  4. Fluor Hanford ALARA Center is a D and D Resource

    International Nuclear Information System (INIS)

    The mission at the Hanford Nuclear Reservation changed when the last reactor plant was shut down in 1989 and work was started to place all the facilities in a safe condition and begin decontamination, deactivation, decommissioning, and demolition (D and D). These facilities consisted of old shutdown reactor plants, spent fuel pools, processing facilities, and 177 underground tanks containing 53 million gallons of highly radioactive and toxic liquids and sludge. New skills were needed by the workforce to accomplish this mission. By 1995, workers were in the process of getting the facilities in a safe condition and it became obvious improvements were needed in their tools, equipment and work practices. The Hanford ALARA Program looked good on paper, but did little to help contractors that were working in the field. The Radiological Control Director decided that the ALARA program needed to be upgraded and a significant improvement could be made if workers had a place they could visit that had samples of the latest technology and could talk to experienced personnel who have had success doing D and D work. Two senior health physics personnel who had many years experience in doing radiological work were chosen to obtain tools and equipment from vendors and find a location centrally located on the Hanford site. Vendors were asked to loan their latest tools and equipment for display. Most vendors responded and the Hanford ALARA Center of Technology opened on October 1, 1996. Today, the ALARA Center includes a classroom for conducting training and a mockup area with gloveboxes. Two large rooms have a containment tent, several glove bags, samples of fixatives/expandable foam, coating displays, protective clothing, heat stress technology, cutting tools, HEPA filtered vacuums, ventilation units, pumps, hydraulic wrenches, communications equipment, shears, nibblers, shrouded tooling, and several examples of innovative tools developed by the Hanford facilities. See Figures I and

  5. The program of the ALARA Center at Brookhaven National Laboratory

    International Nuclear Information System (INIS)

    In 1984 the Brookhaven National Laboratory was asked by the Nuclear Regulatory Commission to set up a Center to monitor dose-reduction efforts in the US and abroad and to focus the industry's attention on ALARA. The paper summarizes the main work of the ALARA Center between 1984 and 1992. The Center maintains nine data bases for the NRC and the Nuclear Power Industry. These databases are constantly updated and access to them is provided through a personal computer and a modem and by periodic publications in the form of a newsletter and NUREG reports. Also described briefly are eight other projects related to dose-reduction at nuclear power plants that the Center has carried out for the NRC. Among these are projects that analyze the cost-effectiveness of engineering modifications, look at worldwide activities at dose reduction and compare US and foreign dose experience, examine high-dose worker groups and high-dose jobs, develop optimum techniques to control contamination at nuclear plants, and look at the doses being received by men and women in all sectors of the nuclear industry

  6. Fluor hanford ALARA center -showcases- tools, equipment, and work practices used during D and D work

    International Nuclear Information System (INIS)

    In 1996, Fluor established the ALARA Center at the Department of Energy's (DOE) Hanford Site in southeastern Washington State to 'showcase' tools and equipment used to support the principle of As Low As Reasonably Achievable (ALARA). Much of the work was being done by workers who used hand tools while dressed in multiple sets of protective clothing. The Center was opened so that workers could see and handle the latest tools and equipment and have experienced personnel to help them plan work evolutions. Experienced personnel who were familiar with the ALARA concept as well as new technology were assigned to the Center. In addition, vendors were asked to display their products so the Hanford workers could experience state-of-the-art tools and equipment for doing work in a radiological environment. Since opening, the ALARA Center has evolved into a tremendous resource - not only for Hanford, but also most of the entire DOE Complex, as well as contractors around the world. Classes in fundamental radiological work practices are presented when the facilities recognize a need. The ALARA Center has a variety of products that range from simple hand tools to robots, video scopes, and gamma cameras. The tools and equipment on display are used in these training classes to train the workers on the work practices to operate them, take them apart to determine how they work and decide how to maintain them. Many facilities invite the ALARA Center staff to attend planning meetings at the facilities and participate in job walk-downs. Generally, ALARA Center personnel provide several options on how the radiological work can be accomplished safely and recommend the option that is ALARA and safest for the workers. A few years ago, it became obvious that the work scope was changing and many facilities had a new job to clean out the facilities and demolish them. The ALARA Center began contacting vendors who had tools and equipment that could be used for D and D work. Today, the ALARA

  7. BNL ALARA Center experience with an information exchange system on dose control at nuclear power plants

    International Nuclear Information System (INIS)

    The essential elements of an international information exchange system on dose control at nuclear power plants are summarized. Information was collected from literature abstracting services, by attending technical meetings, by circulating data collection forms, and through personal contacts. Data are assembled in various databases and periodically disseminated to several hundred interested participants through a variety of publications and at technical meetings. Immediate on-line access to the data is available to participants with modems, commercially available communications software, and a password that is provided by the Brookhaven National Laboratory (BNL) ALARA Center to authorized users of the system. Since January 1992, rapid access also has been provided to persons with fax machines. Some information is available for ''polling'' the BNL system at any time, and other data can be installed for polling on request. Most information disseminated to data has been through publications; however, new protocols, simplified by the ALARA Center staff, and the convenience of fax machines are likely to make the earlier availability of information through these mechanisms increasingly important

  8. ALARA notes, Number 8

    International Nuclear Information System (INIS)

    This document contains information dealing with the lessons learned from the experience of nuclear plants. In this issue the authors tried to avoid the 'tyranny' of numbers and concentrated on the main lessons learned. Topics include: filtration devices for air pollution abatement, crack repair and inspection, and remote handling equipment

  9. BNL ALARA Center's development of a computerized radiological assessment and design system (RADS)

    International Nuclear Information System (INIS)

    The US Department of Energy's (DOE) Office of Health Physics and Industrial Hygiene sponsored a study of Radiological Engineering Programs at selected DOE contractor facilities. This study was conducted to review, evaluate, and summarize techniques and practices that should be considered in the design phase that reduce dose and the spread of radioactive materials during subsequent construction and operation of DOE radiological facilities. As in a previous study on operational ALARA programs, a variety of good-practice documents will be generated. It is envisioned that these documents will serve as a resource to assist radiological engineers in the process of designing radiological facilities, and in performing radiological safety/ALARA design reviews. This paper presents the features for three good-practice documents and related software applications that are being developed based on the findings of this study. The proposed software called Radiological Assessment and Design System (RADS) will be a menu-driven database and spreadsheet program. It will be designed to provide easy, consistent, and effective implementation of the methodologies described in the three good-practice documents. These documents and the associated RADS software will provide the user with the following three functions: (1) enter dose assessment information and data into computer worksheets and provide printed tables of the results which can then be inserted into safety analysis reports or cost-benefit analyses, (2) perform a wide variety of sorts of radiological design criteria from DOE Orders and produce a checklist of the desired design criteria, and (3) enter cost/benefit data and qualitative rating of attributes for various design alternatives which reduce dose into computer worksheets and provide printed reports of cost-effectiveness results

  10. ALARA: Progress and prospects

    International Nuclear Information System (INIS)

    This paper has two main topics. The first part describes the establishment and work of the ALARA Center; the second part presents some results of studies at the Center with international data on doses at PWR plants. This data then is used to reach a preliminary understanding of some of the factors that are causing high doses at PWRs. This approach should help in reducing occupational exposures in a more effective manner

  11. Alara in industry

    International Nuclear Information System (INIS)

    This paper reviews how the general frameworks of the ALARA procedures, ALARA Audits and Predictive ALARA Plans can be used in the non-nuclear power sector to give practical effect to the concept of optimization. The development of the use of ALARA Audits as an integral part of a Radiation Protection Adviser service and our experience of this structured approach is described. Particular attention is drawn to the use of site specific reference levels to trigger graded levels of response to increasing doses. Also several examples of the use of Cost Benefit Analysis within the ALARA Procedure are briefly described

  12. ALARA development in Mexico

    International Nuclear Information System (INIS)

    Even though the ALARA philosophy was formally implemented in the early 1980's, to some extent, ALARA considerations already had been incorporated into the design of most commercial equipment and facilities based on experience and engineering development. In Mexico, the design of medical and industrial facilities were based on international recommendations containing those considerations. With the construction of Laguna Verde Nuclear Power Station, formal ALARA groups were created to review some parts of its design, and to prepare the ALARA Program and related procedures necessary for its commercial operation. This paper begins with a brief historical description of ALARA development in Mexico, and then goes on to discuss our regulatory frame in Radiation Protection, some aspects of the ALARA Program, efforts in controlling and reducing of sources of radiation, and finally, future perspectives in the ALARA field

  13. Alara and decision analysis

    International Nuclear Information System (INIS)

    In applying ALARA somebody has to determine what is reasonable. A decision has to be made. Decision Analysis is a procedure for structuring decision problems, and therefore it might be expected to be of use in the application of the ALARA principle. This paper explores the contribution that Decision Analysis may make in this context, particularly discussing the application of multi-attribute value theory. An example of using the theory on a problem of radioactive waste disposal is given, and the potential of an increased use of Decision Analysis in making the ALARA principle work, is discussed

  14. What is ALARA

    International Nuclear Information System (INIS)

    The as-low-as-reasonably-achievable (ALARA) philosophy as it applies to personnel radiation exposure has been with us for a long time. The essential tenets of this philosophy surfaced quite early in the history of the Manhattan Project. Although the terminology has suffered through various translations and the application has seen many organizations and agencies come and go, the principles remain as valid today as ever. It is regretable that some regulatory agencies claim ALARA as their newfound miracle drug and that application according to their prescriptions will result in endless rounds of cyclical improvement in radiation protection practices. Others have taken advantage of the popularity of ALARA and have bastardized the philosophy to mean whatever is expedient for their purposes. In this paper, we review briefly the history of ALARA and what it seemingly means to different interest groups and offer a balanced viewpoint that health physicists should adopt

  15. ALARA training at INSTN

    International Nuclear Information System (INIS)

    Since 1990 the CEPN, the National Radiological Protection Board and the INSTN organized for the first time in Europe one teaching specifically established to radioprotection optimization. This training has allowed to spread the experience of the best european specialists while guaranteeing a wide exchange between the participants coming from different countries. At the national level the training ALARA goes on at the INSTN-Saclay. Its aim is to give base notions, the methods and the tools allowing the implementation of the ALARA concept, and to privilege the exchange between the participants coming from different horizons. 2 refs., 2 figs

  16. Applied ALARA techniques

    International Nuclear Information System (INIS)

    The presentation focuses on some of the time-proven and new technologies being used to accomplish radiological work. These techniques can be applied at nuclear facilities to reduce radiation doses and protect the environment. The last reactor plants and processing facilities were shutdown and Hanford was given a new mission to put the facilities in a safe condition, decontaminate, and prepare them for decommissioning. The skills that were necessary to operate these facilities were different than the skills needed today to clean up Hanford. Workers were not familiar with many of the tools, equipment, and materials needed to accomplish:the new mission, which includes clean up of contaminated areas in and around all the facilities, recovery of reactor fuel from spent fuel pools, and the removal of millions of gallons of highly radioactive waste from 177 underground tanks. In addition, this work has to be done with a reduced number of workers and a smaller budget. At Hanford, facilities contain a myriad of radioactive isotopes that are 2048 located inside plant systems, underground tanks, and the soil. As cleanup work at Hanford began, it became obvious early that in order to get workers to apply ALARA and use hew tools and equipment to accomplish the radiological work it was necessary to plan the work in advance and get radiological control and/or ALARA committee personnel involved early in the planning process. Emphasis was placed on applying,ALARA techniques to reduce dose, limit contamination spread and minimize the amount of radioactive waste generated. Progress on the cleanup has,b6en steady and Hanford workers have learned to use different types of engineered controls and ALARA techniques to perform radiological work. The purpose of this presentation is to share the lessons learned on how Hanford is accomplishing radiological work

  17. ALARA engineering at Department of Energy facilities: Bibliography of selected readings in radiation protection and ALARA

    International Nuclear Information System (INIS)

    This report is the second in the series of bibliographies supporting the efforts at the Brookhaven National Laboratory ALARA Center on dose reduction at US Department of Energy (DOE) facilities. The BNL ALARA Center was originally established in 1983 under the sponsorship of the US Nuclear Regulatory Commission to monitor dose-reduction research and ALARA activities at nuclear power plants. This effort was expanded in 1988 by the DOE's Office of Environment, Safety and Health to include DOE nuclear facilities. Abstracts for this bibliography were selected from proceedings of technical meetings, journals, research reports, searches of the DOE Energy Data Base, and reprints of published articles provided by the authors. Information that the reader feels should be included in the next volume of this bibliography may be submitted to the BNL ALARA Center. These abstracts, which have a bearing on dose reduction, consolidates information from publications pertinent to Radiological Engineers and Operational Health Physicists. Volume 2 contains 127 abstracts numbered from 69 through 195 as well as author and subject indices. The subject index contains the abstract numbers from both the previous volume and the current volume, the latter being indicated in boldface

  18. Integration of Formal Job Hazard Analysis and ALARA Work Practice

    CERN Document Server

    Nelsen, D P

    2002-01-01

    ALARA work practices have traditionally centered on reducing radiological exposure and controlling contamination. As such, ALARA policies and procedures are not well suited to a wide range of chemical and human health issues. Assessing relative risk, identifying appropriate engineering/administrative controls and selecting proper Personal Protective Equipment (PPE) for non nuclear work activities extends beyond the limitations of traditional ALARA programs. Forging a comprehensive safety management program in today's (2002) work environment requires a disciplined dialog between health and safety professionals (e.g. safety, engineering, environmental, quality assurance, industrial hygiene, ALARA, etc.) and personnel working in the field. Integrating organizational priorities, maintaining effective pre-planning of work and supporting a team-based approach to safety management represents today's hallmark of safety excellence. Relying on the mandates of any single safety program does not provide industrial hygien...

  2. Gentilly - 2 NGS ALARA program

    International Nuclear Information System (INIS)

    This is a slide-based oral presentation given to the COG/IAEA: Fifth technical committee meeting on 'Exchange of operating experience of pressurized heavy water reactors' held in Mangalia, Romania on 7-10 September 1998. The operation experience of Gentilly -1 and Gentilly - 2 nuclear power stations is summarized. The radiation protection philosophy is addressed, the orange/yellow/green RP qualifications are explained and the ALARA Program objectives are described. The criteria used to develop the Gentilly - 2 station ALARA Program are presented. The program is based on: strong Hydro Quebec commitments, organization (responsibilities well defined); ALARA Committee; tools; procedures; good documentation. Description of the program is given then in details. Measures for dose and radioactive sources reduction are presented. Collective doses recorded at Gentilly - 2 between 1984 and 1997 are plotted and figures are given in a table

  3. Education and training for ALARA

    International Nuclear Information System (INIS)

    The practice of ALARA or the optimisation of Radiation Protection is an important feature of the task of the Radiation Protection Professionals. The teaching of the subject is an equally important part of the education and training curriculum. This paper commences with a general view of the educational process and concludes with specific comments on the educational needs. The concept of ALARA is suggested to be central to the safety culture of radiation protection practice. It is considered to be a part of the scientific culture which is well recognised but not well understood. These topics are reviewed and the conclusions applied to a proposal for a syllabus for the teaching of ALARA and this is compared with the content of courses on the subject. (Author)

  4. Accountability system ALARA/optimization

    International Nuclear Information System (INIS)

    This report makes part of a series of eight reports which have been drawn up in behalf of the dutch Policy Notition Radiation Standards (BNS). The aim of the project with which this report deals, is to assess an accountability system for application of ALARA (As Low As Reasonable Achievable)/optimisation and from these forthcoming bottlenecks. Herein (for this subproject) ALARA is defined as optimization of radiation protection below a risk limit which is to be assessed in another framework. In ch. 2 this discussed further. First it is indicated which categories applications/activities are to be distinguished. Then the elements of the accountability system are elaborated further. In ch. 3 a discussion is given of the actual legislation, the actual policy (national and international), the practice developed with regard to ALARA/optimization and the boundary condition forthcoming from these. In ch. 4 finally the results of ch. 2 are enlightened upon governmental consequences against the background of the actual situation, outlined in ch. 3. In behalf of the insight in the actual practice of ALARA/optimization and the governmental consequences of the in ch. 2 elaborated system interviews have been made with radiation-protection specialists. These are summarized in appendix 2. (H.W.)

  5. Catawba nuclear station preoperational ALARA review

    International Nuclear Information System (INIS)

    This paper describes the particular emphasis placed on preoperational as los as reasonably achievable (ALARA) considerations at Duke Power's Catawba Nuclear Station. A strong station commitment to the ALARA philosophy, and review of existing capabilities, led to development of an aggressive two-part ALARA program. Capabilities consisted of sufficient numbers of available personnel, lengthy lead time during construction, a very detailed plastic model, and a sister plant of similar design. The program, as developed, consisted of a preoperational program, which looked at design and construction aspects of ALARA, and the operational program, dealing with the ALARA committee and operational problems. MAnagement's philosophy of holding everyone responsible for ALARA provided the motivation to organize the preoperational program to use that resource. The Health Physics group accepted responsibility for development, coordination, and reviewer training. The problem provided a base to build on as station personnel gained experience in their own crafts and radiation protection in general

  6. Integration of Formal Job Hazard Analysis and ALARA Work Practice

    International Nuclear Information System (INIS)

    ALARA work practices have traditionally centered on reducing radiological exposure and controlling contamination. As such, ALARA policies and procedures are not well suited to a wide range of chemical and human health issues. Assessing relative risk, identifying appropriate engineering/administrative controls and selecting proper Personal Protective Equipment (PPE) for non nuclear work activities extends beyond the limitations of traditional ALARA programs. Forging a comprehensive safety management program in today's (2002) work environment requires a disciplined dialog between health and safety professionals (e.g. safety, engineering, environmental, quality assurance, industrial hygiene, ALARA, etc.) and personnel working in the field. Integrating organizational priorities, maintaining effective pre-planning of work and supporting a team-based approach to safety management represents today's hallmark of safety excellence. Relying on the mandates of any single safety program does not provide industrial hygiene with the tools necessary to implement an integrated safety program. The establishment of tools and processes capable of sustaining a comprehensive safety program represents a key responsibility of industrial hygiene. Fluor Hanford has built integrated safety management around three programmatic attributes: (1) Integration of radiological, chemical and ergonomic issues under a single program. (2) Continuous improvement in routine communications among work planning/scheduling, job execution and management. (3) Rapid response to changing work conditions, formalized work planning and integrated worker involvement

  7. Integrating ALARA into work planning and organization

    International Nuclear Information System (INIS)

    This paper presents various organizational structures and systematic approaches that can be of benefit in integrating ALARA into work planning and organization. It is possible to have elegant policy statements, procedures and organizations and yet fail to implement ALARA effectively. The real key to success in ALARA work management is to recognize that ALARA is primarily a way of thinking and to secure the commitment of individuals at all levels within the organization, from senior management to workers carrying out specific tasks. The authors explain that the recommendations of ICRP Publication 60 will have an impact and will maintain the downward pressure on individual doses. 6 figs

  8. Chernobyl information: The ALARA backlash

    International Nuclear Information System (INIS)

    The risk information to the public failed after the Chernobyl accident, also in countries where radiation protection authorities and experts initially enjoyed public confidence. In contrast to many other large accidents, the responsibility for the information failure stays mainly with the authorities and experts themselves, not with the mass media. Many factors together caused the radiation risk information from SSI (Swedish Radiation Protection Institute), and its sister authorities in many other countries, to be confusing and inadequate, despite the best of intentions. The two major malefactors were the handling of food contamination restrictions and the short-sighted risk optimisation by applying the ALARA principle. In addition, the assurance that the Chernobyl contamination was fairly harmless made no sense to the layman, as a massive array of controlling procedures was enforced simultaneously. The food regulations became unfortunately focused on becquerel per kilogram limits instead of the primary goal, a dose reduction per year, corresponding to an yearly intake of Cs-137. The lesson learned is that the risk significant long-term intake ambition must be understood and digested by laymen and media, before any secondary limits, e.g. the activity concentration of foodstuffs expressed as becquerel per kg, for controlling or trading purposes, are introduced. As it were, the experts and authorities lost credibility, due to what people considered as ambiguities. The concept of ALARA (As Low As Readily Achievable) is in the backbone of every ionising radiation expert, and a useful strategy for optimising dose burdens during controlled situations. In connection to the Chernobyl accident many advices to the public was given based on the ALARA principle. 'Rinse leafy vegetables' sounds at first very reasonable, cheap and innocent, but if the averted dose is low, such an advice should not be given. The individual dose-reduction should be weighted against all negative

  9. ALARA and planning of interventions

    International Nuclear Information System (INIS)

    The implementation of ALARA programs implies integration of radiation protection criterion at all stages of outage management. Within the framework of its ALARA policy, Electricide de France (EDF) has given an incentive to all of its nuclear power plants to develop open-quotes good practicesclose quotes in this domain, and to exchange their experience by the way of a national feed back file. Among the developments in the field of outage organization, some plants have focused on the planning stage of activities because of its influence on the radiological conditions of interventions and on the good succession of tasks within the radiological controlled areas. This paper presents the experience of Chinon nuclear power plant. At Chinon, we are pursuing this goal through careful outage planning. We want the ALARA program during outages to be part of the overall maintenance task planning. This planning includes the provision of the availability of every safety-related component, and of the variations of water levels in hthereactor and steam generators to take advantage of the shield created by the water. We have developed a computerized data base with the exact position of all the components in the reactor building in order to avoid unnecessary interactions between different tasks performed in the same room. A common language between Operation and Maintenance had been established over the past years, using open-quotes Milestones and Corridorsclose quotes. A real time dose rate counting system enables the Radiation Protection (RP) Department to do an accurate and efficient follow up during the outage for all the open-quotes ALARAclose quotes maintenance tasks

  10. Savannah River Site ALARA Program appraisals

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, J.R.

    1992-06-01

    ALARA Program audits are recommended in PNL-6566, ``Health Physics Manual of Good Practices for Reducing Radiation Exposure to Levels that are As Low As Reasonably Achievable (ALARA).`` The Department of Energy (DOE) Order 5480.11, ``Radiation Protection For Occupational Workers,`` requires contractors to conduct internal audits of all functional elements of the radiological protection program, which includes the ALARA program, as often as necessary, but at a minimum every three years. At the Savannah River Site (SRS), these required audits are performed as part of the Health Protection Internal Appraisal Program. This program was established to review the Site radiological protection program, which includes the ALARA program, on an ongoing basis and to provide recommendations for improvement directly to senior Health Protection management. This paper provides an overview of the SRS Health Protection Internal Appraisal program. In addition, examples of specific performance criteria and detailed appraisal guidelines used ALARA appraisals are provided.

  11. Preliminary ALARA design concept for SMART

    International Nuclear Information System (INIS)

    SMART(System-integrated Modular Advanced ReacTor) is a space saving integral type nuclear rector with the thermal power of 330 MW. This report provides general design guide and authority in NSSS designs for SMART needed to maintain the occupational doses and doses to members of public ALARA to meet the regulatory requirements. Paragraph 20.1 of 10 CFR 20, ''Standards for Protection Against Radiation'', states that licensee should make every reasonable effort to maintain exposures to radiation as far below the limits specified in Part 20 as is reasonably achievable. The ALARA (as low as is reasonably achievable) principle is incorporated into Korean radiation protection law as paragraph one Article 97 of the Atomic Energy Act. (Jan. 1995). This ALARA Design Concept for SMART provides 1) description of the organization and responsibilities needed for upper level management support and authority in order for the implementation of ALARA, 2) guidance and procedures for design, review, and evaluation needed for SMART ALARA program implementation, 3) general design guidelines for SMART NSSS and BOP designers to implement ALARA principles in design stage, and 4) training and instruction requirement of SMART NSSS and BOP designers for the familiarization of ALARA principles to be implemented in NSSS designs.

  12. Alara - from theory towards practice

    International Nuclear Information System (INIS)

    The Alara principle states that all exposures shall be kept as low as reasonably achievable, economic and social factors being taken into account. It is a simple concept - the idea behind it is widely used in nearly all spheres of life, i.e. to do the best one can under the given circumstances. This book aims to help define what is meant by best in the context of radiation protection. It describes a procedure that is useful in structuring one's approach to any particular situation where a decision as to the best course of action is required. It also provides practical guidance on how the concept can be incorporated into radiation protection programmes. This book has been written as a reference manual on both the theoretical and practical aspects of the subject. But it is especially targeted at those involved in radiation protection at the practical level

  13. Can practical ALARA be taught?

    International Nuclear Information System (INIS)

    Full text: Purpose: Outside of the nuclear industry, many users of sources of ionising radiation may be characterised as 'High Frequency/Low Dose' users. It is argued here that they have special training requirements in order to understand the ICRP concept ALARA, indeed all the fundamental concepts of radiological protection and their relevance to the workplace. It is not practicable to practise dose avoidance in many situations so dose reduction becomes even more important. For example, laboratory life sciences researchers often have to use very small quantities and activities of beta emitting radioisotopes which give small or minuscule external doses to well trained workers but can give extremely serious high doses if mishandled Similarly, dentists routinely use 60- 100 kV X-ray generators to diagnose abnormalities and disease which other techniques would fail to detect. By practising simple and effective dose reduction methods, they can reduce the dose to themselves and their patients to arguably trivial levels. Method: The paper will use examples from Radiation Protection Supervisors courses run over the past 6 years for UK pharmaceutical companies and research into courses for general dental practitioners run over the past 8 years in East Anglia, England. The latter courses must meet the requirements laid down in the Ionising Radiation (Medical Exposure) Regulations 2000 and the requirements of the professional dental association, the British Dental Council, and the continuing professional development requirements of the dental registration body, the General Dental Council. Major Findings and Conclusions: The research findings show an urgent need to train dental practitioners in the concepts and practical aspects of dose avoidance and dose minimisation, social and economic factors being considered.

  14. World class ALARA performance at Darlington Nuclear

    International Nuclear Information System (INIS)

    In January 2008, Darlington Nuclear was selected by Information System on Occupational Exposure (ISOE) North American Technical Center to receive the 2007 World Class ALARA Performance Award for setting and achieving high standards in radiation protection. The purpose of this presentation is to share some of the station's successes and challenges in reducing dose to operation and maintenance personnel. In particular, the following dose reduction initiatives will be discussed: - Innovative shielding design including the use of water shielding walls for on-line airlock maintenance, tungsten shielding blocks for feeder replacement, and exposure reduction for horizontal flux detectors - Use of remote monitoring array to scan reactor face for hot spots to reduce dose and save critical path time - Tritium reduction through improvements in human performance, outage scheduling and introduction of new technology With increasing work scope associated with maintenance, refurbishment and retro-fit activities, there is an upward pressure on collective dose making it a critical resource for many inspection and maintenance work groups. There is a need to reduce radiation source terms as a lasting solution to address ever-increasing collective dose. Darlington's long term strategic goals to reduce tritium and gamma source terms and a bold vision for the future will be discussed. (author)

    This note provides a theoretical justification of optimal foldover plans in terms of uniformity.A new lower bound of the centered L2-discrepancy values of combined designs is obtained,which can be used as a benchmark for searching optimal foldover plans.Our numerical results show that this lower bound is sharper than existing results when more factors reverse the signs in the initial design.

  16. Maintaining occupational dose ALARA through work management

    International Nuclear Information System (INIS)

    Canadian philosophy in keeping occupational dose ALARA has been to train staff in radiation safety so that they can be fully responsible for participating in minimizing the risks associated with the hazardous work. Senior managers actively promote high standards of performance in dose reduction techniques as a means for integrating ALARA into the operation and maintenance of the station by all personnel. Minimizing radiation dose is accomplished by applying cost effective work management techniques such as Job Safety Analysis, pre-job briefings and establishing and achieving radiation dose goals. Radiation dose goals are used as a management tool for involving all work groups in reducing doses as well as providing a means of assessing the effectiveness of dose reduction actions. ALARA, along with conventional safety, is used as a lever to raise the standard of quality of work and to overall build a safety culture. (author). 4 figs

  18. New influences on the ALARA concept

    International Nuclear Information System (INIS)

    The ALARA concept is an essential component of an occupational radiation protection program because the fatality risk associated with continued exposure at or near the 5-rems/year limit is unacceptably high. Using a risk coefficient of 4 x 10-4 fatalities/person-rem the risk for a large worker population exposed in this manner for a working lifetime would be 10%. The ICRP fatality risk criterion is an average of 1 per year per 10 thousand workers. The average annual dose that would achieve this objective depends on the risk coefficient used. Using 4 x 10-4 again, the annual dose average would have to be 0.25 rem, a factor of 20 below the limit. It is evident that the ALARA concept is the most important aspect of occupational radiation protection and that the justification for an effective ALARA program is the cancer fatality risk. Not quite so evident but nonetheless important is the consideration that once the ICRP criterion is achieved, it is probably int eh best interest of the workforce to use resources available for their health and safety to reduce other risks. In this paper the risk information under examination by the government agencies is reviewed from the viewpoint of dose reduction through enhanced implementation of the occupational ALARA concept

  19. Radiation exposure management - The Westinghouse ALARA program

    International Nuclear Information System (INIS)

    Westinghouse has incorporated radiation management into the design of its NSSS plants. This paper describes the Westinghouse program for incorporating As Low As Reasonably Achievable (ALARA) radiation exposure into the design process. A description is given of the method of collecting data from operating Westinghouse plants. The analysis of this data and its use in the total NSSS plant exposure estimate is presented. Application of a detailed exposure review to the development of an improved mechanical component is described. A particular exposure review for a refueling task is discussed. One high exposure task is detailed and specific design improvements are identified. The disadvantages of the existing design are expressed and design improvements are suggested. The matrix management of the team that develops the improved design is described and the resulting product is presented. The specific example is used to illustrate the operation of the Westinghouse ALARA program

  20. ALARA in the radiation protection training

    International Nuclear Information System (INIS)

    This part treats especially the question of the training in radiation protection. The electro nuclear sector has given an ALARA principle culture and succeeded to sensitize each level of hierarchy, but for small industry, the research and the medical world the same method appears more difficult to use. It seems better to reinforce the importance of the competent person and to include a training in radiation protection on the initial formation in numerous professional categories. (N.C.)

  1. ALARA application in Spanish NPP's. New approach

    International Nuclear Information System (INIS)

    One main objective of all nuclear installations is to underlie the principle of optimization. The focus in the application of this principle varies considerably, from cost-benefit techniques in the design phases to commitment, attitude and motivation in operation. The ALARA principle should permeate the entire organisation of the company during operation. Management should be the first link of a chain originating with explicit corporate commitment, leading to increasingly specific decisions, finally to reach those who are responsible for actual performance of each task. The safety culture is an element integrating the mentality that is to prevail throughout the organisation. The organisation shall contribute to incorporating the principle of optimization in all plant operations and all phases of activity. Management's commitment and motivation are transferred to all the workers and organisations involved. The ALARA commitment naturally extends to all outside organisations. The ultimate objective is to reduce collective doses through the promotion and enforcing of an ALARA culture and compliance with the operating collective dose objectives. (author)

  2. ALARA Review of the SHAARS Operation

    International Nuclear Information System (INIS)

    The SHARS mobile hot cell was designed and manufactured by Necsa intended to address the problem of disused Spent High Activity Radioactive Sources (SHARS) from teletherapy units, gamma irradiators and brachytherapy units. This unit is to be used in countries with no remote infrastructure to handle SHARS. The hot cell was designed for a 3.7E+13Bq (1000Ci) activity although it was demonstrated that it can handle even more than 7.4E+13Bq (2000Ci). The unit has a biological shield which consists of river sand sandwiched between metal plates and a viewing window filled with 50% zinc bromide solution. The unit was designed to provide sufficient shielding to ensure that doses are kept ALARA (As low As Reasonably Achieved). This paper compares the modelled dose rates with the actual measured doses during operations conducted in Sudan, Tanzania and Uruguay. It also presents the key lessons learned in the application of the ALARA principle during the SHARS missions. The new working practices and additional methods are proposed in order to reduce doses in accordance with the ALARA principle. (author)

  3. The Alara principle in backfitting Borssele

    International Nuclear Information System (INIS)

    An extensive backfitting program, the Modifications Project, was carried out at the Borssele Nuclear Power Station. It involved sixteen modifications to technical systems. The scope of activities, and the dose rates encountered in places where work was to be performed, made it obvious from the outset that a high collective dose had to be anticipated. As a consequence, radiation protection within the project was organized in such a way that applicable radiation protection principles were applied in all phases of the project. From the point of view of radiation protection, the Modifications Project had to be subdivided into three phases, i.e., a conceptual design phase in which mainly the justification principle was applied; the engineering phase in which the Alara principle was employed; the execution phase in which management of the (internal) dose limits had to be observed in addition to the Alara principle. Throughout all project phases, radiation protection considerations and results were documented in so-called Alara reports and radiation protection checklists. As a result of the strictest possible observance of radiation protection principles in all phases of the project, a collective dose of 2505 mSv was achieved, which stands for a reduction by a factor of 4 compared to the very first estimate. In view of the scope and complex nature of the activities involved, and the radiation levels in the Borssele Nuclear Power Station, this is an excellent result. (orig.)

  10. ALARA at Tyco Health care-Mallinckrodt

    International Nuclear Information System (INIS)

    How to approach the ALARA requirement? That was one of the question in the beginning of the 1990's at the Mallinckrodt site for the preparation of radiopharmaceuticals. This question was raised after the ICRP published their guidelines in the ICRP 60 publication, with the average effective dose limit that was changed from 50 to 20 mSv per year. In the early 1990's the individual effective dose at Mallinckrodt was up to 20 mSv7year and some of the people over this number. As a first result of the discussion Mallinckrodt adopted the 20 mSv/year as being the legal limit, although it finally took over a decade to incorporate this ICRP limit into legislation. A second action was to introduce a site internal limit: if a person would exceed 75% of the legal limit, the person would be restrained from radiation work. This restriction forced everybody to look for solutions to decrease dose and area dose rate. This was the beginning and resulted in nobody exceeding 15 mSv/year after a couple of years and a lower average dose than before, with no extra employees. The second stage in the process of ALARA was a systematic approach of the decrease in personal dose. This systematic approach consists of three phases. The first phase is dose assessment followed by routine measurements. The third phase is the ALARA step. First phase, dose assessment. Normally this could be done in a meeting or even behind the desk: assess the dose per department or per group or per activity. Make a decision on which party will get high priority, medium priority and low priority. Normally this means that the department with the highest dose will get the highest priority. (Author)

  11. Maintenance and radioprotection: the implementation of ALARA

    International Nuclear Information System (INIS)

    The increasing maintenance works on reactors has incited Electricite de France (EDF) to adopt a dosimetry optimization policy using the ALARA (As Low As Reasonably Achievable) principle. Reactor maintenance represents 80% of the personnel exposures. This paper described the actions taken by EDF to improve the personnel (EDF and contractors) training and surveillance (medical examination, film dosemeters..) and the labor laws relative to the contractors and temporary employees. Other tools developed by EDF, such as robots, remote handling equipments, and a computerized individual and collective dosimetry database are described. (J.S.). 2 figs

  12. Strengthening ALARA approach in work management at Krsko NPP

    International Nuclear Information System (INIS)

    As Low As Reasonably Achievable (ALARA) occupational exposures at nuclear power plants should be included in work management as a concept. There are world-wide trends required by the utilities for improved design, operation and maintenance. Within the period of seventeen years of plant operation maintaining low radiation exposures requires additional efforts. The benefit of this effort should be reducing risks to nuclear workers, better work planning and performance. The Krsko Plant ALARA organisations has been revised recently and built on different levels of the hierarchy. The goal is to promote good industry practice and the management of work on primary systems. The established ALARA programme describes the objectives and defines the procedures and tools for its implementation. Brief presentation of the programme as well as organisational responsibilities of dedicated ALARA committee and working groups is the scope of this paper. The management tools and ALARA indicators are discussed to implement the programme and to evaluate the results.(author)

    The United States Nuclear Regulatory Commission contracted with Pacific Northwest Laboratory (PNL) to provide technical assistance in establishing operational guidelines, with respect to radiation control programs and methods of minimizing occupational radiation exposure, at Low-Level Waste (LLW) disposal sites. The PNL, through site visits, evaluated operations at LLW disposal sites to determine the adequacy of current practices in maintaining occupational exposures as low as is reasonably achievable (ALARA). The data sought included the specifics of: ALARA programs, training programs, external exposure control, internal exposure control, respiratory protection, surveillance, radioactive waste management, facilities and equipment, and external dose analysis. The results of the study indicated the following: The Radiation Protection and ALARA programs at the three commercial LLW disposal sites were observed to be adequate in scope and content compared to similar programs at other types of nuclear facilities. However, it should be noted that there were many areas that could be improved upon to help ensure the health and safety of occupationally exposed individuals.

  14. Towards the development of an ALARA culture

    International Nuclear Information System (INIS)

    The ALARA principle, which states, for each exposure situation, that doses must be kept As Low As Reasonably Achievable, taking into account economic and social factors' represents the basis of the > developed to manage the radiological risk in a responsible manner. The practical implementation of the ALARA principle is complex. It requires defining transaction mechanisms which enable a responsible management of the radiological risk, taking into account, among other things, possible risk transfers in groups and the allocation of protection resources. The players who can take part in radiological risk management are numerous and have different functions: from the authorities to exposed workers, together with company managers. They all possess specific knowledge and have objectives which are not necessarily compatible. The transactions and negotiations initiated between these players during decision-taking relative to exposure management will therefore only be efficient and productive if there exists both a mutual comprehension of individual objectives and a readiness to collaborate on a common objective: keeping the residual risk at a level both acceptable to, and accepted by, the various parties involved. A fundamental element of this process therefore lies in the development among the various players concerned of a common culture with respect to radiological risks and the methods used for their management, in order to facilitate transactions by the sharing of a common language and system of values. A possible definition of > could be: >. Based on this statement, the paper presents, illustrated by the experience of the French Utility Electricite de France, the main components which should enter into consideration for the development of an ALARA culture for the management of occupational exposures. It concludes on the necessity to construct and transmit a common patrimony of a radiological risk management system comprising the scientific and technical knowledge

  15. Comments on two American justice decisions founded on ALARA

    International Nuclear Information System (INIS)

    The role of the ALARA principle in the American justice is considered as a very important part of the law in evolution. The first decision called 'James decision' was the case of a worker who received a dose under the dose limit and was agreed in his demand. The second one,'Three Miles Island decision', was to refuse the ALARA principle as a norm because it would consider that the justice is more able to pilot a nuclear power plant than competent authorities. These two examples show that the ALARA principle must stay an operational guide and not a legal norm of precautions susceptible to impose sanctions by justice. (N.C.)

  16. Fuel transfer system ALARA design review - Project A.15

    International Nuclear Information System (INIS)

    One mission of the Spent Nuclear Fuel (SNF) Project is to move the SNF from the K Basins in the Hanford 100K Area to an interim dry storage at the Canister Storage Building (CSB) in the Hanford 200 East Area. The Fuel Transfer System (FTS) is a subproject that will move the SNF from the 105K East (KE) Facility to the 105K West (KW) Facility. The SNF will be treated for shipment to the Cold Vacuum Drying (CVD) facility at the KW Basin. The SNF canisters will be loaded underwater into a Shielded Transfer Cask (STC) in the KE Basin. The fully loaded STC will be brought out of the water and placed into a Cask Transfer Overpack (CTO) by the STC Straddle Carrier. As the STC is removed from the water, it will be washed down with demineralized water by an manual rinse system. The CTO with the STC inside will be placed on a transport trailer and transferred to the KW Basin as an intra-facility transfer. The CTO will be unloaded from the shipping trailer at the KW Basin and the STC will be removed from the CTO. The STC will then be lowered into the KW Basin water and the fuel will be removed. The SNF will then be processed for shipment to the CVD. As soon as all of the fuel has been removed from the STC, the cask will be removed from the KW Basin water and placed into the CTO. The CTO will again be placed on the trailer for transport back to the KE Basin where the entire cycle will be repeated approximately 400 times. This document records the As Low As Reasonably Achievable (ALARA) findings and design recommendations/requirements by the SNF Project noted during the Final Design Review of the STC, CTO, STC Transfer System, Annexes and Roadways for support of FTS. This document is structured so that all statements that include the word ''shall'' represent design features that have been or will be implemented within the project scope. Statements that include the words ''should'' or ''recommend'' represent ALARA design features to be evaluated for future implementation

  19. ALARA ASSESSMENT OF SETTLER SLUDGE SAMPLING METHODS

    International Nuclear Information System (INIS)

    The purpose of this assessment is to compare underwater and above water settler sludge sampling methods to determine if the added cost for underwater sampling for the sole purpose of worker dose reductions is justified. Initial planning for sludge sampling included container, settler and knock-out-pot (KOP) sampling. Due to the significantly higher dose consequence of KOP sludge, a decision was made to sample KOP underwater to achieve worker dose reductions. Additionally, initial plans were to utilize the underwater sampling apparatus for settler sludge. Since there are no longer plans to sample KOP sludge, the decision for underwater sampling for settler sludge needs to be revisited. The present sampling plan calls for spending an estimated $2,500,000 to design and construct a new underwater sampling system (per A21 C-PL-001 RevOE). This evaluation will compare and contrast the present method of above water sampling to the underwater method that is planned by the Sludge Treatment Project (STP) and determine if settler samples can be taken using the existing sampling cart (with potentially minor modifications) while maintaining doses to workers As Low As Reasonably Achievable (ALARA) and eliminate the need for costly redesigns, testing and personnel retraining

  20. The optimization (ALARA) problem: A direct formulation

    International Nuclear Information System (INIS)

    An alternative method to that set out by the International Commission on Radiological Protection (ICRP) for implementing the optimization (ALARA) principle of radiation protection is proposed. The method follows directly from the basic dose limitation system and naturally integrates the three components of the system. An essential feature of the method is that 'all exposures' is taken to mean 'each and every one' rather than the 'sum of individual doses', as in the usual method using the collective dose concept. The method draws on established techniques from optimization theory and those aspects of micro-economic theory which form the basis of cost-benefit analysis. The method takes separate account of both the direct costs to the community of the effects of radiation exposures and each individual's 'risk-benefit' attitudes to radiation exposures. The conundrum concerning the 'value of a life' turns out to be operationally and quantitatively irrelevant. Various constraints including the dose limits, economic and social constraints and natural physical constraints are included in the method which leads directly to a standard form problem in mathematical programming. A practical advantage of the method is that it is conceptually consistent with the operational methods used and judgements made regularly by health physicists and radiation safety officers. While the proposed method allows an optimization problem to be readily specified, it does require some familiarity with optimization solution techniques in larger applications.

  1. Incremental ALARA cost/benefit computer analysis

    International Nuclear Information System (INIS)

    Commonwealth Edison Company has developed and is testing an enhanced Fortran Computer Program to be used for cost/benefit analysis of Radiation Reduction Projects at its six nuclear power facilities and Corporate Technical Support Groups. This paper describes a Macro-Diven IBM Mainframe Program comprised of two different types of analyses-an Abbreviated Program with fixed costs and base values, and an extended Engineering Version for a detailed, more through and time-consuming approach. The extended engineering version breaks radiation exposure costs down into two components-Health-Related Costs and Replacement Labor Costs. According to user input, the program automatically adjust these two cost components and applies the derivation to company economic analyses such as replacement power costs, carrying charges, debt interest, and capital investment cost. The results from one of more program runs using different parameters may be compared in order to determine the most appropriate ALARA dose reduction technique. Benefits of this particular cost / benefit analysis technique includes flexibility to accommodate a wide range of user data and pre-job preparation, as well as the use of proven and standardized company economic equations

  2. Note--A Mathematical Model for Evaluating Cross-Sales Policies in Telephone Service Centers

    OpenAIRE

    Reynold E. Byers; Kut C. So

    2007-01-01

    Cross-selling in telephone service centers is seen by industry as a useful means to generate profits from an existing customer base. Introducing cross-sales to a service center, however, needs to be properly managed as it could degrade customer service quality. Real-time customer and system information can be used to set the appropriate control policy for cross-sales to enhance profitability without causing undesirable service degradation for calling customers. The objective of this paper is ...

  3. Computer code for quantitative ALARA evaluations

    International Nuclear Information System (INIS)

    A FORTRAN computer code has been developed to simplify the determination of whether dose reduction actions meet the as low as is reasonably achievable (ALARA) criterion. The calculations are based on the methodology developed for the Atomic Industrial Forum. The code is used for analyses of eight types of dose reduction actions, characterized as follows: reduce dose rate, reduce job frequency, reduce productive working time, reduce crew size, increase administrative dose limit for the task, and increase the workers' time utilization and dose utilization through (a) improved working conditions, (b) basic skill training, or (c) refresher training for special skills. For each type of action, two analysis modes are available. The first is a generic analysis in which the program computes potential benefits (in dollars) for a range of possible improvements, e.g., for a range of lower dose rates. Generic analyses are most useful in the planning stage and for evaluating the general feasibility of alternative approaches. The second is a specific analysis in which the potential annual benefits of a specific level of improvement and the annual implementation cost are compared. The potential benefits reflect savings in operational and societal costs that can be realized if occupational radiation doses are reduced. Because the potential benefits depend upon many variables which characterize the job, the workplace, and the workers, there is no unique relationship between the potential dollar savings and the dose savings. The computer code permits rapid quantitative analyses of alternatives and is a tool that supplements the health physicist's professional judgment. The program output provides a rational basis for decision-making and a record of the assumptions employed

  4. Westinghouse Hanford Company ALARA year-end report, Calendar Year 1994: Revision 3A, Radiological engineering and ALARA

    International Nuclear Information System (INIS)

    It has long been the US Department of Energy's (DOE's) Policy that radiation doses should be maintained as far below the dose limits as is reasonably achievable. This policy, known as the ''ALARA Principle of radiation protection,'' maintains that radiation exposures should be maintained as low as reasonably achievable, taking into account social, technical, economic, practical, and public policy considerations. The ALARA Principle is based on the hypothesis that even very low radiation doses carry some risk. As a result, it is not enough to maintain doses at/or slightly below limits; the lower the doses, the lower the risks. Because it is not possible to reduce all doses at DOE facilities to zero, economic and social factors must be considered to determine the optimal level of radiation doses. According to the ALARA Principle, if doses are too high, resources should be well spent to reduce them. At some point, the resources being spent to maintain low doses are exactly balanced by the risks avoided. Reducing doses below this point results in a misallocation of resources; the resources could be spent elsewhere and have a greater positive impact on health and safety. The objective of the Westinghouse Hanford Company (WHC) ALARA/Contamination Control Improvement Project (CCIP) Program is to manage and control exposures (both individual and collective) to the work force, the general public, and the environment to levels as low as is reasonable using the aforementioned ALARA Principle

  5. Report on the PWR-radiation protection/ALARA Committee

    International Nuclear Information System (INIS)

    In 1992, representatives from several utilities with operational Pressurized Water Reactors (PWR) formed the PWR-Radiation Protection/ALARA Committee. The mission of the Committee is to facilitate open communications between member utilities relative to radiation protection and ALARA issues such that cost effective dose reduction and radiation protection measures may be instituted. While industry deregulation appears inevitable and inter-utility competition is on the rise, Committee members are fully committed to sharing both positive and negative experiences for the benefit of the health and safety of the radiation worker. Committee meetings provide current operational experiences through members providing Plant status reports, and information relative to programmatic improvements through member presentations and topic specific workshops. The most recent Committee workshop was facilitated to provide members with defined experiences that provide cost effective ALARA performance

  6. Experiences in ALARA application: 7th parade of maintenance

    International Nuclear Information System (INIS)

    The achieved experience with these activities, and all the carried out during the seventh stop but that they are not included here, carried to take a serie of decisions in the ALARA group, of which can be mentioned the following: 1. Definition of goals of collective dose and singular for works, to complete the ALARA commitment toward the occupational exposure personnel of the CLV. 2. To analyze the obtained information, as quick as possible, for using it in similar situations of work (to normalize the obtained results, when this is possible. 3. To coordinate the activities in those that participate different work groups with the end of not hindering the development of the same ones. 4. To establish ALARA responsibles of the works to fulfill functions of: pursuit of the work and information to the workers for their safety

  7. Pacific Northwest Laboratory ALARA Report for Calendar Year 1993

    International Nuclear Information System (INIS)

    This report provides summary results of the Calendar Year (CY) 1993 As Low As Reasonably Achievable (ALARA) Program at the Pacific Northwest Laboratory (PNL). This report includes information regarding whole-body exposures to radiation, and skin contaminations. The collective whole-body radiation dose to employees during 1993 was 0.58 person-sievert (58 person-rem). This dose was 11 percent lower than the projected dose of 0.65 person-sievert (65 person-rem). The Radiation Protection Section's Field Dosimetry Services group projected that no PNL employee's dose would exceed 0.02 sievert (2 rem) based on dosimeters processed during the year; no worker actually exceeded the limit by the end of CY 1993. There were 15 reported cases of skin contamination for PNL employees during 1993. This number of 60 percent of the projected total of 25 cases. There were an additional 21 cases of personal-effects contamination to PNL staff: Nine of these contamination events occurred at the 324 Building, nine occurred at the 325 Building, one occurred in the 327 Building, one occurred in the 3720 Building, and one occurred in the 326 Building. Line management set numerous challenging and production ALARA goals for their facilities. Appendix A describes the final status of the 1993 ALARA goals. Appendix B describes the radiological ALARA goals for 1994. The Radiation Protection Section of the Laboratory Safety Dept. routinely perform audits of radiological ALARA requirements for specific facilities with significant potential for exposure. These ALARA audits are part of a comprehensive safety audit of the facility, designed to evaluate and improve total safety performance

  8. VISIPLAN 3D ALARA planning and communication tool

    International Nuclear Information System (INIS)

    Human operations are required in nuclear installation, during maintenance, outage, repair and decommissioning. This leads to the exposure of the worker to radiation. It is clear that these operations must be performed according to the ALARA principle (to reduce the dose As Low As Reasonably Achievable). The person responsible for planning the job needs to evaluate different scenarios based on the exposure of the worker. This involves the manipulation of a lot of information specific to the work place such as the geometry, materials, radiological and technical boundary conditions to assess the dose. A lot of communication between the ALARA stakeholders is needed during this pre-job study. A communication that can be cumbersome and tedious when based on written documents and paper plans. The use of 3D calculation and simulation tools provide a solution to this problem. They provide an excellent means to make the above mentioned process more efficient and effective by calculating and visualising the environment and the associated radiological risk. The VISIPLAN 3D ALARA planning tool is developed and designed by SCK-CEN as a dose assessment tool enabling the user to calculate the dose in a 3D environment for work scenarios. This software is very successful in the ALARA field. At present 22 companies in Europe use the VISIPLAN software in the field of dose assessment in maintenance and decommissioning. Recent developments and applications are discussed

  11. Designing plants for ALARA-revelation or evolution

    International Nuclear Information System (INIS)

    The author traces the Duke Nuclear program from the late 1960s to today. He then looks at the future. The primary goal, he says, should be to continue to reduce individual exposure in order to reduce total station, industry exposure. In order to accomplish this goal in the design process, he recommends continued training of design personnel to reinforce the ALARA concepts and to provide new industry techniques and actual examples

(LANL), Los Alamos, NM (United States)

    2016-03-29

    Los Alamos National Laboratory (LANL) ensures that radiation exposures to members of the public and the environment from LANL operations, past and present, are below regulatory thresholds and are as low as reasonably achievable (ALARA) through compliance with DOE Order 458.1 Radiation Protection for the Public and the Environment, and LANL Policy 412 Environmental Radiation Protection. In 2007, a finding (RL.2-F-1) and observation (RL.2-0-1) in the NNSA/ LASO report, September 2007, Release of Property (Land) Containing Residual Radioactive Material Self-Assessment Report, indicated that LANL had no policy or documented process in place for the release of property containing residual radioactive material. In response, LANL developed PD410, Los Alamos National Laboratory Environmental ALARA Program. The most recent version of this document became effective on September 28, 2011. The document provides program authorities, responsibilities, descriptions, processes, and thresholds for conducting qualitative and quantitative ALARA analyses for prospective and actual radiation exposures to the public and t o the environment resulting from DOE activities conducted on the LANL site.

  13. Effective use of metrics in an ALARA program

    International Nuclear Information System (INIS)

    ALARA radiological protection programs require metrics to meet their objectives. Sources of metrics include; external dosimetry; internal dosimetry; radiological occurrences from the occurrence reporting and processing system (ORPS); and radiological incident reports (RIR). The sources themselves contain an abundance of specific ''indicators''. To choose the site-specific indicators that will be tracked and trended requires careful review. This required the end users to expend valuable time and effort to locate the data they needed. To address this problem, a central metrics database has been developed so that customers can have all their questions addressed quickly and correctly. The database was developed in the beginning to answer some of the customer's most frequently asked questions. It is now also a tool to communicate the status of the radiation protection program to facility managers. Finally it also addresses requirements contained in the Rad Con manual and the 10CFR835 implementation guides. The database uses currently available, ''user friendly'', software and contains information from RIR's, ORPS, and external dosimetry records specific to ALARA performance indicators. The database is expandable to allow new metrics input. Specific reports have been developed to assist customers in their tracking and trending of ALARA metrics

  14. ALARA approach on Qinshan unit I lower internals recovery project

    International Nuclear Information System (INIS)

    Qinshan unit-1 is a 300 Mwe prototype PWR. It has been successfully operating for 4 fuel cycles about 10 years. Some loose parts by the failure of the guide tube of the reactor core neutron flux measurement thimble were observed on the lower structure of Core Barrel during periodical inspection after unloading all fuel assemblies. Qinshan Nuclear Power Company selected Westinghouse Electric Company as contractor to perform the reactor core barrel recovery service after negotiated with 4 world big company. QNPC and Westinghouse worked together to approach the ALARA by increasing water shielding, adding additional steel shielding, fuel pool cleaning and using the long hand tools, remote camera system. The training, mock-up exercise, good personal behavior was greatly contributed to the ALARA approaching. The collective dose and personal exposure of this job were successful controlled by implementing the preset ALARA program. The job was done by the cost of 70 man.mSv collective dose and 3.5 mSv maximum personal exposure despite of the high dose-rate which hot spot in some place is up to several hundred Sv per hour.

  15. ALARA and reactor shutdown organization in foreign countries

    International Nuclear Information System (INIS)

    To have an ALARA policy at EdF, the CEPN realized a study on unit shutdown organization and the place of radiation protection in four nuclear power plants: Ringhals (Sweden), Philippsburg (Germany), Koeberg (South Africa) and Clinton (Usa). These sites have common characteristics such strong integration of radiation protection in any phases of shutdown, a collaboration between services, a decision power given to radio protectionists and a real motivation to reduce exposure at any level of operators. Each site uses a radiological working license for intervention in controlled area. 5 refs

  16. Cost-effectiveness studies as part of an ALARA program

    International Nuclear Information System (INIS)

    Recent studies of cost effectiveness of engineering modifications for dose reduction at nuclear power plants conducted at BNL will be considered in this report. Since each of these items has the potential for a 50% to 60% reduction in collective dose, it appears there is large potential for dose reduction from engineering type modifications. The question that must be answered for each plant is ''which modifications or improvements are required for optimization (ALARA). The purpose of this paper is to illustrate that quantified optimization need not be costly and can often be highly beneficial

  19. Experience and new developments in implementing ALARA in occupational, public and patient exposures. Summary and recommendations of the 10. european ALARA network workshop

    International Nuclear Information System (INIS)

    The 10. european ALARA network (E.A.N.) workshop took place in Prague (Czech Republic) in September 2006. This was the 10-year anniversary of the E.A.N., and unlike the previous workshops that addressed a particular ALARA topic, the aim of this workshop was to consider the implementation of the optimisation principle in all domains of activities (nuclear and conventional industry, medical sector, NORM industry). This principle is fundamental to radiation protection, and the workshop drew together key stakeholders to discuss its past, present and future status. The workshop was asked to consider the practical implementation of ALARA, and how this might be improved in the next 10 years. The objectives of the 10. E.A.N. workshop were to review the past evolution of the ALARA concept, internationally, within the Eu, and nationally, in terms of the practical impact on radiation protection; to examine the current status of the implementation of the ALARA principle; and to identify needs for future developments in the concept and implementation of optimisation. As with previous workshops, half the programme time was devoted to invited presentations, and half to working group discussions and report backs. After discussion, the output of these working groups was collated by the E.A.N. co-computers, to produce seven formal recommendations to international organizations (IAEA, International Labour Organisation, European Commission), to E.A.N. itself and to national authorities. These recommendations deal with justification of practices, holistic approach, ALARA culture, ALARA training, especially in the medical sector, ALARA focus through inspection and control, and stakeholder involvement.

  20. ALARA issues arising for safety and security of radiation sources and security screening devices - Summary and recommendations of the 12. European ALARA network workshop

    International Nuclear Information System (INIS)

    The 12. European ALARA Network (EAN) workshop on 'ALARA issues arising for safety and security of radiation sources and security screening devices' took place in Vienna (Austria) in October 2009. The aim of that workshop was to consider how the implementation of ALARA3, in terms of planned and emergency situations, involving worker and public doses, is affected by the introduction of security-related measures. In the case of new equipment and procedures, there was also the question of whether exposures arising from security screening devices can be justified and optimised. This workshop consisted of invited oral presentations, which highlighted the main issues, and half of the programme was devoted to discussions within working groups on specific topics. During their discussions, the working groups identified recommendations dealing with the following topics: the implementation of the Code of Conduct and HASS4 - ensuring ALARA; balancing security and safety - how to achieve an optimum solution; the management of an emergency exposure situation from an ALARA perspective; the justification and optimisation of the use of security devices. The objective of this paper is to present the main conclusions and recommendations produced during the workshop. Individual presentations (papers and slides) as well as the reports from the working groups are available to download on the EAN web site (http://www.eu-alara.net). (authors)

  1. ALARA studies on spent fuel and waste casks

    Energy Technology Data Exchange (ETDEWEB)

    Sutherland, S.H.

    1980-04-01

    In this report, some implications of applying the ALARA concept to cask designs for transporting spent fuel, high-level commercial and defense waste, and remote-handled transuranic waste are investigated. The XSDRNPM, one-dimensional radiation transport code, was used to obtain potential shield designs that would yield total dose rates at 1.8 m from the cask surface of 10, 5, and 2 mrem/h. Gamma shields of depleted uranium, lead, and steel were studied. The capacity of the casks was assumed to be 1, 4, or 7 elements or canisters, and the wastes were 1, 3, 5, and 10 years old. Depending on the dose rate, the cask empty weights and lifetime transportation costs were estimated.

  3. Application of ALARA principles to shipment of spent nuclear fuel

    International Nuclear Information System (INIS)

    The public exposure from spent fuel shipment is very low. In view of this low exposure and the perfect safety record for spent fuel shipment, existing systems can be considered satisfactory. On the other hand, occupational exposure reduction merits consideration and technology improvement to decrease dose should concentrate on this exposure. Practices that affect the age of spent fuel in shipment and the number of times the fuel must be shipped prior to disposal have the largest impact. A policy to encourage a 5-year spent fuel cooling period prior to shipment coupled with appropriate cask redesign to accommodate larger loads would be consistent with ALARA and economic principles. And finally, bypassing high population density areas will not in general reduce shipment dose

  4. The ALARA project of the EDF nuclear park exploitation

    International Nuclear Information System (INIS)

    To bring the exploitation of the nuclear park of EDF at the level of the best exploiters in the world in matter of collective and individual dosimetry, the ALARA principle coordinates numerous actions: to associate the temporary societies, to define common language, methods and tools for the whole park to organize a level effect in this area, to optimize the maintenance that is expansive in radiation doses, to make the different levels of management responsible on dosimetric stakes, to reduce the singular sources of exposure, to assure the organisation and exploitation of the experience back in this field and adapt consequently the system of information. The results are cheerful and the objectives for 2000 are: less than 1.2 h.Sv by year and by reactor, no intervener whom annual radiation dose is upper than 20 mSv (out of exceptional case). (N.C.)

  5. Experience of occupational dose ALARA through work management in Korea

    International Nuclear Information System (INIS)

    The occupational dose to radiation workers in nuclear power plants depends on not only plant-specific factors such as design features, materials, water chemistry and other factors related to dose rates but also work management particles. The long-term experience in the nuclear power industry has showed that the work management can be applied for the simultaneous achievement of two conflicting goals for cost saving and occupational dose reduction. KEPCO has been trying to fulfill these two goals through work management since early 1990s, and achieved great success in the occupational dose reduction. In this paper, the work management policy of KEPCO has been briefly described. Work management experiences for steam generator replacement job of Kori 1, RTD bypass line removal job of Kori 3 and 4, and some other important jobs presented in the ALARA workshop held in 1999 were summarized. Then the lessons learned from the experiences were discussed. (author). 9 refs., 3 tabs., 1 fig

  6. Application of the ALARA process in the regulation of nuclear activities

    International Nuclear Information System (INIS)

    In this report the historical and conceptual basis of the ALARA process has been reviewed. The application solely of a prescriptive approach, particularly a rigorous quantitative approach to the decision-making process, has been questioned. While the Committees recognize the value of quantitative techniques they strongly emphasize that application of the ALARA concept is a much broader process for the determination of acceptable levels of protection. An ALARA process should take into account social and economic factors that are not quantifiable and involve representation of all those having a legitimate interest in the results of the process

  7. Digital Dosemeter 'ALARA OD 2 - ORT' Monitoring Assembly

    International Nuclear Information System (INIS)

    Full text: New Croatian radiation protection law regulations are based, among other positive principles, on the principle of establishing the controlled area in which the workers undergo legal and obligatory external occupational dosimetry monitoring. Outside the area the 1 mSv/year level of exposure is not to be exceeded by the operating radiation source. 'ORT' is the common name for the above mentioned 'outside area' which is to be monitored. The new digital dosimeter device ALARA OD, produced by ALARA Instruments Ltd. has the probe sensitive to the background radiation and fast enough to record any change in normal environmental-background radiation field. If user or dosimeter device enter the higher radiation field area or radiation source produces higher radiation output, second mode will separately start to measure the dose which is at least two times higher than the background at the spot. This methodology of measurement was performed one year long with the set of 60 devices on more than 35 X-ray units used for the civil baggage control on the airports and else. The dosimeter device was a part of whole x-ray system, meaning that one device was always on the spot which was recommended from the manufacturer as a spot with highest external exposure possibilities if any at all. Devices integrated the radiation for the whole year (battery cap. 5 years) and the net result is that there is no need for obligatory dosimetry monitoring of the workers and other stuff working with or near such X-ray units because the integrated dose while X-ray units working on the full load did not exceed the 1 mSv/year level.

  13. Determining the open-quotes Rclose quotes in ALARA: A parametric study to establish cleanup criteria

    International Nuclear Information System (INIS)

    This paper describes the use of a tool for establishing criteria for cleanup of low-level radioactive contamination that will result in cost-effective remedial action. Central to this tool is the application of the principles of ALARA (as low as reasonably achievable). ALARA goals are driven by a desire to remediate a site to meet the strictest criteria practicable; to meet economic requirements, waste volumes must be minimized. The result of using this tool is the development of a remedial action program that satisfies ALARA requirements while limiting health and environmental risks to acceptable levels. Topics discussed in depth include the ALARA process, its principles, and its application to remedial action programs. The paper concludes with a case study in which the tool is applied to establishing cleanup criteria for the Department of Energy's Formerly Utilized Sites Remedial Action Program (FUSRAP)

After a short description of the ALARA principle, it describes the proposition for French sites. They are grouped according to the following: motivation, organisation, means. They are illustrated by the example of steam generator replacement. Three special points concerning preparation of the site are developed: education; training of operators; review of the project

  16. Ten years of ALARA experience in commercial nuclear pharmacy

    International Nuclear Information System (INIS)

    The objective of this study was to review ten years of extremity exposure in a growing nuclear pharmacy company and determine those practices that have been most effective in keeping exposures ALARA. The focus of this study was specifically on extremity exposure since whole body exposures have not been as significant. Methods: More than 400 dispensing employees are monitored weekly for extremity exposure. Currently, these employees handle and dispense more than 9,000 Curies (333,000 GBq) of activity ready for use in nuclear medicine procedures each week. The quarterly and annual extremity exposure histories were examined and compared with the introduction of different initiatives to limit these exposures. Changes in the total activity per unit dose were considered as well as the introduction of different compounding practices during this time. An attempt was made to also determine specifically which activities contribute most to the extremity exposure of a dispenser. Procedural changes were reviewed as well as engineering controls such as new shielding materials and designs. Results: A significant conversion of cardiac doses occurred during the time period evaluated. Tc-99m heart agents became the preferred radiopharmaceutical replacing a significant portion of Tl-201 that had been used previously. Tl-201 is still used often in conjunction with a Tc-99m agent. The significance of the switch is the high percentage of dispensed doses for cardiac studies and the higher activities of the Tc-99m agents. A combination of procedural changes and engineering controls (primarily tungsten shielding devices) have been effective in preventing the extremity exposure increase one might expect based on higher activities dispensed per unit dose and the higher energy of Tc-99m compared to Tl-201. One procedural change, the mandatory use of tongs for handling unshielded syringes of radiopharmaceuticals, resulted in a 17% reduction in the average exposure to the extremities

  17. Application of the ALARA principle to the bleed condenser relief valve replacement project

    International Nuclear Information System (INIS)

    Darlington Nuclear Generating Division's achievements in radiation dose performance can be attributed, in part, to adherence to the ALARA principle. The station's ALARA program, which is an integral part of the safety culture, derives its strength from a strong and unwavering commitment by the site Vice President. This commitment is supported by performance standards and an accountability system which holds managers and supervisors responsible for dose performance. A LAN-based hazard and dose information system with site-wide accessibility was established to facilitate work planning and exposure control. The principle of dose optimization is fully integrated into the work management process and includes work planning, progress monitoring and post-job review. An integrated performance assessment and reporting system also provides timely feedback to management on dose performance. An example of the ALARA program was the bleed condenser relieve valve replacement project. Pre-job ALARA review meetings for the project were held with supervisory staff and technicians to discuss job details and dose reduction measures. All work groups were required to prepare a detailed step be step task safety analysis (TSA). The trades and engineering staff were requested to critique the TSA and suggest ways of reducing dose. Over 30 practical ALARA suggestions were received and adopted for implementation. Daily meetings were held to review job progress and the effectiveness exposure control. A post-job ALARA review was held at the conclusion of each project to obtain feedback and lessons learned. All improvement suggestions were reviewed for implementation during subsequent installations. As a result of the ALARA initiatives, significant dose savings were achieved. The normalized dose expenditure has been reduced from 9.6 rem for the first installation to 6.9 rem for the fourth and last installation. (author)

  18. A note on the puzzling spindown behavior of the Galactic center magnetar SGR J1745-2900

    Tong, Hao

    2015-09-01

    SGR J1745-2900 is a magnetar near the Galactic center. X-ray observations of this source found a decreasing X-ray luminosity accompanied by an enhanced spindown rate. This negative correlation between X-ray luminosity and spindown rate is hard to understand. The wind braking model of magnetars is employed to explain this puzzling spindown behavior. During the release of magnetic energy of magnetars, a system of particles may be generated. Some of these particles remain trapped in the magnetosphere and may contribute to the X-ray luminosity. The rest of the particles can flow out and take away the rotational energy of the central neutron star. A smaller polar cap angle will cause the decrease of X-ray luminosity and enhanced spindown rate of SGR J1745-2900. This magnetar is shortly expected to have a maximum spindown rate.

  19. Man-rem audit - a tool for exposure ALARA at Madras Atomic Power Station

    International Nuclear Information System (INIS)

    ALARA - acronym for As Low As Reasonably Achievable, which means making every reasonable effort to maintain exposures to radiation as far below the dose limits as is practical. ICRP has recommended ALARA to be implemented as a formal practice into the System of Dose Limitation, which contains three parts, 1) Justification of practice 2) Optimization 3) Dose Limits. As with the human endeavor, there is always room for improvement. Keeping this in mind, ALARA program is being practiced in our Nuclear Power Plants over the years. There has been a gradual reduction of collective dose in our Nuclear Power Plants due to successful implementation of the ALARA programs. This was possible due to the rigorous application of O and M experience, feedback and active participation of workforce towards ALARA. Furthermore, ALARA is an ongoing continual improvement programme towards collective dose reduction and has enough scope for improvement at any point of time. In order to substantiate the gains of ALARA programme and to improve it further, first time Mam-rem Audit was conducted at MAPS during the month of Sep-Oct 2010. This paper gives the brief outline about the method man-rem audit, its findings, corrective action implementation and the benefits derived from it. Man-rem audit similar to financial audit, serves as a tool for finding out grey areas where improvements is required so that station collective dose can be further optimized. It is one of the identified missions to achieve excellence in area of reducing station collective dose, unplanned exposures and RPP deviation. The scope of this audit is to bring further improvements in the reduction in station collective dose, create more awareness among the employees about ALARA principles and seek valuable suggestions for improvements. Audit team consisting of senior HP persons had one to one interaction with the individuals of the respective section in the field and tried to gather the information from the individual and

    International Nuclear Information System (INIS)

    In the August 1993 Health Physics Society (HPS) newsletter, the HPS Scientific and Public Issues Committee published a Position Statement entitled open-quotes Radiation Protection of the Public and the Environment.close quotes. In this article, this HPS committee made the statement that they were deeply concerned by the trend for agencies to incorporate the ALARA concept as a regulatory requirements, without providing specific guidance as to what it means and how to implement it consistently. The HPS position paper was in response to the DOE notice on proposed rulemaking for Title 10 Code of Federal Regulations Part 834, open-quotes Radiation Protection of the Public and the Environmentclose quotes (10 CFR 834). In the notice of proposed rulemaking for 10 CFR 834, the Department of Energy (DOE) defined ALARA as follows: open-quotes As used in this part, ALARA is not a dose limit, but rather a process which has the objective of attaining doses as far below the applicable limit of this part as is reasonably achievableclose quotes (10 CFR 834.2, p. 16283 of the Federal Register). The HPS position paper continues, open-quotes The section goes on to elaborate on what is meant by a process without providing sufficient guidance to assure uniform applicability of the process.close quotes. Although this concern is directed towards the ALARA process as it relates to the environment, the Office of Health, which is responsible for occupational workers, shares the same definition for ALARA

  1. Digital Dosemeters - 'ALARA OD' - Personal and Environmental Monitoring Assembly

    International Nuclear Information System (INIS)

    Full text: The importance of prompt dose reporting rises when dose is received within short-time interval or when the radiation source suffers technical failures. New dosimetry concept, where radiation exposure is recognized as a private /or/ group hazard of each person involved in occupational ionizing sources handling, taking into account actual radiation quality of the source, based among other principles, on the principle of establishing the well defined controlled area is introduced. New digital dosemeter device, produced by ALARA Instruments Ltd., measures small occupational doses, including the background. Device is based on ionizing GM tube, a set of modern EEPROM memory chips and Li compound battery set. It operates in two modes and the measurements are continuously performed no matter which mode is on. First mode integrates the dose (including background). If user or dosemeter device enter the higher radiation field area second mode will separately start to measure the dose which is at least two times higher than the surrounding background. The level above which the higher field is considered has to be preprogrammed during the calibration of device. Level depends on the workplace type /or/ environmental conditions where the device will be used. Device is suitable as well for the low level measurements and for the high radiation outputs. When used in the stronger fields, several devices can form a field monitoring system. Device is suitable for the various non-occupational purposes. With some telecommunication electronics and technical improvement, this device is usable as a point (Ort) environmental measuring station. Probe is sensitive to the background radiation and it is fast enough to record any change in normal environmental radiation field, send the data to the central station and raise alarm if necessary. We have built a prototype for environmental monitoring connectable to any kind of telecommunication net. (author)

  2. ALARA and decommissioning: The Fort St. Vrain experience

    International Nuclear Information System (INIS)

    The Fort St. Vrain Nuclear Generating Station, the first and only commercial High Temperature Gas Cooled Reactor to operate in the United States, completed initial fuel loading in late 1973 and initial startup in early 1974. Due to a series of non-nuclear technical problems, Fort St. Vrain never operated consistently, attaining a lifetime capacity factor of slightly less than 15%. In August of 1989, the decision was made to permanently shut down the plant due to control rod drive and steam generator ring header failures. Public Service Company of Colorado elected to proceed with early dismantlement (DECON) as opposed to SAFSTOR on the bases of perceived societal benefits, rad waste, and exposure considerations, regulatory uncertainties associated with SAFSTOR, and cost. The decommissioning of Fort St. Vrain began in August of 1992, and is scheduled to be completed in early 1996. Decommissioning is being conducted by a team consisting of Westinghouse, MK-Ferguson, and Scientific Ecology Group. Public Service Company of Colorado as the licensee provides contract management and oversight of contractor functions. An aggressive program to maintain project radiation exposures As Low As Reasonably Achievable (ALARA) has been established, with the following program elements: temporary and permanent shielding contamination control; mockup training; engineering controls; worker awareness; integrated work package reviews communication; special instrumentation; video camera usage; robotics application; and project committees. To date, worker exposures have been less than project estimates. from the start of the project through Februrary of 1994, total exposure has been 98.666 person-rem, compared to the project estimate of 433 person-rem and goal of 347 person-rem. The presentation will discuss the site characterization efforts, the radiological performance indicator program, and the final site release survey plans

  4. Methodology for making environmental as low as reasonably achievable (ALARA) determinations

    International Nuclear Information System (INIS)

    An overall evaluation concept for use in making differential cost-benefit analyses in environmental as low as reasonably achievable (ALARA) determinations is being implemented by Rockwell Hanford Operations. This evaluation includes consideration of seven categories: (1) capital costs; (2) operating costs; (3) state of the art; (4) safety; (5) accident or upset consequences; (6) reliability, operability, and maintainability; and (7) decommissionability. Appropriate weighting factors for each of these categories are under development so that ALARA determinations can be made by comparing scores of alternative proposals for facility design, operations, and upgrade. This method of evaluation circumvents the traditional basis of a stated monetary sum per person-rem of dose commitment. This alternative was generated by advice from legal counsel who advised against formally pursuing this avenue of approach to ALARA for environmental and occupational dose commitments

    2015-06-01

    A review of dosimetry results from 1 January 2010 through 31 December 2014 was conducted to demonstrate that radiation protection methods used are compliant with regulatory limits and conform to the philosophy to keep exposures to radiation As Low As is Reasonably Achievable (ALARA). This included a review and evaluation of personnel dosimetry (external and internal) results at Sandia National Laboratories, New Mexico as well as at Sandia National Laboratories, California. Additionally, results of environmental monitoring efforts at Sandia National Laboratories, New Mexico were reviewed. ALARA is a philosophical approach to radiation protection by managing and controlling radiation exposures (individual and collective) to the work force and to the general public to levels that are As Low As is Reasonably Achievable taking social, technical, economic, practical, and public policy considerations into account. ALARA is not a dose limit but a process which has the objective of attaining doses as far below applicable dose limits As Low As is Reasonably Achievable.

    2000-01-01

    The requirements for the performance of radiological design reviews are codified in 10CFR835, Occupational Radiation Protection. The basic requirements for the performance of ALARA design reviews are presented in the Hanford Site Radiological Control Manual (HSRCM). The HSRCM has established trigger levels requiring radiological reviews of non-routine or complex work activities. These requirements are implemented in site procedures HNF-PRO-1622 and 1623. HNF-PRO-1622 Radiological Design Review Process requires that ''radiological design reviews [be performed] of new facilities and equipment and modifications of existing facilities and equipment''. In addition, HNF-PRO-1623 Radiological Work Planning Process requires a formal ALARA Review for planned activities that are estimated to exceed 1 person-rem total Dose Equivalent (DE). The purpose of this review is to validate that the original design for the PFP Cementation Process ensures that the principles of ALARA (As Low As Reasonably Achievable) were included...

  8. Development of a general framework for the practical implementation of ALARA

    International Nuclear Information System (INIS)

    The concept of optimization of protection of the International Commission on Radiological Protection (ICRP) had its roots in the realization that radiation damage is not solely a threshold phenomenon, so a system of protection could not rely solely on limits. It was originally a qualitative idea that you did what was reasonable to reduce doses in the region below the limits. In Publication 26 of the ICRP the recommendation was in terms of ALARA (as low as reasonably achievable). It seems that there are still a number of problem areas and misconceptions about the practical implementation of ALARA, particularly the relationship between the ALARA requirement, decision-aiding techniques and decisions. The development of a general methodological framework for ALARA studies is primary objective of a joint project between the United Kingdom National Radiological Protection Board and the French Centre d'etude sur l'evaluation de la protection dans le domaine nucleaire, sponsored by the Biology and Health Protection programme of the Commission of the European Communities. Following a review of the underlying concepts, the paper outlines progress made on the general framework in a step-by-step guide to performing ALARA studies. The framework covers the initial structuring of the radiological protection problem; the identification of alternative protection options; the selection and quantification of relevant factors for each option; the use of decision-aiding techniques incorporating judgements on the relative weight assigned to these factors; and subsequent sensitivity analyses. This framework provides a method for carrying out ALARA studies to form a structured input to decisions involving non-radiological aspects. Each stage is described, highlighting problem areas where detailed technical guidance or value judgements are required. (author)

  9. ALARA radiation protection applications at NPP A1 decommissioning using VISPLAN planning tool

    International Nuclear Information System (INIS)

    The SCK.CEN developed during the BR3 reactor decommissioning a graphical interfaced 3D dose assessment tool aimed at the above mentioned dose optimization problems. The tool was improved further and commercialized under the name VISIPLAN 3D ALARA planning tool. The use of VISIPLAN tool at NPP A1 decommissioning was advised by EDF within the IAEA TCP SLR/4008 project missions as a component of a 3D technological chain ensuring acquisition and evaluation of digitized information leading to ALARA optimisation of the developed decommissioning working procedures (see Fig. 1). VISIPLAN license was purchased by IAEA and granted to VUJE and NPP A1 within the IAEA TCP project SLR/4008, covering also the necessary basic and advanced training (at NPP A1 real decommissioning environment), and is currently used by VUJE analysts at NPP A1 decommissioning as an ALARA tool for intervention planning and optimisation. The VISIPLAN allows a fast dose assessment for work planned in a radioactive environment. The calculations are based on a 3D model of the work place. This PC-based tool is user friendly and calculates a detailed dose account for different work scenarios defined by the ALARA analyst, taking into account worker position, work duration and subsequent geometry and source distribution changes. The VISIPLAN methodology is described. The VISIPLAN tool was applied to several ALARA studies carried out by the VUJE within development and analysis of various Work Programs for NPP Al decommissioning tasks. The applications ranged from simpler to complex ALARA planning tasks covering simple shielding applications to selection of the most suitable order of complex working procedures. Removal of inner liners from underground reservoirs 6/1 and 6/2 as well as Dismantling of pipes and components from a (hostile) 60 m corridor are described. (authors)

  12. Dose assessment and dose optimisation in decommissioning using the VISIPLAN 3D ALARA planning tool

    International Nuclear Information System (INIS)

    The optimisation of radiological protection of the workers in nuclear industry is an important part of the safety culture especially in the field of decommissioning where we are confronted with a radioactive environment that is in the process of constant change. The application of the ALARA concept (to keep exposures As Low As Reasonably Achievable) is not always straightforward in such cases. A good ALARA pre-job study must be performed and should contain predicted doses in the work area and investigate the effects of geometry, material, source or work position changes. This information provides a quantitative basis to select between various alternative work scenario's for a specific operation. In order to handle this information SCK-CEN developed the VISIPLAN 3D ALARA planning tool. This PC-based tool makes it possible to create and edit work scenarios taking into account worker positions and subsequent geometry and source distribution changes in a 3D environment. The presentation will show the current status of the tool and its application to the decommissioning of the BR3 reactor and other installations. New developments will also be presented regarding the geometric and radioactive characterisation of a decommissioning site. The use of human motion simulation tools in ALARA assessment will also be discussed. This will show how new developments of software and measurement tools can help dealing with the new challenges of decommissioning in the field of dose optimization. (authors)

  14. Health physics manual of good practices for reducing radiation exposure to levels that are as low as reasonably achievable (ALARA)

    International Nuclear Information System (INIS)

    A primary objective of the US Department of Energy (DOE) health physics and radiation protection program has been to limit radiation exposures to those levels that are as low as reasonably achievable (ALARA). As a result, the ALARA concept developed into a program and a set of operational principles to ensure that the objective was consistently met. Implementation of these principles required that a guide be produced. The original ALARA guide was issued by DOE in 1980 to promote improved understanding of ALARA concepts within the DOE community and to assist those responsible for operational ALARA activities in attaining their goals. Since 1980, additional guidance has been published by national and international organizations to provide further definition and clarification to ALARA concepts. As basic ALARA experience increased, the value and role of the original guide prompted the DOE Office of Nuclear Safety (ONS) to support a current revision. The revised manual of good practices includes six sections: 1.0 Introduction, 2.0 Administration, 3.0 Optimization, 4.0 Setting and Evaluating ALARA Goals, 5.0 Radiological Design, and 6.0 Conduct of Operations. The manual is directed primarily to contractor and DOE staff who are responsible for conduct and overview of radiation protection and ALARA programs at DOE facilities. The intent is to provide sufficient guidance such that the manual, if followed, will ensure that radiation exposures are maintained as low as reasonably achievable and will establish the basis for a formally structured and auditable program. 118 refs., 16 figs., 3 tabs

  16. Development of an ALARA programme based on radiological measurements at a nuclear power plant

    International Nuclear Information System (INIS)

    Application of As Low As Reasonably Achievable (ALARA) approach, recommended by the International Commission on Radiological Protection (ICRP) for the control of radiation exposures of personnel, requires assigning monetary value to the detriment implied in the radiation exposure based on social and economic consideration. It is, however, felt that the global application of such an approach could neither be practical nor be objective in view of the widely differing socio-economic conditions of various countries. In view of these difficulties, an analytical method has been developed to quantify avoidable collective external dose of the work force at a Pressurized Heavy Water Reactor (PHWR) type of Nuclear Power Plant (NPP) in implementing ALARA methodology

  17. ALARA database value in future outage work planning and dose management

    International Nuclear Information System (INIS)

    ALARA database encompassing job-specific duration and man-rem plant specific information over three refueling outages represents an invaluable tool for the outage work planner and ALARA engineer. This paper describes dose-management trends emerging based on analysis of three refueling outages at Clinton Power Station. Conclusions reached based on hard data available from a relational database dose-tracking system is a valuable tool for planning of future outage work. The system's ability to identify key problem areas during a refueling outage is improving as more outage comparative data becomes available. Trends over a three outage period are identified in this paper in the categories of number and type of radiation work permits implemented, duration of jobs, projected vs. actual dose rates in work areas, and accuracy of outage person-rem projection. The value of the database in projecting 1 and 5 year station person-rem estimates is discussed

  18. ALARA Review for the Decontamination, Deactivation and Housekeeping of the 233-S Viewing Room

    International Nuclear Information System (INIS)

    A formal as low as reasonably achievable (ALARA) review is required by BHI-SH-02, Vol. 1, Safety and Health Procedures, Procedure 1.22, 'Planning Radiological Work', when radiological conditions exceed trigger level. The level of contamination inside the viewing room of the 233-S Facility meets this criterion. This ALARA review is for task instructions 1997-03-18-005-8.3.1, 'Instructions for Routine Entries and Minor Maintenance Work at 233-S,' and 8.3.2, 'Instructions for Deactivation, Decon, and Housekeeping in Viewing Room.' The radiological work permit (RWP) request broke the two task instructions into nine separate tasks. The nine tasks identified in the RWP request were used to estimate airborne concentrations and the total exposure

  19. ALARA optimization at decommissioning of NPP A1, Slovak Republic, using advanced radiation protection tools

    International Nuclear Information System (INIS)

    Decommissioning operations effect changes in the environment and lead to situations where occupational doses strongly depend on space distribution of dose rates (DR) and time duration of critical activities. In such cases one needs an adequate geometrical and source model that allows the user to calculate the DR dose exposures. In the end a comparison of doses for alternative sets of work trajectories can lead to the selection of the most adequate scenario with minimised dose burden to the workers. The use of laser scanning with respective as-built 3D modeling software, gamma imagery of the dominant sources and application of 3D ALARA planning tool, VISIPLAN, for the above mentioned purposes was the solution advised by EDF, the technical advisor within the IAEA TCP SLR/4008 project. The above-mentioned components were intended to create a 3D technological chain ensuring acquisition and evaluation of digitized information leading to ALARA optimisation of the decommissioning work procedures. In the case of very complex structures to be modelled for ALARA purposes, an auxiliary code, VISIMODELLER, allows the direct transfer of already existing 3D objects to VISIPLAN. This means the saving of a lot of man-power in drawing the geometry. For gamma imaging and positioning of main sources in the installation the old version gamma camera, ALADIN, owned by NPP A1 was used. Applications of radiation protection techniques at NPP A1 decommissioning project are presented in the paper. These range from simple shielding application by the 3D VISIPLAN planning tool, or creating a 3D as-built model, to ALARA applications for alternative work trajectories in complex geometrical and hostile environment with multiple sources. As examples, removal of plastic liner from large underground reservoirs and removal of contaminated pipes from a long corridor are described in more detail. (author)

  20. Application of the Alara principle to the occupationally exposed workers in nuclear power plants

    International Nuclear Information System (INIS)

    This report sets down how the Alara (as low as reasonably achievable) principle is applied in radiation protection of the occupationally exposed personnel at light-water reactors in EC countries. In some instances the practices, experiences and results from EC countries are supplemented by the practice in other States (e.g. USA, Sweden). Commencing with a short summary of the legal situation in the Member States of the European Community with regard to Alara, the report describes the framework in which the optimization practice has been developed. The main chapters elaborate in detail how the Alara principle has been put into practice in design and operation in LWRs. The importance of qualification and training of power-plant personnel in relation to optimization of radiation protection is considered and some comparisons are drawn with the US practice.

    International Nuclear Information System (INIS)

    This document is designed to provide DOE contractor personnel with general guidance regarding programs and techniques to reduce radiation exposures to as low as reasonably achievable (ALARA). Thus it is directed towards a broad audience, and should have special relevance and interest for operating management as well as radiation protection personnel. It is well recognized that each contractor has needs specific and critical to its radiation protection program. Hence no single set of specific and detailed criteria can be set down as a prescription for achieving the ALARA goal. Rather, general guidance in the form of broad principles is given in order to acquaint management with ALARA needs and concepts. The purpose is to encourage maximum management support of the technical personnel responsible for carrying out day-to-day radiation protection activities. Although primarily written for management, this document also contains technical guidance of potential value to those directly involved in radiation protection activities. Again it should be stressed that what is provided is guidance, and is therefore not mandatory

  3. ALARA review for the decontamination and decommissioning of the 233-S pipe trench

    International Nuclear Information System (INIS)

    The 233-S Facility was completed in 1955 to expand plutonium production by further concentrating the plutonium nitrate product solution from the Reduction Oxidation (REDOX) Plant. The facility is radiologically contaminated because of operations and accidents. Isolation from REDOX and removal of the product transfer lines from the pipe trench is the second step in the decontamination and decommissioning of the entire 233-S Facility. The work scope is to isolate all piping from REDOX and then to remove all the piping/equipment from the pipe trench. The building is presently a Hazard Category 2 Nuclear Facility. A formal as low as reasonably achievable (ALARA) review is required by BHI-SH-02, Vol. 1, Procedure No. 1.22, Planning Radiological Work, when radiological conditions exceed trigger levels. The level of contamination inside the pipe trench and the process fluid piping is unknown. The potential exists to exceed the level of loose surface contamination, which requires a formal ALARA review when opening the pipe trench and cutting of piping commences. This ALARA review is for task instruction 1997-03-18-009 Revision 1, 233-S Pipe Trench Decon and Pipe Removal

  4. ALARA Review of the Spallation Neutron Source Accumulator Ring and Transfer Lines

    The Spallation Neutron Source (SNS) is designed to meet the growing need for new tools that will deepen our understanding in materials science, life science, chemistry, fundamental and nuclear physics, earth and environmental sciences, and engineering sciences. The SNS is an accelerator-based neutron-scattering facility that when operational will produce an average beam power of 2 MW at a repetition rate of 60 Hz. The accelerator complex consists of the front-end systems, which will include an ion source; a 1-GeV full-energy linear accelerator; a single accumulator ring and its transfer lines; and a liquid mercury target. This report documents an as-low-as-reasonably-achievable (ALARA) review of the accumulator ring and transfer lines at their early design stage. An ALARA working group was formed and conducted a review of the SNS ring and transfer lines at the {approx}25% complete design stage to help ensure that ALARA principles are being incorporated into the design. The radiological aspects of the SNS design criteria were reviewed against regulatory requirements and ALARA principles. Proposed features and measures were then reviewed against the SNS design criteria. As part of the overall review, the working group reviewed the design manual; design drawings and process and instrumentation diagrams; the environment, safety, and health manual; and other related reports and literature. The group also talked with SNS design engineers to obtain explanations of pertinent subject matter. The ALARA group found that ALARA principles are indeed being incorporated into the early design stage. Radiation fields have been characterized, and shielding calculations have been performed. Radiological issues are being adequately addressed with regard to equipment selection, access control, confinement structure and ventilation, and contamination control. Radiation monitoring instrumentation for worker and environment protection are also being considered--a good practice at this

  5. ALARA Design Review for the Resumption of the Plutonium Finishing Plant (PFP) Cementation Process Project Activities

    International Nuclear Information System (INIS)

    The requirements for the performance of radiological design reviews are codified in 10CFR835, Occupational Radiation Protection. The basic requirements for the performance of ALARA design reviews are presented in the Hanford Site Radiological Control Manual (HSRCM). The HSRCM has established trigger levels requiring radiological reviews of non-routine or complex work activities. These requirements are implemented in site procedures HNF-PRO-1622 and 1623. HNF-PRO-1622 Radiological Design Review Process requires that ''radiological design reviews [be performed] of new facilities and equipment and modifications of existing facilities and equipment''. In addition, HNF-PRO-1623 Radiological Work Planning Process requires a formal ALARA Review for planned activities that are estimated to exceed 1 person-rem total Dose Equivalent (DE). The purpose of this review is to validate that the original design for the PFP Cementation Process ensures that the principles of ALARA (As Low As Reasonably Achievable) were included in the original project design. That is, that the design and operation of existing Cementation Process equipment and processes allows for the minimization of personnel exposure in its operation, maintenance and decommissioning and that the generation of radioactive waste is kept to a minimum

  10. Report on the BWR owners group radiation protection/ALARA Committee

    International Nuclear Information System (INIS)

    Radiation protection programs at U.S. boiling water reactor (BWR) stations have evolved during the 1980s and early 1990s from a regulatory adherence-based endeavor to a proactive, risk-based radiation protection and prevention mission. The objectives are no longer to merely monitor and document exposure to radiation and radioactive materials. The focus of the current programs is the optimization of radiation protection of occupational workers consistent with the purpose of producing cost-effective electric power. The newly revised 10 CFR 20 defines the term ALARA (as low as reasonably achievable) to take into account the state of technology, the economics of improvements in relation to the state of the technology, and the benefits to the public health and safety. The BWR Owners Group (BWROG) initially formed the Radiation Protection/ALARA Committee in January 1990 to evaluate methods of reducing occupational radiation exposure during refueling outages. Currently, twenty U.S. BWR owner/operators (representing 36 of the operational 37 domestic BWR units), as well as three foreign BWR operators (associate members), have broadened the scope to promote information exchange between BWR radiation protection professionals and develop good practices which will affect optimization of their radiation protection programs. In search of excellence and the challenge of becoming open-quotes World Classclose quotes performers in radiation protection, the BWROG Radiation Protection/ALARA Committee has recently accepted a role in assisting the member utilities in improving radiation protection performance in a cost-effective manner. This paper will summarize the recent activities of this Committee undertaken to execute their role of exchanging information in pursuit of optimizing the improvement of their collective radiation protection performance

  11. Measures to obtain ALARA radiation exposures in ABB Atom BWRs: the BKM project

    International Nuclear Information System (INIS)

    A short review is made of the water chemistry, fuel crud and collective radiation exposure in the ABB Atom BWRs and of a computer simulation study of decontamination strategies. The presented data represent a small selection of results that have been produced by the BKM project in order to investigate how the ALARA concept can be met in a BWR plant. The data show that an annual collective exposure of 0.5 manSv is a realistic target in newer BWR plants. (author)

Good examples of that involvement are the EAN workshops. The stakeholders are involved during the preparation phase, the workshops themselves, the development of recommendations and finally within the follow up actions. More and more categories of stakeholders are interested in topics covered within the EAN, and other similar networks are being set up in other regions. (author)

  16. ALARA plan for the Old Hydrofracture Facility tanks contents removal project at Oak Ridge National Laboratory, Oak Ridge, Tennessee

    International Nuclear Information System (INIS)

    The purpose of the Old Hydrofracture Facility (OHF) Tanks Contents Removal Project is to remove the liquid low-level waste from the five underground storage tanks located at OHF and transfer the resulting slurry to the Melton Valley Storage Tanks facility for treatment and disposal. Among the technical objectives for the OHF Project, there is a specific provision to maintain personnel exposures as low as reasonably achievable (ALARA) during each activity of the project and to protect human health and the environment. The estimated doses and anticipated conditions for accomplishing this project are such that an ALARA Plan is necessary to facilitate formal radiological review of the campaign. This ALARA Plan describes the operational steps necessary for accomplishing the job together with the associated radiological impacts and planned controls. Individual and collective dose estimates are also provided for the various tasks. Any significant changes to this plan (i.e., planned exposures that are greater than 10% of original dose estimates) will require formal revision and concurrence from all parties listed on the approval page. Deviations from this plan (i.e., work outside the scope covered by this plan) also require the preparation of a task-specific ALARA Review that will be amended to this plan with concurrence from all parties listed on the approval page

  17. As low as reasonably achievable (ALARA): is it appropriate for low level exposures?

    International Nuclear Information System (INIS)

    Through various researches and investigations it has been established that high doses of ionizing radiation are harmful to health and there is a linear relationship between dose and the effect. There is substantial controversy regarding the biological and health effects of low doses of ionizing radiation in humans and the biota, in vitro and in vivo despite the large amount of work carried out (both laboratory and epidemiological). By low-level exposure, we mean the exposure to radiation levels comparable to those encountered in the natural environment (ambient radiation level). The proponents of the ALARA policy are the believers of LNT hypothesis adopted by major scientific, official and governmental organizations such as ICRP, NCRP, the NAS-NRC etc. for risk assessment, according to which exposure to any amount of radiation, no matter howsoever small is potentially harmful. The idea that the dose to radiation worker should be As Low As Reasonably Achievable (ALARA) is only appropriate if small doses have a risk. Current radiation risk estimates, drawn by linear extrapolation, from high dose and dose rate of radiation to zero dose, clearly ignore the effects of the repair of DNA- the target of radiation damage. If the hormetic effect is added to the effect predicted by the LNT hypothesis, the resultant effect will be somewhat different from that predicted by the LNT hypothesis alone. Excellent human data show that a moderate increase in background radiation decreases the risk of cancer and significantly increases longevity. There are strong arguments, both experimental and epidemiological, which support the radiation hormesis (beneficial effects of low-level ionizing radiation). In the present paper, we propose to highlight the results of a comprehensive study of the available literature, data and reports of various radiation exposure and protection studies carried out in India and abroad. In conclusion, we find that the radiation hormesis contradicts the

  18. Practical application of the ALARA principle in management of the nuclear legacy: optimization under uncertainty

    International Nuclear Information System (INIS)

    Full text: Radiological protection has a long and distinguished history in taking a balanced approach to optimization. Both utilitarian and individual interests and perspectives are addressed through a process of constrained optimisation, with optimisation intended to lead to the most benefit to the most people, and constraints being operative to limit the degree of inequity among the individuals exposed. At least, expressed simplistically, that is what the recommendations on protection are intended to achieve. This paper examines the difficulties in achieving that objective, based on consideration of the active role of optimisation in regulatory supervision of the historic nuclear legacy. This example is chosen because the application of the ALARA principle has important implications for some very major projects whose objective is remediation of existing legacy facilities. But it is also relevant because timely, effective and cost efficient completion of those projects has implications for confidence in the future development of nuclear power and other uses of radioactive materials. It is also an interesting example because legacy management includes mitigation of some major short and long term hazards, but those mitigating measures themselves involve operations with their own risk, cost and benefit profiles. Like any other complex activity, a legacy management project has to be broken down into logistically feasible parts. However, from a regulatory perspective, simultaneous application of ALARA to worker protection, major accident risk mitigation and long-term environmental and human health protection presents its own challenges. Major uncertainties which exacerbate the problem arise from ill-characterised source terms, estimation of the likelihood of unlikely failures in operational processes, and prospective assessment of radiological impacts over many hundreds of years and longer. The projects themselves are set to run over decades, during which time the

    A comprehensive model of land-surface processes has been under development suitable for use with various National Center for Atmospheric Research (NCAR) General Circulation Models (GCMs). Special emphasis has been given to describing properly the role of vegetation in modifying the surface moisture and energy budgets. The result of these efforts has been incorporated into a boundary package, referred to as the Biosphere-Atmosphere Transfer Scheme (BATS). The current frozen version, BATS1e is a piece of software about four thousand lines of code that runs as an offline version or coupled to the Community Climate Model (CCM).

  20. Managing the radiological risk: ALARA, a principle, an obligation, a state of mind

    International Nuclear Information System (INIS)

    According to the 1993 data published by French nuclear operators and by the Ionizing Radiations Protection Office (OPRI), only two workers have exceeded the maximum annual permissible dose of 50 mSv. However, the respect of dose limits is not a sufficient warranty to accept the ionizing radiations exposure risk. The ALARA (As Low As Reasonably Achievable) principle is a masterpiece of the radiological protection system. Its goal is to maintain the exposures as low as reasonably achievable taking into account the socio-economical constraints. In France, the application of this principle is as compulsory as the respect of dose limits. The proper management and optimization of radiological risk requires the motivation of everybody.

  1. Use of rank sum method in identifying high occupational dose jobs for ALARA implementation

    International Nuclear Information System (INIS)

    The cost-effective reduction of occupational radiation exposure (ORE) dose at a nuclear power plant could not be achieved without going through an extensive analysis of accumulated ORE dose data of existing plants. It is necessary to identify what are high ORE jobs for ALARA implementation. In this study, the Rank Sum Method (RSM) is used in identifying high ORE jobs. As a case study, the database of ORE-related maintenance and repair jobs for Kori Units 3 and 4 is used for assessment, and top twenty high ORE jobs are identified. The results are also verified and validated using the Friedman test, and RSM is found to be a very efficient way of analyzing the data. (author)

  3. ALARA in design and operation of KAIGA-3 and 4, Indian 220 MW(e) PHWR

    International Nuclear Information System (INIS)

    Radiological protection by ALARA in design and operation of nuclear power reactors had made down trend collective dose to occupational workers as well as members of the public. India is operating PHWRs type reactors RAPS onwards and gained a lot of experiences in the design and operation of 100 to 540 MW(e) rated capacity factor. The dose reduction measures have been incorporated into the design of the later reactors based on the operating experiences of earlier reactors. The various components/parts in the design stage have been modified and/or replaced in KAIGA-3 and 4, a long journey of lndian PHWRs operation. The improved operational practices have evolved which resulted in high level of the radiological safety. The radiological safety is ensured by approved guidelines, design improvements, effective shielding, source control, delay/decay of sources, radiation work control, protective equipments, contamination control, ventilation, radioactive waste management, effluent monitoring, work management, training, pep-talk/table-top, ALARA goals/achievements, close review of operational parameters, personal monitoring and other elements. This paper discusses the design and operation improvements of KAIGA-3 and 4 which reduced the Station collective dose and effluent releases. Low ambient gamma radiation field and very low tritium-in-air activity in reactor building has reduced the collective dose compared with similar reactor (KGS-1 and 2 and RAPS-3 and 4) and made record of lowest collective dose. The lowest tritium-in-air activity in accessible/shutdown areas and better fuel management has reduced tritium and FPNG gaseous effluent. The overall radiological safety of KAIGA-3 and 4 maintain low collective dose and insignificant contribution to public dose. The continual improvements in design and operation would bring down collective in the future new 700 MWe IPHWR series

    With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

    For the last six months or so, some of us at The Hastings Center have been participating in a kind of short-term book group. Together we have been thinking about the contribution of moral psychology to bioethics. One of our questions is whether bioethics' understanding of moral values should draw on what moral psychology tells us about moral values. Bioethics tends to look to philosophy for guidance. Can it learn from insights in moral psychology into the biological, environmental, and cultural influences on morality? The question can be taken in many directions. One that I've wrestled with has to do with debates about genetic engineering, where a common concern is that genetic alteration of other organisms, and maybe also of humans, doesn't sit well with the kind of relationship that people want to have to nature.

    Pediatric patients might be as much as 10 times more radiosensitive than adults. Thus, adherence to the principle of "As low as reasonably achievable" (ALARA) represents a practice mandate that minimizes ionizing radiation exposure while optimizing imaging results. This symposium is the third multidisciplinary program that focused on the ALARA principle in pediatric imaging and addressed issues associated with pediatric fluoroscopy and interventional imaging techniques.

  11. ALARA Review of the Activation/Repair of Fire Detectors in Zone Three at the 233-S Facility

    International Nuclear Information System (INIS)

    A formal as low as reasonably achievable (ALARA) review is required by BHI-SH-02, Vol. 1, Procedure 1.22, 'Planning Radiological Work', when radiological conditions exceed trigger levels. The level of contamination inside the viewing room meets this criterion. This ALARA review is for task instruction 1997-03-18-005-8.3.3 (mini task instruction to a living work package), 'Instructions for D ampersand D Support of Fire Detector Troubleshooting and Minor Maintenance Work at 233-S,' and DynCorp 2G-98-7207C, '233-S Reconnect Smoke Detectors Zone 3.' The Radiological Work Permit (RWP) request broke these two task instructions into four separate tasks. The four tasks identified in the RWP request were used to estimate airborne concentrations and the total exposure

    With 5-7 month long duration missions at 51.6° inclination in Low Earth Orbit, the ionizing radiation levels to which International Space Station (ISS) crewmembers are exposed will be the highest planned occupational exposures in the world. Even with the expectation that regulatory dose limits will not be exceeded during a single tour of duty aboard the ISS, the "as low as reasonably achievable" (ALARA) precept requires that radiological risks be minimized when possible through a dose optimization process. Judicious placement of efficient shielding materials in locations where crewmembers sleep, rest, or work is an important means for implementing ALARA for spaceflight. Polyethylene (C nH n) is a relatively inexpensive, stable, and, with a low atomic number, an effective shielding material that has been certified for use aboard the ISS. Several designs for placement of slabs or walls of polyethylene have been evaluated for radiation exposure reduction in the Crew Quarters (CQ) of the Zvezda (Star) Service Module. Optimization of shield designs relies on accurate characterization of the expected primary and secondary particle environment and modeling of the predicted radiobiological responses of critical organs and tissues. Results of the studies shown herein indicate that 20% or more reduction in equivalent dose to the CQ occupant is achievable. These results suggest that shielding design and risk analysis are necessary measures for reducing long-term radiological risks to ISS inhabitants and for meeting legal ALARA requirements. Verification of shield concepts requires results from specific designs to be compared with onboard dosimetry.

  13. Commissioning of experimental enclosures (Hutches) at the Advanced Photon Source - A to Z ALARA

    International Nuclear Information System (INIS)

    The Advanced Photon Source (APS), 7 GeV electron Storage Ring at the Argonne National Laboratory is designed to be a major national user facility providing high-brilliance x-ray beams. Figure 1 shows a plan view of the APS. At completion, APS will have 35 bending magnet (BM) beamlines and 35 insertion device (ID) beamlines. A typical x-ray beamline at APS comprises of a front end (FE) that confines the beam; a first optics enclosure (FOE) which houses optics to filter and monochromatize the beam; and beam transports, additional optics, and the experiment stations.

    As part of its ongoing efforts to reduce doses to workers to levels as low as reasonably achievable (ALARA), Westinghouse Hanford Company (WHC) tasked the Health Protection Department of the Pacific Northwest Laboratory (PNL) to review operations at the 105 K-East Fuel Storage Basin (105 K-East). This review included both routine operations and a proposed campaign to encapsulate N-Reactor fuel stored there. This report summarizes the results of PNL`s reviews of policy, procedures, and practices for operations at 105 K-East as well as an evaluation of the major sources of occupational radiation exposures. Where possible, data previously collected by WHC and its predecessors were used. In addition, PNL staff developed a three-dimensional model of the radiological environment within 105 K-East to assess the relative contributions of different radiation sources to worker dose and to provide a decision tool for use in evaluating alternative methods of dose rate reduction. The model developed by PNL indicates that for most areas in the basin the primary source of occupational radiation exposure is the contaminated concrete surfaces of the basin near the waterline. Basin cooling water piping represents a significant source in a number of areas, particularly the Technical Viewing Pit. This report contains specific recommendations to reduce the impact of these sources of occupational radiation exposure in 105 K-East. Other recommendations to reduce doses to workers during activities such as filter changes and filter sampling are also included.

    The Advanced Photon Source (APS), 7 GeV electron Storage Ring at the Argonne National Laboratory is designed to be a major national user facility providing high-brilliance x-ray beams. Figure 1 shows a plan view of the APS. At completion, APS will have 35 bending magnet (BM) beamlines and 35 insertion device (ID) beamlines. A typical x-ray beamline at APS comprises of a front end (FE) that confines the beam; a first optics enclosure (FOE) which houses optics to filter and monochromatize the beam; and beam transports, additional optics, and the experiment stations. Figure 2 shows a section of the storage ring with the layout of the ID and BM beamlines and typical experiment stations. The first x-ray beam was delivered to an experiment station in 1995. Ever since, to date, over 120 experimental stations (hutches) have been commissioned and are receiving intense x-ray beams of varying energies for various experiments.

  17. INNOVATIVE ALARA TECHNIQUES and WORK PRACTICES USED AT HANFORD FOR D and D

    International Nuclear Information System (INIS)

    The Department of Energy's Hanford Site has several nuclear facilities in the process of decontamination and decommissioning (DandD) with many more to follow. These facilities contain hazardous and highly radioactive materials in plant systems, gloveboxes, hot cells, rooms, collection tanks, ventilation ducts, fuel pools and outside these facilities. Some of the radioactive isotopes are fissile material and have to be closely guarded and require special handling. To safely work in this environment, workers had to learn new skills and develop innovative techniques to decontaminate, remove all equipment and demolish these radioactive work facilities without spreading contamination to the environment. Changing the workscope and worker attitudes involves a culture change for workers, managers, Department of Energy (DOE) and support organizations. DandD involves making different types of risk-based decisions than were made when the plants were operated or sitting dormant. Management involvement, use of the Integrated Safety Management System (ISMS), communications and sharing lessons learned are essential ingredients in developing a successful DandD strategy. New technologies have to be learned including the use of robotic devices and manipulative arms due to high dose rates and amount of radioactive contamination. Minimizing the amount of Transuranic and Mixed radioactive waste and learning how to ship the large quantities of waste are additional skills the Hanford workers have had to learn. DandD work at Hanford is in progress and Hanford Contractors have completed some very difficult and intense DandD work. This presentation will provide information on the best As Low As Reasonably Achievable (ALARA) protective measures, work practices, and the lessons learned to date

  18. ALARA review of the maintenance and repair jobs of repetitive high radiation dose at Kori Unit 3 and 4

    International Nuclear Information System (INIS)

    The policy of maintaining occupational radiation dose (ORD) as low as reasonably achievable (ALARA) requires the effective reduction of ORD in the phases of design as well as operation of nuclear power plants. It has been identified that a predominant portion of ORD arises during maintenance and repair operations at nuclear power plants. The cost-effective reduction of ORD cannot be achieved without a comprehensive analysis of accumulated ORD data of existing nuclear power plants. To identify the jobs of repetitive high ORD, the ORD data of Kori Units 3 and 4 over 10-year period from 1986 to 1995 were compiled into the PC-based ORD database program. As the radiation job classification structure, 26 main jobs are considered, most of which are further subdivided into detailed jobs. According to the order of the collective dose values for 26 main jobs, 10 jobs of high collective dose are identified. As an ALARA review, then, top 10 jobs of high collective dose are statistically analyzed with regard to 1) dose rate, 2) crew number and 3) job frequency that are the factors determining the collective dose for the radiation job of interest. Through the ALARA review, main reasons causing to high collective dose values are identified as follows. The high collective dose of RCP maintenance job is mainly due to the large crew number and the high job frequency. The characteristics of refueling job are similar to those of RCP maintenance job. However, the high collective doses of SG-related jobs such as S/G nozzle dam job, S/G man-way job and S/G tube maintenance job are mainly due to high radiation dose rate. (author)

    The dispositions of operational radiation protection used by the nuclear exploiting societies contribute to the safety of their installations. The Institute of Protection and Nuclear Safety (I.P.S.N.) is led to evaluate these dispositions, particularly the application of the ALARA principle. It appears that it was interesting to make an accounting on the period where the optimization and workers protection were taken into account. The accounting presented in this work is relative to the installations else than power reactors, that is to say: laboratories, fuel cycle facilities, research installations, irradiators. (N.C.)

  1. A corporate ALARA engineering support for all EDF nuclear power plan

    International Nuclear Information System (INIS)

    Since 1991, EDF has established a national ALARA programme with a very effective result in terms of dose reduction. Of course, EDF management has decided to further improve occupational exposure management and dose reduction (both collective and individuals). Since 2002, one key element allowing reaching the new goals, is the set up of a national corporate engineering as a support for EDF sites for preparing maintenance interventions. Its objective is to reduce occupational exposure with the help of up to date tools and methods. That engineering support consists of a growing up team comprising at the moment about ten engineers, including CAD specialists and health physicists. It is in charge of using very efficient tools such as P.A.N.T.H.E.R. -R.P. to perform national modelling studies concerning the reactor and auxiliary buildings areas, which are the most costly in terms of doses. That tool has been developed initially for the first steam generator replacements by EDF S.E.P.T.E.N. engineering department. It uses friendly user 3D software to create a geometrical model of the concerned area with all existing materials (pipes, valves, concrete walls allowing visualizing on personal computers, each area from all perspectives. Other important inputs for P.A.N.T.H.E.R. R.P. are the quantities of radioisotopes present in each material. The code allows then estimating the dose rates at each location in the area, calculating the contribution of each equipment (i.e sources) in the area to the dose rate in each point; calculating also the contribution of each radio isotope to the dose rates. With the help of these models the engineering is then able to perform in depth generic work areas optimisation studies, taking into account the workload in each workstation. Up to recently these studies were performed only for huge operations such as steam generator replacements, they are now proposed to EDF sites for more usual interventions. The selection of these interventions takes

  2. Patient-centered Care.

    Patient-centered care focuses on the patient and the individual's particular health care needs. The goal of patient-centered health care is to empower patients to become active participants in their care. This requires that physicians, radiologic technologists and other health care providers develop good communication skills and address patient needs effectively. Patient-centered care also requires that the health care provider become a patient advocate and strive to provide care that not only is effective but also safe. For radiologic technologists, patient-centered care encompasses principles such as the as low as reasonably achievable (ALARA) concept and contrast media safety. Patient-centered care is associated with a higher rate of patient satisfaction, adherence to suggested lifestyle changes and prescribed treatment, better outcomes and more cost-effective care. This article is a Directed Reading. Your access to Directed Reading quizzes for continuing education credit is determined by your area of interest. For access to other quizzes, go to www.asrt.org/store. According to one theory, most patients judge the quality of their healthcare much like they rate an airplane flight. They assume that the airplane is technically viable and is being piloted by competent people. Criteria for judging a particular airline are personal and include aspects like comfort, friendly service and on-time schedules. Similarly, patients judge the standard of their healthcare on nontechnical aspects, such as a healthcare practitioner's communication and "soft skills." Most are unable to evaluate a practitioner's level of technical skill or training, so the qualities they can assess become of the utmost importance in satisfying patients and providing patient-centered care.(1).

    The irradiated fuel assemblies placed in the storage racks (pools) subject the Boraflex to an intense gamma flux, which causes degradation of the Boraflex arising from the radiolysis reaction and rupture and rearrangement of the chemical bonds by the gamma rays. The decision was taken to remove the Boraflex from the existing racks and reuse them with a neutron absorber, boron steel or borated stainless steel. Throughout this replacement project, the ALARA principle has been applied in developing tools and choosing methods. Each phase was then re-evaluated in terms of dosimetry cost in order to make improvements that would mean a reduction in the dosimetry of the operation. (A.L.B.)

    2002-02-25

    In 2000, Bechtel Jacobs Company LLC (BJC) contracted Tetra Tech NUS, Inc. (TtNUS) and their sub-contractor, Texas World Operations, Inc. (TWO), to plug and abandon (P&A) 111 wells located in the Melton Valley area of Oak Ridge National Laboratory (ORNL). One hundred and seven of those wells were used to monitor fluid movement and subsurface containment of the low level radioactive liquid waste/grout slurry that was injected into the Pumpkin Valley Shale Formation, underlying ORNL. Four wells were used as hydrofracture injection wells to emplace the waste in the shale formation. Although the practice of hydrofracturing was and is considered by many to pose no threat to human health or the environment, the practice was halted in 1982 after the Federal Underground Injection Control regulations were enacted by United States Environmental Protection Agency (USEPA) making it necessary to properly close the wells. The work is being performed for the United States Department of Energy Oak Ridge Operations (DOE ORO). The project team is using the philosophy of minimum waste generation and the principles of ALARA (As Low As Reasonably Achievable) as key project goals to minimize personnel and equipment exposure, waste generation, and project costs. Achievement of these goals was demonstrated by the introduction of several new pieces of custom designed well plugging and abandonment equipment that were tested and used effectively during field operations. Highlights of the work performed and the equipment used are presented.

  19. Reference values of the workers' collective dose unit for the implementation of ''ALARA'' policy in EDF nuclear power plants

    International Nuclear Information System (INIS)

    Implementing the ALARA principle at the design, operation and maintenance stages of EDF's PWRs aims at ensuring a coherent management of individual and collective exposures. The objective of such a policy is, as recommended by ICRP 60, to keep exposures (number of individuals exposed and levels of exposure) as low as reasonably achievable, with an equitable distribution taking into consideration economical and social aspects. This leads EDF to adopt, among other tools, a system of reference monetary values for the unit of collective dose averted. After having recalled the ethical issue associated with such an approach as well as the international consensus on the dose-risk relationship for low doses, the model adopted, integrating risk aversion considerations, is presented. Its main characteristic is a rapid increase of the monetary values with the level of annual individual doses coming close to the regulatory limits. This model will be used as a decision-aiding tool for the evaluation and comparison of alternative protection actions within the optimization process of workers'exposure

    In 2003, the first peroral appendectomy was carried out in a human subject. In order to prevent the premature adoption in clinical practice of the so-called "Natural orifice transluminal endoscopic surgery" (NOTES), a rational framework for its development was proposed in 2005. After animal experimentation, further abdominal interventions were carried out in humans (example: cholecystectomy) through the mouth, vagina, or in a combined approach. The main advantage of NOTES compared to laparoscopic surgery is, from the patient viewpoint, the absence of body scar, but other benefits (example: less pain and costs) could prove to be significant. It is impossible to predict whether or not NOTES will enter in routine clinical practice, but it will generate significant improvements for digestive endoscopy. PMID:18831409

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.

  11. Impact of main radiological pollutants on contamination risks (ALARA) optimisation of physico-chemical environment and retention techniques during operation and shutdown

    International Nuclear Information System (INIS)

    The goal of this paper is to precise the behaviour of different radiochemical species in the primary coolant of PWR plants. Managing these pollutants must lead to limit Reactor Coolant System (RCS) walls 'over-contamination' to decrease the dose rates during the maintenance operations (ALARA). In French Plants, 60Co, silver and antimony represent the major radiochemical pollutants which require a good knowledge of the different phenomena to ensure the lowest contamination risks. The stakes deal with the control and the optimisation of collective and individual doses including waste treatment with low costs. These stakes represent primordial elements of nuclear acceptability.

  14. The necessary guidance on the application of JUSTIFICATION and ALARA by the nuclear authorities, using 'Accountability for Reasonableness' as a decision making process

    International Nuclear Information System (INIS)

    Full text: In all branches of law, but foremost in international nuclear law, the global economic system brings along a vast record of Soft Law covering General Principles and Standards. For a part we can find these Soft Law Principles and Standards back in the clothing of hard law, or in the licensing procedures, at the national level. The larger part however is never 'transposed' into national laws and especially the harmonization, the implementation and control of such Principles and Standards remain doubtful. In this paper the focus lies on JUSTIFICATION and ALARA, as the main nuclear safety principles, accepted world-wide. The regulatory guidance and demonstration of these Principles, indicating which (numerical) safety levels or safety objectives are mandatory and which are only guidance should be undertaken by the international regulators and authorities, but are often lacking. It is the aim of this paper to come up with a better procedural framework for a priority setting process by nuclear authorities. Establishing a fair process for priority setting is easier than agreeing on principles. We use the idea of 'Accountability for Reasonableness', developed in the field of Health Care Management. An ideal model of priority setting within the JUSTIFICATION/ALARA approach will need to specify what should be done (i.e. justified ethically) and how it can be done (i.e. based in empirical reality and on benchmarking), to reach optimal levels of nuclear safety.

  17. When RCRA meets ALARA

    International Nuclear Information System (INIS)

    This paper proposes a method to identify an inconsistency between RCRA and AEA and for distinguishing a true inconsistency from a compliance difficulty. The paper also provides examples of each situation, accommodating specific RCRA requirements to maintain adherence to radiation protection requirements. The proposed method is derived from radiation protection guidance to Federal agencies for occupational exposure that was issued by EPA, under authority derived from Executive Order 10831, the AEA, and Reorganization Plan No. 3 of 1970. This EPA guidance was approved by President Reagan on January 20, 1987 and closely reflects the guidance of national and international radiation standard-setting groups

  18. ALARA and work management

    International Nuclear Information System (INIS)

    At the request of Electricite de France (EDF) and Framatome, the Nuclear Protection Evaluation Centre (CEPN) developed a three-year research project, between 1991 and 1993, to evaluate the impact of various work management factors that can influence occupational exposures in nuclear power plants (NPPs) and to assess the effectiveness of protective actions implemented to reduce them. Three different categories of factors have been delineated: those linked to working conditions (such as ergonomic of work areas and protective suits), those characterizing the operators (qualification, experience level, motivation, etc.). In order to quantify the impact of these factors, a detailed survey was carried out in five French NPPs, focusing on three types of operations: primary valves maintenance, decontamination of reactor cavity, and specialized maintenance operations on the steam generator. This survey was augmented by a literature review on the influence of open-quotes hostileclose quotes environment on working conditions. Finally, a specific study was performed in order to quantify the impact of various types of protective suits used in French nuclear installations according to the type of work to be done. All of these factors have been included in a model aiming at quantifying the effectiveness of protection actions, both from dosimetric and economic point of views

  2. Station Program Note Pull Automation

    Science.gov (United States)

    Delgado, Ivan

    2016-01-01

    Upon commencement of my internship, I was in charge of maintaining the CoFR (Certificate of Flight Readiness) Tool. The tool acquires data from existing Excel workbooks on NASA's and Boeing's databases to create a new spreadsheet listing out all the potential safety concerns for upcoming flights and software transitions. Since the application was written in Visual Basic, I had to learn a new programming language and prepare to handle any malfunctions within the program. Shortly afterwards, I was given the assignment to automate the Station Program Note (SPN) Pull process. I developed an application, in Python, that generated a GUI (Graphical User Interface) that will be used by the International Space Station Safety & Mission Assurance team here at Johnson Space Center. The application will allow its users to download online files with the click of a button, import SPN's based on three different pulls, instantly manipulate and filter spreadsheets, and compare the three sources to determine which active SPN's (Station Program Notes) must be reviewed for any upcoming flights, missions, and/or software transitions. Initially, to perform the NASA SPN pull (one of three), I had created the program to allow the user to login to a secure webpage that stores data, input specific parameters, and retrieve the desired SPN's based on their inputs. However, to avoid any conflicts with sustainment, I altered it so that the user may login and download the NASA file independently. After the user has downloaded the file with the click of a button, I defined the program to check for any outdated or pre-existing files, for successful downloads, to acquire the spreadsheet, convert it from a text file to a comma separated file and finally into an Excel spreadsheet to be filtered and later scrutinized for specific SPN numbers. Once this file has been automatically manipulated to provide only the SPN numbers that are desired, they are stored in a global variable, shown on the GUI, and

  15. Impact of main radiological pollutants on contamination risks (ALARA). Optimisation of physico chemical environment and retention techniques during operation and shutdown

    International Nuclear Information System (INIS)

    The goal of this paper is to follow up the behaviour of different radiochemical species in the primary coolant of PWR plants. Managing these pollutants must lead to limit Reactor Coolant System (RCS) walls 'over-contamination' and consequently to decrease the dose rates during the maintenance operations (ALARA). In French plants, Co 60, silver and antimony represent the major radiochemical pollutants which require a good knowledge of the different phenomena to ensure the lowest contamination risks. The stakes deal with the control and the optimization of collective and individual doses including waste treatment with low costs. These stakes represent primordial elements of nuclear acceptability. It is obvious that implementing specific chemistry and optimizing purification features (filters, resins and flowrate) ensures a limitation of the effects of this type of pollutions. That's why studies are yet in progress to propose operators a chemical policy and adapted procedures for each type of radioactive pollution able to reduce the impact on dosimetry. On the other hand, a new specific gamma spectrometer able to characterize on the field the nature of radioactive deposits, in order to improve the diagnostic, is being developed

  16. Optimization (Alara) and probabilistic exposures: the application of optimization criteria to the control of risks due to exposures of a probabilistic nature

    International Nuclear Information System (INIS)

    The paper described the application of the principles of optimization recommended by the International Commission on Radiological Protection (ICRP) to the restrain of radiation risks due to exposures that may or may not be incurred and to which a probability of occurrence can be assigned. After describing the concept of probabilistic exposures, it proposes a basis for a converging policy of control for both certain and probabilistic exposures, namely the dose-risk relationship adopted for radiation protection purposes. On that basis some coherent approaches for dealing with probabilistic exposures, such as the limitation of individual risks, are discussed. The optimization of safety for reducing all risks from probabilistic exposures to as-low-as-reasonably-achievable (ALARA) levels is reviewed in full. The principles of optimization of protection are used as a basic framework and the relevant factors to be taken into account when moving to probabilistic exposures are presented. The paper also reviews the decision-aiding techniques suitable for performing optimization with particular emphasis to the multi-attribute utility-analysis technique. Finally, there is a discussion on some practical application of decision-aiding multi-attribute utility analysis to probabilistic exposures including the use of probabilistic utilities. In its final outlook, the paper emphasizes the need for standardization and solutions to generic problems, if optimization of safety is to be successful

  8. Lecture Notes on Multigrid Methods

    Energy Technology Data Exchange (ETDEWEB)

    Vassilevski, P S

    2010-06-28

    The Lecture Notes are primarily based on a sequence of lectures given by the author while been a Fulbright scholar at 'St. Kliment Ohridski' University of Sofia, Sofia, Bulgaria during the winter semester of 2009-2010 academic year. The notes are somewhat expanded version of the actual one semester class he taught there. The material covered is slightly modified and adapted version of similar topics covered in the author's monograph 'Multilevel Block-Factorization Preconditioners' published in 2008 by Springer. The author tried to keep the notes as self-contained as possible. That is why the lecture notes begin with some basic introductory matrix-vector linear algebra, numerical PDEs (finite element) facts emphasizing the relations between functions in finite dimensional spaces and their coefficient vectors and respective norms. Then, some additional facts on the implementation of finite elements based on relation tables using the popular compressed sparse row (CSR) format are given. Also, typical condition number estimates of stiffness and mass matrices, the global matrix assembly from local element matrices are given as well. Finally, some basic introductory facts about stationary iterative methods, such as Gauss-Seidel and its symmetrized version are presented. The introductory material ends up with the smoothing property of the classical iterative methods and the main definition of two-grid iterative methods. From here on, the second part of the notes begins which deals with the various aspects of the principal TG and the numerous versions of the MG cycles. At the end, in part III, we briefly introduce algebraic versions of MG referred to as AMG, focusing on classes of AMG specialized for finite element matrices.

    A number of authors have used the portfolio standard deviation to model the risk reduction advantages of naive diversification. Other authors have pointed out that when risk is modelled by the portfolio's variance the modelling process becomes much simpler and is computationally more efficient. In this note we derive an exact parametric relationship between portfolio standard deviation and size and thus highlight the dangers of using the standard deviation in conjunction with O.L.S. regressio...

  10. Functional Centering

    CERN Document Server

    Hahn, M

    1996-01-01

    Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-bound and unbound discourse elements. This claim is backed up by an empirical evaluation of functional centering.

  11. Clinical application of ‘Justification’ and ‘Optimization’ principle of ALARA in pediatric CT imaging: “How many children can be protected from unnecessary radiation?”

    International Nuclear Information System (INIS)

    Highlights: • Practice of ALARA (As Low As Reasonably Achievable) principle in the developed world is currently well established. However, there is striking lack of published data regarding such experience in the developing countries. Therefore, the goal of this study is to prospectively evaluate CT request forms to assess how many children could be saved from harmful radiation exposure if ‘Justification’ and ‘Optimization’ principles of ALARA are applied before obtaining CT imaging in a developing country. • A consecutive 1302 CT request forms over a six month study period (May 16, 2013 to November 15, 2013) in a tertiary pediatric children’s hospital in India were prospectively reviewed by two pediatric radiologists before obtaining CT imaging. First, ‘Justification’ of CT was evaluated and then ‘Optimization’ was applied for evaluation of appropriateness of the requested CT studies. The number (and percentage) of CT studies that was avoided by applying ‘Justification’ and ‘Optimization’ principle of ALARA were calculated. The difference in number of declined and optimized CT requests between CT requests from inpatient and outpatient departments was compared using Chi-Square test. • Based on evaluation of the CT request forms for ‘Justification’ and ‘Optimization’ principle of ALARA by pediatric radiology reviewers, 111 individual anatomic part CT requests from 105 pediatric patients were avoided. Therefore, 8.06% (105 out of 1302 pediatric patients) were saved from unnecessary or additional radiation exposure The rates of declined or optimized CT requests from inpatient department was significantly higher than that from outpatient departments (p < 0.05). • To conclude, a substantial number of pediatric patients, particularly coming from inpatients departments, can be saved from unnecessary or additional radiation exposure from CT imaging when ‘Justification’ and ‘Optimization’ principle of ALARA are applied

    These lecture notes survey some joint work with Samson Abramsky as it was presented by me at several conferences in the summer of 2005. It concerns 'doing quantum mechanics using only pictures of lines, squares, triangles and diamonds'. This picture calculus can be seen as a very substantial extension of Dirac's notation, and has a purely algebraic counterpart in terms of so-called Strongly Compact Closed Categories (introduced by Abramsky and I which subsumes my Logic of Entanglement. For a survey on the 'what', the 'why' and the 'hows' I refer to a previous set of lecture notes. In a last section we provide some pointers to the body of technical literature on the subject

  20. Reduction in airborne contamination levels at the 9201-5 Arc Melt sawing operation. A Y-12 Plant 1982 ALARA goal

    Beck, D.E.; West, C.M.

    1983-02-01

    Lowering the uranium airborne contamination level at the two saws in the 9201-5 Arc Melt Area was chosen as a Y-12 Plant As-Low-As-Reasonably-Achievable (ALARA) goal for 1982. This priority was convincingly communicated to those involving by giving specific instructions to suspend saw operations any time there was evidence of a problem until that problem could be corrected. Using control charts on air flow rates into the saw enclosures and pressure drops across filters in the saw ventilation (Delta Phase I) exhaust system, it was possible to decide when filter changes or other adjustments were necessary to maintain the exhaust flow rates needed for improved airborne contamination control. The keeping of these charts, along with the actions taken on the basis of the data gathered, made it possible to meet the goal of reducing airborne contamination levels in 1982, as compared with 1981, although production in the Arc Melt Area increased significantly. These data also showed that use of one brand of filter in the prefilter system resulted in the need to change filters more frequently than when another brand was used. This fact triggered an investigation which revealed the cause for the shorter useful life of that filter and a request that only specifically approved filters be purchased for use in this system. Use of these control data also made it possible to establish that the exhaust system operated more effectively without the Roto-clone hydrostatic pecipitators because exhaust air flow was increased without reduction in filter life.

  11. Lecture notes for criticality safety

    International Nuclear Information System (INIS)

    These lecture notes for criticality safety are prepared for the training of Department of Energy supervisory, project management, and administrative staff. Technical training and basic mathematics are assumed. The notes are designed for a two-day course, taught by two lecturers. Video tapes may be used at the options of the instructors. The notes provide all the materials that are necessary but outside reading will assist in the fullest understanding. The course begins with a nuclear physics overview. The reader is led from the macroscopic world into the microscopic world of atoms and the elementary particles that constitute atoms. The particles, their masses and sizes and properties associated with radioactive decay and fission are introduced along with Einstein's mass-energy equivalence. Radioactive decay, nuclear reactions, radiation penetration, shielding and health-effects are discussed to understand protection in case of a criticality accident. Fission, the fission products, particles and energy released are presented to appreciate the dangers of criticality. Nuclear cross sections are introduced to understand the effectiveness of slow neutrons to produce fission. Chain reactors are presented as an economy; effective use of the neutrons from fission leads to more fission resulting in a power reactor or a criticality excursion. The six-factor formula is presented for managing the neutron budget. This leads to concepts of material and geometric buckling which are used in simple calculations to assure safety from criticality. Experimental measurements and computer code calculations of criticality are discussed. To emphasize the reality, historical criticality accidents are presented in a table with major ones discussed to provide lessons-learned. Finally, standards, NRC guides and regulations, and DOE orders relating to criticality protection are presented

Our first result is the re-derivation of Mason-Skinner MHV amplitude by applying the S_{n-3} permutation symmetric KLT relations directly to MHV amplitude. Our second result is the equivalence proof of the newly discovered S_{n-2} permutation symmetric KLT relations and the well-known S_{n-3} permutation symmetric KLT relations. Although both formulas have been shown to be correct by BCFW recursion relations, our result is the first direct check using the regularized definition of the new formula.

    2016-01-01

    These lecture notes and example problems are based on a course given at the University of Cambridge in Part III of the Mathematical Tripos. Fluid dynamics is involved in a very wide range of astrophysical phenomena, such as the formation and internal dynamics of stars and giant planets, the workings of jets and accretion discs around stars and black holes, and the dynamics of the expanding Universe. Effects that can be important in astrophysical fluids include compressibility, self-gravitation and the dynamical influence of the magnetic field that is 'frozen in' to a highly conducting plasma. The basic models introduced and applied in this course are Newtonian gas dynamics and magnetohydrodynamics (MHD) for an ideal compressible fluid. The mathematical structure of the governing equations and the associated conservation laws are explored in some detail because of their importance for both analytical and numerical methods of solution, as well as for physical interpretation. Linear and nonlinear waves, includin...

    Full Text Available We aim at creating a note-taking device typically to be used in a classroom environment. Traditional methods of writing have limited speed and cannot keep up with speech. Writing with pen on paper requires us to look at the paper, which can reduce concentration on the ongoing discussion. Laptops are costly, power consuming and heavy for such a trivial task. Voice to text programs dont have the freedom of choosing the text to be included, and noise in the room can affect performance of such a program. Smart phones have a small keypad, which demands more user concentration. We have created a glove that one can wear and touch-type on any flat surface with minimal costs and power consumption. With ergonomics in mind, the glove has been designed to yield ten self fabricated switch button sensors to finally create a complete utility for simple and an inexpensive typing tool.

    Zannier, Umberto

    2014-01-01

    These lecture notes originate from a course delivered at the Scuola Normale in Pisa in 2006. Generally speaking, the prerequisites do not go beyond basic mathematical material and are accessible to many undergraduates. The contents mainly concern diophantine problems on affine curves, in practice describing the integer solutions of equations in two variables. This case historically suggested some major ideas for more general problems. Starting with linear and quadratic equations, the important connections with Diophantine Approximation are presented and Thue's celebrated results are proved in full detail. In later chapters more modern issues on heights of algebraic points are dealt with, and applied to a sharp quantitative treatment of the unit equation. The book also contains several Supplements, hinted exercises and an Appendix on recent work on heights.

  2. A note on neglect defaulting

    Directory of Open Access Journals (Sweden)

    Howard Margolis

    2008-04-01

    Full Text Available I introduce the notion of ``neglect defaulting,'' which labels the propensity to neglect possibilities which are ordinarily sensibly neglected. In familiar contexts we are well-tuned to recognize when to override the default. But outside the range of familiar experience --- here in the artificial context of puzzles --- these ordinarily benign defaults can make it difficult for even sophisticated subjects, such as readers of this note, to avoid responses which on reflection will be seen as obviously mistaken. A detail of particular importance is that, although subjects are easily prompted to take one step in the direction of reaching a sound response, the tendency to then neglect to consider that another step may be needed is remarkably strong. In each of the five examples the needed but usually neglected second step is quite trivial. Concluding remarks point to consequences for larger questions outside the range of familiar experience, in politics and other contexts out of scale with everyday experience.

    Full Text Available On the basis of ever-mounting evidence, amongst which is the “zone” problematic of the Zadar conference that occassioned these notes, it can be concluded that the spatial turn has insinuated itself as an all-pervading heuristic tool throughout the humanities and the social sciences. The extent to which space and spatiality have usurped the central stage in the various branches of reasearch can be gauged by admonishments that what we are witnessing is a new fundamentalism that has simply inverted the terms of the dualism of time and space (May and Thrift 2001: “Introduction”. According to Michael Dear the sway of space is manifested in multifold ways: in the ubiquity of spatial analysis in social theories and practices; in the explosion of publications devoted to the exploration of the interface of the social and the spatial; in the reintegration of human geography into various domains of knowledge; in the focus given to difference and the consequent diversification of theoretical and empirical practices; in a theoretically informed exploration of the relation between geographical knowledge and social action; and, finally, in the unprecedented proliferation of research agendas and publications pertaining to these isuuses (Dear 2001: 24. Two recent collections of papers are indicative of the ubiquity of spatial issues in scholarly work.

  16. Three notes about communism and anticommunism responsibility

    OpenAIRE

    Mihail Radu Solcan

    2014-01-01

    These are three loosely connected philosophical notes. The first note starts with a reflection on the idea that bad people (on top) defiled the communist ideal. The argument is that the descriptive phrase „the communist ideal“ cannot logically fulfil the uniqueness claim (and, in a coherent way, the universal claim) for its denotation. This leaves a large space for (good or bad) people’s responsibility. The second note makes a distinction between an anticommunism focused on a conspiracy theor...

  17. Linguistic analysis of suicide notes in Spain

    Full Text Available Background and Objectives: Text analysis software like "Linguistic Inquiry and Word Count" (LIWC has been used for the analysis of suicide notes and suicidal texts in English. This is the first analysis of suicide notes using this method in Spanish and, as far as we know, its first application to suicide notes in Europe. To compare the sociodemographic and forensic characteristics of a consecutive sample of suicide victims studying the differences between those who left suicidal note and those who did not. To study a sample of suicidal notes from Spain using LIWC, comparing it's linguistic features by gender, age and environment. Methods: 144 consecutive suicide cases were analyzed. 23 suicide notes obtained from this sample were processed using LIWC, the results were compared by gender, age and environment of the author. Results: People who left suicide notes were younger than non- writers; more frequently single, divorced or widowed and emotional troubles were reported as frequent triggers. Suicide notes written by women were significantly longer, had more emotional content, tentative expressions, denials, pronouns in first person plural and verbs in past and future tenses. Urban cases showed higher emotional expression and word complexity whereas rural cases showed a higher use of social words. Conclusions: Our study shows some differences between people who left suicide note and those who didn't and confirms the LIWC ability to detect differences in suicidal speech by gender and by the rural/ urban background of its authors.

  19. [The future of gastrointestinal therapeutic endoscopy: NOTES].

    Science.gov (United States)

    Dray, X; Marteau, P

    2009-01-01

    Natural orifice translumenal endoscopic surgery (NOTES) allows access into the peritoneal cavity with a flexible endoscope, through the wall of the digestive or urogenital tracts. NOTES can be combined to laparoscopic surgery in so-called techniques. In the absence of any incision of the abdominal wall, NOTES procedures provide perfect cosmetic results, with virtually no risk of parietal complications, and with decreased postoperative pain. NOTES could particularly benefit to overweight patients and to patients receiving intensive or palliative care. Most NOTES studies have been performed on animal models, with great interest for both transgastric and transpelvic approaches. Successful NOTES peritoneoscopy, hysterectomy, oophorectomy, tubal ligation, gastrojejunal anastomosis, cholecystectomy, splenectomy, nephrectomy, and abdominal-wall hernia repair have been described. In human studies, the transvaginal route is preferred. NOTES clinical research focuses on low-morbidity procedures, such as cholecystectomy, appendectomy, and peritoneoscopy. Indirect benefits are expected from this research, with possible technological innovations in the field of endoscopic instrumentation (including sutures, anastomosis, traction and triangulation). Overall, NOTES is believed to make evolve both interventional endoscopy and minimally invasive surgery. PMID:19683406

    In 2010, the LHC experiment produced 7 TeV and heavy-ions collisions continually, generating a huge amount of data, which was analyzed and reported throughout several performed studies. Since then, physicists are bringing out papers and conference notes announcing results and achievements. During 2010, 37 papers and 102 conference notes were published and until April 2012 there are already 275 papers and 371 conference notes in preparation. This paper presents the ATLAS Analysis Papers and ATLAS Analysis Conference Notes systems, developed to monitor the entire publication procedure up to the final submission and to promote the communication among the collaboration members. The software supports the paper elaboration process, tracking the analysis results status and improvement of the paper initial version, presenting a step-by-step procedure overview and promoting communication among collaborators. Along with the increasing flow of papers and conference notes, one of the issues is the way to guarantee that all members who participate in the analysis studies are aware of not only the discussion deadlines but also of the publication process, which involves 17 steps, split in 3 different phases for papers and 10 steps in 1 phase for conference notes. By sending notifications based on predefined rules the systems inform members to approve each step and provide further information such as the approval conditions and the documents in which the publication is based on. Through the software it is also possible to manage dates and members of the editorial team. The data processing is performed by using the Glance System, the main data retrieval platform used for ATLAS information management.

  1. A Note on Encodings of Phylogenetic Networks of Bounded Level

    CERN Document Server

    Gambette, Philippe

    2009-01-01

    Driven by the need for better models that allow one to shed light into the question how life's diversity has evolved, phylogenetic networks have now joined phylogenetic trees in the center of phylogenetics research. Like phylogenetic trees, such networks canonically induce collections of phylogenetic trees, clusters, and triplets, respectively. Thus it is not surprising that many network approaches aim to reconstruct a phylogenetic network from such collections. Related to the well-studied perfect phylogeny problem, the following question is of fundamental importance in this context: When does one of the above collections encode (i.e. uniquely describe) the network that induces it? In this note, we present a complete answer to this question for the special case of a level-1 (phylogenetic) network by characterizing those level-1 networks for which an encoding in terms of one (or equivalently all) of the above collections exists. Given that this type of network forms the first layer of the rich hierarchy of lev...

    As Drucker notes in The Atlantic Monthly (1994:53), the 21st century will be one of transformations and challenges. Nurse educators will need to think through the purposes, values, and content of educational programs and lifelong learning opportunities. Nurse educators as knowledge workers must prepare to meet challenges by developing nursing learning centers for future needs. Whereas a bold vision of the future, concrete plans that a customer driven, and monitoring for improvement are important, the nurse educator as manager/dean/director for the learning center and faculty teaching here will be key to facilitating nursings' transformation into the information age.

  1. Note on the Theory of Perfect Numbers

    OpenAIRE

    Carella, N. A.

    2011-01-01

    A perfect number is a number whose divisors add up to twice the number itself. The existence of odd perfect numbers is a millennia-old unsolved problem. This note proposes a proof of the nonexistence of odd perfect numbers. More generally, the same analysis seems to generalize to a proof of the nonexistence of odd multiperfect numbers.

  2. Three notes about communism and anticommunism responsibility

    Directory of Open Access Journals (Sweden)

    Mihail Radu Solcan

    2014-12-01

    Full Text Available These are three loosely connected philosophical notes. The first note starts with a reflection on the idea that bad people (on top defiled the communist ideal. The argument is that the descriptive phrase „the communist ideal“ cannot logically fulfil the uniqueness claim (and, in a coherent way, the universal claim for its denotation. This leaves a large space for (good or bad people’s responsibility. The second note makes a distinction between an anticommunism focused on a conspiracy theory and an anticommunism focused on an institutional criticism of communism. It argues that this distinction casts doubts on the usual division in political analysis between left and right. The third text notes the practical impossibility of a complete legal or ethical trial of communism according to usual standards of justice. The only solution would be a Raskolnikov-like awakening in the consciousness of the potential defendants. This situation, at least in Romania, seems to solidify a right inflamed by bold rhetoric and a left unable to look critically at the past.

  15. The ALARA (as low as reasonably achievable) concept in pediatric interventional and fluoroscopic imaging: striving to keep radiation doses as low as possible during fluoroscopy of pediatric patients - a white paper executive summary

    Energy Technology Data Exchange (ETDEWEB)

    Strauss, Keith J. [Children' s Hospital, Department of Radiology, Boston, MA (United States); Kaste, Sue C. [St. Jude Children' s Research Hospital, Division of Diagnostic Imaging, Memphis, TN (United States)

    2006-09-15

    ALARA represents a practice mandate adhering to the principle of keeping radiation doses to patients and personnel As Low As Reasonably Achievable. This concept is strongly endorsed by the Society for Pediatric Radiology, particularly in the use of procedures and modalities involving higher radiation doses such as CT and fluoroscopic examinations of pediatric patients. There is no doubt that medical imaging, which has undergone tremendous technological advances in recent decades, is integral to patient care. However, these technological advances generally precede the knowledge of end-users concerning the optimal use and correct operation of the resulting imaging equipment, and such knowledge is essential to minimizing potential risks to the patients. Current imaging methods must be optimized for radiation dose reduction in pediatric patients who might be as much as ten times more radiosensitive than adults. Unlike straightforward radiographic examinations, radiation dose to the patient during fluoroscopy is dependent on the operator's training, experience with the fluoroscope, and efficiency in completing a diagnostic study. The range of pediatric radiation doses from fluoroscopy is wide because this examination is performed not only by pediatric radiologists but also by general radiologists who occasionally care for children, interventional cardiologists, gastroenterologists, urologists and others. Thus, a venue where multidisciplinary interaction by this variety of operators can occur serves to improve pediatric patient care.

    2016-07-01

    The advent of the electronic medical record (EMR) combined with an expansion of information required by medicolegal and billing departments has transformed the progress note from a succinct note into an often unwieldy data-dump unable to concisely convey the physician's medical reasoning. We describe a new note format--CAPS, which stands for concern, assessment, plan, and supporting data--to streamline the communication of the patient's problem, the practitioner's assessment and plan, and the medical reasoning to support the plan.

  5. Molecular gastronomy is a scientific discipline, and note by note cuisine is the next culinary trend

    Directory of Open Access Journals (Sweden)

    This Hervé

    2013-01-01

    Full Text Available Abstract For the past two decades, there has been much confusion about molecular gastronomy. This confusion has arisen because people ignore that the word gastronomy does not mean cuisine, it means knowledge about food. Similar to ‘molecular biology’, molecular gastronomy is a scientific discipline that looks for the mechanisms of phenomena occurring during dish preparation and consumption. As with any other scientific discipline, it can have many applications. One of the first was ‘molecular cuisine’ but since 1994, ‘note by note cuisine’ has also been promoted. The latter involves preparing dishes using pure compounds, or more practically mixture of compounds obtained by fractioning plant or animal tissues, instead of using these tissues themselves. Note by note cuisine raises issues in various fields: science, technology, nutrition, physiology, toxicology and politics.

  7. The ancient Chinese notes on hydrogeology

    Science.gov (United States)

    Zhou, Yu; Zwahlen, François; Wang, Yanxin

    2011-08-01

    The ancient Chinese notes on hydrogeology are summarized and interpreted, along with records of some related matters, like groundwater exploration and utilization, karst springs, water circulation, water conservation and saline-land transformation, mine drainage, and environmental hydrogeology. The report focuses only on the earliest recorded notes, mostly up until the Han Dynasty (206 BC - AD 25). Besides the references cited, the discussion in this report is based mainly on archaeological material, the preserved written classic literature, and some assumptions and/or conclusions that have been handed down in legends to later ages. Although most material relates to ancient China, the lessons learned may have practical significance worldwide. Compared to other contemporary parts of the world, ancient China, without doubt, took the lead in the field of groundwater hydrology. The great achievements and experience of the Chinese ancestors should provide motivation and inspiration for hydrogeologists to carry out their scientific research and exploration passionately and actively.

    2006-01-01

    This note gives a short introduction of how to make socio-economic evaluations in connection with the teaching at the Centre for Traffic and Transport (CTT). It is not a manual for making socio-economic calculations in transport infrastructure projects – in this context we refer to the guidelines...... for socio-economic calculations within the transportation area (Ministry of Traffic, 2003). The note also explains the theory of socio-economic calculations – reference is here made to ”Road Infrastructure Planning – a Decision-oriented approach” (Leleur, 2000). Socio-economic evaluations of...... infrastructure projects are common and can be made at different levels of detail depending on the type of project and the decision making phase. A common feature of the different levels of detail of the socio-economic analysis is that the planned project(s) is compared with a basic; the basic alternative or a...

  11. Writing and Music: Album Liner Notes

    Directory of Open Access Journals (Sweden)

    Dean Leonard Biron

    2011-01-01

    Full Text Available A deceptive aspect of the ‘writing about music is like dancing about architecture’ cliché is the function of the preposition ‘about’. Literature and music, dance and architecture, painting and film – all are discrete aesthetic forms that nonetheless simultaneously feed off and provide nourishment for each other as part of art’s perpetual drive toward diversity and innovation. Nowhere is the aptness of the association between writing and music more obvious than in the phenomenon of album liner notes. Rather than merely an attempt at describing or translating musical experience, liner notes contribute to the dialogue between composer and listener and are a significant part of the culture of contemporary music.

  12. Flatland an edition with notes and commentary

    CERN Document Server

    Abbott, Edwin A; Banchoff, Thomas F

    2010-01-01

    Flatland, Edwin Abbott Abbott's story of a two-dimensional universe, as told by one of its inhabitants who is introduced to the mysteries of three-dimensional space, has enjoyed an enduring popularity from the time of its publication in 1884. This fully annotated edition enables the modern-day reader to understand and appreciate the many "dimensions" of this classic satire. Mathematical notes and illustrations enhance the usefulness of Flatland as an elementary introduction to higher-dimensional geometry. Historical notes show connections to late-Victorian England and to classical Greece. Citations from Abbott's other writings as well as the works of Plato and Aristotle serve to interpret the text. Commentary on language and literary style includes numerous definitions of obscure words. An appendix gives a comprehensive account of the life and work of Flatland's remarkable author.

This procedure can be used to reduce the number of candidate static layouts to be examined. An important feature of our procedure is that a feasible dynamic solution is not required in order to apply it. The effectiveness of this procedure depends on the relative magnitude of the shifting costs.

    2006-01-01

    This Trade and Integration Sector Note addresses a few different factors for trade in Chile: export diversification, trade and regional disparities, preferential agreements, trade and transport costs. The final section looks beyond the conventional tariff and non tariff-barriers to trade, and focuses on the role of transport costs. Given Chile's low tariff and non-tariff barriers and its network of trade agreements, the reduction of non-conventional trade costs are bound to offer the best ret...

  11. Energy and greenhouse effect. Twelve short notes

    International Nuclear Information System (INIS)

    The author proposes twelve brief notes aimed at discussing the reduction of fossil energy consumption in order to reduce CO2 emissions and to improve the French energy supply security, without any useless expense. These notes address the reason for energy savings, the cost and price of a CO2 ton, the issue of thermal regulation for buildings (it's not in compliance with the law, and results in higher expenses and increased CO2 emissions), the introduction of a carbon tax to incite investments for energy saving, the status and health of the CO2 European market, the support of actions aimed at reducing fossil energy consumption, the fact that bio-heat is ten times more efficient than bio-fuel and that therefore car holders should finance bio-heat, the development of hybrid uses of energy to avoid the difficulty of energy storage, the reduction of CO2 emissions at low cost (by consuming as much renewable energy as nuclear energy but without wind or photovoltaic energy), the cost of less CO2, less fossil energy and less nuclear, and the interest of France to act on its own to reduce CO2 emissions. The author proposes a brief synthesis of these notes and some proposals regarding thermal regulation for buildings, taxes, the European CO2 market, the forest biomass, electricity production, and the European and word dimensions of these issues

  14. Can A Smartphone Replace The Operative Note?

    Science.gov (United States)

    Featherall, Joseph; Oak, Sameer; Vega, Jose F.; Strnad, Greg; Spindler, Kurt P.

    2016-01-01

    Objectives: A large portion of the body of orthopedic surgical research is conducted retrospectively, using the operative note as a main data source. Operative notes tend to infrequently report quantitative data, significantly limiting the precision with which research questions can be assessed (Scherer et al., 2003). Large scale surgical outcomes studies have identified specific surgical parameters as valid predictors of key surgical outcomes (Kaeding, Pedroza, Reinke, Huston, & Spindler, 2015). Thus, it is now feasible to develop a data capture system that collects more accurate, robust surgical data quickly and with lower cost than operative note dictation. The objectives of this study are as follows: 1. Develop a provider-friendly, evidence-based, data capture system for lower limb orthopedic surgeries.2. Assess the performance of the data capture system on the dimensions of agreement with operative note and implant log, consistency of data quality, and speed of provider input. Methods: A multidisciplinary team including administration, orthopedic surgery staff, and software development was assembled for the design of the surgical database. The database was developed in Redcap and user interfaces were created for Android and IOS operating systems. Branching logic was created to streamline provider data input. All data input was created with discrete fields. Cleveland Clinic owned I-Phones were used for surgeon data input. All surgeons at Cleveland Clinic Sports Health were included in the dataset. One hundred cases were randomly selected from the first four months of data collection (February- June 2015). Cases were limited to those undergoing ACL repair, meniscal repair, or both. Duplicate data on these 100 cases was collected via chart review. These two datasets were compared. Cohen’s Kappa statistic was used to assess agreement. Results: Table 1 shows the Kappa statistic and 95% confidence interval for agreement between the database and the chart review

    Directory of Open Access Journals (Sweden)

    K. Michael Hays

    2014-07-01

    Full Text Available These notes are offered as a sketch of interpretive method. I suggest that the writing of architectural history is, or should be, a deeply theoretical sort of symptomatology – an account of how the very forms and experiences of architecture both construct and repress the absent thing we call the social, and are its most material symbolizations. Such an account benefits from an idea and a practice of narrative. Narrative is an ideological production that avoids any copy theories of representation even as it insists on the real, material forms and events that are its subject matter.

  18. The Saving to Income Ratio: A Note

    OpenAIRE

    Lester, Laurence H.

    1996-01-01

    It has been suggested that, whilst in the late 1960s to early 1970s saving rates were quite high, since then there has been a gradual and persistent reduction in the saving to income ratio (S/Y) - thus indicating a substantial change in behaviour. This note considers the ratio of private saving to an adjusted measure of income (S/Y*) finding evidence to suggest that whilst the S/Y ratio is a nonstationary random walk, the ratio S/Y* is stationary (random fluctuations about its mean). This 'me...

    Science.gov (United States)

    Stahl, K

    1983-11-01

    "The purpose of this note is to demonstrate in a simple model that an individual's migration from a small town to a large city may be rationalized purely by a consumption motive, rather than the motive of obtaining a higher income. More specifically, it is shown that in a large city an individual may derive a higher utility from spending a given amount of income than in a small town." A formal model is first developed that includes the principal forces at work and is then illustrated using a graphic example. The theoretical and empirical issues raised are considered in the concluding section. PMID:12312600

    These pedagogical lecture notes address to the students in theoretical physics for helping them to understand the mechanisms of the linear operators defined on finite-dimensional vector spaces equipped with definite or indefinite inner products. The importance of the Dirac conjugation is pointed out presenting its general theory and a version of the Riesz theorem for the indefinite inner product spaces, based on the Dirac-Riesz map that combines the action of the Riesz map with that of the metric operator. The matrix representations of the linear operators on vector spaces with definite or indefinite inner products is also presented.

  6. A note on oblique water entry

    KAUST Repository

    Moore, M. R.

    2012-10-02

    A minor error in Howison et al. (J. Eng. Math. 48:321-337, 2004) obscured the fact that the points at which the free surface turns over in the solution of the Wagner model for the oblique impact of a two-dimensional body are directly related to the turnover points in the equivalent normal impact problem. This note corrects some of the earlier results given in Howison et al. (J. Eng. Math. 48:321-337, 2004) and discusses the implications for the applicability of the Wagner model. © 2012 Springer Science+Business Media B.V.

  8. A Note on Teaching Binomial Confidence Intervals

    OpenAIRE

    Santner, Thomas J.

    1997-01-01

    For constructing confidence intervals for a binomial proportion $p$, Simon (1996, Teaching Statistics) advocates teaching one of two large-sample alternatives to the usual $z$-intervals $\\hat{p} \\pm 1.96 \\times S.E(\\hat{p})$ where $S.E.(\\hat{p}) = \\sqrt{ \\hat{p} \\times (1 - \\hat{p})/n}$. His recommendation is based on the comparison of the closeness of the achieved coverage of each system of intervals to their nominal level. This teaching note shows that a different alternative to $z$-interv...

  9. A Note On Higher Order Grammar

    CERN Document Server

    Gluzberg, Victor

    2009-01-01

    Both syntax-phonology and syntax-semantics interfaces in Higher Order Grammar (HOG) are expressed as axiomatic theories in higher-order logic (HOL), i.e. a language is defined entirely in terms of provability in the single logical system. An important implication of this elegant architecture is that the meaning of a valid expression turns out to be represented not by a single, nor even by a few "discrete" terms (in case of ambiguity), but by a "continuous" set of logically equivalent terms. The note is devoted to precise formulation and proof of this observation.

  10. Notes on human error analysis and prediction

    International Nuclear Information System (INIS)

    The notes comprise an introductory discussion of the role of human error analysis and prediction in industrial risk analysis. Following this introduction, different classes of human errors and role in industrial systems are mentioned. Problems related to the prediction of human behaviour in reliability and safety analysis are formulated and ''criteria for analyzability'' which must be met by industrial systems so that a systematic analysis can be performed are suggested. The appendices contain illustrative case stories and a review of human error reports for the task of equipment calibration and testing as found in the US Licensee Event Reports. (author)

  11. Lecture notes on 2-dimensional defect TQFT

    CERN Document Server

    Carqueville, Nils

    2016-01-01

    These notes offer an introduction to the functorial and algebraic description of 2-dimensional topological quantum field theories `with defects', assuming only superficial familiarity with closed TQFTs in terms of commutative Frobenius algebras. The generalisation of this relation is a construction of pivotal 2-categories from defect TQFTs. We review this construction in detail, flanked by a range of examples. Furthermore we explain how open/closed TQFTs are equivalent to Calabi-Yau categories and the Cardy condition, and how to extract such data from pivotal 2-categories.

  12. A Note on Markov Normalized Magnetic Eigenmaps

    CERN Document Server

    Cloninger, Alexander

    2016-01-01

    We note that building a magnetic Laplacian from the Markov transition matrix, rather than the graph adjacency matrix, yields several benefits for the magnetic eigenmaps algorithm. The two largest benefits are that the embedding becomes more stable as a function of the rotation parameter g, and the principal eigenvector of the magnetic Laplacian now converges to the page rank of the network as a function of diffusion time. We show empirically that this normalization improves the phase and real/imaginary embeddings of the low-frequency eigenvectors of the magnetic Laplacian.

  17. EVALUATION OF STUDENT'S NOTES IN A BLENDED LEARNING COURSE

    Directory of Open Access Journals (Sweden)

    Minoru Nakayama

    2011-01-01

    Full Text Available Student’s notes are evaluated to trace their learning process in a blended learning course, and the factors affecting the quality of these notes are discussed. As individual note-taking performance may be based on student’s characteristics, these contributions are also examined. Some factors about per-sonality and the learning experience are sig-nificant, and positively affect the grades given to notes. Lexical features of notes tak-en were extracted using a text analysis tech-nique, and these features were compared with the grades given. The good note-takers constantly recorded terms independently of the number of terms which was presented during the class. Conceptual mapping of the contents of notes was conducted, and it sug-gests that the deviation in the features of notes can be explained by the number of terms in a lesson.

  18. How college science students engage in note-taking strategies

    Science.gov (United States)

    Bonner, Janice M.; Holliday, William G.

    2006-10-01

    A composite theory of college science student note-taking strategies was derived from a periodic series of five interviews with 23 students and with other variables, including original and final versions of notes analyzed during a semester-long genetics course. This evolving composite theory was later compared with Van Meter, Yokoi, and Pressley's (Journal of Educational Psychology, 86, 323-338, 1994) corresponding composite college students' theory of note-taking. Students' notes in this long-term study were also compared with a standard of adequate note-taking established by experts. Analyses detected many similarities between the two composite theories. Analyses also provided evidence of inadequate note-taking strategies, inconsistencies between what students claimed and evidently did with their notes, and weak self-regulating learning strategies. Recommendations included prompting students during class on how to take notes.

Bridging the gap between BioTM researchers and biologists' needs is crucial to solve real-world problems and promote further research. We present @Note, a platform for BioTM that aims at the effective translation of the advances between three distinct classes of users: biologists, text miners and software developers. Its main functional contributions are the ability to process abstracts and full-texts; an information retrieval module enabling PubMed search and journal crawling; a pre-processing module with PDF-to-text conversion, tokenisation and stopword removal; a semantic annotation schema; a lexicon-based annotator; a user-friendly annotation view that allows to correct annotations and a Text Mining Module supporting dataset preparation and algorithm evaluation. @Note improves the interoperability, modularity and flexibility when integrating in-home and open-source third-party components. Its component-based architecture allows the rapid development of new applications, emphasizing the principles of transparency and simplicity of use. Although it is still on-going, it has already allowed the development of applications that are currently being used. PMID:19393341

    Science.gov (United States)

    Rolfe, John

    1990-04-01

    The security of bank notes against counterfeiting can be improved by the incorporation of optically variable devices (OVDs), which change their appearance when the note is viewed in different directions. Three types of OVD; holograms, multiple diffraction gratings, and thin film interference filters will be compared in relation to the special requirements unique to bank notes; security, visibility and durability. The Bank of Canada has recently issued $50 bank notes bearing a five-layer thin film interference filter. The tests which led to this particular form of OVD will be described, together with methods of deposition, quality control, and application to sheets of bank notes.

  8. Leveraging Call Center Logs for Customer Behavior Prediction

    Science.gov (United States)

    Parvathy, Anju G.; Vasudevan, Bintu G.; Kumar, Abhishek; Balakrishnan, Rajesh

    Most major businesses use business process outsourcing for performing a process or a part of a process including financial services like mortgage processing, loan origination, finance and accounting and transaction processing. Call centers are used for the purpose of receiving and transmitting a large volume of requests through outbound and inbound calls to customers on behalf of a business. In this paper we deal specifically with the call centers notes from banks. Banks as financial institutions provide loans to non-financial businesses and individuals. Their call centers act as the nuclei of their client service operations and log the transactions between the customer and the bank. This crucial conversation or information can be exploited for predicting a customer’s behavior which will in turn help these businesses to decide on the next action to be taken. Thus the banks save considerable time and effort in tracking delinquent customers to ensure minimum subsequent defaulters. Majority of the time the call center notes are very concise and brief and often the notes are misspelled and use many domain specific acronyms. In this paper we introduce a novel domain specific spelling correction algorithm which corrects the misspelled words in the call center logs to meaningful ones. We also discuss a procedure that builds the behavioral history sequences for the customers by categorizing the logs into one of the predefined behavioral states. We then describe a pattern based predictive algorithm that uses temporal behavioral patterns mined from these sequences to predict the customer’s next behavioral state.

  9. A note on "communicating between information systems"

    CERN Document Server

    Zhu, Ping

    2010-01-01

    This note is an amendment to a paper by Wang et al. [C. Wang, C. Wu, D. Chen, Q. Hu, and C. Wu, Communicating between information systems, Information Sciences 178 (2008) 3228-3239]. To study the communication between two information systems, Wang et al. proposed two concepts of type-1 and type-2 consistent functions. Some good properties of consistent functions and induced relation mappings have been investigated there. In this paper, we provide an improvement of the aforementioned work by disclosing the symmetric relationship between type-1 and type-2 consistent functions. We present more properties of consistent functions and induced relation mappings and correct several deficient assertions in the original work. In particular, we unify and extend type-1 and type-2 consistent functions into the so-called neighborhood-consistent functions. This provides a convenient means for studying the communication between information systems based on various neighborhoods.

  10. Galaxy Bulges and Elliptical Galaxies - Lecture Notes

    2012-01-01

    Our knowledge on the central components of disk galaxies has grown substantially in the past few decades, particularly so in the last. This frantic activity and the complexity of the subject promote confusion in the community. In these notes, I discuss the concept of galactic bulge and its different flavors. I also address fundamental scaling relations and the bulge-elliptical galaxy connection, their central black holes and formation models. In particular, I aim at conveying three important notions: (i): box/peanuts are just the inner parts of bars; (ii): the physical reality of two different families of bulges is evident; and (iii): at the high mass end, at least, classical bulges are not just scaled down ellipticals surrounded by disks.

  11. Notes on parafermionic QFT's with boundary interaction

    CERN Document Server

    Lukyanov, S L

    2006-01-01

    The main result of these notes is an analytical expression for the partition function of the circular brane model for arbitrary values of the topological angle. The model has important applications in condensed matter physics. It is related to the dissipative rotator (Ambegaokar-Eckern-Schon) model and describes a ``weakly blocked'' quantum dot with an infinite number of tunneling channels under a finite gate voltage bias. A numerical check of the analytical solution by means of Monte Carlo simulations has been performed recently. To derive the main result we study the so-called boundary parafermionic sine-Gordon model. The latter is of certain interest to condensed matter applications, namely as a toy model for a point junction in the multichannel quantum wire.

    International Nuclear Information System (INIS)

    These are lecture notes that cover a selection of topics, some of them under current research, in accelerator physics. I try to derive the results from first principles, although the students are assumed to have an introductory knowledge of the basics. The topics covered are: (1) Panofsky-Wenzel and Planar Wake Theorems; (2) Echo Effect; (3) Crystalline Beam; (4) Fast Ion Instability; (5) Lawson-Woodward Theorem and Laser Acceleration in Free Space; (6) Spin Dynamics and Siberian Snakes; (7) Symplectic Approximation of Maps; (8) Truncated Power Series Algebra; and (9) Lie Algebra Technique for nonlinear Dynamics. The purpose of these lectures is not to elaborate, but to prepare the students so that they can do their own research. Each topic can be read independently of the others

    In this note, we have addressed various issues on zero temperature holographic superfluids. First, inspired by our numerical evidence for the equality between the superfluid density and particle density, we provide an elegant analytic proof for this equality by a boost trick. Second, using not only the frequency domain analysis but also the time domain analysis from numerical relativity, we identify the hydrodynamic normal modes and calculate out the sound speed, which is shown to increase with the chemical potential and saturate to the value predicted by the conformal field theory in the large chemical potential limit. Third, the generic non-thermalization is demonstrated by the fully non-linear time evolution from a non-equilibrium state for our zero temperature holographic superfluid. Furthermore, a conserved Noether charge is proposed in support of this behavior.

    Full Text Available Longtemps absent dans les sciences sociales françaises, le terme "postcolonial" apparaît de plus en plus fréquemment dans les publications et programmes de rencontres, sous l'impulsion des débats autour de l'héritage de la colonisation et des "indigènes de la République". Dans ce contexte, cette note présente les principaux traits qui fondent des postcolonial studies telles qu'elles se sont développées dans le monde anglo-saxon depuis une vingtaine d'années. Cette mise au point, à l'usage des géographes entre autres, vise à clarifier les échanges en montrant le décalage entre le post-colonial français et les postcolonial studies.Long ignored by French social sciences, the term "postcolonial" has recently become popular in academic literature and meetings, in relation to the political debate about colonial legacy and 2nd and 3rd immigrants generations (the so-called "indigènes de la République". Yet, although the term is the same ("postcolonial", the meaning it is usually given in France by those who qualify their work as such is quite different from the one it has in the anglo world. In this context, this note aims at clarifying the situation for French geographers and others by presenting briefly some of the main aspects of postcolonial theory.

    In toroidal fusion devices it is relatively easy that electrons achieve relativistic velocities, so to simulate runaway electrons and other high energy phenomena a nonrelativistic guiding center formalism is not sufficient. Relativistic guiding center equations including flute mode time dependent field perturbations are derived. The same variables as used in a previous nonrelativistic guiding center code are adopted, so that a straightforward modifications of those equations can produce a relativistic version.

    Ioannou, Maria; Debowska, Agata

    2014-11-01

    The present study examined genuine and simulated suicide notes aiming to identify the measures of content that best differentiate between the two. Thirty-three genuine and thirty-three simulated suicide notes were content-analysed and data subjected to smallest space analysis (SSA), a Multidimensional Scaling Procedure. The core of all suicide notes was discovered to be constructed with the use of three variables: expressions of love, positive construction of partner and apologies. Furthermore, four different genuine suicide note themes ('planned escape', 'negative affect and self-mitigation', 'positive affect and failed relationship', 'lack of self-acceptance') and three simulated suicide note themes ('escape', 'positive affect and self-blame', 'purposeless life') were identified revealing that authentic suicide note themes were more internally consistent and clearer to interpret.

    Most educators consider note-taking a critical component of formal classroom learning. Advancements in technology such as tablet computers, mobile applications, and recorded lectures are altering classroom dynamics and affecting the way students compose and review class notes. These tools may improve a student's ability to take notes, but they also may hinder learning. In an era of dynamic technology developments, it is important for educators to routinely examine and evaluate influences on formal and informal learning environments. This paper discusses key background literature on student note-taking, identifies recent trends and potential implications of mobile technologies on classroom note-taking and student learning, and discusses future directions for note-taking in the context of digitally enabled lifelong learning.

  14. Notes on Mayer expansions and matrix models

    International Nuclear Information System (INIS)

    Mayer cluster expansion is an important tool in statistical physics to evaluate grand canonical partition functions. It has recently been applied to the Nekrasov instanton partition function of N=2 4d gauge theories. The associated canonical model involves coupled integrations that take the form of a generalized matrix model. It can be studied with the standard techniques of matrix models, in particular collective field theory and loop equations. In the first part of these notes, we explain how the results of collective field theory can be derived from the cluster expansion. The equalities between free energies at first orders is explained by the discrete Laplace transform relating canonical and grand canonical models. In a second part, we study the canonical loop equations and associate them with similar relations on the grand canonical side. It leads to relate the multi-point densities, fundamental objects of the matrix model, to the generating functions of multi-rooted clusters. Finally, a method is proposed to derive loop equations directly on the grand canonical model

    2015-01-01

    This is a set of notes which reviews and addresses issues in the SL(2,R) conformal field theory, while working primarily in a basis of vertex operators of definite weight under the affine algebra. Following a review of the H3 coset model and the spectrum of the SL(2,R) CFT, derivations are given for the selection rules and the reduction of descendant to primary correlators involving arbitrary spectral flowed modules. Together with a description of the equivalence of correlation functions of fixed total spectral flow, this leads to an enumeration of the minimal set of three-point amplitudes required to determine the fusion rules. The corresponding fusion rules for elements of the spectrum are compared to those which arise through analytic continuation of the OPE of primary fields in the H3 model, and the apparent failure of the closure of the associated SL(2,R) OPE is described in detail. A discussion of the consistency of the respective fusion rules with the conjectured structure of equivalent factorizations ...

  16. Note on the Khaneja Glaser Decomposition

    CERN Document Server

    Bullock, S S

    2004-01-01

    Recently, Vatan and Williams utilize a matrix decomposition of SU(2^n) introduced by Khaneja and Glaser to produce CNOT-efficient circuits for arbitrary three-qubit unitary evolutions. In this note, we place the Khaneja Glaser Decomposition (KGD) in context as a SU(2^n)=KAK decomposition by proving that its Cartan involution is type AIII, given n is greater than 2. The standard type AIII involution produces the Cosine-Sine Decomposition (CSD), a well-known decomposition in numerical linear algebra which may be computed using mature, stable algorithms. In the course of our proof that the KGD is type AIII, we further establish the following. Khaneja and Glaser allow for a particular degree of freedom, namely the choice of a commutative algebra a, in their construction. Let SWAP denote a swap between qubits 1 and n. Then for appropriate choice of a, the KGD by (SWAP v SWAP)=k1 a k2 may be recovered from a CSD by v = (SWAP k1 SWAP) (SWAP a SWAP) (SWAP k2 SWAP).

    This book presents, in his own words, the life of Hugo Steinhaus (1887–1972), noted Polish mathematician of Jewish background, educator, and mathematical popularizer. A student of Hilbert, a pioneer of the foundations of probability and game theory, and a contributor to the development of functional analysis, he was one of those instrumental to the extraordinary flowering of Polish mathematics before and after World War I. In particular, it was he who “discovered” the great Stefan Banach. Exhibiting his great integrity and wit, Steinhaus’s personal story of the turbulent times he survived – including two world wars and life postwar under the Soviet heel – cannot but be of consuming interest. His recounting of the fearful years spent evading Nazi terror is especially moving. The steadfast honesty and natural dignity he maintained while pursuing a life of demanding scientific and intellectual enquiry in the face of encroaching calamity and chaos show him to be truly a mathematician for all seasons. ...

    Full Text Available The exhibition entitled "Forme per il David", which took place at the Accademia of Florence between 2004 and 2005, and the analysis of the spectators’ reactions are the occasion for a series of reflections on psychological dynamics of the reception of art. After some preliminary notes on methodological issues of interdisciplinarity and on the way of empirical research about the attitude of the public in museums, the article (even taking into account the reactions of the audience in front of Michelangelo's David focuses on the erotic-instinctual elements in the enjoyment of arts, and offers some criticism about the use of the sublimation’s concept. It then speaks about the role and "degrees" of the “Uncanny” and about the dynamics of identification processes in the study of art fruition. It also emphasizes the importance of the "context" of use as a preliminary to the understanding of its mechanisms. The last section is devoted to the problem of emotion considered from the point of view of psychology, art and aesthetics.

  19. Note onset deviations as musical piece signatures.

    Directory of Open Access Journals (Sweden)

    Joan Serrà

    Full Text Available A competent interpretation of a musical composition presents several non-explicit departures from the written score. Timing variations are perhaps the most important ones: they are fundamental for expressive performance and a key ingredient for conferring a human-like quality to machine-based music renditions. However, the nature of such variations is still an open research question, with diverse theories that indicate a multi-dimensional phenomenon. In the present study, we consider event-shift timing variations and show that sequences of note onset deviations are robust and reliable predictors of the musical piece being played, irrespective of the performer. In fact, our results suggest that only a few consecutive onset deviations are already enough to identify a musical composition with statistically significant accuracy. We consider a mid-size collection of commercial recordings of classical guitar pieces and follow a quantitative approach based on the combination of standard statistical tools and machine learning techniques with the semi-automatic estimation of onset deviations. Besides the reported results, we believe that the considered materials and the methodology followed widen the testing ground for studying musical timing and could open new perspectives in related research fields.

  14. Relative Lyapunov Center Bifurcations

    DEFF Research Database (Denmark)

    Wulff, Claudia; Schilder, Frank

    2014-01-01

    Relative equilibria (REs) and relative periodic orbits (RPOs) are ubiquitous in symmetric Hamiltonian systems and occur, for example, in celestial mechanics, molecular dynamics, and rigid body motion. REs are equilibria, and RPOs are periodic orbits of the symmetry reduced system. Relative Lyapunov...... center bifurcations are bifurcations of RPOs from REs corresponding to Lyapunov center bifurcations of the symmetry reduced dynamics. In this paper we first prove a relative Lyapunov center theorem by combining recent results on the persistence of RPOs in Hamiltonian systems with a symmetric Lyapunov...... center theorem of Montaldi, Roberts, and Stewart. We then develop numerical methods for the detection of relative Lyapunov center bifurcations along branches of RPOs and for their computation. We apply our methods to Lagrangian REs of the N-body problem....

  15. Prophylactic Antibiotic Management of Surgical Patients Noted as "Allergic" to Penicillin at Two Academic Hospitals.

    Epstein, Richard H; Jacques, Paul St; Wanderer, Jonathan P; Bombulie, Mark R; Agarwalla, Niraj

    2016-05-01

    We studied prophylactic antibiotics administered at 2 academic medical centers during a 6-year period where a cephalosporin was indicated but an "allergy" to penicillin was noted. Another drug (typically vancomycin or clindamycin) was substituted approximately 80% of the time; this occurred frequently even when symptoms unrelated to acute hypersensitivity were listed. In >50% of cases, the reaction was either omitted or vague (e.g., simply "rash"). Given the estimated 1% cross-reactivity between penicillins and cephalosporins with similar R1 side chains, many of these patients could have received either the prescribed cephalosporin or another cephalosporin with a different R1 side chain.

  16. Virtual radiation fields for ALARA determination

    International Nuclear Information System (INIS)

    As computing power has increased, so too has the ability to model and simulate complex systems and processes. In addition, virtual reality technology has made it possible to visualize and understand many complex scientific and engineering problems. For this reason, a virtual dosimetry program called Virtual Radiation Fields (VRF) is developed to model radiation dose rate and cumulative dose to a receptor operating in a virtual radiation environment. With the design and testing of many facilities and products taking place in the virtual world, this program facilitates the concurrent consideration of radiological concerns during the design process. Three-dimensional (3D) graphical presentation of the radiation environment is made possible through the use of IGRIP, a graphical modeling program developed by Deneb Robotics, Inc. The VRF simulation program was designed to model and display a virtual dosimeter. As a demonstration of the program's capability, the Hanford tank, C-106, was modeled to predict radiation doses to robotic equipment used to remove radioactive waste from the tank. To validate VRF dose predictions, comparison was made with reported values for tank C-106, which showed agreement to within 0.5%. Graphical information is presented regarding the 3D dose rate variation inside the tank. Cumulative dose predictions were made for the cleanup operations of tank C-106. A four-dimensional dose rate map generated by VRF was used to model the dose rate not only in 3D space but also as a function of the amount of waste remaining in the tank. This allowed VRF to predict dose rate at any stage in the waste removal process for an accurate simulation of the radiological conditions throughout the tank cleanup procedure

    International Nuclear Information System (INIS)

    In late 1983, Philadelphia Electric Company (PECo) began detailed planning to replace the recirculation, residual heat removal, and part of the reactor water cleanup piping of the Peach Bottom Unit 2 reactor. Included in this work was an estimate of the collective exposure expected during piping replacement. That initial estimate, 1945 man-rem, is compared with the actual collective dose incurred during the piping replacement program. Also included are the exposures incurred during two additional tasks (safe end replacement and recirculation pump disassembly and decontamination) not considered in the initial estimate

    Full Text Available Abstract – The phenomenon of migration is one of the things which has had the greatest influence on the history of humanity, involving millions of people. Today men and women of all ages, mostly young people from economically disadvantaged areas of the planet, migrate from one continent to another, for economic, political or religious reasons. They move towards geopolitical areas which are economically and politically less troubled, leaving others where the living conditions are no longer possible. In some cases, it is a question of looking for better conditions of existence (economic causes; in other cases of mere survival (political and religious causes. Both for operational reasons and of interpretation, it is necessary to distinguish between the causes of expulsion and the consequent migration types. It is important to understand whether we are facing migration of a political or an economic nature, but it should be noted, also, that it is increasingly difficult to distinguish between politics and economics. It is a movement that creates upheaval and irreversible processes in both the countries of departure and destination. We are therefore facing a historical process of enormous importance that contributes to change the human geography and the international scene. We are facing two large economic and political areas: one of expulsion and another of attraction, with two very different types of living conditions. Every generation enjoys a condition of life and existence merely because it is born in one place rather than in another; an ascribed status that can even prevent attempts at all forms of mobility. A geographical area that is seeing its attractiveness increase is that of the EU; partly because of its colonial history, but also because of its geo-economic-political position, and also recently because of the upheavals following the fall of regimes in Eastern Europe and in the Middle East.

  20. Energy efficient data centers

    2004-03-30

    Data Center facilities, prevalent in many industries and institutions are essential to California's economy. Energy intensive data centers are crucial to California's industries, and many other institutions (such as universities) in the state, and they play an important role in the constantly evolving communications industry. To better understand the impact of the energy requirements and energy efficiency improvement potential in these facilities, the California Energy Commission's PIER Industrial Program initiated this project with two primary focus areas: First, to characterize current data center electricity use; and secondly, to develop a research ''roadmap'' defining and prioritizing possible future public interest research and deployment efforts that would improve energy efficiency. Although there are many opinions concerning the energy intensity of data centers and the aggregate effect on California's electrical power systems, there is very little publicly available information. Through this project, actual energy consumption at its end use was measured in a number of data centers. This benchmark data was documented in case study reports, along with site-specific energy efficiency recommendations. Additionally, other data center energy benchmarks were obtained through synergistic projects, prior PG&E studies, and industry contacts. In total, energy benchmarks for sixteen data centers were obtained. For this project, a broad definition of ''data center'' was adopted which included internet hosting, corporate, institutional, governmental, educational and other miscellaneous data centers. Typically these facilities require specialized infrastructure to provide high quality power and cooling for IT equipment. All of these data center types were considered in the development of an estimate of the total power consumption in California. Finally, a research ''roadmap'' was developed

  1. User-centered design

    International Nuclear Information System (INIS)

    The simplification philosophy, as an example, that both of EPRI-URD and EUR emphasize is treated mostly for the cost reduction of the nuclear power plants, but not for the simplification of the structure of user's tasks, which is one of the principles of user-centered design. A user-centered design is a philosophy based on the needs and interests of the user, with an emphasis on making products usable and understandable. However, the nuclear power plants offered these days by which the predominant reactor vendors are hardly user-centered but still designer-centered or technology-centered in viewpoint of fulfilling user requirements. The main goal of user-centered design is that user requirements are elicited correctly, reflected properly into the system requirements, and verified thoroughly by the tests. Starting from the user requirements throughout to the final test, each requirement should be traceable. That's why requirement traceability is a key to the user-centered design, and main theme of a requirement management program, which is suggested to be added into EPRI-URD and EUR in the section of Design Process.

  2. Fusion engineering design center

    International Nuclear Information System (INIS)

    In the spring of 1985, the Department of Energy (DOE) directed the Design Center to take a lead responsibility in assessing the engineering feasibility of a very compact tokamak experiment with copper coils. Following this assessment, the Design Center studied the Ignitor concept at the request of DOE and arrived at a design configuration. Many features of this configuration have been incorporated into the national baseline conceptual design for a Compact Ignition Tokamak (CIT). The Design Center continued to participate in the mirror program by contributing to the Minimars design effort, a two-year program to develop and describe an attractive tandem mirror reactor concept. The Design Center's principal role is in configuration definition of the candidate concepts. The Design Center continues to lead the engineering activities for the International Tokamak Reactor program. Advanced commercial tokamaks were studied by the Design Center as part of the Tokamak Power Systems Studies project coordinated by the DOE Office of Fusion Energy. The Design Center also provided design integration of the US effort. A cost accounting system that is applicable to all magnetic fusion reactor design studies was developed and applied to different confinement concepts and types of projects. The system provides the structure for development of a fusion cost database and validated cost estimating procedures

    In a typical optical system, optical elements usually need to be precisely positioned and aligned to perform the correct optical function. This positioning and alignment involves securing the optical element in a holder or mount. Proper centering of an optical element with respect to the holder is a delicate operation that generally requires tight manufacturing tolerances or active alignment, resulting in costly optical assemblies. To optimize optical performance and minimize manufacturing cost, there is a need for a lens mounting method that could relax manufacturing tolerance, reduce assembly time and provide high centering accuracy. This paper presents a patent pending lens mounting method developed at INO that can be compared to the drop-in technique for its simplicity while providing the level of accuracy close to that achievable with techniques using a centering machine (usually innovative auto-centering method is based on the use of geometrical relationship between the lens diameter, the lens radius of curvature and the thread angle of the retaining ring. The autocentering principle and centering test results performed on real optical assemblies are presented. In addition to the low assembly time, high centering accuracy, and environmental robustness, the INO auto-centering method has the advantage of relaxing lens and barrel bore diameter tolerances as well as lens wedge tolerances. The use of this novel lens mounting method significantly reduces manufacturing and assembly costs for high performance optical systems. Large volume productions would especially benefit from this advancement in precision lens mounting, potentially providing a drastic cost reduction.

    Peroral endoscopic myotomy (POEM) was first performed in 2008 as a novel treatment of achalasia. It is now performed globally, demonstrating the evolution of the first successful natural orifice transluminal endoscopic surgery (NOTES) procedure. There is extensive data demonstrating the safety and efficacy of POEM, and now long-term data has emerged demonstrating that the efficacy is durable. POEM is also being used to successfully treat diffuse esophageal spasm (DES) and jackhammer esophagus. With jackhammer esophagus and DES, inclusion of the lower esophageal sphincter in the myotomy minimizes the risk of symptom development from iatrogenic ineffective esophageal motility. PMID:27036895

  14. Intentional forgetting: note-taking as a naturalistic example.

    Science.gov (United States)

    Eskritt, Michelle; Ma, Sierra

    2014-02-01

    In the present study, we examined whether note-taking as a memory aid may provide a naturalistic example of intentional forgetting. In the first experiment, participants played Concentration, a memory card game in which the identity and location of pairs of cards need to be remembered. Before the game started, half of the participants were allowed to study the cards, and the other half made notes that were then unexpectedly taken away. No significant differences emerged between the two groups for remembering identity information, but the study group remembered significantly more location information than did the note-taking group. In a second experiment, we examined whether note-takers would show signs of proactive interference while playing Concentration repeatedly. The results indicated that they did not. The findings suggest that participants adopted an intentional-forgetting strategy when using notes to store certain types of information. PMID:24014168

    2007-12-01

    Full Text Available This research note is the result of the authors' reflections on epistemological issues in respect to the financial accounting field. From an epistemological perspective, this document attempts to trace the philosophical, historical, sociological, and discursive research perspectives that have guided academic research in the field of financial accounting. In order to do so, this document explores the distinctions and connections between accounting theory and accounting practice, which we believe is the first step towards understanding accounting as a scientific discipline. We analyze the theories underpinning financial accounting research, discussing its purposes, historic evolution, and scientific methods used. This document also discuss the sociological and discursive contexts of financial accounting in order to demonstrate that, like every other social science, accounting research is based upon assumptions about the nature of it players, or social networks. This document does not have the pretension to cover or close the discussion about all the pitfalls of this complex topic. In this sense, we try to document our analysis and draw some arguments in order to offer evidence for further discussion.Este ensaio teórico é resultado de reflexões dos autores acerca de questões epistemológicas sobre a contabilidade financeira.
