  1. Containment performance assessment through hydraulic testing - Baltimore works site with comparison

    International Nuclear Information System (INIS)

    The Baltimore Works site containment consists of a circumferential vertical barrier, multimedia cap, and active intragradient conditions predicated upon low leakage and minimal groundwater extraction through time. The soil-bentonite barrier, keyed into decomposed bedrock, measures 3300 linear feet (1006 m) by 3 feet (0.91 m) thick with a depth ranging from 65-80 feet (19.8-24.4 m). Interior groundwater extraction wells equipped with pumps and controls are dynamically actuated by continuously monitored water levels from paired piezometers spaced every 280 linear feet (85.4 m) around the barrier perimeter. To confirm barrier performance and adequate distance-drawdown response, the containment was rigorously tested and monitored. Detailed pre-design investigations and construction quality assurance (CQA) provided a confidently constructed barrier. Further monitoring and testing to prove the containment's performance prior to construction included tidal monitoring, slug and pump testing, site-wide drawdown testing, and groundwater/surface water quality monitoring. This paper discusses the barrier specifics and details of the performance testing. The test data is presented to support the performance assessment. Testing methods are discussed and compared to other industry examples where hydraulic testing was used in performance assessment. Finally, some recommendations for further industry testing are discussed

    Maryland (MD) recently became one of fourteen states in the United States to enact a traffic law requiring motor vehicles to pass bicyclists at a distance of greater than three feet. To our knowledge, motorist compliance with the law has never been assessed. This study measured the distance between overtaking motor vehicles and cyclists [e.g. vehicle passing distance (VPD)], to develop baseline metrics for tracking implementation of the three-foot passing law in Baltimore, MD and to assess risk factors for dangerous passes. During September and October 2011, cyclists (n=5) measured VPD using a previously published video technique (Parkin and Meyers, 2010). Cyclists logged a total of 10.8h of video footage and 586 vehicle passes on 34 bicycle commuting trips. The average trip lasted 19.5±4.9 min and cyclists were passed on average 17.2±11.8 times per trip. VPDs of three feet or less were common when cycling in standard lanes (17%; 78 of 451 passes) and lanes with a shared lane marking (e.g. sharrows) (23%; 11 of 47 passes). No passes of three feet or less occurred in bicycle lanes (0 of 88 passes). A multiple linear regression model was created, which explained 26% of the variability in VPD. Significant model variables were lane width, bicycle infrastructure, cyclist identity, and street identity. Interventions, such as driver education, signage, enforcement, and bicycle infrastructure changes are needed to influence driving behavior in Baltimore to increase motorist compliance with the three-foot law.

  3. Results of the indoor radiological survey at the W.R. Grace Co., Curtis Bay site, Baltimore, Maryland

    International Nuclear Information System (INIS)

    The W.R. Grace Company, Davison Chemical Division, conducted developmental research and extraction of thorium from monazite ore at its Curtis Bay facility in Baltimore, Maryland, during the 1950s under contract to the Atomic Energy Commission (AEC). Only one of the numerous buildings on the site was used for these operations. A 1979 aerial survey of the site for the Department of Energy (DOE) indicated that a comprehensive ground survey was required to determine whether or not any contamination remained from the AEC activities in that building. A radiological scoping survey performed later that year for DOE by a team from the Measurement Applications and Development Group of the Health and Safety Research Division, Oak Ridge National Laboratory (ORNL), disclosed surface contamination (alpha) levels in excess of DOE criteria on all five levels of the building. As a result of this finding, two additional surveys were performed in 1986 by ORNL at the request of DOE to evaluate any present or potential health risk. They are detailed in this report. The results of the 1986 surveys revealed several areas having elevated levels of radiation as a result of significant quantities of thorium on some building surfaces such as floors and ceiling beams. Most areas were small spots and in locations of low occupancy; thus, the possibility for significant exposure to workers was judged to be low. To confirm this evaluation, annual radiation exposure estimates for workers frequenting the few, larger contaminated areas on the site were derived using ORNL survey data and occupancy factors provided by the W.R. Grace Company. Estimates ranged from 27 to 41 mrem/yr or a maximum of 41% of the basic dose limit of 100 mrem/yr for members of the general public. 2 refs., 14 figs., 8 tabs

    The Gulf of Mexico and Louisiana continue to be areas with a high level of facility removal, and the pace of removal is projected to increase. Regulations were promulgated for the Gulf of Mexico and Louisiana requiring that abandoned sites be cleared of debris that could interfere with fishing and shrimping activities. The site clearance regulations also required verification that the sites were clear. Additionally, government programs were established to compensate fishermen for losses associated with snagging their equipment on oil and gas related objects that remained on the water bottoms in areas other than active producing sites and sites that had been verified as clear of obstructions and snags. The oil and gas industry funds the compensation programs. This paper reviews the regulations and evolving operating practices in the Gulf of Mexico and Louisiana where site clearance and fisherman`s gear compensation regulations have been in place for a number of years. Although regulations and guidelines may be in place elsewhere in the world, this paper focuses on the Gulf of Mexico and Louisiana. Workshop participants are encouraged to bring up international issues during the course of the workshop. Additionally, this paper raises questions and focuses on issues that are of concern to the various Gulf of Mexico and Louisiana water surface and water bottom stakeholders. This paper does not have answers to the questions or issues. During the workshop participants will debate the questions and issues in an attempt to develop consensus opinions and/or make suggestions that can be provided to the appropriate organizations, both private and government, for possible future research or policy adjustments. Site clearance and facility removal are different activities. Facility removal deals with removal of the structures used to produce oil and gas including platforms, wells, casing, piles, pipelines, well protection structures, etc.

    Santelli, J S; Birn, A E; Linde, J

    1992-05-01

    Over the past 6 years, the city of Baltimore has successfully implemented a school placement policy for human immunodeficiency virus (HIV)-infected children and children with acquired immunodeficiency syndrome (AIDS). Both policy and specific procedures are based on nationally promulgated guidelines. School placement policy is part of an overall AIDS policy that includes education of students and staff and adoption of universal precautions to prevent transmission of communicable diseases in school. Implementation has been marked by excellent collaboration between the departments of health and education. Important policy components include expedited clinical investigation of each case, an interagency review panel, strict protection of confidentiality, a restricted setting for certain children, a school site visit for each placement, and continued monitoring of the school placement by school nurses. Many HIV-infected students need special educational services and/or school health services. The Baltimore City school placement process has avoided the exaggerated publicity endured by some communities, where media reporting has aggravated community fears and invaded the lives of families with HIV-infected children. Baltimore City has succeeded in ensuring access to education, protecting families' confidentiality, and providing special care for HIV-infected students. Local communities should emphasize national guidelines in designing school placement policies for HIV-infected children. School placement policies work best in the context of a comprehensive policy incorporating AIDS education and care. PMID:1579392

  16. Working together with regulators on nuclear sites

    International Nuclear Information System (INIS)

    A scheme for earlier and clearer communications with the Health and Safety Executive (HSE) and the Environment Agency (EA) on jointly regulated issues has been developed across the nuclear industry over the past two years. The matched pair of industry and regulators' 'Working Together' documents was published in January 2003. In the United Kingdom Atomic Energy Authority (UKAEA), the scheme is being put into practice through the issue of Initial Regulatory Notifications (IRN) of various projects and issues, to capture key regulatory topics and prompt regulators' initial responses. The IRN may be based on a safety and environment overview report or may be a precursor to it. Positive responses, in line with the Working Together documents, were received from HSE and the EA, following receipt of the first three UKAEA IRNs. (author)

    The Baltimore Air Toxics Study is one of the three urban air toxics initiatives funded by EPA to support the development of the national air toxics strategy. As part of this project, the Air Quality Integrated Management System (AIMS) is under development. AIMS is designed to bring together the key components of urban air quality management into an integrated system, including emissions assessment, air quality modeling, and air quality monitoring. Urban area source emissions are computed for a wide range of pollutants and source categories, and are joined with existing point source emissions data. Measured air quality data are used to evaluate the adequacy of the emissions data and model treatments as a function of season, meteorological parameters, and daytime/nighttime conditions. Based on tested model performance, AIMS provides the potential to improve the ability to predict air quality benefits of alternative control options for criteria and toxic air pollutants. This paper describes the methods used to develop AIMS, and provides examples from its application in the Baltimore metropolitan area. The use of AIMS in the future to enhance environmental management of major industrial facilities also will be addressed in the paper.

  1. Receptor modeling for multiple time resolved species: The Baltimore supersite

    Science.gov (United States)

    Ogulei, David; Hopke, Philip K.; Zhou, Liming; Paatero, Pentti; Park, Seung Shik; Ondov, John M.

    A number of advances have been made toward solving receptor modeling problems using advanced factor analysis methods. Most recently, a factor analysis method has been developed for source apportionment utilizing aerosol compositional data with varying temporal resolution. The data used in that study had time resolutions ranged from 10 min to 1 h. In this work, this expanded model is tested using a data set from the Ponca Street site of the Baltimore supersite with time resolutions ranging from 30 min to 24 h. The nature of this data set implies that traditional eigenvalue-based methods cannot adequately resolve source factors for the atmospheric situation under consideration. Also, valuable temporal information is lost if one averaged or interpolated data in an attempt to produce a data set of the identical time resolution. Each data point has been used in its original time schedule and the source contributions were averaged to correspond to the specific sampling time interval. A weighting coefficient, w24, was incorporated in the modeling equations in order to improve data fitting for the 24-h data in the model. A total of nine sources were resolved: oil-fired power plant (2%), diesel emissions (1%), secondary sulfate (23%), coal-fired power plant (3%), incinerator (9%), steel plant (12%), aged sea salt (1%), secondary nitrate (23%), and spark-ignition emissions (26%). The results showed the very strong influence of the adjacent interstate highways I-95 and I-895 as well as the tunnel toll booths located to the south of the sampling site. Most of the sulfate observed was found to be associated with distant coal-fired power plants situated in the heavily industrialized midwestern parts of the United States. The contribution of the steel plant (<10 miles, 141°SE) to the observed PM concentrations (12%) was also significant.

    The research findings fill a gap in the body of knowledge by presenting an effective way to evaluate the significance of on-site environmental impacts of municipal engineering works prior to the construction stage. First, 42 on-site environmental impacts of municipal engineering works were identified by means of a process-oriented approach. Then, 46 indicators and their corresponding significance limits were determined on the basis of a statistical analysis of 25 new-build and remodelling municipal engineering projects. In order to ensure the objectivity of the assessment process, direct and indirect indicators were always based on quantitative data from the municipal engineering project documents. Finally, two case studies were analysed and found to illustrate the practical use of the proposed model. The model highlights the significant environmental impacts of a particular municipal engineering project prior to the construction stage. Consequently, preventive actions can be planned and implemented during on-site activities. The results of the model also allow a comparison of proposed municipal engineering projects and alternatives with respect to the overall on-site environmental impact and the absolute importance of a particular environmental aspect. These findings are useful within the framework of the environmental impact assessment process, as they help to improve the identification and evaluation of on-site environmental aspects of municipal engineering works. The findings may also be of use to construction companies that are willing to implement an environmental management system or simply wish to improve on-site environmental performance in municipal engineering projects. -- Highlights: • We present a model to predict the environmental impacts of municipal engineering works. • It highlights significant on-site environmental impacts prior to the construction stage. • Findings are useful within the environmental impact assessment process. • They also

    2000-12-14

    Project Gasbuggy was the first of three joint government-industry experiments conducted to test the effectiveness of nuclear explosives to fracture deeply buried, low-permeability natural gas reservoirs to stimulate production. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the Project Gasbuggy Site. Its goal is the collection of data in sufficient quantity and quality to determine current site conditions, support a risk assessment for the site surfaces, and evaluate if further remedial action is required to achieve permanent closure of the site that is both protective of human health and the environment. The Gasbuggy Site is located approximately 55 air miles east of Farmington, New Mexico, in Rio Arriba County within the Carson National Forest in the northeast portion of the San Juan Basin. Historically, Project Gasbuggy consisted of the joint government-industry detonation of a nuclear device on December 10, 1967, followed by reentry drilling and gas production testing and project evaluation activities in post-detonation operations from 1967 to 1976. Based on historical documentation, no chemical release sites other than the mud pits were identified; additionally, there was no material buried at the Gasbuggy Site other than drilling fluids and construction debris. Although previous characterization and restoration activities including sensitive species surveys, cultural resources surveys, surface geophysical surveys, and limited soil sampling and analysis were performed in 1978 and again in 2000, no formal closure of the site was achieved. Also, these efforts did not adequately address the site's potential for chemical contamination at the surface/shallow subsurface ground levels or the subsurface hazards for potential migration outside of the current site subsurface intrusion restrictions.

AIDS work-site programs were mainly initiated by the four study companies as a result of the efforts of a champion (defined as an individual who gains attention and resources for an issue in a system) or the occurrence of a tragic event, such as a company employee contracting AIDS. The BRTA program is an innovation that has not yet reached critical mass, which is the point after which further rates of adoption occur rapidly in a self-sustaining process. PMID:10947372

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) has prepared this initial site observational work plan (SOWP) for the Uranium Mill Tailings Remedial Action (UMTRA) Project site in Grand Junction, Colorado. This SOWP is one of the first UMTRA Ground Water Project documents developed to select a compliance strategy that meets the UMTRA ground water standards (40 CFR Part 192, as amended by 60 FR 2854) for the Grand Junction site. This SOWP applies information about the Grand Junction site to the compliance strategy selection framework developed in the UMTRA Ground Water Project draft programmatic environmental impact statement (PEIS).

  19. Site characterization and the method of multiple working hypotheses

    International Nuclear Information System (INIS)

    Geologic investigations are necessary to determine whether a site is suitable for repository development and, if suitable, whether the site complies with regulatory requirements. Geologic processes and events often cannot be characterized without some degree of residual uncertainty. The method of multiple working hypotheses (MWH) is an approach in which alternative explanations for natural processes and/or events are identified, tested, and evaluated. This paper reports that in practice, several hypotheses may remain viable after all reasonable studies have been completed. Within the context of waste management and civil construction projects, all viable hypotheses that correspond with potential natural hazards must be analyzed in terms of adverse consequences to public health and safety, including radiological safety. For the repository licensing process, viable hypotheses remaining after the evaluation of data and quantification of uncertainty must be analyzed with regard to their consequences related to waste isolation. This approach can be used to determine whether additional studies are necessary to complete the license application

    In 1998, carbon tetrachloride was found above the maximum contaminant level (MCL) of 5 {micro}g/L in groundwater from one private livestock well at Sylvan Grove, Kansas, by the Kansas Department of Health and Environment (KDHE). The 1998 KDHE sampling was conducted under the U.S. Department of Agriculture (USDA) private well sampling program. The Commodity Credit Corporation (CCC), a USDA agency, operated a grain storage facility in Sylvan Grove from 1954 to1966. Carbon tetrachloride is the contaminant of primary concern at sites associated with former CCC/USDA grain storage operations. Sylvan Grove is located in western Lincoln County, approximately 60 mi west of Salina (Figure 1.1). To determine whether the former CCC/USDA facility at Sylvan Grove is a potential contaminant source and its possible relationship to the contamination in groundwater, the CCC/USDA has agreed to conduct an investigation, in accordance with the Intergovernmental Agreement between the KDHE and the Farm Service Agency (FSA) of the USDA. This Work Plan presents historical data related to previous investigations, grain storage operations, local private wells and public water supply (PWS) wells, and local geologic and hydrogeologic conditions at Sylvan Grove. The findings from a review of all available documents are discussed in Section 2. On the basis of the analyses of historical data, the following specific technical objectives are proposed for the site investigation at Sylvan Grove: (1) Evaluate the potential source of carbon tetrachloride at the former CCC/USDA facility; (2) Determine the relationship of potential contamination (if present) at the former CCC/USDA facility to contamination identified in 1998 in groundwater samples from one private well to the west; and (3) Delineate the extent of potential contamination associated with the former CCC/USDA facility. The detailed scope of work is outlined in Section 3. The results of the proposed work will provide the basis for determining

    Project Gnome was the first nuclear experiment conducted under the U.S. Atomic Energy Commission (AEC), predecessor to the U.S. Department of Energy (DOE), Plowshare Program. Gnome was part of a joint government-industry experiment focused on developing nuclear devices exclusively for peaceful purposes. The intent of the Gnome experiment was to evaluate the effects of a nuclear detonation in a salt medium. Historically, Project Gnome consisted of a single detonation of a nuclear device on December 10, 1961. Since the Gnome detonation, the AEC/DOE has conducted surface restoration, site reconnaissance, and decontamination and decommissioning activities at the site. In addition, annual groundwater sampling is performed under a long-term hydrological monitoring program begun in 1980. Coach, an experiment to be located near the Gnome project, was initially scheduled for 1963. Although construction and rehabilitation were completed for Coach, the experiment was canceled and never executed. Known collectively as Project Gnome-Coach, the site is situated within the Salado Formation approximately 25 miles east of Carlsbad, New Mexico, in Eddy County, and is comprised of nearly 680 acres, of which 60 acres are disturbed from the combined AEC/DOE operations. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the project. The subsurface at the Gnome-Coach site has two contaminant sources that are fundamentally different in terms of both their stratigraphic location and release mechanism. The goal of this characterization is to collect data of sufficient quantity and quality to establish current site conditions and to use the data to identify and evaluate if further action is required to protect human health and the environment and achieve permanent closure of the site. The results of these activities will be presented in a subsequent corrective

  9. Site observational work plan for the UMTRA Project site at Riverton, Wyoming

    International Nuclear Information System (INIS)

    The site observational work plan (SOWP) for the Riverton, Wyoming, Uranium Mill Tailings Remedial Action (UMTRA) Project Site is the first document for the UMTRA Ground Water Project to address site-specific activities to meet compliance with the U.S. Environmental Protection Agency (EPA) proposed ground water standards (52 FR 36000 (1987)). In support of the activities the regulatory framework and drivers are presented along with a discussion of the relationship of this SOWP to other UMTRA Ground Water Project programmatic documents. A combination of the two compliance strategies that will be recommended for this site are no remediation with the application of alternate concentration levels (ACL) and natural flushing in conjunction with institutional controls. ACLs are to be applied to constituents that occur at concentrations above background levels but which are essential nutrients and occur within nutritional ranges and/or have very low toxicity and high dietary intake rates compared to the levels detected in the ground water. The essential premise of natural flushing is that ground water movement and natural attenuation processes will reduce the detected contamination to background levels within 1 00 years. These two recommended compliance strategies were evaluated by applying Riverton site-specific data to the compliance framework developed in the UMTRA Ground Water programmatic environmental impact statement. There are three aquifers beneath the site: a surficial unconfined aquifer, a middle semiconfined aquifer, and a deeper confined aquifer. The milling-related contamination at the site has affected both the surficial and semiconfined aquifers, although the leaky shale aquifers separating these units limits the downward migration of contamination into the semiconfined aquifer. A shale aquitard separates the semiconfined aquifer from the underlying confined aquifer which has not been contaminated by milling-related constituents

  10. Site Observational Work Plan for the UMTRA project site at Ambrosia Lake, New Mexico

    International Nuclear Information System (INIS)

    Ground water compliance for the Uranium Mill Tailings Remedial Action (UMTRA) Project sites, including the Ambrosia Lake, New Mexico, site, is governed by the Uranium Mills Tailings Radiation Control Act (42 USC section 7901 et seq.) and the U.S. Environmental Protection Agency's Health and Environmental Protection Standards for Uranium and Thorium Mill Tailings (40 CFR Part 192; 60 FR 2854). The EPA standards describe specific conditions for which the U.S. Department of Energy (DOE) may apply for supplemental standards for contaminated ground water rather than meeting background levels or numerical standards. To achieve compliance with Subpart A of the EPA standards the residual radioactive materials are currently being consolidated on the site by the DOE in a disposal cell, isolating them from direct human or ecological contact and further dispersion into the environment. Completion of the disposal cell is scheduled for early 1995. An environmental assessment and a Finding of No Significant Impact (FONSI) were completed in 1987. Concurrence with the UMTRA Surface Project Ambrosia Lake remedial action plan (RAP) was granted by the U.S. Nuclear Regulatory Commission (NRC) and state of New Mexico in 1990. The DOE deferred compliance with Subpart B of the EPA standards in the Surface Project RAP. This site observational work plan (SOWP) is the first document to address ground water compliance under Subpart B at the Ambrosia Lake site. The Ambrosia Lake UMTRA Project site is within the Grants Mineral Belt and was one of numerous uranium mills supplied by many local mines. Ground water contamination at the site occurred as a result of uranium mill operations. Contamination of ground water resulted from discharge of waste water, infiltration of water through the tailings pile, hydraulic placement of mill tailings in nearby mines, and water pumped from mine shafts

    The site observational work plan (SOWP) for the Shiprock, New Mexico, Uranium Mill Tailings Remedial Action (UMTRA) Project Site is the initial document for developing site-specific activities to achieve regulatory compliance in the UMTRA Ground Water Project. The regulatory framework used to select the proposed ground water compliance strategies is presented along with a discussion of the relationship of this SOWP to other UMTRA Ground Water Project programmatic documents. The Shiprock site consists of two, interconnected hydrogeologic systems: the terrace system and the floodplain system. Separate compliance strategies are proposed for these two systems. The compliance strategy for the terrace aquifer is no remediation with the application of supplemental standards based on classification of the terrace aquifer as having Class III (limited-use) ground water. The compliance strategy for the floodplain aquifer is active remediation using a subsurface biological barrier. These strategies were selected by applying site-specific data to the compliance framework developed in the UMTRA Ground Water programmatic environmental impact statement (PEIS) (DOE, 1994a). The site conceptual model indicates that milling-related contamination has impacted the ground water in the terrace and floodplain aquifers. Ground water occurs in both aquifers in alluvium and in fractures in the underlying Cretaceous age Mancos Shale. A mound of ground water related to fluids from the milling operations is thought to exist in the terrace aquifer below the area where settling ponds were in use during the mill operations. Most of the water occurring in the floodplain aquifer is from recharge from the San Juan River

    1994-09-01

    Surface cleanup activities at the Mexican Hat UMTRA processing site are nearing completion. Ground Water contamination at the Mexican Hat site is a result of uranium milling operations. The extent of residual process water has been identified, and it is limited to the uppermost aquifer in the vicinity of the site. Deeper aquifers are not affected because of an upward hydraulic gradient and the presence of a confining unit (the deeper aquifers are protected by hydrogeologic isolation). The uppermost unit is returning to its pre-milling, mainly unsaturated state. The unit that contains the contaminated water is not a ground water resource because it qualifies as Class III (limited use) based on limited yield. Ground water in the uppermost unit is currently not used and is not anticipated to be used as a ground water resource. The nearby San Juan River and a converted oil exploration well provide all of the water needs for the area. There are no current threats to human health or livestock; and, because the zone of contamination does not represent a ground water resource, none are anticipated in the future. There are, however, seeps where contaminated water is exposed at land surface. The seeps create potential exposure pathways for plants and wildlife. It is not known at this time if there is a risk to the environment. Additional investigations are needed and are described in this document to confirm the presence or absence of potential environmental risks. Additional hydrogeologic investigations are not required. The proposed ground water compliance strategy for the site is no remediation, because the ground water in the uppermost aquifer (which is also the zone of contamination) qualifies for supplemental standards based on Class III, limited yield, and because there are no threats to human health. Domestic and agricultural water is pumped from a deeper aquifer that is isolated from the contaminated zone.

  2. Case study -- working group C -- Field based site assessment

    International Nuclear Information System (INIS)

    A scheduled tank and line replacement, associated with a service station upgrade in the suburban Boston area, resulted in the discovery of gasoline contaminated soil and ground water. Contamination was encountered during tank excavation and removal activities. Inventory reconciliation and line and tank tightness tests conducted prior to the tank replacement did not indicate any problems with the product storage or transfer systems. During the course of construction the tank pit was over-excavated and contaminated soils were stockpiled (covered) at the rear of the site while awaiting regulatory approval for disposal. Headspace PID readings of soil samples in the proximity of the tank pit ranged up to 110 ppm TPH. Excavated soils remained on site for nearly 3 weeks. Rain was unusually heavy during this period and some run-off occurred onto the abutting property as evidenced by stressed shrubbery along the property line. Native soils consisted of a mixture of sand, organic silts and peat, underlying fill material that consisted of fine to coarse sand, gravel and some silt. Water was encountered at a depth of approximately 4 feet below grade. Continuous dewatering, treatment and discharge to a storm catch basin occurred over a two day period. New fiber-glass tanks and lines were installed in the same excavation as the former steel tanks and lines. Subsequently the station re-opened and resumed normal operations

    A comprehensive, diagnostic, procedural and adaptive scheme involving a combination of geophysical and direct push methods was developed and applied in the Wurmlingen study site situated within the region of Baden-Württemberg (southwest Germany). The goal of the study was to test the applicability of electrical resistivity method in imaging resistivity contrasts, and mapping the depth to and lateral extent of field-scale subsurface structures and existence of flow paths that may control concentration gradients of groundwater solution contents. Based on a relatively fast and cost-effective areal mapping with vertical electrical sounding technique, a northwest-southeast trending stream-channel-like depression (low apparent resistivity feature) through a Pleistocene aquifer was detected. For a more detailed characterization, we implemented electrical resistivity tomography method followed by direct push (DP) technologies. Beside the use of DP for verification of structures identified by geophysical tools, we used it for multi-level groundwater sampling. Results from groundwater chemistry indicate zones of steep nitrate concentration gradients associated with the feature.

  4. Oil field rejuvenation work starts at 14 project sites

    International Nuclear Information System (INIS)

    This paper reports that the U.S. Department of Energy and oil and gas companies have released more information about a joint effort to rejuvenate aging U.S. oil fields in danger of abandonment. Work is starting on 14 demonstration projects that could recover 21 million bbl of oil from the fluvial dominated deltaic (FDD) reservoirs in which they are conducted. Wider application of the same techniques, if they are successful, could results in addition of 6.3 billion bbl of reserves, nearly 25% of U.S. crude oil reserves. A multidisciplinary team approach is to be used, with as many as 11 operators, service companies, universities, or state agencies participating in each project. All of the projects will culminate in extensive technology transfer activities. Here are descriptions of the projects gleaned from public abstracts provided by the DOE contractors

  5. Site observational work plan for the UMTRA Project site at Ambrosia Lake, New Mexico

    International Nuclear Information System (INIS)

    The Ambrosia Lake Uranium Mill Tailings Remedial Action (UMTRA) Project site is within the Grants Mineral Belt and was one of numerous uranium mills supplied by many local mines. Ground water contamination at the site occurred as a result of uranium mill operations. The potential for impacts to human health and the environment from contaminated ground water currently does not exist. No domestic or livestock wells accessing ground water from the uppermost aquifer have been identified within a 5 mile radius from the site. Therefore, no current exposure pathways to humans, livestock, or wildlife exist, nor are any foreseen. The proposed ground water compliance strategy under consideration for application at the Ambrosia Lake site is to perform no remediation, based on the application of supplemental standards because the ground water has ''limited use.''

  6. CO2 storage feasibility: A work-flow for site characterisation

    International Nuclear Information System (INIS)

    In this paper, we present an overview of the SiteChar work-flow model for site characterisation and assessment for CO2 storage. Site characterisation and assessment is required when permits are requested from the legal authorities in the process of starting a CO2 storage process at a given site. The goal is to assess whether a proposed CO2 storage site can indeed be used for permanent storage while meeting the safety requirements demanded by the European Commission (EC) Storage Directive (EU, 2009, Storage Directive 2009/31/EC). Many issues have to be scrutinised, and the work-flow presented here is put forward to help efficiently organise this complex task. Three issues are highlighted: communication within the working team and with the authorities; interdependencies in the work-flow and feedback loops; and the risk-based character of the work-flow. A general overview (helicopter view) of the work-flow is given; the issues involved in communication and the risk assessment process are described in more detail. The work-flow as described has been tested within the SiteChar project on five potential storage sites throughout Europe. This resulted in a list of key aspects of site characterisation which can help prepare and focus new site characterisation studies. (authors)

  7. Site observational work plan for the UMTRA Project Site at Riverton, Wyoming. Revision 3/95

    International Nuclear Information System (INIS)

    Ground water compliance for the Uranium Mill Tailings Remedial Action (UMTRA) Project sites, including the Riverton, Wyoming, site, is governed by the Uranium Mill Tailings Radiation Control Act and the US Environmental Protection Agency's Health and Environmental Protection Standards for Uranium and Thorium Mill Tailings. The compliance strategy proposed for this site is natural flushing in conjunction with institutional controls. The essential premise of natural flushing is that ground water movement and natural attenuation processes will reduce the detected contamination to background levels or alternate concentration limits that do not pose a risk to human health or the environment within 100 years. This document contains the following sections. Section 2.0 of this SOWP describes the requirements for meeting standards at UMTRA Project sites. Section 3.0 provides site-specific data and the related conceptual model. Section 4.0 provides the justification for the recommended ground water compliance strategy for the Riverton site. Section 5.0 provides the justification and process for collection and assessment of additional required data. Section 6.0 provides a list of the references cited. The appendixes include data on monitor wells and lithography, ground water, surface water, and sediment quality

  9. Site observational work plan for the UMTRA Project site at Tuba City, Arizona

    International Nuclear Information System (INIS)

    The requirements for ground water compliance for Uranium Mill Tailings Remedial Action (UMTRA) Project sites, including the Tuba City, Arizona, site, are found in the Uranium Mill Tailings Radiation Control Act; Subparts B and C of the U.S. Environmental Protection Agency's Health and Environmental Protection Standards for Uranium and Thorium Mill Tailings (40 CFR 192 (1994)), and the associated proposed 1987 standards (52 FR 36000). During the surface remedial action, an estimated 1,400,000 cubic yards (yd3) (1,100,000 cubic meters [m3]) of uranium mill tailings and other contaminated materials were consolidated and stabilized in place in an unlined disposal cell covering 50 acres (20 hectares). The surface remedial action was completed in April 1990. Ground water beneath the Tuba City site was contaminated by subsurface migration of water from uranium ore processing activities. The main source of contaminants was water from the tailings piles that began in 1956 when the mill opened and ended in 1966 when the mill closed. 800,000 tons (725,000 tonnes) of uranium ore were processed onsite over a 10-year period. The wet tailings remaining after processing were placed as a slurry in three piles at the site. Water from these tailings then seeped into the ground and migrated downward to the ground water. The Tuba City site is currently in a post-stabilization, prelicensing status. The site is expected to remain in this status until licensed by the U.S. Nuclear Regulatory Commission (NRC) for long-term surveillance and maintenance. The preliminary ground water compliance strategy at the Tuba City site is active remediation-specific technology to be evaluated is in situ bioremediation. This selection was made because of the potential ability of bioremediation to reduce concentrations to lower levels than a conventional extraction system and to minimize disturbance of the water resource

  12. Site observational work plan for the UMTRA Project site at Spook, Wyoming

    International Nuclear Information System (INIS)

    Ground water in the uppermost aquifer beneath and downgradient from the Spook site was contaminated by uranium-processing activities that occurred from 1962 until 1966. Contamination from the tailings pile and the acid pond (including uranium, selenium, nitrate, and radium-226 and -228) leached into the subsurface by infiltration and migrated into ground water, forming a plume extending approximately 2,500 feet (ft) (760 meters [m]) downgradient from the site. The surface remedial action at the Spook site under Subpart A of 40 CFR Part 192 consisted of stabilizing the uranium mill tailings and other residual radioactive materials in a disposal cell in the bottom of the Spook open-pit mine and covering the cell with overburden material. The ground water protection strategy was supplemental standards based on Class 3 ground water in the uppermost aquifer because of widespread ambient contamination. The proposed ground water protection strategy to comply with Subpart B of 40 CFR Part 192 at the Spook site is to perform no remediation. This strategy is based on ground water in the uppermost aquifer (also the zone of contamination) being classified as Class 3, which allows the application of supplemental standards. Class 3 ground water beneath the Spook site is neither a current nor a potential source of drinking water because of widespread, ambient contamination that cannot be cleaned up using treatment methods reasonably employed in public water supply systems

  14. Site observational work plan for the UMTRA project site at Falls City, Texas

    International Nuclear Information System (INIS)

    During surface remedial action, an estimated 7.0 million tons (6.4 million tonnes) of uranium mill tailings and other contaminated materials were consolidated and stabilized on the Falls City site. The ground water protection strategy at the Falls City disposal site for the UMTRA Surface Project (Subpart A of 40 CFR Part 192 (1994)) was an application for supplemental standards, based on Class III (limited use) ground water in the uppermost aquifer. This water is not a current or potential source of drinking water. Ground water from the uppermost aquifer (ground water from the Deweesville/Conquista Members and the Dilworth Member) contains widespread ambient contamination resulting from naturally occurring conditions and from the effects of human activity not related to uranium milling operations (uranium exploration and mining activities). The ground water cannot be effectively cleaned up for drinking or other beneficial purposes using treatment methods reasonably employed by public water supply systems. The U.S. Nuclear Regulatory Commission (NRC) and the state of Texas concurred with the ground water protection strategy for the disposal site in September 1992. Surface remedial action in accord with Subpart A was completed in April 1994. The proposed ground water compliance strategy (Subpart B of 40 CFR Part 192 (1994)) at the Falls City site is to perform no remedial action based on application for supplemental standards because the ground water in the uppermost aquifer is classified as Class III ground water. Class III ground water includes ground water that is not a current or potential source of drinking water because of widespread, ambient contamination that cannot be cleaned up using treatment methods reasonably employed by public water supply systems (40 CFR section 192.11 (e) (1994)). Although supplemental standards are being applied, the potential use of ground water in the site vicinity will be protected

    This study is one of the first to explore the relevance of trust to the health of adolescents living in a disadvantaged urban setting. The primary objectives were to determine the differences in the sociodemographic characteristics between adolescents who do and do not trust and to examine the associations between trust and health. Data were drawn from the Well-Being of Adolescents in Vulnerable Environments (WAVE) study, which is a cross-sectional global study of adolescents in very low-income urban settings conducted in 2011-2013. This paper focused on 446 adolescents in Baltimore as it was the primary site where trust was explicitly measured. For the main analyses, six health outcomes were examined: (1) self-rated health; (2) violence victimization; (3) binge drinking; (4) marijuana use; (5) post-traumatic stress disorder (PTSD); and (6) condom use at last sex. Independent variables included sociodemographic variables (age, gender, current school enrolment, perceived relative wealth, and family structure) and two dimensions of trust: community trust (trust in individuals/groups within neighborhood) and institutional trust (trust in authorities). The results show that more than half the sample had no trust in police, and a high proportion had no trust in other types of authority. Among girls, those with higher levels of community trust were less likely to be victimized and involved in binge drinking. Meanwhile, girls with higher levels of institutional trust were more likely to use a condom and less likely to have used marijuana. Among boys, those with higher levels of community trust were more likely to use a condom, while those with higher levels of institutional trust were less likely to use marijuana, but more likely binge drink. Overall, this study highlights the importance of trust for adolescent health. Most surprising were the differences in the associations between boys and girls with regard to the type of trust and specific health outcome that was

  19. Geodesy work at Dukovany nuclear power plant site as viewed by higher building work contractor

    International Nuclear Information System (INIS)

    Geodesy work during the Dukovany nuclear power plant construction proceeded with considerable difficulties. Micronetwork points connected to an external network of fixed points were fitted onto the foundation slab of teh reactor rooms. The micronetwork was stabilized on reinforced concrete pillars joined to the reinforcement in the foundation slab. The network alignment showed an accuracy of ±0.4 to 0.8 mm. The network served as a skeleton from which the individual parts of the reactor room were laid out. In view of the uneven progress of building vertical structures, the network could not be lifted to higher floors as a whole but the individual points were joined into polygons. The so-called geodetic bridge which considerably accelerated work, and the polar measuring methods were used near the shaft. The measurement showed that all tolerances required by the design could not continuously be observed and that some were rather controversial. Only the initiative of labour and the perfect production preparation by the assembly organisation made possible the manufacture of building structures within the required tolerances. (J.B.)

  6. Site Characterization Work Plan for the Gnome-Coach Site, New Mexico (Rev. 1, January 2002); FINAL

    International Nuclear Information System (INIS)

    Project Gnome was the first nuclear experiment conducted under the U.S. Atomic Energy Commission (AEC), predecessor to the U.S. Department of Energy (DOE), Plowshare Program. The Plowshare Program focused on developing nuclear devices exclusively for peaceful purposes. The intent of the Gnome experiment was to evaluate the effects of a nuclear detonation in a salt medium. Historically, Project Gnome consisted of a single detonation of a nuclear device on December 10, 1961 with the Salado Formation. Since the Gnome detonation, the AEC/DOE has conducted surface restoration, site reconnaissance, and decontamination and decommissioning activities at the site. In addition, annual groundwater sampling is performed under a long-term hydrological monitoring program begun in 1972. Coach, an experiment to be located near the Gnome project, was initially scheduled for 1963. Although construction and rehabilitation were completed for Coach, the experiment was canceled and never executed. Known collectively as Project Gnome-Coach, the site is located approximately 25 miles east of Carlsbad, New Mexico, in Eddy County, and is comprised of nearly 680 acres, of which approximately 60 acres are disturbed from the combined AEC/DOE operations. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the project. The subsurface at the Gnome-Coach site has two contaminant sources that are fundamentally different in terms of both their stratigraphic location and release mechanism. The goal of this characterization is to collect data of sufficient quantity and quality to establish current site conditions and to use the data to identify and evaluate if further action is required to protect human health and the environment and achieve permanent closure of the site. The results of these activities will be presented in a subsequent corrective action decision document

  11. A new thermodynamic model for shaft work targeting on total sites

    International Nuclear Information System (INIS)

    The purpose of the paper is to introduce a targeting model based on a new thermodynamic insight on cogeneration in general and Rankine cycle in particular. The insight permits to express the ideal shaft work of a cogeneration unit through the outlet heat load and the difference in Carnot factors between the heat source and heat sink for the given inlet temperature of the heat source. The deviation from the ideal shaft work to the real one is assessed by using the traditionally turbine isentropic efficiency. Finally the new model allows targeting fuel consumption, cooling requirement and shaft work production with high accuracy and visualizing them directly as special segments on the T-H diagram. A modified Site Utility Grand Composite Curve (Succ) diagram is proposed and compared to the original Succ. The shape of the right hand side of the diagram above site pinch is the same, however, below site pinch it is shifted to the left by an amount equal to shaftwork production below site pinch. Above site pinch Vp consumption is also corrected to account for shaftwork production above site pinch that is represented by segments rather than areas on the left hand side of the T-H diagram

    2013-02-01

    Chicago's CeaseFire program is an evidence-based public health approach to preventing gun violence. Baltimore is one of many US cities attempting to replicate the program. We compared changes in the number of homicide and nonfatal shooting incidents per month in four intervention neighborhoods with changes in high-crime comparison areas (police posts) without the intervention, while controlling for several measures of police activity and baseline levels of homicide and nonfatal shootings. In South Baltimore there were large program-related reductions in homicide and nonfatal shooting incidents. Among three East Baltimore program sites, the program was associated with a reduction of homicides in one area, a reduction in nonfatal shootings in another area, and a simultaneous increase in homicides and decrease in nonfatal shootings in another area. In some instances, program effects extended to neighborhoods bordering the intervention areas.

    International Nuclear Information System (INIS)

    The purpose of this document is to provide additional and more detailed information to supplement review of the site observational work plan (SOWP) for the Ambrosia Lake, New Mexico, Uranium Mill Tailings Remedial Action (UMTRA) Project site. This document includes a discussion of (1) the average linear velocity of the ground water in the alluvium; (2) the ground water quality of the alluvium, weathered Mancos Shale, and the Tres Hermanos-C Member of the Mancos Shale; and (3) the fate and transport of contaminants from the uppermost aquifer to the Westwater Canyon Member of the Morrison Formation. The data from a 1989 aquifer test were analyzed using the curve-matching software AQTESOLV and then compared with the original results. A hydrograph of the ground water elevations in monitoring wells screened in the alluvium is presented to show how the ground water elevations change with time. Stiff and Piper diagrams were created to describe the changes in ground water geochemistry in the alluvium/weathered Mancos Shale unit, the Tres Hermanos-C Sandstone unit, the Tres Hermanos-B Sandstone unit, and the Dakota Sandstone. Background information on other related topics such as site history, cell construction, soil characteristics, and well construction are presented in the SOWP. Figure 1 is a geologic cross section depicting the conceptual model of the hydrostratigraphy and ground water chemistry of the Ambrosia Lake site.

    The City of Baltimore, like any city, is the sum of its component neighborhoods, institutions, businesses, cultures, and, ultimately, its people. It is also an organism in its own right, with distinct geography, history, infrastructure, and environments that shape its residents even as it is shaped by them. Sometimes these interactions are obvious but often they are not; while basic economic patterns are widely documented, the distribution of socio-spatial and environmental connections often hides below the surface, as does the potential that those connections hold. Here we present results of a collaborative initiative on the geography, design, and policy of socio-environmental dynamics of Baltimore. Geospatial data derived from satellite imagery, demographic databases, social media feeds, infrastructure plans, and in situ environmental networks, among other sources, are applied to generate an interactive portrait of Baltimore City's social, health, and well-being dynamics. The layering of data serves as a platform for visualizing the interconnectedness of the City and as a database for modeling risk interactions, vulnerabilities, and strengths within and between communities. This presentation will provide an overview of project findings and highlight linkages to education and policy.

  18. Human Health and Ecological Risk Assessment Work Plan Mud Pit Release Sites, Amchitka Island, Alaska

    DOE/NV

    2001-03-12

    This Work Plan describes the approach that will be used to conduct human health and ecological risk assessments for Amchitka Island, Alaska, which was utilized as an underground nuclear test site between 1965 and 1971. During this period, the U.S. Atomic Energy Commission (now the U.S. Department of Energy) conducted two nuclear tests (known as Long Shot and Milrow) and assisted the U.S. Department of Defense with a third test (known as Cannikin). Amchitka Island is approximately 42 miles long and located 1,340 miles west-southwest of Anchorage, Alaska, in the western end of the Aleutian Island archipelago in a group of islands known as the Rat Islands. Historically including deep drilling operations required large volumes of drilling mud, a considerable amount of which was left on the island in exposed mud pits after testing was completed. Therefore, there is a need for drilling mud pit remediation and risk assessment of historical mud pit releases. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the constituents in soil, surface water, and sediment at these former testing sites. Its goal is the collection of data in sufficient quantity and quality to determine current site conditions, support a risk assessment for the site surfaces, and evaluate what further remedial action is required to achieve permanent closure of these three sites that will protect both human health and the environment. Suspected compounds of potential ecological concern for investigative analysis at these sites include diesel-range organics, polyaromatic hydrocarbons, polychlorinated biphenyls, volatile organic compounds, and chromium. The results of these characterizations and risk assessments will be used to evaluate corrective action alternatives to include no further action, the implementation of institutional controls, capping on site, or off-sit e

  20. Sectored Clean-up Work Plan for Housekeeping Category Waste Sites

    International Nuclear Information System (INIS)

    The Sectored Clean-up Work Plan (SCWP) replaces the Housekeeping Category Corrective Action Unit Work Plan and provides a strategy to be used for conducting housekeeping activities using a sectored clean-up approach. This work plan provides a process by which one or more existing housekeeping category Corrective Action Sites (CASS) from the Federal Facility Agreement and Consent Order and/or non-FFACO designated waste site(s) are grouped into a sector for simultaneous remediation and cleanup. This increases effectiveness and efficiencies in labor, materials, equipment, cost, and time. This plan is an effort by the U.S. Department of Energy to expedite work in a more organized and efficient approach. The objectives of this plan are to: Group housekeeping FFACO CASS and non-FFACO housekeeping sites into sectors and remediate during the same field visit; Provide consistent documentation on FFACO CAS and non-FFACO clean-up activities; Perform similar activities under one approved document; Remediate areas inside the Deactivation and Decommissioning facilities and compounds in a campaign-style remediation; and Increase efficiencies and cost-effectiveness, accelerate cleanups, reduce mobilization, demobilization, and remediation costs

    Project Gasbuggy was the first of three joint government-industry experiments conducted to test the effectiveness of nuclear explosives to fracture deeply buried, low-permeability natural gas reservoirs to stimulate production. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the Project Gasbuggy Site. Its goal is the collection of data in sufficient quantity and quality to determine current site conditions, support a risk assessment for the site surfaces, and evaluate if further remedial action is required to achieve permanent closure of the site that is both protective of human health and the environment. The Gasbuggy Site is located approximately 55 air miles east of Farmington, New Mexico, in Rio Arriba County within the Carson National Forest in the northeast portion of the San Juan Basin. Historically, Project Gasbuggy consisted of the joint government-industry detonation of a nuclear device on December 10, 1967, followed by reentry drilling and gas production testing and project evaluation activities in post-detonation operations from 1967 to 1976. Based on historical documentation, no chemical release sites other than the mud pits were identified; additionally, there was no material buried at the Gasbuggy Site other than drilling fluids and construction debris. Although previous characterization and restoration activities including sensitive species surveys, cultural resources surveys, surface geophysical surveys, and limited soil sampling and analysis were performed in 1978 and again in 2000, no formal closure of the site was achieved. Also, these efforts did not adequately address the site's potential for chemical contamination at the surface/shallow subsurface ground levels or the subsurface hazards for potential migration outside of the current site subsurface intrusion restrictions.

    2013-01-01

    This study used OWAS to analyze the working postures of construction workers on building the foundations of a log cabin. Three construction workers, with an average work experience of 40 years, participated in this study. Eight elementary jobs of building the foundations of a log cabin were videotaped at a construction site and analyzed later in the laboratory. For an overall distribution of trunk postures, OWAS identified that a bent and twisted trunk posture (34%), which fell into action category 3, was the major poor posture for construction workers. This study also identified that tying beams with steel bars, assembling column templates, and cement grouting of the ground were the 3 principal jobs in which workers building the foundations exhibited poor working posture. This article suggests ways to reduce and evaluate poor posture in a dynamic construction site. PMID:23759194

    2016-06-01

    Aerosol hygroscopicity was investigated using a novel dryer-humidifier system, coupled to a TSI-3563 nephelometer, to obtain the light scattering coefficient (σscat) as a function of relative humidity (RH) in hydration and dehydration modes. The measurements were performed in Porterville, CA (10 January to 6 February 2013), Baltimore, MD (3-30 July 2013), and Golden, CO (12 July to 10 August 2014). Observations in Porterville and Golden were part of the NASA-sponsored Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality project. The measured σscat under varying RH in the three sites was combined with ground aerosol extinction, PM2.5 mass concentrations, and particle composition measurements and compared with airborne observations performed during campaigns. The enhancement factor, f(RH), defined as the ratio of σscat(RH) at a certain RH divided by σscat at a dry value, was used to evaluate the aerosol hygroscopicity. Particles in Porterville showed low average f(RH = 80%) (1.42) which was attributed to the high carbonaceous loading in the region where residential biomass burning and traffic emissions contribute heavily to air pollution. In Baltimore, the high average f(RH = 80%) (2.06) was attributed to the large contribution of SO42- in the region. The lowest water uptake was observed in Golden, with an average f(RH = 80%) = 1.24 where organic carbon dominated the particle loading. Different empirical fits were evaluated using the f(RH) data. The widely used Kasten (gamma) model was found least satisfactory, as it overestimates f(RH) for RH fit with two power law curve fitting parameters c and k was found to replicate f(RH) accurately from the three sites. The relationship between the organic carbon mass and the species that are affected by RH and f(RH) was also studied and categorized.

  5. Caxingo - a promising model for integrating the hydroelectric work camps to the site communities

    International Nuclear Information System (INIS)

    The social and economical impacts caused by the hydroelectric work camps in the sites where the hydroelectric will be constructed are studied, analysing the great supply of works when the hydroelectric is been constructed face to the reduction one when the works are concluded; the neglect by the State in providing medical and educational assistances to the neighbour populations; the appearance of a commerce in the neighbour areas; the employer stableness in the camp after the pension and the lack by the neighbour cities of a social and economical substructure to offer to the population, that come with the hydroelectric construction. A new solution for these problems is presented in the Xingo camp, where the camp will be as a district of city near to the work, with community services provide by the State and the needful substructure to its construction and the equipment provide by the concessionaire.

    The objective of this study was to establish baseline data about air pollutants potentially related to nasopharyngeal carcinoma (NPC) in the Federal Territory and Selangor, Malaysia. During 1991-1993, ambient air quality was monitored at 42 work sites representing ten industrial sectors: adhesive manufacturing, foundries, latex processing, metalworking, plywood/veneer milling, ricemilling, rubber tire manufacturing, sawmilling, shoemaking, and textile related industries. At each work site, aerosol particle size distributions and concentrations of formaldehyde, benzene, toluene, isopropyl alcohol, and furfural were measured. Mean aerosol particle concentrations ranged from 61 micrograms/m3 in foundries to 5,578 micrograms/m3 in ricemills, with five industries (adhesives, metalworking, ricemilling, sawmilling, and shoemaking) exceeding the US EPA 24-hr ambient air standard for PM-10. Formaldehyde concentrations exceeded the threshold limit value (TLV) in adhesives factories. Other vapours and elements measured were well below TLVs. PMID:12109256

    2010-02-12

    The Hanford Nuclear Reservation occupies an area of 586 square miles in southeastern Washington state. The site was created as part of the World War II Manhattan Project to produce weapons grade plutonium. A multitude of old reactor plants, processing facilities, underground tank farms, contaminated soil and ground water remain and are part of an on-going environmental cleanup mission of the site. The Columbia River bisects Hanford, and the concern is that the river will become contaminated if the sources of contamination are not removed. Currently facilities are being removed, the ground water is being treated, and contaminated soil is being transferred to an approved burial ground about 15 miles away from the River located in the center of the Hanford Site The remaining facilities and adjacent structures are undergoing D&D (decontaminate and demolish) and to date, significant progress has been made. During this presentation, I will discuss how we are using innovative tools and work practices to D&D these Hanford Site facilities.

  13. Robust remediation strategies at gas-work sites: a case of source recognition and source characterization

    International Nuclear Information System (INIS)

    In The Netherlands there have been gasworks at about 260 to 270 locations. Most of these locations are or were heavily polluted with tar, ashes and cyanides and many of them belong to the locations where remediation actions have already been executed. It seems however that many of them also belong to the locations where remediation actions were not quite as successful as was expected. So, for many gas-work sites that were already 'remedied' in the 80's and early 90's of the foregoing century, new programs for site remediation are planned. Of course the mistakes from the past should now be avoided. The current remediation strategy in The Netherlands for gas-work sites can be comprised in four steps: 1 - removing spots in the top soil, 2 - removing spots with mobile components in the shallow subsoil, 3 - controlling spots with mobile components in the deep subsoil, 4 - creating a 'steady endpoint situation' in the plume. At many former gas-work sites real sources, i.e. in a physico-chemical sense, are not very well known. This can easily lead to insufficient removal of some or part of these sources and cause a longer delivery of contaminants to the groundwater plume, with higher endpoint concentrations, higher costs and more restrictions for future use. The higher concentrations and longer deliveries originating from not recognized or not localized sources are often not sufficiently compensated by the proposed plume management in current remediation strategies. Remediation results can be improved by using knowledge about the processes that determine the delivery of contaminants to the groundwater, the materials that cause these delivery and the locations at the site where these are most likely found. When sources are present in the deep subsoil or the exact localization of sources is uncertain, robust remediation strategies should be chosen and wishful thinking about removing sources with in situ techniques should be avoided. Robust strategies are probably less

    Urban areas are responsible for a major component of the anthropogenic greenhouse gas (GHG) emissions. Quantification of urban GHG fluxes is important for establishing scientifically sound and cost-effective policies for mitigating GHGs. Discrepancies between observations and model simulations of GHGs suggest uncharacterized sources in urban environments. In this work, we analyze and quantify fluxes of CO2, CH4, CO (and other trace species) from the Baltimore-Washington area based on the mass balance approach using the two-aircraft observations conducted in February-March 2015. Estimated fluxes from this area were 110,000±20,000 moles s-1 for CO2, 700±330 moles s-1 for CH4, and 535±188 moles s-1 for CO. This implies that methane is responsible for ~20% of the climate forcing from these cities. Point sources of CO2 from four regional power plants and one point source of CH4 from a landfill were identified and the emissions from these point sources were quantified based on the aircraft observation and compared to the emission inventory data. Methane fluxes from the Washington area were larger than from the Baltimore area, indicating a larger leakage rate in the Washington area. The ethane-to-methane ratios, with a mean of 3.3%, in the limited canister samples collected during the flights indicate that natural gas leaks and the upwind oil and natural gas operations are responsible for a substantial fraction of the CH4 flux. These observations will be compared to models using Ensemble Kalman Filter Assimilation techniques.

  19. Radioecological surveillance around an old mining and milling site during environmental remediation works

    International Nuclear Information System (INIS)

    The main site of historic uranium mining and milling in Portugal, near the town of Canas de Senhorim, contains around 2.5 million tones of solid waste containing radioactivity in various mill tailings and spoil heaps. Approval of an environmental remediation plan for this area was followed by the start of engineering works, including the transportation of milling waste to the main milling pile and re shaping and contouring the waste heap to put a cap layer. These works were mostly performed in 2006 and 2007. During part of this period monitoring of radioactivity, including radon, was performed in the surface air, surface waters from the area, including the monitoring of the small river that receives drainage from the mill tailings area, and agriculture products. This paper presents the results of measurements of the main alpha emitting radionuclides of uranium series and compares them with previous data from the region. Implications for the radiological protection of the population are discussed. (author)

  1. Study protocol: the effects of work-site exercise on the physical fitness and work-ability of older workers

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Abstract Background Older workers have a higher rate and cost of injury than younger workers and with a rapidly ageing work force there is a need to identify strategies to address this problem. Older workers are less physically active and fit than younger workers and so have reduced work ability. The reduced work ability means they are more likely to be fatigued at work and so at greater risk of injury. Exercise could potentially assist this problem. Exercise training has been previously shown to improve fitness in older people however there has been no evaluation of workplace exercise program for older workers. We do not know if the programs are feasible and can improve the fitness and work ability of older workers. We have designed a randomised controlled trial to evaluate whether exercise improves fitness and perceived work-ability of older workers. Methods/Design This paper describes the protocol for a trial examining the effects of a 12-week physical training program in workers over the age of 45. Participants will be randomized to an exercise or no-intervention control group. The primary outcomes are cardiorespiratory endurance, lifting capacity, upper and lower limb strength and perceived work-ability. Discussion This trial will test the feasibility of implementing a worksite-based exercise program as a means of improving the physical fitness and work-ability of older workers performing physically demanding work. If we demonstrate the feasibility of the program we will conduct a larger trial that additionally measures injury outcomes.

  3. Impact of Construction Waste Disposal Charging Scheme on work practices at construction sites in Hong Kong

    International Nuclear Information System (INIS)

    Highlights: ► A significant reduction of construction waste was achieved at the first 3 years of CWDCS implementation. ► However, the reduction cannot be sustained. ► Implementation of the CWDCS has generated positive effects in waste reduction by all main trades. - Abstract: Waste management in the building industry in Hong Kong has become an important environmental issue. Particularly, an increasing amount of construction and demolition (C and D) waste is being disposed at landfill sites. In order to reduce waste generation and encourage reuse and recycling, the Hong Kong Government has implemented the Construction Waste Disposal Charging Scheme (CWDCS) to levy charges on C and D waste disposal to landfills. In order to provide information on the changes in reducing waste generation practice among construction participants in various work trades, a study was conducted after 3 years of implementation of the CWDCS via a structured questionnaire survey in the building industry in Hong Kong. The study result has revealed changes with work flows of the major trades as well as differentiating the levels of waste reduced. Three building projects in the public and private sectors were selected as case studies to demonstrate the changes in work flows and the reduction of waste achieved. The research findings reveal that a significant reduction of construction waste was achieved at the first 3 years (2006–2008) of CWDCS implementation. However, the reduction cannot be sustained. The major trades have been influenced to a certain extent by the implementation of the CWDCS. Slight improvement in waste management practices was observed, but reduction of construction waste in the wet-finishing and dry-finishing trades has undergone little improvement. Implementation of the CWDCS has not yet motivated subcontractors to change their methods of construction so as to reduce C and D waste.

    Levine, A. L.

    1981-01-01

    An engineer and a computer expert from Goddard Space Flight Center were assigned to provide technical assistance in the design and installation of a computer assisted system for dispatching and communicating with fire department personnel and equipment in Baltimore City. Primary contributions were in decision making and management processes. The project is analyzed from four perspectives: (1) fire service; (2) technology transfer; (3) public administration; and (5) innovation. The city benefitted substantially from the approach and competence of the NASA personnel. Given the proper conditions, there are distinct advantages in having a nearby Federal laboratory provide assistance to a city on a continuing basis, as is done in the Baltimore Applications Project.

  7. Hydrophobic organic contaminants in surficial sediments of Baltimore Harbor: Inventories and sources

    International Nuclear Information System (INIS)

    The heavily urbanized and industrialized Baltimore Harbor/Patapsco River/Back River system is one of the most highly contaminated regions of the Chesapeake Bay. In June 1996, surficial sediments were collected at 80 sites throughout the subestuarine system, including historically undersampled creek sand embayments. The samples were analyzed for a suite of hydrophobic organic contaminants (HOCs) consisting of 32 polycyclic aromatic hydrocarbons (PAHs) and 113 polychlorinated biphenyl (PCB) congeners. Total PAH and total PCB concentrations ranged from 90 to 46,200 and 8 to 2,150 ng/g dry weight, respectively. There was enormous spatial variability in the concentrations of HOCs, which was not well correlated to grain size or organic carbon content, suggesting nonequilibrium partitioning and/or proximity to sources as important factors explaining the observed spatial variability. High concentrations of both classes of HOCs were localized around major urban stormwater runoff discharges. Elevated PAH concentrations were also centered around the Sparrow's Point Industrial Complex, most likely a result of the pyrolysis of coal during the production of steel. All but 1 of the 80 sites exceeded the effects range-low (ERL) for total PCBs and, of those sites, 40% exceeded the effects range-medium (ERM), suggesting toxicity to marine benthic organisms would frequently occur. Using principal component analysis, differences in PAH signatures were discerned. Higher molecular weight PAHs were enriched in signatures from sediments close to suspected sources (i.e., urban stormwater runoff and steel production complexes) compared to those patterns observed at sites further from outfalls or runoff. Due to varying solubilities and affinities for organic matter of the individual PAHs, partitioning of the heavier weight PAHs may enrich settling particles with high molecular weight PAHs. Lower molecular weight PAHs, having lower affinity for particles, may travel from the source to a

    Muntaner, C; Parsons, P E

    1996-01-01

    Most studies of inequalities and access to health care have used income as the sole indicator of social stratification. Despite the significance of social theory in health insurance research, there are no empirical studies comparing the ability of different models of social stratification to predict health insurance coverage. The aim of this study is to provide a comparative analysis using a variety of theory-driven indicators of social stratification and assess the relative strength of the association between these indicators and private health insurance. Data were collected in a 1993 telephone interview of a random digit dialing sample of the white population in the Baltimore Metropolitan Statistical Area. Indicators of social stratification included employment status, full-time work, education, occupation, industry, household income, firm size, and three types of assets: ownership, organizational, and skill/credential. The association between social stratification and private health insurance was strongest for those having higher household incomes, having attained at least a bachelor's degree, and working in a firm with more than 50 employees, followed by being an owner or manager, and by being employed. The addition of education and firm size improved the prediction of the household income model. The authors conclude that studies of inequalities in health insurance coverage can benefit from the inclusion of theory-driven indicators of social stratification such as human capital, labor market segmentation, and control over productive assets.

  14. Protecting Baltimore's waters from toxic substances in urban storm drains

    International Nuclear Information System (INIS)

    The City of Baltimore received a National Pollutant Discharge Elimination System (NPDES) municipal storm water permit in January 1994. A major effort under the permit was to develop a program to identify and eliminate illicit entries into the municipal storm water system. Approximately one third of the storm drain outfalls have been targeted under this program. The outfalls correspond to sections of the storm drain system inspected for the development of a storm drain infra-structure data base. During the infra-structure inspections, samples were collected and flow measurements were taken at storm water outfalls. Any suspended illicit discharges were sent to the laboratory where they were analyzed for a suite of toxicants and other pollutants include: surfactants, phenols, ammonia, copper, lead, zinc, residual chlorine and total petroleum hydrocarbons. The laboratory data provided the basis for ranking the subwatersheds from least to most polluted. These rankings were then used to design a dry weather sampling program so that the most polluted watersheds are sampled more frequently (e.g., monthly) than the least polluted (annually). Repeated high pollution levels initiate an investigation at sequential sampling points upstream until the pipe segment receiving the discharge is identified. A geographical information system is used to assist in identifying potential sources of contamination (e.g., industries) in the suspected drain segment

  15. That very interesting dance in the Baltimore Canyon

    1978-09-11

    Pointing out that offshore oil and gas has been a marginal proposition until now--the only consistent moneymaker being the Federal government as leaser--it is hard to understand the feverish spasms that have swept the stock market for months, at the slightest hint of a discovery in Baltimore Canyon. Despite the dismal returns vs. risks up to the present, most of the oil industry believes it must continue offshore if it wants to stay in the oil and gas business. Most of these oil men widely share the belief that most of the large fields that remain to be discovered are in frontier areas of the continential shelf; and one ''big elephant'' discovered can easily erase a string of losses. Still another reason to keep playing is an astonishing advance in exploration technology known as ''bright spots''. Finally, oil men are lured into the offshore arena by a subtle mixture of perceived necessity, an innate if somewhat battered spirit of optimism, and an unabashed fascination with the game itself--the latter, little understood outside the industry according to Dick Palmer, Texaco's top exploration man, but ''a very interesting dance''.

  16. Final work plan: Expedited Site Characterization of the IES Industries, Inc., Site at Marshalltown, Iowa. Ames Expedited Site Characterization Project, Version 1.0

    Energy Technology Data Exchange (ETDEWEB)

    1994-04-04

    The overall goal of the Ames Laboratory Expedited Site Characterization (ESC) project is to evaluate and promote both innovative and state-of-the-practice site characterization and/or monitoring technologies. This will be accomplished by fielding both types of technologies together in the context of an expedited site characterization. The first site will be at a former manufactured gas plant (FMGP) in Marshalltown, Iowa. The project will field three areas of technology: geophysical, analytical, and data fusion. Geophysical technologies are designed to understand the subsurface geology to help predict fate and transport of the target contaminants. Analytical technologies/methods are designed to detect and quantify the target contaminants. Data fusion technology consists of software systems designed to rapidly integrate or fuse all site information into a conceptual site model that then becomes the decision making tool for the site team to plan subsequent sampling activity. Not all of the contaminants present can be located at the action level. Polynuclear aromatic hydrocarbons (PAHs) are the signature organics associated with the coal tar activities that took place at the site. As a result, PAHs were selected as the target compounds. Screening analytical instruments and nonintrusive geophysical techniques will be fielded to qualitatively map the spatial contaminant distribution. Soil gas surveys, immunoassay testing (IMA), innovative optical techniques, and passive organic sorbent sensors will be deployed along with the geophysical methods. Gas chromatography/mass spectrometry (GC/MS) instruments and a cone penetrometer system equipped with a laser-induced fluorescence (LIF) probe will quantitatively map the action level edges of the PAH plume(s). Samples will be taken both by the cone penetrometer test system (CPT) and the Geoprobe {reg_sign} sampler system.

    ; the generally favorable review of the unique safety aspects of the US MHTGR design by the US. Nuclear Regulatory Commission (NRC) in their draft Safety Evaluation Report; the increasing interest by gradually more and more industrializing countries and even a few new industrialized countries in incorporating MRTGRs into their plans for expanded electricity production and for enhanced oil recovery and district heating. Most of the papers provided an expansion of views or details of the development work supporting the national programs or perspectives outlined during the preceding International Conference. Apparent throughout was the gradually increasing effort taking place in the world to support the modular HTGR and the recognition that the demonstration of its unique characteristics is the logical next step in commercialization of the concept. The view expressed by industrializing countries in terms of application studies, siting and licensing aspects and by industrialized countries in terms of design and development progress, project prospects, cost analyses and long range technological growth potential into higher temperature industrial applications provided substantial evidence to this increasing recognition

    Computer operators at two work sites (n = 73, n = 19) were prompted to take three 30-s and one 3-min break from computer work each hour in addition to conventional rest breaks. Some operators were asked to perform stretching exercises during the short breaks. Mood state and musculoskeletal discomfort were assessed at each work site over a 2- or 3-week baseline period and a 4- or 6-week treatment period, respectively. Operator productivity measures were obtained from company records. Operators complied with about half of the added breaks but favoured 3-min breaks over 30-s breaks. No improvement in productivity or well-being was found at the larger work site. At the smaller work site, productivity, eye, leg and foot comfort all improved when the short breaks included stretching exercises. These results provide evidence that frequent short breaks from continuous computer-mediated work can benefit worker productivity and well-being when the breaks integrate with task demands.

    International Nuclear Information System (INIS)

    This work plan and attached supporting project plans establish the operable unit setting and the objectives, procedures, tasks, and schedule for conducting the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) remedial investigation/feasibility study (RI/FS) for the 100-BC-2 operable unit in the 100 Area of the Hanford Site. The 100 Area is one of four areas at the Hanford Site that are on the US Environmental Protection Agency's (EPA) National Priorities List under CERCLA. The 100-BC-2 operable unit is one of two source operable units in the 100-B/C Area (Figure ES-1). Source operable units are those that contain facilities and unplanned release sites that are potential sources of hazardous substance contamination. The 100-BC-2 source operable unit contains waste sites that were formerly in the 100-BC-2, 100-BC-3, and 100-BC-4 operable units. Because of their size and geographic location, the waste sites from these two operable units were added to 100-BC-2. This allows for a more efficient and effective investigation of the remaining 100-B/C Reactor area waste sites. The investigative approach to waste sites associated with the 100-BC-2 operable unit are listed in Table ES-1. The waste sites fall into three general categories: high priority liquid waste disposal sites, low priority liquid waste disposal sites, and solid waste burial grounds. Several sites have been identified as candidates for conducting an IRM. Two sites have been identified as warranting additional limited field sampling. The two sites are the 116-C-2A pluto crib, and the 116-C-2C sand filter

    Much progress has been made in creating satellite products for tracking the pollutants ozone and NO2 in the troposphere. Yet, in mid-latitude regions where meteorological interactions with pollutants are complex, accuracy can be difficult to achieve, largely due to persistent layering of some constituents. We characterize the layering of ozone soundings and related species measured from aircraft over two ground sites in suburban Washington, DC (Beltsville, MD, 39.05N; 76.9W) and Baltimore (Edgewood, MD, 39.4N; 76.3W) during the July 2011 DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) experiment. First, we compare column-ozone amounts from the Beltsville and Edgewood sondes with data from overpassing satellites. Second, processes influencing ozone profile structure are analyzed using Laminar Identification and tracers: sonde water vapor, aircraft CO and NOy. Third, Beltsville ozone profiles and meteorological influences in July 2011 are compared to those from the summers of 2006-2010. Sonde-satellite offsets in total ozone during July 2011 at Edgewood and Beltsville, compared to the Ozone Monitoring Instrument (OMI), were 3 percent mean absolute error, not statistically significant. The disagreement between an OMIMicrowave Limb Sounder-based tropospheric ozone column and the sonde averaged 10 percent at both sites, with the sonde usually greater than the satellite. Laminar Identification (LID), that distinguishes ozone segments influenced by convective and advective transport, reveals that on days when both stations launched ozonesondes, vertical mixing was stronger at Edgewood. Approximately half the lower free troposphere sonde profiles have very dry laminae, with coincident aircraft spirals displaying low CO (80-110 ppbv), suggesting stratospheric influence. Ozone budgets at Beltsville in July 2011, determined with LID, as well as standard meteorological indicators, resemble those

    Testing and linkage to care are important determinants of hepatitis C virus (HCV) treatment effectiveness. Public health clinics serve populations at high risk of HCV. We investigated their potential to serve as sites for HCV testing, initiation of and linkage to HCV care. Cross-sectional study of patients accessing sexually transmitted infection (STI) care at the Baltimore City Health Department (BCHD) STI clinics, from June 2013 through April 2014 was conducted. Logistic regression was used to assess factors associated with HCV infection and specialist linkage to care. Between 24 June 2013 and 15 April 2014, 2681 patients were screened for HCV infection. Overall, 189 (7%) were anti-HCV positive, of whom 185 (98%) received follow-up HCV RNA testing, with 155 (84%) testing RNA positive. Of 155 RNA-positive individuals, 138 (89%) returned to the STI clinic for HCV RNA results and initial HCV care including counselling regarding transmission and harm reduction in alcohol, and 132 (85%) were referred to a specialist for HCV care. With provision of patient navigation services, 81 (52%) attended an offsite HCV specialist appointment. Alcohol use and lack of insurance coverage were associated with lower rates of specialist linkage (OR 0.4 [95% CI 0.1-0.9] and OR 0.4 [95% CI 0.1-0.9], respectively). We identified a high prevalence of HCV infection in BCHD STI clinics. With availability of patient navigation services, a large proportion of HCV-infected patients linked to off-site specialist care.

    The Old Midland Products site in Yell County, Arkansas was contaminated by hazardous chemicals from operations of a wood preserving plant. The U.S. Environmental Protection Agency (EPA) worked closely with the Arkansas Department of Pollution Control and Ecology (ADPCE) to select a cleanup plan to remediate the site, allowing unrestricted use by 1998. EPA and ADPCE actions consisted of: treating over 11 million gallons of contaminated surface water and lagoon liquids; employing a highly efficient, transportable incinerator to destroy more than 85,000 tons of contaminated soil and lagoon sludges over a short period of time; installing recovery wells to treat an estimated 450,000 gallons of contaminated ground water; and maintaining effective community relations with local residents to address their concerns and involve them in the cleanup process. The site serves as an example of how EPA, state agencies, and local residents can work together to restore the environment polluted by hazardous waste

    Ellefsen, Richard; Coffland, Bruce

    1987-01-01

    Low altitude, oblique and vertical color photography taken from EPA's Enviro-Pod Ka 85 camera system has provided the data for taking an inventory of building surface materials in a test area of downtown Baltimore. Photography was acquired from a gridded flight plan to provide views of all sides of buildings. Color, texture, and linear detail are employed in the photo interpretation aided by contextual reference to a classification of building construction type developed in an earlier study. The work could potentially support a materials inventory initiated by the National Acid Precipitation Assessment Program (NAPAP) by scientists from EPA, Geological Survey, and the Department of Energy. Initial results show the method to be viable. Discrete surface materials such as brick, both bare and painted, stone, and metal are identified.

  10. Description of Work for Drilling at the 183-DR Site in Support of the In Situ Gaseous Reduction Test

    Energy Technology Data Exchange (ETDEWEB)

    Thornton, Edward C.; Olsen, Khris B.; Schalla, Ronald

    2000-06-26

    In Situ Gaseous Reduction is a technology currently being developed by DOE for the remediation of soil waste sites contaminated with hexavalent chromium. Prior work suggests that a candidate for application of this approach is the 183-DR site at Hanford. However, deep vadose zone drilling is needed to verify the presence of a hexavalent chromium source and to determine the concentration levels and spatial distribution of contamination. This document presents the requirements associated with drilling one to two vadose zone boreholes at the 183-DR site to obtain this information. If hexavalent chromium is determined to be present at levels of at least 10 ppm in the vadose zone in one of the initial boreholes, this hole will be completed for gas injection and six additional gas extraction boreholes will be drilled and completed. This network will be used as a flowcell for performing a gas treatment test at the site.

The River Corridor scope is currently contractually assigned to Fluor Hanford, Bechtel Hanford, inc., DynCorp, and Pacific Northwest National Laboratory, and others. The purpose of this project specification is to provide an overall scoping document for the River Corridor Restoration volume, and to provide a link with the overall Hanford Site River Corridor scope. Additionally, this specification provides an integrated and consolidated source of information for the various scopes, by current contract, for the River Corridor Restoration Baseline. It identifies the vision, mission, and goals, as well as the operational history of the Hanford Site, along with environmental setting and hazards

  12. Present status of geological and geophysical work at selected nuclear power plant sites in Czechoslovakia

    International Nuclear Information System (INIS)

    In the last three years geological methods were used in Czechoslovakia to study several potential and approved sites for the construction of nuclear power plants. In the Blahutovice locality (northern Moravia) large-scale geophysical measurements have been carried out since 1982 whose objective is to identify microbumps and to determine their foci in the surrounds of the future nuclear power plant construction site. Similar measurements are being prepared for other localities, namely in eastern Bohemia and in Kecerovce in eastern Slovakia. In other localities changes in the intensity of earthquakes are studied caused by the detailed geological and hydrogeological situation. (Z.M.)

  15. ILK statement on the recommendations by the working group on procedures for the selection of repository sites

    International Nuclear Information System (INIS)

    The Working Group on Procedures for the Selection of Repository Sites (AkEnd) had been appointed by the German Federal Ministry for the Environment (BMU) to develop procedures and criteria for the search for, and selection of, a repository site for all kinds of radioactive waste in deep geologic formations in Germany. ILK in principle welcomes the attempt on the part of AkEnd to develop a systematic procedure. On the other hand, ILK considers the two constraints imposed by BMU inappropriate: AkEnd was not to take into account the two existing sites of Konrad and Gorleben and, instead, work from a so-called white map of Germany. ILK recommends to perform a comprehensive safety analysis of Gorleben and define a selection procedure including the facts about Gorleben and, in addition, to commission the Konrad repository as soon as possible. The one-repository concept established as a precondition by BMU greatly restricts the selection procedure. There are no technical or scientific reasons for such concept. ILK recommends to plan for separate repositories, which would also correspond to international practice. The geoscientific criteria proposed by AkEnd should be examined and revised. With respect to the site selection procedure proposed, ILK feels that procedure is unable to define a targeted approach. Great importance must be attributed to public participation. The final site selection must be made under the responsibility of the government or the parliament. (orig.)

    On-site disposal cells are in use and being considered at several U.S. Department of Energy (USDOE) sites as the final disposition for large amounts of waste associated with cleanup of contaminated areas and facilities. These facilities are typically developed with regulatory oversight from States and/or the US Environmental Protection Agency (USEPA) in addition to USDOE. The facilities are developed to meet design standards for disposal of hazardous waste as well as the USDOE performance based standards for disposal of radioactive waste. The involvement of multiple and different regulators for facilities across separate sites has resulted in some differences in expectations for performance assessments and risk assessments (PA/RA) that are developed for the disposal facilities. The USDOE-EM Office of Site Restoration formed a working group to foster improved communication and sharing of information for personnel associated with these Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) disposal cells and work towards more consistent assumptions, as appropriate, for technical and policy considerations related to performance and risk assessments in support of a Record of Decision and Disposal Authorization Statement. The working group holds teleconferences, as needed, focusing on specific topics of interest. The topics addressed to date include an assessment of the assumptions used for performance assessments and risk assessments (PA/RAs) for on-site disposal cells, requirements and assumptions related to assessment of inadvertent intrusion, DOE Manual 435.1-1 requirements, and approaches for consideration of the long-term performance of liners and covers in the context of PAs. The working group has improved communication among the staff and oversight personnel responsible for onsite disposal cells and has provided a forum to identify and resolve common concerns.

  20. Superfund at work: Hazardous waste cleanup efforts nationwide, fall 1992. (Lansdowne radioactive residence site profile)

    International Nuclear Information System (INIS)

    The fact sheet gave a general overview of the Superfund clean-up of a Lansdowne, PA house, the only residential site placed on the EPA's National Priorities List and the first non-federal radiation site cleaned up under Superfund. The basement of the house had been Dr. Dicran Kabakjian's unregulated radium processing laboratory from 1924 to 1944. The house and the soil surrounding it had to be completely cleared away because both were seriously contaminated with radon gas and gamma radiation. As a result, the EPA established the precedent for setting radiation levels in residential areas, applying more stringent levels than those set by the Uranium Mill Tailings Radiation Control Act of 1978

  1. A working group's conclusion on site specific flow and transport modelling

    International Nuclear Information System (INIS)

    This document suggests a strategy plan for groundwater flow and transport modelling to be used in the site specific performance assessment analysis of spent nuclear fuel disposal to be used for the site selection planned by the year 2000. Considering suggested general regulations in Finland, as well as suggested regulations in Sweden and the approach taken in recent safety assessment exercises conducted in these countries, it is clear that in such an analysis, in addition to showing that the proposed repository is safe, there exist needs to strengthen the link between field data, groundwater flow modelling and derivation of safety assessment parameters, and needs to assess uncertainty and variability. The suggested strategy plan builds on an evaluation of different approaches to modelling the groundwater flow in crystalline basement rock, the abundance of data collected in the site investigation programme in Finland, and the modelling methodology developed in the programme so far. It is suggested to model the whole system using nested models, where larger scale models provide the boundary conditions for the smaller ones

    tetramer octamer higher order. It is believed that multimer aggregation of lysozyme occurs by interaction at specific binding sites on the surface of the protein crystals. If the presence of discrete binding sites and the aggregation hypothesis is true, then it follows that the alteration of the binding site(s) should have significant effect on the measurements obtained during growth experiments. Site-directed mutagenesis allows the specific alteration of proteins by replacement, deletion or addition of specific amino acid residues. This report outlines the approach for this strategy and the progress made thus far toward that end.

    2011-01-01

    Many factors are associated with long sick leaves and therefore, reliance solely on disease-related factors can potentially underestimate sick leave durations. Here, we wanted to assess the association between the injury sites, work-related factors, and the length of sick leaves. Comprehensive medical legal reports of workers with pure minor musculoskeletal injuries were reviewed. 2029 reports of workers were included. 32.8% had sick leaves of less than a week in duration. Lower limb injuries were associated with longer sick leaves only in patients performing strenuous jobs. Public sector workers sustaining an injury at work and performing strenuous jobs were associated with longer sick leaves. Senior workers returned earlier to work, but age and gender were not strongly correlated with long sick leaves. There was a weak but significant association between sick leave duration and the period spent refraining from hobby activities, and almost all patients returned to their work before their hobbies.

    Koningsveld, Ernst; van der Grinten, Maarten; van der Molen, Henk; Krause, Frank

    2005-07-01

    Ground surface conditions on construction sites have an important influence on the health and safety of workers and their productivity. The development of an expert-based "working conditions evaluation" system is described, intended to assist site managers in recognising unsatisfactory ground conditions and remedying these. The system was evaluated in the period 2002-2003. The evaluation shows that companies recognize poor soil/ground conditions as problematic, but are not aware of the specific physical workload hazards. The developed methods allow assessment of the ground surface quality and selection of appropriate measures for improvement. However, barriers exist at present to wide implementation of the system across the industry. Most significant of these is that responsibility for a site's condition is not clearly located within contracting arrangements, nor is it a topic of serious negotiation. PMID:15892938

    2007-12-01

    The purpose of this project is to quantify the urban water cycle, with an emphasis on urban groundwater, using investigations at multiple spatial scales. The overall study focuses on the 171 sq km Gwynns Falls watershed, which spans an urban to rural gradient of land cover and is part of the Baltimore Ecosystem Study LTER. Within the Gwynns Falls, finer-scale studies focus on the 14.3 sq km Dead Run and its subwatersheds. A coarse-grid MODFLOW model has been set up to quantify groundwater flow magnitude and direction at the larger watershed scale. Existing wells in this urban area are sparse, but are being located through mining of USGS NWIS and local well data bases. Wet and dry season water level synoptics, stream seepage transects, and existing permeability data are being used in model calibration. In collaboration with CUAHSI HMF Geophysics, a regional-scale microgravity survey was conducted over the watershed in July 2007 and will be repeated in spring 2008. This will enable calculation of the change in groundwater levels for use in model calibration. At the smaller spatial scale (Dead Run catchment), three types of data have been collected to refine our understanding of the groundwater system. (1) Multiple bromide tracer tests were conducted along a 4 km reach of Dead Run under low-flow conditions to examine groundwater- surface water exchange as a function of land cover type and stream position in the watershed. The tests will be repeated under higher base flow conditions in early spring 2008. Tracer test data will be interpreted using the USGS OTIS model and results will be incorporated into the MODFLOW model. (2) Riparian zone geophysical surveys were carried out with support from CUAHSI HMF Geophysics to delineate depth to bedrock and the water table topography as a function of distance from the stream channel. Resistivity, ground penetrating radar, and seismic refraction surveys were run in ten transects across and around the stream channels. (3) A finer

  19. Migration of gases through fractured argillaceous rocks: experimental work at the Reskajeage Farm Quarry site, Cornwall

    International Nuclear Information System (INIS)

    The objective of the fieldwork in the Cornish slate site was to attempt in-situ testing of gas permeabilities of single fracture systems in the formation using a downhole packer. Complementary hydraulic studies at the same site are currently in process, conducted by B Watkins of Elcon Western (electrical) Ltd, Redruth. Two boreholes, BH2 and BH14 have been gas flow tested at depths between 9.85-13.30 m and 22.40-28.00 m, respectively, using oxygen-free nitrogen. Altogether 24 flow sections have been logged and continuously flow-tested over periods ranging from 1-10 hours. Seven of these flow sections were tested until steady-state flow conditions had been achieved, and at six of these levels rising/falling pressure tests were then conducted. Pressure decay tests have been performed at four test levels which had been logged as having little or no measurable gas flow. For both boreholes the recovered core has been fully logged for fracture and lithological variations, and the identified flow sections have been correlated with these logs. In the case of BH14, successful impression packering of fracture/vein patterns in the borehole wall from 5.01-18.02 m depth has been made. The fractures recorded in the impressions have been correlated with fractures logged in the recovered core over the same section of the borehole. (author)

  20. The role of historical operations information for supporting remedial investigation work at the former Harshaw Chemical Site

    International Nuclear Information System (INIS)

    In the early stages of hazardous, toxic, and radioactive waste (HTRW) site investigations, basic record searches are performed to help direct the agencies investigating contaminated sites to areas of concern and to identify contaminants of interest (COI). Plans developed on the basis of this preliminary research alone are often incomplete and result in unexpected discoveries either while in the field investigating the site or after the reports have been written. Many of the sites investigated under the Formerly Utilized Sites Remedial Action program (FUSRAP) have complex histories that are slowly uncovered over the life of the project. Because of programmatic constraints, nuances of these sites are often discovered late in their programs and result in increased expenditures in order to fully characterize the site, perform a robust feasibility study, and recommend appropriate alternatives for remediation. By identifying resources for public records, classified records, historic aerial photographs, and other sources of site-specific historical information, a process can be established to optimize the collection of information and to develop efficient and complete project plans. In many cases, interviews with past site employees are very useful tools. In combining what is found in the records, observed on historic aerial photographs, and heard from former employees and family members, teams investigating these sites can begin to compile sound and more complete conceptual site models (CSMs). The former Harshaw Chemical Site (HCS) illustrates this discovery process. HCS is part of FUSRAP. Preliminary investigations by the US Department of Energy (DOE) in the 1970s provided an initial CSM of activities that had taken place that may have resulted in contamination. The remedial investigation (RI) conducted by the US Army Corps of Engineers (USACE) was designed around this CSM. The RI work, however, identified a number of site conditions that were unexpected, including new

    LaFreniere, L. M.

    2006-07-11

    This ''Work Plan'' outlines the scope of work for a targeted groundwater sampling investigation and monitoring well installation at Barnes, Kansas. This activity is being conducted at the request of the Kansas Department of Health and Environment (KDHE), in accordance with the intergovernmental agreement between the KDHE and the Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA). Data resulting from the proposed work will be used to determine the hydraulic gradient near the former CCC/USDA facility, delineate the downgradient carbon tetrachloride plume, and determine additional monitoring requirements at Barnes. The overall goal is to establish criteria for monitoring leading to potential site reclassification. The proposed work will be performed on behalf of the CCC/USDA by the Environmental Science Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE). The Farm Service Agency of the USDA has entered into an interagency agreement with DOE, under which Argonne provides technical assistance with environmental site characterization and remediation at former CCC/USDA grain storage facilities. Argonne issued a ''Master Work Plan'' (Argonne 2002) to provide general guidance for all investigations at former CCC/USDA facilities in Kansas. The ''Master Work Plan'', approved by the KDHE, contains the materials common to investigations at all locations in Kansas. This document must be consulted for the complete details of plans for this work associated with the former CCC/USDA facility at Barnes.

  2. Comprehensive character of geodesy work on nuclear power plant sites and examples of special efforts

    International Nuclear Information System (INIS)

    The distribution is described of investment in geodesy and cartography work, and the necessity is pointed out of quality instrumentation as well as of the establishment of a unified data bank. An organization is proposed of geodesy work that should secure improved construction control beginning with the project design, maximum utilization of instrumentation and the production of a standard application software. The Research Institute of Geodesy, Topography and Cartography participated in the preparation work on the construction of the Temelin nuclear power plant. It provided a set of geodesy technologies for the construction of WWER-1000 reactors, it performed deformation measurements of the containment, cooling towers and the building structure in the turbo-generator area. It compiled a methodology for checking the shape of 155 m high cooling towers. The objectives of the measurement and the requirements on the accuracy of the measurement are explained. The forward intersection method was selected as the main method, using the initially proposed network, while photogrammetry was used as a complementary method. (E.J.). 3 figs., 9 refs

    Inhomogeneous percolation, for its closer relationship with real-life, can be more useful and reasonable than homogeneous percolation to illustrate the critical phenomena and dynamical behaviour of complex networks. However, due to its intricacy, the theoretical framework of inhomogeneous percolation is far from being complete and many challenging problems are still open. In this paper, we first investigate inhomogeneous site percolation on Bethe Lattices with two occupation probabilities, and then extend the result to percolation with m occupation probabilities. The critical behaviour of this inhomogeneous percolation is shown clearly by formulating the percolation probability with given occupation probability p, the critical occupation probability , and the average cluster size where p is subject to . Moreover, using the above theory, we discuss in detail the diffusion behaviour of an infectious disease (SARS) and present specific disease-control strategies in consideration of groups with different infection probabilities.

    Risk-based corrective action programmes for contaminated gas works sites focus on organic and inorganic compounds posing potential health effects to humans and/or ecological receptors. These programmes include an understanding of the nature and extent of contamination, transport and fate in appropriate pathways, toxicological effects to human health and the environment, and remedial options. Potential risk-generating substances at gas works sites in the United Kingdom and Canada include coal tar and tar residues, spent oxides, sulphur compounds, and heavy metals. Organic compounds found in coal tar can include monocyclic (e.g. benzene, phenols) and polycyclic (e.g. naphthalene, chrysene) aromatic hydrocarbons. Tar and some of its components are carcinogenic. Metals and sulphur may be present at gas works sites. Sulphur contaminated soils can have depressed pH, which can lead to metals mobilization, and contaminated groundwater. Metals can be of concern in soils and groundwater, as can spent oxides from town gas manufacturing. These may include varying proportions of cyanide, either as relatively immobile complexed ferro-ferric cyanide (i.e. blue billy), or as more mobile and toxic free cyanide. Aquifers and surface water bodies can be pathways for dissolved metals or organic compounds with elevated aqueous solubilities. Some components of coal tar have appreciable vapour pressures and may emit odours if in near-surface soils, pathways exist via dermal contact or ingestion. Case histories from two coal gasification sites, one in the UK and one in Canada, are presented and discussed. 3 refs., 1 tab.

  6. RCRA Facility investigation/corrective measures study work plan for the 100-DR-2 operable unit, Hanford Site, Richland, Washington

    International Nuclear Information System (INIS)

    This work plan establishes the operable unit setting and the objectives, approach, tasks, and schedule for conducting the Resource Conservation Recovery Act facility investigation/corrective measure study (RFI/CMS) for the 100-DR-2 Operable Unit in the 100 Area of the Hanford Site. This work plan is intended to cover the entire RFI/CMS program, but it is focused on limited field investigation (LFI) activities. The 100 Area is one of four areas at the Hanford Site that are on the U.S. Environmental Protection Agency's (EPA) National Priorities List under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980. The 100-DR-2 Operable Unit is one of two remaining source operable units in the 100 D/DR Area. Source operable units are those that contain facilities and unplanned release sites that are potential sources of hazardous substance contamination. In order to more efficiently manage the environmental restoration of the 100 D/DR Area, 100-DR-3 was incorporated into 100-DR-2. The 100-DR-2 contains liquid, sludge, and solid waste units that were used to support the operation of the DR Reactor. The 100-DR-3 mainly consists of solid waste burial grounds, which are presently on the interim remedial measure (IRM) pathway. The approach described in this work plan is based on the Hanford Past-Practice Strategy. This strategy streamlines the past-practice remedial action process with a bias for action through optimizing the use of interim actions. This approach culminates with decisions of final remedies on both an operable unit and 100 Area scale. The pathway selected during the scoping process for the high-priority liquid waste sites and solid waste burial grounds in the 100-DR-2 Operable Unit is the IRM pathway

  8. Work plan for preliminary investigation of organic constituents in ground water at the New Rifle site, Rifle, Colorado. Revision 2

    International Nuclear Information System (INIS)

    A special study screening for Appendix 9 (40 CFR Part 264) analytes identified the New Rifle site as a target for additional screening for organic constituents. Because of this recommendation and the findings in a recent independent technical review, the US Department of Energy (DOE) has requested that the Technical Assistance Contractor (TAC) perform a preliminary investigation of the potential presence of organic compounds in the ground water at the New Rifle Uranium Mill Tailings Remedial Action (UMTRA) Project site, Rifle, Colorado. From 1958 to 1972, organic chemicals were used in large quantities during ore processing at the New Rifle site, and it is possible that some fraction was released to the environment. Therefore, the primary objective of this investigation is to determine whether organic chemicals used at the milling facility are present in the ground water. The purpose of this document is to describe the work that will be performed and the procedures that will be followed during installation of ground water well points at the New Rifle site. The selection of analytes and the procedures for collecting ground water samples for analysis of organic constituents are also described

  13. Plutonium working group report on environmental, safety and health vulnerabilities associated with the department's plutonium storage. Volume II, part 9, Oak Ridge Site working group assessment team report

    International Nuclear Information System (INIS)

    The objective of the Plutonium Environmental Safety and Health (ES ampersand H) Vulnerability Assessment at the Oak Ridge (OR) Site was to conduct a comprehensive assessment of the ES ampersand H vulnerabilities arising from the storage and handling of its current plutonium holdings. The term open-quotes ES ampersand H Vulnerabilityclose quotes is defined for the purpose of this project to mean conditions or weaknesses that could lead to unnecessary or increased radiation exposure of workers, release of radioactive materials to the environment, or radiation exposure to the public. This assessment was intended to take a open-quotes snap-shotclose quotes of Oak Ridge National Laboratory (ORNL) and the Y-12 Plant's plutonium holdings and associated ES ampersand H vulnerabilities in the time frame of June 1 994. This vulnerability assessment process began with the OR Site Assessment Team (SAT) generating a self-assessment report including proposed vulnerabilities. The SAT identified 55 facilities which contain plutonium and other transuranics they considered might be in-scope for purposes of this study. The Working Group Assessment Team (WGAT), however, determined that 37 of the facilities actually contained only out-of-scope material (e.g., transuranic material not colocated with plutonium or transuranic (TRU) waste). The WGAT performed an independent assessment of the SATs report, conducted facility walkdowns, and reviewed reference documents such as Safety Analysis Reports (SARs), Operational Safety Requirements (OSRs), emergency preparedness plans, and procedures. The results of the WGAT review and open-quotes walkdownsclose quotes (a term as used here incorporating tours, document reviews, and detailed discussions with cognizant personnel) are discussed in Section 3.0. The ES ampersand H vulnerabilities that were identified are documented in Appendix A

    Liverman, James L.

    1978-04-01

    An allocation of naphtha feedstock up to 2,186,000 barrels per year to Baltimore Gas and Electric Company (BG and E) to operate its synthetic natural gas (SNG) facility is being considered. The allocation would enable BG and E to produce 10,800,000 mcf of SNG during a 180 day period. Operation of the plant at design capacity is expected to result in annual pollution emissions as follows: 626.4 tons of sulfur oxides, 168.5 tons of nitrogen oxides and 21.6 tons of particulate matter. Incremental emissions due to plant operations relative to existing emissions in Baltimore County are less than 1%. All Federal and State air quality standards should be met. Treated effluent is to be discharged into the Patapasco River where the environmental impacts are not expected to be significant. The SNG facility has been designed to be in compliance with all applicable Federal, State and local effluent standards. Water consumption requirements of 335,000 gallons per day are not expected to significantly tax the area's water resources. Sound generated by the SNG facility will be inaudible or imperceptible. All other operational impacts on land use, population, visual quality, roadways, community facilities and services and ecological systems were judged to be minimal. Environmental impacts resulting from various alternatives ranging from full allocation through denial of an allocation are discussed.

    Full Text Available and revitalization of building heritage of the territory of contemporary Serbia includes numerous late classical archaeological sites. In spite of the efforts oriented to their adequate protection and presentation, the up-to-date conservation practice has faced various problems, particularly those related to the conservation of the brickwork. Problems especially emerge when the need for the new bricks arises, due to their different quality in comparison with those of historical ones. The problem is emphasized by the fact that the recent conservation process, practiced in this region, has not been followed by any qualitative analysis, either of historical or contemporary bricks. Therefore, the results of the recent investigation focused on characterization of late antique bricks from the region have been presented in this paper, seen in the context of conservation works.

  20. Performance allocation traceable to regulatory criteria as applied to site characterization work at the Basalt Waste Isolation Project

    International Nuclear Information System (INIS)

    The Basalt Waste Isolation Project has developed a method for defining in detail the work required to demonstrate the feasibility of emplacing and providing for the safe isolation of nuclear wastes in a repository in the deep basalts at the Hanford Site near Richland, Washington. Criteria analysis allows the identification of areas of significant technical uncertainty or controversy that can be highlighted as issues. A preliminary analysis has been conducted, which, by identifying key radionuclides and allocating performance among the multiple barriers in a repository constructed in a basalt, allows the design and development testing activities at the Basalt Waste Isolation Project to be put into perspective. Application of sophisticated uncertainty analysis techniques will allow refinements in the analysis to be made and to further guide characterization and testing activities. Preliminary results suggest that a repository constructed in basalt will provide for the safe isolation of nuclear wastes in a cost-effective and reliable manner with a high degree of confidence

    Full Text Available We build upon much of the accumulated knowledge of the widely used SLEUTH urban land change model and offer advances. First, we use SLEUTH’s exclusion/attraction layer to identify and test different urban land cover change drivers; second, we leverage SLEUTH’s self-modification capability to incorporate a demographic model; and third, we develop a validation procedure to quantify the influence of land cover change drivers and assess uncertainty. We found that, contrary to our a priori expectations, new development is not attracted to areas serviced by existing or planned water and sewer infrastructure. However, information about where population and employment growth is likely to occur did improve model performance. These findings point to the dominant role of centrifugal forces in post-industrial cities like Baltimore, MD. We successfully developed a demographic model that allowed us to constrain the SLEUTH model forecasts and address uncertainty related to the dynamic relationship between changes in population and employment and urban land use. Finally, we emphasize the importance of model validation. In this work the validation procedure played a key role in rigorously assessing the impacts of different exclusion/attraction layers and in assessing uncertainty related to population and employment forecasts.

  5. Remedial Investigation/Feasibility Study Work Plan for the 200-UP-1 Groundwater Operable Unit, Hanford Site, Richland, Washington

    International Nuclear Information System (INIS)

    This work plan identifies the objectives, tasks, and schedule for conducting a Remedial Investigation/Feasibility Study for the 200-UP-1 Groundwater Operable Unit in the southern portion of the 200 West Groundwater Aggregate Area of the Hanford Site. The 200-UP-1 Groundwater Operable Unit addresses contamination identified in the aquifer soils and groundwater within its boundary, as determined in the 200 West Groundwater Aggregate Area Management Study Report (AAMSR) (DOE/RL 1992b). The objectives of this work plan are to develop a program to investigate groundwater contaminants in the southern portion of the 200 West Groundwater Aggregate Area that were designated for Limited Field Investigations (LFIs) and to implement Interim Remedial Measures (IRMs) recommended in the 200 West Groundwater AAMSR. The purpose of an LFI is to evaluate high priority groundwater contaminants where existing data are insufficient to determine whether an IRM is warranted and collect sufficient data to justify and implement an IRM, if needed. A Qualitative Risk Assessment (QRA) will be performed as part of the LFI. The purpose of an IRM is to develop and implement activities, such as contaminant source removal and groundwater treatment, that will ameliorate some of the more severe potential risks of groundwater contaminants prior to the RI and baseline Risk Assessment (RA) to be conducted under the Final Remedy Selection (FRS) at a later date. This work plan addresses needs of a Treatability Study to support the design and implementation of an interim remedial action for the Uranium-99 Tc-Nitrate multi-contaminant IRM plume identified beneath U Plant

  6. DOE's Environmental Management Site-Specific Advisory Board: The Roles, Work, and Assessment of the Constituent Local Boards - 13587

    International Nuclear Information System (INIS)

    The charter for the Department of Energy's Environmental Management (EM) Site-Specific Advisory Board (SSAB) was approved under the Federal Advisory Committee Act (FACA) in 1994. With a unique mandate to provide public input on issues associated with the cleanup of nuclear legacy sites in the U.S., the EM SSAB comprises eight local boards, which are based at major EM sites. While each board is unique to the community in which it is located and reflects the diversity of the local population, the boards are governed by FACA, related regulations, and DOE policies that are intended to standardize agency advisory board operations. The EM SSAB local boards are made up of a diverse group of citizens who want to understand the mission and goals of the EM program and to help EM achieve those goals for the benefit of their communities. Some are quite passionate about their mission; others need to be coaxed into active participation. Maintaining productive relationships and a supportive environment for effective board operations is the challenge of board management for DOE EM and the board members themselves. DOE draws on research findings and best practices literature from academics and practitioners in the field of public involvement in its board management practices. The EM SSAB is also evaluated annually under the law to ensure that the investment of taxpayer dollars in the board is warranted in light of the contributions of the board. Further evaluation takes place at the agency and site levels in order to identify what aspects of board functioning the agency and board members find important to its success and to address areas where improvement is needed. Board contributions, compliance factors, and measurable outcomes related to board products and process areas are key to agency commitment to ongoing support of the boards and to participant satisfaction and thus continued member involvement. In addition to evaluation of these factors in improving board effectiveness

    This study investigated the effectiveness of labeling foods with the Choices nutrition logo on influencing cafeteria menu selection and the behavioral determinants of menu choices in work site cafeterias in the Netherlands. A cluster randomized controlled trial was conducted. Intervention cafeterias (n=13), where the Choices logo was used to promote healthier eating for a 3-week period, were compared with control cafeterias (n=12), which offered the same menu without the logo. Sales data were collected daily for 9 weeks, from March to May 2009. In addition, employees from one intervention and one control company completed an online questionnaire at baseline and after the intervention (n=368) in which the behavioral determinants of food choice (ie, attitude, self-efficacy, and intention) and logo use were measured. Generalized estimating equation analyses, χ² tests, t tests and linear regression analyses were performed. No nutritionally meaningful intervention effects were found in the sales of sandwiches, soups, snacks, fruit, and salads. Also, no significant differences in behavioral determinants were found. "Intention to eat healthier" and "paying attention to product information" were positively associated with self-reported consumption of foods with the Choices logo at lunch. The intervention did not have a significant effect on employees' lunchtime food choices. Labeling healthy choices might be useful for health-conscious employees in the volitional phase of behavior change. Further research should focus on the possible health benefits of menu reformulation in the catering sector. PMID:21185975

    The East Tennessee Technology Park Site-Wide Residual Contamination Remedial Investigation Work Plan (DOE 2004) describes the planned fieldwork to support the remedial investigation (RI) for residual contamination at the East Tennessee Technology Park (ETTP) not addressed in previous Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) decisions. This Addendum describes activities that will be conducted to gather additional information in Zone 1 of the ETTP for groundwater, surface water, and sediments. This Addendum has been developed from agreements reached in meetings held on June 23, 2010, August 25, 2010, October 13, 2010, November 13, 2010, December 1, 2010, and January 13, 2011, with representatives of the U. S. Department of Energy (DOE), U. S. Environmental Protection Agency (EPA), and Tennessee Department of Environment and Conservation (TDEC). Based on historical to recent groundwater data for ETTP and the previously completed Sitewide Remedial Investigation for the ETTP (DOE 2007a), the following six areas of concern have been identified that exhibit groundwater contamination downgradient of these areas above state of Tennessee and EPA drinking water maximum contaminant levels (MCLs): (1) K-720 Fly Ash Pile, (2) K-770 Scrap Yard, (3) Duct Island, (4) K-1085 Firehouse Burn/J.A. Jones Maintenance Area, (5) Contractor's Spoil Area (CSA), and (6) Former K-1070-A Burial Ground. The paper presents a brief summary of the history of the areas, the general conceptual models for the observed groundwater contamination, and the data gaps identified.

    In order to utilize satellite-based aerosol measurements for the determination of air quality, the relationship between aerosol optical properties (wavelength-dependent, column-integrated extinction measured by satellites) and mass measurements of aerosol loading (PM2.5 used for air quality monitoring) must be understood. This connection varies with many factors including those specific to the aerosol type, such as composition, size and hygroscopicity, and to the surrounding atmosphere, such as temperature, relative humidity (RH) and altitude, all of which can vary spatially and temporally. During the DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality) project, extensive in-situ atmospheric profiling in the Baltimore, MD-Washington, DC region was performed during fourteen flights in July 2011. Identical flight plans and profile locations throughout the project provide meaningful statistics for determining the variability in and correlations between aerosol loading, composition, optical properties and meteorological conditions. Measured water-soluble aerosol mass was composed primarily of ammonium sulfate (campaign average of 32 %) and organics (57 %). A distinct difference in composition was observed with high-loading days having a proportionally larger percentage of ammonium sulfate (up to 49 %) due to transport from the Ohio River Valley. This composition shift caused a change in the aerosol water-uptake potential (hygroscopicity) such that higher relative contributions of ammonium sulfate increased the bulk aerosol hygroscopicity. These days also tended to have higher relative humidity causing an increase in the water content of the aerosol. Conversely, low aerosol loading days had lower ammonium sulfate and higher black carbon contributions causing lower single scattering albedos (SSAs). The average black carbon concentrations were 240 ng m-3 in the lowest 1 km decreasing to 35 ng m-3

  18. Superfund at work: Hazardous waste cleanup efforts nationwide, spring 1993 (Radium Chemical Site profile, Queens, New York)

    International Nuclear Information System (INIS)

    The Radium Chemical hazardous waste site in Queens, New York was contaminated with radium, posing a grave potential threat to the community. The US Environmental Protection Agency (EPA) used the Superfund program to design a long-term cleanup for the site using input from citizens and the business community. Superfund staff: Mobilized a quick cleanup action to remove 10,000 small containers of radium; Developed a streamlined approach to long-term cleanup; Secured the site to reduce the possibility of radiation exposure to the local residents; Cooperated with the community to design a well-organized emergency response plan; and Educated local citizens about site hazards, incorporating community concerns into the cleanup process. The Radium Chemical site is a clear example of EPA's effective management and problem-solving strategies at Superfund sites

    The City of Baltimore is utilizing hot water produced from waste fueled boilers cogenerating electricity to supply heat to Cherry Hill a large public housing project, five schools, a nearby hospital and some commercial and industrial users. An eight inch pipe loop will deliver water at a temperature of 250 Fahrenheit from which smaller pipes will connect to heat exchangers in individual building. Most buildings will use hot water for circulation although a few will use converters to produce low temperature steam. The timing is fortuitous, in that the existing heating system is old and is scheduled for renovation. The money will be used for certain retrofit and connection costs rather than to install new boilers. An additional heat load island has been identified known as Hopkins-East Baltimore. This area is an urban renewal area containing seven public housing projects, five public schools, the city jail, John Hopkins hospital and Medical school, private housing and several other institutions. These two areas are good for early start district heating projects, ultimately a still larger system seems feasible.

    Tooey, Mary Joan (M.J.)

    2010-01-01

    Setting: The Health Sciences and Human Services Library (HS/HSL), University of Maryland, Baltimore (UMB), is located in an urban environment on the west side of downtown Baltimore. Founded in 1813, the library opened its current building in 1998 and is one of the largest health sciences libraries in the United States, with 6 floors and over 180,000 gross square and 118,000 net assignable square feet (NASF). Project: The initial discussions in late 2005 involved moving campus offices into the library. Almost immediately, it was recognized that a much larger renovation was needed due to the scope of the work. The vice president for academic affairs, the library executive director, and campus planners agreed that if the renovation was done thoughtfully, multiple needs could be met, including new office spaces, better user spaces, and synergy with the new campus center being built next door. Planning: The planning, design, and construction process was multifaceted and on a fast track. Although the final piece of the renovation was completed in June 2009, the majority of the planning, design, and construction took place between March 2006 and June 2008. All tenants were involved with office design. Library staff were involved in designing the public spaces and planning the strategy for weeding and shifting. Outcomes: Approximately 8,000 NASF was reallocated to new office space from shelving space, amounting to approximately 6.7% of the building NASF and approximately 10.6% of the public space in the building. The majority of new offices in the building report to the same vice president and are student focused and service oriented, with similar missions to that of the library resulting in a very harmonious cohabitation. Additional units with these missions and reporting structure are located in the new campus center, creating a synergy between the two buildings. PMID:20098653

    Although work-site factors have been shown to be a consistent predictor of burnout, the importance of mindfulness and values-based processes among addiction counselors has been little examined. In this study, we explored how strongly experiential avoidance, cognitive fusion, and values commitment related to burnout after controlling for well-established work-site factors (job control, coworker support, supervisor support, salary, workload, and tenure). We conducted a cross-sectional survey among 699 addiction counselors working for urban substance abuse treatment providers in six states of the United States. Results corroborated the importance of work-site factors for burnout reduction in this specific population, but we found that mindfulness and values-based processes had a stronger and more consistent relationship with burnout as compared with work-site factors. We conclude that interventions that target experiential avoidance, cognitive fusion, and values commitment may provide a possible new direction for the reduction of burnout among addiction counselors.

    The U.S. Army Corps of Engineers (USACE) - Philadelphia District is conducting an environmental restoration at the DuPont Chambers Works in Deepwater, New Jersey under the Formerly Utilized Sites Remedial Action Program (FUSRAP). Discrete locations are contaminated with natural uranium, thorium-230 and radium-226. The USACE is proposing a preferred remedial alternative consisting of excavation and offsite disposal to address soil contamination followed by monitored natural attenuation to address residual groundwater contamination. Methods were developed to quantify the error associated with contaminant volume estimates and use mass balance calculations of the uranium plume to estimate the removal efficiency of the proposed alternative. During the remedial investigation, the USACE collected approximately 500 soil samples at various depths. As the first step of contaminant mass estimation, soil analytical data was segmented into several depth intervals. Second, using contouring software, analytical data for each depth interval was contoured to determine lateral extent of contamination. Six different contouring algorithms were used to generate alternative interpretations of the lateral extent of the soil contamination. Finally, geographical information system software was used to produce a three dimensional model in order to present both lateral and vertical extent of the soil contamination and to estimate the volume of impacted soil for each depth interval. The average soil volume from all six contouring methods was used to determine the estimated volume of impacted soil. This method also allowed an estimate of a standard deviation of the waste volume estimate. It was determined that the margin of error for the method was plus or minus 17% of the waste volume, which is within the acceptable construction contingency for cost estimation. USACE collected approximately 190 groundwater samples from 40 monitor wells. It is expected that excavation and disposal of

  7. Aerial radiometric and magnetic reconnaissance survey of Baltimore, Washington, and Richmond quadrangles. Final Report. Volume 1. Instrumentation and methods

    International Nuclear Information System (INIS)

    Instrumentation and methods used for a DOE-sponsored high-sensitivity, aerial gamma-ray spectrometer and magnetometer survey of the Baltimore, Washington, and Richmond NTMS, 1:250,000 scale quadrangles are described. The objective of the work was to define areas showing surface indications of a generally higher uranium content where detailed exploration of uranium would most likely be successful. A DC-3 aircraft equipped with a gamma-ray spectrometer using nine large-volume NaI detectors, two 400-channel analyzers, and ancillary geophysical and electronic equipment was used. The system was calibrated using DOE calibration facilities at Grand Junction, Colorado, and Lake Mead, Arizona. Gamma-ray spectrometric data were processed to correct for variations in atmospheric, flight, and instrumental conditions and were statistically evaluated to remove the effects of surface geologic variations. The resulting first-priority uranium anomalies (showing simultaneously valid eU, eU/eTh, and eU/K anomalies) were interpreted to evaluate their possible origin and significance. Results of the interpretation, along with significance factor profile maps, stacked profiles, histograms, and statistical summary tables, are presented in separate individual quadrangle reports issued as Volumes 2-A through 2-C of this final report. It is concluded that, although the probability of finding large economic uranium deposits (as judged by today's standards) is not considered great based on present known occurrences, the strongest first-priority uranium anomalies deserve follow-up investigation to determine their cause and to evaluate further the uranium potential of the area

  9. Regulatory examination of the radiation-hygienic situation at Sites of Temporary Storage in North-West Russia prior to the beginning of major spent fuel removal works

    International Nuclear Information System (INIS)

    The paper describes a regulatory project carried out, under a collaborative agreement between the Federal Medical-Biological Agency of the Russian Federation (FMBA) and the Norwegian Radiation Protection Authority (NRPA), by the Institute of Biophysics (Technical Support Organisation to FMBA) and western specialists. The project is one several addressing aspects of the management of spent fuel and radioactive waste at Sites of Temporary Storage (STSs) operated by Federal Enterprise SevRAO at Andreeva Bay and Gremikha on the Kola Peninsula in North-West Russia, and the decommissioning of the sites. Industrial and regulatory projects are addressing options for removing spent submarine fuel currently stored in poor conditions at the sites and moving it to more appropriate storage facilities. The work described in this paper was to review and collate independent data on the current radiation situation and radiation control in the areas at and around the sites. The project has the ultimate objectives to develop norms and standards and supporting regulatory guidance for application during and upon completion of rehabilitation of Andreeva Bay and Gremikha, and this work provides a 'baseline' of radiation conditions, before operations begin to remove the spent fuel. The examination identified and prioritised areas of contamination on and around the sites in terms of their current significance for the safety and health of workers and the public and their possible future significance for the environment and potential future users of the sites. Some areas on the sites had high dose rates - up to about 140 μSv/h in Andreeva Bay and 8500 μSv/h in Gremikha - due to contamination from past spent fuel storage practices. Although there do not appear currently to be areas of severe contamination outside the sites, some of the contamination on-site is in forms that will migrate with time, for example in streams and marine sediments.

    Disparity between watershed erosion rates and downstream sediment delivery has remained an important theme in geomorphology for many decades, with the role of floodplains in sediment storage as a common focus. In the Piedmont Province of the eastern USA, upland deforestation and agricultural land use following European settlement led to accumulation of thick packages of overbank sediment in valley bottoms, commonly referred to as legacy deposits. Previous authors have argued that legacy deposits represent a potentially important source of modern sediment loads following remobilization by lateral migration and progressive channel widening. This paper seeks to quantify (1) rates of sediment remobilization from Baltimore County floodplains by channel migration and bank erosion, (2) proportions of streambank sediment derived from legacy deposits, and (3) potential contribution of net streambank erosion and legacy sediments to downstream sediment yield within the Mid-Atlantic Piedmont. We calculated measurable gross erosion and deposition rates within the fluvial corridor along 40 valley segments from 18 watersheds with drainage areas between 0.18 and 155 km2 in Baltimore County, Maryland. We compared stream channel and floodplain morphology from lidar-based digital elevation data collected in 2005 with channel positions recorded on 1:2400 scale topographic maps from 1959-1961 in order to quantify 44-46 years of channel change. Sediment bulk density and particle size distributions were characterized from streambank and channel deposit samples and used for volume to mass conversions and for comparison with other sediment sources. Average annual lateral migration rates ranged from 0.04 to 0.19 m/y, which represented an annual migration of 2.5% (0.9-4.4%) channel width across all study segments, suggesting that channel dimensions may be used as reasonable predictors of bank erosion rates. Gross bank erosion rates varied from 43 to 310 Mg/km/y (median = 114) and were

    Bolden, Shenell L. T.

    The purpose of this exploratory study was to examine key stakeholders' perceptions of the current Baltimore City Public Schools' (BCPS) sex education curriculum and to gain insight into how they believe the curriculum could be modified to be more effective. A mixed methods approach using qualitative and quantitative data collection consisting of a survey, focus group interview, and individual interviews was conducted to gather information on stakeholders' perceptions. The stakeholders included: (1) former students who received their sex education courses in the Baltimore City Public School system (BCPS); (2) teachers in BCPS who were affiliated with the sex education curriculum; (3) health care professionals who screened and/or treated East Baltimore City residents for a sexually transmitted disease (STD) and; (4) one policy maker who was responsible for creating sex education curriculum at the national level. Analysis of the quantitative data from former Baltimore City Public School students revealed a general satisfaction with the current sex education curriculum. However, qualitative data from the same group of stakeholders revealed several changes they thought should be implemented into the program in an effort to improve the current curriculum. Findings from the other groups after qualitative analysis of the interviews suggest three major themes in support of curriculum change: (1) a blended curriculum that integrates both the cognitive and affective learning domains; (2) knowledge of prevention of STD's and pregnancy; and (3) authentic teaching and learning. Results from this study strongly suggest that the Baltimore City Public School system is apathetic to the sexual health needs of students and, therefore, is inadvertently contributing to the high rate of sexually transmitted diseases among young people. Keywords: Abstinence, Affective domain, Indoctrination, Behavior Modification, Cognitive domain, Sex education curriculum, Sexually Transmitted Diseases.

    2016-01-01

    Heat response plans are becoming increasingly more common as US cities prepare for heat waves and other effects of climate change. Standard elements of heat response plans exist, but plans vary depending on geographic location and distribution of vulnerable populations. Because heat events vary over time and affect populations differently based on vulnerability, it is difficult to compare heat response plans and evaluate responses to heat events. This article provides an overview of the Baltimore City heat response plan, the Code Red program, and discusses the city's response to the 2012 Ohio Valley/Mid Atlantic Derecho, a complex heat event. Challenges with and strategies for evaluating the program are reviewed and shared. PMID:27081886

  16. A review of seismotectonic frame work of Indian subcontinent: a prelude for site selection of nuclear power plants

    International Nuclear Information System (INIS)

    A heterogeneous milieu of endogenous factors interacting with globally generated stress fields divides the Indian shield into different provinces with distinctive seismic signatures and variable patterns of seismicity. These provinces are in the nature of broad belts of relatively much enhanced seismic activity and include the Kutch Rift Zone (KRZ), the Belt of Active Rifts (BARS) along the western continental borders, Son-Narmada-Tapati lineament (SONATA), parts of the eastern pericontinental Shillong Plateau, parts of the Eastern Continental margin and the Idukki - Munnar region of the Western Ghats in central Kerala. The regions of the shield outside these belts are possibly under a state of steady-state stability where localized transient mechanisms, as for example pore-pressure changes, can upset the steady-state stability especially of weak faults and generate earthquakes. Such a heterogeneous seismic milieu needs to be evaluated during site selection by enlarging the database provided by historical record of earthquakes and surface geological maps, on which reliance is based in current practices, with an integrated geological - geophysical approach. This may ensure a state-of-art approach to site evaluation and provide a firmer database to constrain site selection and determine several engineering parameters with consequent cost benefits. Such an approach to site selection can be easily implemented today due to the vastly expanded facilities that have been built up in India for seismological investigations and researches in the Post-1993 Latur Earthquake period and enormous expertise that have been built up among several institutions to upgrade geophysical technology. These investigations, would be unique in its content to different areas of candidate sites based on their geological setting and to implement them and monitor the selection of sites, in a reasonable time frame, the Nuclear Power Corporation of India (NPCIL) may have to generate a new

  17. Proposed training program for construction personnel involved in remedial action work at sites contaminated by naturally occurring radionuclides

    International Nuclear Information System (INIS)

    Many sites used during the early days of the US atomic energy program are contaminated with radionuclides of the primordial decay chains (uranium, thorium, and actinium series). This contamination consists of residues resulting from refining and processing uranium and thorium. Preparation of these sites for release to unrestricted private use will involve the assistance of construction workers, many of whom have limited knowledge of the hazards associated with radioactive materials. Therefore, there is a need to educate these workers in the fundamentals of radioactive material handling to minimize exposures and possible spread of contamination. This training should disseminate relevant information at an appropriate educational level and should instill a cautious, common-sense attitude toward the handling of radioactive materials. The training should emphasize basic information concerning environmental radiation within a context of relative risk. A multi-media format, including colorful visual aids, demonstration, and discussion, should be used to maximize motivation and retention. A detailed, proposed training program design is presented

  3. Site preparation and excavation for foundation of power plant in construction works for No.2 plant in Tsuruga Nuclear Power Station

    International Nuclear Information System (INIS)

    Japan Atomic Power Co. has completed the improved Calderhall type power station in 1966, BWR type No.1 plant in Tsuruga Power Station in 1970, and the BWR type plant in Tokai No.2 Power Station in 1978. Now, as the fourth nuclear power plant, No.2 plant with 1160 MW output in Tsuruga Power Station is a PWR plant, and a prestressed concrete containment vessel was adopted for the first time in Japan. The site of No.2 plant is the limited area between No.1 plant and the Fugen Power Station, in which only the structures of the power plant can be placed, but there was no space for the temporary structure for construction works and abandoning earth. In excavation, the amount of special explosive was limited to avoid the effect of vibration and flying stones. The geological features of the site were examined by various tests. The outline of the civil engineering works is explained. The area of the site is 71,000 m2, and its level is EL + 7.0m. The amount of excavation is 770,000 m3. The excavation for the foundations of three main buildings amounts to 570,000 m3, and the amount of concrete is 17,500 m3. The method of excavation was selected according to the class of rocks. The excavation works were completed without trouble, and the construction is in progress smoothly. (Kako, I.)

    International Nuclear Information System (INIS)

    A concept for the energy insurance of Ukraine, developed by Arcadis Trischler and Partner is presented. After the investigation of the Ukrainian power sector a new directions for comprehensive restructuring are identified. For practical implementation of the concept the following pilot projects are developed: pilot project for the reconstruction and modernization of 200 MW and 300 MW power plant unit including connected coal mines, a pilot project for the construction of a new heating power plant with an initial capacity of 160 MW /electrical/ at the Bowary site to ensure supplies of the industrial sites there, the construction of a micro-hydropower plant with a capacity of 300 to 400 kW near Nemiroff at the South Bug. The recommended pilot projects are based on the use of the most modern, efficient, and economically successful technologies. The recommended projects for rehabilitation of the 200 MW and 300 MW units are mainly to overcome the crisis in the Ukrainian power sector and to maintain existing thermal power plant units till 2015

  12. Work plan for the remedial investigation/feasibility study-environmental impact statement for the Weldon Spring site, Weldon Spring, Missouri

    International Nuclear Information System (INIS)

    The Weldon Spring Site Remedial Action Project is being conducted as a Major System Acquisition under the Surplus Facilities Management Program (SFMP) of the US Department of Energy (DOE). The major goals of the SFMP are to eliminate potential hazards to the public and the environment that are associated with contamination at SFMP sites and to make surplus real property available for other uses to the extent possible. The Weldon Spring site is located near Weldon Spring, Missouri, about 48 km (30 mi) west of St. Louis. It is surrounded by large tracts of land owned by the federal government and the state of Missouri. The site consists of four raffinate pits, an inactive chemical plant, and a contaminated quarry. The raffinate pits and chemical plant are on adjoining land about 3.2 km (2 mi) southwest of the junction of Missouri (State) Route 94 and US Route 40/61, with access from Route 94. The quarry is located in a comparatively remote area about 6.4 km (4 mi) south-southwest of the raffinate pits and chemical plant area; the quarry can also be accessed from Route 94. These areas are fenced and closed to the public. From 1941 to 1944, the US Department of the Army operated the Weldon Spring Ordnance Works, constructed on the land that is now the Weldon Spring site, for production of trinitrotoluene (TNT) and dinitrotoluene (DNT). The Army used the quarry for disposal of rubble contaminated with TNT. In the mid 1950s, 83 ha (205 acres) of the ordnance works property was transferred to the US Atomic Energy Commission (AEC); this is now the raffinate pits and chemical plant area. An additional 6 ha (15 acres) was later transferred to the AEC for expansion of waste storage capacity. 23 refs., 37 figs., 21 tabs

  14. Collaborative Russian-US work in nuclear material protection, control and accounting at the Institute of Physics and Power Engineering. 3: Emphasis on site-wide issues

    International Nuclear Information System (INIS)

    During 1997, collaborative Russian-US nuclear material protection, control, and accounting (MPC and A) tasks at the Institute of Physics and Power Engineering (IPPE) in Obninsk, Russia are focusing increasingly on site-wide issues, though there is continued work at several major facilities: the Fast Critical Facility, the Technological Laboratory for Fuel Fabrication, and the (new and existing) Central Storage Facility. The collaborative work is being done with US Department of Energy National Laboratories. IPPE's emphasis on site-wide issues has resulted in the formation of a separate division for MPC and A. This new division reports directly to the IPPE Chief Engineer. It is a separate scientific and engineering operating division responsible for coordination and harmonization of MPC and A at IPPE, as well as for audit, assessment and inspection. By virtue of the organizational independence of this new division, IPPE has significantly strengthened the role of MPC and A. Two specific site-wide accomplishments are the consolidation of nuclear material from many buildings to a smaller number, and, as a major part of this strategy, the construction of a nuclear island surrounding the Fast Critical Facility and the new Central Storage Facility. Most of IPPE's weapons-grade nuclear materials will be concentrated within the nuclear island. The paper summarizes the following technical elements: computerized accounting, bar coding, weight measurements, gamma-ray measurements, tamper indicating devices, procedures for physical inventory taking and material balance closure, and video monitoring systems for storage and critical assembly areas

    Full Text Available Web 2.0 allows young people to engage in new kinds of online participation, e.g. on social network sites. When young people produce digital texts to communicate with their friends or connect with them, they engage and integrate their literacy in their everyday lives. Social network sites are thus examples of how digital media open up spaces where literacy becomes part of young people’s social and cultural practices in new and unprecedented ways. Is this development relevant to school-based literacy learning? If so, how should it be met in the classroom? In the paper these questions are addressed against the backdrop of empirical work with Norwegian students and teachers. This material particularly reveals how students and teachers experience the relationship between educational and commercial aspects of young people’s cultural and social lives online. The analyses of the empirical material draw on work contained in New Literacy Studies and Media Education Research. In the discussion section it is argued that the relationship between the educational and commercial aspects of young people’s use of social network sites must be more closely examined in the light of how these activities actually relate to literacy learning in the classroom.

  16. Implications of the Baltimore Rail Tunnel Fire for Full-Scale Testing of Shipping Casks

    2003-02-25

    The U.S. Nuclear Regulatory Commission (NRC) does not currently require full-scale physical testing of shipping casks as part of its certification process. Stakeholders have long urged NRC to require full-scale testing as part of certification. NRC is currently preparing a full-scale casktesting proposal as part of the Package Performance Study (PPS) that grew out of the NRC reexamination of the Modal Study. The State of Nevada and Clark County remain committed to the position that demonstration testing would not be an acceptable substitute for a combination of full-scale testing, scale-model tests, and computer simulation of each new cask design prior to certification. Based on previous analyses of cask testing issues, and on preliminary findings regarding the July 2001 Baltimore rail tunnel fire, the authors recommend that NRC prioritize extra-regulatory thermal testing of a large rail cask and the GA-4 truck cask under the PPS. The specific fire conditions and other aspects of the full-scale extra-regulatory tests recommended for the PPS are yet to be determined. NRC, in consultation with stakeholders, must consider past real-world accidents and computer simulations to establish temperature failure thresholds for cask containment and fuel cladding. The cost of extra-regulatory thermal testing is yet to be determined. The minimum cost for regulatory thermal testing of a legal-weight truck cask would likely be $3.3-3.8 million.

    Supermarket-based interventions are one approach to improving the local food environment and reducing obesity and chronic disease in low-income populations. We implemented a multicomponent intervention that aimed to reduce environmental barriers to healthy food purchasing in a supermarket in Southwest Baltimore. The intervention, Eat Right-Live Well! used: shelf labels and in-store displays promoting healthy foods, sales and promotions on healthy foods, in-store taste tests, increasing healthy food products, community outreach events to promote the intervention, and employee training. We evaluated program implementation through store environment, taste test session, and community event evaluation forms as well as an Employee Impact Questionnaire. The stocking, labeling, and advertising of promoted foods were implemented with high and moderate fidelity. Taste test sessions were implemented with moderate reach and low dose. Community outreach events were implemented with high reach and dose. Supermarket employee training had no significant impact on employees' knowledge, self-efficacy, or behavioral intention for helping customers with healthy purchasing or related topics of nutrition and food safety. In summary, components of this intervention to promote healthy eating were implemented with varying success within a large supermarket. Greater participation from management and employees could improve implementation. PMID:26296352

  18. Legacies of Lead in Charm City’s Soil: Lessons from the Baltimore Ecosystem Study

    2016-01-01

    Understanding the spatial distribution of soil lead has been a focus of the Baltimore Ecosystem Study since its inception in 1997. Through multiple research projects that span spatial scales and use different methodologies, three overarching patterns have been identified: (1) soil lead concentrations often exceed state and federal regulatory limits; (2) the variability of soil lead concentrations is high; and (3) despite multiple sources and the highly heterogeneous and patchy nature of soil lead, discernable patterns do exist. Specifically, housing age, the distance to built structures, and the distance to a major roadway are strong predictors of soil lead concentrations. Understanding what drives the spatial distribution of soil lead can inform the transition of underutilized urban space into gardens and other desirable land uses while protecting human health. A framework for management is proposed that considers three factors: (1) the level of contamination; (2) the desired land use; and (3) the community’s preference in implementing the desired land use. The goal of the framework is to promote dialogue and resultant policy changes that support consistent and clear regulatory guidelines for soil lead, without which urban communities will continue to be subject to the potential for lead exposure.

    Because multi-person syringe use is the most common vehicle for HIV and hepatitis C virus transmission among injection drug users (IDUs), safe sources of sterile syringes and safe methods of disposal are necessary to curb these epidemics. We examined syringe acquisition and disposal in a cohort of IDUs in Baltimore. Between January 1, 1998 and December 31, 2001, 1034 participants reported on syringe acquisition at 3492 visits, and 953 reported on disposal at 2569 visits. Participants were 69.9% male, 93.9% African-American, and median age was 44. Syringes were acquired exclusively from unsafe sources at 32.3% of visits, while exclusively unsafe disposal was reported at 59.3% of visits. Significant correlates of unsafe acquisition were: attending shooting galleries, anonymous sex, sharing needles, smoking crack, and emergency room visits. Significant correlates of unsafe disposal were: injecting speedball, no methadone treatment, acquiring safely, and frequent injection. Having a primary source of medical care was associated with safe acquisition, but unsafe disposal. IDUs continue to acquire safely but dispose unsafely, especially among those with a primary source of care; this suggests that messages about safe disposal are not being disseminated as widely as those about acquisition. These data suggest the need for a more active program involving pharmacists, an expanded syringe access program, and better efforts to enhance safe disposal. PMID:16419554

  2. Disaggregation of collective dose-a worked example based on future discharges from the Sellafield nuclear fuel reprocessing site, UK

    International Nuclear Information System (INIS)

    Collective dose has long been advocated as an important measure of the detriment associated with practices that involve the use of radioactivity. Application of collective dose in the context of worker protection is relatively straightforward, whereas its application in the context of discharges to the environment can yield radically different conclusions depending upon the population groups and integration times that are considered. The computer program PC-CREAM98 has been used to provide an indicative disaggregation into individual dose bands of the collective dose due to potential future radioactive discharges from the nuclear fuel reprocessing site at Sellafield in the UK. Two alternative discharge scenarios are considered, which represent a 'stop reprocessing early, minimum discharge' scenario and a 'reprocessing beyond current contracts' scenario. For aerial discharges, collective dose at individual effective dose rates exceeding 0.015 μSv y-1 is only incurred within the UK, and at effective dose rates exceeding 1.5 μSv y-1 is only incurred within about 20 km of Sellafield. The geographical distribution of collective dose from liquid discharges is harder to assess, but it appears that collective dose incurred outside the UK is at levels of individual effective dose rate below 1.5 μSv y-1, with the majority being incurred at rates of 0.002 μSv y-1 or less. In multi-attribute utility analyses, the view taken on the radiological detriment to be attributed to the two discharge scenarios will depend critically on the weight or monetary value ascribed to collective doses incurred within the differing bands of individual dose rate

  3. Use of DAC-Hours for Radiation Work Permit Suspension Guides and Validation of Respiratory Equipment Selection at the Savannah River Site

    International Nuclear Information System (INIS)

    Historically, the Savannah River Site, like many Department of Energy sites, has used some multiple of the expected Derived Air Concentration (DAC) of a radionuclide as a suspension guide for Radiological Work Permits (RWP) or validation of selected respiratory protection equipment. The term DAC expresses the concentration of a radionuclide in air, typically in mCi/cc. Even though the term DAC is derived from an intake of radioactivity (Annual Limit on Intake) that would result in defined estimated dose to a worker, knowing only the DAC value does not allow a worker's potential dose to be determined. Recently, the Savannah Rive Site has converted to the use of DAC-hours for RWP suspension guides and respiratory equipment validation. The term DAC-hr takes into account not only the concentration of the radionuclide in air (DAC) but also the time the individual was exposed allowing an estimate of a worker's dose to be determined. The conversion to DAC-hrs resulted in four benefits to the radiation protection program without increasing the risk to workers; (1) consistency with the constant air monitor (CAM) alarm setpoint protocol; (2) consistency with Internal Dosimetry terminology; (3) an a priori determination of the potential risk to a worker; and (4) reduced complexity/error in field calculations. This paper outlines the justification for the conversion to DAC-hrs, the protocols used for field and count room calculations, and the implementation process utilized at the Savannah River Site

  4. Understanding brittle deformation at the Olkiluoto site. Literature Supplement 2010: an Update of Posiva Working Report 2006-25

    International Nuclear Information System (INIS)

    Posiva Working Report 2006-25 arose from the belief that geological modelling at Olkiluoto, Finland, where an underground repository for spent nuclear fuel is at present under construction, could be significantly improved by an increased understanding of the phenomena being modelled, in conjunction with the more sophisticated data acquisition and processing methods which are now being introduced. Since the geological model is the necessary basis for the rock engineering and hydrological models, which in turn provide the foundation for identifying suitable rock volumes underground and for demonstrating long-term safety, its scientific basis is of critical importance. As a contribution to improving this scientific basis, the literature on brittle deformation in the Earth's crust was reviewed up to and including year 2005. The result was a compilation of scientific articles, reports and books on some of the key topics of significance for an improved understanding of brittle deformation of hard, crystalline rocks, particularly heterogeneous migmatitic and metamorphic rocks like those that make up the Olkiluoto bedrock. The present report is a supplement to WR 2006-25, covering the 5-year period 2006-2010, with some key earlier references and an Annotated Bibliography. The present report is subdivided into five chapters, listing recent literature on (1) background subjects and basic principles, (2) the fabric of Olkiluoto-type intact rock (gneisses, migmatites, fault rocks), (3) formation and characteristics of brittle deformation features (fracture mechanics, brittle microtectonics), (4) fracture data acquisition and processing (statistical characterisation and modelling of fracture systems), and (5) the characterisation of brittle deformation zones (for deterministic and dynamic modelling), corresponding to the first five chapters of the earlier report

    Inappropriate waste disposal is a serious issue in many urban neighborhoods, exacerbating environmental, rodent, and public health problems. Governments all over the world have been developing interventions to reduce inappropriate waste disposal. A system dynamics model is proposed to quantify the impacts of interventions on residential waste related behavior. In contrast to other models of municipal solid waste management, the structure of our model is based on sociological and economic studies on how incentives and social norms interactively affect waste disposal behavior, and its parameterization is informed by field work. A case study of low-income urban neighborhoods in Baltimore, MD, USA is presented. The simulation results show the effects of individual interventions, and also identify positive interactions among some potential interventions, especially information and incentive-based policies, as well as their limitations. The model can help policy analysts identify the most promising intervention packages, and then field test those few, rather than having to pilot test all combinations. Sensitivity analyses demonstrate large uncertainties about behavioral responses to some interventions, showing where information from survey research and social experiments would improve policy making.

    Among youth 15 to 24 years of age, homicide and nonfatal shootings are the leading causes of mortality and morbidity. Urban youth's attitudes and perceptions about the use of gun violence to resolve conflict present a major barrier to efforts to reduce gun homicides and nonfatal shootings. The current investigation extends the existing literature on attitudes toward guns and shootings among high-risk youth ages 18 to 24 by measuring perceived norms and viewpoints regarding gun violence in two analogous Baltimore City neighborhoods pre-implementation and 1-year post-implementation of the Safe Streets intervention (adapted from the CeaseFire/Cure Violence intervention). The Safe Streets intervention is designed for communities with high rates of gun violence and utilizes outreach workers to identify and build trusting relationships with youth ages 15 to 24 who are at greatest risk of being involved in gun violence. The outreach workers also position themselves in the community so that they can rapidly intervene in disputes that have the potential to lead to gun violence. Chi-squared tests and exploratory structural equation modeling (ESEM) were used to examine changes in attitudes toward gun violence 1 year after the implementation of the Safe Streets intervention. There was a statistically significantly improvement in 43 % of the attitudes assessed in the intervention community post-intervention compared to 13 % of the attitudes in the control community. There was a statistically significant improvement in the violent attitudes toward personal conflict resolution scale after implementation of the intervention in both the intervention (b = -0.522, p violence in the intervention community following the implementation of the Safe Streets program. These findings offer promising insights into future community violence prevention efforts. PMID:27294969

    The North-East Corridor project aims to use a top-down inversion methodology to quantify sources of Greenhouse Gas (GHG) emissions over urban domains such as Washington DC / Baltimore with high spatial and temporal resolution. Atmospheric transport of tracer gases from an emission source to a tower mounted receptor are usually conducted using the Weather Research and Forecasting (WRF) model. For such simulations, WRF employs a parameterized turbulence model and does not resolve the fine scale dynamics generated by the flow around buildings and communities comprising a large city. The NIST Fire Dynamics Simulator (FDS) is a computational fluid dynamics model that utilizes large eddy simulation methods to model flow around buildings at length scales much smaller than is practical with WRF. FDS has the potential to evaluate the impact of complex urban topography on near-field dispersion and mixing difficult to simulate with a mesoscale atmospheric model. Such capabilities may be important in determining urban GHG emissions using atmospheric measurements. A methodology has been developed to run FDS as a sub-grid scale model within a WRF simulation. The coupling is based on nudging the FDS flow field towards that computed by WRF, and is currently limited to one way coupling performed in an off-line mode. Using the coupled WRF / FDS model, NIST will investigate the effects of the urban canopy at horizontal resolutions of 10-20 m in a domain of 12 x 12 km. The coupled WRF-FDS simulations will be used to calculate the dispersion of tracer gases in the North-East Corridor and to evaluate the upwind areas that contribute to tower observations, referred to in the inversion community as influence functions. Results of this study will provide guidance regarding the importance of explicit simulations of urban atmospheric turbulence in obtaining accurate estimates of greenhouse gas emissions and transport.

  13. Seismic anisotropy; a window on how the Earth works: multiple mechanisms and sites, from shallow mantle to inner core

    Osmaston, Miles

    2013-04-01

    Since the seismic anisotropy (SA) in the uppermost oceanic mantle was discovered [1] and attributed to the shearing of olivine by an MOR-divergent flow velocity gradient, rheological mobility interpretations of this type have dominated studies of SA there and elsewhere in the Earth. Here I describe two other SA-generating mechanisms. I will reason that one of these, the anisotropic crystallization from melt, bids fair largely to replace the shearing one and be present in even larger volumes of the Earth, both within its outer 100km and in the Inner Core. The other, the layered deposition of disparate substances, offers to explain the ULVZs and SA in D''. We start with the Upper Mantle. New constraints on its rheological properties and dynamical behaviour have come from two directions. Firstly, contrary to the seismologists' rule-book, the oceanic LVZ is no longer to be thought of as mobile because the presence of interstitial melt strips out the water-weakening of the mineral structure [2, 3]. So we require a substitute for the divergent-flow model for MORs. In fact it also has three other, apparently unrecognized, dynamical inconsistencies. One of these [4] is that there are in the record many rapid changes of spreading rate and direction, and ridge jumps. This cannot happen with a process driven by slow-to-change body forces. Secondly, during the past decade, my work on the global dynamics for the past 150Ma (I will show examples) has shown [4 - 7] that the tectospheres of cratons must extend to very close to the bottom of the upper mantle. And that East Antarctica's 'keel' must actually reach it, because its CW rotation [7] suggests it has been picking up an electromagnetic torque from the CMB via the lower mantle. Xenoliths suggest that the reason for this downwards extent of 'keels' is the same as [3]. To meet these two sets of constraints I will demonstrate my now not-so-new MOR model, which has a narrow, wall-accreting subaxial crack. Among its many features

    Garner, Gregory G.; Thompson, Anne M.

    2013-01-01

    An ensemble statistical post-processor (ESP) is developed for the National Air Quality Forecast Capability (NAQFC) to address the unique challenges of forecasting surface ozone in Baltimore, MD. Air quality and meteorological data were collected from the eight monitors that constitute the Baltimore forecast region. These data were used to build the ESP using a moving-block bootstrap, regression tree models, and extreme-value theory. The ESP was evaluated using a 10-fold cross-validation to avoid evaluation with the same data used in the development process. Results indicate that the ESP is conditionally biased, likely due to slight overfitting while training the regression tree models. When viewed from the perspective of a decision-maker, the ESP provides a wealth of additional information previously not available through the NAQFC alone. The user is provided the freedom to tailor the forecast to the decision at hand by using decision-specific probability thresholds that define a forecast for an ozone exceedance. Taking advantage of the ESP, the user not only receives an increase in value over the NAQFC, but also receives value for An ensemble statistical post-processor (ESP) is developed for the National Air Quality Forecast Capability (NAQFC) to address the unique challenges of forecasting surface ozone in Baltimore, MD.

  16. Feasibility study for remedial action for the groundwater operable units at the chemical plant area and the ordnance works area at the Weldon Spring Site, Weldon Spring, Missouri

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) and the U.S. Department of Army (DA) are conducting an evaluation to identify the appropriate response action to address groundwater contamination at the Weldon Spring Chemical Plant (WSCP) and the Weldon Spring Ordnance Works (WSOW), respectively. The two areas are located in St. Charles County, about 48 km (30 rni) west of St. Louis. The groundwater operable unit (GWOU) at the WSCP is one of four operable units being evaluated by DOE as part of the Weldon Spring Site Remedial Action Project (WSSRAP). The groundwater operable unit at the WSOW is being evaluated by the DA as Operable Unit 2 (OU2); soil and pipeline contamination are being managed under Operable Unit 1 (OU1). Remedial activities at the WSCP and the WSOW are being conducted in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Consistent with DOE policy, National Environmental Policy Act (NEPA) values have been incorporated into the CERCLA process. A remedial investigation/feasibility study (RI/FS) work plan summarizing initial site conditions and providing site hydrogeological and exposure models was published in August of 1995 (DOE 1995). The remedial investigation (RI) and baseline risk assessment (BRA) have also recently been completed. The RI (DOE and DA 1998b) discusses in detail the nature, extent, fate, and transport of groundwater and spring water contamination. The BRA (DOE and DA 1998a) is a combined baseline assessment of potential human health and ecological impacts and provides the estimated potential health risks and ecological impacts associated with groundwater and springwater contamination if no remedial action were taken. This feasibility study (FS) has been prepared to evaluate potential options for addressing groundwater contamination at the WSCP and the WSOW. A brief description of the history and environmental setting of the sites is presented in Section 1.1, key information relative to the

    International Nuclear Information System (INIS)

    The Plutonium Environmental, Safety, and Health (ES and H) Vulnerability Assessment is being conducted by the DOE Office of Environment, Safety, and Health (DOE-EH) to evaluate the ES and H vulnerabilities arising from the Department's storage and handling of its holdings of plutonium and other transuranic isotopes. This report on Savannah River Site (SRS) facilities and materials provides the results of a self-assessment for the purpose of identifying issues as potential vulnerabilities. The report provides data and analyses for the DOE-EH and independent Working Group Assessment Team, which will make the final determination as to ES and H vulnerabilities at SRS. The term ES and H vulnerabilities is defined for the purpose of this assessment to mean conditions that could lead to unnecessary or increased radiation exposure of workers, release of radioactive materials to the environment, or radiation exposure of the public. The self-assessment identifies and prioritizes candidate or potential vulnerabilities and issues for consideration by the Working Group Assessment Team, and will serve as an information base for identifying interim corrective actions and options for the safe management of fissile materials. It will also establish a foundation for decision making regarding the safe management and disposition of DOE plutonium

    International Nuclear Information System (INIS)

    The Lyon-Perrache gas works, built in 1834, presented the whole complexity of an industrial centre which was at the peak of technology. With 12 gas holders, there were as many underground structures, which very probably in were closed as they were when the plant was definitively stopped in 1954. During preliminary explorations on the site, the presence of hydrocarbons was detected in the ground, and the first tar containing vat was brought to light. BRGM and the ''Pollution Service'' Company helped EDF-GDF in this first operational phase. Two types of simultaneous actions were conducted: - Searching for information characterizing the site condition, -Application of actions for the treatment of waste matters in acceptable technical and economical conditions. They were conducted in three distinct steps. The first sept revealed the existence of 7 tanks, which were still susceptible to contain tar and to be at the origin of underground contamination. The second step was marked by the opening of tanks and by the technico-economical analysis of the principal solutions for removing the refuse they contained (rubbish, water, tar). In parallel, the diagnosis about the condition of the sub-soil and of the water table has shown distinct signs of pollution of soil and water by organic compounds (notably hydrocarbons and derivatives). Soil was specially affected at the place of former stockings of incineration residues (bitumen) and straight below the benzol removing unit. The third step, presently in progress, is aiming at a better definition of underground quality around two singular points, in order to define and test the best adapted treatment method. The aims of the future step shall be to reclaim a level of general quality compatible with the future utilization of soil and sub-soil. (author). 4 figs., 5 photos

  19. Use of information and communication technologies to support effective work practice innovation in the health sector: a multi-site study

    2009-11-01

    Full Text Available Abstract Background Widespread adoption of information and communication technologies (ICT is a key strategy to meet the challenges facing health systems internationally of increasing demands, rising costs, limited resources and workforce shortages. Despite the rapid increase in ICT investment, uptake and acceptance has been slow and the benefits fewer than expected. Absent from the research literature has been a multi-site investigation of how ICT can support and drive innovative work practice. This Australian-based project will assess the factors that allow health service organisations to harness ICT, and the extent to which such systems drive the creation of new sustainable models of service delivery which increase capacity and provide rapid, safe, effective, affordable and sustainable health care. Design A multi-method approach will measure current ICT impact on workforce practices and develop and test new models of ICT use which support innovations in work practice. The research will focus on three large-scale commercial ICT systems being adopted in Australia and other countries: computerised ordering systems, ambulatory electronic medical record systems, and emergency medicine information systems. We will measure and analyse each system's role in supporting five key attributes of work practice innovation: changes in professionals' roles and responsibilities; integration of best practice into routine care; safe care practices; team-based care delivery; and active involvement of consumers in care. Discussion A socio-technical approach to the use of ICT will be adopted to examine and interpret the workforce and organisational complexities of the health sector. The project will also focus on ICT as a potentially disruptive innovation that challenges the way in which health care is delivered and consequently leads some health professionals to view it as a threat to traditional roles and responsibilities and a risk to existing models of care

    We examined the influence of age, gender, Black vs. White ethnicity, and education on five indices of personality stability and change across an average interval of 8 years in the East Baltimore Epidemiologic Catchment Area study. In the full sample (n = 505, aged 30-88), examination of structural, rank-order, ipsative, and mean level stability, as well as indices of reliable change suggested that NEO-PI-R personality traits showed moderate to high levels of stability over time. There were few age and gender effects on temporal stability but rank-order, ipsative, and mean level stability were lower among Blacks and individuals with lower education. Future research should explore additional demographic predictors of temporal plasticity in a diverse range of samples, and employ observer ratings to assess personality. PMID:19122849

    We examined age trends in the five factors and 30 facets assessed by the Revised NEO Personality Inventory in Baltimore Longitudinal Study of Aging data (N = 1,944; 5,027 assessments) collected between 1989 and 2004. Consistent with cross-sectional results, Hierarchical Linear Modeling analyses showed gradual personality changes in adulthood: a decline up to age 80 in Neuroticism, stability and then decline in Extraversion, decline in Openness, increase in Agreeableness, and increase up to age 70 in Conscientiousness. Some facets showed different curves from the factor they define. Birth cohort effects were modest, and there were no consistent Gender × Age interactions. Significant non-normative changes were found for all five factors; they were not explained by attrition but might be due to genetic factors, disease, or life experience. PMID:16248708

    Developmental trends in personality traits over 42 years were examined using data from the Baltimore Longitudinal Study on Aging (N = 2,359, aged 17 to 98), collected from 1958 to 2002. Hierarchical Linear Modeling analyses revealed cumulative mean-level changes averaging about 0.5 SD across adulthood. Scales related to Extraversion showed distinct developmental patterns: General Activity declined from age 60 to 90; Restraint increased; Ascendance peaked around age 60; and Sociability declined slightly. Scales related to Neuroticism showed curvilinear declines up to age 70 and then increased. Scales related to Agreeableness and Openness changed little; Masculinity declined linearly. Significant individual variability in change was found. Although intercepts differed, trajectories were similar for men and women. Attrition and death had no effect on slopes. This study highlights the use of lower-order traits in providing a more nuanced picture of developmental change. PMID:16497954

    The US Army Corps of Engineers North Atlantic Division, Baltimore District (CENAB), intends to design and construct a medical and dental research facility for the Walter Reed Army Institute of Research (WRAIR) at the Walter Reed Army Medical Center (WRAMC) at Forest Glen, Maryland. Because almost 100% of the proposed building site is located on an uncontrolled landfill that was thought to possibly contain medical, toxic, radioactive, or hazardous waste, it was assumed that remediation of the site might be necessary prior to or in conjunction with excavation. To assess (1) the need for remediation and (2) the potential hazards to construction workers and the general population, the Baltimore District contracted with Argonne National Laboratory to undertake a site characterization and risk assessment and to develop a foundation-excavation plan. The results of the site characterization and a qualitative risk assessment have been presented in a previous report. This report presents the foundation-excavation plan. 38 refs., 16 figs., 11 tabs.

    This paper presents indoor air pollutant concentrations and allergen levels collected from the homes of 100 Baltimore city asthmatic children participating in an asthma intervention trial. Particulate matter (PM), NO2, and O3 samples were collected over 72 h in the child's sleeping room. Time-resolved PM was also assessed using a portable direct-reading nephelometer. Dust allergen samples were collected from the child's bedroom, the family room, and the kitchen. The mean PM10 concentration, 56.5+/-40.7 microg/m3, is 25% higher than the PM2.5 concentration (N=90), 45.1+/-37.5 microg/m3. PM concentrations measured using a nephelometer are consistent and highly correlated with gravimetric estimates. Smoking households' average PM2.5 and PM10 concentrations are 33-54 microg/m3 greater than those of nonsmoking houses, with each cigarette smoked adding 1.0 microm/m3 to indoor PM2.5 and PM10 concentrations. Large percentages of NO2 and O3 samples, 25% and 75%, respectively, were below the limit of detection. The mean NO2 indoor concentration is 31.6+/-40.2 ppb, while the mean indoor O3 concentration in the ozone season was 3.3+/-7.7 ppb. The levels of allergens are similar to those found in other inner cities. Results presented in this paper indicate that asthmatic children in Baltimore are exposed to elevated allergens and indoor air pollutants. Understanding this combined insult may help to explain the differential asthma burden between inner-city and non-inner-city children. PMID:15820722

    environmental remediation projects tend to be managed under tri-party agreement (DOE, Environmental Protection Agency, and SCDHEC) through the Federal Facilities Agreement. During 25 years of environmental remediation SRS has stabilized and capped seepage basins, and consolidated and capped waste units and burial grounds in the GSA. Groundwater activities include: pump and treat systems in the groundwater, installation of deep subsurface barrier systems to manage groundwater flow, in situ chemical treatments in the groundwater, and captured contaminated groundwater discharges at the surface for management in a forest irrigation system. Over the last 25 years concentrations of contaminants in the aquifers beneath the GSA and in surface water streams in the GSA have dropped significantly. Closure of 65 waste sites and 4 RCRA facilities has been successfully accomplished. Wastes have been successfully isolated in place beneath a variety of caps and cover systems. Environmental clean-up has progressed to the stage where most of the work involves monitoring, optimization, and maintenance of existing remedial systems. Many lessons have been learned in the process. Geotextile covers outperform low permeability clay caps, especially with respect to the amount of repairs required to upkeep the drainage layers as the caps age. Passive, enhanced natural processes to address groundwater contamination are much more cost effective than pump and treat systems.

    International Nuclear Information System (INIS)

    This BIOMASS Theme 2 report has been produced by the Remediation Working Group. The main aim of this group was to test the accuracy of predictions of environmental assessment models that form part of the assessment of the radiological impact of remediation decisions. The other aspects of such decisions, such as the technical feasibility, economic and social factors were beyond the scope of this group. Two scenarios were constructed and applied based on the contamination around the site of a former radium extraction plant in Olen, Belgium, which arose due the discharge of liquid effluents into a local brook; waste disposal practices and the use of waste material as a road surfacing material. This group considered the situation in an area of approximately 100 ha, contaminated as a result of the frequent flooding of a local river and the dredging of bed sediment out of the river onto the riverbanks. The results of a number of environmental surveys in this area were available, giving modelers the opportunity to compare model predictions with actual measurements in the first scenario (known as Type A). The second scenario (Type B) was hypothetical. It was designed to allow modelers to consider the impact of possible future remediation actions, based on input data for a real site. Olen Scenario Type A considered the influence of a past remedial action, particularly the effect of deep ploughing of land subsequently used as pasture for dairy cows. Five modelers submitted results. The effects on radium concentrations in cow's milk during the period 1971-1972 were assessed and compared with post-remediation measurements. Simplified modelling approaches were used to assess the impact of deep ploughing, partly due to the lack of information on the radium heterogeneity in soil as a function of depth, partly because of the lack of information on the technical details of the deep ploughing. The radium concentration in milk was in general overestimated by around one order of

    This study was made to develop information on the hydrogeology and ground-water geochemistry of the Patuxent and Patapsco aquifers (Lower Cretaceous) near Baltimore, Maryland. This information is needed to evaluate the availability and chemical quality of water from these aquifers. The Patuxent aquifer unconformably overlies Lower Paleozoic and Precambrian basement rocks and consists primarily of medium- to coarse-grained quartz sand. Discontinuous lenses of gravel and silty clay are commonly interbedded with the sand-sized material. The Patuxent aquifer in this area attains a thickness of 250 feet and transmissivities range from 2,000 to 8,000 feet squared per day. The Patuxent is the most productive source of ground water in the Baltimore area. In 1982, approximately 11 million gallons of water per day was produced from this unit. Several cones of depression, ranging from 30 to 50 feet below sea level, have developed in response to this pumping stress. The Arundel Formation conformably overlies the Patuxent aquifer. The Arundel is composed predominantly of clay and ranges from 0 to 150 feet thick. The Arundel exhibits very low vertical hydraulic conductivities that are on the order of 10-9 to 10-11 feet per second. This unit acts as the upper confining bed of the Patuxent aquifer in much of the project area. The Patapsco aquifer unconformably overlies the Arundel Formation and is a medium- to fine-grained quartz sand. The Patapsco functions as a water-table aquifer in much of the project area. Although the Patapsco has been heavily pumped in the past, pumpage from that aquifer in Baltimore was negligible in 1982. Brackish-water contamination of the Patuxent and Patapsco aquifers has been a major water-quality problem since the early 1900's. The Patuxent aquifer presently (1982) contains a circular plume of brackish-water contamination about 5 miles in diameter. This plume is centered on the Harbor district and has enlarged measurably since 1945. The Patapsco

  15. Spatial distribution of metals in soils in Baltimore, Maryland: Role of native parent material, proximity to major roads, housing age and screening guidelines

    International Nuclear Information System (INIS)

    We investigated the spatial distribution of heavy metal above-background (anthropic) contents of Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Ti, V, and Zn in Baltimore City surface soils and related these levels to potential contaminating sources. Composite soil samples (0-10 cm depth) were digested using a nitric and hydrochloric extraction technique. Slightly more than 10% of plots exceeded United States Environmental Protection Agency screening guidelines for Pb. In a principal component analysis, the first component corresponded to Co, Cr, and Fe, which are constituents of local mafic rocks. The second component corresponded to Cu, Pb, and Zn which were significantly higher within than beyond a 100 m buffer of the major roads within the city; furthermore, Pb and Zn were higher in older residential lots. - Spatial distribution of metals in soils of an older US city (Baltimore) was affected by parent material, proximity to major roads, and housing age

    2003-09-01

    In a sample of 761 heroin injectors in Baltimore, Maryland, correlates of arrest for drug-related and non-drug-related criminal offenses, by gender, were examined. This investigation examined gender differences in involvement in the drug economy and correlates of arrest. Correlates included roles in the street drug economy, social network attributes, and economic and demographic variables. Gender differences were found. Selling drugs was strongly associated with drug-related arrests for males. Steering (i.e., publicizing drug brands) was highly associated with drug-related arrests for females. Level of heroin addiction was associated with drug-related arrests for males, but not for females. The associations of social network variables with arrests also differed by gender. For females but not males, a higher number of females in one's network was associated with a lower frequency of arrests. For males, having at least one heroin injector in the personal network was associated with a decreased frequency of arrest, while for females the direction of the association was reversed. These findings suggest the importance of modeling drug behaviors by gender. PMID:12930885

    Efforts to create more sustainable cities are evident in the proliferation of sustainability policies in cities worldwide. It has become widely proposed that the success of these urban sustainability initiatives will require city agencies to partner with, and even cede authority to, organizations from other sectors and levels of government. Yet the resulting collaborative networks are often poorly understood, and the study of large whole networks has been a challenge for researchers. We believe that a better understanding of citywide environmental governance networks can inform evaluations of their effectiveness, thus contributing to improved environmental management. Through two citywide surveys in Baltimore and Seattle, we collected data on the attributes of environmental stewardship organizations and their network relationships. We applied missing data treatment approaches and conducted social network and comparative analyses to examine (a) the organizational composition of the network, and (b) how information and knowledge are shared throughout the network. Findings revealed similarities in the number of actors and their distribution across sectors, but considerable variation in the types and locations of environmental stewardship activities, and in the number and distribution of network ties in the networks of each city. We discuss the results and potential implications of network research for urban sustainability governance. PMID:27145945

    International Nuclear Information System (INIS)

    This plan addresses the closure of several aboveground storage tanks in Area 25 of the Nevada Test Site. The unit is currently identified as Corrective Action Unit 126 in the Federal Facility Agreement and Consent Order and is listed as having six Corrective Action Sites. This plan addresses the Streamlined Approach for Environmental Restoration closure for five of the six sites. Four of the CASs are located at the Engine Test Stand complex and one is located in the Central Support Area. The sites consist of aboveground tanks, two of which were used to store diesel fuel and one stored Nalcool (an antifreeze mixture). The remaining tanks were used as part of a water demineralization process and stored either sulfuric acid or sodium hydroxide, and one was used as a charcoal adsorption furnace. Closure will be completed by removal of the associated piping, tank supports and tanks using a front end loader, backhoe, and/or crane. When possible, the tanks will be salvaged as scrap metal. The piping that is not removed will be sealed using a cement grout

    The Hanford Site Self Assessment of Plutonium Environmental Safety and Health (ES and H) Vulnerabilities was conducted in accordance with the US Department of Energy (DOE) Secretary's directive of February 1994. The implementation plans to carry out this directive are contained in the Project Plan and the Assessment Plan. For this assessment, vulnerabilities are defined as conditions or weaknesses that may lead to unnecessary or increased radiation exposure of the workers, release of radioactive materials to the environment, or radiation exposure of the public. The purpose for the Assessment is to evaluate environmental, safety and health vulnerabilities from plutonium operations and storage activities. Acts of sabotage or diversion of plutonium which obviously may have ES and H implications are excluded from this study because separate DOE programs evaluate those issues on a continuing basis. Security and safeguards activities which may have negative impacts on safety are included in the evaluation

    The San Marcos Pueblo, one of the largest and most important cities of the pre-European Southwest, has long been a place of curiosity for archaeologists and geophysicists alike. Despite numerous archaeological investigations, primarily test excavations and surface surveys carried out at San Marcos from the early 1900s to the present, the site retains pottery sherds scattered along the surface from when it was first occupied in the thirteenth century to its abandonment during the Pueblo Revolt of 1680. Geophysical investigations have identified locations of kivas (ceremonial pits), middens (trash heaps), room blocks and possible metallurgy activity in the area. The site is located south of Santa Fe, NM and to the east of the Cerrillos Hills, a source for lead ore and turquoise. The students of SAGE have studied the San Marcos Pueblo for the past 11 years, and produced a map of the northeastern portion of the Pueblo colloquially called 'El Mapa Grande.' Ground penetrating radar (GPR), magnetics, and electromagnetic (EM) data were acquired on 30mx30m grids and seismic refraction data on various profiles throughout El Mapa Grande. During the 2014 field season new GPR data were acquired on two grids, magnetics data on one, and multiple grids were resurveyed with magnetics and EM to enhance resolution. The most recent GPR data extend coverage of two large anomalies that are part of linear EW-trending structures previously identified and consistent with a possible block wall or midden. Low GPR scatter and circular magnetic lows define several kivas. A target area in the NE of El Mapa Grande was thought to be related to metallurgic activity. Analysis of previous seismic data did not resolve any subsurface features corresponding to a metallurgy operation, but detected the magnetically-chaotic Ancha formation. Comparison with magnetic profile data support the interpretation that this anomaly is caused by a sub-crop of the Ancha Formation.

    Full Text Available Abstract Background Organizational features can affect how staff view their quality of work life. Determining staff perceptions about quality of work life is an important consideration for employers interested in improving employee job satisfaction. The purpose of this study was to identify organization specific predictors of job satisfaction within a health care system that consisted of six independent health care organizations. Methods 5,486 full, part and causal time (non-physician staff on active payroll within six organizations (2 community hospitals, 1 community hospital/long-term care facility, 1 long-term care facility, 1 tertiary care/community health centre, and 1 visiting nursing agency located in five communities in Central West Ontario, Canada were asked to complete a 65-item quality of work life survey. The self-administered questionnaires collected staff perceptions of: co-worker and supervisor support; teamwork and communication; job demands and decision authority; organization characteristics; patient/resident care; compensation and benefits; staff training and development; and impressions of the organization. Socio-demographic data were also collected. Results Depending on the organization, between 15 and 30 (of the 40 potential predictor variables were found to be statistically associated with job satisfaction (univariate analyses. Logistic regression analyses identified the best predictors of job satisfaction and these are presented for each of the six organizations and for all organizations combined. Conclusions The findings indicate that job satisfaction is a multidimensional construct and although there appear to be some commonalities across organizations, some predictors of job satisfaction appear to be organization and context specific.

  2. The impacts of aerosol loading, composition, and water uptake on aerosol extinction variability in the Baltimore-Washington, D.C. region

    In order to utilize satellite-based aerosol measurements for the determination of air quality, the relationship between aerosol optical properties (wavelength-dependent, column-integrated extinction measured by satellites) and mass measurements of aerosol loading (PM2.5 used for air quality monitoring) must be understood. This connection varies with many factors including those specific to the aerosol type - such as composition, size, and hygroscopicity - and to the surrounding atmosphere, such as temperature, relative humidity (RH), and altitude, all of which can vary spatially and temporally. During the DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality) project, extensive in situ atmospheric profiling in the Baltimore, MD-Washington, D.C. region was performed during 14 flights in July 2011. Identical flight plans and profile locations throughout the project provide meaningful statistics for determining the variability in and correlations between aerosol loading, composition, optical properties, and meteorological conditions. Measured water-soluble aerosol mass was composed primarily of ammonium sulfate (campaign average of 32 %) and organics (57 %). A distinct difference in composition was observed, with high-loading days having a proportionally larger percentage of sulfate due to transport from the Ohio River Valley. This composition shift caused a change in the aerosol water-uptake potential (hygroscopicity) such that higher relative contributions of inorganics increased the bulk aerosol hygroscopicity. These days also tended to have higher relative humidity, causing an increase in the water content of the aerosol. Conversely, low-aerosol-loading days had lower sulfate and higher black carbon contributions, causing lower single-scattering albedos (SSAs). The average black carbon concentrations were 240 ng m-3 in the lowest 1 km, decreasing to 35 ng m-3 in the free troposphere (above

    Sexual violence and gender-based violence represent a major public health problem causing significant negative mental, physical, and social outcomes for victims. The rapidly growing population of Hispanic women in Baltimore are both more vulnerable to sexual assault and less able to access postassault services. In an effort to assess service utilization and community awareness of the Mercy Medical Center Sexual Assault Forensic Examiners/Forensic Nurse Examiners Program, we conducted a retrospective chart review of 2,322 women who were seen by the program between 2010 and 2013 and found that only 2.5% of the women were identified as Hispanic, about half of what Baltimore City demographic data would predict. This exploratory pilot project, augmented by key informant interviews, reveals that Hispanic women are underutilizing sexual assault services.

    Since 2013, more than 500 seep sites have been located along the continental margin of the eastern US using acoustic signals of gas plumes in the water column. During a July 2015 R/V Atlantis expedition, scientists used the submersible Alvin to explore seep sites at depths of 300 to 1500 m. Study sites ranged from Norfolk Canyon north to New England Seep 2 and included Baltimore, Veatch, and Shallop Canyon sites, as well as new unnamed sites between Norfolk and Baltimore Canyons. Mussels dominated the seep sites (cf ''Bathymodiolus'' childressi) but only small populations (invertebrate species at the newly explored seeps was the red crab, Chaceon sp. and the rock crab, Cancer sp. These crabs are not seep endemic but they were especially abundant at the seeps and were observed to feed and mate on the seep grounds. Molecular tools will be used to explore the genetic structure of mussel populations from Norfolk to New England seeps, and stable isotope methods will be used to test for differences among sites in the source of carbon used by mussels. Alvin video transects and photo-mosaics will be used to collect data on macrofauna associated with seeps and to test the hypothesis that shallow seeps (300-500m) support more diverse assemblages than deep sites (1000-1500m).

    Stuart, Jeffrey Alan

    Part I. A protocol for the routine isolation and purification of purple membrane sheets containing the integral membrane protein, bacteriorhodopsin, was developed based upon modifications of protocols already in the literature. This simplified protocol is geared toward the facile isolation of protein for use in molecular electronic devices. Methods for the incorporation of bacteriorhodopsin into various polymeric supports were also developed, primarily in the form of dried films and hydrated cubes. This work also represents the first reported production of dried films of the deionized protein, or blue membrane. Part II. An architecture for a volumetric optical memory based on the branched-photocycle of bacteriorhodopsin is presented. The branching reaction circumvents problems associated with destructive reading and writing processes and allows access to a stable, long-lived state, separated both temporally and energetically from the main photocycle, thereby making long-term data storage possible. The state, denoted as Q, can only be accessed by exposing the protein to two different wavelengths of light in the proper sequence, with the appropriate temporal separation (roughly 2 ms between the light pulses). The Q-state (assigned as a binary one) is transparent to both writing and reading processes, making them rigorously non-destructive. Bacteriorhodopsin in its resting state is assigned as a binary zero. A differential absorption reading process is used to determine the state of each volumetric binary element. Preliminary results are reported. Part III. The nature of the chromophore binding site of light-adapted bacteriorhodopsin is analyzed by using all-valence electron MNDO and MNDO-PSDCI molecular orbital theory to interpret previously reported linear and nonlinear optical spectroscopic measurements. It is concluded that the unique two-photon properties of the chromophore are due in part to the electrostatic field associated with a Casp{2+} ion near the

    International Nuclear Information System (INIS)

    In Mochovce site the construction of four units of WWER 440 NPP with V-213 type of reactor is being carried out. The financing of Mochovce units completion was resolved in April 1996. The completion work commenced at the construction site under leadership of SKODA Prague, the general supplier. The completion work on building part and tests of constructional electric distributions and lightning constructors started. The revisions in technological part were finished, and final protocols from revisions are the basis for starting of completion work. The assembly of transport container anchorage,ventilation system in hermetic areas and hermetic coverage of pools for stored spent nuclear fuel is being carried out. The pre-completion tests of instrumentation and control of ventilation systems, individual dosimetric control in medical station, and tests of nuclear programme according to commissioning and assembling work schedule at the equipment for physical protection of the NPP area started. Inspection activities at Mochovce were performed in accordance with inspection plan for 1996. Evaluation of routine inspections was performed by means of quarterly protocols. Main findings from the inspections performed in Mochovce were in the following areas: (a) deficiencies in the knowledge of the respective regulation and conditions from the Resolution of the state regulatory body, concerning selected employees; (b) training of the selected employees; (c) aim of the measures imposes by inspectors is to eliminate deficiencies in preparation of programmes for pre-completion and completion testing. NRA SR assessment activities at Mochovce NPP were focused mainly on approving and inspecting of design modification to approving programmes for pre-completion and completion testing of system s and equipment and on approving quality assurance programmes. The suggestions of international missions, which reviewed Mochovce safety in the years, were taken into consideration in the programme

    The Shell 272-1 and 273-1 wells, located c106km SE of Atlantic City, in the NW part of the Baltimore Canyon Trough penetrate strata from Cenozoic down to Upper Jurassic, and the lithology of each is described. 7 major lithologic units were established and correlated to the COST B-2 and B-3 wells. The depositional environments of the Upper Jurassic rocks range from an upper delta plain facies to a back-reef facies. The Lower Cretaceous strata, in a vertical sequence, consist of upper delta plain, lower delta plain, marginal marine, and distributary-mouth-bar deposits. A Cenomanian sandstone is the youngest indicator of deltaic deposition; marine strata dominate the remainder of the Upper Cretaceous and Cenozoic.-from Authors

    The country-of-origin labeling (COOL) law requires United States grocers to indicate the origin and procurement method (farm-raised or wild-caught) for seafood. This study explored the presentation of COOL on fresh, frozen, packaged, and unpackaged seafood in Baltimore City grocery stores. Eight stores were visited bi-monthly to photograph seafood labels, and circulars were collected weekly from fourteen stores over three months. Ninety-six percent of products were labeled correctly. Forty-eight percent of advertisements included COOL. While in-store labels did not highlight COOL, advertising featured references to domestic and wild-caught seafood, signaling to customers that these are high-value product qualities. PMID:24437544

    Health data for free-living eastern box turtles (Terrapene carolina carolina) at the Maryland Zoo in Baltimore were analyzed. One hundred and eighteen turtles were captured on or near zoo grounds over the course of 15 yr (1996-2011), with recapture of many individuals leading to 208 total evaluations. Of the 118 individuals, 61 were male, 50 were female, and 7 were of undetermined sex. Of the 208 captures, 188 were healthy, and 20 were sick or injured. Complete health evaluations were performed on 30 turtles with physical examination records, complete blood counts (CBCs), and plasma biochemistry profiles. Eight animals were sampled more than once, yielding 40 total samples for complete health evaluations of these 30 individuals. The 40 samples were divided into healthy (N=29) and sick (N=11) groups based on clinical findings on physical examination. Samples from healthy animals were further divided into male (N=17) and female (N= 12) groups. CBC and biochemistry profile parameters were compared between sick and healthy groups and between healthy males and females. Sick turtles had lower albumin, globulin, total protein (TP), calcium, phosphorous, sodium, and potassium than healthy animals. Sick turtles also had higher heterophil to lymphocyte ratios. Healthy female turtles had higher leukocyte count, eosinophil count, total solids, TP, globulin, cholesterol, calcium, and phosphorous than healthy males. Banked plasma from all 40 samples was tested for antibodies to Mycoplasma agassizii and Mycoplasma testudineum via enzyme-linked immunosorbent assay. One sample from a clinically healthy female was antibody positive for M. agassizii; none were positive for M. testudineum. This study provides descriptive health data for eastern box turtles and CBC and biochemistry profile information for T. carolina carolina at and near the Maryland Zoo in Baltimore. It also reports low serologic evidence of exposure to mycoplasmosis. PMID:25831575

    The Co-ordinated research programme on the benchmark study for the seismic analysis and testing of WWER-type nuclear power plants was initiated subsequent to the request from representatives of Member States. The conclusions adopted at the Technical Committee Meeting on Seismic Issues related to existing nuclear power plants held in Tokyo in 1991 called for the harmonization of methods and criteria used in Member States in issues related to seismic safety. The Consulltants' Meeting which followed resulted in producing a working document for CRP. It was decided that a benchmark study is the most effective way to achieve the principal objective. Two types of WWER reactors (WWER-440/213 and WWER-1000) were selected as prototypes for the benchmark exercise to be tested on a full scale using explosions and/or vibration generators. The two prototypes are Kozloduy Units 5/6 for WWER-1000 and Paks for WWER-440/213 nuclear power plants. This volume of Working material contains reports on data related to sites and NPPs Paks and Kozloduy

    The present work was done on representative soil samples originating from different former gas-work sites and contaminated with poly-aromatic hydrocarbons (PAH). Because of their genotoxicity these compounds are considered as the major pollutants. A detailed analytical characterization of the polluting organic matter present in these soils shows that the 16 PAH of the US-EPA priority pollutants list (3 to 6 %) are systematically associated to other PAH (7 to 10 %) and to an organic matter extractable with organic solvents (10 to 15%), but also to a non-extractable heavy organic matter (60 to 75 %). The results show that these soils are polluted with PAH-containing coal tars generated by the industrial coal pyrolysis process of gas manufacturing. All the studied soils present a microflora able to degrade all the PAH from the US-EPA list. The main factor limiting the biodegradation rates obtained by biological soil treatment is the lack of accessibility of PAH. This is due to the presence of heavy organic matter of coal tar acting like a trap for the associated PAH. The soils which have not undergone natural attenuation present an important leaching capacity for PAH. This leaching capacity is strongly reduced after even a limited biological treatment. Bacterial tests performed on leachates of biologically treated soils show that they no longer present any detectable acute toxicity or genotoxicity. (author)

  15. Feasibility of determination of low-head hydroelectric power development at existing sites: Brighton Dam hydroelectric development. Feasibility report

    1979-04-01

    The redevelopment of the hydroelectric facility at Brighton Dam near Laurel, Maryland has been found to be both technically and financially feasible, the benefit to cost ratio being 1.53:1 compared with an equivalent coal-based generation source. Environmental impacts have been assessed as relatively slight, but some problems, due to poor water quality at the bottom of the reservoir are anticipated and solutions for these would have to be worked out. The benefit to cost ratio could thus be marginally decreased, but the relative costs of one alternative scheme compared to another would not be affected. There is no apparent impediment to proceeding with the work. The selected development would have a single hydroelectric generating unit of 500 kW rated capacity. The gross generation from the project would be 2,840,000 kWh in the year with average rainfall. It is estimated that the total project cost would be $734,000 (at third quarter 1978 price levels), with no allowance for funds during construction (AFDC). Based on 6.25% cost of money, the project would provide power at a levelized cost over the plant lifetime of approximately 23.3 mills per kWh with no AFDC or 24.6 mills/kWh with AFDC. At present, WSSC electrical power demands at Brighton Dam amount to 147,000 kWh per year which is met by Baltimore Gas and Electric Company (BG and E). This represents only 5% of the potential generation at the site and BG and E have agreed in principal to purchase the surplus power.

  17. Site specific information in site selection

    International Nuclear Information System (INIS)

    The programme for the siting of a deep repository for final disposal of spent nuclear fuel was started already in 1983 and is carried out today by Posiva Oy which continues the work started by Teollisuuden Voima Oy. The programme aims at site selection by the end of the year 2000. The programme has progressed in successive interim stages with defined goals. After an early phase for site identification, five sites were selected in 1987 for preliminary site characterisation. Three of these were selected and judged to be best suited for the more detailed characterisation in 1992. An additional new site was included into the programme based on a separate feasibility study in the beginning of 1997. Since the year 1983 several safety assessments together with technical plans of the facility have been completed. When approaching the site selection the needs for more detailed consideration of the site specific properties in the safety assessment have been increased. The Finnish regulator STUK has published a proposal for general safety requirements for the final disposal of spent nuclear fuel in Finland. This set of requirements has been projected to be used in conjunction of the decision making by the end 2000. Based on the site evaluation all sites can provide a stable environment and there is evidence that the requirements for the longevity of the canister can be fulfilled at each site. In this manner the four candidate sites do not differ too much from each other. The main difference between the sites is in the salinity of the deep groundwater. The significance of differences in the salinity for the long-term safety cannot be defined yet. The differences may contribute to the discussion of the longevity of the bentonite buffer and also to the modelling of the groundwater flow and transport. The use of the geosphere as a transport barrier is basically culminated on the questions about sparse but fast flow routes and 'how bad channeling can be'. To answer these questions

    Full Text Available BACKGROUND: Besides its well-established role in nerve cell survival and adaptive plasticity, brain-derived neurotrophic factor (BDNF is also involved in energy homeostasis and cardiovascular regulation. Although BDNF is present in the systemic circulation, it is unknown whether plasma BDNF correlates with circulating markers of dysregulated metabolism and an adverse cardiovascular profile. METHODOLOGY/PRINCIPAL FINDINGS: To determine whether circulating BDNF correlates with indices of metabolic and cardiovascular health, we measured plasma BDNF levels in 496 middle-age and elderly subjects (mean age approximately 70, in the Baltimore Longitudinal Study of Aging. Linear regression analysis revealed that plasma BDNF is associated with risk factors for cardiovascular disease and metabolic syndrome, regardless of age. In females, BDNF was positively correlated with BMI, fat mass, diastolic blood pressure, total cholesterol, and LDL-cholesterol, and inversely correlated with folate. In males, BDNF was positively correlated with diastolic blood pressure, triglycerides, free thiiodo-thyronine (FT3, and bioavailable testosterone, and inversely correlated with sex-hormone binding globulin, and adiponectin. CONCLUSION/SIGNIFICANCE: Plasma BDNF significantly correlates with multiple risk factors for metabolic syndrome and cardiovascular dysfunction. Whether BDNF contributes to the pathogenesis of these disorders or functions in adaptive responses to cellular stress (as occurs in the brain remains to be determined.

    Substantial evidence supports the value of outdoor education programs for promoting healthy adolescent development, yet measurement of program outcomes often lacks rigor. Accurately assessing the impacts of programs that seek to promote positive youth development is critical for determining whether youth are benefitting as intended, identifying best practices and areas for improvement, and informing decisions about which programs to invest in. We generated brief, customized instruments for measuring three outcomes among youth participants in Baltimore City Outward Bound programs: conflict management, emotional self-efficacy, and problem solving confidence. Measures were validated through exploratory and confirmatory factor analyses of pilot-testing data from two groups of program participants. We describe our process of identifying outcomes for measurement, developing and adapting measurement instruments, and validating these instruments. The finalized measures support evaluations of outdoor education programs serving urban adolescent youth. Such evaluations enhance accountability by determining if youth are benefiting from programs as intended, and strengthen the case for investment in programs with demonstrated success. PMID:27219204

    2013-01-01

    Background While urban redevelopment is intended to ameliorate urban decay, some studies demonstrate that it can negatively impact some residents. Few studies have considered its impact on persons with a history of drug use. Methods A convenience sample of 25 current or former injection drug users from Baltimore, Maryland, enrolled in the AIDS Linked to the Intravenous Experience study, and reporting residence in or bordering a redeveloping neighborhood participated in 1-2 semi-structured in-depth interviews from July, 2011-February, 2012. Interviews explored personal experiences with redevelopment and perceptions of community-wide impact. Data were analyzed using the constant comparison method. Results Respondents rarely described urban redevelopment as solely negative or positive. Revitalization and increased security in the redeveloping area were reported as positive consequences. Negative consequences included the lack of redevelopment-related employment opportunities, disruption of social ties, and housing instability among relocated residents. Respondents also said that urban redevelopment led to the displacement of drug markets to adjacent neighborhoods and outlying counties. Residential relocation and displacement of drug markets were reported as beneficial for persons in contemplative and later stages of recovery. Conclusion These findings support a holistic approach to urban redevelopment that increases access to employment opportunities and affordable housing and ensures equitable coverage of public services such as law enforcement.

    STEP into Action assessed the efficacy of a peer-based HIV prevention intervention in reducing HIV risk behaviors among people who inject drugs (PWIDs) in Baltimore. This analysis examined the effect of the intervention on the change in frequency of conversation about HIV prevention topics over time. 114 participants were randomized into an experimental and 113 into a control group. Data was collected prospectively at 6, 12, and 18 months. The experimental group talked more frequently about HIV prevention topics compared to the control group at 6-month visit. At 18 months relative risk ratios (RRR) remained statistically significant for conversation about the danger of needle sharing (RRR = 3.21) and condom use (RRR = 2.81). The intervention resulted in an increased conversation about HIV prevention among PWIDs, but the sustainability past 6 months remained a challenge; suggesting that interventions should be designed to constantly reinforce communication about HIV prevention among PWIDs.

    We implement a controlled, multi-site experiment to develop and test guidance principles for benefits transfers. These argue that when transferring across relatively similar sites, simple mean value transfers are to be preferred but that when sites are relatively dissimilar then value function...... transfers will yield lower errors. The paper also provides guidance on the appropriate specification of transferable value functions arguing that these should be developed from theoretical rather than ad-hoc statistical approaches. These principles are tested via a common format valuation study of water...... quality improvements across five countries. While this provides an idealised tested, results support the above principles and suggest directions for future transfer studies....

  17. The water-quality monitoring program for the Baltimore reservoir system, 1981-2007—Description, review and evaluation, and framework integration for enhanced monitoring

    The City of Baltimore, Maryland, and parts of five surrounding counties obtain their water from Loch Raven and Liberty Reservoirs. A third reservoir, Prettyboy, is used to resupply Loch Raven Reservoir. Management of the watershed conditions for each reservoir is a shared responsibility by agreement among City, County, and State jurisdictions. The most recent (2005) Baltimore Reservoir Watershed Management Agreement (RWMA) called for continued and improved water-quality monitoring in the reservoirs and selected watershed tributaries. The U.S. Geological Survey (USGS) conducted a retrospective review of the effectiveness of monitoring data obtained and analyzed by the RWMA jurisdictions from 1981 through 2007 to help identify possible improvements in the monitoring program to address RWMA water-quality concerns. Long-term water-quality concerns include eutrophication and sedimentation in the reservoirs, and elevated concentrations of (a) nutrients (nitrogen and phosphorus) being transported from the major tributaries to the reservoirs, (b) iron and manganese released from reservoir bed sediments during periods of deep-water anoxia, (c) mercury in higher trophic order game fish in the reservoirs, and (d) bacteria in selected reservoir watershed tributaries. Emerging concerns include elevated concentrations of sodium, chloride, and disinfection by-products (DBPs) in the drinking water from both supply reservoirs. Climate change and variability also could be emerging concerns, affecting seasonal patterns, annual trends, and drought occurrence, which historically have led to declines in reservoir water quality. Monitoring data increasingly have been used to support the development of water-quality models. The most recent (2006) modeling helped establish an annual sediment Total Maximum Daily Load to Loch Raven Reservoir, and instantaneous and 30-day moving average water-quality endpoints for chlorophyll-a (chl-a) and dissolved oxygen (DO) in Loch Raven and Prettyboy

  18. A New Differential Absorption Lidar to Measure Sub-Hourly Fluctuation of Tropospheric Ozone Profiles in the Baltimore - Washington D.C. Region

    Tropospheric ozone profiles have been retrieved from the new ground based National Aeronautics and Space Administration (NASA) Goddard Space Flight Center TROPospheric OZone DIfferential Absorption Lidar (GSFC TROPOZ DIAL) in Greenbelt, MD (38.99 N, 76.84 W, 57 meters ASL) from 400 m to 12 km AGL. Current atmospheric satellite instruments cannot peer through the optically thick stratospheric ozone layer to remotely sense boundary layer tropospheric ozone. In order to monitor this lower ozone more effectively, the Tropospheric Ozone Lidar Network (TOLNet) has been developed, which currently consists of five stations across the US. The GSFC TROPOZ DIAL is based on the Differential Absorption Lidar (DIAL) technique, which currently detects two wavelengths, 289 and 299 nm. Ozone is absorbed more strongly at 289 nm than at 299 nm. The DIAL technique exploits this difference between the returned backscatter signals to obtain the ozone number density as a function of altitude. The transmitted wavelengths are generated by focusing the output of a quadrupled Nd:YAG laser beam (266 nm) into a pair of Raman cells, filled with high pressure hydrogen and deuterium. Stimulated Raman Scattering (SRS) within the focus generates a significant fraction of the pump energy at the first Stokes shift. With the knowledge of the ozone absorption coefficient at these two wavelengths, the range resolved number density can be derived. An interesting atmospheric case study involving the Stratospheric-Tropospheric Exchange (STE) of ozone is shown to emphasize the regional importance of this instrument as well as assessing the validation and calibration of data. The retrieval yields an uncertainty of 16-19 percent from 0-1.5 km, 10-18 percent from 1.5-3 km, and 11-25 percent from 3 km to 12 km. There are currently surface ozone measurements hourly and ozonesonde launches occasionally, but this system will be the first to make routine tropospheric ozone profile measurements in the Baltimore

  1. Working hot

    International Nuclear Information System (INIS)

    The author says ''barehand'' methods, where specially trained utility workers are called in conductive suits to equalize voltage over their bodies, to maintain high-voltage transmission lines are on the rise. Utilities are building lines at higher voltages and selling more power to other utilities, making it highly inconvenient to take the lines out of service. However, some unions view the barehand work with less than enthusiasm. Touching lines energized at hundreds of thousands of volts demands flawless equipment and rigid work procedures followed to the letter. Some local unions contend that adequate safety procedures and training, and appropriate penalties for workplace negligence, should be in place before utilities may do barehand work. The author discusses some of the methods of barehand work and the equipment used, i.e. steel-mesh lineman's suit, bucket truck's boom, helicopters, and robots

  7. Blended working: for whom it may (not work.

    Directory of Open Access Journals (Sweden)

    Nico W Van Yperen

    Full Text Available Similarly to related developments such as blended learning and blended care, blended working is a pervasive and booming trend in modern societies. Blended working combines on-site and off-site working in an optimal way to improve workers' and organizations' outcomes. In this paper, we examine the degree to which workers feel that the two defining features of blended working (i.e., time-independent working and location-independent working enhance their own functioning in their jobs. Blended working, enabled through the continuing advance and improvement of high-tech ICT software, devices, and infrastructure, may be considered beneficial for workers' perceived effectiveness because it increases their job autonomy. However, because blended working may have downsides as well, it is important to know for whom blended working may (not work. As hypothesized, in a sample of 348 workers (51.7% women, representing a wide range of occupations and organizations, we found that the perceived personal effectiveness of blended working was contingent upon workers' psychological need strength. Specifically, the perceived effectiveness of both time-independent working and location-independent working was positively related to individuals' need for autonomy at work, and negatively related to their need for relatedness and need for structure at work.

    1992-01-31

    The term working memory refers to a brain system that provides temporary storage and manipulation of the information necessary for such complex cognitive tasks as language comprehension, learning, and reasoning. This definition has evolved from the concept of a unitary short-term memory system. Working memory has been found to require the simultaneous storage and processing of information. It can be divided into the following three subcomponents: (i) the central executive, which is assumed to be an attentional-controlling system, is important in skills such as chess playing and is particularly susceptible to the effects of Alzheimer's disease; and two slave systems, namely (ii) the visuospatial sketch pad, which manipulates visual images and (iii) the phonological loop, which stores and rehearses speech-based information and is necessary for the acquisition of both native and second-language vocabulary.

  1. Treatability study on the Bear Creek Valley characterization area at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee. Phase II work plan for S-3 site contaminated groundwater interception--in-field media evaluation and groundwater capture methods

    International Nuclear Information System (INIS)

    A treatability study is being conducted to support implementation:of early actions at the S-3 Site in the Bear Creek Valley (BCV) Characterization Area (CA). The objectives of the early actions Will be (1) to reduce concentrations of uranium and nitrate in Bear Creek and (2) to reduce contaminants of concern in North Tributary (NT)-1 and NT-2. The BCV CA is located within the US DOE's Oak Ridge Reservation in Tennessee. Hazardous and radioactive materials from the Y-12 Plant operations were, disposed of at various sites within BCV. Groundwater and surface water in the BCV CA have been contaminated. The remedial investigation (RI) for the BCV CA identified that the greatest mass flux of contaminants from the various sources migrates via groundwater at the source and discharges to surface water in Bear Creek and its tributaries. In the RI, the combined discharge from the S-3 Site and the Boneyard/Burnyard (BYBY) was identified as accounting for 75% of the cancer risk and more than 80% of the chemical toxicity to Potential downgradient human receptors. In addition, the S-3 Site has caused degradation of surface water quality in upper Bear Creek and two of its tributaries. The BCV CA treatability study focuses on capture and treatment of shallow groundwater before it discharges to tributary waters. The objectives Of treatment of this groundwater are (1) to reduce the concentrations of uranium and nitrate in NT-1 and Bear Creek such that the concentrations of these chemicals in surface water and groundwater are reduced to acceptable levels, (2) to reduce the concentrations of nitrate and metals, and reduce the overall concentration of total dissolved solids; and (3) to hydraulically contain the plume of contaminated, groundwater that is moving in bedrock in the Nolichucky Shale such that the rate of contaminant discharge will be reduced in the long term. The objective of Phase II is to produce conceptual designs for treatment system configurations

    CERN Document Server

    Semblat, Jean-François; Guéguen, Philippe; Bard, Pierre-Yves; Duval, Anne Marie

    2009-01-01

    The analysis of seismic site effects generally disregards the influence of surface structures on the free field motion in densely urbanized areas. This paper aims at investigating this particular problem called site-city interaction especially by comparison to the "free-field" amplification process. Several evidences (experimental, analytical, numerical) of the site-city interaction phenomenon have been given in previous work (Gu\\'eguen, Bard, Semblat 2000). The influence of site city-interaction could be large for structures having eigenfrequencies close to that of the surface soil layers. Furthermore, the density of structures is also an important governing parameter of the problem. Considering a specific site (Nice, France) where site-city interaction is supposed to be significant, we start from detailed experimental and numerical studies of seismic site effects giving both amplification levels and occuring frequencies, as well as the location of the maximum amplification areas. The influence of site-city ...

  16. Testing of environmental transfer models using data from the atmospheric release of Iodine-131 from the Hanford site, USA, in 1963. Report of the Dose Reconstruction Working Group of the Biosphere Modelling and Assessment (BIOMASS) Programme, Theme 2

    International Nuclear Information System (INIS)

    The IAEA Programme on BIOsphere Modelling and ASSessment (BIOMASS) was launched in Vienna in October 1996. The programme was concerned with developing and improving capabilities to predict the transfer of radionuclides in the environment. The programme had three themes: Theme 1: Radioactive Waste Disposal. The objective was to develop the concept of a standard or reference biosphere for application to the assessment of the long term safety of repositories for radioactive waste. Theme 2: Environmental Releases. BIOMASS provided an international forum for activities aimed at increasing the confidence in methods and models for the assessment of radiation exposure related to environmental releases. Two Working Groups addressed issues concerned with the reconstruction of radiation doses received by people from past releases of radionuclides to the environment and the evaluation of the efficacy of remedial measures. Theme 3: Biosphere Processes. The aim of this Theme was to improve capabilities for modelling the transfer of radionuclides in particular parts of the biosphere identified as being of potential radiological significance and where there were gaps in modelling approaches. This topic was explored using a range of methods including reviews of the literature, model inter-comparison exercises and, where possible, model testing against independent sources of data. Three Working Groups were established to examine the modelling of: (1) long term tritium dispersion in the environment; (2) radionuclide uptake by fruits; and (3) radionuclide migration and accumulation in forest ecosystems. This report describes results of the studies undertaken by the Dose Reconstruction Working Group under Theme 2

  18. Dosimetric reevaluation of exposure at working stations of the Mafelec Society. Presence on the production site of elevators push-button containing cobalt 60 between the 21. august and the 7 october 2008

    International Nuclear Information System (INIS)

    On the 7. october 2008, the public authorities were alerted by the Mafelec society of the detection by their customs services of unusual levels of radioactivity during controls on packages containing elevators push-buttons sent by this society. The first measures made on that very day on the site of the Mafelec society at Chimilin (38) by the mobile cell of radiological intervention of Isere department firemen enlightened the presence of radioactivity in elevators the push-buttons in stainless steel and in complete push-buttons delivered to Mafelec by one or several Indian suppliers. After having made an inspection on the site on the 8. october, the nuclear safety authority requested the help of I.R.S.N. to evaluate the doses received by the facility personnel exposed to these radioactive pieces. The Asn also asked I.R.S.N. to evaluate the public exposure if someone used an elevator equipped with such buttons. The first evaluations showed that 22 persons had received a maximal dose between 1.4 and 2.7 mSv. A second report (on the 27 october 2008) gave a revaluation of the dosimetry and went back to the dosimetric evaluation for a person of the public that would take an elevator with push-buttons containing cobalt 60: scenario: presence of a person during 5 minutes by day in the elevator at 50 cm from the control board and that 300 days by year, for this situation the dose received by a person of the public would be about 150 μSv.

  1. Plutonium working group report on environmental, safety and health vulnerabilities associated with the Department's plutonium storage. Volume 2, Appendix B, Part 3: Los Alamos National Laboratory site assessment team report

    International Nuclear Information System (INIS)

    Environmental safety and health (ES and H) vulnerabilities are defined as conditions or weaknesses that may lead to unnecessary or increased radiation exposure of the workers, release of radioactive materials to the environment, or radiation exposure of the public. In response to the initiative by the Secretary of Energy, Los Alamos National Laboratory (LANL) has performed a self assessment of the ES and H vulnerabilities of plutonium inventories at the laboratory. The objective of this site-specific self assessment is to identify and report ES and H vulnerabilities associated with the storage, handling, and processing of plutonium and maintenance of plutonium-contaminated facilities. This self-assessment of ES and H vulnerabilities and validation by a peer group is not another compliance audit or fault-finding exercise. It has a fact finding mission to develop a database of potential environment, safety, and health vulnerabilities that may lead to unnecessary or increased radiation exposure of the workers, release of radioactive materials to the environment, or radiation exposure of the public

    1996-08-01

    This report is a summary of environmental information gathered during a review of the documents pertaining to Project Rulison and interviews with personnel who worked on the project. Project Rulison was part of Operation Plowshare (a program designed to explore peaceful uses for nuclear devices). The project consisted of detonating a 43-kiloton nuclear device on September 10, 1969, in western Colorado to stimulate natural gas production. Following the detonation, a reentry well was drilled and several gas production tests were conducted. The reentry well was shut-in after the last gas production test and was held in standby condition until the general cleanup was undertaken in 1972. A final cleanup was conducted after the emplacement and testing wells were plugged in 1976. However, some surface radiologic contamination resulted from decontamination of the drilling equipment and fallout from the gas flaring during drilling operations. With the exception of the drilling effluent pond, all surface contamination at the Rulison Site was removed during the cleanup operations. All mudpits and other excavations were backfilled, and both upper and lower drilling pads were leveled and dressed. This report provides information regarding known or suspected areas of contamination, previous cleanup activities, analytical results, a review of the regulatory status, the site`s physical environment, and future recommendations for Project Ruhson. Based on this research, several potential areas of contamination have been identified. These include the drilling effluent pond and mudpits used during drilling operations. In addition, contamination could migrate in the gas horizon.

    1992-12-31

    A review has been made of the machines likely to be used in the construction of wind farms. The layout of wind farms of nominal installed capacities ranging from 1MW to 20MW using machines of power output between 150kW and 3200kW at spacings of 10 and 20 times rotor diameter have been considered. Electrical power collection arrangements for machines generating at appropriate voltages have been proposed together with the transmission of the power generated to the bulk transmission system. The civil engineering and building works necessary for farm development have been considered and proposals made for these. A review of likely foundation conditions in the United Kingdom has been made together with proposals for unpiled and piled foundations for the range of machine sizes considered. Costs have been established for the electrical, civil engineering and building works for farms for various nominal installed capacity using machines of different sizes. A method of establishing a budgetary estimate of the site development costs for a wind farm of given capacity using different machine sizes anywhere in the United Kingdom, excluding Northern Ireland, has been put forward. The budgetary estimates so determined should always be confirmed when site specific data is to hand. (author).

    1993-11-01

    A self assessment was conducted of those Hanford facilities that are utilized to store Reactor Irradiated Nuclear Material, (RINM). The objective of the assessment is to identify the Hanford inventories of RINM and the ES & H concerns associated with such storage. The assessment was performed as proscribed by the Project Plan issued by the DOE Spent Fuel Working Group. The Project Plan is the plan of execution intended to complete the Secretary`s request for information relevant to the inventories and vulnerabilities of DOE storage of spent nuclear fuel. The Hanford RINM inventory, the facilities involved and the nature of the fuel stored are summarized. This table succinctly reveals the variety of the Hanford facilities involved, the variety of the types of RINM involved, and the wide range of the quantities of material involved in Hanford`s RINM storage circumstances. ES & H concerns are defined as those circumstances that have the potential, now or in the future, to lead to a criticality event, to a worker radiation exposure event, to an environmental release event, or to public announcements of such circumstances and the sensationalized reporting of the inherent risks.

  13. Site locality identification study: Hanford Site. Volume II. Data cataloging

    Energy Technology Data Exchange (ETDEWEB)

    1980-07-01

    Data compilation and cataloging for the candidate site locality identification study were conducted in order to provide a retrievable data cataloging system for the present siting study and future site evaluation and licensng processes. This task occurred concurrently with and also independently of other tasks of the candidate site locality identification study. Work in this task provided the data utilized primarily in the development and application of screening and ranking processes to identify candidate site localities on the Hanford Site. The overall approach included two steps: (1) data acquisition and screening; and (2) data compilation and cataloging. Data acquisition and screening formed the basis for preliminary review of data sources with respect to their probable utilization in the candidate site locality identification study and review with respect to the level of completeness and detail of the data. The important working assumption was that the data to be used in the study be based on existing and available published and unpublished literature. The data compilation and cataloging provided the basic product of the Task; a retrievable data cataloging system in the form of an annotated reference list and key word index and an index of compiled data. The annotated reference list and key word index are cross referenced and can be used to trace and retrieve the data sources utilized in the candidate site locality identification study.

    2004-04-16

    The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel.

  4. The Hanford Site focus, 1994

    International Nuclear Information System (INIS)

    This report describes what the Hanford Site will look like in the next two years. We offer thumbnail sketches of Hanford Site programs and the needs we are meeting through our efforts. We describe our goals, some recent accomplishments, the work we will do in fiscal year (FY) 1994, the major activities the FY 1995 budget request covers, and the economic picture in the next few years. The Hanford Site budget shows the type of work being planned. US Department of Energy (DOE) sites like the Hanford Site use documents called Activity Data Sheets to meet this need. These are building blocks that are included in the budget. Each Activity Data Sheet is a concise (usually 4 or 5 pages) summary of a piece of work funded by the DOE's Environmental Restoration and Waste Management budget. Each sheet describes a waste management or environmental restoration need over a 5-year period; related regulatory requirements and agreements; and the cost, milestones, and steps proposed to meet the need. The Hanford Site is complex and has a huge budget, and its Activity Data Sheets run to literally thousands of pages. This report summarizes the Activity Data Sheets in a less detailed and much more reader-friendly fashion

  11. Site Remediation in Practice

    International Nuclear Information System (INIS)

    This paper describes the remediation of a former uranium mining area in Hungary. The work was carried out using stringent quality controls and special attention was paid to the radiological survey during the cleanup works on the roads, on pipe lines and yards, on the mill site and places used earlier for heap leaching. Groundwater quality control and the related groundwater quality restoration were the most important aspects of the post remediation phase which was aimed at the long term protection of the nearby drinking water aquifer. The expenditure for the remediation was approximately $100 million. The estimated cost for long term monitoring and water treatment is about US $4 million/year. (author)

  12. Bedrock hydrogeology Forsmark. Site descriptive modelling, SDM-Site Forsmark

    International Nuclear Information System (INIS)

    The Swedish Nuclear Fuel and Waste Management Company (SKB) has conducted site investigations at two different locations, the Forsmark and Laxemar-Simpevarp areas, with the objective of siting a final repository for spent nuclear fuel according to the KBS-3 concept. Site characterisation should provide all data required for an integrated evaluation of the suitability of the investigated site and an important component in the characterisation work is the development of a hydrogeological model. The hydrogeological model is used by repository engineering to design the underground facility and to develop a repository layout adapted to the site. It also provides input to the safety assessment. Another important use of the hydrogeological model is in the environmental impact assessment. This report presents the understanding of the hydrogeological conditions of the bedrock at Forsmark reached following the completion of the surface-based investigations and provides a summary of the bedrock hydrogeological model and the underlying data supporting its development. It constitutes the main reference on bedrock hydrogeology for the site descriptive model concluding the surface-based investigations at Forsmark, SDM-site, and is intended to describe the hydraulic properties and hydrogeological conditions of the bedrock at the site and to give the information essential for demonstrating understanding

    presented in the five subject areas of surface conditions, geology, rock mechanics, hydrogeology and hydrogeochemistry. The aim of the chapter is to provide traceable references to the sources of the data, not to present the data themselves. These data are used for producing the Site Description presented in Chapters 3 to 6 and for making predictions regarding the ONKALO in Chapter 7. Chapters 3 to 6 discuss the current understanding of the site in the five subject areas, with hydrogeology and hydrogeochemistry being presented in an integrated manner in Chapter 6. Each chapter is set out using a similar format, which includes the presentation of the conceptual model, the evaluation of the information, the interaction with other disciplines, the actual modelling and an evaluation of the uncertainties. Chapter 6 also include an evaluation of the results of the integration of hydrogeology and hydrogeochemistry. Based on this description of the site, Chapter 7 presents a first set of predictions concerning the expected geology and rock mechanics properties to be found during the first stage (to 100 m depth) of the excavation of the ONKALO access tunnel and also the hydrogeological and hydrogeochemical impacts of these excavations. Protocols, similar to those developed by SKB, have been applied by the OMTF and are used in a technical auditing exercise as part of the overall modelling work. Chapter 8 reports the conclusions reached after this auditing, however, the audit is restricted to the descriptive modelling of the bedrock geology, rock mechanics, hydrogeology and hydrogeochemistry and does not fully cover the modelling involved in the prediction/outcome studies. Chapter 9 presents the overall achievements of the modelling work and the issues to be considered in future modelling. It is concluded that the format developed for this modelling is suitable and should be used in the future and that the interdisciplinary, integrated working format established by the OMTF should

    the waning stages of the Svecokarelian orogeny. The candidate area is circular-shaped with an area of 54 km2, and hosts the Laxemar subarea in its eastern part. The south-western part of the Laxemar subarea was selected as the focused area for the complete site investigation work, following the initial investigations at the site. Prior to the presentation of the SDM-Site report, three versions of a site descriptive model have been completed for the Laxemar-Simpevarp area and subjected to peer review. The last version, referred to as version Laxemar 1.2, constituted a preliminary site description that concluded the initial site investigation work and was presented in 2006. This preliminary site description formed the basis for a preliminary safety evaluation (PSE) of the Laxemar subarea, a preliminary repository layout, and the first evaluation of the long-term safety of this layout for a KBS-3 repository in the context of the SR-Can project. The final site descriptive model, SDM-Site Laxemar, builds on a coordinated geological model in 3D, into which other discipline-specific models have been integrated without any major conflicting interpretations. In particular, the bedrock thermal and strength properties of the bedrock at the site have been coupled to lithology and identified rock domains in the geological model and an integrated description has been devised that links the hydrogeology and the chemistry of the groundwater to hydraulic conductor domains (deformation zones) and hydraulic rock domains (and underlying fracture domains) and their division in depth zones. These mutually consistent results demonstrate that a fundamental understanding of the current state, properties and processes in Laxemar, from the surface down to potential repository depth, has been achieved. In addition, the properties of the area can be explained in the context of an understanding of its past evolution, throughout a long period of geological history. This integrated understanding of

Prior to the presentation of the SDM-Site report, three versions of a site descriptive model have been completed for the Forsmark area and presented for peer review. The last version, referred to as version 1.2, was a preliminary site description that concluded the initial site investigation work and was presented in 2005. This preliminary site description formed the basis for a preliminary safety evaluation (PSE) of the Forsmark area, a preliminary repository layout (step D1), and the first evaluation of the long-term safety of this layout for KBS-3 repositories in the context of the SR-Can project. The final site descriptive model, SDM-Site, builds on a coordinated geological model in 3D, into which other discipline-specific models have been integrated without any major conflicting interpretations. In particular, the thermal properties of the bedrock at the site have been coupled to identified rock domains in the geological model and an integrated model that links the current stress regime, the hydrogeology and the chemistry of the groundwater to fracture domains and fracture zones in the geological model has evolved. These mutually consistent results demonstrate that a fundamental understanding of the current state of conditions and the on-going processes in the Forsmark area, from the surface down to potential repository depth, has been achieved. In addition, the properties of the area can be explained in the context of an understanding of the past evolution, throughout a long period of geological history. This integrated understanding of the area is presented in chapter 11 of this report and this chapter serves as an executive summary. A systematic assessment of the confidence in the model, including

  20. Reviewing NPP Cernavoda site evaluation

    International Nuclear Information System (INIS)

    The Nuclear Power Plant Cernavoda site was selected before the IAEA Safety Guide issue, during NUSS program development. The Romanian codes issued in 1976, as a regulatory body requirements, establish general criteria regarding safety concept and concentration limits of different radionuclides in air and water body and limits of individual or collective dose. In 1979 the Romanian Authority signed the contract with AECL to improve the CANDU-600 concept in the nuclear development programme and erection of 4 units on the Cernavoda site. The construction work started in 1980. In 1983 the former Romanian Government decided to build up another unit (finally it will be 5 units) on Cernavoda site, so the total gross electrical power we have 3,500 MW. The Canadian safety and quality standards or requirements was harmonized with the Romanian rules and regulations. Many studies, investigations and research were done to qualify the site and have a good knowledge about its characteristics coupled with CANDU-600 performance. The new evolution of the site was performed by Romanian technical staff in CITON and the final conclusions were favourable for erection and operation of NPP. The first unit of Cernavoda NPP is on operation and now the efforts are concentrated to continue the works for the unit 2. The paper underlines how the Cernavoda site characteristics meet IAEA Code of Practice and Safety Guides issued until now. (author)

  1. Status report: Fernald site remediation

    International Nuclear Information System (INIS)

    The Fernald site is rapidly transitioning from a Remedial Investigation/ Feasibility Study (RI/FS) site to one where design and construction of the remedies dominates. Fernald is one of the first sites in the Department of Energy (DOE) complex to accomplish this task and real physical progress is being made in moving the five operable units through the CERCLA process. Two of the required Records of Decision (ROD) are in hand and all five operable units will have received their RODs (IROD for OU3) by the end of 1995. Pre-design investigations, design work or construction are now in progress on the operable units. The lessons learned from the work done to date include implementing innovations in the RI and FS process as well as effective use of Removal Actions to begin the actual site remediation. Also, forging close working relationships with the Federal and State Regulators, citizens action groups and the Fernald Citizens Task Force has helped move the program forward. The Fernald successes have been achieved by close coordination and cooperation among all groups working on the projects and by application of innovative technologies within the decision making process

  6. Making computers work for people

    International Nuclear Information System (INIS)

    In May of 1992, NSP's Prairie Island Nuclear Plant was operating custom-built software on five different site computers to support Work Management, Records Management, Emergency Response, Word Processing, Radiation Protection, and User Applications. A nine-month study was conducted to evaluate the efficiency of the situation and whether improvements were warranted. The study included interviews with users and management for analysis of business needs. A consultant was engaged to assist the study team in defining what the future computer assisted work environment should be. The vision of the future needs resulted in the following strategic objectives: reduce the number of platforms; standardize programmer skills; allow purchase of standard applications; upgrade to state-of-the-art technology; and reduce hardware costs by $750,000 per year. NSP's Prairie Island and Monticello Nuclear Plants have successfully implemented an integrated work management system at both sites. The transition period has been approximately one year from the decision to full implementation. This has been accomplished through the commitment of ALL site employees and outstanding support from Corporate and Vendor organizations

  7. Technology working group

    International Nuclear Information System (INIS)

    The workshop of 26-27 june 2000, on nuclear power Plant LIfe Management (PLIM), also included working groups in which major issues facing PLIM activities for nuclear power plants were identified and discussed. The first group was on Technology. Utilities should consider required provisions capacity by properly maintaining and preserving the existing power plants to the extent practicable and taking into account growing demand, limits of energy conservation, and difficulties in finding new power plant sites. Generally, the extension of the life of nuclear power plant (e.g. from 40 years to 60 years) is an attractive option for utilities, as the marginal cost of most existing nuclear power plants is lower than that of almost all other power sources. It is also an attractive option for environmental protection. Consequently, PLIM has become an important issue in the context of the regulatory reform of the electricity markets. Therefore, the three main objectives of the Technology working group are: 1) Documenting how the safety of nuclear power plants being operated for the long-term has been confirmed, and suggesting ways of sharing this information. 2) Addressing development of advanced maintenance technologies necessary over the plant lifetime, and clarifying their technical challenges. 3) Suggesting potential areas of research and development that might, be necessary. Some potential examples of such research include: - improving the effectiveness of maintenance methods to assure detection of incipient faults; - providing cost effective preventive maintenance programmes; - furnishing systematic, cost-effective refurbishment programmes framed to be consistent with efforts to extend the time between re-fuelling; - developing a methodology that moves routine maintenance on-line without compromising safety.

  11. Work control in separations facilities

    International Nuclear Information System (INIS)

    The topic addressed in this technical review is the development and implementation of a work control program in one of the chemical separations facilities at the Savannah River Site (SRS) in Aiken, SC. This program will be used as a pilot for the Nuclear Materials Processing Division at the site. The SRS Work Control Pilot program is based on the Institute of Nuclear Power Operations (INPO) good practices and guidelines for the conduct of maintenance and complies with SRS quality assurance and DOE orders on maintenance management. The program follows a ten-step process for control of maintenance and maintenance-related activities in a chemical separations facility. The program took the existing maintenance planning and scheduling system and upgraded it to comply with all INPO work control and related guidelines for histories, post-maintenance testing and scheduling. The development process of adapting a nuclear-related- based plan to a batch/continuous chemical separations plant was a challenge. There were many opportunities to develop improvements in performance while being creative and realistic in applying reactor maintenance technology to chemical plant maintenance. This pilot program for work control in a nonreactor nuclear facility will provide valuable information for applying a controlled maintenance process to a multiphase chemical operating plant environment

    This summer I assisted the RPT Program Office in developing a design plan to update their existing website to current NASA web standards. The finished website is intended for the general public, specifically potential customers interested in learning about NASA's chemical rocket test facility capabilities and test assignment process. The goal of the website is to give the public insight about the purpose and function of the RPT Program. Working on this project gave me the opportunity to learn skills necessary for effective project management. The RPT Program Office manages numerous facilities so they are required to travel often to other sites for meetings throughout the year. Maneuvering around the travel schedule of the office and the workload priority of the IT Department proved to be quite the challenge. I overcame the travel schedule of the office by frequently communicating and checking in with my mentor via email and telephone.

This site has been in operation for about forty years and is located approximately seven kilometres south of the Sellafield reprocessing plant in West Cumbria. The site accepts the majority of LLW produced in the U.K. which may be generated by hospitals and general industry as well as the nuclear industry itself. Historically, waste was tumble tipped into trenches which were then covered with an interim cap incorporating a plastic membrane. Waste is now placed in a concrete vault within steel Isofreight containers. This practice will continue through to the end of operations which is anticipated to be in the middle of the next century. Subsequently, a final closure cap will be emplaced over the disposal area. The five year Drigg Site Characterisation programme was, therefore, set up in order to improve and build upon our current understanding of the geology and hydrogeology of the site. The first one and a half years are devoted entirely to data acquisition with the greatest activity surrounding the drilling and geophysical aspects of the programme. Four years will be devoted to collecting a high quality time series data set of water levels, stream flows and meteorological variables and to produce a comprehensive interpretation of the hydrogeology of the site. The programme to date has been very successful and the acquired information has enabled us to start refining our geological model of the site which will then be used to underpin our eventual conceptual hydrogeological model. 3 refs

  6. Chariot, Alaska Site Fact Sheet

    International Nuclear Information System (INIS)

    The Chariot site is located in the Ogotoruk Valley in the Cape Thompson region of northwest Alaska. This region is about 125 miles north of (inside) the Arctic Circle and is bounded on the southwest by the Chukchi Sea. The closest populated areas are the Inupiat villages of Point Hope, 32 miles northwest of the site, and Kivalina, 41 miles to the southeast. The site is accessible from Point Hope by ATV in the summer and by snowmobile in the winter. Project Chariot was part of the Plowshare Program, created in 1957 by the U.S. Atomic Energy Commission (AEC), a predecessor agency of the U.S. Department of Energy (DOE), to study peaceful uses for atomic energy. Project Chariot began in 1958 when a scientific field team chose Cape Thompson as a potential site to excavate a harbor using a series of nuclear explosions. AEC, with assistance from other agencies, conducted more than 40 pretest bioenvironmental studies of the Cape Thompson area between 1959 and 1962; however, the Plowshare Program work at the Project Chariot site was cancelled because of strong public opposition. No nuclear explosions were conducted at the site.

    The Atacama Pathfinder Experiment (APEX) project celebrates the inauguration of its outstanding 12-m telescope, located on the 5100m high Chajnantor plateau in the Atacama Desert (Chile). The APEX telescope, designed to work at sub-millimetre wavelengths, in the 0.2 to 1.5 mm range, passed successfully its Science Verification phase in July, and since then is performing regular science observations. This new front-line facility provides access to the "Cold Universe" with unprecedented sensitivity and image quality. After months of careful efforts to set up the telescope to work at the best possible technical level, those involved in the project are looking with satisfaction at the fruit of their labour: APEX is not only fully operational, it has already provided important scientific results. "The superb sensitivity of our detectors together with the excellence of the site allow fantastic observations that would not be possible with any other telescope in the world," said Karl Menten, Director of the group for Millimeter and Sub-Millimeter Astronomy at the Max-Planck-Institute for Radio Astronomy (MPIfR) and Principal Investigator of the APEX project.

  17. Spent Fuel Working Group Report

    International Nuclear Information System (INIS)

    The Department of Energy is storing large amounts of spent nuclear fuel and other reactor irradiated nuclear materials (herein referred to as RINM). In the past, the Department reprocessed RINM to recover plutonium, tritium, and other isotopes. However, the Department has ceased or is phasing out reprocessing operations. As a consequence, Department facilities designed, constructed, and operated to store RINM for relatively short periods of time now store RINM, pending decisions on the disposition of these materials. The extended use of the facilities, combined with their known degradation and that of their stored materials, has led to uncertainties about safety. To ensure that extended storage is safe (i.e., that protection exists for workers, the public, and the environment), the conditions of these storage facilities had to be assessed. The compelling need for such an assessment led to the Secretary's initiative on spent fuel, which is the subject of this report. This report comprises three volumes: Volume I; Summary Results of the Spent Fuel Working Group Evaluation; Volume II, Working Group Assessment Team Reports and Protocol; Volume III; Operating Contractor Site Team Reports. This volume presents the overall results of the Working Group's Evaluation. The group assessed 66 facilities spread across 11 sites. It identified: (1) facilities that should be considered for priority attention. (2) programmatic issues to be considered in decision making about interim storage plans and (3) specific vulnerabilities for some of these facilities

  19. Site selection: Past and present

    International Nuclear Information System (INIS)

    Site selection has been going on since the earliest times. The process has evolved through the Industrial Revolution to the present period of exploding population and environmental awareness. Now the work must be done both with increasing sophistication and greater transparency. Modern techniques for site selection have been developed during the last two decades or so, utilizing a teachable body of knowledge and a growing literature. Many firms and individuals have contributed to this growing field. The driving force has been the need for such a process in siting and licensing of critical facilities such as nuclear power plants. A list of crucial, documented steps for identifying social impacts and acceptability are provided. A recent innovation is the self-selection method developed by government. The Superconducting Supercollider serves as an example of this approach. Geological or geologically dependent factors often dominate the process. The role as engineering and environmental geoscientists is to provide responsible leadership, consultation, and communication to the effort

    This paper describes the on-going work in the characterization of the Hanford-Site high-level waste tanks. The waste in these tanks was produced as part of the nuclear weapons materials processing mission that occupied the Hanford Site for the first 40 years of its existence. Detailed and defensible characterization of the tank wastes is required to guide retrieval, pretreatment, and disposal technology development, to address waste stability and reactivity concerns, and to satisfy the compliance criteria for the various regulatory agencies overseeing activities at the Hanford Site. The resulting Tank Characterization Reports fulfill these needs, as well as satisfy the tank waste characterization milestones in the Hanford Federal Facility Agreement and Consent Order

    the waning stages of the Svecokarelian orogeny. The candidate area is circular-shaped with an area of 54 km2, and hosts the Laxemar subarea in its eastern part. The south-western part of the Laxemar subarea was selected as the focused area for the complete site investigation work, following the initial investigations at the site. Prior to the presentation of the SDM-Site report, three versions of a site descriptive model have been completed for the Laxemar-Simpevarp area and subjected to peer review. The last version, referred to as version Laxemar 1.2, constituted a preliminary site description that concluded the initial site investigation work and was presented in 2006. This preliminary site description formed the basis for a preliminary safety evaluation (PSE) of the Laxemar subarea, a preliminary repository layout, and the first evaluation of the long-term safety of this layout for a KBS-3 repository in the context of the SR-Can project. The final site descriptive model, SDM-Site Laxemar, builds on a coordinated geological model in 3D, into which other discipline-specific models have been integrated without any major conflicting interpretations. In particular, the bedrock thermal and strength properties of the bedrock at the site have been coupled to lithology and identified rock domains in the geological model and an integrated description has been devised that links the hydrogeology and the chemistry of the groundwater to hydraulic conductor domains (deformation zones) and hydraulic rock domains (and underlying fracture domains) and their division in depth zones. These mutually consistent results demonstrate that a fundamental understanding of the current state, properties and processes in Laxemar, from the surface down to potential repository depth, has been achieved. In addition, the properties of the area can be explained in the context of an understanding of its past evolution, throughout a long period of geological history. This integrated understanding of

    The Middlesex Site discussed in this paper is the Middlesex Sampling Plant (MSP) property, some properties adjacent to the plant, and some vicinity properties. This site has been designated as part of the Formerly Utilized Sites Remedial Action Program (FUSRAP). The steps taken during the decontamination and restoration work are described; there is also discussion of special equipment, new techniques, unexpected problems, and lessons learned which might be applicable to future remedial action tasks. The remedial actions resulted in moving the contaminated materials from the adjacent and vicinity properties to an interim stockpile area. At the stockpile area the material is protected and migration prevented under a controlled monitoring program. Determination of the final disposition of the material has not been made. 33 figures

  11. Repository site characterization - Comparing international experience - 16082

    International Nuclear Information System (INIS)

    An important part of the work described here was a study of existing international experience in investigating deep geological repository sites. The objective of this study was to derive a basis for planning the content and extent of investigations which might be carried out in Germany in the future. Such investigations would be required in the course of a site selection process for a repository for HLW (high level radioactive waste). For this purpose information on suitable sites was gathered, mainly from literature sources. Suitable in this context meant two things. Firstly, the investigated site should be in rock similar to four being considered in Germany (salt, clay, crystalline and other hard rock under a clay cover). Secondly, the investigations carried out could reasonably be considered as being intended to lead to the use of the site as a repository. The investigation processes were presented, analysed and compared. The comparison was based on the quality and the intensity of the methods employed to obtain the information necessary for deciding between candidate repository sites in terms of safety and the feasibility of construction. In the final stage of the work the analysis and presentation method developed for the international sites was applied to the investigations already carried out at three German sites (Gorleben - a prospective HLW repository, Morsleben - an existing but now not operational repository for radioactive waste and Konrad - a repository currently under construction). The reported investigatory work was compared with the ideal investigations developed on the basis of the existing international experience. (authors)

    Many atmospheric and climatic criteria have to be taken into account for the selection of a suitable site for the next generation of imaging air-shower Cherenkov telescopes, the "Cherenkov Telescope Array" CTA. Such data are not available with sufficient precision or the comparability to allow for a comprehensive characterization of the proposed sites to be made. Identical cross-calibrated instruments have been developed which allow for precise comparison between sites, the cross-validation of existing data, and the ground-validation of satellite data.

  14. Recycling abandoned lead battery sites

    International Nuclear Information System (INIS)

    In the past, automobile batteries were recycled principally for their lead content. The waste generated at battery wrecking facilities consisted of spent acid, crushed casings (ebonite and plastic), and where secondary smelting was involved, matte, slag, and carbon from the smelting process. These waste products were generally disposed in an on-site in a landfill or stored in piles. If the facility shut down because further commercial operations were not financially viable, the waste piles remained to be addressed at a later date through remedial action or reclamation programs. There are many of these facilities in the US. Nationally, about 28 sites have been discovered by the US Environmental Protection Agency (EPA) under the Superfund program and are under investigation or administrative orders for remedial action. A major remediation effort is now underway at the Gould Superfund Site in Portland, Oregon, which was operated as a secondary smelting facility between 1949 and 1981. This paper describes the nature of the contamination at the Gould site and the work conducted by Canonie Environmental Services Corp. (Canonie) to develop a process which would treat the waste from battery wrecking operations and produce revenue generating recyclable products while removing the source contamination (lead) from the site. The full-scale commercial plant is now operating and is expected to achieve a throughput rate of between 200 and 250 tons per day in the coming weeks

  18. Site description of Forsmark at completion of the site investigation phase. SDM-Site Forsmark

    Energy Technology Data Exchange (ETDEWEB)

    2008-12-15

    north-western part of the candidate area lacks hydraulically conductive, gently dipping fracture zones at potential repository depth and was selected as the target area for the complete site investigation work, following the initial investigations at the site. Prior to the presentation of the SDM-Site report, three versions of a site descriptive model have been completed for the Forsmark area and presented for peer review. The last version, referred to as version 1.2, was a preliminary site description that concluded the initial site investigation work and was presented in 2005. This preliminary site description formed the basis for a preliminary safety evaluation (PSE) of the Forsmark area, a preliminary repository layout (step D1), and the first evaluation of the long-term safety of this layout for KBS-3 repositories in the context of the SR-Can project. The final site descriptive model, SDM-Site, builds on a coordinated geological model in 3D, into which other discipline-specific models have been integrated without any major conflicting interpretations. In particular, the thermal properties of the bedrock at the site have been coupled to identified rock domains in the geological model and an integrated model that links the current stress regime, the hydrogeology and the chemistry of the groundwater to fracture domains and fracture zones in the geological model has evolved. These mutually consistent results demonstrate that a fundamental understanding of the current state of conditions and the on-going processes in the Forsmark area, from the surface down to potential repository depth, has been achieved. In addition, the properties of the area can be explained in the context of an understanding of the past evolution, throughout a long period of geological history. This integrated understanding of the area is presented in chapter 11 of this report and this chapter serves as an executive summary. A systematic assessment of the confidence in the model, including

    north-western part of the candidate area lacks hydraulically conductive, gently dipping fracture zones at potential repository depth and was selected as the target area for the complete site investigation work, following the initial investigations at the site. Prior to the presentation of the SDM-Site report, three versions of a site descriptive model have been completed for the Forsmark area and presented for peer review. The last version, referred to as version 1.2, was a preliminary site description that concluded the initial site investigation work and was presented in 2005. This preliminary site description formed the basis for a preliminary safety evaluation (PSE) of the Forsmark area, a preliminary repository layout (step D1), and the first evaluation of the long-term safety of this layout for KBS-3 repositories in the context of the SR-Can project. The final site descriptive model, SDM-Site, builds on a coordinated geological model in 3D, into which other discipline-specific models have been integrated without any major conflicting interpretations. In particular, the thermal properties of the bedrock at the site have been coupled to identified rock domains in the geological model and an integrated model that links the current stress regime, the hydrogeology and the chemistry of the groundwater to fracture domains and fracture zones in the geological model has evolved. These mutually consistent results demonstrate that a fundamental understanding of the current state of conditions and the on-going processes in the Forsmark area, from the surface down to potential repository depth, has been achieved. In addition, the properties of the area can be explained in the context of an understanding of the past evolution, throughout a long period of geological history.

  20. Transforming the Duke Power work control process

    International Nuclear Information System (INIS)

    Faced with rising operating and maintenance costs, Duke Power initiated a Work Control Project to provide fundamental rethinking, dramatic quality improvements, and a dramatic reduction in inefficiencies. Other aims were: to do more better with less, to improve coordination between work groups, reduce paperwork, increase effectiveness and utilization of station personnel, and achieve consistent implementation between sites. The existing electronic work management scheme needed some modifications to its software, especially, the programming of a screen to allow simple entry of corrective problems, and the implementation of the new scheduling process. The project has been successful in speeding up the resolution of problems, and in reducing backlogs of maintenance work
