifiable. The model consisted of a biological part (insect dispersal) and an economic part. The biological part used random walks and diffusion equations to describe insect dispersal and to determine the minimum width of the buffer zone required to protect the core area from immigration of pests from outside. In the economic part, the size of the core area was calculated to determine the point at which the revenues from the core area equal the control costs. This model will need to be calibrated and validated for each species and geographic location. Tsetse flies and the Mediterranean fruit fly are used as case studies to illustrate the model. (author)

    1992-06-15

    The Solenoidal Tracker At RHIC (STAR) will search for signatures of quark-gluon plasma (QGP) formation and investigate the behavior of strongly interacting matter at high energy density. The emphasis win be the correlation of many observables on an event-by-event basis. In the absence of definitive signatures for the QGP, it is imperative that such correlations be used to identify special events and possible signatures. This requires a flexible detection system that can simultaneously measure many experimental observables. The physics goals dictate the design of star and it`s experiment. To meet the design criteria, tracking, momentum analysis, and particle identification of most of the charged particles at midrapidity are necessary. The tracking must operate in conditions at higher than the expected maximum charged particle multiplicities for central Au + Au collisions. Particle identification of pions/kaons for p < 0.7 GeV/c and kaons/protons for p < 1 GeV/c, as well as measurement of decay particles and reconstruction of secondary vertices will be possible. A two-track resolution of 2 cm at 2 m radial distance from, the interaction is expected. Momentum resolution of {Delta}p/p {approximately} 0.02 at p = 0.1 GeV/c is required to accomplish the physics, and,{Delta}p/p of several percent at p = 10 GeV/c is sufficient to accurately measure the rapidly failing spectra at high Pt and particles from mini-jets and jets.

    The fate and transport of 129I in the environment and potential remediation technologies are currently being studied as part of environmental remediation activities at the Hanford Site. A conceptual model describing the nature and extent of subsurface contamination, factors that control plume behavior, and factors relevant to potential remediation processes is needed to support environmental remedy decisions. Because 129I is an uncommon contaminant, relevant remediation experience and scientific literature are limited. Thus, the conceptual model also needs to both describe known contaminant and biogeochemical process information and to identify aspects about which additional information needed to effectively support remedy decisions. this document summarizes the conceptual model of iodine behavior relevant to iodine in the subsurface environment at the Hanford site.

    Indigenous development of helium liquefiers is regarded as a high priority area at BARC, Mumbai. A precooled Collin's cycle based helium liquefier conceived to work between pressure limits of 0.105 and 1.3 MPa (a) and with mass flow rate of 62 g/s is reported in the present paper. The system is designed to achieve a liquefaction rate of about 57 l/hr with the lowest temperature as 4.86 K. Effect of different heat exchanger effectiveness and turbine efficiency values on the liquefier performance has also been theoretically studied and reported here. Design and development methodology of the liquefier cold box has been dealt with. The present paper also describes the current state of installation and commissioning activities of the above described helium liquefier at BARC, Mumbai. First trial runs are expected soon after the completion of the transferline circuit from the liquefier cold box to the liquid helium receiver vessel. (author)

    The sport of volleyball creates considerable dynamic trunk stability demands. Back injury occurs all too frequently in volleyball, particularly among female athletes. The purpose of this clinical commentary is to review functional anatomy, muscle coactivation strategies, assessment of trunk muscle performance, and the characteristics of effective exercises for the trunk or core. From this information, a conceptual progressive 3-phase volleyball-specific training program is presented to improve dynamic trunk stability and to potentially reduce the incidence of back injury among volleyball athletes. Phase 1 addresses low-velocity motor control, kinesthetic awareness, and endurance, with the clinician providing cues to teach achievement of biomechanically neutral spine alignment. Phase 2 focuses on progressively higher velocity dynamic multiplanar endurance, coordination, and strength-power challenges integrating upper and lower extremity movements, while maintaining neutral spine alignment. Phase 3 integrates volleyball-specific skill simulations by breaking down composite movement patterns into their component parts, with differing dynamic trunk stability requirements, while maintaining neutral spine alignment. Prospective research is needed to validate the efficacy of this program. PMID:18978452

    Test beam and irradiation facilities are the key enabling infrastructures for research in high energy physics (HEP) and astro-particles. In the last 11 years the Beam-Test Facility (BTF) of the DA{\\Phi}NE accelerator complex in the Frascati laboratory has gained an important role in the European infrastructures devoted to the development and testing of particle detectors. At the same time the BTF operation has been largely shadowed, in terms of resources, by the running of the DA{\\Phi}NE electron-positron collider. The present proposal is aimed at improving the present performance of the facility from two different points of view: extending the range of application for the LINAC beam extracted to the BTF lines, in particular in the (in some sense opposite) directions of hosting fundamental physics and providing electron irradiation also for industrial users; extending the life of the LINAC beyond or independently from its use as injector of the DA{\\Phi}NE collider, as it is also a key element of the electron/...

    International Nuclear Information System (INIS)

    A feasibility study of a spallation neutron source based on a rapid-cycling synchrotron which delivers a proton beam of 2 GeV in energy and 0.5 mA time-averaged current at a 30 Hz repetition rate is presented. The lattice consists of 90-degree phase advance FODO cells with dispersion-free straight sections, and has a three-fold symmetry. The ring magnet system will be energized by 20 Hz and 60 Hz resonant circuits to decrease the dB/dt during the acceleration cycle. This lowers the peak acceleration voltage requirement to 130 kV. The single turn extraction system will be used to extract the beam alternatively to two target stations. The first station will operate at 10 Hz for research using long wavelength neutrons, and the second station will use the remaining pulses, collectively, providing 36 neutron beams. The 400 MeV negative-hydrogen-ion injector linac consists of an ion source, rf quadrupole, matching section, 100 MeV drift-tube linac, and a 300 MeV coupled-cavity linac

    International Nuclear Information System (INIS)

    The Department of Energy (DOE), Office of New Production Reactors (NPRs), has initiated contracts with three architect-engineer/reactor vendors for the conceptual design phase (CDP) for new production reactors. This is the first major step of a procurement process that will proceed through final design, construction, testing, and operation of the facility. In preparation for the CDP for the NPRs, DOE developed a set of requirements that would serve as the basic technical reference throughout the entire life of the program-from the CDP to decommissioning. The objective was to establish requirements that, when met, will result in NPR capacity that will provide NPRs with design margins of sufficient magnitude to (1) provide the production capacity to supply goal quantities of tritium reliably and on a timely schedule; (2) provide a level of safety assurance that meets or exceeds that offered to the public by modern commercial nuclear power plants; (3) meet or exceed the applicable federal, state, and local regulations for safety and environmental requirements; (4) assure the availability of reactor, fuel, target, and processing technology for full-scale production on an urgent schedule with low schedule risk; and (5) meet the overall goal in the most cost-effective manner. The objectives of the CDP for the HWR [heavy-water reactor]-NPR are to provide comprehensively defined technical, cost, and schedule baselines for proceeding into preliminary design and to ensure that the technical and management competency of the CDP contractor team for conducting the preliminary design is demonstrated

    The authors are studying conceptual designs of selected nondestructive assay (NDA) instruments for the near-real-time accounting system at the rokkasho Reprocessing Plant (RRP) of Japan Nuclear Fuel Limited (JNFL). The JNFL RRP is a large-scale commercial reprocessing facility for spent fuel from boiling-water and pressurized-water reactors. The facility comprises two major components: the main process area to separate and produce purified plutonium nitrate and uranyl nitrate from irradiated reactor spent fuels, and the co-denitration process area to combine and convert the plutonium nitrate and uranyl nitrate into mixed oxide (MOX). The selected NDA instruments for conceptual design studies are the MOX-product canister counter, holdup measurement systems for calcination and reduction furnaces and for blenders in the co-denitration process, the isotope dilution gamma-ray spectrometer for the spent fuel dissolver solution, and unattended verification systems. For more effective and practical safeguards and material control and accounting at RRP, the authors are also studying the conceptual design for the UO{sub 3} large-barrel counter. This paper discusses the state-of-the-art NDA conceptual design and research and development activities for the above instruments.

  2. Development of a conceptual framework to guide a program of research exploring nurse-to-nurse communication.

    Research in nursing informatics has been described as problem based rather than theory guided. Furthermore, few examples exist in the literature where the process of theory development is described. This article describes a process used to develop a conceptual framework that supports a theory-driven program of research in nursing informatics. The conceptual framework combines Symbolic Interaction Theory and Information Theory. Constructs of Symbolic Interaction Theory (mind, self, and society) and Information Theory (entropy, negentropy, redundancy, probability, and noise) were then organized according to Gerbner's Communication Model. Theory derivation was the method used for organizing abstract constructs and reducing them to a measurable level. Theory derivation was supplemented with initial research findings. The measurable or middle-range constructs were then organized in a meaningful manner for conceptual framework development. The use of theory derivation to develop a conceptual framework to support theory-driven nursing informatics research will be discussed. The framework entitled "Effective Nurse-to-Nurse Communication" that guides a program of research will then be presented. PMID:22411412

  3. Plant performance monitoring program at Krsko NPP

    International Nuclear Information System (INIS)

    A high level of nuclear safety and plant reliability results from the complex interaction of a good design, operational safety and human performance. This is the reason for establishing a set of operational plant safety performance indicators, to enable monitoring of both plant performance and progress. Performance indicators are also used for setting challenging targets and goals for improvement, to gain additional perspective on performance relative to other plants and to provide an indication of a potential need to adjust priorities and resources to achieve improved overall plant performance. A specific indicator trend over a certain period can provide an early warning to plant management to evaluate the causes behind the observed changes. In addition to monitoring the changes and trends, it is also necessary to compare the indicators with identified targets and goals to evaluate performance strengths and weaknesses. Plant Performance Monitoring Program at Krsko NPP defines and ensures consistent collection, processing, analysis and use of predefined relevant plant operational data, providing a quantitative indication of nuclear power plant performance. When the program was developed, the conceptual framework described in IAEA TECDOC-1141 Operational Safety Performance Indicators for Nuclear Power Plants was used as its basis in order to secure that a reasonable set of quantitative indications of operational safety performance would be established. Safe, conservative, cautious and reliable operation of the Krsko NPP is a common goal for all plant personnel. It is provided by continuous assurance of both health and safety of the public and employees according to the plant policy stated in program MD-1 Notranje usmeritve in cilji NEK, which is the top plant program. Establishing a program of monitoring and assessing operational plant safety performance indicators represents effective safety culture of plant personnel.(author)

    The strategy of the ATS program is to develop a new baseline for industrial gas turbine systems for the 21st century, meeting the buying criteria of industrial gas turbine end users, and having growth potential. These criteria guided the Solar ATS Team in selecting the system definition described in this Topical Report. The key to selecting the ATS system definition was meeting or exceeding each technical goal without negatively impacting other commercial goals. Among the most crucial goals are the buying criteria of the industrial gas turbine market. Solar started by preliminarily considering several cycles with the potential to meet ATS program goals. These candidates were initially narrowed based on a qualitative assessment of several factors such as the potential for meeting program goals and for future growth; the probability of successful demonstration within the program`s schedule and expected level of funding; and the appropriateness of the cycle in light of end users` buying criteria. A first level Quality Function Deployment (QFD) analysis then translated customer needs into functional requirements, and ensured favorable interaction between concept features. Based on this analysis, Solar selected a recuperated cycle as the best approach to fulfilling both D.O.E. and Solar marketing goals. This report details the design and analysis of the selected engine concept, and explains how advanced features of system components achieve program goals. Estimates of cost, performance, emissions and RAMD (reliability, availability, maintainability, durability) are also documented in this report.

  5. A Comprehensive and Systematic Approach to Developing and Documenting Conceptual Models of Contaminant Release and Migration at the Hanford Site

    International Nuclear Information System (INIS)

    The U. S. Department of Energy?s Richland Operations Office has initiated efforts to adapt and implement the Features, Events, and Processes (FEPs) methodology (used in scenario development for nuclear waste disposal programs) to the environmental management and remediation problems facing the Hanford Site. These efforts have shown that modification of the FEPs methodology to incorporate the use of Process Relationship Diagrams (PRD) is effective in facilitating the development of conceptual models and selection of potentially relevant factors to be incorporated into a specific performance assessment. In developing this methodology for Hanford, a master PRD was created to provide an organization structure for identifying the potentially relevant factors (i.e. FEPs) and for illustrating the relationships between these factors. This organizational framework was developed to match the organization of current Hanford site-wide performance assessment activities and to facilitate screening of the FEPs relevant to the problems (and conceptual models) that need to be addressed at the site. However, the link between Hanford specific FEPs and the international list of FEPs was maintained to demonstrate completeness and perhaps to expand the usefulness of the international list for other environmental programs

  6. Heavy water program: Technical requirements, conceptual design phase process and reactor characteristics

    International Nuclear Information System (INIS)

    In preparation for the Conceptual Design Phase (CDP) for the New Production Reactors (NPRs), the Department developed a set of requirements that would serve as the basic technical reference throughout the entire life of the program - from the CDP to decommissioning. The objective was to establish requirements which when met, will result in new production reactor capacity that will provide NPRs with design margins of sufficient magnitude: that will meet or exceed the level of safety assurance achieved by recent commercial reactors; that will provide a high degree of production assurance; that will achieve a level of environmental performance which will assure that requirements established in the NEPA process are met; and that will provide a high degree of confidence that the reactor will be constructed to meet urgent schedule needs. The NPR Requirements Document sets forth the management, technical, and implementing requirements for the CDP Process. Specifically, the implementing requirements define those contractor products (e.g., records, plans, analyses, studies, designs) to be developed and delivered during the CDP. The objectives of the CDP for the HWR-NPR are to provide comprehensively defined technical, cost and schedule baselines for proceeding into preliminary design and to ensure that the technical and management competency of the CDP contractor team for conducting the preliminary design is demonstrated. The mission to produce special nuclear materials by neutron induced transmutation of target materials has a major impact on the design of the reactor core and the reactor operating systems. This leads to the use of aluminum technology and, as a consequence, low temperature operation

  7. BRAHMS: Conceptual design report. Forward angle and midrapidity hadron spectrometers at RHIC

    International Nuclear Information System (INIS)

    The Broad RAnge Hadron Magnetic Spectrometers experiment (BRAHMS) is designed to measure charged hadrons over a wide range of rapidity and transverse momentum for all available beams and energies. This conceptual design report describes the BRAHMS detector and how it will be installed and operated at RHIC. Chapter 2 presents an overview of the physics program to be achieved with the BRAHMS Experiment. This is followed in Chapter 3 by an overview of the detector systems, a description which is close to earlier designs but changed to reflect updates. The magnet design is reviewed in Chapter 4. Chapter 5 describes the requirements that the BRAHMS Experiment sets for the intersection region. The arguments for the proposed positioning of the two magnet arms are presented. The needed support buildings and their possible placements are discussed. Chapter 6 examines the requirements on the elements of the forward arm, and demonstrates the feasibility of the proposed combination of magnets and tracking detectors. Most of the detectors are small TPC's, and several features of a prototoye TPC and the testing thereof are describes. The particle identification in BRAHMS is achieved by time-of-flight techniques and Cerenkov counters. This is describes in Chapter 7. The global detectors, i.e., the beam-beam counters and the multiplicity detector, are described next in Chapter 8. The concept for a centrality detector based on silicon strips is presented; a backup scheme employs an array of proportional gas counters. Considerations on data aquisition and triggers, as given next in Chapter 9, are fairly conventional and shoud not pose any major problems for development. The cost estimate for the experiment is given last; the total budget for BRAHMS is within the original goal

  9. Do we need stimulation programs as a part of nursing care for patients in "persistent vegetative state"? A conceptual analysis.

    Tolle, Patrizia; Reimer, Marlene

    2003-12-01

    The rehabilitative care of persons suffering long-lasting effects of brain injury is a significant challenge for nurses as they are the health professionals who usually spend the most time with them. Historically in Germany, the term "apallic syndrome" has been commonly used for what Plum and Posner (1980) termed the persistent vegetative state. When persons are diagnosed as being in a persistent vegetative state, that is awake but not aware, for more than six months, they seldom receive active therapy except what nurses or families may provide. Stimulation programs have been advocated for these persons, but there is still no reliable evidence as to their effectiveness, and the conceptual basis of the two main types of programs has been poorly understood. The multisensory stimulation approach, such as the Coma Recovery Program or Coma Arousal Therapy, is based on behaviourism with the belief that intensive stimulation provided to all senses will enhance synaptic reinnervation and stimulate the reticular activating system to increase brain tone. In contrast, the sensory regulation approach is based on information processing and mediation of reaction to sensory information with emphasis on enhancing selective attention by regulating the environment rather than providing high degrees of stimulation. What both approaches have in common is the belief that the person in a persistent vegetative state may, at some level, be able to perceive and begin to process information and that external stimulation may enhance that process. Nurses interacting with persons in persistent vegetative state are encouraged to think about how they can regulate sensory input to enhance meaning and facilitate information processing for these persons.

  10. Public health and health promotion capacity at national and regional level: a review of conceptual frameworks

    2014-04-01

    Full Text Available The concept of capacity building for public health has gained much attention during the last decade. National as well as international organizations increasingly focus their efforts on capacity building to improve performance in the health sector. During the past two decades, a variety of conceptual frameworks have been developed which describe relevant dimensions for public health capacity. Notably, these frameworks differ in design and conceptualization. This paper therefore reviews the existing conceptual frameworks and integrates them into one framework, which contains the most relevant dimensions for public health capacity at the country or regional level. A comprehensive literature search was performed to identify frameworks addressing public health capacity building at the national or regional level. We content-analysed these frameworks to identify the core dimensions of public health capacity. The dimensions were subsequently synthesized into a set of thematic areas to construct a conceptual framework which describes the most relevant dimensions for capacities at the national or regional level. The systematic review resulted in the identification of seven core domains for public health capacity: resources, organizational structures, workforce, partnerships, leadership and governance, knowledge development and country specific context. Accordingly, these dimensions were used to construct a framework, which describes these core domains more in detail. Our research shows that although there is no generally agreed upon model of public health capacity, a number of key domains for public health and health promotion capacity are consistently recurring in existing frameworks, regardless of their geographical location or thematic area. As only little work on the core concepts of public health capacities has yet taken place, this study adds value to the discourse by identifying these consistencies across existing frameworks and by synthesising

  11. Study of a conceptual nuclear energy center at Green River, Utah. Final summary report

    International Nuclear Information System (INIS)

    This document summarizes a conceptual study on the feasibility and practicality of developing a nuclear energy center (NEC) at a representative Western site. The site selected for this conceptual study, an area of about 50 square miles, is located 15 miles south of Green River, Utah. The conceptual NEC would consist of nine nuclear electric generating units, arranged on the site in three clusters of three reactors each (triads), separated by about 2 1/2 miles. Of the total electric output of 11,250 MWe that the NEC could produce, about 82% is assumed to be transmitted out of Utah to Colorado, New Mexico, Arizona, Nevada, and California. The technical engineering issues studied included geology and seismology, plant design, low-level radioactive waste disposal, transmission, and construction schedules and costs. Socioeconomic issues included were demographics, land use, community service needs, and fiscal impacts. Environmental considerations included terrestrial and aquatic ecology, visual impact, and secondary population impacts. Radiological issues were concerned with the safety and risks of an NEC and an on-site low-level waste facility. Institutional issues included methods of ownership, taxation, implications of energy export, and water allocation. The basic finding was that an NEC would be technically feasible, but a number of socioeconomic and institutional issues would require resolution before a Western regional NEC could be considered a viable power plant siting option

  12. Modular programming method at JAERI

    International Nuclear Information System (INIS)

    In this report the histories, concepts and a method for the construction and maintenance of nuclear code systems of Japan Atomic Energy Research Institute (JAERI) are presented. The method is mainly consisted of novel computer features. The development process of the features and experiences with them which required many man-months and efforts of scientists and engineers of JAERI and a computer manufacturer are also described. One of the features is a file handling program named datapool. The program is being used in code systems which are under development at JAERI. The others are computer features such as dynamic linking, reentrant coding of Fortran programs, interactive programming facility, document editor, quick system output viewer and editor, flexible man-machine interactive Fortran executor, and selective use of time-sharing or batch oriented computer in an interactive porgramming environment. In 1980 JAERI has replaced its two old computer systems by three FACOM M-200 computer systems and they have such features as mentioned above. Since 1981 most code systems, or even big single codes can be changed to modular code systems even if the developers or users of the systems will not recognize the fact that they are using modular code systems. The purpose of this report is to describe our methodology of modular programming from aspects of computer features and some of their applications to nuclear codes to get sympathetic understanding of it from persons of organizations who are concerned with the effective use of computers, especially, in nuclear research fields.

    A key component in risk assessment of contaminated sites is in the formulation of a conceptual site model (CSM). A CSM is a simplified representation of reality and forms the basis for the mathematical modeling of contaminant fate and transport at the site. The CSM should therefore identify the...... most important site-specific features and processes that may affect the contaminant transport behavior at the site. However, the development of a CSM will always be associated with uncertainties due to limited data and lack of understanding of the site conditions. CSM uncertainty is often found to be a...

    A brief summary of the experimental program at CEBAF to study electro-magnetic transitions of nucleon resonances is given. The need for complete data sets, including measurements of polarization observables is stressed. It is emphasized that insight into fundamental properties of hadronic matter can be obtained by studying the Q2 evolution of resonance transition amplitudes and their comparison with microscopic models of baryons

  16. Conceptual engineered cover design for the solar evaporation ponds at the Rocky Flats Plant

    International Nuclear Information System (INIS)

    The Rocky Flats Plant, located outside of Denver, Colorado, operated several lined Solar Evaporation Ponds (SEP) from 1953 until 1986 for the disposal of liquid radioactive and hazardous waste. The US Department of Energy (DOE) has signed an Interagency Agreement with the Colorado Department of Health and the US Environmental Protection Agency, agreeing to close the SEP through an Interim Measures/Interim Remedial Action accelerated program. The DOE is considered an alternative: to consolidate contaminated liner materials, debris, and soil media under an engineered cover. The regulatory agencies may approve this alternative if DOE demonstrates that it would protect human health and the environment for a 1,000-yr period as required by the Colorado hazardous landfill siting regulations. The DOE utilized research results from the Hanford and Los Alamos sites to design an engineered cover for the SEP that would fulfill the regulatory requirements. This paper presents the conceptual design of the engineered cover

    2014-03-01

    The effective cost management during the conceptual design phase of a product is essential to develop a product with minimum cost and desired quality. The integration of the methodologies of quality function deployment (QFD), value engineering (VE) and target costing (TC) could be applied to the continuous improvement of any product during product development. To optimize customer satisfaction and total cost of a product, a mathematical model is established in this paper. This model integrates QFD, VE and TC under multi-objective optimization frame work. A case study on domestic refrigerator is presented to show the performance of the proposed model. Goal programming is adopted to attain the goals of maximum customer satisfaction and minimum cost of the product.

    2015-01-01

    The 160 GeV polarised muon beam available at CERN, with positive or negative charge, makes COMPASS a unique place for GPD studies. The first GPD related COMPASS results come from exclusive vector meson production on transversely polarised protons and deuterons. The data were taken in 2003-2010 with large solid-state polarised targets, although without detection of recoil particles. Results on various transverse target spin dependent azimuthal asymmetries are presented and their relations to GPDs are discussed. The dedicated COMPASS GPD program started in 2012 with commissioning of a new long liquid hydrogen target and new detectors such as the large recoil proton detector and the large-angle electromagnetic calorimeter. It was followed by a short pilot 'DVCS run'. The performance of the setup and first results on DVCS and exclusive $\\pi ^0$ channels have been demonstrated. The full data taking for the GPD program approved within COMPASS-II proposal is planned for 2016 and 2017.

  19. Precursor incident program at EDF

    International Nuclear Information System (INIS)

    The precursor program was started by EDF in 1994, after an investigation of the US NRC's Accident Sequence Precursor Program. Since then, reported operational events identified as Safety Outstanding Events have been analyzed whenever possible using probabilistic methods based on PSAs. Analysis provides an estimate of the remaining protection against core damage at the time the incident occurred. Measuring the incidents' severity enables to detect incidents important regarding safety. Moreover, the most efficient feedback actions can be derived from the main accident sequences identified through the analysis. Therefore, incident probabilistic analysis provides a way to assess priorities in terms of treatment and resource allocation, and so, to implement countermeasures preventing further occurrence and development of the most significant incidents. As some incidents cannot be analyzed using this method, probabilistic analysis can only be one among the methods used to assess the nuclear power plants' safety level. Nevertheless, it provides an interesting complement to classical methods of deterministic studies. (author)

  20. Evolution of the conceptual model of unsaturated zone hydrology at yucca mountain, nevada

    International Nuclear Information System (INIS)

    Yucca Mountain is an arid site proposed for consideration as the United States' first underground high-level radioactive waste repository. Low rainfall (approximately 170 mm/yr) and a thick unsaturated zone (500-1000 m) are important physical attributes of the site because the quantity of water likely to reach the waste and the paths and rates of movement of the water to the saturated zone under future climates would be major factors in controlling the concentrations and times of arrival of radionuclides at the surrounding accessible environment. The framework for understanding the hydrologic processes that occur at this site and that control how quickly water will penetrate through the unsaturated zone to the water table has evolved during the past 15 yr. Early conceptual models assumed that very small volumes of water infiltrated into the bedrock (0.5-4.5 mm/yr, or 2-3 percent of rainfall), that much of the infiltrated water flowed laterally within the upper nonwelded units because o f capillary barrier effects, and that the remaining water flowed down faults with a small amount flowing through the matrix of the lower welded, fractured rocks. It was believed that the matrix had to be saturated for fractures to show. However, accumulating evidence indicated that infiltration rates were higher than initially estimated, such as infiltration modeling based on neutron borehole data, bomb-pulse isotopes deep in the mountain, perched water analyses and thermal analyses. Mechanisms supporting lateral diversion did not apply at these higher fluxes, and the flux calculated in the lower welded unit exceeded the conductivity of the matrix, implying vertical flow of water into the high permeability fractures of the potential repository host rock, and disequilibrium between matrix and fracture water potentials. The development of numerical modeling methods and parameter values evolved concurrently with the conceptual model in order to account for the observed field data

    2014-01-01

    In this paper we summarize recent measurements of exclusive reactions at COMPASS, which are a part of the GPD program. New results on the transverse target spin asymmetries for exclusive 0 production are presented. Some of these asymmetries are sensitive to the GPDs E , which are related to the orbital angular momentum of quarks. Other asymmetries are sensitive to the chiral-odd, transverse GPDs H T . Planned measurements of Deeply Virtual Compton Scattering, which are a part of the approved COMPASS-II proposal, are also discussed. The main aim of these measurements is access to the GPDs H , which are related to the 3-dimensional nucleon tomography.

  4. Status of the Astrid core at the end of the pre-conceptual design phase 1

    International Nuclear Information System (INIS)

    Within the framework of the ASTRID project, core design studies are being conducted by the CEA with support from AREVA and EDF. The pre-conceptual design studies are being conducted in accordance with the GEN IV reactor objectives, particularly in terms of improving safety. This involves limiting the consequences of 1) a hypothetical control rod withdrawal accident (by minimizing the core reactivity loss during the irradiation cycle), and 2) an hypothetical loss-of-flow accident (by reducing the sodium void worth). Two types of cores are being studied for the ASTRID project. The first is based on a 'large pin/small spacing wire' concept derived from the SFR V2b, while the other is based on an innovative CFV design. A distinctive feature of the CFV core is its negative sodium void worth. In 2011, the evaluation of a preliminary version (v1) of this CFV core for ASTRID underlined its potential capacity to improve the prevention of severe accidents. An improved version of the ASTRID CFV core (v2) was proposed in 2012 to comply with all the control rod withdrawal criteria, while increasing safety margins for all unprotected-loss-of-flow (ULOF) transients and improving the general design. This paper describes the CFV v2 design options and reports on the progress of the studies at the end of pre-conceptual design phase 1 concerning: - Core performance, - Intrinsic behavior during unprotected transients, - Simulation of severe accident scenarios, - Qualification requirements. The paper also specifies the open options for the materials, sub-assemblies, absorbers, and core monitoring that will continue to be studied during the conceptual design phase. (authors)

  5. Advanced turbine systems program -- Conceptual design and product development. Final report

    1996-07-26

    This Final Technical Report presents the accomplishments on Phase 2 of the Advanced Turbine Systems (ATS). The ATS is an advanced, natural gas fired gas turbine system that will represent a major advance on currently available industrial gas turbines in the size range of 1--20 MW. This report covers a market-driven development. The Market Survey reported in Section 5 identified the customer`s performance needs. This market survey used analyses performed by Solar turbine Incorporated backed up by the analyses done by two consultants, Research Decision Consultants (RDC) and Onsite Energy Corporation (Onsite). This back-up was important because it is the belief of all parties that growth of the ATS will depend both on continued participation in Solar`s traditional oil and gas market but to a major extent on a new market. This new market is distributed electrical power generation. Difficult decisions have had to be made to meet the different demands of the two markets. Available resources, reasonable development schedules, avoidance of schedule or technology failures, probable acceptance by the marketplace, plus product cost, performance and environmental friendliness are a few of the complex factors influencing the selection of the Gas Fired Advanced Turbine System described in Section 3. Section 4 entitled ``Conversion to Coal`` was a task which addresses the possibility of a future interruption to an economic supply of natural gas. System definition and analysis is covered in Section 6. Two major objectives were met by this work. The first was identification of those critical technologies that can support overall attainment of the program goals. Separate technology or component programs were begun to identify and parameterize these technologies and are described in Section 7. The second objective was to prepare parametric analyses to assess performance sensitivity to operating variables and to select design approaches to meet the overall program goals.

  6. 1994 conceptual model of the carbon tetrachloride contamination in the 200 West Area at the Hanford Site

    International Nuclear Information System (INIS)

    Between 1955 and 1973, a total of 363,000 to 580,000 L (577,000 to kg) of liquid carbon tetrachloride, in mixtures with other organic and aqueous, actinide-bearing fluids, were discharged to the soil column at three disposal facilities -- the 216-Z-9 Trench, the 216-Z-lA TiTe Field, and the 216-Z-18 Crib -- in the 200 West Area at the Hanford Site. In the mid-1980's, dissolved carbon tetrachloride was found in the uppermost aquifer beneath the disposal facilities, and in late 1990, the US Environmental Protection Agency and the Washington State Department of Ecology requested that the US Department of Energy proceed with planning and implementation of an expedited response action (ERA) to minimize additional carbon tetrachloride contamination of the groundwater. In February 1992, soil vapor extraction was initiated to remove carbon tetrachloride from the unsaturated zone beneath these disposal facilities. By May 1994, a total of 10,560 L (16,790 kg) of carbon tetrachloride had been removed, amounting to an estimated 2% of the discharged inventory. In the spring of 1991, the Volatile Organic Compounds -- Arid Integrated Demonstration (VOC-Arid ID) program selected the carbon tetrachloride-contaminated site for demonstration and deployment of new technologies for evaluation and cleanup of volatile organic compounds and associated contaminants in soils and groundwater at arid sites. Site investigations conducted in support of both the ERA and the VOC-Arid ID have been integrated because of their shared objective to refine the conceptual model of the site and to promote efficiency. Site characterization data collected in fiscal year 1993 have supported and led to refinement of the conceptual model of the carbon tetrachloride site

  7. Methodology of life cycle cost with risk expenditure for offshore process at conceptual design stage

    International Nuclear Information System (INIS)

    This study proposed a new LCC (life cycle cost) methodology with the risk expenditure taken into account for comparative evaluation of offshore process options at their conceptual design stage. The risk expenditure consisted of the failure risk expenditure and the accident risk expenditure. The former accounted for the production loss and the maintenance expense due to equipment failures while the latter reflected the asset damage and the fatality worth caused by disastrous accidents such as fire and explosion. It was demonstrated that the new LCC methodology was capable of playing the role of a process selection basis in choosing the best of the liquefaction process options including the power generation systems for a floating LNG (Liquefied natural gas) production facility. Without the risk expenditure, a simple economic comparison apparently favored the mixed refrigerant cycle which had the better efficiency. The new methodology with the risk expenditure, however, indicated that the nitrogen expansion cycle driven by steam turbines should be the optimum choice, mainly due to its better availability and safety. -- Highlights: → The study presented the methodology of the LCC with the risk expenditure for the conceptual design of offshore processes. → The proposed methodology demonstrated the applicability of the liquefaction unit with the power generation system of LNG FPSO. → Without the risk expenditure, a simple economic comparison apparently favored the mixed refrigerant cycle which had the better efficiency. → The new methodology indicated that the nitrogen expansion cycle driven by steam turbines is the optimum choice due to its better availability and safety.

  8. A conceptual framework for formulating a focused and cost-effective fire protection program based on analyses of risk and the dynamics of fire effects

    International Nuclear Information System (INIS)

    This paper proposes a conceptual framework for developing a fire protection program at nuclear power plants based on probabilistic risk analysis (PRA) of fire hazards, and modeling the dynamics of fire effects. The process for categorizing nuclear power plant fire areas based on risk is described, followed by a discussion of fire safety design methods that can be used for different areas of the plant, depending on the degree of threat to plant safety from the fire hazard. This alternative framework has the potential to make programs more cost-effective, and comprehensive, since it will allow a more systematic and broader examination of fire risk, and provide a means to distinguish between high and low risk fire contributors.

    Education on the subject of groundwater is crucial for sustainability. Nevertheless, international studies with students across different age groups have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Drawing from international research, a multimedia learning program Zwischen Regenwolke und Wasserhahn (between the rain cloud and the tap) was developed, which incorporates specific insights from the fields of conceptual change research, multimedia research, and the model of educational reconstruction. The effectiveness of the learning program was ascertained by means of two studies with Austrian seventh grade pupils as well as teacher-training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge of groundwater were determined in a pre- and post-test. The pupils and students greatly benefitted from working through the learning software independently. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results indicate that theory-guided multimedia learning programs can play an important role in the transfer of research results to classroom settings, especially in science education.

    This paper provides an overview of the construction of a conceptual framework regarding ICT-Assistive Technology (ICT-AT) competence development, designed to gain awareness of the elements involved and to facilitate the understanding and exchange among stakeholders of the ENTELIS (European Network for Technology Enhanced Learning in an Inclusive Society) project. The framework was designed based on the basic principles of Activity Theory, which however have been adapted and adjusted to the project's objectives. Hence, it includes a map of actors and other parameters functioning in a person surrounding "ecosystem", and it allows us to understand and map roles, expectations, barriers, as well as to devise solutions to tackle digital divide. Taking as a starting and central point the person and his/her wish to self-determination and fulfilment (quality of life) and the related needs, it provides a map of how the various concepts and variables interact within the theoretical and methodological perspective of the collection, description and assessment of experiences in ICT-AT education and competences development of persons with disabilities (PwD) of all ages. The conceptual framework represents two interacting learning activity systems: (a) the internal system of the end-user, which includes the end-user and his/her needs, the setting where learning takes place and the other actors involved, and (b) the external system, which embraces the internal system but also wider issues of policy and practice and experiences and 'actors' that contribute to the development and use of ICT and ICT-AT skills in all areas of life. The elements of these systems and their interaction provide the basis for analysing experiences and advancing knowledge relevant for bridging the digital divide. PMID:26294545

    The Yucca Mountain Performance Confirmation program consists of tests, monitoring activities, experiments, and analyses to evaluate the adequacy of assumptions, data, and analyses that form the basis of the conceptual and numerical models of flow and transport associated with a proposed radioactive waste repository at Yucca Mountain, Nevada. The Performance Confirmation program uses an eight-stage risk-informed, performance-based approach. Selection of the Performance Confirmation activities (a parameter and a test method) for inclusion in the Performance Confirmation program was done using a risk-informed performance-based decision analysis. The result of this analysis and review was a Performance Confirmation base portfolio that consists of 20 activities. The 20 Performance Confirmation activities include geologic, hydrologic, and construction/engineering testing. Several of the activities were initiated during site characterization and are ongoing. Others activities will commence during construction and/or post emplacement and will continue until repository closure.

    Designers need practical tools to aid decision making at the conceptual stage of building design. The aim of this paper is to investigate, using the early design model, the comparative impact of varying building parameters on the cost of non-domestic buildings. Cost comprises of the cost of operational energy, capital, and embodied energy (EE). Integrated assessment of cost as a function of the following parameters has been carried out: overall heat loss coefficient, obstruction, depth of room, lighting level, installed illuminance, room temperature, rate of infiltration, efficiency of heating plant, incidental heat gain, glazing ratio, cost of windows, and coefficient of performance of cooler. For the specific non-domestic building considered, inclusion of EE in the analysis does not significantly influence design but may have an impact on material choices. (author)

    This is a final technical report for a project of the U.S Nuclear Regulatory Commission (sponsored contract NRC-04-090-51) with the University of Arizona. The contract was an optional extension that was initiated on July 21, 1994 and that expired on May 31, 1995. The project manager was Thomas J. Nicholson, Office of Nuclear Regulatory Research. The objectives of this contract were to examine hypotheses and conceptual models concerning unsaturated flow and transport through fractured rock, and to design and execute confirmatory field and laboratory experiments to test these hypotheses and conceptual models at the Apache Leap Research Site near Superior, Arizona. The results discussed here are products of specific tasks that address a broad spectrum of issues related to flow and transport through fractures. Each chapter in this final report summarizes research related to a specific set of objectives and can be read and interpreted as a separate entity. The tasks include detection and characterization of historical rapid fluid flow through fractured rock and the relationship to perched water systems using environmental isotopic tracers of 3H and 14C, fluid- and rock-derived 2343U/238U measurements, and geophysical data. The water balance in a small watershed at the ALRS demonstrates the methods of acounting for ET, and estimating the quantity of water available for infiltration through fracture networks. Grain density measurements were made for core-sized samples using a newly designed gas pycnometer. The distribution and magnitude of air permeability measurements have been measured in a three-dimensional setting; the subsequent geostatistical analysis is presented. Electronic versions of the data presented here are available from authors; more detailed discussions and analyses are available in technical publications referenced herein, or soon to appear in the professional literature

  3. Competing conceptualizations of decent work at the intersection of health, social and economic discourses.

    2015-05-01

    According to the International Labour Organization (ILO), decent work is critical to economic and social progress and well-being. The ILO's Decent Work Agenda outlines four directions (creating jobs, guaranteeing rights at work, extending social protection, promoting social dialogue) (ILO, 2015). While the Agenda's existence may imply consensus about its meaning, we contend that several conceptualizations of decent work exist in the global policy arena. Different institutional perspectives must be negotiated, and political, economic, social and health considerations balanced in its pursuit. This paper reports findings from a critical discourse analysis of 10 policy texts that aimed to reveal different health, economic, and social claims about decent work and how these are shaped by the work policy agendas of the ILO, World Health Organization, and World Bank. Themes emerging from the discourse analysis include the: challenges and realities of promoting "one" agenda; complex intersection between decent work, health and health equity concepts; emphasis on economic and pro-market interests versus the social dimensions of work; and, relative emphasis on individual versus collective responsibility for decent work. To our knowledge, this is a first attempt to contrast different conceptualizations of decent work involving these institutions. Our findings suggest that decent work is a contested notion, and that more than one "agenda" is operating in the face of vested institutional interests. Broader discourses are contributing to a reframing of decent work in economic, social and/or health terms and these are impacting which dimensions of work are taken up in policy texts over others. Results show how the language of economics acts as a disciplinary and regulatory power and its role as a normalizing discourse. We call for research that deepens understanding of how a social, economic and health phenomenon like work is discursively re-interpreted through different global

  5. Conceptual analysis of the fuel management strategy for the RA-3 research reactor at 10 MW

    International Nuclear Information System (INIS)

    The Argentine Research Reactor RA-3 was designed to produce radioisotopes and it operates with LEU (U3O8) fuel since 1990. Its initial power was 5 MW and it has recently been upgraded to 10 MW. The National Atomic Energy Commission (CNEA) is both its owner and operator. At the beginning of this year, the Nuclear Regulatory Authority extended its operation license to an authorised power of 10 MW after a series of modifications and tests carried out by the installation during 2002 and 2003. As a consequence of this power increase, the installation introduced some non-systematic modifications in its fuel management strategy with the purpose of preserving the operation period in 20 days approximately. The main change was to load 2 fuel elements per cycle in some cycles (instead of 1 as it used to be at 5 MW). The purpose of this work is to perform a conceptual analysis of possible fuel management strategies for the RA-3 reactor, that could provide quantitative elements for a safety assessment, as well as to evaluate the fuel management flexibility at 10 MW in compliance with standards in force. It is concluded that operation at 10 MW with a 2 FE/cycle strategy leads to a significant excess reactivity at the beginning of cycle, but still in compliance with the margins established by the standards of application.

    Pohang Accelerator Laboratory (PAL) is developing a Multipole Wiggler (MPW14) to utilize high-energy (approx 30 keV) synchrotron radiation at Pohang Light Source (PLS). The MPW14 is a hybrid type device to achieve maximum peak flux density and wide beam fan that can serve two beamlines. PLS MPW14-features period of 14 cm, minimum gap of 14 mm, 20 full field periods, maximum flux density of 2.06 T, 3036 mm total magnetic structure length. The peak flux density is very high compared to the other wigglers of similar pole gap and the period. The high peak flux density was possible using advanced new magnetic material and optimized magnetic geometry. The MPW14 will be used in hard X-ray region of 10-30 keV at 2.5 GeV electron energy. The total photon power is 6.19 kW and the peak power density is 5.27 kW/mrad sup 2 at 2.5 GeV, 150 mA. To withstand the big magnetic loads with minimum deflections, C-type support structure is designed with detailed FEM structural analysis. In this article, all the conceptual design e...

  8. Building of a conceptual model at UE25-c hole complex

    International Nuclear Information System (INIS)

    US Geological Survey and Lawrence Berkeley Laboratory are attempting to construct a conceptual model of the UE25-c hole complex. An interdisciplinary approach is discussed where all the available data are integrated. Site geology, borehole geophysics and hydraulic test results at UE25-c hole complex suggest that groundwater flow may be controlled by fractures and faults. Significant clusters of fractures in the C-holes are perpendicular to bedding and may be cooling cracks or may be tectonically induced. Unresolved evidence indicates that a fault may intersect the C-holes. For these reasons a porous medium approximation of the rock in the saturated zone at the scale of a well test may be inappropriate. Instead, an Equivalent Discontinuum Model is proposed to model the UE25-c complex hydrology. EDM does not reproduce every geometrical detail of the real system, but instead, attempts to reproduce the observed behavior of the fracture system while preserving the inherent discontinuous nature of the system. 6 refs., 7 figs

  9. A conceptual design of the RF system for the NSP high intensity proton accelerator at JAERI

    International Nuclear Information System (INIS)

    JAERI has been proposing the Neutron Science Project which aims at exploring the fields of basic science and nuclear technology using a high power spallation neutron source. The neutron source will be driven by a high intensity linear accelerator with an energy of 1.5 GeV and an average beam current of 5.33 mA and beam power of 8 MW. The RF system for the accelerator consists of a high-energy accelerator part and a low energy accelerator part. The maximum RF power requirements at the high and low energy accelerator parts are 25 MW and 8.3 MW, respectively. In this report, we describe the conceptual design of the RF system. In the low energy accelerator part, we estimated the requirement for the high-power amplifier tube and made the basis design for RF components. In the high energy accelerator part, we studied the effect of tuning errors, Lorentz forces and microphonics in the superconducting cavity. We calculated the klystron efficiency and supply power in the arrangement of where one klystron distributes the RF power to four cavities. We also considered an IOT RF system. Finally, we describe the electrical capacity and quantity of cooling water in the RF system. (author)

  10. Dielectric and Radiative Properties of Sea Foam at Microwave Frequencies: Conceptual Understanding of Foam Emissivity

    Peter W. Gaiser

    2012-04-01

    Full Text Available Foam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative processes in foam. We present a physical description of foam dielectric properties obtained from the foam dielectric constant including foam skin depth; foam impedance; wavelength variations in foam thickness, roughness of foam layer interfaces with air and seawater; and foam scattering parameters such as size parameter, and refraction index. Using these, we analyze the scattering, absorption, reflection and transmission in foam and gain insights into why volume scattering in foam is weak; why the main absorption losses are confined to the wet portion of the foam; how the foam impedance matching provides the transmission of electromagnetic radiation in foam and maximizes the absorption; and what is the potential for surface scattering at the foam layers boundaries. We put all these elements together and offer a conceptual understanding for the high, black-body-like emissivity of foam floating on the sea surface. We also consider possible scattering regimes in foam.

  11. Conceptual operations report for a repository at the Yucca Mountain site

    International Nuclear Information System (INIS)

    This study develops conceptual operations scenarios for underground mining development and waste emplacement at the prospective nuclear waste repository in tuff at the Nevada Test Site. Methods and operations required for mining, transportation and material handling, maintenance and shop practice, construction, large-diameter hole drilling, and waste emplacement and storage are presented for both the horizontal and vertical emplacement methods. These methods were developed from all current information collected by the Nevada Nuclear Waste Storage Investigations project and operations data from underground mines. Underground mining and waste emplacement operations will require the following. The underground operations of the horizontal and vertical emplacement methods require approximately 188 and 548 employees, respectively. The total power consumption for the underground operations, excluding mine lighting and instrumentation, is 1815 kVA for the horizontal emplacement method (assuming a shaft-headframe material handling system is employed) and 2945 kVA for the vertical emplacement method (assuming a 20% grade ramp material handling system is employed). The amount of water required for the mining operations in both emplacement methods is approximately 38 gal/ft of drift. This does not include the water required for dust control and pilot hole drilling. Thirty-six mobile units are required for the horizontal emplacement method and 73 mobile units are required for the vertical emplacement method. 4 references, 12 tables

    Drawing rocks at primary school: a tool for emerging misconceptions and promoting conceptual change Luca Benciolini Dipartimento di Fisica, Chimica e Ambiente, Università di Udine (Italy) and Giuseppe Muscio Museo Friulano di Storia Naturale (Udine, Italy) In order to investigate spontaneous ideas of children about rock samples, the Museo Friulano di Storia Naturale in collaboration with the Università di Udine submitted six classrooms of fifth and fourth grade-students to a specific test. One hundred thirty-three students without a specific background in Earth Sciences were asked to give a) a written description of a rock sample; b) a drawing of the sample; c) a written short story about the sample. The selected thirty-five samples in the opinion of the researchers contain 255 geologically relevant self-evident characters such as fossils, clastic textures, planar discontinuities and so on. Childs spontaneously described 209 geological characters. Forty-seven fifth-grade students (group A) have been previously followed specific training in multisensory description of objects and observed the 90% of the geologically relevant characters. Group B (forty-three fifth-grade) and group C (forty-three fourth-grade) on the contrary, without any previous instructions discovered the 77%. In order to follow childs building their knowledge through experience we found that the main problem was the lack of consistency between written and drawing description. Heterogeneities as evident as a magmatic contact have been correctly represented by the drawing but it has not been worth of any attention in the written description. On the contrary, written description may sometimes contain careful description of the clastic sedimentary process but these criteria are applied for example to a travertine, without any relations with observed characters. Descriptions and drawing of rock outcrops performed by university students demonstrate the persistence of this attitude. Thus, groups B and

  16. Study of a conceptual nuclear energy center at Green River, Utah: licensing considerations

    International Nuclear Information System (INIS)

    This report examines the laws governing the location of a 9-unit nuclear energy center (NEC) near Green River, Utah. The time frame being considered for development of the conceptual NEC is from 1995 to 2013. Accordingly, the report is forced to speculate about some aspects of the plant, its site and its construction. Most of the report examines existing legal requirements for constructing an NEC. Where pertinent, changes in the law are discussed that would affect an NEC that is to be licensed in one or two decades. In general, no insurmountable legal problems exist that would prevent an NEC from being licensed at the Green River location. Several legal requirements pose significant concerns and would have to be faced before an NEC could be built. Among the major legal constraints are radiation protection, regulatory approval of financing, access to water, and local zoning restrictions. Two other constraints that involve legal matters are the wisdom of standardization of the units and the responsibility of the NEC builder to correct socio-economic impacts on the local area

  17. Is there a temperature? conceptual challenges at high energy, acceleration and complexity

    CERN Document Server

    2011-01-01

    Physical bodies can be hot or cold, moving or standing,simple or complex. In all such cases one assumes that their respective temperature is a well defined attribute.  What if, however, the ordinary measurement of temperature by direct body contact is not possible?  One conjectures its value, and yes, its very existence, by reasoning based on basic principles of thermodynamics. Is There a Temperature?  Conceptual Challenges at High Energy, Acceleration and Complexity, by Dr. Tamás Sándor Bíró, begins by asking the questions “Do we understand and can we explain in a unified framework the temperature of distant radiation sources, including event horizons, and that of the quark matter produced in high energy accelerator experiments? Or the astounding fluctuations on financial markets?” The book reviews the concept of temperature from its beginnings through the evolution of classical thermodynamics and atomic statistical physics through contemporary models of high energy particle matter.  Based on the...

  18. A Bayesian belief network approach for assessing uncertainty in conceptual site models at contaminated sites

    A key component in risk assessment of contaminated sites is in the formulation of a conceptual site model (CSM). A CSM is a simplified representation of reality and forms the basis for the mathematical modeling of contaminant fate and transport at the site. The CSM should therefore identify the most important site-specific features and processes that may affect the contaminant transport behavior at the site. However, the development of a CSM will always be associated with uncertainties due to limited data and lack of understanding of the site conditions. CSM uncertainty is often found to be a major source of model error and it should therefore be accounted for when evaluating uncertainties in risk assessments. We present a Bayesian belief network (BBN) approach for constructing CSMs and assessing their uncertainty at contaminated sites. BBNs are graphical probabilistic models that are effective for integrating quantitative and qualitative information, and thus can strengthen decisions when empirical data are lacking. The proposed BBN approach facilitates a systematic construction of multiple CSMs, and then determines the belief in each CSM using a variety of data types and/or expert opinion at different knowledge levels. The developed BBNs combine data from desktop studies and initial site investigations with expert opinion to assess which of the CSMs are more likely to reflect the actual site conditions. The method is demonstrated on a Danish field site, contaminated with chlorinated ethenes. Four different CSMs are developed by combining two contaminant source zone interpretations (presence or absence of a separate phase contamination) and two geological interpretations (fractured or unfractured clay till). The beliefs in each of the CSMs are assessed sequentially based on data from three investigation stages (a screening investigation, a more detailed investigation, and an expert consultation) to demonstrate that the belief can be updated as more information

  19. A conceptual approach to the estimation of societal willingness-to-pay for nuclear safety programs

    International Nuclear Information System (INIS)

    The design, refurbishment and future decommissioning of nuclear reactors are crucially concerned with reducing the risk of radiation exposure that can result in adverse health effects and potential loss of life. To address this concern, large financial investments have been made to ensure safety of operating nuclear power plants worldwide. The efficacy of the expenditures incurred to provide safety must be judged against the safety benefit to be gained from such investments. We have developed an approach that provides a defendable basis for making that judgement. If the costs of risk reduction are disproportionate to the safety benefits derived, then the expenditures are not optimal; in essence the societal resources are being diverted away from other critical areas such as health care, education and social services that also enhance the quality of life. Thus, the allocation of society's resources devoted to nuclear safety must be continually appraised in light of competing needs, because there is a limit on the resources that any society can devote to extend life. The purpose of the paper is to present a simple and methodical approach to assessing the benefits of nuclear safety programs and regulations. The paper presents the Life-Quality Index (LQI) as a tool for the assessment of risk reduction initiatives that would support the public interest and enhance both safety and the quality of life. The LQI is formulated as a utility function consistent with the principles of rational decision analysis. The LQI is applied to quantify the societal willingness-to-pay (SWTP) for safety measures enacted to reduce of the risk of potential exposures to ionising radiation. The proposed approach provides essential support to help improve the cost-benefit analysis of engineering safety programs and safety regulations.

  20. Joint Assessment of Parameter and Conceptual Model Uncertainty at the Hanford Site 300 Area

    Assessment of conceptual model and parameter uncertainties is important for science-based decision making, long-term stewardship and monitoring network design. We use the recently developed Maximum Likelihood Bayesian Model Averaging (MLBMA) method to assess jointly the uncertainty associated with alternative flow and transport models, and their parameters, at the 300 Area of the DOE Hanford Site in Washington. Eight groundwater flow and transport model alternatives are considered representing various levels of model complexity, e.g., the degree to which they resolve temporal variations in river stage and spatial variations in hydraulic and transport parameters. The eight models are implemented using MODFLOW and MT3DMS in conjunction with the statistical parameter estimation package PEST and its sensitivity routine SENSAN within the framework of GMS (Groundwater Modeling System). Each of the eight flow and transport models is calibrated jointly against site measurements of hydraulic head and concentration. Parameters found to be insensitive to these measurements and measurements found to have negligible effect on model parameters are excluded from the calibration. The relative plausibility of each calibrated model is expressed in terms of a posterior model probability computed on the basis of Kashyap's information criterion KIC. Models having relatively small posterior probabilities are discarded and those with relatively large posterior probabilities are retained to obtain MLBMA predictions of flow and transport at the site. This is done by (a) using the parameter estimates and their covariance matrices to generate numerous Monte Carlo realizations of model parameters; (b) generating corresponding realizations of predicted heads, concentrations and fluxes; (c) computing the mean and variance of these quantities over all realizations; and (d) averaging the latter over all models using their posterior probabilities as weights. We conclude by comparing the predictive

    In this work, we present the conceptual design of the backscattering time-of-flight spectrometer MIRACLES approved for construction at the long-pulse European Spallation Source (ESS). MIRACLES's unparalleled combination of variable resolution, high flux, extended energy, and momentum transfer (0.2-6 Å(-1)) ranges will open new avenues for neutron backscattering spectroscopy. Its remarkable flexibility can be attributed to 3 key elements: the long-pulse time structure and low repetition rate of the ESS neutron source, the chopper cascade that tailors the moderator pulse in the primary part of the spectrometer, and the bent Si(111) analyzer crystals arranged in a near-backscattering geometry in the secondary part of the spectrometer. Analytical calculations combined with instrument Monte-Carlo simulations show that the instrument will provide a variable elastic energy resolution, δ(ħ ω), between 2 and 32 μeV, when using a wavelength of λ ≈ 6.267 Å (Si(111)-reflection), with an energy transfer range, ħ ω, centered at the elastic line from -600 to +600 μeV. In addition, when selecting λ ≈ 2.08 Å (i.e., the Si(333)-reflection), δ(ħ ω) can be relaxed to 300 μeV and ħ ω from about 10 meV in energy gain to ca -40 meV in energy loss. Finally, the dynamic wavelength range of MIRACLES, approximately 1.8 Å, can be shifted within the interval of 2-20 Å to allow the measurement of low-energy inelastic excitations. PMID:27587171

  7. Checkout program at the BNFP

    International Nuclear Information System (INIS)

    Inspections and initial flushes revealed a small number of minor problems related to construction. Volume measurement accuracies of better than 0.1% were demonstrated for accountability vessels. Air lift design proved to be the major process problem area. While fluid movement capabilities of the air lifts were satisfactory, entrainment (air into the streams, liquid into vent lines) and flow measurement uncertainty caused several operational problems. A number of air lift modifications were made during the tests and further changes are planned based on experimental work conducted at AGNS. The design rate of 5 MTU/day was demonstrated; however, air lift problems limited the average rate to only 3.9 MTU/day. All of the process equipment performed at or above required capacities with no major problems. The electrocell did not produce as much uranium (IV) as predicted, primarily due to solvent degradation interference; however, it was sufficient to meet flowsheet plutonium reduction requirements

  8. Detailed heat load calculations at the beginning, middle, and end of cycle for the conceptual design of the Advanced Neutron Source Reactor

    International Nuclear Information System (INIS)

    The Advanced Neutron Source (ANS) is a world-class research reactor and experimental center for neutron research, presently being designed at the Oak Ridge National Laboratory (ORNL). The reactor consists of a 330-MW(f) highly enriched uranium core, which is cooled, moderated, and reflected with heavy water. When completed, it will be the preeminent ultrahigh neutron flux reactor in the world, with facilities for research programs in biology, materials science, chemistry, fundamental and nuclear physics, and analytical chemistry. Irradiation facilities are provided for a variety of isotope production capabilities, as well as materials irradiation. The ANS reactor design, at the time of this report, has completed the conceptual design phase and entered the advanced conceptual design phase. This report is part of an effort to fully document the analysis methods and results for the conceptual design. It details the methods used to perform heat load calculations on the ANS reactor design, describes the model used, and gives the resulting heat loads in all components of the reactor, in both a differential (by segment) and integral (by component) fashion. These heat load data are provided at three times within the ANS fuel cycle - at beginning (0 days), middle (8.5 days), and end (17 days) of cycle. The remainder of the report is dedicated to this description. In Chapter 2, some necessary background on the reactor design is provided. Chapters 3 and 4 give details of the depletion methods used and revisions to previous MCNP models.

    The purpose of this letter is to forward the Prometheus preconceptual Instrumentation and Control (I&C) system architecture (Enclosure (1)) to NR for information as part of the Prometheus closeout work. The preconceptual 1&C system architecture was considered a key planning document for development of the I&C system for Project Prometheus. This architecture was intended to set the technical approach for the entire I&C system. It defines interfaces to other spacecraft systems, defines hardware blocks for future development, and provides a basis for accurate cost and schedule estimates. Since the system requirements are not known at this time, it was anticipated that the architecture would evolve as the design of the reactor module was matured.

    The New Mexico Environment Department (NMED) requires a Corrective Measures Evaluation to evaluate potential remedial alternatives for contaminants of concern (COCs) in groundwater at Sandia National Laboratories New Mexico (SNUNM) Technical Area (TA)-V. These COCs consist of trichloroethene, tetrachloroethene, and nitrate. This document presents the current conceptual model of groundwater flow and transport at TA-V that will provide the basis for a technically defensible evaluation. Characterization is defined by nine requirement areas that were identified in the NMED Compliance Order on Consent. These characterization requirement areas consist of geohydrologic characteristics that control the subsurface distribution and transport of contaminants. This conceptual model document summarizes the regional geohydrologic setting of SNUNM TA-V. The document also presents a summary of site-specific geohydrologic data and integrates these data into the current conceptual model of flow and contaminant transport. This summary includes characterization of the local geologic framework; characterization of hydrologic conditions at TA-V, including recharge, hydraulics of vadose-zone and aquifer flow, and the aquifer field of flow as it pertains to downgradient receptors. The summary also discusses characterization of contaminant transport in the subsurface, including discussion about source term inventory, release, and contaminant distribution and transport in the vadose zone and aquifer.

  13. Conceptual Design of Object Oriented Program (OOP) for Pilot Code of Two-Fluid, Three-field Model with C++ 6.0

    International Nuclear Information System (INIS)

    Engineering software for design purpose in nuclear industries have been developed since early 1970s, and well established in 1980s. The most popular and common language for the software development has been FORTRAN series, until the more sophisticated GUI and software coupling is needed. The advanced computer language, such as C++, C has been developed to help the programming for the easy GUI need and reuse of well developed routines, with adopting the objective oriented program. A recent trend of programming becomes objective-oriented since the results are often more intuitive and easier to maintain than procedure program. The main motivation of this work is to capture objective oriented concepts for conventional safety analysis programs which consist of many functions and procedure oriented structures. In this work, the new objective programming with C++ 6.0 language has been tried for the PILOT code written in FORTRAN language, and conceptual OOP design of the system safety analysis code has been done

    A number of uncertainties exist in the hydrogeology of the Hanford Site, and the high costs and risks associated with cleanup of sites contaminated with radioactive wastes requires that the uncertainty associated with alternative remediation decisions must fully reflect the uncertainty associated with these decisions. Prior uncertainty analyses of Hanford groundwater model predictions have focused on uncertainties in model parameters (e.g., hydraulic conductivity) given an assumed conceptual model of hydrogeologic structure. In this study we evaluated predictive uncertainty related to the model structure conceptualization. Our study has focused on two major elements of the hydrogeologic structure of the Hanford Site: the geometry of mud units that occur within the aquifer, and the parameter zonation for hydrologic properties of the uppermost conductive portion of the aquifer. For each structural element, we have developed alternative conceptual models that have been evaluated by inverse modeling. The geometry and continuity of mud units exert a strong influence on groundwater flow and contaminant transport at the site. A detailed study of the spatial distribution of the three mud units was performed using a data set consisting of the presence/absence of each mud unit at several hundred boreholes, as well as the thickness if a mud unit was present. The spatial analysis proceeded in two stages. A series of stochastic simulations of the mud units were prepared using geostatistical methods. The stochastic simulations were numerically ranked and a subset of the best and worst simulations (as determined by the connectedness of the aquifer given the simulated mud distributions) was used as inputs to an inverse model. Inverse modeling was performed using UCODE and a finite element flow and transport code (CFEST) and used to test the fit of over 76,000 observed potentiometric head data for several alternative models of the mud distribution. Those conceptual models included

    Eckels Anderson, Chessa

    This study contributed to the body of research that supports a holistic model of afterschool learning through the design of an afterschool intervention that benefits elementary school students of low socioeconomic status. This qualitative study evaluated a science focused afterschool curriculum that was designed using principles from Risk and Resiliency Theory, academic motivation theories, science core ideas from the Next Generation Science Standards, and used environmental education philosophy. The research question of this study is: how does an outdoor and STEM based afterschool program impact at-risk students' self-efficacy, belonging and engagement and ability to apply conceptual knowledge of environmental science topics? The study collected information about the participants' affective experiences during the intervention using structured and ethnographic observations and semi-structured interviews. Observations and interviews were coded and analyzed to find patterns in participants' responses. Three participant profiles were developed using the structured observations and ethnographic observations to provide an in depth understanding of the participant experience. The study also assessed the participants' abilities to apply conceptual understanding of the program's science topics by integrating an application of conceptual knowledge task into the curriculum. This task in the form of a participant project was assessed using an adapted version of the Portland Metro STEM Partnership's Application of Conceptual Knowledge Rubric. Results in the study showed that participants demonstrated self-efficacy, a sense of belonging and engagement during the program. Over half of the participants in the study demonstrated a proficient understanding of program concepts. Overall, this holistic afterschool program demonstrated that specific instructional practices and a multi-modal science curriculum helped to support the social and emotional needs of at-risk children.

    K & S operates the largest and one of the most comprehensive Accredited Dosimetry Calibration Laboratories (ADCLs) in the American Association of Physicists in Medicine (AAPM) secondary laboratory system. It offers calibrations covering energies from Grenz-Ray (0.03-mm Al) to cesium-137 and cobalt-60, brachytherapy source and well chamber calibrations for low-activity sources, and, recently, high-dose-rate iridium-192. The present Quality Assurance (QA) program at K & S began with the AAPM Guidelines for Accreditation (Task Group No. 22 and No. 3, 1989) and grew over the past 10 years to include all aspects of providing a private, self-supporting calibration service from a free-standing independent facility. Some aspects of the QA program were prompted by the requirements of the nuclear power industry while other parts were from national consensus standards or the experiences of staff. Redundancy and teamwork are the most important characteristics of this QA program. K & S has participated in a National Institute of Standards and Technology (NIST) measurement quality assurance (MQA) program since 1982, and, in recent years, an ADCL intralaboratory intercomparison was conducted by Task Group 3 of the Radiation Therapy Committee of the AAPM. One measure of the credibility of a QA program is consistent performance on the MQA program and the ADCL intercomparisons over the past 10 years. An equally important measure of the ability of a program to assure quality results is the frequency of reported errors.

    Plasma wakefield acceleration has the potential to dramatically shrink the size and cost of particle accelerators. Research at the SLAC National Accelerator Laboratory has demonstrated that plasmas can provide 1,000 times the acceleration in a given distance compared with current technologies. Developing revolutionary and more efficient acceleration techniques that allow for an affordable high-energy collider is the focus of FACET, a National User Facility at SLAC. The existing FACET National User Facility uses part of SLAC’s two-mile-long linear accelerator to generate high-density beams of electrons and positrons. FACET-II is a new test facility to develop advanced acceleration and coherent radiation techniques with high-energy electron and positron beams. It is the only facility in the world with high energy positron beams. FACET-II provides a major upgrade over current FACET capabilities and the breadth of the potential research program makes it truly unique. It will synergistically pursue accelerator science that is vital to the future of both advanced acceleration techniques for High Energy Physics, ultra-high brightness beams for Basic Energy Science, and novel radiation sources for a wide variety of applications. The design parameters for FACET-II are set by the requirements of the plasma wakefield experimental program. To drive the plasma wakefield requires a high peak current, in excess of 10kA. To reach this peak current, the electron and positron design bunch size is 10μ by 10μ transversely with a bunch length of 10μ. This is more than 200 times better than what has been achieved at the existing FACET. The beam energy is 10 GeV, set by the Linac length available and the repetition rate is up to 30 Hz. The FACET-II project is scheduled to be constructed in three major stages. Components of the project discussed in detail include the following: electron injector, bunch compressors and linac, the positron system, the Sector 20 sailboat and W chicanes

    The first implementation of the AGATA spectrometer consisting of five triple germanium detector clusters has been installed at Laboratori Nazionali di Legnaro, INFN. This setup has two major goals, the first one is to validate the {gamma}-tracking concept and the second is to perform an experimental physics program using the stable beams delivered by the Tandem-PIAVE-ALPI accelerator complex. A large variety of physics topics will be addressed during this campaign, aiming to investigate both neutron and proton-rich nuclei. The setup has been designed to be coupled with the large-acceptance magnetic-spectrometer PRISMA. Therefore, the in-beam prompt {gamma} rays detected with AGATA will be measured in coincidence with the products of multinucleon-transfer and deep-inelastic reactions measured by PRISMA. Moreover, the setup is versatile enough to host ancillary detectors, including the heavy-ion detector DANTE, the {gamma}-ray detector array HELENA, the Cologne plunger for lifetime measurements and the Si-pad telescope TRACE. In this paper the design, characteristics and performance figures of the setup will be described.

  8. Discussion about Conceptual Framework

    2015-05-01

    Full Text Available Standard setters and most academics maintain that accounting standards ought to rest on a set of guiding principles stated explicitly in a “conceptual framework.” The FASB and IASB are currently involved in a project to refine conceptual framework documents developed earlier. At this point, it is not clear what their final product will look like; its defining characteristics as well as the substantive content can only be surmised. This paper addresses the issues that FASB and IASB face, including the question of what a conceptual framework should be all about. First, the paper describes and illustrates the current conceptual framework and the attitude of FASB and IASB. Second, the paper suggests characteristics that a conceptual framework ought to exhibit. Most of these suggestions are based on our critique of the existing framework and the FASB-IASB work in progress.

  12. System surveillance program at Cernavoda NPP

    International Nuclear Information System (INIS)

    The system Surveillance Program (SSP) is an industry accepted practice that has evolved over a number of years to the point where it is now recognized as the optimum way of ensuring system health. The SSP at Cernavoda is based on INPO good practices. It is a team effort coordinated and monitored by the system engineer (SE) and is designed to satisfy the following general purposes: - to ensure the station is operated and maintained in such a manner to be consistent with the operating license, operating policies and principles, design intent and safety analysis assumptions; - to ensure the systems are operated and maintained in such a manner to optimize reliability while being cost effective; - to ensure that systems and equipment performance is routinely monitored and, when necessary, a diagnostic testing program and subsequent corrective actions are implemented to predict and prevent potential future degradation. The SSP as described in this document applies to all systems. For all systems benefits in terms of cost savings, reliability, environmental protection and other key results can be achieved. This program is a dynamic process which is modified and improved based on the feedback from people the experience of whom in performing their tasks is used. Since many work groups are involved in implementing this program it is important to understand that good communication, information flow and a proactive attitude of all personnel are major prerequisites in developing a successful SSP at Cernavoda NPP. The document has the following contents: 1. Introduction; 2. Program implementation; 2.1. System surveillance specification; 2.2. SE tasks to implement the program; 2.2.1. System walkdowns; 2.2.2. Review performance and maintenance history; 2.2.3. Records keeping; 2.3. Reporting methods; 2.4. Supervisory requirements; 3. Some program implementation results; 4. Conclusion

    Historically, uranium was disposed in waste solutions of varying waste chemistry at the Hanford Site Central Plateau. The character of how uranium was distributed in the vadose zone during disposal, how it has continued to migrate through the vadose zone, and the magnitude of potential impacts on groundwater are strongly influenced by geochemical reactions in the vadose zone. These geochemical reactions can be significantly influenced by the disposed-waste chemistry near the disposal location. This report provides conceptual models and supporting information to describe uranium fate and transport in the vadose zone for both acidic and alkaline wastes discharged at a substantial number of waste sites in the Hanford Site Central Plateau. The conceptual models include consideration of how co-disposed acidic or alkaline fluids influence uranium mobility in terms of induced dissolution/precipitation reactions and changes in uranium sorption with a focus on the conditions near the disposal site. This information, when combined with the extensive information describing uranium fate and transport at near background pH conditions, enables focused characterization to support effective fate and transport estimates for uranium in the subsurface.

    beginning, the design studies at Jefferson Lab have focused on achieving high collider performance, particularly ultrahigh luminosities up to 10{sup 34} cm{sup -2}s{sup -1} per detector with large acceptance, while maintaining high polarization for both the electron and light-ion beams. These are the two key performance requirements of a future electron-ion collider facility as articulated by the NSAC Long Range Plan. In MEIC, a new ion complex is designed specifically to deliver ion beams that match the high bunch repetition and highly polarized electron beam from CEBAF. During the last two years, both development of the science case and optimization of the machine design point toward a medium-energy electron-ion collider as the topmost goal for Jefferson Lab. The MEIC, with relatively compact collider rings, can deliver a luminosity above 10{sup 34} cm{sup -2}s{sup -1} at a center-of-mass energy up to 65 GeV. It offers an electron energy up to 11 GeV, a proton energy up to 100 GeV, and corresponding energies per nucleon for heavy ions with the same magnetic rigidity. This design choice balances the scope of the science program, collider capabilities, accelerator technology innovation, and total project cost. An energy upgrade could be implemented in the future by adding two large collider rings housed in another large tunnel to push the center-of-mass energy up to or exceeding 140 GeV. After careful consideration of an alternative electron energy recovery linac on ion storage ring approach, a ring-ring collider scenario at high bunch repetition frequency was found to offer fully competitive performance while eliminating the uncertainties of challenging R&D on ampere-class polarized electron sources and many-pass energy-recovery linacs (ERLs). The essential new elements of an MEIC facility at Jefferson Lab are an electron storage ring and an entirely new, modern ion acceleration and storage complex. For the high-current electron collider ring, the upgraded 12 GeV CEBAF SRF

    The Oak Ridge National Laboratory (ORNL) is a US Department of Energy (DOE) facility that is managed by UT-Battelle, LLC. In February 2006, DOE promulgated worker safety and health regulations to govern contractor activities at DOE sites. These regulations, which are provided in 10 CFR 851, Worker Safety and Health Program, establish requirements for worker safety and health program that reduce or prevent occupational injuries, illnesses, and accidental losses by providing DOE contractors and their workers with safe and healthful workplaces at DOE sites. The regulations state that contractors must achieve compliance no later than May 25, 2007. According to 10 CFR 851, Subpart C, Specific Program Requirements, contractors must have a structured approach to their worker safety and health programs that at a minimum includes provisions for pressure safety. In implementing the structured approach for pressure safety, contractors must establish safety policies and procedures to ensure that pressure systems are designed, fabricated, tested, inspected, maintained, repaired, and operated by trained, qualified personnel in accordance with applicable sound engineering principles. In addition, contractors must ensure that all pressure vessels, boilers, air receivers, and supporting piping systems conform to (1) applicable American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (2004) Sections I through XII, including applicable code cases; (2) applicable ASME B31 piping codes; and (3) the strictest applicable state and local codes. When national consensus codes are not applicable because of pressure range, vessel geometry, use of special materials, etc., contractors must implement measures to provide equivalent protection and ensure a level of safety greater than or equal to the level of protection afforded by the ASME or applicable state or local codes. This report documents the work performed to address legacy pressure vessel deficiencies and comply

    The Idaho INEL Oversight Program, in association with the University of Idaho, Idaho Geological Survey, Boise State University, and Idaho State University, developed a research program to determine the hydraulic properties of the Snake River Plain aquifer and characterize the vertical distribution of contaminants. A straddle-packer was deployed in four observation wells near the Idaho Chemical Processing Plant at the Idaho National Engineering Laboratory. Pressure transducers mounted in the straddle-packer assembly were used to monitor the response of the Snake River Plain aquifer to pumping at the ICPP production wells, located 2600 to 4200 feet from the observation wells. The time-drawdown data from these tests were used to evaluate various conceptual models of the aquifer. Aquifer properties were estimated by matching time-drawdown data to type curves for partially penetrating wells in an unconfined aquifer. This approach assumes a homogeneous and isotropic aquifer. The hydraulic properties of the aquifer obtained from the type curve analyses were: (1) Storativity = 3 x 10{sup -5}, (2) Specific Yield = 0.01, (3) Transmissivity = 740 ft{sup 2}/min, (4) Anisotropy (Kv:Kh)= 1:360.

    Video analysis, using the program Tracker (Open Source Physics), in the educational process introduces a new creative method of teaching physics and makes natural sciences more interesting for students. This way of exploring the laws of nature can amaze students because this illustrative and interactive educational software inspires them to think creatively, improves their performance and helps them in studying physics. This paper deals with increasing the key competencies in engineering by analysing real-life situation videos - physical problems - by means of video analysis and the modelling tools using the program Tracker and simulations of physical phenomena from The Physics Education Technology (PhET™) Project (VAS method of problem tasks). The statistical testing using the t-test confirmed the significance of the differences in the knowledge of the experimental and control groups, which were the result of interactive method application.

    1996-12-31

    Since initiation in mid 1994, a bioscience nuclear microscopy program at Livermore has enabled collaboration with bio-scientists on a variety of projects requiring quantitative elemental microanalysis. For microprobe analysis a combination of PIXE and STIM are typically used; respectively generating element distribution maps with micron scale spatial resolution, and projected densities and histological information with sub-micron spatial resolution. Current studies demonstrate the applicability of nuclear microscopy (particularly when combined with other analysis techniques) in environmental tracing, toxicology, carcinogenesis, and structural biology. The program currently uses {approximately}10 percent of the available time on a 10 MV tandem accelerator that is also applied to a variety of Accelerator Mass Spectrometry and other microprobe programs. The completion of a dedicated nuclear microprobe system, using a 5 SDH NEC 1.7 MV tandem accelerator and employing several energy dispersive x-ray detectors to improve x-ray counting rates, promises increased accelerator access, greater sample throughput and continued expansion of the program.

  2. Conceptual and Empirical Themes regarding the Design of Technology Transfer Programs: A Review of Wood Utilization Research in the United States

    Paul V. Ellefson

    2011-01-01

    Full Text Available Transfer of technologies produced by research is critical to innovation within all organizations. The intent of this paper is to take stock of the conceptual underpinnings of technology transfer processes as they relate to wood utilization research and to identify conditions that promote the successful transfer of research results. Conceptually, research utilization can be viewed from multiple perspectives, including the haphazard diffusion of knowledge in response to vague and imprecise demands for information, scanning of multiple information sources by individuals and organizations searching for useful scientific knowledge, engagement of third parties to organize research results and communicate them to potential users, and ongoing and active collaboration between researchers and potential users of research. Empirical evidence suggests that various types of programs can promote technology transfer (venture capital, angel investors, business incubators, extension services, tax incentives, and in-house entities, the fundamental effectiveness of which depends on research results that are scientifically valid and consistent with the information needs of potential users. Furthermore, evidence suggests preference toward programs that are appropriately organized and governed, suitably led and creatively administered, and periodically evaluated in accordance with clear standards of success.

  3. Conceptual Design of a 50-100 MW Electron Beam Accelerator System for the National Hypersonic Wind Tunnel Program

    International Nuclear Information System (INIS)

    The National Hypersonic Wind Tunnel program requires an unprecedented electron beam source capable of 1--2 MeV at a beam power level of 50--100 MW. Direct-current electron accelerator technology can readily generate high average power beams to approximately 5 MeV at output efficiencies greater than 90%. However, due to the nature of research and industrial applications, there has never been a requirement for a single module with an output power exceeding approximately 500 kW. Although a 50--100 MW module is a two-order extrapolation from demonstrated power levels, the scaling of accelerator components appears reasonable. This paper presents an evaluation of component and system issues involved in the design of a 50--100 MW electron beam accelerator system with precision beam transport into a high pressure flowing air environment

    Gas turbines in industrial and utility applications can help meet future national and worldwide power generation requirements. Turbine systems burning natural gas offer environmentally sound and economical power generation and cogeneration. Since U.S. demand alone will require up to 15 gigawatts per year of new and replacement capacity after the year 2000, the availability of Advanced Turbine Systems (ATS) to fill a share of this need will save significant amounts of fuel and benefit the environment. Implementation of the ATS Program will also keep U.S. manufacturers on the cutting ledge of turbine technology for power generation applications and enhance the nation`s economic competitiveness.

    2006-12-01

    Solar energetic particle events, cosmic rays, and relativistic electrons in the outer edge of the radiation belts produce single event upsets in the electronics and spacecraft charging on a host satellite located at a geostationary orbit. In order to determine the space weather environment for the host, particle instruments capable of measuring both electrons and protons in a wide energy range, with a large angular coverage but finite angular resolution are necessary. In order to adhere to resource limitations, including weight and power consumption and whether or not a host platform is spinning or three-axis stabilized, energetic particle instruments must be designed accordingly. I will present a conceptual overview of novel LANL instruments, specifically two-element collimated telescopes with solid-state sensors, and describe how the requirements for accurate space weather determination are met despite the resource limitations.

    The purpose of this report is to show how an integrated environmental monitoring at the municipal level may make it possible to roughly quantify and analyze different mass- and energy flows. The present system for environmental monitoring is to some extent unsatisfactory. Integrated environmental monitoring is defined as `a coordinated quantifying, analysis and presentation of all mass- and energy flows in air, water and soil within a geographically confined area`. Kommunlaadan is a conceptual model for this integrated environmental monitoring, where the municipality has been chosen as the basis for the collection and handling of environmental data. This approach may prove advantageous because the municipality is both a geographically confined area and a political/administrative decision-making body. Furthermore, the collection and analysis of data can take place in a decentralized way. The collection and storage of data together with knowledge about environmental effects may constitute a basis for decisions and priorities made in the municipality. Data to be coordinated in the model is of different types; mass flows crossing the municipal borders; production within the municipality; accumulation of material within the municipality and the state of the environment. The basis for treatment and presentation of environmental data is an integrated analysis of map information, point data and model-results in a geographical information system. The conceptual model can only be realised if it is built up by a number of sub-models, which can be integrated into a larger system. The information may then ideally be integrated into balances for mass- and energy flows at the provincial and national levels. 5 refs, 2 figs

    How to evaluate students' astronomy understanding is still an open question. Even though some methods and tools to help students have already been developed, the sources of students' difficulties and misunderstanding in astronomy is still unclear. This paper presents an investigation of the development of conceptual systems in astronomy by 50 engineering students, as a result of learning a general course on astronomy. A special tool called Conceptual Frameworks in Astronomy (CFA) that was initially used in 1989, was adapted to gather data for the present research. In its new version, the tool included 23 questions, and five to six optional answers were given for each question. Each of the answers was characterized by one of the four conceptual astronomical frameworks: pre-scientific, geocentric, heliocentric and sidereal or scientific. The paper describes the development of the tool and discusses its validity and reliability. Using the CFA we were able to identify the conceptual frameworks of the students at the beginning of the course and at its end. CFA enabled us to evaluate the paradigmatic change of students following the course and also the extent of the general improvement in astronomical knowledge. It was found that the measure of the students’ improvement (gain index) was g = 0.37. Approximately 45% of the students in the course improved their understanding of conceptual frameworks in astronomy and 26% deepened their understanding of the heliocentric or sidereal conceptual frameworks.

    The Zurich IMaging POLarimeter (ZIMPOL) developed at ETH Zurich and installed permanently at the Gregory Coude Telescope at Istituto Ricerche Solari Locarno (IRSOL) allows a polarimetric precision down to 10^-5 to be reached. This makes it possible to perform several accurate spectro-polarimetric measurements of scattering polarization and to investigate solar magnetic fields through the signatures of the Hanle and Zeeman effects. The research programs are currently being extended to monochromatic imaging of the Stokes vector with a recently installed Fabry-Perot rapidly tunable filter system with a narrow pass band of about 30mA. The spatial resolution is being improved by the installation of an Adaptive Optics system.

  18. Turbulence Spectra for Boundary-Layer Winds in Tropical Cyclones: A Conceptual Framework and Field Measurements at Coastlines

    A conceptual model is proposed for the characteristic sub-ranges in the velocity and temperature spectra in the boundary layer of tropical cyclones (hurricanes or typhoons). The model is based on observations and computation of radial and vertical profiles of the mean flow and turbulence, and on the interpretation of eddy mechanisms determined by shear (namely roll and streak structures near the surface), convection, rotation, blocking and sheltering effects at the ground/sea surface and in internal shear layers. The significant sub-ranges, as the frequency increases, are associated with larger energy containing eddies, shear and blocking, inertial transfer between large and small scales, and intense small-scale eddies generated near the surface caused by waves, coastal roughness change, and the buoyancy force associated with the evaporation of spray droplets. These sub-ranges vary with the locations at which the spectra are measured, i.e. the level in relation to the height of the peak mean velocity and the depth of the boundary layer, and the radius in relation to the eyewall radius and the outer-vortex radius . For two tropical cyclones (Nuri and Hagupit), experimental data were analyzed. Spectra were measured where is near to and using four 1-h long datasets at coastal towers, at 10- and 60-m heights for tropical cyclone Nuri, and at 60-m height for tropical cyclone Hagupit at the south China coast. The field measurements of spectra within the boundary layer show significant sub-ranges of self-similar energy spectra (lying between the length scale 1,000 m and the smallest scales less than 40 m) that are consistent with the above conceptual model of the surface layer. However, with very high wind speeds near the eyewall, the energy of the independently generated intense surface eddy motions, associated with surface waves and water droplets in the airflow, greatly exceeds the energies of the small scales in the inertial sub-range of the boundary layer, over

    The Laser Communication Relay Demonstration will feature a geostationary satellite communicating via optical links to multiple ground stations. The first ground station (GS-1) is the 1m OCTL telescope at Table Mountain in California. The optical link will utilize pulse position modulation (PPM) and differential phase shift keying (DPSK) protocols. The DPSK link necessitates that adaptive optics (AO) be used to relay the incoming beam into the single mode fiber that is the input of the modem. The GS-1 AO system will have two MEMS Deformable mirrors to achieve the needed actuator density and stroke limit. The AO system will sense the aberrations with a Shack-Hartmann wavefront sensor using the light from the communication link's 1.55 microns laser to close the loop. The system will operate day and night. The system's software will be based on heritage software from the Palm 3000 AO system, reducing risk and cost. The AO system is being designed to work at r(sub 0) greater than 3.3 cm (measured at 500 nm and zenith) and at elevations greater than 20deg above the horizon. In our worst case operating conditions we expect to achieve Strehl ratios of over 70% (at 1.55 microns), which should couple 57% of the light into the single mode DPSK fiber. This paper describes the conceptual design of the AO system, predicted performance and discusses some of the trades that were conducted during the design process.

  20. The research program at SIS/ESR

    International Nuclear Information System (INIS)

    A varied research program is currently in preparation for the expanded facility. Above one hundred experiments have been proposed following a call for proposals about 1 1/2 year ago, and have been reviewed by an international science committee. About half of the proposals were aimed at research in nuclear and nuclear-matter physics. These are discussed in more detail in the present overview. In addition, about 25% of the proposals were in the area of atomic physics, planning to make use of the capability of the new facility to strip even the heaviest ions into the innermost shells, with the additional possibility of subsequent cooling and deceleration. Biological research, utilizing the larger range of ions at elevated energies and thus deeper penetration and also irradiation in atmosphere, represented about 15% of the proposals; the rest was divided among various projects of applied research.

    With the Constellation Program, NASA is entering a new age of space exploration that will take us back to the Moon, to Mars, and beyond, and NASA is developing the new technology and vehicles to take us there. At the forefront are the Orion spacecraft and the Ares I launch vehicle. As NASA's gateway to space, Kennedy Space Center (KSC) will process and launch the new vehicles. This will require new systems and extensive changes to existing infrastructure. KSC is designing a new mobile launcher, a new launch control system, and new ground support equipment; modifying the Vehicle Assembly Building, one of the launch pads, and other facilities; and launching the Ares I-X flight test. It is an exciting and challenging time to be an engineer at KSC.

  2. What binds quarks together at different momentum scales? A conceptual scenario

    Directory of Open Access Journals (Sweden)

    N.G. Stefanis

    2014-11-01

    Full Text Available The binding effects of quarks within hadrons are discussed in terms of the pion distribution amplitude over longitudinal momentum fractions. To understand the behavior of this quantity at different momentum scales, the concept of synchronization in complex systems has been employed. It is argued that at low momentum scales, the quarks get correlated by nonlocal quark/gluon condensates that cause an endpoint-suppressed, mainly bimodal structure of the pion distribution amplitude inferred from a sum-rule analysis. The mass generation mechanism, within the framework of Dyson–Schwinger equations, and evolution effects pull these two peaks back to the center to form at Q2→∞ the asymptotic distribution amplitude which represents the most synchronized q¯q state.

  3. Feasibility and conceptual design of a C.W. positron source at CEBAF

    Energy Technology Data Exchange (ETDEWEB)

    2010-08-01

    A feasibility study of a CW positron source for the 12 GeV upgrade at Jefferson Lab (JLAB) is provided. The proposed ≥ 100 nA Continuous Wave (CW) positron source at JLAB has several unique and challenging characteristics: high current incident electron beam at 126 MeV with a high beam power (up to a MW); CW e- beam and CW e+ production. The multiple scattering is a dominant process when creating e+ in a target, which results a large phase space area of the emitted positrons. An admittance study was done at CEBAF to find the maximum phase space area, which is tolerated in the machine. The measured geometrical transverse admittance (A) were Ax =10 and Ay = 5 mm∙mrad at the injector. Energy spread measurement was also done at the ARC1. The fractional spread limit in the ARC1 was measured as δ = 3×10-3 at 653 MeV. By using the optimized results and the CEBAF parameters, three positron injector configurations are proposed; Combined Function Magnet, Two-Dipole and Microtron Dipole configurations. With the assumptions made, by using 126 MeV Ⓧ10 mA e- beam impinging on a 2 mm W target with a 100 μm spot size, we can get up to 3 μA useful e+ current at the North Linac connection. One of the biggest challenges is the target design, which the deposited power is about 60 kW. ILC designs project power deposition up to 13 kW, which would allow the creation of a e+ beam of up to 650 nA otherwise. The results of analytic and monte carlo simulations of the positron production, capture and acceleration are presented. For the target design, a review is presented of solutions for the high power production target. Portions of this dissertation work have been published in two conference proceedings.

    The potential for a superconducting proton linac (SPL) at CERN started to be seriously considered at the end of the 1990s. In the first conceptual design report (CDR), published in 2000 [1], most of the 352 MHz RF equipment from LEP was re-used in an 800 m long linac, and the proton beam energy was limited to 2.2 GeV. During the following years, the design was revisited and optimized to better match the needs of a high-power proton driver for neutrino physics. The result was a more compact (470 m long) accelerator capable of delivering 5 MW of beam power at 3.5 GeV, using state-of-the-art superconducting RF cavities at 704 MHz. It was described in a second CDR, published in 2006 [2]. Soon afterwards, when preparation for increasing the luminosity of the LHC by an order of magnitude beyond nominal became an important concern, a low-power SPL (LP-SPL) was studied as a key component in the renovation of the LHC injector complex. The combination of a 4 GeV LP-SPL injecting into a new 50 GeV synchrotron (PS2) was ...

  5. Conceptual design of a thermalhydraulic loop for multiple test geometries at supercritical conditions named Supercritical Phenomena Experimental Test Apparatus (SPETA)

    Science.gov (United States)

    Adenariwo, Adepoju

    The efficiency of nuclear reactors can be improved by increasing the operating pressure of current nuclear reactors. Current CANDU-type nuclear reactors use heavy water as coolant at an outlet pressure of up to 11.5 MPa. Conceptual SuperCritical Water Reactors (SCWRs) will operate at a higher coolant outlet pressure of 25 MPa. Supercritical water technology has been used in advanced coal plants and its application proves promising to be employed in nuclear reactors. To better understand how supercritical water technology can be applied in nuclear power plants, supercritical water loops are used to study the heat transfer phenomena as it applies to CANDU-type reactors. A conceptual design of a loop known as the Supercritical Phenomena Experimental Apparatus (SPETA) has been done. This loop has been designed to fit in a 9 m by 2 m by 2.8 m enclosure that will be installed at the University of Ontario Institute of Technology Energy Research Laboratory. The loop include components to safely start up and shut down various test sections, produce a heat source to the test section, and to remove reject heat. It is expected that loop will be able to investigate the behaviour of supercritical water in various geometries including bare tubes, annulus tubes, and multi-element-type bundles. The experimental geometries are designed to match the fluid properties of Canadian SCWR fuel channel designs so that they are representative of a practical application of supercritical water technology in nuclear plants. This loop will investigate various test section orientations which are the horizontal, vertical, and inclined to investigate buoyancy effects. Frictional pressure drop effects and satisfactory methods of estimating hydraulic resistances in supercritical fluid shall also be estimated with the loop. Operating limits for SPETA have been established to be able to capture the important heat transfer phenomena at supercritical conditions. Heat balance and flow calculations have

  13. Study of a conceptual nuclear energy center at Green River, Utah: water allocation issues

    International Nuclear Information System (INIS)

    According to preliminary studies, operation of a nine-reactor Nuclear Energy Center near Green River, Utah would require the acquisition of 126,630 acre-feet per year. Groundwater aquifers are a potential source of supply but do not present a viable option at this time due to insufficient data on aquifer characteristics. Surface supplies are available from the nearby Green and San Rafael Rivers, tributaries of the Colorado River, but are subject to important constraints. Because of these constraints, the demand for a dependable water supply for a Nuclear Energy Center could best be met by the acquisition of vested water rights from senior appropriators in either the Green or San Rafael Rivers. The Utah Water Code provides a set of procedures to accomplish such a transfer of water rights

  15. Graphical programming at Sandia National Laboratories

    International Nuclear Information System (INIS)

    Sandia has developed an advanced operational control system approach, called Graphical Programming, to design, program, and operate robotic systems. The Graphical Programming approach produces robot systems that are faster to develop and use, safer in operation, and cheaper overall than altemative teleoperation or autonomous robot control systems. Graphical Programming also provides an efficient and easy-to-use interface to traditional robot systems for use in setup and programming tasks. This paper provides an overview of the Graphical Programming approach and lists key features of Graphical Programming systems. Graphical Programming uses 3-D visualization and simulation software with intuitive operator interfaces for the programming and control of complex robotic systems. Graphical Programming Supervisor software modules allow an operator to command and simulate complex tasks in a graphic preview mode and, when acceptable, command the actual robots and monitor their motions with the graphic system. Graphical Programming Supervisors maintain registration with the real world and allow the robot to perform tasks that cannot be accurately represented with models alone by using a combination of model and sensor-based control

  16. A conceptual study of the proton storage ring for the Neutron Science Project at JAERI

    International Nuclear Information System (INIS)

    Japan Atomic Energy Research Institute, JAERI, has been proposing the Neutron Science Project (NSP) which is composed of research facilities based on a proton linac and a proton storage ring with an energy of 1.5 GeV. The proposed NSP is aiming at exploring new basic researches and nuclear technologies such as condensed matter physics and nuclear waste transmutation based on a proton accelerator. In the proton storage ring, the pulsed beam from the linac is accumulated, and high intensity pulsed beam is produced for the neutron scattering experiment. The goal of the proton storage ring is to provide a short pulsed proton beam of less than 1 μs with an average beam power of 5 MW with two rings. The study of the proton storage ring whose beam power is 2.5 MW has been performed. The proton storage ring is consisted of the High Energy Beam Transport (HEBT) line which connects the 1.5 GeV linac to the ring and the proton storage ring which really accumulates the protons. The beam coming out of the linac is a 1.5 GeV H beam and 1.86 ms long with a peak current of 30 mA. The beam is chopped to the pulse length of 400 ns with 270 ns gap. The beam is compressed by means of a multi-turn charge exchange injection. When a harmonic number of the ring is 1, a circumference and a revolution frequency are 185.4 m and 1.49 MHz, respectively. The single bunch in the ring is contained by rf cavity. To achieve a beam power of 2.5 MW with this beam structure, it is necessary to accumulate 2777 bunches. This corresponds to 2.08 x 1014 protons. When the beam injection is completed, accumulated protons are extracted from the ring during 1 turn. The average current circulating in the ring with 1.49 MHz revolution frequency becomes 49.75 A. At such a high average current, a beam loss of a very small fraction makes a very high radioactivity around the ring. It is necessary to examine reduction and localization of the beam loss with sufficient consideration of the divergence of the beam by

  17. Large superconductors and joints for fusion magnets: From conceptual design to testing at full scale

    International Nuclear Information System (INIS)

    A new kind of superconductor, using the cable-in-conduit concept, is emerging, mainly in the context of fusion activity. At present no large Nb3Sn magnet in the world is operating using this concept. The difficulty of this technology, which has now been studied for 20 years, is that it requires major advances in several interconnected new fields, such as handling a large number (1000) of superconducting strands, high current conductors (50 kA), forced flow cryogenics, Nb3Sn technology, low loss conductors in pulsed operation, high current connections and high voltage insulation (10 kV), as well as demonstration of its economical and industrial feasibility. CEA has been very much involved during the past ten years in this development, which took place in the framework of the NET and ITER technological programmes. One major milestone was reached in 1998-1999 with the successful tests by Euratom-CEA of three full size conductor and connection samples in the SULTAN facility in Switzerland. (author)

  18. Conceptual design of the hot cell facility universal docking station at ITER

    International Nuclear Information System (INIS)

    Between main shutdowns of the ITER machine, in-vessel components and Iter Remote Maintenance System (IRMS) are transferred between the Tokamak complex and the Hot Cell Facility using different types of sealed casks. Transfer Casks have different physical interfaces with the Vacuum Vessel, which need to be the same at the docking stations of the HCF. It means that in-vessel components and IRMS are cleaned in the same cells, which is in fact not convenient. Furthermore, logistic studies showed that the use rate of the cells is very inhomogeneous. In order to have dedicated cell for decontamination of Remote Handling tools, in order to increase the operability efficiency and to removes the hot cell docking operation from the critical path, the concept of a universal docking station has been investigated. Based on an existing design, the work was focused on a review of requirements, the re-design and the integration within the HCF layout. The universal docking station has been proposed and is now integrated in HCF design.

Transfer Casks have different physical interfaces with the Vacuum Vessel, which need to be the same at the docking stations of the HCF. It means that in-vessel components and IRMS are cleaned in the same cells, which is in fact not convenient. Furthermore, logistic studies showed that the use rate of the cells is very inhomogeneous. In order to have dedicated cell for decontamination of Remote Handling tools, in order to increase the operability efficiency and to removes the hot cell docking operation from the critical path, the concept of a universal docking station has been investigated. Based on an existing design, the work was focused on a review of requirements, the re-design and the integration within the HCF layout. The universal docking station has been proposed and is now integrated in HCF design.

  20. Conceptual design of covering method for the proposed LILW near-surface repository at Cernavoda

    International Nuclear Information System (INIS)

    The disposal concept of the low and intermediate level (LIL) wastes resulting during NPP operation combines both the natural and engineered barriers in order to ensure the safety of the environment and population. Saligny site has been proposed for LIL waste disposal. Preliminary performance assessments indicate that the loess and clay layers are efficient natural barriers against water flow and radionuclide migration through the vadose zone to the local aquifers. At present, the studies on site characterization are concentrated on investigation of the potential factors affecting the long-term integrity of the disposal facility. This analysis showed that surface erosion by wind and water and bio-intrusion by plant roots and burrowing animals could affect the long-term disposal safety. Based on the preliminary erosion results, as well as on the high probability of bio-intrusion by the plant roots and burrowing animals (i.e. moles, mice), different covering systems able to ensure the long-term safety of the repository has been proposed and analyzed. FEHM and HYDRUS 2D water flow simulations have been performed in order to compare their efficiency in the diminution of the infiltration rate in the repository. From this point of view, the covering system combining the capillary barrier and the resistive layer proved to have the best behavior

    Full Text Available The article is aimed at studying the current trends of regulatory policy in the global energy market and identifying potent ways for energy efficiency growth in terms of the Ukrainian economy. An analysis of the main trends of energy policy development in the world has been carried out and a priority direction for the development of Ukrainian energy on the basis of the biofuel industry has been determined. The article substantiates actuality of the matter that one of the main directions of overcoming the energy crisis in Ukraine, along with ensuring recovery and sustainable growth of the gross domestic product, is transition to the industrial use of biofuels. The process of production and consumption of biofuels must be seen as a means to raise the level of decentralization, while ensuring energy sources. It is determined that the State must provide information support for producers of biofuels, defining their market range and encouraging beneficial business partners. Increased production of biofuels in Ukraine will serve as a fundamental factor in achieving international competitiveness of the national economy, as well as its growth on innovation basis.

  2. Conceptual model analysis of interaction at a concrete-Boom Clay interface

    Liu, Sanheng; Jacques, Diederik; Govaerts, Joan; Wang, Lian

    In many concepts for deep disposal of high-level radioactive waste, cementitious materials are used in the engineered barriers. For example, in Belgium the engineered barrier system is based on a considerable amount of cementitious materials as buffer and backfill in the so-called supercontainer embedded in the hosting geological formation. A potential hosting formation is Boom Clay. Insight in the interaction between the high-pH pore water of the cementitious materials and neutral-pH Boom Clay pore water is required. Two problems are quite common for modeling of such a system. The first one is the computational cost due to the long timescale model assessments envisaged for the deep disposal system. Also a very fine grid (in sub-millimeter), especially at interfaces has to be used in order to accurately predict the evolution of the system. The second one is whether to use equilibrium or kinetic reaction models. The objectives of this paper are twofold. First, we develop an efficient coupled reactive transport code for this diffusion-dominated system by making full use of multi-processors/cores computers. Second, we investigate how sensitive the system is to chemical reaction models especially when pore clogging due to mineral precipitation is considered within the cementitious system. To do this, we selected two portlandite dissolution models, i.e., equilibrium (fastest) and diffusion-controlled model with precipitation of a calcite layer around portlandite particles (diffusion-controlled dissolution). The results show that with shrinking core model portlandite dissolution and calcite precipitation are much slower than with the equilibrium model. Also diffusion-controlled dissolution smooths out dissolution fronts compared to the equilibrium model. However, only a slight difference with respect to the clogging time can be found even though we use a very small diffusion coefficient (10-20 m2/s) in the precipitated calcite layer.

  3. A Conceptual Study of Hybrid System for Nuclear Energy Generation and Transmutation at CIAE

    International Nuclear Information System (INIS)

    Energy supply is a severe problem for developing country. Nuclear energy is just at its start in China. For developing nuclear energy three aspects must considered: 1. Nuclear waste handled properly: 2. Nuclear power station safety improved; 3. Natural Uranium resource utilization factor increased and new applicable resources expected. A research group for accelerator driven subcritical reactor in China Institute of Atomic Energy has been working for two years. Research results indicated subcritical reactor nuclear system driven by high intensity proton current accelerator can meet these requirements, that is 1. Subcritical reactor safety is accessible for the public 2. Some Short-lived. Low poison nuclear waste is removed from nuclear system, that is radioactive clean. 3. U-238 and Th-232 in the subcritical reactor can be converted into stationary nuclear fuel inventory to generate nuclear energy. The research results also indicated that the theoretical basis is right for accelerator driven subcritical reactor nuclear energy system, and has technological advantages for the further development of nuclear energy system which is different from conventional nuclear energy system, it's a technological innovation way for development of nuclear energy. During the early time of nuclear power exploitation and application in our country, it is worth to exploit this novel technological option.In this paper, discussion on the transmutation concept of high-level radioactive nuclide in nuclear waste is firstly conducted. And Then a brief description to the basic principle of ADS is given. The fission in the subcritical reactor with external neutron source is discussed. The relation ship of energy gain of the system, external neutron source with the subcritical reactor k is also discussed. (Author) 12 refs

    The next generation all-sky monitor operating at TeV (0.1 - 30 TeV) energies should be capable of performing a continuous high sensitivity sky survey, and detecting transient sources, such as AGN flares, with high statistical significance on timescales of hours to days. We describe an instrument concept for a large area, wide aperture, TeV ground-based Gamma-ray telescope. The conceptual design is comprised of 20000 sqm scintillator-based pixels arranged in a densely packed mosaic. In addition to fast timing, the dense array of pixels also provides a unique imaging capability; the shower image, the spatial distribution of secondary particles at ground level, can be exploited to identify and reject hadronic backgrounds. The good angular resolution and background rejection capabilities lead directly to high sensitivity, while retaining a large field of view, large effective area, and high duty cycle. An instrument such as the one described here complements the narrow field of view air-Cherenkov telescopes and c...

  5. Conceptual and numerical modelling of radionuclide transport in near-surface systems at Forsmark. SR-Site Biosphere

    International Nuclear Information System (INIS)

    In the framework of the SR-Site safety assessment, a conceptual and numerical modelling of radionuclide reactive transport in near-surface systems (including till and clay systems) at Forsmark has been carried out. The objective was to evaluate the retention capacity of the near-surface systems, composed of Quaternary deposits, which would be the last natural barrier for an eventual radionuclide release from the deep repository prior to reaching the biosphere. The studied radionuclides are 14C, 129I, 36Cl, 94Nb, 59Ni, 93Mo, 79Se, 99Tc, 230Th, 90Sr, 226Ra, 135Cs and U. Conceptual description and numerical simulations of radionuclide reactive transport show that cation exchange and surface complexation on illite are active processes for the retention of several radionuclides (U, Th, Ni, Cs, Sr, Ra). Surface complexation on iron hydroxide is an active process in the till system, able to effectively retain U and Ni. Another retention process of importance is the incorporation of the radionuclides into mineral phases, either by the precipitation of pure phases or solid solutions. Quantitative modelling has been useful to illustrate the incorporation of C and Sr in the carbonate solid solution in the considered model domains (till and clay), as well as the precipitation of uraninite in the clay sediments and the precipitation of native selenium and radiobarite in the till. Other mineral phases that could, a priori, retain U, Se, Nb and Tc do not precipitate in the simulations, either due to the pH-Eh conditions and/or because the dissolved concentration of the element is not high enough under the considered simulation conditions. It is important to keep in mind that changes in these parameters and in the boundary conditions could modify the predicted behaviour of these elements. The radionuclides that are most significantly retarded are Th, Ni and Cs, mainly through sorption onto illite. Therefore, if the amount of illite (or available sorption sites) decreases, the

    Global biogeochemical cycles have been deeply modified by human activities in recent decades. But detailed studies analyzing the influence of current economic and social organizations on global biogeochemical cycles within a system perspective are still required. Country level offers a relevant scale for assessing nutrient management and identifying key driving forces and possible leaks in the nutrient cycle. Conceptual modeling helps to quantify nutrient flows within the country and we developed such an approach for France. France is a typical Western European country with intensive agriculture, trade and an affluent diet, all of which may increase internal and external P flows. Phosphorus (P) was taken as a case study because phosphate rock is a non-renewable resource which future availability is becoming increasingly bleak. A conceptual model of major P flows at the country scale was designed. France was divided into agriculture, industry, domestic, import and export sectors, and each of these sectors was further divided into compartments. A total of 25 internal and eight external P flows were identified and quantified on a yearly basis for a period of 16 years (from 1990 to 2006) in order to understand long-term P flows. All the P flows were quantified using the substance flow analysis principle. The results showed that the industrial sector remained the largest contributor to P flows in France, followed by the agriculture and domestic sectors. Soil P balance was positive. However, a positive P balance of 18 kg P ha-1 in 1990 was reduced to 4 kg P ha-1 in 2006, mainly due to the reduced application of inorganic P fertilizer. The overall country scale P balance was positive, whereas half of this additional P was lost to the environment mainly through the landfilling of municipal and industrial waste, disposal of treated wastewater from which P was partially removed, and P losses from agricultural soils though erosion and leaching. Consequences for global P

    This paper provides an overview of Systems Engineering as it is applied in a conceptual design space systems department at the National Aeronautics and Space Administration (NASA) Marshall Spaceflight Center (MSFC) Advanced Concepts Office (ACO). Engineering work performed in the NASA MFSC's ACO is targeted toward the Exploratory Research and Concepts Development life cycle stages, as defined in the International Council on Systems Engineering (INCOSE) System Engineering Handbook. This paper addresses three ACO Systems Engineering tools that correspond to three INCOSE Technical Processes: Stakeholder Requirements Definition, Requirements Analysis, and Integration, as well as one Project Process Risk Management. These processes are used to facilitate, streamline, and manage systems engineering processes tailored for the earliest two life cycle stages, which is the environment in which ACO engineers work. The role of systems engineers and systems engineering as performed in ACO is explored in this paper. The need for tailoring Systems Engineering processes, tools, and products in the ever-changing engineering services ACO provides to its customers is addressed.

  12. A comparative evaluation of conceptual models for the Snake River Plain aquifer at the Idaho Chemical Processing Plant, INEL

    International Nuclear Information System (INIS)

    Geologic and hydrologic data collected by the United States Geological Survey (USGS) are used to evaluate the existing ground water monitoring well network completed in the upper portion of the Snake River Plain aquifer (SRPA) beneath the Idaho Chemical Processing Plant (ICPP). The USGS data analyzed and compared in this study include: (a) lithologic, geophysical, and stratigraphic information, including the conceptual geologic models intrawell, ground water flow measurement (Tracejector tests) and (c) dedicated, submersible, sampling group elevations. Qualitative evaluation of these data indicate that the upper portion of the SRPA is both heterogeneous and anisotropic at the scale of the ICPP monitoring well network. Tracejector test results indicate that the hydraulic interconnection and spatial configuration of water-producing zones is extremely complex within the upper portion of the SRPA. The majority of ICPP monitoring wells currently are equipped to sample ground water only the upper lithostratigraphic intervals of the SRPA, primarily basalt flow groups E, EF, and F. Depth-specific hydrogeochemical sampling and analysis are necessary to determine if ground water quality varies significantly between the various lithostratigraphic units adjacent to individual sampling pumps

    This report addresses issues related to the analysis of uncertainty in dose assessments conducted as part of decommissioning analyses. The analysis is limited to the hydrologic aspects of the exposure pathway involving infiltration of water at the ground surface, leaching of contaminants, and transport of contaminants through the groundwater to a point of exposure. The basic conceptual models and mathematical implementations of three dose assessment codes are outlined along with the site-specific conditions under which the codes may provide inaccurate, potentially nonconservative results. In addition, the hydrologic parameters of the codes are identified and compared. A methodology for parameter uncertainty assessment is outlined that considers the potential data limitations and modeling needs of decommissioning analyses. This methodology uses generic parameter distributions based on national or regional databases, sensitivity analysis, probabilistic modeling, and Bayesian updating to incorporate site-specific information. Data sources for best-estimate parameter values and parameter uncertainty information are also reviewed. A follow-on report will illustrate the uncertainty assessment methodology using decommissioning test cases.

    2012-10-01

    Public accountability has re-emerged as a top priority for health systems all over the world, and particularly in developing countries where governments have often failed to provide adequate public sector services for their citizens. One approach to strengthening public accountability is through direct involvement of clients, users or the general public in health delivery, here termed 'community accountability'. The potential benefits of community accountability, both as an end in itself and as a means of improving health services, have led to significant resources being invested by governments and non-governmental organizations. Data are now needed on the implementation and impact of these initiatives on the ground. A search of PubMed using a systematic approach, supplemented by a hand search of key websites, identified 21 papers from low- or middle-income countries describing at least one measure to enhance community accountability that was linked with peripheral facilities. Mechanisms covered included committees and groups (n = 19), public report cards (n = 1) and patients' rights charters (n = 1). In this paper we summarize the data presented in these papers, including impact, and factors influencing impact, and conclude by commenting on the methods used, and the issues they raise. We highlight that the international interest in community accountability mechanisms linked to peripheral facilities has not been matched by empirical data, and present a conceptual framework and a set of ideas that might contribute to future studies.

    2012-09-01

    GlueX is one of the flagship experiments of the 12 GeV era at the Thomas Jefferson National Accelerator Facility (JLab). The energy of the electron accelerator at JLab is presently undergoing an upgrade from 6 GeV to 12 GeV and a 4th experimental hall (Hall D) is being added. The GlueX experimental apparatus consists of a tagged coherent bremsstrahlung photon beam incident on a liquid hydrogen target. The photoproduced mesons, which are created inside of a 2.2 T solenoid, will then pass through a pair of drift chambers and eventually deposit their energy into either of two calorimeters, depending on their respective angles. GlueX will attempt to map out the light meson spectrum and search for meson-gluon hybrids to better understand the confinement of quarks and gluons in quantum chromodynamics (QCD). There is little data on the photoproduction of light mesons and the GlueX experiment will exceed the current photoproduction data by several orders of magnitude in the first year alone. Photoproduction is specifically well suited to search for meson-gluon hybrids because in the flux tube model the production cross-sections are higher for meson-gluon hybrids from photons, with the spins of the virtual quark-antiquark pair aligned, than from other sources such as pions, with the spins of the quark-antiquark pair anti-aligned. There are also other Hall D experiments proposed to look for physics beyond the Standard Model by studying Eta rare or forbidden decay channels such as eta to two neutral pions. The 12 GeV upgrade of the JLab accelerator and the complete physics program of Hall D will be presented.

    Full Text Available The nuclear data program at the Rensselaer Polytechnic Institute (RPI is centered around a 60 MeV pulsed electron Linear Accelerator (LINAC configured to deliver pulsed neutron beams. The LINAC electron pulse width can vary between 5 ns and 5 us, a repetition rate of 1–500 pulses per second and neutron yield of up to 1013 n/s. Over the years several experimental setups and techniques were developed to enable a variety of measurement capabilities. The experiments cover the energy range from 0.001 eV to 20 MeV and included neutron transmission, capture, scattering and fission measurements. The facility is also equipped with a Lead Slowing-Down Spectrometer (LSDS producing a high neutron flux that is used for simultaneous measurements of the fission cross section and fission fragment mass and energy distributions. Detectors for (n, alpha and (n, p cross section measurements using the LSDS were also developed and measurements of (n, alpha cross section were completed. The high neutron flux inside the LSDS enables measurements on small samples (sub micrograms or samples with small cross section (sub millibarns. In order to fully utilize the capabilities of the facility, several measurement techniques were developed; high accuracy (<1% total cross sections were measured using iron and uranium filtered neutron beams. A system for fast neutron scattering measurements using an array of liquid scintillators and a digital data acquisition system was recently developed and used for several measurements and is now being adapted for fission neutron studies. Methods for simultaneous measurements of fission and capture cross sections using the RPI multiplicity detector are under development and new modular detectors for both fast and resonance region neutron detection were developed and deployed. These developments result in numerous measurements on different materials and provide input to improved evaluated nuclear data libraries and thus help

  9. PHENIX Conceptual Design Report. An experiment to be performed at the Brookhaven National Laboratory Relativistic Heavy Ion Collider

    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The e{mu} coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study {pi}{sup 0} and {eta} production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the {phi} meson (via K{sup +}K{sup {minus}} decay), jets, and two-boson correlations. The measurements are made down to small cross sections to allow the study of high p{sub T} spectra, and J/{psi} and {Upsilon} production. The PHENIX collaboration consists of over 300 scientists, engineers, and graduate students from 43 institutions in 10 countries. This large international collaboration is supported by US resources and significant foreign resources.

    Energy Technology Data Exchange (ETDEWEB)

    Sheffield, J.

    1999-05-11

    Energy availability in a country is of great importance to its economy and to raising and maintaining its standard of living. In 1994, the United States consumed more than 88 quadrillion Btu (quads) of energy and spent about $500 billion on fuels and electricity. Fortunately, the United States is well endowed with energy sources, notably fossil fuels, and possesses a considerable nuclear power industry. The United States also has significant renewable energy resources and already exploits much of its hydropower resources, which represent 10% of electricity production. Nevertheless, in 1994, the United States imported about 45% of the petroleum products it consumed, equivalent to about 17 quads of energy. This dependence on imported oil puts the country at risk of energy supply disruptions and oil price shocks. Previous oil shocks may have cost the country as much as $4 billion (in 1993 dollars) between 1973 and 1990. Moreover, the production and use of energy from fossil fuels are major sources of environmental damage. The corresponding situation in many parts of the world is more challenging. Developing countries are experiencing rapid growth in population, energy demand, and the environmental degradation that often results from industrial development. The near-term depletion of energy resources in response to this rapid growth runs counter to the concept of ''sustainable development''--development that meets the needs of today without compromising the ability of future generations to meet their own needs. Energy research and development (R&D) to improve efficiency and to develop and deploy energy alternatives may be viewed, therefore, as an insurance policy to combat the dangers of oil shocks and environmental pollution and as a means of supporting sustainable development. These considerations guide the energy policy of the United States and of the U.S. Department of Energy (DOE). In its strategic plan, DOE identifies the fostering of &apos

  16. Restructured site characterization program at Yucca Mountain

    International Nuclear Information System (INIS)

    During 1994 and the early part of 1995, the US Department of Energy's Yucca Mountain Site Characterization Office (YMSCO) and its parent organization, the Office of Civilian Radioactive Waste Management (OCRWM) underwent a significant restructuring. Senior Department officials provided the leadership to reorient the management, technical, programmatic, and public interaction approach to the US High Level Radioactive Waste Disposal Program. The restructuring involved reorganizing the federal staff, conducting meaningful strategic planning, improving the management system, rationalizing contractor responsibilities, focusing upon major products, and increasing stakeholder involvement. The restructured program has prioritized technical and scientific activities toward meeting major regulatory milestones in a timely and cost-effective manner. This approach has raised concern among elements of technical, scientific, and oversight bodies that suitability and licensing decisions could be made without obtaining sufficient technical information for this first-of-its-kind endeavor. Other organizations, such as congressional committees, industrial groups, and rate payers believe characterization goals can be met in a timely manner and within the limitation of available funds. To balance these contrasting views in its decision making process, OCRWM management has made a special effort to communicate its strategy to oversight bodies, the scientific community and other stakeholders and to use external independent peer review as a key means of demonstrating scientific credibility. Site characterization of Yucca Mountain in Nevada is one of the key elements of the restructured program

  20. Conceptual design report for a superconducting coil suitable for use in the large solenoid detector at the SSC [Superconducting Super Collider

    International Nuclear Information System (INIS)

    The conceptual design of a large superconducting solenoid suitable for a magnetic detector at the Superconducting Super Collider (SSC) was done at Fermilab. The magnet will provide a magnetic field of 1.7 T over a volume 8 m in diameter by 16 m long. The particle-physics calorimetry will be inside the field volume and so the coil will be bath cooled and cryostable; the vessels will be stainless steel. Predictability of performance and the ability to safely negotiate all probable failure modes, including a quench, are important items of the design philosophy. Our conceptual design of the magnet and calorimeter has convinced us that this magnet is a reasonable extrapolation of present technology and is therefore feasible. The principal difficulties anticipated are those associated with the very large physical dimensions and stored energy of the magnet. 5 figs

    Negative ion Experimental facility has been setup at IPR. The facility consists of a RF based negative ion source (ROBIN)—procured under a license agreement with IPP Garching, as a replica of BATMAN, presently operating in IPP, 100 kW 1 MHz RF generators and a set of low and high voltage power supplies, vacuum system and diagnostics. 35 keV 10A H- beam is expected from this setup. Automated successful operation of the system requires an advanced, rugged, time proven and flexible control system. Further the data generated in the experimental phase needs to be acquired, monitored and analyzed to verify and judge the system performance. In the present test bed, this is done using a combination of PLC based control system and a PXI based data acquisition system. The control system consists of three different Siemens PLC systems viz. (1) S-7 400 PLC as a Master Control, (2) S-7 300 PLC for Vacuum system control and (3) C-7 PLC for RF generator control. Master control PLC directly controls all the subsystems except the Vacuum system and RF generator. The Vacuum system and RF generator have their own dedicated PLCs (S-7 300 and C-7 respectively). Further, these two PLC systems work as a slave for the Master control PLC system. Communication between PLC S-7 400, S-7 300 and central control room computer is done through Industrial Ethernet (IE). Control program and GUI are developed in Siemens Step-7 PLC programming software and Wincc SCADA software, respectively. There are approximately 150 analog and 200 digital control and monitoring signals required to perform complete closed loop control of the system. Since the source floats at high potential (˜35 kV); a combination of galvanic and fiber optic isolation has been implemented.

    Full Text Available Abstract. Nowadays, an integrated location, descriptive inventory data and geographical information are required for a better decision making in Indigenous community management activities. The management system can improve productivity and to save time, money and man power. Conventional maps and Indigenous inventories on papers or spread sheet are lack of meeting these requirements which are not static and subjected to change rapidly. The Geographic Information Systems (GIS and Database Management (DBM System are capabilities and confined in manipulation of location and descriptive data, respectively. A GIS system is chosen in Management Information and Infrastructure of Indigenous Communities because its meets all the requirements that can help the authorities to managed the community. GIS able to manipulate location and descriptive data as well as the relationships between them are dynamic. This paper will discussed briefly the conceptual design of GIS activities and Indigenous community in Royal Belum State Park, Malaysia, then terminology and theoretical concepts of GIS, Indigenous community management and the link between them are reviewed.Keywords:  Management, information, infrastructure, conceptual design, Indigenous community

    Science.gov (United States)

    Powietrzyńska, Małgorzata; Gangji, Al-Karim H.

    2016-08-01

    In this manuscript we bring to focus student perceptions of salience (or lack of thereof) of emotions in the undergraduate conceptual physics course (in the teacher education program) and their relevance to teaching and learning. Our analysis of student responses to the Mindfulness in Education Heuristic constitutes a feedback loop affording the teacher reflection over his instructional practices. Hence, we ponder pedagogical tools employed by the class instructor (second author) that students identify as evoking emotional responses (both positive and negative). Furthermore, we highlight this teacher's dispositions and his value system (axiology) that appear to bring to balance his passion for science (understood in a traditional Western way as a canon-based epistemology) and his approach to teaching that is driven by compassion towards his students many of whom perceive physics as challenging. We argue that adopting mindful disposition affords engaging in practices that assist in regulating emotions and attention that mediate learning of canonical science content. Likewise, we maintain that the instructor and his mindfulness-driven practices become a model to be replicated in his students' future careers. In such context, mindfulness may be perceived as part of what is referred to as a hidden curriculum. It is our position, however, that the science classroom is a site where wellness-promoting practices (such as mindfulness) should receive an overt attention by becoming science content to be learned and practiced by all citizens throughout everyday life thus contributing to its improved quality. In recognizing that such position may be challenging to adopt by science educators, we present the way the second author has been grappling with reframing his thinking around teaching science. We encourage educators to utilize heuristic methodology towards reflecting on and informing their practice and as one way of exposing their students to social constructs such as

    2016-02-01

    The construction of the PAX installation was inspired by the idea to make a beam of polarized antiprotons available for the experiments at the HESR FAIR. A spin filtering experiment with transversally polarized protons was realized using the new PAX installation at COSY. The results of this measurement are in perfect agreement with the FILTEX experiment. Hence, filtering is a viable method to produce a stored beam of polarized antiprotons. Another experiment which can be pursued using the PAX installation is the test of Time Reversal Invariance at COSY (TRIC). The goal of the TRIC experiment is to improve the present upper limit on violation of the T-odd P-even interaction by an order of magnitude using a genuine null observable available in a double polarized pd scattering. The status of the PAX spin filtering experiments as well as present understanding of the possible systematic uncertainties in TRIC are presented in this contribution.

    Simonsen, Lisa C.; Nealy, John E.; Townsend, Lawrence W.; Wilson, John W.

    The Langley cosmic ray transport code and the Langley nucleon transport code are used to quantify the transport and attenuation of galactic cosmic rays and solar proton flares through the Martian atmosphere. Surface doses are estimated using both a low-density and a high-density carbon dioxide model of the atmosphere which, in the vertical direction, provide a total of 16 g/sq cm and 22 g/sq cm of protection, respectively. At the Mars surface during the solar minimum cycle, a blood-forming organ (BFO) dose-equivalent of 10.5 to 12 rem/yr due to galactic cosmic ray transport and attenuation is calculated. Estimates of the BFO dose-equivalents which would have been incurred at the surface from three large solar flare events are also calculated. Doses are also estimated at altitudes up to 12 km above the Martian surface where the atmosphere will provide less total protection.

    The University of Texas at El Paso (UTEP) established the Pan American Center for Earth and Environmental Studies (PACES) in 1995 to conduct basic and applied research that contributes to NASA's Mission to Planet Earth. Specifically, PACES provides a repository of remote sensing and other information that supports investigations into an improved understanding of geological, ecological and environmental processes occurring in the southwestern United States and Northern Mexico. Approximately 85% of UTEP's students come from El Paso County, a fast growing urban region representative of many large cities in the Southwest that have, or will soon have, a majority of their population composed of groups currently underrepresented in the scientific and technical workforce. UTEP's student population has an ethnic distribution (63% Hispanic, 32% Anglo, 3% African American, 1.5 % Asian American, and less than 1% Native American) that closely matches the demographics of the region it serves. Thus, UTEP has a mission to serve a multicultural population where minority students comprise the majority. Most Hispanic students at UTEP are primarily of Mexican origin. A large number are first or second-generation U.S. citizens. Characteristics that unite Hispanic students, in particular those of Mexican-origin, are a strong sense of family loyalty and a belief that all family members are responsible for contributing to the economic stability and well-being of the family. Most of their families are larger in number than the national average, and a variety of generations live together or share considerable resources. Thus, many young people feel an obligation and a desire to go to work at a young age and to continue working while in college, thereby assisting their parents and other family members. Older siblings understand that they have responsibilities to do household chores, to aid their younger siblings economically, and to assist elderly family members. This "work ethic" within the

    2000-01-01

    This paper reviews ideas developed by the late Gordon Pask as part of this conversation theory (CT). CT uses theories of the dynamics of complex, self-organizing systems, in conjunction with models of conceptual structures, in order to give an account of conceptual coherence (for example, of a theory or a belief system) as a form of organizational closure. In Pask's own terms, CT is concerned both with the kinematics of knowledge structures and the kinetics of knowing and coming to know. The main features of modelling conceptual structures and processes used by Pask are presented. We continue by presenting a summary two-cycle model of learning, aimed to capture some of Pask's key insights with respect to conceptual coherence and the organizational closure of conceptual systems. Parallels are drawn with other work in epistemology, classic cybernetic studies of self-organization, and the concept of autopoiesis. The two-cycle model is then applied recursively to generate learning cycles and conceptual structures at different levels of abstraction, as a contribution to the work of Pask on the topology of thought. Finally, the model is applied reflexively. That is, its own form is considered as a topic for conversation and conceptualization. Carrying out such a reflection provides a coherent way of characterizing epistemological limits, while retaining a clear sense of there being an (in principle) unlimited praxeology of awareness.

    Full Text Available What is mathematics? The difficulty of having a precise, universal definition of mathematics has led prospective teachers to define the term in ways that make sense to them. This paper is part of a larger research project conducted in 2000 in an Ontarian university, Canada. The objectives were to identify and discuss conceptualizations of mathematics that prospective teachers brought to their preparation program and to explore the implications of such conceptualizations in terms of teaching and learning. It was believed that both the identification tools and understandings of prospective teachers’ conceptualizations of mathematics were significant for designing an effective pedagogy in accordance with mathematics reform-based perspectives. The research sample consisted of ten prospective teachers enrolled in a one-year bachelor of education program at an Ontarian university. The research used mathematics autobiographies of the respondents and semi-structured interviews of them as sources of data. Guided by the theory of personal construct for analysis of the data, the results showed that the respondents conceptualized mathematics in terms of metaphor, metonymy and combination of the two. The conclusion explores implications of such conceptualizations for mathematics teaching, learning and assessment.

  5. LEU silicide programs at Babcock and Wilcox

    International Nuclear Information System (INIS)

    The low enriched silicide development project at Babcock and Wilcox has matured into a production operation that has resulted in the completion of fuel elements for three research reactors; ORR, R-2 Studsvik and SAPHIR. Characteristic anomalies of silicide fuel which make the fabrication of fuel plates and elements more difficult than UAlx, have either been avoided, eliminated or significantly improved. One such anomaly is the reaction between uranium silicide fuel and aluminum matrix material. A detailed analysis was performed to characterize the extent of this reaction. Data suggests that a solid state diffusion of aluminum atoms into the uranium silicide lattice results in the formation of several intermediate Al-Si-U phases before forming a stable UAl4 phase

  6. Second annual report of the Environmental Restoration Monitoring and Assessment Program at Oak Ridge National Laboratory

    International Nuclear Information System (INIS)

    This report summarizes the salient features of the annual efforts of environmental monitoring and field investigations conducted to support the Environmental Restoration (ER) Program at the Oak Ridge National Laboratory (ORNL). This report focuses on the watershed scale, striving to provide an ORNL site-wide perspective on types, distribution, and transport of contamination. Results are used to enhance the conceptual understanding of the key contaminants and the sources, fluxes, and processes affecting their distribution and movement. This report summarizes the efforts of the Waste Area Grouping (WAG) 2 and Site Investigations (SI) program. WAG 2 is the lower portion of the White Oak Creek (WOC) system which drains the major contaminated sites at ORNL and discharges to the Clinch River where public access is allowed. The remedial investigation for WAG 2 includes a long-term multimedia environmental monitoring effort that takes advantage of WAG 2's role as an integrator and conduit of contaminants from the ORNL site. This report also includes information from other site-specific remedial investigations and feasibility studies (RI/FS) for contaminated sites at ORNL and data from other ongoing monitoring programs conducted by other organizations [e.g., the National Pollutant Discharge Elimination System (NPDES) compliance monitoring conducted by the Environmental Surveillance and Protection Section]. This information is included to provide an integrated basis to support ER decision making. This report summarizes information gathered through early 1993. Annual data, such as annual discharges of contaminants, are reported for calendar year 1992

  7. Implementing a risk management program at Falconbridge

    International Nuclear Information System (INIS)

    A corporate overview of Falconbridge was presented. Falconbridge, founded in 1928 is a leading producer of nickel, copper, cobalt and platinum group metals at low cost. A map displaying its worldwide locations was shown. In Canada, Falconbridge operates in Ontario and Nunavik Territory. The experience in Norway was briefly described, touching on market volatility, market intelligence, portfolio management, and risk management guidelines. The author then explained the purpose of the Energy Project Team, which was responsible for preparing for deregulation, developing strategies for purchasing energy, and minimizing the cost of purchased energy in a competitive market. The plan was described, and the emphasis placed on the core Ontario team. Communication played a large part. The management system functions were reviewed, and analysis provided. The financial integration model was presented. Risk management was dealt with, followed by market intelligence and operational hedge. Division impact was discussed. The major Falconbridge issues were: budget exposure to electricity price variability, how much fixed-price power supply and how long should the contracts be, regulatory structure, market purchase timing, and adhere to corporate risk management policy. The procurement process was described. The author concluded that the product must be kept simple and the number of products limited. A realistic schedule must by adhered to, and a short bidding period of four hours proved ideal. Supplier relationship must be consumer driven. The importance of communication plan was emphasized. Getting pre-approval to make the deal is important. tabs., figs

  8. Relativism: A conceptual analysis.

    Directory of Open Access Journals (Sweden)

    Vittorio Villa

    2010-01-01

    Full Text Available In this paper, first, I will try to give a conceptual definition of relativism, with the aim of singling out the basic elements common to the most relevant relativist conceptions. I will qualify as “relativistic” all conceptions in which all or a relevant part of its criteria and beliefs necessarily depend on a given context. Secondly, I will deal with some critical observations against relativism. From this point of view, a problem arises from the fact that many relativists would like to have the chance ofexpressing some objective judgments. Lastly, I will propose a relativistic conception: one that doesn’t incorporate absolutist elements at all and nevertheless could be able to explain the presence of a common core of criteria and beliefs in all our conceptual schemes and beliefs. Two distinctions are important here: first, local conceptual schemes and long term frameworks, and second, environment and world. This last distinction makes possible to speak, even inside a coherent relativist epistemological conception, of the existence of an objective reality.

  9. Cable condition monitoring program at Perry Nuclear power plant

    International Nuclear Information System (INIS)

    Degradation of polymeric materials, particularly cable insulation materials due to aging effects have long been a concern in the nuclear power industry. Industry qualification testing programs and research testing by the national laboratories have attempted to resolve this concern through design basis event tests preceded by simulated aging. As a final step ion resolving this concern through a systematic and disciplined technical program, Cleveland Electric Illuminating Co, (CEI) in 1983, initiated a long term in-situ, cable condition monitoring program at its Perry Nuclear Power Plant (PNPP). This paper provides a snap shot of this program as of today

  13. Safety orientations during ASTRID conceptual design phase

    International Nuclear Information System (INIS)

    In France, Safety Options Report is the first document issued in the frame of the licensing of any new nuclear facility. It is usually issued at the end of the conceptual design phase. For the ASTRID project, a Safety Orientations Document was first prepared during the pre-conceptual design phase. This document, transmitted to the French Safety Authority, aims at supporting the conceptual design studies, the associated R&D program and then, selecting the basic design safety options. ASTRID safety orientations are based on the previous Sodium-cooled Fast Reactors feedback, safety standards evolution, and other feedbacks such as the lessons issued from Fukushima accident. Safety goals set for ASTRID, considered as a demonstrator of future SFR, are ambitious, anticipating potential evolution of safety regulation. Among the safety orientations of ASTRID, the following items are developed in this paper: • Distinction between design domains which are: severe accident prevention, severe accident mitigation and practically eliminated situations, • Safety classification of equipment, • Identification of elements to be included into the “hard core” list, • Approach for severe accident, • Concept of “lines of mitigation”, • Demonstration of practical elimination of unacceptable situations.

  14. Reliability-centered maintenance program at Clinton Power Station

    International Nuclear Information System (INIS)

    Illinois Power Company is implementing a reliability-centered maintenance (RCM) program at its 984-MW(electric) Clinton Power Station (CPS). The RCM program as defined at CPS is broader and more encompassing than the classical RCM program that is now being introduced to the nuclear industry from the commercial airline industry. At CPS, all of the major elements of the classical RCM approach are being used, but in conjunction with other reliability engineering techniques (e.g., traditional system analysis, review of CPS-specific and industry operating experience). The following are the fundamental objectives of the CPS RCM program: (1) ensure safe and reliable operation of CPS; (2) maintain equipment at inherent levels of safety and reliability and restore these whenever they become degraded; (3) develop design improvements when inherent equipment reliability is inadequate; and (4) accomplish the above objectives at a minimum of total cost, including maintenance costs and the costs of residual failures

  15. Brief communication: Reaction to fire by savanna chimpanzees (Pan troglodytes verus) at Fongoli, Senegal: Conceptualization of "fire behavior" and the case for a chimpanzee model.

    Pruetz, Jill D; LaDuke, Thomas C

    2010-04-01

    The use and control of fire are uniquely human traits thought to have come about fairly late in the evolution of our lineage, and they are hypothesized to correlate with an increase in intellectual complexity. Given the relatively sophisticated cognitive abilities yet small brain size of living apes compared to humans and even early hominins, observations of wild chimpanzees' reactions to naturally occurring fire can help inform hypotheses about the likely responses of early hominins to fire. We use data on the behavior of savanna chimpanzees (Pan troglodytes verus) at Fongoli, Senegal during two encounters with wildfires to illuminate the similarities between great apes and humans regarding their reaction to fire. Chimpanzees' close relatedness to our lineage makes them phylogenetically relevant to the study of hominid evolution, and the open, hot and dry environment at Fongoli, similar to the savanna mosaic thought to characterize much of hominid evolution, makes these apes ecologically important as a living primate model as well. Chimpanzees at Fongoli calmly monitor wildfires and change their behavior in anticipation of the fire's movement. The ability to conceptualize the "behavior" of fire may be a synapomorphic trait characterizing the human-chimpanzee clade. If the cognitive underpinnings of fire conceptualization are a primitive hominid trait, hypotheses concerning the origins of the control and use of fire may need revision. We argue that our findings exemplify the importance of using living chimpanzees as models for better understanding human evolution despite recently published suggestions to the contrary.

  17. INEEL Subregional Conceptual Model Report Volume 2: Summary of Existing Knowledge of Geochemical Influences on the Fate and Transport of Contaminants in the Subsurface at the INEEL

    Energy Technology Data Exchange (ETDEWEB)

    Paul L. Wichlacz; Robert C. Starr; Brennon Orr

    2003-09-01

    This document summarizes previous descriptions of geochemical system conceptual models for the vadose zone and groundwater zone (aquifer) beneath the Idaho National Engineering and Environmental Laboratory (INEEL). The primary focus is on groundwater because contaminants derived from wastes disposed at INEEL are present in groundwater, groundwater provides a pathway for potential migration to receptors, and because geochemical characteristics in and processes in the aquifer can substantially affect the movement, attenuation, and toxicity of contaminants. The secondary emphasis is perched water bodies in the vadose zone. Perched water eventually reaches the regional groundwater system, and thus processes that affect contaminants in the perched water bodies are important relative to the migration of contaminants into groundwater. Similarly, processes that affect solutes during transport from nearsurface disposal facilities downward through the vadose zone to the aquifer are relevant. Sediments in the vadose zone can affect both water and solute transport by restricting the downward migration of water sufficiently that a perched water body forms, and by retarding solute migration via ion exchange. Geochemical conceptual models have been prepared by a variety of researchers for different purposes. They have been published in documents prepared by INEEL contractors, the United States Geological Survey (USGS), academic researchers, and others. The documents themselves are INEEL and USGS reports, and articles in technical journals. The documents reviewed were selected from citation lists generated by searching the INEEL Technical Library, the INEEL Environmental Restoration Optical Imaging System, and the ISI Web of Science databases. The citation lists were generated using the keywords ground water, groundwater, chemistry, geochemistry, contaminant, INEL, INEEL, and Idaho. In addition, a list of USGS documents that pertain to the INEEL was obtained and manually searched

  18. Successful Minority PhD Producing Programs -- Bell Laboratories and the Meyerhoff Scholarship Program at UMBC

    Science.gov (United States)

    Johnson, Anthony

    2009-03-01

    The Bell Labs Cooperative Research Fellowship Program for Minorities (CRFP), founded in 1972 was one of the first programs of its kind in the US to address the issue of under-representation of minorities in the fields of engineering, mathematics and science. As of 2000, well over 100 PhDs graduated with CRFP sponsorship and a significant fraction joined the research ranks of Bell Labs. In the early days of the program as much as 50% of African American PhDs in Physics in the US were granted to students supported by CRFP. Another unique program initiated by Bell Labs in 1974 that introduced undergraduate students to cutting edge research was the Summer Research Program for Minorities and Women (SRP). The SRP served as a natural feeder to the CRFP. Personally, my career in Optical Physics owes its foundation to these programs and I will give my perspective on participation and impact of the Bell Labs SRP (1974) and CRFP (1975) programs. The Meyerhoff Scholars Program at UMBC was developed in 1988. At that time, UMBC was graduating fewer than 18 African-American STEM majors per year. In 1996 the program was opened to all students with an interest in the advancement of minorities in STEM fields. The program enjoys an overall 18-year retention rate of greater than 95% and has over 500 graduates since 1993. As of May 2006, 75% of these graduates are enrolled in graduate and/or professional programs, with 49 PhDs and 20 MD/PhDs completed as of August 2006. The program challenges notions about minority achievement. Meyerhoff Scholars have changed the perceptions of those around them -- the expectations of faculty who instruct them, the attitudes of students who learn beside them, and the perspectives of scientists who engage them in research.

  19. Global products or customization to different countries: Conceptual framework and application at Wahler, A german company Of the automotive sector

    Ailton Conde Jussani

    2013-12-01

    Full Text Available Competition in global markets demands product strategies that can help firms deal with the dilemma of global products versus customization, in serving the markets of different countries. Global products lead to large scales, automation, lower costs, plus the easy transfer of people and technology among many subsidiaries, as well as between corporate headquarters and the subsidiaries. However, the lack of customization makes it difficult to gain share in countless market segments, in many countries, and it may even stop a firm from entering in certain countries. This study outlines a model designed to facilitate this type of decision-making. First, based on the literature, a conceptual model was drawn up and the decision-related elements were grouped into seven factors that aid product customization decisions: 1. Market Positioning; 2. Customers’ strategic importance; 3. Product life-cycle development; 4. Legal requirements; 5. Physical environment; 6. Infrastructure and compatibility; and 7. Suppliers’ strategic importance. The case method was used, given the complex nature of the problem, which calls for an in-depth analysis. The model was tested on one of the products made a German company with a Brazilian subsidiary. The components of the valve and the technological trends were analyzed. The case study showed that the influencing factors are interrelated. It became clear that the technological component is directly related with the seven decision factors, and this aspect is analyzed in depth. Nevertheless, further studies are necessary to validate the model, since the case method does not allow one to generalize the findings.

  20. Integrated environmental monitoring program at the Hanford Site

    International Nuclear Information System (INIS)

    The US Department of Energy's Hanford Site, north of Richland, Washington, has a mission of defense production, waste management, environmental restoration, advanced reactor design, and research development. Environmental programs at Hanford are conducted by Pacific Northwest Laboratory (PNL) and the Westinghouse Hanford Company (WHC). The WHC environmental programs include the compliance and surveillance activities associated with site operations and waste management. The PNL environmental programs address the site-wide and the of-site areas. They include the environmental surveillance and the associated support activities, such as dose calculations, and also the monitoring of environmental conditions to comply with federal and state environmental regulations on wildlife and cultural resources. These are called ''independent environmental programs'' in that they are conducted completely separate from site operations. The Environmental Surveillance and Oversight Program consists of the following projects: surface environmental surveillance; ground-water surveillance; wildlife resources monitoring; cultural resources; dose overview; radiation standards and calibrations; meteorological and climatological services; emergency preparedness

    Full Text Available This study investigated the service Physical Education Program at Batangas State University system based on the assessments of the administrators, faculty and students on its implementation in consideration of its program components and attitudes of PE teachers towards the subject with the proposed revitalized Physical Education program as an output. Using descriptive research design of research and statistical tools such as percentage, weighted mean, and f-test, the result showed a great extent of the implementation of the service Physical Education program at BSU system in terms of attainment of objectives, curriculum, teaching effectiveness of faculty, and adequacy of facilities, equipment, supplies, and instructional materials. Positive attitudes towards PE except on the concerns on reducing the time allocation for the subject and that it should be mainly sports and play were among the findings. In addition, the objectives of the PE program are believed to be the best indicators while the least indicator is the facilities, equipment and supplies.

    2013-03-01

    As part of the broader SPIN-UP Regional Workshops program, the American Association of Physics Teachers organized two workshops directed at specific audiences. In May 2011, Hampton University hosted a SPIN-UP workshop focusing on physics programs at Historically Black Colleges and Universities. In May 2012, the University of Texas at Austin hosted a workshop focusing on physics programs in Texas, many of which were affected by a decision of the Texas Higher Education Coordinating Board to eliminate degree programs (in all fields) that produced fewer than five majors per year averaged over the most recent three-year period. We will summarize the discussions at these meetings and what is being done to respond to the challenges faced by the physics departments attending the workshops.

    2011-12-01

    With funding from an NSF Informal Science Education grant, the Pacific Science Center in Seattle, Washington began the Science Communication Fellowship program in 2009 as part of the Portal to the Public initiative. The purpose of the Science Communication Fellowship program is to train scientists and engineers to communicate more effectively with the general public regarding their research and to assist with the development of hands-on activities that can be used by the scientists and engineers for outreach activities. The program came out of a collaboration to develop a model for effectively communicating current science research at informal science education organizations. The program model has undergone in-depth research and evaluation to assess its effectiveness and impact. To become Science Communication Fellows, researchers participate in four three-hour professional development sessions, where they learn communication techniques through role-playing and hands-on activities. The workshops are supplemented with additional one-on-one meetings with Science Center staff to help the new Fellows develop activities for use at outreach events. These activities are then used by the Fellows at public events that highlight current research taking place in the region. To date over 80 scientists and engineers have gone through the training sessions to become Science Communication Fellows. The Pacific Science Center holds approximately 12 events a year in which Fellows can facilitate their activity. Public programs range from small, monthly programs to large, annual Research Weekends. Funding for this program continues through support from NIH, IMLS, NSF, and NASA grants. For more information, please contact the current program administrator Dana Vukajlovich at DVukajlovich@pacsci.org.

    2001-09-30

    The objective of the ATS program is to develop ultra-high efficiency, environmentally superior and cost competitive gas turbine systems for base load application in utility, independent power producer and industrial markets. Specific performance targets have been set using natural gas as the primary fuel: (1) System efficiency that will exceed 60% (lower heating value basis) on natural gas for large scale utility turbine systems; for industrial applications, systems that will result in a 15% improvement in heat rate compared to currently available gas turbine systems. (2) An environmentally superior system that will not require the use of post combustion emissions controls under full load operating conditions. (3) Busbar energy costs that are 10% less than current state-of-the-art turbine systems, while meeting the same environmental requirements. (4) Fuel-flexible designs that will operate on natural gas but are capable of being adapted to operate on coal-derived or biomass fuels. (5) Reliability-Availability-Maintainability (RAM) that is equivalent to the current turbine systems. (6) Water consumption minimized to levels consistent with cost and efficiency goals. (7) Commercial systems that will enter the market in the year 2000. In Phase I of the ATS program, Siemens Westinghouse found that efficiency significantly increases when the traditional combined-cycle power plant is reconfigured with closed-loop steam cooling of the hot gas path. Phase II activities involved the development of a 318MW natural gas fired turbine conceptual design with the flexibility to burn coal-derived and biomass fuels. Phases I and II of the ATS program have been completed. Phase III, the current phase, completes the research and development activities and develops hardware specifications from the Phase II conceptual design. This report summarizes Phase III Extension activities for a three month period. Additional details may be found in monthly technical progress reports covering the

    2016-06-01

    The `conceptual storyline' of a lesson refers to the flow and sequencing of learning activities such that science concepts align and progress in ways that are instructionally meaningful to student learning of the concepts. Research demonstrates that when teachers apply lesson design strategies to create a coherent science content storyline, student learning is positively impacted (Roth et al., 2011). Because the conceptual storyline is often implicit within a lesson, and teachers often have difficulty articulating this aspect of lesson design (Lo et al., 2014), our professional development program engages elementary teachers in analyzing and developing graphic representations of a lesson's conceptual storyline to make that element explicit. In this exploratory study, we present typologies that represent two primary challenges teachers faced in developing coherent conceptual storylines in their lesson design, and examine the extent to which professional development enhanced their capacity to develop a coherent conceptual storyline.

    The `conceptual storyline' of a lesson refers to the flow and sequencing of learning activities such that science concepts align and progress in ways that are instructionally meaningful to student learning of the concepts. Research demonstrates that when teachers apply lesson design strategies to create a coherent science content storyline, student learning is positively impacted (Roth et al., 2011). Because the conceptual storyline is often implicit within a lesson, and teachers often have difficulty articulating this aspect of lesson design (Lo et al., 2014), our professional development program engages elementary teachers in analyzing and developing graphic representations of a lesson's conceptual storyline to make that element explicit. In this exploratory study, we present typologies that represent two primary challenges teachers faced in developing coherent conceptual storylines in their lesson design, and examine the extent to which professional development enhanced their capacity to develop a coherent conceptual storyline.

  15. Conceptual Design Report Cask Loadout Sys and Cask Drop Redesign for the Immersion Pail Support Structure and Operator Interface Platform at 105 K West

    Energy Technology Data Exchange (ETDEWEB)

    LANGEVIN, A.S.

    1999-07-12

    This conceptual design report documents the redesign of the IPSS and the OIP in the 105 KW Basin south loadout pit due to a postulated cask drop accident, as part of Project A.5/A.6, Canister Transfer Facility Modifications. Project A.5/A.6 involves facility modifications needed to transfer fuel from the basin into the cask-MCO. The function of the IPSS is to suspend, guide, and position the immersion pail. The immersion pail protects the cask-MCO from contamination by basin water and acts as a lifting device for the cask-MCO. The OIP provides operator access to the south loadout pit. Previous analyses studied the effects of a cask-MCO drop on the south loadout pit concrete structure and on the IPSS. The most recent analysis considered the resulting loads at the pit slab/wall joint (Kanjilal, 1999). This area had not been modeled previously, and the analysis results indicate that the demand capacity exceeds the allowable at the slab/wall joint. The energy induced on the south loadout pit must be limited such that the safety class function of the basin is maintained. The solution presented in this CDR redesigns the IPSS and the OIP to include impact-absorbing features that will reduce the induced energy. The impact absorbing features of the new design include: Impact-absorbing material at the IPSS base and at the upper portion of the IPSS legs. A sleeve which provides a hydraulic means of absorbing energy. Designing the OIP to act as an impact absorber. The existing IPSS structure in 105 KW will be removed. This conceptual design considers only loads resulting from drops directly over the IPSS and south loadout pit area. Drops in other areas of the basin are not considered, and will be covered as part of a future revision to this CDR.

  16. The quality assurance program at K ampersand S

    International Nuclear Information System (INIS)

    K ampersand S operates the largest and one of the most comprehensive Accredited Dosimetry Calibration Laboratories (ADCLs) in the American Association of Physicists in Medicine (AAPM) secondary laboratory system. It offers calibrations covering energies from Grenz-Ray (0.03-mm Al) to cesium-137 and cobalt-60, brachytherapy source and well chamber calibrations for low-activity sources, and, recently, high-dose-rate iridium-192. The present Quality Assurance (QA) program at K ampersand S began with the AAPM Guidelines for Accreditation (Task Group No. 22 and No. 3, 1989) and grew over the past 10 years to include all aspects of providing a private, self-supporting calibration service from a free-standing independent facility. Some aspects of the QA program were prompted by the requirements of the nuclear power industry while other parts were from national consensus standards or the experiences of staff. Redundancy and teamwork are the most important characteristics of this QA program. K ampersand S has participated in a National Institute of Standards and Technology (NIST) measurement quality assurance (MQA) program since 1982, and, in recent years, an ADCL intralaboratory intercomparison was conducted by Task Group 3 of the Radiation Therapy Committee of the AAPM. One measure of the credibility of a QA program is consistent performance on the MQA program and the ADCL intercomparisons over the past 10 years. An equally important measure of the ability of a program to assure quality results is the frequency of reported errors

    2009-08-01

    A new Radiochemistry Education and Research Program was started at the Pennsylvania University, Radiation Science and Engineering Center. The program was initially supported by the Department of Energy, Radiochemistry Education Award Program (REAP). Using REAP funding as leverage we obtained support from the Los Alamos National Laboratory, Department of Homeland Security, Domestic Nuclear Detection Office, various internal funding from PSU and other entities. The PSU radiochemistry program primarily addresses radiochemistry education and secondarily nuclear and radiochemistry research. The education program consists of bolstering our existing radiochemistry and related courses; Nuclear and Radiochemistry, Radiation Detection and Measurement, Radiological Safety and developing new courses, e.g., Laboratory Experiments in Applied Nuclear and Radiochemistry, and Nuclear Methods in Science. A new laboratory has been created with state of the art equipment for the Laboratory Experiments in Applied Nuclear and Radiochemistry course. We also plan to revitalize the nuclear and radiochemistry research programs. We established a state-of-the-art Neutron Activation Analysis Laboratory and a gamma ray spectroscopy laboratory that has 10 stations including state-of-the-art nuclear spectroscopy hardware and software. In addition, we embarked on an expansion plan that included building a new neutron beam hall and neutron beam ports with a cold neutron source. One of the reasons to have a cold neutron source is for the development of a prompt gamma activation analysis facility. A detailed description of PSU radiochemistry education and research program will be given and the future plans will be discussed.

  18. USING LOGIC COMPONENTS FOR CONCEPTUAL DIE DESIGN

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Logic components are used to support the conceptual design. Taking the stamping die structure as the research object,several logic components are defined for the conceptual die construction design. A new method-logic assembly modeling is presented to satisfy the characteristic of the top-down die design process. Representing shapes and spatial relations in logic can provide a natural,intuitive method of developing complete computer systems for reasoning about die construction design at the conceptual stage. This method can reflect the designer's thought clearly and provide the designer with a test bed for generating alternatives and performing reasoning work at the conceptual die design stage.

    Science.gov (United States)

    Hughes, Chris

    2008-03-01

    Over the past decade a core group of faculty at James Madison University has created an interdisciplinary program in materials science that provides our students with unique courses and research experiences that augment the existing, high-quality majors in physics and astronomy, chemistry and biochemistry, geology and environmental science, mathematics and statistics, and integrated science and technology. The university started this program by creating a Center for Materials Science whose budget is directly allocated by the provost. This source of funds acts as seed money for research, support for students, and a motivating factor for each of the academic units to support the participation of their faculty in the program. Courses were created at the introductory and intermediate level that are cross-listed by the departments to encourage students to enroll in them as electives toward their majors. Furthermore, the students are encouraged to participate in undergraduate research in materials since this is the most fundamental unifying theme across the disciplines. This talk will cover some of the curricular innovations that went into the design of the program to make it successful, examples of faculty and student research and how that feeds back into the classroom, and success stories of the interactions that have developed between departments because of this program. Student outcomes and future plans to improve the program will also be discussed.

    This paper reports the building of a conceptual profile of ‘life’. We took as a starting point the hypothesis that the concept of life is polysemous, showing several possible meanings, and, thus, admitting a conceptual profile. We attempted to demarcate the zones that constitute this conceptual profile through a dialogic interplay between theoretical and empirical studies, involving at least three genetic domains: the sociocultural domain, by means of a review about the concept of life and it...

  2. Waste Tank Corrosion Program at Savannah River Site

    International Nuclear Information System (INIS)

    The Savannah River Site (SRS) has approximately 30 million gallons of high level radioactive waste stored in 51 underground tanks. SRS has maintained an active corrosion research and corrosion control and monitoring program throughout the operating history of SRS nuclear waste storage tanks. This program is largely responsible for the successful waste storage experience at SRS. The program has consisted of extensive monitoring of the tanks and surrounding environment for evidence of leaks, extensive research to understand the potential corrosion processes, and development and implementation of corrosion chemistry control. Current issues associated with waste tank corrosion are primarily focused on waste processing operations and are being addressed by a number of active programs and initiatives

  3. The duty health physicist program at Byron Nuclear Power Station

    International Nuclear Information System (INIS)

    The Duty Health Physicist Program at Byron Station was established to deal with routine health physics tasks and provide an interface between frontline and upper radiation-chemistry management. The program consists of a weekly rotation of selected members of the health physics staff into the duty health physicist position to handle the assigned duty tasks. The tasks include, but are not limited to, daily isotopic and air sample review, effluent release package review, maximum permissible concentration calculations, dose approvals, as-low-as-reasonably-achievable action review of pending jobs, and general availability to answer questions and address problems in health-physics-related areas of plant operation. The daily attendance of the duty health physicist at the radiation-chemistry and station plan-of-the-day meetings has increased the overall presence and visibility of the health physics program to upper station management and other station departments. Since its inception in July of 1985, the Duty Health Physics Program has been a major contributor to the observed 50% reduction in reportable personnel errors in the radiation-chemistry department (based on personnel-error-related deviation reports and license event reports generated on the radiation-chemistry department at Byron Station). Although difficulty to quantify, other important benefits of this program are also discussed in this paper

    1995-10-01

    In response to the industrial and utility objectives specified for the ATS, the GE Power Generation ATS Phase 2 Program consisted of a dual approach. These were (1) development of an Industrial ATS (aircraft engine based) led by GE Aircraft Engines, and (2) development of a Utility ATS which was already underway at GEPG. Both programs required the identification and resolution of critical technical issues. Both systems were studied in Tasks 3-7, and both have resulted in designs that meet all ATS goals. The Industrial ATS as defined (130 MW) did not meet projected market power size requirements, and emphasis has remained on the Utility ATS development. The design and testing effort has been focused on the MS7001H combined cycle gas turbine, as the next product evolution in GE Power Generation`s product line. Common technology derived from the ATS Program is also being incorporated into the 50 Hz version of the ATS utility machine designated as the MS9001H.

  5. Analysis of the TREAT LEU Conceptual Design

    International Nuclear Information System (INIS)

    Analyses were performed to evaluate the performance of the low enriched uranium (LEU) conceptual design fuel for the conversion of the Transient Reactor Test Facility (TREAT) from its current highly enriched uranium (HEU) fuel. TREAT is an experimental nuclear reactor designed to produce high neutron flux transients for the testing of reactor fuels and other materials. TREAT is currently in non-operational standby, but is being restarted under the U.S. Department of Energy's Resumption of Transient Testing Program. The conversion of TREAT is being pursued in keeping with the mission of the Department of Energy National Nuclear Security Administration's Material Management and Minimization (M3) Reactor Conversion Program. The focus of this study was to demonstrate that the converted LEU core is capable of maintaining the performance of the existing HEU core, while continuing to operate safely. Neutronic and thermal hydraulic simulations have been performed to evaluate the performance of the LEU conceptual-design core under both steady-state and transient conditions, for both normal operation and reactivity insertion accident scenarios. In addition, ancillary safety analyses which were performed for previous LEU design concepts have been reviewed and updated as-needed, in order to evaluate if the converted LEU core will function safely with all existing facility systems. Simulations were also performed to evaluate the detailed behavior of the UO2-graphite fuel, to support future fuel manufacturing decisions regarding particle size specifications. The results of these analyses will be used in conjunction with work being performed at Idaho National Laboratory and Los Alamos National Laboratory, in order to develop the Conceptual Design Report project deliverable.

    We propose applying the categorical compositional scheme of [6] to conceptual space models of cognition. In order to do this we introduce the category of convex relations as a new setting for categorical compositional semantics, emphasizing the convex structure important to conceptual space applications. We show how conceptual spaces for composite types such as adjectives and verbs can be constructed. We illustrate this new model on detailed examples.

  12. Combined Estimation of Hydrogeologic Conceptual Model, Parameter, and Scenario Uncertainty with Application to Uranium Transport at the Hanford Site 300 Area

    Energy Technology Data Exchange (ETDEWEB)

    Meyer, Philip D.; Ye, Ming; Rockhold, Mark L.; Neuman, Shlomo P.; Cantrell, Kirk J.

    2007-07-30

    This report to the Nuclear Regulatory Commission (NRC) describes the development and application of a methodology to systematically and quantitatively assess predictive uncertainty in groundwater flow and transport modeling that considers the combined impact of hydrogeologic uncertainties associated with the conceptual-mathematical basis of a model, model parameters, and the scenario to which the model is applied. The methodology is based on a n extension of a Maximum Likelihood implementation of Bayesian Model Averaging. Model uncertainty is represented by postulating a discrete set of alternative conceptual models for a site with associated prior model probabilities that reflect a belief about the relative plausibility of each model based on its apparent consistency with available knowledge and data. Posterior model probabilities are computed and parameter uncertainty is estimated by calibrating each model to observed system behavior; prior parameter estimates are optionally included. Scenario uncertainty is represented as a discrete set of alternative future conditions affecting boundary conditions, source/sink terms, or other aspects of the models, with associated prior scenario probabilities. A joint assessment of uncertainty results from combining model predictions computed under each scenario using as weight the posterior model and prior scenario probabilities. The uncertainty methodology was applied to modeling of groundwater flow and uranium transport at the Hanford Site 300 Area. Eight alternative models representing uncertainty in the hydrogeologic and geochemical properties as well as the temporal variability were considered. Two scenarios represent alternative future behavior of the Columbia River adjacent to the site were considered. The scenario alternatives were implemented in the models through the boundary conditions. Results demonstrate the feasibility of applying a comprehensive uncertainty assessment to large-scale, detailed groundwater flow

    Full Text Available CONCEPTUAL DELIMITATIONS OF CONTROLLING Nedelcu Serban Universitatea ,,Babes-Bolyai`` Facultatea de Stiinte Economice si Gestiunea Afacerilor 'Controlling' represents a new concept in the Romanian economic environement, being implemented successfully in very few companies. Unlike the German space where controlling is very well represented both at a practical level and in the academia, in Romania controlling can only be found at a practical level, and the specialized literature is restraint, almost absent. Since the practicians of controlling in Romania only know the toolkit they use and not the theoretical elements as well, what is needed in this case is a conceptual delimitation so that controlling would be better implemented, and improved with various elements of the economic environment. In practice, inside various linguistic areas different problems of communication may occur very often in regards to the use of different concepts that may be missunderstood. Therefore in the Romanian research area it becomes imperative to try and clarify the existing issues and to intensify the reasearch in this field. Studying the evolution of the concept we observe that the need for its implementation is primarily experienced at the practical level of the companies, to be then followed by a debate in the specialized literature. The internationalization and the fierce competition that the Romanian companies are confronting on the ecenomic market represent the decissive factor in adopting the concept of controlling.This article is part of the research conducted for my doctoral thesis, 'Controlling in hetergenous economic envirnoments', under the coordination and supervision of Prof.Dr.Dumitru Matis.

Recently, as part of the NRU Licenseability Extension (LE) program, AECL has developed a Plant Life Management (PLiM) program to support planned operation to at least 2012. The objective of the PLiM program is to systematically assess the various aging related degradation mechanisms in order to evaluate both current condition and the potential for further extending service life. Another objective is to identify the associated maintenance, surveillance and inspection strategy for service life extension of important Structures, Systems, and Components (SSCs). The strategy uses approaches that build on AECL's PLiM/PLEx experience at CANDU plants, but also utilizes previous Age Management and refurbishment work performed at NRU. The program is multi-faceted, systematic and integrated, and involves the facility operations organization in the assessment process. The PLiM program has used a number of pilot studies in the initial stages to test out PLiM procedures, gain experience with the various aging assessment techniques and enhance effectiveness of interfaces between the aging assessment team and the facility staff. The aging assessment process begins with the screening and prioritization of the facility SSCs. Selection of the appropriate assessment technique is based on priority and component type. Life and condition assessment techniques used at other plants have been adapted to NRU and performed on important components and structures. For important systems, a combination of condition assessment and systematic maintenance assessment techniques are being used. Detailed PLiM procedures have been developed and are in trial use in pilot studies. These procedures are currently being updated with the experience gained during the pilot studies. In

    Bilheux, Hassina; Herwig, Ken; Keener, Scott; Davis, Larry

    VENUS (Versatile Neutron Imaging Beam line at the Spallation Neutron Source) will be a world-class neutron-imaging instrument that will uniquely utilize the Spallation Neutron Source (SNS) time-of-flight (TOF) capabilities to measure and characterize objects across several length scales (mm to μm). When completed, VENUS will provide academia, industry and government laboratories with the opportunity to advance scientific research in areas such as energy, materials, additive manufacturing, geosciences, transportation, engineering, plant physiology, biology, etc. It is anticipated that a good portion of the VENUS user community will have a strong engineering/industrial research focus. Installed at Beam line 10 (BL10), VENUS will be a 25-m neutron imaging facility with the capability to fully illuminate (i.e., umbra illumination) a 20 cm x 20 cm detector area. The design allows for a 28 cm x 28 cm field of view when using the penumbra to 80% of the full illumination flux. A sample position at 20 m will be implemented for magnification measurements. The optical components are comprised of a series of selected apertures, T0 and bandwidth choppers, beam scrapers, a fast shutter to limit sample activation, and flight tubes filled with Helium. Techniques such as energy selective, Bragg edge and epithermal imaging will be available at VENUS.

    GE has achieved a leadership position in the worldwide gas turbine industry in both industrial/utility markets and in aircraft engines. This design and manufacturing base plus our close contact with the users provides the technology for creation of the next generation advanced power generation systems for both the industrial and utility industries. GE has been active in the definition of advanced turbine systems for several years. These systems will leverage the technology from the latest developments in the entire GE gas turbine product line. These products will be USA based in engineering and manufacturing and are marketed through the GE Industrial and Power Systems. Achieving the advanced turbine system goals of 60% efficiency, 8 ppmvd NOx and 10% electric power cost reduction imposes competing characteristics on the gas turbine system. Two basic technical issues arise from this. The turbine inlet temperature of the gas turbine must increase to achieve both efficiency and cost goals. However, higher temperatures move in the direction of increased NOx emission. Improved coating and materials technologies along with creative combustor design can result in solutions to achieve the ultimate goal.

    The Eastern Washington Section of the American Nuclear Society (ANS) has tried a number of different approaches to reach out to the local communities and to work alongside educators to increase their awareness of nuclear technology. Some of the programs that the authors have started may serve as examples for other sections in their outreach activities. The Eastern Washington Section of the ANS has an education committee coordinator who is assigned the task of working with high school and college students to increase the awareness of nuclear energy. The most effective approach that the authors have found to reach out to the area schools is to get directly involved with community activities that already interface with the schools and get to know the science teachers at the local schools. The Hanford project has a student internship program called ``Inquiry into Science``. The program allows students to work at Hanford for Science credits. Another program that the local section sponsors is grants to high schools to promote the awareness of nuclear technology. The local section has also worked alongside local community groups to increase nuclear science education. For years the authors have been active in the local science fair, providing awards to nuclear-related science projects. Other community events that the ANS has been involved in include the US Department of Energy Knowledge Bowl and National Engineers.

    Observatories and other science research organizations want to share their research and activities with the public. The last several years, social media has become and increasingly important venue for communicating information about observatory activities, research and education and public outreach.The National Optical Astronomy Observatory (NOAO) uses a wide variety of social media to communicate with different audiences. NOAO is active on social media platforms including Facebook, Twitter, Google+ and Pinterest. Our social media accounts include those for the National Optical Astronomy Observatory, Cerro Tololo Inter-American Observatory, Kitt Peak National Observatory and our dark skies conservation program Globe at Night.Our social media programs have a variety of audiences. NOAO uses social media to announce and promote NOAO sponsored meetings, observatory news and proposal deadlines to the professional astronomical community. Social media accounts are used to disseminate NOAO press releases, images from the observatory and other science using data from NOAO telescopes.Social media is important in our Education and Public Outreach programs (EPO). Globe at Night has very active facebook and twitter accounts encouraging people to become involved in preserving dark skies. Social media plays a role in recruiting teachers for professional development workshops such as Project Astro.NOAO produces monthly podcasts for the 365 Days of Astronomy podcast featuring interviews with NOAO astronomers. Each podcast highlights the science of an NOAO astronomer, an NOAO operated telescope or instrument, or an NOAO program. A separate series of podcasts is produced for NOAO’s Dark Skies Education programs. All the podcasts are archived at 365daysofastronomy.org.

    International Nuclear Information System (INIS)

    Highlights: • A setup to perform In-Gas Laser Ionization and Spectroscopy experiments at the Super Separator Spectrometer is presented. • The reported studies address important aspects necessary to applied the IGLIS technique to short-lived isotopes. • An R and D phase required to reach an enhanced spectral resolution will be carried out at KU Leuven. • High-sensitivity and enhanced-resolution laser spectroscopy studies will be possible with the IGLIS setup at S3. -- Abstract: The results of preparatory experiments and the preliminary designs of a new in-gas laser ionization and spectroscopy setup, to be coupled to the Super Separator Spectrometer S3 of SPIRAL2-GANIL, are reported. Special attention is given to the development and tests to carry out a full implementation of the in-gas jet laser spectroscopy technique. Application of this novel technique to radioactive species will allow high-sensitivity and enhanced-resolution laser spectroscopy studies of ground- and excited-state properties of exotic nuclei

  16. Qualified nuclear engineer certification program at Commonwealth Edison

    International Nuclear Information System (INIS)

    Commonwealth Edison (CECo) has utilized a nuclear engineer training and certification program called the Qualified Nuclear Engineer (QNE) Program for many years to ensure that on-site nuclear engineers are ready to assume critical responsibilities in support of reactor operations and reactivity management. Review of this program is significant now because it effectively implements and exceeds the guidance provided by the Institute of Nuclear Power Operations in ACAD 91-017, open-quotes Guidelines for Training and Qualification of Engineering Support Personnelclose quotes for position-specific training of reactor engineers. The CECo QNE program was initiated for boiling water reactor (BWR) station nuclear engineers after reactivity management events occurred in the early 1970s. In 1974 and 1975, two major fuel-failure events occurred in CECo BWR cores caused, in part, by control rod manipulations inappropriate for the original 7 x 7 fuel, which was very susceptible to pellet-clad interaction. In the 1980s pressurized water reactor (PWR) stations across the nation also had a significant number of reactivity management events. From these events, it was apparent that PWR as well as BWR nuclear engineers needed more specialized training to protect the fuel and a PWR QNE program was implemented at CECo. The major purpose of the QNE program is to provide engineers with the proper training and experience to enable them to make good decisions and recommendations regarding core reactivity and fuel performance. The duties that a QNE can be expected to perform after certification include (a) providing reactivity management guidance to operations personnel during normal and abnormal conditions and (b) reviewing special tests, procedures, and modifications that affect reactivity management

    1994-05-01

    The Lake Afton Public Observatory was founded 14 years ago as a joint project of the city, county, local schools, and Wichita State University to provide educational programs for the public and school children. A staff of 4 professional astronomers presents daytime and evening programs at the Observatory and makes presentations in schools to over 20,000 people per year. Programs are scheduled 6 days a week during the academic year and 3 days a week in the summer. Our public programs deviate significantly from the traditional observatory open house by following a specific theme. Selection and discussion of each object is centered on that theme. For example, a program on The Life Story of a Star would view a diffuse nebula (to discuss star formation), a young star cluster (to discuss one outcome of star formation), a double star (to discuss how the properties of stars are determined), and a planetary nebula (to discuss the death of a star). To complement the observing experiences of our visitors, we have developed a wide range of interactive exhibits to develop the concepts touched on in the viewing programs. We have also developed exhibit lending kits for extended use in school classrooms, educational games, activity manuals for teachers, and short videos to introduce single concepts in the classroom. In the past year we have begun to offer a series of workshops for in-service teachers to expand their knowledge of astronomy and to provide them with additional resources for teaching astronomy. This work is supported in part by NSF EPSCoR grant OSR-9255223.

  18. DUSEL-related Science at LBNL Program and Opportunities

    International Nuclear Information System (INIS)

    The National Science Foundation is advancing the design of a Deep Underground Science and Engineering Laboratory (DUSEL) at the former Homestake mine in South Dakota. UC Berkeley and LBNL are leading the design effort for the facility and coordinating the definition and integration of the suite of experiments to be coupled to the facility design in the creation of an MREFC (Major Research Equipment and Facility Construction) proposal. The State of South Dakota has marshaled $120M to prepare the site and begin a modest science program at the 4850 ft level. The first physics experiment is anticipated to begin installation in 2009. The current timetable calls for the MREFC Preliminary Design to be assembled by 2010 to be presented to the National Science Board in 2011. This, in turn, indicates that the earliest DUSEL construction start would be FY2013. The MREFC is estimated (before the inclusion of the long baseline neutrino components) at $500--600M, roughly divided evenly between the experimental program and support for the facility. Construction was estimated at 6--8 years. The DOE and NSF are establishing a Joint Oversight Group (JOG) to coordinate the experimental programs and participation in DUSEL. It is anticipated that the JOG would mirror the similar function for the NSF and DOE participation in the LHC, and that DOE-HEP, DOE-NP, and NSF will all participate in the JOG. In parallel with the NSF efforts, DOE-HEP plans to develop a long baseline neutrino program with neutrino beams created at FNAL and aimed at DUSEL. In the P5 report the focus of the program is to pursue CP violation in the lepton sector. The same detectors can also be used for nucleon decay experiments. DOE has indicated that FNAL would be the ''lead lab'' for the long baseline neutrino program and be charged with designing and implementing the neutrino beamline. BNL is to be charged with designing and implementing the detector. The P5 report also emphasizes the importance of dark matter and

    2012-12-01

    Due to its interdisciplinary nature, climate science poses wide-ranging challenges for science and mathematics students seeking careers in this field. There is a compelling need for universities to provide coherent programs in climate science in order to train future climate scientists. With funding from NASA Innovations in Climate Education (NICE), California State University, Northridge (CSUN), is creating the CSUN Climate Science Program. An interdisciplinary team of faculty members is working in collaboration with UCLA, Santa Monica College and NASA/JPL partners to create a new curriculum in climate science. The resulting sequence of climate science courses, or Pathway for studying the Mathematics of Climate Change (PMCC), is integrated into a Bachelor of Science degree program in the Applied Mathematical Sciences offered by the Mathematics Department at CSUN. The PMCC consists of courses offered by the departments of Mathematics, Physics, and Geography and is designed to prepare students for Ph.D. programs in technical fields relevant to global climate change and related careers. The students who choose to follow this program will be guided to enroll in the following sequence of courses for their 12 units of upper division electives: 1) A newly created course junior level course, Math 396CL, in applied mathematics which will introduce students to applications of vector calculus and differential equations to the study of thermodynamics and atmospheric dynamics. 2) An already existing course, Math 483, with new content on mathematical modeling specialized for this program; 3) An improved version of Phys 595CL on the mathematics and physics of climate change with emphasis on Radiative Transfer; 4) A choice of Geog 407 on Remote Sensing or Geog 416 on Climate Change with updated content to train the students in the analysis of satellite data obtained with the NASA Earth Observing System and instruction in the analysis of data obtained within a Geographical

    The Science on Saturday Program at Princeton Plasma Physics Laboratory consists of a series of Saturday morning lectures on various topics in science by scientists, engineers, educators, and others with an interesting story. This program has been in existence for over twelve years and has been advertised to and primarily aimed at the high school level. Topics ranging from superconductivity to computer animation and gorilla conservation to pharmaceutical design have been covered. Lecturers from the staff of Princeton, Rutgers, AT and T, Bristol Meyers Squibb, and many others have participated. Speakers have ranged from Nobel prize winners, astronauts, industrialists, educators, engineers, and science writers. Typically, there are eight to ten lectures starting in January. A mailing list has been compiled for schools, science teachers, libraries, and museums in the Princeton area. For the past two years AT and T has sponsored buses for Trenton area students to come to these lectures and an effort has been made to publicize the program to these students. The series has been very popular, frequently overfilling the 300 seat PPPL auditorium. As a result, the lectures are videotaped and broadcast to a large screen TV for remote viewing. Lecturers are encouraged to interact with the audience and ample time is provided for questions.

    BRIKEN is a complex detection system to be installed at the RIB-facility of the RIKEN Nishina Center. It is aimed at the detection of heavy-ion implants, $\\beta$-particles, $\\gamma$-rays and $\\beta$-delayed neutrons. The whole detection setup involves the Advanced Implantation Detection Array (AIDA), two HPGe Clover detectors and a large set of 166 counters of 3He embedded in a high-density polyethylene matrix. This article reports on a novel methodology developed for the conceptual design and optimisation of the 3He-tubes array, aiming at the best possible performance in terms of neutron detection. The algorithm is based on a geometric representation of two selected parameters of merit, namely, average neutron detection efficiency and efficiency flatness, as a function of a reduced number of geometric variables. The response of the detection system itself, for each configuration, is obtained from a systematic MC-simulation implemented realistically in Geant4. This approach has been found to be particularly u...

  3. National Uranium Resource Evaluation Program: the Hydrogeochemical Stream Sediment Reconnaissance Program at LLNL

    International Nuclear Information System (INIS)

    From early 1975 to mid 1979, Lawrence Livermore National Laboratory (LLNL) participated in the Hydrogeochemical Stream Sediment Reconnaissance (HSSR), part of the National Uranium Resource Evaluation (NURE) program sponsored by the Department of Energy (DOE). The Laboratory was initially responsible for collecting, analyzing, and evaluating sediment and water samples from approximately 200,000 sites in seven western states. Eventually, however, the NURE program redefined its sampling priorities, objectives, schedules, and budgets, with the increasingly obvious result that LLNL objectives and methodologies were not compatible with those of the NURE program office, and the LLNL geochemical studies were not relevant to the program goal. The LLNL portion of the HSSR program was consequently terminated, and all work was suspended by June 1979. Of the 38,000 sites sampled, 30,000 were analyzed by instrumental neutron activation analyses (INAA), delayed neutron counting (DNC), optical emission spectroscopy (OES), and automated chloride-sulfate analyses (SC). Data from about 13,000 sites have been formally reported. From each site, analyses were published of about 30 of the 60 elements observed. Uranium mineralization has been identified at several places which were previously not recognized as potential uranium source areas, and a number of other geochemical anomalies were discovered

  4. Nuclear Safeguards and Security Degree Program at Tomsk Polytechnic University

    International Nuclear Information System (INIS)

    Recent increased interest in nuclear energy, including sensitive fuel cycle technologies, has focused attention on the nonproliferation of nuclear weapons. Also, new threats appeared, such as terrorist organizations. One of the most important parts of the nonproliferation regime is nuclear material protection, control, and accounting (MPC and A), which should correspond to current threats. In Russia, as in many other countries, there is a need for specialists in MPC and A. Moscow Engineering Physics Institute (MEPhI) and Tomsk Polytechnic University (TPU), leading centers in nuclear engineering education, have been charged with developing degree programs in the field of safeguards and physical protection. With U.S. support, MEPhI developed a master's degree program in MPC and A and is developing a 5 1/2-year engineering degree program (EDP). During the past three years, the faculty of Applied Physics of TPU has been developing its own EDP that is focused on preparing graduates for MPC and A work in nuclear facilities primarily in Siberia. The first students will graduate in 2008. MEPhI is assisting TPU in developing the academic program. There is some international cooperation in the development of TPU's EDP. The U.S. Department of Energy is one of the most active participants in this work. In particular, the TPU educational program is being developed within the framework of contracts with PNNL and with the participation of Los Alamos National Laboratory (LANL). A unique and valuable feature of TPU's EDP is close connection with real industrial processes. This is realized through a relationship with the Siberia Chemical Combine (SCC) at Seversk, just 15 miles from Tomsk. SCC has most elements of the nuclear fuel cycle. Plans are being made to utilize SCC experts, material, and facility space for lab exercises. This paper describes steps recently taken and future plans to further develop the EDP at Tomsk

  5. Plans for correlation studies for BES program at RHIC

    International Nuclear Information System (INIS)

    We present an overview of the main concepts concerning correlation studies for the Beam Energy Scan Program at STAR. QGP signatures at higher RHIC energies are the most obvious example of the creation of a new state of matter. In order to learn more about the transition to this state and to find a possible location of a critical point between a first-order transition and cross-over area, a new program dedicated to such analyses is formulated. Correlation studies are one of the most important observables of the scanning of unknown region of the phase diagram. Measurements of elliptic flow, local parity violation in strong interactions, azimuthally sensitive correlations as well as two-proton femtoscopy and nonidentical particle correlations are discussed in this paper

    2012-05-15

    We describe a future possible upgrade of the European XFEL consisting in the construction of an undulator beamline dedicated to life science experiments. The availability of free undulator tunnels at the European XFEL facility offers a unique opportunity to build a beamline optimized for coherent diffraction imaging of complex molecules, like proteins and other biologically interesting structures. Crucial parameters for such bio-imaging beamline are photon energy range, peak power, and pulse duration. Key component of the setup is the undulator source. The peak power is maximized in the photon energy range between 3 keV and 13 keV by the use of a very efficient combination of self-seeding, fresh bunch and tapered undulator techniques. The unique combination of ultra-high peak power of 1 TW in the entire energy range, and ultrashort pulse duration tunable from 2 fs to 10 fs, would allow for single shot coherent imaging of protein molecules with size larger than 10 nm. Also, the new beamline would enable imaging of large biological structures in the water window, between 0.3 keV and 0.4 keV. In order to make use of standardized components, at present we favor the use of SASE3-type undulator segments. The number segments, 40, is determined by the tapered length for the design output power of 1 TW. The present plan assumes the use of a nominal electron bunch with charge of 0.1 nC. Experiments will be performed without interference with the other three undulator beamlines. Therefore, the total amount of scheduled beam time per year is expected to be up to 4000 hours.

    A new Bachelor of Science in Medical Physics program at Ryerson University, Toronto, Ontario was launched in Fall 2006. The program builds on Ryerson’s strong existing capabilities in biomedical physics research. The program’s point of entry is the common first year during which all students in Biology, Chemistry, Contemporary Science and Medical Physics programs complete the foundation courses that include physics, calculus, biology, chemistry, and introduction to computing. In addition to the foundation courses, the first-year studies include an orientation course that supports the students in making a successful transition to university studies. The courses beyond the first year include such topics as radiation therapy, image analysis, medical diagnostics and computer modeling techniques. In the final year the students will undertake an independent, faculty-supervised thesis project in an area of personal research interest. Co-op and industrial internship options are available. Our program promotes natural interaction between physics, life sciences, mathematics and computing. The flexibility built into our curriculum will open a variety of career options for our graduates.

    2015-10-01

    Most dental school faculty members arrive on campus with a wealth of clinical experience but little to no teacher training. For the past two decades, there has been a call for schools to educate their faculty on a wide variety of topics including educational methodology and cutting-edge educational techniques through faculty development programs. Drawing on theories of general program evaluation as well as evaluation specific to educational programming, the aim of this study was to investigate outcomes of the Faculty Development Program at the University of Missouri-Kansas City School of Dentistry between 2007 and 2014. A mixed-methods research design gathered quantitative data via email survey sent to all eligible teaching faculty members; it received an overall response rate of 54% (N=51). Qualitative data came from open-ended survey questions and a focus group with seven volunteer faculty participants. The survey data suggested that the stated outcomes of faculty development were being met for all stakeholder groups with varying degrees of success. Focus group results indicated a need for a more formal new faculty orientation and better communication with all about the specific charge of faculty development within the school. Evaluation of faculty development activities in academic dental institutions is a necessary component of the ongoing improvement of dental education. Suggestions for future evaluations include the idea of collaborating with other dental schools to increase sample sizes, which would increase participants' perception of the level of confidentiality and make statistical analyses more robust.

  10. Materials balance area Custodian Performance Evaluation Program at PNL

    International Nuclear Information System (INIS)

    The material balance area (MBA) custodian has primary responsibility for control and accountability of nuclear material within an MBA. In this role, the custodian operates as an extension of the facility material control and accountability (MC ampersand A) organization. To effectively meet administrative requirements and protection needs, the custodian must be fully trained in all aspects of MC ampersand A related to the MBA, and custodian performance must be periodically evaluated. DOE Policy requires that each facility provide for a program which assures that each facility provide for a program which assures that personnel performing MC ampersand A functions are (1) trained and/or qualified to perform their duties and responsibilities and (2) knowledgeable of requirements and procedures related to their functions. The MBA Custodian Performance Evaluation Program at PNL uses a variety of assessment techniques to meet this goal, including internal and independent MBA audits, periodic custodian testing, conduct of limited scope performance tests, daily monitoring of MC ampersand A documentation, and reviewing custodian performance during physical inventories. The data collected from these sources is analyzed and incorporated into an annual custodian performance evaluation document, given to each custodian and line management. Development of this program has resulted in significantly improved custodian performance and a marked decrease in finding and observations identified during MBA audits

    Carbon-14 concentrations between 0.83 and 11.79 pmC of formation water from the Activo Samaria-Sitio Grande petroleum reservoir in SE-Mexico, extracted from 3500 to 4500 m.b.s.l., indicate a common infiltration event of surface water during the late Pleistocene period. Mixing of two components - meteoric water and seawater, previously evaporated at the surface - explain the widespread mineralization (TDI = 15-257 g/L) of Na-Cl and Na-Ca-Cl type reservoir water. Statistical discrimination by clustering and a heterogeneous chemical-isotopic fluid composition indicate the existence of 4 different water types as part of local aquifer systems, which are separated by normal and thrust faults. Tectonic horst and graben structures show an ambiguous, individual hydraulic behaviour - as permeable conduits and/or as impermeable barriers, causing the local limitation of aquifer extent. The recent increase of water production in petroleum wells is not related to the injection of surface water, but the long-term extraction of oil reserves is modifying the original position and flow direction of the reservoir aquifers. The rise of the initial groundwater level reflects the final stage of an exhausted petroleum reservoir with coning effects of underlying aquifer systems. The flexible change towards superior production intervals could represent a feasible technique to avoid the abrupt closure of invaded production wells. (Author)

  14. Conceptual, experimental and computational approaches to support performance assessment of hydrology and chemical transport at Yucca Mountain

    International Nuclear Information System (INIS)

    The authors of this report have been participating in the Sandia National Laboratory's hydrologic performance assessment of the Yucca Mountain, Nevada, since 1983. The scope of this work is restricted to the unsaturated zone at Yucca Mountain and to technical questions about hydrology and chemical transport. The issues defined here are not to be confused with the elaborate hierarchy of issues that forms the framework of the US Department of Energy plans for characterizing the site (DOE, 1989). The overall task of hydrologic performance assessment involves issues related to hydrology, geochemistry, and energy transport in a highly heterogeneous natural geologic system which will be perturbed in a major way by the disposal activity. Therefore, a rational evaluation of the performance assessment issues must be based on an integrated appreciation of the aforesaid interacting processes. Accordingly, a hierarchical approach is taken in this report, proceeding from the statement of the broad features of the site that make it the site for intensive studies and the rationale for disposal strategy, through the statement of the fundamental questions that need to be answered, to the identification of the issues that need resolution. Having identified the questions and issues, the report then outlines the tasks to be undertaken to resolve the issues. The report consists essentially of two parts. The first part deals with the definition of issues summarized above. The second part summarizes the findings of the authors between 1983 and 1989 under the activities of the former Nevada Nuclear Waste Storage Investigations (NNWSI) and the current YMP

  15. Conceptual design of an undulator system for a dedicated bio-imaging beamline at the European X-ray FEL

    Geloni, Gianluca; Saldin, Evgeni

    2012-01-01

    We describe a future possible upgrade of the European XFEL consisting in the construction of an undulator beamline dedicated to life science experiments. The availability of free undulator tunnels at the European XFEL facility offers a unique opportunity to build a beamline optimized for coherent diffraction imaging of complex molecules, like proteins and other biologically interesting structures. Crucial parameters for such bio-imaging beamline are photon energy range, peak power, and pulse duration. Key component of the setup is the undulator source. The peak power is maximized in the photon energy range between 3 keV and 13 keV by the use of a very efficient combination of self-seeding, fresh bunch and tapered undulator techniques. The unique combination of ultra-high peak power of 1 TW in the entire energy range, and ultrashort pulse duration tunable from 2 fs to 10 fs, would allow for single shot coherent imaging of protein molecules with size larger than 10 nm. Also, the new beamline would enable imagin...

    NASA has a rich history of scientific research that has been conducted throughout our numerous manned spaceflight programs. This scientific research has included animal test subjects participating in various spaceflight missions, including most recently, Space Shuttle mission STS-131. The Animal Care Program at Johnson Space Center (JSC) in Houston, Texas is multi-faceted and unique in scope compared to other centers within the agency. The animal care program at JSC has evolved from strictly research to include a Longhorn facility and the Houston Zoo's Attwater Prairie Chicken refuge, which is used to help repopulate this endangered species. JSC is home to more than 300 species of animals including home of hundreds of white-tailed deer that roam freely throughout the center which pose unique issues in regards to population control and safety of NASA workers, visitors and tourists. We will give a broad overview of our day to day operations, animal research, community outreach and protection of animals at NASA Johnson Space Center.

  18. Ground heating and methane oxidation processes at shallow depth in Terre Calde di Medolla (Italy): Observations and conceptual model

    Capaccioni, Bruno; Tassi, Franco; Cremonini, Stefano; Sciarra, Alessandra; Vaselli, Orlando

    2015-05-01

    The toponym "Terre Calde di Medolla" (literally, "Warm Earths of Medolla") refers to a farming area, located near the town of Modena (Emilia-Romagna region, northern Italy), which has always been known by the local population for the relatively high temperatures of the soil. This phenomenon is particularly evident in wintertime when the snow cover over this area rapidly melts. A detailed investigation, carried out after the devastating 2012 Emilia earthquake that affected this area, showed soil temperatures up to 44°C, i.e., 20-25°C above the local background value, together with diffuse soil fluxes of CH4 (0-2432 g × m-2 × d-1) and minor, though significant, CO2 (0-1184 g × m-2 × d-1), especially from subcircular (a few meters in diameter) zones. Ground heating and gas seepage appear spatially correlated, thus suggesting a close relationship between the two phenomena. The anomalous high ground temperature is not associated with an anomalous geothermal gradient or with the uprising of deep-seated hot fluids. According to the lateral and vertical distributions of the temperatures as well as the chemical and isotopic compositions of the soil gases, the most reliable explanation is the exothermic oxidation of diffusely uprising biogenic methane at very shallow levels (<1 m). Such a process occurs in the presence of free oxygen and methanotrophic bacteria and can then explain (i) the observed ground heating up, (ii) the diffuse emission from the soil of CO2 characterized by an extremely negative isotopic (13C/12C) signature, and (iii) the lack of diffuse and low CH4 fluxes. According to these hypotheses, the heating phenomena affecting the shallow groundwater and the ground surface, as described by several witnesses in the area of the May-June 2012 Emilia earthquake, could be related to either a coseismic or postseismic onset of new areas affected by CH4 seepage or an increase in preexisting CH4 fluxes.

    International Nuclear Information System (INIS)

    This is a slide-based talk given at the COG/IAEA: 5. Technical Committee Meeting on 'Exchange of operating experience of pressurized heavy water reactors'. In the introduction there are presented the operating experience (OPEX) program of OHN, and the OPEX Program Mission, ensuring that the right information gets to the right staff at the right time. The OPEX Processes are analysed. These are: - Internal Corrective Action; - Inter-site Lesson Transfer; - External Lesson Transfer; - External Posting of OHN Events; - Internalizing Operating Experience. Steps in solving the Corrective Action Program are described: - Identify the Problem; - Notify Immediate Supervision/Manager; - Evaluate the Problem; - Correct the Problem; Monitor/Report Status. The Internal Corrective Action is then presented as a flowchart. The internalizing operating experience is presented under three aspects: - Communication; - Interface; - Training. The following items are discussed, respectively: peer meetings, department/section meetings, safety meetings, e-mail folders, newsletters and bulletin boards; work planning, pre-job briefings, supervisors' briefing cards; classroom initial and refresher (case studies), simulator, management courses. A diagram is presented showing the flow and treatment of information within OHN, centered on the weekly screening meetings. Finally, the corrective action processes are depicted in a flowchart and analysed in details

  20. DWPF Stage 2: precipitation test program at Mott

    International Nuclear Information System (INIS)

    This memorandum covers the results of the test program conducted at Mott Metallurgical to determine cross-flow filter performance on potassium/cesium tetraphenylborate (K/Cs TPB)-sodium titanate slurries. The test program was designed to provide essential basic operating data to supplement the 1000-gallon cold process tests planned at TNX and the shielded cell tests with actual waste supernate planned by Chemical Technology. The specific Mott Metallurgical test objectives are outlined in DPST-81-722. During the Mott Metallurgical test program an average filtrate flow rate of approximately 0.05 gpm/ft2 was repeatedly demonstrated over an 8-hr run with 0.5 micron filter elements. Initial Fe/Al sludge concentrations up to 150 ppM did not affect filter performance. Rheologies of the K/Cs TPB-sodium titanate slurries up to 13% by weight, the maximum concentration achieved, are summarized. Several recommendations are made to act as a guide for optimal filter performance

    The X-ray astronomy group at the Marshall Space Flight Center is developing electroformed nickel/cobalt x-ray optics for suborbital and orbital experiments. Suborbital instruments include the Focusing X-ray Solar Imager (FOXSI) and Micro-X sounding rocket experiments and the HERO balloon payload. Our current orbital program is the fabrication of a series of mirror modules for the Astronomical Roentgen Telescope (ART) to be launched on board the Russian-German Spectrum Roentgen Gamma Mission (SRG.) The details and status of these various programs are presented. A second component of our work is the development of fabrication techniques and optical metrology to improve the angular resolution of thin shell optics to the arcsecond-level. The status of these x-ray optics technology developments is also presented.

  2. Decommissioning programs and strategies of basic nuclear installations at COGEMA

    International Nuclear Information System (INIS)

    In France, a lot of decommissioning projects were initiated over the last past decades permitting the French nuclear industry to acquire a great experience and knowledge in the field of dismantling. It started in the 1970's when the French Atomic Energy Agency (CEA) began to dismantle research and pilot reactors, laboratories and pilot facilities such as AT1, a pilot reprocessing plant for fast breeder spent fuels located in La Hague. The COGEMA group which is world-leader in the nuclear fuel cycle from uranium prospecting to spent fuel reprocessing and recycling (including refining, conversion, enrichment of natural uranium, manufacturing of nuclear fuels and waste conditioning), has already been involved in several nuclear clean-up and decommissioning programs. This presentation is illustrating the main decommissioning programs of COGEMA Basic Nuclear Installations within the nuclear fuel cycle, the associated initial feed back and chosen strategies

    Hill, G.

    In this paper I outline the \\fortran programs available at the DAO to process and synthesize spectra, loosely described under the generic name REDUCE. The viewpoint is that of a research scientist who develops and uses his own software, and who writes collaboratively for colleagues. Much of the software has been available on the DAO's VAX machines since the early 80s and is slowly being converted to SUNs, although recent developments involve the use of DEC Alphas. The rationale behind the various reduction and analytic software is outlined, as well as the way the programs are controlled, e.g., menu, questions and answers, keywords and values, or the cursor. Some particularly useful tools are mentioned, such as, interpolation, optimization, and error analysis.

    The cross-section sensitivity analysis program at ORNL is reviewed with emphasis on present computer code capabilities and fast successful applications in the radiation shielding area. The FORSS sensitivity code system is discussed in regard to objectives, methodology, and code specifications. Examples of past shielding applications of FORSS emphasize the success of fine energy grid sensitivity studies and group structure selection, the use of evaluated error file and problem uncertainty estimation, two-dimensional shield sensitivity analysis and integral experiment design for fast reactors, data studies for the LMFBR program related to sodium and iron evaluations and iron data problems in CTR shielding design. Conclusions are drawn about the adequacy of present ENDF/B data files for sodium and iron and the general applicability of sensitivity studies in future design and analysis. 16 figures, 3 tables

    The study of the transverse momentum dependent parton distributions (TMDs) of the nucleon in semi-inclusive deep-inelastic scattering (SIDIS) has emerged as one of the major physics motivations driving the experimental program using the upgraded 11 GeV electron beam at Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF). The accelerator construction phase of the CEBAF upgrade is essentially complete and commissioning of the accelerator has begun as of April, 2014. As the new era of CEBAF operations begins, it is appropriate to review the body of published and forthcoming results on TMDs from the 6 GeV era of CEBAF operations, discuss what has been learned, and discuss the key challenges and opportunities for the 11 GeV SIDIS program of CEBAF.

    2016-01-01

    Objective: This review examines studies on mindfulness based programs used with adolescents at-risk for poor future outcomes such as not graduating from high school and living in poverty. Method: The keywords used include mindfulness, at-risk and adolescents in each database to search CINAHL (10 items: 2 book reviews, 3 Dissertations, and 5 research articles), Medline EBSCO (15 research articles), and PubMed (10 research articles). Only primary research articles published between 2009- 2015 in English on mindfulness and at-risk adolescents were included for the most current evidence. Results: Few studies (n= 11) were found that investigate mindfulness in at-risk adolescents. These studies used various mindfulness programs (n = 7) making it difficult to generalize findings for practice. Only three studies were randomized control trials focusing mostly on male students with low socioeconomic status and existing mental health diagnoses. Conclusion: There is a relationship between health behaviors and academic achievement. Future research studies on mindfulness based interventions need to expand to its effects on academic achievement in those youth at-risk to decrease problematic behaviors and improve their ability to be successful adults.

  8. Preliminary thermal/thermomechanical analyses of the Site Characterization Plan's Conceptual Design for a repository containing horizontally emplaced waste packages at the Deaf Smith County site

    International Nuclear Information System (INIS)

    This report presents thermal/thermomechanical analyses of the Site Characterization Plan Conceptual Design for horizontal package emplacement at the Deaf Smith County site, Texas. The repository was divided into three geometric regions. Then two-dimensional finite-element models were set up to approximate the three-dimensional nature of each region. Thermal and quasistatic thermomechanical finite-element analyses were performed to evaluate the thermal/thermomechanical responses of the three regions. The exponential-time creep law was used to represent the creep behavior of salt rock. The repository design was evaluated by comparing the thermal/thermomechanical responses obtained for the three regions with interim performance constraints. The preliminary results show that all the performance constraints are met except for those of the waste package. The following factors were considered in interpreting these results: (1) the qualitative description of the analytical responses; (2) the limitations of the analyses; and (3) either the conclusions based on overall evaluation of limitations and analytical results or the conclusions based on the fact that the repository design may be evaluated only after further analyses. Furthermore, a parametric analysis was performed to estimate the effect of material parameters on the predicted thermal/thermomechanical response. 23 refs., 34 figs., 9 tabs

    The Former Radiation Worker Medical Surveillance Program at Rocky Flats was conducted in Arvada, CO, by Oak Ridge Associated Universities through the Oak Ridge Institute for Science and Education under DOE Contract DE-AC05-00OR22750. Objectives of the program were to obtain information on the value of medical surveillance among at-risk former radiation workers and to provide long-term internal radiation dosimetry information to the scientific community. This program provided the former radiation workers of the Rocky Flats Environmental Technology Site (formerly Rocky Flats Plant) an opportunity to receive follow-up medical monitoring and a re-evaluation of their internal radiation dose. The former Rocky Flats radiation worker population is distinctive because it was a reasonably stable work force that received occupational exposures, at times substantial, over several decades. This report reflects the summation of health outcomes, statistical analyses, and dose assessment information on former Rocky Flats radiation workers to the date of study termination as of March 2004.

    International Nuclear Information System (INIS)

    The reliability-centered maintenance (RCM) program at Rochester Gas ampersand Electric Company's Ginna station is entering its second year. Of the 20 systems originally selected for evaluation, 10 are in various stages of completion, and recommendations resulting from the earliest systems studied are now being implemented. As expected, few major discoveries have been made in terms of preventive maintenance program failings or excesses. The performance of the now 20-yr-old plant has been excellent in recent years, and objectives focus more on ensuring continued high standards of safety, reliability, and economy than on maintenance program cost reduction

    The Canadian nuclear power generation industry, represented by the CANDU Owners Group (COG), has been funding an experimental program at Chalk River Laboratories (CRL) to study the interaction between molten material ejected from a fuel channel and the moderator. These experiments were designed to address one of the very low probability postulated accident events considered for CANDU Pressurized Heavy Water Reactors. The reactor consists of an array of horizontal fuel channels that contain the UO{sub 2}, nuclear fuel and high-temperature, high-pressure heavy water coolant. Under severely restricted flow blockage conditions, approaching 100% reduction of the flow area, postulated in a fuel channel, the temperature excursion could result in fuel melting, consequential failure of the fuel channel, and ejection of the molten fuel at high pressures into the heavy water moderator at near atmospheric pressure. In preparation for these tests, a chemical mixture called a thermite, that could produce a simulated molten fuel when ignited, was developed in partnership with Argonne National Laboratory (USA). Following this thermite development, two base-case reference tests were completed. The two base-case reference tests, with no molten material present, were performed in the Molten-Fuel Moderator-Interaction (MFMI) facility at CRL. Following the base-case reference tests, a high-pressure melt ejection test using prototypical corium was conducted. The objectives of this paper are to provide an overview of the MFMI program and present the results obtained from thermite development, base-case and melt ejection experiments. (author)

  15. A program for conducting corrective actions at operating industrial facilities

    International Nuclear Information System (INIS)

    The purpose of this paper is to present a proactive, comprehensive program to assist industries in gaining control over the corrective actions required to address historic contaminant releases (such as oil spills fuel distribution times, and other contaminants such as diesel and jet fuels) while at the same time minimizing their impact on facility operations. In contrast to the approach used by many industries, this program emphasizes a proactive approach in which a strategy is developed to meet the needs of both the facility and the regulators. Development of the strategy includes: conducting a comprehensive self-evaluation of environmental problems; identifying applicable corrective action regulations; developing a risk-based priority ranking of sites requiring corrective actions; preparing an overall strategy/schedule to perform the corrective actions; and obtaining the support/approval of corporate management and the regulators. The program meets the needs of the regulators in that it presents a long-term commitment by the facility to assure the protection of public health and the environment, thereby minimizing enforcement need for regulatory oversight and delays caused by the need for regulatory approvals

  16. Audit program for physical security systems at nuclear power plants

    International Nuclear Information System (INIS)

    Licensees of nuclear power plants conduct audits of their physical security systems to meet the requirements of 10 CFR 73, Physical Protection of Plants and Materials. Section 73.55, Requirements for physical Protection of Licensed Activities in Nuclear Power Reactors Against Radiological Sabotage, requires that the security programs be reviewed at least every 12 months, that the audit be conducted by individuals independent of both security management and security supervision, and that the audit program review all aspects of the physical security system: hardware, personnel, and operational and maintenance procedures. This report contains information for the Nuclear Regulatory Commission (NRC) and for the licensees of nuclear power reactors who carry out these comprehensive audits. Guidance on the overall management of the audit function includes organizational structure and issues concerning the auditors who perform the review: qualifications, independence, due professional care, and standards. Guidance in the audit program includes purpose and scope of the audit, planning, techniques, post-audit procedures, reporting, and follow-up

  17. The RERTR demonstration experiments program at the Ford Nuclear Reactor

    International Nuclear Information System (INIS)

    The purpose of this paper is to highlight a major part of the experimental work which is being carried out at the Ford Nuclear Reactor (FNR) in conjunction with the RERTR program. A demonstration experiments program has been developed to: 1) characterize the FNR in sufficient detail to discern and quantify neutronic differences between the high and low enriched cores; 2) provide the theoretical group with measurements to benchmark their calculations. As with any experimental program associated with a reactor, stringent constraints limit the experiments which can be performed. Some experiments are performed routinely on the FNR (such as control rod calibrations), and much data is already available. Unfortunately, the accuracy we demand precludes using much of this earlier data. And in many cases, the requirement of precise (and copious) data has led to either developing new techniques (as in the case of rhodium mapping and neutron diffraction) or to further refinements on existing methods (as in the case of spectral unfolding). Nevertheless, we have tried to stay within the realm of recognized, well-established experimental methods in order to assuage any doubts about measured differences between HEU and LEU core parameters. This paper describes the principal results of the experiments performed so far

It is the largest-scale fuel-pin experiment in the present program and will provide data on the performance of pins and a pin-support structure that are prototypic of the GCFR Demonstration Plant. The fuel pins are presently undergoing interim examination after successfully achieving 4.6 at.% burnup. Studies of the thermodynamics and kinetics of the U--Cs--O system, supplemented by analysis of the results of previously irradiated fuel pins, have led to the incorporation of fuel-design modifications in the F-5 experiment to insure adequate performance of the vented fuel. The effect of ribbing, as well as the ribbing process, on the short- and long-term structural performance of fuel-pin cladding is being evaluated via in-reactor and out-of-reactor tests and with the fuel-element modeling code LIFE-GCFR and the finite element program, ADINA

    The Monterey Bay Aquarium Research Institute formally started the Internship Program in 1997. The program is open to undergraduate and graduate students and educators. The purpose of the Program is to provide an opportunity for talented students and teachers to come to MBARI for a certain period of time and to work on a research project under MBARI staff supervision. The interns are selected following a rigorous application procedure, merit review and, in some cases, an interview process. They are from around the world and represent a variety of different backgrounds, experience, and education. They all share a common desire to learn more about the marine environment and to work with MBARI staff. The mission of the Monterey Bay Aquarium Research Institute is to serve as a world center for advanced research and education in ocean science and technology. MBARI strives to achieve this mission through the development of better instruments, systems, and methods for scientific research in the deep ocean. MBARI emphasizes peer relationships between engineers and scientists as a basic principle of its operation. Teams at MBARI use cutting-edge technology to develop equipment, software, and research methods to meet the specific needs of deep-sea research. The focus of the MBARI internship is on the intern’s professional development—learning research techniques and improving communication and collaboration skills. Each intern has an MBARI mentor who will supervise a specific project. Interns will also serve as peer-mentors to other interns. This presentation will provide a brief overview of the history of the program as well as lessons learned. 2009 MBARI SUMMER INTERNS WITH PRESIDENT AND CEO MARCIA MCNUTT

  4. Development of a Conceptual Model for Vadose Zone Transport of Tc-99 at Hanford's BC Cribs and the Screening of Remedial Alternatives

    International Nuclear Information System (INIS)

    A number of waste trenches and cribs at Hanford's BC Cribs and Trenches site, which received about 10 Mgal of scavenged tank waste with elevated concentrations of technetium-99 and nitrate, are being evaluated for remediation. The objectives of this study were to: 1) develop a conceptual model for vadose zone transport of mobile contaminants, and 2) investigate the effects of fine-scale heterogeneity (i.e. horizontal laminations, cross-bedding) on the large-scale transport behavior with the goal of developing an appropriate remedial strategy. The vertical heterogeneity structure, conditioned on grain size distributions and borehole geophysical logs (water content and natural isotopes), was developed from a single borehole at the site. Geostatistical methods were used to impose a 3-D spatial correlation structure, using information from an adjacent well-characterized experimental site, and to merge heterogeneities at various scales. Flow and transport properties were derived using property transfer models based on grain size distributions. The STOMP simulator was used to predict flow and transport through the vadose zone and into a 5-m thick confined aquifer during the period of trench operations (1956-1958) through to the present time. Results show that fine-scale heterogeneity within the large-scale lithologic units enhanced lateral flow and mixing, limited vertical penetration in the vadose zone, and played a critical role in keeping contaminants above the water table. Model results show good agreement with a contaminant profile from a borehole installed in the 216-B-26 trench. Simulated distributions of nitrate and electrical resistivity are also in good agreement with the results of a field-scale resistivity survey. These results suggest that installation of an engineered surface barrier would reduce the threat to ground water by reducing the mass flux of contaminants to the water table and increasing the residence time in the vadose zone.

  8. Foreign Material Exclusion Program at CNE Cernavoda Nuclear Generating Station

    International Nuclear Information System (INIS)

    In the face of a continuing attention to operations and maintenance costs at nuclear power plants, the future of the industry depends largely upon increasing plant availability and improving operating efficiency. The success in achieving these objectives is dependent upon the success of each plant's equipment maintenance program. Preventing the introduction of foreign materials into a nuclear power plant system or component requires a careful, thoughtful, and professional approach by all site personnel. This paper describes a proactive approach to prevent the introduction of foreign material into systems and components, by providing an overview of technical considerations required to develop, implement, and manage a foreign material exclusion program at CNE Cernavoda Unit 1 and 2 Nuclear Power Station. It is also described an example of Foreign Material Intrusion which happened during the 2003 planned maintenance outage at Cernavoda Unit no.1. This paper also defines personnel responsibilities and key nomenclature and a means for evaluating prospective work tasks and activities against standardized criteria, in order to identify the appropriate level of the required FME controls.

  9. Future of the Beam Energy Scan program at RHIC

    International Nuclear Information System (INIS)

    The first exploratory phase of a very successful Beam Energy Scan Program at RHIC was completed in 2014 with Au+Au collisions at energies ranging from 7 to 39 GeV. Data sets taken earlier extended the upper limit of energy range to the √sNN of 200 GeV. This provided an initial look into the uncharted territory of the QCD phase diagram, which is considered to be the single most important graph of our field. The main results from BES phase I, although effected by large statistical errors (steeply increasing with decreasing energy), suggest that the highest potential for discovery of the QCD Critical Point lies bellow √sNN 20 GeV. Here, we discuss the plans and the preparation for phase II of the BES program, with an order of magnitude larger statistics, which is planned for 2018-2019. The BES II will focus on Au+Au collisions at √sNN from 20 to 7 GeV in collider mode, and from √sNN 7 to 3.5 GeV in the fixed target mode, which will be run concurrently with the collider mode operation

  11. Nuclear Data Experimental Program at CERN for Reactor Physics

    International Nuclear Information System (INIS)

    The neutron time-of-flight facility n-TOF, operating at CERN since 2001, features a neutron beam that covers the energy range from thermal to 1 GeV. Its most outstanding characteristics are its long flight path (185 m) and the high instantaneous intensity (0.5-12·106 neutrons/pulse depending on the collimator configuration). The ambitious program carried out in the last decade includes a large number of experiments in the fields of nuclear energy technologies, astrophysics, basic physics, detector development and medical applications. Within the field of nuclear energy technologies most measurements are focused on determining, for the first time and/or with unprecedented accuracies, the capture and fission cross sections of actinides, both at low (resolved resonance region) and high (keV-GeV) neutron energies. This paper present a summary of all the measurements carried out since 2001 at n-TOF, including some details for several of these experiments. (author)

  12. Status of LEU programs at Babcock and Wilcox

    International Nuclear Information System (INIS)

    Within the Low Enriched Programs being conducted at Babcock and Wilcox the primary effort has been to establish, from past LEU development work and current production technology, an efficient production process that maintains product quality for both LEU UAlx and U3Si2 elements. This effort has allowed the Babcock and Wilcox Company to successfully complete a second LEU production contract for the 2-MW Ford Nuclear Reactor at the University of Michigan. Current U3Si2 contracts which include Standard and Control Elements for the Oak Ridge Reactor, SAPHIR Elements for the Swiss Federal Institute for Reactor Research, silicide (U3Si2) powder for the Danish Riso National Laboratory and Elements for Sweden's R2 Reactor at Studsvik are being manufactured under the same guidelines of quality and efficiency improvements. The transition from developmental work to a production process for powder fabrication; compacting; plate and element fabrication along with inspection methods are highlighted within this report.

    The Advanced Computer Program at Fermilab has developed a multiprocessor system which is easy to use and uniquely cost effective for many high energy physics problems. The system is based on single board computers which cost under $2000 each to build including 2 Mbytes of on board memory. These standard VME modules each run experiment reconstruction code in Fortran at speeds approaching that of a VAX 11/780. Two versions have been developed: one uses Motorola's 68020 32 bit microprocessor, the other runs with AT and T's 32100. both include the corresponding floating point coprocessor chip. The first system, when fully configured, uses 70 each of the two types of processors. A 53 processor system has been operated for several months with essentially no down time by computer operators in the Fermilab Computer Center, performing at nearly the capacity of 6 CDC Cyber 175 mainframe computers. The VME crates in which the processing ''nodes'' sit are connected via a high speed ''Branch Bus'' to one or more MicroVAX computers which act as hosts handling system resource management and all I/O in offline applications. An interface from Fastbus to the Branch Bus has been developed for online use which has been tested error free at 20 Mbytes/sec for 48 hours. ACP hardware modules are now available commercially. A major package of software, including a simulator that runs on any VAX, has been developed. It allows easy migration of existing programs to this multiprocessor environment. This paper describes the ACP Multiprocessor System and early experience with it at Fermilab and elsewhere.

    Objective: To provide a conceptual framework for managing diabetic patient care, and creating an information network for clinical research. Background: A wide range of information technology (IT) based interventions such as distance learning, diabetes registries, personal or electronic health record systems, clinical information systems, and clinical decision support systems have so far been used in supporting diabetic care. Previous studies demonstrated that IT could improve diabetes care at its different aspects. There is however no comprehensive conceptual framework that defines how different IT applications can support diverse aspects of this care. Therefore, a conceptual framework that combines different IT solutions into a wide information network for improving care processes and for research purposes is widely lacking. In this study we describe the theoretical underpin of a big project aiming at building a wide diabetic information network namely DIANET. Research design and methods: A literature review and a survey of national programs and existing regulations for diabetes management was conducted in order to define different aspects of diabetic care that should be supported by IT solutions. Both qualitative and quantitative research methods were used in this study. In addition to the results of a previous systematic literature review, two brainstorming and three expert panel sessions were conducted to identify requirements of a comprehensive information technology solution. Based on these inputs, the requirements for creating a diabetes information network were identified and used to create a questionnaire based on 9-point Likert scale. The questionnaire was finalized after removing some items based on calculated content validity ratio and content validity index coefficients. Cronbach’s alpha reliability coefficient was also calculated (αTotal= 0.98, P<0.05, CI=0.95). The final questionnaire was containing 45 items. It was sent to 13 clinicians at two

  16. The PANDA detector and its physics program at FAIR

    International Nuclear Information System (INIS)

    The PANDA detector will make use of the antiprotons produced in the FAIR complex and stored in the High-Energy Storage Ring HESR for the study of strong interactions in antiproton collisions with protons and heavy targets. The detector features a 4π design for charged particles with a solenoidal magnetic field and full coverage of photons by means of an advanced electromagnetic calorimeter. In addition, a dipole spectrometer will allow high-resolution detection of leading particles characteristic for fixed-target experiments. The physics program of PANDA covers a wide range of topics which address central issues of QCD at low and moderate energies. Spectroscopy of hidden charm in the ccbar level scheme is still a very interesting issue, in particular when states are involved which cannot directly be formed in e+e- reactions. Open charm in the D meson section has recently received renewed interest when states were discovered that are not easily explained in conventional qqbar models. Exotic hadrons and glueballs have been predicted by theory within the energy range covered by PANDA. The search for these and the eventual study of their properties is central to the physics program. Using heavy targets, PANDA intends to study the properties of charm quarks in the hadronic medium. The copious production of baryon-antibaryon pairs at HESR will allow studies using secondary targets for the formation of hypernuclei. Each of these physics topics will be touched while the detector properties needed in order to cover the broad physics program are described. Technical developments and the status of the various detector components will be summarized

  17. Research and development program on dense TPC's at LBL

    International Nuclear Information System (INIS)

    We have initiated a research and development program at LBL to develop high density TPC's. We are motivated by their potential use as tracking calorimeters to study nucleon decay. They may also be useful in the study of cosmic neutrino fluxes, double β decay and other low rate processes. Of these applications, the use of dense TPC's to study nucleon decay is the most challenging one because it requires instrumenting very large masses. Our R and D program is aimed at developing large TPC's which are competitive in cost with other proposed nucleon decay detectors while offering superior capabilities for energy resolution, particle identification and uniformity of response. There are two ways of obtaining high density TPC's: the first is to use a cryogenic liquid such as liquid argon or liquid methane; the second is to pressurize a gas such as argon or methane to several hundred atmospheres where the density of the gas approaches that of the liquid state. While we are interested in studying both approaches, we are concentrating on the high pressure approach since it offers the potential advantage of proportional wire amplification. A wire amplification of about 3 orders of magnitude would eliminate the noise problems which are inherent in ionization mode detectors such as liquid argon chambers. A possible 10 kton detector is described, and its properties are discussed in terms of tracking, energy measurements and particle identification

  20. Configuration Management Program Application at KNPP Units 5 and 6 Modernization Program

    International Nuclear Information System (INIS)

    The need for Configuration Management Program development, became very clear after the initiation of the Modernization Program for Units 5and6, because KNPP personnel needed a good and safe way to control the huge amount of data which were transferred into two directions - input data (design and operational documents from KNPP to Contractors) and the design, vendor, procurement, etc. documents (from Contractors to KNPP). Moreover, most of the measures are in fact design changes and it appeared to be extremely important to track these design changes and their reflection into design and operational documents. It is even more important to obtain a successful transfer of all this information to the operating organization (EP-2) after the completion. The proposal for development of Configuration Management (CM) Program for KNPP Units 5and6 Modernization program was divided into three phases: 1. Information Control (Document Control and Records Management) 2.Technical Decision System (Change Control) 3. Master Equipment List (MEL), (as part of the Design requirements element) Information Control Element was chosen to be developed first. Implementation of Information Control element comprised of: Review and assessment of existing situation (procedures for document control and records Management), Development of new/revision of existing procedure for Document Control and Records Management, Development of SmartDoc software application in support of document control and records management and for measure documentation tracking (with its specifics), Data entry for MP5and6 measures, Implementation at EP-2 (with successful data migration from the existing databases). The SmartDoc development was completed at the end of 2002 and after a testing period it was implemented at Modernization and Investment Department first. Then the data for documents were transferred from the existing databases at EP-2 and the system was implemented at EP-2 and other KNPP facilities. Development

    The Center of Applied Space Technology and Microgravity (ZARM) founded by Prof. Dr.-Ing. Hans J. Rath in 1985 is part of the Department of Production Engineering at the University of Bremen, Germany. ZARM established as a research center and currently headed by Prof. Dr. Claus Lämmerzahl is mainly concentrated on fundamental investigations of gravitational and space-related phenomenas under conditions of weightlessness as well as questions and developments related to technologies for space. At ZARM more than 70 scientists, engineers and administrative staff as well as many students from different departments are employed. Today, ZARM is still one of the largest and most important university institutes for space sciences and technologies in Europe as well as worldwide well known in the space community. With a height of 146 m the Bremen Drop Tower is the predominant facility of ZARM and also the only drop tower of its class in Europe. ZARM’s ground-based laboratory offers the opportunity for daily short-term experiments under conditions of high-quality weightlessness at a level of 10 (-6) g (microgravity). The provided quality is one of the purest for experiments under weightlessness worldwide achieved. The scientists may choose between a single drop experiment with 4.74 s in simple free fall and a catapult experiment with 9.3 s of weightlessness. Either in the drop or in the worldwide unique catapult operation routine the repetition rates of microgravity experiments at ZARM are always the same, generally up to 3 times per day. Since the start of operation of the facility in 1990, over 6750 launches of more than 160 different experiment types from various scientific fields like Fundamental Physics, Combustion, Fluid Dynamics, Planetary Formation / Astrophysics, Biology and Materials Sciences have been successfully accomplished so far. In our paper we will report and inform about microgravity experiment programs for students like „Drop Your Thesis!“ by ESA and

    1998-11-01

    The University of Texas at El Paso (UTEP) is located on 300 acres, only a few hundred years from the US/Mexico border. The DOE Infrastructure Support Program was initiated at UTEP in 1987. The purpose of the program was to assist the University in building the infrastructure required for its emerging role as a regional center for energy-related research. Equally important was the need to strength the University`s ability to complete for sponsored energy-related programs at the state and national levels and to provide opportunities for faculty, staff and students to participate in energy-related research and outreach activities. The program had four major objectives, as follows: (1) implement energy research, outreach and demonstration projects already funded, and prepare new proposals to fund university research interests; (2) establish an Energy Center as a separate operational entity to provide continuing infrastructure support for energy-related programs; (3) strengthen university/private sector energy research linkages; and (4) involve minority graduate and undergraduate students in energy research and outreach activities. Each of the above objectives has been exceeded substantially, and, as a consequence, the University has become a regional leader in energy and environmental research and outreach efforts.

  5. High energy physics program at Texas A and M University

    International Nuclear Information System (INIS)

    The Texas A ampersand M experimental high energy physics program continued to reach significant milestones in each of its research initiatives during the course of the past year. We are participating in two major operating experiments, CDF and MACRO. In CDF, the Texas A ampersand M group has spearheaded the test beam program to recalibrate the Forward Hadron Calorimeter for the upcoming CDF data run, as well as contributing to the ongoing analysis work on jets and b-quarks. In MACRO, we have assisted in the development of the final version of the wave form digitizing system being implemented for the entire scintillator system. The construction of the first six supermodules of the detector has been completed and all six are currently taking data with streamer chambers while four have the completed scintillator counter system up and running. We have built and tested prototypes of a liquid-scintillator fiber calorimeter system, in which internally reflecting channels are imbedded in a lead matrix and filled with liquid scintillator.

    The Texas A M experimental high energy physics program continued to reach significant milestones in each of its research initiatives during the course of the past year. We are participating in two major operating experiments, CDF and MACRO. In CDF, the Texas A M group has spearheaded the test beam program to recalibrate the Forward Hadron Calorimeter for the upcoming CDF data run, as well as contributing to the ongoing analysis work on jets and b-quarks. In MACRO, we have assisted in the development of the final version of the wave form digitizing system being implemented for the entire scintillator system.

    2003-01-01

    Consistent with the call of the Minnesota Symposium for new theory in knowledge management, we offer a new conceptualization of Knowledge Management Systems (KMS) as a portfolio of personalized knowledge delivery services. Borrowing from research on online consumer behavior, we describe the challenges imposed by personalized knowledge delivery services, and suggest design parameters that can help to overcome these challenges. We develop our design constructs through a set of hypotheses and discuss the research implications of our new conceptualization. Finally, we describe practical implications suggested by our conceptualization - practical suggestions that we hope to gain some experience with as part of an ongoing action research project at our partner organization.

  12. PHENIX Conceptual Design Report

    Energy Technology Data Exchange (ETDEWEB)

    Nagamiya, Shoji; Aronson, Samuel H.; Young, Glenn R.; Paffrath, Leo

    1993-01-29

    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The e[mu] coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study [pi][sup 0] and [eta] production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the [phi] meson (via K[sup +]K[sup [minus

    2006-12-31

    Brookhaven National Laboratory has prepared a conceptual design for a world class user facility for scientific research using synchrotron radiation. This facility, called the ''National Synchrotron Light Source II'' (NSLS-II), will provide ultra high brightness and flux and exceptional beam stability. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility. Together these will enable the study of material properties and functions with a spatial resolution of {approx}1 nm, an energy resolution of {approx}0.1 meV, and the ultra high sensitivity required to perform spectroscopy on a single atom. The overall objective of the NSLS-II project is to deliver a research facility to advance fundamental science and have the capability to characterize and understand physical properties at the nanoscale, the processes by which nanomaterials can be manipulated and assembled into more complex hierarchical structures, and the new phenomena resulting from such assemblages. It will also be a user facility made available to researchers engaged in a broad spectrum of disciplines from universities, industries, and other laboratories.

    Jenkins, Juliet; Duffy, Andrew

    2011-11-01

    The Boston University Physics Department was recently awarded a three-year grant from the Physics Teacher Education Coalition (PhysTEC). PhysTEC's main aims are to improve the education of future physics teachers, and to increase the number of qualified physics teachers in the school system. Although there have been over 20 PhysTEC-funded sites across the country, BU is the first PhysTEC site in New England. Our goals with this poster are to raise awareness about PhysTEC, and to talk about what we are doing and what we plan to do at BU with our PhysTEC funding. A key part of the PhysTEC program is the teacher-in-residence (TIR), an experienced physics teacher who comes to campus for a year to promote physics teaching as a profession and to lend their experience to education-related efforts. Our first TIR is Juliet Jenkins. The poster will discuss Ms. Jenkins' role in the Department of Physics and in the School of Education as we move forward with new efforts to promote teaching, including a Learning Assistant program, a pilot studio section of one of our introductory physics courses, and a new education course that allows undergraduate students to observe teachers in the classroom.

  15. The soybean and mungbean improvement programs at AVRDC

    International Nuclear Information System (INIS)

    At the Asian Vegetable Research and Development Center (AVRDC) Soybean, Glycine max (L.) Merr. and mungbean, Vigna radiata (L.) Wilczek are included in the Legume Program for improvement. Germplasm collection in soybean and mungbean are 9,524 and 5,108 respectively. Developing improved selections with early, uniform maturity, high yield, wide adaptability and resistance to diseases and insects are the major breeding objectives for the tropics and subtropics. Genetic diversity and genetic resources are available in the germplasm for most of the desired traits both in soybean as well as mungbean. However, for traits such as soybean rust resistance in soybean and resistance to insects in mungbean are rare. Limited amount of radiation breeding is being employed in cooperation with Korean Atomic Energy Agency to obtain desirable genes in both species. A number of AVRDC identified accessions and breeding lines are being used by the national programs to develop improved cultivars. AVRDC developed breeding selections have been released as new cultivars in Costa Rica, Fiji, Korea, India, Indonesia, Malaysia and Taiwan. (author)

  16. Material balance area custodian performance evaluation program at PNL

    International Nuclear Information System (INIS)

    This paper reports that the material balance area (MBA) custodian has primary responsibility for control and accountability of nuclear material within an MBA. In this role, the custodian operates as an extension of the facility material control and accountability (MC and A) organization. To effectively meet administrative requirements and protection needs, the custodian must be fully trained in all aspects of MC and A related to the MBA, and custodian performance must be periodically evaluated. U.S. Department of Energy (DOE) Policy requires that each facility provide for a program which ensures that personnel performing MC and A functions are trained and/or qualified to perform their duties and responsibilities and knowledgeable of requirements and procedures related to their functions. the MBA Custodian Performance Evaluation Program at Pacific Northwest Laboratory (PNL) uses a variety of assessment techniques to meet this goal, including internal and independent MBA audits, periodic custodian testing, limited scope performance tests, daily monitoring of MC and A documentation, and reviewing custodian performance during physical inventories

  17. TREAT Upgrade Refined Conceptual Design Report

    Energy Technology Data Exchange (ETDEWEB)

    Heineman, J. B.; Pearce, W. R.

    1977-12-01

    The TREAT Upgrade Project is one of the Safety Research Experiment Facilities (SAREF) projects which were identified in 1976 as test facilities necessary to the resolution of key safety issues in the Fast Breeder Reactor (FBR) program. These proposed facilities were recommended as a result of the Experiment Needs and Facilities Study conducted by Argonne National Laboratory for ERDA in early 1976. Volume II of that study presented the initial conceptual design of the TREAT Upgrade, and it specifically described the significant increases in safety experiment capability that this project would provide early in the SAREF program at modest cost. This refined conceptual design report is intended to serve as a current status report emphasizing major changes in scope of the TREAT Upgrade Project. The overall objectives of improved test capability are substantially unchanged, and several sections of the Volume II material which discussed these overall objectives of improved capability for energy deposition and flatness of radial power distribution in larger test fuel bundles are accordingly reiterated or referenced in their entirety. The major changes in scope relate to the more extensive revisions than were envisioned in the earlier study with regard to building and site modifications and other provisions for handling and utilizing the larger test loops. The present status of these design modifications, the reactor modifications, the modified TREAT fuel assemblies, and the Advanced TREAT Loop and other experimental equipment and systems are described in this report. Also presented or discussed are required development activities, the management plan to carry out the project schedule, and a current summary estimate of total project cost and yearly project expenditures.

  19. Radiation protection program at an accelerator facility complex

    International Nuclear Information System (INIS)

    Broad aspects of Radiation Protection Program at the Tyco Healthcare/Mallinckrodt Inc. will be presented with emphasis on Occupational dose, Public dose and ALARA program. Regulatory requirements, compliance and radio nuclides of concern for external exposure and internal contamination will be discussed. The facility is subject to in depth annual inspections by the Nuclear Regulatory Commission (NRC) to ensure compliance with regulations and operating license requirements. The facility is required to have an emergency contingency plan in place. A simulated emergency drill scenario is witnessed and graded by the NRC and state inspectors, with full participation by the fire department and the local hospital. Radiation Safety Officer (RSO) is in charge of all radiological aspects of the facility, and reports to the plant manager directly. The RSO or any of his staff has the authority to stop a job if there is a radiological concern. The Radiation protection organization interfaces with Production, QA and Engineering and ensures there is no conflict with Industrial Safety, OSHA and FDA requirements. Any employee has the right to call the regulatory officials if he/she has a concern. Operational aspects of Radiation protection program such as radiological survey, contamination control and limits, air sample survey, radio active waste processing and record retention requirements are per plant procedures and regulatory requirements. Shielding and administrative requirements for designing a modification to an existing design or a new lab/hot cell is subject to in-depth review and approval by Radiation Safety Committee. Each department has a Dose Reduction Subcommittee which meets periodically to discuss if any changes in procedures or facility can be made to decrease the dose. The subcommittee also trends the dose to ensure it is trending downward. Even though 99Mo/99mTC generators are manufactured at the facility, majority of the dose is from cyclotron maintenance. Total

    There are strong experimental and theoretical evidences that in collisions of heavy ions at relativistic energies nuclear matter undergoes a phase transition to the deconfined state—Quark Gluon Plasma. The caused energy region of such transition was not found at high energy at SPS and RHIC and search for this energy is shifted to lower energies, which will be covered by the future NICA (Dubna), FAIR (Darmstadt) facilities and BES II at RHIC. Fixed target and collider experiments at the NICA facility will work at the energy range from a few AGeV up to √ {{S_{NN}}} = 11GeV GeV and will study the most interesting area on the nuclear matter phase diagram. The most remarkable results were observed in the study of collective phenomena occurring in the early stage of nuclear collisions. Investigation of the collective flow will provide information on Equation of State (EoS) for nuclear matter. Study of the Event-by-Event fluctuations and correlations can give us signals of critical behavior of the system. Femtoscopy analysis provides the space-time history of the collisions. Also, it was found that baryon stopping power revealing itself as a "wiggle" in excitation function of curvature of the (net)proton rapidity spectrum relates to the order of the phase transition. The available observations of an enhancement of dilepton rates at low invariant masses may serve as a signal of the chiral symmetry restoration in hot and dense matter. Due to this fact, measurements of the dilepton spectra are considered to be an important part of the NICA physics program. The study of strange particles and hypernuclei production gives additional information on the EoS and "strange" axis of the QCD phase diagram. In this paper a feasibility of the considered investigations is shown by the detailed Monte Carlo simulations applied to the planned experiments (BM@N, MPD) at NICA.

  4. Perspectives on the Science Advisor Program at Sandia National Laboratories

    International Nuclear Information System (INIS)

    This paper discusses a Science Advisor Program which has been established at Sandia National Laboratories (SNL) for the long term augmentation of math and science instruction in New Mexico schools. Volunteer SNL engineers and scientists team with the faculty of participating schools to enhance the teachers' abilities to capture and hold the student's scientific imagination and develop their scientific skills. This is done primarily through providing laboratory resources, training the teachers how to use those resources, and advising how to obtain them in the future. In its first year, over 140 advisors teamed with 132 schools, for average weekly contact with 500 teachers and 10,000 students. Surveys indicate a general rise in frequency and quality of hands-on science instruction, as well as teacher and student attitudes. An expanded evaluation is planned for subsequent years

  5. Programs of plant life management at NPP Dukovany

    International Nuclear Information System (INIS)

    The program of lifetime management at NPP Dukovany is oriented towards an effective usage of facilities while keeping their safety parameters, mainly concerning nuclear safety. The goal is to achieve maximum usage of the design lifetime under the condition of fulfilling above mentioned requirements. Evaluation procedures have been prepared for selected components. These are subsequently discussed and approved by the State Office of Nuclear Safety. The databases of original data are built up regarding the evaluated components. The input data are completed as well according to the approved procedures. Generally valid approaches based on the evaluation of all possible degradation mechanisms are modified regarding the original status of particular component. The procedures are oriented towards a quantification of residual lifetime. They employ knowledge of initiation and kinetics of degradation mechanisms. They also define mechanisms, which should be quantified. For irreplaceable components or components whose replacement is difficult, the program is focused to the control of operation conditions and inspection of facilities. However, they are again based on the knowledge of degradation kinetics. If at least some parts of the facility could be replaced, better material selection regarding the operation conditions is an option. Systems included into the ageing management system will be specified in the paper. Also, the measures will be identified which serve as a check of implementation of all possible stressors and degradation mechanisms into the first screening. The examples of lifetime evaluation of some systems and components will be given in the paper: reactor pressure vessel, reactor internals, steam generator tubes and feedwater piping. Specific approaches will be shown fro different original status of components and different operation conditions. (author)

  6. Environmental emissions control programs at Lambton TGS [Thermal Generating Station

    International Nuclear Information System (INIS)

    Ontario Hydro's air emissions control programs at Lambton thermal generating station, both committed and planned, are reviewed, and their potential impacts on emissions, effluents and wastes are discussed. Control technologies examined include flue gas conditioning, wet limestone scrubbing, combustion process modifications, urea injection, and selective catalytic reduction. The implementation of these technologies has the potential to create new solid and liquid waste disposal problems, the full extent of which is often not realized at the process selection stage. For example, selective noncatalytic reduction using urea injection can lead to increased CO emissions, escape of unreacted ammonia from the stack at levels of 5-50 ppM, increase in N2O emissions, contamination of fly ash, gypsum and waste water with ammonia, and an increase in CO2 emissions of less than 0.4% due to increased power consumption. Optimum performance of the air emissions control systems, with minimum negative impact on the environment, requires consideration of the impact of these systems on all waste streams. 11 refs., 3 figs., 1 tab

  7. Ten years of German AF-program. Review and outlook at termination of the program

    International Nuclear Information System (INIS)

    After a decade of work by industry and national laboratories the German AF-Program will be closed at the end of 1989. The main goal to provide all means required to convert the research reactors in the Federal Republic of Germany has been reached. Conversion concepts meeting the essential criteria worked out by INFCE and all licensing and operating specific data have been elaborated so that the reactors in their present design will be either converted from HEU to LEU operation or closed after consumption of the available HEU material. There will be no future HEU requirements for these reactors. The program work was carried out within 15 major tasks (7 x fuel development and fabrication technology, 4 x fuel qualification, 4 conversion studies) 10 of which were handled by industry. The costs finally amount to 51.5 million German Marks (56% industry). Approximately 43 million German Marks were provided by the Federal Ministry for Research and Technology, the remainder largely was procured by industry. (orig.)

  8. The meson spectroscopy program with CLAS12 at Jefferson Laboratory

    Energy Technology Data Exchange (ETDEWEB)

    Rizzo, Alessandro [Univ. of Rome Tor Vergata (Italy)

    2016-06-01

    The study of the hadronic spectrum is one of the most powerful tools to investigate the mechanism at the basis of quark confinement within hadrons. A precise determination of the spectrum allows not only to assess the properties of the hadrons in their fundamental and excited states, but also to investigate the existence of states resulting from alternative configurations of quarks and gluons, such as the glue-balls, hybrid hadrons and many-quarks configurations. The study of the mesonic part of the spectrum can play a central role in this investigation thanks to the strong signature that the hybrid mesons are expected to have: the presence of explicit gluonic degrees of freedom in such states may result in JPC configurations not allowed for the standard q ¯ q states. From the experimental side the expected high-multiplicity decays of the hybrid mesons require an apparatus with high performances in terms of rate-capability, resolution and acceptance. The CLAS12 experiment (formally MesonEx) is one of new-generation experiments at Thomas Jefferson National Laboratory (JLAB) for which an unprecedented statistics of events, with fully reconstructed kinematics for large particle multiplicity decays, will be available. A wide scientific program that will start in 2016 has been deployed for meson spectrum investigation with the CLAS12 apparatus in Hall B at energies up to 11 GeV. One of the main parts of the program is based on the use of the Forward Tagger apparatus, which will allow CLAS12 experiment to extend the study of meson electro-production to the quasi-real photo-production kinematical region (very low Q2), where the production of hybrid mesons is expected to be favoured. The data analysis which is required to extract the signal from hybrid states should go beyond the standard partial wave analysis techniques and a new analysis framework is being set up through the international network Haspect. The Haspect Network gathers people involved into theoretical and

  9. A Teacher Professional Development Program for an Authentic Citizen-Science Program: GLOBE at Night

    Science.gov (United States)

    Walker, C. E.; Pompea, S. M.; Sparks, R.

    2009-12-01

    An authentic science research program in the classroom can take many forms as can the teacher professional development that accompanies the programs. One different approach invites educators to invoke 21st century skills with their students while focusing on a real-world issue of both local and global concern. The citizen-science program on light pollution, GLOBE at Night, has students and the general public measure the darkness of their local skies and contribute observations online to a world map. They do this by looking toward Orion for the faintest stars and matching what they see to one of seven different star maps. (For more precise measurements, digital sky-brightness meters are used.) These measurements can be compared with data from the previous 4 years, as well as with satellite data, population densities, and electrical power-usage maps. Measurements can be examined online via Google Earth or other tools and are downloadable as datasets from the website. Data from multiple locations in one city or region are especially interesting, and have been used as the basis of research in a classroom or science fair project or even to inform the development of public policy. This year, GLOBE at Night has been expanding its role in training educators on fundamental concepts and data collection to include more data analysis for a topical variety of local projects. Many on-site workshops have and are being given to teachers in grades 5 through high school. Some of the U.S. school communities created mini-campaigns that combined local students with public advocates and representatives from local city and county governments, and also collaborated with students in Wales, Canada, Romania and north-central Chile (near major observatories). Internationally, training has been given via on-line forums, telecon-powerpoint presentations, videoconferencing via Skype, and blogs. Informal educators have come from national and international networks of science, technology and

  14. Conceptual model of the hydrogeology of Sellafield

    International Nuclear Information System (INIS)

    Understanding the abundant data from site investigations at Sellafield is considerably aided by having a conceptual model of the groundwater flow system. It also forms the basis for numerical modelling. The idea of conceptual models is explained. In general, a conceptual model identifies the process or processes which cause groundwater movement together with the major limits and boundaries on those processes. The conceptual model for Sellafield is based on processes associated with the Irish Sea Basin competing with the present-day land-based freshwater system. The conceptual model is described in terms of three regimes: the Irish Sea Basin, the Coastal Plain, and the Hills and Basement. The Irish Sea Basin Regime is dominated by basinal processes and contains evaporite-derived brines. The Coastal Plain regime is a topographically driven system containing freshwater within transmissive sandstones. The Hills and Basement Regime is a transitional regime containing mixed brines and freshwater, driven by gravity near surface and in dynamic equilibrium at depth. Comparing the conceptual model against measured values of groundwater head and chemistry indicates broad agreement. Closer examination shows the value of understanding and measuring the interfaces between the regimes. Numerical modelling of the system is still at an early stage. (author)

    At PEP-II, seven large power supplies (LGPS) are used to power quad magnets in the electron-positron collider region. The LGPS ratings range from 72kW to 270kW, and were installed in 1997. They are unipolar off-line switch mode supplies, with a 6 pulse bridge rectifying 480VAC, 3-phase input power to yield 650VDC unregulated. This unregulated 650VDC is then input into one (or two) IGBT H-bridges, which convert the DC into PWM 16 kHz square wave AC. This high frequency AC drives the primary side of a step-down transformer followed by rectifiers and low pass filters. Over the years, these LGPS have presented many problems mainly in their control circuits, making it difficult to troubleshoot and affecting the overall accelerator availability. A redesign/rebuilding program for these power supplies was established under the coordination of the Power Conversion Department at SLAC. During the 2004 accelerator summer shutdown all the control circuits in these supplies were redesigned and replaced. A new PWM control b...

  16. Criticality experiments: analysis, evaluation, and programs. 7. Program of Experimental Investigations on Critical Facilities at IPPE

    International Nuclear Information System (INIS)

    In general, the BFS-1, BFS-2, MATR, and RF-GS critical facilities remain in operation at the Institute of Physics and Power Engineering (IPPE). BFS-1 and BFS-2 are universal facilities primarily intended for use with solid component elements; however, the license allows the use of water in central sub-zones. The BFS-1 and BFS-2 facilities are used for simulation of fast systems as well as systems with intermediate and thermal spectra. The MATR critical facility is intended for research of temperature effects on water-moderated cores over a wide range of temperatures (up to 250 deg. C) and pressures. The RF-GS critical facility is designed (with adaptable opportunities) for the simulation of multiplying systems with a water moderator. The experimental programs are being developed in the following directions: 1. use of plutonium released from the military programs as fuel for the BN and VVER reactors as well as for its immobilization in geological formations; 2. based on the perspective of the nuclear fuel cycle (in accordance with the initiative of the President of the Russian Federation), implemented in a new generation of fast reactors; 3. investigations of prospective reactors and accelerator-driven systems and creation of benchmarks for testing of calculational codes and neutron data for nontraditional materials. A considerable part of these investigations is being carried out in cooperation with foreign laboratories (United States, Japan, France, People's Republic of China, Republic of Korea, etc.). These programs are focused in three main directions. The first is concerned with the BN-600 reactor. Investigations into the use of a hybrid zone with this reactor have been carried out since 1999 and include the BFS-62-1 core (BN-600 initial state), BFS-62-2 (uranium core, steel reflector), BFS-62-3 (hybrid core, steel reflector), and BFS-62-4 (hybrid core, radial blanket). These experiments will be finished at the beginning of 2001 and are being carried out in

  17. Conceptual design of integrated safeguards systems

    International Nuclear Information System (INIS)

    The Los Alamos Scientific Laboratory (LASL) is currently involved in the conceptual design of safeguards for generic facilities in the back-end of the nuclear fuel cycle (spent-fuel reprocessing, plutonium nitrate-to-oxide conversion, mixed-oxide fuel fabrication, plutonium scrap recovery, and waste handling). These studies are first steps aimed at eventually providing detailed designs of integrated safeguards systems to guide safeguards-related facility construction and/or modification. The purpose of this presentation is to describe the conceptual design process in terms of its definition, a systematic procedure for its implementation, some of the tools required, and an example of the results of a conceptual design. The value of conceptual design and its relationship to other facets of the complete facility design process are also discussed

  2. PHENIX Conceptual Design Report

    International Nuclear Information System (INIS)

    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The eμ coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study π0 and η production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the φ meson (via K+K- decay), jets, and two-boson correlations. The measurements are made down to small cross sections to allow the study of high pT spectra, and J/ψ and Υ production. The PHENIX collaboration consists of over 300 scientists, engineers, and graduate students from 43 institutions in 10 countries. This large international collaboration is supported by US resources and significant foreign resources

  3. A kaon physics program at the Fermilab Main Injector

    International Nuclear Information System (INIS)

    In this paper we describe a triad of kaon experiments which will form the foundation of a kaon physics program at Fermilab in the Main Injector era. These three experiments; KAMI, CKM and CPT, span the range of experiment types discussed above. KAMI will use the existing neutral kaon beam and the KTeV detector as the basis of a search for the Standard Model ultra rare decay KL → π0ν anti ν decay mode is by far the theoretically cleanest measurement of the Standard Model parameter responsible for CP violation. CKM will measure the analogous charged kaon decay mode. Together these two experiments will determine the Standard Model contribution to CP violation independent of the B meson sector. The Standard Model parameters controlling CP violation must be observed to be the same in the K and B meson sectors in order to confirm the Standard Model as the sole source of CP violation in nature. CPT is a hybrid beam experiment using a high purity K+ beam to produce a pure K0 beam in order to search for violation of CPT symmetry at a mass scale up to the Planck mass. CPT also will measure new CP violation parameters to test the Standard Model and search for rare KS decays. The Fermilab infrastructure for such a physics program largely already exists. The Main Injector will be an existing accelerator by late 1998 with beam properties comparable to any of the previous ''kaon factory'' proposals. The KTeV detector and neutral kaon beamline are unsurpassed in the world and were originally designed to also operate with the 120 GeV Main Injector beam as KAMI. The Fermilab Meson laboratory was originally designed as an area for fixed target experiments using 200 GeV proton beams. The charged kaon beam experiments will naturally find a home there. Both charged kaon experiments, CKM and CPT, will share a new high purity RF separated charged kaon beam based on superconducting RF technology which will provide the highest intensity and purity charged kaon beam in the world

    International Nuclear Information System (INIS)

    In order to get enough beam current for each parallel beam line, the beam intensity distribution along aperture on the diaphragm is calculated to deduce a function which is verified by computer program for simulating charged particle beam transport systems, based on this function relationship between emittance of beam and the different aperture parameters on diaphragm is analyzed. At the end, a conceptual design of parallel beam line is given and the parameters of the optical elements are calculated. The results are accurate and credible. quality of beam can reach the requirements of user for nuclear physics experiments. (authors)

  9. Short-lived radionuclides program at the University of Michigan

    International Nuclear Information System (INIS)

    The University of Michigan Nuclear Medicine Research Program, from instrumentation design through radiopharmaceutical development to clinical evaluation, is heavily dependent on the availability and use of iodine-123. Research activities at the University of Michigan can be divided into four major areas: instrumentation, radiochemistry, radiopharmaceutical development, and clinical evaluation. In the first category a new single-photon ring tomograph (SPRINT) has been built and is undergoing performance testing. SPRINT has been designed specifically for brain imaging with 123I-labeled agents. In the area of radiochemistry, a simple radioiodide exchange technique has been developed for the rapid synthesis of 123I-labeled aromatic compounds. In the radiopharmaceutical arena, a new agent, 123I-meta-iodobenzyl-guanidine (MIBG), has been developed - the result of an extensive structure-distribution-relationship study. This radiopharmaceutical, a storage analog of norepinephrine, images organs with rich sympathetic innervation such as the heart and spleen. In the Nuclear Medicine Clinic three 123I-labeled radiopharmaceuticals are undergoing evaluation

  10. Low enrichment Mo-99 target development program at ANSTO

    International Nuclear Information System (INIS)

    The Australian Nuclear Science and Technology Organisation (ANSTO, formerly AAEC) has been producing fission product Mo-99 in HIFAR, from the irradiation of Low Enrichment Uranium (LEU) UO2 targets, for nearly thirty years. Over this period, the U-235 enrichment has been increased in stages, from natural to 1.8% to 2.2%. The decision to provide Australia with a replacement research reactor (RRR) for HIFAR has created an ideal opportunity to review and improve the current Mo-99 production process from target design through to chemical processing and waste management options. ANSTO has entered into a collaboration with Argonne National Laboratory (RERTR) to develop a target using uranium metal foil with U-235 enrichment of less than 20% The initial focus has been to demonstrate use of LEU foil targets in HIFAR, using existing irradiation methodology. The current effort focussed on designing a target assembly with optimised thermohydraulic characteristics to accommodate larger LEU foils to meet Mo-99 production needs. The ultimate goal is to produce an LEU target suitable for use in the Replacement Research Reactor when it is commissioned in 2005. This paper reports our activities on: - The regulatory approval processes required in order to undertake irradiation of this new target; -Supporting calculations (neutronics, computational fluid dynamics) for safety submission; - Design challenges and changes to prototype irradiation; - Trial irradiation of LEU foil target in HIFAR; - Future target and rig development program at ANSTO.

  11. Earthquake safety program at Lawrence Livermore National Laboratory

    International Nuclear Information System (INIS)

    Within three minutes on the morning of January 24, 1980, an earthquake and three aftershocks, with Richter magnitudes of 5.8, 5.1, 4.0, and 4.2, respectively, struck the Livermore Valley. Two days later, a Richter magnitude 5.4 earthquake occurred, which had its epicenter about 4 miles northwest of the Lawrence Livermore National Laboratory (LLNL). Although no one at the Lab was seriously injured, these earthquakes caused considerable damage and disruption. Masonry and concrete structures cracked and broke, trailers shifted and fell off their pedestals, office ceilings and overhead lighting fell, and bookcases overturned. The Laboratory was suddenly immersed in a site-wide program of repairing earthquake-damaged facilities, and protecting our many employees and the surrounding community from future earthquakes. Over the past five years, LLNL has spent approximately $10 million on its earthquake restoration effort for repairs and upgrades. The discussion in this paper centers upon the earthquake damage that occurred, the clean-up and restoration efforts, the seismic review of LLNL facilities, our site-specific seismic design criteria, computer-floor upgrades, ceiling-system upgrades, unique building seismic upgrades, geologic and seismologic studies, and seismic instrumentation. 10 references

    Resumption of transient testing at the TREAT facility was approved in February 2014 to meet U.S. Department of Energy (DOE) objectives. The National Nuclear Security Administration’s Global Threat Reduction Initiative Convert Program is evaluating conversion of TREAT from its existing highly enriched uranium (HEU) core to a new core containing low enriched uranium (LEU). This paper describes briefly the initial pre-conceptual designs screening decisions with more detailed discussions on current feasibility, qualification and fabrication approaches. Feasible fabrication will be shown for a LEU fuel element assembly that can meet TREAT design, performance, and safety requirements. The statement of feasibility recognizes that further development, analysis, and testing must be completed to refine the conceptual design. Engineering challenges such as cladding oxidation, high temperature material properties, and fuel block fabrication along with neutronics performance, will be highlighted. Preliminary engineering and supply chain evaluation provided confidence that the conceptual designs can be achieved.

  16. Waste Handling Building Conceptual Study

    International Nuclear Information System (INIS)

    The objective of the ''Waste Handling Building Conceptual Study'' is to develop proposed design requirements for the repository Waste Handling System in sufficient detail to allow the surface facility design to proceed to the License Application effort if the proposed requirements are approved by DOE. Proposed requirements were developed to further refine waste handling facility performance characteristics and design constraints with an emphasis on supporting modular construction, minimizing fuel inventory, and optimizing facility maintainability and dry handling operations. To meet this objective, this study attempts to provide an alternative design to the Site Recommendation design that is flexible, simple, reliable, and can be constructed in phases. The design concept will be input to the ''Modular Design/Construction and Operation Options Report'', which will address the overall program objectives and direction, including options and issues associated with transportation, the subsurface facility, and Total System Life Cycle Cost. This study (herein) is limited to the Waste Handling System and associated fuel staging system

    In 1980 Leon Lederman started Saturday Morning Physics with a handful of volunteer physicists, around 300 students and all the physics teachers who tagged along. Today Fermilab offers over 30 programs annually with help from 250 staff volunteers and 50 educators, and serves around 40,000 students and 2,500 teachers. Find out why we bother. Over the years we have learned to take advantage of opportunities and confront challenges to offer effective programs for teachers and students alike. We offer research experiences for secondary school teachers and high school students. We collaborate with educators to design and run programs that meet their needs and interests. Popular school programs include classroom presentations, experience-based field trips, and high school tours. Through our work in QuarkNet and I2U2, we make real particle physics data available to high school students in datadriven activities as well as masterclasses and e-Labs. Our professional development activities include a Teacher Resource Center and workshops where teachers participate in authentic learning experiences as their students would. We offer informal classes for kids and host events where children and adults enjoy the world of science. Our website hosts a wealth of online resources. Funded by the U.S. Department of Energy, the National Science Foundation and Fermilab Friends for Science Education, our programs reach out across Illinois, throughout the United States and even around the world. We will review the program portfolio and share comments from the volunteers and participants.

  18. The advanced controls program at Oak Ridge National Laboratory

    International Nuclear Information System (INIS)

    The Oak Ridge National Laboratory (ORNL), under sponsorship of the US Department of Energy (DOE), is conducting research that will lead to advanced, automated control of new liquid-metal-reactor (LMR) nuclear power plants. Although this program of research (entitled the ''Advanced Controls Program'') is focused on LMR technology, it will be capable of providing control design, test, and qualification capability for other advanced reactor designs (e.g., the advanced light water reactor [ALWR] and high temperature gas-cooled reactor [HTGR] designs), while also benefiting existing nuclear plants. The Program will also have applicability to complex, non-nuclear process control environments (e.g., petrochemical, aerospace, etc.). The Advanced Controls Program will support capabilities throughout the entire plant design life cycle, i.e., from the initial interactive first-principle dynamic model development for the process, systems, components, and instruments through advanced control room qualification. The current program involves five principal areas of research activities: (1) demonstrations of advanced control system designs, (2) development of an advanced controls design environment, (3) development of advanced control strategies, (4) research and development (R ampersand D) in human-system integration for advanced control system designs, and (5) testing and validation of advanced control system designs. Discussion of the research in these five areas forms the basis of this paper. Also included is a description of the research directions of the program. 8 refs

  19. Tomorrow's engineers through teacher/student programs at Penn State

    International Nuclear Information System (INIS)

    Interest in math and science increases when the problems and topics are current and socially relevant. A course that integrates various sciences requires a solid foundation in mathematics and an understanding that real life consists of an interaction of the basic sciences. One topical area that requires the understanding of math and science and affects our society is radiation. Although nuclear issues are prevalent in the news, very few secondary science educators receive much formal training in radiation and nuclear science. A strong push for educational programs on this topic by the U.S. Atomic Energy Commission and state departments of education began in the late 1960s and early 1970s. Through this effort, Pennsylvania State University (Penn State) developed the Nuclear Concepts Institute for secondary science teachers and has continued its involvement with educational programs in nuclear science for teachers and students. From discussions with teachers and students along with formal and informal surveys, the programs have had a positive impact on teachers' interest in learning more about nuclear science and on students' choices to enter nuclear engineering or a related field. The paper discusses the Nuclear Concepts Program; formation of the American Nuclear Science Teachers Association (ANSTA); ANSTA projects; other Penn State educational programs; and impact of education programs

    Full Text Available Educators at Sograndio Juvenile Detention Center in Asturias were sure that they were able to offer new alternatives to improve their socio-educational intervention. That is the reason why they got involved in an action research training process aimed at making didactic proposals which tried to optimize the development of social competence programs for youngsters with criminal behavior. In order to do this, the Short Version of the Prosocial Thinking Program for Young People (Alba et al., 2005 was applied to nine inmates, eight males between 14 and 20 years old and a female of 16 years old. Theywere the basis and reflection of ourmethodological intervention. The teamtaking part in this intervention is formed by nine inmates and three external members (two coordinators and a woman psychologist. The investigation, mainly qualitative, includes different instruments (both qualitative and quantitative, such as: observation registries, discussion groups, questionnaires and notebooks. After the implementation of the program, positive changes must be highlighted in the emotional dimension, the resolution of problems, self-control and frustration tolerance. Besides, very high levels of satisfaction have been observed among youngsters, educators and external informants. It is important to have created a climate of professional compromise towards change and this way to have abandoned a passive attitude towards training, so that we were able to start an active search for practical answers, adjusted to our necessities and professional interests. Finally, we make several observations and intervention proposals that contribute to generate didactic knowledge thought and adapted for social education.

    2011-05-01

    We discuss the results on the fundamental degrees of freedom underlying the nucleon excitation spectrum and how they evolve as the resonance transitions are investigated with increasingly better space-time resolution of the electromagnetic probe. Improved photocouplings for a number of resonant states, those for the N(1720)P13 being significantly changed, have been determined and entered into the 2008 edition of the RPP. Strong sensitivity to the N(1900)P13 state, listed now as a 2-star state in the same edition of RPP, has been observed in KΛ and KΣ photoproduction. None of the earlier observations of a Θ+5(1540) was confirmed in a series of three Jefferson Lab high statistics dedicated measurements, and stringent upper limits on production cross sections were placed in several channels. For the four lowest excited states, the Δ(1232)P33, N(1440)P11, N(1520)D13, and N(1535)S11, the transition amplitudes have been measured in a wide range in photon virtuality Q2. The amplitudes for the Δ(1232) show the importance of the pion-cloud contribution and do not show any sign of approaching the pQCD regime for Q2 photo- and electroproduction data allowed one to specify the branching ratios of this state to the πN and ηN channels; they entered into the 2010 edition of the RPP. Measured for the first time, the longitudinal transition amplitude for the N(1535)S11 became a challenge for quark models and can be indicative of large meson-cloud contributions or alternative representations of this state. The N(1520)D13 clearly shows the rapid changeover from helicity-3/2 dominance at the real photon point to helicity-1/2 dominance at Q2 > 0.5 GeV2 confirming a long-standing prediction of the constituent quark model. The search for undiscovered but predicted states continues to be pursued with a vigorous experimental program. While recent data from Jefferson Lab and elsewhere provide intriguing hints of new states, final conclusions will have to wait for the results of the

    International Nuclear Information System (INIS)

    Thermal-hydraulics, Hydrogen, Aerosol and Iodine (Thai) aims at providing experimental database for the verification and validation of Lumped Parameter (Lp) and Computational Fluid Dynamics (CFD) codes with 3-dimensional capabilities. Since its construction in 2000, Thai facility has been engaged in the field of reactor safety in the frame of various national (Thai I: 2000-2003, Thai II: 2003-2006, Thai III: 2006-2009, Thai IV: 2009-2012) and international programs (OECD-Thai: 2007-2009). Additionally, experimental data has been provided for several international standard problems (ISP 41, 46, 47 and 49) code validation exercises. Experiments performed in Thai facility cover a wide spectrum or reactor safety relevant issues by investigating separate and coupled-phenomenon experiments under design basis accident and severe-accident-typical scenarios. Experiments are performed in close co-operation with AREVA Erlangen and Grs Koln. Experimental configuration and the operating conditions in Thai vessel typical of those for PWR, BWR and High Temperature Gas Cooled Reactor can be produced thanks to its modular structure, appropriate feeding/generation devices for gases (H2, He, Steam, N2, etc.), Aerosol (inert and hygroscopic), Iodine Radiotracer, and advanced instrumentation. Experiments also cover investigation of passive safety systems, e.g. commercial Par for H2 mitigation in phenomenon orientated experiments to enhance the confidence in the performance of passive mitigation systems during severe accident scenarios and also to establish a common database accessible by a large research community to support further development and validation of the Lp and CFD codes with 3-dimensional capabilities. This paper summarizes experimental investigations made in Thai test facility to investigate issues related to the thermal-hydraulics, fission product (aerosol, iodine) transport and their interaction with containment walls (deposition, resuspension) and passive safety

    After approving the waste certification programs for 45 generators of low-level radioactive and mixed waste, Westinghouse Savannah River Company (WSRC) moved forward to implement a performance-based approach for assuring that approved waste generators maintain their waste certification programs. WSRC implemented the Waste Certification Review Program, which is comprised of two sitewide programs, waste generator self-assessments and Facility Evaluation Board reviews, integrated with the WSRC Solid Waste Management Department Waste Verification Program Evaluations. The waste generator self-assessments ensure compliance with waste certification requirements, and Facility Evaluation Board reviews provide independent oversight of generators' waste certification programs. Waste verification evaluations by the TSD facilities serve as the foundation of the program by confirming that waste contents and generator performance continue to meet waste acceptance criteria (WSRC 1994) prior to shipment to treatment, storage, and disposal facilities. Construction of the Savannah River Site (SRS) was started by the US Government in 1950. The site covers approximately 300 square miles located along the Savannah River near Aiken, South Carolina. It is operated by the US Department of Energy (DOE). Operations are conducted by managing and operating contractors, including the Westinghouse Savannah River Company (WSRC). Historically, the primary purpose of the SRS was to produce special nuclear materials, primarily plutonium and tritium. In general, low-level radioactive and mixed waste is generated through activities in operations. Presently, 47 SRS facilities generate low-level radioactive and mixed waste. The policies, guidelines, and requirements for managing these wastes are determined by DOE and are reflected in DOE Order 5820.2A (US DOE 1988)

  7. The power professorship program at Washington State University

    International Nuclear Information System (INIS)

    As with most electric power programs, Washington State University's has existed since the beginning of the engineering program 100 years ago. It has grown and developed largely through the efforts of a few dedicated individuals. The Power Professorship Program has existed since 1972. The Power Professor has been Dr. Clifford C. Mosher until his recent semi-retirement. The Power Professorship was conceived of as an avenue for joint university-industry interaction. Considerable time and ingenuity by visionary engineers and others have resulted in development of a financial base for the Power Professorship Program. The program has been funded equally by public and investor-utility sectors. Following financial difficulties stemming from the Washington Public Power Supply System financial default on public utility bonds for several nuclear projects, funding for the program from the public sector was canceled. After several lean years, public-sector support was again restored by WSU's electrical engineering department offering a contract for services to the utilities in exchange for funding. This contract has been renewed annually, with costs and benefits firmly established through careful analysis and consultation. Problems facing the power industry in the early 1970s with regard to establishing a pipeline of future human resources, were almost identical with those of the present time: indifferent feelings about the industry in general, students being attracted to more glamorous disciplines, and a decline in educational opportunities available in the power area. A 1985 article in the IEEE Power Engineering Review describing today's declining enrollment in power engineering applies equally well to previous periods. A major driving force for initiating utility-industry participation in the Power Professorship Program was the concern for maintaining a source of entry-level engineers with a background in power engineering

  17. What factors have influenced implementation of the Developmental Approaches in Science, Health and Technology program at two elementary schools on O'ahu, Hawai'i?

    Science.gov (United States)

    Carson, Lani L.

    This dissertation is a report of two hypothesis-generating qualitative case studies that investigated the factors that affected the successful school-wide implementation of the Developmental Approaches in Science, Health and Technology program, a spiraling, integrated, hands-on program for grades Kindergarten to 6 at two public elementary schools on the island of Oahu, in the state of Hawaii. Four key people were interviewed, 47 classrooms were observed three times each, and 41 of 48 teacher surveys were completed. An author-generated flow-of-influences conceptual framework based on other research findings about variables influencing the implementation of a curricular innovation delineates curricular, organizational, and external variables along with possible teacher-perceived outcomes. The results include 42 tables and 44 figures showing the many factors' positive and negative impacts on the schools' reform efforts. Eighteen hypotheses were generated. Well-planned implementations, strong administrative support and leadership, sustained follow-up support, and frequent collegial planning and sharing times seemed to have the greatest positive influences upon teacher confidence regarding program knowledge and sustained program use. More tenured teachers were using the program at levels equal to or greater than newer teachers until around twenty years of teaching experience, when there was a marked decline in program use.

    2002-11-01

    Acoustics, essentially a multidisciplinary subject, still has in Brazil a small but increasing number of professionals with a solid background to deal with various aspects of this area. Since 1970 the faculty of the Acoustics and Vibration Laboratory, COPPE/UFRJ, offers graduate (M.Sc and D.Sc) programs, and some undergraduate courses in acoustics, vibration, and signal processing. In January 2000, this group launched a formal undergraduate engineering acoustics program in the Mechanical Engineering Department of the Federal University of Rio de Janeiro. After three years of mechanical engineering, with a firm foundation in physics, applied mathematics, and engineering basics, the undergraduate student may elect to take the engineering acoustics program for the remaining two years. In this program, a wide number of courses are offered, including basic acoustics, room acoustics, signal processing, musical acoustics, machine diagnosis, etc. Approximately 30 different courses may be chosen from. However, the student is not completely free, since the courses selected must fit within a subject concentration profile, e.g., noise control or musical acoustics. In this paper the programs curriculum are presented and its impact on the students is discussed. A first evaluation of the qualifications achieved by the graduate students in the area is also presented.

    The Graduate K-12 (GK12) program has been developed by NSF to support the national effort to advance scientific knowledge through educational partnerships. This paper highlights research conducted during the 2006-2007 school year with the Texas A&M University GK12 project. Two elementary schools with very high numbers of at risk students - those who are poor, speak English as their second language, and have a history of failing state-mandated tests were identified to be the field site for the GK12 project. In these two, high-minority (97% and 40% African American and Hispanic) schools, 80% and 56% of the children have been identified by the state as at risk; 94% and 52% are classified as economically disadvantaged; and 46% and 2% are limited English proficient, respectively. In the past year, 30% and 73% of fifth grade students in these schools passed the science portion of the Texas Assessment of Knowledge and Skills (TAKS) test. Data collected during a three- week period where GK12 fellows taught the fifth graders Earth science-related topics is presented. During the implementation, students were engaged in technology-, inquiry-, and game-based activities. Students were divided into low-, medium-, and high-abilities in one school, and regular and bilingual groups in the other. Pre- post open-ended multiple choice tests indicated that all but the low performing students' conceptual understanding (CU) significantly (p game activities. Classroom observation assessments showed that there was a significant (p technology-based activities showed greatest differences between the low- ability learners and the other students, whereas, inquiry-based activities tended not to show such extremes. In the case of the bilingual and regular students however, technology-based instruction tended to increase their scores and decrease gaps with other groups. Using different pedagogical approaches (e.g., technology-, inquiry- and game-based methods) to teach Earth science is important

    2015-01-01

    Maximizing reader insights into interior design as a conceptual way of thinking, which is about ideas and how they are formulated. The major themes of this book are the seven concepts of planning, circulation, 3D, construction, materials, colour and lighting, which covers the entire spectrum of a designer’s activity. Analysing design concepts from the view of the range of possibilities that the designer can examine and eventually decide by choice and conclusive belief the appropriate course of action to take in forming that particular concept, the formation and implementation of these concepts is taken in this book to aid the designer in his/her professional task of completing a design proposal to the client. The purpose of this book is to prepare designers to focus on each concept independently as much as possible, whilst acknowledging relative connections without unwarranted influences unfairly dictating a conceptual bias, and is about that part of the design process called conceptual analysis.

  3. PRA and Conceptual Design

    DeMott, Diana; Fuqua, Bryan; Wilson, Paul

    2013-01-01

    Once a project obtains approval, decision makers have to consider a variety of alternative paths for completing the project and meeting the project objectives. How decisions are made involves a variety of elements including: cost, experience, current technology, ideologies, politics, future needs and desires, capabilities, manpower, timing, available information, and for many ventures management needs to assess the elements of risk versus reward. The use of high level Probabilistic Risk Assessment (PRA) Models during conceptual design phases provides management with additional information during the decision making process regarding the risk potential for proposed operations and design prototypes. The methodology can be used as a tool to: 1) allow trade studies to compare alternatives based on risk, 2) determine which elements (equipment, process or operational parameters) drives the risk, and 3) provide information to mitigate or eliminate risks early in the conceptual design to lower costs. Creating system models using conceptual design proposals and generic key systems based on what is known today can provide an understanding of the magnitudes of proposed systems and operational risks and facilitates trade study comparisons early in the decision making process. Identifying the "best" way to achieve the desired results is difficult, and generally occurs based on limited information. PRA provides a tool for decision makers to explore how some decisions will affect risk before the project is committed to that path, which can ultimately save time and money.

  4. Surveillance program and aging management at ETRR-II

    International Nuclear Information System (INIS)

    Surveillance program, periodic testing, and in-service inspection are tools to manage the aging of the research reactors and keep the operation of the research reactors within its design, safety analysis, and operational limits and conditions (OLC's) for the lifetime of the research reactor. This paper describes the surveillance program and aging management of the most important systems, structures, and components (SSC's) of the second research reactor of Egypt (ETRR-II). We believe that the exchange of information and discussion between the members states, about this topic, can lead to the best practice for the research reactor surveillance and aging management. It is important for the members states to try to find benchmarking measures for this topic to make the aging management and surveillance program measurable and achievable. (author)

    2012-04-01

    Full Text Available The purpose of this study was to investigate how the use of the computer simulations program VPython facilitated students’ conceptual understanding of fundamental physical principles and in constructing new knowledge of physics. We focused on students in a calculus-based introductory physics course, based on the Matter and Interactions curriculum of Chabay & Sherwood (2002 at a large state engineering and science university in the USA. A major emphasis of this course was on computer modeling by using VPython to write pro¬grams simulating physical systems. We conducted multiple student interviews, as well as an open-ended exit survey, to find out student views on how creating their own simulations to enhanced-conceptual understanding of physics and in constructing new knowledge of phys¬ics. The results varied in relation to the phases when the interviews were conducted. At the beginning of the course, students viewed the simulation program as a burden. However, dur¬ing the course, students stated that it promoted their knowledge and better conceptual understanding of physical phenomena. We deduce that VPython computer simulations can improve students’ conceptual understanding of fundamental physical concepts and promote construction of new knowledge in physics, once they overcome the initial learning curve associated with the VPython software package.

  15. Steam generator deposit control program assessment at Comanche Peak

    International Nuclear Information System (INIS)

    Comanche Peak has employed a variety of methods to assess the effectiveness of the deposit control program. These include typical methods such as an extensive visual inspection program and detailed corrosion product analysis and trending. In addition, a recently pioneered technique, low frequency eddy current profile analysis (LFEC) has been utilized. LFEC provides a visual mapping of the magnetite deposit profile of the steam generator. Analysis of the LFEC results not only provides general area deposition rates, but can also provide local deposition patterns, which is indicative of steam generator performance. Other techniques utilized include trending of steam pressure, steam generator hideout-return, and flow assisted corrosion (FAC) results. The sum of this information provides a comprehensive assessment of the deposit control program effectiveness and the condition of the steam generator. It also provides important diagnostic and predictive information relative to steam generator life management and mitigative strategies, such as special cleaning procedures. This paper discusses the techniques employed by Comanche Peak Chemistry to monitor the effectiveness of the deposit control program and describes how this information is used in strategic planning.

  19. Investment recovery program at Niagara Mohawk Power Corporation

    International Nuclear Information System (INIS)

    Niagara Mohawk Power Company's pioneering investment recovery program was initiated in 1984, Its mission is to dispose of company assets classified as obsolete, scrap, surplus, or retired capital equipment that results from company operations or work projects. These assets include items such as scrap wire, pipe, line hardware, transformers, power station equipment, crates of dusty telephone modems and computer monitors, pallets of residential gas and electric meters, a box of toilet paper holders, burned-out light bulbs, chunks of electric cable, brass and copper valves, electric bills from 1952, and a dozen tattered office chairs. It was risky for Niagara Mohawk to commit money to a program that created a scrap company inside a utility and is not the core business. No one regrets the decision to create and expand investment recovery. The program has contributed more than $35,000,000 ($8,140,585 nuclear division) of cash receipts with an additional $5,000,000 of cost avoidance since its inception. The program has credited these dollars back to the operating departments, which has reduced operating costs thereby improving the open-quotes bottom line.close quotes

  20. High energy physics program at Texas A ampersand M University

    International Nuclear Information System (INIS)

    The Texas A ampersand M high energy physics program has achieved significant mile-stones in each of its research initiatives. We are participating in two major operating experiments, CDF and MACRO; the development of two new detector technologies, liquid scintillating fiber calorimetry and knife-edge chambers; and two SSC detector proposals, SDC and TEXAS/EMPACT. We have developed prototypes of a liquid-scintillator fiber calorimeter system, in which internally reflecting channels are imbedded in a lead matrix and filled with liquid scintillator. This approach combines the performance features of fiber calorimetry and the radiation hardness of liquid scintillator, and is being developed for forward calorimetry in TEXAS/EMPACT. A new element in this program is the inclusion of a theoretical high energy physics research program being carried out by D. Nanopoulos and C. Pope. D. Nanopoulos has succeeded in building a string-derived model that unifies all known interactions: flipped SU(5), which is the leading candidate for a TOE. The impact of this work on string phenomenology certainly has far reaching consequences. C. Pope is currently working on some generalizations of the symmetries of string theory, known as W algebras. These are expected to have applications in two- dimensional conformal field theory, two-dimensional extensions of gravity and topological gravity, and W-string theory. The following report presents details of the accomplishments of the Texas A ampersand M program over the past year and the proposed plan of research for the coming year
