    Full text: The Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter was adopted after an Inter-Governmental Conference, held in London in 1972, following the principles for environmental protection enunciated in the Report of the United Nations Conference on Human Environment, held the same year in Stockholm. The IAEA has been involved since the early days of the London Convention when the Contracting Parties designated the IAEA as the competent international authority in matters related to sea disposal of radioactive waste, providing technical advice and services. The IAEA developed, for the Convention, the definition of 'radioactive wastes or radioactive matters unsuitable for dumping at sea' (e.g., high level radioactive waste) and recommended the technical basis applicable by the national authorities to issue special permits for those radioactive materials which could be dumped (mainly low and intermediate level radioactive waste, properly conditioned and 'de minimis' quantities). However, in 1985, based more on political reasons than on the existing radiation protection principles and policies, the Contracting Parties to the London Convention introduced a 'voluntary moratorium' on the disposal of low level radioactive wastes at sea, and later in 1993, a total ban of radioactive waste disposal at sea. The IAEA continues to support the objectives of the London Convention by providing scientific advice. Since 1989, at the request of the Contracting Parties, the IAEA has developed and maintained global databases on radioactive waste disposed of at sea in the past and on accidents and losses at sea involving radioactive material. The purpose of these databases is to serve as the basis for radiological impact assessment on the marine environment. The last revised reports on the above mentioned inventories were published in 1999 and in 2001 respectively. The databases are currently in the process of being updated. The paper presents

    Large quantities of low level wastes are prepared for transportation by special use vessels from each power plant to the storage facility at Rokkasho-mura in Aomori Prefecture. Large quantities of reprocessed wastes are also planned for return by similar vessels to the same place from France and the UK. In this paper the authors describe the safety assessment in hypothetical accident conditions during such mass transportation at sea. Although the possibilities of the sinking of the special use vessels as shown in figure 1 are considered to be very low on account of their double-hull structure, it is necessary to estimate the radiological risks of the transportation in order to obtain public acceptance. In this study, the following procedure is taken: (i) assumption of accident; (ii) establishment of safety assessment procedure; (iii) determination of source terms; (iv) diffusion calculation of radionuclide; (v) estimation of radiation exposure of the public

  7. Requirements of the London Convention for dumping radioactive waste at sea

    International Nuclear Information System (INIS)

    Sutton, H.C.

    1982-10-01

    This report outlines the requirements of the London Convention for dumping radioactive waste at sea and considers their scientific basis more fully. It is intended primarily as an appraisal and aid to understanding of the two documents IAEA 210 and IAEA 211, published by the International Atomic Energy Agency, and relating to the oceanographic and radiobiological basis of their definitions of high level waste and recommendations relating to its dumping at sea, which were required for London Convention purposes. The adequacy and conservation in these recommendations are considered, and the report also compares the predictions of the model on which the recommendations are based with some limited but relevant observations on radiation doses resulting from natural causes (radium in the sea), and from fallout from nuclear bomb tests. It is concluded that if dumping is carried out within the limits and according to the recommendations required by the IAEA, then it is extremely unlikely that this could lead to significant human hazard, either now or in the future. Some of the reasons for this conclusion are summarised in the final chapter

    International Nuclear Information System (INIS)

    2015-01-01

    This publication provides guidance on performing specific assessments of candidate materials for dumping at sea, to determine whether the materials are de minimis in the meaning of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter 1972 (the London Convention 1972) and the related Protocol 1996 (the London Protocol 1996). It presents a detailed radiological procedure to assess doses to workers and members of the public and doses to marine flora and fauna related to the dumping of materials at sea. The procedures in this publication follow the requirements to protect the environment in the IAEA Safety Standards and in the recommendations by the International Commission of Radiological Protection. It is expected to be used by national regulatory authorities responsible for authorizing disposal at sea of candidate materials as well as by those companies and individuals applying to obtain permission to dispose these materials at sea

  10. Determining the suitability of materials for disposal at sea under the London Convention 1972: A radiological assessment procedure

    International Nuclear Information System (INIS)

    2003-10-01

    The Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention 1972) prohibits the disposal at sea of radioactive wastes and other radioactive matter. However natural radionuclides are present in all materials, including natural and inert materials, which can also contain artificial radionuclides from anthropogenic sources such as fallout due to past atmospheric nuclear testing. Therefore, the Contracting Parties to the London Convention 1972 recognized the need to develop definitions and guidelines so that candidate materials (those wastes or other matter not otherwise prohibited from disposal at sea in accordance with Annex I to the Convention) containing less than de minimis levels of specific activity, can be regarded as 'non-radioactive' and may be disposed of at sea subject to the other provisions of the Convention. At the Nineteenth Consultative Meeting in 1997, Contracting Parties to the London Convention 1972 agreed to request the IAEA to develop further the concept of de minimis levels and, in particular, to 'provide guidance for making judgements on whether materials planned to be dumped could be exempted from radiological control or whether a specific assessment was needed' (LC 19/10, paragraph 6.31). This paragraph continues: 'The IAEA would then further be requested to provide guidance to national authorities responsible for conducting specific assessments.' The IAEA presented its advice on de minimis in IAEA-TECDOC-1068, entitled Application of Radiological Exclusion and Exemption Principles to Sea Disposal, to the Twenty-first Consultative Meeting of Contracting Parties to the London Convention 1972 in October 1999. The Contracting Parties accepted these principles and criteria and interpreted them further in the Guidelines for the Application of the De Minimis Concept Under the London Convention 1972 (the Guidelines). At that time, the Contracting Parties asked the IAEA to prepare additional guidance

    2004-01-01

    The objective of this paper is to capture the changes that are caused by the transition from nuclear operation through closure of defense nuclear facilities and convey lessons learned from their deactivation, decontamination and demolition. The specific area of discussion is focused on the planned reduction of safety equipment and consequent shift in hazard controls and safety management programs as the facility moves toward closure. The premise of the paper is that as the dominant hazards transition from nuclear to radiological and/or industrial, the facility control of the hazards and response to the potential upset conditions must transition as well to ensure safe and efficient operations. Using recent experience of the accelerated closure mission for U. S. Department of Energy (DOE) defense nuclear facilities at Rocky Flats Environmental Technology Site, the current culture with respect to developing and implementing hazard controls and response to upset conditions is illustrated. Several events have been documented that provide insight into the challenges facing line managers and safety professionals at the end of a facility's life cycle. Replacing permanent systems with temporary equipment challenges the traditional concept of reliability. Workers disassemble safety systems daily, but must rely on some of these components or redundant systems as work continues. Decisions governing upkeep of systems that await demolition balance the risk of running to failure against the cost benefit of maintenance and repair. This is further complicated as regulators and safety professionals are often unfamiliar with these new conditions and continue to view facility work activities and potential upset conditions from a nuclear operations perspective. The results of this paper evaluate the differences in how regulatory, safety basis, and operational practices must adapt to the dynamic environment of decontamination and decommissioning in contrast to the relatively constant

    Full Text Available One of the fundamental states of the sea surface is its heave. Despite of years of the intense scientific inquiry, no clear understanding of the influence of this aspect on the dynamics of the sea environment has emerged. The separation of two nearby fluid elements which one may observed for example as a free floating of small objects on the sea surface (rescuers on the rough sea or small research vessels is caused by the interaction of different components. On the other hand one may say that the heave of the sea is also a summary interaction of a few components describing the dynamics of the sea. Therefore it is the most important aspect, which influenced the dispersion phenomenon. This observation has important consequences for many different problems as for example conducting Search and Rescue missions and using unmanned ships. We would like to present results of our experiment focused on finding the answer to question about nature of the heave of the sea and its influence on safety of Unmanned Surface Vessels (USV.

    Schwarz, G.

    2016-01-01

    The Convention on Nuclear Safety (CNS) has been established after the Chernobyl accident with the primary objective of achieving and maintaining a high level of nuclear safety worldwide, through the enhancement of national measures and international cooperation. The CNS is an incentive convention. It defines the basic safety standard which shall be met by the Contracting Parties. The verification of compliance is based on a self-assessment by the Countries and a Peer Review by the other Contracting Parties. As of July 2015, there are 78 Contracting Parties. Among the Contracting Parties of the Convention are all countries operating nuclear power plants except the Islamic Republic of Iran and Taiwan, all countries constructing nuclear power plants, all countries having nuclear power plants in long term shutdown and all countries having signed contracts for the construction of nuclear power plants. The National Reports under the CNS therefore cover almost all nuclear power plants of the world. The peer review of reports, questions and answers that are exchanged in connection with the Review Meetings provided a unique overview of nuclear safety provisions and issues in countries planning or operating nuclear power plants. This is especially important for neighbouring countries to those operating nuclear power plants.

  18. Inventory of Radioactive Material Resulting from Historical Dumping, Accidents and Losses at Sea. For the Purposes of the London Convention 1972 and London Protocol 1996

    International Nuclear Information System (INIS)

    2015-10-01

    The IAEA was requested by the Contracting Parties to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention) and the 1996 Protocol (London Protocol) to develop and maintain an inventory of radioactive material entering directly into the ocean from all human made origins. The intent in producing such an inventory is to establish a record of past waste dumping and of accidents and losses at sea involving radioactive material, based on official reports, for use as an information base for the assessment of the impact of radionuclide sources in the marine environment, when deemed necessary. To respond to the request of the London Convention and Protocol, the IAEA has undertaken the development of the inventory to include radioactive waste resulting from dumping at sea, and accidents and losses which occurred at sea and involved radioactive material. The first IAEA report on this subject, Inventory of Radioactive Material Entering the Marine Environment: Sea Disposal of Radioactive Waste (IAEA-TECDOC-588), was published in 1991. The report was subsequently revised to include information provided by the Russian Federation regarding waste dumping operations conducted by the former Soviet Union in the Arctic and North-west Pacific Seas and some additional information provided by Sweden and the United Kingdom. The revised report, Inventory of Radioactive Waste Disposals at Sea (IAEA-TECDOC-1105), was published in 1999. A report on the information available at the IAEA on such incidents was published in 2001 as Inventory of Accidents and Losses at Sea Involving Radioactive Material (IAEA-TECDOC-1242). The present publication updates and combines IAEA-TECDOCs 1105 and 1242. It describes the contents of the inventory on waste dumping, accidents and losses at sea involving radioactive material. In order to prepare the publication, the IAEA, in cooperation with the International Maritime Organization (IMO), conducted a

    2002-01-01

    The catastrophic degradation of the Black Sea in a period of four decade has been the major concern of the Black Sea countries and international communities since Bucharest Convention signed in 1992. The Black Sea Region has became a challenging international arena for political scientific and socio-economic activities. Intensive international programmes and establishment of governmental and Non Governmental Organizational structures of the 1990s including Black Sea Economic Cooperation (BSEC), Black Sea Environmental Programme(BSEP), Environmental Programme for the Danube River Basin, Marine Environmental Assessment of the Black Sea Region Technical Cooperation Programme by the IAEA and establishment of the Black Sea Commission Permanent Secretariat are some of the major international efforts of the past decade that emphasizes the multi-nationality and large dimension of the Black Sea environmental management issues. The environmental degradation of the Black Sea is briefly reviewed based on the BSEP reports and data available for land based pollution sources. The environmental risk of marine vessel accidents are indicated and environmental safety concern is emphasized under the current conditions of intense energy transportation projects in the Black Sea and Caspian regions. The international policy actions, co-operation issues and scientific programmes of the past decade are overviewed with emphasis on the international achievements. Concluding remarks include the vital importance of continuation of the international commitments and sharing the political, scientific and socio-economic responsibility on the transboundary environmental pollution, rehabilitation and the safety issues of the Black Sea

    The acceleration of the globalization faces us as a nation with the challenge of adjusting our procedures and policies to accommodate foreign citizens working in Danish workplaces. In this paper I analyse data from field work voyages at sea. The data is presented in categories of bonding, bridging...... and linking acts inspired from research in social capital, and supplemented with acts of exclusion, all to describe the power conflicts which includes and excludes members in the unitary, divided or fragmented safety cultures that I met on board. The data shows that foreign seafarers are treated equally...... as long as the basic structures are not addressed. They are however treated equally on the majority´s terms, which still lead to a minority position even in the safety culture. A shared safety culture is therefore difficult to achieve....

  5. Implications of the Law of the Sea Convention

    International Nuclear Information System (INIS)

    Brewer, W.C. Jr.

    1989-01-01

    This paper reports that protection and preservation of the marine environment from wastes and toxic substances was an early concern of the Third United Nations Conference on the Law of the Sea, and the subject is extensively dealt with in the text of the Convention, adopted on 30 April 1982. The environmental provisions of the Convention are intended to serve as an umbrella treaty that states general goals, delimits the power and geographical jurisdiction of states in dealing with environmental problems, and requires states to cooperate through regional and global organizations in the development of standards. The most complex provisions of the environmental text deal with vessel discharges, reflecting the high degree of public interest in oil pollution, whereas the ocean dumping provisions rely largely on the standards of the London Dumping Convention. Pollution carried by air and rivers and wastes from seabed mining within national jurisdiction are treated briefly. The International Seabed Authority, created elsewhere in the Convention to regulate seabed mining, is granted power to regulate pollution from such mining beyond national jurisdiction. Overall, the most important contribution made by the Law of the Sea Convention to the protection of the marine environment is the obligation of states to bring national marine pollution laws up to global standards

    International Nuclear Information System (INIS)

    Hyun, Seung Gyu; Choi, Ho Seon; Kim, Sang Yun

    2008-01-01

    As of 2008, 20 nuclear power plants are under operation and six plants are under construction in Korea. NPPs account for approximately 38% of Korea's electric power production; however, it is expected that the share of power produced by NPPs will be further increased to reduce the level of CO 2 emissions, taking into account the concern over global warming. All of NPPs in Korea are located on the coast to facilitate the supply of cooling water sources. Thus, tar and other floating matters from vessels following oil spill accidents at sea may affect intake systems, and consequently interrupt the supply of cooling water. This study will review cases of response measures taken by NPPs against large-scale crude oil spill accidents that had occurred off the coast of Korea, including such accidents as the Sea Prince (July 23, 1995) and the Hebei Sprit(December 7, 2007), and relevant regulatory requirements at home and abroad

    2005-01-01

    Safety-critical software process is composed of development process, verification and validation (V and V) process and safety analysis process. Safety analysis process has been often treated as an additional process and not found in a conventional software process. But software safety analysis (SSA) is required if software is applied to a safety system, and the SSA shall be performed independently for the safety software through software development life cycle (SDLC). Of all the phases in software development, requirements engineering is generally considered to play the most critical role in determining the overall software quality. NASA data demonstrate that nearly 75% of failures found in operational software were caused by errors in the requirements. The verification process in requirements phase checks the correctness of software requirements specification, and the safety analysis process analyzes the safety-related properties in detail. In this paper, the method for safety analysis at requirements phase of software development life cycle using symbolic model verifier (SMV) is proposed. Hazard is discovered by hazard analysis and in other to use SMV for the safety analysis, the safety-related properties are expressed by computation tree logic (CTL)

    We have found that genomic diversity is generally positively correlated with abiotic and biotic stress levels (1–3). However, beyond a high-threshold level of stress, the diversity declines to a few adapted genotypes. The Dead Sea is the harshest planetary hypersaline environment (340 g·liter–1 total dissolved salts, ≈10 times sea water). Hence, the Dead Sea is an excellent natural laboratory for testing the “rise and fall” pattern of genetic diversity with stress proposed in this article. Here, we examined genomic diversity of the ascomycete fungus Aspergillus versicolor from saline, nonsaline, and hypersaline Dead Sea environments. We screened the coding and noncoding genomes of A. versicolor isolates by using >600 AFLP (amplified fragment length polymorphism) markers (equal to loci). Genomic diversity was positively correlated with stress, culminating in the Dead Sea surface but dropped drastically in 50- to 280-m-deep seawater. The genomic diversity pattern paralleled the pattern of sexual reproduction of fungal species across the same southward gradient of increasing stress in Israel. This parallel may suggest that diversity and sex are intertwined intimately according to the rise and fall pattern and adaptively selected by natural selection in fungal genome evolution. Future large-scale verification in micromycetes will define further the trajectories of diversity and sex in the rise and fall pattern. PMID:14645702

    1999-08-01

    The IAEA was requested by the Contracting Parties to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention 1972) to develop and maintain an inventory of radioactive material entering the marine environment from all sources. The rationale for having such an inventory is related to its use as an information base with which the impact of radionuclides from different sources entering the marine environment can be assessed and compared. To respond to the request of the London Convention, the IAEA has undertaken the development of the inventory to include: disposal at sea of radioactive wastes, and accidents and losses at sea involving radioactive materials. This report addresses disposal at sea of radioactive waste, a practice which continued from 1946 to 1993. It is a revision of IAEA-TECDOC-588, Inventory of Radioactive Material Entering the Marine Environment: Sea Disposal of Radioactive Waste, published in 1991. In addition to the data already published in IAEA-TECDOC-588, the present publication includes detailed official information on sea disposal operations carried out by the former Soviet Union and the Russian Federation provided in 1993 as well as additional information provided by Sweden in 1992 and the United Kingdom in 1997 and 1998

    The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management, hereinafter referred to as the 'Joint Convention', is the result of international discussions that followed the adoption of the Convention on Nuclear Safety, in 1994. France signed the Joint Convention at the General Conference of the International Atomic Energy Agency (IAEA) held on 29 September 1997, the very first day the Joint Convention was opened for signature. She approved it on 22 February 2000 and filed the corresponding instruments with the IAEA on 27 April 2000. The Joint Convention entered into force on 18 June 2001. For many years, France has been taking an active part in the pursuit of international actions to reinforce nuclear safety and considers the Joint Convention to be a key step in that direction. The fields covered by the Joint Convention have long been part of the French approach to nuclear safety. This report is the fourth of its kind. It is published in accordance with Article 32 of the Joint Convention and presents the measures taken by France to meet each of her obligations set out in the Convention. The facilities and radioactive materials covered by the Joint Convention are much diversified in nature and are controlled in France by different regulatory authorities (see Section E). Over and above a specific threshold of radioactive content, a facility is referred to as a 'basic nuclear facility' (installation nucleaire de base - INB) and placed under the control of the French Nuclear Safety Authority (Autorite de surete nucleaire - ASN). Below that threshold and provided that the facility involved falls under a category of the nomenclature of classified facilities for other purposes than their radioactive materials, any facility may be considered as a 'classified facility on environmental-protection grounds' (installation classee pour la protection de l'environnement - ICPE) and placed under the control of the Ministry for the

    The aim of this study was to investigate patients' and families' perspectives of safety and quality in the setting of a life-limiting illness. Data reported here were generated from a qualitative study using video-reflexive ethnographic methodology. Data were collected over 18 months and generated through participant observation, shadowing of clinicians, field-interviews and semi-structured interviews with patients and families. The study was conducted at two hospital sites in Sydney, Australia and in patients' homes. Patients with an advanced life-limiting illness (n = 29) ranging in age between 27 and 89 years and family members (n = 5) participated in the study. Patient safety remains important to dying patients and families. For dying people, iatrogenic harm is not regarded as 'one off' incidents. Rather, harm is experienced as a result of an unfolding series of negative events. Critically, iatrogenic harm is emotional, social and spiritual and not solely technical-clinical misadventure and is inextricably linked with feeling unsafe. Thus, patient safety extends beyond narrowly defined technical-clinical parameters to include interpersonal safety. Current approaches to patient safety do not address fully the needs of dying patients and their families. Patients and their families regard poor communication with and by health professionals to be harmful in and of itself. © The Author 2015.

    2002-01-01

    The Convention on Nuclear Safety is considered as a part of the overall nuclear safety regime. That regime has many components, but they all have one single objective - to make sure that safety is at as high a level as possible. The Convention is a living process, a process which should eventually lead to increasingly greater safety. The Meting has focused on a number of issues that are also priorities for the Agency; one such issue is safety culture. The effectiveness and transparency are key issues. A second issue which is highlighted is management of nuclear knowledge. Other high priority issues which were identified include: planned life extension; the need during life extension to look into the ageing of equipment and structures; deregulation and its impact on safety; and the question of periodic safety reviews. The question of co-operation between regulatory bodies is one that was given emphasis to over the last few years. It is very important that there be exchange of experience and exchange of expertise between regulatory bodies, and between the manufacturers of power reactors and the countries where the reactors are operated. Also of importance in terms of international co-operation is the development of adequate emergency response everywhere. A major point that which is left to the participating countries is that although safety is a national responsibility - there is absolutely no question about that -many issues need international co-operation

  10. The reality of life safety consequence classification

    International Nuclear Information System (INIS)

    Hartford, D.N.D.; Assaf, H.; Kerr, I.R.

    1999-01-01

    Because empirical methods of consequence estimation were not designed for application in risk analysis for dam safety, BC Hydro developed its own method for determining loss of life due to dam failures as part of the development of the risk analysis process. Because loss of life estimation for consequence classification entails the generation of essentially the same information, the method can also be used to determine the consequence category of the dam for life safety considerations, and the model can be extended to third party property damage. The methodology adopted for dealing with life safety differs considerably from the empirical approach by modelling the response of the downstream population to a dam failure flood. The algorithm simulates the response of various groups of populations to the warnings of dam failure and the physical process of fleeing from the areas of potential innundation. Assessing the life safety consequences of dam failure is a first step in estimating dam safety in terms of CDA Guidelines, and empirical methods in use are not suitable for determining loss of life due to dam failures. The process described herein is the only physically based method available for estimating loss of life due to dam failures required by the Dam Safety Guidelines. The model is transparent, logically sound, and has been peer reviewed. The method provides a rational basis for the first step in performing safety assessments of dams in terms of the Guidelines, particularly high consequence dams. 8 refs., 3 figs

  11. Sweden's second national report under the Convention on nuclear safety. Swedish implementation of the obligations of the Convention

    2001-01-01

    organisations, such as downsizing, outsourcing and merging, need to be followed closely, by the licensees as well as by the regulatory bodies, and methods need to be further developed to assess the safety consequences of such changes. The ongoing dialogue between the licensees and the regulator regarding development of safety in existing reactors needs to be concluded, in order to define reasonable requirements for back-fitting during the remaining operating time. The general concern expressed in the first report to the Convention about the shortage of qualified, university trained engineers and researchers in specific nuclear fields, still remains in the longer perspective. A plan is also under discussion to ensure financing of nuclear education and research at several universities for at least a three year period. Taking into account all these efforts, an action plan should be developed to ensure the necessary long-term nuclear competence in Sweden. At the first review meeting in April 1999, Sweden accepted to report on the following issues in particular, in its next report: 1. measures to upgrade the older reactors and how these comply with the safety regulations, 2. measures within the industry and the regulatory bodies to improve the safety culture, 3. monitoring of the effects, if any, on safety as a consequence of deregulation of the electricity market, 4. experience gained from the new safety regulations, especially with regard to the higher requirements placed on the licensees own control over safety. These reports do not indicate any concerns as to the Swedish compliance with the obligations under the Convention

  12. Sweden's third national report under the the Convention on Nuclear Safety. Swedish implementation of the obligations of the Convention

    International Nuclear Information System (INIS)

    2004-01-01

    The national reports to the review meetings according to Article 5 of the Convention call for a self-assessment of each Contracting Party with regard to compliance with the obligations of the Convention. For Sweden this self-assessment has demonstrated full compliance with all the obligations of the Convention, as shown in detail in part B of this national report. There is an open and constructive dialogue between the regulatory bodies and the licensees. The owner companies are well established with good corporate financial records. They demonstrate a commitment to maintain a high level of safety in their nuclear power plants. Not withstanding the increased competition, the licensees continue to co-operate in solving important safety issues. The regulators in Sweden are assessed as well qualified for their tasks and their resources have been maintained. The international co-operation networks of both regulators and utilities are well developed. From the safety and environmental impact point of view, the Swedish nuclear power plants are competitive internationally. However, Sweden would like to point out the following issues, where further development should be given special attention in relation to the obligations under the Convention: The compatibility of the Act on Nuclear Activities with the Environmental Code needs to be followed up in order to assure that the licensing process is fully consistent. The future supply of radiation protection specialists needs to be further investigated and measures may need to be taken, as has been done to ensure the supply or nuclear safety specialists. The ongoing concentration of vendors and service companies needs to be assessed, from the safety and availability point of view, and the licensees may need to implement their own joint solutions if the market can not supply the necessary services at acceptable conditions. The operating organisations need to assess their consolidation after several organisational changes following

    SeaRAM is a multi-year Department of Energy (DOE) project designed to validate the safety of shipping radioactive materials (RAM) by sea. The project has an ultimate goal of developing and demonstrating analytic tools for performing comprehensive analyses to evaluate the risks to humans and the environment due to sea transport of plutonium, vitrified high-level waste (VHLW), and spent fuel associated with reprocessing and research reactors. To achieve this end, evaluations of maritime databases and structural an thermal analyses of particular severe collision and fire accidents have been and will continue to be conducted. Program management for SeaRAM is based at the DOE's Office of Environmental Restoration. Technical activities for the project are being conducted at Sandia National Laboratories (SNL). Several private organizations are also involved in providing technical support, notably Engineering Computer Optecnomics, Inc. (ECO). The technical work performed for SeaRAM also supports DOE participation in an International Atomic Energy Agency (IAEA) Cooperative Research Program (CRP) entitled Accident Severity at Sea During Transport of Radioactive Material. This paper discusses activities performed during the first year of the project

    2004-01-01

    The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management (the Joint Convention) is the only legally binding international treaty in the area of radioactive waste management. It was adopted by a Diplomatic Conference in September 1997 and opened for signature on 29 September 1997. The Convention entered into force on 18 June 1998, and to date (September 04) has been signed by 42 States, of which 34 have formally ratified, thus becoming Contracting Parties. The Joint Convention applies to spent fuel and radioactive waste resulting from civilian application. Its principal aim is to achieve and maintain a high degree of safety in their management worldwide. The Convention is an incentive instrument, not designed to ensure fulfillment of obligations through control and sanction, but by a peer pressure. The obligations of the Contracting Parties are mainly based on the international safety standards developed by the IAEA in past decades. The Convention is intended for all countries generating radioactive waste. Therefore it is relevant not only for those using nuclear power, but for any country where application of nuclear energy in medicine, conventional industry and research is currently used. Obligations of Contracting Parties include attending periodic Review Meetings and prepare National Reports for review by the other Contracting Parties. The National Reports should describe how the country is complying with the requirements of the Articles of the Convention. The first such meeting was held at the IAEA headquarters in November 2003. This paper will describe the origin of the Convention, present its content, the expected outcome for the worldwide safety, and the benefits for a country to be part of it

    The adoption of the 1994 Nuclear Safety Convention should not affect Spanish law. Nevertheless, the coming into force of the Nuclear Safety Convention in Spain will represent an opportunity for Spanish nuclear authorities to clarify one of the aspects of the Spanish nuclear legislation that has become oldfashioned. It would be important to adopt a general rule on nuclear safety which, at the highest level, would clearly establish the prerequisites which have to be fulfilled in order to get a licence as well as the competences of the supervision authorities, including the (criminal and) administrative penalties that can be imposed.

    Full Text Available As is well known, there is no international convention for the carriage of goods in general. Each mode of transport counts on one or several international conventions that specifically regulate the provision of international transport by sea, rail, road or air. Thus, multimodal freight transport are characterised by a patchwork of different legal regimes that represents a huge challenge for the growth of multimodal transport industry. The paper aims to analyse the latest, but still not in force Convention on Contracts for the International Carriage of Goods Wholly or Partly by Sea (the Rotterdam rules that should provide global solution for multimodal carrier liability. Comparison of the carrier’s liability in the former conventions relating to the international carriage of goods by sea and other rules are also discussed.

  1. Life cycle models of conventional and alternative-fueled automobiles

    Science.gov (United States)

    Maclean, Heather Louise

    This thesis reports life cycle inventories of internal combustion engine automobiles with feasible near term fuel/engine combinations. These combinations include unleaded gasoline, California Phase 2 Reformulated Gasoline, alcohol and gasoline blends (85 percent methanol or ethanol combined with 15 percent gasoline), and compressed natural gas in spark ignition direct and indirect injection engines. Additionally, I consider neat methanol and neat ethanol in spark ignition direct injection engines and diesel fuel in compression ignition direct and indirect injection engines. I investigate the potential of the above options to have a lower environmental impact than conventional gasoline-fueled automobiles, while still retaining comparable pricing and consumer benefits. More broadly, the objective is to assess whether the use of any of the alternative systems will help to lead to the goal of a more sustainable personal transportation system. The principal tool is the Economic Input-Output Life Cycle Analysis model which includes inventories of economic data, environmental discharges, and resource use. I develop a life cycle assessment framework to assemble the array of data generated by the model into three aggregate assessment parameters; economics, externalities, and vehicle attributes. The first step is to develop a set of 'comparable cars' with the alternative fuel/engine combinations, based on characteristics of a conventional 1998 gasoline-fueled Ford Taurus sedan, the baseline vehicle for the analyses. I calculate the assessment parameters assuming that these comparable cars can attain the potential thermal efficiencies estimated by experts for each fuel/engine combination. To a first approximation, there are no significant differences in the assessment parameters for the vehicle manufacture, service, fixed costs, and the end-of-life for any of the options. However, there are differences in the vehicle operation life cycle components and the state of technology

Recent surveyed records of the exposed doses of workers who engaged in sea transport operation indicate that exposed doses of transport workers are significantly low. Measured distribution of the exposed dose equivalents inboard those vessels indicates that dose rate equivalents inside those vessels are lower than levels regulated by the transport regulations of Japan. These facts clarify that radiation safety of inboard environment and handling of transport casks in sea transport of radioactive material in Japan are assured

    The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management (the Joint Convention) is the first legally binding international treaty in the area of radioactive material management. It was adopted by a Diplomatic Conference in September 1997 and opened for signature on 29 September 1997. The Convention entered into force on 18 June 1998, and to date (May 2006) has been ratified by 41 countries. The Joint Convention applies to spent fuel and radioactive waste resulting from civilian application. Its principal aim is to achieve and maintain a high degree of safety in their management worldwide. The Convention is an incentive instrument, not designed to ensure fulfilment of obligations through control and sanction, but by a volunteer peer review mechanism. The obligations of the Contracting Parties are mainly based on the international safety standards developed by the IAEA in past decades. The Convention is of interest of all countries generating radioactive waste. Therefore it is relevant not only for those using nuclear power, but for any country where application of nuclear energy in education, agriculture, medicine and industry is currently used. Obligations of Contracting Parties include attending a Review Meeting held every three years and prepare National Reports for review by the other Contracting Parties. In the National Reports basic information on inventory and facilities for management of radioactive materials has to be provided. Countries with small nuclear power and/or research programs or countries having radioactive materials only from nuclear application on medicine, agriculture or conventional industry, can benefit from the exchange of information and the technical knowledge gained by the reporting procedure set up by the Convention. The second Review Meeting is to be held at IAEA headquarters from 15 to 26 May 2006. This paper presents the objectives and the implementation status of the Convention, the

    identified that require special attention, particularly, with regard to safety management, safety culture, plant ageing, upgrading and effectiveness of regulatory practices, as well as maintaining competence and knowledge in the industry, regulatory bodies and research institutions. The review process highlighted factors and circumstances, external to nuclear safety as such, which nevertheless may impact on nuclear safety. Contracting Parties were invited to provide further information in their next national reports on maintaining competence and motivation of staff needed for safe regulation and operation of nuclear installation. Since the 1999 Review Meeting, several Contracting Parties have restructured their regulatory bodies and adopted new legislation or improved existing legislation to more closely meet the requirements of the Convention. Examples of areas of new legislation are: establishing independent regulatory bodies; emergency preparedness; decommissioning; and radiation protection provisions consistent with the International Commission on Radiological Protection's 1990 Recommendations (ICRP 60) and the International Basic Safety Standards published by the IAEA (BSS). Full implementation of the ICRP 60 recommendations and BSS is not complete in some countries. Contracting Parties reported on their individual national regulatory strategies. Some Contracting Parties use probabilistic safety assessment (PSA) as an additional tool in optimizing their regulatory or inspection activities, and some use performance indicators, whether they be quantitative or qualitative, to monitor the safety of their nuclear installations. In discussions, comparison was made of the advantages and disadvantages of regulations that are detailed and prescriptive in nature as compared to less prescriptive, goal-oriented approaches and the complementary use of risk assessments.

    The innovative approach of the Convention, which is based on incentive after than legal binding, had been considered successful in strengthening the nuclear safety worldwide. However, the nuclear accident at the Fukushima Dai-ichi Nuclear Power Plant (Japan) in March 2011 has exposed a number of weaknesses of the Convention. Given that context, this paper will analyse the characteristics of the CNS in order to understand the advantages and disadvantages of the Convention, and finally to suggest some possible improvements. The analysis in this paper shows that the incentive approach of the CNS has succeeded in facilitating the active roles of its Contracting Parties in making the National Reports and participating in the peer review of these reports. However, the incoherent quality of the National Reports, the different level of participation in the peer review process by different Contracting Parties, and the lack of transparency of the peer review have undermined the effectiveness of the Convention in strengthening the international safety regime as well as preventing serious regulatory errors that had happened in Japan before the Fukushima accident. Therefore, the peer review process should be reformed into a more transparent and independent direction, while an advisory group of regulators within the CNS might also be useful in improving the effectiveness of the Convention as already proven by the good practice in the European Union. Only with such effective change, the CNS can maintain its pivotal role in the international safety regime

    This paper discusses the implementation of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management. The Joint Convention: establishes a commitment with respect to safe management of spent nuclear fuel and radioactive waste; requires the Parties to ''take appropriate steps'' to ensure the safety of their spent fuel and waste management activities, but does not delineate standards the Parties must meet; and seeks to attain, through its Contracting Parties, a higher level of safety with respect to management of their spent nuclear fuel, disused sealed sources, and radioactive waste

  10. Sweden's fourth national report under the Convention on Nuclear Safety. Swedish implementation of the obligations of the Convention

    International Nuclear Information System (INIS)

    2007-01-01

    The national reports to the review meetings according to Article 5 of the Convention call for a self-assessment of each Contracting Party with regard to compliance with the obligations of the Convention. For Sweden this self-assessment has demonstrated compliance with all the obligations of the Convention, as shown in part B of this national report. The Swedish existing nuclear power programme is currently under strong development since a few years. Large amounts are being invested in the 10 remaining operating reactors to prepare for long term operation. The licensees as well as the regulatory bodies have also been challenged over the last years by events, especially the Forsmark event in July 2006, demonstrating the importance of having strong safety management in place and maintaining of a vital safety culture. Of particular importance is not only to develop good formal management systems, but also to monitor and follow up how the systems function in the daily work at the plants. The need for this attention is reinforced by the major programmes going on during a limited time period to upgrade and uprate the plants. These programmes will require a full effort of the operating organisations as well as of the regulatory bodies. An additional challenge is, during the same time period, to manage the transfer of knowledge to a new generation of engineers and specialists. A large number of key staff is due to retire within the next 10 years. The generally positive impression reported to earlier review meetings under the Convention still stands. Therefore, Sweden would like to point out the following as strong features in its national nuclear practice: The Swedish legal framework is well developed and the responsibility for safety is very well defined. The nuclear law also provides for public insight into the activities of the licensees. The regulatory bodies have maintained and increased their resources and are further developing their regulatory practices. There is an

    The nuclear programme in Argentina includes: nuclear power and related supplies, medical and industrial applications, waste management, research and development and human training. Nuclear facilities require life management programs that allow a safe operation. Safety is the first priority for designers and operators. This can be attained with defence in depth: regular inspections and maintenance procedures to minimize failure risks. CNEA objectives in this area are to possess the necessary capability to give safe and fast technical support. Within this scheme, one of the main activities undertaken by CNEA is to provide technological assistance to the nuclear plants and research reactors. As a consequence of an increasing concern about safety and ageing a Life Management Department for safe operation was created to take care of these subjects. The goal is to elaborate a Safety Evaluation Process for the critical components of nuclear plants and other facilities. The overall objectives of a safety process are to ensure a continuous safe, reliable and effective operation of nuclear facilities and it means the implementation of the defence in deep concept to enhance safety for the protection of the public, the workers and the environment.

  13. Impact of mandibular conventional denture and overdenture on quality of life and masticatory efficiency

    Directory of Open Access Journals (Sweden)

    Rachel Gomes CARDOSO

    Full Text Available Abstract The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wearing bimaxillary conventional dentures, for at least one year, were recruited. The patients were then assigned to either two treatment groups: mandibular overdentures supported by two implants with bar-clip system and a maxillary conventional denture (n = 25, and new maxillary and mandibular conventional complete dentures (n = 25. Masticatory efficiency and oral health-related quality of life were assessed before and 3 months after denture insertion. The Brazilian version of OHIP-Edent questionnaire was used to assess the oral health-related quality of life. Masticatory efficiency was evaluated with chewing capsules through a colorimetric method. The results revealed fewer oral health–related quality of life problems in patients wearing mandibular two-implant overdentures compared to the conventional dentures group. In addition, the implant overdenture group presented statistically significant improvement in masticatory efficiency (p = 0.001. There was no correlation between masticatory efficiency and OHIP in the implant group (p > 0.05, however a correlation was found in the conventional denture group (p < 0.05. Therefore, these short-term results suggest that mandibular overdenture retained by 2 implants with immediate loading combined with maxillary conventional dentures provide better masticatory efficiency and oral health–related quality of life than mandibular conventional dentures.

    2010-01-01

    It was more than 20 years ago that IAEA discussed the issue pertaining to the need in scientific and engineering support to the regulatory body. The Convention on Nuclear Safety being the keystone in assurance of the global nuclear safety and security regime was adopted in 1994. It is pointed out that two independent organizations supervised by Rostechnadzor have been established within the Russian TSO system, FSUE VO 'Safety' being one of them. The tasks of the organization comprise obligatory certification of equipment as well as acceptance of equipment before its delivery to the NPP both in Russia and in the countries constructing the power units based on the Russian designs. The acceptance procedure has been set forth in the new Russian document at the level of the federal rules and regulations for nuclear safety assurance. As far as its implementation decision is concerned, a task for selection and training of personnel has been set and allocated on the Training and Methodological Center of Nuclear and Radiation Safety established with the support of FSUE VO 'Safety', which provides training programmes and specific lecture courses in the wide range of the relevant topics.

    The return of vitrified high level waste arising from the reprocessing of spent nuclear fuel at Sellafield to continental Europe, e.g. Germany, will start around the end of the century. The shipment of the specific flasks will include transportation via the Irish Sea, the English Channel and the North Sea with ships of the Pacific Nuclear Transport Limited (PNTL) classified to the INF 3 standard. The assessment approach is to analyse the severity and the frequency of mechanical impacts, fires and explosions with the potential to affect the package. The results show that there is a high safety margin due to the special safety features of the INF 3 ships compared to conventional ships. The remaining accident probability for a trans-port of vitrified high level waste from UK to the continent is very low. No realistic severe accident scenarios that could seriously affect the flasks and could lead to a radioactivity re-lease have been identified. (author)

    The ships carrying irradiated nuclear fuel, plutonium and high level radioactive wastes(INF materials) are designed to keep integrity of packaging based on the various safety and fireproof measures, even if the ship encounters a maritime fire accident. However, granted that the frequency is very low, realistic severe accidents should be evaluated. In this paper, probabilistic safety assessment method is applied to evaluate safety margin for severe sea fire accidents using event tree analysis. Based on our separate studies, the severest scenario was estimated as follows; an INF transport ship collides with oil tanker and induces a sea surface fire. Probability data such as ship's collision, oil leakage, ignition, escape from fire region, operations of cask cooling system and water flooding systems were also introduced from above mentioned studies. The results indicate that the probability of which packages cannot keep their integrity during the sea surface fire accident is very low and sea transport of INF materials is carried out very safely.

    2011-01-01

    The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) is the first and the only legally binding international instrument to address safety issues concerning the management of spent fuel and radioactive waste on a global scale. It entered into force on June 18, 2001. The Government of Canada strongly supported international efforts to bring into force the Joint Convention and was the second country to ratify it. The Joint Convention is an 'incentive instrument' that is based on peer review (similar in that respect to the Convention on Nuclear Safety) and devised to encourage countries that are Contracting Parties to report and to foster open and frank discussions on the safety of spent fuel and radioactive waste management. Being an incentive convention, it is not designed to mandate Contracting Parties to fulfill its obligation through control and sanction, but it is based on the common objectives of Contracting Parties to achieve and maintain a high level of safety in spent fuel and radioactive waste management, protect individuals, society and the environment from ionizing radiation and prevent accidents and if necessary mitigating the consequences of such accidents. The following paper will provide an introduction to the Joint Convention and provide a summary of Canada's peer review at the most recent Review Meeting which was held on May 11-20, 2009, at the International Atomic Energy Agency (IAEA) headquarters in Vienna, Austria.

  5. A Critical Analysis of the Conventionally Employed Creep Lifing Methods.

    2014-04-29

    The deformation of structural alloys presents problems for power plants and aerospace applications due to the demand for elevated temperatures for higher efficiencies and reductions in greenhouse gas emissions. The materials used in such applications experience harsh environments which may lead to deformation and failure of critical components. To avoid such catastrophic failures and also increase efficiency, future designs must utilise novel/improved alloy systems with enhanced temperature capability. In recognising this issue, a detailed understanding of creep is essential for the success of these designs by ensuring components do not experience excessive deformation which may ultimately lead to failure. To achieve this, a variety of parametric methods have been developed to quantify creep and creep fracture in high temperature applications. This study reviews a number of well-known traditionally employed creep lifing methods with some more recent approaches also included. The first section of this paper focuses on predicting the long-term creep rupture properties which is an area of interest for the power generation sector. The second section looks at pre-defined strains and the re-production of full creep curves based on available data which is pertinent to the aerospace industry where components are replaced before failure.

    Full Text Available Given the remarkable increase of public interest in organic food products, it is indeed critical to evaluate the microbiological risk associated with consumption of fresh organic produce. Organic farming practices including the use of animal manures may increase the risk of microbiological contamination as manure can act as a vehicle for transmission of foodborne pathogens. This study aimed to determine and compare the microbiological status between organic and conventional fresh produce at the retail level in Malaysia. A total of 152 organic and conventional vegetables were purchased at retail markets in Malaysia. Samples were analyzed for mesophilic aerobic bacteria, yeasts and molds, and total coliforms using conventional microbiological methods. Combination methods of most probable number-multiplex polymerase chain reaction (MPN-mPCR were used to detect and quantify foodborne pathogens, including Escherichia coli O157:H7, Shiga toxin-producing E. coli (STEC, Listeria monocytogenes, Salmonella Typhimurium, and Salmonella Enteritidis. Results indicated that most types of organic and conventional vegetables possessed similar microbial count (P > 0.05 of mesophilic aerobic bacteria, yeasts and molds, and total coliforms. E. coli O157:H7 and S. Typhimurium were not detected in any sample analyzed in this study. Among the 152 samples tested, only the conventional lettuce and organic carrot were tested positive for STEC and S. Enteritidis, respectively. L. monocytogenes were more frequently detected in both organic (9.1% and conventional vegetables (2.7% as compared to E. coli O157:H7, S. Typhimurium, and S. Enteritidis. Overall, no trend was shown that either organically or conventionally grown vegetables have posed greater microbiological risks. These findings indicated that one particular type of farming practices would not affect the microbiological profiles of fresh produce.

    2003-01-01

    Full text: The sea is the key and essential element of the basin although the bigger share of the basin consists of the river ecosystems. The classical theory of sustainable basin development implies that the one of the main indicator of sustainable development is the river ecosystem biodiversity and especially the sturgeon kind of fish with long life cycle. The fish biodiversity and stocks of valuable fish were totally destroyed. One of the most serious causes for that was the inadequate water policy aimed at the construction of the river dam complexes and the construction of the huge water reservoirs. These water reservoirs were used for different purposes, but the main danger is coming from their usage as nuclear power plant cooling ponds. The wide public has received the opportunity to learn about the ecological danger of such objects. The modern Russian society doesn't fully believe to the results of monitoring by state agencies. In order to propel these activities the creation of non-governmental ecological organizations is needed within the all the key elements of river ecosystems. The information skeleton throughout the whole basin needed for successful and effective functioning of these organizations can be constructed only under the condition of having good and modern means of communication such as electronic ones (e-mail, Internet) and publishing of own newspapers and bulletins. Our regional non-governmental organization has created already such a network within the Don and accepting existing local organizations as members. The activities on the creation of the same networks have been already induced in the Volga and Ural rivers basins. Now the networks are more or less shaped and we start equipping the local NGOs with radiation detection devices of 'Inspector'class for measuring the beta and gamma radiation. Having the needed experts and specialists the independent networked organizations will be able not only to monitor the radiological situation

    The societal acceptance of various risks is analyzed and rules of risk acceptance as a function of different parameters (e. g., expected benefit, intensity of effect) are spelled out. The monetary value of a human life is estimated, based on investments in safety of different human activities. The acceptable risks and safety investments in different human activities are then compared with risks and safety investments of the nuclear industry. Safety investments required to reduce radioactivity releases and risks from nuclear power stations to ALAP (as low as practiable) levels are taken as a study case. It is found that risks in the nuclear industry are several orders of magnitude lower and safety investments per human life saved are several orders of magnitude higher, as compared with risks and safety investments in other human activities

  9. Safety aspects in life extension of NPPs. Working material

    International Nuclear Information System (INIS)

    2002-01-01

    Due to current social and economical framework, in last years many Member States (MS) started a process of Plant Life Extension (PLEX) for their older nuclear facilities. The process followed many different approaches, being intrinsically dependent on the national regulatory framework and technical tradition. This process has many nuclear safety implications, other than strategic and political ones, and therefore a need for tailoring the available safety assessment tools to such applications has become urgent in recent years. Typical safety assessment processes such as the Periodic Safety Review has been used already and can be used in the future as a framework for a PLEX. Also the review of regular maintenance and ageing management programs and the continuous upgrading of the Safety Analysis Report are tools widely used in a life extension context in many MS. However, recently some MS highlighted the need to identify in a clear way the technical aspects more directly affecting the decision for a long-term operation of a nuclear facility. Many Technical Cooperation projects have been requested for the year 2003-2004 on this subject and a generic task in Nuclear Safety proved necessary as a background activity. Therefore, on May 6-10, 2002, a Consultant Meeting dealing with Safety Aspects of life extension for NPPs was convened at the Nuclear Safety Dept. of the IAEA. It was attended by representatives of Regulatory Bodies and Utilities, both from countries with experience of life extension of NPPs and countries where the process is at the beginning. The main application problems were identified and discussed and a first attempt was carried out to define the key elements of the life extension process, isolating peculiar technical items, LTO related, from generic safety related tasks. The result was a preliminary technical document with a collection of basic experience and information for the implementation of a PLEX program. Therefore the draft document was thought

  14. The IAEA nuclear safety conventions: an example of successful ''treaty management''?

    International Nuclear Information System (INIS)

    2003-01-01

    The nuclear safety conventions represent an advance in bringing national nuclear power activities within the ambition of international legal safety norms. They introduce a novel measure of international legal accountability for the safety of commercial nuclear power operations. But whether this system represents a successful example of treaty management defies an easy answer. Certainly, it is beyond doubt that the peer review process combines aspects of law application(enforcement/control of implementation and compliance) with lawmaking. The nuclear safety convention bear the characteristics of a political compromise that affects effectiveness. For the time being it remains unclear whether this compromise will prove acceptable in the long run or how the tension between the two contending perspectives is likely to resolve itself. (N.C.)

    2009-01-01

    The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management, referred to as the 'Joint Convention', is the result of international discussions that followed the adoption of the Convention on Nuclear Safety, in 1994. France signed the Joint Convention at the General Conference of the International Atomic Energy Agency (IAEA) held on 29 September 1997, the very first day the Joint Convention was opened for signature. She approved it on 22 February 2000 and filed the corresponding instruments with the IAEA on 27 April 2000. The Joint Convention entered into force on 18 June 2001. For many years, France has been taking an active part in the pursuit of international actions to reinforce nuclear safety and considers the Joint Convention to be a key step in that direction. The fields covered by the Joint Convention have long been part of the French approach to nuclear safety. For his third report, France presented a document reflecting the viewpoints of the various stakeholders (regulatory authorities and operators). Thus, for each of the chapters in which the regulatory authority is not the only party to express its point of view, a three-stage structure was adopted: first of all a description by the regulatory authority of the regulations, followed by a presentation by the operators of the steps taken to meet the regulations and finally, an analysis by the regulatory authority of the steps taken by the operators. This third report was distributed in October 2008 to all Contracting Parties who asked 213 questions on the French report. France answered each of them in the present document

It is also shown that the incremental safety investments needed to further reduce the radiation doses in the environment during normal and continuous operation of nuclear plants are extravagantly high as compared to safety investments in other human activities and in other facets of human life. Considering that there is a limit to the economic means available, societal expenditures for reducing risks should by spread, as much as possible, over all human activities to get the maximum return from investments.

    The sea transport of fresh MOX fuel from Europe to Japan is under planning. For the structure and equipment of transport ships for fresh MOX fuels, there is a special safety standard called the INF Code of IMO (International Maritime Organization). For transport of radioactive materials, there is a safety standard stipulated in Regulations for the Safe Transport of Radioactive Material issued by IAEA (International Atomic Energy Agency). Under those code and standard, fresh MOX fuel will be transported safely on the sea. However, a dose assessment has been made by assuming that a fresh MOX fuel package might be sunk into the sea by unexpected reasons. In the both cases for a package sunk at the coastal region and for that sunk at the ocean, the evaluated result of the dose equivalent by radiation exposure to the public are far below the dose equivalent limit of the ICRP recommendation (1 mSv/year).

    Full Text Available Replenishment at sea is a process which plays the key role in the contemporary naval logistics during military and crisis operations. As the last element of the supply chain, it must use specific standards within the areas of procedures, technical equipment, logistic assets and resources, as well as safety, especially in multinational operations. The methods applied enable ships to operate at sea in the long term without logistic support provided by sea ports. The paper explains all the methods of the solids and liquids replenishment, and also gives an idea how to estimate the resupply process, using the measures. The level of standardization of procedures and assets implemented by NATO, the EU and other willing states has been described.

  4. The Evolution of System Safety at NASA

    Science.gov (United States)

    Dezfuli, Homayoon; Everett, Chris; Groen, Frank

    2014-01-01

    The NASA system safety framework is in the process of change, motivated by the desire to promote an objectives-driven approach to system safety that explicitly focuses system safety efforts on system-level safety performance, and serves to unify, in a purposeful manner, safety-related activities that otherwise might be done in a way that results in gaps, redundancies, or unnecessary work. An objectives-driven approach to system safety affords more flexibility to determine, on a system-specific basis, the means by which adequate safety is achieved and verified. Such flexibility and efficiency is becoming increasingly important in the face of evolving engineering modalities and acquisition models, where, for example, NASA will increasingly rely on commercial providers for transportation services to low-earth orbit. A key element of this objectives-driven approach is the use of the risk-informed safety case (RISC): a structured argument, supported by a body of evidence, that provides a compelling, comprehensible and valid case that a system is or will be adequately safe for a given application in a given environment. The RISC addresses each of the objectives defined for the system, providing a rational basis for making informed risk acceptance decisions at relevant decision points in the system life cycle.

    After a short description of Switzerland as a state in the middle of Europe and of its political organization, the report explains the development of the nuclear power from the first experimental reactor in 1957. Presently five nuclear power plants (NPP) are operating in Switzerland, producing about 40% of the electricity consumption of the country, the rest being produced essentially by hydroelectric plants. As the first regulatory authority, the Swiss Federal Nuclear Safety Commission was set up in 1960, which evolved to the Swiss Nuclear Safety Inspectorate (ENSI). Switzerland signed the Convention on Nuclear Safety (CNS) which came into force at the end of 1996. Since there, Switzerland has prepared and submitted the country reports for the regular Review Meetings of Contracting Countries. This 6th report by ENSI provides an update on compliance with CNS obligations. It gives consideration to issues that aroused particular interest at the 5th meeting and at the extraordinary meeting dedicated to the consequences of the accident at Fukushima Daiichi. Shortly after the accident at Fukushima Daiichi, the Swiss government has decided to phase out nuclear energy; existing plants will continue to operate as long as they are safe. In Switzerland, on-going activities regarding safety assessment of the different stages in the lifetime of nuclear installations consist of periodic assessments and assessments of long-term operation for existing Swiss NPPs. Such assessments have been performed for two Swiss NPPs (Beznau NPP and Muehleberg NPP) which have been in commercial operation for over 40 years. A detailed examination demonstrated that the conditions for the taking out of service of an NPP are not and will not be reached by these two plants within the next 10 years. Nevertheless, it is mandatory to continue with the scheduled ageing management, maintenance and backfitting activities. After the Fukushima accident, additional safety reviews were performed.

    The International Linear Collider (ILC) is a proposed high-energy collider consisting of two linear accelerators, two dumping rings, electron and positron sources, and a single colliding hall with two detectors. The total length and CMS energy of the ILC will be 31 km and 500 GeV, respectively (and 50 km and 1 TeV after future upgrade). The design of the ILC has entered the pre-project phase, which includes site-dependent design. Radiation safety design for the ILC is on-going as a part of conventional facility and siting activities of the pre-project phase. The thickness of a central wall of normal concrete is designed to be 3.5 m under a pessimistic assumption of beam loss. The beam loss scenario is under discussion. Experience and knowledge relating to shielding design and radiation control operational work at other laboratories are required. (authors)

    The objectives of this study are to determine the knowledge and attitude towards surgical safety among the health care professionals including surgeons, anaesthetist, hospital administrators, and operation room personnel and raise awareness towards the importance of safe surgery. Method: A pilot cross- sectional study of 543 healthcare providers working in the operating rooms and the surgical intensive care units was conducted in two tertiary care hospitals, within a study period of one month. A structured questionnaire was constructed and an informed verbal consent was taken. The questionnaire was then distributed; data collected and analysed on SPSS 20.0. Results: A total of 543 respondents participated in the study out of which there were 375 (69%) men and 168 (31%) women. The ages ranged between 23-58 years, mean 40.5+-24.74. There were 110 (20.25%) surgeons, 58 (10.68%) anaesthetist, 132 (24.30%) trainees, 125 (23.02%) technicians, and were 118 (21.73%) nurses. The question regarding briefing operation room personnel is important for patient safety was agreed by 532 (98%) respondents. Amongst the respondents, 239 (44%) did not feel safe to be operated in their own setup. Team communication improvement through the check list implementation was agreed by 483 (89%) respondents. 514 (94.7%) opted for the checklist to be used while they are being operated. That operation room personnel frequently disregard established protocols was agreed by 374 (69%) respondents. 193 (35.54%) of the respondents stated that it is difficult for them to speak up in the or if they perceive a problem with patient care. Conclusion: Operation room personnel were not aware of several important areas related to briefing, communication, safety attitude, following standard protocols and use of WHO Surgical Safety check list. A pre-post intervention study should be conducted after formal introduction of the Checklist. Successful implementation will require taking all stake holders on board

    Objective: To investigate the tendency of quality of life in patients with nasopharyngeal carcinoma (NPC) treated with conventional radiotherapy. Methods: Quality of life in NPC patients was assessed using FACT-H and N and NPC-QOL Patients were divided into nine groups according to the treatment period :before treatment group, 0 -20 Gy group, 20 -50 Gy group, > 50 Gy group, 0 -6 months after treatment group, 6 - 12 mouths group, 1 -2 years group, 2 -3 years group and 3 -5 years group. Scores of FACT-H and N and NPC-QOL were compared between the either two groups. Results: 450 NPC patients were assessed. The total score of FACT-H and N decreased during the treatment and then increased six months after the treatment. The tendencies of physical and functional well-being were similar. The social/family and emotional well-being did not change significantly along with the treatment but the scores of head and neck well-being and NPC-QOL decreased obviously. Xerotomia was aggravated from the initiation of treatment and became the most severe at 6 - 12 months after treatment. 50% - 60% of the patients with disease-free reported severe xerotomia at 3 -5 years after radiotherapy. Incidence of severe trismus increased up to 14% at 3 -5 years after treatment. Conclusions: Quality of life of NPC patients with conventional radiotherapy deteriorates during the treatment period, but recovers to the normal level six months after the treatment. Xerotomia and trismus can affect the quality of life of NPC patients. (authors)

    Objective: To compare the spine intensity modulated radiation therapy (IMRT) and the conventional radiation therapy on the beagle spinal cord neurons, in order to prove the biological safety of IMRT of the spinal cord. Methods: Twelve selected purebred beagles were randomly divided into 2 groups. A beagle clinical model of tumor was mimiced in the ninth and tenth thoracic vertebrae. Then the beagles were irradiated by 2 different models of intensity modulated radiotherapy and conventional radiation therapy, with the total irradiation doses of 50 and 70 Gy. The samples of spinal cord were taken out from the same position of the nine and tenth thoracic vertebrae at the third month after radiation.All the samples were observed by the electron microscope, and the Fas and HSP70 expression in spinal cord neurons were evaluated by immunohistochemistry method. Terminal deoxynucleatidyl transferase mediated dUTP nick and labeling (TUNEL) technique was used to examine the apoptotic cells in the spinal cord. Results: The neurons in the spinal cord of IMRT group were mainly reversible injury, and those in the conventional radiation therapy were mainly apoptosis. Compared with the conventional radiation therapy group [50 Gy group, (7.3 ± 1.1)%; 70 Gy group, (11.3 ± 1.4)%], the apoptosis rate of the spinal cord neurons of the intensity modulated radiotherapy group [50 Gy group, (1.2 ± 0.7)%; 70 Gy group (2.5 ± 0.8)%] was much lower[(50 Gy group, t=0.022, P<0.05; 70 Gy group, t=0.017, P<0.05)]. The expression levels of Fas in the IMPT group (50 Gy group, 4.6 ± 0.8; 70 Gy group, 7.4 ± 1.1) were also much lowerthan those in the other group (50 Gy group, 15.1 ± 6.4; 70 Gy group, 19.3 ± 7.6. 50 Gy group, t=0.231, P<0.05; 70 Gy group, t=0.457, P<0.05), while the expression levels of HSP70 in the IMPT group (50 Gy group, 9.1 ± 0.8; 70 Gy group, 7.3 ± 1.4)were much higher than those in the conventional radiation therapy group (50 Gy group, 2.1 ± 0.9; 70 Gy group, 1.7 ± 0

    2006-12-01

    The report represents the summary of the main factors, which affects the future development and state of the Baltic Sea. The emphasis is on land uplift, shoreline displacement, and physical, chemical and biological characteristics of the sea. In addition, historical evolution of the Baltic Sea after the last ice age and potential impacts of the different climate scenarios are presented. The Baltic Sea has an important influence on the development of the geospherebiosphere interface zone at Olkiluoto. Thus, it is important to take account all these factors in the Safety Modelling of the nuclear waste repository. Different models have been used to evaluate land uplift at Olkiluoto and changes in the sea and land area, especially in the interface zone. The main parameters have been monitored satisfactory way at the Olkiluoto offshore. Based on the present sea sediment stratigraphy, overburden, topography and vegetation it has been fairly well estimated coming future land and sea areas of the Olkiluoto Island and its surroundings. According to the results, Olkiluoto will be part of the continent during the next decade. In the shallow shores of Olkiluoto, the amounts of common reed are increasing naturally, resulting in paludification. The spatial and temporal changes at Olkiluoto can be estimated and modelled more detailed by using the well focused research sites and more accurate results. In addition, more information is needed on development of the watershed areas, lakes, rivers and vegetation and on sedimentation and erosion processes, hydrology, quality and quantity of seabed sediments and stratigraphy, element budgets and recharge and discharge areas, especially at the geosphere-biosphere interface zones.

    It is shown that the extended life and enhanced operational reliability of parts and subassemblies of the most popular GTK-10-4 gas transmission plants are determined by the enhanced efficiency of the control over technical condition and operational safety of turbine plants in conformity with industrial safety requirements imposed on gas pipeline compressor stations. It has been established that the materials of parts and subassemblies of gas turbine plants with different, especially with maximal operating time, shall be exposed to NDT for the purpose of determining the actual mechanical characteristics of these materials with different operating time and calculating residual life. The analysis of damageability and operating conditions has helped to identify parts and subassemblies for repair or replacement with the highest frequency of unacceptable defects. These parts and subassemblies have been shown to include base members of the axial compressor (AC), a turbine housing, an axial compressor rotor, high- and low-pressure turbine (HPT and LPT) discs, a 12-part holder, the housing of the holder of HPT and LPT guiding blades, a sealed baffler, and working and guiding AC, LPT and HPT blades. The most typical operational defects have been enumerated and analyzed. It has been determined that the primary task of the industrial safety appraisal for extending the life of GTK-10-4 with limit-exceeding operating time is to thoroughly examine HPT and LPT discs with more than 130,000 hours of operating time and establish by DT methods characteristics of materials for evaluation, taking account of their degradation, and residual life of critical turbine elements. In addition, it has been shown that the service life of HP turbine discs can be extended by replacing the disc material (EP-428 12% chromium steel) with a material with a higher linear expansion factor that somewhat exceeds the expansion factor of EI-893 nickel alloy used to melt out working blades.

    installation containing radioactive materials can be an 'installation classified on environmental protection grounds' (ICPEs) and is placed under the supervision of the Ministry for the Environment. In France there are about 600,000 industrial facilities in the ICPE category, including nearly 65,000 subject to issue of an authorization. If we consider only those ICPEs which are classified owing to the radioactive substances they contain or use, we obtain about 800 facilities. Facilities only containing small quantities of radioactive materials are not subject to regulatory supervision in this respect. The radioactive sources they use may nonetheless be subject to supervision, as mentioned in this report and remain subject to the general radiation protection regulations. For this second report, France took account of the experience acquired with its first report on the subject and on the three reports for the Convention on Nuclear Safety: this report is a stand-alone document based on existing documents and reflecting the viewpoints of the various stakeholders (regulatory authorities and operators). Thus, for each of the chapters in which the regulatory authority is not the only party to express its point of view, we adopted a three-stage structure: first of all a description by the regulatory authority of the regulations, followed by a presentation by the operators of the steps taken to meet the regulations and finally, an analysis by the regulatory authority of the steps taken by the operators. This report is structured according to the 'guidelines regarding national reports' for this Convention, in other words with an 'article by article' presentation. Each article is the subject of a separate chapter at the beginning of which the corresponding text of the Convention article is recalled in a shaded box. After this introduction (section A) the various sections deal with the following topics, in the order proposed in the 'guidelines': - section B: policy and practices in the

    International Nuclear Information System (INIS)

    2003-01-01

    This report is issued according to Article 32 of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management. Sweden signed the Joint Convention September 29, 1997 and the Joint Convention entered into force on June 18, 2001. The areas covered by the Joint Convention have been incorporated in the Swedish system for spent fuel and radioactive waste management for a long time. The Swedish Government considered at the time of signing of the Joint Convention that the safety philosophy, legislation and the safety work conducted by the licensees and the authorities in Sweden complied with the obligations of the Convention. This is confirmed in the present report. The Swedish Government directed the Swedish Nuclear Power Inspectorate (SKI) to prepare this report in co-operation with the Swedish Radiation Protection Authority (SSI). A working group of five persons, with representatives from SKI, SSI and the Swedish Nuclear Fuel and Waste Management Co. (SKB), has prepared this report. The report has been discussed in the boards of SKI and SSI. The Swedish Government adopted the report in April 2003. Section A of this report provides an overview of the Swedish nuclear waste programme, including a brief historical review, in order to give the reader a background to the current programme for the management of spent fuel and radioactive waste. Sections B to J provide information on which the conclusions are drawn about the compliance with the obligations of the Joint Convention. By necessity this information is rather brief and strongly focused on those aspects which are addressed in the articles. Too many details and additional information would over-load the report and make the review process difficult. The goal has been to provide enough details to make the Swedish practices understandable. Data that might be missing will be added on request as a part of the review process. Article 32 of the Joint Convention calls for a self

    In the aftermath of the Fukushima Daiichi accident in 2011, the Swiss government decided to phase out nuclear energy. Existing plants will continue to operate as long as they are considered safe by the Swiss Federal Nuclear Safety Inspectorate (ENSI) and as long as they fulfil all legal and regulatory requirements in this respect. In Switzerland, on-going activities regarding safety assessment of the different stages in the lifetime of nuclear installations consist of periodic assessments and assessments of long-term operation for existing Swiss nuclear power plants (NPPs). Assessments of long-term operation have been performed for two Swiss NPPs (Beznau and Muehleberg) which have been in commercial operation for over 40 years. A detailed examination demonstrated that the conditions for taking a NPP out of service have not yet been reached and will not be reached by these two plants within the next 10 years. Nevertheless, it is mandatory to continue with the scheduled ageing management, maintenance and backfitting activities. In late 2013, BKW Energy Ltd announced that Muehleberg NPP will be decommissioned at the end of 2019. The plant will shut down on December 20 th , 2019.The single 373 MWe boiling water reactor began operating in 1972. It will be the first Swiss nuclear power plant to be decommissioned. The preparatory work for decommissioning is well under way. In April 2015, a follow-up mission was conducted by the Integrated Regulatory Review Service in Switzerland. The Swiss government should give ENSI the ability to issue legally binding technical safety requirements and license conditions concerning nuclear safety, nuclear security and radiation safety. A follow-up mission by the Operational Safety Review Team on the Muehleberg NPP was completed in June 2014. Switzerland participated in the European Stress Test and its follow-up activities. During 2014, the necessary measures to achieve continuous improvement in the supervisory culture were defined. The

    Full Text: I am pleased to address this Second Extraordinary Meeting of the Contracting Parties to the Convention on Nuclear Safety. This important meeting will be closely watched by the global nuclear community. I know you will make good use of this opportunity to consider further measures to strengthen nuclear safety throughout the world in the light of the lessons which we are still learning from the Fukushima Daiichi accident. One year after the adoption of the IAEA Action Plan on Nuclear Safety, significant progress has been made in several key areas. These include the assessment of safety vulnerabilities of nuclear power plants, strengthening IAEA peer review services, improving emergency preparedness and response capabilities and reviewing IAEA safety standards. Your work this week will address the request to Contracting Parties, expressed in the Action Plan, to explore mechanisms to enhance the effective implementation of Safety Conventions and to consider proposals to amend the Convention on Nuclear Safety. You will recall that last year's Ministerial Declaration stressed 'the importance of universal adherence to, and the effective implementation and continuous review of, the relevant international instruments on nuclear safety'. The Action Plan encouraged Member States to work cooperatively to maximize the lessons learned from the Fukushima Daiichi accident and to produce concrete results as soon as possible. The IAEA has reported periodically to Member States about its work to implement the Action Plan. We have also organised a number of international expert meetings to analyse technical aspects of the accident and ensure that the right lessons are learned. The results of this Extraordinary Meeting will provide an important input to future considerations of implementation of the Action Plan. Our Member States will review implementation at the Agency's 56th General Conference next month, while the Fukushima Ministerial Conference on Nuclear Safety in

    Recent important experience in improving the operational safety and life of a reactor are described. The Kyoto University Reactor (KUR) is a 25-year-old 5 MW light water reactor provided with two thermal columns of graphite and heavy water as well as other kinds of experimental facilities. In the graphite thermal column, noticeable amounts of neutron irradiation effects had accumulated in the graphite blocks near the core. Before the possible release of the stored energy, all the graphite blocks in the column were successfully replaced with new blocks using the opportunity provided by the installation of a liquid deuterium cold neutron source in the column. At the same time, special seal mechanisms were provided for essential improvements to the problem of radioactive argon production in the column. In the heavy-water thermal column we have accomplished the successful repair of a slow leak of heavy water through a thin instrumentation tube failure. The repair work included the removal and reconstructions of the lead and graphite shielding layers and welding of the instrumentation tube under radiation fields. Several mechanical components in the reactor cooling system were also exchanged for new components with improved designs and materials. On-line data logging of almost all instrumentation signals is continuously performed with a high speed data analysis system to diagnose operational conditions of the reactor. Furthermore, through detailed investigations on critical components, operational safety during further extended reactor life will be supported by well scheduled maintenance programs

    Russian designers have developed and can deliver nuclear complexes to provide sea water desalination, industrial and district heating. This paper provides an overview of these designs utilizing the ABV, KLT-40 and ATETS-80 reactor plants of enhanced safety. The most advanced nuclear powered water desalination project is the APVS-80. This design consists of a special ship equipped with the distillation desalination plant powered at a level of 160 MW(th) utilizing the type KLT-40 reactor plant. More than 20 years of experience with water desalination and reactor plants has been achieved in Aktau and Russian nuclear ships without radioactive contamination of desalinated water. Design is also proceeding on a two structure complex consisting of a floating nuclear power station and a reverse osmosis desalination plant. This new technology for sea water desalination provides the opportunity to considerably reduce the specific consumption of power for the desalination of sea water. The ABV reactor is utilized in the ''Volnolom'' type floating nuclear power stations. This design also features a desalinator ship which provides sea water desalination by the reverse osmosis process. The ATETS-80 is a nuclear two-reactor cogeneration complex which incorporates the integral vessel-type PWR which can be used in the production of electricity, steam, hot and desalinated water.

  15. Mapping the knowledge base for maritime health: 4 safety and performance at sea.

    There is very little recent investigative work on the contribution of health related impairment and disability to either accident risks or to reduced performance at sea, the only exception being studies on fatigue and parallel data on sleep related incidents. Incidents where health related impairment, other than fatigue, has contributed are very rarely found in reports of maritime accident investigations. This may either indicate the irrelevance of these forms of impairment to accidents or alternatively point to the effectiveness of existing control measures. The main approach to risk reduction is by the application of fitness criteria to seafarers during medical examinations. Where there is a knowledge base it is either, as in the case of vision, a very old one that relates to patterns of visual task that differ markedly from those in modern shipping or, as with hearing, is based on untested assumptions about the levels of impairment that will prevent effective communications at sea. There are practical limitations to the assessment of cognitive functions as these encompass such a wide range of impairments from those associated with fatigue, medication, or substance abuse to those relating to age or to the risks of sudden incapacitation from a pre-existing illness. Physical capability can be assessed but only in limited ways in the course of a medical examination. In the absence of clear evidence of accident risks associated with health-related impairments or disabilities it is unlikely that there will be pressure to update criteria that appear to be providing satisfactory protection. As capability is related to the tasks performed, investigations need to integrate information on ergonomic and organizational aspects with that on health and impairment. Criteria that may select seafarers with health- -related impairment need to be reviewed wherever the task demands in modern shipping have changed, in order to relax or modify them where indicated in order to reduce

  20. Sweden's second national report under the Joint Convention on the safety of spent fuel management and on the safety of radioactive waste management. Swedish implementation of the obligations of the Joint Convention

    International Nuclear Information System (INIS)

    2005-01-01

    Article 32 of the Joint Convention calls for a self-assessment by each Contracting Party regarding compliance with the obligations of the Convention. Sweden's self-assessment has demonstrated compliance with all the obligations of the Convention, as shown in detail in sections B to K of this report. Having taken a very active part in the creation of the Joint Convention, Sweden wishes to emphasise the incentive character of the Convention. In Sweden's opinion, the Convention implies a commitment to continuous improvement of safety whenever operating experience, safety research or technical development indicates that there is room for such improvement. Continuous learning from experience and a proactive approach to safety are in fact corner stones of the current Swedish nuclear and radiation safety work, both for the industry and the regulatory bodies. Therefore, Sweden has found it important that its National Report highlights strong features in national practices, as well as areas in which improvements are justified. Implementation of such improvements should then be followed up in the National Reports to subsequent Review Meetings. The major events in the Swedish nuclear programme since the first report to the Convention was issued are: - The general safety regulations of SKI have been revised and issued as SKIFS 2004:1. - A commission of inquiry has been carried out in order to review and suggest improvements to the financing system. - The second unit of the twin nuclear power plant unit at Barsebaeck (Barsebaeck 2) was permanently shut down 31 May 2005. The first unit (Barsebaeck 1) was closed in 1999. - The research reactors R2 and R2-0 at the Studsvik site were permanently shut down 16 June 2005. - The Swedish Nuclear Fuel and Waste Management Co. (SKB) has announced its decision to take over operation of the interim storage facility for spent nuclear fuel (Clab). The operation of Clab is currently contracted out to OKG, who operates the three nuclear power

    Numerous studies have focused on off-pump coronary artery bypass graft (off-pump CABG) morbidity and mortality outcomes, but few looked at the patient's perception of the technique and its effect on postoperative quality of life (QOL). We investigated and compared postoperative QOL in patients who had undergone either conventional or off-pump CABG myocardial revascularization. During a six-month period, 191 patients who underwent CABG surgery were prospectively studied through preoperative and six-month postoperative short-form 36 (SF-36) general health status surveys. One hundred-sixteen (60.7%) off-pump CABG patients and 75 (39.3%) conventional on-pump CABG patients were enrolled. Sixteen (13.8%) off-pump patients reported improvement in physical score QOL, 84 (72.4%) reported no change, and 16 (13.8%) reported a decrease. In comparison, 20 (80.0%) patients in the on-pump CABG group reported an improvement in QOL, 42 (56.0%) were unchanged, and 13 (17.3%) reported deterioration (p = 0.28). For postoperative change in mental score, 19 (16.4%) off-pump patients reported an improvement, 85 (73.3%) stayed unchanged, and 12 (10.3%) reported a decrease compared with 8 (10.7%) conventional CABG patients reporting improvement, 60 (80.0%) showing no change, and 7 (9.3%), having a score decline (p = 0.52). In multivariate logistic regression analysis, hypertension (odds ratio [OR] 2.2, 95% confidence intervals [CI], 1.08 to 4.40, p = 0.03) and multivessel coronary artery disease (OR 2.1, 95% CI, 1.11 to 4.13, p = 0.02) emerged as independent predictors of worse physical score component score. Diabetes was associated with an improved physical score component score after CABG (OR 0.4, 95% CI, 0.17 to 0.76, p = 0.01), regardless of the surgical approach. This prospective study reveals no significant differences in the expected QOL at six months after either on-pump or off-pump CABG. Patients with hypertension and multivessel coronary artery disease were more likely to have

    Safety Culture covers all main directions of plant activities and the plant departments involved through integration into the INPP Quality Assurance System. Safety Culture is represented by three components. The first is the clear INPP Safety and Quality Assurance Policy. Based on the Policy INPP is safely operated and managers' actions firstly aim at safety assurance. The second component is based on personal responsibility for safety and attitude of each employee of the plant. The third component is based on commitment to safety and competence of managers and employees of the plant. This component links the first two to ensure efficient management of safety at the plant. The above mentioned components including the elements which may significantly affect Safety Culture are also presented in the attachment. The concept of such model implies understanding of effect of different factors on the level of Safety Culture in the organization. In order to continuously correct safety problems, self-assessment of the Safety Culture level is performed at regular intervals. (author)

    Construction is considered as one of the most hazardous activities owing to the number of accidents and injuries. At KKNPP, management of industrial safety has been envisaged since the preliminary stage of construction planning, including design aspects. The governing principles of safety management are evolved from the Factories Act, 1948, the Atomic Energy(Factories) Rules, 1996, AERB safety guidelines on Control of works (2011) and Corporate HSE policy of NPCIL (2014). Numerous risk assessment and hazard control measures are adopted consistently to ensure a safe work environment during the construction, which includes Job Hazard Analysis, work permit through Computerized Maintenance Management System, safety procedures, exclusive safety training facility for the contractor's workmen, safety motivational measures, safety surveillance and reporting through Safety Related Deficiencies Management System. Assessment of efficacy of safety management system is continuously done through safety audits and observations are being circulated and discussed in committee meetings. Fire safety is also being taken care of since inception of project work. Well-equipped fire station with trained fire fighters was made available since the beginning as per AERB safety standard on fire protection system for Nuclear facilities. Fire prevention measures specific to the work are implemented during all activities. (author)

    Spice extracts under the form of essential oils (Eos) were tested for their efficiency to increase the relative bacterial radiosensitivity (RBR) of Listeria monocytogenes, Escherichia coli and Salmonellatyphi in culture media under different atmospheric conditions. The selected Eos were tested for their ability to reduce the dose necessary to eliminate E. coli and S.typhi in medium fat ground beef (23% fat) and Listeria in ready-to-eat carrots when packed under air or under atmosphere rich in oxygen (MAP). Results have demonstrated that depending of the compound added and the combined treatment used, the RBR increased from 2 to 4 times. In order to evaluate the industrial feasibility, EOs were added in ground beef at a concentration which does not affect the taste and treated at a dose of 1.5 kGy. The content of total mesophilic aerobic, E. coli, Salmonella, total coliform, lactic acid bacteria, and Pseudomonas was determined during 28 days. The results showed that the combined treatment (radiation and EOs) can eliminate Salmonella and E. coli when done under air. When done under MAP, Pseudomonas could be eliminated and a shelf life of more than 28 days was observed. An active edible coating containing EOs was also developed and sprayed on ready-to-eat carrots before radiation treatment and Listeria was evaluated. A complete inhibition of Listeria was obtained at a dose of 0.5 kGy when applied under MAP. Our results have shown that the combination of an edible coating, MAP, and radiation can be used to maintain the safety of meat and vegetables.

    Metal impurities such as nickel and chrome are present in natural ingredients-containing cosmetic products. These traces are unavoidable due to the ubiquitous nature of these elements. Dead Sea mud is a popular natural ingredient of cosmetic products in which nickel and chrome residues are likely to occur. To analyze the potential systemic and local toxicity of Dead Sea mud taking into consideration Dead Sea muds' natural content of nickel and chrome. The following endpoints were evaluated: (Regulation No. 1223/20, 21/12/2009) systemic and (SCCS's Notes of Guidance) local toxicity of topical application of Dead Sea mud; health reports during the last five years of commercial marketing of Dead Sea mud. Following exposure to Dead Sea mud, MoS (margin of safety) calculations for nickel and chrome indicate no toxicological concern for systemic toxicity. Skin sensitization is also not to be expected by exposure of normal healthy skin to Dead Sea mud. Topical application, however, is not recommended for already nickel-or chrome-sensitized persons. As risk assessment of impurities present in cosmetics may be a difficult exercise, the case of Dead Sea mud is taken here as an example of a natural material that may contain traces of unavoidable metals.

    Extended half-life factor products have reduced annualized bleeding rates in hemophilia patients. The impact of extended half-life versus conventional factor products on hemophilia caregiver burden has not been investigated. This study aimed to evaluate caregiver burden in extended half-life versus conventional factor products for hemophilia A and B. This cross-sectional web-based study of caregivers of people with hemophilia A or B was recruited from a panel research company and by word of mouth. Participants completed the Hemophilia Caregiver Impact measure, the PedsQL Family Impact Module (PedsQL), and the Work Productivity and Activity Impairment Questionnaire (WPAI). We also collected demographic, insurance coverage, and medical information related to the hemophilia patient(s). Burden differences were assessed using linear regression and matched cohort analyses. The sample (n = 448) included 49 people who were caring for people on extended half-life factor products. Worse caregiver burden was associated with more infusions per week and more bleeds in the past 6 months. Regression analyses suggested that caring for someone who is on a extended half-life factor product is associated with lower emotional impact (β = - 0.11, p factor product had lower Emotional Impact and Practical Impact scores (t = - 2.95 and - 2.94, respectively, p factor product infusions of extended half-life factor products appears to reduce the emotional distress and practical burden of caregiving. Future work should evaluate the longitudinal impact.

Sporadic river-water analyses and regular measurements of pH, temperature, concentration of dissolved oxygen and conductivity, were performed in the water of the rivers Nant d'Avril (CH) and Le Lion (F) as well as in the water of the streams around the seven LHC sites PA2 − PA8. The concentrations of nitrogen oxides and ozone in the ambient air, which may be produced in accelerator facilities and released into the environment, were measured at two off-site monitoring stations in Maisonnex (CH) and Cessy (F)....

  19. A report on the environmental safety evaluation in sea disposal of radioactive wastes

    International Nuclear Information System (INIS)

    1976-01-01

    In October 1976, the Atomic Energy Commission of Japan decided its policy regarding radioactive wastes. It is stated that the sea disposal of low-level solid wastes as test will be made from about 1978, and after the confirmation of the safety, full-scale sea disposal will then follow. In this field, studies have long been made in Japan and international organizations. Based on these results, the present report describes on the following matters: the amount of radioactive wastes and the activities for disposal, the safety of disposal packages, the state of prospective sites for sea disposal, the models of the sea, the estimation of radionuclide concentrations in the ocean, and the exposure doses of general people.

This 5{sup th} report by the Swiss Federal Nuclear Safety Inspectorate (ENSI) provides an update on compliance with CNS obligations. The report attempts to give appropriate consideration to issues that aroused particular interest at the 4{sup th} Review Meeting. It starts with general political information on Switzerland, a brief history of nuclear power and an overview of Swiss nuclear facilities. This is followed by a comprehensive overview of the status of nuclear safety in Switzerland (as of July 2010) which indicates how Switzerland complies with the key obligations of the Convention. ENSI updated a substantial proportion of its guidelines which are harmonised with the safety requirements of the Western European Nuclear Regulators Association (WENRA) based on IAEA Safety Standards. On 1{sup st} January 2009, ENSI became formally independent of the Swiss Federal Office of Energy. It is now a stand-alone organisation controlled by its own management board. Switzerland recently started a process to select a site for the disposal of radioactive waste in deep geological formations. The first generation of NPPs in Switzerland has been the subject of progressive back-fitting. The second generation of NPPs incorporated various safety and operating improvements in their initial design. All Swiss NPPs have undergone the safety review process required under the Convention and have incorporated the improvements identified in the respective safety review reports. The Swiss policy of continuous improvements to NPPs ensures a high level of safety. The legislation and regulatory framework for nuclear installations is well established.

    Among currently identified issues presenting risks and benefits to human and ocean health, engineered nanoparticles (ENP) represent a priority. Predictions of their economic and social impact appear extraordinary, but their release in the environment at an uncontrollable rate is in striking contrast with the extremely limited number of studies on environmental impact, especially on the marine environment. The sea urchin has a remarkable sensing environmental system whose function and diversity came into focus during the recent years, after sea urchin genome sequencing. The complex immune system may be the basis wherefore sea urchins can adapt to a dynamic environment and survive even in hazardous conditions both in the adult and in the embryonic life. This review is aimed at discussing the literature in nanotoxicological/ecotoxicological studies with a focus on stress and innate immune signaling in sea urchins. In addition, here we introduce our current development of in vitro-driven probes that could be used to dissect ENP aftermaths, suggesting their future use in immune-nanotoxicology.

    Venom immunotherapy (VIT) is recommended as the first-line treatment for patients allergic to Hymenoptera venom. To analyze the safety and efficacy of VIT in a real life setting. One hundred and eighty patients undergoing VIT were studied to evaluate the safety, efficacy, incidence and nature of symptoms after field stings and adverse reactions to VIT. Significantly more patients were allergic to wasp than bee venom (146 vs. 34, p bees, and were not associated with angiotensin convertase inhibitors (ACEi) or β-adrenergic antagonists use. Systemic reactions were observed in 4 individuals on wasp VIT (2.7%) and in 6 patients allergic to bees (17.65%). The VIT was efficacious as most patients reported no reactions (50%) or reported only mild local reactions (43.75%) to field stings. The decrease in sIgE at completion of VIT correlated with the dose of vaccine received ( r = 0.53, p = 0.004). Beekeeping (RR = 29.54, p venom allergy. Venom immunotherapy is highly efficacious and safe as most of the adverse events during the induction and maintenance phase are mild and local. Side effects of VIT are more common in subjects on bee VIT. Beekeeping and female sex are associated with a higher risk of allergy to Hymenoptera venom.

    Full text: The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management, namely the Joint Convention, had been established in 1997. The objective of the Convention is to achieve and maintain a high level of safety worldwide in that fields to ensure that there are effective defenses against potential hazards so that individuals, society and the environment are protected from the harmful effects of ionizing radiation and to prevent accidents with radiological consequences and to mitigate their consequences. The Parties to the Convention intend to achieve this objective by international cooperation, peer reviews of each other's performance, assistance when needed for states with less developed programmes and capabilities and the use of internationally accepted standards of safety. The Joint Convention is rooted in the discussions held previously to the establishment of the Convention of the Nuclear Safety that had taken place in the period 1993-1994. The idea of a Convention on the Safety of waste management evolved since then, getting its final status in November 1997 after seven meetings of a specially appointed working group of outstanding specialists on the subject. After that, it was needed three years more until the number of the ratifying States, that then became Contracting Parties, to get the condition that let the Convention to enter into force: ninety days after the date of deposit with the Depository of the twenty-fifth instrument of ratification, acceptance or approval, including the instruments of fifteen States having an operational nuclear power plant. The First Review Meeting was held three years after it entered into force, in November 2003, with the attendance of 33 Parties that presented their National Reports. The second review meeting was held in May 2006. Forty-one Contracting Parties participated in the Second Review Meeting. There is then, a constant evolution in the number of Contracting Parties

  9. The safety of high activity long life nuclear waste

    1998-01-01

    The article concerns the deep geological storage for managing high activity long life nuclear waste. He puts forward a context giving a structure to the discussions of those involved concerning an assessment of the safety of a deep geological deposit project. Three main aspects are put forward. The risks for future generations and the time scales to be considered: briefly, the deposit needs to satisfy two functions for protecting man and the environment, namely firstly isolating high activity radionuclides from the biosphere during the time required for their radioactive decay (about ten thousands years), and secondly delay and dilute long life radionuclides without any a priori time limit so as to reduce their effects in the biosphere to extremely low levels. The risks are linked to possible failures of the containment barriers whose causes need to be analysed and be provided against by suitable provisions concerning their design. The definition of these design provisions requires an in depth examination of uncertain elements. The main causes of uncertainty are listed according to the scale of time in question, that is O-10,000 years, 10,000-100,000 years and beyond 100,000 years, stressing the importance of selecting a stable geological site and more generally a solid concept that is not very sensitive in uncertainties. Beyond 100,000 years the extent of uncertainties no longer makes it possible to make realistic predictions. It is thus necessary to consider the alternative scenarios concerning geological and climatic changes and the corresponding increasing risks of radionuclides. The risks in question may be relativized by realizing that on this time scale, the residual activities of soluble and insoluble alpha and beta emitters are comparable to those of a storage centre located on the surface at the end of the monitoring period. Finally, the article considers the approach put forward concerning the safety of a deep geological storage advocated by the French

  12. Total life-cycle cost analysis of conventional and alternative fueled vehicles

    1993-01-01

    Total Life-Cycle Cost (TLCC) Analysis can indicate whether paying higher capital costs for advanced technology with low operating and/or environmental costs is advantageous over paying lower capital costs for conventional technology with higher operating and/or environmental costs. While minimizing total life-cycle cost is an important consideration, the consumer often identifies non-cost-related benefits or drawbacks that make more expensive options appear more attractive. The consumer is also likely to heavily weigh initial capital costs while giving limited consideration to operating and/or societal costs, whereas policy-makers considering external costs, such as those resulting from environmental impacts, may reach significantly different conclusions about which technologies are most advantageous to society. This paper summarizes a TLCC model which was developed to facilitate consideration of the various factors involved in both individual and societal policy decision making. The model was developed as part of a US Department of Energy Contract and has been revised to reflect changes necessary to make the model more realistic. The model considers capital, operating, salvage, and environmental costs for cars, vans, and buses using conventional and alternative fuels. The model has been developed to operate on an IBM or compatible personal computer platform using the commercial spreadsheet program MicroSoft Excell reg-sign Version 4 for Windows reg-sign and can be easily kept current because its modular structure allows straightforward access to embedded data sets for review and update

  13. Reflexivity over and above convention: the new orthodoxy in the sociology of personal life, formerly sociology of the family.

    Science.gov (United States)

    Gilding, Michael

    2010-12-01

    There is a new orthodoxy in the field that was once understood as the sociology of the family, and is increasingly understood as the sociology of 'personal life', 'intimacy', 'relationships' and 'families'. The orthodoxy highlights the open-endedness of intimate relations at the expense of the family as an institution; that is, reflexivity over and above convention. This article argues that the new orthodoxy not only overstates reflexivity at the expense of convention, but abdicates understanding to frameworks grounded in biologistic and economistic understandings of human behaviour. The article makes its point through attention to three areas of research at odds with the new orthodoxy: paternity uncertainty, inheritance and family business. It then proposes that conceptualization of the family as an institutional regime gives due weight to the reflexive reconfiguration of family relationships and practices on the one hand, and their institutional embeddedness on the other.

In accordance with Article 5 of the Convention, Switzerland has prepared and submitted 4 country reports for Review Meetings of Contracting Parties organised in 1999, 2002, 2005 and 2006. These meetings at the IAEA headquarters in Vienna were attended by a Swiss delegation. Most of the requirements of the articles of the Convention were already standard practice in Switzerland. In the last years, all Swiss nuclear power plants (NPPs) as well as the Swiss Federal Nuclear Safety Inspectorate (HSK) built up documented quality management systems. The independence of HSK from licensing authorities is fulfilled on a technical level. In 2005, a new Nuclear Energy Act came into force requiring formal independence of the supervisory authorities from the licensing authorities.

    A new 3D seismic reflection data volume acquired in 2012 has allowed for the detailed mapping and characterization of gas hydrate distribution in the Pearl River Mouth Basin in the South China Sea. Previous studies of core and logging data showed that gas hydrate occurrence at high concentrations is controlled by the presence of relatively coarse-grained sediment and the upward migration of thermogenic gas from the deeper sediment section into the overlying gas hydrate stability zone (BGHSZ); however, the spatial distribution of the gas hydrate remains poorly defined. We used a constrained sparse spike inversion technique to generate acoustic-impedance images of the hydrate-bearing sedimentary section from the newly acquired 3D seismic data volume. High-amplitude reflections just above the bottom-simulating reflectors (BSRs) were interpreted to be associated with the accumulation of gas hydrate with elevated saturations. Enhanced seismic reflections below the BSRs were interpreted to indicate the presence of free gas. The base of the BGHSZ was established using the occurrence of BSRs. In areas absent of well-developed BSRs, the BGHSZ was calculated from a model using the inverted P-wave velocity and subsurface temperature data. Seismic attributes were also extracted along the BGHSZ that indicate variations reservoir properties and inferred hydrocarbon accumulations at each site. Gas hydrate saturations estimated from the inversion of acoustic impedance of conventional 3D seismic data, along with well-log-derived rock-physics models were also used to estimate gas hydrate saturations. Our analysis determined that the gas hydrate petroleum system varies significantly across the Pearl River Mouth Basin and that variability in sedimentary properties as a product of depositional processes and the upward migration of gas from deeper thermogenic sources control the distribution of gas hydrates in this basin.

  2. A new era of safety at CERN

    CERN is modernising its safety policy and organisational structure in matters of Safety with the introduction of new reference documents that have come into force on 29 September. These texts adapt the Organization’s safety policy to take account of how the Laboratory has evolved and to include best practice in Safety matters.   Safety is a priority at CERN, so it’s no coincidence that the Organization’s anniversary has been chosen as the time to launch a modernised approach to its Safety policy and how Safety matters are organised. On the day of CERN’s 60th anniversary, the SAPOCO 42 document, which covered both policy and organisational aspects, was replaced by a more concise general policy statement. The organisational structure and responsibilities in matters of Safety are now set out in a Safety Regulation, that is supplemented by subsidiary documents. Together these documents will replace the corresponding parts of the former SAPOCO 42 as well as Saf...

    Full Text Available The use of antibiotics in animal husbandry contributes to the worldwide problem of increasing antibiotic resistance in animal and human pathogens. Intensive animal production is considered an important source of antibiotic resistance genes released to the environment, while the contribution of smaller farms remains to be evaluated. Here we monitor the spread of tetracycline resistance (TC-r genes at a middle-size conventional dairy farm, where chlortetracycline (CTC, as intrauterine suppository is prophylactically used after each calving. Our study has shown that animals at the farm acquired the TC-r genes in their early age (1-2 weeks, likely due to colonization with TC-resistant bacteria from their mothers and/or the farm environment. The relative abundance of the TC-r genes tet(W, tet(Q and tet(M in fresh excrements of calves was about 1-2 orders of magnitude higher compared to heifers and dairy cows, possibly due to the presence of antibiotic residues in milk fed to calves. The occurrence and abundance of TC-r genes in fresh excrements of heifers and adult cows remained unaffected by intrauterine CTC applications, with tet(O, tet(Q and tet(W representing a ‘core TC-resistome’ of the farm, and tet(A, tet(M, tet(Y and tet(X occurring occasionally. The genes tet(A, tet(M, tet(Y and tet(X were shown to be respectively harbored by Shigella, Lactobacillus and Clostridium, Acinetobacter, and Wautersiella. Soil in the farm proximity, as well as field soil to which manure from the farm was applied, was contaminated with TC-r genes occurring in the farm, and some of the TC-r genes persisted in the field over 3 months following the manure application. Concluding, our study shows that antibiotic resistance genes may be a stable part of the intestinal metagenome of cattle even if antibiotics are not used for growth stimulation, and that smaller dairy farms may also contribute to environmental pollution with antibiotic resistance genes.

    Vitamin K plays important biological roles in maintaining normal blood coagulation, bone mineralization, soft tissue physiology, and neurological development. Menaquinone-7 is a form of vitamin K2 that occurs naturally in some animal-derived and fermented foods. It is also available as an ingredient of dietary supplements. Menaquinone-7 has greater bioavailability than other forms of vitamin K, which has led to increasing sales and use of menaquinone-7 supplements. This special article reviews the chemistry, nomenclature, dietary sources, intake levels, and pharmacokinetics of menaquinones, along with the nonclinical toxicity data available and the data on clinical outcomes related to safety (adverse events). In conclusion, the data reviewed indicate that menaquinone-7, when ingested as a dietary supplement, is not associated with any serious risk to health or with other public health concerns. On the basis of this conclusion, US Pharmacopeia monographs have been developed to establish quality standards for menaquinone-7 as a dietary ingredient and as a dietary supplement in various dosage forms. © The Author(s) 2017.

    2012-05-01

    On 11 March 2011 a massive earthquake of magnitude 9 followed by a devastating tsunami hit the east coast of Japan's main island Honshu. Those natural events triggered a series of malfunctioning and equipment failures that led to the severe nuclear accident at Fukushima Dai-ichi. The consequences of the accident have been dramatic for the Japanese population and the staff involved, and had a major impact on the public opinion as well. In Switzerland in particular the government and the parliament have decided to suspend the licensing process for the new builds and committed to a nuclear phase-out. In the global nuclear community the reaction to the accident has led to the adoption of the IAEA Action Plan by all member states. Within this framework, the Swiss Federal Nuclear Safety Inspectorate (ENSI) advocates an effective strengthening of the global nuclear safety regime, including mandatory international review missions and enhanced transparency in reporting. The European Union (EU) initiated a so-called stress test for its member countries with nuclear power plants in which also Switzerland participates. The EU stress tests is a focused reassessment of the European nuclear facilities on their protection against extreme external events (namely earthquakes, flooding and extreme weather conditions), against the loss of safety functions (namely in the case of prolonged station blackouts and loss of ultimate heat sink) and severe accident management in general. The reassessment aims at identifying safety margins beyond design and cliff edge effects. Beside the various international efforts which Switzerland actively supported, there has been a series of national actions taken by ENSI with the goal of understanding the event sequence in Fukushima and its causes so as to draw consequences for nuclear safety in Switzerland. In fact lessons have been identified, analyses performed and concrete measures adopted. In general terms the safety of the Swiss nuclear power

    Natural antimicrobials (NA) were tested for their efficiency at increasing bacterial relative radiosensitivity (BRR) and, therefore, reducing the radiation dose necessary to eliminate pathogens in meat and vegetables. In order to evaluate the industrial feasibility of using NA in combination to radiation to increase food shelf life, NA were added to food at low concentrations (which do not affect the sensory properties). Then, a bioactive coating formulation was developed to allow retention of the bioactivity of the NA during storage time. Results showed that NA, can increase BRR from 2 to 4 times and lower the dose necessary to eliminate a pathogen by a factor of 3 to 4. (author)

  10. Borders of life: lessons from Microbiology of deep-sea hydrothermal vents

    Science.gov (United States)

    Prieur, D.

    Thirty years ago, the deep-sea was known as a low density biotope due to coldness, darkness and famine-like conditions. The discovery of deep-sea hydrothermal vents in the Eastern Pacific in 1977 and the associated black smokers in 1979 considerably changed our views about life on Earth. For the first time, an ecosystem almost independent (at least for tens of years) of solar nergy was discovered. Besides the spectacular and unexpected communities of invertebrates based on symbiotic associations with chemo-litho-autotrophic bacteria, prokaryotic communities associated with high temperature black smokers fascinated microbiologists of extreme environments. Within mineral structures where temperature gradients may fluctuate from ambient seawater temperatures (2°C) up to 350°C, thermophilic (optimal growth above 60°C) and hyperthermophilic (optimal growth above 80°C) microorganisms thrived under very severe conditions due to elevated hydrostatic pressure, toxic compounds or strong ionizing radiations. These organisms belong to both domains of Bacteria and Archaea and live aerobically but mostly anaerobically, using a variety of inorganic and organic carbon sources, and a variety of electron donnors and acceptors as well. The most thermophilic organism known on Earth was isolated from a mid-Atlantic-Ridge hydrotermal vent: Pyrolobus fumarii grows optimally at 110°c and its upper temperature limit for life is 113°C. Such an organism survived to autoclaving conditions currently used for sterilization procedures. Many other hyperthermophilic organisms were isolated and described, including fermenters, sulphate and sulphur reducers, hydrogen oxidizers, nitrate reducers, methanogens, etc. Although most of anaerobes are killed when exposed to oxygen, several deep-sea hyperthermophiles appeared to survive to both oxygen and starvation exposures, indicating that they probably can colonize rather distant environments Because of elevated hydrostatic pressure that exists at

    2009-01-01

    The Joint Convention on the Safety of Spent Fuel Management and the Safety of Radioactive Waste Management, referred to as the 'Joint Convention', is the result of international discussions that followed the adoption of the Convention on Nuclear Safety, in 1994. France signed the Joint Convention at the General Conference of the International Atomic Energy Agency (IAEA) held on 29 September 1997, the very first day the Joint Convention was opened for signature. She approved it on 22 February 2000 and filed the corresponding instruments with the IAEA on 27 April 2000. The Joint Convention entered into force on 18 June 2001. For many years, France has been taking an active part in the pursuit of international actions to reinforce nuclear safety and considers the Joint Convention to be a key step in that direction. The fields covered by the Joint Convention have long been part of the French approach to nuclear safety. For his second report, France presented a document reflecting the viewpoints of the various stakeholders (regulatory authorities and operators). Thus, for each of the chapters in which the regulatory authority is not the only party to express its point of view, a three-stage structure was adopted: first of all a description by the regulatory authority of the regulations, followed by a presentation by the operators of the steps taken to meet the regulations and finally, an analysis by the regulatory authority of the steps taken by the operators. France received questions and comments from the other contracting parties of the joint convention and answered them in the present document

  13. Nautilus pompilius life history and demographics at the Osprey Reef Seamount, Coral Sea, Australia.

    Directory of Open Access Journals (Sweden)

    Andrew J Dunstan

    Full Text Available Nautiloids are the subject of speculation as to their threatened status arising from the impacts of targeted fishing for the ornamental shell market. Life history knowledge is essential to understand the susceptibility of this group to overfishing and to the instigation of management frameworks. This study provides a comprehensive insight into the life of Nautilus in the wild. At Osprey Reef from 1998-2008, trapping for Nautilus was conducted on 354 occasions, with 2460 individuals of one species, Nautilus pompilius, captured and 247 individuals recaptured. Baited remote underwater video systems (BRUVS were deployed on 15 occasions and six remotely operated vehicle (ROV dives from 100-800 m were conducted to record Nautilus presence and behavior. Maturity, sex and size data were recorded, while measurements of recaptured individuals allowed estimation of growth rates to maturity, and longevity beyond maturity. We found sexual dimorphism in size at maturity (males: 131.9±SD = 2.6 mm; females: 118.9±7.5 mm shell diameter in a population dominated by mature individuals (58%. Mean growth rates of 15 immature recaptured animals were 0.061±0.023 mm day(-1 resulting in an estimate of around 15.5 years to maturation. Recaptures of mature animals after five years provide evidence of a lifespan exceeding 20 years. Juvenile Nautilus pompilius feeding behavior was recorded for the first time within the same depth range (200-610 m as adults. Our results provide strong evidence of a K-selected life history for Nautilus from a detailed study of a 'closed' wild population. In conjunction with population size and density estimates established for the Osprey Reef Nautilus, this work allows calculations for sustainable catch and provides mechanisms to extrapolate these findings to other extant nautiloid populations (Nautilus and Allonautilus spp. throughout the Indo-Pacific.

    2002-01-01

    A powerful mechanism for increasing safety worldwide is through the development and adoption of legally binding Safety Conventions. Since 1986 four Conventions were ratified in the areas of Nuclear, Radiation and Waste Safety. The Nuclear Safety Convention establishes an international co-operation mechanism to maintain safety nuclear installations, focused on: to achieve and maintain a high level of nuclear safety worldwide through the enhancement of national measures and international co-operation including, where appropriate, safety-related technical co-operation; to establish and maintain effective defences in nuclear installations against potential radiological hazards in order to protect individuals, society and the environment from harmful effects of ionizing radiation from such installations and to prevent accidents with radiological consequences and to mitigate such consequences should they occur. Each contracting party shall take, within the framework of its national law, the legislative, regulatory and administrative measures and other steps necessary for implementing its obligations under this Convention. Moreover, each contracting parties shall submit for review prior to each review meeting, a National Report on the measures it has taken to implement each of the obligations of the Convention. The contracting parties concluded that the review process had proven to be of great value to their national nuclear safety programmes. (author)

    Lundteigen, Mary Ann; Rausand, Marvin; Utne, Ingrid Bouwer

    2009-01-01

    This article outlines a new approach to reliability, availability, maintainability, and safety (RAMS) engineering and management. The new approach covers all phases of the new product development process and is aimed at producers of complex products like safety instrumented systems (SIS). The article discusses main RAMS requirements to a SIS and presents these requirements in a holistic perspective. The approach is based on a new life cycle model for product development and integrates this model into the safety life cycle of IEC 61508. A high integrity pressure protection system (HIPPS) for an offshore oil and gas application is used to illustrate the approach.

    Two critical facilities, named STACY (Static Experiment Critical Facility) and TRACY (Transient Experiment Critical Facility), at the Nuclear Fuel Cycle Safety Engineering Research Facility (NUCEF) started their hot operations in 1995. Since then, basic experimental data for criticality safety research have been accumulated using STACY, and supercritical experiments for the study of criticality accident in a reprocessing plant have been performed using TRACY. In this paper, the outline of those critical facilities and the main results of TRACY experiments are presented. (author)

  18. Global mapping of nonseismic sea level oscillations at tsunami timescales.

    Vilibić, Ivica; Šepić, Jadranka

    2017-01-18

    Present investigations of sea level extremes are based on hourly data measured at coastal tide gauges. The use of hourly data restricts existing global and regional analyses to periods larger than 2 h. However, a number of processes occur at minute timescales, of which the most ruinous are tsunamis. Meteotsunamis, hazardous nonseismic waves that occur at tsunami timescales over limited regions, may also locally dominate sea level extremes. Here, we show that nonseismic sea level oscillations at tsunami timescales (sea level extremes, up to 50% in low-tidal basins. The intensity of these oscillations is zonally correlated with mid-tropospheric winds at the 99% significance level, with the variance doubling from the tropics and subtropics to the mid-latitudes. Specific atmospheric patterns are found during strong events at selected locations in the World Ocean, indicating a globally predominant generation mechanism. Our analysis suggests that these oscillations should be considered in sea level hazard assessment studies. Establishing a strong correlation between nonseismic sea level oscillations at tsunami timescales and atmospheric synoptic patterns would allow for forecasting of nonseismic sea level oscillations for operational use, as well as hindcasting and projection of their effects under past, present and future climates.

    Full text: Good afternoon, Dear Colleagues, Ladies and Gentlemen, I am pleased to say a few words to you at the end of the Sixth Review Meeting of the Contracting Parties to the Convention on Nuclear Safety. The Convention is a very important mechanism which has contributed a lot to strengthening nuclear safety in the countries which are party to it. In the last two weeks, you have addressed some very important issues. During your productive and lively discussions, a number of challenges were identified for consideration by Contracting Parties. These included: how to achieve harmonized emergency plans and response measures; how to make better use of operating and regulatory experience and international peer review services; and how to strengthen regulators' independence, safety culture, transparency and openness. The Agency will continue to work closely with you in addressing all of these issues. The Fifth Review Conference, which took place in 2011 just after the Fukushima Daiichi accident, was the first opportunity for Contracting Parties to address the accident in an international conference. The fact that you devoted a special session to the Fukushima Daiichi accident this time demonstrates the continued resolve of the Contracting Parties to ensure that the right lessons are learned everywhere. The Agency continues to work with all our Member States to implement the IAEA Action Plan on Nuclear Safety, about which you received a briefing. I know you will agree with me that it is vitally important that all the measures that have been agreed to strengthen global nuclear safety are actually implemented. Work continues on the IAEA report on the Fukushima Daiichi accident, which will be finalised this year. I understand that you decided to submit a proposal to amend the text of the Convention, addressing design and construction objectives for both existing and new nuclear power plants, to a Diplomatic Conference to be convened within one year. I am aware that a clear

    Concentrations of 23 per- and polyfluoroalkyl substances (PFASs), including new classes of PFASs, in seawater samples were investigated for their occurrence and the interaction of the ocean currents with the distribution of PFASs in the South China Sea. This study revealed that socio-economic development was associated with the PFAS contamination in coastal regions of South China. Significant correlations between concentration of total PFASs with gross domestic product (GDP) per capita and population density were found in the areas, suggesting that the influence of intense human activities in these areas may have resulted in higher PFAS contamination to the adjacent environment. Di-substituted polyfluoroalkyl phosphate (diPAP), one of the potential replacements for PFASs, was only detected in the heavily developed region, namely Pearl River Delta (PRD). Total PFAS concentrations, ranging from 195 to 4925 pg/L, were detected at 51 sampling stations of the South China Sea. The results also confirmed that PFAS contamination in the South China Sea is strongly affected by the ocean currents. In comparison to perfluoroactane sulfonate (PFOS) concentrations measured nine years ago at the same locations, the concentrations in this study were found to be two times higher. This indicated that the use and production of perfluoroalkyl sulfonates (PFSAs) has been continuing in the region. Copyright © 2014 Elsevier B.V. All rights reserved.

    Zaki, S.; Sekimoto, H.

    1995-01-01

    Safety aspects of several design options of long-life small safe fast power reactors using nitride fuel and lead-bismuth as coolant are discussed. In the present study hypothetical accidents are simulated for these reactors, i.e., unprotected simultaneous ULOF (total loss of primary pumping system) and UTOP (rod run out transient over power) accidents, caused by the simultaneous withdrawal of all control rods. The proposed designs have some important safety characteristics as low reactivity swing (only 0.2-0.25$), and negative coolant void coefficient over whole burnup period. Effectively negative value of all components of reactivity during an accident is observed. The safety performances of the balance, pancake, and tall slender type of core, each of them satisfy reactivity and negative coolant void coefficient constraint, against the above accident are compared. The simulation results show that all of the design options can survive the above accidents without the help of reactor scram and without the need of operator actions. (author)

    We sought to compare robotic vs laparoscopic surgery in regards to patient reported postoperative pain and quality of life. This was a prospective study of patients who presented for treatment of a new gynecologic disease requiring minimally invasive surgical intervention. All subjects were asked to take the validated Brief Pain Inventory-Short Form at 3 time points to assess pain and its effect on quality of life. Statistical analyses were performed using Pearson x(2) and Student's t test. One hundred eleven were included in the analysis of which 56 patients underwent robotic assisted surgery and 55 patients underwent laparoscopic surgery. There was no difference in postoperative pain between conventional laparoscopy and robotic assisted surgery for gynecologic procedures. There was a statistically significant difference found at the delayed postoperative period when evaluating interference of sleep, favoring laparoscopy (ROB 2.0 vs LSC 1.0; P = .03). There were no differences found between the robotic and laparoscopic groups of patients receiving narcotics (56 vs 53, P = .24, respectively), route of administration of narcotics (47 vs 45, P > .99, respectively), or administration of nonsteroidal antiinflammatory medications (27 vs 21, P = .33, respectively). Our results demonstrate no difference in postoperative pain between conventional laparoscopy and robotic assisted surgery for gynecologic procedures. Furthermore, pain did not appear to interfere consistently with any daily activity of living. Interference of sleep needs to be further evaluated after controlling for bilateral salpingo-oophorectomy. Copyright © 2015 Elsevier Inc. All rights reserved.

    2006-01-01

    This paper describes the relationship between the overall safety life cycle and the software safety life cycle during the development of the software based safety systems of Nuclear Power Plants. This includes the design and evaluation activities of components as well as the system. The paper also compares the safety life cycle and planning activities defined in IEC 61508 with those in IEC 60880, IEEE 7-4.3.2, and IEEE 1228. Using the KNICS project as an example, software safety life cycle and safety analysis methods applied to the POSAFE-Q are demonstrated. KNICS software safety life cycle is described by comparing to the software development, testing, and safety analysis process with international standards. The safety assessment of the software for POSAFE-Q is a joint Korean German project. The assessment methods applied in the project and the experiences gained from this project are presented

    2001-01-01

    The present document is the second Spanish national report prepared in order to comply with the obligations deriving from the convention on Nuclear Safety, made in Vienna on 20th September 1994. This convention was signed by Spain on 15th October 1994 and ratified by way of an instrument issued by the Ministry of Foreign Affairs, signed by H. M. the King on 19th June 1995. The convention, which entered into force on 24th October 1996, following ratification by a minimum number of countries, as set out in articles 20, 21 and 22 includes 51 countries and Euratom, in addition to Spain. The first review meeting, organised in accordance with chapter 3 of the Convention, was held in vienna in April 1999. Spain was represented by the CSN, the State organisation solely responsible for nuclear safety, both for the drawing up of the national report and for participation in the meeting held between the parties. In accordance with article 21, the second review meeting has been scheduled for April 2002, also in Vienna. At the review meeting, the countries party to the Convention review the national reports required by article 5, Spain submitted its first national report in September 1998. The present document is an update of that first report, and is to be submitted by 15th October 2001, as agreed on during the first review meeting. This report will be reviewed by the interested countries, which will forward their comments and questions. In April 2002, the Spanish report and the questions received will be subjected to the review process contemplated by the convention, along with the reports submitted by the other countries

  9. A proposal for an international convention on radiation safety

    International Nuclear Information System (INIS)

    Ahmed, J.U.

    1998-01-01

    One century has passed since harmful effects of radiation on living tissues were recognized. Organized efforts to reduce radiation hazards began in early 1920s. Major efforts by the ICRP since 1928, aided by ICRU, greatly helped in formulating principles, policies and guidance for radiation protection. The WHO formally recognized ICRP in 1956 and began implementing ICRP recommendations and guidance throughout the world. The IAEA, after it took office in 1957, began to establish or adopt standards of safety based on ICRP recommendations and provide for application of these standards in the field of atomic energy. Later on, other pertinent international organizations joined IAEA in establishing the Basic Safety Standards on radiation safety. The IAEA has issued, until now, nearly couple of hundred safety related documents on radiation safety and waste management. However, in spite of all such international efforts for three quarter of a century, there has been no effective universal control in radiation safety. Problems exist at the user, national, international and manufacturers and suppliers levels. Other problems are management of spent sources and smuggling of sources across international borders. Although, radiation and radionuclides are used by all countries of the world, regulatory and technical control measures in many countries are either lacking or inadequate. The recommendations and technical guidance provided by the international organizations are only advisory and carry no mandatory force to oblige countries to apply them. Member States approve IAEA safety standards and guides at the technical meetings and General Conference, but many of them do not apply these. An International Convention is, therefore, essential to establish international instrument to ensure universal application of radiation safety. (author)

    Minimally processed fruits and vegetables are one of the major growing sectors in food industry. This growing demand for healthy and convenient foods with fresh-like properties is accompanied by concerns surrounding efficacy of the available sanitizing methods to appropriately deal with food-borne diseases. In fact, chemical sanitizers do not provide an efficient microbial reduction, besides being perceived negatively by the consumers, dangerous for human health, and harmful to the environment, and the conventional thermal treatments may negatively affect physical, nutritional, or bioactive properties of these perishable foods. For these reasons, the industry is investigating alternative nonthermal physical technologies, namely innovative packaging systems, ionizing and ultraviolet radiation, pulsed light, high-power ultrasound, cold plasma, high hydrostatic pressure, and dense phase carbon dioxide, as well as possible combinations between them or with other preservation factors (hurdles). This review discusses the potential of these novel or emerging technologies for decontamination and shelf-life extension of fresh and minimally processed fruits and vegetables. Advantages, limitations, and challenges related to its use in this sector are also highlighted.

    Full Text Available A common sustainability issue, arising in production systems, is the efficient use of resources for providing goods or services. With the increased interest in a hydrogen (H2 economy, the life-cycle environmental performance of H2 production has special significance for assisting in identifying opportunities to improve environmental performance and to guide challenging decisions and select between technology paths. Life cycle impact assessment methods are rapidly evolving to analyze multiple environmental impacts of the production of products or processes. This study marks the first step in developing process-based streamlined life cycle analysis (LCA of several H2 production pathways combining life cycle impacts at the midpoint (17 problem-oriented and endpoint (3 damage-oriented levels using the state-of-the-art impact assessment method ReCiPe 2016. Steam reforming of natural gas, coal gasification, water electrolysis via proton exchange membrane fuel cell (PEM, solid oxide electrolyzer cell (SOEC, biomass gasification and reforming, and dark fermentation of lignocellulosic biomass were analyzed. An innovative aspect is developed in this study is an analysis of water consumption associated with H2 production pathways by life-cycle stage to provide a better understanding of the life cycle water-related impacts on human health and natural environment. For water-related scope, Water scarcity footprint (WSF quantified using Available WAter REmaining (AWARE method was applied as a stand-alone indicator. The paper discusses the strengths and weaknesses of each production pathway, identify the drivers of environmental impact, quantify midpoint environmental impact and its influence on the endpoint environmental performance. The findings of this study could serve as a useful theoretical reference and practical basis to decision-makers of potential environmental impacts of H2 production systems.

    The utilization at the coastal areas of Black Sea basin has increased in the recent years with the projects such as large commercial ports, international transportation hubs, gas and petrol pipelines, touristic and recreational infrastructures both along surrounding shoreline. Although Black Sea is a closed basin, extreme storms and storm surges have also been observed with an increasing frequency in the recent years. Among those events, February 1999, March 2013 and September 2014 storms impacted Southern coast of Black sea have clearly shown that the increasing economic value at the coastal areas caused the increasing cost of damages and loss of property by natural hazards. The storm occurred on February 19-20, 1999 is one of the most destructive storm in the last decades. The 1999 event (1999 Southern Black sea storm) caused destruction at all harbors and coastal protection structures along the Black Sea coast of Turkey. The complete damage of the breakwater of Giresun Harbor and damage on the harbor structures and cargo handling equipment were the major impacts of the 1999 Southern Black sea storm. Similar coastal impact have also been observed during the September 24, 2014 storm at 500m East of Giresun harbor. Although there are considerable number of destructive storms observed at southern coast of Black sea recently, data on these events are limited and vastly scattered. In this study the list of recent extreme marine events at South coast of the Black sea compiled and related data such as wind speed, wave height, period, and type of damages are cataloged. Particular attention is focused on the 1999 and 2014 storm events. The meteorological and morphological characteristics which may be considered as the reasons of the generation and coastal amplification of these storms are discussed.

    Handling of digestate produced by anaerobic digestion impacts the environment through emission of greenhouse gases, reactive nitrogen, and phosphorus. Previous life cycle assessments (LCA) evaluating the extraction of nutrients from digestate using struvite precipitation and ammonia stripping did not relate synthetic fertilizer substitution (SFS) to nutrient use efficiency consequences. We applied an expanded LCA to compare the conventional management of 1 m 3 of liquid digestate (LD) from food waste against the production and use of digestate biofertilizer (DBF) extracted from LD, accounting for SFS efficacy. Avoidance of CH 4 , N 2 O, and NH 3 emissions from LD handling and enhanced SFS via more targeted use of nutrients in the versatile DBF product could generate environmental savings of up to 0.129 kg Sb eq, 4.16 kg SO 2 eq, 1.22 kg PO 4 eq, 33 kg CO 2 eq, and 20.6 MJ eq per m 3 LD, for abiotic resource depletion, acidification, eutrophication, global warming, and cumulative energy demand burdens, respectively. However, under worst-case assumptions, DBF extraction could increase global warming and cumulative energy demand by 7.5 kg CO 2 e and 251 MJ eq per m 3 LD owing to processing inputs. Normalizing these results against per capita environmental loadings, we conclude that DBF extraction is environmentally beneficial.

    2006-01-01

    Pakistan is benefiting from nuclear technology mostly in health and energy sectors as well as agriculture and industry and has an impeccable safety record. At the national level uses of nuclear technology started in 1955 resulting in the operation of Karachi Radioisotope Center, Karachi, in December 1960. Pakistan Nuclear Safety Committee (PNSC) was formulated in 1964 with subsequent promulgation of Pakistan Atomic Energy Commission (PAEC) Ordinance in 1965 to cope with the anticipated introduction of a research reactor, namely PARR-I, and a nuclear power plant, namely KANUPP. Since then Pakistan's nuclear program has expanded to include numerous nuclear facilities of varied nature. This program has definite economic and social impacts by producing electricity, treating and diagnosing cancer patients, and introducing better crop varieties. Appropriate radiation protection includes a number of measures including database of sealed radiation sources at PAEC operated nuclear facilities, see Table l, updated during periodic physical verification of these sources, strict adherence to the BSS-115, IAEA recommended enforcement of zoning at research reactors and NPPs, etc. Pakistan is party to several international conventions and treaties, such as Convention of Nuclear Safety and Early Notification, to improve and enhance safety at its nuclear facilities. In addition Pakistan generally and PAEC particularly believes in a blend of prudent regulations and good/best practices. This is described in this paper. (Author)

    Electric drive vehicle technologies are being considered as possible solutions to mitigate environmental problems and fossil fuels dependence. Several studies have used life cycle analysis technique, to assess energy use and CO 2 emissions, addressing fuels Well-to-Wheel life cycle or vehicle's materials Cradle-to-Grave. However, none has considered the required infrastructures for fuel supply. This study presents a methodology to evaluate energy use and CO 2 emissions from construction, maintenance and decommissioning of support infrastructures for electricity and fossil fuel supply of vehicles applied to Portugal case study. Using Global Warming Potential and Cumulative Energy Demand, three light-duty vehicle technologies were considered: Gasoline, Diesel and Electric. For fossil fuels, the extraction well, platform, refinery and refuelling stations were considered. For the Electric Vehicle, the Portuguese 2010 electric mix, grid and the foreseen charging point's network were studied. Obtained values were 0.6–1.5 gCO 2eq /km and 0.03–0.07 MJ eq /km for gasoline, 0.6–1.6 gCO 2eq /km and 0.02–0.06 MJ eq /km for diesel, 3.7–8.5 gCO 2eq /km and 0.06–0.17 MJ eq /km for EV. Monte Carlo technique was used for uncertainty analysis. We concluded that EV supply infrastructures are more carbon and energetic intensive. Contribution in overall vehicle LCA does not exceed 8%. - Highlights: ► ISO 14040 was applied to evaluate fuel supply infrastructures of ICE and EV. ► CED and GWP are used to assess the impact on WTW and CTG stages. ► EV chargers rate and ICE stations' lifetime influence uncertainty the most. ► EV facilities are more carbon and energetic intense than conventional fuels. ► Contribution of infrastructures in overall vehicle LCA does not exceed 8%.

    Full Text Available Background: Over the past 30 years, pretransfusion tests have undergone considerable modification. In 1984, AABB recommended that the full cross match could be replaced by an abbreviated cross match in patients with negative antibody screen. However, before implementation of such a policy, issue regarding safety of T & S needs to be evaluated. Objectives: The aim of pretransfusion testing (PTT is to ensure that enough red blood cells (RBCs in the selected red cell components will survive when transfused. Results and Conclusion: We have, therefore in this study; evaluated safety of T & S procedure for PTT in comparison with conventional test tube cross match. The T & S procedure gave a safety of 91.6%. Also, the usefulness of the T & S was shown through the detection of unexpected antibodies in 0.75% (15 out of 2026 of cases.

    The study aimed at exploring the safety of various fresh fruit juices, blends and drinks sold in the streets of Multan, Pakistan. The city was divided into 4 zones for the purpose of sample collection. Bacteriological analysis of 72 samples of fresh fruit juices, blends and drinks indicated the presence of total viable counts (2.48 +- 0.16 to 7.91 +- 0.62 log CFU/mL), total coliforms (0.70 +- 0.04 to 4.86 +- 0.29 log CFU/mL) and Escherichia coli (0.6 +- 0.03 to 3.83 +- 0.32 log CFU/mL). Qualitative data depicted apple juice to be highly contaminated with fecal coliforms and Salmonella spp. Coliforms prevalence was highest in Zone IV and Zone II while that of Salmonella spp., in Zone IV and Zone III. The pragmatic levels of contaminants elucidate poor sanitary status of major entities deployed in juice manufacturing process adopted by the street vendors. (author)

    2006-01-01

    Purpose: Head-and-neck radiotherapy is associated with significant morbidities. Our purpose was to document impact of morbidities by use of multiple objective measures and health-related quality of life (HR-QOL). Methods and Materials: Ten head-and-neck cancer patients were evaluated before receiving conventional head-and-neck radiotherapy and at 1 month and 6 months after treatment. We evaluated weight, saliva production, diet, swallow function, auditory function, and HR-QOL. Results: After radiotherapy, weight was reduced in 89% of subjects. Salivary function was significantly reduced and did not resolve by 6 months. Diet impairment and abnormalities in swallowing function persisted at 6 months. Perception of physical functioning was reduced after treatment, and swallowing, coughing, and dry-mouth symptoms increased. Very few changes were observed in auditory function. Conclusions: Conventional head-and-neck radiotherapy is associated with substantial functional deficits and diminished HR-QOL. Deficits reported here can serve as a baseline for comparison with results derived from new radiotherapy-treatment techniques

    Vieno, T.; Ikonen, A.T.K.

    2005-02-01

    Posiva aims to present the Safety Case supporting the construction license application of the spent fuel repository at Olkiluoto by 2012. An outline and preliminary assessments will be presented in 2009. Interim reporting and an update of the Safety Case plan will be presented in 2006, as required by the authorities. The KBS-3 disposal concept aims at long-term isolation and containment of spent fuel assemblies in durable copper-iron canisters emplaced in a repository to be constructed at a depth between 400 and 600 metres in crystalline bedrock. By 2012, studies on the KBS-3 disposal concept and site investigations at Olkiluoto will have been continued over about thirty years. The construction of an underground rock characterisation facility (called ONKALO) was started in June 2004. The investigations are carried out in close cooperation with the Swedish SKB developing and assessing the same disposal concept at candidate sites, resembling Olkiluoto, at the other side of the Baltic Sea. A safety case is the synthesis of evidence, analyses and arguments that quantify and substantiate the safety, and the level of expert confidence in the safety, of a planned repository. Posiva's Safety Case will be organised in a portfolio including ten main reports, which will be periodically updated according the overall schedule presented in the plan. The Site report describing the present state and past evolution of the Olkiluoto site, as well as the disturbances caused by the construction of ONKALO and the first stage of the repository, forms the geoscientific basis of the Safety Case. The engineering basis is provided by the reports on the Characteristics of spent fuel, Canister design, and Repository design. The Process report containing descriptions and analyses of features, events and processes potentially affecting the disposal system, and the report on the Evolution of site and repository form the scientific basis of the Safety Case. The latter report will describe and

    The underlying mechanisms of altitude training are still a matter of controversial discussion but erythropoietic adaptations with an increase of total haemoglobin mass (tHb) have been shown in several studies, partly depending on an adequate hypoxic dose. The aim of this retrospective study was to investigate if a 3 weeks sojourn at moderate altitude (1816 m) with conventional training sessions (live and train at moderate altitude), especially under real and uncontrolled conditions, results in an increased tHb. tHb was measured in seven male cyclists competing at elite level (German national cycling team, U23 category) prior to the ascent to altitude and immediately after descent to sea-level. The athletes completed a 21 days altitude training camp living at 1816 m and training at 1800-2400 m during the competitive season. No significant difference was found in tHb after the altitude sojourn (prior 927+/-109g vs. 951+/-113g post, 95% CI -13-61g). Additionally, the analysis of red cell volume, plasma volume and blood volume or haemoglobin concentration [Hb] as well as haematocrit (Hct) did not reveal any significant changes. The data supports the theory that an adequate hypoxic dose is required for adaptations of the erythropoietic system with an increase of tHb and a threshold of approximately 2100-2500 m has to be exceeded.

  9. Proteomic profiles reveal age-related changes in coelomic fluid of sea urchin species with different life spans.

    Science.gov (United States)

    Bodnar, Andrea

    2013-05-01

    Sea urchins have a different life history from humans and traditional model organisms used to study the process of aging. Sea urchins grow indeterminately, reproduce throughout their life span and some species have been shown to exhibit negligible senescence with no increase in mortality rate at advanced ages. Despite these properties, different species of sea urchins are reported to have very different natural life spans providing a unique model to investigate cellular mechanisms underlying life span determination and negligible senescence. To gain insight into the biological changes that accompany aging in these animals, proteomic profiles were examined in coelomic fluid from young and old sea urchins of three species with different life spans: short-lived Lytechinus variegatus, long-lived Strongylocentrotus franciscanus and Strongylocentrotus purpuratus which has an intermediate life span. The proteomic profiles of cell-free coelomic fluid were complex with many proteins exhibiting different forms and extensive post-translational modifications. Approximately 20% of the protein spots on 2-D gels showed more than two-fold change with age in each of the species. Changes that are consistent with age in all three species may prove to be useful biomarkers for age-determination for these commercially fished marine invertebrates and also may provide clues to mechanisms of negligible senescence. Among the proteins that change with age, the ectodomain of low-density lipoprotein receptor-related protein 4 (LRP4) was significantly increased in the coelomic fluid of all three sea urchin species suggesting that the Wnt signaling pathway should be further investigated for its role in negligible senescence.

  10. Probabilistic Safety Analysis of High Speed and Conventional Lines Using Bayesian Networks

    Energy Technology Data Exchange (ETDEWEB)

    Grande Andrade, Z.; Castillo Ron, E.; O' Connor, A.; Nogal, M.

    2016-07-01

    A Bayesian network approach is presented for probabilistic safety analysis (PSA) of railway lines. The idea consists of identifying and reproducing all the elements that the train encounters when circulating along a railway line, such as light and speed limit signals, tunnel or viaduct entries or exits, cuttings and embankments, acoustic sounds received in the cabin, curves, switches, etc. In addition, since the human error is very relevant for safety evaluation, the automatic train protection (ATP) systems and the driver behavior and its time evolution are modelled and taken into account to determine the probabilities of human errors. The nodes of the Bayesian network, their links and the associated probability tables are automatically constructed based on the line data that need to be carefully given. The conditional probability tables are reproduced by closed formulas, which facilitate the modelling and the sensitivity analysis. A sorted list of the most dangerous elements in the line is obtained, which permits making decisions about the line safety and programming maintenance operations in order to optimize them and reduce the maintenance costs substantially. The proposed methodology is illustrated by its application to several cases that include real lines such as the Palencia-Santander and the Dublin-Belfast lines. (Author)

    2001-10-01

    The document represents a specific type of discussion of existing methodologies for the creation and application of probabilistic safety assessment (PSA) in light of the EUR document summarizing requirements placed by Western European NPP operators on the future design of nuclear power plants. A partial goal of this discussion consists in mapping, from the PSA point of view, those selected design, operational and/or safety factors of future NPPs that may be entirely new or, at least, newly addressed. Therefore, the terms of reference for this stage were formulated as follows: Assess current level of knowledge and procedures in the analysis of factors and phenomena with a dominant influence upon operational safety of new generation reactors, especially in the following areas: (1) Phenomenology of failure types and mechanisms and reliability of conventional passive safety system components; (2) Phenomenology of failure types and mechanisms and reliability of non-conventional passive components of newly designed safety systems; (3) Phenomenology of types and mechanisms of dependent failures; (4) Human factor role in new generation reactors and its effect upon safety; (5) Fire safety and other external threats to new nuclear installations; (6) Reliability of the digital systems of the I and C system and their effect upon safety; and (7) Organizational factors in new nuclear installations.

  14. 3. French national report on implementation of the obligations of the Convention on nuclear safety - Issued for the 2005 Peer review meeting

    International Nuclear Information System (INIS)

    2004-01-01

    Conduct on the safety of research reactors, which incorporates most of the provisions of the present Convention. This report was produced by the Nuclear Safety Authority (ASN), which ensured the necessary coordination, together with the Institute for Radiation Protection and Nuclear Safety (IRSN) as well as the nuclear power reactor operators, Electricite de France (EDF), the Atomic Energy Commission (CEA) and the Laue - Langevin Institute (ILL). The final version was completed in July 2004 after consultation with the French parties concerned. For this report, France took account of the experience acquired with its first two reports: this report is a stand-alone document based mainly on existing documents and reflecting the viewpoints of the various stakeholders (Regulatory authority and operators). Thus, for each of the chapters in which the regulatory authority is not the only party to express its point of view, we adopted a three-stage structure: first of all a description by the regulatory body of the regulations, followed by a presentation by the operators of the steps taken to meet the regulations and finally, an analysis by the regulator of the steps taken by the operators. The report is structured according to the guidelines for national reports, as modified during the 2002 peer review meeting. The presentation is made 'Article by Article', each being the subject of a different chapter, at the beginning of which the corresponding text of the Convention is repeated in a shadow box. The current introduction highlights the main changes since the second national report together with France's nuclear energy policy. Part A deals with the general provisions (Articles 4 to 6). Part B summarizes the legislation and regulations (Articles 7 to 9). Part C is devoted to general safety considerations (Articles 10 to 16). Part D discusses the safety of the installations (Articles 17 to 19). Finally, the conclusion gives indications on future trends in the field of nuclear safety

    Many current organic arable agriculture systems are challenged by a dependency on imported livestock manure from conventional agriculture. At the same time organic agriculture aims at being climate friendly. A life cycle assessment is used in this paper to compare the carbon footprints of different....... The results showed significantly lower carbon footprint of the crops from the ‘Biogas’ rotation (assuming that biogas replaces fossil gas) whereas the remaining crop rotations had comparable carbon footprints per kg cash crop. The study showed considerable contributions caused by the green manure crop (grass......-clover) and highlights the importance of analysing the whole crop rotation and including soil carbon changes when estimating carbon footprints of organic crops especially where green manure crops are included....

  18. Steady as he goes: at-sea movement of adult male Australian sea lions in a dynamic marine environment.

    Directory of Open Access Journals (Sweden)

    Andrew D Lowther

    Full Text Available The southern coastline of Australia forms part of the worlds' only northern boundary current system. The Bonney Upwelling occurs every austral summer along the south-eastern South Australian coastline, a region that hosts over 80% of the worlds population of an endangered endemic otariid, the Australian sea lion. We present the first data on the movement characteristics and foraging behaviour of adult male Australian sea lions across their South Australian range. Synthesizing telemetric, oceanographic and isotopic datasets collected from seven individuals enabled us to characterise individual foraging behaviour over an approximate two year time period. Data suggested seasonal variability in stable carbon and nitrogen isotopes that could not be otherwise explained by changes in animal movement patterns. Similarly, animals did not change their foraging patterns despite fine-scale spatial and temporal variability of the upwelling event. Individual males tended to return to the same colony at which they were tagged and utilized the same at-sea regions for foraging irrespective of oceanographic conditions or time of year. Our study contrasts current general assumptions that male otariid life history strategies should result in greater dispersal, with adult male Australian sea lions displaying central place foraging behaviour similar to males of other otariid species in the region.

    Preliminary discussion is conducted about the impact of the terms of the Convention on Nuclear safety, adopted by Diplomatic Conference in September 1994 in the International Atomic Energy Agency, on the regulatory action of Brazilian Nuclear Regulatory Body - CNEN. Following the Convention articles structure, the paper emphasizes technical aspects of the nuclear safety standards adopted in the licensing process of Brazilian Nuclear Power Plants. The recent experience in the issuance of Angra-1 NPP Permanent Operation Authorization is used to demonstrate that current safety standards in Brazil are in compliance with the international compromises and in agreement with what is expected by the so called Safety Culture.

    2001-01-01

    In the past, we carried out the safety assessment study at the site of Ulchin NPP against tsunamis on the basis of maximum earthquake magnitude 7 3/4 and available tsunamigenic earthquake fault parameters. But, recently, based on the seismic gap theory some geologists and seismologists warned that the earthquakes with larger magnitude than was expected might occur in the East Sea region. And, the need of re-evaluation of safety is suggested. In this study, to investigate the applicability of a finite difference model, we simulated the 1983 East Sea Tsunami at the Imwon Harbor where the maximum run-up height of tsunami was observed. The general agreement was obtained in the viewpoint of maxium wave run-up height. Finally, we evaluated the rise and drop of sea water level at the site of Ulchin NPP and concluded that the site of Ulchin NPP is safe against tsunami of the same magnitude of 1983 East Sea Tsunami

  5. Sweden's third national report under the Joint Convention on the safety of spent fuel management and on the safety of radioactive waste management. Swedish implementation of the obligations of the Joint Convention

    International Nuclear Information System (INIS)

    2008-01-01

    Article 32 of the Joint Convention calls for a self-assessment by each Contracting Party regarding compliance with the obligations of the Convention. Sweden's self-assessment has demonstrated compliance with all the obligations of the Convention, as shown in detail in sections B to J of this report. The Swedish existing nuclear power programme is since a few years under strong development. Large amounts are being invested in the 10 remaining operating reactors to prepare for long term operation and major programmes are going on to upgrade and uprate the plants. The former regulatory authorities, the Swedish Nuclear Power Inspectorate (SKI), and the Swedish Radiation Protection Authority (SSI), was merged into a new regulatory body, the Swedish Radiation Safety Authority, July 01, 2008. The new authority has been tasked with the responsibility and tasks from SKI and SSI. These developments create new challenges for the safety work of the licensees as well as for the regulatory authority. Even though comprehensive and very active programmes for the management and disposal of spent fuel and radioactive waste have been established, many challenges remain. Over the next 5-15 years several new facilities will be sited, constructed and taken into operation, e.g. an encapsulation plant and a repository for spent fuel. These activities will require substantial efforts for both the nuclear industry and the regulatory bodies. The generally positive impression reported to earlier review meetings under the Joint Convention still stands. Therefore, Sweden would like to point out the following as strong features in its national nuclear practice: The responsibility for safety is clearly defined in the Swedish legal framework. In order not to dilute the responsibility of the licence holders, the Swedish regulations are designed to define requirements to be achieved, not the detailed means to achieve them. Within the framework given by the regulations, the licence holders have to

  7. Treaty implementation applied to conventions on nuclear safety

    International Nuclear Information System (INIS)

    Montjoie, Michel

    2015-01-01

    Given that safety is the number one priority for the nuclear industry, it would seem normal that procedures exist to ensure the effective implementation of the provisions of the conventions on nuclear safety, as already exist for numerous international treaties. Unfortunately, these procedures are either weak or even nonexistent. Therefore, consideration must be given to whether this weakness represents a genuine deficiency in ensuring the main objective of these conventions, which is to achieve a high level of nuclear safety worldwide. But, before one can even address that issue, a prior question must be answered: does the specific nature of the international legal framework on nuclear safety automatically result in a lack of non-compliance procedures in international conventions on the subject? If so, the lack of procedures is justified, despite the drawbacks. The specific nature of the international law on nuclear safety, which in 1994 shaped the content of the CNS by notably not 'allowing' (even today) the incorporation of precise international rules have been taken into account. The next step is to examine whether the absence of non-compliance procedures (which could have been integrated into the text) is a hindrance in ensuring the objectives of the conventions on nuclear safety, and to examine the procedures that could have been used, based on existing provisions in other areas of international law (environmental law, financial law, disarmament law, human rights, etc.). International environmental law will be the main source of this study, as it has certain similarities with the international law on nuclear safety due to the sometimes vague nature of its obligations and irrespective of the fact that one of the purposes of nuclear safety is in particular to protect the environment from radiological hazards. Indeed, the provisions of the law on nuclear safety are mainly technical and designed to guarantee the normal operation of nuclear facilities

  8. The European single market of energy faced with conventional supply safety concepts

    International Nuclear Information System (INIS)

    Belyi, A.

    2004-01-01

    By analysing the context of the creation of the Single Energy Market, this article tries to understand the logic behind the coexistence of two energy safety concepts: (1) the financial gains of international trading; (2) the protection against supply shortage risks using domestic self-sufficiency policies. Both concepts are based on an informative context conditioned by the two crises, which mainly impact the security perceptions of today: the oil crisis in the seventies and the Californian crisis in 2001. They are based on opposite factors: anti-market behaviour in the first case and excessive competition in the second case. The nature of liberalization, of the relation-ship with non-EU producing countries and the perception of the dangers are inherent to such an informative context. (author)

    Full Text Available Currently, cattle systems have the challenge of improving their efficiency in order to satisfy the growing demand of livestock products while at the same time reducing their emissions. In order to estimate the main environmental impacts of bovine milk production and identify mitigation alternatives, a life cycle analysis (LCA was conducted to compare an intensive silvopastoral systems (ISS and a conventional system (CS in Colombia. The structure of ISO 14044 was followed, with four functional units (FU; the estimated environmental impacts were: land use (LU, use of non-renewable energy (UNRE and emissions of greenhouse gases (GHG. For all FU, the ISS had lower emissions of GHGs than the conventional system. To produce one kg of fat- and protein-corrected milk (FPCM the ISS emitted 1 less GHG than the CS (2.05 vs. 2.34 kg CO2-eq. Regarding the use of non-renewable energy, the ISS required only 63% of the energy used in the CS to produce one kg FPCM (3.64 vs. 5.81 kg Mj-1 whilst for land use, the CS was more efficient in all UF compared to the ISS. We conclude that in ISS there are lower environmental impacts per unit of product, emitting less GHG and having lower UNRE.

    2009-01-01

    Safety is an integral part of our working lives, and should be in our minds whatever job we do at CERN. Ultimately, safety is the responsibility of the Director General – your safety is my concern. That’s why I have this week appointed a new Safety Policy Committee (SAPOCO) that reflects the new Organizational structure of CERN. CERN’s Staff Rules and Regulations clearly lay out in chapter 3 the scope of safety at CERN as well as my responsibilities and yours in safety matters. At CERN, safety is considered in the broadest sense, encompassing occupational Health and Safety, environmental protection, and the safety of equipment and installations. It is my responsibility to put appropriate measures in place to ensure that these conditions are met. And it is the responsibility of us all to ensure that we are fully conversant with safety provisions applicable in our areas of work and that we comply with them. The appointment of a n...

    2006-01-09

    High throughput genome sequencing centers that were originally built for the Human Genome Project (Lander et al., 2001; Venter et al., 2001) have now become an engine for comparative genomics. The six largest centers alone are now producing over 150 billion nucleotides per year, more than 50 times the amount of DNA in the human genome, and nearly all of this is directed at projects that promise great insights into the pattern and processes of evolution. Unfortunately, this data is being produced at a pace far exceeding the capacity of the scientific community to provide insightful analysis, and few scientists with training and experience in evolutionary biology have played prominent roles to date. One of the consequences is that poor quality analyses are typical; for example, orthology among genes is generally determined by simple measures of sequence similarity, when this has been discredited by molecular evolutionary biologists decades ago. Here we discuss the how genomes are chosen for sequencing and how the scientific community can have input. We describe the PhIGs database and web tools (Dehal and Boore 2005a; http://PhIGs.org), which provide phylogenetic analysis of all gene families for all completely sequenced genomes and the associated 'Synteny Viewer', which allows comparisons of the relative positions of orthologous genes. This is the best tool available for inferring gene function across multiple genomes. We also describe how we have used the PhIGs methods with the whole genome sequences of a tunicate, fish, mouse, and human to conclusively demonstrate that two rounds of whole genome duplication occurred at the base of vertebrates (Dehal and Boore 2005b). This evidence is found in the large scale structure of the positions of paralogous genes that arose from duplications inferred by evolutionary analysis to have occurred at the base of vertebrates.

  14. Evaluation of stream discharges measurement using radioisotope and conventional method at Sungai Weng catchment area, Kedah

    2006-01-01

    A number of discharge measurements using radioisotope and current metering techniques at selected streams in Sg. Weng Experimental Catchment were conducted by MINT and JPS gauging teams starting from 2003-2005. This study aims to prepare stage-discharge relationships or rating curves of the selected streams during variable flow conditions. The rating curve of the stream is one of the important parameters and usually appraised in certain routine operations of hydrological studies. It may be used in the planning of water resources management and flood control scheme. The radioisotope method employed in this study involved the injection of short-lived radioisotope tracer, that is, technetium-99m ( 99m Tc having its half-life ∼ 6.023 hrs) which was supplied from a high activity technetium generator (55.5 Gbq). Measurement of stream discharges were concurrently undertaken by JPS staff using a current meter type 0TT-C2 mounted on a wading rod at selected gauging stations for comparison purposes. Methodologies from the two methods of discharge measurements, comparison of results and identifying the uncertainties (errors) in performing the measurement during low, medium and high turbulent flows were explained in this paper. Generally, the entire results of streamflow data (2003-2005) measured by both methods during low flows (Q 3 /s) exhibit almost comparable values to each other. However, for moderate flows (1.0 m 3 /s 3 /s), the different in gauging results are slightly higher using radioisotope method ( i.e. Q isotope > Q current meter and may goes up to 40%) , and during high turbulent flows (Q>6.0 m 3 /s) the radioisotope method presented more than 40% higher discharge values as compared to the measurement made by the conventional current-meter. Observation made on site anticipated that inaccurate gauging data measured by conventional means during high flow and turbulent conditions are expected. The average estimated measurement error associated with isotope method

    This probably is a suitable moment for work to begin on an international Convention in this area, although it is a difficult task. Generally speaking, the RADWASS (Radioactive Waste Safety Standards) Programme has achieved sufficient consensus, and might serve as an important basis for work in relation to the Convention. The Convention should not go into highly technical details since consensus at this level is more difficult at the present moment, although this will undoubtedly be achieved in the medium term. An important element of the Convention should be the regulation of movements of radioactive wastes at international level. (orig./HP)

  16. Safety at sea: oil spills, the tanker business and international regulations

    Energy Technology Data Exchange (ETDEWEB)

    Golomer, Olivier

    1994-02-01

    The tanker industry has been assailed in recent years with regulations, inspections, and many, many criticisms. The official objective of these pressures - the preservation of the environment from oil spills and oil contamination - is praiseworthy. However, many of these measures have proved inefficient or have led to ludicrous situations due in large part to them being targeted on crisis situations. Instead of emergency regulations spurred by sporadic disasters, both the tanker industry and protection of the environment need a set of economic instruments relying on a systematic assessment of risks. This paper focuses on these issues in the Very Large Crude Carrier segment of the tanker business. We start with a description of the industry and the actors in place, and then review the measures and policies adopted so far and their influence on the industry, especially in relation to freight rates. By analogy with other industries, a comprehensive approach to environmental hazards is then proposed. (Author)

  17. Clear progress in nuclear safety worldwide: Convention on nuclear safety concludes

    International Nuclear Information System (INIS)

    2002-01-01

    It has been concluded that a significant progress has been observed in a number of key areas, such as strengthened legislation, regulatory independence, the availability of financial resources, enhanced emergency preparedness and safety improvements at nuclear power plants built to earlier standards. The objective of the Convention is to achieve and maintain a high level of nuclear safety worldwide. During the two week Review Meeting, parties engaged in a 'peer review' process in which the National Reports from individual States were collectively examined and discussed, with written replies provided to all the questions raised. Clear improvement was noted in the quality of the National Reports, the number of questions and the openness and quality of discussion and answers. The Contracting Parties praised the IAEA's various safety review missions and services, which they use widely to help enhance the effectiveness of their national safety arrangements. Forty-six contracting parties participated at the Review Meeting with over 400 delegates attending, including many heads and senior officers from regulatory bodies and experts from industry. To date, the Convention has been signed by sixty-five States and ratified by fifty-four, representing 428 of the 448 nuclear power reactors worldwide

    A combination of computer analysis, degree of damage and approximate conversion to residual life expectancy gives acceptable results. There is considerable uncertainty in converting degree of damage to residual life expectancy, since structural component characteristics play a major role here. Structure damages play a major part in establishing the degree of damage. Damage categories are given, together with action if operations are to continue. Exhaustion calculations to TRD 508 are to be taken as conservative and as possible evidence of trends. 14 figs., 12 refs

    2017-02-01

    The current difficulty facing risk evaluations of Bacillus thuringiensis (Bt) crops on nontarget arthropods (NTAs) is the lack of criteria for determining what represents unacceptable risk. In this study, we investigated the biological parameters in the laboratory and field population abundance of Nilaparvata lugens (Hemiptera: Delphacidae) on two Bt rice lines and the non-Bt parent, together with 14 other conventional rice cultivars. Significant difference were found in nymphal duration and fecundity of N. lugens fed on Bt rice KMD2, as well as field population density on 12 October, compared with non-Bt parent. However, compared with the variation among conventional rice cultivars, the variation of each parameter between Bt rice and the non-Bt parent was much smaller, which can be easily seen from low-high bar graphs and also the coefficient of variation value (C.V). The variation among conventional cultivars is proposed to be used as a criterion for the safety assessment of Bt rice on NTAs, particularly when statistically significant differences in several parameters are found between Bt rice and its non-Bt parent. Coefficient of variation is suggested as a promising parameter for ecological risk judgement of IRGM rice on NTAs.

  1. Management of construction safety at RR site

    International Nuclear Information System (INIS)

    Pathak, B.C.; Khatsuriya, J.R.

    2016-01-01

    Construction industries are one of the most hazardous industries and hence, promotion of safety remains one of the greatest challenges facing construction industry today. According to ILO estimates: Each year at least 60,000 fatal accidents occur on construction sites around the world or one fatal accident every ten minutes. One in six fatal accidents at work occurs on a construction site. In industrialized countries, as many as 25-40 per cent of work related deaths occur on construction sites, even though the sector employs only 6-10 per cent of the workforce. The number of fatalities occurring from construction work in India is also quite disturbing. Though, the fall of person from height and through openings were the major causes for fatal /serious accidents, the risk of fatal accident involving material handling equipment, either during handling or its maintenance is also significantly high due to use of large number of material handling equipments during construction work.

    2011-07-01

    Older people reaching end-of-life status are particularly at risk from inter-related adverse effects of pharmacotherapy, including polypharmacy, inappropriate medications and adverse drug events. These adverse effects of pharmacotherapy may be highly detrimental, as well as highly expensive. End-of-life pharmacotherapy is sometimes perceived to be complex and challenging, probably unnecessarily. This relates in part to the poorly developed evidence base and lack of high-quality research in this area. In this article, we deal with some of the key issues relating to pharmacotherapy in end-of-life patients, namely (i) the guiding principles of drug selection, (ii) the main drugs and drug classes that are best avoided, (iii) the benefits of \\'oligopharmacy\\' (i.e. deliberate avoidance of polypharmacy) in end-of-life patients.

    2017-08-01

    Full Text Available In China, the oil and natural gas resources of Bohai Bay are mainly marginal oil fields. It is necessary to build both iceresistant and economical offshore platforms. However, there are many risks during the life cycle of offshore platforms due to the imperfect preliminary design for the Bohai Sea economical ice-resistant structures. As a result, the whole life-cycle design should be considered, including plan, design, construction, management and maintenance design. Based on the demand of existing codes and research of the basic design, structural ice-resistant performance and the reasonable management and maintenance, the life-cycle design theory is discussed. It was concluded that the life-cycle cost-effective optimum design proposed will lead to a minimum risk.

    Most arid and semi-arid regions are characterized by evaporites, which are assured sources for volatile organohalogens (VOX) [1]. These compounds play an important role in tropospheric and stratospheric chemistry. The Dead Sea between Israel and Jordan is the world's most famous and biggest all-season water covered salt lake. In both countries chemical plants like the Dead Sea Works and the Arab Potash Company are located at the southern part of the Dead Sea and mine various elements such as bromine and magnesium. Conveying sea water through constructed evaporation pans multifarious salts are enriched and precipitated. In contrast, the Northern basin and main part of the Dead Sea has remained almost untouched by industrial salt production. Its fresh water supply from the Jordan River is constantly decreasing, leading to further increased salinity. During a HALOPROC campaign (Natural Halogenation Processes in the Environment) we collected various samples including air, soils, sediments, halophytic plants, ground- and seawater from the Northern and Southern basin of the Israeli side of the Dead Sea. These samples were investigated for the occurrence of halocarbons using different analytical techniques. Most samples were analyzed for volatile organohalogens such as haloalkanes using gas chromatography- mass spectrometry (GC-MS). Interestingly, there is a strong enrichment of trihalomethanes (THM), especially all chlorinated and brominated ones and also the iodinated compound dichloroiodomethane were found in the Southern basin. In addition, volatile organic carbons (VOC) such as ethene and some other alkenes were analyzed by a gas chromatography-flame ionisation detector (GC-FID) to obtain further information about potential precursors of halogenated compounds. Halophytic plants were investigated for their potential to release chloromethane and bromomethane but also for their stable carbon and hydrogen isotope composition. For this purpose, a plant chamber was

    Biological disease-modifying antirheumatic drugs (bDMARDs) have shown diminished clinical response following an inadequate response (IR) to ≥1 previous bDMARD. Here, tofacitinib was compared with placebo in patients with an IR to conventional synthetic DMARDs (csDMARDs; bDMARD-naive) and in patients with an IR to bDMARDs (bDMARD-IR). Data were taken from phase II and phase III studies of tofacitinib in patients with rheumatoid arthritis (RA). Patients received tofacitinib 5 or 10 mg twice daily, or placebo, as monotherapy or with background methotrexate or other csDMARDs. Efficacy endpoints and incidence rates of adverse events (AEs) of special interest were assessed. 2812 bDMARD-naive and 705 bDMARD-IR patients were analysed. Baseline demographics and disease characteristics were generally similar between treatment groups within subpopulations. Across subpopulations, improvements in efficacy parameters at month 3 were generally significantly greater for both tofacitinib doses versus placebo. Clinical response was numerically greater with bDMARD-naive versus bDMARD-IR patients (overlapping 95% CIs). Rates of safety events of special interest were generally similar between tofacitinib doses and subpopulations; however, patients receiving glucocorticoids had more serious AEs, discontinuations due to AEs, serious infection events and herpes zoster. Numerically greater clinical responses and incidence rates of AEs of special interest were generally reported for tofacitinib 10 mg twice daily versus tofacitinib 5 mg twice daily (overlapping 95% CIs). Tofacitinib demonstrated efficacy in both bDMARD-naive and bDMARD-IR patients with RA. Clinical response to tofacitinib was generally numerically greater in bDMARD-naive than bDMARD-IR patients. The safety profile appeared similar between subpopulations. (NCT00413660, NCT00550446, NCT00603512, NCT00687193, NCT00960440, NCT00847613, NCT00814307, NCT00856544, NCT00853385).

    Full Text Available Consumers no longer look for food characterized only by health safety and proper nutritional value. As a result, an increased interest in traditional and regional food can be observed. The aim of this paper is to analyze the results of a comparative analysis of three types of hams: traditional products registered on the List of Traditional Products of the Polish Ministry of Agriculture and Rural Development, then products whose names, retail prices, appearance, and manufacturer’s description suggest traditional methods of production, and finally conventional hams. The results show that traditional hams are characterized by the highest nutritional value among the analyzed groups of products. They have the lowest water and a high protein content. In addition, traditional hams are distinguished by a low concentration of sodium chloride and no addition of phosphates. The residues of nitrites and nitrates indicate their moderate use in manufacturing processes.

    1998-01-01

    Full text of publication follows: in social science risk research more attention has been paid to examining how people in general perceive risks than to how they perceive possible measures to reduce risks and to increase their own safety. The latter area is, however, becoming increasingly important to understand, particularly in the light of current emphasis on individual responsibility in risk prevention and emergency preparedness. For example, in Sweden a major effort to increase safety awareness among the general public and to increase knowledge and skills in a number of safety-related areas is at present being planned. This effort is being undertaken as a cooperative effort between different authorities and institutions and is coordinated by the Swedish Rescue Services Agency. The intentions behind this and similar programmes raise a number of questions concerning how people view risks and safety measures in their own immediate environment. Knowledge of the factors affecting willingness to take precautions is important in the design of communication and information. The factors which are of significance may be risk-related and concern perceptions of personal risk, but may also be related to attitudes an beliefs concerning different precautionary measures, to perception of social norms and conventions as well as to personal experiences and values. This paper presents some data concerning views and actions among lay groups in relation to reducing risks and increasing safety. Factors affecting these views are discussed in the light of previous research and of empirical data from some recent studies. (author)

    The construction of wind turbines in shallow sea might jeopardize the life of mammals living nearby. The wave sound generated by each hammer impact to drive the pillars deep in the sea bottom can reach up to 200 decibels at 750 m away from the construction site. Repeated noises at this sound level is thought to be damaging for audition systems of sea mammals. The German authorities have launched a 4-year long program to find efficient technical solutions to damp sound waves. Various techniques have been tested in the Baltic sea and it appears that most techniques are efficient but some seem more relevant like the bubble curtain in which air bubbles generated around the site disturb the propagation of sound waves, or the balloon curtain in which air balloons plays the role of the bubbles, or the network of vertical pipes set around the construction site, or the sound-proofed sheath set around the pillar and hammer.

    Full Text Available Organizational safety climate will produce spillover effects and thus affect the individuals’ performance in their family life. As a mainstay industry in many countries, the construction industry has a considerable number of employees and the research on the spillover effects from the safety climate of construction enterprises has important theoretical and practical significance to improve the safety behavior of construction employees in their family life. In this study, we thoroughly reviewed the literature to identify the dimensions of the safety climate spillover, obtain empirical data of the construction employees through a questionnaire survey, and use the data analysis method to study the spillover effects of the safety climate of the construction enterprises from the perspective of work–family integration, and reveal its influence mechanism. This study developed a questionnaire to measure the safety climate spillover of the construction enterprises including two dimensions, namely values and behaviors, with nine measured items. Management commitment and safety attitude in the safety climate were positively related to the spillover, and management commitment had the greatest impact on the spillover, while the other components were not significantly related to the spillover. The two forms of spillover, values and behaviors, were mutually influential, and the safety climate had a more significant impact on the values. This paper contributes to the current safety research by developing a factor structure of spillover effects of the safety climate on the lives of construction employees, thus providing a more profound interpretation of this crucial construct in the safety research domain. The spillover effects of the safety climate’s measurement questionnaire serve as an important tool for spillover among construction enterprises. Findings can facilitate improvement in both theories and practices related to the spillover effects of the

    Fresh produce is usually eaten raw without cooking or heating, which may increase the probability of foodborne infection. The microbiological quality of 11 types of fresh, raw vegetables (romaine lettuce, sesame leaves, crown daisy, garlic chives, iceberg lettuce, cabbage, broccoli, leek, chili pepper, capsicum, and zucchini) purchased at retail markets in Iksan, Korea as affected by cultivation method (environmentally friendly vegetables [organic, pesticide-free, and low-pesticide vegetables] and conventionally grown vegetables) and harvest season was determined. Escherichia coli O157:H7 and Salmonella were not detected in all samples of vegetables tested. Aerobic mesophiles (>6 log cfu/g) were detected in environmentally friendly romaine lettuce and crown daisy and environmentally friendly and conventionally grown garlic chives, which also contained coliforms (>3 log cfu/g). Sesame leaf and crown daisy (regardless of cultivation method), as well as conventionally grown romaine lettuce and leek, contained >1 log cfu/g of E. coli. The overall microbiological quality of environmentally friendly and conventionally grown vegetables was not significantly different (P > 0.05). However, there were seasonal effects on populations of coliforms and generic E. coli on vegetables. The greatest numbers of microorganisms were isolated from environmentally friendly or conventionally grown vegetables purchased in winter. The vegetables, regardless of cultivation method or season, should be subjected to appropriate antimicrobial treatment to enhance their microbial safety. © 2014 Institute of Food Technologists®

Ectosymbionts of seven species associated with 60.7% of S. gigantea (n=28, with a mean of 2.4 per anemone and 3.9 per occupied anemone. Anemones hosting one or more ectosymbionts did not differ significantly in size from anemones lacking ectosymbionts and there was no significant correlation between anemone size and the number of ectosymbionts. Of 67 ectosymbionts observed, the sea cucumber Stichopus vastus comprised 23.9%, followed by the shrimp Thor amboinensis (20.9%, unidentified hermit crabs (Paguroidea; 20.9%, the cardinalfish Ostorhinchus novemfasciatus (20.9%, the shrimp Periclimenes brevicarpalis (9.0%, the sea cucumber Holothuria hilla (3.0%, and an unidentified brachyuran crab (1.5%. This study documents the first records of S. vastus, H. hilla, and O. novemfasciatus associating with S. gigantea, and the first locality records of S. gigantea, T. amboinensis, P. brevicarpalis, and S. vastus for Kosrae. Because humans often harvest S. gigantea for food at Kosrae, we recommend protecting the symbiotic assemblage of S. gigantea by establishing a sustainable system of harvesting.

    2018-01-01

    My evolution from electrical engineering student to limnologist and then to oceanographer was a consequence of generous mentoring, which led to my use of the 15N tracer technique to measure nitrogen fixation in aquatic systems. The concept of new and regenerated production arose when I applied this method to measure nitrate and ammonium uptake in marine ecosystems. I then showed that enzyme kinetics could be applied to algal nitrogen uptake and used a silicate pump to explain silicate limitation of diatoms in coastal and equatorial upwelling systems. These concepts are now recognized as modern nutrient paradigms in biogeochemical oceanography. My interest in nutrients required field studies and led to my passion for the study of upwelling ecosystems and the establishment of two major international programs, with numerous advisors, collaborators, and students helping along the way.

    Highlights: • Development of data-intensive bottom-up life cycle assessment model. • Quantification of well-to-wheel GHG emissions for five North American crudes. • Allocation of emissions to transportation fuels (gasoline, diesel, and jet fuel). • California’s Kern County heavy oil is the most GHG intensive of the crudes. - Abstract: A life cycle assessment (LCA) is an extremely useful tool to assess the greenhouse gas (GHG) emissions associated with all the stages of a crude oil’s life from well-to-wheel (WTW). All of the WTW life cycle stages of crude oil consume energy and produce significant amounts of GHG emissions. The present study attempts to quantify the WTW life cycle GHG emissions for transportation fuels derived from five North American conventional crudes through the development of an LCA model called FUNNEL-GHG-CCO (FUNdamental Engineering PrinciplEs-based ModeL for Estimation of GreenHouse Gases in Conventional Crude Oils). This model estimates GHG emissions from all the life cycle stages from recovery of crude to the combustion of transportation fuels in vehicle engines. The contribution of recovery emissions in the total WTW GHG emissions ranges from 3.12% for Mars crude to 24.25% for California’s Kern County heavy oil. The transportation of crude oil and refined fuel contributes only 0.44–1.73% of the total WTW life cycle GHG emissions, depending on the transportation methods and total distance transported. The GHG emissions for refining were calculated from the amount of energy use in the refining of crude oil to produce transportation fuels. All the upstream GHG emissions were allocated to gasoline, diesel, and jet fuel. Refining GHG emissions vary from 13.66–18.70 g-CO 2 eq/MJ-gasoline, 9.71–15.33 g-CO 2 eq/MJ-diesel, and 6.38–9.92 g-CO 2 eq/MJ-jet fuel derived from Alaska North Slope and California’s Kern County heavy oil, respectively. The total WTW life cycle GHG emissions range from 97.55 g-CO 2 eq

    Fabra Observatory , located in a promontory at 411 meters above sea level in the outskirts of Barcelona, hosts a continuous climate record since 1913. Additionally, it has been recording since 1996 simultaneous temperature and precipitation data with conventional instruments and automated systems. The automatization of recording sites employed with climatological purposes is happening elsewhere in the country and across the globe. Unfortunately, in most cases long lasting parallel measurements, are not kept. Thereafter, this site offers an excellent opportunity to study the impact of the introduction of Automatic Weather Stations (AWS). The conventional station (CON) equips a liquid in glass thermometer, located inside a standard Stevenson screen. The automatic measurements (AWS) have been taken using MCV-STA sensors sheltered in a MCV small plate-like ventilated screen between 1996 and the end of July 2007. For our analysis, this MCV period is split in two (T1, T2) due to an obvious jump in the differences AWS-CON in October 2002, produced by unknown reasons. From August 2007 to the present (T3), a Vaisala HMP45AL sensor was placed inside a Stevenson Screen and used for automatic measurements. For daily maximum temperatures, the median differences reach 3.2°C in T1, 1.1°C in T2 and merely -0.1°C in T3. In this later period, 94% of the differences are comprised in a ±0.5°C range, compared to 23% in T2 and only 6% in T1. It is interesting to note how the overheating of the MCV screen dominates the difference series, as 85% of the AWS values taken in T1 and T2 are warmer than the conventional measurements, contrasting with only 27% of cases during T3, when the automated measurements were taken inside a Stevenson screen. These differences are highly temperature dependent: low (high) AWS temperatures are associated with small (large) differences with the CON series. This effect is also evident if temperatures are analyzed by seasons: summer differences are much

    To further expand upon the literature in this field and to develop a platform for bioproduct LCA, we developed LCA results for ten bioproducts produced either from algal glycerol or from corn stover-derived sugars. We used Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREETTM) model as the platform for this study. The data and calculations reported herein are available to GREET users in a bioproducts module included in the fall 2015 GREET release. This report documents our approach to this analysis and the results. In Chapter 2, we review the process we underwent to select the bioproducts for analysis based on market and technology readiness criteria. In Chapter 3, we review key parameters for production of the two feedstocks we considered: corn stover and algae. Given the lack of publicly available information about the production of bioproducts, which is caused in large part by the emerging nature of the industry, we developed Aspen Plus® simulations of the processes that could be used to produce each bioproduct. From these simulations, we extracted the energy and material flows of these processes, which were important inputs to the GREET bioproducts module. Chapter 4 provides the details of these Aspen Plus simulations. It is important to compare the LCA results for bioproducts to those for their petroleum counterparts. We therefore also developed material and energy flow data for conventional products based mostly on the literature. These data are described in Chapter 5 and are also included in the GREET bioproducts module. In Chapter 6, we present results from this analysis and examine areas for refinement and future research.

The existing reactors would be allowed to continue operating, but would not be replaced at the end of their life span. The major part of nuclear research in Switzerland is performed at the Paul Scherrer Institute (PSI). These include research related to spent fuel and radioactive waste management. PSI operates several nuclear facilities: the research reactor PROTEUS, a hot laboratory, and waste management facilities. The former research reactors DIORIT and SAPHIR are in the state of decommissioning. Two small research reactors exist at the University of Basel (Uni BS) and at the Swiss Federal Institute of Technology Lausanne (EPFL) for teaching purposes. The former Lucens experimental NPP was decommissioned and dismantled after experiencing a loss of coolant accident in 1969. This site was declassified and released for non-nuclear activities, as well as the one of the small research reactor at the University of Geneva.

    Cieslak, W. R.; Street, H. K.

    A Li/SOCl2 'D' cell for applications requiring 10 to 15 years life at very low drain rates, typically less than 150 microA, were developed. Maximizing cell safety and reliability, while delivering very good energy density, were the goals. These goals were achieved by designing the cell to be application specific. The low-rate cell was optimized to deliver up to 16 Ah at drain rates of less than 70 mA. By virtue of its low surface area, 145 cm(sup 2), the cell demonstrated excellent safety behavior. Safety testing was performed on individual cells as well as on two-cell and four-cell batteries. Single cells did not vent when short-circuited. Benign venting in a two cell string was produced, but only when the string was partially discharged before shorting. The vent mechanism is a 300 psi rupture pressure burst disc manufactured by BS&B Safety Systems. Benign venting is defined as full opening of the 3/8 in. dia vent hole without deformation of the case. Material is expelled from the cell without flame, and the cell stack remains largely intact. Venting of the Sandia-designed low rate cell was not produced under any other abuse test conditions. The vent functions as an ultimate safety mechanism in the case of severe abuse, but resistance to venting under normal use and mild abuse conditions is key to the achievement of high reliability.

  2. Impact of life history traits on gene flow: A multispecies systematic review across oceanographic barriers in the Mediterranean Sea

    KAUST Repository

    Pascual, Marta

    2017-05-10

    Marine species can demonstrate strong genetic differentiation and population structure despite the hypothesis of open seas and high connectivity. Some suggested drivers causing the genetic breaks are oceanographic barriers and the species\\' biology. We assessed the relevance of seven major oceanographic fronts on species connectivity while considering their dispersal capacity and life strategy.We systematically reviewed the scientific articles reporting population genetic differentiation along the Mediterranean Sea and across the Atlantic-Mediterranean transition. We retained those considering at least one sampling locality at each side of an oceanographic front, and at least two localities with no-front between them to correctly assess the effect of the front. To estimate the impact of life history characteristics affecting connectivity we considered the planktonic larval duration (PLD) and adult life strategy.Oceanographic barriers in the Mediterranean Sea seem to reduce gene flow globally; however, this effect is not homogeneous considering the life history traits of the species. The effect of the oceanographic fronts reduces gene flow in highly mobile species with PLD larger than 2-4 weeks. Benthic sessile species and/or with short PLD (< 2 weeks) have more significant genetic breaks between localities than species with higher motility; however, genetic differentiation occurs independently of the presence of a front.Genetic connectivity is important for populations to recover from anthropogenic or natural impacts. We show that species with low mobility, mostly habitat-formers, have high genetic differentiation but low gene flow reduction mediated by the front, therefore, considering the importance of these species, we emphasize the vulnerability of the Mediterranean ecosystems and the necessity of protection strategies based on the whole ecosystem.

    Highlights: ► This paper suggests the expectation algorithm of SSCs life time for decommissioning safety of nuclear facilities. ► The life time of SSCs can be estimated by using fuzzy theory. ► The estimated results depend on the membership functions and performance characteristic functions. - Abstract: This paper suggests the estimation algorithm for life time of structure, system and components (SSCs) for decommissioning safety of nuclear facilities using the performance data of linguistic languages and fuzzy theory. The fuzzy estimation algorithm of life time can be easily applicable but the estimated results depend on the relevant membership functions and performance characteristic functions. This method will be expected to be very useful for maintenance and decommissioning of nuclear facilities’ SSCs as a safety assessment tool.

    The Greenpeace Nuclear Free Seas Campaign is outlined. The campaign aims to bring the environmental hazards from nuclear submarines and naval ships carrying nuclear weapons to public attention. Worldwide there are 544 nuclear reactor ships or submarines each with the potential to meltdown with serious environmental consequences. One meltdown is known to have occurred. Five reactors have been abandoned on the sea bed. Nuclear powered submarines are based at Rosyth, Faslane, Holy Loch, Plymouth and Portsmouth and routinely come into and out of those harbours. There have also been accidents involving nuclear weapons on board submarines, aircraft carriers or destroyers which carry nuclear depth bombs and free fall bombs. The Royal Navy's accident emergency plans for nuclear naval bases are inadequate. There is a threat to the environment when the reactors are decommissioned. There are no clear plans as to how to deal with the decommissioning of the submarines or ships although the fuel rods have been removed from the first British nuclear submarine, Dreadnought. (U.K.)

    Purpose: To compare health-related quality-of-life (HRQOL) outcomes of patients with oropharyngeal squamous cell carcinoma treated using intensity-modulated radiotherapy (IMRT) vs. conventional radiotherapy (CRT). Patients and Methods: Patients with oropharyngeal squamous cell carcinoma were extracted from the database of an ongoing longitudinal Outcome Assessment Project. Eligible criteria included (1) treated with definitive radiation, and (2) provided 12-month posttreatment HRQOL data. Excluded were 7 patients who received IMRT before October 1, 2002, during this institution's developmental phase of the IMRT technique. The HRQOL outcomes of patients treated with IMRT were compared with those of patients who received CRT. Results: Twenty-six patients treated using IMRT and 27 patients treated using CRT were included. Patients in the IMRT group were older and had more advanced-stage diseases and more patients received concurrent chemotherapy. However, the IMRT group had higher mean Head and Neck Cancer Inventory scores (which represent better outcomes) for each of the four head-and-neck cancer-specific domains, including eating, speech, aesthetics, and social disruption, at 12 months after treatment. A significantly greater percentage of patients in the CRT group had restricted diets compared with those in the IMRT group (48.0% vs. 16.0%, p = 0.032). At 3 months after treatment, both groups had significant decreases from pretreatment eating scores. However, the IMRT group had a significant improvement during the first year, but the CRT group had only small improvement. Conclusions: Proper delivery of IMRT can improve HRQOL for patients with oropharyngeal cancer compared with CRT

    Safety management is the term used for the measures required to ensure that an acceptable level of safety is maintained throughout the life of an installation, including decommissioning. The safety culture concept and its implementation are described in part one of the paper. The principles of safety are now quite well known and are implemented worldwide. It leads to a situation where harmonization is being achieved as indicated by the entry into force of the Convention on Nuclear Safety. To go beyond the present nuclear safety levels, management of safety and safety culture will be the means for achieving progress. Recent events which took place in major nuclear power countries have shown the importance of the management and the consequences on safety. At the same time, electricity deregulation is coming and will impact on safety through reductions in staffing and in operation and maintenance cost at nuclear installations. Management of safety as well as its control and monitoring by the safety authorities become a key to the future of nuclear energy.(author)

    Conventional anesthetic nerve block injections into the mandibular foramen risk causing nerve damage. This study aimed to compare the efficacy and safety of the anterior technique (AT) of inferior alveolar nerve block using felypressin-propitocaine with a conventional nerve block technique (CT) using epinephrine and lidocaine for anesthesia via the mandibular foramen. Forty healthy university students with no recent dental work were recruited as subjects and assigned to two groups: right side CT or right side AT. Anesthesia was evaluated in terms of success rate, duration of action, and injection pain. These parameters were assessed at the first incisor, premolar, and molar, 60 min after injection. Chi-square and unpaired t-tests were used for statistical comparisons, with a P value of nerve block techniques generated comparable success rates for the right mandible, with rates of 65% (CT) and 60% (AT) at both the first molar and premolar, and rates of 60% (CT) and 50% (AT) at the lateral incisor. The duration of anesthesia using the CT was 233 ± 37 min, which was approximately 40 min shorter than using the AT. This difference was statistically significant (P < 0.05). Injection pain using the AT was rated as milder compared with the CT. This difference was also statistically significant (P < 0.05). The AT is no less successful than the CT for inducing anesthesia, and has the added benefits of a significantly longer duration of action and significantly less pain.

  20. Differences in safety margins between nuclear and conventional design standards with regards to seismic hazard definition and design criteria

    With the surging interest in new build nuclear all over the world and a permanent interest in earthquake resistance of nuclear plants, there is a need to quantify the safety margins in nuclear buildings design in comparison to conventional buildings in order to increase the public confidence in the safety of nuclear power plants. Nuclear (CAN3-N289 series) and conventional (NBCC 2005) seismic standards have different approaches regarding the design of civil structures. The origin of the differences lays in the safety philosophy behind the seismic nuclear and conventional standards. Conventional seismic codes contain the minimal requirement destined primarily to safeguard against major structural failure and loss of life. It doesn't limit damage to a certain acceptable degree or maintain function. Nuclear seismic code requires that structures, systems and components important to safety, withstand the effects of earthquakes. The requirement states that for equipment important to safety, both integrity and functionality should be ascertained. The seismic hazard is generally defined on the basis of the annual probability of exceedence (return period). There is a major difference on the return period and the confidence level for design earthquakes between the conventional and the nuclear seismic standards. The seismic design criteria of conventional structures are based on the use of Force Modification Factors to take into account the energy dissipation by incursion in non-elastic domain and the reserve of strength. The use of such factors to lower intentionally the seismic input is consistent with the safety philosophy of the conventional seismic standard which is the 'non collapse' rather than the integrity and/or the operability of the structures or components. Nuclear seismic standard requires that the structure remain in the elastic domain; energy dissipation by incursion in non-elastic domain is not allowed for design basis earthquake conditions. This is

    Volume overload is a common complication associated with heart failure (HF) and is recommended to be treated with loop or thiazide diuretics. However, use of diuretics can cause serum electrolyte imbalances and diuretic resistance. Tolvaptan, a selective, oral, non-peptide vasopressin V2-receptor antagonist, offers a new option for treating volume overload in HF patients. The aim of this study was to investigate the efficacy and safety of tolvaptan in Japanese HF patients with volume overload. Fifty-one HF patients with volume overload, despite using conventional diuretics, were treated with 15 mg/day tolvaptan for 7 days. If the response was insufficient at Day 7, tolvaptan was continued for a further 7 days at either 15 mg/day or 30 mg/day. Outcomes included changes in body weight, symptoms and safety parameters. Thirty-six patients discontinued treatment within 7 days, therefore 15 patients entered the second phase of treatment. In two patients, tolvaptan was increased to 30 mg/day after 7 days. Body weight was reduced on Day 7 (-1.95 ± 1.98 kg; n = 41) and Day 14 (-2.35 ± 1.44 kg; n = 11, 15 mg/day). Symptoms of volume overload, including lower limb edema, pulmonary congestion, jugular venous distention and hepatomegaly, were improved by tolvaptan treatment for 7 or 14 days. Neither tolvaptan increased the incidence of severe or serious adverse events when administered for 7-14 days. This study confirms the efficacy and safety of 15 mg/day tolvaptan for 7-14 days in Japanese HF patients with volume overload despite conventional diuretics.

  2. Organization and conduct of IAEA fire safety reviews at nuclear power plants

    International Nuclear Information System (INIS)

    1998-01-01

    The importance of fire safety in the safe and productive operation of nuclear power plants is recognized worldwide. Lessons learned from experience in nuclear power plants indicate that fire poses a real threat to nuclear safety and that its significance extends far beyond the scope of a conventional fire hazard. With a growing understanding of the close correlation between the fire hazard in nuclear power plants and nuclear safety, backfitting for fire safety has become necessary for a number of operating plants. However, it has been recognized that the expertise necessary for a systematic independent assessment of fire safety of a NPP may not always be available to a number of Member States. In order to assist in enhancing fire safety, the IAEA has already started to offer various services to Member States in the area of fire safety. At the request of a Member State, the IAEA may provide a team of experts to conduct fire safety reviews of varying scope to evaluate the adequacy of fire safety at a specific nuclear power plant during various phases such as construction, operation and decommissioning. The IAEA nuclear safety publications related to fire protection and fire safety form a common basis for these reviews. This report provides guidance for the experts involved in the organization and conduct of fire safety review services to ensure consistency and comprehensiveness of the reviews

    Most component failures stem from effects of one or multiple ageing mechanism(s). Ageing management is one of the most robust measures to prevent failure and to maintain and increase safety of nuclear power plants. Based on Nuclear Safety Guideline on Ageing Management (NS-G-2.12) published by IAEA in 2009, the paper summarizes main ageing management activities required for all stages of life cycle of NPPs, including design, construction/manufacture, commissioning, operation, life extension for long-term operation and decommissioning. Interactive relations of ageing management in successive stages are analyzed. Implementation of the IAEA Guideline in comprehensive way will bring new challenges to design conception, modes of construction, manufacture, commissioning, equipment qualification, O and M, licensing, life extension and decommissioning for NPPs, however, it will be beneficial to enhance nuclear safety level, especially to promote development of nuclear power in China in a safe, reliable, profitable and sustainable way.

  7. Improved safety at CERN

    CERN Multimedia

    2006-01-01

    As announced in Weekly Bulletin No. 43/2006, a new approach to the implementation of Safety at CERN has been decided, which required taking some managerial decisions. The guidelines of the new approach are described in the document 'New approach to Safety implementation at CERN', which also summarizes the main managerial decisions I have taken to strengthen compliance with the CERN Safety policy and Rules. To this end I have also reviewed the mandates of the Safety Commission and the Safety Policy Committee (SAPOCO). Some details of the document 'Safety Policy at CERN' (also known as SAPOCO42) have been modified accordingly; its essential principles, unchanged, remain the basis for the safety policy of the Organisation. I would also like to inform you that I have appointed Dr M. Bona as the new Head of the Safety Commission until 31.12.2008, and that I will proceed soon to the appointment of the members of the new Safety Policy Committee. All members of the personnel are deemed to have taken note of the d...

  8. Application of system safety engineering techniques for hazard prevention at the Superconducting Super Collider

    International Nuclear Information System (INIS)

    Hendrix, B.L.

    1991-01-01

    A primary goal of the Superconducting Super Collider Laboratory (SSCL) is to establish an exemplary safety program. Achieving this goal requires leadership, planning, coordination, and technical know-how. To ensure that safety is an inherent part of the design, the Environment, Safety and Health Office employs a systems engineering discipline and process known as System Safety. The goal of System Safety - hazard prevention - is accomplished by analyzing systems to identify hazards and to evaluate design and procedural options and countermeasures to prevent, eliminate, mitigate, or control hazards and risks. Establishment of safety and human factors design criteria at the outset of the project prevents unsafe designs and safety violations, reduces risks, and helps in avoiding costly design changes later. This process requires a considerable amount of coordination with a variety of technical disciplines and safety professionals to integrate methods of hazard prevention, mitigation, and risk reduction throughout the system life-cycle

    Gil, Luiz Fernando; Sarendranath, Alvin; Neiva, Rodrigo; Marão, Heloisa F; Tovar, Nick; Bonfante, Estevam A; Janal, Malvin N; Castellano, Arthur; Coelho, Paulo G

    This study evaluated whether simplified drilling protocols would provide comparable histologic and histomorphometric results to conventional drilling protocols at a low rotational speed. A total of 48 alumina-blasted and acid-etched Ti-6Al-4V implants with two diameters (3.75 and 4.2 mm, n = 24 per group) were bilaterally placed in the tibiae of 12 dogs, under a low-speed protocol (400 rpm). Within the same diameter group, half of the implants were inserted after a simplified drilling procedure (pilot drill + final diameter drill), and the other half were placed using the conventional drilling procedure. After 3 and 5 weeks, the animals were euthanized, and the retrieved bone-implant samples were subjected to nondecalcified histologic sectioning. Histomorphology, bone-to-implant contact (BIC), and bone area fraction occupancy (BAFO) analysis were performed. Histology showed that new bone was formed around implants, and inflammation or bone resorption was not evident for both groups. Histomorphometrically, when all independent variables were collapsed over drilling technique, no differences were detected for BIC and BAFO; when drilling technique was analyzed as a function of time, the conventional groups reached statistically higher BIC and BAFO at 3 weeks, but comparable values between techniques were observed at 5 weeks; 4.2-mm implants obtained statistically higher BAFO relative to 3.75-mm implants. Based on the present methodology, the conventional technique improved bone formation at 3 weeks, and narrower implants were associated with less bone formation.

  10. The Safety Assessment of Long term Interim Storage at Sellafield

    International Nuclear Information System (INIS)

    Buchan, Andrew B.

    2014-01-01

    The Sellafield site comprises a wide range of nuclear facilities, including operating facilities associated with the Magnox reprocessing programme, the Thermal Oxide Reprocessing Plant (THORP) and a range of waste treatment plants. The operational life of some of the site facilities currently extends to 2120, requiring the retrieval, treatment, consolidation and safe extended storage of a variety of radioactive materials. Sellafield has utilised its existing safety assessment processes to inform and prioritise studies into beyond design basis events and resilience evaluation required following Fukushima by UK regulators and industry bodies such as WANO. There are significant differences between NPPs, for which the ENSREG 'stress tests' were originally intended, and the Sellafield site which is instead centered around two reprocessing facilities (Magnox and THORP), with a supporting infrastructure of waste processing and storage facilities, coupled with a legacy of high hazard older facilities. In the former case the consequences of a catastrophic failure are promptly realised, leading to significant problems such as fuel failure / meltdown in AGRs and LWRs respectively in the event of complete loss of cooling. At Sellafield, the processes are carried out at comparatively low temperatures and pressures with relatively low rates of change following any loss of cooling. Instead the consequences of catastrophic failure at Sellafield are more directly related to the very large inventories of radioactive materials, including high level liquid wastes and unprocessed fuels, present in specific plants and to the condition of the ageing assets, holding legacy wastes. The paper will consider how a number of analysis techniques have been used to establish a safety case for fault and accident conditions, i.e. design basis analysis (DBA), probabilistic safety analysis (PSA) and severe accident analysis (SAA) DBA is focused on the key safety measures for those initiating faults

  11. Life cycle air quality impacts of conventional and alternative light-duty transportation in the United States.

    Tessum, Christopher W; Hill, Jason D; Marshall, Julian D

    2014-12-30

    Commonly considered strategies for reducing the environmental impact of light-duty transportation include using alternative fuels and improving vehicle fuel economy. We evaluate the air quality-related human health impacts of 10 such options, including the use of liquid biofuels, diesel, and compressed natural gas (CNG) in internal combustion engines; the use of electricity from a range of conventional and renewable sources to power electric vehicles (EVs); and the use of hybrid EV technology. Our approach combines spatially, temporally, and chemically detailed life cycle emission inventories; comprehensive, fine-scale state-of-the-science chemical transport modeling; and exposure, concentration-response, and economic health impact modeling for ozone (O3) and fine particulate matter (PM2.5). We find that powering vehicles with corn ethanol or with coal-based or "grid average" electricity increases monetized environmental health impacts by 80% or more relative to using conventional gasoline. Conversely, EVs powered by low-emitting electricity from natural gas, wind, water, or solar power reduce environmental health impacts by 50% or more. Consideration of potential climate change impacts alongside the human health outcomes described here further reinforces the environmental preferability of EVs powered by low-emitting electricity relative to gasoline vehicles.

    Analysis of the risks of sea-level rise favours conventionally measured metrics such as the area of land that may be subsumed, the numbers of properties at risk, and the capital values of assets at risk. Despite this, it is clear that there exist many less material but no less important values at risk from sea-level rise. This paper re-theorises these multifarious social values at risk from sea-level rise, by explaining their diverse nature, and grounding them in the everyday practices of people living in coastal places. It is informed by a review and analysis of research on social values from within the fields of social impact assessment, human geography, psychology, decision analysis, and climate change adaptation. From this we propose that it is the ‘lived values’ of coastal places that are most at risk from sea-level rise. We then offer a framework that groups these lived values into five types: those that are physiological in nature, and those that relate to issues of security, belonging, esteem, and self-actualisation. This framework of lived values at risk from sea-level rise can guide empirical research investigating the social impacts of sea-level rise, as well as the impacts of actions to adapt to sea-level rise. It also offers a basis for identifying the distribution of related social outcomes across populations exposed to sea-level rise or sea-level rise policies

  14. Impacts of Global Warming and Sea Level Rise on Service Life of Chloride-Exposed Concrete Structures

    Directory of Open Access Journals (Sweden)

    Xiao-Jian Gao

    2017-03-01

    Full Text Available Global warming will increase the rate of chloride ingress and the rate of steel corrosion of concrete structures. Furthermore, in coastal (atmospheric marine zones, sea level rise will reduce the distance of concrete structures from the coast and increase the surface chloride content. This study proposes a probabilistic model for analyzing the effects of global warming and sea level rise on the service life of coastal concrete structures. First, in the corrosion initiation stage, an improved chloride diffusion model is proposed to determine chloride concentration. The Monte Carlo method is employed to calculate the service life in the corrosion initiation stage; Second, in the corrosion propagation stage, a numerical model is proposed to calculate the rate of corrosion, probability of corrosion cracking, and service life. Third, overall service life is determined as the sum of service life in the corrosion initiation and corrosion propagation stages. After considering the impacts of global warming and sea level rise, the analysis results show that for concrete structures having a service life of 50 years, the service life decreases by about 5%.

    Safe management of operating lifetimes of Nuclear Power Plants is a subject of prime interests. As the design life of the Nuclear Power Plant will be ended in 2008, an appropriate procedure for the design life re-assessment or lifetime extension is necessary in Korea. Therefore, the objective of this work is to develop procedural requirements which can be applied to the regulation of lifetime management or life extension of Nuclear Power Plants in Korea. Review on the linkage of the PSR with the extension of the operating lifetime of Nuclear Power Plants was performed to enhance the utilization of PSR results and analysis of the insufficiencies in the license rule in Korea.

  16. Safety aspects of the desalination of sea water using nuclear energy

    International Nuclear Information System (INIS)

    Carnino, A.; Gasparini, N.

    2001-01-01

    The nuclear plants for desalination to be built in the future will have to meet the standards of safety required for the best nuclear power plants currently in operation or being designed. Some specific characteristics of desalination plants such as siting and coupling require particular consideration from a safety point of view, and further safety studies will be needed when the type and size of the reactor are determined. The current safety approach, based on the defence in depth strategy, has been shown to be a sound foundation for the safety and protection of public health, and gives the plant the capability of dealing with a large variety of sequences, even beyond the design basis. The Department of Nuclear Safety of the IAEA is involved in many activities, the most important of which are to establish safety standards, and to provide various safety services and technical knowledge in many Technical Co-operation assistance projects. The department is also involved in other safety areas, notably in the field of future reactors. The IAEA is carrying out a project on the safety of new generation reactors, including those used for desalination, with the objective of fostering an exchange of information on safety approaches, promoting harmonization among Member States and contributing towards the development and revision of safety standards and guidelines for nuclear power plant design. The safety, regulatory and environmental concerns in nuclear powered desalination are those related directly to nuclear power plants, with due consideration given to the coupling process. The protection of product water against radioactive contamination must be ensured. An effective infrastructure, including appropriate training, a legal framework and regulatory regime, is a prerequisite to considering use of nuclear power for desalination plants, also in those countries with limited industrial infrastructures and little experience in nuclear technology or safety.

    1981-01-01

    The need for internationally acceptable standards and regulations for preventing pollution of the sea by radioactive materials was recognized by the United Nations Conference on the Law of the Sea, which adopted the Convention on the High Seas in April 1958. Article 25 of the Convention provides that ''every State shall take measures to prevent pollution of the seas from the dumping of radioactive wastes, taking into account any standards and regulations which may be formulated by the competent international organizations.'' The Conference also adopted a resolution recommending that the IAEA pursue studies and take action to assist States in controlling the discharge of radioactive materials into the sea. When the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter was adopted at the Intergovernmental Conference in London, 1972, the IAEA was given specific responsibilities to define criteria and standards for dealing with the questions of sea disposal of radioactive wastes. The IAEA Definition and Recommendations concerning ''high-level radioactive wastes or other high-level radioactive matter unsuitable for dumping at sea'' identify material, the radioactive content of which is at such a level that the Parties to the Convention would wish to prevent any participating State from issuing a special permit even after a detailed appraisal of the safety of the proposed operation, and even for the sector of the marine environment furthest removed from man, i.e. the deep sea with depth greater than 4000 m. Some historical background to these problems is discussed and some of the Japanese findings of the deep sea survey in the Pacific are introduced for comparison with the North Atlantic data which formed a basis of the IAEA Definition and Recommendations for the London Dumping Convention

    We have developed a Li/SOCl{sub 2} ``D`` cell for applications requiring 10 to 15 years life at very low drain rates, typically less than 150 {mu}A. Maximizing cell safety and reliability, while delivering very good energy density, have been the goals of our study. We have achieved these goals by designing the cell to be application specific. The low-rate cell has been optimized to deliver up to 16 Ah at drain rates of less than 70 mA. By virtue of its low surface area, 145 cm{sub 2}, the cell has demonstrated excellent safety behavior. Safety testing has been performed on individual cells as well as on two-cell and four-cell batteries. Single cells did not vent when short-circuited. We were able to produce benign venting in a two cell string, but only when the string was partially discharged before shorting. The vent mechanism is a 300 psi rupture pressure burst disc manufactured by BS&B Safety Systems. We define benign venting as full opening of the 3/8 in. dia vent hole without deformation of the case. Material is expelled from the cell without flame, and the cell stack remains largely intact. We have not produced venting of the Sandia-designed low rate cell under any other abuse test conditions. The vent functions as an ultimate safety mechanism in the case of severe abuse, but resistance to venting under normal use and mild abuse conditions is key to the achievement of high reliability.

    Within the nuclear industry there are two events which have had a significant impact on the way of thinking and attitudes to safety, although in different ways. The TMI accident at Harrisburg, USA put the focus on Man-Machine interface, the way of working and attitudes to safety. The accident at Chernobyl focused on Safety Management and Safety Culture. Before the TMI accident, technology was believed to be the solutions to all kinds of problems. Technical solutions should compensate for human behaviour. After the TMI accident the focus was put on Man-Machine issues and a lot of the resources within the Nuclear Industry was allocated to Man-Machine-Interfaces, Procedures, Training, etc. After the Chernobyl accident, safety culture (IAEA INSAG-4) became a commonly used concept which included an overall perspective on safety and an understanding of the interaction between Man, Technology and Organizational matters (MTO). The Safety Culture within an organization is the sum of all attitudes, qualities and experiences influencing safety. Safety Culture is consequently not only a single quality or a single property but a generic term representing the promotion of safety in many areas

    Four grid surveys were carried out in the top 200 m layer of the Lazarev Sea during fall 2004, summer 2005-06, winter 2006 and summer 2007-08 onboard the R.V. Polarstern as a part of the German SO-GLOBEC. The distribution, abundance and biology of two species of salps, Salpa thompsoni and Ihlea racovitzai, were investigated. With the exception of fall 2004, I. racovitzai dominated the salp community although being represented by low densities (<20 ind. 1000 m -3). S. thompsoni was scarce during the summers of 2005-06 and 2007-08 and almost absent from the region during winter 2006. Nevertheless, it was modestly numerous during fall 2004 reaching densities of up to 33 ind. 1000 m -3 in the south-western stations of the grid. The data on the seasonal population structure and life cycle of I. racovitzai showed that this species followed the generalized pattern typical of S. thompsoni, i.e. sexual/asexual reproduction and spawning during fall. I. racovitzai densities were the lowest during summer, increased during fall and peaked in during winter. Numerous offspring were produced by I. racovitzai during fall, just before the area became ice-covered. Conversely, S. thompsoni was not able to complete its life cycle in the Lazarev Sea, with a high occurrence of stage X (unfertilized) aggregates present. Highest S. thompsoni densities in summer and fall, and its disappearance in winter are indicative of a population of the expatriate origin that is sustained by advection.

    The jawless fish, the sea lamprey (Petromyzon marinus), spends part of its life as a burrow-dwelling, suspension-feeding larva (ammocoete) before undergoing a metamorphosis into a free swimming, parasitic juvenile that feeds on the blood of fishes. We predicted that animals in this juvenile, parasitic stage have a great capacity for catabolizing amino acids when large quantities of protein-rich blood are ingested. The sixfold to 20-fold greater ammonia excretion rates (J(Amm)) in postmetamorphic (nonfeeding) and parasitic lampreys compared with ammocoetes suggested that basal rates of amino acid catabolism increased following metamorphosis. This was likely due to a greater basal amino acid catabolizing capacity in which there was a sixfold higher hepatic glutamate dehydrogenase (GDH) activity in parasitic lampreys compared with ammocoetes. Immunoblotting also revealed that GDH quantity was 10-fold and threefold greater in parasitic lampreys than in ammocoetes and upstream migrant lampreys, respectively. Higher hepatic alanine and aspartate aminotransferase activities in the parasitic lampreys also suggested an enhanced amino acid catabolizing capacity in this life stage. In contrast to parasitic lampreys, the twofold larger free amino acid pool in the muscle of upstream migrant lampreys confirmed that this period of natural starvation is accompanied by a prominent proteolysis. Carbamoyl phosphate synthetase III was detected at low levels in the liver of parasitic and upstream migrant lampreys, but there was no evidence of extrahepatic (muscle, intestine) urea production via the ornithine urea cycle. However, detection of arginase activity and high concentrations of arginine in the liver at all life stages examined infers that arginine hydrolysis is an important source of urea. We conclude that metamorphosis is accompanied by a metabolic reorganization that increases the capacity of parasitic sea lampreys to catabolize intermittently large amino acid loads arising

    The safety of old steam boilers or hot water generators is in principle based on electromechanical components which are generally easy to understand. The use of safety-PLC is a new and flexible way to design a safe system. A programmable system offers more degrees of freedom and consequently new problems may arise. As a result, new standards which use the Safety Integrity Level (SIL) concept for the level of safety have been elaborated. The goal is to define a way of working to handle requirements on safety in control systems of heat and power plants. SIL-requirements are relatively new within the domain and there is a need for guidance to be able to follow the requirements. The target of this report is the people who work with safety questions during new construction, reconstruction, or modification of furnace plants. In the work, the Pressure Equipment Directive, 97/23/EC, as well as standards which use the SIL concept have been studied. Additionally, standards for water-tube boilers have been studied. The focus has been on the safety systems (safety functions) which are used in water-tube boilers for heat and power plants; other systems, which are parts of these boilers, have not been considered. Guidance has been given for the aforementioned standards as well as safety requirements specification and risk analysis. An old hot water generator and a relatively new steam boiler have been used as case studies. The design principles and safety functions of the furnaces have been described. During the risk analysis important hazards were identified. A method for performing a risk analysis has been described and the appropriate content of a safety requirements specification has been defined. If a heat or power plant is constructed, modified, or reconstructed, a safety life cycle shall be followed. The purpose of the safety life cycle is to plan, describe, document, perform, check, test, and validate that everything is correctly done. The components of the safety

  12. Implementation of the obligations of the joint convention on the safety of spent fuel management and on the safety of radioactive waste management. Third national report of Switzerland in accordance with Article 32 of the convention

    International Nuclear Information System (INIS)

    2008-09-01

    The report begins with a short description of Switzerland and its most important political structures. The right of referendum allows forcing a vote on changes of the constitution or against a new law. Historically, electricity generated in Switzerland came exclusively from hydropower. In the mid 1950's, interest in the nuclear energy technology was manifested to cover an increasing electricity demand. The implementation of any nuclear programme and project required a legislative frame to ensure safety and radiation protection. A corresponding article was introduced into the Federal Constitution. The Atomic Act was put into force in 1959. It attributed to the Federal Council the exclusive competence to grant licences for the construction of, operation of and modification to nuclear facilities. Licences were based on a detailed review and assessment of nuclear safety. During the 1960's, several projects for nuclear power plants (NPP) were initiated. Four of them reached the stage of realization, leading to the five currently operating units commissioned between 1969 and 1984. These five units contribute roughly 40% of the total national electricity production, the rest being essentially covered by hydro power. The increasing opposition to nuclear power during the 1970's culminated in 1990 in a double decision taken by the Swiss population: a) to accept the further operation of the existing NPPs; b) to impose a ten years moratorium on granting licences for new NPPs. In 2003 two public votes on the prolongation of the above moratorium and on the gradual phase-out of existing NPPs were rejected by the Swiss population. Simultaneously, an entirely new Nuclear Energy Act was passed by the Parliament; it came into force on 1 st February 2005 and replaced the Atomic Act. In February 2007 the Federal Council issued a new national energy strategy, including the building of new large-scale power plants and NPPs in particular. In June 2008 a general licence application was

  14. Sources of subsidence at the Salton Sea Geothermal Field

    2016-01-01

    At the Salton Sea Geothermal Field (SSGF) in Southern California, surface deformation associated with geologic processes including sediment compaction, tectonic strain, and fault slip may be augmented by energy production activities. Separating the relative contributions from natural and anthropogenic sources is especially important at the SSGF, which sits at the apex of a complex tectonic transition zone connecting the southern San Andreas Fault with the Imperial Fault; but this has been a challenging task so far. Here we analyze vertical surface velocities obtained from the persistent scatterer InSAR method and find that two of the largest subsidence anomalies can be represented by a set of volumetric strain nuclei at depths comparable to geothermal well completion zones. In contrast, the rates needed to achieve an adequate fit to the magnitudes of subsidence are almost an order of magnitude greater than rates reported for annual changes in aggregate net-production volume, suggesting that the physical mechanism responsible for subsidence at the SSGF is a complicated interplay between natural and anthropogenic sources.

    Recent events have heightened awareness of the problems raised by accidents at sea involving radioactive materials. The NEA Committee on Radiation Protection and Public Health (CRPPH) noted that, while the transport of radioactive materials at sea is governed by extensive international regulations, deficiencies remained, particularly concerning mechanisms for early accident reporting and the development of generic safety assessments and accident analysises for various kinds of sea transport. As a contribution towards improving international guidance in this field, the NEA appointed a consultant to review the current status of activities carried out by the principal international organizations concerned with the transport of radioactive materials (the IAEA, IMO and the CEC), to identify the various areas where additional work is required and to suggest appropriate improvements. Only the radiation protection aspects of sea transport have been considered here. After having examined the consultant report, the CRPPH felt that its wide distribution to national regulatory authorities in OECD countries would serve a useful purpose. The report is published under the responsibility of the Secretary-General of the OECD and does not commit Member Governments or the Organization

    This paper analyses the distinction between the status of the Vienna Convention and the status of the incorporation of the Convention's principles in national laws. Ten countries are Parties to the Vienna Convention, three others have signed it (only one of which could become a Party in the short term) and only two have established legislation. In such circumstances, and for the future, any analysis should be expanded to encompass the present and potential difficulties of the nuclear industry which has been particularly affected by the world economic and financial crisis. Also, a better understanding of the basic differences between the majority of countries which are potential parties to the Vienna Convention and the countries parties to the Paris Convention should be attained by a study on a case-by-case basis.

  18. Environmental impacts of organic and conventional agricultural products--are the differences captured by life cycle assessment?

    Comprehensive assessment tools are needed that reliably describe environmental impacts of different agricultural systems in order to develop sustainable high yielding agricultural production systems with minimal impacts on the environment. Today, Life Cycle Assessment (LCA) is increasingly used to assess and compare the environmental sustainability of agricultural products from conventional and organic agriculture. However, LCA studies comparing agricultural products from conventional and organic farming systems report a wide variation in the resource efficiency of products from these systems. The studies show that impacts per area farmed land are usually less in organic systems, but related to the quantity produced impacts are often higher. We reviewed 34 comparative LCA studies of organic and conventional agricultural products to analyze whether this result is solely due to the usually lower yields in organic systems or also due to inaccurate modeling within LCA. Comparative LCAs on agricultural products from organic and conventional farming systems often do not adequately differentiate the specific characteristics of the respective farming system in the goal and scope definition and in the inventory analysis. Further, often only a limited number of impact categories are assessed within the impact assessment not allowing for a comprehensive environmental assessment. The most critical points we identified relate to the nitrogen (N) fluxes influencing acidification, eutrophication, and global warming potential, and biodiversity. Usually, N-emissions in LCA inventories of agricultural products are based on model calculations. Modeled N-emissions often do not correspond with the actual amount of N left in the system that may result in potential emissions. Reasons for this may be that N-models are not well adapted to the mode of action of organic fertilizers and that N-emission models often are built on assumptions from conventional agriculture leading to even greater

    The safety reassessment policy implemented in France is a means of ensuring that no important point has been overlooked in the continuous safety reassessment process constituted by the integration of operating feedback. It also provides an opportunity for reappraisal of the basic design of a plant and examination of discrepancies between the safety options prevailing when it was built and those currently adopted. After a ten-year operating period, safety reassessment should enable identification of aging effects on structures and equipment, leading to improvement of component servicing and surveillance programs and provision for replacements which could be necessary

For this report, France took into account the lessons learned with the five previous reports: it is a self-standing document, which has been developed mostly on the basis of existing documents and reflects the views of the regulatory body and the licensees. Hence, for every chapter in which the regulatory body is not the only entity to express its own views, a three-fold structure was adopted: firstly a description of the regulations by the regulatory authority, followed by an overview presented by the licensees of their measures for regulatory compliance, and finally an analysis by the regulatory authority of licensee measures. This report is structured according to the Guidelines on National Reports, as revised at the special meeting of August 2012. The presentation progresses 'article by article', with each one giving rise to a separate chapter at the beginning of which the corresponding text of the Convention appears in a box with a half-tone background. After the introduction, which presents certain general aspects as well as national nuclear policy, the summary gives a description of the main changes that have taken place since the fifth national report and the safety prospects for the next three years. Part C covers general considerations (chapters 4 to 6), part D summarises general safety considerations (chapter 10 to 16), part F presents the safety of facilities (chapter 17 to 19), and finally part G presents international cooperation measures (chapter 20). The report is supplemented by eight appendices. With regard to the steps taken at the national level further to the TEPCO's Fukushima Daiichi nuclear power plant accident (hereinafter referred to as the Fukushima Daiichi accident), the Officers meeting of 29 October 2012 recommended including a general presentation in a sub-chapter of the Summary.

  4. Extreme longevity in a deep-sea vestimentiferan tubeworm and its implications for the evolution of life history strategies

    The deep sea is home to many species that have longer life spans than their shallow-water counterparts. This trend is primarily related to the decline in metabolic rates with temperature as depth increases. However, at bathyal depths, the cold-seep vestimentiferan tubeworm species Lamellibrachia luymesi and Seepiophila jonesi reach extremely old ages beyond what is predicted by the simple scaling of life span with body size and temperature. Here, we use individual-based models based on in situ growth rates to show that another species of cold-seep tubeworm found in the Gulf of Mexico, Escarpia laminata, also has an extraordinarily long life span, regularly achieving ages of 100-200 years with some individuals older than 300 years. The distribution of results from individual simulations as well as whole population simulations involving mortality and recruitment rates support these age estimates. The low 0.67% mortality rate measurements from collected populations of E. laminata are similar to mortality rates in L. luymesi and S. jonesi and play a role in evolution of the long life span of cold-seep tubeworms. These results support longevity theory, which states that in the absence of extrinsic mortality threats, natural selection will select for individuals that senesce slower and reproduce continually into their old age.

  5. The efficacy of selective calculus ablation at 400 nm: comparison to conventional calculus removal methods

    Schoenly, Joshua E.; Seka, Wolf; Romanos, Georgios; Rechmann, Peter

    A desired outcome of scaling and root planing is the complete removal of calculus and infected root tissue and preservation of healthy cementum for rapid healing of periodontal tissues. Conventional periodontal treatments for calculus removal, such as hand instrument scaling and ultrasonic scaling, often deeply scrape the surface of the underlying hard tissue and may leave behind a smear layer. Pulsed lasers emitting at violet wavelengths (specifically, 380 to 400 nm) are a potential alternative treatment since they can selectively ablate dental calculus without ablating pristine hard tissue (i.e., enamel, cementum, and dentin). In this study, light and scanning electron microscopy are used to compare and contrast the efficacy of in vitro calculus removal for several conventional periodontal treatments (hand instruments, ultrasonic scaler, and Er:YAG laser) to calculus removal with a frequency-doubled Ti:sapphire (λ = 400 nm). After calculus removal, enamel and cementum surfaces are investigated for calculus debris and damage to the underlying hard tissue surface. Compared to the smear layer, grooves, and unintentional hard tissue removal typically found using these conventional treatments, calculus removal using the 400-nm laser is complete and selective without any removal of pristine dental hard tissue. Based on these results, selective ablation from the 400-nm laser appears to produce a root surface that would be more suitable for successful healing of periodontal tissues.

  6. Emerging Methods and Systems for Observing Life in the Sea

    There is a growing need for observations of life in the sea at time and space scales consistent with those made for physical and chemical parameters. International programs such as the Global Ocean Observing System (GOOS) and Marine Biodiversity Observation Networks (MBON) are making the case for expanded biological observations and working diligently to prioritize essential variables. Here we review past, present and emerging systems and methods for observing life in the sea from the perspective of maintaining continuous observations over long time periods. Methods that rely on ships with instrumentation and over-the-side sample collections will need to be supplemented and eventually replaced with those based from autonomous platforms. Ship-based optical and acoustic instruments are being reduced in size and power for deployment on moorings and autonomous vehicles. In parallel a new generation of low power, improved resolution sensors are being developed. Animal bio-logging is evolving with new, smaller and more sophisticated tags being developed. New genomic methods, capable of assessing multiple trophic levels from a single water sample, are emerging. Autonomous devices for genomic sample collection are being miniaturized and adapted to autonomous vehicles. The required processing schemes and methods for these emerging data collections are being developed in parallel with the instrumentation. An evolving challenge will be the integration of information from these disparate methods given that each provides their own unique view of life in the sea.

The Contracting Parties highlighted areas of focus to be brought back to the fourth review meeting and also committed to a continuity process to revitalize the review processes under the CNS. Specific progress has been achieved in the first year since the conclusion of the third review meeting, but further commitment to progress is required, by the Contracting Parties and the Secretariat of the IAEA, over the next year, especially if changes to the review processes are to be achieved for the fourth review meeting in 2008.

    Waste Management, to which France is a Contracting Party, an account was made of the measures taken in those respective fields with regard to research reactors. Lastly, the Board of Governors of the International Atomic Energy Agency (IAEA), of which France is a member, approved in March 2004 the Code of Conduct on the Safety of Research Reactors, which reiterates most of the provisions of the Convention. This report was produced by ASN, the French nuclear safety authority, which coordinated the work on it, with contributions from IRSN (Institute for Radiation Protection and Nuclear Safety) and from nuclear reactor licensees, Electricite de France (EDF), the Atomic Energy Commission (CEA) which became the French Atomic and Alternative Energies Commission on 10 March 2010 and the Laue-Langevin institute (ILL). The final version was completed in July 2010 after consultation with the French parties concerned. For this report, France took into account the lessons learnt with the four previous reports and is presenting a self-standing document, which has been developed mostly on the basis of existing documents and reflecting the views of the different stakeholders, including the regulatory body and the various operators. Hence, for every chapter in which the regulatory authority is not the only entity to express its own views, a three-fold structure was adopted, starting with a description of the regulations by the regulatory authority, followed by an overview presented by the operators of their measures for complying with regulations, and ending with an analysis of operator measures by regulatory bodies.

    Methane seep in deep sea environment could lead to build up of chemosynthesis communities, and a number of geological and biological anomalies as compare to the surrounding area. In order to examine the linkage between seep anomalies and those at the vicinity background area, and to detail mapping those spatial variations, we used a deep towed camera system (TowCam) to survey seafloor on the Tainan Ridge, Northeastern South China Sea (SCS). The underwater sea floor pictures could provide better spatial variations to demonstrate impact of methane seep on the sea floor. Water column variations of salinity, temperature, dissolved oxygen were applied to delineate fine scale variations at the study area. In addition, sediment cores were collected for chemical analyses to confirm the existence of local spatial variations. Our results show large spatial variations existed as a result of differences in methane flux. In fact, methane is the driving force for the observed biogeochemical variations in the water column, on the sea floor, and in the sediment. Of the area we have surveyed, there are approximately 7% of total towcam survey data showing abnormal water properties. Corresponding to the water column anomalies, underwater sea floor pictures taken from those places showed that chemosynthetic clams and muscles could be identified, together with authigenic carbonate buildups, and bacterial mats. Moreover, sediment cores with chemical anomalies also matched those in the water column and on the sea floor. These anomalies, however, represent only a small portion of the area surveyed and could not be identified with typical (random) coring method. Methane seep, therefore, require tedious and multiple types of surveys to better understand the scale and magnitude of seep and biogeochemical anomalies those were driven by gas migrations.

    The aim of this work is to evaluate the activity of allyl isothiocyanate (AITC) against fish spoilage bacteria (specific spoilage organisms; SSOs) as well as its possible use in gilthead sea bream ( Sparus aurata ) fillets to extend their shelf-life. In this regard, in vitro tests are carried out in order to evaluate the inhibitory activity of AITC and its vapours on several strains of SSOs. The AITC effect on the shelf-life of sea bream fillets was made by putting them in plastic trays hermetically closed with the addition AITC. Microbiological and sensorial evaluations were made on fish fillets during storage. Treated fillets maintained microbial populations at a significantly lower level compared with the control samples during storage, showing better sensorial characteristics. Therefore, the use of AITC's vapours seems to be a new and interesting alternative way to increase fish product shelf-life.

  12. Participatory Design of Multi-Use Platforms at Sea

    2016-01-01

    Full Text Available European oceans are subject to rapid development. New activities such as aquaculture and ocean energy have gained importance. This triggers interest in “multi-use platforms at sea” (MUPS, i.e., areas at sea in which different activities are combined. MUPS are complex features with regards to technology, governance, and financial, socioeconomic, and environmental aspects. To identify realistic and sustainable solutions and designs for MUPS, the MERMAID project applied a participatory design process (PDP involving a range of stakeholders representing companies, authorities, researchers, and NGOs. This paper evaluates if and how the participatory design process contributed to the design of multi-use platforms. It is based on interviews with the managers of the case study sites and a questionnaire administered to all stakeholders participating in the PDP workshops. Analyzing the four case studies, we conclude that the participatory design process has had a valuable contribution to the development of the four different designs of MUPS, even though the preconditions for carrying out a participatory design process differed between sites. In all four cases, the process has been beneficial in generating new and shared knowledge. It brought new design issues to the table and increased knowledge and understanding among the different stakeholders.

    The guidelines presented in Design Evaluation guidelines for Department of Energy Facilities Subjected to natural Phenomena Hazards (UCRL 15910 Draft; May 1989) include evaluation criteria for existing Department of Energy buildings subjected to earthquakes. These criteria were developed at the Lawrence Livermore National Laboratory for use in both the seismic design of new structures and the evaluation of existing structures. ATC-14: Evaluating The Seismic Resistance of Existing Buildings developed by the Applied Technology Council, consists of guidelines and criteria for identifying the buildings or building components that present unacceptable risk to human lives. This paper compares and contrasts the two evaluation guidelines for existing buildings using a prototype building as an example. The prototype building is a seven story, concrete shear wall building assuming a General Use Occupancy

  14. Promotion of good safety culture at a Canadian HWR

    International Nuclear Information System (INIS)

    Curle, B.

    1996-01-01

    People work at a nuclear plant within a structured environment. It is the programs, procedures and other ''tools'' that are used in the workplace that actually guide behaviours, and behaviours then guide performance. The safety culture in the workplace is ''the way we do things around here''. This culture is created by structures, behaviours and performance, and is characterized by three attributes: A questioning attitude; a rigorous and prudent approach; open 2-way communication. This paper discusses a model of safety culture which puts the operating experience or learning cycle program at the heart of the endeavor. This cycle also consists of three elements: Observation; reporting; learning. It is more of a theoretical paper than a report of success at this stage. However, the ideas presented are being used to design and implement a strong safety culture at Ontario Hydro's Darlington Nuclear Station (4 x 932 Mwe CANDU units), and are beginning to show results. Programs designed for excellence in human performance have to provide clear simple structure, and draw people into alignment with the required behaviours. By making the structural elements and the alignment activities explicit an attempt can be made to ''design'' programs that will create and reinforce the required safety culture. The paper places the learning cycle at the heart of safety culture because the cycle aligns with the three attributes of safety culture. If an organization cannot learn from experience (i.e. change behaviours based on experience) it is doubtful whether it can build a strong safety culture. 2 refs

    International Nuclear Information System (INIS)

    2014-01-01

    The report begins with a presentation of Switzerland and its political system which is partitioned between the Federal Council, the 26 cantons with their own governments, and the municipalities. Total energy consumption in Switzerland was 896,000 TJ in 2013, electricity accounting for about 24% with 36% of this from nuclear power. Until the late 1960s, Switzerland generated electricity exclusively from hydro power. By the mid-1950s, the private sector increased its interest in nuclear energy technology. The nuclear programme required a legislative framework to ensure safety and radiation protection: the Atomic Energy Act came into force in 1959.

    The report begins with a presentation of Switzerland and its political system which is partitioned between the Federal Council, the 26 cantons with their own governments, and the municipalities. Total energy consumption in Switzerland was 896,000 TJ in 2013, electricity accounting for about 24% with 36% of this from nuclear power. Until the late 1960s, Switzerland generated electricity exclusively from hydro power. By the mid-1950s, the private sector increased its interest in nuclear energy technology. The nuclear programme required a legislative framework to ensure safety and radiation protection: the Atomic Energy Act came into force in 1959. In 2005, Switzerland enacted a new Nuclear Energy Act according to which decisions on general licences for new nuclear facilities are subject to a facultative national referendum. The Federal Government was given full legal responsibility for licensing geological waste repositories. The first experimental nuclear reactor started operation in 1957.

    Full Text Available The very thin sea surface nanolayer on top of the sea surface microlayer, sometimes just one monomolecular layer thick, forms the interface between ocean and atmosphere. Due to the small dimension and tiny amount of substance, knowledge about the development of the layer in the course of the year is scarce. In this work, the sea surface nanolayer at Boknis Eck Time Series Station (BE, southwestern Baltic Sea, has been investigated over a period of three and a half years. Surface water samples were taken monthly by screen sampling and were analyzed in terms of organic content and composition by sum frequency generation spectroscopy, which is specifically sensitive to interfacial layers. A yearly periodicity has been observed with a pronounced abundance of sea surface nanolayer material (such as carbohydrate-rich material during the summer months. On the basis of our results we conclude that the abundance of organic material in the nanolayer at Boknis Eck is not directly related to phytoplankton abundance alone. We speculate that indeed sloppy feeding of zooplankton together with photochemical and/or microbial processing of organic precursor compounds is responsible for the pronounced seasonality.

    Full Text Available Starting with 2008 and till 2013 there have been alarm messages about fires occurring at landfill places in Russia. Landfill fires are especially dangerous as they emit dangerous fumes from the combustion of the wide range of materials within the landfill. Subsurface landfill fires, unlike typical fires, cannot be put out with water. The article includes the analysis of the sources and causes of conflagrations at landfills. There maintains the necessity to eliminate the reasons, which cause the fires. There are quantification indices of environmental, social and economic effects of fires at landfills all over Russia. Surface fires generally burn at relatively low temperatures and are characterized by the emission of dense white smoke and the products of incomplete combustion. The smoke includes irritating agents, such as organic acids and other compounds. Higher temperature fires can cause the breakdown of volatile compounds, which emit dense black smoke. Surface fires are classified as either accidental or deliberate. For the ecologic security there is a need in the execution of proper hygienic requirements to the content of the places as well as international recommendations. In addition to the burning and explosion hazards posed by landfill fires, smoke and other by-products of landfill fires also present a health risk to firefighters and others exposed to them. Smoke from landfill fires generally contains particulate matter (the products of incomplete combustion of the fuel source, which can aggravate pre-existing pulmonary conditions or cause respiratory distress and damage ecosystem. The monitoring of conducting preventive inflamings and transition to alternative, environment friendly methods of waste disposal is needed.

  1. Effect of freezing rate and storage time on shelf-life quality of hot boned and conventionally boned ground beef

    1986-01-01

    Commercially processed, 80% lean, chub packaged ground beef (both conventionally boned and hot boned) was frozen to O F (-18 0 C) at three rates: 72, 96, and 120 hours before storage at O F (-18 0 C). The meat was examined after 0, 1.5, 3, 6, 9, and 12 months storage for the following attributes: psychrophile and aerobic plate counts, free fatty acid (FFA) and thiobarbituric acid (TBA) values, niacin content, raw and cooked color, moisture, fat and protein contents, and cook shrink and texture of cooked patties. Freezing rates had no significant effect on microbial load, niacin content, color, or cook shrink and texture. Freezing rate had a significant effect upon TBA and FFA values. Niacin, cook shrink and moisture values declined and TBA and FFA values increased with storage. Raw meat Hunter L value increased and Hunter a/b value declined during storage. Substantial quality differences between meat types were found

    2008-09-15

    The report begins with a short description of Switzerland and its most important political structures. The right of referendum allows forcing a vote on changes of the constitution or against a new law. Historically, electricity generated in Switzerland came exclusively from hydropower. In the mid 1950's, interest in the nuclear energy technology was manifested to cover an increasing electricity demand. The implementation of any nuclear programme and project required a legislative frame to ensure safety and radiation protection. A corresponding article was introduced into the Federal Constitution. The Atomic Act was put into force in 1959. It attributed to the Federal Council the exclusive competence to grant licences for the construction of, operation of and modification to nuclear facilities. Licences were based on a detailed review and assessment of nuclear safety. During the 1960's, several projects for nuclear power plants (NPP) were initiated. Four of them reached the stage of realization, leading to the five currently operating units commissioned between 1969 and 1984. These five units contribute roughly 40% of the total national electricity production, the rest being essentially covered by hydro power. The increasing opposition to nuclear power during the 1970's culminated in 1990 in a double decision taken by the Swiss population: a) to accept the further operation of the existing NPPs; b) to impose a ten years moratorium on granting licences for new NPPs. In 2003 two public votes on the prolongation of the above moratorium and on the gradual phase-out of existing NPPs were rejected by the Swiss population. Simultaneously, an entirely new Nuclear Energy Act was passed by the Parliament; it came into force on 1{sup st} February 2005 and replaced the Atomic Act. In February 2007 the Federal Council issued a new national energy strategy, including the building of new large-scale power plants and NPPs in particular. In June 2008 a general licence

    The knowledge of the optical contrast of an oil layer on the sea under various surface roughness conditions is of great interest for oil slick monitoring techniques. This paper presents a 3D simulation of a dynamic sea surface contaminated by a floating oil film. The simulation considers the damping influence of oil on the ocean waves and its physical properties. It calculates the radiance contrast of the sea surface polluted by the oil film in relation to a clean sea surface for the SWIR spectral band. Our computer simulation combines the 3D simulation of a maritime scene (open clear sea/clear sky) with an oil film at the sea surface. The basic geometry of a clean sea surface is modeled by a composition of smooth wind driven gravity waves. Oil on the sea surface attenuates the capillary and short gravity waves modulating the wave power density spectrum of these waves. The radiance of the maritime scene is calculated in the SWIR spectral band with the emitted sea surface radiance and the specularly reflected sky radiance as components. Wave hiding and shadowing, especially occurring at low viewing angles, are considered. The specular reflection of the sky radiance at the clean sea surface is modeled by an analytical statistical bidirectional reflectance distribution function (BRDF) of the sea surface. For oil at the sea surface, a specific BRDF is used influenced by the reduced surface roughness, i.e., the modulated wave density spectrum. The radiance contrast of an oil film in relation to the clean sea surface is calculated for different viewing angles, wind speeds, and oil types characterized by their specific physical properties.

    1999-01-01

    The SINTEF Oil Weathering Model (OWM) has been extensively tested with results from full-scale field trials with experimental oil slicks in the Norwegian NOFO Sea trials in 1994 and 1995 and the AEA 1997 trials in UK. The comparisons between oil weathering values predicted by the model and ground-truth obtained from the field trials are presented and discussed. Good laboratory weathering data of the specific oil as input to the model is essential for obtaining reliable weathering predictions. Predications provided by the SINTEF-OWM enable oil spill personnel to estimate the most appropriate 'window of opportunity' for use of chemical dispersants under various spill situations. Pre-spill scenario analysis with the SINTEF Oil Spill Contingency and Response (OSCAR) model system, in which the SINTEF-OWM is one of several components, has become an important part of contingency plans as well as contingency training of oil spill personnel at refineries, oil terminals and offshore installations in Norway.

    1984-01-01

    The Department of Energy (DOE) Albuquerque Operations Office is responsible for the safety overview of nuclear reactor and critical assembly facilities at Sandia National Laboratories, Los Alamos National Laboratory, and the Rocky Flats Plant. The important safety concerns with these facilities involve the complex experiments that are performed, and that is the area emphasized. A determination is made by the Albuquerque Office (AL) with assistance from DOE/OMA whether or not a proposed experiment is an unreviewed safety question. Meetings are held with the contractor to resolve and clarify questions that are generated during the review of the proposed experiment. The AL safety evaluation report is completed and any recommendations are discussed. Prior to the experiment a preoperational appraisal is performed to assure that personnel, procedures, and equipment are in readiness for operations. During the experiment, any abnormal condition is reviewed in detail to determine any safety concerns

  7. Status of safety issues at licensed power plants

    International Nuclear Information System (INIS)

    1991-05-01

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, a program has been established whereby an annual NUREG report will be published on the status of licensee implementation and NRC verification of safety issues in major NRC requirement areas. This report, the second volume of a three-volume series, addresses the status of unresolved safety issues (USIs) at licensed plants. The data contained in these NUREG reports are a product of the NRC's Safety Issues Management System (SIMS) database, which is maintained by the Project Management Staff in the Office of Nuclear Reactor Regulation and by NRC regional personnel. The purpose of this report is to provide a comprehensive description of the status of implementation and verification of the 27 safety issues designated as USIs and to make this information available to other interested parties, including the public. A corollary purpose of this NUREG report is to serve as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues up until requirements are approved for imposition at licensed plants. 3 figs., 4 tabs

    stipulations of the present Convention. This report was produced by ASN, the French nuclear safety authority, which coordinated the work on it, with contributions from IRSN (Institute for Radiation Protection and Nuclear Safety) and from nuclear reactor licensees, Electricite de France (EDF), the Atomic Energy Commission (CEA) and the Laue-Langevin institute (ILL). The final version was completed in July 2007 after consultation with the French parties concerned. For this report, France has taken account of the experience acquired with the three previous editions: it is a stand-alone report based mainly on existing documents and reflecting the viewpoints of the various stakeholders (regulatory authority and licensees). Thus, for each of the chapters in which the regulatory authority is not the only party to express its point of view, a three-part structure has been adopted: first a description of the regulations by the regulatory authority, followed by a presentation by the licensees of the steps taken to comply with the regulations, and finally an analysis by the regulatory authority of the steps taken by the licensees. The report is structured according to the guidelines for national reports, as modified during the 2002 peer review meeting. The presentation is made 'article by article', each being the subject of a separate chapter, at the beginning of which the corresponding text of the Convention article is reproduced in a shadow box. This introduction presents the main changes since the third national report and France's nuclear power policy. Part A deals with the general provisions (articles 4 to 6). Part B summarises the legislation and regulations (articles 7 to 9). Part C is devoted to general safety considerations (articles 10 to 16). Part D discusses the safety of the installations (articles 17 to 19). The conclusion outlines future trends in the field of nuclear safety in France, including measures for international cooperation. The report is supplemented by a number

  9. Safety Oversight of Decommissioning Activities at DOE Nuclear Sites

    The Defense Nuclear Facilities Safety Board (Board) is an independent federal agency established by Congress in 1988 to provide nuclear safety oversight of activities at U.S. Department of Energy (DOE) defense nuclear facilities. The activities under the Board's jurisdiction include the design, construction, startup, operation, and decommissioning of defense nuclear facilities at DOE sites. This paper reviews the Board's safety oversight of decommissioning activities at DOE sites, identifies the safety problems observed, and discusses Board initiatives to improve the safety of decommissioning activities at DOE sites. The decommissioning of former defense nuclear facilities has reduced the risk of radioactive material contamination and exposure to the public and site workers. In general, efforts to perform decommissioning work at DOE defense nuclear sites have been successful, and contractors performing decommissioning work have a good safety record. Decommissioning activities have recently been completed at sites identified for closure, including the Rocky Flats Environmental Technology Site, the Fernald Closure Project, and the Miamisburg Closure Project (the Mound site). The Rocky Flats and Fernald sites, which produced plutonium parts and uranium materials for defense needs (respectively), have been turned into wildlife refuges. The Mound site, which performed R and D activities on nuclear materials, has been converted into an industrial and technology park called the Mound Advanced Technology Center. The DOE Office of Legacy Management is responsible for the long term stewardship of these former EM sites. The Board has reviewed many decommissioning activities, and noted that there are valuable lessons learned that can benefit both DOE and the contractor. As part of its ongoing safety oversight responsibilities, the Board and its staff will continue to review the safety of DOE and contractor decommissioning activities at DOE defense nuclear sites

    The sea urchin Sphaerechinus granularis was used to investigate the impact of relevant levels of UV-B radiation on the early life stages of a common Mediterranean free spawning benthic species. Sperm, eggs and embryos were exposed to a range of UV radiation doses. The resulting endpoints were evaluated in terms of fertilisation success, development and survival rates. Above a weighted UV radiation dose of 0.0029 kJ m{sup -2}, fertilisation capability of irradiated sperm decreased rapidly. The exposure of the eggs to 0.0175 kJ m{sup -2} and more led to delayed and inhibited development with ensuing embryonic morphological abnormalities. One-day old larvae remained strongly sensitive to UV radiation as shown by the 50% decrease of the larval survival rate for a dose of 0.025 kJ m{sup -2} UVR. The elevated sensitivity of embryos to experimental UVR went along with a lack of significant amount of sunscreen compounds (e.g., mycosporine-like amino acids) in the eggs. The present results demonstrated that gamete viability and embryonic development may be significantly impaired by solar UV radiation in S. granularis, compromising in this way the reproduction of the species. Unless adaptive behavioural reproductive strategies exist, the influence of ambient UV radiation appears as a selective force for population dynamics of broadcast spawners in the shallow benthic Mediterranean environment.

    R(+)limonene (LMN) is the major aromatic compound in essential oils obtained from oranges, grapefruits, and lemons. The improvement of preservation techniques to reduce the growth and activity of spoilage microorganisms in foods is crucial to increase their shelf life and to reduce the losses due to spoilage. The aim of this work is to evaluate the effect of LMN on the shelf life of fish fillets. Its effectiveness was preliminarily investigated in vitro against 60 strains of Specific Spoilage Organisms (SSOs) and then on gilt-head sea bream fillets stored at 2±0.5°C for 15days under vacuum. LMN showed a good inhibitory effect against tested SSOs strains. On gilt-head sea bream fillets, LMN inhibited the growth SSOs effectively, and its use resulted in a shelf-life extension of ca. 6-9days of treated fillets, compared to the control samples. The LMN addition in Sparus aurata fillets giving a distinctive smell and like-lemon taste to fish fillets that resulted pleasant to panellists. Its use contributed to a considerable reduction of fish spoilage given that the fillets treated with LMN were still sensory acceptable after 15days of storage. LMN may be used as an effective antimicrobial system to reduce the microbial growth and to improve the shelf life of fresh gilt-head sea bream fillets. Copyright © 2016 Elsevier B.V.

    The present study aims at evaluating the potential environmental impact of using recycled high-density polyethylene (HDPE) in the production of an anti-glare lamella (AGL), a road safety device currently manufactured from virgin (not recycled) polymer. The impact was evaluated using the life cycle assessment (LCA) technique and comparing two alternative systems: current AGL, manufactured from virgin HDPE, and optional AGL, made with recycled HDPE obtained from post-consumer packages. The AGL manufacturing phase was found to be responsible for most of the impacts in both systems, with the production of the raw material being the largest contributor for that phase. The present study makes a contribution to the problem of developing value-added products made from post-consumer polymeric recyclates.

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, a program has been established whereby an annual NUREG report will be published on the status of licensee implementation and NRC verification of safety issues in major NRC requirement areas. This report, the third volume of a three-volume series, addresses the status of generic safety issues (GSIs) at licensed plants. Volume 1 addressed the status of Three Mile Island Action Plan requirements and was published in March 1991. Volume 2 addressed the status of implementation and verification of unresolved safety issues and was published in May 1991. The annual NUREG report will combine these three areas in a single volume to be published in late 1991. The data contained in these NUREG reports are a product of the NRC's Safety Issues Management System (SIMS) database, which is maintained by the Project Management Staff in the Office of Nuclear Reactor Regulation and by NRC regional personnel. The purpose of this report is to provide a comprehensive description of the status of implementation and verification of the 34 GSIs and sub-issues that have been resolved by the NRC and involve implementation of an action or actions by licensees. This NUREG report also serves as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues up until a request for action by licensees is issued by NRC. 3 figs., 6 tabs

  18. Articulating the differences between safety and resilience: the decision-making process of professional sea-fishing skippers.

    2008-02-01

    As the world's most dangerous profession, sea fishing enables discussion of the concept of resilience and its articulation to the notion of safety in complex systems. In the small, emerging community working on this concept, the prevailing idea to improve safety is that resilience must be reinjected into the know-how of complex systems. Thirty-four male skippers, divided into two groups, took part in an interactive simulation of a fishing campaign. They had to make decisions in situations of trade-off between safety and production goals. From the time they left the harbor, the fishermen never gave up on fishing, even in extreme conditions, and regardless of whether or not the catch was good. Not being suicidal, however, they used multiple expert strategies to reduce risk without giving up on their fishing activity. Systems run by craftspeople are very resilient because they rely on a high level of adaptability, based on the actors' expertise, linked to an exposure to frequent and considerable risk. Each actor is responsible for his or her own safety. The final discussion bears on the question of knowing whether or not it is possible to design a safe system while preserving its craftsmanship and therefore its native resilience. The results of these studies suggest potential adverse effects of classic safety interventions in complex sociotechnical systems either in terms of professional reluctance to accept new recommendations or through the emergence of new sources of risk.

    E-cigarette (vaping) conventions are public events promoting electronic cigarettes, in which indoor use of e-cigarettes is allowed. The large concentration of people using e-cigarettes and poor air ventilation can result in indoor air pollution. In order to estimate this worst-case exposure to e-cigarettes, we evaluated indoor air quality in a vaping convention in Maryland (MD), USA. Real-time concentrations of particulate matter (PM 10 ) and real-time total volatile organic compounds (TVOCs), CO 2 and NO 2 concentrations were measured. Integrated samples of air nicotine and PM 10 concentrations were also collected. The number of attendees was estimated to range from 75 to 600 at any single observation time. The estimated 24-h time-weighted average (TWA) PM 10 was 1800 μg/m 3 , 12-fold higher than the EPA 24-h regulation (150 μg/m 3 ). Median (range) indoor TVOCs concentration was 0.13 (0.04-0.3) ppm. PM 10 and TVOC concentrations were highly correlated with CO 2 concentrations, indicating the high number of people using e-cigarettes and poor indoor air quality. Air nicotine concentration was 125 μg/m 3 , equivalent to concentrations measured in bars and nightclubs. E-cigarette aerosol in a vaping convention that congregates many e-cigarette users is a major source of PM 10 , air nicotine and VOCs, impairing indoor air quality. These findings also raise occupational concerns for e-cigarette vendors and other venue staff workers.

    Within the last 12 years a number of regional pollution conventions and action plans have been negotiated to protect the world's seas from pollution. This paper traces the development of this activity and points out the specific role of regional, as opposed to global, pollution conventions. Chief among the functions of regional conventions is the specific legal framework they provide for a particular geographical region. They also provide a forum for neighboring states to develop a coherent policy for a particular regional sea, as well as being the means of establishing regional control over potentially polluting activities. Regional agreements also constitute a suitable framework for monitoring the input of pollutants to the marine environment and assessing their effects. In addition, they provide a forum for the exchange of scientific and technical information and for developing cooperation between states. The paper concludes by summarizing the most important functions of a regional convention and suggesting that, with increasing industrialization and pollution stress, there will continue to be a need for action to be taken at the regional level

    In the literature it is shown that aquatic organisms are very sensitive to changes in the pH value. Exposure to a lower pH value than what is normal for the animals, may lead to distinct effects in the reproduction, growth and survival. Harmful effects may arise by a reduction of only 0.2 pH units. The effects increase by increasing the pH reduction, and by increasing the exposure time. It is pointed out in the report that the data basis is small, and that only a few long term and life cycle studies have been performed. The background material of the report shows that injection of CO 2 into the sea will create a bottom stream with pH values between 4.5 and 6.5. These values are much lower than the normal pH value of seawater, and much lower than the limit value for harmful effects. For this reason, harmful effects on the bottom fauna may be expected. 57 refs., 3 figs., 2 tabs

    To evaluate changes in the general and oral health-related quality of life (using the European Quality of Life indicator and the Oral Health Impact Profile-49 [OHIP-49], respectively) of patients treated with conventionally or immediately loaded implants. This clinical trial consisted of a clinical oral examination and a questionnaire-based interview carried out before and after both surgery and definitive prosthetic rehabilitation in a consecutive sample of patients requiring dental implants. According to the clinical diagnosis and patient preference, patients were assigned to the immediate loading group (IL group; n = 29) or the conventional loading group (CL group; n = 75). The change summary scores and effect sizes were calculated in the intermediate stage and at the final follow-up, taking baseline scores as reference. The oral health-related quality of life and oral satisfaction after implant therapy were significantly better than at baseline, with an even greater benefit when the implants were loaded immediately than when prosthetic rehabilitation was delayed. However, there were no significant differences in between-group comparisons in the ratings of general health status. The effect size for the OHIP-49 exceeded the threshold value of 0.8 for the domains functional limitation, pain/discomfort, and psychological discomfort in both groups and also for physical disability and psychological disability in the IL group. A gradual improvement in oral well-being scores, but not in those of general well-being, were observed for both groups from the intermediate stage to the final evaluation. This benefit was markedly greater for the IL group.

    Full Text Available Objective: To explore the efficacy and safety of conventional radiotherapy of chest wall and clavicular field and three-dimensional conformal radiotherapy in patients after modified radical mastectomy. Methods: A total of 84 patients who were admitted in our hospital after modified radical mastectomy were included in the study and divided into the conventional radiotherapy group (n=42 and the three-dimensional conformal radiotherapy group (n=42 according to different radiotherapy methods. The patients in the conventional radiotherapy group were given conventional radiotherapy of chest wall and clavicular field, while the patients in the three-dimensional conformal radiotherapy group were given three-dimensional conformal radiotherapy. The serum tumor markers and peripheral blood T lymphocyte subsets 6-8 weeks after treatment in the two groups were detected. The clinical efficacy, and toxic and side effects in the two groups were evaluated. Results: The serum CA15-3, CA125, CEA, and CK19 levels after treatment in the two groups were significantly reduced when compared with before treatment, CD3 +,CD4 +, and CD4 +/CD8 + were significantly elevated, while CD8 + was significantly reduced when compared with before treatment, but the comparison of the above indicators between the two groups was not statistically significant. The occurrence rate of radioactive skin damage and pneumonia after treatment in the conventional radiotherapy group was significantly higher than that in the three-dimensional conformal radiotherapy group. Conclusions: The two kinds of radiotherapy schemes have an equal efficacy, but the toxic and side effects of three-dimensional conformal radiotherapy are significantly lower than those by the conventional radiotherapy, with a certain advantage.

    This paper gives an outline of the development and use of STUK's indicator system at the department of Nuclear Reactor Regulation (YTO) in the Radiation and Nuclear Safety Authority, STUK. Indicators used at YTO are measures related to the safety of nuclear installations and regulatory activities. Indicators are numbers, ratios, percentages and amounts of interested matters that are for suitable for regulatory purposes, that is assessment and trending of the safety of nuclear installations and regulatory activities. STUK's indicator system is divided into two main areas: safety of nuclear facilities and regulatory activities. Safety of nuclear facilities is divided into 3 areas based on the concept of defence in de safety and quality culture, operational events and physical barriers. Regulatory activities are divided into 3 areas: working processes, resource management and regeneration and ability to work. These areas are measured using several indicators. At the moment some of indicators are included in YTO's management system to measure whether or not internally set goals are achieved. (author)

    We report on results of the Research Training Group Baltic TRANSCOAST. The overall aim of Baltic TRANSCOAST is to enhance our knowledge of the shallow coast ecocline. How is the marine coastal zone influenced by terrestrial processes? How is the terrestrial coastal zone influenced by marine processes? These questions lead our research within the three research fields covering hydro-dynamic, (bio)geochemical and biological processes. Regarding the hydro-dynamics we assess how the peatland's water balance, the current dynamics and hydraulic properties of the marine sediments and the subsoil influence sea water intrusions into the peatland and/or submarine groundwater discharge into the Baltic Sea. With respect to (bio)geochemical processes we address how (bio)geochemical transformation processes both in the marine and the terrestrial part of the coast are influenced by water and matter inputs from the respective other coastal domain. Finally, reagrding the biological processes, we are interested in revealing how the primary production and the composition of the micro- and macro-phytobenthos in the shallow Baltic Sea influence matter transformation processes. The integrative approach of Baltic TRANSCOAST allows us to get to grips with questions that are otherwise hard to tackle. For instance, we address how the pore water constituents drive microbial processes and the deposition of nutrients and and how they are impacted by sediment resuspension and translocation. We investigate how the hydrology of the peat layers interferes with the generation of trace gases and investigate the role of the nearby Warnow river and its plume and how this changes under the impact of wind direction and wind strength. For the latter we rely on data and models. Further, as a common basis for all topics addressed in Baltic TRANSCOAST we established the geology of the study area and learned that regional variability may play a major role in shaping the processes under study.

  9. Status of safety issues at licensed power plants: TMI action plan requirements, unresolved safety issues, generic safety issues

    International Nuclear Information System (INIS)

    1991-12-01

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, a program was established whereby an annual NUREG report would be published on the status of licensee implementation and NRC verification of safety issues in major NRC requirements areas. This information was compiled and reported in three NUREG volumes. Volume 1, published in March 1991, addressed the status of of Three Mile Island (TMI) Action Plan Requirements. Volume 2, published in May 1991, addressed the status of unresolved safety issues (USIs). Volume 3, published in June 1991, addressed the implementation and verification status of generic safety issues (GSIs). This annual NUREG report combines these volumes into a single report and provides updated information as of September 30, 1991. The data contained in these NUREG reports are a product of the NRC's Safety Issues Management System (SIMS) database, which is maintained by the Project Management Staff in the Office of Nuclear Reactor Regulation and by NRC regional personnel. This report is to provide a comprehensive description of the implementation and verification status of TMI Action Plan Requirements, safety issues designated as USIs, and GSIs that have been resolved and involve implementation of an action or actions by licensees. This report makes the information available to other interested parties, including the public. An additional purpose of this NUREG report is to serve as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues up until requirements are approved for imposition at licensed plants or until the NRC issues a request for action by licensees

    No previous studies have reported the longitudinal health-related quality of life (HRQOL) for intensity modulated radiation therapy (IMRT). We compared HRQOL after IMRT with that after conventional and after conformal radiation therapy (XRT). A total of 110 patients underwent XRT (34 patients underwent conventional radiation therapy and 76 underwent conformal radiation therapy) and 30 underwent IMRT for clinically localized prostate cancer between 2000 and 2002. We measured the general and disease-specific HRQOL using the Medical Outcomes Study 36-Item Health Survey and University of California, Los Angeles, Prostate Cancer Index, respectively. There were no significant differences in the preoperative characteristics and HRQOL scores of the two groups. Repeated measure analyses of variance revealed significantly different patterns of alteration in several general HRQOL domains between XRT and the IMRT groups. In the urinary domain, there was no difference in the alteration patterns between the two groups. The XRT group suffered worse bowel function at 3 and 6 months than the IMRT group (P<0.05). In the XRT group, sexual function decreased at 3 months and remained substantially lower than the baseline level. However, the IMRT group showed no significant difference from the baseline level at any of the observation periods. At 18 months the XRT group showed worse sexual function than the IMRT group. The two approaches showed different longitudinal profiles regarding general and disease-specific HRQOL during the first 2 years after treatment. The IMRT approach produced little impairment in bowel and sexual function. (author)

There they already have blooming and fruiting self-seeds. Chinese tulip poplar sometimes reaches here bigger sizes than in natural habitat. It resists winter temperatures very well. Both species can be jointly used along the Caucasian Black Sea coast as ornamental trees because there are the most favorable conditions for their vegetation. Due the great resistance American tulip trees can grow along the coastline as well as inland of Ajara.

    Wind energy use experienced an enormous upswing in recent years. In the meantime a wind energy capacity of more than 26,000 MW has been installed worldwide and this positive development appears to continue at the same pace. According to a study of the renowned consulting company BTM Consult an additional capacity of 54,000 MW will be installed in the next five years. Apart from the development in the onshore area and the gained experience, the large-scale technical utilisation of wind power at sea in Europe becomes more and more the focus of attention. The planned wind power plants are supposed to have a capacity between three and five MW and the number of plants in the final extension phase is supposed to amount to 200 plants, which corresponds to an installed capacity of up to 1,000 MW per park. Plans are partly made for plants located between 30 and 40 kilometres from the coast and in water depths of up to 35 meters. Research results about the wind conditions and the location requirements at these distances from the coast are only available to a certain extent. In order to obtain reliable data several research projects have been initiated. In this study you will not only find contributions to the subjects mentioned above but also reports from experts, who explain their knowledge and experience gained from practice. (orig.)

    The microbiological quality of meat luncheon sold in retail market at Cairo was evaluated E. coli was found in all tested samples (25 samples), Staphylococcus aureus was found in 23 (92%) samples, Salmonella was detected in only 2 (8%) samples, Aeromonas hydrophila was detected in only 1 (4%) samples. Listeria monocytogenes was not detected in any sample. According to the Egyptian standards, meat luncheon should be free from the above pathogens. Thus, only 2 (8%) samples of examined meat luncheon were accepted from the view point of microbiological quality. Irradiation at different dose levels used (1.5, 3.0, 5.0 kGy) greatly reduced all microbial counts, hence extended the shelf-life of meat luncheon at 4 deg. C ± 1 to 2, 3 and 4 weeks, respectively, against only 1 week of the unirradiated samples. Only meat luncheon samples irradiated at 5.0 kGy were free from all tested pathogens indicating that this irradiation dose was very effective in insuring microbial safety of meat luncheon. (Authors)

    Radioactive materials in Type B package have been transported safely on the sea under INF code and IAEA standard. Environmental and dose impact assessments have been made by assuming that a Type B package might be sunk into the sea since 1970s to enhance public understanding on safety of these transport. A method of the impact assessment consists of the estimation of release rates of radionuclide from a package, simulation of radionuclide concentration both in the coastal and global areas, and estimation of dose assessment for the public. We summarized the radiological impact at the submergence of Type B packages. The evaluated results of the dose equivalents by radiation exposure to the public for all materials were far below the dose equivalent limit of the ICRP recommendation (1mSv year -1 ). These assessments had a lot of uncertainties especially in the simulation of radionuclide concentration therefore the results might be overestimated. Estimations of ocean circulation and diffusion are important in this assessment. Ocean circulation model have been improved to simulate the material transport with higher resolutions. We developed more realistic methods to simulate both in the coastal and global areas to explain the evaluated results of the impacts to the public in an efficient manner. General circulation models around Japan and an ocean general circulation model were employed at the coastal and global areas respectively. It is impossible to validate the method directly because no accidents with release of radionuclide in the ocean have occurred since first sea transport of Type B packages. Therefore we simulated background radionuclide concentrations by fallouts ( 137 Cs) to validate the methods. Fallouts were input into ocean by nuclear weapon test since 1945 and mainly in 1960s. And their concentrations in the ocean have been measured to keep monitoring the artificial contaminations now. Observed database is useful to compare with simulated results in both

    The East Sea is one of the most vulnerable regions to unexpected Tsunami attacks in the world. Many catastrophic tsunamis have been occurred in this region. Among them, the Central East Sea tsunami occurred in 1983 has been recorded as the most devastating tsunami in modern Korean history. By employing a combined numerical model, the run-up heights of the tsunami are estimated along the Eastern coastline of the Korean Peninsula. The computed results are compared with available field measurements. A very reasonable agreement is observed. Several nuclear power plants are located along the Eastern coastline of the Korean Peninsula to get enough amount of cooling water. Furthermore, several more plants are now under construction. Generally, for the safe operation of nuclear power plants, a sea level drop may be more serious than a sea level rise. Once the water intake facilities, especially the bell mouth of a pump, are exposed above a sea water level, it will lead to the shutdown of a nuclear power plant. Sometimes the inhaled air can result in abrupt pressure surging within a mechanical cooling water system. Moreover, the ESWP (Essential Service Water Pump) is related to the safety of reactor. Thus, variation of sea level caused by tsunamis should be conservatively and accurately estimated

    The inclusion of software in safety related systems for nuclear power plants, makes it necessary to include the software quality assurance concept. The software quality can be defined as the adjustment degree between the software and the specified requirements and user expectations. To guarantee a certain software quality level it is necessary to make a systematic and planned set of tasks, that constitute a software quality guaranty plan. The application of such a plan involves activities that should be performed all along the software life cycle, and that can be evaluated through the so called quality factors, due to the fact that the quality itself cannot be directly measured, but indirectly as some of it manifestations. In this work, a software life cycle model is proposed, for nuclear power plant safety related systems. A set os software quality factors is also proposed , with its corresponding classification according to the proposed model. (author) [es

    1997-12-31

    People work at a nuclear plant within a structured environment. It is the programs, procedures and other ``tools`` that are used in the workplace that actually guide behaviours, and behaviours then guide performance. The safety culture in the workplace is ``the way we do things around here``. This culture is created by structures, behaviours and performance, and is characterized by three attributes: A questioning attitude; a rigorous and prudent approach; open 2-way communication. This paper discusses a model of safety culture which puts the operating experience or learning cycle program at the heart of the endeavor. This cycle also consists of three elements: Observation; reporting; learning. It is more of a theoretical paper than a report of success at this stage. However, the ideas presented are being used to design and implement a strong safety culture at Ontario Hydro`s Darlington Nuclear Station (4 x 932 Mwe CANDU units), and are beginning to show results. Programs designed for excellence in human performance have to provide clear simple structure, and draw people into alignment with the required behaviours. By making the structural elements and the alignment activities explicit an attempt can be made to ``design`` programs that will create and reinforce the required safety culture. The paper places the learning cycle at the heart of safety culture because the cycle aligns with the three attributes of safety culture. If an organization cannot learn from experience (i.e. change behaviours based on experience) it is doubtful whether it can build a strong safety culture. 2 refs.

    Full Text Available Aims: The aim of this study is to compare the effects of yoga program with supportive therapy counseling on mood states, treatment-related symptoms, toxicity, and quality of life in Stage II and III breast cancer patients on conventional treatment. Methods: Ninety-eight Stage II and III breast cancer patients underwent surgery followed by adjuvant radiotherapy (RT or chemotherapy (CT or both at a cancer center were randomly assigned to receive yoga (n = 45 and supportive therapy counseling (n = 53 over a 24-week period. Intervention consisted of 60-min yoga sessions, daily while the control group was imparted supportive therapy during their hospital visits. Assessments included state-trait anxiety inventory, Beck's depression inventory, symptom checklist, common toxicity criteria, and functional living index-cancer. Assessments were done at baseline, after surgery, before, during, and after RT and six cycles of CT. Results: Both groups had similar baseline scores. There were 29 dropouts 12 (yoga and 17 (controls following surgery. Sixty-nine participants contributed data to the current analysis (33 in yoga, and 36 in controls. An ANCOVA, adjusting for baseline differences, showed a significant decrease for the yoga intervention as compared to the control group during RT ( first result and CT (second result, in (i anxiety state by 4.72 and 7.7 points, (ii depression by 5.74 and 7.25 points, (iii treatment-related symptoms by 2.34 and 2.97 points, (iv severity of symptoms by 6.43 and 8.83 points, (v distress by 7.19 and 13.11 points, and (vi and improved overall quality of life by 23.9 and 31.2 points as compared to controls. Toxicity was significantly less in the yoga group (P = 0.01 during CT. Conclusion: The results suggest a possible use for yoga as a psychotherapeutic intervention in breast cancer patients undergoing conventional treatment.

In this study an exploration of initial and spoilage microbiota of sea bream fillets stored under air and commercial modified atmosphere packaging (MAP) at 0 and 5 °C was conducted by 16S rRNA gene sequence analysis of isolates grown on plates. Sensory evaluation and enumeration of total viable counts and spoilage microorganisms were also conducted to determine shelf life and bacterial growth respectively. Different temperatures and atmospheres affected growth and synthesis of spoilage microbiota as well as shelf life. Shelf life under air at 0 and 5 °C was 14 and 5 days respectively, while under MAP it was 20 and 8 days respectively. Initial microbiota were dominated by Pseudomonas fluorescens, Psychrobacter and Macrococcus caseolyticus. Different temperatures and atmospheres affected the synthesis of spoilage microbiota. At the end of shelf life, different phylotypes of Pseudomonas closely related to Pseudomonas fragi were found to dominate in most cases, while Pseudomonas veronii dominated in fillets under MAP at 0 °C. Furthermore, in fillets under MAP at 5 °C, new dominant species such as Carnobacterium maltaromaticum, Carnobacterium divergens and Vagococcus fluvialis were revealed. Different temperature and atmospheric conditions affected bacterial growth, shelf life and the synthesis of spoilage microbiota. Molecular identification revealed species and strains of microorganisms that have not been reported before for sea bream fillets stored under various conditions, thus providing valuable information regarding microbiological spoilage. © 2014 Society of Chemical Industry.

    The current state of research into polymer optical fiber (POF) sensors linked to safety in human life is summarized in this paper. This topic is directly related with new solutions for civil aircraft, structural health monitoring, healthcare and biomedicine fields. In the last years, the properties of polymers have been explored to identify situations offering potential advantages over conventional silica fiber sensing technology, replacing, in some cases, problematic electronic technology used in these mentioned fields, where there are some issues to overcome. POFs could preferably replace their silica counterparts, with improved performance and biocompatibility. Finally, new developments are reported which use the unique properties of POF.

    The life cycle assessment was employed to evaluate the environmental impacts of three farming systems (indoor intensive, semi-intensive and extensive systems) of sea cucumber living near Qingdao, China, which can effectively overcome the interference of inaccurate background parameters caused by the diversity of economic level and environment in different regions. Six indicators entailing global warming potential (1.86E + 04, 3.45E + 03, 2.36E + 02), eutrophication potential (6.65E + 01, -1.24E + 02, -1.65E + 02), acidification potential (1.93E + 02, 4.33E + 01, 1.30E + 00), photochemical oxidant formation potential (2.35E-01, 5.46E -02, 2.53E-03), human toxicity potential (2.47E + 00, 6.08E-01, 4.91E + 00) and energy use (3.36E + 05, 1.27E + 04, 1.48E + 03) were introduced in the current study. It was found that all environmental indicators in the indoor intensive farming system were much higher than those in semi-intensive and extensive farming systems because of the dominant role of energy input, while energy input also contributed as the leading cause factor for most of the indicators in the semi-intensive farming system. Yet in the extensive farming system, infrastructure materials played a major role. Through a comprehensive comparison of the three farming systems, it was concluded that income per unit area of indoor intensive farming system was much higher than those of semi-intensive and extensive farming systems. However, the extensive farming system was the most sustainable one. Moreover, adequate measures were proposed, respectively, to improve the environmental sustainability of each farming system in the present study.

    Flounder (Platichthys flesus) is a temperate marine fish that is well adapted to the brackish waters of the Baltic Sea. There are two sympatric flounder populations in the Baltic Sea, pelagic and demersal spawners, which differ in their spawning habitat and egg characteristics. In the present study, pelagic spawning flounder of the central Baltic Sea was studied. We examined whether variations in hydrological regime can explain fluctuations in flounder early life stages that have occurred over the past 30 years (1970-2005). Using generalized additive modeling to explain the abundance of flounder eggs and larvae in a Latvian ichthyoplankton dataset, we evaluate the hypothesis that the available reproductive volume, defined as the water column with dissolved oxygen larger than 1 ml/l and salinity between 10.6 and 12 PSU, affects the survival of flounder ichthyoplankton and determines recruitment success. Both reproductive volume and spawning stock biomass were significant factors determining flounder ichthyoplankton abundance. Different measures of water temperature did not contribute significantly to the variability of eggs or larvae. However, recruitment did not correlate to the supply of larvae. The findings presented in this study on the relationship between flounder reproduction, spawning stock biomass and reproductive volume, as well as the lack of correlation to recruitment, are valuable for the understanding of flounder ecology in the Baltic Sea, and for developing the management of the species.

    The annual discharge of petroleum hydrocarbons to the marine environment is about 3.2 million metric tonnes. About 15% of this discharge is caused by accidental spills at sea. The paper gives an overview of the commonly available oil spill response systems with emphasis on cold waters. In principle the oil spill combat systems at sea can be divided into mechanical containment and recovery, chemical dispersants and in-situ burning. The paper highlights the applicability and efficiency of these combat systems under various conditions (weathering state of the oil, sea state and wind, etc.). 25 refs., 10 figs

    The spectral albedos of sea ice were measured at Qaanaaq fjord in northwest Greenland. Spectral measurements were conducted for sea ice covered with snow and sea ice without snow where snow was artificially removed around measurement point. Thickness of the sea ice was approximately 1.3 m with 5 cm of snow over the sea ice. The measurements show that the spectral albedos of the sea ice with snow were lower than those of natural pure snow especially in the visible regions though the spectral shapes were similar to each other. This is because the spectral albedos in the visible region have information of not only the snow but also the sea ice under the snow. The spectral albedos of the sea ice without the snow were approximately 0.4 - 0.5 in the visible region, 0.05-0.25 in the near-infrared region and almost constant of approximately 0.05 in the region of 1500 - 2500 nm. In the visible region, it would be due to multiple scattering by an air bubble within the sea ice. In contrast, in the near-infrared and shortwave infrared wavelengths, surface reflection at the sea ice surface would be dominant. Since a light absorption by the ice in these regions is relatively strong comparing to the visible region, the light could not be penetrated deeply within the sea ice, resulting that surface reflection based on Fresnel reflection would be dominant. In this presentation we also show the results of comparison between the radiative transfer calculation and spectral measurement data.

    There is growing international concern about the increasing levels of greenhouse gases in the atmosphere, particularly CO2 and methane. The emissions of methane derived from human activities are associated with large flows and very low concentrations, such as those emitted from landfills and wastewater treatment plants, among others. The present work was focused on the biological methane degradation at diffuse concentrations (0.2% vv(-1)) in a conventional biofilter using a mixture of compost, perlite and bark chips as carrier. An extensive characterization of the process was carried out at long-term operation (250 days) in a fully monitored pilot plant, achieving stable conditions during the entire period. Operational parameters such as waterings, nitrogen addition and inlet loads and contact time influences were evaluated. Obtained results indicate that empty bed residence times within 4-8 min are crucial to maximize elimination rates. Waterings and the type of nitrogen supplied in the nutrient solution (ammonia or nitrate) have a strong impact on the biofilter performance. The better results compatible with a stable operation were achieved using nitrate, with elimination capacities up to 7.6 ± 1.1 g CH4 m(-3 )h(-1). The operation at low inlet concentrations (IC) implied that removal rates obtained were quite limited (ranging 3-8 g CH4 m(-3 )h(-1)); however, these results could be significantly increased (up to 20.6 g CH4 m(-3) h(-1)) at higher IC, which indicates that the mass transfer from the gas to the liquid layer surrounding the biofilm is a key limitation of the process.

    Preparations for establishment of a LILW repository in Croatia have reached a point where a preliminary safety assessment for the prospective facility is being planned. The planning is not based upon the national regulatory framework, which does not require such an assessment at this early stage, but upon the interagency BSS and the IAEA RADWASS programme recommendations because the national regulations are being revised with express purpose to conform to the most recent international standards and good practices. The Waste
