    From 2003, the Nuclear Regulatory Authority (RNA) has worked in the implementation of a Geographical Information System (SIG) for the planning and the intervention in emergencies, with special emphasis in the nuclear emergencies. The main objective of the SIG developed in the ARN is to give the necessary support for the planning, training and application of the actions of radiological protection necessary in front of a nuclear emergency, offering the geo referenced cartographic base, the readiness of logistical resources in the whole country, incorporating results of models of forecast of consequences and environmental measurements during the emergency, facilitating the analysis of this information in real time and facilitating the presentation of results for the decision making. The cartographic base is constituted of demographic, social, economic data identification of main actors interveners in the emergency, vial infrastructure and natural characteristics of the area in question. In this work the main characteristics of the implemented SIG are presented including the conceptual standards of design that contemplate the international requirements for the planning and answer in the event of nuclear emergencies, the current state of the system and the foreseen evolution. A description of the opposing problems during its implementation that can be common to many countries of the region is also presented, as well as the obtained experience of its use in preparation tasks for emergencies and in mocks.

    Planning of the response to emergencies in nuclear plants is regulated by the Basic Nuclear Emergency Plan (PLABEN). This basic Plan is the guidelines for drawing up, implementing and maintaining the effectiveness of the nuclear power plant exterior nuclear emergency plans. The five exterior emergency plans approved as per PLABEN (PENGUA, PENCA, PENBU, PENTA and PENVA) place special emphasis on the preventive issues of emergency planning, such as implementation of advance information programs to the population, as well as on training exercises and drills.

    1989-01-01

    This paper aims to stimulate discussions between nuclear engineers and the radiological protection professions in order to facilitate planning for nuclear emergencies. A brief review is given of the response to nuclear accidents. Studying accidents can lead to prevention, but some effort must be put into emergency response. Such issues as decontamination and decommissioning, socio-economic consequences, education and training for nuclear personnel and exercises and drills, are raised. (UK)

  7. Emerging nuclear suppliers

    International Nuclear Information System (INIS)

    Sands, A.

    1990-01-01

    Efforts to prevent the spread of nuclear weapons have usually taken two tracks: The traditional approach has concentrated on a potential proliferant's perceived need for nuclear technology and possibly weapons; a second approach has targeted the supply side of the proliferation equation. The issue being examined in this book---emerging nuclear suppliers---falls between these two approaches. The potential proliferants have emerged as possible unrestrained suppliers of nuclear materials and technology. They threaten the entire nonproliferation regime by their exporting, not their weapons development. Analyzing and understanding the issue of emerging suppliers requires a refined definition of suppliers in general. The simple dichotomy of traditional versus emerging suppliers is no longer an adequate framework for analysis. Suppliers differ significantly in their technical capabilities, experience, and regime involvement, and these distinctions result in different nuclear export policies

    Since the early 1980s, a growing amount of attention has been paid to a small group of mostly developing countries that have come to be called the emerging nuclear suppliers. Argentina and Brazil, China and South Korea, India and Pakistan, Spain and Yugoslavia have frequently been mentioned in this category. Their actual and potential nuclear export dealings and policies have been the subject of academic writings and policy papers, of scholarly symposia and exchanges at meetings of the traditional nuclear suppliers. With foundation and other support, UCLA's Center for International and Strategic Affairs has begun a major project to develop a database on the transactions, policies, and export control institutions of the emerging suppliers. This chapter provides some guidelines for policy toward the emerging nuclear suppliers

  9. Communication in nuclear emergency

    In order to take protection measures smoothly at the time of emergency in nuclear power stations and others, it is necessary to prepare information communication facilities mutually among disaster prevention organizations including the state and information transmission network for residents in surrounding areas. The matters decided in ''the measures to be taken for the time being for the countermeasures to prevent disaster in nuclear power stations and others'' are shown. In order to avoid the congestion of communication, the exclusively used communication systems are adopted for disaster prevention organizations, in which facsimile is used to transmit graphic information. The data communication circuits for distributing SPEEDI are installed between Science and Technology Agency, Nuclear Power Safety Technology Center and respective prefectures. The routes, means and order of notices must be confirmed beforehand mutually among the related organizations. As to the general communication for disaster countermeasures, the communication systems in ministries and agencies are described. (K.I.)

    2005-01-01

    The role of a procedure depends not only on its own capabilities but also on a cost/effective comparison with alternative technique giving similar information. Starting from the definition of emergency as a sudden unexpected occurrence demanding immediate action, the role of nuclear medicine (NM) is difficult to identify if it is not possible to respond 24h a day, 365 days a year, to clinical demands. To justify a 24 h NM service it is necessary to reaffirm the role in diagnosis of pulmonary embolism in the spiral CT era, to spread knowledge of the capabilities of nuclear cardiology in reliability diagnosis myocardial infraction (better defining admission and discharge to/from the emergency department), to increase the number of indications. Radionuclide technique could be used as first line, alternative, complementary procedures in a diagnostic tree taking into account not only the diagnosis but also the connections with prognosis and therapy in evaluating cerebral pathologies, acute inflammation/infection, transplants, bleeding, trauma, skeletal, hepatobiliary, renal and endocrine emergencies, acute scrotal pain

  12. Nuclear emergency preparedness in Canada

    International Nuclear Information System (INIS)

    1993-03-01

    The preparedness of utilities and government agencies at various levels for dealing with nuclear emergencies occurring at nuclear reactors in Canada is reviewed and assessed. The review is centered on power reactors, but selected research reactors are included also. Emergency planning in the U.S.A., Germany and France, and international recommendations on emergency planning are reviewed to provide background and a basis for comparison. The findings are that Canadians are generally well protected by existing nuclear emergency plans at the electric utility and provincial levels but there are improvements that can be made, mainly at the federal level and in federal-provincial coordination. Ten issues of importance are identified: commitment to nuclear emergency planning by the federal government; division of federal and provincial roles and responsibilities; auditing of nuclear emergency preparedness of all levels of government and of electric utilities; the availability of technical guidance appropriate to Canada; protective action levels for public health and safety; communication with the public; planning and response for the later phases of a nuclear emergency; off-site exercises and training; coordination of international assistance; and emergency planning for research reactors.

    In 2010 the nuclear power plant of Laguna Verde will implement the extended power upbeat in both units of the plant. Agree with methodology of NEDC-33004P-A, (constant pressure power up rate), and the source term of core, for accidents evaluations, were increased in proportion to the ratio of power level. This means that for the case of a design basis accident of loss of coolant an increase of power of 15% originated an increase of 15% in dose to main control room. Using the method of NEDC-33004P-A to extended power upbeat conditions was determined that the dose value to main control room is very near to regulatory limit established by SRP 6.4. By the above and in order to recover the margin, the nuclear power plant of Laguna Verde will calculate an alternative source term following the criteria established in RG 1.183 (alternative radiological source term for evaluating DBA at nuclear power reactor). This approach also have a more realistic dose value using the criterion of 10-CFR-50.67, in addition is predicted to get the benefit of additional operational flexibilities. This paper present the proposal of implementing the alternative source term in Laguna Verde. (Author)

    The nuclear emergency planning in Norway is forming a part of the Search and Rescue Service of the country. Due to the fact that Norway do not have any nucleat power reactor, the nuclear emergency planning has not been given high priority. The problems however are a part of the activity of the National Institute of Radiation Hygiene, and the emergency preparedness is at the present time to a large extent based on the availability of professional health physicists and their knowledge, rather than established practices

    As in all other industries, the nuclear facilities can be the object of accidents whose consequences go beyond the limits of their site and consequently radioactive releases would be issued in the environment justifying the protection measures of population. Even if all the precautions were taken during the stages from the design to the operation, to reduce the risk of accident in nuclear installations, this risk can not be completely suppressed. For the radiological risk, as for the other major risks, the protection of the public always was taken in consideration by public power. The nuclear emergency plan gives the opportunity to have a quick appropriate reaction to a sudden event, which has (or might have) direct consequences for the population. The Moroccan public authorities had proceeded to reinforce at the national level, the control of nuclear safety and protection against radiation by the set up of a new nuclear safety authority. Evidently, the organization and the management of a nuclear and/or radiological emergency were at centre of this reform. Taking into account the subjective risk of radiological terrorism, the authorities should reinforce measurements guaranteeing radiological safety and security, and elaborate the appropriate emergency plans. The aim of this paper is to give a progress report on nuclear emergency plan aspects and to present a corresponding organization which could be applied by national authority. (authors)

  20. Studying the emerging nuclear suppliers

    1990-01-01

    None of these events---nor any of the many others that are cited in the case studies of this book---can be singled out as heralding a revolutionary transformation of the global nuclear marketplace. The cumulative effect of such developments, however, may well be the emergence of a market in the year 2000 that is far less concentrated than today's market for nuclear reactors and fuel cycle technology. If this gradual structural transformation is accompanied by the entry into the market of new buyers and sellers that do not accept the Nuclear Non-Proliferation Treaty (NPT), safeguards administered by the IAEA, or other international norms directed at preventing the spread of nuclear weapon capabilities, the result may indeed have revolutionary dimensions for the business, diplomacy, and research of nuclear energy. A similar outcome could arise even f these norms are widely accepted but are not matched by an increase in the resources available to national governments and key international agencies that implement these norms. This paper identifies some of the pitfalls that researchers often encounter in researching the emerging suppliers and will outline some basic ground rules to guide the collection and interpretation of empirical evidence on supplier behavior

    A equipment is reliable if it fulfills the function for which was designed and when it is required. To implement a project of reliability in a nuclear power plant this associate to a process of continuous analysis of the operation, of the conditions and faults of the equipment. The analysis of the operation of a system, of the equipment of the same faults and the parts that integrate to equipment take to identify the potential causes of faults. The predictive analysis on components and equipment allow to rectify and to establish guides to optimize the maintenance and to guarantee the reliability and function of the same ones. The reliability in the equipment is without place to doubts a wide project that embraces from the more small component of the equipment going by the proof of the parts of reserve, the operation conditions until the operative techniques of analysis. Without place of doubt for a nuclear power plant the taking of decisions based on the reliability of their systems and equipment will be the appropriate for to assure the operation and reliability of the same one. In this work would appear the project of reliability its processes, criteria, indicators action of improvement and the interaction of the different disciplines from the Nuclear Power Plant of Laguna Verde like a fundamental point for it put in operation.

    One of the functions of the Peruvian Institute of Nuclear Energy (IPEN), Lima, Peru is the control of sources of ionizing radiation. For this, they have the Oficina Tecnica de la Autoridad Nacional (OTAN) which has the necessary infrastructure to issue technical standards, conducting inspections, issuing authorizations and punish according to the existing legislation. OTAN has decided to address this issue and is taking into account the IAEA recommendations, especially the Safety Requirements GS-R-3: Management System facilities and activities and offering advice on the establishment and improvement of integrated management systems, including safety requirements that are not in the ISO 9001 standard and are also considered the requirements of technological safety, security, quality, economic, environmental and health. The working plan is detailed and the activities that are carried out after the scientific visit to a regulator organ, which has experience in the execution of a Quality Management System, consequence of a work initiated for more than four decades ago.

  3. Nuclear emergencies and protective actions

    International Nuclear Information System (INIS)

    Sjoeblom, Klaus

    1995-01-01

    Although technical improvements have increased the safety of new and old nuclear power plants, many simultaneous component failures and/or human errors are improbable but possible. Both the plant (on-site) and the nearby area (off-site) have emergency plans. Rescue service authorities are responsible of the off-site. The main protective actions are sheltering, evacuation and iodine ingestion. The Loviisa off-site emergency plan assumes that a major part of this population takes care of their own protective actions; Rescue service authorities can then concentrate on the coordination activities and to those people who need help. To be able to carry out the protective actions timely and effectively the people should have information on radiation risk and emergency planning. In case of a potential accident the local population should follow the rescue service information and know how to shelter and how to evacuate themselves. Though there are many stockpiles of iodine pellets in the area the rescue service authorities recommend that each household should purchase iodine pellets for their own need. The utility and the rescue service authorities have distributed information brochures to all homes within 30 km from Loviisa NPP since 1990. This brochure gives information on radiation and protective actions in case of an accident. Because the brochures might not stay available and so also the local telephone book contains this information

    The practice followed in planning, preparing and conducting offsite nuclear emergency exercises in the Province of Ontario, Canada, is described. In addition, some of the main issues that arise during this process are discussed, as well as Canadian experience in dealing with them. The planning process starts with basic decisions on the aim, scope and duration of the exercise. It proceeds through selection of the exercise objectives and participants, the development of scenarios and incident lists culminating in a master scenario and a master incident list, and finally, the production of control inputs. Preparations include the setting up of a planning organization, making arrangements for exercise control and evaluation, and the required logistics. Some aspects of international exercises are also covered, based upon experience with joint exercises with the U.S.A

    Stahl, K.

    1990-01-01

    The emergence of new supplier states of nuclear technology within the Third World has raised concern, if those nuclear supplier states will promote an unrestricted and uncontrolled transfer of nuclear technology to developing countries and augment the risk of nuclear weapons proliferation. The article analyses the nuclear export capacities, nuclear exports and the export policy of Argentina, Brazil and India. Argentina is considered as the most important emerging nuclear supplier state in the Third World. Nuclear exports have to be authorisized by the government in all three states and will be covered by IAEA-safeguards in the recipient country. The three states will exercise restraint in the transfer of sensitive nuclear technology. Nuclear exports of Argentina, Brazil and India so far will not augment the danger of nuclear weapons proliferation. (orig./HSCH) [de

    U.S.NRC determined an obligation to build a nuclear power plant emergency response organization for both on-site and off-site. Millstone Nuclear Power Plants have 3 nuclear reactors and 2 of 3 still in commercial operation. Reactor unit 1, BWR type has been permanently shut down in 1998, while the two others, units 2 and 3 obtain the extended operating license respectively until 2035 and 2045. As a nuclear installation has the high potential radiological impact, Millstone nuclear power plant emergency response organization must establish both on-site or off-site. Emergency response organization that is formed must involve several state agencies, both state agencies and municipality. They have specific duties and functions in a state of emergency, so that protective measures can be undertaken in accordance with the community that has been planned. Meanwhile, NRC conduct their own independent assessment of nuclear power plant emergencies. (author)

    Nuclear or radiologic emergencies are defined as incidents that are caused by radioactive substance or by other sources of radiation and can pose a serious hazard to public health. In case of nuclear or radiologic emergencies, radioactive rays will damage the human body and bring about psychological and mental stress, resulting in a series of social psychological effects. The key to medical rescue for nuclear or radiologic emergencies is to take effective measures which can minimize the body harm resulting from nuclear or radiologic emergencies and maintain social stability. This article reviews the personnel protection, on-the-spot salvage, treatments of various harm, and prevention of public psychological effect following nuclear or radiologic emergencies. (authors)

    The need for nuclear power in Latin American countries is surveyed. It is concluded that Latin America offers the greatest external market for all exporters of nuclear reactors and associated services in the near future. Mexico, Venezuela, Ecuador, and Bolivia are the only countries with fossil-fuel reserves adequate to meet their requirements in the next 20 to 30 years. Nuclear power is a necessity to maintain or improve the standard of living in the countries of Brazil, Argentina, Chile, and Peru

    The paper describes how to develop a balanced emergency plan, which realistically reflect the interfaces with various emergency organizations. The use of resources should be optimized with focusing on the most likely accidents. The pitfalls of writing an emergency plan without ''big picture'' in mind should be avoided. It is absolutely essential to have a clear definition of responsibilities and to have proper understanding of the tasks in between all counterparts in the emergency preparedness. Special attention should be paid to off-site part of the nuclear emergency preparedness, because the people involved in it usually receive less training than the on-site personnel and they are not specialized for nuclear emergencies but deal with all sorts of emergencies.

    Full text: Tragic events of September eleventh have made nuclear terrorism dangers more evident. In the light of increased terrorism preventing the spread of nuclear and nuclear related items as well as radioactive materials that can be used for production so-called 'dirty bomb'is an urgent global claim. Nuclear Security issues cover multiple aspects of the security and first of all the threat from nuclear terrorism, detection and protection of illicit trafficking of nuclear materials and other radioactive sources, legal shipment of such type materials as well as nuclear related dual use items. In the face of emerging threats the prevention of proliferation by the development of effective national system of nuclear export controls is hugely important for transit countries like Azerbaijan with underdeveloped export controls and strategic locations along trade and smuggling routes between nuclear suppliers States and countries attempting to develop nuclear weapons or any nuclear explosive devices. Thus, in the face of increasing international threat from nuclear terrorism the role and place of Azerbaijan Republic in the struggle against terrorism increases. In this context it is very important to establish effective national capabilities for detection and prevention of illicit trafficking of radioactive and nuclear materials as well as nuclear related dual use items across Azerbaijan's borders. One of the ways for enhancing and strengthening existing activities in this field is carrying out joint actions between scientists and enforcement officials in order to improve knowledge of the front-line customs and border guard inspectors concerning multiple aspects of Nuclear Security

    Counterterrorism is not the province of the emergency manager. Generally law enforcement has that role. Instead, the emergency manager's role is crisis management; the responsibility is to be the focal point for the chief executive officer (mayor, governor, or national executive) regarding the protection of the population. Managers must be able to gather and synthesize sufficient information, rapidly and accurately, on which to base sound decisions. To do so, they must have a highly efficient, coordinated emergency management organization in place at the state and local levels of government, and there must be a workable plan for emergency operations that integrates all public safety forces into an effective response to all types of emergencies. A major goal of emergency management is to ensure that government is in control and that the public perceives that the system is working. All states have an emergency management organization at the state level, as do most counties and large cities. However, some states and local governments, particularly those that have nuclear power plants within their borders, are better staffed, equipped, and trained than others to deal with nuclear incidents. States with nuclear facilities have an emergency management organization, an emergency plan, and adequate communications, equipment, and trained personnel to handle a nuclear accident or incident at a plant. 21 references

The improvements include the construction of a purpose built Off-Site Emergency Centre for each of its two power stations and the development of a computer based information management system to facilitate the rapid distribution of information on an emergency to local, regional and national agencies. A computer code has also been developed to allow the rapid assessment of the effects of any accidental release on the local population. The improvements to the emergency facilities have been coupled with changes in local and national arrangements for dealing with a civil nuclear emergency. The use of airborne surveying techniques for rapidly determining levels of deposited activity following an accident is also being examined and preliminary airborne surveys have been carried out.

    1990-01-01

    The number of states capable of exporting nuclear material, technology, equipment, and services is large and growing. Once confined primarily to states party to the Nuclear Non-Proliferation Treaty (NPT), the list of actual and potential nuclear suppliers now includes many countries that do not subscribe to the NPT or to other international nuclear export control agreements. Although international control accords---such as the Nuclear Exporters' (Zangger) Committee and the London Nuclear Suppliers Group (NSG) guidelines---do not prohibit the export of sensitive nuclear materials and equipment, they do reduce the risks of proliferation by imposing international safeguards as a condition for export. The purpose of this book---the culmination of one phase of an ongoing international research project on the emerging nuclear suppliers and nonproliferation---is to remedy, at least in part, this data deficiency

    Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

    Weinberg, A.M.

    1984-01-01

    Nuclear energy is faltering in many places - especially in the USA: should it be written off. The author sees underlying trends that justify a more optimistic view of nuclear energy's future - the continuing tendency for the electricity intensity of economic activity to rise while the total energy intensity falls; a consistently favourable price trend for electricity compared with energy prices generally - a trend that may become more favourable if his judgment that nuclear plants will turn out to be very long-lived is borne out by events; the substitution of electricity-based processes in industry for older processes; and the development of ultra-safe reactors which will remove once and for all the fears of accidents such as the one that occurred at Three Mile Island.

    After having recalled that India has always been interested in nuclear energy, this article outlines that this country is suffering from an increasing air pollution with noticeable impacts on health (thousands of deaths per year due to pollution), and, even though its CO 2 emissions have very much increased during the past decades, its governments want to rely on nuclear energy to face climatic challenges. The article also outlines that the country is facing increasing energy needs when about 300 millions of inhabitants do not have access to electricity. New sources of energy production must then be developed, preferably de-carbonated sources (hydraulic, wind, nuclear, solar, so on). Therefore, progress must be made to reduce the share of fossil energy. The author proposes a brief presentation of the Indian nuclear programme, with its 20 existing reactors and 6 reactors under construction. A strategy has been defined to exploit as many PWRs as possible, to introduce fourth generation reactors, and to use a thorium fuelled reactor. The framework of the French-Indian partnership is briefly presented, and the involvements of AREVA for the construction of six EPRs, and of the CEA for the development of fourth generation reactors are evoked

    The political and economic upheavals which have taken place in Eastern Europe have had an impact on radiation and nuclear safety throughout Europe. Emergency preparedness systems for unexpected nuclear events have been developed further in all European countries, and prosperous western nations have invested in improving the safety of East European nuclear power plants. The economic crisis facing countries of the former Soviet Union has also promoted illicit trade in nuclear materials; this has made it necessary for various border guards and police authorities to intensify their collaboration and to tighten border controls. On 3-4 October 1995, Finnish Centre for Radiation and Nuclear Safety (STUK) arranged a seminar on nuclear threats and emergency preparedness in Finland. In addition to STUK experts, a wide range of rescue and civil defence authorities, environmental health specialists and other persons engaged in emergency preparedness attended the seminar. The publication contains a compilation of reports presented at the seminar. The reports cover a broad spectrum of nuclear threats analyzed at STUK, the impacts of radioactive fallout on human beings and on the environment, and preparedness systems by which the harmful effects of radiation or nuclear accidents can, if necessary, be minimized.

    Full text: In 1998, the Executive signed the decree 1390, which defined the scope and the procedures corresponding to the Nuclear Activity Law. In this decree, the new functions of the Nuclear Regulatory Authority (ARN) are described, being the most important related to preparation and response for a nuclear emergency the following ones: 1) ARN must provide protection from harmful effects of ionizing radiations under normal conditions and emergency situations; 2) ARN must advise the Executive in case of radiological and nuclear emergencies; 3) ARN shall establish the criteria for the emergency plans of the facilities and train the members of neighbor public to the facilities in case of nuclear emergencies; 4) The emergency plans developed by local, provincial and national authorities must be approved by the ARN; 5) ARN shall lead the actions within the area covered by the emergency plans of the facilities. Security Forces and the Representatives of Civil Institutions shall report the designated ARN officer. The ARN recognized immediately the responsibility imposed by this law and, at the same time, the opportunity of improving the handling of emergencies through a centralized direction of the operations. Under this frame, ARN created the Radiological Emergencies Intervention System (SIER) with the goal of taking charge of the preparation and the handling of emergency situations. From the beginning, the purpose of the SIER was to improve the preparation and response to nuclear emergencies in a regular form, bearing in mind the cultural and socioeconomic situation of the country, as well as the local peculiarities. The first steep to achieve such a target was to gain the confidence of other organizations included in the response on the ARN technical and operational aptitude to lead the actions inside the emergency area and, later, to establish the pertinent arrangements. The strategy chosen by ARN to respond to nuclear emergencies consists in establishing an expert

    The purpose of planning for radiation emergency response is to ensure adequate preparedness for protection of the plant personnel and members of the public from significant radiation exposures in the unlikely event of an accident. With a number of safety features in the reactor design and sound operating procedures, the probability of a major accident resulting in the releases of large quantities of radioactivity is extremely small. However, as an abundant cautious approach a comprehensive radiation emergency response preparedness is in place in all the nuclear power plants (NPPs). Radiation Emergency in NPPs is broadly categorized into three types; plant emergency, site emergency and off-site emergency. During off site emergency conditions, based on levels of radiation in the environment, Civil Authorities may impose several counter measures such as sheltering, administering prophylaxis (stable iodine for thyroid blocking) and evacuation of people from the affected area. Environmental Survey Laboratory (ESL) carries out environmental survey extensively in the affected sector identified by the meteorological survey laboratory. To handle emergency situations, Emergency Control Centre with all communication facility and Emergency Equipment Centre having radiation measuring instruments and protective equipment are functional at all NPPs. AERB stipulates certain periodicity for conducting the exercises on plant, site and off site emergency. These exercises are conducted and deficiencies corrected for strengthening the emergency preparedness system. In the case of off site emergency exercise, observers are invited from AERB and Crisis Management Group of Department of Atomic Energy (DAE). The emergency exercises conducted by Nuclear Power Plant Sites have been very satisfactory. (author)

    The invention concerns a circuit called 'of emergency help' intended to remove, in a safe and quick manner, the residual thermal power on the safety vessel of a fast neutron reactor cooled by a liquid metal flow, in the event of a failure occurring inside the main reactor vessel or on it. This system includes a network of spray nozzle tubes, distributed around and near the external surface of the safety vessel, to project on to the surface of the vessel a mist of a liquid having high latent vaporisation heat. The steam produced on contact with the safety vessel is collected in the space provided between the safety vessel and the external protection vessel by at least one collector pipe for dischaging this steam outside the vessel. Under a preferred design mode of the invention the liquid is water the use of which turns out to be particularly advantageous in practice owing to its favourable physical properties and its low cost [fr

    A new national organisation for nuclear emergency preparedness was established in Norway in 1993, based on experiences from the Chernobyl accident. This organisation is based on authorities and research institutions which in a normal situation have responsibilities and knowledge in fields that are also of major importance in a nuclear accident situation. The national emergency preparedness organisation consists of the Ministerial Co-ordination Committee, the Advisory Committee for Nuclear Accidents and their secretariat at the Norwegian Radiation Protection Authority, and an Information Group. The organisations participating in the Advisory Committee operate measuring networks, stations and laboratories. In an early phase of an accident, a minor group from the Advisory Committee forms a Crisis Committee for Nuclear Accidents. This committee has been delegated the authority to make decisions in this phase. The organisation represented by its secretariat at the Norwegian Radiation Protection Authority is responsible for coordinating the emergency planning, the measuring capacities and the professional needs ordinarily. The secretariat is on call 24 hours a day as point of contact according to bilateral and international agreements on early notification. In this paper the features of the emergency preparedness organisation are presented. (Author)

    With the initiation of the first international nuclear emergency exercise INEX 1, performed as a table-top exercise in 1993, the international community tested, for the first time, approaches and policies in place to manage a nuclear or radiological emergency. INEX 1 with its related workshops led to a wealth of lessons learned and to an improvement in nuclear emergency management. The INEX 2 exercise series, initiated by the NEA and performed between 1996 and 1999, established an international nuclear emergency 'exercise culture' leading to a clear improvement of the international aspects of nuclear emergency preparedness and management. INEX 2 was a series of four command post exercises based on national nuclear emergency exercises in Switzerland, Finland, Hungary and Canada. Simulated accidents at nuclear power plants were used to test existing procedures in emergency response and management, and to analyse local, regional, national and international emergency plans under realistic conditions. In addition, the exercises allowed the participating countries to gain experience using new concepts and tools. The most significant result of INEX 2 and a major step forward in nuclear emergency management was the development of a new communication and information exchange strategy, which is currently implemented by various NEA member countries as well as by the international community in general. The objective of this new strategy is to assist the decision-maker by improving the selection of the data transmitted, by encouraging the transmission and reception of such data and information using modern communication methods, e.g. secure world wide web technologies, and by defining emergency monitoring and modelling needs. To test the validity and usefulness of the newly-developed strategy, the NEA proposed to organize an international nuclear emergency exercise, INEX 2000, similar in scope to the INEX 2 exercises. In addition, the NEA suggested to include, for the first

    The Hungarian Government had established in 1989 on the basis of national and international experience the National System for Nuclear Emergency Preparedness (NSNEP). Its guidance is ad-ministered by the Governmental Commission for Nuclear Emergency Preparedness (GCNEP). The work of the Governmental Commission is designated to be assisted by the Secretariat, the Operational Staff and by the Technical Scientific Council. The leading and guiding duties of the relevant ministries and national agencies are performed by the Sectional Organisations for Nuclear Emergency Preparedness (SONEP), together with those of the Metropolitan Agencies and of the county agencies by the Metropolitan Local Committee (MLCNEP) and by County Local Committees. The chairman of the Governmental Commission is the Minister of the Interior whose authority covers the guidance of the NSNEP's activities. The Secretariat of the Governmental Commission (SGC) co-ordinates the activities of the bodies of the Governmental Commission, the sectional organisations, the local committees for nuclear emergency preparedness and those of the other bodies responsible for implementing action. The Emergency Information Centre (EIC) of GCNEP as the central body of the National Radiation Monitoring, Warning and Surveillance System provides the information needed for preparing decisions at Governmental Commission level. The technical-scientific establishment of the governmental decisions in preparation for nuclear emergency situations and the elimination of their consequences are tasks of the Technical-Scientific Council. The Centre for Emergency Response, Training and Analysis (CERTA) of the Hungarian Atomic Energy Authority (HAEA) may be treated as a body of the Governmental Commission as well. The National Radiation Monitoring, Warning and Surveillance System (NRMWSS) is integral part of the NSNEP. The NRMWSS consists of the elements operated by the ministries and the operation of nation-wide measuring network in

    Through the use of internationally organised, multinational drills, a wealth of experience and knowledge have been gained at both the national and international levels. The lessons learnt primarily concerned the early, urgent-communication phases of nuclear emergencies, and are currently in the process of being consolidated and incorporated into national structures and approaches. The focus of current works is shifting towards later accident phases, particularly to the mid-term phase, when control has been regained of the emergency situation but the accident consequences have yet to be addressed. In addition to these ''classic'' nuclear emergency response interests, since the 11 september 2001 national authorities have been concerned with accident response capabilities in case of terrorist acts that might involve radiation.

    This paper reviews the status of assessment and prognosis system for nuclear emergency response in Korea, especially atmospheric dispersion model. The Korea Institute of Nuclear Safety (KINS) performs the regulation and radiological emergency preparedness of the nuclear facilities and radiation utilizations. Also, KINS has set up the "Radiological Emergency Technical Advisory Plan" and the associated procedures such as an emergency response manual in consideration of the IAEA Safety Standards GS-R-2, GS-G-2.0, and GS-G-2.1. The Radiological Emergency Technical Advisory Center (RETAC) organized in an emergency situation provides the technical advice on radiological emergency response. The "Atomic Computerized Technical Advisory System for nuclear emergency" (AtomCARE) has been developed to implement assessment and prognosis by RETAC. KINS developed Accident Dose Assessment and Monitoring (ADAMO) system in 2015 to reflect the lessons learned from Fukushima accident. It incorporates (1) the dose assessment on the entire Korean peninsula, Asia region, and global region, (2) multi-units accident assessment (3) applying new methodology of dose rate assessment and the source term estimation with inverse modeling, (4) dose assessment and monitoring with the environmental measurements result. The ADAMO is the renovated version of current FADAS of AtomCARE. The ADAMO increases the accuracy of the radioactive material dispersion with applying the LDAPS(Local Data Assimilation Prediction System, Spatial resolution: 1.5 km) and RDAPS(Regional Data Assimilation Prediction System, Spatial resolution: 12km) of weather prediction data, and performing the data assimilation of automatic weather system (AWS) data from Korea Meteorological Administration (KMA) and data from the weather observation tower at NPP site. The prediction model of the radiological material dispersion is based on the set of the Lagrangian Particle model and Lagrangian Puff model. The dose estimation methodology

    Now days in Chile there are more of 43 Nuclear Medicine centers; most of them have gamma cameras in order to study physiological process in diagnostic and treatment of patients pathologies. This requires having the equipment in optimal operating condition and it is ensured with quality control programs that are based on a series of tests relating to protocols, such as TECDOC-602 y AAPM No.6. Planar test often applied in gamma cameras including: spatial resolution, spatial linearity, sensitivity and uniformity. SPECT tests consider: tomography uniformity, rotation center tomography resolution and total performance. The tests in dose calibrator are: background measurement, accuracy, precision, linearity and reproducibility. The tests above require the use of radioactive sources and specific simulators patterns or phantom based on international standards such as The National Electrical Manufacturers Association (Nema), International Atomic Energy Agency (IAEA) and The American Association of Medical Physics (AAPM). In this work we carried out several tests of quality control in a Nuclear Medicine Center of Temuco and we propose to implement the applied methodology in others similar Chilean centers. (author)

    International Nuclear Information System (INIS)

    1992-06-01

    The responsibility for Denmark's preparedness for nuclear emergencies lies with the Ministry of the Interior and the Civil Defense administration. The latter is particularly responsible for the presented plan which clarifies the organization and the measures to be taken in order to protect the public where, in the event of such an emergency, it could be in danger of radiation from radioactive materials. The main specifications of the plan, the activation of which covers the whole country, are that daily monitoring should be carried out so that warnings of nuclear accidents can be immediately conveyed to the relevant parties and that immediate action can be taken. These actions should result in the best possible protection against nuclear radiation so that acute and chronic damage to the health of members of the public can be restricted. The public, and relevant authorities should be informed of the situation and it should be attempted to regulate the reactions of individuals and of the society in general in such a way that damage to health, or social and economical conditions, can be restricted as much as possible. Denmark has not itself any atomic power plants, but some are located in neighbour countries and there are other sources such as nuclear research reactors, passing nuclear-driven ships etc. The detailed plan also covers possible sources of radiation, the nature of related damage to health, international cooperation, legal aspects, and a very detailed description of the overall administration and of the responsibilities of the organizations involved.

    Since North Korea announced the underground nuclear test on last October 9th, 2006, many countries around the world have worried about the atmospheric dispersion and pollution of radioactive materials crossing the border by the clandestine nuclear test. After that time, verifying the existence of nuclear test by detecting radioactive materials such as xenon, I-131, and Cs-134 at the early stage of radiological emergency, locating the position of test site by backward trajectory analysis, and chasing the moving path of airborne radionuclide have been heavily issued. And collection of airborne radioactivity and gamma radiation monitoring technology using an aircraft have been recently examined by an authority concerned in South Korea. Although various techniques of radiological aerial monitoring have been developed and operated around the world, the relevant technical development or research is still required. In order to decide potential measuring location and time within the framework of radiological monitoring system, we use HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory) model developed by National Oceanic and Atmospheric Administration (NOAA) of U.S. Department of Commerce. The model is validated and assessed against North Korea's nuclear test. Calculation results of radionuclide trajectory show a good agreement with measured values. Backward trajectory analysis is useful to track the radiological source term, possible time and place of nuclear accidents and/or activities. Nationwide early warning system using aircraft and atmospheric dispersion model can help a nearly real-time forecasting and warning in preparation for radiological emergencies. (author)

    Nuclear installations are designed, constructed and operated in such a way that the probability for an incident or accident is very low and the probability for a severe accident with catastrophic consequences is extremely small. These accidents represent the residual risk of the nuclear installation, and this residual risk can be decreased on one hand by a better design, construction and operation and on the other hand by planning and taking emergency measures inside the facility and in the environment of the facility. By way of introduction and definition it may be indicated to define some terms pertaining to the subject in order to make for more uniform understanding. (orig./DG)

    Carter, Emma

    The Chernobyl accident brought to the fore the need for decision-making in nuclear emergency management to be transparent and consistent across Europe. A range of systems to support decision-making in future emergencies have since been developed, but, by and large, with little consultation with potential decision makers and limited understanding of the emergency management procedures across Europe and how they differ. In nuclear emergency management, coordination, communication and information sharing are of paramount importance. There are many key players with their own technical expertise, and several key activities occur in parallel, across different locations. Business process modelling can facilitate understanding through the representation of processes, aid transparency and structure the analysis, comparison and improvement of processes. This work has been conducted as part of a European Fifth Framework Programme project EVATECH, whose aim was to improve decision support methods, models and processes taking into account stakeholder expectations and concerns. It has involved the application of process modelling to document and compare the emergency management processes in four European countries. It has also involved a multidisciplinary approach taking a socio-technical perspective. The use of process modelling did indeed facilitate understanding and provided a common platform, which was not previously available, to consider emergency management processes. This thesis illustrates the structured analysis approach that process modelling enables. Firstly, through an individual analysis for the United Kingdom (UK) model that illustrated the potential benefits for a country. These are for training purposes, to build reflexive shared mental models, to aid coordination and for process improvement. Secondly, through a comparison of the processes in Belgium, Germany, Slovak Republic and the UK. In this comparison of the four processes we observed that the four process

    During the early phase of an emergency is necessary to confirm the release of radioactivity predictions made by the operator of the nuclear plant. In this context, it has begun measuring Ar-41 in the vicinity of a research reactor. Since the Ar-41 is produced in the reactor, it has been studied as a good way to validate the air dispersion model used in nuclear emergencies and to develop a method to improve the characterization of the release. For this latter purpose a pilot experiment was conducted to determine computational and experimental methods, the flux of 1.29 MeV of Ar-41 and compared to evaluate the accuracy of the assessments made. This paper describes meteorological forecasting systems used in the experiment, the estimate of the stability class and the concentration of nuclides using a calculation code developed by the ARN, as well as the methodology and equipment used for measurement in the field.

    The national emergency plan for nuclear accidents is a plan of action designed to provide a response to accidents involving the release or potential release of radioactive substances into the environment, which could give rise to radiation exposure to the public. The plan outlines the measures which are in place to assess and mitigate the effects of nuclear accidents which might pose a radiological hazard in ireland. It shows how accident management will operate, how technical information and monitoring data will be collected, how public information will be provided and what measures may be taken for the protection of the public in the short and long term. The plan can be integrated with the Department of Defence arrangements for wartime emergencies

    The Dutch organisation for nuclear emergency management has been described in previous papers. Briefly, the Ministry of Housing, Spatial Planning and Environment (VROM) and the Ministry of the Interior (BIZA) coordinate the input of all other Ministries and agencies at the government level, and provide the general strategy for dealing with the situation at hand. Any indication of a possible nuclear incident may alert the organization. Signals indicating, such incidents are continuously collected by the Emergency Management Department a VROM in the Hague. An expert group is permanently available for the evaluation of serious warnings, either via bilateral or other international contacts (IAEA, EC, neighbouring countries) or through the Dutch early warning monitoring network via the National Institute of Public Health and the Environment (RIVM). The chairman of this evaluation group has the authority to decide whether to start up the National Organization for Nuclear Emergency Management. Its start means the installation of a Policy Team of Cabinet Ministers or their representatives, and the involvement of many authorities and organizations at the national, provincial and local levels

    The filtered venting of the containment has been adopted in European countries to mitigate the consequences derived from the excess pressure of the containment during a severe accident. When venting has taken place, the fission products are released directly into the environment, unless a filter is placed in the path of the same, so various types of filters are used to trap the fission products. The containment venting filters currently installed use different filtering technologies that involve more than one medium. Those who use water as the first stage of filtration are called wet systems, are equipped with additional stages to eliminate water drops and emissions of fine aerosols, and may even be equipped with an element that contains certain means of absorption for the gaseous iodine species filtration. Other designs, based on deep bed filtration as the main retention stage, called dry filters; use metal fiber, ceramic or sand filtration media to trap aerosols. The present work evaluates the hydraulic characteristics of the sand bed type filter designed by EDF as a candidate to be installed in the containment of the BWR Mark II (primary containment type of the Laguna Verde nuclear power plant). The evaluation of the sand bed filter was performed using the OpenFOAM open source software package. Models of each zone of the filtering device were generated and by means of a series of parametric calculations of computational fluid mechanics, the relevant hydrodynamic characteristics of the device were obtained, such as pressure drops against mass flow and pressure fields and velocity under different operating conditions. On the other hand, the validation of the sand bed filter model was made when comparing the results of experimental tests carried out in a sand column of the PITEAS program (1985-1986) against the simulation in OpenFOAM. The results obtained are very close to those obtained experimentally. (Author)

    In all Nordic countries, nuclear emergency provisions have been revised following the Chernobyl accident. Local and national exercises are carried out regularly in each country. Several actions have been taken to harmonize the emergency approaches of the Nordic countries. In order to further promote consistent decisions in an emergency situation, two Nordic exercises were conducted in 1993. It was important to see if all five countries (Denmark, Finland, Iceland, Norway and Sweden) responded in a similar way to a given situation, as far as risk assessment and protective measures were concerned. The exercises were mainly aimed at decision makers and advisers of the five national emergency organizations. Thus, the exercises did not include comparison of underlying calculations on, e.g., atmospheric trajectories or transfer of radioactive material from air to ground. Such functions were tested separately in drills that also formed part of the Nordic emergency preparedness program. The exercises included an acute-phase situation (NORA), and a late-phase situation (ODIN). The Nordic exercises aroused international interest, and hence observers from IAEA, OECD/NEA and the European Union were invited to the exercises. NORA was observed by representatives from IAEA (in Finland) and OECD/NEA (in Sweden). ODIN was attended by IAEA (in Sweden) and the European Union (in Norway). Generally speaking, regional exercises such as NORA and ODIN help improve national emergency preparedness planning, organization and operations as well as international coordination. (EG)

    1982-01-01

    This Guide applies to nuclear power plants for which the total power supply comprises normal power supply (which is electric) and emergency power supply (which may be electric or a combination of electric and non-electric). In its present form the Guide provides general guidance for all types of emergency power systems (EPS) - electric and non-electric, and specific guidance (see Appendix A) on the design principles and the features of the emergency electric power system (EEPS). Future editions will include a second appendix giving specific guidance on non-electric power systems. Section 3 of this Safety Guide covers information on considerations that should be taken into account relative to the electric grid, the transmission lines, the on-site electrical supply system, and other alternative power sources, in order to provide high overall reliability of the power supply to the EPS. Since the nuclear power plant operator does not usually control off-site facilities, the discussion of methods of improving off-site reliability does not include requirements for facilities not under the operator's control. Sections 4 to 11 of this Guide provide information, recommendations and requirements that would apply to any emergency power system, be it electric or non-electric

    Korea Atomic Energy Research Institute (KAERI) is carrying out the project 'Development of Core Technology for Remote Response in Nuclear Emergency Situation', and as a part of the project, we are studying the reliability and performance requirements of nuclear emergency response robots. In this paper, we described some qualitative requirements for testing of nuclear emergency response robots which are different to general emergency response robots. We briefly introduced test requirements of general emergency response robots and described some qualitative aspects of test requirements for nuclear emergency response robots. When considering an immature field-robot technology and variety of nuclear emergency situations, it seems hard to establish quantitative test requirements of these robots at this time. However, based on studies of nuclear severe accidents and the experience of Fukushima NPP accident, we can expect some test requirements including quantitative ones for nuclear emergency response robots

    As an ex-chief of affected town of Fukushima nuclear disaster, basic ideas were enumerated as no more accident occurring, necessity of early evacuation, all budget and right belonging to end administrator, appropriate response of government's emergency countermeasure headquarter on proposal of end administrator, failure of evacuation lead coming from government's information concealment, no more secondary damage of affected refuge, public disclosure of information, safety as the top priority with no compromise or preferred profit, new mechanism of resident's direct participation in preventing accidents, and fair review system of inspection based on checklist. Nuclear-related regulatory organizations and electric utilities should be reformed as open and transparent organization and responsible for following results of accidents. Public trust on government was completely lost after the Fukushima nuclear disaster and people should not rely on some organizations and be respective expert and foster self-defense capability so as to establish government by the people.

    Off-site nuclear emergency response in Germany is divided into disaster response under the responsibility of the Laender and measures for precautionary radiation protection pursuant to the Precautionary Radiation Protection Act under the lead of federal authorities. Early countermeasures at the regional level require a different management than long-term and comprehensive actions of precautionary radiation protection. As situations may arise in which measures of both approaches overlap with regard to place and time, it is essential to make thorough preparations in order to avoid problems with implementation.

    Ikehara, Morihiko.

    1981-01-01

    Purpose: To increase the reliability of a nuclear reactor by allowing an emergency facility to be manually started and stopped to make its operation more convenient and eliminate the possibility of erroneous operation in an emergency. Constitution: There are provided a first water level detector for detecting a level lower than the first low water level in a reactor container and a second water level detector for detecting a level lower than the second low water level lower than the first low water level, and an emergency facility can be started and stopped manually only when the level is higher than the second low water level, but the facility will be started regardless of the state of the manual operation when the level is lower than the second low water level. Thus, the emergency facility can be started by manual operation, but will be automatically started so as to secure the necessary minimum operation if the level becomes lower than the second low water level and the stopping operation thereafter is forgotten.

    The main objectives of the current EU project 'Integrated Systems for Forecasting Urban Meteorology, Air Pollution and Population Exposure' (FUMAPEX) are the improvement of meteorological forecasts for urban areas, the connection of numerical weather prediction (NWP) models to urban air pollution and population dose models, the building of improved urban air quality information and forecasting systems, and their application in cities in various European climates. In addition to the forecast of the worst air-pollution episodes in large cities, the potential use of improved weather forecasts for nuclear emergency management in urban areas, in case of hazardous releases from nuclear accidents or terror acts, is considered. Such use of NWP data is tested for the Copenhagen metropolitan area and the Oresund region. The Danish Meteorological Institute (DMI) is running an experimental version of the HIRLAM NWP model over Zealand including the Copenhagen metropolitan area with a horizontal resolution of 1.4 km, thus approaching the city-scale. This involves 1-km resolution physiographic data with implications for the urban surface parameters, e.g. surface fluxes, roughness length and albedo. For the city of Copenhagen, the enhanced high-resolution NWP forecasting will be provided to demonstrate the improved dispersion forecasting capabilities of the Danish nuclear emergency preparedness decision-support system, the Accident Reporting and Guidance Operational System (ARGOS), used by the Danish Emergency Management Agency (DEMA). Recently, ARGOS has been extended with a capability of real-time calculation of regional-scale atmospheric dispersion of radioactive material from accidental releases. This is effectuated through on-line interfacing with the Danish Emergency Response Model of the Atmosphere (DERMA), which is run at DMI. For local-scale modelling of atmospheric dispersion, ARGOS utilises the Local-Scale Model Chain (LSMC), which makes use of high-resolution DMI

    The emergency rescue operation on major accident of nuclear facilities contains four kinds of abilities that are command and control, radiation protection, radiation monitoring and radioactive decontamination, so it needs to organize some equipment of nuclear emergency to enhance the efficiency of nuclear emergency operation. The organization of equipment of nuclear emergency should accord to the reality of the development in our country. It should have extractive structure, brief variety and advance capability, and also should be convenient, useful and adequate. The method of organization can first accord to the organization of group and organize the facilities accord to the organization of group of the emergency rescue force. (authors)

    On the basis of establishing the multi-layer structure of nuclear accident emergency decision, several decision objectives are synthetically analyzed, and an optimization model of decision proposals for nuclear accident emergency based on interval analytic hierarchy process is proposed in the paper. The model makes comparisons among several emergency decision proposals quantified, and the optimum proposal is selected out, which solved the uncertain and fuzzy decision problem of judgments by experts' experiences in nuclear accidents emergency decision. Case study shows that the optimization result is much more reasonable, objective and reliable than subjective judgments, and it could be decision references for nuclear accident emergency. (authors)

    The Radiological Emergency Preparedness (REP) Program was created after the March 1979 accident at the Three Mile Island nuclear power station. The Federal Emergency Management Agency (FEMA) assists state and local governments in reviewing and evaluating state and local REP plans and preparedness for accidents at nuclear power plants, in partnership with the US Nuclear Regulatory Commission (NRC), which evaluates safety and emergency preparedness at the power stations themselves. Argonne National Laboratory provides support and technical assistance to FEMA in evaluating nuclear power plant emergency response exercises, radiological emergency plans, and preparedness

    The design of nuclear facilities is to exclude serious damage to the environment, even in case of the MCA (maximum credible accident). Although the likelihood of accidents exceeding the expected consequences of the MCA is extremely small, it is deemed reasonable to take general precautions against such accidents. Precautions of this type are customary also in the conventional field, and in this case they are to be implemented in part through the Nuclear Emergency Assistance Team. If the internal safety provisions of a nuclear facility are unable to prevent an impermissible leakage of radioactivity as the result of a major accident there is, at present, no possibility of decisively curbing the spread of activity throughout the environment in the first few hours after the accident. Hence the measures taken by the authorities as a result of the emission and immediately following upon it will have to be restricted to the protection of the population: analysis of intensity and pattern of distribution of activity, instructions.to seek closed shelters, or prohibition of the consumption of certain foodstuffs, distribution of blocking agents, etc. It is the purpose of the Nuclear Emergency Assistance Team to bring relief in the phase following the end of the emission. This may comprise the following steps: exact investigation of the external scope of the damage, in particular assessment of the contamination of ground, persons, and material; rapid personnel decontamination; securing and shielding radiation sources; fixing contamination and removing it immediately where this is deemed urgent for reasons of traffic or to keep the drinking water free from contamination; external containment of the source of danger; support in limiting the damage within the facility. In addition to these tasks of emergency protection, the Nuclear Emergency Assistance Team can take action also in disturbances within the facility which have no influence on the environment and where the operator

    Full text: Urgent protective measures for the possibly affected population are the main items to be addressed here, that means actions to be planned and taken in the pre-release and release phase of a nuclear accident. Since we will focus an off-site nuclear emergency management, the utility or licensee only plays a subordinate role, but nevertheless may be the potential cause of all actions. At the other end, there is the possible affected population, the environment, and also economic values. Emergency preparedness and response aims at minimizing adverse effects from the power plant to the values to protect. In the early phase of an accident under consideration here, prompt and sharp actions are necessary to ensure efficacy. On the other hand, the available information on the situation is most limited in this phase such that pre-determined actions based on simple criteria are indispensable. The responsibility for early response actions normally rest with a regional authority which may have some county administrations at subordinate level. The leader of the regional staff has to decide upon protective measures to be implemented at county or municipal level; thus, coherence of the response is ensured at least at a regional level. The decision will be governed at the one side by the existing or predicted radiological situation, on the other side an practical limitations like availability of teams and means. The radiological situation has to be assessed by an advisory team that compiles all information from the utility, the weather conditions, and monitoring results. While the staff leader is experienced through response to major non-nuclear events, the advisors mainly come from the environmental side, having no experience in taking swift decisions in an emergency, but are used to control and prevent. This might be the source of conflicts as observed in several exercises. The radiation protection advisors collect information from the utility, especially about time

    After Three Mile Island, Arkansas Nuclear One produced a planning document called TMI-2 Response Program. Phase I of the program defined action plans in nine areas: safety assessment, training, organization, public information, communication, security, fiscal-governmental, technical and logistical support. Under safety assessment, the staff was made even better prepared to handle radioactive material. Under training, on site simulators for each unit at ANO were installed. The other seven topics interface closely with each other. An emergency control center is diagrammed. A habitable technical support system was created. A media center, with a large media area, and an auditorium, was built. Electric door strike systems increased security. Phone networks independently run via microwave were installed. Until Three Mile Island, logistical problems were guesswork. That incident afforded an opportunity to better identify and prepare for these problems

    Ever since Plaben came into force in 1989, the national civil protection system has experienced a large evolution among other reasons due to the Autonomous Community governments assuming authority in this matter. In parallel, the regulation and international practice in matters of planning and nuclear emergency response has evolved as a consequence of the lessons learned following the long-term Chernobyl accident. Both circumstance recommended that Plaben be revised in order to adopt it to this new environment. The New Plaben was approved in June of this year and from that moment implantation has begun. Described in the article is the New Plaben, the modifications that respect the former the role that the CSN played in is revision and the main activities required to put it into practice. (Author)

    The first stage of world nuclear power development based on light water fission reactors has demonstrated not only rather high rate but at the same time too optimistic attitude to safety problems. Large accidents at Three Mile Island and Chernobyl essentially affects the concept of NP development. As a result the safety and social acceptance of NP became of absolute priority among other problems. That's why emerging nuclear power systems should be first of all estimated from this point of view. In the paper some quantitative criteria of safety derived from estimations of social risk and economic-ecological damage from hypothetical accidents are formulated. On the base of these criteria we define two stages of possible way to meet safety demands: first--development of high safety fission reactors and second--that of asymptotic high safety ENEs. The limits of tolorated expenses for safety are regarded. The basis physical factors determining hazards of NES accidents are considered. This permits to classify the ways of safety demands fulfillment due to physical principals used

    Due to high safety standards at nuclear power plants, no experience exits with nuclear emergencies in Western Europe. Thus, emergency exercises are the only possibility to assure effective protective measures should the very unlikely severe accident occur. The main objectives of exercises are generally the check of response plans for suitability, the test of the equipment's applicability and training of personnel for the unusual task to manage a nuclear emergency. After an introduction into the different types of exercises, this contribution focuses on offsite nuclear emergency exercises, explaining frame conditions to ensure good practice and, finally, reports some experience from exercises.

    The project focuses on the review of IAEA documentation on nuclear or radiological emergencies with main focus on methodology for developing and arrangement for nuclear and radiological emergencies. The main objective of this work is to identify limitations in IAEA documentation on emergency preparedness and response (EPR) and provide recommendation on the main actions needed to fill the gaps identified thus aiding in improvement of emergency preparedness and response to nuclear and radiological accidents. The review of IAEA documentation on nuclear and radiological emergency has been carried out by evaluating various emergency response elements. Several elements for EPR were highlighted covering the safety fundamentals, general safety requirements and EPR methods for development of an effective emergence response capability for nuclear or radiological emergencies. From these issues, the limitations of IAEA documentation on EPR were drawn and recommendations suggested as a means of improving EPR methods. Among them was the need for IAEA consider establishment of follow up and inspection programmes to facilitate implementation of EPR requirements in most developing countries, establishment of programmes that provide platforms for the countries to be motivated to update their system in line with the current status of emergency preparedness, review of the international information exchange aspects of nuclear emergencies in order to improve capabilities to communicate reliable data, information and decisions quickly and effectively among national authorities and their emergency and emergency response centres.

    Large effort has been taken for nuclear emergency programs in Japan especially after the JCO accident. A special law for nuclear emergency was established after the accident. The law extended the scope of emergency preparedness to fuel cycle facilities, research reactors, etc. and clarified the roles and responsibilities of the national government, local governments and license holders. For initial responses, the action levels and action procedures are defined based on environmental doses and specific initial events of NPPs. A senior specialist was dispatched to each site for nuclear emergency and a facility 'Off-site center' to be used as the local emergency headquator was designated at each site. This paper describes the structure of emergency program, responsibility of related organizations and the definition of unusual events for notification and emergency. Emergency preparedness, emergency radiation monitoring and computer-based prediction of on- and off-site situation are also addressed. (author)

Meanwhile, there also exist some management problems such as repeated investment, fragmented inventory list, inefficient management, etc. To achieve integrated management on the nuclear emergency resources of China, the Chinese government initiated the project “The Information Management Platform on Nuclear Emergency Resources of China”. The goal of the project is to support a timely, managed, controlled, coordinated and effective response while the resources managing process remains economically efficient. The project team firstly completed the nuclear emergency resources classification and encoding. Based on these, the nuclear emergency resources information management software system was developed. The pilot operation in the system was carried out both in Guangxi and Liaoning Province at the same time. Nuclear emergency resources survey was done as the relevant information was put into the database in these regions. The evaluation result on the pilot operation showed that, the information management platform on emergency resources would apparently improve efficiency of nuclear emergency preparedness and response, and it also would increase economical efficiency on inventory list, information management and invest decision.

    This document has the purpose of to share acquired experiences during the implementation of the Coaching project focused the training of supervisors and directive personnel of the nuclear power plant of Laguna Verde (NPP-L V). Derived of the improvement areas identified by the supervisor organization of the nuclear power stations WANO (World Association Nuclear of Operators) and of the auto-evaluations realized by the expert personnel of the same power station that based on external experiences carried out through the Benchmarking (comparison with other power stations) they have reflected the necessity to activate a training process in Coaching with a practical focus toward the directive and supervisor personnel in the power station. By means of the observation of the personnel's acting so much in the control rooms like in different areas, three focus areas have been identified for the training in Coaching, these are the personnel's motivation, the organizational communication so much in vertical form as horizontal and the perception of confidence lack among directive, supervisors, operators and technicians. The plan focused in the abilities training of Coaching with practical sense was development, supported with an evaluation of 360 grades as tool of competitions development through a computer application e-Coaching. The use of application and Coaching following techniques facilitated the conformation of the practical focus, same that are of continuous use starting from the training of the supervisor and directive personnel.

    The present study entitled ''Emergency Response and Nuclear Risk Governance: nuclear safety at nuclear power plant accidents'' deals with issues of the protection of the population and the environment against hazardous radiation (the hazards of nuclear energy) and the harmful effects of radioactivity during nuclear power plant accidents. The aim of this study is to contribute to both the identification and remediation of shortcomings and deficits in the management of severe nuclear accidents like those that occurred at Chernobyl in 1986 and at Fukushima in 2011 as well as to the improvement and harmonization of plans and measures taken on an international level in nuclear emergency management. This thesis is divided into a theoretical part and an empirical part. The theoretical part focuses on embedding the subject in a specifically global governance concept, which includes, as far as Nuclear Risk Governance is concerned, the global governance of nuclear risks. Due to their characteristic features the following governance concepts can be assigned to these risks: Nuclear Safety Governance is related to safety, Nuclear Security Governance to security and NonProliferation Governance to safeguards. The subject of investigation of the present study is as a special case of the Nuclear Safety Governance, the Nuclear Emergency governance, which refers to off-site emergency response. The global impact of nuclear accidents and the concepts of security, safety culture and residual risk are contemplated in this context. The findings (accident sequences, their consequences and implications) from the analyses of two reactor accidents prior to Fukushima (Three Mile Iceland in 1979, Chernobyl in 1986) are examined from a historical analytical perspective and the state of the Nuclear Emergency governance and international cooperation aimed at improving nuclear safety after Chernobyl is portrayed by discussing, among other topics, examples of &apos

    Nuclear power is a safe, clean energy, which has been evidenced by the history of nuclear power development. Nuclear power is associated with very low risk but not equal to zero. Accident emergency response and preparedness is a final barrier necessary to reduce potential risks that may arise from nuclear power plants, which must be enhanced. In the course of accident emergency response and preparedness, it is highly necessary to draw domestic and foreign experiences and lessons. Lastly, the paper presents the discussions of some issues which merit attention with respect to emergency response and preparedness in China. (authors)

    Lewis A. Dunn, a former Assistant Director of the US Arms Control and Disarmament Agency and now a senior analyst with Science Applications International Corporation, looks to the future to offer "The Emerging Nuclear Suppliers: Some Guidelines for Policy ." Mr. Dunn notes that although most emerging suppliers are cautious, many are not party to existing nonproliferation treaties. He calls upon the nonproliferation community to continue the present policy of not supporting unsafeguarded nuclear activities. He suggests that the nonproliferation community work within existing standards and infrastructures of nuclear suppliers to convince emerging supplier nations of the merits of nuclear export control.

    1976-01-01

    Upon the occasion of loss of coolant in a nuclear reactor as when a coolant supply or return line breaks, or both lines break, borated liquid coolant from an emergency source is supplied in an amount to absorb heat being generated in the reactor even after the control rods have been inserted. The liquid coolant flows from pressurized storage vessels outside the reactor to an internal manifold from which it is distributed to unused control rod guide thimbles in the reactor fuel assemblies. Since the guide thimbles are mounted at predetermined positions relative to heat generating fuel elements in the fuel assemblies, holes bored at selected locations in the guide thimble walls, sprays the coolant against the reactor fuel elements which continue to dissipate heat but at a reduced level. The cooling water evaporates upon contacting the fuel rods thereby removing the maximum amount of heat (970 BTU per pound of water) and after heat absorption will leave the reactor in the form of steam through the break which is the cause of the accident to help assure immediate core cooldown

    This work was performed in order to plan countermeasures that, after an accidental release of radioactivity, could reduce the dose to the public due to the consumption of contaminated milk and milk products. The attention was focused on whether there are justified and optimised actions below the international recommended concentration levels in foodstuffs. The analysis was conducted as a case study, i.e., it was assumed that a hypothetical accident had happened in a nuclear power plant leading to a release of radionuclides which severely contaminated a wide area of Ostrobothnia, one of Finland's most important milk production areas. The dose averted by actions, the' monetary costs and the feasibility of actions were assessed. It was also studied what information is needed by decision-makers and in which form this information should be presented. Finally, it was examined how planning of countermeasures could be enhanced by applying decision analysis in establishing actions strategies and valuing attributes considered in decision making. Preparative meetings and a concluding workshop was arranged and all authorities involved in food-related emergency management were invited to jointly analyse different options. According to the query made the participants considered the decision workshop and decision analysis very practicable in exercises. The exercise as a whole was also evaluated useful or very useful. The presented techniques in a real situation were considered applicable but not as useful as in exercises. Thus it can be deduced that the concluding workshop and decision analysis interviews augment well conventional emergency exercises. Realistic dose assessments proved out to be very difficult. The software used was able to calculate the maximum radionuclide concentrations in foodstuffs processed from local raw materials. Radionuclide concentration in food or feedstuffs may, however, change quickly. Also, the production and processing of foodstuffs is a complex

    All nuclear facilities in Indonesia are owned and operated by the National Nuclear Energy Agency (BATAN). The programs and activities of emergency planning and preparedness in Indonesia are based on the existing nuclear facilities, i.e. research reactors, research reactor fuel fabrication plant, radioactive waste treatment installation and radioisotopes production installation. The assessment is conducted to learn of status of emergency preparedness and response plan for nuclear facilities in Indonesia and to support the preparation of future Nuclear Power Plant. The assessment is conducted by comparing the emergency preparedness and response system in Indonesia to the system in other countries such as Japan and Republic of Korea, since the countries have many Nuclear Power Plants and other nuclear facilities. As a result, emergency preparedness response plan for existing nuclear facility in Indonesia has been implemented in many activities such as environmental monitoring program, facility monitoring equipment, and the continuous exercise of emergency preparedness and response. However, the implementation need law enforcement for imposing the responsibility of the coordinators in National Emergency Preparedness Plan. It also needs some additional technical support systems which refer to the system in Japan or Republic of Korea. The systems must be completed with some real time monitors which will support the emergency preparedness and response organization. The system should be built in NPP site before the first NPP will be operated. The system should be connected to an Off Site Emergency Center under coordination of BAPETEN as the regulatory body which has responsibility to control of nuclear energy in Indonesia. (Author)

    The OECD Nuclear Energy Agency has a long tradition of expertise in the area of nuclear emergency policy, planning, preparedness and management. Through its activities in this field, the Agency offers its member countries unbiased assistance on nuclear preparedness matters, with a view to facilitating improvements in nuclear emergency preparedness strategies and response at the international level. The 1986 Chernobyl accident demonstrated that nuclear accidents can have international consequences, highlighting the need for international co-operation, and leading to improvements in the areas of international communication, information exchange and harmonization of response actions between countries. From its inception, the NEA Working Party on Nuclear Emergency Matters has focused on improving the effectiveness of international nuclear emergency preparedness and management. Part of its work programme is set on exploring and developing new concepts and future procedures to enhance national and international preparedness and response management. A central approach to this has been the preparation and conduct of the International Nuclear Emergency Exercise (INEX) series. The role and strategies of exercises and future directions are discussed in this presentation. (A.L.B.)

    Radiation emergency preparedness systems must be able to deal with the threats posed to each country and the region as a whole. The threats from nuclear accidents differ in the various countries of the region. The most serious nuclear threats are those with cross-border implications and are generally assumed to be due to the presence of nuclear reactors of various kinds. Some countries in the region, Finland, Germany, Lithuania, the Russian Federation and Sweden, have nuclear power plants, and several countries in the region possess smaller research reactors. Other nuclear threats arise from nuclear powered naval vessels or submarines, and from nuclear powered satellites. Production, transportation, use, and disposal of radioactive materials constitute potential local nuclear hazards. Finally, terrorist use of radioactive material poses a nuclear threat to all countries. (au)

    Severe accidents at nuclear power plant have led to significant consequences to the people, the environment or the facility. Therefore, the appropriate response is required for the mitigation of the accidents. In the past, most of responses were performed by human beings, but it was dangerous and risky. In this paper, we proposed unmanned mobile system for the monitoring of nuclear accident in order to response effectively. For the integrity of reactor cooling and containment building, reactor cooling pipe and hydrogen distribution monitoring with unmanned ground vehicle was designed. And, for the safety of workers, radiation distribution monitoring with unmanned aerial vehicle was designed. Unmanned mobile monitoring system was proposed to respond nuclear accidents effectively. Concept of reinforcing the integrity of RCS and containment building, and radiation distribution monitoring were described. RCS flow measuring, hydrogen distribution measuring and radiation monitoring deployed at unmanned vehicle were proposed. These systems could be a method for the preparedness of effective response of nuclear accidents.

    Future nuclear energy systems may achieve substantially lower energy costs than those of existing fossil energy systems and comparable capital costs. Such low cost nuclear energy would provide a strong economic incentive to minimize the use of fossil fuels. If these low cost nuclear energy systems emerge in the next few decades, 21st century civilization may be able to avert potentially disastrous CO 2 induced global climate changes. 12 refs., 1 fig

    Full text: Current nuclear emergency management procedures do not always satisfactorily address issues related to the information availability and to how people in emergency control centres use this information to respond to an nuclear accident. The lack of an adequate and prompt information may lead to a response that can be very different from what authorities recommend and thus create confusion, mistrust, and widespread uncertainty. This is a potentially serious problem for emergency planners. An adequate and prompt access to relevant information is a critical requirement that emergency teams face while they work towards reducing the undesired consequences of the emergency. There are three basic types of knowledge according to a conceptual framework developed to deal with emergency response: Previous Personal, Previous and, Current Contextual knowledge. Most decisions in emergency control centres require a dynamic combination of all types of knowledge, particularly the current contextual that comes from the emergency settings, including all information about the activities of other emergency teams. The aim of this paper is to describe the concepts and the structure of a system that aims at storing and disseminating the previous formal and contextual knowledge to help teams make the correct decisions during the evolution of an emergency. The elicitation of critical requirements are provided by a case study based on Cognitive Work Analysis and Naturalistic Decision Making methods, applied to a nuclear emergency response simulation. The framework and a prototype system were tested in a controlled experiment. The paper reports the results of this experiment. (author)

    The Nuclear Safety Working Group (NSWG) of the Pacific Basin Nuclear Cooperation Committee initiated cooperation among Pacific Basin areas based primarily around emergency planning. The NSWG conducted a review of the emergency response plans of members. This paper briefly reviews and makes a comparison of the emergency response plans, with particular attention on the response organization, the planning zone, and the protective action guidelines for emergencies. Although all areas have adopted the same basic elements of emergency planning and are similar, there are also variances due to different governmental structures, population densities, and available resources. It is found that the most significant difference is in the size of the emergency planning zone. The paper concludes with a discussion on possible future cooperative activities of the working group.

    2004-01-01

    The 1986 tragedy at the Chernobyl Nuclear Power Plant in Ukraine motivated the entire international nuclear community to ensure that countries would, in the future, be well prepared to manage the physical, psychological and financial consequences of a serious nuclear accident. Since that event, numerous nuclear emergency preparedness and post-emergency management programmes have been established at national and international levels to ensure that appropriate mechanisms will respond to the threat, and the aftermath, of a nuclear accident. The INEX 2000 Workshop on the Indemnification of Nuclear Damage, jointly organised by the OECD/Nuclear Energy Agency and the French Government, was the first ever international programme to address the manner in which victims of a nuclear accident with trans-boundary consequences would be compensated for damage suffered before, during and after the accident. The Workshop results revealed striking differences in the compensation principles and practices implemented in the 30 participating countries, in the co-ordination measures between different public authorities within an affected state, and in the co-operative procedures between the accident state and its neighbours. All participants agreed on the need for improvement in these areas, particularly for maintaining public confidence in governments' ability to properly manage nuclear emergencies

    Significant changes have occurred in recent years in the nuclear power industry to accentuate the need for data systems to support information flow and decision making. Economic conditions resulting in rapid inflation and larger investments in new and existing plants and the need to plan further ahead are primary factors. Government policies concerning environmental control, as well as minimizing risk to the public through increased nuclear safety regulations on operating plants are additional factors. The impact of computer technology on plant data systems, evolution of corporate and plant infrastructures, future plant data, system designs and benefits, and decision making capabilities and data usage support are discussed.

    Nuclear emergency planning and preparedness in Japan have been organized by both national and local governments based on the Disaster Countermeasures Basic Act. Off-site nuclear emergency exercises are classified into two types: national-government level exercises and local-government level exercises. National-government level exercises are carried out once a year by the competent national authorities. Among these authorities, the Science and Technology Agency (STA) fills a leading position in the Japanese nuclear emergency planning and preparedness. Local-government level exercises are carried out once a year or once in a few years by the local governments of the prefectures where nuclear facilities are located. Most of the off-site nuclear emergency exercises in Japan are performed by local-governments. The aim of these exercises is to reinforce the skills of the emergency staff. The national government (STA etc.) provides advices and assistance including financial support to the local-governments. Emergency exercises with the participation of residents have been carried out in some local-governments. As an example of local-government level exercises, an experience in Shizuoka prefecture (central part of Japan) is presented

    From 2003, the Nuclear Regulatory Authority (RNA) has worked in the implementation of a Geographical Information System (SIG) for the planning and the intervention in emergencies, with special emphasis in the nuclear emergencies. The main objective of the SIG developed in the ARN is to give the necessary support for the planning, training and application of the actions of radiological protection necessary in front of a nuclear emergency, offering the geo referenced cartographic base, the readiness of logistical resources in the whole country, incorporating results of models of forecast of consequences and environmental measurements during the emergency, facilitating the analysis of this information in real time and facilitating the presentation of results for the decision making. The cartographic base is constituted of demographic, social, economic data identification of main actors interveners in the emergency, vial infrastructure and natural characteristics of the area in question. In this work the main characteristics of the implemented SIG are presented including the conceptual standards of design that contemplate the international requirements for the planning and answer in the event of nuclear emergencies, the current state of the system and the foreseen evolution. A description of the opposing problems during its implementation that can be common to many countries of the region is also presented, as well as the obtained experience of its use in preparation tasks for emergencies and in mocks.

    Yamamoto, Kazuya

    2007-10-01

    The International Atomic Energy Agency (IAEA) has introduced new concepts of precautionary action zone (PAZ) and urgent protective action planning zone (UPZ) in 'Preparedness and Response for a Nuclear or Radiological Emergency' (GS-R-2 (2002)), in order to reduce substantially the risk of severe deterministic health effects. Open literature based research was made to reveal problems on evacuation planning and the preparedness for nuclear emergency arising from introduction of PAZ into Japan that has applied the emergency planning zone (EPZ) concept currently. In regard to application of PAZ, it should be noted that the requirements for preparedness and response for a nuclear or radiological emergency are not only dimensional but also timely. The principal issue is implementation of evacuation of precautionary decided area within several hours. The logic of evacuation planning for a nuclear emergency and the methods of advance public education and information in the U.S. is effective for even prompt evacuation to the outside of the EPZ. As concerns evacuation planning for a nuclear emergency in Japan, several important issues to be considered were found, that is, selection of public reception centers which are outside area of the EPZ, an unique reception center assigned to each emergency response planning area, public education and information of practical details about the evacuation plan in advance, and necessity of the evacuation time estimates. To establish a practical evacuation planning guide for nuclear emergencies, further researches on application of traffic simulation technology to evacuation time estimates and on knowledge of actual evacuation experience in natural disasters and chemical plant accidents are required.

    The political and economic upheavals which have taken place in Eastern Europe have had an impact on radiation and nuclear safety throughout Europe. Emergency preparedness systems for unexpected nuclear events have been developed further in all European countries, and prosperous western nations have invested in improving the safety of East European nuclear power plants. The economic crisis facing countries of the former Soviet Union has also promoted illicit trade in nuclear materials; this has made it necessary for various border guards and police authorities to intensify their collaboration and to tighten border controls. On 3-4 October 1995, Finnish Centre for Radiation and Nuclear Safety (STUK) arranged a seminar on nuclear threats and emergency preparedness in Finland. In addition to STUK experts, a wide range of rescue and civil defence authorities, environmental health specialists and other persons engaged in emergency preparedness attended the seminar. The publication contains a compilation of reports presented at the seminar. The reports cover a broad spectrum of nuclear threats analyzed at STUK, the impacts of radioactive fallout on human beings and on the environment, and preparedness systems by which the harmful effects of radiation or nuclear accidents can, if necessary, be minimized.

    The objective of this study was to develop an emergency database search system for nuclear power plants during nuclear incidents / accidents. Image data reported from nuclear power plants to the regulatory body and other related data will be stored systematically in the computer. The data will be utilized during nuclear emergency to prevent the accident from spreading out and to minimize its effect. It will also be used in exchanging information on accident or incidents with the foreign countries. The operational documents in the Kori-4 nuclear power plant are used as the major source for the categorization and analysis in performing this research. It was not easy to access the detailed operational data due to its unique characteric for the security. Therefore, we strongly suggest to increase manpower for this project in Korea Institute of Nuclear Safety (KINS) and archive involvement from Korea Electric Power Company to establish better database retrieval system

    Full text: After the Chernobyl accident a national emergency plan of protective measures for radiological emergencies has been set up in Italy to cope with nuclear risks which require actions at national level. Since most of the Italian nuclear installations are, at present, not operational, the most relevant nuclear risk sources identified in the national emergency plan stem from accidents in nuclear power plants near the Italian borders or aboard nuclearpropelled ships, or events related to the fall of nuclear-powered satellites and transportation of radioactive materials. The plan identifies a reference scenario for nation-wide emergency interventions and the proper structures to be involved in the radiological emergency. However, risks related to nuclear terrorism are not taken into account in the plan, whereas nuclear plants as well as nuclear materials and sources (in use in medical, scientific and industrial applications) are known to represent potential targets for hostile acts, potentially giving rise to harmful radioactive releases into the atmosphere. Along with four nuclear power plants, now undergoing a decommissioning procedure, several other nuclear facilities, such as provisional radioactive waste deposits or research centers, are present in Italy. Unfortunately not all of the radioactive waste inventory is conditioned in such a way to make a spread of radioactive contamination, as a consequence of a hostile action, unlikely; moreover, spent fuel elements are still kept, in some cases, inside the plant spent fuel storage pool. In this paper the hypothetical radiological impact of deliberate actions against some reference nuclear installations will be evaluated, together with its amplications for an appropriate profiling of the emergency countermeasures which could be required. Especially the case of a terrorism act against a spent fuel storage pool is worked out in some detail, as this event appears to be one of those with the most severe

    The nuclear power plants in India adopts a high level of defence in depth concept in design and operates at highest degree of safety, however the possibility of nuclear accidents cannot be ruled out. The safety and regulatory review of Nuclear Power Plants (NPPs) in India are carried out by Atomic Energy Regulatory Board (AERB). Section 33 of Atomic Energy (Radiation Protection) Rules-2004 provides the basic requirements of emergency preparedness aspects for a nuclear facility. Prior to the issuance of a license for the operation of NPPs, AERB ensures that the site specific emergency response manuals are in place and tested. The emergency response plan includes the emergency response organization, their responsibilities, the detailed scheme of emergency preparedness, response, facilities, equipments, coordination and support of various organizations and other technical aspects. These emergency preparedness plans are tested at periodic interval to check the overall effectiveness. The plant and site emergency exercise is handled by the plant authorities as per the site emergency plan. The events with off-site consequences are handled by the district authorities according to the off-site emergency plan. In off-site emergency exercises, observers from AERB and other associated organizations participate. Observations of the participants are discussed in the feedback session of the exercise for their disposition. This paper reviews the current level of emergency planning and preparedness, statistics of emergency exercises conducted and their salient findings. The paper highlights improvement in the emergency management programme over the years including development of advance technical support systems. The major challenges in off-site emergency management programme such as industrial growth and increase in population within the sterilized zone, frequent transfer of district officials and the floating population around the NPPs are outlined. The areas for improvement in

    Emergency preparedness and response arrangements at Nuclear Power Plants (NPPs) in Pakistan have been reevaluated in the light of Fukushima Daiichi accident. Appropriate measures have been taken to strengthen and effectively implement the on-site and off-site emergency plans. Verification of these plans is conducted through regulatory review and by witnessing periodic emergency drills and exercises conducted by the NPPs in the fulfilment of the regulatory requirements. Emergency Planning Zones (EPZs) have been revised at NPPs. A multi discipline reserve force has been formed for assistance during severe accidents. Nuclear Emergency Management System (NEMS) has been established at the national level in order to make necessary arrangements for responding to nuclear and radiological emergencies. Training programs for first responders and medical professionals have been launched. Emergencies coordination centres have been established at national and corporate levels. Public awareness program has been initiated to ensure that the surrounding population is provided with appropriate information on emergency planning and response. To share national and international operational experience, Pakistan has arranged various workshops and developed a strong link with International Atomic Energy Agency (IAEA). (author)

    Nuclear disaster prevention is fundamentally preparedness for emergency with extremely lower forming probability. In order to establish allowance of nuclear energy application from society, it is essential that it brings relief feelings with preparedness and without anxiety among everything. At a time when use of nuclear energy was begun, a consciousness that a nuclear facility was one highly considered on its safety faster than that in the other industries was large and intense, and then recognition of necessity for nuclear disaster prevention was extremely minute. However, the nuclear emergency of critical accident at the JCO fuel processing facility in Tokai-mura formed on September 30, 1999 gave Japanese extremely large impact so as fundamentally to change actual feelings against conventional nuclear disaster prevention. Here was introduced on efforts onto reinforcement of nuclear disaster prevention together with establishment of the special measure rule nuclear disaster prevention countermeasure as well as its advantages and progress, to investigate on a subject to do it for a preparedness with effectiveness for obtaining real safe feelings.

    International Nuclear Information System (INIS)

    2014-01-01

    Safety is one of the most important considerations when engaging in highly advanced scientific and technological activities. In this respect, utilizing the potential of nuclear technology for peaceful purposes also involves risks, and nuclear techniques themselves can be useful in strengthening emergency response measures related to the use of nuclear technology. In the case of a nuclear incident, the rapid measurement and subsequent monitoring of radiation levels are top priorities as they help to determine the degree of risk faced by emergency responders and the general public. Instruments for the remote measurement of radioactivity are particularly important when there are potential health risks associated with entering areas with elevated radiation levels. The Nuclear Science and Instrumentation Laboratory (NSIL) — one of the eight laboratories of the Department of Nuclear Sciences and Applications (NA) in Seibersdorf, Austria — focuses on developing a variety of specialized analytical and diagnostic instruments and methods, and transferring knowledge to IAEA Member States. These include instruments capable of carrying out remote measurements. This emergency response work carried out by the NA laboratories supports health and safety in Member States and supports the IAEA’s mandate to promote the safe and peaceful use of nuclear energy

    The safety parameter employed for emergency scrams of a liquid metal cooled reactor is the coolant pressure. An actuation bellows is provided which is connected to a measuring chamber by means of a flow system. Both units are installed in a coolant flow section. The measuring chamber proper is connected with the coolant by means of an aperture limiting the flow. Inside the measuring chamber there is an expansion space filled with gas. Pressure changes in the coolant affect the pressure in the expansion space. Expansion of the bellows actuates the release mechanism. (DG) [de

  5. Generic procedures for medical response during a nuclear or radiological emergency. Emergency preparedness and response

    International Nuclear Information System (INIS)

    2005-04-01

    The aim of this publication is to serve as a practical resource for planning the medical response to a nuclear or radiological emergency. It fulfils in part functions assigned to the IAEA under Article 5.a(ii) of the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), namely, to collect and disseminate to States Parties and Member States information concerning methodologies, techniques and available results of research relating to such emergencies. Effective medical response is a necessary component of the overall response to nuclear or radiological (radiation) emergencies. In general, the medical response may represent a difficult challenge for the authorities due to the complexity of the situation, often requiring specialized expertise, and special organizational arrangements and materials. To be effective, adequate planning and preparedness are needed. This manual, if implemented, should help to contribute to coherent international response. The manual provides the practical tools and generic procedures for use by emergency medical personnel during an emergency situation. It also provides guidance to be used at the stage of preparedness for development of medical response capabilities. The manual also addresses mass casualty emergencies resulting from malicious acts involving radioactive material. This part was supported by the Nuclear Security Fund. The manual was developed based on a number of assumptions about national and local capabilities. Therefore, it must be reviewed and revised as part of the planning process to match the potential accidents, threats, local conditions and other unique characteristics of the facility where it may be used

    Reliability of emergency onsite ac power systems at nuclear power plants has been questioned within the Nuclear Regulatory Commission (NRC) because of the number of diesel generator failures reported by nuclear plant licensees and the reactor core damage that could result from diesel failure during an emergency. This report contains the results of a reliability analysis of the onsite ac power system, and it uses the results of a separate analysis of offsite power systems to calculate the expected frequency of station blackout. Included is a design and operating experience review. Eighteen plants representative of typical onsite ac power systems and ten generic designs were selected to be modeled by fault trees. Operating experience data were collected from the NRC files and from nuclear plant licensee responses to a questionnaire sent out for this project

    The National Disaster Management Authority (NDMA), ever since it's formation as an apex policy making body for the country in the field of disaster management, has formulated a set of guidelines to assist the various ministries, states and stakeholders in preparing their plans to handle different types of disasters. The guidelines on management of nuclear and radiological emergencies assume great importance in the present context, as our country has very ambitious programme to exploit nuclear energy for peaceful uses. Though, we have an enviable and impeccable record of safety and virtually fail-safe operations in all our nuclear establishments, the possibility, however, remote it may be, of human error, systems failure, sabotage, earthquake, floods, terrorist attacks etc leading to the release of radioactive material in the public domain, cannot be entirely ruled out. With this view, it was decided to prepare the national guidelines by NDMA to manage any nuclear/radiological emergency in public domain. Through these guidelines, we aim to further strengthen our existing nuclear/radiological emergency management framework and generate public awareness, which will go a long way in allaying misapprehensions, if any, amongst the public about the country's nuclear programme. Like in all our guidelines for handling of different types of the disasters, in these Guidelines also, maximum emphasis has been laid on the prevention of nuclear and radiological emergencies, along with a detailed consideration of all other elements of the disaster management continuum. The national guidelines have been prepared and a consensus was arrived on various issues, after widespread consultations and elaborates discussions amongst experts as well as stakeholders. It is assumed that once these guidelines are implemented by the stakeholders and converted into action plans followed by SOPs that will further reduce the chances of accidents in the nuclear arena.

    The accident at the Chernobyl nuclear power station in April 1986 and its consequences were reason for the Dutch government to evaluate and improve the facilities and the preparedness for nuclear emergency management in the Netherlands. The results of the evaluation have been elaborated in operational terms in the National Plan for Nuclear Emergency Planning and Response (EPR). During an accident with radioactive material the Technical Information Group (TIG) coordinates the measuring activities of the so-called Support Centres. According to the EPR, measuring activities of Support Centre RIVM are focussed on the collection and processing of data on emissions, concentrations, depositions and radiation doses from soil and air. This report describes the measuring strategy of RIVM for nuclear emergencies. The measuring strategy and the measuring plan, the latter deduced from the measuring strategy, concentrate on explicit answers to the following central questions: what has to be measured, by whom, where, when and how, and why? The demands of the TIG and the specification of tasks and operational facilities of Support Centre RIVM are considered as starting-points, limiting conditions and constraints for the measuring strategy. These items are converted to explicit choices for the measuring strategy and the default measuring plan. This report further includes a list of contacts of Support Centre RIVM with other (research) institutes, inside and outside the Netherlands, which may be relevant during a nuclear emergency. 3 figs., 2 tabs., 22 refs

    International Nuclear Information System (INIS)

    2000-01-01

    Since the accident at Chernobyl in 1986, many countries have intensified their efforts in nuclear emergency planning, preparedness and management. Experience from the NEA nuclear emergency exercises (INEX 1 and INEX 2) indicated a need to improve the international system of communication and information in case of a radiological emergency. To address this need, research was carried out by three NEA working groups, the findings of which are synthesised in the present report. This report defines emergency monitoring and modelling needs, and proposes strategies which will assist decision makers by improving the selection of data that is transmitted, and the way in which data and information are transmitted and received. Modern communication methods, such as the Internet, are a key part of the strategies described. (author)

    The Atomic Energy Control Board (AECB) is responsible for the regulation of the health, safety and environmental consequences of nuclear activities in Canada. Recently, the Human Factors Specialists of the AECB have become involved in the assessment of emergency preparedness and emergency response at nuclear facilities. One key contribution to existing AECB methodology is the introduction of Behaviourally Anchored Rating Scales (BARS) to measure crew interaction skills during emergency response drills. This report presents results of an on-going pilot study to determine if the BARS provide a reliable and valid means of rating the key dimensions of communications, openness, task coordination and adaptability under simulated emergency circumstances. To date, the objectivity of the BARS is supported by good inter-rater reliability while the validity of the BARS is supported by the agreement between ratings of crew interaction and qualitative and quantitative observations of crew performance.

    Full Text Available Nuclear hazards, linked to both U.S. weapons programs and civilian nuclear power, pose substantial environment justice issues. Nuclear power plant (NPP reactors produce low-level ionizing radiation, high level nuclear waste, and are subject to catastrophic contamination events. Justice concerns include plant locations and the large potentially exposed populations, as well as issues in siting, nuclear safety, and barriers to public participation. Other justice issues relate to extensive contamination in the U.S. nuclear weapons complex, and the mining and processing industries that have supported it. To approach the topic, first we discuss distributional justice issues of NPP sites in the U.S. and related procedural injustices in siting, operation, and emergency preparedness. Then we discuss justice concerns involving the U.S. nuclear weapons complex and the ways that uranium mining, processing, and weapons development have affected those living downwind, including a substantial American Indian population. Next we examine the problem of high-level nuclear waste and the risk implications of the lack of secure long-term storage. The handling and deposition of toxic nuclear wastes pose new transgenerational justice issues of unprecedented duration, in comparison to any other industry. Finally, we discuss the persistent risks of nuclear technologies and renewable energy alternatives.

    Based on current regulations, FEMA approves each site-specific plan of state and local governments for each power reactor site after 1) formal review offsite preparedness, 2) holding a public meeting at which the preparedness status has been reviewed, and 3) a satisfactory joint exercise has been conducted with both utility and local participation. Annually, each state, within any position of the 10-mile emergency planning zone, must conduct a joint exercise with the utility to demonstrate its preparedness for a nuclear accident. While it is unlikely that these extreme measures will be needed as a result of an accident at a nuclear power station, the fact that these plans have been well thought out and implemented have already proven their benefit to society. The preparedness for a nuclear accident can be of great advantage in other types of emergencies. For example, on December 11, 1982, a non-nuclear chemical storage tank exploded at a Union Carbide plant in Louisiana shortly after midnight. More than 20,000 people were evacuated from their homes. They were evacuated under the emergency response plan formulated for use in the event of a nuclear accident at the nearby Waterford Nuclear plants. Clearly, this illustrates how a plan conceived for one purpose is appropriate to handle other types of accidents that occur in a modern industrial society

    This report by the NKS/BOK-1.4 project subgroup describes transfer factors for radiocaesium and radiostrontium for the fallout year and the years after the fallout. The intention has been to collect information on tools to assess the order of magnitude of radioactive contamination of agricultural products in an emergency situation in Nordic environment. The report describes transfer paths from fallout to plant, from soil to plant and to animal products. The transfer factors of radionuclides (Sr, Cs, I) given in the report are intended to be used for making rough estimates of the contamination of agricultural products soon after the heaviness and composition of the deposition (Bq m{sup -2}) is known.

    As a result of the accident at Three Mile Island on March 28, 1979, increased emphasis has been placed on the public information capabilities of utility companies, and particularly their crisis public information procedures. A special industry task force was assigned to develop a generic model for a utility crisis public information plan. This report has been prepared not as a literal emergency plan for a utility, but as a generic check-off list of items and procedures that a utility should consider as a part of its own plan. Because of considerable variations in service areas, utility organization, and other factors, specific approaches may vary from utility to utility. The approaches cited here are generic suggestions that would help lead to an industrywide ability to inform the public, quickly and accurately, about non-routine events that it would consider of importance

    Full text: When a therapeutic dose of 131 I is indicated, especially in the thyroid carcinomas, the authorized doctor must always have present the possibility that the patient eliminates high activities of the radio-active material with the vomit. Keeping in mind that dose of 100 to 200 mCi is habitual in the carcinoma of thyroid, this episode can constitute a true radiological emergency, particularly because the first ones in taking knowledge of the fact can be people without appropriate preparation to this situation, what can cause contaminations difficult to manage them. Because it is not acceptable that a source open of high activity remains without treatment long time, the authorized doctor must act immediately, for that which should be prepared with anticipation, and have the necessary elements, to have an operative routine and to administer the storage of the polluted elements appropriately. To such an effect, we have orchestrated a sequential program of performance of 11 points, in the cases of plentiful vomits, with contamination of floors and things of the room. The program begins with the writing instructions for the patient and the personnel of infirmary in case of feeling desires to vomit, and de program is completed in case of being necessary. The elements are detailed in a handbag that contains for radiological emergencies for vomit. It notes that the low cost of the elements and clothes kind for surgery disposable. It discusses about the necessity of having prepared rooms for to receive patient with treatment with 131 I, in the clinics and public hospitals. (author) [es

    The effectiveness of measures taken in case of accident or emergency to protect the site personnel, the general public and the environment will depend heavily on the adequacy of the emergency plan prepared in advance. For this reason, an emergency plan of the operating organization shall cover all activities planned to be carried out in the event of an emergency, allow for determining the level of the emergency and corresponding level of response according to the severity of the accident condition, and be based on the accidents analysed in the SAR as well as those additionally postulated for emergency planning purposes. The purpose of this paper is to present the practice of the emergency planning and preparedness in the Dalat Nuclear Research Institute (DNRI) for responding to accidents/incidents that may occur at the DNRI. The DNRI emergency plan and emergency procedures developed by the DNRI will be discussed. The information in the DNRI emergency plan such as the emergency organization, classification and identification of emergencies; intervention measures; the co-ordination with off-site organizations; and emergency training and drills will be described in detail. The emergency procedures in the form of documents and instructions for responding to accidents/incidents such as accidents in the reactor, accidents out of the reactor but with significant radioactive contamination, and fire and explosion accidents will be mentioned briefly. As analysed in the Safety Analysis Report for the DNRI, only the in-site actions are presented in the paper and no off-site emergency measures are required. (author)

    Medical staffs and health physicists have shown deep concerning at the emergency plans of nuclear power plants after the TMI nuclear accident. The most important and basic countermeasure for accidents was preparing appropriate and concrete organization and plans for treatment. We have planed emergency medical treatment for radiation workers in a nuclear power plant institute. The emergency medical treatment at institute consisted of two stages, that is on-site emergency treatment at facility medical service. In first step of planning in each stage, we selected and treatment at facility medical service. In first step of planning in each stage, we selected and analyzed all possible accidents in the institute and discussed on practical treatments for some possible accidents. The manuals of concrete procedure of emergency treatment for some accidents were prepared following discussion and facilities and equipment for medical treatment and decontamination were provided. All workers in the institute had periodical training and drilling of on-site emergency treatment and mastered technique of first aid. Decontamination and operation rooms were provided in the facillity medical service. The main functions at the facility medical service have been carried out by industrial nurses. Industrial nurses have been in close co-operation with radiation safety officers and medical doctors in regional hospital. (author)

    Water is stored previously in an equipment storage pit disposed on an operator floor of a reactor building instead of a condensate storage vessel. Upon occurrence of an emergency, water is supplied from the equipment storage pit by way of a sucking pipeline to a pump of a high pressure reactor core water injection circuit and a pump of a reactor-isolation cooling circuit to supply water to a reactor. The equipment storage pit is arranged in a building so that the depth thereof is determined to keep the required amount of water by storing water at a level lower than the lower end of a pool gate during normal operation. Water is also supplied from the equipment storage pit by way of a supply pipeline to a spent fuel storage pool on the operation floor of the reactor building. Namely, water is supplied to the spent fuel storage pool by a pump of a fuel pool cooling and cleaning circuit. This can eliminate a suppression pool cleaning circuit. (I.N.)

    1984-01-01

    The operators of nuclear installations in the United Kingdom have plans to deal with accidents or emergencies at their nuclear sites. These plans provide for any necessary action, both on and off the nuclear site, to protect members of the public and are regularly exercised. The off-site actions involve the emergency services and other authorities which may be called upon to implement measures to protect the public in any civil emergency. In a recent review of these plans by Government Departments and agencies and the nuclear site operators, a number of possible improvements were identified. These improvements are concerned mainly with the provisions made for liaison with local and national authorities and for public information and have been incorporated into existing plans. An outline is given of the most likely consequences of an accidental release of radioactive material and the scope of emergency plans. Details are also provided on the responsibilities and functions of the operator and other organizations with duties under the plans and the arrangements made for public information. (author)

    The recently revised Royal Decree of 17 October 2003 (the Belgian Monitor of 22 November 2003) stipulating the nuclear emergency plan for radiological risks on the Belgian territory aims at reducing the impact of a radiological or nuclear accident to the population. It describes the organisation, tasks and necessary interactions between the different participating entities at the federal, provincial and communal level. It also foresees that each major nuclear installation holds regularly exercises with the different off-site entities to test and improve the response procedures. Under contract with the Ministry of Interior, and in consortium with AVN and IRE, SCK-CEN has been assigned as co-ordinator for the improvement of the methodology for emergency exercises, and to apply this for the 2005 exercises of the nuclear installations of Doel and Tihange. The main objective of this project is to define a methodology allowing to conduct exercises in a more efficient way. The methodology is based on the IAEA EPR-EXERCISE (2005) publication. This should in turn (1) allow the principal actors to train the different aspects of a nuclear crisis, (2) allow easier detection of deficiencies in the emergency plan and its application, and (3) result in the necessary corrective actions to improve future responses to crises

    The global expansion of nuclear energy will require international cooperation to ensure that nuclear materials, facilities, and sensitive technologies are not diverted to non-peaceful uses. Developing countries will require assistance to ensure the effective regulation, management, and operation of their nuclear programs to achieve best practices in nuclear nonproliferation. A developing nation has many hurdles to pass before it can give assurances to the international community that it is capable of implementing a sustainable nuclear energy program. In August of this year, the U.S. Department of Energy and the Ministry of Science and Technology of the Socialist Republic of Vietnam signed an arrangement for Information Exchange and Cooperation on the Peaceful Uses of Nuclear Energy. This event signals an era of cooperation between the U.S. and Vietnam in the area of nuclear nonproliferation. This paper will address how DOE is supporting the development of secure and sustainable infrastructures in emerging nuclear nations such as Vietnam

    Care system; Radiological Emergency Supporting System. Environmental radiology level is the main aspect that should be concerned deal with the utilization of nuclear energy. The usage of informational technology in nuclear area gives significant contribution to anticipate and to protect human and environment. Since 1960, South Korea has developed environment monitoring system as the effort to protect the human and environment in the radiological emergency condition. Indonesia has possessed several nuclear installations and planned to build and operate nuclear power plants (PLTN) in the future. Therefore, Indonesia has to prepare the integrated system, technically enables to overcome the radiological emergency. Learning from the practice in South Korea, the system on the radiological emergency should be prepared and applied in Indonesia. However, the government regulation draft on National Radiological Emergency System, under construction, only touches the management aspect, not the technical matters. Consequently, when the regulation is implemented, it will need an additional regulation on technical aspect including the consideration on the system (TSS), the organization of operator and the preparation of human resources development of involved institution. For that purpose, BAPETEN should have a typical independence system in regulatory frame work. (author)

    Management of Nuclear and Radiological Emergencies arising from Radiological Dispersive Device (RDD), Improvised Nuclear Devices (IND), Nuclear Reactors/Power plants and Nuclear War require measurement of ionizing radiations and radioactivity on an enhanced scale relative to the levels encountered in peaceful uses of ionizing radiations and radioactivity. It is heartening that since Hiroshima, Nagasaki nuclear disaster, the world has been quiet but since early 2000 there has been a fear of certain devices to be used by terrorists, which could lead to panic, and disaster due to dispersal of radioactivity by RDD, IND. Nuclear attack would lead to blast, thermal, initial nuclear radiation, nuclear fall out leading to gamma and neutron dose, dose rates in range from few R, R/h to kR, kR/h, and determinations of k Bq or higher order. Such situations have been visualized at national levels and National Disaster Management Authority NDMA has been established and Disaster Management Act 2005 has come into existence. NDMA has prepared guidelines for Nuclear and radiological emergency management highlighting preparedness, mitigation, response, capacity building, etc. Critical point in all these issues is detection of emergency, quick intimation to the concerned for action in shortest possible time. Upper most requirement by those involved in pursuing action, is radiation sensor based radiation monitors for personnel, area, and to assess contamination due to radioactivity.This presentation briefly describes the Indian scenario in the development of the radiation sensors and the sensor-based radiation monitors.

Nuclear attack would lead to blast, thermal, initial nuclear radiation, nuclear fall out leading to gamma and neutron dose, dose rates in range from few R, R/h to kR, kR/h, and determinations of k Bq or higher order. Such situations have been visualized at national levels and National Disaster Management Authority NDMA has been established and Disaster Management Act 2005 has come into existence. NDMA has prepared guidelines for Nuclear and radiological emergency management highlighting preparedness, mitigation, response, capacity building, etc. Critical point in all these issues is detection of emergency, quick intimation to the concerned for action in shortest possible time. Upper most requirement by those involved in pursuing action, is radiation sensor based radiation monitors for personnel, area, and to assess contamination due to radioactivity.This presentation briefly describes the Indian scenario in the development of the radiation sensors and the sensor-based radiation monitors.

  7. Nuclear accident/radiological emergency assistance plan. NAREAP - edition 2000. Emergency preparedness and response

    International Nuclear Information System (INIS)

    2000-01-01

    The purpose of the Nuclear Accident/Radiological Emergency Assistance Plan (NAREAP) is to describe the framework for systematic, integrated, co-ordinated, and effective preparedness and response for a nuclear accident or radiological emergency involving facilities or practices that may give rise to a threat to health, the environment or property. The purpose of the NAREAP is: to define the emergency response objectives of the Agency's staff in a nuclear accident or a radiological emergency; to assign responsibilities for performing the tasks and authorities for making the decisions that comprise the Agency staff's response to a nuclear accident or radiological emergency; to guide the Agency managers who must ensure that all necessary tasks are given the necessary support in discharging the Agency staff responsibilities and fulfilling its obligations in response to an emergency; to ensure that the development and maintenance of detailed and coherent response procedures are well founded; to act as a point of reference for individual Agency staff members on their responsibilities (as an individual or a team member) throughout a response; to identify interrelationships with other international intergovernmental Organizations; and to serve as a training aid to maintain readiness of personnel. The NAREAP refers to the arrangements of the International Atomic Energy Agency and of the United Nations Security and Safety Section at the Vienna International Centre (UNSSS-VIC) that may be necessary for the IAEA to respond to a nuclear accident or radiological emergency, as defined in the Early Notification and Assistance Conventions. It covers response arrangements for any situation that may have actual, potential or perceived radiological consequences and that could require a response from the IAEA, as well as the arrangements for developing, maintaining and exercising preparedness. The implementing procedures themselves are not included in the NAREAP, but they are required

    On March 11, 2011, the Fukushima Dai-ichi Nuclear Power Station of the Tokyo Electric Power Company ('TEPCO') was hit and damaged by a magnitude 9 earthquake and accompanying tsunami. The accident is determined to be of the highest rating on the International Nuclear Event Scale. The Government of Japan and TEPCO have taken emergency response actions on-site and off-site at the accident. It became clear through the investigation that the accident had been initiated on the occasion of a natural disaster of an earthquake and tsunami, but there have been various complex problems behind this very serious and large scale accident. For an example, the then-available accident preventive measures and disaster preparedness of TEPCO were insufficient against tsunami and severe accidents; inadequate TEPCO emergency responses to the accident at the site were also identified. The accident rang the alarm for the nuclear safety of nuclear power plants. It also taught us a great of lessons in nuclear emergency management. (authors)

    2009-01-01

    An effective and sustainable national safety and secure regime is a goal and a challenge to countries considering the benefits of power and non-power applications of nuclear energy. This will provide for protection of people and environment from the effects of ionizing radiation. Moreover, this will minimize the possibility of accidents and the occurrence of malicious acts. Such a regime involves the establishment of institutional, legal and technical frameworks to support and sustain the implementation of nuclear applications in a coordinated manner. This paper describes the key constraints and challenges that emerging nuclear countries face in the process of developing such frameworks when preparing themselves to implement the envisaged nuclear activities. The role of the government, the issues involved, the difficulties common to developing countries, the assistance available and the way forward are discussed.(Author)

    The accidents at TMI-2 and Chernobyl have produced initiatives aimed at improving nuclear plant emergency response capabilities. Among them are the development of emergency response facilities with capabilities for the acquisition, processing, and diagnosis of data which are needed to help coordinate plant operations, engineering support and management under emergency conditions. An effort in this direction prompted the development of an expert system. EP (EMERGENCY PLANNER) is a prototype expert system that is intended to help coordinate the overall management during emergency conditions. The EP system was built using the GEN-X expert system shell. GEN-X has a variety of knowledge representation mechanisms including AND/OR trees, Decision trees, and IF/THEN tables, and runs on an IBM PC-XT or AT computer or compatible. Among the main features, EP is portable, modular, user friendly, can interact with external programs and interrogate data bases. The knowledge base is made of New York State (NYS) Procedures for Emergency Classification, NYS Radiological Emergency Preparedness Plan (REPP) and knowledge from experts of the NYS Radiological Emergency Preparedness Group and the Office of Radiological Health and Chemistry of the New York Power Authority (NYPA)

    Emergency situations demand that actions be taken by responsible organisations in a timely and effective manner to mitigate consequences for the population, infrastructure and the environment, and to support the return of affected areas to normal social and economic activity to the extent possible. To deliver an effective response over the emergency management time-line, it is necessary to make, maintain and exercise adequate plans and arrangements in advance of an emergency situation. These must contain appropriate elements and resources for preparedness, response and assistance to identified threats, recognize and include all implicated partners, and take account of international interfaces. Effective management of complex emergency situations that can lead to a wide range of consequences and involve multiple organisations at the local, national and international levels also requires anticipation of the range of decision-making needs, an understanding of the interactions between response organisations and a model for their co-ordination. Experience from managing emergency situations has shown that the integration of these factors into emergency preparedness and response arrangements should be based on a guiding strategic vision. Emergency response is a dynamic process that develops in time from a situation of little information to one of potentially overwhelming information. Within this context, emergency response organisations must be able to respond in an appropriate and timely manner at any point along the emergency management time-line. This will be facilitated by an overarching framework to guide the decision-making process. To contribute to work in this area, the NEA Committee on Radiation Protection and Public Health (CRPPH) Working Party on Nuclear Emergency Matters (WPNEM) reviewed its collective experience to extract key themes that could form a strategy for improving decision-making in emergency management. This focused on the NEA International Nuclear

  14. Generic procedures for monitoring in a nuclear or radiological emergency

    International Nuclear Information System (INIS)

    1999-06-01

    One of the most important aspects of managing a radiological emergency is the ability to promptly and adequately assess the need for protective actions. Protective action accident management must make use of the key relevant information available. Decision-making and accident assessment will be an iterative and dynamic process aimed at refining the initial evaluation as more detailed and complete information becomes available. Emergency monitoring is one of the main sources for obtaining needed information. This publication is in the scope of the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Legal Series No. 14) under which the IAEA is authorized to assist a State Party or a Member State among other matters in developing appropriate radiation monitoring programmes, procedures and standards (Article 5). The scope of this manual is restricted to practical guidance for environmental and source monitoring during a nuclear or other radiological emergency. It does not address emergency response preparedness, nor does it cover the emergency management aspects of accident assessment. This manual is organised into sections relating to measurements in order of priority of a major reactor accident, namely: ambient gamma/beta dose rates from plume, ground deposition or source; radionuclide concentrations in air; deposition maps for 131 I and 137 Cs and other important radionuclides; radionuclide mix in deposition and radionuclide concentrations in food, drinking water and other samples. The introductory section provides an overview of the design of emergency monitoring and sampling programmes, monitoring teams and their qualifications and training, monitoring equipment and instrumentation, protective actions for emergency monitoring teams and quality assurance and quality control checks

    Nuclear power plants are designed and built with systems dedicated to provide a high degree of protection to its workers, the population living in their neighborhoods and the environment. Among the requirements for ensuring safety there are the existence of the nuclear emergency plan. Due to the relationship between the actions contemplated in the emergency plan and the nuclear emergency exercise, it becomes possible to assess the quality of the nuclear emergency plan, by means of emergency exercise evaluation, The techniques used in this work aim at improving the evaluation method of a nuclear emergency exercise through the use of performance indicators in the evaluation of the structures, actions and procedures involved. The proposed model enables comparisons between different moments of an emergency plan directed to a nuclear power plant as well as comparisons between plans dedicated to different facilities.

    1987-01-01

    The safety of present and future nuclear power plants is considered, with particular reference to the human components of these plants. The approach by the United Kingdom Nuclear Installations Inspectorate is particularly criticised. In particular, objections are made to the use of event and fault tree analyses. The UK NII have also decided that comprehensive quantification of human reliability is not feasible. However, figures presented show that the human contribution to monitored power plant emergencies is high, by far the greatest proportion of root causes of emergencies were attributable to human performance. The origins of, and problems with, 'principle 124' are discussed. Automatic safety systems are also distrusted. Current probabilistic risk assessment and probabilistic safety analysis is seen as an unsatisfactory basis for the setting of safety targets. (UK)

    The 'Nuclear Regulatory Authority (NRA) (ARN in Spanish)' and the 'National Meteorological Office (NMO) (SMN in Spanish)' of Argentine has been working together on the improvement of both meteorological forecasting and dispersion prediction. In the pre-release phase of a nuclear emergency, it is very important to know the wind direction and the forecast of it, to establish the area, around the installation, where the emergency state is declared and to foresee the modification of this area. Information is also needed about deterministic effects, to begin the evacuation. At this time, meteorological forecast of wind direction and speed, and the real time meteorological information is available in the nuclear power plant (NPP) and in the Nuclear Emergency Control Centre at the ARN headquarters, together with the short-range dose calculation provided by our dispersion code, SEDA. By means of the SEDA code, we can estimate the optimum place to measure the radioactive material concentration in air, needed do to reduce evaluation uncertainties due, among others, to poor knowledge of the source term. The SEDA code allows considering atmospheric condition, and the need to reduced doses of the measuring team in charge of the measurements. For the evaluation in the medium range, we participate in the project IXP, which provides four hours and about 50 kilometres forecast. In the long-range movement of air borne radioactivity, the World Meteorological Organization (WMO), whose contact point in Argentina is the SMN, can assist us. We have developed together, with the SMN, a detailed procedure to request assistance from the WMO. In this work, we describe the combined tasks that were carried out with the SMN to define the procedures and the concepts for their application during a real emergency. The results of an application exercise carried out in 2006 are also described. (author)

    Waller, Edward; Bereznai, George; Shaw, John; Chaput, Joseph; Lafortune, Jean-Francois

    Training offsite emergency response personnel basic awareness of onsite control room operations during nuclear power plant emergency conditions was the primary objective of a week-long workshop conducted on a CANDU® virtual nuclear reactor simulator available at the University of Ontario Institute of Technology, Oshawa, Canada. The workshop was designed to examine both normal and abnormal reactor operating conditions, and to observe the conditions in the control room that may have impact on the subsequent offsite emergency response. The workshop was attended by participants from a number of countries encompassing diverse job functions related to nuclear emergency response. Objectives of the workshop were to provide opportunities for participants to act in the roles of control room personnel under different reactor operating scenarios, providing a unique experience for participants to interact with the simulator in real-time, and providing increased awareness of control room operations during accident conditions. The ability to "pause" the simulator during exercises allowed the instructors to evaluate and critique the performance of participants, and to provide context with respect to potential offsite emergency actions. Feedback from the participants highlighted (i) advantages of observing and participating "hands-on" with operational exercises, (ii) their general unfamiliarity with control room operational procedures and arrangements prior to the workshop, (iii) awareness of the vast quantity of detailed control room procedures for both normal and transient conditions, and (iv) appreciation of the increased workload for the operators in the control room during a transient from normal operations. Based upon participant feedback, it was determined that the objectives of the training had been met, and that future workshops should be conducted.

    In various phases of a disaster, the result of decision-making should finally reach the local public of interest, and the detriment among the public should be minimized optimized according to the proper response by the public who receive the result. The decision involves the proper selection among countermeasures, and should reach each one of the public. The expression to be informed to the public should be quite understandable in its meaning. After Hanshin big earthquake (Jan. 17, 1995), the basic plan for countermeasures against disasters which is the foundation for the basic law for disasters has been largely revised and reissued in July 1995. For preparedness and countermeasures outside a nuclear facility, there are many useful experiences that have to be learnt from natural disasters. In Japan and China, there have been no major nuclear accidents affecting the public in the environment. However, preparedness for nuclear emergency derived from natural disasters is important.

    Emergency conditions after a nuclear accident are different in each case and cannot be predicted accurately. The accident at TMI did not contaminate the environment. The accident at Chernobyl had a large, early release of nuclear contamination, widely dispersed over many countries. Although there was no large, early release of contamination at Fukushima Daiichi, the timeline of the accident included days of later contamination of various degrees of severity. A large amount of the contamination has been released to the ocean and an exclusion zone still exists around the station. In all of these accidents there were no adequate radiation monitoring systems distant from the origin point that could provide accurate status to the authorities and the local population. In the recent years a number of new nuclear monitoring systems have been implemented or are under development to be installed in areas that might be exposed to nuclear contamination in emergencies. Based on the risk informed optimization methodology, this paper provides recommendations for selecting the quantity and type of instrumentation, the location and sampling of data, and the real-time processing of information.

    This report first presents nuclear emergency plans in France (specific intervention plans, action at the municipal level, creation of a national plan, planning of the post-accidental phase, integration of the international and cross-border dimension. Then, it analyses strengths and weaknesses of these plans. It outlines the necessity to take the most severe accident scenarios into account (issue of selection of reference accidents, necessity of reviewing emergency planning areas, and assessment of the number of inhabitants about French nuclear installations). It proposes a review of measures of protection of populations (information, sheltering, iodine-based prophylaxis, evacuation, food control and restrictions, protection of human resources, cross-border problems). It discusses how to put an end to the emergency situation, and the assessment and collaboration on emergency plans. The next part proposes an analysis of noticed strengths and weaknesses in some PPIs (specific intervention plans) in terms of text accessibility, of description of the site and of its environment, of intervention area, of operational measures, and of preparation to the post-accidental phase

    In the case of an operating reactor, if it is determined that there are such deficiencies that a favourable NRC finding is not warranted and if the deficiencies are not corrected within four months of that determination, the Commission will determine whether the reactor should be shut down or whether some other enforcement action is appropriate. In any case, where the Commission believes that the public health, safety, or interest so requires, the plant will be required to shut down immediately. Emergency planning considerations must be extended to emergency planning zones, and these shall consist of an area of about 10 miles in radius for exposure to the radioactive plume that might result from an accident in a nuclear power reactor and an area of about 50 miles in radius for food that might become contaminated. To evaluate the effectiveness of the licensee programme to implement their emergency plan, a 'management oversight and risk tree' (MORT) approach was developed and used by NRC appraisal teams at all operating facilities and those close to licensing. Since April 1981, over 250 emergency preparedness exercises have been observed and annual inspections conducted at US commercial nuclear power generating facilities. As a result of this experience, licensees have generally progressed from a basic ability to implement their plan to a systematic demonstration of their emergency preparedness capabilities. Almost five years have elapsed since the inception of the upgraded emergency preparedness regulatory programme, and the NRC is evaluating the resources committed to the programme to determine if modifications are appropriate. Our goal is to ensure continued adequate readiness capability to protect the public health and safety in the event of an accident

    The nuclear industry has extensive radiological emergency planning (REP) experience that is directly applicable to hazardous materials emergency planning. Recently, the Feed Materials Production Center near Cincinnati, Ohio, successfully demonstrated such application. The REP experience includes conceptual bases and standards for developing plans that have been tested in hundreds of full-scale exercises. The exercise program itself is also well developed. Systematic consideration of the differences between chemical and radiological hazards shows that relatively minor changes to the REP bases and standards are necessary. Conduct of full-scale, REP-type exercises serves to test the plans, provide training, and engender confidence and credibility

    Full text: A large number of different national plans and procedures have been established and substantial resources allocated world wide with varying comprehensiveness and quality depending an the national requirements and the possible threat scenarios considered. These national plans are only to a small degree harmonized. It is clear that it is the responsibility of the authorities in the respective countries or utilities under their jurisdiction, to decide upon and implement appropriate response actions to a nuclear emergency. The basic needs for responding properly are: infrastructure in terms of plans, procedures etc.; information regarding the accident, its development and consequences; resources in terms of expertise, man power and tools for acquiring and processing information, making assessments and decisions and carry out the actions. When a large number of countries are making assessments and decisions for their own country and providing the public with information, it is important that assessments, decisions and public information become correct, complete and consistent across boarders. In order to achieve this, they should all have access to the same information as basis for their actions. Lack of information or wrong information could easily lead to wrong assessments, wrong decisions and misleading information to the public. If there is a serious nuclear emergency somewhere that could potentially affect several or many States in one way or another, 'everyone' would like to know 'everything' that happens 'everywhere'. In this case, all States should have the obligation to share with the international community the relevant information they have available themselves and that could be of interest for other States responding to the situation. During a serious nuclear or radiological emergency, the demand for different kinds of resources is huge and could, in many countries, probably exceed national capabilities. Looking at the situation in a global

    2005-09-01

    Japan Atomic Energy Research Institute (JAERI) have conducted the analytical studies on the Probabilistic Safety Assessment (PSA), the severe accidents, and the optimization of protective actions. Based on the results of these studies, JAERI are investigating the method for taking urgent protective actions more reasonably. If an accident occurs in a nuclear power plant (NPP), early protective actions are carried out. To implement these actions more effectively, emergency preparedness and emergency planning are important, and especially prompt evacuation is expected to reduce a large amount of radiation exposures. To examine the effect of early protective measures by using a PSA method, estimation of the parameter uncertainty related in the time for early protective actions is needed. For this purpose, we have developed an analytical method for urgent protective actions using geographic information, and estimated the movement distance based on gathering points arrangement an population distribution. For this analysis, we used the gathering point data shown on each regional plans for disaster prevention which will be used in actual emergency situation and targeted the population inside Emergency Planning Zone (EPZ). By applying this method for the existing sixteen commercial NPP sites, we estimated the average value and distribution of the movement distance for each sites. This report provides a brief description of the method for estimating the movement distance, input data for this analysis, and the result. Moreover, the problem on the method of evacuation distance analysis and usefulness of this method for emergency planning were discussed. (author)

  11. Elements of a national emergency response system for nuclear accidents

    International Nuclear Information System (INIS)

    Dickerson, M.H.

    1987-01-01

    The purpose of this paper is to suggest elements for a general emergency response system, employed at a national level, to detect, evaluate and assess the consequences of a radiological atmospheric release occurring within or outside of national boundaries. These elements are focused on the total aspect of emergency response ranging from providing an initial alarm to a total assessment of the environmental and health effects. Elements of the emergency response system are described in such a way that existing resources can be directly applied if appropriate; if not, newly developed or an expansion of existing resources can be employed. The major thrust of this paper is toward a philosophical discussion and general description of resources that would be required to implementation. If the major features of this proposal system are judged desirable for implementation, then the next level of detail can be added. The philosophy underlying this paper is preparedness - preparedness through planning, awareness and the application of technology. More specifically, it is establishment of reasonable guidelines including the definition of reference and protective action levels for public exposure to accidents involving nuclear material; education of the public, government officials and the news media; and the application of models and measurements coupled to computer systems to address a series of questions related to emergency planning, response and assessment. It is the role of a proven national emergency response system to provide reliable, quality-controlled information to decision makers for the management of environmental crises

    2014-01-01

    The INEX series of international nuclear emergency exercises, organised under the auspices of the NEA Working Party on Nuclear Emergency Matters (WPNEM), has proven successful in testing, investigating and improving national and international response arrangements for nuclear accidents and radiological emergencies. The Fukushima Daiichi nuclear power plant (NPP) accident occurred during INEX-4 and had a direct impact on NEA technical standing committees' work programmes. The WPNEM played an important role during the emergency, following and studying the insights and ideas that drive nuclear emergency management decision making. It collected crucial information on governmental decisions and recommendations with respect to the accident situation, and implemented a framework study to assist in the collection of NEA member country experiences that would facilitate the identification of commonalities in national assessment approaches and results. The findings triggered the INEX-5 exercise, which will build upon the experiences and lessons learnt from past nuclear accidents/incidents, and the success of previous INEX exercises. This exercise is intended to test mechanisms for decision making at the national level, particularly in uncertain circumstances or in the absence of data, to examine arrangements for international co-operation and coordination of data and information exchange among countries and arrangements for practical support and assistance between groups of countries or geographical regions. It will also investigate the long-term issues beyond the early response phase. The WPNEM agreed on a tightly focused scope, which will consist of a tabletop exercise or moderated workshop that is not based on a real time test. The exercise will be a common scenario based on a re-enactment of a nuclear power plant accident, although not the Fukushima accident. It will consider coincident impacts on multiple units and include impacts on other critical national

    Nuclear safety is the lifeline of nuclear energy and nuclear technology, nuclear accident emergency response is the last line of nuclear security defense, and is one of the important measures to ensure the healthy development of the nuclear energy safety. The establishment of complete function, sensitive reaction and efficient emergency management system for operation of nuclear and radiation accidents is an important task of nuclear security. From 2001 China Techenergy Co., Ltd. participated in the Qinshan, Tianwan, Ministry of Environmental Protection, Haiyang, Taishan, Fangchenggang, Sanmen, etc. nuclear emergency projects, and the nuclear emergency EmInfoSys (emergency management information system) platform was developed with independent intellectual property rights. A brief introduction about EmInfoSys system was performed in this paper. (authors)

  14. Safety assessment of emergency power systems for nuclear power plants

    International Nuclear Information System (INIS)

    1992-01-01

    This publication is intended to assist the safety assessor within a regulatory body, or one working as a consultant, in assessing the safety of a given design of the emergency power systems (EPS) for a nuclear power plant. The present publication refers closely to the NUSS Safety Guide 50-SG-D7 (Rev. 1), Emergency Power Systems at Nuclear Power Plants. It covers therefore exactly the same technical subject as that Safety Guide. In view of its objective, however, it attempts to help in the evaluation of possible technical solutions which are intended to fulfill the safety requirements. Section 2 clarifies the scope further by giving an outline of the assessment steps in the licensing process. After a general outline of the assessment process in relation to the licensing of a nuclear power plant, the publication is divided into two parts. First, all safety issues are presented in the form of questions that have to be answered in order for the assessor to be confident of a safe design. The second part presents the same topics in tabulated form, listing the required documentation which the assessor has to consult and those international and national technical standards pertinent to the topics. An extensive reference list provides information on standards. 1 tab

  15. Basic principles for intervention after a nuclear or radiological emergency

    1996-01-01

    The current status of internationally agreed principles for intervention after a nuclear accident or radiological emergency and the international development of intervention guidance since the Chernobyl accident are reviewed. The experience gained after the Chernobyl accident indicates that the international advice on intervention existing at the time of the Chernobyl accident was not fully understood by decision makers neither in Western Europe nor in the former USSR and that the guidance failed to address adequately the difficult social problems which can arise after a serious nuclear accident. The radiation protection philosophy of today distinguishes between practices and interventions. The radiological protection system of intervention includes justification of the protective action and optimization of the level of protection achieved by that action. Dose limits do not apply in intervention situations. The inputs to justification and optimization studies include factors that are related to radiological protection, whereas the final decisions on introduction of countermeasures would also depend on other factors. The basic principles for intervention as recommended by international organisations are discussed in detail and the application of the principles on a generic basis is illustrated for long-term protective actions. The concepts of intervention level, operational intervention level and action level are presented and the relation between these quantities is illustrated. The numerical guidance on intervention in a nuclear accident or radiological emergency or a chronic exposure situation given by ICRP, IAEA and in the Basic Safety Standards is presented. (author)

  16. Initial operations in local nuclear emergency response headquarter

    2012-06-01

    As a result of the Fukushima nuclear accident due to the Great East Japan Earthquake and the tsunami that occurred thereafter, local nuclear emergency response headquarters (local headquarters) was set up at off-site center (OFC). However, several obstacles such as the collapse of means of communication resulting from severed communication lines, food and fuel shortage resulting from stagnant physical distribution, and increasing radiation dose around the center significantly restricted originally intended operation of local headquarters. In such severe situation, the personnel gathered at the OFC from the government, local public bodies and electric companies from March 11 to 15 acted without sufficient food, sleep or rest and did all they could against successively occurring unexpected challenges by using limited means of communication. However, issues requiring further consideration were activities of each functional group, location of OFC and the functions of equipment, machines and materials and reflecting the consideration results into future protective measures and revision of the manual for nuclear emergency response were greatly important. This report described investigated results on initial operations in local headquarters such as situation of activities conducted by local headquarters and operations at functional groups. (T.

    CSA Group has published a new standard on General requirements for nuclear emergency management programs (CSA N1600-14). The standard establishes criteria for the emergency management programs of on- and off-site organizations to address nuclear emergencies at Canadian nuclear power plants (NPPs). It provides the requirements to develop, implement, evaluate, maintain, and continuously improve a nuclear emergency management program for prevention and mitigation, preparedness, response, and recovery from a nuclear emergency at a NPP. This paper discusses the development of the standard, and provides the key drivers, structure, scope, and outline of the standard, while highlighting key features, impacts, and benefits. (author)

    The nuclear reactors safety is determined according to their protection against the consequences that may result from postulated accidents. The Loss of Coolant Accident (LOCA) is one the most important design basis accidents (DBA). The failure may be due to rupture of the primary loop piping. Another accident postulated is due to lack of power in the pump motors in the primary circuit. In both cases the reactor shut down automatically due to the decrease of reactivity to maintain the fissions, and to the drop of control rods. In the event of an accident it is necessary to maintain the coolant flow to remove the fuel elements residual heat, which remains after shut down. This heat is a significant amount of the maximum thermal power generated in normal operation (about 7%). Recently this event has been quite prominent in the press due to the reactor accident in Fukushima nuclear power station. This paper presents the experimental facility under rebuilding at the Thermal Hydraulic Laboratory of the Nuclear Technology Development Center (CDTN) that has the objective of monitoring and visualization of the process of emergency cooling of a nuclear fuel rod simulator, heated by Joule effect. The system will help the comprehension of the heat transfer process during reflooding after a loss of coolant accident in the fuel of light water reactor core. (author)

    We describe the results of process mapping of nuclear emergency management procedures in four European countries. We find clear differences and explore these in relation to their suitability for building a shared understanding across the emergency management team of the evolving situation and a balanced appreciation of the uncertainties. Our findings indicate that there are some issues that cause concern in that the procedures may run smoothly and efficiently but they may also risk underestimating uncertainty or ignore key issues that have only been identified by a minority of experts or models. We are concerned that they do not facilitate the building of shared mental models that the literature such as that on highly reliable organisations has shown is important.

    The Government of the Federal Republic of Germany has set emergency reference levels of radiation doses at which countermeasures such as sheltering, evacuation, iodine prophylaxis and resettlement should be considered in case of severe accidents in nuclear installations. Emergency facilities are to be set up for a range of meausres to protect the public, such as assessment of contamination and subsequent decontamination. Recommendations as to further therapeutic measures will be made by medical personnel. The administration of stable iodine can block or reduce the accumulation of radioiodine in the thyroid gland. Stable potassium iodine tablets (100 mg each) will be distributed by the local authorities. Since iodine deficiency is still prevalent in large parts of the Federal Republic of Germany, iodine prophylaxis will be recommended only when relatively high radiation doses to the thyroid gland are to be expected. Resettlement of the population must be considered if an excessive dose is expected in the affected area over a long period. (orig.) [de

    The study of environmental radioactivity is a topic not usually included in physics courses in Brazilian and Latin American universities. Consequently, high-school teachers rarely have the opportunity to discuss with their students the effects of radioactive contamination in forest and agricultural ecosystems following a nuclear or radiological emergency, or to conduct experiments to illustrate the methodology employed to assess the consequences of such an event. This paper presents a laboratory experiment which could be included as part of a teaching programme on ionizing radiation physics, addressing some of the aspects related to the fate and effects of anthropogenic radionuclides following a radiation emergency, and the possible physical countermeasures that could be adopted in order to reduce their impact on the environment.

    This book is a Japanese version of the International Atomic Energy Agency (IAEA) publication (Report No., IAEA-TECDOC-1092, published in Vienna, 1999) of the same title. The translation of the original English into Japanese was done by the Department of Dose Assessment, Research Center for Radiation Emergency Medicine, National Institute of Radiological Sciences (NIRS). Since the Department was organized in addition to the Emergency Medicine Dept. in the Center in 2003 to establish a system for rapid and accurate dose assessment at emergent radiation exposure, the translation is thus a result of the department works, and is published with permission by IAEA as one of a series of NIRS Report (NIRS-M--179) for use in the country. The book is essentially a manual for providing technical requirements and procedures for radiation monitoring, environmental sampling and laboratory analyses for a nuclear or other radiological emergency. The contents are: Introduction, Outline of monitoring, Monitoring of outdoor radiation and contamination, Outdoor sampling, Gross alpha/beta measurement, Gamma spectrometry, Activation analyses, Basic data assessment, Work-sheets, Check-list for measuring equipments, Appendices, References, and others.

  13. Optimization of emergency response to major nuclear accidents

    Papazoglou, I.A.; Christou, M.D.

    1991-01-01

    A methodology for the optimization of the short-term emergency response in the event of a nuclear accident has been developed. The method aims at an optimum combination of protective actions in the presence of a multitude of conflicting objectives and under uncertainty. Conflicting objectives arise when the minimization of the potential adverse effects of an accident and the simultaneous minimization of the associated socioeconomic impacts is attempted. Additional conflicting objectives appear whenever an emergency plan tends to decrease a particular health effect (e.g. acute deaths) while at the same time it increases another (e.g. latent deaths). The uncertainty is due to the multitude of the possible accident scenarios and their respective probability of occurrence, the stochastic variability in the weather conditions and in the variability and/or lack of knowledge in the parameters of the risk assessment models. A multiobjective optimization approach is adopted in a dynamic programming scheme. An emergency protective plan consists of defining a protective action (e.g. evacuation, sheltering) at each spatial cell around the plant. Three criteria (evaluators) are used as the objective functions of the problem, namely, acute fatalities, latent effects and socioeconomic cost. The optimization procedure defines the efficient frontier, i.e. all emergency plans that are not dominated by another in all three criteria. No value trade-offs are necessary up to this point

    This document is provided for interim use during the initial phases of the NRC effort to promptly improve emergency preparedness at operating nuclear power plants. Changes to the document can be expected as experience is gained in its use and public comments are received. Further, the Commission has initiated a rulemaking procedure, now scheduled for completion in January 1930 in the area of Emergency Planning and Preparedness. Additional requirements are to be expected when rulemaking is completed and some modifications to this document may be necessary. Four classes of Emergency Action Levels are established which replace the classes in Regulatory Guide 1.101, each with associated examples of initiating conditions. The classes are: - Notification of Unusual Event; - Alert; - Site Emergency; - General Emergency. The rationale for the notification and alert classes is to provide early and prompt notification of minor events which could lead to more serious consequences given operator error or equipment failure or which might be indicative of more serious conditions which are not yet fully realized. A gradation is provided to assure fuller response preparations for more serious indicators. The site emergency class reflects conditions where some significant releases are likely or are occurring but where a core melt situation is not indicated based on current information. In this situation full mobilization of emergency personnel in tie :near site environs is indicated as well as dispatch of monitoring teams and associated communications. The general emergency class involves actual or imminent substantial core degradation or malting with the potential for loss of containment. The immediate action for this class is sheltering (staying inside) rather thai evacuation until an assessment can be made that (1) an evacuation is indicated and (2) an evacuation, if indicated, can be completed prior to significant release and transport of radioactive material to the affected

    2003-01-01

    Full text: Radiation measurements provide indispensable data needed for the management of a nuclear or radiological emergency. There must exist pre-prepared emergency monitoring strategies, with accompanying procedures and methods, that help the authorities to perform measurements efficiently and, consequently, to evaluate the radiological situation correctly and to carry out proper countermeasures on time. However, defining a realistic yet comprehensive radiation monitoring strategy for emergencies is far from being an easy task. The very concept of 'emergency monitoring strategy' should be understood in a broad sense. In an ideal case, a strategy has interfaces with all related emergency and information exchange arrangements and agreements both at the national and international level. It covers all activities from the recognition of a potential hazard situation to environmental sampling performed during the late phases of an accident. It integrates routine-monitoring practices with the special requirements set by emergency monitoring and the use of fixed monitoring stations with that of mobile measurement teams. It includes elements for gathering, analyzing, transmitting and presenting data, as well as for combining them with different kinds of forecasts. It also takes into account the various intrinsic characteristics of possible threat scenarios and contains options for adapting measuring activities according to prevailing environmental conditions. Furthermore, a strategy must have relevant links to the social and economical realities and to the primary interests of different stakeholders. In order to assist individual countries in establishing national strategies, international organisations (IAEA, OECD/NEA, EU) have published basic guidelines for emergency response and radiation measurements. Nuclear accidents, especially the Chernobyl case with its large-scale environmental consequences, and other kinds of shocking events (like the one on September 11, 2001

  17. Strategy for developing and conducting nuclear emergency exercises

    International Nuclear Information System (INIS)

    2007-01-01

    Emergency situations demand that actions be taken by responsible organisations and individuals at the site of the emergency and at the local, national and international levels to mitigate the impact on people and the environment. Effective emergency response requires development and implementation of emergency plans and procedures; established arrangements at the local, national and international levels; acquisition and maintenance of resources (funding, equipment and personnel); training of personnel; conduct of exercises; and a 'feedback programme' whereby improvements to the emergency management system are made based on lessons identified from exercises and actual events. A means for demonstrating the effectiveness of an emergency programme is through the conduct of exercises. Exercises demonstrate the effectiveness of plans, procedures, training and equipment; adequacy of response arrangements and resources; capabilities of response personnel in performing their assigned tasks; ability of individuals and organisations to work together; and provide a forum for exploring and testing revisions, modifications, and new and/or proposed changes to any emergency programme element in near realistic situations. Exercises may range in scope from small-scale drills to large-scale national or international exercises. There is clear benefit to organisations in supporting, developing and conducting well-managed exercises. Exercising is a resource-intensive tool; however, it is a critical tool for enhancing performance, testing arrangements and identifying areas for improvement. A thoroughly developed strategy should therefore be in place to ensure maximum value from an exercise programme. This report contributes to the good practice and management of exercise programmes by providing a strategy for improving the value of planning, conducting, participating in and/or supporting exercises.

    2003-01-01

    Full text: Emergency preparedness to nuclear accidents (radiation emergency preparedness) is a part of general emergency preparedness and crisis management in the Czech Republic. The bases for it were given in 1997 when radiation emergency preparedness was defined and requirements to it were given in Act No. 18/1997 Coll., so called the Atomic Act, which entered into force in July 1997. In 2000, the bases for general emergency preparedness and crisis management in the Czech Republic were given namely in two acts - in Act No. 239/2000 Coll., an integrated rescue system, and in Act No. 240/2000 Coll., on crisis management. Both these acts entered into force on 1 January 2001. The Atomic Act determines duties of licensees in the field of preparedness. One of them is obligation to prepare and submit to SUJB the on-site emergency plan as one of attachments to his application for the licence. (The licence can be issued if defined documents, including this plan, are approved.) The licensee is obliged, under conditions given in detail in one of implementing regulation, to prepare a proposal of the emergency planning zone and submit it to SUJB. In the Act, there are also given the requirements for licensee's actions in case of a radiation emergency occurrence. On the other hand the Atomic Act names what are SUJB competencies and also what are these ones from the point of view of radiation emergency. Among others SUJB establishes the emergency planning zone, controls the activity of the National Radiation Monitoring Network, provides for the activities of an Emergency Response Centre and ensures the availability of background information necessary to take decisions aimed at reducing or averting exposure in the case of a radiation accident. SUJB has its own crisis staff; it has 4 shifts, which change regularly weekly. About 50 SUJB employees divided into 12 different functions are members of this staff. The Emergency Response Centre (ERC) of SUJB organizes work of this staff

    1986-01-01

    This paper describes the way in which the Spanish authorities have incorporated the IAEA recommendations on the planning of action to be taken in the event of a nuclear accident, taking into account the national organization's own approach to the problem of dealing with a radiation emergency. First, the criteria and principles applied in devising the emergency plans are described. The criteria are concerned with the radiation problem as such and the principles take into account the sum total of problems associated with an emergency. Organizational and operational aspects of the plan are then discussed. The extent to which these arrangements are brought into play is determined by the type of abnormal event which occurs in the facility; since the evolution of this event cannot be exactly predicted, there must be enough flexibility in the operational plan so that it can be adapted rapidly and effectively to the circumstances. Another section deals with protection measures as a function of intervention (or reference) levels. Although non-radiological considerations may affect the measures adopted, a knowledge of the risks associated with the various intervention levels gives the authority a better understanding of the situation. The Nuclear Safety Board has had to inform the civil protection authorities of the distances at which specific protection measures should be taken. Considerations and hypotheses are described which, when applied, lead to general evacuation for distances of up to 3 km from the plant, partial evacuation for up to 5 km, containment and prophylactic measures up to 10 km and water and food monitoring up to 30 km. Finally, details are given of the Training and Information Plan which is being applied at present in Spain. (author)

  20. Measuring strategy in case of a nuclear emergency situation

    In the case of a nuclear emergency situation there are other demands -compared to normal operation - of kind, availability in time and volume of information providing the description of the radiological situation and allowing the recommendation of countermeasures in time. These requirements depend on the different phases of the emergency situation and the intense operation, respectively. In the first phase e. g. even before the radioactive release starts, information from the nuclear power plant is needed besides weather forecasts, trajectories and prognoses about the expected external dose and the contamination. In addition fast available results from dose rate measurements and information about the radionuclide spectrum are necessary. The aim is to get an overview about the actual radiological situation and its possible development in time in order to introduce countermeasures, where necessary. In the second phase, short time after the distribution of the radioactive substances has stopped, measurements according to Paragraph 3 of the precautionary radiation protection law (StrVG) are of primary interest, especially the determination of the contamination of human food and animal feed. In this phase after the end of the deposition process, where the spectrum of the deposited radionuclides is known, the behaviour of the external dose as a function of time can be well predicted. In the third phase, this means weeks after the emergency situation, the measurements are used to observe the activity concentrations in different media on a long time scale. In the beginning (phase one and two) the availability of information in time is of great importance. With increasing time this shifts more and more to the diversity of the analysed media. (orig.)

    The third exercise in the INEX2 series organised under the auspices of OECD NEA was held in November 1998 in Hungary, with the participation of 4000 members of the Hungarian Emergency Response Organisation (HERO), 32 countries and 4 international organisations. The main goal of the INEX2 series was to exercise emergency preparedness activity with limited knowledge on the accident situation, to test the international notification schemes and to gain experience in informing the media and the population. The INEX2-HUN exercise assumed a medium severe accident in the Hungarian nuclear power plant with relatively high release of radioactive material that could reach also the territory of the neighbouring countries. The scenario of the accident has been elaborated by power plant experts and was played by the full scope simulator of the plant during the exercise. The nuclear emergency organisations were alerted and set up, and a full range exercise was held. The Hungarian Atomic Energy Authority (HAEA) Centre of Emergency Response Training and Analysis (CERTA) obtained on-line data from the power plant, performed source term calculations, prepared progression forecast and even analysis. The radiological monitoring network of the Emergency Information Centre (EIC) of the Secretariat to the Governmental Commission for Nuclear Emergency Preparedness (GCNEP) collected and analysed (simulated) radiological data. EIC received also the meteorological data and - making use of the source term estimates obtained from CERTA - run the specific program that gave detailed description of the radiological situation over the affected area and generated proposals to the decision-makers on the interventions to be performed. The results of the analysis and simulation were used to compile the information to be communicated to the leading organs of HERO, to the neighbouring countries and to the international community by the International Contact Point situated in the HAEA.

    Public begin to pay attention to emergency management. Thus, public's consensus on having high level of emergency management system up to advanced country's is reached. In this social atmosphere, manual is considered as key factor to prevent accident or secure business continuity. Therefore, we first define possible crisis at KEPCO Nuclear Fuel (hereinafter KNF) and also make a 'Reaction List' for each crisis situation at the view of information-design. To achieve it, we analyze several country's crisis response manual and then derive component, indicate duties and roles at the information-design point of view. From this, we suggested guideline to make 'Integrated emergency response manual(IERM)'. The manual we used before have following few problems; difficult to applicate at the site, difficult to deliver information. To complement these problems, we searched manual elements from the view of information-design. As a result, we develop administrative manual. Although, this manual could be thought as fragmentary manual because it confined specific several agency/organization and disaster type

    Based upon the experiences with the accident of Fukushima Daiichi Nuclear Power Station, Japan is now making a comprehensive review of nuclear emergency preparedness. The Nuclear Regulation Authority of Japan has changed drastically its basic concept of nuclear emergency arrangements from their dependence on the prediction methods to advance planning-oriented arrangements. In order to implement such changes in an effective enough manner, this report examines how to improve stakeholder involvement focusing on the French cases, where the Local Information Commissions (CLI) plays a critical role, and thereby derives concrete lessons for Japan. Case studies on CLI's involvement in French nuclear emergency preparedness revealed the following implications for Japan; 1. Improving continuously the disaster prevention plans of local governments and of nuclear utilities thorough recursive cycles of disaster-preparedness drill and its evaluation for the benefits of local inhabitants, 2. Setting appropriate ranges wherein local stakeholders involve constantly in establishing nuclear emergency preparedness without alienating completely other stakeholders, 3. Utilizing the prediction systems not as a means to support decision-making in emergency situations but as a tool for facilitating stakeholder involvement in the phase of advance planning, and 4. Integrating nuclear emergency preparedness into other disaster preventions for reducing complex and unrecognized risks. (author)

    The donor countries need to make decisions on various steps such as whether to fully accept newcomers’ requests, the depth of support, and how the supportive action will be carried out. Such is not an easy task due to limited time, resources, manpower, etc. Thus, creating an infrastructure to support emerging nuclear energy countries is needed. This paper suggests the resource portfolio concept used in business management and aims to analyze the validity of supporting the new entrants’ development of regulatory infrastructure as a case study. This study tries to develop a very simple Excel-based tool for assessing the supporting strategy quantitatively and screening the activities that is projected to be less effective and attractive. There are many countries, so called newcomers, which have expressed interests in developing their own nuclear power program. It has been recognized by the international community that every country considering embarking upon their own nuclear power program should establish their nuclear safety infrastructure to sustain a high level of nuclear safety. The newcomers have requested for considerable assistance from the IAEA and they already have bilateral cooperation programs with the advanced countries with matured nuclear regulatory programs. Currently, the regulatory bodies that provide support are confronted with two responsibilities as follows; the primary objective of the regulatory bodies is to ensure that the operator fulfills the responsibility to protect human health.

    The vulnerability to the disasters is high in India due to the large population density, fast growing urbanization, industrialization and also because of poor economic conditions of people. Natural disasters have been recurring phenomena in India, leading to extensive loss of life, livelihood and property. The primary reason for such heavy losses can be attributed to the reactive and response-centric approach adopted in the past in handling of the disasters. Based on the Guidelines a holistic approach is to be adopted for Nuclear Emergency Management Framework that assigns the highest priority to prevention, mitigation and compliance to regulatory requirements, while strengthening preparedness, capacity development, response etc. It will be implemented through strengthening of the existing action plans or by preparing new action plans at national, state and district levels by the stakeholders at all levels of administration

    Protective actions such as evacuation, sheltering and iodine administration can be taken to mitigate the radiological consequence in the event of an accidental release. In general, decision-making of countermeasures involves both quantitative and qualitative criteria. The conventional approaches to assessing these criteria tend to be less effective when dealing with those qualitative criteria that are imprecise or vague. In this regard, fuzzy set method is an alternative tool. It can cope with vague assessment in a better way. This paper presents the application of fussy methodology to decision-making of protective actions in nuclear emergencies. In this method linguistic terms and fuzzy triangular numbers are used to represent decision-maker's subjective assessment for different decision criteria considered and decision alternatives versus the decision criteria. Following the assessment performed by specialists, corresponding evaluations can be synthesized and ranked. Finally, the optimal strategy for implementing protective actions can be recommended.

    The pasture → milk → human exposure pathway was modelled with respect to the countermeasures in a nuclear emergency situation. The measures included feed and milk substitution by non-contaminated material, and cost-benefit analysis and uncertainty analysis was performed. Comparison of the maximum benefit of the two kinds of intervention suggests that feed substitution is superior to milk substitution. The duration of the pasture substitution depends strongly on the initial concentration of iodine-131 in the pasture. For relatively low values of activity concentration, the optimum date of withdrawing the intervention increases linearly with the logarithm of the initial radionuclide concentration in the pasture, the maximum value, however, takes nearly 40 days. For milk or feed substitution, the effect of the excess cost of early intervention reduces the maximum value of the cost-benefit function. (P.A.)

    This work was undertaken in order to develop methods and techniques for evaluating systematically and comprehensively protective action strategies in the case of a nuclear or radiation emergency. This was done in a way that the concerns and issues of all key players related to decisions on protective actions could be aggregated into decision- making transparently and in an equal manner. An approach called facilitated workshop, based on the theory of Decision Analysis, was tailored and tested in the planning of actions to be taken. The work builds on case studies in which it was assumed that a hypothetical accident in a nuclear power plant had led to a release of considerable amounts of radionuclides and therefore different types of protective actions should be considered. Altogether six workshops were organised in which all key players were represented, i.e., the authorities, expert organisations, industry and agricultural producers. The participants were those responsible for preparing advice or presenting matters for those responsible for the formal decision-making. Many preparatory meetings were held with various experts to prepare information for the workshops. It was considered essential that the set-up strictly follow the decision- making process to which the key players are accustomed. Key players or stakeholders comprise responsible administrators and organisations, politicians as well as representatives of the citizens affected and other persons who will and are likely to take part in decision-making in nuclear emergencies. The realistic nature and the disciplined process of a facilitated workshop and commitment to decision-making yielded up insight in many radiation protection issues. The objectives and attributes which are considered in a decision on protective actions were discussed in many occasions and were defined for different accident scenario to come. In the workshops intervention levels were derived according justification and optimisation

    Ringhals has been a model for this study, but the purpose has been to make the report applicable at all nuclear power plants in Sweden. The work has been done in close co-operation with the Swedish nuclear power plants and Rescue Services in the nuclear power municipalities Oesthammar, Oskarshamn, and Varberg. The internal fire brigade at the nuclear power plants has also been involved. A document will also be published as a further guidance at efforts of the type fires, which are mentioned in the enclosed document. After a fire in a switchgear room in 2005 the need of making the existing effort planning more effective at nuclear power plants was observed. The idea with the planning is to plan the effort in order to give the operational and emergency staff a good and actual support to come to a decision and to start the mission without delay. The risk information is showed by planning layouts, symbols and drawings as basis, give risk information and effort information. The effort information shows outer arrangements, manual action points, fire installations, passive fire safety etc. The risk information is shown by risk symbols. Their purpose is to give a fast overview of the existing risks. Reactor safety effects is the ruling influence if an effort has to be done in order to secure safety for a third person. In order to make an effort in an area personal risks for rescue staff, such as electricity risks, radiological risks, chemicals and gas bottles with compressed gases, has to be eliminated. For complicated missions detailed instructions are needed in order to handle specific risks. In a group discussion different people with pertinent knowledge has to value which problematic efforts need detailed instruction. Missions that have to be analyzed in a work group as above are: fire may affect the reactor safety, fire that may threaten the structural integrity, chemical discharge with big consequence on environment/third person and handling of gas system (compressed

    The lessons learned from the Fukushima Daiichi accident have focused on preventive measures designed to protect nuclear reactors, and crisis management plans. Although there is still no end in sight to the accident that occurred on March 11, 2011, how engineers have handled the aftermath offers new insight into the capacity of organizations to adapt in situations that far exceed the scope of safety standards based on probabilistic risk assessment and on the comprehensive identification of disaster scenarios. Ongoing crises in which conventional resources are lacking, but societal expectations are high, call for "engineering thinking in emergency situations." This is a new concept that emphasizes adaptability and resilience within organizations-such as the ability to create temporary new organizational structures; to quickly switch from a normal state to an innovative mode; and to integrate a social dimension into engineering activities. In the future, nuclear safety oversight authorities should assess the ability of plant operators to create and implement effective engineering strategies on the fly, and should require that operators demonstrate the capability for resilience in the aftermath of an accident.

    According to the individual feature identification method and combining with the characteristics of nuclear accident emergency decision-making, the evaluation index system of the nuclear accident emergency decision-making was determined on the basis of investigation and analysis. The effectiveness of the nuclear accident emergency decision-making was evaluated based on the individual standards by solving the individual features of the individual standard identification decisions. The case study shows that the optimization result is reasonable, objective and reliable, and it can provide an effective analysis method and decision-making support for optimization of nuclear accident emergency protective measures.

    Full text: The IRSN has been organizing enquiries with the French population about risk and risk perception for a long time. In 2002, a collaboration between the IRSN in France and the SCK.CEN in Belgium has been set-up to simultaneously (November 2002) organise this poll in both countries. In each country, a representative sample of the population (over 1000 participants per country) has been consulted by Computer Aided Personal Interviews of about 30 minutes with the professional help of commercial companies: BVA in France and Research International in Belgium. The enquiry yields a broad spectrum of interesting data; here only the results relevant for the emergency context will be presented. One should be aware that these data were collected in a 'normal' period; important differences in behaviour may occur given a serious crisis. A first finding is that more than half of the respondents are convinced that an accident as severe as the Chernobyl disaster may happen in their country as well. A large majority believes that the authorities would not be capable of coping with the consequences of a nuclear accident; many people do not know whether there is an emergency organization in place or not. These data reveal some distrust in the nuclear technology, a fear for the magnitude of consequences of an accident, and a lack of confidence in the capabilities of the authorities. Despite of the European directive 89/618/Euratom an informing the general public about health protection measures to be applied and steps to be taken in the event of a radiological emergency, and the initiatives in both countries resulting from it, the general feeling about the information received is fairly negative to negative, even worse in Belgium as compared to France. A closer look to the Belgian data reveals a better appreciation in the proximity of the main nuclear facilities, where a more intense information campaign has been organized fairly recently and where more information via the

    The nuclear emergency preparedness and response have comprehensively been developed over ten years in China. In order to promote the sound development of emergency preparedness and response, it is useful to retrospect the process of emergency preparedness and response, to summarize the experiences and absorb the experiences from foreign countries. The main issues are as follows: 1) The preparedness and response to nuclear and radiological accident is basically the same as the response to any accident involving hazardous material. 2) The classification of emergency planning, not only for nuclear facilities, but also irradiation installation, etc. 3) The hazard assessment-- a top priority. 4) The emergency planning zones. 5) Psychological impact

    Nuclear power plant emergency command system can provide valuable data for emergency personnel, such as the unit data, weather data, environmental radiation data. In the course of emergency response, the emergency command system provides decision support to quickly and effectively control and mitigate the consequences of the nuclear accident, to avoid and reduce the dose received by staff and the public, to protect the environment and the public. There are high performance requirements on the security of the system and the data transmission. Based on the previous project and new demand after the Fukushima incident, the security technology design of emergency system in nuclear power plant was discussed. The results show that the introduction of information security technology can effectively ensure the security of emergency systems, and enhance the capacity of nuclear power plant to deal with nuclear accidents.

    This research was carry out due to the low presence of PET/CT projects in Venezuela in this moment, which consisted of the implementation and evaluation of a protocol for the acceptance and implementation of a hybrid tomograph PET/CT Discovery ST located in the nuclear medicine service at the Hospital de Clinicas Caracas. For this work, two references were used to provide a basic set of tests established and accepted by almost all manufacturers, such references are: NEMA 1994 PET and Spanish Protocol for Quality Control for Radiology CT. In general, we found that the smallest lesion in a functional image that this tomograph can resolve is {approx} 6mm. The spatial resolution of an anatomical image was resolved through 8 pl/cm. Likewise, this tomograph is able to produce a uniform anatomical and functional image, with very little noise and radiation scattered once the correction was done, referring to the test of co-registration accuracy of PET and CT shows that there is an excellent correspondence between the image of PET (functional) and the image of CT (anatomic), a basic parameter in a study of PET/CT.

    It was clear from the accident at Fukushima Dai-ichi in Japan in March 2011 that national assessment and responses to nuclear emergencies even if at a great distance from Europe could be significantly improved by a more rapid exchange of information. Discussions on this point during the 7. HERCA Board of Heads meeting in June 2011 led to the 'Working Group Emergencies' (WGE) being tasked with reviewing the issues and proposing practical working solutions for a more harmonized approach in response to such distant nuclear and radiological emergency situations. The present report is the result of that work. The aim of the report is on the one hand to assist radiological safety authorities to improve their preparedness in some areas and, on the other hand, to provide an overview of the important radiological issues to be considered by radiation protection authorities in the event of a nuclear or radiological emergency in a distant country

    Decision support systems for nuclear emergency management (DSNE) are currently used worldwide to assist decision makers in taking emergency response countermeasures in case of accidental releases of radioactive materials from nuclear facilities. The present work has been motivated by the fact that, up until now, DSNE systems have not been regarded as safetycritical software systems, such as embedded software currently being used in vehicles and aircraft. The core of any DSNE system is represented by the different simulation codes linked together to form the dispersion simulation workflow. These codes require input emission and meteorological data to produce forecasts of the atmospheric dispersion of radioactive pollutants and other substances. However, the reliability of the system not only depends on the trustworthiness of the measured (or generated) input data but also on the reliability of the simulation codes used. The main goal of this work is to improve the reliability of DSNE systems by adapting current state of the art methods from the domain of software reliability engineering to the case of atmospheric dispersion simulation codes. The current approach is based on the design by diversity principle for improving the reliability of codes and the trustworthiness of results as well as on a flexible fault-tolerant workflow scheduling algorithm for ensuring the maximum availability of the system. The author's contribution is represented by (i) an acceptance test for dispersion simulation results, (ii) an adjudication algorithm (voter) based on comparing taxonomies of dispersion simulation results, and (iii) a feedback-control based fault-tolerant workflow scheduling algorithm. These tools provide means for the continuous verification of dispersion simulation codes while tolerating timing faults caused by disturbances in the underlying computational environment and will thus help increase the reliability and trustworthiness of DSNE systems in missioncritical

    In nuclear industry the routing in case of any emergency is a cause of concern and of great importance. Even the smallest of time saved in the affected region saves a huge amount of otherwise received dose. Genetic algorithm an optimization technique has great ability to search for the optimal path from the affected region to a destination station in a spatially addressed problem. Usually heuristic algorithms are used to carry out these types of search strategy, but due to the lack of global sampling in the feasible solution space, these algorithms have considerable possibility of being trapped into local optima. Routing problems mainly are search problems for finding the shortest distance within a time limit to cover the required number of stations taking care of the traffics, road quality, population size etc. Lack of any formal mechanisms to help decision-makers explore the solution space of their problem and thereby challenges their assumptions about the number and range of options available. The Genetic Algorithm provides a way to optimize a multi-parameter constrained problem with an ease. Here use of Genetic Algorithm to generate a range of options available and to search a solution space and selectively focus on promising combinations of criteria makes them ideally suited to such complex spatial decision problems. The emergency response and routing can be made efficient, in accessing the closest facilities and determining the shortest route using genetic algorithm. The accuracy and care in creating database can be used to improve the result of the final output. The Genetic algorithm can be used to improve the accuracy of result on the basis of distance where other algorithm cannot be obtained. The search space can be utilized to its great extend

    This paper has a twofold objective. One is to analyze the current status of high-level nuclear waste disposal along with presentation of practical perspectives about the environmental issues involved. Present disposal designs and concepts are analyzed on a scientific basis and modifications to existing designs are proposed from the perspective of environmental safety. Other is to understand the aerosol formation in the atmosphere for the case of the leakage from the nuclear waste containers or a nuclear accident. Radio-nuclides released from the waste will attach themselves to the existing aerosols in the atmosphere along with formation of new aerosols. Anticipating the nuclear accident when a variety of radioactive aerosols will form and exist in the atmosphere, as a simple example, measurement of naturally existing radioactive aerosols are made in the atmosphere of Islamabad and Murree. A comparison with similar measurements in 3 cities of France is provided. Measurement of radionuclides in the atmosphere, their attachment to aerosols and follow up transport mechanisms are key issues in the nuclear safety. It is studied here how "7Be concentration in the atmospheric air varies in the capital city of Islamabad and a Himalaya foothill city of Murree (Pakistan). Present results are compared with recent related published results to produce a "7Be concentration versus altitude plot up to an altitude of 4000 m (a.s.l.). Origin and variance of "7Be concentration at different altitudes is discussed in detail. The relevance of results presented here with the evaluation of implications of Chernobyl and Fukushima nuclear disasters has been discussed in a conclusive manner. It is the first international report of a joint collaboration/project. The project is being generalized to investigate and formulate a smooth waste storage and disposal policy. The project will address the fission and fusion waste reduction, its storage, its recycling, air, water and soil quality

  14. Preparation, conduct and evaluation of exercises to test preparedness for a nuclear or radiological emergency. Emergency preparedness and response

    International Nuclear Information System (INIS)

    2005-04-01

    The aim of this publication is to serve as a practical tool for the preparation, conduct and evaluation of exercises to test preparedness for response to a nuclear or radiological emergency. It fulfils in part the functions assigned to the IAEA under Article 5.a(ii) of the Convention on Assistance in Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), namely, to collect and disseminate to States Parties and Member States information concerning the methodologies, techniques and available results of research on such emergencies. To ensure effective response to radiation emergencies when needed, provisions should be made for regular training of emergency response personnel. As stated in Preparedness and Response for a Nuclear or Radiological Emergency (Safety Requirements, Safety Standard Series No. GS-R-2), 'The operator and the response organizations shall make arrangements for the selection of personnel and training to ensure that the personnel have the requisite knowledge, skills, abilities, equipment, procedures and other arrangements to perform their assigned response functions'. A further requirement is that 'Exercise programmes shall be conducted to ensure that all specified functions required to be performed for emergency response and all organizational interfaces for facilities in threat category I, II or III and the national level programmes for threat category IV or V are tested at suitable intervals'. In 2004 the IAEA General Conference, in resolution GC(48)/RES/10 encouraged Member States to 'implement the Safety Requirements for Preparedness and Response to a Nuclear or Radiological Emergency'. This document is published as part of the IAEA Emergency Preparedness and Response Series to assist in meeting these requirements and to fulfil Article 5 of the Assistance Convention. It was developed based on a number of assumptions about national and local capabilities. Therefore, the exercise structure, terms and scenarios must be

    We conducted a group interview survey for 24 persons living in urban areas of the Kansai region to understand the change in their perception of information about nuclear emergency plans for nuclear power stations. The participants were given descriptions about a nuclear emergency plan based on plans that had been prepared by the national government and local government. Before hearing the explanation about the nuclear emergency plan, we found that only a few participants were concerned about it, but no one knew the detailed contents. For the question 'Do you think the nuclear emergency plan is being improved after the Fukushima Daiichi Nuclear Power Plant accident?', we found 6 persons among the 24 held opinions saying that the plan was 'improved' or 'somewhat improved'. However, after hearing the explanation and a brief Q and A session about it, 18 persons held opinions saying the plan was 'improved' or 'somewhat improved'. As the reason for such answers, the most common opinion shared by 13 persons was that 'a nuclear emergency plan is being made'. There is a possibility that urban residents had not known the facts about specific disaster prevention plans for each nuclear power station that have been formulated. (author)

  16. Method for Developing a Communication Strategy and Plan for a Nuclear or Radiological Emergency

    International Nuclear Information System (INIS)

    2016-01-01

    The aim of this publication is to provide a practical resource for emergency planning in the area of public communication in the development of a radiation emergency communication plan (RECP). The term 'public communication' is defined as any activity that communicates information to the public and the media during a nuclear or radiological emergency. To avoid confusion, the term public communication has been used in this publication rather than public information, which may be used in other IAEA publications and documents to ensure consistency with the terminology used in describing the command and control system. This publication also aims to fulfil in part functions assigned to the IAEA in the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), as well as meeting requirements stated in IAEA Safety Standards Series No. GS-R-2, Preparedness and Response for a Nuclear or Radiological Emergency. Under Article 5(a)(11) of the Assistance Convention, one function of the IAEA is to collect and disseminate to States Parties and Member States information concerning methodologies, techniques and results of research with regard to the response to nuclear or radiological emergencies. This publication is intended to provide guidance to national and local authorities on developing an RECP which incorporates the specific functions, arrangements and capabilities that will be required for public communication during a nuclear or radiological emergency. The two main features of this publication are the template provided to develop an RECP and detailed guidance on developing a communication strategy for emergency preparedness and response to nuclear or radiological emergencies. The template is consistent with the outline of the national radiation emergency plan proposed in Method for Developing Arrangements for Response to a Nuclear or Radiological Emergency (EPR-Method 2003).

    The Canadian Forces have established Nuclear Emergency Response Teams to cope with potential radiation accidents. Previously, only gamma and high-energy beta radiation could be detected. Recently, new radiation sampling, detecting, and analytical equipment has been bought, including air samplers, beta counters, high-purity germanium gamma detectors, and multi-channel analyzers together with Gamma Vision Software to analyze gamma spectra. The purpose of the present study is to propose a way to use the new equipment, to analyze the results from the gamma and beta detectors, and to integrate the results into a format for decision making. Integration is achieved through the creation of a computer program, Radiation Integration Program (RIP). This program analyzes gross beta counts, and uses them to estimate danger to the thyroid. As well the results from Gamma Vision are converted from Bq to dose rate for several parts of the body. Overall gamma results affecting the thyroid are compared to the beta results to verify the initial estimations.

    Full text: In the event of a nuclear emergency in an urban environment a reliable overview on the radioactive contamination is crucial for decision making. To assess the radiological situation both measurements of the gamma dose or dose rate (GDR) and results from urban dispersion and deposition models are used. Measurements may arrive from various sources like car-borne detectors or man-borne radiation-sensitive materials embedded in cell phones, flash memory devices or RFID chips. The measurements depend strongly on the detector environment. To account for this dependence each signal is multiplied by a location factor, which quantifies the deviation of the recorded signal from the hypothetical signal of a reference surface of infinitely extended lawn. Furthermore, the data originate from geo-referenced points or lines but do not provide full spatial information. We present here two approaches to produce maps of the reference GDR or surface contamination in urban areas, which are implemented in the Inhabited Areas Monitoring Module (IAMM) as part of the European decision support systems RODOS and ARGOS. Immediately after the accident, a few measurements are combined with the predictions of urban models using data assimilation. If enough measurements are available they are regionalised with geo-statistical interpolation algorithms like inverse distance weighting or kriging. Both approaches are demonstrated in hypothetical scenarios based on the explosion of a radioactive dispersion device. (author)

    In the present thesis, the software DERA (Dispersion of Radioactive Effluents into the Atmosphere) was developed in order to calculate the equivalent dose, external and internal, associated with the release of radioactive effluents into the atmosphere from a nuclear facility. The software describes such emissions in normal operation, and not considering the exceptional situations such as accidents. Several tools were integrated for describing the dispersion of radioactive effluents using site meteorological information (average speed and wind direction and the stability profile). Starting with the calculation of the concentration of the effluent as a function of position, DERA estimates equivalent doses using a set of EPA s and ICRP s coefficients. The software contains a module that integrates a database with these coefficients for a set of 825 different radioisotopes and uses the Gaussian method to calculate the effluents dispersion. This work analyzes how adequate is the Gaussian model to describe emissions type -puff-. Chapter 4 concludes, on the basis of a comparison of the recommended correlations of emissions type -puff-, that under certain conditions (in particular with intermittent emissions) it is possible to perform an adequate description using the Gaussian model. The dispersion coefficients (σ{sub y} and σ{sub z}), that using the Gaussian model, were obtained from different correlations given in the literature. Also in Chapter 5 is presented the construction of a particular correlation using Lagrange polynomials, which takes information from the Pasquill-Gifford-Turner curves (PGT). This work also contains a state of the art about the coefficients that relate the concentration with the equivalent dose. This topic is discussed in Chapter 6, including a brief description of the biological-compartmental models developed by the ICRP. The software s development was performed using the programming language Python 2.7, for the Windows operating system (the

    The use of nuclear technology has been widely employed and will continue to expand in use in Nigeria particularly in the health, industrial, mining, water resources, agriculture, manufacturing, education and research sectors. Incidents and emergencies cannot therefore be ruled out. Effective national response capabilities are essential to minimize the impacts from nuclear and radiological emergencies, and to build public trust in the safety and security of nuclear technology. The often discussed Nigeria's Nuclear Power Plant (NPP) project cannot occur without enhanced national capabilities to respond to an incidence or emergency. Moreover, increased concern over the use of nuclear or radioactive materials malevolent acts increases the need to broaden response capabilities. This paper examines Nigeria's status on capabilities for response to a nuclear and radiological emergency vis-a-vis international requirements for effective response capabilities

    Full text: Responsibilities Regarding Emergency Response in Germany - In the Federal Republic of Germany, the 16 federal state Ministries of the Interior are responsible for emergency response (threat through weapons, explosives, etc.). In the case of threats due to radioactive material experts of the competent federal state radiological protection authorities are consulted. The Federal Office for Radiation Protection assists in serious cases of defence against nuclear hazards (nuclear fuels, criticality, risk of dispersion). Currently, exercises are being performed in all 16 federal states to co-ordinate the ways of behaviour, action and thinking of the various necessary organisational units, like police, deactivators, prosecution officials, radiological protection experts and fire brigade. The joint exercises serve the purpose to practice the total chain of necessary measures like: notification chain, organisation at the place of action, co-ordination of appropriate search strategy, investigation of who was responsible, analysis (X-ray pictures, radiological analysis), activity determination, assessment of possible effects due to deactivation measures, determination of dispersion conditions, recommendation of measures for the protection of responders and the general population and measures to limit the consequences. Given Exercise Scenario - Via the emergency emergency call a situation is transmitted that urgently demands joint and co-ordinated action of prosecution authority, emergency response and radiation protection authority, to be able to master the situation successfully. As a rule this means that one deals with an IED (Improvised Explosive Device) secured by a booby trap with added radioactive substances. Organisation at the Place of Action - Experience shows that as a rule the patrol police and the local fire brigade will be the first to arrive at the place of action, already after a few minutes. Gradually, the other experts arrive. Depending on distance

    With respect to Chernobyl accident the changes in understanding of nuclear emergency preparedness have initiated a developing process resulting in an effective enhancement of conditions ensuring adequate response to nuclear or radiological accidents of emergency situations in many countries. The Slovak Nuclear Regulatory Authority (UJD) in frame of co-operations with IAEA, EC, OECD/NEA and other international organisations has actively participated in this challenging work targeting implementation of international experience and best practices in the country. The new international policy (principles declared e.g. in 'Memorandum of Understanding', IAEA, Vienna, 1997) based on experiences propagating importance of regional co-operation, harmonised approach and clear strategy for protective measures implementation in case of a nuclear or radiological accident has influenced the development also in Slovakia. The implementation process in the country was supported by changes in legal conditions regulating peaceful use of nuclear energy [1,2] including basic rules for emergency preparedness published in the second half of 1990 years. The principles of emergency preparedness in Slovakia fully support regional harmonisation and co-operation. Effective implementation of international practice and sharing of experience substantially contributed to the level of emergency response in the country and to the harmonisation of emergency response preparedness creating also conditions for an efficient regional integration.

    International Nuclear Information System (INIS)

    2001-01-01

    Recommendations of the Nordic radiation protection authorities on application of international criteria in a nuclear or radiological emergency in the Nordic countries are presented. The recommendations are focused on the generic intervention levels for various actions to protect members of the public and workers undertaking an intervention. Prompt precautionary actions for the near zones around the Finnish and Swedish nuclear power plants are defined. These actions are; preventive sheltering, iodine prophylaxis and precautionary evacuation. No special intervention levels for these precautionary actions have been set, because implementation of these actions is always based on very limited information about an accident. These actions can be initiated on a mere indication of possible release of radioactivity. The indication might be an alarm or any other predefined signal. Intervention level for actions to protect members of the public are based on the concept of avertable dose. They are in line with the international recommendations. With regard to iodine prophylaxis, a national approach is recommended due to different national policies of advance distribution of iodine tablets. The longer term intervention actions, temporary relocation and permanent resettlement, will be based not only on radiation protection factors but also on wider judgement of the overall situation. For that reason, no generic intervention levels, in terms of radiation dose, are recommended. The intervention levels for various protective actions are in the following table.Table 1. Generic intervention levels for actions to protect members of the public.Protective action. Generic intervention level as an avertable dose. Sheltering: 10 mSv within two days (effective dose); Iodine prophylaxis: National recommendations; Evacuation: 50 mSv within one week (effective dose); Temporary relocation: No predetermined intervention level; Permanent resettlement: No predetermined intervention level.

    Regulatory Policy is formulated in regulations that stipulate the assurance of workers and public safety and environmental protection. Legislation and regulations on nuclear energy should consider nuclear safety, security and safeguards, as well as nuclear emergency preparedness (3S+EP) and liability for nuclear damage. Specific requirements stipulated in international conventions and agreements should also be taken into account. Regulatory Policy is formulated in regulations that stipulate the assurance of workers and public safety and environmental protection. Legislation and regulations on nuclear energy should consider nuclear safety, security and safeguards, as well as nuclear emergency preparedness (3S+EP) and liability for nuclear damage. Specific requirements stipulated in international conventions and agreements should also be taken into account. By undertaking proper regulatory oversight on Safety, Security and Emergency Preparedness (3S+EP) as an integrated and comprehensive system, safe and secure use of nuclear energy can be assured. Licence requirements and conditions should fulfil regulatory requirements pertaining to 3S+EP for nuclear installation as an integrated system. An effective emergency capacity that can be immediately mobilized is important. The capacity in protecting the personnel before, during and after the disaster should also be planned. Thus, proper emergency preparedness should be supported by adequate resources. The interface between safety, security, safeguards and emergency preparedness has to be set forth in nuclear regulations, such as regulatory requirements; 3S+EP; components, systems and structures of nuclear installations and human resources. Licensing regulations should stipulate, among others, DIQ, installations security system, safety analysis report, emergency preparedness requirements and necessary human resources that meet the 3S+EP requirements.

    1995-01-01

    Some 20 yr ago a hand-held slide rule was developed at the Oak Ridge Y-12 Plant to aid in the response to several postulated nuclear criticality accidents. These assumed accidents involved highly enriched uranium in either a bare metal or a uranyl nitrate system. The slide rule consisted of a sliding scale based on the total fission yield and four corresponding dose indicators: (1) a prompt radiation dose relationship as a function of distance; (2) a delayed fission product gamma dose rate relationship as a function of time and distance; (3) the total dose relationship with time and distance; and (4) the I-min integrated dose relationship with time and distance. The original slide rule was generated assuming very simplistic numerical procedures such as the inverse-square relationship of dose with distance and the Way-Wigner relationship to express the time dependence of the dose. The simple prescriptions were tied to actual dose measurements from similar systems to yield a meaningful, yet simple approach to emergency planning and response needs. This paper describes the application of an advanced procedure to the updating of the original slide rule for five critical systems. These five systems include (a) an unreflected sphere of 93.2 wt% enriched uranium metal, (b) an unreflected sphere of 93.2 wt% enriched uranyl nitrate solution with a H/ 235 U ratio of 500, (c) an unreflected sphere of damp 93.2 wt% enriched uranium oxide with a H/ 235 U ratio of 10, (d) an unreflected sphere of 4.95 wt% enriched uranyl fluoride solution having a H/ 235 U ratio of 410, and (e) an unreflected sphere of damp 5 wt% enriched uranium dioxide having a H/ 235 U ratio of 200

    The continuous use of nuclear power to generate electricity and the continued threat of radioactive materials being used for nefarious reasons reminds us of the importance to stay prepared to respond to nuclear or radiological emergencies. Stringent nuclear safety and nuclear security requirements, the training of personnel, operational checks and legal frameworks cannot always prevent radiation-related emergencies. Though these events can range in severity, each has the potential to cause harm to the public, employees, patients, property and the environment. Until the Chernobyl nuclear accident in 1986, there was no international information exchange system. Immediately following that accident, the international community negotiated the so-called Emergency Conventions to ensure that the country suffering an accident with an international transboundary release of radioactive material would issue timely, authenticated information, while the States that could field technical support, would do so in a coordinated fashion. The Conventions also place specific legal obligations on the International Atomic energy Agency (IAEA) with regard to emergency preparedness and response. (Author)

    Full text: In the year 1998, with the regulation of the Nuclear Law, the Nuclear Regulatory Authority (ARN) is constituted as the national coordinator of the response in case of nuclear or radiological emergencies. The ARN builds his first operative center installed in his Head quarter in Buenos Aires. Likewise, from the obligations that come with the Convention of Early Notification of a Nuclear Accident and Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency, the ARN is the National Warning Point and the National Competent Authority. Therefore, the operative capacity of the center needs to be expanded to cover not only the national territory but also its link with the region and the IAEA, as an access point to the International community, as the conventions demand. For the purpose of giving ARN capacities which reflect the state of art at the international level on Nuclear Emergency Centers and warrant that its equipment and technology will be compatible with those abroad (mainly with IAEA), the ARN made an arrangements with Department of Energy of United States, in the framework of an existing bilateral Argentine Foreign Office/US Government agreement (Joint Standing Committee on Nuclear Cooperation). This agreement allows a deep experience exchange, high level specialists support and last generation equipment access. As a result, the center of ARN can be considerate as the most advanced civil nuclear emergency center in the region. This work describes the implementation process of the emergency center and the technical features, like the physical distribution, hardware and software resources, communication equipment, Geographic Information Systems, etc. (author)

    This report summarizes the emergency plans for accidents at nuclear power plants in Germany, Sweden, Switzerland, the United Kingdom, Canada, and France. Soviet Union documents were examined, but no published information was found on the subject. The study of foreign plans was to determine what U.S. planners might learn that could be useful to them. Plans of the foreign countries were published before the nuclear accident at Three Mile Island and reflected a generally accepted premise that a serious nuclear emergency would never occur. Therefore, there are few ideas of immediate use to U.S. planners. Most countries have since begun to re-examine their emergency planning. The study also discusses the emergency action levels, warning systems, evacuation management and procedures, and public information and education for people living near nuclear power plants and defines roles of nuclear facility operators and roles of the government.

    The OECD Nuclear Energy Agency (Nea) has a long tradition of expertise in the area of nuclear emergency policy, preparedness, and management. The 1986 Chernobyl accident demonstrated that nuclear accidents may have consequences over wide areas, highlighting the need for international cooperation, coordination and communication. From the beginning, the Nea focus of work, as carried out by the Working Party on Nuclear Emergency Matters, has been on improving the effectiveness of international nuclear emergency preparedness and management. A major pillar of this work has been the preparation and organisation of the International Nuclear Emergency Exercise (I.N.E.X.) series. Beginning in 1993, the Nea I.N.E.X. series has proved successful in testing and developing arrangements for nuclear emergency response. The I.N.E.X.-1,-2 and -2000 series, which focussed on the early-phase of an emergency, provided a unique forum for testing existing as well as new arrangements and concepts for international nuclear emergency management, and succeeded in establishing a recognised international nuclear emergency exercise culture. In response to international interest in the longer term consequence management issues that will arise after an emergency, the Nea developed a third generation of exercises, I.N.E.X. 3. The I.N.E.X. 3 series of national level table-top exercises focused on the response to widespread radiological contamination of the environment and the issues likely to be raised in the medium to longer term period after such an event. Exercise objectives included an investigation of decisions on agricultural countermeasures and food restrictions, countermeasures such as travel and trade, recovery management and public information. The evaluation aimed to identify aspects of national decision-making which would benefit from international co-ordination, compare national approaches and identify 'best' practices in these circumstances.

    Nuclear emergency exercises are considered to make an important contribution to the efficiency of emergency preparedness. Generally, the details of the emergency exercises are specified for each country and often for each site, reflecting the particular features that exist in relation to general emergency arrangements. The Chernobyl accident brought a new dimension into the arena of emergency arrangements - the international dimension. New conventions and revised international guidance have been issued and have been or are being included in national emergency plans. The OECD Nuclear Energy Agency decided in 1990 to promote international co-operation in the field of emergency exercises and has adopted a programme of work in this field. One component of this programme, which concerns a survey on national practices and lessons learnt from the planning and conduct of emergency exercises, is dealt with in this paper

    The successful mastering of every emergency situation is based on the strict adherence to frequently reviewed emergency instruction and practice on simulators. This is the primary duty of all plant employees. In addition, executive bodies are necessary. The highest authority in the emergency organization is the emergency staff. Under the leadership of the plant manager, this staff consists of all department heads and several specialists. Outside normal working hours, it can be expected of the emergency staff that it is fully functional within, at most, one hour. Until the emergency staff can take over, the on-duty engineer leads emergency procedures. Several other different teams are responsible to the emergency staff. There are five emergency teams: off-duty plant employees; fire fighters; radiation defence; first-aid; plant guards. Then there is the technical support center (TSC). The responsibilities of the TSC are: giving technical advise to the emergency staff; working out different options for fighting the emergency; checking up on special methods; communication with the reactor manufacturer for additional support. 1 fig

    The Fukushima nuclear power plant accident occurred on March 11, 2011, when two natural disasters of unprecedented strengths, an earthquake with magnitude 9 followed one hour later by a powerful tsunami struck northeastern Japan and felled the external power supply and the emergency diesel generators of the Fukushima Daiichi nuclear power station, resulting in a loss of coolant accident. There were core meltdowns in three nuclear reactors with the release of radioactivity estimated to be 1/10 of what was released to the environment during the Chernobyl nuclear power plant accident in April 1986. The Fukushima nuclear accident tested the capability of the Philippine Nuclear Research Institute (PNRI) and the National Disaster Risk Reduction and Management Council (NDRRMC) in responding to such radiological emergency as a nuclear power plant accident. The PNRI and NDRRMC activated the RADPLAN for possible radiological emergency. The emergency response was calibrated to the status of the nuclear reactors on site and the environmental monitoring undertaken around the site and off-site, including the marine environment. This orchestrated effort enabled the PNRI and the national agencies concerned to reassure the public that the nuclear accident does not have a significant impact on the Philippines, both on the health and safety of the people and on the safety of the environment. National actions taken during the accident will be presented. The role played by the International Atomic Energy Agency as the central UN agency for nuclear matters will be discussed. (author)

    The GERT random network model of nuclear power accident emergency was built in this paper, and the intelligent computation was combined with the random network based on the analysis of Fukushima nuclear accident in Japan. The emergency process was divided into the series link and parallel link, and the parallel link was the part of series link. The overall allocation of resources was firstly optimized, and then the parallel link was analyzed. The effect of the resources for emergency used in different links was analyzed, and it was put forward that the corresponding particle velocity vector was limited under the condition of limited emergency resources. The resource-constrained particle swarm optimization was obtained by using velocity projection matrix to correct the motion of particles. The optimized allocation of resources in emergency process was obtained and the time consumption of nuclear power accident emergency was reduced. (authors)

    The site of the gas-cooled reactor with direct-circuit gas turbine is preferably the sea coast. An emergency cooling system with safety valve and emergency feed-water addition is designed which affects at least a part of the reactor core coolant after leaving the core. The emergency cooling system includes a water emergency cooling circuit with heat exchanger for the core coolant. The safety valve releases water or steam from the emergency coolant circuit when a certain temperature is exceeded; this is, however, replaced by the emergency feed-water. If the gas turbine exhibits a high and low pressure turbine stage, which are flowed through by coolant one behind another, a part of the coolant can be removed in front of each part turbine by two valves and be added to the haet exchanger.

    For an effective emergency response and implementation of counter measures, communication during a nuclear emergency is a very important aspect. The declaration of a nuclear emergency must be immediately conveyed to all those working in the plant and around the nuclear site. Besides this, the nature of emergency also needs to be conveyed unambiguously along with corresponding counter measures, such as stay in, evacuation or all clear signal for the relevant plants. This requirement has necessitated the need for a networked signaling system. Based on this requirement, a microcontroller based signaling and a telephone/wireless based communication and display system has been designed at Bhabha Atomic Research Centre. It is proposed to be used as a part of emergency preparedness and response programme at the nuclear facility sites. As per the design made for Bhabha Atomic Research Centre, Trombay site, each plant or area in the site is identified by a unique identification code. The main Site Emergency Control Centre/Emergency Response Centre at Mod. Labs. selectively calls the various plants and declares the nature of emergency to be followed In that plant/area through different siren signals along with display and announcement of instructions. This paper describes the details of the system that is designed for Bhabha Atomic Research Centre, Trombay site and proposed for other nuclear power plant sites. (author)

    Based on federal acts and a specific guideline of the nuclear authority ENSI, strict requirements are imposed on emergency exercises at Swiss NPPs. The Beznau NPP has conducted emergency exercises for more than 30 years. Systematic exercise planning assures that all emergency cases defined in the plant-specific emergency plan are considered in the exercise scenarios. Technically oriented scenarios cover all groups of initiating events and all safety levels of the defense in depth principle. The exercise results are an important input for optimization measures in the areas of emergency organization, documentation and infrastructure. Due to the goal-oriented enforcement of laws and guidelines by the nuclear authority ENSI, emergency exercises serve as a motor of further optimization of emergency preparedness. (orig.)

    The evaluation of the critical nuclear infrastructure vulnerability to threats like human occurrences, terrorist attacks and natural disasters and the preparation of emergency response plans with the estimation of optimized costs are of the vital importance for the assurance of a safe nuclear facilities operation and the national security. In the past national emergency systems did not include vulnerability assessments of the critical nuclear infrastructure as the important part of the comprehensive preparedness framework. The fundamental aims of the efficient emergency preparedness and response system are to provide a sustained emergency readiness and to prevent an emergency situation and accidents. But when an event happens the mission is to mitigate consequences and to protect the people and environment against the nuclear and radiological damage. The efficient emergency response system, which would be activated in the case of the nuclear and/or radiological emergency and release of the radioactivity to the environment, is an important element of a comprehensive system of the nuclear and radiation safety. In the article the new methodology for the critical nuclear infrastructure vulnerability assessment as a missing part of an efficient emergency preparedness system is presented. It can help the overall national energy sectors to identify and better understand the terrorist threats and vulnerabilities of their critical infrastructure. The presented methodology could also facilitate national agencies to develop and implement a vulnerability awareness and education programs for their critical assets to enhance the security, reliability and safe operation of the whole energy infrastructure. The vulnerability assessment methodology will also assist nuclear power plants to develop, validate, and disseminate the assessment and survey of new efficient countermeasures. The significant benefits of the new vulnerability assessment research are to increase nuclear power

    1986-01-01

    This research work examines the social construction of the nuclear-safety institution in France, and the concurrent increased focus on the nuclear-risk issue. Emphasis on risk and safety, as primarily technical issues, can partly be seen as a strategy. Employed by power elites in the nuclear technostructure, this diverts emphasis away from controversial and normative questions regarding the political and social consequences of technology to questions of technology that appear to be absolute to the technology itself. Nuclear safety, which started from a preoccupation with risk related to the nuclear energy research and development process, is examined using the analytic concept of field. As a social arena patterned to achieve specific tasks, this field is dominated by a body of state engineers recognized to have high-level scientific and administrative competences. It is structured by procedures and administrative hierarchies as well as by technical rules, norms, and standards. These are formalized and rationalized through technical, economic, political, and social needs; over time; they consolidate the field into an institution. The study documents the nuclear-safety institution as an integral part of the nuclear technostructure, which has historically used the specificity of its expertise as a buffer against outside interference

    The radioactivity inventories for emergency preparedness systems of nuclear power plants calculated by the combination of the generally-used in Japan (general-version), the INSS used by the present authors (INSS-version) and the newest nuclear data library and codes (newest-version) were compared, and the maintaining of conservativeness of the general-version and the INSS-version against the newest-version was examined. And the influences of the radioactivity inventories by the difference between the nuclear cross section and fission yield data, decay data and calculation codes were investigated. As a result, (1) the radioactivity inventories calculated by general-version and INSS-version were not confirmed the conservativeness to the newest-version. But the difference was less than 10%, and it would not give large influence to the calculation of the emergency preparedness system of nuclear plants. (2) The influence of the radioactivity inventories such as 135 Xe build-up were observed by the difference of neutron flux level in an operation of reactors that occurred by the variety of nuclear cross section and fission yield data. (3) Little influence by the variety of decay data was confirmed. (4) The ORIGEN2.1 code underestimated the amount of fission products generated by fission of minor actinides. From these result, the radioactivity inventories for the emergency preparedness system of nuclear power plants are recommended to use the calculation results by the combination of the library for ORIGEN2 based on JENDL3.3 and the ORIGEN2.2 code.

    Since the early 1990's, the OECD Nuclear Energy Agency (NEA) has offered its member countries a forum for improving efficiency and effectiveness in nuclear emergency management, with a particular focus on international aspects. A central approach to this has been the International Nuclear Emergency Exercise (INEXI series. Since 1993, the INEX series has proved successful in testing and advancing arrangements for nuclear emergency response. INEX 1, 2 and 2000, which focused on early-phase issues, provided a unique forum to test arrangements and concepts for international nuclear emergency management, particularly international communications, coordination and decision-making. Importantly, these exercises established a recognised international nuclear emergency exercise culture. The most recent exercise, INEX 3, was developed in response to international interest in longer term post-emergency issues. Conducted in 2005-2006, INEX 3 focused on later-phase consequence management issues following discovery of serious radio-logical contamination in the environment. The post-exercise evaluation identified several aspects of national consequence management which would benefit from international cooperation, and to which the international community could usefully contribute as part of planning and preparedness.

    In the nuclear emergency response activity in a East Japan great earthquake, the weakness the frame and the activity procedure (scheme) of the emergency response activity of our country that had been constructed after the accident of JCO became clear. Especially, it is necessary to recognize the importance of the enhancement of a prior plan after not only provision to response but also the damage to the environment occurs in the emergency for measures for restoration. Moreover, it is necessary to examine a concrete strategy about the management system strengthening of the radiation exposure at the accident. In this study, the experience and the finding in a East Japan great earthquake are arranged. The accident scenario that should be targeted is rearranged, and it proposes a new frame in the nuclear emergency response field through the requirement examinations such as the points of procedure, equipment, and the capital machine parts that lie a regulations frame of the nuclear emergency response, the activity frame of the nuclear emergency response, and materialized of the nuclear emergency response activity.

    Three nuclear reactors at Fukushima Daini Nuclear Power Station lost all their ultimate heat sinks owing to damage from the tsunami caused by the Great East Japan Earthquake on March 11, 2011. Water was injected into the reactors by alternate measures, damaged cooling systems were restored with promptly supplied substitute materials, and all the reactors were brought to a cold shutdown state within four days. Lessons learned from this experience were identified to improve emergency management, especially in the areas of strategic response planning, logistics, and functions supporting response activities continuing over a long period. It was found that continuous planning activities reflecting information from plant parameters and response action results were important, and that relevant functions in emergency response organizations should be integrated. Logistics were handled successfully but many difficulties were experienced. Therefore, their functions should be clearly established and improved by emergency response organizations. Supporting emergency responders in the aspects of their physical and mental conditions was important for sustaining continuous response. As a platform for improvement, the concept of the Incident Command System was applied for the first time to a nuclear emergency management system, with specific improvement ideas such as a phased approach in response planning and common operation pictures.

    Energy and reliable access to energy sources are essential to economic and social development and improved quality of life. However, limited access to modern energy still remains one of the major constraints to socio-economic development in many parts in the world. On the other hand, energy production, distribution and consumption may have many adverse effects on the local, regional and global environment including climate change. Production and consumption of fossil fuels constitutes the main source of greenhouse gas emissions (GHGs). Cleaner and affordable energy systems are therefore needed to address all of these effects and to contribute to environmental sustainability. Nuclear power is a proven technology with virtually no greenhouse gas emissions or emission of pollutants, and therefore is expected to play an increasing role in meeting this rapidly growing global requirements for clean and economic electricity. But, it is known that challenges and opportunities are polarities, and as opposite poles of the magnet, they do not exist separately. An opportunity for some can be a challenge for others, or a challenge today can become an opportunity tomorrow. The potential growth of nuclear power has increased, in some quarters, concern that nonproliferation should be given sufficient attention. In particular, since introduction of many new power reactors will require increased uranium enrichment services, with the potential proliferation risk of adding enrichment facilities in new countries. This has urged the international community to strongly support the development of safeguarded and well-regulated nuclear power around the world, with the aim to ensure that nuclear power is deployed through a commitment to the highest possible standards of nuclear safety, security, and non-proliferation. The keys issues and trends for nuclear power expansion include therefore problems related to (i) safety, security and reliability, (ii) public perception and acceptance, (iii

    This work introduces the Diagram of Emergency Exercise Coordination designed by the Nuclear Safety Team for better Emergency Exercise coordination. The Nuclear Safety Team was created with the mission of avoiding, preventing and mitigating the causes and effects of accidents at the IEA-R1. The facility where we conduct our work is located in an area of a huge population, what increases the responsibility of our mission: conducting exercises and training are part of our daily activities. During the Emergency Exercise, accidents ranked 0-4 on INES (International Nuclear Events Scale) are simulated and involve: Police Department, Fire Department, workers, people from the community, and others. In the last exercise held in June 2014, the scenario contemplated a terrorist organization action that infiltrated in a group of students who were visiting the IEA-R1, tried to steal fresh fuel element to fabricate a dirty bomb. Emergency procedures and plans, timeline and metrics of the actions were applied to the Emergency Exercise evaluation. The next exercise will be held in November, with the simulation of the piping of the primary cooling circuit rupture, causing the emptying of the pool and the lack of cooling of the fuel elements in the reactor core: this will be the scenario. The skills acquired and the systems improvement have been very important tools for the reactor operation safety and the Nuclear Safety Team is making technical efforts so that these Emergency Exercises may be applied to other nuclear and radiological facilities. Equally important for the process of improving nuclear safety is the emphasis placed on implementing quality improvements to the human factor in the nuclear safety area, a crucial element that is often not considered by those outside the nuclear sector. Surely, the Diagram of Emergency Exercise Coordination application will improve and facilitate the organization, coordination and evaluation tasks. (author)

  10. Concept for the Emergency Protection in the Vicinity of Nuclear Power Plants

    International Nuclear Information System (INIS)

    1998-03-01

    In 1991, the Swiss Federal Nuclear Safety Inspectorate (HSK) issued a concept of the regulations for the cloud phase 1 of an nuclear power plant accident in Switzerland valid at that time in co-operation with the Federal Commission for AC Protection (KOMAC) and the Swiss Federal Nuclear Safety Commission (KSA). This concept replaced the version of 1977, which then formed the basis for emergency preparedness in Switzerland. Legal changes, such as the civil protection legislation and the ordinance on the distribution of iodine tablets to the population, as well as experience gained from the emergency exercises necessitated a revision of the existing concept. The present concept is issued by the Federal Commission for AC Protection (KOMAC) and deals with all phases of an accident sequence in a Swiss nuclear power plant focussing on the pre- and cloud phase. It also gives an overview of responsibilities and alert procedures for accidents at foreign nuclear power plants and other nuclear installations, as well as of accidents in connection with transportation of radioactive materials. The concept is designed to help the federal and cantonal authorities in the vicinity of nuclear power plants in charge of emergency protection in preparing their emergency procedure specifications, and in the realisation of the readiness for emergencies. Furthermore, it shall serve the cantons as a guideline for the preparation of emergency specifications for the communities. The concept is based on the assumption that the executive bodies and emergency forces provided for the general civil protection are employed in case of an accident at a nuclear power plant.

    In Japan the new concepts for unclear emergency preparedness and response (EPR) have been developed based on issues addressed through experience of the emergency resulting from the Great East Japan Earthquake. Decision-making processes for implementing the protective actions have been shifted from forecasting basis to managing risk basis according with the time lines such as the intermediate response and late recovery phases. This study had been planned in fiscal 2010 prior to the emergency at Fukushima and criteria on the lifting of a nuclear emergency declaration and the measures after transition to recovery have been investigated. In this fiscal year, contents for protective actions, criteria for implementation of recovery actions, and concept of operation according with early, intermediate and late phases separately have been conducted.

    Because the goal of emergency preparedness for both chemical and nuclear hazards is to reduce human exposure to hazardous materials, this paper examines the interchange of lessons learned from emergency planning and accident experience in both industries. While the concerns are slightly different, sufficient similarity is found for each to draw implications from the others experience. Principally the chemical industry can learn from the dominant planning experience associated with nuclear power plants, while the nuclear industry can chiefly learn from the chemical industry's accident experience. 23 refs

    Two nuclear power stations on the coast of southern China are situated some 50 kilometers to the northeast of Hong Kong. Although the stations are far away from Hong Kong, the construction and operation of the nuclear power stations have generated public anxiety locally, in particular, after the Chernobyl accident in 1986. A comprehensive contingency plan which takes into account such concerns of the public has been implemented in Hong Kong. This plan not only aims to ensure a quick and timely response to mitigate the health impact of any accidental release but also targets to re-assure the public that the territory is not contaminated when appropriate. This paper describes the principal elements of the nuclear contingency plan in Hong Kong, namely, an extensive environmental radiation monitoring programme and a proactive public communication programme

    As part of the Emergency Preparedness Implementation Appraisal Program conducted by the Nuclear Regulatory Commission (NRC) with the technical assistance of the Pacific Northwest Laboratory (PNL), emergency preparedness exercises are observed on an annual basis at all licensed reactor facilities. One of the significant findings to arise from these observations was that a large number of the commonly observed problems originated in the design of the scenarios used as a basis for each exercise. In an effort to help eliminate some of these problems a scenario guidance handbook has been generated by PNL for the NRC to assist nuclear power plant licensees in developing scenarios for emergency preparedness exercises

    Emergency response mobile units play a significant role in the case of nuclear emergencies. The functioning and practice of such teams depend on the nature and phase of the nuclear emergency. In the acute phase, several teams with good navigational and communication abilities performing simple measurements can provide essential data for characterization of plume location and its magnitude. Therefore, such activities are complemental with the network of telemetric radiation monitors. However, in the late phase of an accident, in order to gather reliable data needed for utilization of remedial and recovery measures, a better equipped mobile units are necessary. (author)

    To give an overview of the legislative framework, which defined emergency planning in Croatia in the case of a nuclear accident, it's necessary to look at all international recommendations and obligations and the national legislation, acts and regulations. It has to be emphasized that Croatia signed three international conventions in this field, and by that took over some responsibilities and obligations. Beside that, it is also in Croatian interest to follow the recommendations of international institutions such as International Atomic Energy Agency (IAEA standards and technical documents). On the other hand, national legislation in this field consists of several laws, which cover nuclear safety measures, governmental organization, natural disasters and acts (decree, decisions) of responsible authority for emergency planning in the case of a nuclear accident (Ministry of Economy). This paper presents an overview of the international and Croatian legislation which influenced the emergency planning in the case of a nuclear accident. (author)

    Some background information of the severe accidents and source terms related to the nuclear power plant emergency planning are presented. The new source term information in NUREG-0956 and NUREG-1150, and possible changes in emergency planning requirements in U.S.A. are briefly provided. It is suggested that a principle is used in selecting source terms for establishing the emergency planning policy and a method is used in determining the Emergency Planning Zone (EPZ) size in China. Based on the research results of (1) EPZ size of PWR nuclear power plants being built in China, and (2) impact of reactor size and selected source terms on the EPZ size, it is concluded that the suggested principle and the method are suitable and feasible for PWR nuclear power plants in China

    One of the most important aspects of post-accident consequence management is the involvement of stakeholders: in the planning, preparation and execution as well as in sustaining efforts over the long term. Having recognised the significance of stakeholder participation in several International Nuclear Emergency Exercises (INEX), the NEA Committee on Radiation Protection and Public Health (CRPPH) decided to organise the Practices and Experience in Stakeholder Involvement for Post-nuclear Emergency Management Workshop to explore these issues. This summary highlights the key issues discussed during the workshop, which brought together 75 emergency management and communication specialists from 16 countries. In light of the accident at the Fukushima Daiichi nuclear power plant, the experience shared during this workshop will be central to further improving national emergency management arrangements

    The crisis situations for nuclear materials in nuclear facilities are provided for in the French regulation, as the decree of 12 May 1981 specifies that 'In any circumstance, the Ministry of Industry can order a physical inventory of the materials and its comparison with the accountancy records'. Such an inventory can be ordered in facilities holding category I nuclear materials, in case of a theft for example. The operators must be able to establish quickly if the stolen materials come from their facility. To test the organization set at the operators and competent authority levels respectively, five exercises of increasing complexity have already been carried out. These exercises have permitted the validation of procedures, composition of the various crisis centers, methodology for such an inventory and use of protected communication means. The authority crisis center includes members of the competent Authority and it's technical support body: staff members of the IPSN. It is in charge of the national managing of the operations, in relation with one or several site crisis centers. The site crisis center is the interface between the authorities and the facility crisis center. The operations of inventory are carried out from the roughest checking to the finest ones. To be efficient during the first hours of the crisis, the authority crisis center must have data bases at the disposal of its experts, containing information about physical protection and accountancy of the nuclear materials detained by the site and the relevant facilities.

    It is required by the Hungarian Atomic Energy Act and its enacting clause of 1980 that facilities established for the application of atomic energy be designed, constructed and operated in such a manner that abnormal operational occurrences can be avoided and unplanned exposures to radiation and radioactive substances can be prevented. The primary responsibility for planning and implementing emergency actions rests with the management of the operating organization. Thus one of the prerequisites of licensing the first nuclear power plant in Hungary was the preparation and submission for approval of an emergency plan by the operating organization. In addition to this, the council of the county where the power plant is located has also been obliged to prepare a complementary emergency plan, in co-operation with other regional and national authorities, for the prevention of consequences from an emergency that may extend beyond the site boundary of the plant. In preparing the complementary plan, the emergency plan of the facility had to be taken into account. Unlike most national authorities involved in nuclear matters, the Public Health Authority is involved in the preparation of plans for every kind of emergency in a nuclear facility, including even those whose consequences can probably be confined to the plant site. The paper discusses in detail the role and responsibility of the Public Health Authority in emergency planning and preparedness for nuclear facilities. (author)

    The aim of this publication is to serve as a practical tool for the preparation, conduct and evaluation of exercises to test preparedness for response to a nuclear or radiological emergency. It fulfils in part the functions assigned to the IAEA under Article 5.a(ii) of the Convention on Assistance in Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), namely, to collect and disseminate to States Parties and Member States information concerning the methodologies, techniques and available results of research on such emergencies. To ensure effective response to radiation emergencies when needed, provisions should be made for regular training of emergency response personnel. As stated in Preparedness and Response for a Nuclear or Radiological Emergency (Safety Requirements, Safety Standard Series No. GS-R-2), 'The operator and the response organizations shall make arrangements for the selection of personnel and training to ensure that the personnel have the requisite knowledge, skills, abilities, equipment, procedures and other arrangements to perform their assigned response functions'. A further requirement is that 'Exercise programmes shall be conducted to ensure that all specified functions required to be performed for emergency response and all organizational interfaces for facilities in threat category I, II or III and the national level programmes for threat category IV or V are tested at suitable intervals'. In 2004 the IAEA General Conference, in resolution GC(48)/RES/10 encouraged Member States to 'implement the Safety Requirements for Preparedness and Response to a Nuclear or Radiological Emergency'. This document is published as part of the IAEA Emergency Preparedness and Response Series to assist in meeting these requirements and to fulfil Article 5 of the Assistance Convention. It was developed based on a number of assumptions about national and local capabilities. Therefore, the exercise structure, terms and scenarios must be

  10. Planning and exercise experiences related to an off-site nuclear emergency in Canada: the federal component

    Eaton, R.S.

    1986-01-01

    The Canadian Government's Federal Nuclear Emergency Response Plan (off-site) (FNERP) was issued in 1984. In this plan, a nuclear emergency is defined as an emergency involving the release of radionuclides but does not include the use of nuclear weapons against North America. Because of the federal nature of Canada and its large area, special considerations are required for the plan to cover both the response to nuclear emergencies where the national government has primary responsibility and to provincial requests for assistance where the federal response becomes secondary to the provincial. The nuclear emergencies requiring the implementation of this plan are: (a) an accident in the nuclear energy cycle in Canada with off-site implications; (b) an accident in the nuclear energy cycle in another country which may affect Canada; (c) nuclear weapons testing with off-site implications which may affect Canada; and (d) nuclear-powered devices impacting on Canadian territory. Each emergency requires a separate sub-plan and usually requires different organizations to respond. Some scenarios are described. The Department of National Health and Welfare has established a Federal Nuclear Emergency Control Centre (FNECC). The FNECC participated in September 1985 in an exercise involving a nuclear reactor facility in the Province of Ontario and the experience gained from this activity is presented. The FNECC co-operates with its counterparts in the United States of America through a nuclear emergency information system and this network is also described. (author)

  12. Method for Developing a Communication Strategy and Plan for a Nuclear or Radiological Emergency. Emergency Preparedness and Response. Publication Date: July 2015

    International Nuclear Information System (INIS)

    2015-08-01

    The aim of this publication is to provide a practical resource for emergency planning in the area of public communication in the development of a radiation emergency communication plan (RECP). The term 'public communication' is defined as any activity that communicates information to the public and the media during a nuclear or radiological emergency. To avoid confusion, the term public communication has been used in this publication rather than public information, which may be used in other IAEA publications and documents to ensure consistency with the terminology used in describing the command and control system. This publication also aims to fulfil in part functions assigned to the IAEA in the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), as well as meeting requirements stated in IAEA Safety Standards Series No. GS-R-2, Preparedness and Response for a Nuclear or Radiological Emergency. Under Article 5(a)(11) of the Assistance Convention, one function of the IAEA is to collect and disseminate to States Parties and Member States information concerning methodologies, techniques and results of research with regard to the response to nuclear or radiological emergencies. This publication is intended to provide guidance to national and local authorities on developing an RECP which incorporates the specific functions, arrangements and capabilities that will be required for public communication during a nuclear or radiological emergency.

    The present study entitled ''Emergency Response and Nuclear Risk Governance: nuclear safety at nuclear power plant accidents'' deals with issues of the protection of the population and the environment against hazardous radiation (the hazards of nuclear energy) and the harmful effects of radioactivity during nuclear power plant accidents. The aim of this study is to contribute to both the identification and remediation of shortcomings and deficits in the management of severe nuclear accidents like those that occurred at Chernobyl in 1986 and at Fukushima in 2011 as well as to the improvement and harmonization of plans and measures taken on an international level in nuclear emergency management. This thesis is divided into a theoretical part and an empirical part. The theoretical part focuses on embedding the subject in a specifically global governance concept, which includes, as far as Nuclear Risk Governance is concerned, the global governance of nuclear risks. Due to their characteristic features the following governance concepts can be assigned to these risks: Nuclear Safety Governance is related to safety, Nuclear Security Governance to security and NonProliferation Governance to safeguards. The subject of investigation of the present study is as a special case of the Nuclear Safety Governance, the Nuclear Emergency governance, which refers to off-site emergency response. The global impact of nuclear accidents and the concepts of security, safety culture and residual risk are contemplated in this context. The findings (accident sequences, their consequences and implications) from the analyses of two reactor accidents prior to Fukushima (Three Mile Iceland in 1979, Chernobyl in 1986) are examined from a historical analytical perspective and the state of the Nuclear Emergency governance and international cooperation aimed at improving nuclear safety after Chernobyl is portrayed by discussing, among other topics, examples of &apos

    This paper mainly introduces the function and feature of emergency diesel generator in nuclear power plant, which plays an important role in nuclear accident. It minutely tells about the feature and configuration of relay protection and discusses the rationality of protection scheme, which shows that it can be completely contented all kinds of operation states. It is an analysis and argument about the principle of relay protection in detail, that would operate correctly when emergency diesel generator be in abnormal operating and serious fault conditions, such as cut off emergency diesel generator in order to avoid more harm to emergency diesel generator. It analyzes how the relay responses quickly and locks up the protection action under perturbations in the external power, so it can avoid unnecessary resection of emergency diesel generator to emergency power supply loss and effect of nuclear safety. It also analyzes the flexible use of protection setting of the protective relay to meet various operating status. It elaborates the particularity of relay protection which is due to the particularity of nuclear safety. It analyses the possibility of relay protection which has to be applied to other equipment and the protection setting that was provided by design institute, and puts forward the author's viewpoints.

    Highlights: ► PCTRAN is integrated with an atmospheric dispersion algorithm. ► The improved PCTRAN acts as an accident/incident simulator and a data exchange system. ► The software helps the responsible organizations decide the rescue and protective actions. ► The evaluation results show the nuclear power plant accident and its off-site dose consequences. ► The software can be used for nuclear power plant emergency responses. - Abstract: Protecting the public from radiation exposure is important if a nuclear power plant (NPP) accident occurs. Deciding appropriate protective actions in a timely and effective manner can be fulfilled by using an effective accident evaluation tool. In our earlier work, we have integrated PCTRAN (Personal Computer Transient Analyzer) with the off-site dose calculation model. In this study, we introduce PCTRAN as an evaluation tool for nuclear power plant emergency responses. If abnormal conditions in the plant are monitored or observed, the plant staffs can distinguish accident/incident initiation events. Thus, the responsible personnel can immediately operate PCTRAN and set up those accident/incident initiation events to simulate the nuclear power plant transient or accident in conjunction with off-site dose distributions. The evaluation results consequently help the responsible organizations decide the rescue and protective actions. In this study, we explain and demonstrate the capabilities of PCTRAN for nuclear emergency responses, through applying it to simulate the postulated nuclear power plant accident scenarios.

    Whit the objective of to complete the existent techniques for susceptibility evaluation to phenomenon of stress corrosion cracking in laboratories of Applied Sciences Area of National Institute of Nuclear Research; was realized and documented the modification of a high pressure and temperature equipment, identified as MEX-03 to carry out the implementation of a growth and crack propagation assay, using a constant load method. The assay was realized to a specimen of stainless steel AISI 304l type CT of an inch, which was previously thermally sensitize, simulating the typical degradation of this materials type below operation conditions in a BWR. The MEX-03 system, consist from an annexed auto key to a load system which originally was controlled by displacement; therefore were carried out modifications to achieve the control by load. The realized adjustments allowed to maintain a constant load during all the experiment, and as much the temperature conditions (T = 288 C) as of pressure (P = 8 Mpa) were controlled during the assay realization. The steel was exposed to a conditioned ambient with hydrogen gas addition; simulating a well-known alternative chemistry as hydrogen water chemistry that is used to mitigate the phenomenon of stress corrosion cracking, main degradation mechanism of austenitic stainless steels. The continuation of the crack behavior was realized by means of electric potential fall technique and later was validated of visual form through the fractographic analysis of cracked surface. The modification and control of equipment for realization of this experiment is necessary, for what should be carried out new assays, whose results will allow to establish the effect of dynamic and static methods in velocity determination of crack growth to laboratory level; to be considered in the existent models of crack propagation in systems and components in operation.

    Organizational incapability in developing unrealistic, impractical, inadequate and ambiguous mechanisms of radiological and nuclear emergency preparedness and response plan (EPR) causing emergency plan disorder and severe disasters. These situations resulting from 65.6% of poor definition and unidentified roles and duties of the disaster coordinator. Those unexpected conditions brought huge aftermath to the first responders, operators, workers, patients and community at large. Hence, in this report, we discuss prototyping and validating of Malaysia radiation and nuclear emergency preparedness and response plan simulation model (EPRM). A prototyping technique was required to formalize the simulation model requirements. Prototyping as systems requirements validation was carried on to endorse the correctness of the model itself against the stakeholder’s intensions in resolving those organizational incapability. We have made assumptions for the proposed emergency preparedness and response model (EPRM) through the simulation software. Those assumptions provided a twofold of expected mechanisms, planning and handling of the respective emergency plan as well as in bringing off the hazard involved. This model called RANEPF (Radiation and Nuclear Emergency Planning Framework) simulator demonstrated the training emergency response perquisites rather than the intervention principles alone. The demonstrations involved the determination of the casualties’ absorbed dose range screening and the coordination of the capacity planning of the expected trauma triage. Through user-centred design and sociotechnical approach, RANEPF simulator was strategized and simplified, though certainly it is equally complex.

    The reliability of the emergency ac-power systems typical of several nuclear power plants was estimated, the costs of several possible improvements was estimated. Fault trees were constructed based on a detailed design review of the emergency ac-power systems of 18 nuclear plants. The failure probabilities used in the fault trees were calculated from extensive historical data collected from Licensee Event Reports (LERs) and from operating experience information obtained from nuclear plant licensees. It was found that there are not one or two improvements that can be made at all plants to significantly increase the industry-average emergency ac-power-system reliability, but the improvements are varied and plant-specific. Estimates of the improvements in reliability and the associated cost are estimated using plant-specific designs and failure probabilities

    The measurement strategy applicable to Public Health in case of a Nuclear Emergency affecting the Netherlands is presented. Within the framework of the Dutch Nuclear Emergency Response System (NPK, abbreviated in Dutch) the National Poisons Control Centre of the RIVM/AZU has an advisory obligation towards the Ministry of Public Health, Welfare and Sports (WVS). This role comprises advice to relevant ministries, coordination of the measurement strategies and advice on persons to be reviewed, i.e. physical, biological and clinical dosimetry. The choice of dosimetric methods and measurements to be achieved in case of a larger scale nuclear emergency in the Netherlands is discussed. An actual plan of handling is presented for this measurement plan. Intervention levels defined in NPK 1991 serve as guidelines for successive actions to be performed by regional health services. 8 figs., 6 tabs., 81 refs

    This paper is an attempt to discuss a three-step-plan on medical emergency planning in case of severe accidents at nuclear power plants on the basis of own experiences in the regional area as well as on the basis of recommendations of the Federal Minister of the Interior. The medical considerations take account of the severity and extension of an accident whereby the current definitions used in nuclear engineering for accident situations are taken as basis. A comparison between obligatory and actual state is made on the possibilities of medical emergency planning, taking all capacities of staff, facilities, and equipment available in the Federal Republic of Germany into account. To assure a useful and quick utilization of the existing infra-structure as well as nation-wide uniform training of physicians and medical assistants in the field of medical emergency in case of a nuclear catastrophe, a federal law for health protection is regarded urgently necessary.

    The Swedish Radiation Safety Authority (SSM) is trusted with the task of implementing Sweden's bilateral assistance to Russia, Ukraine, Georgia, Belarus and Armenia in the fields of reactor safety, nuclear waste management, nuclear non-proliferation as well as radiation protection and emergency preparedness. In these fields, SSM also participates in various projects financed by the European Union. The purpose of this project-oriented report is to provide the Swedish Government and other funding agencies as well as other interested audiences in Sweden and abroad with an encompassing understanding of our work and in particular the work performed during 2008. the activities are divided into four subfields: Nuclear waste management; Reactor safety; Radiation safety and emergency preparedness; and, Nuclear non-proliferation. SSM implements projects in the field of spent nuclear fuel and radioactive waste management in Russia. The problems in this field also exist in other countries, yet the concentration of nuclear and radioactive materials are nowhere higher than in north-west Russia. And given the fact that most of these materials stem from the Cold War era and remain stored under conditions that vary from 'possibly acceptable' to 'wildly appalling' it is obvious that Sweden's first priority in the field of managing nuclear spent fuel and radioactive waste lies in this part of Russia. The prioritisation and selection of projects in reactor safety are established following thorough discussions with the partners in Russia and Ukraine. For specific guidance on safety and recommended safety improvements at RBMK and VVER reactors, SSM relies on analyses and handbooks established by the IAEA in the 1990s. In 2008, there were 16 projects in reactor safety. SSM implements a large number of projects in the field of radiation protection and emergency preparedness. The activities are at a first glance at some distance from the activities covered and foreseen by for instance the

    A reliability analysis is given for the emergency decay heat removal system of the Nuclear Ship ''Mutsu'' and the emergency sea water cooling system of the Nuclear Ship ''Savannah'', under ten typical nuclear ship accident conditions. Basic event probabilities under these accident conditions are estimated from literature survey. These systems of Mutsu and Savannah have almost the same reliability under the normal condition. The dispersive arrangement of a system is useful to prevent the reduction of the system reliability under the condition of an accident restricted in one room. As for the reliability of these two systems under various accident conditions, it is seen that the configuration and the environmental condition of a system are two main factors which determine the reliability of the system. Furthermore, it was found that, for the evaluation of the effectiveness of safety system of a nuclear ship, it is necessary to evaluate its reliability under various accident conditions. (author)

Knowing the foresee involvement of the public in a nuclear emergency, this preparation is carried out in the framework of contingency plans approved by the Nuclear Regulatory Authority. The population's preparation is a key task to arrive to the objective of minimizing the consequences of a nuclear incident. The ARN has defined the necessary countermeasures for the first hours and as the local population is involved, they must be trained in order to ensure the better level of efficacy. An important part in the preparation is the diffusion of information in the schools so the students know what they should do in case they receive an alert from the nuclear emergency command. The presentations at schools are divided by the differences in the levels of understanding, considering the ages of the students. These tasks are carried out once a year during the exercise preparation and it has a main objective: to diffuse the primordial protection actions. Similarly diffusion activities on protection actions were carried out with other sectors of the general public, with talk shows, discussions and explanation of doubts generated during the open meetings invited by the local civil defense, the nuclear power plant and the ARN. This work presents the details of tasks carried out with the educational community, the civil organizations the population and the conclusions obtained during these activities. (author)

    This document contains the Proceedings of the NEA/OECD Workshop held at Fontenay-aux-Roses on 12-14 June 1995. The Workshop discussions (20 contributions) were grouped in the following six sessions: 1.Introduction (3 papers); 2. Evaluation and management of agricultural questions (8 papers); 3. Economical and social aspects of the agricultural questions (1 paper); 4. Information exchange mechanisms (3 papers); 5. National strategies in agricultural emergency situations (4 papers); 6. Conclusions and recommendations (1 paper). Summarizing, conclusions were drawn to the following issues: public reaction to foodstuffs containing radioisotope concentrations under the danger standards, possible non-adherence of manufacturers, processors, distributors, et al, to the instructions and guidance from radiation protection specialists, integration of all the food chain factors in the elaboration of the emergency intervention programs, etc. As significant recommendations the following may be mentioned: 1. Differences between different intervention levels and the maximum admissible levels agreed upon by national, regional or international nutrition authorities should be further studied; 2. Problems created by the Chernobyl accident (as for instance, the methods of treatment of food chain products containing unacceptable radioactivity concentrations) are still present and must be solved; 3. Further studies should be done on the socio-cultural aspects of the communication, particularly on the information in rural environment; 4. The preventive measures in agriculture should be implemented as rapidly as possible; 5. In elaborating programmes of agriculture countermeasures, the management of contaminated media, particularly of forests and their effect on agriculture

    This paper examines the prospective role of computer-based decision aids for nuclear power plant emergency response. The role of these systems is subordinate to human activities, but in a complementary manner these systems process decision logic more accurately and foster a more thorough understanding of emergency situations than might other wise be possible. Within this context two decision support systems being developed are discussed. Both of these systems utilize technology derived from artificial intelligence, focussing on two different facets of emergency response. An automated emergency operating procedures (EOP) tracking expert system is described as a tactical aid for control room operator response. A reactor emergency action level monitor (REALM) expert system is proposed as a strategic decision aid for site emergency response. The discrimination between tactical and strategic decision-making is an intrinsic part of this examination

    The role of responding to emergencies at nuclear power plants is often considered the responsibility of the personnel onsite. This is true for most, if not all, of the incidents that may happen during the course of the plant's operating lifetime. There is however, the possibility of a major accident occurring at anytime. Major nuclear accidents at Chernobyl and Three Mile Island have taught their respective countries and communities a significant lesson in local emergency preparedness and response. Through these accidents, the rest of the world can also learn a great deal about planning, preparing and responding to the emergencies unique to nuclear power. This bibliography contains books, journal articles, conference papers and government reports on emergency response to nuclear power plant accidents. It does not contain citations for ''onsite'' response or planning, nor does it cover the areas of radiation releases from transportation accidents. The compiler has attempted to bring together a sampling of the world's collective written experience on dealing with nuclear reactor accidents on the sate, local and community levels. Since the accidents at Three Mile Island and Chernobyl, that written experience has grown enormously

    In a nuclear emergency, protective actions for the public should be taken in time. It is internationally proposed that Generic Intervention Levels (GILs) and generic action levels, determined based on cost-benefit analyses, be used as the decision criteria for protective actions. Operational Intervention Levels (OILs) are directly or easily measurable quantities corresponding to these generic levels. To assess the necessity of protective actions in a nuclear emergency, it is important that the environmental monitoring data required for applying and revising OILs should be promptly produced. It is discussed what and how to do for this task in the course of the emergency response. For an emergency environmental monitoring to be performed effectively, a through preparedness has to be made including maintenance of the organization and equipments, establishment of various procedure manuals, development of a supporting computer system and periodical training and exercises. It is pointed out that Korean legal provisions concerning GILs and OILs need to be amended or newly established

    Development of lithium ion batteries will play an important role in achieving innovative sustainable energy. To reduce the production cost of such batteries, the Indonesian government has instituted a strategy to use local resources. Therefore, this technology is now part of the National Industrial Strategic Plan. One of the most important scientific challenges is to improve performance of lithium batteries. Neutron scattering is a very important technique to investigate crystal structure of electrode materials. The unique properties of neutrons, which allow detection of light elements such as lithium ions, are indispensable. The utilization of neutron scattering facilities at the Indonesian National Nuclear Energy Agency will provide significant contributions to the development of improved lithium ion battery technologies.

    A risk assessment model of nuclear accident emergency protection countermeasure based on fuzzy matter-element analysis and Euclid approach degree is proposed in the paper. The weight of assessed index is determined by information entropy and the scoring by experts, which could not only make full use of the inherent information of the indexes adequately, but reduce subjective assumption in the course of assessment effectively. The applied result shows that it is reasonable that the model is adopted to make risk assessment for nuclear accident emergency protective countermeasure,and it could be a kind of effective analytical method and decision making basis to choose the optimum protection countermeasure.

    1994-01-01

    In our country, the medical emergency programs for the people living near nuclear power stations are well organized, however, preparation of medical staffs who are well trained is considered to be not sufficient. In the USA, on call 24 hours response to a radiological emergency is provided and funded by Department of Energy(DOE) or electric companies. Especially, REAC/TS is a part of DOE response network, in which there are provided well-trained physicians, nurses, health physicists, coordinators and support personnels. In United Kingdom, National Radiological Protection Board(NRPB) is responsible to a radiological emergency program. Each nuclear power station has its own emergency program consisting of a team of physicians, nurses and health physicists. In France, French Atomic Energy Commission (CEA) is a responsible agency for a radiological emergency program. On call 24 hours response to a radiological emergency is provided in Fontenay-aux Roses Institute and Curie Institute. Curie Institute also responds to radiological emergencies in other countries at the request of WHO. In Germany(West Germany), compulsory assurance system covers a radiological emergency program and a radiological protection. There are seven centers in West Germany, in which well-trained medical staffs are provided against radiological injuries. In this report, I tried to propose a new concept about emergency medical programs for nuclear power station accidents in Japan. I think it is a very urgent theme to provide on call 24 hours radiological emergency program, in which patients suffered from acute radiation sickness with internal contamination or contaminated radiation burns will be treated without any trouble. We have to make our best efforts to complete basic or clinical research about radiation injuries including bone marrow transplantation, radioprotectors, chelating agents and radiation burns etc. (J.P.N.)

    A radiological emergency preparedness for nuclear sites is recognized as an important measure against anticipated severe accidents with environmental releases of radioactive materials. While there are many individual means in the emergency preparedness for nuclear accidents, one of most important means is to make a decision of evacuation or shelter of the public residents with the emergency plan zone (EPZ) of a nuclear site. In order to prepare an effective strategy for the evacuation as a basis of the emergency preparedness, it may need the understanding of atmospheric dispersion characteristics of radiation releases to the environment, mainly depending upon the weather conditions of a radiation releases location, i.e., a nuclear site. As a preliminary study for the development of an effective emergency plan, the basic features of the weather conditions of a specific site were investigated. A main interest of this study is to identify whether or not the site weather conditions have specific features helpful for a decision making of evacuation of the public residents

    EVATECH, Information Requirements and Countermeasure Evaluation Techniques in Nuclear Emergency Management, was a research project in the key action 'Nuclear Fission' of the fifth EURATOM Framework Programme (FP5). The overall objective of the project was to enhance the quality and coherence of response to nuclear emergencies in Europe by improving the decision support methods, models and processes in ways that take into account the expectations and concern of the many different parties involved - stake holders both in managing the emergency response and those who are affected by the consequences of nuclear emergencies. The project had ten partners from seven European countries. The development of the real-time online decision support system RODOS has been one of the major items in the area of radiation protection within the European Commission's Framework Programmes. The main objectives of the RODOS project have been to develop a comprehensive and integrated decision support system that is generally applicable across Europe and to provide a common framework for incorporating the best features of existing decision support systems and future developments. Furthermore the objective has been to provide greater transparency in the decision process to: improve public understanding and acceptance of off-site emergency measures, to facilitate improved communication between countries of monitoring data, predictions of consequences, etc., in the event of any future accident, and to promote, through the development and use of the system, a more coherent, consistent and harmonised response to any future accident that may affect Europe.

    The Geographic Information System (GIS) implementation for the preparation and response in case of to radiological and nuclear emergencies is being developed in the Emergency Control Center of the Argentina Nuclear Regulatory Authority, since many years ago. Additionals features have been incorporated such as integration with the results of radiological monitoring, improving and expanding its benefits both in the preparation stage and during the work of emergency response. This paper shows the specific application of GIS to radiological monitoring in case of emergency situations such as during the search of orphan sources and the characterization of geographic context around nuclear power plants and atomic centers. The GIS provides essential data cartographic for the monitoring with sophisticated detectors, to integrate with the information received with infrastructure, urban and rural population maps, physical features of the place, satellite images, etc. The monitoring results are analyzed and compared with relevant information for decision making during the response, like evacuation routes, affected population, security forces in the area, radiological characterization, application of protective actions, hospitals, schools, etc. These two integrated tools improve preparedness and response system in case of radiological or nuclear emergency.

    The purposes of the study are: to implement obligations specified in treaties and domestic laws and to enhance the nuclear transparency suffered from a careless experiment, being issued in 2004, with nuclear material; and to prepare nuclear emergency and to settle down effectively the emergency situation. We established an infrastructure of the system of accounting for and control of nuclear material. and installed systematic measures to deal the cases of radiation accidents. In the first year (2006) the project is focused on the development of two systems: an information treatment system that controls and manages the nuclear material in facilities at KAERI; and a real-time surveillance system that integrates the safety system information of nuclear facilities in KAERI. The development of information treatment system for IAEA safeguards and facility-level accountancy has been initiated in October, 2006, and planned to complete by October 2007. Communication channels between the emergency control head-quarter and the briefing rooms of facilities and accident areas are established to implement an advanced supervision system for radiation accidents. Also, a surveillance system, that collects and supervises the facilities' safety system parameters in real time, is installed and confirmed that the display system of the safety parameters is stably operating.

    The exploitation and use of nuclear energy are of great importance to developing of national economy and maintaining state security. But it also has a possibility of serious accident. Based on the principles of airborne gamma ray spectrometry in the uranium exploration, nuclear emergency monitoring has been developed. This method has high sensitivity to the radioactive nuclides in the air and on the ground, and with the advantage of fast measuring in large area. Hence, in the middle of 1980s, some developed countries began to survey the scope and degree of nuclear accident contamination and environmental radiation level monitoring in the surrounding nuclear facilities, it can also be used to search for the lost radioactive sources. According to the actual situation and compatible guideline, National Nuclear Emergency Office consigned this project to our Center. After development and study on the Airborne gamma ray spectrometer system associated NaI(Tl) used for the uranium exploration, a compatible spectrometer system associated NaI(Tl) was established in a short period by us, which can fulfill airborne nuclear emergency survey basically. In normal situation, it was proved that the start-up time is less than two hours including transport to the airport. The system has high sensitivity to radioactive plume of 41 Ar and can respond rapidly to artificial sources, such as 192 Ir, 60 Co, 137 Cs and 131 I etc

In this regards, this study establishes, operates and upgrades the nuclear control and management information system of the KAERI that assumed the prerequisite means for Integrated Safeguards systems of the IAEA which is implemented from the July of 2008. It is also included the radiological emergency system that contains the safety information surveillance system in KAERI to meet the national legislative requirements. The nuclear control and management information system of the KAERI could be controlled and managed the accounting information of the nuclear facility with on-line manner. This system enhances transparency of accounting management of the KAERI in terms of effective ways for the Agency inspectors and national inspectors to implement the no-notice inspection under the Integrated Safeguards system. To complete the nuclear safety information collecting and monitoring system at EOF for KAERI, the real-time remote monitoring systems for RIPF, IMEF, PIEF were established. In addition, after the review of the abnormal condition of RMS data, the notification system for a radiation abnormal condition at nuclear facilities was operated. And also, the server of emergency management system was improved, the emergency situation notification system to all KAERI and KNF site was established

    2004-01-01

    Training of the non-technical (social and cognitive) skills that are crucial to safe and effective management by teams in emergency situations is an issue that is receiving increasing emphasis in many organisations, particularly in the nuclear power industry. As teams play a major role in emergency response organisations (ERO), effective functioning and interactions within, between and across teams is crucial, particularly as the management of an emergency situation often requires that teams are extended by members from various other sections and strategic groups throughout the company, as well as members of external agencies. A series of interviews was recently conducted with members of a UK nuclear emergency response organisation to identify the non-technical skills required by team members that would be required for managing an emergency. Critical skills have been identified as decision making and situation assessment, as well as communication, teamwork, and stress management. A number of training strategies are discussed which can be tailored to the roles and responsibilities of the team members and the team leader, based on the roles within the team being defined as either Decision Maker, Evaluator, or Implementor, according to Nuclear Energy Institute (NEI) classifications. It is anticipated that enhanced learning of the necessary non-technical skills, through experience and directed practice, will improve the skills of members of emergency response teams

    Training of the non-technical (social and cognitive) skills that are crucial to safe and effective management by teams in emergency situations is an issue that is receiving increasing emphasis in many organisations, particularly in the nuclear power industry. As teams play a major role in emergency response organisations (ERO), effective functioning and interactions within, between and across teams is crucial, particularly as the management of an emergency situation often requires that teams are extended by members from various other sections and strategic groups throughout the company, as well as members of external agencies. A series of interviews was recently conducted with members of a UK nuclear emergency response organisation to identify the non-technical skills required by team members that would be required for managing an emergency. Critical skills have been identified as decision making and situation assessment, as well as communication, teamwork, and stress management.

    2014-01-01

    In almost all nuclear and radiological emergencies, local emergency services (e.g. local medical, law enforcement, and fire brigades) will have the most important role in the early response. Within hours, hospitals may also have an important role to play in the response at the local level. Since nuclear and radiological emergencies are rare, medical responders often have little or no experience in dealing with this type of emergency and inexperience may lead to an inadequate response. For this reason, training in medical preparedness and response for a nuclear or radiological emergency is an important aspect of preparedness and response activities. These materials are designed for use at a training course on medical preparedness and response for a nuclear or radiological emergency. They contain a wide range of lectures and supporting materials, which cover the basic topics and more specific areas of medical preparedness and response. Therefore, in planning their specific courses, organizers are encouraged to choose those lectures and supportive materials from the CD-ROM that best match their training priorities. Materials on the CD-ROM address the following areas: • Terrorism in Perspective; • Malicious Act Scenarios; • Providing Information to the Medical Community and the Public; • Medical Response to a Radiation Mass Casualty Event; • Handling of Contaminated Persons in Malicious Events; • Planning and Preparedness for Medical Response to Malicious Events with Radioactive Material; • Handling the Bodies of Decedents Contaminated with Radioactive Material; • Radiation Emergencies: Scope of the Problem; • Common Sources of Radiation; • Basic Concepts of Ionizing Radiation; • Basic Concepts of Radiation Protection; • Biological Effects of Ionizing Radiation – Basic Notions; • Basics of Radiopathology; • External Radioactive Contamination; • Internal Radioactive Contamination; • Acute Radiation Syndrome; • Cutaneous Radiation

    An emergency plan was prepared for minimizing the consequences of any unforeseen radiation accident in Cekmece Nuclear Research and Training Centre (CNAEM) in Istanbul, Turkey. CNAEM is situated near Kucukcekmece Lake, which is about 30 km to the west of Istanbul. It includes two pool-type research reactors of 1 MW(th) and 5 MW(th). The population in the nearest inhabited areas varies from 1000 to 50,000. Accidents are classified, according to their severity, into three categories at CNAEM: (a) local emergency, (b) on-site emergency, (c) off-site emergency. During local emergency situations evacuation is not necessary. An on-site emergency situation requires the evacuation of personnel from the plant. Personnel hearing the emergency alarm should move directly to the preselected place as soon as possible. An off-site emergency is any accident that leads to widespread contamination outside the boundary. In this situation the Turkish Atomic Energy Authority and governmental authorities are notified immediately. The emergency organization group consists of: (a) Plant Superintendent, (b) Emergency Director, (c) Reactor Supervisor, (d) Senior Health Physicist, (e) Reactor Shift Operator, (f) Health Physicists. The administration building will be used as the Emergency Control Centre. The emergency teams working under the direction of the Emergency Director consist of: (a) Health Physics, (b) Fire and Rescue, (c) First Aid and Decontamination, (d) Transportation, (e) Security and Patrol. The emergency situation is evaluated in three phases at CNAEM. The first phase is the first few hours after the beginning of the accident. The second phase is between 8-10 hours or more following the first phase. The third phase is the recovery phase. The integrated doses over periods of two hours and two days are calculated according to the situation of the core, i.e. total or partial melting, and weather conditions. The results of the calculated parameters can be adapted to possible

    As recommended by International Atomic Energy Agency (IAEA), preparedness for response to nuclear/radiological emergencies is essential for all nations including those not having nuclear facilities. Methodology and systems for quick assessment of radiological impact following any large scale radioactive release/contamination in the environment are already developed. Efforts are being made to provide Geographical Information System (GIS) support for enhancing the capability of quick decision making on the implementation of countermeasures and to strengthen the Emergency Preparedness Program. This requires development of the database of nuclear facilities, roads, buildings, agriculture land, population density and geolocating using geocoded addresses. GIS helps in the creation of custom maps that spatially show several data layers pertinent to the cities/area around the nuclear power plants. The GIS based software imports and spatially displays the predicted movement of radioactive plume and helps in the revision of emergency plans based on the periodic inputs from various systems and monitoring teams. These tools, allow the Emergency Response Centers to take decisions regarding the progress, success and future direction of response in large cities/complex sites. (author)

    An accident in a nuclear facility causes a great social cost. To prevent an unexpected nuclear accident from spreading to the catastrophic disaster, emergency response action in early stage is required. However, high radiation environment has been proved as a challenging obstacle for human workers to access to the accident site and take an action in previous accident cases. Therefore, emergency response robotic technology to be used in a nuclear accident site instead of human workers are actively conducted in domestically and internationally. Robots in an accident situation are required to carry out a variety of tasks depend on the types and patterns of accidents. An emergency response usually includes removing of debris, make an access road to a certain place and handling valves. These tasks normally involve high payload handling. A small sized high power robotic manipulator can be an appropriate candidate to deal with a wide spectrum of tasks in an emergency situation. In this paper, we discuss about the design of a high power robotic manipulator, which is capable of handling high payloads for an initial response action to the nuclear facility accident. In this paper, we presented a small sized high power robotic manipulator design. Actuator types of manipulator was selected and mechanical structure was discussed. In the future, the servo valve and hydraulic pump systems will be determined. Furthermore, control algorithms and test bed experiments will be also conducted

    GAL(generic action level)s were derived using cost-benefit methods. But the factors used to derive GALs, such as Gross National Product (GNP) and cost of foodstuff, have been changed for last 10 years. Moreover the standards did not consider exposure situation change from emergency exposure to existing exposure situation. In this study, two ways to revise existing standards for foodstuff control were considered; 1st, revision of GAL, 2nd, newly derived reference level. In this study, two methods to revise food control criteria following nuclear emergency were suggested. GAL based on recent GNI and cost of foodstuff would be revised and decreased up to 30 % than existing criteria. DRLs reflecting exposure situation and consumption pattern were smaller than existing criteria for group 1 nuclides. The approach considered in the study would be applied to set up domestic criteria for food control during and following nuclear or radiological emergency.

    A PC-oriented Emergency Response System in case of nuclear accident (BERS) is developed and works operationally in the National Institute of Meteorology and Hydrology (NIMH). The creation and development of BERS was highly stimulated by the ETEX (European Tracer Experiment) project. BERS comprises two main parts - the operational and the accidental ones. The operational part, run automatically every 12 hours, prepares the input meteorological file used by both trajectory and dispersion models, runs the trajectory models, visualizes the results and uploads the maps of trajectories to a dedicated web-site. The accidental part is activated manually when a real radioactive releases occur or during emergency exercises. Its core is the Bulgarian dispersion models EMAP. Outputs are concentration, accumulated deposition and selected doses fields. In the paper, the BERS overall structure is described and examples of its products are presented. Key words: nuclear accident, emergency response, early warning system, air dispersion models, radioactive exposure dose. (Author)

    In October 1982, the Yugoslavian Government requested the Agency's assistance in observing and evaluating an emergency preparedness exercise (code named ''POSAVJE 82'') on 5 and 6 November 1982, to test emergency plans and arrangements supportive of the KRSKO Nuclear Power Plant. The Krsko Nuclear Power Plant is a single unit pressurized water reactor of United States (Westinghouse) design rated at 664 MWe (Gross) and is located at Krsko, Socialist Republic of Slovenia, Yugoslavia. This assistance was provided by sending a Special Assistance Mission team of experts under the general provisions of the Agency's circular letter SC/651-3 of 7 April 1981 to Member States which offered such assistance upon request. This mission was a follow-up to a previous mission requested by the Yugoslavian Government which was conducted 24 June - 1 July 1981. At that time, the mission consisted of examining the then existing arrangements for emergency planning in support of the KRSKO Nuclear Power Plant at the National, Republic, local and nuclear power plant levels and discussing with Yugoslavian authorities criteria for emergency plan development and improvement. As a result of this 1981 mission, a ''Report to the Goverment of Yugoslavia'' (IAEA TA Report 1827 of 17 September 1981) was transmitted to the Yugoslavian Government. This report set forth a number of recommendations for improving and further developing the various emergency plans and arrangements for the KRSKO Nuclear Power Plant. A summary of the major recommendations contained in the report is given in Section 2.2. The entire report is listed as Reference 1 of Annex A

    Since the beginning of the 1990's, the OECD Nuclear Energy Agency (NEA) has offered its member countries a forum for improving efficiency and effectiveness in nuclear emergency management, focusing in particular on the international aspects of emergency preparedness and response. A central approach to this has been the preparation and conduct of the International Nuclear Emergency Exercise (INEX) series. The INEX 3 consequence management exercises were developed by the NEA Working Party on Nuclear Emergency Matters in response to its members desire to better prepare for the longer-term response following a nuclear or radiological emergency. The INEX 3 exercise series was developed in 2002-2004, and conducted throughout 2005 and early 2006 by 15 participating countries. The INEX 3 evaluation workshop held in Paris (France) in May 2006 was convened with the objective of allowing participants to share their national experiences with INEX 3, compare approaches, analyse the implications on decision making and identify key needs in longer-term consequence management. In addition to providing a valuable discussion forum for participants, the workshop concluded by establishing a set of identified needs in longer-term consequence management to which the participants felt that the NEA and international community could usefully contribute. These included the four main areas addressed by the exercise agriculture and food countermeasures, decisions on countermeasures such as travel, trade or tourism, recovery management and public information as well as stakeholder involvement and liability/compensation issues. This report summarises the development of the INEX 3 exercise, the major evaluation outcomes of the national exercises, and the key policy-level outcomes, recommendations and follow-up activities arising from the exercise and workshop.

    Nuclear licensees are required to maintain a prediction system during normal condition for using a nuclear emergency by the Basic Plan for Disaster Prevention of government. With prediction of the incident progress, if the present condition of nuclear power plant is understood appropriately and it grows more serious with keeping the present situation, it is in predicting what kind of situation will be occurred in the near future, choosing the effective countermeasures against the coming threat, and understanding the time available of intervention time. Following the accident on September 30 1999 in the nuclear fuel fabrication facility in Tokai Village of Ibaraki Prefecture, the Institute of Nuclear Safety System started development of incident progress prediction technologies for nuclear emergency preparedness. We have performed technical applications and made improvements in nuclear emergency exercises and verified the developed systems using the observed values of the Fukushima Daiichi Nuclear Power Plant accident. As a result, our developed Incident Progress Prediction System was applied to nuclear emergency exercises and we accumulated knowledge and experience by which we improved the system to make predictions more rapidly and more precisely, including for example, the development of a prediction method for leak size of reactor coolant. On the other hand, if a rapidly progressing incident occurs, since end users need simple and quick predictions about the public's protection and evacuation areas, we developed the Radioactive Materials Release, Radiation Dose and Radiological Protection Area Prediction System which changed solving an inverse problem into a forward problem solution. In view of the water-level-decline incident of the spent fuel storage facility at the Fukushima Daiichi Nuclear Power Plant, the spent fuel storage facility water level and the water temperature evaluation tool were improved. Such incident progress prediction technologies were

    In 2009, the Michigan Department of Community Health (MDCH) made potassium iodide (KI), a nonprescription radio-protective drug, available by mailing vouchers redeemable at local pharmacies for KI tablets, at no cost to residents living within 10 miles of Michigan's 3 nuclear power plants (NPPs). MDCH conducted an evaluation of this program to determine Michigan's KI coverage and to assess general emergency preparedness among residents living near the NPPs. KI coverage was estimated based on redeemed voucher counts and the 2010 Census. Telephone surveys were administered to a random sample (N = 153) of residents living near Michigan's NPPs to evaluate general emergency preparedness, reasons for voucher use or nonuse, and KI knowledge. Only 5.3% of eligible residences redeemed KI vouchers. Most surveyed residents (76.5%) were aware of living near an NPP, yet 42.5% reported doing "nothing" to plan for an emergency. Almost half of surveyed voucher users did not know when to take KI or which body part KI protects. Among voucher nonusers, 48.0% were either unaware of the program or did not remember receiving a voucher. Additional efforts are needed to ensure that all residents are aware of the availability of KI and that recipients of the drug understand when and why it should be taken. Minimal emergency planning among residents living near Michigan's NPPs emphasizes the need for increased emergency preparedness and awareness. Findings are particularly salient given the March 2011 Fukushima Daiichi Nuclear Power Plant emergency in Japan.

    The 5 km sterilized zone (SZ) and 16 km emergency planning zone (EPZ) were set up for Indian nuclear power plants in 1960s. There is also a requirement that the growth of population in SZ shall be controlled. In the current scenario where population growth in SZ at some of the sites is much above the natural growth, the distinction between the two zones may disappear. It is clear that emergency preparedness plans shall be in place for these zones. In today's context if these numbers have to be revised, there is a need to give a fresh look to the basis and growth of population in these zones. In view of this, the issue of size and requirement of SZ and EPZ in Indian context are revisited. Technological advances and emerging improvements in some of the elements of emergency response were reviewed to determine their potential effects on decisions of emergency protective actions. Some such elements which affect implementation of emergency countermeasures effectively in SZ and EPZ around Indian nuclear power plants are discussed in this paper. (author)

    A nuclear incident is defined as a series of events leading to release of radioactive materials into the environment of sufficient concentration to make necessary protective actions. The decision to initiate a protective action is a complex process. The benefits of taking the action is weighed against the involved risk and constraints. In addition the decision will be made under difficult emergency conditions, probably with little detailed information available. Therefore, considerable planing is necessary to reduce to manageable levels the types of decisions leading to effective responses to protect the public in the event of a nuclear incident. The sequence of events for developing emergency plans and responding to nuclear incidents will vary according to individual circumstances, because the international recommendations and site-specific emergency plans cannot provide detailed guidance for all accident scenarios and variations in local conditions. Flexibility must be maintained in emergency response to reflect the actual circumstances encountered (e.g. source term characteristics, the large number of possible weather conditions and environmental situation such as time of the day, season of the year, land use and soil types, population distribution and economic structures, uncertainties in the availability of technical and administrative support and the behaviour of the population). This further complicates the decision-making process, especially under accident conditions where there are time pressures and psychological stress. Therefore one the most important problems in the case of a nuclear emergency is quantifying all these very different types of off-site consequences. Last years, and in particular since the Chernobyl accident, there has been a considerable increase in the resources allocated to development of computerised systems which allow for predicting the radiological impact of accidents and to provide information in a manageable and effective form to

    The Department of Energy (DOE) has formed a Nuclear Facilities Personnel Qualification and Training (NFPQT) Committee to assess the implications of the recommendations contained in the President's Commission Report on the Three Mile Island (TMI) Accident (the Kemeny Commission report) that are applicable to DOE's nuclear reactor operations. Thirteen DOE nuclear reactors have been reviewed. The assessments of the 13 facilities are based on information provided by the individual operator organizations and/or cognizant DOE Field Offices. Additional clarifying information was supplied in some, but not all, instances. This report indicates how these 13 reactor facilities measure up in light of the Kemeny and other TMI-related studies and recommendations, particularly those that have resulted in upgraded Nuclear Regulatory Commission (NRC) requirements in the area of emergency planning and response

    1984-07-01

    More than 1500 people have been interviewed on their attitudes towards and their knowledge of emergency actions on nuclear accidents at nuclear power plants. Of the people addressed, 768 lived in the inner zones close to the power plants. 775 were farmers near the four nuclear power sites in Sweden. The farmers lived both in inner zones and zones further away. A majority consider themselves not well-informed on health risks after a nuclear accident. More than a third would want more information on what to do in case of accident. Farmers outside the inner zones are more dissatisfied with the information status than other groups. Farmers from the inner zones consider the information given inadequate regarding risks to their health and also health risks for their live stock. The results of interviews are in some cases compared with the information given to the public. (Aa)

    There are emerging trends in the nuclear fuel cycle that have implications for waste management. This paper will discuss activities in both the front-end and back-end of the nuclear fuel cycle for the U.S. Nuclear Regulatory Commission (NRC)-regulated entities. Particular focus will be given to the front-end which includes uranium recovery facilities, conversion facilities, and enrichment facilities. The back-end activities include progress on the proposed high-level waste geologic repository at Yucca Mountain, NV and efforts to reprocess spent nuclear fuel or down-blend HEU. While there are potential environmental impacts due to construction and dismantling of fuel cycle facilities, this paper focuses on the operational waste stream that will need to be managed as a result of fuel-cycle facilities.

    Consequent to the terrorist attacks on WTC in USA and other similar terrorist attacks worldwide, there has been increasing public concern regarding the use of radioactive materials in a malevolent act. As the radioactive sources are widely used in the industries, terrorists may have access to these facilities and obtain the radioactive material suitable for making Radioactive Dispersal Device (RDD) often called as dirty bomb. Response to nuclear or radiological emergency may involve highly specialized agencies or technical experts. Hence well-coordinated arrangements must be integrated with those required for any other conventional emergencies. During radiological emergencies, emergency service personnel are expected to play a major role in the early response. Though these personnel are well equipped and trained in tackling the normal emergencies it is essential to train them to deal with the radiological emergencies due to inherent characteristics of radioactivity. For the effective management of radiological emergencies, these first responders are required to be trained in such a way that they understand the concept of radiation protection. This objective can be achieved by using a typical training module consisting of interactive class room lectures, practical sessions to use the instruments and handling of radioactive sources, demonstration of radiation protection practices, exhibition of all radiation survey instruments and protective equipment etc., display of various posters and RDD Emergency Exercise.

    This study aims to develop a taxonomy of coordination behaviours during emergencies in nuclear power plants (NPPs). We summarised basic coordination behaviours from literature in aviation, health care and nuclear field and identified coordination behaviours specific to the nuclear domain by interviewing and surveying control crew operators. The established taxonomy includes 7 workflow stages and 24 basic coordination behaviours. To evaluate the reliability and feasibility of the taxonomy, we analysed 12 videos of operators' training sessions by coding coordination behaviours with the taxonomy and the inter-rater reliability was acceptable. Further analysis of the frequency, the duration and the direction of the coordination behaviours revealed four coordination problems. This taxonomy provides a foundation of systematic observation of coordination behaviours among NPP crews, advances researchers' understanding of the coordination mechanism during emergencies in NPPs and facilitate the possibility to deepen the understanding of the relationships between coordination behaviours and team performance. Practitioner Summary: A taxonomy of coordination behaviours during emergencies in nuclear power plants was developed. Reliability and feasibility of the taxonomy was verified through the analysis of 12 training sessions. The taxonomy can serve as an observation system for analysis of coordination behaviours and help to identify coordination problems of control crews.

    1984-01-01

    The U.S. Nuclear Regulatory Commission requires that nuclear power plants provide for rapid assessment and response in the event of a radiological emergency. At the Diablo Canyon Nuclear Power Plant, Pacific Gas and Electric Company uses a system of linked central minicomputer, satellite desktop computers and microprocessors to provide decision makers with timely and pertinent information in emergency situations. The system provides for data acquisition and microprocessing at meteorological and radiological monitoring sites. Current estimates or projections of offsite dose commitment are made in real-time by a dispersion/dose calculation model. Computerized dissemination of data and calculational results to decision makers at the government and utility levels is also available. The basic system in use is a commercially available Emergency Assessment and Response System (EARS). This generic system has been modified in-house to meet requirements specific to emergency situations at the plant. Distinctive features of the modification program includes: a highly professional man-machine interaction; consideration of site-specific factors; simulation of environmental radiology for development of drill scenarios; and concise, pertinent reports as input to decision making

    In India, DAE being the nodal agency for technical support for response to any radiation emergency nuclear disaster and various nuclear and radiological emergency scenarios and their impacts are identified. To reduce their consequences development of methodologies for detection and quick impact assessment, trained First Responders and Quick Response Teams (QRTs), twenty two DAE Emergency Response Centers, mobile and aerial radiation monitoring systems, aerial and ground based validation trials etc. are carried out. Study related to radiological threats and simulated RDD experiments conducted using stable isotopes indicates that radiation levels for distances more than 50 m will not be very high as hotspots may be restricted to nearby area. The biggest challenge from an RDD explosion will be handling of the radioactive contamination and 'fear factor' compared to radiation exposure to public or First Responders. Level and pattern of radioactive contamination on ground following releases during nuclear accidents and minimum strength of orphan radioactive sources to be detected are taken into account for optimizing systems and monitoring methodology required for emergency preparedness

    In 1986 the Chernobyl accident led the Dutch Government to a reconsideration of their possibilities for managing nuclear emergencies. It was decided to improve both the national emergency management organization and the infrastructure for collecting and presenting technical information. The first improvement resulted in the National Plan for Nuclear Emergency Planning and Response (EPR) and the second in a series of technical facilities for the assessment of radiation doses. Since 1990, following the implementation of the EPR and most of the technical facilities, several emergency exercises have taken place to test the effectiveness of organization and infrastructure. Special emphasis has been given to the early phase of the simulated accidents. This paper summarises the experiences obtained from these exercises. Major obstacles appear to be: (1) keeping all participants properly informed during the process, (2) the difference in working attitude of technical experts and decision-makers, (3) premature orders for countermeasures and (4) the (too) large number of people involved in the decision-making process. From these experiences requirements for instruments can be deduced. Such instruments include predictive models, to be used for dose assessment in the early phase of an accident which, apart from being fast, should yield uncomplicated results suitable for decision-makers. Refinements of models, such as taking into account the specific nature of the (urban) environment, are not needed until the recovery phase of a nuclear accident. (author)

    1990-01-01

    Much progress has been made over the last decade in the field of emergency planning and preparedness, including the development of guidance, criteria, training programmes, regulations and comprehensive plans in the support of nuclear facilities. To provide a forum for international review and discussion of actual experiences gained and lessons learned from the different aspects of recovery techniques and operations in response to serious accidents at nuclear facilities and accidents associated with radioactive materials, the IAEA organized the International Symposium on Recovery Operations in the Event of a Nuclear Accident or Radiological Emergency. The symposium was held from 6 to 10 November 1989 in Vienna, Austria, and was attended by over 250 experts from 35 Member State and 7 international organizations. Although the prime focus was on on-site and off-site recovery from nuclear reactor accidents and on recovery from radiological accidents unrelated to nuclear power plants, development of emergency planning and preparedness resources was covered as well. From the experiences reported, lessons learned were identified. While further work remains to be done to improve concepts, plans, materials, communications and mechanisms to assemble quickly all the special resources needed in the event of an accident, there was general agreement that worldwide preparations to handle any possible future radiological emergencies had vastly improved. A special feature of the symposium programme was the inclusion of a full session on an accident involving a chemical explosion in a high level waste tank a a plutonium extraction plant in the Southern Urals in the USSR in 1957. Information was presented on the radioactive release, its dissemination and deposition, the resultant radiation situation, dose estimates, health effects follow-up, and the rehabilitation of contaminated land. This volume contains the full text of the 49 papers presented at the symposium together with a

    The effect of changes of intervention levels and meteorological conditions on the early emergency countermeasures is analysed for nuclear power plant emergencies. A Lagrangian puff model RIMPUFF is used to predict dose distributions under stable and unstable meteorological conditions. The release scenario for PWR6 is used as an example to determine emergency areas for different intervention levels. The prediction results show that the evacuation area radius is 5 km and the radii for sheltering and intake-of stable iodine are both 10 km. The difference between the emergency areas determined by the intervention levels given in HAF0703/NEPA9002 and IAEA safety series No. 109 is only in the sheltering area which is much smaller using the IAEA guidelines

    The importance of training of safety personnel to deal with real world scenarios is prevalent amongst nuclear emergency preparedness and response organizations. For the development of training tools we have committed to ensure that field procedures, data collection software and decision making tools be identical during training sessions as they would be during a real emergency. By identifying the importance of a fully integrated tool, we have developed a safety support system capable of both functioning in training mode and real mode, enabling emergency response organizations to train more efficiently and effectively. This new fully integrated emergency management tool is called S3-FAST also known as Safety Support Systems - Field Assessment Survey Tool. (orig.)

    1986-09-01

    This paper is intended to assist the safety assessor within a regulatory body, or one working as a consultant, in assessing a given design of the Emergency Electrical Power System. Those non-electric power systems which may be used in a plant design to serve as emergency energy sources are addressed only in their general safety aspects. The paper thus relates closely to Safety Series 50-SG-D7 ''Emergency Power Systems at Nuclear Power Plants'' (1982), as far as it addresses emergency electric power systems. Several aspects are dealt with: the information the assessor may expect from the applicant to fulfill his task of safety review; the main questions the reviewer has to answer in order to determine the compliance with requirements of the NUSS documents; the national or international standards which give further guidance on a certain system or piece of equipment; comments and suggestions which may help to judge a variety of possible solutions

    The international nuclear community has a great understanding of the physical security needs relating to the prevention, detection, and response of malicious acts associated with nuclear facilities and radioactive material. International Atomic Energy Agency (IAEA) Nuclear Security Recommendations (INFCIRC_225_Rev 5) outlines specific guidelines and recommendations for implementing and maintaining an organization’s nuclear security posture. An important element for inclusion into supporting revision 5 is the establishment of a “Cyber Emergency Response Team (CERT)” focused on the international communities cybersecurity needs to maintain a comprehensive nuclear security posture. Cybersecurity and the importance of nuclear cybersecurity require that there be a specific focus on developing an International Nuclear CERT (NS-CERT). States establishing contingency plans should have an understanding of the cyber threat landscape and the potential impacts to systems in place to protect and mitigate malicious activities. This paper will outline the necessary components, discuss the relationships needed within the international community, and outline a process by which the NS-CERT identifies, collects, processes, and reports critical information in order to establish situational awareness (SA) and support decision-making

    In Fukushima disaster, a number of different UGVs, such as Packbots, Warriors, Quince, and Survey Runner, are used for monitoring, collecting data, inspection, and cleaning up. In utilizing UGVs in a nuclear emergency situation, one of serious problems is reliability of UGVs which is not sufficient yet for required mission completion. In this paper we surveyed failures and reliability of field UGVs and draw some important reliability considerations of UGVs for remote-response in a nuclear emergency situation. We think that the findings in this study will be helpful for developers or researchers of UGVs for nuclear emergency situations. We studied failures and reliability of UGVs used in search/rescue, military, and nuclear field by literature survey. The results showed that a state of art field UGVs can't be expected to complete an entire mission without failures, which leads to needs of reliability improvement of them. Though part of failure data from the surveyed studies were not enough detailed to get reliability matrix, some meaningful insights were found through analysis. Based on these insights, we draw some important considerations for reliability improvement of UGVs for an NPP emergency situation, and those reliability considerations are classified according to life cycle of a UGV for developers and researchers. Finally, there were not reported failures related to radiation environments in surveyed literature, but radiation tolerant control boards and sensors are easily anticipated in a NPP emergency situation. Therefore studies about the radiation-tolerant design and the use of radiation-tolerant components also should be considered for high reliability of UGVs for a NPP application

    Emergency response and preparedness (ERP) is an important components of a safety programme developed for any nuclear research centre or nuclear power plant to ensure that the facility can be operated safely and immediate response and actions can be taken to minimize the risk in case of unplanned events and incidences. ERP inclusion in the safety program has been made compulsory by most of the safety standard systems introduced currently including those of ISO 14000, OSHAS 18001 and IAEA. ERP has been included in the Nuclear Malaysia's Safety Health and Environment Management System (SHE-MS) for similar purpose. The ERP has been developed based on guidelines stipulated by AELB, IAEA, DOSH, Fire Brigade and Police Force, taking into consideration all possible events and incidences that can happen within the laboratories and irradiation facilities as a result of activities carried out by its personnel. This paper briefly describes the overall structure of the Nuclear Malaysia ERP, how it functions and being managed, and a brief historical perspective. However ERP is not easily implemented because of human errors and other weaknesses identified. Some ERP cases are analysed and assessed which based on the challenges, strategies and lessons learned from an ICT (Information and Communication Technology) perspective. Therefore, results of the analysis could then be used as inputs to develop a new system of Decision Support System (DSS) for ERP that is more effective in managing emergencies. This system is to be incorporated into the existing SHE-MS of Nuclear Malaysia. (Author)

    In late 1987, San Onofre nuclear generating station (SONGS) began an extensive upgrade of the units 2 and 3 emergency operating instructions (EOIs). The original intent of this program was to incorporate revised generic guidance and to correct problems that were identified by operators. While this program was in progress, the US Nuclear Regulatory Commission (NRC) conducted a series of audits of emergency operating procedure (EOP) development and maintenance programs as 16 commercial nuclear facilities in the United States. These audits included four stations with Combustion Engineering-designed nuclear steam supply systems. (One of these audits included a review of preupgrade SONGS units 2 and 3 EOIs.) Significant industrywide comments resulted from these audits. The NRC has stated its intent to continue the review and audit of EOIs and the associated maintenance programs at all US commercial nuclear facilities. The units 2 and 3 EOI upgrade program developed procedural improvements and procedural program maintenance improvements that address many of the existing audit comments that have been received by the industry. Other resulting improvements may be useful in minimizing NRC comments in future such audits. Specific improvements are discussed. The upgrade program resulted in benefits that were not originally anticipated. The results of this program can be of significant use by other utilities in addressing the industrywide concerns that have been raised in recent NRC audits of EOP development and maintenance programs

    1988-01-01

    Because of their inventories of radioactive materials nuclear facilities represent a hazard potential which, though comparable with that posed by other large technical facilities, demands particular protective measures to be taken. As a consequence of the extreme safety provisions, made, accidents with major impacts on the environment of nuclear facilities are excluded to the best human knowledge. However, as there are distinct limits to human planning and recognition, a residual risk remains despite all these precautions. In order to reduce that risk, recommendations for emergency protection in the environment of nuclear facilities have been drafted. To the extent in which measures are required outside the specific emergency protection plans apply which contain non-object related planning preparations. The recommendation also omits potential repercussions of nuclear accidents which might require measures in the sector of preventive health protection under the Radiation Protection Provisions act or the government measures to be taken. The recommendation is applied to German nuclear installations and those foreign installations whose proximity to the border requires planning measures to be taken on German territory in the sense of this recommendation.

    The basis for the Danish Nuclear Emergency Planning and Preparedness is described. Based on calculated scenarios of hypothetical core-melt accidents at foreign nuclear power plants close to the Danish border, requirements for a farfield (medium-field) preparedness organization are set up. Early alert and adequate information to the public are essential to credibility. Sheltering is the main protective measure against external radiation and inhalation during plume passage. Rapid monitoring of radiation levels and control of foodstuffs are provided for. Evacuation before passage of the plume is not foreseen, but temporary relocation from hot spots caused by local precipitation could be considered even in the farfield region

    This emergency plan is to serve as guidance for the protection measures to be taken whenever necessary. It establishes the duties of the different services and bodies, in accordance with their responsibilities under the national laws and regulations. The plan, which describes the general organisation, must be supplemented by intervention plans at the different action levels: by the provincial authorities, the communal authorities and the various services and institutions concerned. This plan mainly concerns large nuclear installations and transport of nuclear fuels and radioactive materials; however, lower risks from other activities are also covered. (NEA)

    After the accident of TEPCO's Fukushima Dai-ichi Nuclear Power Station occurred on March 11, 2011, actions for controlling the accident and protective actions for the residents like evacuation were taken. In parallel with this, it has been developed to reform the nuclear regulatory systems and the emergency preparedness and response systems in Japan. Especially the Nuclear Regulation Authority's Nuclear Emergency Preparedness and Response Guidelines were adopted with the introducing the basic concepts and the criteria on the basis of the IAEA's safety standards and differed greatly from the prior guidelines. Thus the arrangement of emergency response systems, resources and the operational procedures will be developed complying with according to the guidelines in municipalities around the nuclear power station sites. This work attempts to provide a plain explanation as possible for the regional officials and emergency workers about the basic concepts of the new guidelines. (author)

    In emergency situation of nuclear power plants, effective use of emergency operating procedures (EOPs) is a crucial part of the emergency response process. However, there are several problems in the emergency operating procedures because of the form of the written procedures. They are voluminous and complicate for effective references under high stress situation. Inevitably, it takes time that could be better spent employing measures to control and stabilize to select the correct procedures and apply the decision logic. In this study, a computerized supporting system has been developed to reduce the operator error possibility under emergency situations of nuclear power plant. Using on-line input parameters, the system can determine the status of the critical safety functions and can find appropriate procedures and necessary operator actions automatically. Moreover, the system can help the operator decision making in the core melt accident situation. By tracking the EOP in an on-line mode, most steps concerning checking or verifying plant state are processed automatically without operator participations. Therefore, the interactions between the system and the operator are simplified significantly and the possibility of human error is reduced

    To test the ability of the cytogenetic emergency network (CEN) of laboratories, currently under development across Canada, to provide rapid biological dosimetry using the dicentric assay for triage assessment, that could be implemented in the event of a large-scale radiation/nuclear emergency. A workshop was held in May 2004 in Toronto, Canada, to introduce the concept of CEN and recruit clinical cytogenetic laboratories at hospitals across the country. Slides were prepared for dicentric assay analysis following in vitro irradiation of blood to a range of gamma-ray doses. A minimum of 50 metaphases per slide were analyzed by 41 people at 22 different laboratories to estimate the exposure level. Dose estimates were calculated based on a dose response curve generated at Health Canada. There were a total of 104 dose estimates and 96 (92.3%) of them fell within the expected range using triage scoring criteria. Half of the laboratories analyzed 50 metaphases in emergency biological dosimetry. When this network is fully operational, it will be the first of its kind in Canada able to respond to radiological/nuclear emergencies by providing triage quality biological dosimetry for a large number of samples. This network represents an alternate expansion of existing international emergency biological dosimetry cytogenetic networks.

    Establishment of a national capability to respond to nuclear accidents and radiological emergency involves the planning, preparedness, readiness, assurance and response application of the necessary human and material resources to mitigate consequences of an emergency and protect workers, the public, the environment, and national security in the event of such accident. This obligation helps to prepare for the security of lives and properties during such accidents and it is binding and the responsibility of the operator to provide answers to fundamental questions about the nature of radiation, guidance on protecting against the harmful effects, detailed policies, procedures and training. The response to such emergency will involve highly specialized agencies and technical experts. For the Nigerian response capability to be well co-ordinated, the arrangements must be appropriately integrated with those for a conventional emergency. This project will discuss the hazard analysis based on the available inventory of radiation practices, facilities, installations, radiation sources and radioactive materials used in Nigeria. Based upon this analysis, a commensurate nuclear accident and radiological emergency planning and response capabilities has been proposed.(au)

    Full text: In the wake of the terrorist attacks of 9-11, the US Nuclear Regulatory Commission (NRC) took several actions to improve the security profile and emergency response of its licensees. In early 2002 the commission issued orders to its nuclear power plant licensees which included changes to emergency plans, the performance of staffing adequacy reviews, changes to augmentation practices and the establishment of alternative facilities. Since that time NRC has implemented a force-on-force exercise program that includes emergency response. This program has helped licensees improve their response by testing procedures under simulated attack conditions. More recently, licensees have begun a program to enhance drills and exercises through the use of security event based scenarios. These drills will enhance previous practice and focus on two emerging issues: improving the interface between emergency response, security response and operations during security events and recovery from the loss of plant equipment due to terrorist acts. Additional areas of enhancement such as protective actions for plant personnel will also be discussed and the status of actions to date will be provided. (author)

    The article reports selective results of a comparison between RODOS - an emerging decision support system for the management of nuclear emergencies in Europe developed by an international research consortium under EEC aegis, and a resident software package developed and maintained for similar purposes at IFIN-HH, Bucharest. Reproducible similarity patterns obtained in the output data distributions provide for simple normalising procedures that may ensure convergent radiological assessments. When properly consolidated on a sufficient scenario casuistry, such procedures could lend a certain resilience to domestic decision support tools over the interim lead time required by the full implementation of RODOS, or other major league, internationally accepted reference systems.

    It is necessary for the radiation protection system to broaden beyond radioactive dose, the view on impact of nuclear accidents, taking in consideration the psychological, social and economic determinants impacting the vulnerability of the exposed population, as well as the impacts of emergency countermeasures. It is strongly recommended to pursue strategies, approaches and services that will address these aspects within the general health protection system and will be applied before, during and after an emergency. The paper raises awareness and proposes a three-step development process for an integrated framework based on the social determinants of health approach. (authors)

    The Swedish Radiation Safety Authority (SSM) is trusted with the task of implementing Sweden's bilateral assistance to Russia, Ukraine, Georgia, Belarus and Armenia in the fields of reactor safety, nuclear waste management, nuclear non-proliferation as well as radiation protection and emergency preparedness. In these fields, SSM also participates in various projects financed by the European Union. The purpose of this project-oriented report is to provide the Swedish Government and other funding agencies as well as other interested audiences in Sweden and abroad with an encompassing understanding of our work and in particular the work performed during 2008. the activities are divided into four subfields: Nuclear waste management; Reactor safety; Radiation safety and emergency preparedness; and, Nuclear non-proliferation. SSM implements projects in the field of spent nuclear fuel and radioactive waste management in Russia. The problems in this field also exist in other countries, yet the concentration of nuclear and radioactive materials are nowhere higher than in north-west Russia. And given the fact that most of these materials stem from the Cold War era and remain stored under conditions that vary from 'possibly acceptable' to 'wildly appalling' it is obvious that Sweden's first priority in the field of managing nuclear spent fuel and radioactive waste lies in this part of Russia. The prioritisation and selection of projects in reactor safety are established following thorough discussions with the partners in Russia and Ukraine. For specific guidance on safety and recommended safety improvements at RBMK and VVER reactors, SSM relies on analyses and handbooks established by the IAEA in the 1990s. In 2008, there were 16 projects in reactor safety. SSM implements a large number of projects in the field of radiation protection and emergency preparedness. The activities are at a first glance at some distance from the activities covered and

    Currently the Swedish nuclear power plants are using diesel generator sets and to some extent gas turbines as their emergency AC power sources and batteries as their emergency DC power sources. In the laws governing Swedish nuclear activity, no specific power sources are prescribed. On the other hand, diversification of safety functions should be considered, as well as simplicity and reliability in the safety systems. So far the choices of emergency power sources have been similar between different power plants, and therefore this project investigated a number of alternative power sources and if they are suitable for use as emergency power on nuclear power plants. The goals of the project were to: - Define the parameters that are essential for rending a power source suitable for use at a nuclear power plant. - Present the characteristics of a number of power sources regarding the defined parameters. - Compile the suitability of the different power sources. - Make implementation suggestions for the less conventional of the investigated power sources. (unconventional in the investigated application) 10 different power sources in total have been investigated and to various degrees deemed suitable Out of the 10 power sources, diesel generators, batteries and to some extent gas turbines are seen as conventional technology at the nuclear power plants. In relation to them the other power sources have been assessed regarding diversification gains, foremost with regards to external events. The power sources with the largest diversification gains are: Internal steam turbine, Hydro power, Thermoelectric generators. The work should first and foremost put focus on the fact that under the right circumstances there are power sources that can complement conventional power sources and yield substantial diversification gains. This paper is a shortened version of the report 'Comparison between different power sources for emergency power supply at nuclear power plants'. The

    Preparedness and response capability for Nuclear and Radiological emergencies, existing world over, are mainly based on the requirement of responding to radiation emergency caused by nuclear or radiological accidents. Cosmos satellite accident, plutonium contamination at Polaris, nuclear accidents like Kystium, Windscale, TMI and Chernobyl, radiological accidents at Goiania etc have demonstrated the requirement of improved radiation monitoring techniques. For quick decision making, state of the art monitoring methodology which can support quantitative and qualitative impact assessment is essential. Evaluation of radiological mapping of the area suspected to be contaminated needs ground based as well as aerial based monitoring systems to predict the level of radioactive contamination on ground. This will help in delineating the area and deciding the required countermeasures, based on the quantity and type of radionuclides responsible for it. The response can be successful with the effective use of i) Early Warning System ii) Mobile Monitoring System and iii) Aerial Gamma Spectrometric System. Selection of the monitoring methodology and survey parameters and assessment of situation using available resources etc. are to be optimized depending on the accident scenario. Recently, many countries and agencies like IAEA have expressed the requirement for responding to other types of nuclear/radiological emergencies i.e, man made radiation emergency situatio
