  3. Cavern disposal concepts for HLW/SF: assuring operational practicality and safety with maximum programme flexibility

    International Nuclear Information System (INIS)

    Most conventional engineered barrier system (EBS) designs for HLW/SF repositories are based on concepts developed in the 1970s and 1980s that assured feasibility with high margins of safety, in order to convince national decision makers to proceed with geological disposal despite technological uncertainties. In the interval since the advent of such 'feasibility designs', significant progress has been made in reducing technological uncertainties, which has lead to a growing awareness of other, equally important uncertainties in operational implementation and challenges regarding social acceptance in many new, emerging national repository programs. As indicated by the NUMO repository concept catalogue study (NUMO, 2004), there are advantages in reassessing how previous designs can be modified and optimised in the light of improved system understanding, allowing a robust EBS to be flexibly implemented to meet nation-specific and site-specific conditions. Full-scale emplacement demonstrations, particularly those carried out underground, have highlighted many of the practical issues to be addressed; e.g., handling of compacted bentonite in humid conditions, use of concrete for support infrastructure, remote handling of heavy radioactive packages in confined conditions, quality inspection, monitoring / ease of retrieval of emplaced packages and institutional control. The CAvern REtrievable (CARE) concept reduces or avoids such issues by emplacement of HLW or SF within multi-purpose transportation / storage / disposal casks in large ventilated caverns at a depth of several hundred metres. The facility allows the caverns to serve as inspectable stores for an extended period of time (up to a few hundred years) until a decision is made to close them. At this point the caverns are backfilled and sealed as a final repository, effectively with the same safety case components as conventional 'feasibility designs'. In terms of operational practicality an d safety, the CARE

  8. Nuclear quality assurance operating philosophy: A quality-oriented approach

    International Nuclear Information System (INIS)

    Quality assurance programs have been part of the nuclear utility management process since the publication of the draft of 10CFR50 Appendix B in the late 1960s. The unwritten operational philosophy of nuclear quality assurance organizations focused on compliance with federal regulations. Adverse experiences, including operational events and extended shutdowns, prompted the gradual adoption of isolated practices extending beyond compliance orientation. These practices have an orientation that accommodates a definition of quality, a perspective of the role of nuclear quality assurance organizations in the overall concept of defense-in-depth, a definition of the segments of the nuclear quality assurance mission, and recent advances in the understanding of self-assessment. Observation of these practices at various nuclear utilities resulted in a syntheses of practices and approaches into a coherent quality-oriented nuclear quality assurance operating philosophy that is not totally adopted at any one utility

  12. An operational health physics quality assurance program

    International Nuclear Information System (INIS)

    DOE Order 5700.6C, Quality Assurance, stipulates QA requirements for all DOE activities. This order is now codified as 10CFR830.120, Nuclear Safety Management, Quality Assurance Requirements, which is applicable to DOE nuclear facilities. A Quality Assurance Management Plan (QAMP) was developed by the Health Physics Operations Group (ESH-1) at Los Alamos National Laboratory (LANL). The goal of the ESH-1 QAMP is to ensure that operational radiation protection activities meet the criteria outlined in DOE Order 5700.6C, DOE-ER-STD-6001-92 and 10CFR830.120. The ten required elements are QA Program, Personal Training and Qualifications, Quality Improvement, Documents and Records, Work Processes, Design, Procurement, Inspection and Acceptance Testing, Management Assessment and Independent Assessment. The QAMP has been useful for the development of QAMPs at nuclear facilities and has helped ensure uniformity of institutional requirements where Health Physics services are deployed to facilities. To implement a subset of QAMP requirements, a Quality Assurance Self-Evaluation Program (QASE) was established. This program provides a novel self-audit mechanism for the formal identification and correction of non-conforming items related to Operational Health Physics. Additionally, the QASE is a useful management tool for Radiological Control Technician Supervisors and staff and provides a tracking mechanism for ongoing problem areas. Data have been Collected for two calendar years on a number of concerns that fall into four general categories: radiological posting and labeling, instrumentation, monitoring requirements, and radiological documents/records

  18. Quality assurance of reactor operation by computer methods

    International Nuclear Information System (INIS)

    The necessity and value of computer auditing has been proven at N Reactor. During a recent audit, discrepancies were noted when temperature calculations did not agree within +- 10F upon comparison of Quality Assurance and Reactor Operations calculations. Input data was checked and no discrepancies noted. Quality Assurance and Reactor Operations programs were executed again, using new data, and all calculations agreed within the required accuracy. A subsequent diagnostics test was performed on the Quality Assurance computer system, revealing hard (gross) computer memory failures, although further routine computer operation did not reveal this. The incident demonstrates that errors in operating limits could occur, undetected, if reliability were based solely on limits calculated by the Reactor Operations computer, without verification by means of the Quality Assurance computer. This type of incident is similarly possible at Commercial nuclear facilities which rely on one computer system only, without verification (auditing) of input parameters, subsequent calculation of operating parameters (limits), and computer operation

    1993-01-01

    Mission Operations and Command Assurance (MO&CA), a recent addition to flight operations teams at JPL. provides a system level function to instill quality in mission operations. MO&CA's primary goal at JPL is to help improve the operational reliability for projects during flight. MO&CA tasks include early detection and correction of process design and procedural deficiencies within projects. Early detection and correction are essential during development of operational procedures and training of operational teams. MO&CA's effort focuses directly on reducing the probability of radiating incorrect commands to a spacecraft. Over the last seven years at JPL, MO&CA has become a valuable asset to JPL flight projects. JPL flight projects have benefited significantly from MO&CA's efforts to contain risk and prevent rather than rework errors. MO&CA's ability to provide direct transfer of knowledge allows new projects to benefit directly from previous and ongoing experience. Since MO&CA, like Total Quality Management (TQM), focuses on continuous improvement of processes and elimination of rework, we recommend that this effort be continued on NASA flight projects.

    Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

    2011-01-01

    Full Text Available Key to the transformation of the South African higher education landscape has been the introduction and enhancement of quality assurance practices. The implementation of quality assurance mechanisms in the sector has also affected academic libraries, as they are not static, free-standing entities but are part of universities and their academic culture. Evidently, quality assurance is no longer an option, but a critical reality as libraries in general are under immense pressure to prove their worth in competition with other information enterprises, and are also facing budget cuts (Kinnell, Usherwood, & Jones 1999; Tam 2000. Academic libraries, in particular, are facing the extra challenge of striving to align quality initiatives and practices not only with the overall mission and goals of the university, but also with the “fitness for purpose” quality principle by which universities are judged by the Higher Education Quality Committee (HEQC. The study utilised questionnaires and document analysis to collect data and targeted officers in academic libraries who deal with quality assurance matters or issues as well as policy or other related documents. The results showed that quality assurance practices in academic libraries vary. They range from active and integrative processes for maintaining and improving quality to those that are feeble and not well developed. However, there is general commitment towards instilling a quality culture, encouraging a best practice, participative approach, continuous improvement and satisfying the needs of the customer. As one of its recommendations, the study highlights the need to enhance the depth and breadth of quality assurance initiatives and to create more avenues for sharing best practices.

  4. The role of the operating organization in NPP quality assurance

    International Nuclear Information System (INIS)

    In the USSR, quality assurance problems (planning and systematic implementation of activities) associated with the construction and operation of nuclear power plants are the responsibility of the Ministry of Atomic Energy and Industry. One section of that Ministry fulfils the function of the operating body. Corporations that take part in the activities throughout the various stages of the nuclear power plant life are fully responsible for quality assurance in allocated fields only, while the body operating the plant is responsible for the overall fulfilment of the quality assurance plan at the nuclear power plant. The operating body creates the organizational structure necessary for safe nuclear power plant operation; it procures funds, materials, technical means, standards and other technical documentation; organizes physical protection and fire protection of the plant and selection and training of the operating personnel; and it supervises constantly all activities relevant to the safety aspect and is responsible for them. The results of safety-related inspections are submitted by the plant-operating body to State Surveillance and inspection authorities. The plant-operating body elaborates and, together with State Surveillance bodies, approves methodologies and programmes for the preparation and implementation of training in case of accident, and organizes this training. At present, a nuclear power plant quality assurance programme is being prepared taking into account IAEA and ISO recommendations. (Z.S.). 4 refs

  11. Roles of the operator and the safety services in nuclear power plant quality assurance

    International Nuclear Information System (INIS)

    With regard to the operation of nuclear power plants, Electricite de France formally recognized in 1973 that it was necessary for safety reasons and economically acceptable to adopt organizational principles of quality assurance that would be applicable both to its own activities and to those of its suppliers. Generally speaking, the form and spirit of the quality assurance programme chosen is based largely on the Code of Practice No. 50-C-QA. In particular, the programme focuses on the flexible character of quality assurance requirements and stresses that in the final analysis product quality depends above all on those to whom the project has been assigned, because it is they who are responsible for meeting the quality objectives set. Ten years of experience with the suppliers of Electricite de France has shown that these suppliers, after some initial difficulty, have been able to adapt the application of quality assurance so as to achieve satisfactory quality as regards both safety and availability. In the case of the French standard nuclear power plants, quality assurance is particularly important thanks to the traceability which it affords and to the allowance for corrective measures which it demands. The safety services normally take action related to quality assurance in three ways: through regulation, the analysis of measures to assure plant safety, and plant supervision. As regards regulation, an order has just been published relating to design, construction and operational quality in base-load nuclear power plants. The requirements laid down in this document incorporate the recommendations of the IAEA Code on quality assurance. (author)

  12. The role of quality assurance in future midwifery practice.

    Science.gov (United States)

    Dawson, J

    1993-08-01

    Recent recommendations have been made which would give midwives a more central role in maternity care and a greater degree of independence than they currently enjoy. This paper argues that midwives' current attitudes to quality assurance are incompatible with this enhanced role. Research conducted in three health districts is described, which explored the perceptions of nurses, midwives and managers towards quality assurance. The findings indicate that quality assurance (in whatever form that concept is operationalized) is a demonstration of accountability. For managers this accountability is primarily for the service as a whole, whilst nurses and midwives view their accountability as being owed to patients/clients. The main methodology which the study identified as being used for monitoring nursing care was the development and auditing of explicit standards. This approach has been actively promoted by the Royal College of Nursing, enabling nurses to regain control of the purely professional aspects of the nursing profession. Midwives in the study districts showed a marked reluctance to adopt such a strategy, taking the view that as independent practitioners consensus standards would be unacceptable. It is argued that this attitude is inconsistent with the basic principle that professionals are accountable for both demonstrating and developing the quality of professional practice. It is further suggested that midwives currently have an opportunity to regain professional control of midwifery practice, which will be lost unless they are prepared to take responsibility for evaluating the standards for which they are accountable.

  14. Quality assurance - the key to safety and availability during operation

    International Nuclear Information System (INIS)

    Social demands require that the trust and acceptance of the critical general public be attained by demonstrating the safety and quality of nuclear installations. Efforts in recent years have therefore focused on thorough (planning, erection, operation) quality assurance as part of an effective system analysis. Here logistical QA management of the operation of nuclear power plants assumes a key role in terms of safety and availability. The QA option also enables enhancement of cost-effectiveness in all process-oriented areas from production, preventive and corrective maintenance to plant monitoring and in-service inspections. Quality assurance is therefore synonymous with organizational, personnel and technical aspects of plant management. Selected examples are used to illustrate where quality assurance can make valuable contributions to improving plant management: plant organization and the description of relevant work sequences; man/machine interface and the importance of communication; selective maintenance and in-service inspections with reliable information on quality; updating of plant documentation; quality audit by QA specialists as a monitoring and feedback system.

    2014-01-01

    At present, the American Dental Association and the American Academy of Oral Maxillofacial Radiology have guidelines for the dental environment that include quality assurance and control of film-based radiography. Approximately 19%-30% of US dental offices currently use some form of digital intraoral radiography, and growth is expected to continue. It is anticipated that new tools and guidelines will be needed to aid in the development of quality assurance (QA) and control of digital intraoral radiographic images. Working with a representative sample of private practice dental offices, this study examined and evaluated the entire digital intraoral radiographic system used in each operatory. The X-ray machine was tested for equipment performance and accuracy, and the computer monitor calibration was evaluated and adjusted as needed. The results confirm the continued need for updated QA procedures in the dental office that include digital X-ray imaging. By implementing these changes and practices, dentists should be able to improve the diagnostic quality of radiographs while reducing the radiation exposure of the patient. PMID:25184710

    Cardiovascular computed tomography (CCT) is a cutting-edge imaging technique providing important, non-invasive, diagnostic information. Concerns exist regarding radiation exposure to patient populations, but achieving optimal image quality at the lowest doses can be challenging. This guide provides practical advice about how quality can be assured in any CCT unit or radiology department. Illustrated by real-world vignettes and data analysis from our own experience, we highlight a multidisciplinary team approach to each stage of the patient journey, the effectiveness of regular dose audit overseen by a CT optimisation group, and the importance of underused systolic scanning techniques, in order to drive significant dose reduction without loss of image quality or clinical confidence.

    International Nuclear Information System (INIS)

    The half-lives of the positron-emitting radioisotopes, carbon-11 (t1/2 = 20.3 min) and fluorine-18 (t1/2 = 109.6 min), preclude lengthy techniques from the routine analysis of radiopharmaceuticals derived for positron emission tomography (PET). Therefore, the assurance of radiopharmaceutical quality, with respect to safety and efficacy, should rely heavily on establishing a well-defined production protocol that delivers a high quality product from materials of specified grade. Also, this protocol should be supported routinely by rapid quality control procedures. Such a combination constitutes good manufacturing practice (GMP) in radiopharmaceutical production for PET. This talk will describe the application of GMP, in a PET centre regularly producing a wide range of 11C- and 18F-radiopharmaceuticals

    We report the establishment of a voluntary programme for developing the assessment of professional practice and quality assurance conducted since 1989 in the Aquitaine region of south-west France. This experience, in a region where there are 14,000 hospital beds in about a hundred institutions, has aimed at two objectives: (1) the adoption by the region's health professionals of medical guidelines for good practice and methods for measuring quality and outcomes obtained, by means of university training in evaluation and the conducting of several surveys of professional practice and clinical audits; (2) similar adoption by the regional political, administrative and medical directors of quality assurance procedures defined by an organizational audit concerning the prescription of preoperative tests in the university hospital and in the main public hospitals of the region. The critical impetus that this experience has created, together with other factors related to the political decision-makers and health managers of the region, has led to an operational regional structure for developing clinical evaluation and quality in Aquitaine.

  3. Reestablishing the engineering/quality-assurance interface for operations and maintenance

    International Nuclear Information System (INIS)

    People involved in the construction of nuclear power plants over the past several years know there has been a weakening of the role of the engineer during construction. There have been too many instances when the role of the quality assurance (QA) organization has been expanded to the point where QA groups are making many of the engineering decisions. This extremely bad practice cannot be allowed to carry over into the operation and maintenance phase of nuclear power plants. The US Nuclear Regulatory Commission (NRC) will be closely scrutinizing the operations and maintenance of these plants, and management will be required to show the regulators a strong program that will ensure the continued operation of the power plant involved. This paper discusses the role of management and the support that must be given this role by both the engineering and the QA organizations

  4. The Role Of Quality Assurance Program For Safety Operation Of Nuclear Installations

    International Nuclear Information System (INIS)

    Nuclear installations expose potential hazard of radiation, therefore in their construction, operation and maintenance, it is necessary to consider safety aspect, in which the safety requirements which has been determined must be met. One of the requirements that is absolutely needed is quality assurance, which covers arrangement of quality assurance program, organization and administration of the implementation of quality assurance, and supervision. Quality Assurance program is a guideline containing quality policies and basic determination on the realization of activities that effect the quality of equipment's and items used in the operation of nuclear installations in order that the operation of nuclear installation can run safety and in accordance with their design aims and operation limits. Quality Assurance Program includes document control, design control, supply control, control of equipment s and items, operation/process control, inspection and control of equipment test, and control of nonconformance and corrections. General system of nuclear installation operation is equipped with safety and supporting systems. These systems must apply the quality assurance program that cover control of activities in the systems. In the implementation of the quality assurance program, it is necessary to establish procedures, work guidelines/instructions, and quality recording that constitutes documents of quality system 2nd, 3th, and 4th level after the quality assurance program. To ensure the effectivity and to prove whether the realization of the program has been pursuant to the determined requirements, an internal audit must be conducted accordingly

  8. Role of current good manufacturing practices in establishment of quality assurance for in-house radiopharmaceuticals

    International Nuclear Information System (INIS)

    The ultimate goal in any facility involved in the preparation of radiopharmaceuticals should be the production of products that are as safe and effective as possible. Following Current Good Manufacturing Practices (CGMPs) is the best way to assure the final product quality, even for in-house preparation and for those facilities operating under Nuclear Pharmacy auspices. In some facilities this places the chemist in a unique role of not only being responsible for R ampersand D, but for designing quality into all levels of product planning, including targetry, synthesis, purification, and quality control. The incorporation of certain minimum standards into the establishment of QA is discussed in general and is illustrated using the preparation of cyclotron-produced products, particularly 2-[F-18]fluoro-2-deoxy-D-glucose(FDG) and high purity Indium-111 chloride

  9. Integrating Safety and Mission Assurance into Systems Engineering Modeling Practices

    Beckman, Sean; Darpel, Scott

    2015-01-01

    During the early development of products, flight, or experimental hardware, emphasis is often given to the identification of technical requirements, utilizing such tools as use case and activity diagrams. Designers and project teams focus on understanding physical and performance demands and challenges. It is typically only later, during the evaluation of preliminary designs that a first pass, if performed, is made to determine the process, safety, and mission quality assurance requirements. Evaluation early in the life cycle, though, can yield requirements that force a fundamental change in design. This paper discusses an alternate paradigm for using the concepts of use case or activity diagrams to identify safety hazard and mission quality assurance risks and concerns using the same systems engineering modeling tools being used to identify technical requirements. It contains two examples of how this process might be used in the development of a space flight experiment, and the design of a Human Powered Pizza Delivery Vehicle, along with the potential benefits to decrease development time, and provide stronger budget estimates.

  10. Relevant aspects of a quality assurance program applied to a nuclear power plant operation

    International Nuclear Information System (INIS)

    The purpose of this work was to enumerate the most relevant subjects to be taken into account for the elaboration of a Quality Assurance Program aimed to regulate a nuclear power plant operation. At first, it was necessary to point out the relevance that implies the presence of a group of personnel, experienced in quality assurance with enough knowledge on the technical and organizing aspects of the plant. Other aspect to be taken into account was the contemplation of the international requirements, through the International Atomic Energy Agency and of the national requirements that each country had set up by the corresponding regulating agencies. These organizations pointed out the minimum rules that must be followed for the adequate and efficient execution of a program. The Quality Assurance Manual and the program and work procedures constituted the Quality Assurance Program which must be checked as regards its fulfillment by auditors and quality assurance supervisions.

    Ross, Alastair

    2015-08-01

    Research and development can be classified into three categories: technology adoption, technology extension, and knowledge and technology creation. In general, technology adoption is embedded in operational forensic science laboratory practice but the latter two categories require partnerships with industry and/or academia both to conduct the research and implement the outcomes. In a 2012 survey, Australian and New Zealand forensic science laboratories identified a number of 'roadblocks' to undertaking research and operationalizing research outcomes. These included insufficient time and funding, a lack of in-house research experience and the absence of a tangible research culture. Allied to this is that, increasingly, forensic science research is conducted in a 'commercial in confidence' environment and the outcomes are not readily or cost-effectively available to be integrated into operational forensic science laboratories. The paper is predominantly reflective of the current situation in Australia and New Zealand. PMID:26101286

  12. Assuring human operator alertness at night in power plants

    International Nuclear Information System (INIS)

    The human body is not designed for peak alertness and performance at night, nor is it well-equipped to cope with the frequent day-night inversions required by rotating shift work schedules. As a result, the human operator can become the weak link in a complex technological operation such as a nuclear power plant. The high degree of dependence on human operator vigilance, decision-making ability and performance that is required in nuclear power plant operations can conflict with the human sleepiness and error-proneness which naturally occur during the night shift or after extended periods without adequate sleep. An opportunity to address these problems has come from a series of major research advances in basic circadian physiology

  15. Quality assurance programme implementation and monitoring during operation

    International Nuclear Information System (INIS)

    AIB-Vincotte Nuclear performs regulatory inspections and QA audits in the Belgian nuclear power plants and has also performed various QA audits and safety evaluations in nuclear power plants abroad. Experience is presented gained through periodic inspections and through overall audits of QA programmes and their implementation. The auditing personnel being very familiar with the day-to-day practice in nuclear plants, QA has been approached systematically from a practical point of view. This means that a QA programme is looked upon as a support for the daily tasks from management level to the work floor in order to achieve the required quality and safety. Special items that are addressed are: general policy regarding QA, management objectives, QA as a management tool, definition of quality, training of personnel and of auditors, motivation of personnel. Specific examples of problems encountered are mentioned. (author)

  16. Experience in the implementation of quality assurance program and safety culture assessment of research reactor operation and maintenance

    International Nuclear Information System (INIS)

    The implementation of quality assurance program and safety culture for research reactor operation are of importance to assure its safety status. It comprises an assessment of the quality of both technical and organizational aspects involved in safety. The method for the assessment is based on judging the quality of fulfillment of a number of essential issues for safety i.e. through audit, interview and/or discussions with personnel and management in plant. However, special consideration should be given to the data processing regarding the fuzzy nature of the data i.e. in answering the questionnaire. To accommodate this situation, the SCAP, a computer program based on fuzzy logic for assessing plant safety status, has been developed. As a case study, the experience in the assessment of Kartini research reactor safety status shows that it is strongly related to the implementation of quality assurance program in reactor operation and awareness of reactor operation staffs to safety culture practice. It is also shown that the application of the fuzzy rule in assessing reactor safety status gives a more realistic result than the traditional approach. (author)

The P2TBDU Quality Assurance Program has been arranged and put into force since 1993, however the implementation of the program has not been effective as expected. The change of organization structure shall cause the changes of organisation's function and main duty, therefore it requires that the change/revision be made to accommodate the new policy on the quality assurance program. The Quality Assurance Program revision 1 has been arranged and put into force since Nov. 19, 1999 which incorporated the change of the organizational structure. The effectiveness of implementation of the program shall extremely be determined y commitment of the P2TBDU management as well as awareness of each personal of the organization on the necessity of Quality Assurance Program for operational safety of the installation.

  18. Quality assurance in radiochemistry - a report from practice

    International Nuclear Information System (INIS)

    The Department of Nuclear Medicine in Muenster has been certified since January 17th 2003 by external auditing according to DIN EN ISO 9001:2000. The compliance with EN ISO 9001:2000 was approved by the European Association of Nuclear Medicine (EANM) in August 2003. To date, the certificate assignment (No. 2384D) to the nuclear medicinal facilities of the University Hospital in Muenster (UKM) is unique in Germany particularly because the certification not only covers the diagnostic and therapeutical scope of the Department of Nuclear Medicine but also for the first time contains the in-house-production of radionuclides and radiopharmaceuticals including radioactive waste disposal. Consequently, the routine duties and responsibilities of a section radiochemistry which is imbedded in a clinical organisation have been standardised and well documented for the first time according to DIN EN ISO 9001:2000. The operational procedures for radiopharmaceutical chemistry are documented in the work areas 'conventional' radiochemistry laboratory (radionuclide laboratory) as well as modern production facility for PET radiochemistry. The implementation of standard operational procedures (SOPs) cause an increase of efficiency in a radiochemistry task group with two graduate radiopharmaceutical chemists and two well-trained technical/laboratory assistants.

    The Nondestructive Analysis (NDA) Facility at the Oak Ridge Y-12 Plant has characterized process wastes for Enriched Uranium Operations since 1978. Since that time, over 50,000 items have been analyzed. Analysis results are used to determine whether or not recovery of uranium from process wastes is economically feasible. Our instrument complement includes one large segmented gamma scanner (SGS), two smaller SGS, two solution assay systems (SAS), and Active Well Coincidence Counter (AWCC). The large SGS is used for analyzing High Efficiency Particulate Air (HEPA) filters ant 208-L drums filled with combustible contaminated waste. The smaller SGS are used to analyze 4-L containers of ash and leached residues. The SAS are used to analyze 125 ml bottles of aqueous or organic waste solutions that may contain uranium. The gamma-based NDA techniques are used to identify which process wastes can be discarded, and which must be recycled. The AWCC is used to analyze high-density materials which are not amenable to gamma-ray analysis. 1 ref., 4 figs.

  1. Quality assurance aspects during design, construction and operation of a repository for radioactive wastes

    International Nuclear Information System (INIS)

    Quality assurance (QA) with regard to structures, systems and components is an important task during design, construction and operation of a repository for the final disposal of radioactive wastes. Therefore, an appropriate QA system has to be established and to be described in a general QA manual. A separate QA manual has to be prepared for the operational phase of a repository. A further QA activity is to classify the structures, systems and components of the repository into different areas (QA grading). This classification can be based on the results of a comprehensive safety assessment. Type and extent of the necessary documentation strongly depend on the relevance of the structures, systems and components to safety. Quality assurance procedures are necessary in the operational phase, especially in cases of deviations from the licensed status and of nonconformances. Changes during design, construction and operation are also categorized. (orig.)

    A preliminary survey of existing separation assurance and collision avoidance advancements, technologies, and efforts has been conducted in order to develop a concept of operations for flight testing autonomous separation assurance at Dryden Flight Research Center. This effort was part of the Unmanned Aerial Systems in the National Airspace System project. The survey focused primarily on separation assurance projects validated through flight testing (including lessons learned), however current forays into the field were also examined. Comparisons between current Dryden flight and range assets were conducted using House of Quality matrices in order to allow project management to make determinations regarding asset utilization for future flight tests. This was conducted in order to establish a body of knowledge of the current collision avoidance landscape, and thus focus Dryden s efforts more effectively towards the providing of assets and test ranges for future flight testing within this research field.

  6. Clinical Practice and Quality Assurance Challenges in Modern Brachytherapy Sources and Dosimetry

    International Nuclear Information System (INIS)

    Modern brachytherapy has led to effective treatments through the establishment of broadly applicable dosimetric thresholds for maximizing survival with minimal morbidity. Proper implementation of recent dosimetric consensus statements and quality assurance procedures is necessary to maintain the established level of safety and efficacy. This review classifies issues as either 'systematic' or 'stochastic' in terms of their impact on large groups or individual patients, respectively. Systematic changes affecting large numbers of patients occur infrequently and include changes in source dosimetric parameters, prescribing practice, dose calculation formalism, and improvements in calculation algorithms. The physicist must be aware of how incipient changes accord with previous experience. Stochastic issues involve procedures that are applied to each patient individually. Although ample guidance for quality assurance of brachytherapy sources exists, some ambiguities remain. The latest American Association of Physicists in Medicine guidance clarifies what is meant by independent assay, changes source sampling recommendations, particularly for sources in sterile strands and sterile preassembled needles, and modifies action level thresholds. The changing environment of brachytherapy has not changed the fact that the prime responsibility for quality assurance in brachytherapy lies with the institutional medical physicist

  7. Quality assurance in the field of nuclear power, international and Romanian practice

    International Nuclear Information System (INIS)

    Electricity should be generated in nuclear power plants under nuclear safety regulations with a high reliability level. In order to achieve this requirement it is necessary to work under quality assurance (QA) mode. The term of 'quality assurance' was used for the first time in USA in 1967. Since then, the situation has continuously developed. The most comprehensive standards in the fields are the USA ones. The IAEA agency in Vienna developed the first standards in 1978. The developed countries have their own legislation in the field. The IAEA standards, are based on the USA, German, Japanese, British, Canadian and French legislation. Romania drafted the Law No. 6/1982, repealed by the Law No. 11 in 1996. There is no satisfactory Romanian standard at present to regulate the activities of quality assurance in the nuclear power field. The works at Unit 1 of Cernavoda nuclear power plant were performed under the Canadian QA standards. The Canadian nuclear power company Ontario Hydro has been lately confronted with difficulties that may lead to decommission of 7 out of 19 units now in operation. To avoid the Canadian system deficiencies Romania needs standards based on the experience gained in this field by all developed countries, such as: USA, Japan, Germany, France, etc and IAEA regulations. The present paper is a pleading in favour of the Romanian legislation drafting at the level of the international demands. (author)

  8. Good practices in heavy water reactor operation

    International Nuclear Information System (INIS)

    The value and importance of organizations in the nuclear industry engaged in the collection and analysis of operating experience and best practices has been clearly identified in various IAEA publications and exercises. Both facility safety and operational efficiency can benefit from such information sharing. Such sharing also benefits organizations engaged in the development of new nuclear power plants, as it provides information to assist in optimizing designs to deliver improved safety and power generation performance. In cooperation with Atomic Energy of Canada, Ltd, the IAEA organized the workshop on best practices in Heavy Water Reactor Operation in Toronto, Canada from 16 to 19 September 2008, to assist interested Member States in sharing best practices and to provide a forum for the exchange of information among participating nuclear professionals. This workshop was organized under Technical Cooperation Project INT/4/141, on Status and Prospects of Development for and Applications of Innovative Reactor Concepts for Developing Countries. The workshop participants were experts actively engaged in various aspects of heavy water reactor operation. Participants presented information on activities and practices deemed by them to be best practices in a particular area for consideration by the workshop participants. Presentations by the participants covered a broad range of operational practices, including regulatory aspects, the reduction of occupational dose, performance improvements, and reducing operating and maintenance costs. This publication summarizes the material presented at the workshop, and includes session summaries prepared by the chair of each session and papers submitted by the presenters

    This document describes a Concept of Operations (ConOps) for an Integrated Vehicle Health Assurance System (IVHAS). This ConOps is associated with the Maintain Vehicle Safety (MVS) between Major Inspections Technical Challenge in the Vehicle Systems Safety Technologies (VSST) Project within NASA s Aviation Safety Program. In particular, this document seeks to describe an integrated system concept for vehicle health assurance that integrates ground-based inspection and repair information with in-flight measurement data for airframe, propulsion, and avionics subsystems. The MVS Technical Challenge intends to maintain vehicle safety between major inspections by developing and demonstrating new integrated health management and failure prevention technologies to assure the integrity of vehicle systems between major inspection intervals and maintain vehicle state awareness during flight. The approach provided by this ConOps is intended to help optimize technology selection and development, as well as allow the initial integration and demonstration of these subsystem technologies over the 5 year span of the VSST program, and serve as a guideline for developing IVHAS technologies under the Aviation Safety Program within the next 5 to 15 years. A long-term vision of IVHAS is provided to describe a basic roadmap for more intelligent and autonomous vehicle systems.

  10. Quality assurance aspects of geotechnical practices for underground radioactive waste repositories

    International Nuclear Information System (INIS)

    In August 1988, the National Research Council, through the Geotechnical Board and the Board on Radioactive Waste Management, held a colloquium to discuss the practice of quality assurance that is being implemented in the high-level radioactive waste storage program. The intent of the colloquium was to bring together program managers of the Department of Energy and Nuclear Regulatory Commission, to discuss with the technical community both the advantages and problems associated with applying current quality assurance practices to underground science and engineering. The colloquium program included talks from 14 individuals that provided a variety of perspectives on both programmatic and technical issues. The talks initiated extended discussions from the 71 participants representing 7 government agencies, 8 academic institutions, and 22 private companies. The competencies of the participants were many and varied including, among others, geochemistry, hydrology, geotechnical engineering, computer programming, engineering and structural geology, underground design and construction, rock mechanics, laboratory testing, systems engineering, nuclear engineering, law, and environmental science. Based on a transcript of the meeting, this report summarizes the talks and discussions which took place. 2 figs

    2007-01-01

    In a previous study, multiple regression techniques were applied to Flight Operations Quality Assurance-derived data to develop parsimonious model(s) for fuel consumption on the Boeing 757 airplane. The present study examined several data mining algorithms, including neural networks, on the fuel consumption problem and compared them to the multiple regression results obtained earlier. Using regression methods, parsimonious models were obtained that explained approximately 85% of the variation in fuel flow. In general data mining methods were more effective in predicting fuel consumption. Classification and Regression Tree methods reported correlation coefficients of .91 to .92, and General Linear Models and Multilayer Perceptron neural networks reported correlation coefficients of about .99. These data mining models show great promise for use in further examining large FOQA databases for operational and safety improvements.

    2006-01-01

    Knowledge Management is a proactive pursuit for the future success of any large organization faced with the imminent possibility that their senior managers/engineers with gained experiences and lessons learned plan to retire in the near term. Safety and Mission Assurance (S&MA) is proactively pursuing unique mechanism to ensure knowledge learned is retained and lessons learned captured and documented. Knowledge Capture Event/Activities/Management helps to provide a gateway between future retirees and our next generation of managers/engineers. S&MA hosted two Knowledge Capture Events during 2005 featuring three of its retiring fellows (Axel Larsen, Dave Whittle and Gary Johnson). The first Knowledge Capture Event February 24, 2005 focused on two Safety and Mission Assurance Safety Panels (Space Shuttle System Safety Review Panel (SSRP); Payload Safety Review Panel (PSRP) and the latter event December 15, 2005 featured lessons learned during Apollo, Skylab, and Space Shuttle which could be applicable in the newly created Crew Exploration Vehicle (CEV)/Constellation development program. Gemini, Apollo, Skylab and the Space Shuttle promised and delivered exciting human advances in space and benefits of space in people s everyday lives on earth. Johnson Space Center's Safety & Mission Assurance team work over the last 20 years has been mostly focused on operations we are now beginning the Exploration development program. S&MA will promote an atmosphere of knowledge sharing in its formal and informal cultures and work processes, and reward the open dissemination and sharing of information; we are asking "Why embrace relearning the "lessons learned" in the past?" On the Exploration program the focus will be on Design, Development, Test, & Evaluation (DDT&E); therefore, it is critical to understand the lessons from these past programs during the DDT&E phase.

  14. Quality control assurance for safe and reliable performance of nuclear power stations from their conceptual design to operation

    International Nuclear Information System (INIS)

    The responsibilities of design, construction, commissioning and initial operation of nuclear power plants in India rest with the Power Projects Engineering Division of the Department of Atomic Energy. Practices followed by the Division from the stage of design to the stage of operation and maintenance are described. Role of audit at every stage is explained. One of the major problems in the case of Rajasthan Atomic Power Project was to overcome the resistance of the contractor/vendor for accepting the quality assurance programme. The initial reject rate in piping was above 50%. It came down sharply when the contractor implemented the quality control scheme. It is recommended that: (1) there should be an independent agency for quality control and inspection of maintenance of the operating plant, (2) an independent audit on design with checklists for each type of design is necessary and (3) each organisation must have a separate section to collect, compile and codify data and to exchange with each other.

  15. Upgrading of quality assurance programmatic requirements for operating nuclear power plants

    International Nuclear Information System (INIS)

    As a result of the analysis of the TMI-2 accident and experience at several construction sites for nuclear power plants, the staff of the United States Nuclear Regulatory Commission (NRC) has concluded that certain quality assurance (QA) programmatic modifications relative to currently existing requirements should be made. These modifications are directed toward upgrading and strengthening the QA function at operating nuclear power plants to improve its effectiveness in identifying and correcting operational deficiencies in order to protect the public health and safety. Specific areas of QA programmatic upgrading include: 1. Improving management attitudes toward QA; 2. expanding the category of structures, systems and components to which the QA programme applies, to include all items that affect safety; 3. improving the organizational independence of the QA function from the performing functions; 4. increasing QA staffing levels and qualification requirements for QA personnel; 5. increasing the involvement of the QA organization in the inspection and verification of operational activities; and 6. increasing the involvement of the QA organization in the review and approval of quality-affecting documents. The NRC has developed new requirements in the above areas and has initiated their implementation on TMI-1 (re-start) and several other operational units at sites located near areas of high population density. It is ultimately planned to demand the implementation of these new requirements for all nuclear power plants under design and construction as well as in operation. These and other new requirements are also contemplated for implementation in new plants under design and construction. (author)

    Willenbrock, J.H.; Thomas, H.R. Jr.; Burati, J.L. Jr.

    1978-06-01

    The basic objective of this research effort was to perform a comparative analysis of the Quality Assurance practices related to the structural concrete phase on nine nuclear power plant projects which are (or have been) under construction in the United States in the past ten years. This analysis identified the response of each Quality Assurance program to the applicable criteria of 10 CFR Part 50, Appendix B as well as to the pertinent regulatory requirements and industry standards. The major emphasis was placed on the construction aspects of the structural concrete phase of each project. The engineering and design aspects were examined whenever they interfaced with the construction aspects. For those aspects of the Quality Assurance system which can be considered managerial in nature (i.e., organizational relationships, types of Quality Assurance programs, corrective action procedures, etc.) an attempt has been made to present the alternative approaches that were identified. For those aspects of the Quality Assurance system which are technical in nature (i.e., the frequency of testing for slump, compressive strength, etc.) an attempt has been made to present a comparative analysis between projects and in relation to the recommended or mandated practices presented in the appropriate industry codes and standards.

  19. The quality assurance topical report - International co-operation for manufacturing of nuclear packages

    International Nuclear Information System (INIS)

    The paper addresses the manufacturing quality assurance (QA) concerns associated with fabrication of radioactive material packaging in one country for use in another. A case study is discussed which shows a method of implementation that has been successfully practised for casks fabricated in the Federal Republic of Germany (FRG) for use in the USA. The casks utilized are the Castor series, which are fabricated in the FRG from ductile cast iron. Although international efforts have helped to standardize QA measures, detailed implementation can vary from country to country. A means of co-ordinating requirements between countries was required. The vehicle used to accomplish this was the Quality Assurance Topical Report (QATR), which is an administrative QA document that clearly defines the roles and responsibilities of all affected organizations. The close correlation of requirements is documented in the QATR. In addition, a programme is described which permits the USA competent authority to depend on the FRG authority for inspection and enforcement procedures. It is of great importance that the fabrication and inspection of any component important to safety be properly controlled and documented. The USA requirements for these QA measures are enforced by the Nuclear Regulatory Commission (NRC). Enforcement of applicable regulations in the FRG is the responsibility of the competent authority, Bundesanstalt fuer Materialpruefung (BAM). As a part of the development of this QATR, NRC and BAM representatives met to establish a mutual understanding of QA. As a result, the QATR concept has been approved by both BAM and the NRC. A problem with manufacturing equipment in a foreign country is the need to periodically send company representatives to witness hold points and to review manufacturing records. The methods described in the QATR provide a practical and workable alternative by permitting the BAM to serve as the purchaser (or utility) agent. The utility is only required

    International Nuclear Information System (INIS)

    This paper discusses the nuclear pooling system and co-operation between the pools, present practice and capacity, with a breakdown of the limits for third party liability and material damage. The author also describes the relationship between the pools and the nuclear operators (the policyholders), and concludes that the nuclear pools have been successful in serving the interests of their member companies, their policyholders and the governments as they have provided a stable insurance market by making available capacity in amounts that had never before been assembled and placed at risk in a single location. 2 tabs

  1. Introduction to quality assurance

    International Nuclear Information System (INIS)

    Safety requirements set forth in the regulatory requirement, codes, standards as well as other requirements for various aspects of nuclear power plant design and operation are strictly implemented through QA activities. The overall QA aim is to assure that the plant is soundly and correctly designed and that it is built, tested and operated in accordance with stringent quality standards and conservative engineering practices. In this way a high degree of freedom from faults and errors can be achieved. (orig.)

  2. Developing and theoretically justifying innovative organizational practices in health information assurance

    Science.gov (United States)

    Collmann, Jeff R.

    2003-05-01

    This paper justifies and explains current efforts in the Military Health System (MHS) to enhance information assurance in light of the sociological debate between "Normal Accident" (NAT) and "High Reliability" (HRT) theorists. NAT argues that complex systems such as enterprise health information systems display multiple, interdependent interactions among diverse parts that potentially manifest unfamiliar, unplanned, or unexpected sequences that operators may not perceive or immediately understand, especially during emergencies. If the system functions rapidly with few breaks in time, space or process development, the effects of single failures ramify before operators understand or gain control of the incident thus producing catastrophic accidents. HRT counters that organizations with strong leadership support, continuous training, redundant safety features and "cultures of high reliability" contain the effects of component failures even in complex, tightly coupled systems. Building highly integrated, enterprise-wide computerized health information management systems risks creating the conditions for catastrophic breaches of data security as argued by NAT. The data security regulations of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) implicitly depend on the premises of High Reliability Theorists. Limitations in HRT thus have implications for both safe program design and compliance efforts. MHS and other health care organizations should consider both NAT and HRT when designing and deploying enterprise-wide computerized health information systems.

  6. Comprehensive audits of radiotherapy practices: A tool for quality improvement: Quality Assurance Team for Radiation Oncology (QUATRO)

    International Nuclear Information System (INIS)

    As part of a comprehensive approach to quality assurance (QA) in the treatment of cancer by radiation, an independent external audit (peer review) is important to ensure adequate quality of practice and delivery of treatment. Quality audits can be of various types and at various levels, either reviewing critical parts of the radiotherapy process (partial audits) or assessing the whole process (comprehensive audits). The IAEA has a long history of providing assistance for dosimetry (partial) audits in radiotherapy to its Member States. Together with the World Health Organization (WHO), it has operated postal audit programmes using thermoluminescence dosimetry (TLD) to verify the calibration of radiotherapy beams since 1969. Furthermore, it has developed a set of procedures for experts undertaking missions to radiotherapy hospitals in Member States for on-site review of dosimetry equipment, data and techniques, measurements and training of local staff. This methodology involves dosimetry and medical radiation physics aspects of the radiotherapy process without entering into clinical areas. The IAEA, through its technical cooperation programme, has received numerous requests from developing countries to perform comprehensive audits of radiotherapy programmes to assess the whole process. including aspects such as organization, infrastructure, and clinical and medical physics components. The objective of a comprehensive clinical audit is to review and evaluate thc quality of all of the components of the practice of radiotherapy at an institution, including its professional competence, with a view to quality improvement. A multidisciplinary team, comprising a radiation oncologist, a medical physicist and a radiotherapy technologist, carries out the audit. The present publication has been field tested by IAEA teams performing audits in radiotherapy programmes in hospitals in Africa, Asia, Europe and Latin America. Their comments, corrections and feedback have been taken

  7. Newer approaches and developments of quality assurance procedures for intrabeam intra operative radiotherapy unit

    International Nuclear Information System (INIS)

    The authors present new QA procedures for Intrabeam intra-operative radiation therapy (IORT) system which address some of the limitations of the inbuilt QA procedures and provide various other measurements over the existing QA procedures. Intrabeam System (manufactured by Carl Zeiss, Oberkochen, Germany), is an intraoperative radiotherapy unit. It is a miniature, high dose rate, low energy X-ray source (XRS) equipped with a 10 cm long (0 3.2 mm) probe. Currently IORT systems rely on inbuilt QA methods for verification of output, beam deflection, isotropy and straightness of the probe. While manufacturer specified inbuilt QA procedures are more frequently used, it will not give full confidence especially at the time of installation and commissioning The new approach provides isotropy, beam deflection, isodose output measurements, KVp and MAs measurements, beam quality, energy stability verification, reproducibility and linearity. These tests and measurements also help us to use the computerized planning systems in which we are able to see the 2D and 3D dose distributions on the CT data which is not available at present on this system. In an IORT facility, the quality assurance needs to be more stringent due to the miniature x-ray source and its high dose rate. These new QA results were compared to the existing readings with the inbuilt QA procedures

  8. Evaluation of High Density Air Traffic Operations with Automation for Separation Assurance, Weather Avoidance and Schedule Conformance

    Science.gov (United States)

    Prevot, Thomas; Mercer, Joey S.; Martin, Lynne Hazel; Homola, Jeffrey R.; Cabrall, Christopher D.; Brasil, Connie L.

    2011-01-01

    In this paper we discuss the development and evaluation of our prototype technologies and procedures for far-term air traffic control operations with automation for separation assurance, weather avoidance and schedule conformance. Controller-in-the-loop simulations in the Airspace Operations Laboratory at the NASA Ames Research Center in 2010 have shown very promising results. We found the operations to provide high airspace throughput, excellent efficiency and schedule conformance. The simulation also highlighted areas for improvements: Short-term conflict situations sometimes resulted in separation violations, particularly for transitioning aircraft in complex traffic flows. The combination of heavy metering and growing weather resulted in an increased number of aircraft penetrating convective weather cells. To address these shortcomings technologies and procedures have been improved and the operations are being re-evaluated with the same scenarios. In this paper we will first describe the concept and technologies for automating separation assurance, weather avoidance, and schedule conformance. Second, the results from the 2010 simulation will be reviewed. We report human-systems integration aspects, safety and efficiency results as well as airspace throughput, workload, and operational acceptability. Next, improvements will be discussed that were made to address identified shortcomings. We conclude that, with further refinements, air traffic control operations with ground-based automated separation assurance can routinely provide currently unachievable levels of traffic throughput in the en route airspace.

    Erdoğan, M.; Torun, A.; Boyacı, D.

    2012-07-01

    of spatial data quality concepts into developments and application requires existence of conceptual, logical and most importantly physical existence of data model, rules and knowledge of realization in a form of geo-spatial data. The applicable metrics and thresholds are determined on this concrete base. This study discusses application of geo-spatial data quality issues and QA (quality assurance) and QC procedures in the topographic data production. Firstly we introduce MGCP (Multinational Geospatial Co-production Program) data profile of NATO (North Atlantic Treaty Organization) DFDD (DGIWG Feature Data Dictionary), the requirements of data owner, the view of data producers for both data capturing and QC and finally QA to fulfil user needs. Then, our practical and new approach which divides the quality into three phases is introduced. Finally, implementation of our approach to accomplish metrics, measures and thresholds of quality definitions is discussed. In this paper, especially geometry and semantics quality and quality control procedures that can be performed by the producers are discussed. Some applicable best-practices that we experienced on techniques of quality control, defining regulations that define the objectives and data production procedures are given in the final remarks. These quality control procedures should include the visual checks over the source data, captured vector data and printouts, some automatic checks that can be performed by software and some semi-automatic checks by the interaction with quality control personnel. Finally, these quality control procedures should ensure the geometric, semantic, attribution and metadata quality of vector data.

  10. Power plant practices to ensure cable operability

    International Nuclear Information System (INIS)

    This report describes the design, installation, qualification, maintenance, and testing of nuclear power plant cables with regard to continued operability. The report was initiated after questions arose concerning inadvertent abuse of cables during installation at two nuclear power plants. The extent of the damage was not clear and there was a concern as to whether cables, if damaged, would be able to function under accident conditions. This report reviews and discusses installation practices in the industry. The report also discusses currently available troubleshooting and in-situ testing techniques and provides cautions for some cases which may lead to further cable damage. Improved troubleshooting techniques currently under development are also discussed. These techniques may reduce the difficulty of testing while being able to identify cable flaws more definitively. The report finds, in general, that nuclear power plant cables have been relatively trouble-free; however, there is a need for further research and development of troubleshooting techniques which will make cable condition testing easier and more reliable. Also, recommendations for ''good'' installation practices are needed

Methods: The authors’ tests include measurements of output, beam deflection, isotropy, kVp and mAs measurements, quality index, isodose, reproducibility, linearity, depth dose verification, and 3D dose distribution. IC ionization chamber and the UNIDOSE dosimeter were used for the output commissioning. Probe adjuster/ionization chamber holder (PAICH was used to check the mechanical straightness of the probe. For radiation tests, NACP parallel plate chamber, Standard Imaging electrometer, 30 × 30 × 30 cm3 IAEA water phantom, solid water slabs, EDR-2 Films with RIT software, and ionization based survey meters were used. Unfors Xi platinum edition kVp meter was used to measure the kVp and mAs. Results: In mechanical QA test, X-Beam position (-0.09 mm, Y-Beam position (0.01 mm, and radial position (0.11 mm errors were within the tolerance level. Isotropy test with PDA, survey meter, ion chamber, and film measurements also produced results within the specifications. Output measurements with PAICH and external chamber measurements were matched. Beam quality, linearity, and reproducibility values were ascertained at 50KV and 40 µA and found to be within limits. Isodose, 3D dose distribution, transverse, and horizontal profiles showed the good isotropy of the source. Conclusion: The authors’ methodology provides comprehensive commissioning and calibration procedures for the Intrabeam system.

  12. Financial assurances

    International Nuclear Information System (INIS)

    US Ecology is a full service waste management company. The company operates two of the nation's three existing low-level radioactive waste (LLRW) disposal facilities and has prepared and submitted license applications for two new LLRW disposal facilities in California and Nebraska. The issue of financial assurances is an important aspect of site development and operation. Proper financial assurances help to insure that uninterrupted operation, closure and monitoring of a facility will be maintained throughout the project's life. Unfortunately, this aspect of licensing is not like others where you can gauge acceptance by examining approved computer codes, site performance standards or applying specific technical formulas. There is not a standard financial assurance plan. Each site should develop its requirements based upon the conditions of the site, type of design, existing state or federal controls, and realistic assessments of future financial needs. Financial assurances at U.S. Ecology's existing sites in Richland, Washington, and Beatty, Nevada, have been in place for several years and are accomplished in a variety of ways by the use of corporate guarantees, corporate capital funds, third party liability insurance, and post closure/long-term care funds. In addressing financial assurances, one can divide the issue into three areas: Site development/operations, third party damages, and long-term care/cleanup

  13. Practical aspects of commingled IOR operations

    International Nuclear Information System (INIS)

    Decisions to implement commingled improved oil recovery (IOR) techniques are informed by a variety of economic and technical considerations. Many reservoirs have dissimilar qualities and extents of oil saturation depletion and pressurization, which can lead to different resistance levels in IOR operations. This paper presented an outline of critical screening considerations in the implementation of IOR. Issues concerning hydraulic continuity, infilling, solvent washing and lift optimization were examined. Controlled fracturing and the compatibility of different fluids and potential interactions with reservoir rocks were discussed. Various stages in the planning of commingled projects were reviewed. It was noted that IOR and enhanced oil recovery (EOR) in commingled operations can be infeasible if all the participating intervals are not compatible in terms of fluids, production mechanisms, controls, pressures and injectivity. Prospects for commingled IOR are further diminished when options for well interventions or data for individual zones are limited, as well as if the indicated injection pressure exceeds fracture pressure of any of the target reservoirs. It was concluded that successful commingled IOR and enhanced oil recovery (EOR) practices require a thorough understanding of reservoir architecture, fluid and pressure distributions as well as clear insights into the reservoir mechanisms involved. 9 refs., 5 figs

  17. Reactor system safety assurance

    International Nuclear Information System (INIS)

    The philosophy of reactor safety is that design should follow established and conservative engineering practices, there should be safety margins in all modes of plant operation, special systems should be provided for accidents, and safety systems should have redundant components. This philosophy provides ''defense in depth.'' Additionally, the safety of nuclear power plants relies on ''safety systems'' to assure acceptable response to design basis events. Operating experience has shown the need to study plant response to more frequent upset conditions and to account for the influence of operators and non-safety systems on overall performance. Defense in depth is being supplemented by risk and reliability assessment

  1. Quality assurance in conformal radiotherapy: DYNARAD consensus report on practice guidelines

    International Nuclear Information System (INIS)

    Background and purpose: Conformal radiotherapy has only recently been widely implemented. Although not all aspects have yet been adequately proven, it is generally recognized that maintaining a high degree of precision throughout the process is critical to the treatment outcome while the focus for quality assurance and quality improvement will need to concentrate more on human factors, procedures, communication, organization and training. A general consensus document on quality assurance guidelines for institutions that deliver conformal radiotherapy treatments to patients has been elaborated within the framework of the DYNARAD/BIOMED concerted action on conformal radiotherapy. The present paper aims to highlight those issues that were identified as of specific importance to conformal radiotherapy. The work reported here further details this guidance by direct correlation with the issues involved in the special case of conformal radiotherapy. Methods: The DYNARAD document has been drafted in the form of a desktop guide comprising six sets of guidelines and is based on the ESTRO advisory report on 'Quality Assurance in Radiotherapy'. Results and conclusions: The document has been endorsed by the DYNARAD group of institutions. As such it can form the basis for further discussions and enter into the subsequent phase of expanding its consensus basis

  2. Development of a Reliability Program approach to assuring operational nuclear safety

    International Nuclear Information System (INIS)

    A Reliability Program (RP) model based on proven reliability techniques used in other high technology industries is being formulated for potential application in the nuclear power industry. Research findings are discussed. The reliability methods employed under NASA and military direction, commercial airline and related FAA programs were surveyed with several reliability concepts (e.g., quantitative reliability goals, reliability centered maintenance) appearing to be directly transferable. Other tasks in the RP development effort involved the benchmarking and evaluation of the existing nuclear regulations and practices relevant to safety/reliability integration. A review of current risk-dominant issues was also conducted using results from existing probabilistic risk assessment studies. The ongoing RP development tasks have concentrated on defining a RP for the operating phase of a nuclear plant's lifecycle. The RP approach incorporates safety systems risk/reliability analysis and performance monitoring activities with dedicated tasks that integrate these activities with operating, surveillance, and maintenance of the plant. The detection, root-cause evaluation and before-the-fact correction of incipient or actual systems failures as a mechanism for maintaining plant safety is a major objective of the RP

  3. Central Electricity Generating Board use of operational experience feedback to assure safe designs

    International Nuclear Information System (INIS)

    Learning from experience has always been a valuable part of the engineering endeavour. Indeed, those process industries which are continually seeking improvements in their plants regard operating experience as an essential by-product of their main undertaking. When it is carefully recorded and well interpreted, operating experience can have considerable impact on the performance, availability and continuing safety of future plant designs. However, as in all other engineering activities, experience feedback must be carefully planned and executed to ensure that it is cost effective. In order to learn from experience, three things are necessary. First (and obviously) there must be previous relevant experience which has been carefully recorded and stored. Second, there must be an effective system for extracting clearly the lessons available and for targeting them on those who need to know. Third, there must be a willingness for future designers to put these lessons into practice. If any one of these three is missing, then the whole undertaking to learn from experience fails, so it is essential to pay careful attention to all three. This paper outlines how the Central Electricity Generating Board team responsible for building pressurized water reactor units is covering these three aspects. 1 ref., 5 figs

  4. Clinical practice and evaluation of electronic portal imaging device for VMAT quality assurance

    International Nuclear Information System (INIS)

    Volumetric-modulated arc therapy (VMAT) is a novel extension of the intensity-modulated radiation therapy (IMRT) technique, which has brought challenges to dose verification. To perform VMAT pretreatment quality assurance, an electronic portal imaging device (EPID) can be applied. This study's aim was to evaluate EPID performance for VMAT dose verification. First, dosimetric characteristics of EPID were investigated. Then 10 selected VMAT dose plans were measured by EPID with the rotational method. The overall variation of EPID dosimetric characteristics was within 1.4% for VMAT. The film system serving as a conventional tool for verification showed good agreement both with EPID measurements ([94.1 ± 1.5]% with 3 mm/3% criteria) and treatment planning system (TPS) calculations ([97.4 ± 2.8]% with 3 mm/3% criteria). In addition, EPID measurements for VMAT presented good agreement with TPS calculations ([99.1 ± 0.6]% with 3 mm/3% criteria). The EPID system performed the robustness of potential error findings in TPS calculations and the delivery system. This study demonstrated that an EPID system can be used as a reliable and efficient quality assurance tool for VMAT dose verification

The accreditation was renewed in 2003 according the EN ISO/IEC 17025 standard. Accredited fields of testing consist tests of radiation safety and related environmental sampling, gamma spectrometric analyses, radiochemical analyses of tritium, radioactive strontium and transuranic elements in environmental, foodstuff and biological samples, as well as natural radionuclides in water, indoor radon, direct measurement of people and chromosome analysis. In this paper, quality assurance on radiochemical and gamma spectrometric laboratories is discussed. The quality system of STUK is based on ISO standard 9001. The development of a uniform and modern quality system for the whole STUK started in 1997, the regulation was ready in 1999, and was updated in 2003. On the top of STUK quality hierarchy is the quality policy of overall objectives, the second level is the quality manual of the whole STUK followed by the quality manuals of each department. On the base level of the hierarchy there are the laboratory manuals and guides. The standards mentioned above act as guidelines for all work on laboratory level. The principle of continuous improvement is widely applied by performing annual self-assessments and internal and external audits. A quality assurance (QA) programme includes several steps. One of the most important steps is the proficiency of personnel. Good initiation, non-stop training during work and also knowledge of physical and chemical phenomena in analytical procedures are the requirements for first-rate and motivated working. In the QA programme of STUK, these issues are documented, including responsibilities and commitments of each organisational level and employee. The principles and the philosophy of these topics are discussed. Since the environmental levels of radioactivity are

  8. Safety in nuclear power plant operation, including commissioning and decommissioning. A code of practice

    International Nuclear Information System (INIS)

    Safe operation of a nuclear power plant postulates satisfactory siting, design, construction and commissioning, together with proper management and operation of the plant. This Code of Practice deals with the safety aspects of management, commissioning, operation and decommissioning of the plant. It forms part of the Agency's programme, referred to as the NUSS programme, for establishing Codes of Practice and Safety Guides relating to land-based stationary thermal neutron power plants. It has been prepared for the use of those responsible for the operation of stationary nuclear power plants, the main function of which is the generation of electrical and/or thermal power, and for the use of those responsible for regulating the operation of such plants. It is not intended for application to reactors used solely for experimental or research purposes. The provisions in the Code are designed to provide assurance that operational activities are carried out without undue radiological hazard to the general public and to persons on the site. It should be understood that the provisions in the Code set forth minimum requirements which shall be met in order to achieve safe operation of a nuclear power plant

    Process management (PM) is a valuable method for the systematic analysis and structural optimisation of the quality and safety of clinical treatment. PM requires a high motivation and willingness to implement changes of both employees and management. Definition of quality indicators is required to systematically measure the quality of the specified processes. One way to represent comparable quality results is the use of quality indicators of the external quality assurance in accordance with Sect. 137 SGB V—a method which the Federal Joint Committee (GBA) and the institutions commissioned by the GBA have employed and consistently enhanced for more than ten years. Information on the quality of inpatient treatment is available for 30 defined subjects throughout Germany. The combination of specified processes with quality indicators is beneficial for the information of employees. A process-based indicator dashboard provides essential information about the treatment process. These can be used for process analysis. In a continuous consideration of these indicator results values can be determined and errors will be remedied quickly. If due consideration is given to these indicators, they can be used for benchmarking to identify potential process improvements. PMID:25523849

  10. Quality assurance in radiotherapy

    International Nuclear Information System (INIS)

    Good radiotherapy results and safety of treatment require the radiation to be optimally applied to a specified target area and the correct dose. According to international recommendations, the average uncertainty in therapeutic dose should not exceed 5%. The need for high precision in therapeutic dose requires quality assurance covering the entire radiotherapy process. Besides the physical and technical characteristics of the therapy equipment, quality assurance must include all radiotherapy equipment and procedures that are significant for the correct magnitude and precision of application of the therapeutic dose. The duties and responsibilities pertaining to various stages of treatment must also be precisely defined. These requirements may be best implemented through a quality system. The general requirements for supervision and quality assurance of medical radiation apparatus are prescribed in section 40 of the Radiation Act (592/1991, amendment 1142/1998) and in sections 18 and 32 of the Decree of the Ministry of Social Affairs and Health on the medical use of radiation (423/2000). Guide ST 2.2 imposes requirements on structural radiation shielding of radiotherapy equipment and the premises in which it is used, and on warning and safety arrangements. Guide ST 1.1 sets out the general safety principles for radiation practices and regulatory control procedure for the use of radiation. Guide ST 1.6 provides general requirements for operational measures in the use of radiation. This Guide sets out the duties of responsible parties (the party running a radiation practice) in respect of arranging and maintaining radiotherapy quality assurance. The principles set out in this Guide and Guide ST 6.3 may be applied to radionuclide therapy

    2010-07-01

    Pipeline transmission systems have been designed traditionally using steady state simulations. Steady state simulation provided sufficient values for simple systems, but is limited in dealing with surges in flow rates, loss of facilities and facility operation. A dynamic approach is required to test the capacity of a system for various fluids. This paper investigated the use of transient analysis of liquid pipelines in order to improve the design of these pipelines and to achieve operational benefits. The transient method and its use are discussed. Dynamic analysis was applied to the Keystone Pipeline Project. The purpose of the study was first to determine the system capacity and data for transportation of Heavy DilBit, and then to implement batch transportation of a volume of synthetic crude oil. It was found that the use of transient modeling in design and operational assessment of a liquid pipeline ensures system capability, control, safety and integrity.

  16. Towards Run-time Assurance of Advanced Propulsion Algorithms

    2014-01-01

    This paper covers the motivation and rationale for investigating the application of run-time assurance methods as a potential means of providing safety assurance for advanced propulsion control systems. Certification is becoming increasingly infeasible for such systems using current verification practices. Run-time assurance systems hold the promise of certifying these advanced systems by continuously monitoring the state of the feedback system during operation and reverting to a simpler, certified system if anomalous behavior is detected. The discussion will also cover initial efforts underway to apply a run-time assurance framework to NASA's model-based engine control approach. Preliminary experimental results are presented and discussed.

  20. Quality assurance/quality control training for plant operation and maintenance

    International Nuclear Information System (INIS)

    One of the most important tasks during the period of plant operation is to ensure the effectiveness of the information links inside the utility and the nuclear industry. To make use of all information, experience and knowledge as well as to make sure that instructions are followed, it is necessary to provide rules, instructions and training for all people involved. QA/QC-training for plant operation and maintenance must deliver a consciousness of men in a way that e.g. instructions or procedures are followed strictly, the management is informed about deviations and mistakes, alterations are carried out with approval only, safety systems are kept integer all the time and interfaces are linked together properly. By means of examples about staff organization, control room and shift rules, work permit procedures and use of an information feedback system QA measures shall be demonstrated. (orig.)

    The SLDPF is responsible for the capture, quality monitoring processing, accounting, and shipment of Spacelab and/or Attached Shuttle Payloads (ASP) telemetry data to various user facilities. Expert systems will aid in the performance of the quality assurance and data accounting functions of the two SLDPF functional elements: the Spacelab Input Processing System (SIPS) and the Spacelab Output Processing System (SOPS). Prototypes were developed for each as independent efforts. The SIPS Knowledge System Prototype (KSP) used the commercial shell OPS5+ on an IBM PC/AT; the SOPS Expert System Prototype used the expert system shell CLIPS implemented on a Macintosh personal computer. Both prototypes emulate the duties of the respective QA/DA analysts based upon analyst input and predetermined mission criteria parameters, and recommended instructions and decisions governing the reprocessing, release, or holding for further analysis of data. These prototypes demonstrated feasibility and high potential for operational systems. Increase in productivity, decrease of tedium, consistency, concise historial records, and a training tool for new analyses were the principal advantages. An operational configuration, taking advantage of the SLDPF network capabilities, is under development with the expert systems being installed on SUN workstations. This new configuration in conjunction with the potential of the expert systems will enhance the efficiency, in both time and quality, of the SLDPF's release of Spacelab/AST data products.

  4. International conference on safe decommissioning for nuclear activities: Assuring the safe termination of practices involving radioactive materials. Contributed papers

    International Nuclear Information System (INIS)

    Thousands of operations involving the use of radioactive substances will end during the current century. While there is considerable regulatory experience in the 'front end' of the regulatory system for practices, the experience at the back end is more limited as fewer practices have actually been terminated. When a practice is terminated because the facility has reached the end of its useful life, action has to betaken to ensure the safe shutdown of the facility and allow the removal of regulatory controls. There are many issues involved in the safe termination of practices. These include setting criteria for the release of material and sites from regulatory control; determining the suitability of the various options for decommissioning nuclear facilities, managing the waste and material released from control (recycling, reuse or disposal), and the eventual remediation of the site. Some countries have put in place regulatory infrastructures and have developed programmes to manage the associated decommissioning and remediation activities. Other countries are at the stage of assessing what is involved in terminating such practices. The purpose of this Conference is to foster an information exchange on the safe an orderly termination of practices that involve the use of radioactive substances, including both decommissioning and environmental remediation, and to promote improved coherence internationally on strategies and criteria for the safe termination of practices

  6. Modern safety practices in operating nuclear power plants in Spain

    International Nuclear Information System (INIS)

    At the end of the Nuclear Power Plant design, we were faced in Spain with several challenges to transfer the knowledge and developments acquired during this stage to the operation and maintenance practices. Two aspects were particularly relevant: the transfer of the design and licensing bases to the operation documentation and to the design of plant modifications and to use the results of the probabilistic safety analysis (PSA) for improving the operational and maintenance practices. Both concepts have been developed and applied to the NPPs in Spain. The first has been carried out trough a plant configuration management and the second by the development of specific software which has allowed to use the models and results of the overall plant PSA for practical maintenance and operation applications. This paper describes the work performed in both areas, as examples of the connection between the design and operation of NPPs, which leads to a systematic safety improvement. Several safety practices which are being implemented in Spanish nuclear power plants have been selected as an example of some current methods which systematically improve operational safety.

    International Nuclear Information System (INIS)

    This Safety Guide was prepared as part of the Agency's programme, referred to as the NUSS programme, for establishing Codes of Practice and Safety Guides relating to nuclear power plants. It supplements the IAEA Code of Practice on Quality Assurance for Safety in Nuclear Power Plants (IAEA Safety Series No.50-C-QA), which requires that for each nuclear power plant a system for the generation, identification, collection, indexing, filing, storing, maintenance and disposition of quality assurance records shall be established and executed in accordance with written procedures and instructions. The purpose of this Safety Guide is to provide assistance in the establishment and operation of such a system. An orderly established and maintained records system is considered to be part of the means of providing a basis for an appropriate level of confidence that the activities which affect the quality of a nuclear power plant have been performed in accordance with the specific requirements and that the required quality has been achieved and is maintained

  8. Guidebook on good practice in the management of uranium mining and mill operations and the preparation for their closure

    International Nuclear Information System (INIS)

    Over the past fifty years the uranium industry has moved from a labor-intensive industry to a 'high-tech' and capital intensive industry. Organization of knowledge, manpower and material had to change to meet the demands of several stakeholders inherent to any project and to constantly adapt to technological innovations. Today, the mission of a uranium operation is not only to make a profit while selling yellow cake to electrical power stations but also to address issues regarding safety, health, environment and demands of the regulators and the public and assure the sustainability of the operations. Good mining practice begins with the proper planning and forecasting from the discovery of a deposit to decommissioning of a mine. This report describes and defines what is considered as good practice in the various activities of a mining operation and provides an overview of the management of a single operation. As technologies are progressing rapidly in the mining industry, and as this industry is transitional, this report emphasizes the importance of training employees at all levels of the organization. The statement on good practices for the various activities of a mining operation will be useful for organizations which are planning to open new mines or intend to modernize ongoing operations. Practical examples are given in the case of histories for four different countries. The objective of this publication is not to provide strict rules on the application of good practice but to give general guidelines that can be consulted and used in many different countries

    2014-06-01

    In this paper we introduce High Assurance SPIRAL to solve the last mile problem for the synthesis of high assurance implementations of controllers for vehicular systems that are executed in today's and future embedded and high performance embedded system processors. High Assurance SPIRAL is a scalable methodology to translate a high level specification of a high assurance controller into a highly resource-efficient, platform-adapted, verified control software implementation for a given platform in a language like C or C++. High Assurance SPIRAL proves that the implementation is equivalent to the specification written in the control engineer's domain language. Our approach scales to problems involving floating-point calculations and provides highly optimized synthesized code. It is possible to estimate the available headroom to enable assurance/performance trade-offs under real-time constraints, and enables the synthesis of multiple implementation variants to make attacks harder. At the core of High Assurance SPIRAL is the Hybrid Control Operator Language (HCOL) that leverages advanced mathematical constructs expressing the controller specification to provide high quality translation capabilities. Combined with a verified/certified compiler, High Assurance SPIRAL provides a comprehensive complete solution to the efficient synthesis of verifiable high assurance controllers. We demonstrate High Assurance SPIRALs capability by co-synthesizing proofs and implementations for attack detection and sensor spoofing algorithms and deploy the code as ROS nodes on the Landshark unmanned ground vehicle and on a Synthetic Car in a real-time simulator.

  13. International and intranational co-operation on practical improvements in plant operation and safety practices

    International Nuclear Information System (INIS)

    A principal recommendation contained in the Kemeny Commission's report on the nuclear accident at Three Mile Island (TMI) was that the nuclear industry needed an effective system for learning from operating experience. The US Nuclear Regulatory Commission (NRC) incorporated a similar recommendation into its principal document on responses to the accident at TMI. A comprehensive system for analysing and recording operating experience systematically is now in its third year. Called the Significant Events Evaluation and Information Network (SEE-IN) programme, the system was developed jointly by the Institute of Nuclear Power Operations (INPO) and the Nuclear Safety Analysis Center (NSAC). The system is centred at INPO and NSAC provides technical support on generic issues and on low probability events that might have large consequences (such potential events are deemed ''significant'' even though the actual event might be benign). The frequency of significant events in the period 1980-81 ranges from none in two years to seven in two years. The fraction that has the larger number of significant events is also noted to have a greater degree of recurrence of similar events in the same operating unit and tends to include those units that have slower and less complete response to identified remedies. Based on screening and review of events, it is estimated that there have been about 500 operating events in US reactors since 1960 that would now be classified as significant. There have also been approximately 50 unit-years of extended outages in excess of time required for refuelling, a large part of which can be associated with one or more significant events. (author)

  14. Waste Management Quality Assurance Plan

    International Nuclear Information System (INIS)

    The WMG QAP is an integral part of a management system designed to ensure that WMG activities are planned, performed, documented, and verified in a manner that assures a quality product. A quality product is one that meets all waste acceptance criteria, conforms to all permit and regulatory requirements, and is accepted at the offsite treatment, storage, and disposal facility. In addition to internal processes, this QA Plan identifies WMG processes providing oversight and assurance to line management that waste is managed according to all federal, state, and local requirements for waste generator areas. A variety of quality assurance activities are integral to managing waste. These QA functions have been identified in the relevant procedures and in subsequent sections of this plan. The WMG QAP defines the requirements of the WMG quality assurance program. These requirements are derived from Department of Energy (DOE) Order 414.1C, Quality Assurance, Contractor Requirements Document, the LBNL Operating and Assurance Program Plan (OAP), and other applicable environmental compliance documents. The QAP and all associated WMG policies and procedures are periodically reviewed and revised, as necessary, to implement corrective actions, and to reflect changes that have occurred in regulations, requirements, or practices as a result of feedback on work performed or lessons learned from other organizations. The provisions of this QAP and its implementing documents apply to quality-affecting activities performed by the WMG; WMG personnel, contractors, and vendors; and personnel from other associated LBNL organizations, except where such contractors, vendors, or organizations are governed by their own WMG-approved QA programs

  15. Evaluation and development of process operators' working practices

    International Nuclear Information System (INIS)

    The practical aim of our research was to enhance the safety of NPP operations through the development of competencies and design of man-machine interfaces, and through contributing to safety management by providing better human reliability assessment methods. A prerequisite for achievements in these issues is understanding of the nature of the work in the NPP. We have focused on the comprehension of the control room operators' core task. With the premise of the intentional nature of human activity we have developed a new contextual approach for the analysis of activity in real-life situations. It is called the Contextual Analysis of Working Practices (CAWP). Habit of action is a central concept, and we have proposed a practical way to identify habits of action through the analysis of the actors' ways of taking account of the possibilities and constraints of the situation and of using available resources. We have carried out empirical studies in two nuclear power plants and executed four series of simulator experiments. This has taken place in close co-operation with the simulator trainers and experts of the plants, and nearly all control room crews of these plants have been involved. The central result of this work is the development of the CAWP methodology. With the help of it we have identified differences in the NPP operators' working practices that seem to have relevance for the adequacy of process control. We have also found indications of the significance of working practices for a situationally adaptive use of information aids in the control room, which ought to be verified later. Our research method has been adapted for a routinely used simulator training method. Moreover, the methodology has been applied as a tool in the validation of control room information aids, and incorporated into a new dynamic human reliability method (not discussed here). (orig.)

    Mckenzie, Alan

    A common feature of the Radiotherapy Centres where there have been major accidents involving incorrect radiotherapy treatment is that they did not operate good Quality Assurance systems. A Quality Assurance system is sometimes called a Quality Management system, and it is designed to give assurance that quality standards are being met. One of the "spin offs" from operating a Quality Management system is that it reduces the likelihood of a radiotherapy accident. A detailed account of how to set up a quality system in radiotherapy has been given in an ESTRO booklet.2

  18. Operator priming and generalization of practice in adults' simple arithmetic.

    Science.gov (United States)

    Chen, Yalin; Campbell, Jamie I D

    2016-04-01

    There is a renewed debate about whether educated adults solve simple addition problems (e.g., 2 + 3) by direct fact retrieval or by fast, automatic counting-based procedures. Recent research testing adults' simple addition and multiplication showed that a 150-ms preview of the operator (+ or ×) facilitated addition, but not multiplication, suggesting that a general addition procedure was primed by the + sign. In Experiment 1 (n = 36), we applied this operator-priming paradigm to rule-based problems (0 + N = N, 1 × N = N, 0 × N = 0) and 1 + N problems with N ranging from 0 to 9. For the rule-based problems, we found both operator-preview facilitation and generalization of practice (e.g., practicing 0 + 3 sped up unpracticed 0 + 8), the latter being a signature of procedure use; however, we also found operator-preview facilitation for 1 + N in the absence of generalization, which implies the 1 + N problems were solved by fact retrieval but nonetheless were facilitated by an operator preview. Thus, the operator preview effect does not discriminate procedure use from fact retrieval. Experiment 2 (n = 36) investigated whether a population with advanced mathematical training-engineering and computer science students-would show generalization of practice for nonrule-based simple addition problems (e.g., 1 + 4, 4 + 7). The 0 + N problems again presented generalization, whereas no nonzero problem type did; but all nonzero problems sped up when the identical problems were retested, as predicted by item-specific fact retrieval. The results pose a strong challenge to the generality of the proposal that skilled adults' simple addition is based on fast procedural algorithms, and instead support a fact-retrieval model of fast addition performance.

    Pain assessment is crucial to achieving optimal pain management in children. Pain that is insufficiently controlled can have extensive short- and long-term repercussions. Many studies continue to report that children experience unnecessary post-operative pain when they are in hospital. The purpose of this literature review was to explore post-operative pain assessment practices used by children's nurses. A literature search of databases was undertaken and inclusion criteria identified. Four themes emerged: pain assessment tools; behavioural cues; documentation; and communication between child, parent/carer and nurse. The findings showed that pain assessment tools were inadequately used, that children's behavioural cues were misinterpreted, and that there was inconsistency in the documentation of pain scores and in communication about pain scores between children, parent/carer and nurse. Addressing the key issues identified from the articles reviewed can help improve nursing practice and care. PMID:27266751

  20. Quality management and quality assurance

    International Nuclear Information System (INIS)

    The main common difficulties are presented found in the implementation of effective Quality Management and Quality Assurance Programmes, based on the recommendations of the IAEA International Nuclear Safety Advisory Group, the information collected by the IAEA experts participating in its meetings, and the results of the IAEA Operational Safety Review Team missions. The difficulties were identified in several areas. The most relevant root causes can be characterized as lack of understanding of quality principles and difficulty in implementation by the responsible management. The IAEA programme is described attempting to provide advice and support in the implementation of an effective quality programme through a number of activities including: preparation of practical guidelines, training programmes for management personnel, assistance in building up qualified manpower, and promoting the quest for excellence through the exchange of experience in the implementation of effective Quality Management and Quality Assurance Programmes in nuclear power plants with good performance records.

  12. Quality assurance for the safe transport of radioactive material

    International Nuclear Information System (INIS)

    All activities related to the safe transport of radioactive material should be covered by a quality assurance programme. This publication recognizes that a single transport operation often involves several different organizations, each having specific responsibilities. Hence, it is unlikely that the operation will be covered by a single quality assurance programme. Each quality assurance programme should be tailored to the specific organizational structure for which the programme is prepared, with account taken of the particular transport activities of that organization and the interfaces with other organizations. The aim of this publication is to give a detailed interpretation of what must be done by whom to produce a quality assurance programme for radioactive material transport. This publication provides guidance on methods and practical examples to develop QA programmes for the safe transport of radioactive material. It provides information on how to develop the programme, the standards and the common features of a QA programme

    2012-01-01

    This paper proposes a cyber security modeling and simulation roadmap to enhance mission assurance governance and establish risk reduction processes within constrained budgets. The term mission assurance stems from risk management work by Carnegie Mellon's Software Engineering Institute in the late 19905. By 2010, the Defense Information Systems Agency revised its cyber strategy and established the Program Executive Officer-Mission Assurance. This highlights a shift from simply protecting data to balancing risk and begins a necessary dialogue to establish a cyber security roadmap. The Military Operations Research Society has recommended a cyber community of practice, recognizing there are too few professionals having both cyber and analytic experience. The authors characterize the limited body of knowledge in this symbiotic relationship. This paper identifies operational and research requirements for mission assurance M&S supporting defense and homeland security. M&S techniques are needed for enterprise oversight of cyber investments, test and evaluation, policy, training, and analysis.

    With rising grid interconnections of solar photovoltaic (PV) systems, greater attention is being trained on lifecycle performance, reliability, and project economics. Expected to meet production thresholds over a 20-30 year timeframe, PV plants require a steady diet of operations and maintenance (O&M) oversight to meet contractual terms. However, industry best practices are only just beginning to emerge, and O&M budgets—given the arrangement of the solar project value chain—appear to vary widely. Based on insights from in-depth interviews and survey research, this paper presents an overview of the utility-scale PV O&M budgeting process along with guiding rationales, before detailing perspectives on current plant upkeep activities and price points largely in the U.S. It concludes by pondering potential opportunities for improving upon existing O&M budgeting approaches in ways that can benefi t the industry at-large.

  19. Assurance by transient book-keeping in operation that the components of a nuclear system remain permanently within their design conditions

    International Nuclear Information System (INIS)

    The transient book-keeping in French PWR nuclear plants was made to comply with French safety regulations. The selected method consists in collecting the transients, comparing them with the design transients and deducting them from the design list. It is therefore important that the design list represents correctly the future operation of the plant. In fact, a survey of operational conditions led to the modification of the design list so that it takes in account all the transients brought to light by operating experience. This operating experience highlights the main physical parameters and the most loaded points of the primary circuit which allows the operator or designer to minimise the fatigue damage. This leads to modification of operational procedures and design. Examples illustrate these conclusions: make up line behaviour, problems during the test period, heat up cool down of the reactor and permanent fluctuations. The transient book-keeping and subsequent operational experience improve the knowledge of plants' behaviour and consequently the assurance of safe operation. (author)

  1. Summary report of the Department of Energy, Division of Operational and Environmental Safety: Quality Assurance Programs 9 through 12

    International Nuclear Information System (INIS)

    Analaytical Laboratories which provide environmental monitoring data for assessment of radioactive contamination, under the Department of Energy (DOE) Contract, were requested to participate in a Quality Assurance Program. The Environmental Measurement Laboratory (EML) was asked to prepare intercomparison samples for radionuclide analysis of soil, water, air filters, tissue ash and vegetation ash for distribution to the Analytical Laboratories. Samples were collected in the environment of DOE facilities, since only water and air samples could be conveniently spiked. A set of 6 to 8 samples is distributed quarterly to 34 laboratories. EML performed multiple analyses on the samples, however, the results are considered intercomparisons, not standards. The program is summarized, and data for Quality Assessment Programs (QAP) 9 through 12 are evaluated

    This study emphasized the need for considering flow assurance for producing oil and gas, particularly in high cost areas such as deepwater. Phase behaviour studies, sticking propensities, and interfacial interactions have been investigated in many laboratory studies using asphaltenes, wax, hydrates, organic and inorganic scale, and even diamondoids. However, the spatial variation of reservoir fluids has received little attention, despite the fact that it is one of the most important factors affecting flow assurance. This issue was difficult to address in a systematic way in the past because of cost constraints. Today, reservoir fluid variation and flow assurance can be considered at the outset of a project given the technological advances in downhole fluid analysis. This study described the origins of reservoir fluid compositional variations and the controversies surrounding them. It also described the indispensable chemical analytical technology. The impact of these reservoir fluid compositional variations on flow assurance considerations was also discussed. A methodology that accounts for these variations at the outset in flow assurance evaluation was also presented.

  5. Reliability of lead-calcium automotive batteries in practical operations

    Science.gov (United States)

    Burghoff, H.-G.; Richter, G.

    In order to reach a statistically sound conclusion on the suitability of maintenance-free, lead-calcium automotive batteries for practical operations, the failure behaviour of such batteries has been observed in a large-scale experiment carried out by Mercedes Benz AG and Robert Bosch GmbH in different climatic zones of North America. The results show that the average failure behaviour is not significantly different to that of batteries from other manufacturers using other grid alloy systems and operated under otherwise identical conditions; the cumulative failure probability after 30 months is 17%. The principal causes of failure are: (i) early failure: transport damage, filling errors, and short-circuits due to the outer plates being pushed up during plate-block assembly (manufacturing defect); (ii) statistical failure: short-circuits due to growth of positive plates caused by a reduction in the mechanical strength of the cast positive grid as a result of corrosion; (iii) late failure due to an increased occurrence of short-circuits, especially frequent in outer cell facing the engine of the vehicle (subjected to high temperature), and to defects caused by capacity decay. As expected, the batteries exhibit extremely low water loss in each cell. The poor cyclical performance of stationary batteries, caused by acid stratification and well-known from laboratory tests, has no detrimental effect on the batteries in use. After a thorough analysis of the corrosion process, the battery manufacturer changed the grid alloy and the method of its production, and thus limited the corrosion problem with cast lead-calcium grids and with it the possibility of plate growth. The mathematical methods used in this study, and in particular the characteristic factors derived from them, have proven useful for assessing the suitability of automotive batteries.

    International Nuclear Information System (INIS)

    Even the best QA plan and its successful execution during construction of a typical fusion machine will produce hardware that is inoperative for some fraction of time. Operating a machine with its hardware out of tolerance, with respect to the specifications, does produce data which is the goal of the experiment. However, a majority of such data are difficult to interpret and may not contribute to understanding the behavior of the experiment. In addition, few fusion machines just operate. The majority of the machines are in the process of being rebuilt and/or added to as they operate. These modifications can keep an otherwise operational machine from running. To insure quality in operation of TMX-U, the authors employ a series of QA procedures. They start with technical milestones, schedules, and budgets that are all negotiated with DOE. Within that framework they implement a total management scheme which, in addition to normal schedule and budget controls, includes: detailed experimental run plans, definition of machine configuration required to accomplish the run plan, subsystem work-ups, instrument calibration, verification of subsystem operation, and repetition of standard physics plasma parameters. All of these activities must be completed before taking data for the experimental run plan. If a subsystem is found out of tolerance, a decision must be made either to delay operation and fix the problem or to continue on a contingency-run plan which should still produce the data relevant to the project milestones. In this presentation those QA procedures for TMX-U operations that are applied to minimize the cost and time required to achieve the technical objectives are discussed

    International Nuclear Information System (INIS)

    Quality checks are essential to assure production of high quality plants and to have end-users confidence. Quality standards require the establishment of suitable tests to maintain quality control. The choice of explant source, freedom of the donor plant from viruses, disease causing fungi, bacteria, viroids, phytoplasmas, vigour and conformity of the variety, and elimination of somaclonal variants are critical for maintaining plant quality. Variety identification by proper labeling at all stages is essential to ensure varietal identity. (author)

  2. The assurance management program for the Nova laser fusion project

    International Nuclear Information System (INIS)

    In a well managed project, Quality Assurance is an integral part of the management activities performed on a daily basis. Management assures successful performance within budget and on schedule by using all the good business, scientific, engineering, quality assurance, and safety practices available. Quality assurance and safety practices employed on Nova are put in perspective by integrating them into the overall function of good project management. The Inertial Confinement Fusion (ICF) approach is explained in general terms. The laser ICF and magnetic fusion facilities are significantly different in that the laser system is used solely as a highly reliable energy source for performing plasma physics experiments related to fusion target development; by contrast, magnetic fusion facilities are themselves the experiments. The Nova project consists of a 10-beam, 74 cm aperture neodymium-glass laser experimental facility which is being constructed by the Lawrence Livermore National Laboratory (LLNL) for the U.S. Department of Energy. Nova has a total estimated cost of $176M and will become operational in the Fall of 1984. The Nova laser will be used as the high energy driver for studying the regime of ignition for ICF. The Nova assurance management program was developed using the quality assurance (QA) approach first implemented at LLNL in early 1978. The LLNL QA program is described as an introduction to the Nova assurance management program. The Nova system is described pictorially through the Nova configuration, subsystems and major components, interjecting the QA techniques which are being pragmatically used to assure the successful completion of the project

  13. The path to impact of operational research on tuberculosis control policies and practices in Indonesia

    Directory of Open Access Journals (Sweden)

    Ari Probandari

    2016-02-01

    Full Text Available Background: Operational research is currently one of the pillars of the global strategy to control tuberculosis. Indonesia initiated capacity building for operational research on tuberculosis over the last decade. Although publication of the research in peer-reviewed journals is an important indicator for measuring the success of this endeavor, the influence of operational research on policy and practices is considered even more important. However, little is known about the process by which operational research influences tuberculosis control policy and practices. Objective: We aimed to investigate the influence of operational research on tuberculosis control policy and practice in Indonesia between 2004 and 2014. Design: Using a qualitative study design, we conducted in-depth interviews of 50 researchers and 30 policy makers/program managers and performed document reviews. Transcripts of these interviews were evaluated while applying content analysis. Results: Operational research contributed to tuberculosis control policy and practice improvements, including development of new policies, introduction of new practices, and reinforcement of current program policies and practices. However, most of these developments had limited sustainability. The path from the dissemination of research results and recommendations to policy and practice changes was long and complex. The skills, interests, and political power of researchers and policy makers, as well as health system response, could influence the process. Conclusions: Operational research contributed to improving tuberculosis control policy and practices. A systematic approach to improve the sustainability of the impact of operational research should be explored.

  15. Assessment of the Effectiveness of Operational and Regulatory Systems in Nuclear and Radiation Practices

    International Nuclear Information System (INIS)

    Upon choosing a nuclear option and during the implementation or operation of the project, frequently two main questions are asked are relevant to the effectiveness of both the project management or the operating system of the project and the regulatory authority or system that is responsible of performing the regulatory functions relevant to assuring the state about the safety and securing of the whole project and the security of the nuclear material involved as well as the safety and security of the environment. In the present work the main issues that can be adopted as indicators of the effectiveness of both the operational system as well as the regulatory system are discussed. Moreover, some issues concerning the role of the workers in the project as well as on site dosimetry and their relation to the effectiveness of the project management or the regulatory body are also discussed.

  16. Are patent medicine vendors effective agents in malaria control? Using lot quality assurance sampling to assess quality of practice in Jigawa, Nigeria.

    Directory of Open Access Journals (Sweden)

    Sima Berendes

    Full Text Available BACKGROUND: Patent medicine vendors (PMV provide antimalarial treatment and care throughout Sub-Saharan Africa, and can play an important role in the fight against malaria. Their close-to-client infrastructure could enable lifesaving artemisinin-based combination therapy (ACT to reach patients in time. However, systematic assessments of drug sellers' performance quality are crucial if their role is to be managed within the health system. Lot quality assurance sampling (LQAS could be an efficient method to monitor and evaluate PMV practice, but has so far never been used for this purpose. METHODS: In support of the Nigeria Malaria Booster Program we assessed PMV practices in three Senatorial Districts (SDs of Jigawa, Nigeria. A two-stage LQAS assessed whether at least 80% of PMV stores in SDs used national treatment guidelines. Acceptable sampling errors were set in consultation with government officials (alpha and beta <0.10. The hypergeometric formula determined sample sizes and cut-off values for SDs. A structured assessment tool identified high and low performing SDs for quality of care indicators. FINDINGS: Drug vendors performed poorly in all SDs of Jigawa for all indicators. For example, all SDs failed for stocking and selling first-line antimalarials. PMV sold no longer recommended antimalarials, such as Chloroquine, Sulfadoxine-Pyrimethamine and oral Artesunate monotherapy. Most PMV were ignorant of and lacked training about new treatment guidelines that had endorsed ACTs as first-line treatment for uncomplicated malaria. CONCLUSION: There is urgent need to regularly monitor and improve the availability and quality of malaria treatment provided by medicine sellers in Nigeria; the irrational use of antimalarials in the ACT era revealed in this study bears a high risk of economic loss, death and development of drug resistance. LQAS has been shown to be a suitable method for monitoring malaria-related indicators among PMV, and should be

  20. Influence of quality assurance on company management

    International Nuclear Information System (INIS)

    The implementation of quality assurance programmes affects the management of companies as it imposes certain constraints on their operation and requires a number of additional tasks to be performed. It is difficult to make a qualitative study of these constraints and their effects on cost, lead times and quality, and even more difficult to quantify them. The company must allocate the human and financial resources required to implement the programme. Like other expenditures, these must be properly managed to ensure that they are utilized most effectively. In order to assess the consequences of a quality assurance programme for the management of a company, a clear distinction must be drawn between that which relates to equipment quality (i.e. characteristics and performance) and that which results from the quality assurance of this same equipment. The constraints which quality assurance places on the performance of certain company activities are examined, and an attempt is made to point out the differences with regard to the good management practices of companies skilled in manufacturing quality installations not subject to nuclear safety requirements. The author describes a management method for these complementary tasks aimed at obtaining maximum effectiveness. The review has been limited to design verification, audits, monitoring of manufacturing and installation processes, training and certification of personnel, methods of handling non-conforming items and corrective action to be taken, and, finally, records. A number of examples are given to demonstrate the effectiveness of quality assurance in obtaining the quality of equipment and systems required to ensure the safety of nuclear power facilities

    Mobile calcination and cementation unit MESA 1 was designed and built by UJV Rez in cooperation with many enterprises, mainly with the Kralovopolske Strojirny Brno. This facility for direct fixation of liquid radioactive wastes was experimentally tested using model non-radioactive solutions and model and actual wastes from the Jaslovske Bohunice nuclear power plant. The calciner was run in trial operation at the Kralovopolske SAtrojirny Brno. A total of 1.3 m3 of model solutions was processed into 180 kg of calcinate. The fixation of the calcinate in cement, the times of solidification and of hardening and the moisture content of concrete blocks were studied. The application was also tested of the calciner in drying ion exchangers from WWER-440 prior to their bituminization. Following the despatch of the cementation module to the Chernobyl nuclear power plant, the direct calcination module was tested at Dukovany together with an auxiliary module which makes possible self-contained calciner operation. Model non-radioactive solutions from the Dukovany nuclear power plant were treated containing H3BO3 and NaNO3 as main components. The usability in actual conditions of the mobile calcination and cementation unit for radioactive wastes was tested in a total of about 70 operating hours. (E.S.). 2 figs., 2 refs

  11. Quality control and quality assurance of nuclear analytical techniques. Thematic planning of QC/QA in technical co-operations. Report of the external participants

    International Nuclear Information System (INIS)

    In areas of trade, health, safety, and environmental protection users of a laboratory's analytical results, for example by governments and private institutions, are increasingly requiring demonstrable proof of the reliability and credibility of the laboratory's analytical results using internationally accepted standards. This is so that the products and the decisions based on these laboratory results will be accepted in the respective national and international communities. These requirements are being imposed, for example by the European Community and others, for products to be imported and can be a significant barrier to trade, especially for developing nations. In addition to this there is a growing need for these laboratories to operate efficiently and effectively to reduce internal waste, to provide reports on time in an economical manner and to become self supporting. The need for change is global and this proposal is for the Agency to pursue a thematic plan for the implementation of quality assurance as partners in development with the selected laboratories using nuclear analytical techniques. This report describes a model project for this thematic approach to confirm the models immediate benefits as well as facilitating long-term sustainability of member states' laboratories. The model is thematic in that it is also applicable to all other projects for which the credibility and reliability of the results of a laboratory's processes and results must be demonstrated. This model project provides a cost effective approach for protecting the Agency's investment in these laboratories and strengthening the ability of these national institutions to define, organize, and manage the application of nuclear technology in their respective countries. This pilot project consists of (1) determining the general levels of knowledge and application of quality assurance principles (as delineated in ISO Guide 25) in the responding laboratories; (2) selecting a trail group of

Recently, a great number of similar projects is under development in Baltic Sea, inter alia in Polish EEZ, natural conditions of which vary from the North Sea significantly. In this paper, those differences are described together with some solutions to problems thereby arising.

  17. Regulatory inspection of the implementation of quality assurance programmes

    International Nuclear Information System (INIS)

    This manual provides guidance to Member States in the organization and performance of their regulatory inspection functions regarding the implementation of nuclear power plant quality assurance programmes. It addresses the interface between, and is consistent with, the IAEA Nuclear Safety Standards (NUSS programme) documents on quality assurance and governmental organization. The manual offers a practical model and examples for performing regulatory inspections to ensure that the quality assurance programme is operating satisfactorily in the siting, design, manufacturing, construction, commissioning, operation and decommissioning of nuclear power plants. The primary objective is to confirm that the licensee has the capability to manage and control the effective performance of all quality assurance responsibilities during all phases of a nuclear power project. The guidance provided through this manual for proper establishment and execution of the regulatory inspections helps to enforce the effective implementation of the quality assurance programme as a management control system that the nuclear industry should establish and use in attaining the safety and reliability objectives for nuclear installations. This enforcement action by national regulatory bodies and the emphasis on the purposes and advantages of quality assurance as an important management tool integrated within the total project task have been recommended by the IAEA International Nuclear Safety Advisory Group (INSAG). The primary intended users of this manual are the management personnel and high level staff from regulatory bodies but it will also be helpful to management personnel from nuclear utilities and vendors. They all are inevitable partners in a nuclear power project and this document offers all of them valuable information on the better accomplishment of quality assurance activities to ensure the common objective of safe and reliable nuclear power production

  19. Code on the safety of nuclear power plants: Quality assurance

    International Nuclear Information System (INIS)

    This revised Code provides the principles and objectives for the establishment and implementation of quality assurance programmes applied to both the overall and each of the constituent activities associated with a nuclear power plant project. The quality assurance principles enumerated in the present Code can be usefully applied to nuclear facilities other than nuclear power plants. The quality assurance programme encompasses: (1) the activities that are necessary to achieve the appropriate quality of the respective item or service; and (2) the activities that are necessary for verifying that the required quality is achieved and that objective evidence is produced to that effect. Quality assurance is an essential aspect of good management and the quality assurance programme is the main management tool for a disciplined approach to all activities affecting quality, including, where appropriate, verification that each task has been satisfactorily performed and that necessary corrective actions have been implemented. The principles and objectives provided by the Code are applicable by all those responsible for the nuclear power plant, by plant designers, suppliers, architect-engineers, plant constructors, plant operators and other organizations participating in activities affecting quality. The Code is a revision of the previous Code of Practice (1978) on the same subject of interest to regulatory bodies and experts in quality assurance for design, siting and operation of nuclear power plants. Contents: Definitions; 1. Introduction; 2. Quality assurance programmes; 3. Organization; 4. Document control; 5. Design control; 6. Procurement control; 7. Control of items; 8. Process control; 9.

    Lang, R.; Spezio, M.

    - C based and big endian. The presence of byte swap issues that might not have been identified in the required software changes was very real and can be difficult to find. The ability to have test designs that would exercise all major functions and operations was invaluable to assure that critical operations and tools would operate as they had since first operational use. With the longevity of the mission also came the realization that the original ISAT team would not be the people working on the ISAT regression testing. The ability to have access to all original test designs and test results identified in the regression test suite greatly improved the ability to identify not only the expected system behavior, but also the actual behavior with the old architecture. So in summary, this paper will discuss the importance, practicality, and results achieved by having a well-defined regression test available to assure the New Horizons Mission Operations Control system continues to meet its functional requirements to support the mission objectives.

  1. Practical Use of Operation Data in the Process Industry

    Science.gov (United States)

    Kano, Manabu

    This paper aims to reveal real problems in the process industry and introduce recent development to solve such problems from the viewpoint of effective use of operation data. Two topics are discussed: virtual sensor and process control. First, in order to clarify the present state and problems, a part of our recent questionnaire survey of process control is quoted. It is emphasized that maintenance is a key issue not only for soft-sensors but also for controllers. Then, new techniques are explained. The first one is correlation-based just-in-time modeling (CoJIT), which can realize higher prediction performance than conventional methods and simplify model maintenance. The second is extended fictitious reference iterative tuning (E-FRIT), which can realize data-driven PID control parameter tuning without process modeling. The great usefulness of these techniques are demonstrated through their industrial applications.

  2. Theory and Practice in ICRF Antennas for Long Pulse Operation

    International Nuclear Information System (INIS)

    Long plasma discharges on the Tore Supra (TS) tokamak were extended in 2004 towards higher powers and plasma densities by combined Lower Hybrid (LH) and Ion Cyclotron Range of Frequencies (ICRF) waves. RF pulses of 20 s x 8 MW and 60 s x 4 MW were produced. TS is equipped with 3 ICRF antennas, whose front faces are ready for CW operation. This paper reports on their behaviour over high power long pulses, as observed with infrared (IR) thermography and calorimetric measurements. Edge parasitic losses, although modest, are concentrated on a small surface and can raise surface temperatures close to operational limits. A complex hot spot pattern was revealed with at least 3 physical processes involved: convected power, electron acceleration in the LH near field, and a RF-specific phenomenon compatible with RF sheaths. LH coupling was also perturbed in the antenna shadow. This was attributed to RF-induced DC ExB0 convection. This motivated sheath modelling in two directions. First, the 2D topology of RF potentials was investigated in relation with the RF current distribution over the antenna, via a Green's function formalism and full-wave calculation using the ICANT code. In front of phased arrays of straps, convective cells were interpreted using the RF current profiles of strip line theory. Another class of convective cells, specific to antenna box corners, was evidenced for the first time. Within 1D sheath models assuming independent flux tubes, RF and rectified DC potentials are proportional. 2D fluid models couple nearby flux tubes via transverse polarisation currents. Unexpectedly this does not necessarily smooth RF potential maps. Peak DC potentials can even be enhanced. The experience gained on TS and the numerical tools are valuable for designing steady state high power antennas for next step devices. General rules to reduce RF potentials as well as concrete design options are discussed. (authors)

  3. Knowledge degradation within routine operation practices in TRR: Lessons learned

    International Nuclear Information System (INIS)

    Full text: During shift operation of Tehran Research Reactor (TRR) in June 2001, a series of malfunctions and abnormalities occurred which led to a complete stop of reactor for full investigation of why and how and other pertaining questions. Although the initiating event is believed to be a stuck rod problem which is investigated elsewhere, but in the course of investigation, as it was found by fact finding committee, human behaviour and degradation of knowledge of operating personnel found to be of a major role in propagation of errors. In this paper, only human factors and its role creating this event would be discussed. Among all human factors two main categories are distinguished in this study. One category is comprised of those which have a general nature and has to do with peculiarities of cultural aspects of the society and may equally contribute to other problems of different natures as well. The other one is comprised of factors specific to the TRR and conditions pertaining to this system. Both categories are discussed and analyzed in this paper in detail. Some of them which are discussed in this paper are enumerated as the following: I. General factors: 1. economic incentives, 2. carelessness, 3. lack of curiosity, 4. lack of questioning, 5. burden of administrative rule over scientific views. II. Factors specific to TRR system and environment: 1. lack of independent supervision, 2. poor systematic training, 3. misinterpretation of checklists, 4. lack of access to all necessary documents, 5. persisting to continue a shift while there is a malfunction, 6. poor bookkeeping, 7. lack of clarity on job descriptions, 8. lack of proper maintenance, 9. lack of incentive to attract professionals. In short, we believe emphasizing on human aspects and promoting a sound environment is as equally important as mere academic training and well-established programs. (author)

  8. The practical aspects of discontinuation of nucler plant operation

    International Nuclear Information System (INIS)

    On the basis of the experience gathered so far in the sixteen discontinuation projects in Germany - according to the authors - it is possible to formulate some generally valid discovered facts, techniques and procedures. The extensive experience shows that take-down of a nuclear plant involves only low radiation dosage for the personnel, only a manageable amount of radioactive waste, and can be carried out under reasonable economic boundary conditions. The necessary decision of choice between 'immediate take-down' and 'take-down after safe encapsulation' cannot be made in general terms, but depends on the specific boundary conditions of the plant. This includes the personnel situation, the local infra-structure, possibilities, for final repository and, above all, financial considerations. Future requirements comprise above all intelligent dismantling techniques, in the sense that established procedures should function as dependably as possible even in unfavourable environment such as high radiation intensity and great depth of water, and if they fail, it must be possible to schedule repairs. The assertion that discontinuation of a nuclear power station requires extensive remotely controlled manipulating facilities, has not been confirmed - such facilities are chiefly confined to operations under water. Particularly with regard to the final repository problems, it is important to reduce the amount of radioactive waste material. For this purpose it is urgently necessary to develop very effective decontamination procedures, for example chemical decontamination of the primary circulation, or blasting of plant components with steel grit.

  10. Grading of quality assurance requirements

    International Nuclear Information System (INIS)

    The present Manual provides guidance and illustrative examples for applying a method by which graded quality assurance requirements may be determined and adapted to the items and services of a nuclear power plant in conformance with the requirements of the IAEA Nuclear Safety Standards (NUSS) Code and Safety Guides on quality assurance. The Manual replaces the previous publication IAEA-TECDOC-303 on the same subject. Various methods of grading quality assurance are available in a number of Member States. During the development of the present Manual it was not considered practical to attempt to resolve the differences between those methods and it was preferred to identify and benefit from the good practices available in all the methods. The method presented in this Manual deals with the aspects of management, documentation, control, verification and administration which affect quality. 1 fig., 4 tabs

  11. Measurement quality assurance

    International Nuclear Information System (INIS)

    The quality of a radiation protection program can be no better than the quality of the measurements made to support it. In many cases, that quality is unknown and is merely implied on the basis of a calibration of a measuring instrument. If that calibration is inappropriate or is performed improperly, the measurement result will be inaccurate and misleading. Assurance of measurement quality can be achieved if appropriate procedures are followed, including periodic quality control actions that demonstrate adequate performance. Several national measurement quality assurance (MQA) programs are operational or under development in specific areas. They employ secondary standards laboratories that provide a high-quality link between the National Bureau of Standards and measurements made at the field use level. The procedures followed by these secondary laboratories to achieve MQA will be described, as well as plans for similar future programs. A growing general national interest in quality assurance, combined with strong specific motivations for MQA in the area of ionizing radiation, will provide continued demand for appropriate national programs. Such programs must, however, employ procedures that are cost effective and must be developed with participation by all affected parties

  12. The Practice of a Quality Assurance System in Open and Distance Learning: A case study at Universitas Terbuka Indonesia (The Indonesia Open University

    Directory of Open Access Journals (Sweden)

    Tian Belawati

    2007-03-01

    Full Text Available Quality assurance for distance higher education is one of the main concerns among institutions and stakeholders today. This paper examines the experiences of Universitas Terbuka (UT, which has initiated and implemented an innovative strategy of quality assurance (QA for continuous improvement. The credo of the UT quality assurance system is "We write what we do. We do what we write. We check. We improve continuously!" Implementing a quality management system at the UT, a mega-university with a student body of more than a quarter of a million and which involved a network of participating institutions and regional centres, was a formidable task to accomplish. To achieve its lofty goal, UT adopted and contextualised the draft of the Asian Association of Open Universities (AAOU QA Framework to launch its own quality assurance program. This has taken a great deal of commitment and participation of all staff involved. QA at the UT required systematic and step-by-step processes, including development of the QA framework and job manuals, raising awareness and commitment amongst all staff involved, internal assessment, and integration of QA programs into the university's annual action plans, external assessment and benchmarking. This paper concludes that quality assurance must be developed as institutional policy and strategy for continuous improvement.

  13. Quality Interaction Between Mission Assurance and Project Team Members

    Science.gov (United States)

    Kwong-Fu, Helenann H.; Wilson, Robert K.

    2006-01-01

    Mission Assurance independent assessments started during the development cycle and continued through post launch operations. In operations, Health and Safety of the Observatory is of utmost importance. Therefore, Mission Assurance must ensure requirements compliance and focus on process improvements required across the operational systems including new/modified products, tools, and procedures. The deployment of the interactive model involves three objectives: Team member Interaction, Good Root Cause Analysis Practices, and Risk Assessment to avoid reoccurrences. In applying this model, we use a metric based measurement process and was found to have the most significant effect, which points to the importance of focuses on a combination of root cause analysis and risk approaches allowing the engineers the ability to prioritize and quantify their corrective actions based on a well-defined set of root cause definitions (i.e. closure criteria for problem reports), success criteria and risk rating definitions.

  20. New source performance standards for industrial boilers. Volume 2. Review of industry operating practices

    Energy Technology Data Exchange (ETDEWEB)

    Bryan, R.J.; Weisenberg, I.J.; Wilson, K.

    1980-09-01

    The applicability is evaluated of several possible versions of a revised New Source Performance Standards (NSPS) for industrial boilers to boilers that are operated according to typical industry practices. A survey of operating practices is presented, and it is concluded that an NSPS that includes too high a percent removal requirement for SO/sub 2/ (90%) might be excessively costly and cause operating problems for the industrial operator. More field evaluations of low excess air and low Btu gasification are required to validate these techniques for pollution control under industrial boiler operating conditions. The cost of two small boilers with no SO/sub 2/ controls was less than one large boiler of twice the capacity with SO/sub 2/ controls. The annual cost of operating and maintaining the control system accounted for the difference.

    This text introduces the fundamental concepts and practical simulation techniques for modelling different aspects of operating systems to study their general behaviour and their performance.The approaches applied are object-oriented modelling and the process interaction approach to simulation. Most other books on performance modelling use only analytical approaches, and very few apply these modelling concepts to the study of operating systems. Thus, a key feature of the book is that it concentrates on the study of operating systems using practical simulation techniques. In addition, the book i

  7. Operations & Maintenance Best Practices - A Guide to Achieving Operational Efficiency (Release 3)

    Energy Technology Data Exchange (ETDEWEB)

    Sullivan, Greg; Pugh, Ray; Melendez, Aldo P.; Hunt, W. D.

    2010-08-04

    This guide highlights operations and maintenance programs targeting energy and water efficiency that are estimated to save 5% to 20% on energy bills without a significant capital investment. The purpose of this guide is to provide you, the Operations and Maintenance (O&M)/Energy manager and practitioner, with useful information about O&M management, technologies, energy and water efficiency, and cost-reduction approaches. To make this guide useful and to reflect your needs and concerns, the authors met with O&M and Energy managers via Federal Energy Management Program (FEMP) workshops. In addition, the authors conducted extensive literature searches and contacted numerous vendors and industry experts. The information and case studies that appear in this guide resulted from these activities. It needs to be stated at the outset that this guide is designed to provide information on effective O&M as it applies to systems and equipment typically found at Federal facilities. This guide is not designed to provide the reader with step-by-step procedures for performing O&M on any specific piece of equipment. Rather, this guide first directs the user to the manufacturer's specifications and recommendations. In no way should the recommendations in this guide be used in place of manufacturer's recommendations. The recommendations in this guide are designed to supplement those of the manufacturer, or, as is all too often the case, provide guidance for systems and equipment for which all technical documentation has been lost. As a rule, this guide will first defer to the manufacturer's recommendations on equipment operation and maintenance.

  8. Nuclear power plant safety and reliability assurance

    International Nuclear Information System (INIS)

    The philosophy of nuclear power plant safety is that design should follow established and conservative engineering practices, there should be safety margins in all modes of plant operations, special systems should be provided for response to accidents, and safety systems should have redundant components. This philosophy provides ''defense in depth.'' In recent years, with the accumulation of operating experience and the unexpected complexity of the present generation of light water reactors, the defense in depth philosophy has been supplemented by risk and reliability assessments. Reliability assurance programs based on these probabilistic engineering assessments provide a means of integrating design review, maintenance, testing, replacement of parts, failure reporting, and corrective action, so that the protection of the plant and the public can be systematically ensured

  15. The successful Chief Executive Officer understands quality assurance

    International Nuclear Information System (INIS)

    The successful Chief Executive Officer (CEO) will have recognized the benefits of, and have implemented, a total quality assurance program. The quality assurance program will be adequately defined in policies and procedures such that managers and supervisors of each organizational element understand their primary and supporting roles in carrying out an effective quality assurance program. The traditional practice of having all quality assurance activities reside in a quality assurance organization will have been cast aside. Instead, the quality assurance activities necessary to achieve and assure the quality of the desired end product will have been defined and assigned to responsible organization elements. The quality assurance organization's primary role will be to define the total quality assurance program, insure that the achieving and assuring functions are assigned in policies and procedures, conduct training necessary to have management and supervisors understand the total quality assurance program, measure the effectiveness of the program and feedback measurement data for improvements in the program. The successful CEO will have implemented a quality assurance program that provides for a graded approach for application of the program based upon the importance of the intended use of the product or service. The successful CEO will rely heavily on the scheduled progress reports and assessments to measure the pulse of his organization's successes and improvement needs. This paper will describe suggested approaches for the Quality Assurance Manager to implement a quality assurance program which results in his corporation's CEO being a supporter of and a driving force in the implementation of the quality assurance program

  19. Review of quality assurance criteria for nuclear power plants in Japan

    International Nuclear Information System (INIS)

    The present quality assurance guide of Japan Electric Association, JEAG-4101, was prepared in 1972 for the purpose of establishing the safety functions, insuring the public and employees' health, improving operational reliability and maintaining power supply. This guide reflects the state of nuclear power generation of those days. It stands on the point of recognition that quality assurance is controlled by the builders of plants. However, its contents are very simple, and do not mention the concrete means and methods of the items to be conducted, though the items are clear. Since then, international cooperation has progressed in nuclear power industries, and it may be natural that quality assurance criteria are eagerly required to be internationally adaptable. Thus it was decided to do the work for revising JEAG-4101 considering the matching with the Cord of Practice of IAEA. The scope is the quality assurance activity in design, manufacture, installation and trial operation, while operation practice is omitted because it is covered by the present ''security regulations''. The contents of the revised draft include the general description, quality assurance program, organization, document control, design control, procurement control, material and equipment control, manufacture and installation control, inspection and testing control, disqualification control and audit.

  5. Practical aspects of steam injection processes: A handbook for independent operators

    Energy Technology Data Exchange (ETDEWEB)

    Sarathi, P.S.; Olsen, D.K.

    1992-10-01

    More than 80% of the total steam injection process operating costs are for the production of steam and the operation of surface and subsurface equipment. The proper design and operation of the surface equipment is of critical importance to the success of any steam injection operation. However, the published monographs on thermal recovery have attached very little importance to this aspect of thermal oil recovery; hence, a definite need exists for a comprehensive manual that places emphasis on steam injection field practices and problems. This handbook is an attempt to fulfill this need. This handbook explores the concept behind steam injection processes and discusses the information required to evaluate, design, and implement these processes in the field. The emphasis is on operational aspects and those factors that affect the technology and economics of oil recovery by steam. The first four chapters describe the screening criteria, engineering, and economics of steam injection operation as well as discussion of the steam injection fundamentals. The next four chapters begin by considering the treatment of the water used to generate steam and discuss in considerable detail the design, operation and problems of steam generations, distribution and steam quality determination. The subsurface aspects of steamflood operations are addressed in chapters 9 through 12. These include thermal well completion and cementing practices, insulated tubulars, and lifting equipment. The next two chapters are devoted to subsurface operational problems encountered with the use of steam. Briefly described in chapters 15 and 16 are the steam injection process surface production facilities, problems and practices. Chapter 17 discusses the importance of monitoring in a steam injection project. The environmental laws and issues of importance to steam injection operation are outlined in chapter 18.

  10. Quality assurance in individual monitoring

    International Nuclear Information System (INIS)

    Measurement and assessment of radiation dose to the individual radiation worker, called 'Individual monitoring', is one of the most important aspects of radiation protection. International Commission on Radiation Protection (ICRP-75) has outlined three main objectives of personal monitoring viz assessment of the effectively equivalent dose to demonstrate compliance with managerial and regulatory requirements; to contribute to control of operation and design of facilities and in case of accidental overexposure, to provide valuable information for the initiation and support of any health surveillance and treatment. To meet these objectives, it is essential that the measurements are reliable and accurate as defined by National and International Standards. This requires setting up of well defined internal as well as external quality assurance protocol in the individual monitoring program. External quality assurance program is meant to provide a reliable and qualitative as well as quantitative assessment of the service provided by the service provider. In India, individual monitoring is based on CaSO4:Dy based TLD badge and the task of conducting external quality assurance (QA) is being performed by RP and AD, Bhabha Atomic Research Centre. The paper presents the methodology of Quality assurance, Performance evaluation standards and criteria. It discusses the results and important observations of last few QA cycles conducted for all the TLD Labs. The quality assurance check has indicated that the performance of all the Labs is satisfactory in accordance with ANSI as well as Trumpet curve methodology. It provided feedback on further improvements in the quality

  11. Concepts of nuclear quality assurance

    International Nuclear Information System (INIS)

    While the safety record of the nuclear industry continues to be excellent, the forced outage rates for recent years continue to be 15% or more. Quality assurance, therefore, needs to be applied not only to nuclear safety matters, but to the goals of increased productivity and reduced construction and operating costs. Broadening the application of the general concept of quality assurance in this way leads to the introduction of reliability technology. The total activity might better be called reliability assurance. That effective quality assurance systems do pay off is described by examples from the utility industry, from a manufacturer of instruments and systems and from the experience of Westinghouse Electric Company's manufacturing divisions. The special situation of applying quality assurance to nuclear fuel is discussed. Problems include the lack of a fully developed regulatory policy in this area, incomplete understanding of the mechanism for pellet-clad interaction failures, incomplete access to manufacturers design and process information, inability to make desirable changes on a timely basis and inadequate feedback of irradiation experience.

  15. OSART programme highlights 1993-1994. Operational safety practices in nuclear power plants

    International Nuclear Information System (INIS)

    This report continues the practice of summarizing mission results so that all the aspects of OSART missions, Pre-OSART missions and good practices are to be found in one volume. For the first time it includes results of follow-up visits. Attempts have been made in this report to highlight the most significant findings whilst retaining as much of the vital background information as possible. This report is in four parts: Part I summarizes the most significant observations made during the missions and follow-up visits during 1993-1994; Part II, in chronological order, is an overview of the major strengths and opportunities for improvement identified during each OSART mission and summaries of follow-up visits performed during the period; Part III lists good practices that were identified during 1993 and 1994; and Part IV presents the recently developed OSART mission results (OSMIR) database. Each part of the report is intended for different levels in operating and regulatory organizations but not exclusively so. Part I is primarily to the executive management level; Part II to middle managers; and Parts III and IV to those involved in operational experience feedback. Because of widely different plant designs, operating and management styles, cultural practices, and other factors affecting plant operations, no OSART findings were applicable to all of the plants visited in 1993 and 1994. Individual findings varied considerably in scope and significance. However, the findings do reflect some common strengths and opportunities for improvement. 4 tabs

  16. Requirement Assurance: A Verification Process

    Science.gov (United States)

    Alexander, Michael G.

    2011-01-01

    Requirement Assurance is an act of requirement verification which assures the stakeholder or customer that a product requirement has produced its "as realized product" and has been verified with conclusive evidence. Product requirement verification answers the question, "did the product meet the stated specification, performance, or design documentation?". In order to ensure the system was built correctly, the practicing system engineer must verify each product requirement using verification methods of inspection, analysis, demonstration, or test. The products of these methods are the "verification artifacts" or "closure artifacts" which are the objective evidence needed to prove the product requirements meet the verification success criteria. Institutional direction is given to the System Engineer in NPR 7123.1A NASA Systems Engineering Processes and Requirements with regards to the requirement verification process. In response, the verification methodology offered in this report meets both the institutional process and requirement verification best practices.

    CERN Document Server

    CERN. Geneva

    2015-01-01

    FESA is a framework used by 100+ developers at CERN to design and implement the real-time software used to control the accelerators. Each new version must be tested and qualified to ensure that no backward compatibility issues have been introduced and that there is no major bug which might prevent accelerator operations. Our quality assurance approach is based on code review and a two-level testing process. The first level is made of unit-test (Python unittest & Google tests for C++). The second level consists of integration tests running on an isolated test environment. We also use a continuous integration service (Bamboo) to ensure the tests are executed periodically and the bugs caught early. In the presentation, we will explain the reasons why we took this approach, the results and some thoughts on the pros and cons.

  2. Comparison of the inspection practices in relation to the control room operator and shift supervisor licenses

    International Nuclear Information System (INIS)

    The CNRA believes that safety inspections are a major element in the regulatory authority's efforts to ensure the safe operation of nuclear facilities. Considering the importance of these issues, the Committee has established a special Working Group on Inspection Practices (WGIP). The purpose of WGIP, is to facilitate the exchange of information and experience related to regulatory safety inspections between CNRA Member countries In 1996, members of WGIP discussed various ways in which regulatory inspectors look at and evaluate how licenses are given to control room operators and shift supervisors in the Member countries. As a result of these discussions it was proposed to put together a short comparison report on this issue. The CNRA approved work on this at its annual meeting that year. This CNRA/WGIP study concentrates on the regulatory inspection of control room operator competence and authorisation. As noted in the text, fourteen Member countries supplied input by responding to the questionnaire. This report presents a comparison of inspection practices in participating OECD countries relating to control room operator and shift supervisor licenses. The report has been derived from answers to a questionnaire on the basis of guidance given in Appendix 1.1 with the detailed answers being given in Appendix 1. Key questions for this comparison were 'What are the regulatory or licensee requirements for holding and up-keeping a license or authorisation' and 'How does the regulatory body inspect the training and competence of shift teams and individual operators'. The main conclusion from the comparison is that the general practice within the participating countries for ensuring the competence of operators is broadly similar although regulatory practices differ markedly. For example, the regulatory bodies in some countries are actively involved in the examination and licensing process of individual operators whereas other regulatory bodies

Methods: According to the characteristics of hybrid interventional operation for multiple injuries, the basic construction of the hybrid operating room improved, the hybrid operation team was organized, and the administrative system as well as the working program were established. The green channel for rescuing patients with multiple injuries was set up. The cooperative behavior during interventional treatment for multiple injuries was specified. Results: The coordination and working efficiency of physicians, nurses, technicians and anesthetists were well improved. The qualified rate of lamina flow administration reached 100%. The success rate of the rescue of multiple injuries was increased. Conclusion: As one-stop complex interventional operation for multiple injuries is a new technique, there is no integrated administration system. Therefore, the establishment of standardized management of one-stop complex interventional operation is of great significance in guiding clinical practice. (authors)

  4. Reliability assurance programme guidebook for advanced light water reactors

    International Nuclear Information System (INIS)

    To facilitate the implementation of reliability assurance programmes (RAP) within future advanced reactor programmes and to ensure that the next generation of commercial nuclear reactors achieves the very high levels of safety, reliability and economy which are expected of them, in 1996, the International Atomic Energy Agency (IAEA) established a task to develop a guidebook for reliability assurance programmes. The draft RAP guidebook was prepared by an expert consultant and was reviewed/modified at an Advisory Group meeting (7-10 April 1997) and at a consults meeting (7-10 October 1997). The programme for the RAP guidebook was reported to and guided by the Technical Working Group on Advanced Technologies for Light Water Reactors (TWG-LWR). This guidebook will demonstrate how the designers and operators of future commercial nuclear plants can exploit the risk, reliability and availability engineering methods and techniques developed over the past two decades to augment existing design and operational nuclear plant decision-making capabilities. This guidebook is intended to provide the necessary understanding, insights and examples of RAP management systems and processes from which a future user can derive his own plant specific reliability assurance programmes. The RAP guidebook is intended to augment, not replace, specific reliability assurance requirements defined by the utility requirements documents and by individual nuclear steam supply system (NSSS) designers. This guidebook draws from utility experience gained during implementation of reliability and availability improvement and risk based management programmes to provide both written and diagrammatic 'how to' guidance which can be followed to assure conformance with the specific requirements outlined by utility requirements documents and in the development of a practical and effective plant specific RAP in any IAEA Member State

  5. OSART mission highlights 1989-1990: Operational safety practices in nuclear power plants

    International Nuclear Information System (INIS)

    The IAEA Operational Safety Review Team (OSART) programme provides advice and assistance to Member States in enhancing the operational safety of nuclear power plants. OSART reviews are available to all countries with nuclear power plants in operation or approaching operation. Most of these countries have participated in the programme, by hosting one or more OSART missions or by making experts available to participate in missions. Careful design and high quality of construction are prerequisites for a safe nuclear power plant. However, a plant's safety depends ultimately on the ability and conscientiousness of the operating personnel and on their tools and work methods. OSART missions assess a facility's operational practices in comparison with those used successfully in other countries, and exchange, at the working level, ideas for promoting safety. Both the plants reviewed and the organizations providing experts have benefited from the programme. The observations of the OSART members are documented in technical notes which are then used as source material for the official OSART Report submitted to the government of the host country. The technical notes contain recommendations for improvements and descriptions of recommendable good practices. The same notes have been used to compile the present summary report which is intended for wide distribution to all organizations constructing, operating or regulating nuclear power plants. This report is the fourth in a series following IAEA-TECDOC-458, IAEA-TECDOC-497 and IAEA-TECDOC-570 and covers the period June 1989 to December 1990. Reference is also made to a summary report of Pre-OSART missions, which is in preparation. In addition, a report presenting OSART Good Practices has been published (IAEA-TECDOC-605)

It provides for the planning, performance, reporting and follow-up of the quality assurance audit activity. It defines in general terms the responsibilities of the auditing and audited organizations. The Guide also covers auditing in the context of supplier evaluation; it does not include inspection for the sole purpose of process control or product acceptance. Like the Code, the present Guide was prepared as part of the IAEA's programme, referred to as the NUSS programme, for establishing Codes of Practice and Safety Guides relating to land-based stationary thermal neutron power plants

  7. Regulatory control of the use of contractors by operating organizations. Peer discussions on regulatory practices

    International Nuclear Information System (INIS)

    This report arises from the eighth series of peer discussions on regulatory practices entitled 'Regulatory control of the use of contractors by operating organizations'. Senior regulators from 19 Member States participated in two peer group discussions in March 2000 and May 2000. This report gives an account of the outcomes of these meetings and of practical suggestions put forward by senior regulators. These suggestions do not necessarily reflect the views of the governments of the nominating Member States, the organizations they belong to, or the International Atomic Energy Agency. The objective of this document is to share experience between regulatory bodies and provide practical suggestions for controlling the use of contractors and subcontractors by the operating organizations during all stages, especially operation, of a nuclear power plant, so as to ensure that the quality of work and services delivered is commensurate with the safety importance of the activities and that these are carried out in a manner that will not adversely affect the safe or reliable operation of the facility. These documented practical suggestions and experiences are the result of a series of peer discussions at the IAEA in 2000. It is considered that the manner in which control is exercised, and the various challenges connected to this control, are highly dependent upon the legislative framework, maturity of the nuclear programme, the size of the national nuclear industry and the culture in each country. The report is structured so that it covers the subject matter under the following main headings: Legal Provisions, Regulatory Strategy and Requirements; Regulatory Approaches for Controlling the Use of Contractors; Types of Contracts; Practical Suggestions

    As space mission software systems become larger and more complex, it is increasingly important for the software assurance effort to have the ability to effectively assess both the artifacts produced during software system development and the development process itself. Conceptually, assurance is a straightforward idea - it is the result of activities carried out by an organization independent of the software developers to better inform project management of potential technical and programmatic risks, and thus increase management's confidence in the decisions they ultimately make. In practice, effective assurance for large, complex systems often entails assessing large, complex software artifacts (e.g., requirements specifications, architectural descriptions) as well as substantial amounts of unstructured information (e.g., anomaly reports resulting from testing activities during development). In such an environment, assurance engineers can benefit greatly from appropriate tool support. In order to do so, an assurance organization will need accurate and timely information on the tool support available for various types of assurance activities. In this paper, we investigate the current use of tool support for assurance organizations within NASA, and describe on-going work at JPL for providing assurance organizations with the information about tools they need to use them effectively.

  10. Safe Operation of Nuclear Power Plants. Code of Practice and Technical Appendices

    International Nuclear Information System (INIS)

    This book is in two parts. The first is a Code of Practice for the Safe Operation of Nuclear Power Plants and the second part is a compilation of technical appendices. Its object is to give information and illustrative examples that would be helpful in implementing the Code of Practice. This second part, although published under the same cover, is not part of the Code. Safe operation of a nuclear power plant postulates suitable siting and proper design, construction and management of the plant. Under the present Code of Practice for the Safe Operation of Nuclear Power Plants, those intending to operate the plant are recommended to prepare documentation which would deal with its operation and include safety analyses. The documentation in question would be reviewed by a regulatory body independent of the operating organization; operation would be authorized on the understanding that it would comply with limits and conditions designed to ensure safety. The Code may be subject to revision in the light of experience. The Appendices provide additional information together with some examples relating to certain topics dealt with in the Code; it must be emphasized that they are included as examples for information only and are not part of any recommendation. Purpose and scope: The recommendations in the Code are designed to protect the general public and the operating personnel from radiation hazards, and the Code forms part of the Agency's Safety Standards. The Code, which should be used in conjunction with the Agency's other Safety Standards, provides guidance and information to persons and authorities responsible for the operation of stationary nuclear power plants whose main function is the generation of thermal, mechanical or electrical power; it is not intended to apply to reactors used solely for experimental or research purposes. It sets forth minimum requirements which, it is believed, in the light of experience, must be met in order to achieve safe operation of a

  11. Quality assurance for nuclear power stations in Japan

    International Nuclear Information System (INIS)

    The quality assurance programmes of the Japanese industry show some special features, both in the nuclear field and in non-nuclear technology. Among them e.g. the meticulous care given by Japanese workers to their work and duties, and the high training level and skill of employees in the development and other departments. Another important feature is the common practice of Japanese firms, to guarantee lifetime employment to workers and employees. The quality assurance programme for nuclear power plants covers such aspects as basic design features, detailed planning and construction, fuel element fabrication, basic research, licensing and operation. The responsibility for efficient execution of the programmes lies with the administration, the utilities, the suppliers, as well as all other contractors to a project. The tasks to be fulfilled by organisations, firms, etc., are briefly explained. (orig./HSCH)

  12. OSART mission highlights 2001-2003. Operational safety practices in nuclear power plants

    International Nuclear Information System (INIS)

    The IAEA Operational Safety Review Team (OSART) programme provides advice and assistance to Member States in enhancing the operational safety of nuclear power plants (NPPs). Careful design and high quality of construction are prerequisites for a safe nuclear power plant. However, a plant's safety depends ultimately on the ability and conscientiousness of the operating personnel and on the plant programmes, processes and working methods. An OSART mission compares a facility's operational performance with IAEA Safety Standards and proven good international practices. The OSART reviews are available to all countries with nuclear power plants in operation, but also approaching operation, commissioning or in earlier stages of construction (Pre-OSART). Most countries have participated in the programme by hosting one or more OSART missions or by making experts available to participate in missions. Operational safety missions can also be part of the design review missions of nuclear power plants and are known as Safety Review Missions (SRMs). Teams that review only a few specific areas or a specific issue are called Expert missions. Follow-up visits are a standard part of the OSART programme and are conducted between 12 to 18 months following the OSART mission. This report continues the practice of summarizing mission results so that all the aspects of OSART missions, Pre-OSART missions and OSART good practices are to be found in one document. It also includes the results of follow-up visits. Attempts have been made in this report to highlight the most significant findings while retaining as much of the vital background information as possible. This report is in three parts: Part I summarizes the most significant observations made during the missions and follow-up visits between 2001 and 2003; Part II, in chronological order, reviews the major strengths and opportunities for improvement identified during each OSART mission and summarizes the follow-up visits performed

    Full Text Available The goal is to understand the views of users with type 2 diabetes about their participation in the operating groups and the impact of self-care practices. This is a qualitative descriptive- exploratory held in three basic health units of the sanitary district east of Belo Horizonte and involved the participation of 18 users in 2011. The speeches of the users were analyzed based on content analysis, identifying the categories: exchange of experience, education for self- care, assessment of user participation in the operative groups, Feelings and links between professionals and users. It was noted that the operational groups provided the construction of knowledge through listening, reflection and questioning of reality where the user identified the importance of knowledge about diet, physical activity and treatment. We found that health actions implemented through the operational groups encourage users to think about your lifestyle, characterized as a tool in health education from the perspective of promotion, prevention and control.

    Science.gov (United States)

    Burnett, M.

    2009-12-01

    The technical mechanisms for exchange of Earth Observation resources (data, services, clients, applications, etc.) are becoming mature. These mechanisms allow for new and innovative solutions to be assembled from components and services from a diverse group of sources. Standards, technologies and best practices are coalescing, allowing the Earth Observation community to more fully leverage web services, and the principles of a Service Oriented Architecture. NASA’s ECHO program provides a Service Oriented Architecture infrastructure. Through ECHO, users can discover and access over 110 million Earth Observation resources provided by NASA. ECHO has been operational for six years and the ECHO program has many practical experiences in fielding and operating SOA infrastructure for mission critical systems. This presentation will address the real impacts of providing operational SOA infrastructure for the Earth Observing community. There are significant impacts in the areas of performance, robustness, evolvability and usability. Of all of these important operational concerns, we will focus on the identification and mitigation of security risks in an operational SOA infrastructure environment.

    2007-10-01

    Until the establishment of the PREM Bank (Perron Rotary Express Milk Bank) donor human milk banking had not occurred in Australia for the past 20 years. In re-establishing donor human milk banking in Australia, the focus of the PREM Bank has been to develop a formal and consistent approach to safety and quality in processing during the operation of the human milk bank. There is currently no existing legislation in Australia that specifically regulates the operation of donor human milk banks. For this reason the PREM Bank has utilised existing and internationally recognised management practices for managing hazards during food production. These tools (specifically HACCP) have been used to guide the development of Standard Operating Procedures and Good Manufacturing Practice for the screening of donors and processing of donor human milk. Donor screening procedures are consistent with those recommended by other human milk banks operating internationally, and also consistent with the requirements for blood and tissue donation in Australia. Controlled documentation and record keep requirements have also been developed that allow complete traceability from individual donation to individual feed dispensed to recipient and maintain a record of all processing and storage conditions. These operational requirements have been developed to reduce any risk associated with feeding pasteurised donor human milk to hospitalised preterm or ill infants to acceptable levels. PMID:17913402

  19. Enhanced design, operation and maintenance practices for a longer plant service life

    International Nuclear Information System (INIS)

    Plant service life problems have been under detailed investigation in France and the experience acquired by our company over the past 25 years in the design, construction and maintenance of Pressurized Water Reactors has contributed to develop skills, equipment and capabilities available for efficient plant aging management and component service life extension. The service life of a nuclear power plant is deeply dependant of the provisions made during the design stage, directly linked to good operating conditions and adequate maintenance practices. This paper presents the importance of these three steps (design, operation and maintenance) for plant service life concern. (author)

  1. Comprehensive Clinical Audits of Diagnostic Radiology Practices: A Tool for Quality Improvement. Quality Assurance Audit for Diagnostic Radiology Improvement and Learning (QUAADRIL)

    International Nuclear Information System (INIS)

    Interest in quality assurance processes and quality improvement in diagnostic radiology is being driven by a number of factors. These include the high cost and complexity of radiological equipment, acknowledgement of the possibility of increasing doses to patients, and the importance of radiological diagnosis to patient management within the health care environment. To acknowledge these interests, clinical audits have been introduced and, in Europe, mandated under a European Directive (Council Directive 97/47/EURATOM). Comprehensive clinical audits focus on clinical management and infrastructure, patient related and technical procedures, and education and research. This publication includes a structured set of standards appropriate for diagnostic radiology, an audit guide to their clinical review, and data collection sheets for the rapid production of reports in audit situations. It will be a useful guide for diagnostic radiology facilities wishing to improve their service to patients through timely diagnosis with minimal radiation dose.

  2. Regulatory good practices relating to inspection and enforcement. A compilation of the 1989/90 Peer Group discussion considerations as they relate to operational plants. Working material

    International Nuclear Information System (INIS)

    In 1974 the IAEA established a special Nuclear Safety Standards (NUSS) programme under which 5 Codes and 55 Safety Guides have been produced in the areas of Governmental Organization, Siting, Design, Operation and Quality Assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in a complex manner which ensured the best possible international consensus. This broad consensus is one of the reasons for a relatively general wording of the main principles and is sometimes a cause of problems in their application to the detailed design of nuclear power plants. The requirements, particularly those of the Codes, often need interpretation when applied to specific cases. In many areas national regulations and technical standards are available, but often even these do not answer all questions and only the practice used in applying certain rules fully reflects the outcome of the detailed consideration given to solving individual cases. In order to present further information on the application and interpretation in the NUSS Codes and Safety Guides, the preparation of a series of Safety Practice publications has been initiated. It is hoped that many Member States will be able to benefit from the experience presented in these documents. It is hoped that this publication will be useful for regulators and will also provide information for operating organizations. The document is a compilation of the reports of all of the 1989/90 Peer Group discussions held to consider regulatory inspection and enforcement of good practices. Therefore names of participated countries or the situation of regulatory practices reflect those at time when discussions took place. It identifies those common regulatory features which require continuous reinforcement and the examples of good regulatory practices which were recommended by the senior regulators attending the Peer Group

    May-Grünwald-Giemsa (MGG) stain is a Romanowsky-type, polychromatic stain as those of Giemsa, Leishman and Wright. Apart being the reference method of haematology, it has become a routine stain of diagnostic cytopathology for the study of air-dried preparations (lymph node imprints, centrifuged body fluids and fine needle aspirations). In the context of their actions of promoting the principles of quality assurance in cytopathology, the French Association for Quality Assurance in Anatomic and Cytologic Pathology (AFAQAP) and the French Society of Clinical Cytology (SFCC) conducted a proficiency test on MGG stain in 2013. Results from the test, together with the review of literature data allow pre-analytical and analytical steps of MGG stain to be updated. Recommendations include rapid air-drying of cell preparations/imprints, fixation using either methanol or May-Grünwald alone for 3-10minutes, two-step staining: 50% May-Grünwald in buffer pH 6.8 v/v for 3-5minutes, followed by 10% buffered Giemsa solution for 10-30minutes, and running water for 1-3minutes. Quality evaluation must be performed on red blood cells (RBCs) and leukocytes, not on tumour cells. Under correct pH conditions, RBCs must appear pink-orange (acidophilic) or buff-coloured, neither green nor blue. Leukocyte cytoplasm must be almost transparent, with clearly delineated granules. However, staining may vary somewhat and testing is recommended for automated methods (slide stainers) which remain the standard for reproducibility. Though MGG stain remains the reference stain, Diff-Quik(®) stain can be used for the rapid evaluation of cell samples. PMID:26188673

  7. Revitalizing quality assurance

    International Nuclear Information System (INIS)

    The image of someone inspecting or auditing often comes to mind when people hear the term quality assurance. Although partially correct, this image is not the complete picture. The person doing the inspecting or auditing is probably part of a traditional quality assurance organization, but that organization is only one aspect of a properly conceived and effectively implemented quality assurance system whose goal is improved facility safety and reliability. This paper introduces the underlying philosophies and basic concepts of the International Atomic Energy Agency's new quality assurance initiative that began in 1991 as part of a broad Agency-wide program to enhance nuclear safety. The first product of that initiative was publication in 1996 of a new Quality Assurance Code 50-C/SG-Q and fourteen related Safety Guides. This new suite of documents provide the technical and philosophical foundation upon which Member States can base their quality assurance programs. (author)

    1996-01-01

    This paper summarizes the method of the Computer Sciences Corporation Flight Dynamics Operation (FDO) quality assurance approach to support the National Aeronautics and Space Administration Goddard Space Flight Center Flight Dynamics Support Branch. Historically, a strong need has existed for developing systematic quality assurance using methods that account for the unique nature and environment of satellite Flight Dynamics mission support. Over the past few years FDO has developed and implemented proactive quality assurance processes applied to each of the six phases of the Flight Dynamics mission support life cycle: systems and operations concept, system requirements and specifications, software development support, operations planing and training, launch support, and on-orbit mission operations. Rather than performing quality assurance as a final step after work is completed, quality assurance has been built in as work progresses in the form of process assurance. Process assurance activities occur throughout the Flight Dynamics mission support life cycle. The FDO Product Assurance Office developed process checklists for prephase process reviews, mission team orientations, in-progress reviews, and end-of-phase audits. This paper will outline the evolving history of FDO quality assurance approaches, discuss the tailoring of Computer Science Corporations's process assurance cycle procedures, describe some of the quality assurance approaches that have been or are being developed, and present some of the successful results.

    Objectives The PROximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial has recently demonstrated that surgery is non-superior to non-operative treatment in the management of displaced proximal humeral fractures. The objective of this study was to assess current surgical practice in the context of the PROFHER trial in terms of patient demographics, injury characteristics and the nature of the surgical treatment. Methods A total of ten consecutive patients undergoing surgery for the treatment of a proximal humeral fracture from each of 11 United Kingdom hospitals were retrospectively identified over a 15 month period between January 2014 and March 2015. Data gathered for the 110 patients included patient demographics, injury characteristics, mode of surgical fixation, the grade of operating surgeon and the cost of the surgical implants. Results A majority of the patients were female (66%, 73 of 110). The mean patient age was 62 years (range 18 to 89). A majority of patients met the inclusion criteria for the PROFHER trial (75%, 83 of 110). Plate fixation was the most common mode of surgery (68%, 75 patients), followed by intramedullary fixation (12%, 13 patients), reverse shoulder arthroplasty (10%, 11 patients) and hemiarthroplasty (7%, eight patients). The consultant was either the primary operating surgeon or supervising the operating surgeon in a large majority of cases (91%, 100 patients). Implant costs for plate fixation were significantly less than both hemiarthroplasty (p managed non-operatively. Cite this article: Mr B. J. F. Dean.

    2001-01-01

    A method of analysis and quality-assurance practices were developed for the determination of four mosquito insecticides (malathion, metho-prene, phenothrin, and resmethrin) and one synergist (piperonyl butoxide) in water. The analytical method uses liquid-liquid extraction (LLE) and gas chromatography/mass spectrometry (GC/MS). Good precision and accuracy were demonstrated in reagent water, urban surface water, and ground water. The mean accuracies as percentages of the true compound concentrations from water samples spiked at 10 and 50 nanograms per liter ranged from 68 to 171 percent, with standard deviations in concentrations of 27 nanograms per liter or less. The method detection limit for all compounds was 5.9 nanograms per liter or less for 247-milliliter samples. This method is valuable for acquiring information about the fate and transport of these mosquito insecticides and one synergist in water.

    Full Text Available Abstract Background Across the developing world health care services are most often delivered in the private sector and social franchising has emerged, over the past decade, as an increasingly popular method of private sector health care delivery. Social franchising aims to strengthen business practices through economies of scale: branding clinics and purchasing drugs in bulk at wholesale prices. While quality is one of the established goals of social franchising, there is no published documentation of how quality levels might be set in the context of franchised private providers, nor what quality assurance measures can or should exist within social franchises. The aim of this study was to better understand the quality assurance systems currently utilized in social franchises, and to determine if there are shared standards for practice or quality outcomes that exist across programs. Methods The study included three data sources and levels of investigation: 1 Self-reported program data; 2 Scoping telephone interviews; and 3 In-depth field interviews and clinic visits. Results Social Franchises conceive of quality assurance not as an independent activity, but rather as a goal that is incorporated into all areas of franchise operations, including recruitment, training, monitoring of provider performance, monitoring of client experience and the provision of feedback. Conclusions These findings are the first evidence to support the 2002 conceptual model of social franchising which proposed that the assurance of quality was one of the three core goals of all social franchises. However, while quality is important to franchise programs, quality assurance systems overall are not reflective of the evidence to-date on quality measurement or quality improvement best practices. Future research in this area is needed to better understand the details of quality assurance systems as applied in social franchise programs, the process by which quality assurance

  2. Safe operation of critical assemblies and research reactors. Code of practice and Technical appendix. 1971 ed

    International Nuclear Information System (INIS)

    This book is in two parts. The first is a Code of Practice for the Safe Operation of Critical Assemblies and Research Reactors, prepared as a result of a meeting of experts which took place in Vienna on 20-24 May 1968. The Code has been prepared by the International Atomic Energy Agency in co-operation with the World Health Organization, and its publication is sponsored by both organizations. In addition, the Code was approved by the Board of Governors of the International Atomic Energy Agency on 16 December 1968 as part of the Agency's safety standards, which are applied to operations undertaken by Member States with the assistance of the Agency. The Board, in approving the publication of the present book, also recommended Member States to take the Code into account in the formulation of national regulations and recommendations. The second part of the book is a Technical Appendix to give information and illustrative samples that would be helpful in implementing the Code of Practice. This second part, although published under the same cover, is not part of the Code. An extensive Bibliography, amplifying the Technical Appendix, is included at the end.

  3. Practical applications of age-dependent reliability models and analysis of operational data

    International Nuclear Information System (INIS)

    The purpose of the workshop was to present the experience of practical application of time-dependent reliability models. The program of the workshop comprises the following sessions: -) aging management and aging PSA (Probabilistic Safety Assessment), -) modeling, -) operation experience, and -) accelerating aging tests. In order to introduce time aging effect of particular component to the PSA model, it has been proposed to use the constant unavailability values on the short period of time (one year for example) calculated on the basis of age-dependent reliability models. As for modeling, it appears that the problem of too detailed statistical models for application is the lack of data for required parameters. As for operating experience, several methods of operating experience analysis have been presented (algorithms for reliability data elaboration and statistical identification of aging trend). As for accelerated aging tests, it is demonstrated that a combination of operating experience analysis with the results of accelerated aging tests of naturally aged equipment could provide a good basis for continuous operation of instrumentation and control systems

  5. Safe operation of research reactors and critical assemblies. Code of practice and annexes. 1984 ed

    International Nuclear Information System (INIS)

    The safe operation of research reactors and critical assemblies (hereafter termed 'reactors') requires proper design, construction, management and supervision. This Code of Practice deals mainly with management and supervision. The provisions of the Code apply to the whole life of the reactor, including modification, updating and upgrading. The Code may be subject to revision in the light of experience and the state of technology. The Code is aimed at defining minimum requirements for the safe operation of reactors. Emphasis is placed on which safety requirements should be met rather than on specifying how these requirements may be met. The Code also provides guidance and information to persons and authorities responsible for the operation of reactors. The Code recommends that documents dealing with the operation of reactors and including safety analyses be prepared and submitted for review and approval to a regulatory body. Operation would be authorized on the understanding that it would comply with limits and conditions designed to ensure safety. The Code covers a wide range of reactor types, which gives rise to a variety of safety issues. Safety issues applicable to specific reactor types only (e.g. fast reactors) are not necessarily covered in this Code. Some of the recommendations in the Code are not directly applicable to critical assemblies. A recommendation may therefore be interpreted according to the type of reactor concerned. In such cases the words 'adequate' and 'appropriate' are used to mean 'adequate' or 'appropriate' for the type of reactor under consideration.

    This article proposes that problems of information security are mainly caused by the ineffective integration of people, operation, and technology, and not merely by the poor use of technology. Based on the information lifecycle, a model of the information security assurance lifecycle is presented. The crucial parts of the model are further discussed, with the information risk value and protect level, and the solution in each step of the lifecycle is presented with an ensured information risk level, in term of the integration of people, operation, and technology.

  7. Information technology and innovative drainage management practices for selenium load reduction from irrigated agriculture to provide stakeholder assurances and meet contaminant mass loading policy objectives

    Energy Technology Data Exchange (ETDEWEB)

    2009-10-15

    Many perceive the implementation of environmental regulatory policy, especially concerning non-point source pollution from irrigated agriculture, as being less efficient in the United States than in many other countries. This is partly a result of the stakeholder involvement process but is also a reflection of the inability to make effective use of Environmental Decision Support Systems (EDSS) to facilitate technical information exchange with stakeholders and to provide a forum for innovative ideas for controlling non-point source pollutant loading. This paper describes one of the success stories where a standardized Environmental Protection Agency (EPA) methodology was modified to better suit regulation of a trace element in agricultural subsurface drainage and information technology was developed to help guide stakeholders, provide assurances to the public and encourage innovation while improving compliance with State water quality objectives. The geographic focus of the paper is the western San Joaquin Valley where, in 1985, evapoconcentration of selenium in agricultural subsurface drainage water, diverted into large ponds within a federal wildlife refuge, caused teratogenecity in waterfowl embryos and in other sensitive wildlife species. The fallout from this environmental disaster was a concerted attempt by State and Federal water agencies to regulate non-point source loads of the trace element selenium. The complexity of selenium hydrogeochemistry, the difficulty and expense of selenium concentration monitoring and political discord between agricultural and environmental interests created challenges to the regulation process. Innovative policy and institutional constructs, supported by environmental monitoring and the web-based data management and dissemination systems, provided essential decision support, created opportunities for adaptive management and ultimately contributed to project success. The paper provides a retrospective on the contentious planning

    The project is titled 'Identification, Verification, and Compilation of Produced Water Management Practices for Conventional Oil and Gas Production Operations'. The Interstate Oil and Gas Compact Commission (IOGCC), headquartered in Oklahoma City, Oklahoma, is the principal investigator and the IOGCC has partnered with ALL Consulting, Inc., headquartered in Tulsa, Oklahoma, in this project. State agencies that also have partnered in the project are the Wyoming Oil and Gas Conservation Commission, the Montana Board of Oil and Gas Conservation, the Kansas Oil and Gas Conservation Division, the Oklahoma Oil and Gas Conservation Division and the Alaska Oil and Gas Conservation Commission. The objective is to characterize produced water quality and management practices for the handling, treating, and disposing of produced water from conventional oil and gas operations throughout the industry nationwide. Water produced from these operations varies greatly in quality and quantity and is often the single largest barrier to the economic viability of wells. The lack of data, coupled with renewed emphasis on domestic oil and gas development, has prompted many experts to speculate that the number of wells drilled over the next 20 years will approach 3 million, or near the number of current wells. This level of exploration and development undoubtedly will draw the attention of environmental communities, focusing their concerns on produced water management based on perceived potential impacts to fresh water resources. Therefore, it is imperative that produced water management practices be performed in a manner that best minimizes environmental impacts. This is being accomplished by compiling current best management practices for produced water from conventional oil and gas operations and to develop an analysis tool based on a geographic information system (GIS) to assist in the understanding of watershed-issued permits. That would allow management costs to be kept in

  10. Software Quality Assurance for Nuclear Safety Systems

    International Nuclear Information System (INIS)

    The US Department of Energy has undertaken an initiative to improve the quality of software used to design and operate their nuclear facilities across the United States. One aspect of this initiative is to revise or create new directives and guides associated with quality practices for the safety software in its nuclear facilities. Safety software includes the safety structures, systems, and components software and firmware, support software and design and analysis software used to ensure the safety of the facility. DOE nuclear facilities are unique when compared to commercial nuclear or other industrial activities in terms of the types and quantities of hazards that must be controlled to protect workers, public and the environment. Because of these differences, DOE must develop an approach to software quality assurance that ensures appropriate risk mitigation by developing a framework of requirements that accomplishes the following goals: (smbullet) Ensures the software processes developed to address nuclear safety in design, operation, construction and maintenance of its facilities are safe (smbullet) Considers the larger system that uses the software and its impacts (smbullet) Ensures that the software failures do not create unsafe conditions Software designers for nuclear systems and processes must reduce risks in software applications by incorporating processes that recognize, detect, and mitigate software failure in safety related systems. It must also ensure that fail safe modes and component testing are incorporated into software design. For nuclear facilities, the consideration of risk is not necessarily sufficient to ensure safety. Systematic evaluation, independent verification and system safety analysis must be considered for software design, implementation, and operation. The software industry primarily uses risk analysis to determine the appropriate level of rigor applied to software practices. This risk-based approach distinguishes safety

    Among the energy storage devices for applications in electric vehicles and stationary uses, lithium batteries typically deliver high performance. However, there is still a missing link between the engineering developments for large-scale batteries and the fundamental science of each battery component. Elucidating reaction mechanisms under practical operation is crucial for future battery technology. Here, we report an operando diffraction technique that uses high-intensity neutrons to detect reactions in non-equilibrium states driven by high-current operation in commercial 18650 cells. The experimental system comprising a time-of-flight diffractometer with automated Rietveld analysis was developed to collect and analyse diffraction data produced by sequential charge and discharge processes. Furthermore, observations under high current drain revealed inhomogeneous reactions, a structural relaxation after discharge, and a shift in the lithium concentration ranges with cycling in the electrode matrix. The technique provides valuable information required for the development of advanced batteries. PMID:27357605

  14. Best practices in the utilization and dissemination of operating experience at nuclear power plants

    International Nuclear Information System (INIS)

    IAEA Safety Standards Series No. SF-1 entitled Fundamental Safety Principles: Safety Fundamentals states the need for operating organizations to establish a programme for the collection and analysis of operating experience in nuclear power plants. Such a programme ensures that operating experience is analysed, events important to safety are reviewed in depth, lessons learned are disseminated to the staff of the organization and to relevant national and international organizations, operating experience is utilized and corrective actions are effectively implemented. This publication has been developed to provide advice and assistance to nuclear installations and related institutions, including contractors and support organizations, to strengthen and enhance their own feedback process through the implementation of best practices in the utilization and dissemination of operating experience and to assess their effectiveness. Dissemination and utilization of internal and external operating experience is essential in supporting a proactive safety management approach of preventing events from occurring. Few new events reveal a completely new cause or failure mechanism. Although not recognized prior to the event, most subsequent investigations identify internal or external industry operating experience that, if applied effectively, would have prevented the event. Therefore, the establishment of an effective utilization and dissemination process is very beneficial in raising awareness of the organization and individuals of available operating experience, and focussing effort in the implementation of the lessons learnt. This leads to improved safety and reliability. The present publication is the outcome of a coordinated effort involving the participation of experts of nuclear organizations in several Member States. It was written to complement the publication IAEA Services Series No. 10 entitled PROSPER Guidelines - Guidelines for Peer Review and for Plant Self-assessment of

  15. DOE financial assurance presentation

    International Nuclear Information System (INIS)

    The presentation topic is California's approach to license application review in meeting financial assurances for the proposed Ward Valley site. The purpose of the presentation is to provide information on specific financial assurance provisions contained in 10 CFR Part 61 and how California intends to satisfy those requirements. Also, as rate setter, California intends to demonstrate how it will assure allowable costs to the rate base though a financial prudency review. The key provisions of financial assurance are: 10 CFR Section 61.61 - This provision requires an applicant to demonstrate its ability to finance licensed activities; 10 CFR Section 61.62 - This provision requires an applicant to provide assurance that sufficient funds will be available for site closure and stabilization; and 10 CFR Section 61.63 - This provision requires an applicant to provide 'a copy of a binding arrangement, such as a lease, between the applicant and the disposal site owner, so that sufficient funds will be available to cover the costs of the institutional control period.' To assist California in its determination of financial assurance compliance to be demonstrated by the applicant for Part 61 requirements, is NUREG guidance document 1199 'Standard Format and Content of a License Application for a Low-Level Radioactive Waste (LLRW) Disposal Facility.' The detailed financial assurance provisions of NUREG 1199 are then embodied in NUREG 1200, 'Standard Review Plant for the Review of a License Application for a LLRW Disposal Facility.'

    This report describes and summarizes the results of a quality assurance (QA) study of the Gamma Knife, a nuclear medical device used for the gamma irradiation of intracranial lesions. Focus was on the physical aspects of QA and did not address issues that are essentially medical, such as patient selection or prescription of dose. A risk-based QA assessment approach was used. Sample programs for quality control and assurance are included. The use of the Gamma Knife was found to conform to existing standards and guidelines concerning radiation safety and quality control of external beam therapies (shielding, safety reviews, radiation surveys, interlock systems, exposure monitoring, good medical physics practices, etc.) and to be compliant with NRC teletherapy regulations. There are, however, current practices for the Gamma Knife not covered by existing, formalized regulations, standards, or guidelines. These practices have been adopted by Gamma Knife users and continue to be developed with further experience. Some of these have appeared in publications or presentations and are slowly finding their way into recommendations of professional organizations.

    Full Text Available Logging residues are often utilized as a Best Management Practice (BMP for stabilizing bare soil on forest harvesting operations. As utilization of woody biomass increases, concern has developed regarding availability of residues for implementing BMPs. The Virginia Department of Forestry (VDOF inspects all logging operations in Virginia and randomly selects a portion of harvests for more intensive audits. The VDOF BMP audit process intensively evaluates implementation of BMPs in seven categories (84 specific BMPs on 240 sites per year. This research analyzed three years of audit data (2010–2012 to quantify differences in BMP implementation between biomass and conventional harvesting operations. Among 720 audited tracts, 97 were biomass harvests, with 88 occurring in the Piedmont region. Only the streamside management zone (SMZ category had significant implementation percentage differences between biomass (83.1% and conventional harvests (91.4% (p = 0.0007 in the Piedmont. Specific areas where biomass harvesting operations had lower implementation were generally not related to a lack of residues available for implementing BMPs, but rather were from a lack of appropriate SMZs, overharvesting within SMZs, or inadequate construction of roads, skid trails, and stream crossings. Existing BMP recommendations already address these areas and better implementation would have negated these issues.

The latter modeling tool consists of a series of notational facilities, along with the proposed methodology for using these provided facilities. It is briefly used to exemplify two typical applications, which describe the structure and activities of an organization and those of a project. These descriptions have been designed according to the relevant ones of the standard military practice, aiming at noting the significance of the robust but overlooked military practice in civilian, commercial or governmental administrative applications.

  4. The application of optimization of protection to regulation and operational practice

    International Nuclear Information System (INIS)

    Optimization of protection and the problems of its practical application have been of concern for several years to the NEA Committee on Radiation Protection and Public Health. The present paper summarizes the principal conclusions of a meeting on this topic organized by the NEA in March 1988, with the participation of radiation protection, nuclear safety and radioactive waste management experts. From the results of the meeting it appears that there is now as increasingly solid background of knowledge and common understanding of the conceptual aspects of optimization of protection. However, its degree of implementation in the regulatory and operational practices is very uneven. The areas of plant design and operation appear the most promising in terms of examples of concrete application, whilst severe reservations exist in the nuclear safety community on the possibility of applying this approach to the prevention of nuclear accidents. There is also consensus on the fact that optimization of protection can only play a partial and minor role in decisions concerning the choice of radioactive waste disposal options

    The design and operation of a facility in which a magnetic resonance imaging (MRI) scanner is incorporated into a room used for surgical or endovascular cardiac interventions presents several challenges. MR safety must be maintained in the presence of a much wider variety of equipment than is found in a diagnostic unit, and of staff unfamiliar with the MRI environment, without compromising the safety and practicality of the interventional procedure. Both the MR-guided cardiac interventional unit at Kings College London and the intraoperative imaging suite at the National Hospital for Neurology and Neurosurgery are single-room interventional facilities incorporating 1.5 T cylindrical-bore MRI scanners. The two units employ similar strategies to maintain MR safety, both in original design and day-to-day operational workflows, and between them over a decade of incident-free practice has been accumulated. This article outlines these strategies, highlighting both similarities and differences between the units, as well as some lessons learned and resulting procedural changes made in both units since installation.

  6. Quality Assurance Analysis of a Large Multicenter Practice: Does Increased Complexity of Intensity-Modulated Radiotherapy Lead to Increased Error Frequency?

    International Nuclear Information System (INIS)

    Purpose: Error reduction is an important concern in clinical medicine. Intensity-modulated radiotherapy (IMRT) is an important advancement in radiation oncology that increases the complexity of treatment, potentially increasing the error risk. We studied the frequency and severity of errors in a large multicenter practice to ascertain the impact of quality improvement interventions over time, IMRT, and type of practice. Methods and Materials: We analyzed prospective data from three academic and 16 community practice sites with 24,775 courses of radiotherapy (9,210 IMRT courses and 15,565 non-IMRT) between January 2006 and December 2009. All IMRT treatment was performed using one centralized dose planning center for all sites. Results: We prospectively identified various errors or potential errors in 0.14 % vs. 0.40 % of the IMRT vs. non-IMRT courses (13/9,210 vs. 62/15,565, p = 0.0004) and excluding potential errors: 0.03 % for IMRT vs. 0.21% for non-IMRT. We developed the Clinical Radiotherapy Error Severity Scale (CRESS) to classify error severity from 1 to 10, with 1 to 3 for potential or completely correctable errors, 4 to 5 for dose variations 5%. Multivariate analyses of CRESS values, severity >4, and any error (including potential) correlated significantly reduced errors with IMRT (p = 0.0001–0.0024) but found no significant difference between the academic and community practice sites and no change in error frequency over time despite implementation of 39 system-wide policy changes by the centralized quality improvement committee. Conclusions: Despite the increase in complexity with IMRT compared with conventional radiotherapy, it can be delivered with reduced error frequency.

  7. Quality assurance during site construction. Pt. 1

    International Nuclear Information System (INIS)

    The first part of the lecture deals with the Quality Assurance system on the construction site in general. Basic site-related problems during contract implementation and the QA system requirements resulting from them are presented. The compilation of these requirements in a QA program and its inclusion in the site manual in written form are explained. Site organization, personnel qualification and procedures are referred to. Whereas the first part shows what is to be done, the second part shows how it can be put into practice on the site. All the essential points for the assurance of quality are addressed. They include, e.g., review of documents, incoming goods control, in-process surveillance, store controls, identification of components and systems, dealing with changes and deviations, documentation control and audits. By means of examples taken form practice the necessity of a well-functioning QA system, and the importance of quality-assuring measures on the site are pointed out. (orig.)

    2016-01-01

    European rabbits (Oryctolagus cuniculus) pose a major threat to agricultural production and conservation values in several countries. In New Zealand, population control via poisoning is a frontline method for limiting rabbit damage, with large areas commonly treated using the metabolic toxin sodium fluoroacetate (‘1080’) delivered in bait via aerial dispersal. However, this method is expensive and the high application rates of the active ingredient cause public antipathy towards it. To guide reductions in cost and toxin usage, we evaluated the economics and efficacy of rabbit control using an experimental approach of sowing 1080-bait in strips instead of the commonly-used broadcast sowing method (i.e. complete coverage). Over a 4-year period we studied aerial delivery of 0.02% 1080 on diced carrot bait over ~3500 ha of rabbit-prone land in the North and South islands. In each case, experimental sowing via strip patterns using 10–15 kg of bait per hectare was compared with the current best practice of aerial broadcast sowing at 30–35 kg/ha. Operational kill rates exceeded 87% in all but one case and averaged 93–94% across a total of 19 treatment replicates under comparable conditions; there was no statistical difference in overall efficacy observed between the two sowing methods. We project that strip-sowing could reduce by two thirds the amount of active 1080 applied per hectare in aerial control operations against rabbits, both reducing the non-target poisoning risk and promoting cost savings to farming operations. These results indicate that, similarly to the recently-highlighted benefits of adopting strip-sowing for poison control of introduced brushtail possums (Trichosurus vulpecula) in New Zealand, aerial strip-sowing of toxic bait could also be considered a best practice method for rabbit control in pest control policy.

  9. Assurance in corporate sustainability reporting in the United Kingdom: stakeholder and corporate perspectives

    OpenAIRE

    Pinilla-Urzola, Angela

    2011-01-01

    Sustainability assurance is developing rapidly in the United Kingdom, despite a negative stance from management. Previous studies have examined the practice as represented in statements from 2001 to 2004, companies’ reasons for commissioning assurance services, and the views of assurance providers on stakeholder-centred practice. Despite the importance of stakeholder participation within sustainability assurance exercises, far too little attention has been paid to stakeholders and their views...

  11. Best practices in identifying, reporting and screening operating experience at nuclear power plants

    International Nuclear Information System (INIS)

    IAEA Safety Standards Series No. SF-1 entitled Fundamental Safety Principles: Safety Fundamentals states the need for operating organizations to establish a programme for the collection and analysis of operating experience in nuclear power plants. Such a programme ensures that operating experience is analysed, events important to safety are reviewed in depth, lessons learned are disseminated to the staff of the organization and to relevant national and international organizations, and corrective actions are effectively implemented. This publication has been developed to provide advice and assistance to nuclear installations, and related institutions including contractors and support organizations to strengthen and enhance their own feedback process through the implementation of best practices in identifying, reporting and screening processes and to assess the effectiveness of the above areas. To support a proactive safety management approach the nuclear installations are enhancing the operating experience feedback (OEF) processes. For this purpose, the nuclear industry is striving to collect more information on occurrences that are useful to address the early signs of declining performance and improve operational safety performance. In this environment a strong reporting culture that motivates people to identify and report issues is an important attribute. As a consequence, the number and diversity of issues identified increases, and there is a need to set thresholds of screening for further treatment. Thus, the establishment of an effective identification, reporting and screening process is very beneficial to streamline the efforts, and ensure that major incidents and latent weaknesses are being addressed and that operating experience is treated according to its significance. This leads to improved safety and production. This publication was written to complement the publication IAEA Services Series No. 10 - PROSPER Guidelines - Guidelines for Peer Review and for

  13. Practical operation strategies for pumped hydroelectric energy storage (PHES) utilising electricity price arbitrage

    International Nuclear Information System (INIS)

    In this paper, three practical operation strategies (24Optimal, 24Prognostic, and 24Hsitrocial) are compared to the optimum profit feasible for a PHES facility with a 360 MW pump, 300 MW turbine, and a 2 GWh storage utilising price arbitrage on 13 electricity spot markets. The results indicate that almost all (∼97%) of the profits can be obtained by a PHES facility when it is optimised using the 24Optimal strategy developed, which optimises the energy storage based on the day-ahead electricity prices. However, to maximise profits with the 24Optimal strategy, the day-ahead electricity prices must be the actual prices which the PHES facility is charged or the PHES operator must have very accurate price predictions. Otherwise, the predicted profit could be significantly reduced and even become a loss. Finally, using the 24Optimal strategy, the PHES profit can surpass the annual investment repayments required. However, over the 5-year period investigated (2005-2009) the annual profit from the PHES facility varied by more than 50% on five out of six electricity markets considered. Considering the 40-year lifetime of PHES, even with low investment costs, a low interest rate, and a suitable electricity market, PHES is a risky investment without a more predictable profit. - Highlights: → Electricity generators typically operate on a market, including energy storage. → This paper assesses how energy storage can maximise its profits on a market. → Four operating strategies are assessed on 13 markets using a case study.→ One operating strategy achieves 97% of the profits feasible.→ However, the profit varies a lot depending on the market and capital costs.

  2. Repository construction management and quality assurance

    International Nuclear Information System (INIS)

    An emphasis on preventive rather than reactive management is key to an efficient construction management operation. Development of contingency plans to deal with unexpected adverse conditions, e.g., brine pockets during mining operations, are an integral part of the management program to ensure project safety, quality, cost, schedule and environmental objectives are met. A viable quality assurance program with active management support will optimize management effectiveness in reaching project goals. With adequate planning and perceptive application of the proper management controls, Quality Assurance becomes an essential ingredient for efficiently managing a job because it has been built into the management system rather than being an uninvolved peripheral entity. 6 references, 3 figures

  4. Monthly radiation protection training of workers: An evaluation of two years operational practice

    International Nuclear Information System (INIS)

    Radiation protection training and education is important in stimulating safety culture of occupationally exposed workers. Taking into account the mandatory requirements in relation to education and training a digital training tool was introduced for communication of personal dose results and regular information on radiation protection. This tool enables that personal dose reports are monthly sent to the individual mailbox of workers together with short comprehensive slideshows on radiation protection topics. After two years of operational practice a survey was organised to evaluate the training tool. The results show that the majority (92%) of the occupationally exposed workers are aware of the communication of personal dose results through e-mail. Furthermore, 81% of these workers are also aware of their monthly and cumulated dose level. The monthly information on radiation protection topics is however less consulted. Around 40% of the workers that noticed the link are indifferent to the monthly information. The interest in radiation protection issues increases however with the education level.

  7. Radiation protection optimization in the operation of German nuclear power plants. Principles and practical application

    International Nuclear Information System (INIS)

    Radiation exposure has to be reduced even below statutory limits to an extent that is reasonably attainable - a procedure which is international linguistic usage, is designated 'ALARA' (As Low As Reasonably Achievable). This principle has also become an established component of the safety culture in German nuclear power plants on the basis of statutory regulations and the regulations of the regulatory authority, as can be recognized from the excellent operating results for radiation exposure of personnel. The Working Panel 'Practical Radiation Protection' has therefore formulated a proposal for undertaking quantitative radiation protection optimization. This specifies generally valid criteria, which should support the relevant decisions on radiation protection in respect of the relativity of means and ends. (orig.)

    2016-02-01

    Full Text Available High concentrating photovoltaic (HCPV is a promising technique for the practical commercial utilization of solar energy. However, the performance of a HCPV system is significantly influenced by environmental parameters such as solar direct normal irradiance (DNI level and environmental temperature. This paper analyzes the performance of a 9 kWp grid-connected HCPV system in Kunming (Yunnan, China, during practical field operations over an entire year, and discusses how the environmental parameters influence the performance from both the energy conversion and power inversion perspective. Large variations in the performance of the HCPV system have been observed for different months, due to the respective changes in the environmental parameters. The DNI level has been found to be a dominant parameter that mainly determines the amount of energy production as well as the performance ratio of the HCPV system. The environmental temperature and wind velocity have less influence on the system performance ratio than expected. Based on the performance of the present HCPV system, a quantified correlation between the output power and the direct normal irradiance has been derived, which provides guidelines for both the cogent application and the modeling of HCPV techniques for grid-connected power generation.

    Energy Technology Data Exchange (ETDEWEB)

    1993-07-01

    The Safe Drinking Water Act established the Underground Injection Control (UIC) program to ensure that underground injection of wastes does not endanger an underground source of drinking water. Under UIC regulations, an injection well is a hole in the ground, deeper than it is wide, that receives wastes or other fluid substances. Types of injection wells range from deep cased wells to shallow sumps, drywells, and drainfields. The report describes the five classes of UIC wells and summarizes relevant regulations for each class of wells and for the UIC program. The main focus of the report is Class IV and V shallow injection wells. Class IV wells are prohibited and should be closed when they are identified. Class V wells are generally authorized by rule, but EPA or a delegated state may require a permit for a Class V well. This report provides recommendations on sound operating and closure practices for shallow injection wells. In addition the report contains copies of several relevant EPA documents that provide additional information on well operation and closure. Another appendix contains information on the UIC programs in 21 states in which there are DOE facilities discharging to injection wells. The appendix includes the name of the responsible regulatory agency and contact person, a summary of differences between the state`s regulations and Federal regulations, and any closure guidelines for Class IV and V wells.

    The generation of minimum operational, safety, performance, and interoperability requirements is an important aspect of safely integrating new NextGen components into the Communication Navigation Surveillance and Air Traffic Management (CNS/ATM) system. These requirements are used as part of the implementation and approval processes. In addition, they provide guidance to determine the levels of design assurance and performance that are needed for each element of the new NextGen procedures, including aircraft, operator, and Air Navigation and Service Provider. Using the enhanced Airborne Traffic Situational Awareness for InTrail Procedure (ATSA-ITP) as an example, this report describes some limitations of the current process used for generating safety requirements and levels of required design assurance. An alternative process is described, as well as the argument for why the alternative can generate more comprehensive requirements and greater safety assurance than the current approach.

  19. Next Generation CANDU Performance Assurance

    International Nuclear Information System (INIS)

    AECL is developing a next generation CANDU design to meet market requirements for low cost, reliable energy supplies. The primary product development objective is to achieve a capital cost substantially lower than the current nuclear plant costs, such that the next generation plant will be competitive with alternative options for large-scale base-load electricity supply. However, other customer requirements, including safety, low-operating costs and reliable performance, are being addressed as equally important design requirements. The main focus of this paper is to address the development directions that will provide performance assurance. The next generation CANDU is an evolutionary extension of the proven CANDU 6 design. There are eight CANDU 6 units in operation in four countries around the world and further three units are under construction. These units provide a sound basis for projecting highly reliable performance for the next generation CANDU. In addition, the next generation CANDU program includes development and qualification activities that will address the new features and design extensions in the advanced plant. To limit product development risk and to enhance performance assurance, the next generation CANDU design features and performance parameters have been carefully reviewed during the concept development phase and have been deliberately selected so as to be well founded on the existing CANDU knowledge base. Planned research and development activities are required only to provide confirmation of the projected performance within a modest extension of the established database. Necessary qualification tests will be carried out within the time frame of the development program, to establish a proven design prior to the start of a construction project. This development support work coupled with ongoing AECL programs to support and enhance the performance and reliability of the existing CANDU plants will provide sound assurance that the next generation

  2. The management role in quality assurance and utilization review

    International Nuclear Information System (INIS)

    This presentation covers a variety of concepts concerning quality assurance and utilization review as they relate to health care in general and, specifically, to radiology. Quality assurance has been a major part of health care for several years and has developed into the primary objective of the Joint Commission for the Accreditation of Hospitals. The historical perspective, an analysis of its changes, and how the process is currently used are presented. An opinion is then given on the future utility of quality assurance and how it may help or hinder health care. The topic of utilization review is also discussed, and an attempt is made to share the importance of the relationship between the review process and quality assurance. Finally, some practical suggestions are given on how quality assurance and utilization review can be used to identify existing or potential problems in radiology, how they can be monitored and corrected, and a practical system for follow-up

  3. Safety practices and standards, developments and incentives for international co-operation

    International Nuclear Information System (INIS)

    Some main points arising during the safety assessments carried out on a consultative basis by the CEC are explained. The authors stress the importance of studies of depressurization accidents and the appearance of probabilistic analysis methods in safety assessments. They indicate whether these safety evaluations, by the Commission's own experts as well as by external experts, bring up possible pragmatic approaches to improving the harmonization of the safety rules and practices at the European level. Some major safety concerns and activities systematically considered by the CEC are surveyed and how they relate to the initiatives in other international organizations and in industrially developed third countries. Emphasis is placed on the efforts towards a gradual harmonization of the many different techniques and standards applied on a world scale and within the European Community, in particular for reactors of the industrially developed type. Comparative information is provided on some national practices for technico-administrative authorization procedures (with examples) and on national work on the development of regulatory and voluntary standards. Of the technical issues that influence the health and safety aspects of nuclear power, the following are dealt with more specifically in the scope of a more harmonized approach: measures to prevent or mitigate accident conditions of internal or external origin; the application of the regulatory 'strictly radiological' and 'as low as reasonably achievable' population dose limits for normal effluent releases; and the validity of the permissible doses for occupational exposure. Finally, the various possibilities and limitations of probabilistic risk analysis methods in systems design, in regulatory requirements, in operational requirements, and in the definition of safety research programmes are discussed. Some implications of such methods, e.g. in the matter of equipment failure rate data collection, are examined

Amongst the technical issues which influence the health and safety aspects of nuclear fissions power, the following are dealt with here more specifically in the scope of a more harmonized approach: the means dedicated to the prevention and to the mitigation of accident conditions of internal or of external origin; the application of the regulatory ''strictly radiological'' and the ''as low as reasonably achievable'' population dose limits for normal effluents releases; the validity of the permissible doses for the professionally exposed; and the various possibilities and limitations of probabilistic risk analysis methods in systems design, in regulatory requirements, in operational requirements, in safety research programme definition are also discussed. Also some implications of such methods, e.g. in the matter

  5. International co-operation in radiation protection practices in the mining and milling of uranium

    International Nuclear Information System (INIS)

    Uranium mining industry has been associated with the history of excess lung cancer. Because of such epidemiological evidence, the subject of radiation protection in the nuclear mining industry has received increased attention in recent years both at national and international levels. The radiation hazards encountered in the uranium mining industry result primarily from the exposure to radon daughters. The exposure to external radiation in most mines is low; however, in the mining of high grade uranium ores external radiation exposure can be substantially higher. By adopting proper control measures, namely, regulatory control, appropriate safety standards, monitoring, engineering and other measures, medical surveillance, environmental protection and radioactive waste management, it is possible to minimize the health risk to a level deemed to be acceptable in the light of the benefit derived from the uranium mining industry. Recognizing the history of excess lung cancer among uranium miners and the nature of the associated radiation protection problems there have been considerable national and international efforts to develop safety standards, codes of practice and guides to improve the radiation protection practices for the protection of the workers and the general public. At the international level the role of the International Atomic Energy Agency (IAEA), the International Commission on Radiological Protection (ICRP), the International Labour Organisation (ILO), the World Health Organization (WHO), and the Organization for Economic Co-operation and Development/Nuclear Energy Agency (OECD/NEA) has been to develop and provide guidance for improved radiation protection in the uranium mining industry. In the paper the radiological problems in this industry, the types of control measures and the international efforts in harmonizing radiation protection measures are discussed. (author). 27 refs

    Objective: To setup a practical ultrasound quality assurance protocol in a large radiological center, results from transducer tests, phantom measurements and visual checks for physical faults were compared. Materials and methods: Altogether 151 transducers from 54 ultrasound scanners, from seven different manufacturers, were tested with a Sonora FirstCall aPerio{sup TM} system (Sonora Medical Systems, Inc., Longmont, CO, USA) to detect non-functional elements. Phantom measurements using a CIRS General Purpose Phantom Model 040 (CIRS Tissue Simulation and Phantom Technology, VA, USA) were available for 135 transducers. The transducers and scanners were also checked visually for physical faults. The percentages of defective findings in these tests were computed. Results: Defective results in the FirstCall tests were found in 17% of the 151 transducers, and in 16% of the 135 transducers. Defective image quality resulted with 15% of the transducers, and 25% of the transducers had a physical flaw. In 16% of the scanners, a physical fault elsewhere than in the transducer was found. Seven percent of the transducers had a concurrent defective result both in the FirstCall test and in the phantom measurements, 8% in the FirstCall test and in the visual check, 4% in the phantom measurements and in the visual check, and 2% in all three tests. Conclusion: The tested methods produced partly complementary results and seemed all to be necessary. Thus a quality assurance protocol is forced to be rather labored, and therefore the benefits and costs must be closely followed.

  18. Quality assurance of BNCT dosimetry

    International Nuclear Information System (INIS)

    The Phase I clinical trials for boron neutron capture therapy (BNCT) started in May 1999 in Otaniemi, Espoo. For BNCT no uniform international guidance for the quality assurance of dosimetry exists, so far. Because of the complex dose distribution with several different dose components, the international recommendations on conventional radiotherapy dosimetry are not applicable in every part. Therefore, special guidance specifically for BNCT is needed. To obtain such guidelines a European collaboration project has been defined. The aim of the project is a generally accepted Code of Practice for use by all European BNCT centres. This code will introduce the traceability of the dosimetric methods to the international measurement system. It will also ensure the comparability of the results in various BNCT beams and form the basis for the comparison of the treatment results with the conventional radiotherapy or other treatment modalities. The quality assurance of the dosimetry in BNCT in Finland covers each step of the BNCT treatment, which include dose planning imaging, dose planning, boron infusion, boron kinetics, patient positioning, monitoring of the treatment beam, characterising the radiation spectrum, calibration of the beam model and the dosimetric measurements both in patients (in viva measurements) and in various phantoms. The dose planning images are obtained using a MR scanner with MRI sensitive markers and the dose distribution is computed with a dose planning software BNCTRtpe. The program and the treatment beam (DORT) model used have been verified with measurements and validated with MCNP calculations in phantom. Dosimetric intercomparison has been done with the Brookhaven BNCT beam (BMRR). Before every patient irradiation the relationship between the beam monitor pulse rate and neutron fluence rate in the beam is checked by activation measurements. Kinetic models used to estimate the time-behavior of the blood boron concentration have been verified

  19. Quality assurance for SPECT systems

    International Nuclear Information System (INIS)

    Quality control is crucial to all aspects of nuclear medicine practice, including the measurement of radioactivity, the preparation of radiopharmaceuticals, the use of instrumentation to obtain images, computations to calculate functional parameters, and the interpretation of the results by the physician. It plays an integral part in fulfilling the regulatory requirement for establishing a comprehensive quality assurance programme as described in the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources. In 1984, the IAEA published IAEA-TECDOC-317, Quality Control of Nuclear Medicine Instruments, which addressed the quality control of radionuclide activity calibrators (also known as dose calibrators), gamma counters, and single and multiprobe counting systems, rectilinear scanners and scintillation cameras. An updated version of IAEA-TECDOC-317 was issued in 1991 as IAEA-TECDOC-602, and this included new chapters on scanner-computer systems and single photon emission computed tomography (SPECT) systems. The rapidly increasing use of SPECT systems during the 1990s prompted the need for a further update of these publications with special emphasis on SPECT systems, planar scintillation cameras, camera-computer systems and whole body scanning systems. Since rectilinear scanners have already been, or will soon be, phased out in Member States, the current publication excludes them completely. Quality assurance and quality control aspects of instrumentation for radioactivity measurements in nuclear medicine are addressed in Technical Reports Series No. 454, Quality Assurance for Radioactivity Measurement in Nuclear Medicine. The current publication is intended to be a resource for medical physicists, technologists and other healthcare professionals who are responsible for ensuring optimal performance of imaging instruments, particularly SPECT systems, in their respective institutions. It is intended for

    2008-01-01

    The present study aimed to identify firms supplying products to our university operating room (OR) that promote sustainable manufacturing methods. Results show that 72% of our suppliers, or 152 of 211 companies, do not promote sustainability practices in a salient manner. Multi-national firms document sustainability methods significantly more than U.S. divisions of multi-nationals or U.S. firms with chi-square = 157.93 (p sustainability promotion is an important marketing tool through which purchasers may begin the process of due diligence for product selection. Lack of sustainability information among suppliers in this study suggests that hospital procurement departments likely focus solely on issues like price or quality when making purchase decisions. These results also suggest an opportunity for healthcare administrators to evaluate more fully the products involved in the healthcare supply chain; the intrinsic, intangible value added to hospital products through sustainable manufacturing is consistent with responsible patient care and has the potential to create marketing and public relations value.

  1. Exploratory Shaft Facility quality assurance impact evaluation

    International Nuclear Information System (INIS)

    This report addresses the impact of the quality assurance practices used for the Exploratory Shaft Facility (ESF) design, and construction in licensing as part of the repository. Acceptance criteria used for evaluating the suitability of ESF QA practices are based on documents that had not been invoked for repository design or construction activities at the time of this evaluation. This report identifies the QA practices necessary for ESF design and construction licensability. A review and evaluation of QA practices for ESF design and construction resulted in the following conclusions. QA practices were found to be acceptable with a few exceptions. QA practices for construction activities were found to be insufficiently documented in implementing procedures to allow a full and effective evaluation for licensing purposes. Recommendations are provided for mitigating impacts to ensure compatibility of the QA practices with those considered necessary for repository licensing. 8 refs., 3 tabs

    1997-12-31

    This thesis investigates the relationship between operations and design and the design process, taking as case studies the two new platforms of Phillips Petroleum Company Norway on Ekofisk II, the Ekofisk 2/4 X drilling and wellhead platform and the Ekofisk 2/4 J processing and transportation platform. The emphasis has been on how to take into account operational experience in design. The two research questions are: (1) Are operations and design two communities-of-practice based on different kinds of knowledge?, and (2) What are the conditions for bridging knowledge in operations and design? From the theory reviewed and the field data presented the study concludes that physical closeness and integration of operations and design personnel, experience from the other community-of-practice, and mutual sympathy, trust, and respect, are important factors in bridging knowledge of the operations and design communities-of-practice and creating innovative solutions in design which transcend the existing knowledge in operations and design. 66 refs., 28 figs., 8 tabs.

    Precipitation forecasts for the upcoming rainy seasons are one of the most important sources of information for an early warning of droughts and water scarcity in West Africa. The meteorological services in West Africa perform seasonal precipitation forecasts within the framework of PRESAO (the West African climate outlook forum) since the end of the 1990s. Various sources of information and statistical techniques are used by the individual services to provide a harmonized seasonal precipitation forecasts for decision makers in West Africa. In this study, we present a detailed overview of the operational practice in West Africa including a first statistical assessment of the performance of the precipitation forecasts for drought situations for the past 18 years (1998 to 2015). In addition, a long-term hindcasts (1982 to 2009) and a semi-operational experiment for the rainy season 2013 using statistical and/or dynamical downscaling are performed to refine the precipitation forecasts from the Climate Forecast System Version 2 (CFSv2), a global ensemble prediction system. This information is post-processed to provide user-oriented precipitation indices such as the onset of the rainy season for supporting water and land use management for rain-fed agriculture. The evaluation of the individual techniques is performed focusing on water-scarce regions of the Volta basin in Burkina Faso and Ghana. The forecasts of the individual techniques are compared to state-of-the-art global observed precipitation products and a novel precipitation database based on long-term daily rain-gage measurements provided by the national meteorological services. The statistical assessment of the PRESAO forecasts indicates skillful seasonal precipitation forecasts for many locations in the Volta basin, particularly for years with water deficits. The operational experiment for the rainy season 2013 illustrates the high potential of a physically-based downscaling for this region but still shows

    The successful transition of research to operations (R2O) and operations to research (O2R) requires, above all, interaction between the two communities. We explore the role that close interaction and ongoing communication played in the successful fielding of three separate developments: an observation platform, a numerical model, and a visualization and specification tool. Additionally, we will examine how these three pieces came together to revolutionize interplanetary coronal mass ejection (ICME) arrival forecasts. A discussion of the importance of education and training in ensuring a positive outcome from R2O activity follows. We describe efforts by the meteorological community to make research results more accessible to forecasters and the applicability of these efforts to the transfer of space-weather research.We end with a forecaster "wish list" for R2O transitions. Ongoing, two-way communication between the research and operations communities is the thread connecting it all.

  5. Quality Assurance: Strategic Choices for Higher Education in Turkey

    2011-01-01

    Full Text Available As the number of students and higher education institutions in the world increases and there is a growing difficulty in financing the higher education systems, decision-makers have begun to show more interest in quality assurance. As quality assurance is given special attention in European countries, developing countries such as Turkey are interested in importing quality assurance systems. It is not possible to set quality assurance without sensitivity toward quality and without having quality as a cultural practice. The most likely encountered quality assurance approach in the world is that the higher education institution itself is responsible for its quality. In addition, external quality assurance procedures used are based on (academic peer review rather than on bureaucratic evaluations. Moreover, there is a lively debate across the world regarding the bureaucratic regulations of the quality assurance agencies and institutions that restrict the autonomy of higher education institutions. Without taking into consideration of the existing centralized structure of the higher education system in Turkey, of meeting social demands for the higher education, and of current higher education enrollment rates, the possible establishment of a quality assurance mechanism that may have sanctions on universities in Turkey is a threat to already limited autonomy of universities and is having a risk of additional bureaucratic burden. By laying out the roles and responsibilities of Turkish Council of Higher Education, the government and universities, this article discusses policies that should be adopted regarding the quality assurance.

    2002-07-01

    Full Text Available Abstract Background Much communicable disease control research has had little impact on local control programme policy and practice for want of an operational component. The operational research model – the systematic search for knowledge on interventions, tools or strategies that enhance programme effectiveness – is gaining recognition as an appropriate method for addressing perplexing questions within public health programmes. Methods A series of operational research studies were conducted to refine malaria diagnosis in Mpumalanga Province, South Africa between 1995 and 1999. The grounded theory approach was used with groups of experienced Masters of Public Health students in South Africa and Australia to analyse a compilation of these studies for determining positive and negative attributes of operational research that affect its ability to influence communicable disease control policy and practice. Results The principal positive attributes of the operational research studies were high local relevance, greater ability to convince local decision-makers, relatively short lag-time before implementation of findings, and the cost-effective nature of this form of research. Potential negative features elicited included opportunities forfeited by using scarce resources to conduct research and the need to adequately train local health staff in research methodology to ensure valid results and accurate interpretation of findings. Conclusions Operational research effectively influenced disease control policy and practice in rural South Africa, by providing relevant answers to local questions and engaging policy-makers. This resulted in accelerated inclusion of appropriate measures into a local communicable disease control programme.

  11. Silica dust control in small-scale building/structure demolition operations using good work practice guidance

    International Nuclear Information System (INIS)

    Work practices can influence exposure, especially in small-scale operations conducted by mobile work crews. This study evaluated the use of information on good work practice in control guidance sheets adapted from UK Silica Essentials guidance sheets by trained workers and supervisors employed in small-scale concrete and masonry demolition operations. A one-page employee silica task-based control guidance sheet for each of four demolition tasks and multiple-page silica control guidance for supervisors were developed. Interactive, hands-on worker training on these task-based good work practice controls was developed. Training was presented to 26 participants from two demolition crews. Feedback on the training and task-based good work practice control guidance sheets was elicited. Observations of work practices were made before and after training. Participants indicated gains in knowledge and checklists were used to document skill attainment. The quality of the training and usefulness of the material/skills was rated high by trainees. Increased use of water to suppress dust and wet cleaning methods on the job were documented following the training. Additional follow-up after training is required to determine long-term impact on sustained changes in work practices, and to evaluate the need for refresher training.

  12. Quality assurance programme for screen film mammography

    International Nuclear Information System (INIS)

    The application of radiation in human health, for both the diagnosis and treatment of disease, is an important component of the work of the IAEA. In the area of diagnostic radiology, this work is focused on quality assurance methods to both the promotion of the effective use of radiation for diagnostic outcome, through achieving and maintaining appropriate image quality, and also on dose determination to allow the monitoring and reduction of dose to the patient. In response to heightened awareness of the importance of patient dose contributed by radiology procedures, the IAEA published Dosimetry in Diagnostic Radiology: An International Code of Practice (Technical Reports Series No. 457) in 2007, to form a basis for patient dose determination for the Member States. Further to this, it is recognized that for complex diagnostic procedures, such as mammography, a detailed guidance document is required to give the professionals in the clinical centre the knowledge necessary to assess the patient dose, as well as to ensure that the procedure gives the maximal patient benefit possible. It is well documented that without the implementation of a quality culture and a systematic quality assurance programme with appropriate education, the detection of breast cancer cannot be made at an early enough stage to allow effective curative treatment to be undertaken. Currently there are a number of established quality assurance protocols in mammography from national and regional institutions, however, many of these protocols are distinctive and so a harmonized approach is required. This will allow the Member States to facilitate quality assurance in mammography in a standardized way which will also facilitate the introduction of national quality assurance programmes that are needed to underpin effective population screening programmes for breast cancer. Development of a quality assurance document for screen film mammography was started in 2005 with the appointment of a drafting

    International Nuclear Information System (INIS)

    In the nuclear industry design specifications for certain quality characteristics require that the final product be inspected by a sampling plan which can demonstrate product conformance to stated assurance levels. The Specified Assurance Level (SAL) Sampling Procedure has been developed to permit the direct selection of attribute sampling plans which can meet commonly used assurance levels. The SAL procedure contains sampling plans which yield the minimum sample size at stated assurance levels. The SAL procedure also provides sampling plans with acceptance numbers ranging from 0 to 10, thus, making available to the user a wide choice of plans all designed to comply with a stated assurance level

    Soares, D P

    1985-03-01

    A process is described for quality assurance in pharmaceutical purchasing and inventory control. A quality assurance program should ensure that quality drugs are purchased at the lowest price, drug products are available when needed, the system is managed efficiently, internal controls are provided, drug products are stored under appropriate conditions, and laws, regulations, accreditation standards, and procedures are followed. To meet these objectives, product quality, vendor performance, the department's system of internal controls, purchasing data, and storage conditions should be monitored. A checklist for evaluating purchasing and inventory practices and a sample audit form listing quality assurance criteria, standards, procedures, and recommended actions are provided. A quality assurance program for pharmaceutical purchasing and inventory control should define institution-specific criteria and standards and use these standards for continual evaluation of all aspects of the purchasing and inventory control system. Documentation of quality assurance activities should be provided for use by the purchasing department, hospital administration, and regulatory bodies. PMID:3985026

  17. Quality assurance and radiofrequency heating

    International Nuclear Information System (INIS)

    One pf the potential problems and limitations of scanning at high field strength is the deposition or radiofrequency (RF) power into the body. This paper proposes an inexpensive means of assessing radiofrequency power deposition in a magnet. This is particularly important at 3T where sequences approach Food and Drug Administration approved RF limits. It will also be of interest to operators at 1.5 T as part of their ongoing quality assurance programs. At 3T, we found that the RF power deposited in the magnet was less than that read by the MR power monitor. All measurements were performed with a 2.51 perspex spherical phantom.

    International Nuclear Information System (INIS)

    Components, subsystems and systems will be subjected to inspection and test as necessary to ensure compliance to applicable specifications, Acceptance Test Procedures and/or customer requirements. Quality Assurance will inspect each component, subsystem and system for selected mechanical and electrical defects. In addition, Quality Assurance will either perform, or verify performance of, and analyze, or verify analysis of, all required field and laboratory tests. If hardware is modified, repaired or replaced after final testing, necessary re-inspection and retest must be performed. Insofar as possible the component, subsystem or system will be released as acceptable upon completion of these activities. When nonconformances are detected during the course of site surveillance activities, MDAC or Gilbert/Commonwealth will initiate a Nonconformance Record for review by MDAC Quality Assurance and Project Engineering personnel. These nonconformances will be identified and dispositioned per MDAC Standard Practices with the advice and concurrence of Gilbert/Commonwealth personnel, if deemed appropriate. MDAC Quality Assurance personnel will witness the pre-operational testing and review the test data

    Practice refers to a characteristic way professionals use common standards to customize solutions to a range of problems. Practice includes (a) standards for outcomes and processes that are shared with one's colleagues, (b) a rich repertoire of skills grounded in diagnostic acumen, (c) an ability to see the actual and the ideal and work back and forth between them, (d) functional artistry, and (e) learning by doing that transcends scientific rationality. Communities of practice, such as dental offices, are small groups that work together in interlocking roles to achieve these ends. PMID:19413050

  6. Thinking in three's: Changing surgical patient safety practices in the complex modern operating room

    2012-01-01

    The three surgical patient safety events,wrong site surgery,retained surgical items (RSI) and surgical fires are rare occurrences and thus their effects on the complex modern operating room (OR) are difficult to study.The likelihood of occurrence and the magnitude of risk for each of these surgical safety events are undefined.Many providers may never have a personal experience with one of these events and training and education on these topics are sparse.These circumstances lead to faulty thinking that a provider won't ever have an event or if one does occur the provider will intuitively know what to do.Surgeons are not preoccupied with failure and tend to usually consider good outcomes,which leads them to ignore or diminish the importance of implementing and following simple safety practices.These circumstances contribute to the persistent low level occurrence of these three events and to the difficulty in generating sufficient interest to resource solutions.Individual facilities rarely have the time or talent to understand these events and develop lasting solutions.More often than not,even the most well meaning internal review results in a new line to a policy and some rigorous enforcement mandate.This approach routinely fails and is another reason why these problems are so persistent.Vigilance actions alone have been unsuccessful so hospitals now have to take a systematic approach to implementing safer processes and providing the resources for surgeons and other stakeholders to optimize the OR environment.This article discusses standardized processes of care for mitigation of injury or outright prevention of wrong site surgery,RSI and surgical fires in an action-oriented framework illustrating the strategic elements important in each event and focusing on the responsibilities for each of the three major OR agents-anesthesiologists,surgeons and nurses.A Surgical Patient Safety Checklist is discussed that incorporates the necessary elements to bring these team

  7. International Best Practice Basis for Assessing Recovery Operations. Annex II of Technical Volume 5

    International Nuclear Information System (INIS)

    This volume seeks to identify lessons learned related to post-accident recovery that may further improve preparedness worldwide. This objective assessment of the recovery programme is made according to international best practice. In the practice and assessment of radiation and nuclear safety, international best practice is a process or technique that is likely to consistently produce superior results. An important principle is that a ‘best’ practice can evolve to become better as improvements are discovered and lessons are learned from past experience. The lessons to be learned from the recovery programme as it unfolds in Japan will feed back into improving international best practice in post-accident recovery worldwide. Best practice is used to maintain quality and is a component of quality management systems and standards, such as ISO 9000. It is generally regarded as being the most efficient and effective way to accomplish desired outcomes. The body of best practice is used as a benchmark and for self assessment

  8. Regulatory good practices relating to monitoring and assessment of ageing nuclear power plants. A compilation of the 1991/92 Peer Group discussion considerations as they relate to operational plants. Working material

    International Nuclear Information System (INIS)

    In 1974 the IAEA established a Nuclear Safety Standards (NUSS) programme within which 5 Codes and 55 Safety Guides have been produced in the areas of Governmental Organization, Siting, Design, Operation and Quality Assurance. The NUSS Codes and Guides are a collection of basic and derived requirements for the safety of nuclear power plants with thermal neutron reactors. They have been developed in such a manner as to ensure the broadest international consensus. This broad consensus is one of the reasons for the relatively general wording of the main principles and sometimes causes problems when these principles are applied in the design of nuclear power plants. The requirements, particularly those of the Codes, often need interpretation in specific cases. In many areas national regulations and technical standards are available, but often these leave some questions unanswered and their practical application on a case-by-case basis is necessary. To assist in the application and interpretation of the NUSS Safety Standards and Safety Guides, the preparation of a number of Safety Practices publications has been commenced. Ibis publication is intended to assist regulators and also operating organizations. It is a compilation of the reports of the 1991/92 Peer Group discussions which considered regulatory good practices relating to monitoring and assessment of the ageing of nuclear power plants. Therefore names of participated countries in this documents are those at time of 1991/92 Peer Group discussions. It identifies those common regulatory features which require continuous reinforcement and examples of good regulatory practices that were recommended by senior regulators in the Peer Group discussions. The purpose of this publication is to provide a compilation of the 1991/92 Peer Group discussions relating to operational plant. This document the covers practices in the 20 countries participating in this round of Peer Group discussions. The document is a synopsis of

  9. On the state of measures of quality assurance for X-ray therapy units in Switzerland

    International Nuclear Information System (INIS)

    In Switzerland 57 X-ray therapy units are in operation at present. According to the Swiss ordinance on radiation protection, a quality-assurance program must regularly be applied in to these units. However, as the Swiss X-ray ordinance gives explicit control parameters only for diagnostic units, the present article issues proposals for the realization of a quality-assurance program for the therapy units. In this regard, it is distinguished between checks performed by technical personnel of the X-ray manufacturers and checks performed by a medical physicist with corresponding qualification, or under his supervision. The so-called mentor project for the performance of annual constancy checks in institutes without medical physicists is also taken into account. These proposals should be helpful for the discussion and clarification of competencies, hence contributing to standardization of control practices in Switzerland. (orig.)

  12. Revision of Krsko NPP Quality Assurance Plan

    International Nuclear Information System (INIS)

    International standards from nuclear power plant operation area are being frequently upgraded and revised in accordance with the continuous improvement philosophy. This philosophy applies also to the area of Quality Assurance, which has also undergone significant improvement since the early 1950s. Besides just nuclear industry, there are also other international quality standards that are being continuously developed and revised, bringing needs for upgrades also in the nuclear application. Since the beginning of Krsko NPP construction, the overall Quality Assurance program and its applicable procedures were in place to assure that all planned and systematic actions necessary to provide adequate confidence that an item or service will satisfy given requirements to quality, are in place. The overall requirements for quality as one of the major objectives for Krsko NPP operation are also set forth in the Updated Safety Analyses Report, the document that serves as a base for operating license. During more than 30 years of Krsko NPP operation, the quality requirements and related documents were revised and upgraded in several attempts. The latest revision 6 of QD-1, Quality Assurance Plan was issued during the year 2011. The bases for the revision were: Changes of the Slovenian regulatory requirements (ZVISJV, JV5, JV9?), Changes of Krsko NPP licensing documents (USAR section 13?), SNSA inspection requirements, Changes of international standards (IAEA, ISO?), Conclusions of first PSR, Implementation of ISO standards in Krsko NPP (ISO14001, ISO17025), Changes of plant procedures, etc. One of the most obvious changes was the enlargement of the QA Plan scope to cover interdisciplinary areas defined in the plant management program MD-1, such as Safety culture, Self-assessment, Human performance, Industrial Safety etc. The attachment of the QA Plan defining relationships between certain standards was also updated to provide matrix for better correlation of requirements of

  20. Quality assurance in diagnostic radiology in Hungary - first experiences in acceptance testing

    International Nuclear Information System (INIS)

    It is a general experience that optimum imaging with minimum patient doses, moreover, the safe operation and long life of X-ray equipment can be assured by regular measurement of technical parameters and checking of their constancy (routine performance testing) only. These tests are generally known as quality control, while together with the so-called corrective actions and its management it is called (physical-technical) quality assurance (QA). In the European Union, Directive 97/43/EURATOM about radiation protection of patients requires - among others - the good practice of (physical-technical) quality assurance. In Hungary, Decree No. 31/2001. (X.3.) of the Minister of Health harmonizes all of its requirements. Acceptance testing of new diagnostic X-ray equipment is assigned to NPHC-NRIRR. QA has been a daily practice in radiation therapy and nuclear medicine for a long time. A National Patient Dose Assessment Programme has also successfully run since 1989. We had, however, only few preliminaries in QA in diagnostic radiology in the second half of the eighties. Nowadays there are running QA programmes in some hospitals and mammography centres. he testing activity of our institute is independent from manufacturers, it is run within the frame of an accredited testing laboratory, using calibrated measuring instruments and based on valid international standards. So the started way of implementing QA in diagnostic radiology needs a lot of further efforts, adapting experiences of other countries, and also some financial help to reach an acceptable level in the EU.

  2. Quality Assurance of Ultrasonic Diagnosis in Breast

    International Nuclear Information System (INIS)

    Sonography is a subjective diagnostic method which is highly dependent on the experience of the operator and the equipment quality which requires real-time adjustments. Breast screening examination currently consists of clinical examination and mammography. Breast sonography, either supplementary to mammography or independently, is indicated for the dense breast, especially in younger women. Breast sonography is especially applicable for Korean women because of the denser breast parenchyma and the approximately 10-year younger incidence rate of breast cancer of Korean women compared to western women. To avoid unnecessary breast biopsy because of the high rate of false positive lesions in breast parenchyma, which is different from other body organs such as the liver or the kidney, a quality assurance program for breast sonography is essential. The quality assurance of breast ultrasound involves quality assurance of the equipment, imaging display and acquisition of clinical images, personnel qualifications and other aspects such as unification of lexicon, guideline of diagnostic examination and reporting system; US BI-RAD reporting system, assessment items and organization, education program, medical audit, certification issues, and medicolegal issues. A breast sonographic quality assurance system should be established before a scheme to initiate governmental medical insurance for breast sonography

    The quality assurance of treatment measures is legally required but as yet not generally established in practice. For interventional radiology, the introduction of quality assurance for PTA of arteries of the lower limbs is planned for January 1999. It is reasonable to subject at least the most important and/or most frequently performed interventions to quality management. In the present article, the term quality in the management of diseases is defined and the system of total quality management discussed at the levels structure, process, and results. For its application, parameters of quality measurement in the form of standards, criteria, and characteristic values are necessary and must be laid down by a team of experts on the basis of subjective experience and/or results in the literature. Practical quality assurance takes place not only within a clinic but also externally by comparison with other centers. Data collection and evaluation requires high-performance software that will be continuously improved, expanded, and adapted to current needs during regular meetings between the various users.

  13. Best Practices in the Management of an Operating Experience Programme at Nuclear Power Plants

    International Nuclear Information System (INIS)

    The IAEA Fundamental Safety Principles (IAEA Safety Standards Series No. SF-1) state the need for operating organizations to establish a programme for the feedback and analysis of operating experience in nuclear power plants. Such a programme ensures that operating experience is analysed, events important to safety are reviewed in depth, lessons learned are disseminated to the staff of the organization and to the relevant national and international organizations and corrective actions are effectively implemented. In IAEA Operational Safety Review Team (OSART) and Peer Review of the effectiveness of the Operational Safety Performance Experience Review (PROSPER) missions, weaknesses in the management of operating experience (OE) programmes have been identified as one of the root causes of the recurrence of events. This publication has been developed to provide advice and assistance to nuclear installation managers and related institutions, including contractors and support organizations, to strengthen and enhance the management of their OE processes. In this publication, a number of barriers to the successful management of an OE programme have been identified. Managers are encouraged to review and evaluate these barriers with a view to identifying and eliminating them within their own organizations

  16. Do radiation oncologists practice evidence based medicine? Results of a survey of management of the axilla in operable breast cancer

    International Nuclear Information System (INIS)

    In 2002 the Radiation Oncology Expert Advisory Group (ROEAG) of the National Breast Cancer Centre (NBCC) and RANZCR Faculty of Radiation Oncology, posted a questionnaire to practicing radiation oncologists in Australia and New Zealand seeking information on a variety of practical issues in the radiation oncology treatment of women with operable breast cancer. The questionnaire aimed to evaluate the influence of the guidelines and discussion papers published in a resource for radiation oncologists and registrars by the NBCC in the preceding three years. This paper reports on the responses to the questions relating to management of the axilla . A discussion paper containing guidelines on management of the axilla was published in 2001. 102 responses were received (41% response rate) with 93% acknowledging receipt of the paper on management of the axilla. 74% of respondents stated that this paper was important or very important to their practice. Four questions investigating when radiation oncologists would irradiate the entire axilla following an axillary dissection were asked. While 100% of respondents would irradiate the axilla if the surgeon reported unresectable disease in the axilla, 56% of respondents would irradiate the axilla if the pathologist describes extra nodal spread in the report on the operative specimen. The paper 'Management of the Axilla' clearly states that there is no level I or II evidence to support axillary irradiation in patients with' breast cancer based solely on reported extra nodal spread. Factors influencing radiation oncologist's clinical practice will be briefly discussed, as well as the implications for changing practice in response to new clinical trial evidence

  17. Future of Assurance: Ensuring that a System is Trustworthy

    Science.gov (United States)

    Sadeghi, Ahmad-Reza; Verbauwhede, Ingrid; Vishik, Claire

    Significant efforts are put in defining and implementing strong security measures for all components of the comput-ing environment. It is equally important to be able to evaluate the strength and robustness of these measures and establish trust among the components of the computing environment based on parameters and attributes of these elements and best practices associated with their production and deployment. Today the inventory of techniques used for security assurance and to establish trust -- audit, security-conscious development process, cryptographic components, external evaluation - is somewhat limited. These methods have their indisputable strengths and have contributed significantly to the advancement in the area of security assurance. However, shorter product and tech-nology development cycles and the sheer complexity of modern digital systems and processes have begun to decrease the efficiency of these techniques. Moreover, these approaches and technologies address only some aspects of security assurance and, for the most part, evaluate assurance in a general design rather than an instance of a product. Additionally, various components of the computing environment participating in the same processes enjoy different levels of security assurance, making it difficult to ensure adequate levels of protection end-to-end. Finally, most evaluation methodologies rely on the knowledge and skill of the evaluators, making reliable assessments of trustworthiness of a system even harder to achieve. The paper outlines some issues in security assurance that apply across the board, with the focus on the trustworthiness and authenticity of hardware components and evaluates current approaches to assurance.

  18. Solid waste management practices and review of recovery and recycling operations in Turkey

    International Nuclear Information System (INIS)

    This paper provides a general overview of solid waste data and management practices employed in Turkey during the last decade. Municipal solid waste statistics and management practices including waste recovery and recycling initiatives have been evaluated. Detailed data on solid waste management practices including collection, recovery and disposal, together with the results of cost analyses, have been presented. Based on these evaluations basic cost estimations on collection and sorting of recyclable solid waste in Turkey have been provided. The results indicate that the household solid waste generation in Turkey, per capita, is around 0.6 kg/year, whereas municipal solid waste generation is close to 1 kg/year. The major constituents of municipal solid waste are organic in nature and approximately 1/4 of municipal solid waste is recyclable. Separate collection programmes for recyclable household waste by more than 60 municipalities, continuing in excess of 3 years, demonstrate solid evidence for public acceptance and continuing support from the citizens. Opinion polls indicate that more than 80% of the population in the project regions is ready and willing to participate in separate collection programmes. The analysis of output data of the Material Recovery Facilities shows that, although paper, including cardboard, is the main constituent, the composition of recyclable waste varies strongly by the source or the type of collection point

    The objective of this study was to investigate calf management practices on beef cow-calf operations and determine associations with herd-level morbidity and mortality of pre-weaned calves. A 40-question survey about management practices, morbidity and mortality was administered to cow-calf producers by distributing paper surveys and by circulating an online link through various media. A total of 267 producers completed the survey. Data were analyzed with descriptive statistics and multivariable linear regression models. Average herd-level treatment risk for pre-weaning calf diarrhea (PCD) and bovine respiratory disease (BRD) were 4.9% and 3.0%, respectively. Average herd-level mortality within the first 24 h of life (stillbirth), from 1 to 7 days and 7 days to weaning were 2.3%, 1.1%, and 1.4%, respectively. Operations that never intervened at parturition had 4.7% higher PCD than those that occasionally did. On operations using small elastrator bands for castration, PCD was 1.9% higher than those using other methods. For every increase of 100 cows in herd size, BRD decreased by 1.1%. The association between BRD and PCD varied by when calving season began. Operations that used off-farm, frozen colostrum had a 1.1% increase in stillbirths. Operations that verified a calf had suckled had 0.7% lower mortality from 1 to 7 days of age. Those that intervened when colostrum was abnormal or that used small elastrator bands for castration had 1.9% and 1.4% higher mortality during the 1st week of life, respectively, compared with other operations. Mortality from 7 days to weaning was lower by 0.7% when calving season started in April compared with January or February and was higher by 1.0% for each additional week of calving season. Operations that intervened with colostrum consumption for assisted calvings had lower mortality from 7 days to weaning by 0.8% compared with those that did not. For every 1.0% increase in BRD, mortality from 7 days to weaning increased by 1

    The Lawrence Livermore National Laboratory has developed an extensive quality assurance program to provide high quality data and assessments in support of the Marshall Islands Dose Assessment and Radioecology Program. Our quality assurance objectives begin with the premise of providing integrated and cost-effective program support (to meet wide-ranging programmatic needs, scientific peer review, litigation defense, and build public confidence) and continue through from design and implementation of large-scale field programs, sampling and sample preparation, radiometric and chemical analyses, documentation of quality assurance/quality control practices, exposure assessments, and dose/risk assessments until publication. The basic structure of our radioassay quality assurance/quality control program can be divided into four essential elements; (1) sample and data integrity control; (2) instrument validation and calibration; (3) method performance testing, validation, development and documentation; and (4) periodic peer review and on-site assessments. While our quality assurance objectives are tailored towards a single research program and the evaluation of major exposure pathways/critical radionuclides pertinent to the Marshall Islands, we have attempted to develop quality assurance practices that are consistent with proposed criteria designed for laboratory accre

  5. Pre-operative irradiation with rectal carcinoma - clinical practices and results

    International Nuclear Information System (INIS)

    The goal of this work is to portray the effect of a high-dosed short-timed pre-irradiation on intra- and post-operative therapy of rectal carcinoma and the appearance of recidivistic tumors, respectively distant metastasis. This intermediate balance should help make the decision easier as to whether to continue to use this combined treatment form. The subjects consisted of 65 rectal carcinoma patients - pre-irradiated and operated - and 95 only operated patients. The irradiation was completed using a 8 MeV linear accelerator with ultra hard x-radiation. Dosing - (more than 80%) as short-timed irradiation with 16 Gy (4 x 4 Gy in 2 days) - 25 Gy (10 x 2,5 Gy in 12 days); average field size 150 mm x 150 mm. There were no significant differences with regard to intra- and post-operative complications, late complications or distant metastasis, but there was with tumor recidivision reduced with pre-irradiated. Regarding the survival rate, there was a slight tendency in favor of the pre-irradiated. (orig./MG)

  6. Measurement of Lubricating Condition between Swashplate and Shoe in Swashplate Compressors under Practical Operating Conditions

    Suzuki, Hisashi; Fukuta, Mitsuhiro; Yanagisawa, Tadashi

    In this paper, lubricating conditions between a swashplate and a shoe in a swashplate compressor for automotive air conditioners is investigated experimentally. The conditions are measured with an electric resistance method that utilizes the swash plate and the shoe as electrodes respectively. The instrumented compressor is connected to an experimental cycle with R134a and operated under various operating conditions of pressure and rotational speed. An improved measurement technique and applying a solid contact ratio to the measurement results permit to measure the lubricating condition at high rotational speed (more than 8000 rpm) and to predic an occurrence of scuffing between the swashplate and the shoe, and therefore enables a detailed study of lubricating characteristics. It is shown by the measurement that the voltage of the contact signal decreases, which means better lubricating condition, with the decrease of the compression pressure and with the increase of the rotational speed from 1000 rpm through 5000 rpm. The lubricating condition tends to worsen at more than 5000 rpm. Furthermore, it is confirmed that the lubricating condition under transient operation is worse obviously as compared with that under steady-state operation.

  7. Administrative practices to limit dose in environmental cleanup operations involving plutonium

    International Nuclear Information System (INIS)

    The Rocky Flats Plant is a U.S. Federal Government-owned contractor-operated facility utilizing plutonium, uranium, beryllium and other metals to fabricate nuclear components for the United States weapons programme. The plant is located 26km from Denver, Colorado. During the history of plant operations, various events occurred which allowed radioactivity to reach the environment. When these events occurred, plutonium operations in the United States were conducted under the guidance of ICRP 2 recommendations. Radioactivity concentrations measured in air, water, and soil, together with calculations of doses to workers and the population, were well within guide values. The advent of ALARA in 1973 (ICRP 22) and further development of dose limitation concepts (ICRP 26), necessitated reevaluation of contaminated areas to determine improvements that might be needed. Heightened public environmental interest and increased legal regulations emphasized the need to ensure that doses were limited to the lowest levels reasonably achievable. Documentation of past releases and a radiometric survey of the plant site identified areas where environmental cleanup could be beneficial. Cleanup priorities were established, and scope of work to be accomplished was defined for funding request. Stringent, but achievable, criteria were developed for environmental cleanup activities. Action limits far below existing legal limitations were defined based on background measurements and plant operating experience. Exposure and emission data were periodically reported. No measurable exposures resulted to workers involved in environmental cleanup efforts. Monitoring stations near cleanup areas show a decline in activity following cleanup efforts. (author)

    Fuel cell power plants (FCPPs) have been taken into a great deal of consideration in recent years. The continuing growth of the power demand together with environmental constraints is increasing interest to use FCPPs in power system. Since FCPPs are usually connected to distribution network, the effect of FCPPs on distribution network is more than other sections of power system. One of the most important issues in distribution networks is optimal operation management (OOM) which can be affected by FCPPs. This paper proposes a new approach for optimal operation management of distribution networks including FCCPs. In the article, we consider the total electrical energy losses, the total electrical energy cost and the total emission as the objective functions which should be minimized. Whereas the optimal operation in distribution networks has a nonlinear mixed integer optimization problem, the optimal solution could be obtained through an evolutionary method. We use a new evolutionary algorithm based on Fuzzy Adaptive Particle Swarm Optimization (FAPSO) to solve the optimal operation problem and compare this method with Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Differential Evolution (DE), Ant Colony Optimization (ACO) and Tabu Search (TS) over two distribution test feeders.

    Mellat Parast, Mahour

    The trend toward globalization has challenged management thinking, organizational practices, and the ways companies interact with their customers and suppliers as well as with other segments of society. One such practice, Total Quality Management (TQM), has emerged as a management paradigm for enhancing organizational performance and profitability, to the extent that it has been regarded as "the second industrial revolution" (Kanji, 1990). Despite extensive research in quality management, little empirical research has been done on this in an international context, especially in the Middle East. This study attempts to investigate: (1) the relationship among quality management constructs based on the Malcolm Baldrige National Quality Award; and (2) the effect of quality management practices on operational and business results in the petroleum industry. A validated and reliable survey instrument was used for the study to collect data from 31 project managers/consultants in the petroleum industry in Iran. The results of the correlation analysis show that top management support is the major driver of quality management, which significantly correlates with other quality management practices. It was also found that customer orientation is not significantly correlated with external quality results (profitability). A regression analysis indicated top management support, employee training, and employee involvement as the three statistically significant variables in explaining the variability in internal quality results. Furthermore, it was found that internal quality results was statistically significant in explaining the variability of external quality results.

    Partial nitrification techniques, such as the continuously aerated SHARON process, have been denoted for quite a while as very promising for improved sustainability of wastewater treatment. Combination of such a SHARON process with the Anammox process, where ammonium is oxidised with nitrite to nitrogen gas under anoxic conditions, leads to cost-efficient and sustainable nitrogen removal from concentrated streams. In this study practical experiences during start-up and operation of a lab-scale SHARON reactor are discussed. Special attention is given to the start-up in view of possible toxic effects of high ammonium and nitrite concentrations (up to 4000 mgN/l) on the nitrifier population and because the reactor was inoculated with sludge from a SBR reactor operated under completely different conditions. Because of these considerations, the reactor was first operated as a SBR to prevent biomass wash out and to allow the selection of a strong nitrifying population. A month after the inoculation the reactor was switched to normal chemostat operation. As a result the nitrite oxidisers were washed out and only the ammonium oxidisers persisted in the reactor. In this contribution also some practical considerations, such as mixing, evaporation and wall growth, concerning the operation of a continuously aerated SHARON reactor are discussed. These considerations are not trivial, since the reactor will be used for kinetic characterisation and modelling studies. Finally the performance of the SHARON reactor under different conditions is discussed in view of its coupling with an Anammox unit. Full nitrification was proven to be feasible for nitrogen loads up to 1.5 g/l d, indicating the possibility of the SHARON process to treat highly loaded nitrogen streams. PMID:15296140

  17. Improvements in the management of safety in research reactor operation through appropriate application of selected power reactor good practices

    International Nuclear Information System (INIS)

    Research reactor managers are increasingly implementing improvements in their management of safety through the application of good practices originally developed as power reactor programs. This paper considers ways to select practices to emulate, effectively incorporate them into a research reactor program and evaluate their contribution to safety. Relative to research reactors, power reactor programs look relatively homogeneous when considering source terms, stored energy, core power density, operating cycles, plant systems and staff sizes. They have potential hazard consequences that require effective safety management programs. Finally, power reactors generate a stream of revenue to fund these programs. The power reactor community has combined their resources with the homogeneity of their challenge to create impressive safety management tools, many of which can be effectively implemented in the research reactor community. However, not all programs can be effectively implemented in all research reactors. number of power reactor programs are analyzed in the paper with consideration of their effective implementation and potential contribution to research reactor.

    2016-07-01

    Within the framework of an internal armed conflict in Colombia, the use of antipersonnel mines by revolutionary armed forces represents a strategic factor for these groups. Antipersonnel mines are used by these revolutionary forces as a mean to hinder the advancement of the national armed forces in the recovery of territory and to protect tactical natural resources and illegal economies within a given area. These antipersonnel mines and improvised explosive devices (IEDs) are not of industrial manufacturing, and have a variety of activating mechanisms as well as non-metal materials which make them difficult for successful detection. The Colombian experience strongly represents the current need for advanced research and development of effective field operations within its affected territory. Current efforts are focused on a more operational demining perspective in coca cultivation sites in charge of mobile squadrons of eradication (EMCAR) from the National Police of Colombia working towards a future humanitarian demining upon an eventual peace process. The objectives of this review are not only to highlight already existing mine detection methods, but present a special emphasis on the role of mine detection canine teams in the context of this humanitarian issue in Colombia. This review seeks to bring together a description of chemical interactions of the environment with respect to landmine odor signatures, as well as mine detection dog operational perspectives for this specific detection task. The aim is to highlight that given the limited knowledge on the subject, there is a research gap that needs to be attended in order to efficiently establish optimal operating conditions for the reliable performance of mine detection dogs in Colombian demining field applications.

    The aim of this study was to evaluate the stress levels and stress coping strategies of nursing students in their first operating room experience. This descriptive study was done with 126 nursing students who were having an experience in an operating room for the first time. Data were collected by using Personal Information Form, Clinical Stress Questionnaire, and Styles of Coping Inventory. The nursing students mostly had low clinical stress levels (M = 27.56, SD = 10.76) and adopted a self-confident approach in coping with stress (M = 14.3, SD = 3.58). The nursing students generally employed a helpless/self-accusatory approach among passive patterns as their clinical stress levels increased, used a self-confident and optimistic approach among active patterns as their average age increased, and those who had never been to an operating room previously used a submissive approach among passive patterns. The results showed that low levels of stress caused the nursing students to use active patterns in coping with stress, whereas increasing levels of stress resulted in employing passive patterns in stress coping. The nursing students should be ensured to maintain low levels of stress and use active patterns in stress coping. PMID:25801218

  8. Categorisation of waste streams arising from the operation of a low active waste incinerator and justification of discharge practices

    International Nuclear Information System (INIS)

    Waste streams arising from the low active waste incinerator at Harwell are described, and the radiological impact of each exposure pathway discussed. The waste streams to be considered are: (i) discharge of scrubber liquors after effluent treatment to the river Thames; (ii) disposal of incinerator ash; and (iii) discharge of airborne gaseous effluents to the atmosphere. Doses to the collective population and critical groups as a result of the operation of the incinerator are assessed and an attempt made to justify the incineration practice by consideration of the radiological impact and monetary costs associated with alternative disposal methods.

  9. Quality assurance during site construction

    International Nuclear Information System (INIS)

    During the time of planing and construction of a nuclear power plant, the following proceeding is approved: - the deliverer of a nuclear power plant provides the reports fixing the quality assurance program, it means that he is responsible to write the safety analysis report, the specifications for the erection of the components, the working manuals and specifications for testing (eg nondestr. testing) - the manufacturing of components or systems will be controlled by an own independent quality assurance group, provided that this group was checked by the quality assurance group of the applicant - the TUeV with its independent assessors will fix the requirements relating to quality assurance in its assessment. On this basis the examination of the applicants specifications, working manuals, testing specifications will be done. The efficiency of quality assurance at the manufacturer and at the applicant will be checked by the TUeV specialists by considering specifications of modifications, repairs or tolerances. A mean point of the quality assurance in Germany is the dynamic adjustment, of an action on the latest state of engineering or science. If there exists a change of rules or guidelines, the quality assurance requirements have to be fit on this state in so far as it is feasible from the technical point of view. (orig./RW)

  10. Ballistic quality assurance

    International Nuclear Information System (INIS)

    This review describes the ballistic quality assurance for stereotactic intracranial irradiation treatments delivered with Gamma KnifeR either dedicated or adapted medical linear accelerators. Specific and periodic controls should be performed in order to check the mechanical stability for both irradiation and collimation systems. If this step remains under the responsibility of the medical physicist, it should be done in agreement with the manufacturer's technical support. At this time, there are no recent published guidelines. With technological developments, both frequency and accuracy should be assessed in each institution according to the treatment mode: single versus hypo-fractionated dose, circular collimator versus micro-multi-leaf collimators. In addition, 'end-to-end' techniques are mandatory to find the origin of potential discrepancies and to estimate the global ballistic accuracy of the delivered treatment. Indeed, they include frames, non-invasive immobilization devices, localizers, multimodal imaging for delineation and in-room positioning imaging systems. The final precision that could be reasonably achieved is more or less 1 mm. (authors)

    As control rooms are modernized with new digital systems at nuclear power plants, it is necessary to evaluate the operator performance using these systems as part of a verification and validation process. There are no standard, predefined metrics available for assessing what is satisfactory operator interaction with new systems, especially during the early design stages of a new system. This report identifies the process and metrics for evaluating human system interfaces as part of control room modernization. The report includes background information on design and evaluation, a thorough discussion of human performance measures, and a practical example of how the process and metrics have been used as part of a turbine control system upgrade during the formative stages of design. The process and metrics are geared toward generalizability to other applications and serve as a template for utilities undertaking their own control room modernization activities.

  12. Exclusion, exemption and clearance in the mining and minerals industry: Practical application to South African operations

    International Nuclear Information System (INIS)

    Although South Africa has no primary uranium mines, a major portion of its very large mining industry involves minerals with moderately elevated levels of naturally-occurring radionuclides, typical of elevated levels found in similar mineral deposits worldwide. Evidence both locally and internationally suggests that, where radioactive elements are not concentrated or extracted, such operations cannot normally give rise to undue radiological risks. The concept of exclusion should therefore play the major role in establishing which minerals-related operations should be subject to regulatory control, but exclusion criteria, which tend to be numerical rather than descriptive, vary widely between countries - in South Africa, very little is excluded and opportunities for granting exemptions are limited. The need for exemptions and clearance would be reduced if more extensive use of the exclusion concept were made, but it is nevertheless important to have better guidance on determining appropriate numerical exemption and clearance criteria - again, there are currently wide variations between countries, one example being the surface activity clearance levels for the reuse or recycling of uranium-contaminated items. Two examples, relating to gold mining tailings disposal and recycling of contaminated scrap steel respectively, are used to illustrate the difficulties that have arisen in South Africa on the clearance of low activity materials from the mining and minerals industry. Radon is identified as requiring separate consideration, and is the one area where more specific international guidance, based on action levels for intervention, is available. The action level for workplaces recommended by the IAEA would appear to represent a common basis for exclusion and exemption with respect to radon exposures from mining and minerals operations. For public exposures, the corresponding action level for homes, although not specifically intended for dealing with radon from nearby

    Functional Near Infrared Spectroscopy (fNIRS) is an emerging neuronal measurement technique with many advantages for application in operational and training contexts. Instrumentation and protocol improvements, however, are required to obtain useful signals and produce expeditiously self-applicable, comfortable and unobtrusive headgear. Approaches for improving the validity and reliability of fNIRS data for the purpose of sensing the mental state of commercial aircraft operators are identified, and an exemplary system design for attentional state monitoring is outlined. Intelligent flight decks of the future can be responsive to state changes to optimally support human performance. Thus, the identification of cognitive performance decrement, such as lapses in operator attention, may be used to predict and avoid error-prone states. We propose that attentional performance may be monitored with fNIRS through the quantification of hemodynamic activations in cortical regions which are part of functionally-connected attention and resting state networks. Activations in these regions have been shown to correlate with behavioral performance and task engagement. These regions lie beneath superficial tissue in head regions beyond the forehead. Headgear development is key to reliably and robustly accessing locations beyond the hair line to measure functionally-connected networks across the whole head. Human subject trials using both fNIRS and functional Magnetic Resonance Imaging (fMRI) will be used to test this system. Data processing employs Support Vector Machines for state classification based on the fNIRS signals. If accurate state classification is achieved based on sensed activation patterns, fNIRS will be shown to be useful for monitoring attentional performance.

  14. Code of practice for the design and safe operation of non-medical irradiation facilities (1988)

    International Nuclear Information System (INIS)

    This Code establishes requirements for the design and operation of irradiation facilities which use X-rays, electrons or gamma radiation for non-medical purposes such as the sterilisation of therapeutic goods. These requirements aim to ensure that exposure of workers and members of the public to ionizing and non-ionizing radiation as well as to noxious gases and radioactive contamination of the environment and facilities are controlled through the design of engineering safety features, approved administrative controls and appropriate radiation monitoring

    Characterizing the factors that affect reliability of a photovoltaic (PV) power plant is an important aspect of optimal asset management. This document describes the many factors that affect operation and maintenance (O&M) of a PV plant, identifies the data necessary to quantify those factors, and describes how data might be used by O&M service providers and others in the PV industry. This document lays out data needs from perspectives of reliability, availability, and key performance indicators and is intended to be a precursor for standardizing terminology and data reporting, which will improve data sharing, analysis, and ultimately PV plant performance.

    Despite significant advances in technology and intraoperative techniques over the last century, operations on the brain and spinal cord continue to carry a significant risk of serious morbidity or mortality. Potentially avoidable technical errors are well recognized as contributing to poor surgical outcome. Surgical education is undergoing overwhelming change, in part as a result of changes in the economic, political, social, cultural, and technological climates in which it operates. Shortened training, reductions in the working week, economic difficulties, and increasing emphasis on patient safety have required educators to radically rethink the way in which surgical education is delivered. This has resulted in the development of simulation technology, mental script-based rehearsal, and simulation-based deliberate practice. Although these tools and techniques are garnering increasing evidence for their efficacy, the evidence for their use in neurosurgery is somewhat more limited. Here, we review the theory behind these tools and techniques and their application to neurosurgery. We conclude that further research into the utility of these tools and techniques is essential for determining their widespread adoption. If they ultimately prove to be successful, they may have a central role in neurosurgical training in the 21st century, improving the acquisition of technical skills in a specialty in which a technical error can result in grave consequences.

    Space debris mitigation is one objective of the French Space Operations Act (FSOA), in line with Inter-Agency Space Debris Coordination Committee (IADC) recommendations, through the removal of non-operational objects from populated regions. At the end of their mission, space objects are to be placed on orbits that will minimize future hazards to space objects orbiting in the same region. The FSOA, which came into force in 2010, ensures that technical risks associated with space activities are properly mitigated. The Act confers CNES a central support role in providing technical expertise to government on regulations dealing with space operations. In order to address the compliance of disposal orbits with the law technical requirements, CNES draws up Good Practices as well as a dedicated tool, Semi-analytic Tool for End of Life Analysis (STELA). The verification of the criteria of the French Space Operations Act requires long term orbit propagation to evaluate the evolution of the orbital elements over long time scales (up to more than 100 years). The Good Practices define the minimum dynamical model required to compute the orbital evolution with sufficient accuracy, and detail key computation hypotheses such as drag and reflecting areas, drag coefficient, reflectivity coefficient, solar activity, atmospheric density model and so on. They also recommend a methodology adapted to each orbit type (LEO, GEO, GTO) to assess the criteria of the French Space Operations Act. The most recent works have concerned GTO, for which some couplings occur between dynamic perturbations. A small change in the initial conditions or in the estimation of the drag effect will significantly change the entrance conditions in resonance areas and thus the orbital evolution. To cope with this difficulty, a statistical method has been developed. This paper gives an overview of the Good Practices for orbit propagation in LEO, GEO and GTO as well as a brief description of the STELA tool. It

    Full Text Available The microkernel system (as opposite to monolithic systems has been developed for severalyears, with the hope that microkernels could solve the problems of other operating systems.However, the evolution of the microkernel systems did not go as many people expected. Becauseof faultinesses of the design in system structure, the performance of the first generation ofmicrokernel operating systems was disappointing. The overhead of the system was too high tobear for users. However, the second-generation microkernel system uses an improved designarchitecture that could substantially reduce the overhead in previous microkernel systems.This project evaluates the system performance of the MINIX3.1.2a and compares the results withthe performance of Linux by using Unixbench system evaluating tool. By this way, it could testifywhether the microkernel systems could be more flexible, portable and secure than monolithicoperating systems. Unixbench could give sufficient statistics on different capacities of MINIX3 andLinux, such as system call overhead, pipe throughput, arithmetic test and so on. The resultillustrates MINIX3 has better performance on Shell Scripts running and Arithmetic test and Linuxhas better performance on other aspects such as system call overhead, process creation and soon. Furthermore, we provide a more detailed analyse on the microkernel Minix 3 system andpropose a method that could improve the performance of the MINIX3 system.

    Full Text Available Introduction: Physicians dedicate substantial time to documentation. Scribes are sometimes used to improve efficiency by performing documentation tasks, although their impacts have not been prospectively evaluated. Our objective was to assess a scribe program’s impact on emergency department (ED throughput, physician time utilization, and job satisfaction in a large academic emergency medicine practice. Methods: We evaluated the intervention using pre- and post-intervention surveys and administrative data. All site physicians were included. Pre- and post-intervention data were collected in fourmonth periods one year apart. Primary outcomes included changes in monthly average ED length of stay (LOS, provider-specific average relative value units (RVUs per hour (raw and normalized to volume, self-reported estimates of time spent teaching, self-reported estimates of time spent documenting, and job satisfaction. We analyzed data using descriptive statistics and appropriate tests for paired pre-post differences in continuous, categorical, and ranked variables. Results: Pre- and post-survey response rates were 76.1% and 69.0%, respectively. Most responded positively to the intervention, although 9.5% reported negative impressions. There was a 36% reduction (25%-50%; p<0.01 in time spent documenting and a 30% increase (11%-46%, p<0.01 in time spent in direct patient contact. No statistically significant changes were seen in job satisfaction or perception of time spent teaching. ED volume increased by 88 patients per day (32-146, p=0.04 pre- to post- and LOS was unchanged; rates of patients leaving against medical advice dropped, and rates of patients leaving without being seen increased. RVUs per hour increased 5.5% and per patient 5.3%; both were statistically significant. No statistically significant changes were seen in patients seen per hour. There was moderate correlation between changes in ED volume and changes in productivity metrics
