    In the framework of the French regulation on nuclear materials possession, the first liability is the one of operators who have to know at any time the quantity, quality and localization of any nuclear material in their possession. This requires an organization of the follow up and of the inventory of these materials together with an efficient protection against theft or sabotage. The French organization foresees a control of the implementation of this regulation at nuclear facilities and during the transport of nuclear materials by the minister of industry with the sustain of the institute of radiation protection and nuclear safety (IRSN). This article presents this organization: 1 - protection against malevolence; 2 - national protection and control of nuclear materials: goals, administrative organization, legal and regulatory content (authorization, control, sanctions), nuclear materials protection inside facilities (physical protection, follow up and inventory, security studies), protection of nuclear material transports (physical protection, follow up), control of nuclear materials (inspection at facilities, control of nuclear material measurements, inspection of nuclear materials during transport); 3 - international commitments of France: non-proliferation treaty, EURATOM regulation, international convention on the physical protection of nuclear materials, enforcement in France.

    Full text: I. Program goal and organization - In this paper we review the Cooperative US-Russia Program of Nuclear Material Protection, Control and Accounting (MPC and A), whose goal is to reduce the risk of nuclear weapons proliferation by strengthening systems of MPC and A; thereby the Program enhances US national security. Based on this goal, the technical objective is to enhance, through US technical cooperation, the effectiveness of MPC and A systems at Russian sites with weapons-usable nuclear material, i.e. plutonium and highly enriched uranium. The Program exists because the extensive social, political and economic changes in Russia arising from the dissolution of the Soviet Union have increased the risk that these materials would be subject to theft or other misuse, with potentially grave consequences. On the US side, the MPC and A Program is administered by the US Department of Energy (DOE) National Nuclear Security Administration through the DOE national laboratories and other contractors. On the Russian side, the Program is administered by the Russian Ministry of Atomic Energy (Minatom) through its nuclear sites, by the regulatory agency Gosatomnadzor, and by nuclear sites not under Minatom. To carry out the Program objective, the DOE national laboratories consummate contracts with the Russian sites to implement agreed MPC and A upgrades. Deciding on what upgrades to perform depends on a cooperative analysis of site characteristics, materials, and vulnerabilities by joint US and Russian teams. Once the upgrades are agreed, the DOE laboratories supply technical and financial support and equipment to the Russian sites. The staff of the Russian sites do the work, and the US team members monitor the work through some combination - according to contract - of direct observation and reports, photographs and videotape supplied by the staff of the Russian sites.

    Full text: The French Government set up a national safeguards system under the authority of the Ministry for Industry to control nuclear materials within national boundaries and to ensure physical protection for nuclear materials, even for the small quantities held by users in industrial, medical and research areas. The main nuclear materials detained by small owners are depleted uranium and thorium. These materials are present in manufactured equipment (radiation shielding in industrial gammagraphy and radiotherapy, collimation devices and other accessories) which are used or unused, which may be damaged or left as scraps. The French protection and control system of nuclear materials is an original system based on detailed and comprehensive regulations, taking into account in a specific way the small users of nuclear materials. The decree no. 81-512 of 12 May 1981 establishes three different regimes: licensing, declaration and exemption, according to the nature and quantity of nuclear materials involved. Typically, the declaration regime applies to quantities of depleted uranium or thorium, greater than 1 kg and lower than 500 kg. The Order of 14 March 1984 sets the requirements related to the control and physical protection of nuclear materials in the frame of the declaration regime. A declaration must be established every year by the operator and sent to the IPSN, acting as technical support body of the national authority. This declaration provides the stock of all nuclear materials held by the operator and stock variations occurred during the previous year, including the identification of senders and receivers. Before fulfilling its annual declaration, the operator must carry out a physical inventory of all nuclear material, both used and unused. The declaration also describes the main features concerning facility layout related to surveillance and physical protection of materials. With respect to physical protection requirements, nuclear materials should be

    The nuclear danger can be reduced by a system for global management, protection, control, and accounting as part of a disposition program for special nuclear materials. The development of an international fissile material management and control regime requires conceptual research supported by an analytical and modeling tool that treats the nuclear fuel cycle as a complete system. Such a tool must represent the fundamental data, information, and capabilities of the fuel cycle including an assessment of the global distribution of military and civilian fissile material inventories, a representation of the proliferation pertinent physical processes, and a framework supportive of national or international perspective. They have developed a prototype global nuclear material management and control systems analysis capability, the Global Nuclear Material Control (GNMC) model. The GNMC model establishes the framework for evaluating the global production, disposition, and safeguards and security requirements for fissile nuclear material

    The threat of nuclear weapons proliferation is a problem of global concern. International efforts at nonproliferation focus on preventing acquisition of weapons-grade nuclear materials by unauthorized states, organizations, or individuals. Nonproliferation can best be accomplished through international cooperation in the application of advanced science and technology to the management and control of nuclear materials. Computerized systems for nuclear material protection, control, and accountability (MPC and A) are a vital component of integrated nuclear safeguards programs. This paper describes the progress of scientists in the United States and former Soviet Republics in creating customized, computerized MPC and A systems. The authors discuss implementation of the Core Material Accountability System (CoreMAS), which was developed at Los Alamos National Laboratory by the US Department of Energy and incorporates, in condensed and integrated form, the most valuable experience gained by US nuclear enterprises in accounting for and controlling nuclear materials. The CoreMAS approach and corresponding software package have been made available to sites internationally. CoreMAS provides methods to evaluate their existing systems and to examine advantages and disadvantages of customizing CoreMAS or improving their own existing systems. The sites can also address crucial issues of software assurance, data security, and system performance; compare operational experiences at sites with functioning computerized systems; and reasonably evaluate future efforts. The goal of the CoreMAS project is to introduce facilities at sites all over the world to modern international MPC and A practices and to help them implement effective, modern, computerized MPC and A systems to account for their nuclear materials, and thus reduce the likelihood of theft or diversion. Sites are assisted with MPC and A concepts and the implementation of an effective computerized MPC and A system

    Full text: Brazil started protecting its nuclear materials soon after the end of the World War II, when the Combined Development Trust intended to control the world supply of uranium and thorium. This happened in 1944, but on December 27, 1946, an amendment to the report of Committee II of the United Nations established that the international ownership of the unexplored uranium and thorium would not be mandatory. Brazil nationalized its thorium and uranium reserves in 1951. The Brazil-Germany agreement signed in 1975 enhanced the need for Brazilian nuclear safeguards and security. The physical protection (PP) and control of nuclear materials (CNM) became activities under the supervision of the Brazilian military forces. The System for Protection of the Brazilian Nuclear Program (SIPRON), established on 7 October 1980, took over the responsibilities for PP and other aspects of the Brazilian nuclear program. The central organ of SIPRON was the Brazilian National Security Council (CSN). The Brazilian Nuclear Energy Commission (CNEN) was in charge of coordinating, among others, the PP sector. Earlier that year - on 3 March 1980 - the Convention on the Physical Protection of Nuclear Material (CPPNM) was signed simultaneously in New York and Vienna. The Brazilian congress approved the CPPNM on 27 November 1984, and the Brazilian government deposited the ratification letter on 17 October 1985. On 16 April 1991 the Brazilian government issued a decree to enforce the CPPNM in the Brazilian territory. CNEN published the regulatory documents NE - 2.01 on 19 April 1996, and NN - 2.02 on 21 September 1999 for PP, and CNM, respectively. CNEN has the ultimate responsibility to enforce these regulations. The operational aspects of PP and CNM in Brazil are still improving. Potential nuclear terrorism for example needs to be examined. Activities concerning training personnel and implementing PP and CNM will be described in the paper. (author)

    1975-01-01

    Full text: An Advisory Group met to consider the up-dating and extension of the Recommendations for the Physical Protection of Nuclear Material, produced in 1972. Twenty-seven experts from 11 countries and EURATOM were present. Growing concern has been expressed in many countries that nuclear material may one day be used for acts of sabotage or terrorism. Serious attention is therefore being given to the need for States to develop national systems for the physical protection of nuclear materials during use, storage and transport throughout the nuclear fuel cycle which should minimize risks of sabotage or theft. The revised Recommendations formulated by the Advisory Group include new definitions of the objectives of national systems of physical protection and proposals for minimizing possibilities of unauthorized removal and sabotage to nuclear facilities. The Recommendations also describe administrative or organizational steps to be taken for this purpose and the essential technical requirements of physical protection for various types and locations of nuclear material, e.g., the setting up of protected areas, the use of physical barriers and alarms, the need for security survey, and the need of advance arrangements between the States concerned in case of international transportation, among others.

    The US Department of Energy (DOE) is cooperating with Russia, the Newly Independent States (NIS), and the Baltics to help prevent the proliferation of nuclear weapons through the improvement of national systems of nuclear material protection, control, and accounting (MPC and A). US cooperation with Russia is carried out under the DOE MPC and A Program and the Nunn-Lugar funded Cooperative Threat Reduction program for Russia. Presidential Decision Directive (PDD)-41 designated DOE as the government agency with primary responsibility for MPC and A efforts in Russia, the NIS, and Baltics. Cooperation is conducted in coordination with the Nuclear Regulatory Commission (NRC) for the development of a strong, independent national regulatory agency in Russia. DOE also coordinates these efforts with the European Community and other countries. DOE''s cooperation under the MPC and A program with Russia includes aggressive near-term activities to better secure nuclear materials through MPC and A system upgrades at facilities. Simultaneously, DOE is supporting Russia in its long-term goal of implementing upgraded MPC and A systems that can be maintained and supported from indigenous resources. Projects include the development of national regulations and laws, training of trainers, the development of a computerized federal information system, and other related tasks. NRC''s role in these efforts includes regulatory development activities, such as licensing and inspection program development, and related training. This paper provides an overview of the activities undertaken through DOE-Russian cooperation on MPC and A and how they complement each other

    Since 1996, the Ural Electrochemical Integrated Plant (UEIP) located in the town of Novouralsk, Russia, (previously known as Sverdlovsk-44) and the United States Department of Energy (U.S. DOE) have been cooperating under the Nuclear Material Protection, Control and Accounting (MPC and A) Program. Because UEIP is involved in the processing of highly enriched uranium (HEU) into low enriched uranium (LEU), and there are highly enriched nuclear materials on its territory, the main goal of the MPC and A cooperation is to upgrade those systems that ensure secure storage, processing and transportation of nuclear materials at the plant. UEIP has completed key upgrades (equipment procurement and installation) aimed at improving MPC and A systems through significant investments made by both the U.S. DOE and UEIP. These joint cooperative efforts resulted in bringing MPC and A systems into compliance with current regulations, which led to nuclear material (NM) theft risk reduction and prevention from other unlawful actions with respect to them. Upon the U.S. MPC and A project team's suggestion, UEIP has developed an equipment inventory control process to track all the property provided through the MPC and A Program. The UEIP process and system for managing equipment provides many benefits including: greater ease and efficiency in determining the quantities, location, maintenance and repair schedule for equipment; greater assurance that MPC and A equipment is in continued satisfactory operation; and improved control in the development of a site sustainability program. While emphasizing UEIP's equipment inventory control processes, this paper will present process requirements and a methodology that may have practical and helpful applications at other sites.

    The Institute of Physics and Power Engineering (IPPE) is a leading research center under the Ministry of Atomic Energy of the Russian Federation. IPPE encompasses many installations and many specialists who perform fundamental and applied investigations in nuclear power and technology for the national nuclear program. IPPE has a key role in the national nuclear material protection, control, and accounting (MPC ampersand A) system both as a nuclear facility and also as a training center for MPC ampersand A. As a participant in the US-Russian Laboratory-to-Laboratory Cooperative Program in MPC ampersand A, IPPE is conducting several tasks in collaboration with US Department of Energy national laboratories. The main goal of these tasks is the rapid improvement of MPC ampersand A at one of the most sensitive operating IPPE installations, the BFS critical facility, which has large numbers of fuel items containing highly enriched uranium and weapons-grade plutonium. After the completion of several test, evaluation, and demonstration tasks, it is hoped that the tested and adopted methods and procedures can be applied not only to the entire population of BFS fuel items, but also to other facilities at IPPE and other Russian nuclear institutes and operating facilities. The collaborative tasks cover seven areas: computerized nuclear material accounting, entry control and portals, item control and inventory, design evaluation and analysis, gamma and neutron assay, an integrated demonstration, and physical protection elements and test bed

    Results of the tests have confirmed the expedience of certification of the equipment, especially imported items. For the use of imported equipment at Russian facilities, it is justified to accommodate the accompanying documents thereto for the Russian standards. Equipment items shipped to Russia should be prepared for the certification tests and/or operation. When taking decision on the certification of imported equipment, it is expedient to preliminarily estimate the instrument's parameters and its operation in Russia. To solve the question whether the imported equipment is usable for Russia and what engineering support and maintenance is needed for its operation, it would be justified to create the Center for engineering support of instruments to be used for nuclear material protection, control and accounting on the basis of one of institutes dealing with the development of instruments for these application [ru

    UEIP has been working on a comprehensive sustainability program that includes establishing a site sustainability working group, information gathering, planning, organizing, developing schedule and estimated costs, trhough joint UEIP-US DOE/NNSA National Laboratory sustainability contracts. Considerable efforts have been necessary in the sustainability planning, monitoring, and control of the scope of work using tools such as Microsoft Excel, Microsoft Project and SAP R/3. While information interchanges within the sustainability program provides adequate US assurances that US funds are well spent through its quarterly reporting methodology, proper information security and protection measures are taken throughout the process. Decommissioning of outdated equipment has also become part of determining sustainability requirements and processes. The site's sustainability program has facilitated the development of a transition plan toward eventual full Russian funding of sustaining nuclear security upgrades.

    The Department of Energy has defined a safeguards system to be an integrated system of physical protection, material accounting and material control subsystems designed to deter, prevent, detect, and respond to unauthorized possession, use, or sabotage of SNM. In practice, safeguards involve the development and application of techniques and procedures dealing with the establishment and continued maintenance of a system of activities. The system must also include administrative controls and surveillance to assure that the procedures and techniques of the system are effective and are being carried out. The control of nuclear material is critical to the safeguarding of nuclear materials within the United States. The U.S. Department of Energy includes as part of material control four functional performance areas. They include access controls, material surveillance, material containment and detection/assessment. This paper will address not only these areas but also the relationship between material control and other safeguards and security functions

    This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The nuclear danger can be reduced by a system for global management, protection, control, and accounting as part of an international regime for nuclear materials. The development of an international fissile material management and control regime requires conceptual research supported by an analytical and modeling tool which treats the nuclear fuel cycle as a complete system. The prototype model developed visually represents the fundamental data, information, and capabilities related to the nuclear fuel cycle in a framework supportive of national or an international perspective. This includes an assessment of the global distribution of military and civilian fissile material inventories, a representation of the proliferation pertinent physical processes, facility specific geographic identification, and the capability to estimate resource requirements for the management and control of nuclear material. The model establishes the foundation for evaluating the global production, disposition, and safeguards and security requirements for fissile nuclear material and supports the development of other pertinent algorithmic capabilities necessary to undertake further global nuclear material related studies

  13. The Physical Protection of Nuclear Material

    1993-01-01

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international cooperation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and materials, particularly when such materials are transported across national frontiers

    The Siberian Chemical Combine (SKhK) is the largest multifunction nuclear production facility in the Russian nuclear complex. Until recently, it produced and processed special nuclear material for the Russian Defense Ministry. SKhK and its US partners in the Department of Energy (DOE) US/Russian Materials Protection, Control, and Accountability (MPC and A) Program are nearing completion of the initial MPC and A upgrades at the six SKhK plant sites that were begun three years ago. Comprehensive enhancements to the physical protection and access control systems are progressing on a site-wide basis while a comprehensive MC and A system is being implemented at the Radiochemical Plant site. SKhK now produces thermal and electrical power, enriches uranium for commercial reactor fuel, reprocesses irradiated fuel, converts high-enriched uranium metal into high-enriched oxide for blending into reactor-grade, low-enriched uranium, and manufactures civilian products. The authors review the progress to date and outline plans for continuing the work in 1999

    Because of the increasing incidence of terrorism, there is growing concern that nuclear materials and facilities need improved physical protection against theft, diversion, or sabotage. Physical protection systems for facilities or transportation which have balanced effectiveness include information systems, access denial systems, adequate and timely response, recovery capability, and use denial methods for despoiling special nuclear materials (SNM). The role of these elements in reducing societal risk is described; however, it is noted that, similar to nuclear war, the absolute risks of nuclear theft and sabotage are basically unquantifiable. Sandia Laboratories has a major Energy Research and Development Administration (ERDA) role in developing advanced physical protection systems for improving the security of both SNM and facilities. These activities are surveyed. A computer simulation model is being developed to assess the cost-effectiveness of alternative physical protection systems under various levels of threat. Improved physical protection equipment such as perimeter and interior alarms, secure portals, and fixed and remotely-activated barriers is being developed and tested. In addition, complete prototype protection systems are being developed for representative nuclear facilities. An example is shown for a plutonium storage vault. The ERDA safe-secure transportation system for highway shipments of all significant quantities of government-owned SNM is described. Adversary simulation as a tool for testing and evaluating physical protection systems is discussed. A list of measures is given for assessing overall physical protection system performance. (auth)

    educational problems in area of nuclear materials physical protection, control and accountability (MPC and A) in Russia. General scheme of Russian educational system is considered with main emphasis on the directions under implementation now, namely academic training system, re-training system and specialists qualification upgrade system in MPC and A area. Russian academic training system consists of the educational programs at various levels: Bachelor of Sciences, Master of Sciences, Specialist (also referred to as an Engineer Degree), and professional re-training of the personnel already working in the nuclear field. Currently, only the Master of Sciences Graduate Program is completely developed for the students training. This is taking place at Moscow Engineering Physics Institute (State University, MEPhI), where the fourth generation of Masters has graduated from in May 2003. The graduates are now working at nuclear-related governmental agencies, non-governmental organizations, universities, and nuclear facilities. Development of the system to produce academically trained Russian MPC and A personnel is therefore well underway. MEPhI's MPC and A Engineering Degree Program which currently under development is considered in the paper. Analysis of MPC and A needs at Russian nuclear facilities has demonstrated the Engineering Degree Program is the best way to satisfy these needs and the resulting demands for MPC and A specialists at Russian nuclear enterprises. This paper discusses specific features of the Engineering Degree training required by Russian education legislation and the Russian system of quality control as applied to the training process. The paper summarizes the main joint actions undertaken during the past three years by MEPhI in collaboration with the US Department of Energy and US national laboratories to develop the MPC and A Engineering Degree Program in Russia. These actions include opening a new Engineering Degree specialty, Safeguards and Nonproliferation

    Full text: The Federal law 'On The Use Of Atomic Energy' containing the section on physical protection of nuclear materials and nuclear facilities was issued in 1995 in Russian Federation. This document became the first federal level document regulating the general requirements to physical protection (PP). The federal PP rules developed on the base of this law by Minatom of Russia and other federal bodies of the Russian Federation were put in force by the government of Russia in 1997. The requirements of the convention on physical protection of nuclear materials (INFCIRC 274) and the modern IAEA recommendations (INFCIRC/225/Rev.4) are taken into account in the PP rules. Besides, while developing the PP rules the other countries' experience in this sphere has been studied and taken into account. The PP rules are action-obligatory for all juridical persons dealing with nuclear activity and also for those who are coordinating and monitoring this activity. Nuclear activity without physical protection ensured in accordance with PP rules requirements is prohibited. The requirements of PP Rules are stronger than the IAEA recommendations. The PP rules are establishing: physical protection objectives; federal executive bodies and organizations functions an implementation of physical protection; categorization of nuclear materials; requirements for nuclear materials physical protection as during use and storage as during transportation; main goals of state supervision and ministry level control for physical protection; notification order about the facts of unauthorized actions regarding nuclear materials and facilities. Besides the above mentioned documents, there were put in force president decrees, federal laws and regulations in the field of: counteraction to nuclear terrorism; interactions in physical protection systems; military and ministerial on-site guard activities; information protection. By the initiative of Minatom of Russia the corrections were put into the

    Full text: The State system for nuclear material control consists of three integral components. The efficiency of each is to guarantee the non-proliferation regime in Kazakhstan. The components are the following: accounting, export and import control and physical protection of nuclear materials. First, the implementation of the goals of accounting and control bring into force, by the organization of the system for accounting and measurement of nuclear materials to determine present quantity. Organizing the accounting for nuclear material at facilities will ensure the efficiency of accountancy and reporting information. This defines the effectiveness of the state system for the accounting for the Kazakhstan's nuclear materials. Currently, Kazakhstan's nuclear material is fully safeguarded in designated secure locations. Kazakhstan has a nuclear power plant, 4 research reactors and a fuel fabrication plant. The governmental information system for nuclear materials control consist of two level: Governmental level - KAEA collects reports from facilities and prepares the reports for International Atomic Energy Agency, keeping of supporting documents and other necessary information, a data base of export and import, a data base of nuclear material inventory. Facility level - registration and processing information from key measurement points, formation the facility's nuclear materials accounting database. All facilities have computerized systems. Currently, all facilities are safeguarded under IAEA safeguarding standards, through IAEA inspections. Annually, IAEA verifies all nuclear materials at all Kazakhstan nuclear facilities. The government reporting system discloses the existence of all nuclear material and its transfer intended for interaction through the export control system and the nuclear control accounting system. Nuclear material export is regulated by the regulations of the Nuclear Export Control Law. The standard operating procedure is the primary means for

    Nuclear material accounting systems were examined and compared to financial double-entry accounting systems. Effective nuclear material accounting systems have been designed using the principles of double-entry financial accounting. The modified double-entry systems presently employed are acceptable if they provide adequate control over the recording and summarizing of transactions. Strong internal controls, based on principles of financial accounting, can help protect nuclear materials and produce accurate, reliable accounting data. An electronic data processing system can more accurately maintain large volumes of data and provide management with more current, reliable information

    Issues related to nuclear material control and accounting and illegal dealing in these materials were discussed at the April 19--20, 1996 Moscow summit meeting (G7 + Russia). The declaration from this meeting reaffirmed that governments are responsible for the safety of all nuclear materials in their possession and for the effectiveness of the national control and accounting system for these materials. The Russian delegation at this meeting stated that ''the creation of a nuclear materials accounting, control, and physical protection system has become a government priority''. Therefore, in order to create a government nuclear material control and accounting system for the Russian Federation, it is critical to study the structure, operating principles, and regulations supporting the control and accounting of nuclear materials in the national systems of nuclear powers. In particular, Russian specialists have a definite interest in learning about the National Nuclear Material Control and Accounting System of the US, which has been operating successfully as an automated system since 1968

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

    The Ministry of the Russian Federation for Atomic Energy (MINATOM) and the US Department of Energy (DOE) are engaged in joint, cooperative efforts to reduce the likelihood of nuclear proliferation by enhancing Material Protection, Control and Accounting (MPC&A) systems in both countries. Mayak Production Association (MPA) is a major Russian nuclear enterprise within the nuclear complex that is operated by MINATOM. This paper describes the nature, scope, and status of the joint, cooperative efforts to enhance existing MPC&A systems at MPA. Current cooperative efforts are focused on enhancements to the existing MPC&A systems at four plants that are operated by MPA and that produce, process, handle and/or store proliferation-sensitive nuclear materials.

  2. Croatian National System of Nuclear Materials Control

    1998-01-01

    In the process of economic and technological development of Croatia by using or introducing nuclear power or in the case of international co-operation in the field of peaceful nuclear activities, including international exchange of nuclear material, Croatia should establish and implement National System of Nuclear Materials Control. Croatian National System of accounting for and control of all nuclear material will be subjected to safeguards under requirements of Agreement and Additional Protocol between the Republic of Croatia and the International Atomic Energy Agency (IAEA) for the Application of Safeguards in Connection with the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The decision by NPT parties at the 1995 NPT Review and Extension Conference to endorse the Fullscope IAEA Safeguards Standard (FSS) as a necessary precondition of nuclear supply means that states are obliged to ensure that the recipient country has a FSS agreement in place before any nuclear transfer can take place (Ref. 1). The FSS standard of nuclear supply is a central element of the Nuclear Suppliers Group (NSG) Guidelines which the NSG adopted in 1992 and should be applied to members and non-members of the NSG. The FSS standard of nuclear supply in general allows for NPT parties or countries which have undertaken the same obligations through other treaty arrangements, to receive favourable treatment in nuclear supply arrangements. However, the Iraqi experience demonstrate that trade in nuclear and dual-use items, if not properly monitored, can contribute to a nuclear weapons program in countries acting contrary to their non-proliferation obligation. Multilateral nuclear export control mechanisms, including the FSS supply standard, provide the basis for co-ordination and standardisation of export control measures. (author)

  3. The Physical Protection of Nuclear Material and Nuclear Facilities

    International Nuclear Information System (INIS)

    1999-08-01

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international co-operation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and nuclear materials, particularly when such materials are transported across national frontiers

    Physical protection has played an essential role in ensuring the implementation of global nuclear nonproliferation framework for the past decades. Since the 9/11 terrorist attacks upon the United States, physical protection has also played the same role in combating nuclear terrorism. Nowadays, physical protection is more highlighted than before with global nuclear security regimes more strengthened. Ever since the commencement of the first nuclear power plant in 1978, Korea has devotedly implemented international physical protection standards as an exemplary country in respect of the peaceful use of nuclear energy. The Korean government has recently reinforced national physical protection policy including the revision of laws and regulations. In this paper, the national policy is extensively reviewed and additional measures are proposed to enhance the national physical protection system. (orig.)

    Possibility on unauthorized removal (theft) of nuclear material by a facility insider is a recognized as a serious threat. An insider could take advantage or knowledge of control system and access to nuclear material to intercept facility's system designed to protect theft of nuclear material by an insider. This paper will address how the facility level Nuclear Material Accounting and Control (NMAC) System should be designed and implemented to enhance deterring and detect theft of nuclear material by a facility insider.

    Fuzzy controllers are applied to predicting and modeling a time series, with particular emphasis on anomaly detection in nuclear material inventory differences. As compared to neural networks, the fuzzy controllers can operate in real time; their learning process does not require many iterations to converge. For this reason fuzzy controllers are potentially useful in time series forecasting, where the authors want to detect and identify trends in real time. They describe an object-oriented implementation of the algorithm advanced by Wang and Mendel. Numerical results are presented both for inventory data and time series corresponding to chaotic situations, such as encountered in the context of strange attractors. In the latter case, the effects of noise on the predictive power of the fuzzy controller are explored

    1998-11-01

    As a result of major political and societal changes in the past several years, methods of nuclear material control may no longer be as effective as in the past in Russia, the Newly Independent States (NIS), and the Baltic States (BS). The objective of the Department of Energy (DOE) Material Protection, Control, and Accounting Program (MPC and A) is to reduce the threat of nuclear proliferation by collaborating with Russia, NIS, and BS governments to promote western-style MPC and A. This cooperation will improve the MPC and A on all weapons useable nuclear materials and will establish a sustainable infrastructure to provide future support and maintenance for these technology-based improvements. Nuclear materials of proliferation concern include materials of the types and quantities that can be most easily and directly used in a nuclear weapon. Sabotage of nuclear material is an event of great concern and potentially disastrous consequences to both the US and the host country. However, sabotage is currently beyond the scope of program direction and cannot be used to justify US-funded MPC and A upgrades. Judicious MPC and A upgrades designed to protect against insider and outsider theft scenarios would also provide addition, although not comprehensive, protection against saboteurs. This paper provides some suggestions to establish consistency in prioritizing system-enhancement efforts at nuclear material facilities. The suggestions in this paper are consistent with DOE policy and directions and should be used as a supplement to any policy directives issued by NN-40, DOE Russia/NIS Task Force.

    The system of accountancy for and control of nuclear material in the German Democratic Republic (GDR) with its legal bases and components is embedded in the overall State system of protection in the peaceful uses of nuclear energy. As the competent State authority, the Nuclear Safety and Radiation Protection Board of the GDR is also responsible for meeting the GDR's national and international tasks in the control of nuclear material. At enterprise level, the observance of all safety regulations for nuclear material, including the regulations for the control, is within the responsibility of managers of establishments, which are in any way concerned with the handling of nuclear material. To support managers and to function as internal control authorities, nuclear material officers have been appointed in these establishments. Design information, operating data, physical inventory of nuclear material and the respective enterprise records and reports are subject to State control by the Nuclear Material Inspectorate of the Nuclear Safety and Radiation Protection Board. This Inspectorate keeps the central records on nuclear material, forwards reports and information to, and maintains the necessary contacts with, the IAEA. For the nuclear material in the GDR four material balance areas have been established for control purposes. To rationalize central recording and reporting, electronic data processing is increasingly made use of. In a year-long national and international control of nuclear material, the State control system has stood the test and successfully co-operates with the IAEA. (author)

    Federal regulations prepared by the Nuclear Regulatory Commission and published in the Federal Register require licensees to take appropriate action to protect the health and safety of the public from unauthorized use of special nuclear material (SNM), which includes plutonium, uranium-233, and highly enriched uranium. Crime countermeasures for compliance with these regulations are an important part of the guidance that is provided by the NRC's Office of Standards Development. The use of crime countermeasures and protective devices is intended to prevent the unauthorized diversion of material and to aid in the detection of diversion should it be attempted. Plant and equipment designs should incorporate both electronic and physical security measures for protection of SNM. This applies to facilities and equipment for reprocessing, fabrication, and transportation of SNM. The protection systems include physical barriers, access controls, intrusion detection devices, surveillance devices, central alarm stations, communications, and response capability. Acceptable security measures and devices applicable to protected areas, material access areas, vital areas, vital equipment, and transportation vehicles have been presented in Regulatory Guides.

    Full text: Physical protection of nuclear material against diversion and stealing presents a major step to prevent abuse of nuclear material for military or terrorist purposes. If such material had been diverted, however, and discovered by border traffic control, police control or other methods of investigation, identifying the site and time of diversion is of utmost importance to ensure that the point of possible diversion is closed and the possible delivery and end-use point becomes known. The quicker and more comprehensive these investigations are performed, the greater are the chances to find the criminal persons and the point of diversion. The paper, therefore, deals with fingerprinting methods used to obtain enough and comprehensive background information for investigators to find out the source of diversion and the channels through which it might have reached the point of discovery and the possible point of ultimate destination (end-use of the material). On the example of the round-robin test for the identification of illicit nuclear material performed by EURATOM in 1999, and the conclusions obtained by our laboratory it is demonstrated that a high amount of information can be drawn from a single sample and that this information can be used by investigators world-wide to find the point of origin of the material and its possible point of diversion. The set of information is segmented into 3 different levels: information gained in the first 24 hours after arrival of the unknown material, information gained up to one week after uptake and information gained up to one month after. The first information is to inform the investigators about the hazard and the relevance of the material, about preliminary investigation results and support the investigating judge on the justification to further detain the person(s). The second information should contain more detail on the material and the possible point of diversion and assist the investigators to decide on proper

Consequently, a comprehensive review of INFCIRC/225 has not been conducted since 1989. Consequently, a meeting of national experts was convened from 2-5 June 1998 and from 27-29 October 1998 for a thorough review of INFCIRC/225/Rev.3. The revised document reflects the recommendations of the national experts to improve the structure and clarity of the document and to take account of improved technology and current international and national practices. In particular, a chapter has been added which provides specific recommendations related to sabotage of nuclear facilities and nuclear material. As a result of this addition, the title has been changed to 'The Physical Protection of Nuclear Material and Nuclear Facilities'. The recommendations presented in this IAEA document reflect a broad consensus among Member States on the requirements which should be met by systems for the physical protection of nuclear materials and facilities.

    International Nuclear Information System (INIS)

    Steinhausler, F.; Bunn, G.

    2002-01-01

    Full text: The main reason why national physical protection (PP) systems for nuclear and other radioactive material need to be strengthened further is that, after the attacks on the US on 11 September 2001, the threat of dangerous, suicidal radiological and nuclear terrorism can no longer be excluded as a possibility. Existing PP systems were not designed to deal with the threat of suicidal terrorists having the numbers, skills, training, and resources available to the commandos attacking on 11 September. Moreover, there are no mandatory international standards for domestic PP systems for nuclear or radioactive material, and this has produced great variation in protection provided from country to country. IAEA recommended standards, while useful, were not designed with the new terrorist threat in mind. Moreover, they are often not followed in practice. The result is inadequate protection against the new form of terrorism in most countries. The Director General of the IAEA expressed a similar view after 11 September, but achieving a consensus to amend the Convention on the Physical Protection of Nuclear Material (CPPNM) to require specific standards of protection for different amounts and kinds of nuclear material used or stored domestically (not in international transport) has been impossible in the year since 11 September. In the case of radiological materials, a new effort to provide required international standards for protection against the new form of terrorism has not begun. In the summer of 2001, leaders of the G-8 countries agreed to a Global Partnership to prevent the new terrorists from acquiring nuclear and radiological as well as other materials related to weapons of mass destruction. Perhaps in part because of the failure to date to achieve agreement on an effective amendment to the CPPNM, the first principle of this partnership is to strengthen 'multilateral treaties and other instruments whose aim is to prevent the proliferation or illicit

    International Nuclear Information System (INIS)

    2001-01-01

    Effective control of nuclear material is fundamentally important to the credibility and reliability of the nuclear non-proliferation regime. Under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), international safeguards are applied to non-nuclear- weapon State Parties for the purpose of verifying compliance with their undertakings not to seek to acquire nuclear weapons or explosive devices by assuring that safeguarded nuclear activities and material are not diverted from their intended peaceful use. Reflecting the sovereign State basis upon which the international system rests, the control and protection of nuclear materials within the State are the responsibility of the national authority. This division of responsibility between international verification of non-diversion on the one hand and national responsibility for material protection on the other has worked quite well over time. But it has not created a seamless web of fully effective control over nuclear material. 34 In so far as safeguards are concerned, six points are to be made: 1. INFCIRC/153 Agreements: Completion by all NPT Parties of the required safeguards agreements with the IAEA. Fifty States Party to the NPT still have not entered into treaty-obligated safeguards agreements with the IAEA. 2. Adherence by all States having full-scope safeguards INFCIRC/540. As noted, very few States have thus far negotiated and implemented the strengthened safeguards arrangements. 3. United Nations Security Council action to take its 1992 assertions (related to compliance and enforcement) on proliferation and safeguards a step further. 4. Non-NPT Party support for international Safeguards. 5. Safeguards financing. 6. IAEA Access to export license information

    Full text: The first and the second Russian international conferences on MPC+A held in 1997 and 2000 correspondingly, under the Russian-American program of the MPC+A cooperation proved to be a useful tool for Russian, American specialists and experts from a number for sharing their opinions and exchanging achievements in this sensitive area. The recommendation to hold the next third MPC+A conference in Russia was formulated in the final document of the second conference in 2000. The results of the Russian-American cooperation are especially valuable since they demonstrate how much can be done due to the joint efforts of even previously adversarial countries. This paper gives a summary of the main findings of the third Russian conference on the MPC+A with a specific emphasis on physical protection of the Russian nuclear materials and nuclear facilities. Besides the physical protection, materials accounting, education and training of personnel, security culture and some other associated topics of the conference are also addressed. (author)

    In nuclear related field, there are three different cultures: safety, safeguards and security culture. Safety culture has established mostly in nuclear industries, meanwhile safeguards and security culture are relatively new and still developing. The latter is intended to improve the physical protection of material and nuclear facility. This paper describes concept, properties and factors affecting security culture and interactions among these cultures. The analysis indicates that anybody involving in nuclear material and facility should have strong commitment and awareness of such culture to establish it. It is concluded that the assessment of security culture outlined in this paper is still preliminary for developing and conduction rigorous security culture implemented in a much more complex facility such as nuclear power plant

    In the late 1950s, the Westinghouse Electric Corporation undertook a nuclear materials control study for the Division of International Affairs of the US Atomic Energy Commission (AEC). The objective of the study was to develop a Nuclear Materials Control System (NMCS) that could be used under the US bilateral agreements or by the International Atomic Energy Agency. Phase I was a system study to determine the requirements for an NMCS for an assumed nuclear fuel complex. This paper summarizes aspects of Phase I studies addressing facility types, measurement points, and instrumentation needs and Phase II studies covering chemistry/chemical engineering, nuclear, special devices, and security devices and techniques. 1 fig

  19. An accountancy system for nuclear materials control in research centres

    1979-01-01

    The Nuclear Accountancy and Control System (NACS) was developed at KFA Juelich in accordance with the requirements of the Non-Proliferation Treaty. The main features are (1) recording of nuclear material in inventory items. These are combined to form batches wherever suitable; (2) extrapolation of accounting data as a replacement for detailed measurement of inventory items data. Recording and control of nuclear material are carried out on two levels with access to a common data bank. The lower level deals with nuclear materials handling plus internal management while on the upper level there is a central control point which is responsible for nuclear safeguarding within the entire research centre. By keeping the organizational and technical infrastructure it was possible to develop a system which is both economical and operator-oriented. In this system the emphasis of nuclear safeguarding is placed on the acquisition of the nuclear material inventory. As much consideration has been given to the interests of the various operational levels and organizational units as to internal and national regulations. Since it is part of the safeguarding and control system, access to the NACS must be restricted to a limited number of users only. Furthermore, it must include facilities for manual control in the form of records. Authorization for access must correspond with the various tasks of different user groups. All necessary data are acquired decentrally in the organizational units and entered via a terminal. It is available to the user groups on both levels through a central data bank. To meet all requirements, the NACS has been designed as an integrated, computer-assisted information system for the automated processing of extensive and multi-level nuclear materials data. As part of the preventive measures entailed with nuclear safeguarding, the accountancy system enables the operator of a nuclear plant to furnish proof of non-diversion of nuclear material. (author)

  20. Physical protection concepts of nuclear materials. The French experience

    1995-01-01

    As the nuclear energy was being developed, it appeared necessary to set up protections against its potential hazards, that should be more complete and elaborate than those implemented on the other industrial installations. This had to be done both in the safety field to prevent the environment and the populations from the consequences of severe casualties, and in the security field to avoid the risk of proliferation and limit to an acceptable level the results of voluntarily provoked accidents and sabotages. Taking advantage of the gathered experience, this document gives consideration to the concepts used in France in order to ensure the physical protection of the nuclear materials. The following topics are tackled: context inside which are envisaged the specific measures, coherence with the general dispositions taken to protect industrial installations, importance and limitations of the part played by the regulations, respective responsibilities of the plant operators and the public authorities, compromise between objectives in view and means to implement, adjustment between the physical protection system and the operating requirements. In addition, the ways in which these systems should be implemented are discussed, underlining the necessity to make progressive steps under a permanent will, in order, first, to update and bring under conformity the old installations, and second, to ensure the maintenance of the systems, taking account of the evolutions of needs and techniques. Those points are commented on examples taken among the different types of installations to be found in France, showing the differences in approach coming from the type and the age of the facilities, and giving the present trends for the new plants.

    State Office for Nuclear Safety (SONS) is established based on 'Nuclear Safety Act' (Official Gazette No. 173/2003) as an independent state organization responsible for all questions in connection with safe use of nuclear energy and technology, for expert matters of preparedness in the case of nuclear emergency, as well as for international co-operation in these fields (regulatory body). In the second half of year 2006, stationary detection systems for nuclear and other radioactive materials were installed on Border Crossing Bregana, Croatia. Yantar 2U, which is the commercial name of the system, is integrated automatic system capable of detection of nuclear and other radioactive materials prepared for fixed-site customs applications (Russian origin). Installed system contains portal monitors, camera, communication lines and communication boxes and server. Two fully functional separate systems has been installed on BC Bregana, one on truck entrance and another one on car entrance. In this article the operational experience of installed system is presented. This includes statistical analysis of recorded alarms, evaluation of procedures for operational stuff and maintenance and typical malfunction experience, as well as some of the recommendation for future use of detection systems. Ordinance on the control of nuclear material and special equipment (Official Gazette No. 15/08) lays down the list of nuclear materials and special equipment as well as the list of other activities related to the production of special equipment and non-nuclear materials; the contents of the declaration of intent form for export/import of goods, the form for notifying export/import of goods, the form for notifying transport of nuclear material, the form for notifying the activity related to producing of special equipment and non-nuclear material, as well as of the form of the report on nuclear material balance in the user's material balance area.

    A nuclear material control and accountability (MC and A) system effectiveness tool (MSET) has been developed in the United States for use in evaluating material protection, control, and accountability (MPC and A) systems in nuclear facilities. The project was commissioned by the National Nuclear Security Administration's Office of International Material Protection and Cooperation. MSET was developed by personnel with experience spanning more than six decades in both the U.S. and international nuclear programs and with experience in probabilistic risk assessment (PRA) in the nuclear power industry. MSET offers significant potential benefits for improving nuclear safeguards and security in any nation with a nuclear program. MSET provides a design basis for developing an MC and A system at a nuclear facility that functions to protect against insider theft or diversion of nuclear materials. MSET analyzes the system and identifies several risk importance factors that show where sustainability is essential for optimal performance and where performance degradation has the greatest impact on total system risk. MSET contains five major components: (1) A functional model that shows how to design, build, implement, and operate a robust nuclear MC and A system (2) A fault tree of the operating MC and A system that adapts PRA methodology to analyze system effectiveness and give a relative risk of failure assessment of the system (3) A questionnaire used to document the facility's current MPC and A system (provides data to evaluate the quality of the system and the level of performance of each basic task performed throughout the material balance area (MBA)) (4) A formal process of applying expert judgment to convert the facility questionnaire data into numeric values representing the performance level of each basic event for use in the fault tree risk assessment calculations (5) PRA software that performs the fault tree risk assessment calculations and produces risk importance

    Nuclear Material Accounting and Control (NUMAC) represents one of the most important and indispensable responsibilities of any nuclear installation. The emphasis is to ensure that the nuclear material being handled in the nuclear installation is properly accounted for with the expected accuracy and confidence levels. A number of analytical methods based on both destructive and non-destructive assay techniques are available at the disposal of the nuclear analytical scientists for this purpose and they have been enumerated extensively in literature. Instead of recounting the analytical methodologies available, an attempt has been made in this paper to highlight some of the challenges. (author)

    Full text: It is a matter of common knowledge, that the responsibility for establishing and operating a comprehensive physical protection system for nuclear material and facilities within a state shall rest entirely with the Government of that state. In Belarus all nuclear materials, including HEU, are located at the Center of Nuclear Technologies of the Belarus National Academy of Sciences 'Sosny'. Through regulatory resolution on measures for physical protection of nuclear materials issued by the Council of Ministers of the Republic of Belarus in 1993, the committee for Supervision of Industrial and Nuclear Safety (Promatomnadzor) was appointed as the authority responsible for ensuring physical protection of nuclear materials and facilities and was tasked to develop and approve relevant normative documents. In 1994 Promatomnadzor issued the order on ensuring physical protection of nuclear materials during use, storage and transportation that was in line with then relevant IAEA recommendations. Since September 2001 Promatomnadzor has been a department of the Ministry for Emergencies of the Republic of Belarus. The system of physical protection at 'Sosny' includes elements of the 'old' system set up in 1984, and the 'new' one installed in 1996 as a result of a multilateral co-operative effort between Belarus, Sweden, Japan and USA. The main technical components of the system are: detection system including magnetic, microwave and infrared sensors; video-surveillance system; system of access delay including electronic blocking devices; system of authorized access including magnetic cards; system of computerized control over all components and communication system. Discussions between potential donor states are taking place regarding various security upgrades, particularly to the protected area where main security sensitive buildings are located. In 2000 Promatomnadzor requested an international physical protection advisory service (IPPAS) mission from the IAEA. The

    Full text: Since the 9.11 terror, strengthening physical protection has been an accelerated trend internationally. IAEA has been requesting that member states implement a strengthened physical protection of nuclear facilities on the basis of threat assessments. In order to cope with this demand, the Korean government promulgated the 'Law for Physical Protection and Radiological Emergency Preparedness (LPPRE)' as a substantial countermeasure against possible threats. Pursuant to LPPRE, which entered into force on February 16, 2004, nuclear enterprisers are obliged to implement an effective physical protection of nuclear materials, get approval for its physical protection system, and be constantly inspected on. The Ministry of Science and Technology (MOST) approved physical protection regulations of 24 domestic facilities operated by 14 enterprisers. National Nuclear management and Control Agency (NNCA) is entrusted with physical protection related duty and has been conducting physical protection inspection on nuclear materials in use, storage and transport. In addition, NNCA has established the methodology of threat assessment that entails organizing the threat assessment working group to develop a design basis threat (DBT). Korea is putting its best efforts to construct the threat assessment system and strengthen domestic physical protection regime in cooperation with competent authorities. (author)

    Full text: The problem of protecting sensitive fissile and fissionable nuclear materials of misuses by governments has been the subject of the convention on physical protection of nuclear material (CPPNM), which entered into force on February 8, 1987. However, in May 2001 the final report of the expert meeting had already recognized 'a clear need to strengthen the international physical protection regime'. The board of governors of the International Atomic Energy Agency (IAEA) decided then to convene a group, which would meet in Vienna from 3 to 7 December 2001, to draft on amendment to the CPPNM. The tragic occurrences of September 11, 2001, however, changed the then generally accepted view on the problem of physical protection, because nuclear materials had to be protected from falling into the hands of terrorists rather than of governments thirst of nuclear sensitive materials. Moreover, crude explosive devices could be made by terrorists, or hired scientists, using readily available radioactive materials, like 226 Ra or 137 Cs to inflict damage to civilians. Thus physical protection of those and other radioactive materials became an instant challenge for national and international authorities to prevent the use of such materials in terrorist actions. The prevention of illicit trafficking of radioactive materials is now in the priority list of these authorities. Fortunately; an international conference on 'Measures to Detect, Intercept and Respond to the Illicit Uses of Nuclear Materials and Radioactive Sources' was held in Stockholm, Sweden, in May 2001. An IAEA document - GOV/2001/37-GC(45)/20 - recommended in its plan of activities a series of projects to be implemented between 2002 and 2005, which included developing and providing assistance for the application of: (i) standards for physical protection of nuclear materials and nuclear facilities in member states; (ii) norms and guidelines for nuclear material accounting and control in member states; (iii

  11. Use of Nuclear Material Accounting and Control for Nuclear Security Purposes at Facilities. Implementing Guide

    International Nuclear Information System (INIS)

    2015-01-01

    Nuclear material accounting and control (NMAC) works in a complementary fashion with the international safeguards programme and physical protection systems to help prevent, deter or detect the unauthorized acquisition and use of nuclear materials. These three methodologies are employed by Member States to defend against external threats, internal threats and both state actors and non-state actors. This publication offers guidance for implementing NMAC measures for nuclear security at the nuclear facility level. It focuses on measures to mitigate the risk posed by insider threats and describes elements of a programme that can be implemented at a nuclear facility in coordination with the physical protection system for the purpose of deterring and detecting unauthorized removal of nuclear material

    2001-01-01

    Full text: The signature of Peru to become part of the Convention of Physical Protection of Nuclear Material in 1995 has implied an obligation to formalize the legal and regulatory infrastructure for this purpose. As first step, physical protection measures were formalized on the two nuclear facilities: one critical assembly of zero power (RP0) and another research reactor of 10 Mw thermal power (RP10). Both of the installations use low enriched uranium nuclear fuel (Material and Testing Material - MTR type). On the other side, even thorium was put in perspective to control; currently it is being used for non-nuclear purposes and has not been included inside the physical protection measures. Its physical and chemical form and its small quantity do not warrant for applying the Convention. The physical protection measures implemented in the research reactor are well depicted and it is concluded that the physical protection system meets the recommendations of INFCIRC/225/Rev.3. The critical facility (RP0), as having nuclear material categorized III, has implemented a less restrictive system but enough to meet the requirements. In 1999 an evaluation of all physical protection systems was performed for these two nuclear installations. This evaluation took into account the recommendations of INFCIRC/225/Rev.4. The general conclusion was that the performance of physical protection system was suitable to the categories of nuclear material - II and III - and that the installations where nuclear material is used were suitably protected against non-authorized or illegal removal of nuclear material and sabotage. However, some of components of the system were not appropriately working and could make all of the system weak. Another of the identified problems was the lack of a rule on physical protection and also the lack of the Design Basis Threat, although this fact was well known due the social conditions in the country. The second undertaking has been to prepare the rule on

    Now, very safe and stable supply of electric power has become to be obtained by nuclear energy, and Japan has steadily promoted nuclear power as the basic energy that contributes to overcome the unstable structure of energy supply in Japan highly depending on foreign countries, as shown in the long term plan of the research, development and utilization of nuclear power. Great progress was observed in nuclear fuel recycling in Japan such as the attainment of initial criticality of the prototype FBR 'Monju' and the start of construction of the commercial fuel reprocessing plant in Rokkasho. Recently the recognition of the importance of nuclear substance management has heightened, and the measures for maintaining and strengthening the reliability of nuclear nonproliferation system are investigated. It is important that Japan strictly observes the nuclear nonproliferation system based on the NPT which was extended infinitely. In this handbook, the outline of the measures for nuclear nonproliferation and safeguard and the protection of nuclear substances, the treaties and agreements and the national laws related to these are described.

    objective is timely prevention, detection of and response to the attempts to use accounted nuclear material for illicit trafficking. In addition to traditional measures, a centralized automated system to detect unauthorized intrusion, to register and suppress the penetration attempts and to organize controlled access to nuclear installation Chernobyl NPP and its internal areas is being established. This system covers three levels of hierarchical physical protection system of all facilities of Chernobyl NPP. The distinguishing features of this system are: high level of stability and reliability, automatic self-diagnostic functions, detection of performance intrusion and restoration of the normal operability. This system has a number of local physical protection subsystems which are the key data base users and are capable to operate off-line in case of the short-time loss of connection with the top level. The access means will include full-height turnstiles and tripods. In the areas of particular importance video identification is envisaged. Passive remote inductive cards encoded on-site will be used as passes. In addition, the issue of control, accountancy and physical protection to be exercised throughout the whole process of fuel discharge, cooling and transportation to KHOYAT -2 (interim storage facility), which will house nuclear material of the total activity more than 1.2 million Ci and about 4.00 tonnes Pu-239, is under review. It is envisaged to create complex to support nuclear material management processes. A provisional engineering solution provides for visual control and video recording, automated record of processes, casks' integrity control, communication means, blocking of the further operations when the precedent operations are inconsistent with QA program requirements, routing control and response forces notification. It shall be emphasized that so far we do not know for sure the amount of nuclear and radioactive materials inside the Shelter Object which is

    Full text: The Brazilian Nuclear Energy Commission is the national licensing authority and among its responsibilities is the control of nuclear materials and radiation sources. This control is carried out in three different ways: 1) Control of the import and export of nuclear materials and radiation sources. To be able to import or export any nuclear material or radiation source, the user has to have an explicit permission of the licensing authority. This is controlled by electronic means in which the user has to fill a special form found on the licensing authority's home page, where he has to fill in his name, license number, license number of his radiation protection officer and data of the material to be imported or exported. These data are checked with a data base that contains all the information of the licensed users and qualified personnel before authorization is emitted. The airport authorities have already installed x-ray machines to check all baggages entering or leaving the country. 2) Transport and transfer permit for radiation sources. In order to transport and/or transfer radiations sources and nuclear materials within the country, the user(s) have to submit an application to the licensing authority. The user(s) fill out an application form where he fills in his company's name, licensing I.D., radiation protection officer's name and I.D and identification of the sources involved. These information are checked with the licensing operations data before the operations is permitted. 3) Inspections and radiation monitoring systems. Routine and regulatory inspections are continuously carried out where the user's radiation sources and nuclear materials inventory are checked. Also the physical security and protection of these materials are verified. The installation of monitoring systems is an item that is being discussed with the airport authorities so as to increase the possibilities of detecting any illegal transport of these materials.

    1997-09-01

    The Physical Protection of Nuclear Material, INFCIRC/225/Rev.3, provides recommendations for the physical protection of nuclear material against theft in use, storage and transport, whether national or international and whether peaceful or military, and contains provisions relating to the sabotage of nuclear material or facilities. The recommendations contained in INFCIRC/225/Rev.3 detail the elements that should be included in a State's system of physical protection. It also recognizes the adverse health and safety consequences arising from the theft of nuclear material and the sabotage of nuclear material or facilities. Most industrial and developing countries use these recommendations to some extent in the establishment and operation of their physical protection systems. Although INFCIRC/225/Rev.3 provides recommendations for protecting materials and facilities from theft or sabotage, it does not provide in-depth details for these recommendations. In June 1996, the IAEA convened a consultants meeting to consider this matter. This report is the result of continuing discussions and drafts over a period of nine months. The intent of this guidance is to provide a broader basis for relevant State organizations to prescribe appropriate requirements for the use of nuclear materials which are compatible with accepted international practice

    A significant portion of the Los Alamos Scientific Laboratory Safeguards Program is directed toward the development and demonstration of dynamic nuclear materials control. The building chosen for the demonstration system is the new Plutonium Processing Facility in Los Alamos, which houses such operations as metal-to-oxide conversion, fuel pellet fabrication, and scrap recovery. A DYnamic MAterials Control (DYMAC) system is currently being installed in the facility as an integral part of the processing operation. DYMAC is structured around interlocking unit-process accounting areas. It relies heavily on nondestructive assay measurements made in the process line to draw dynamic material balances in near real time. In conjunction with the nondestructive assay instrumentation, process operators use interactive terminals to transmit additional accounting and process information to a dedicated computer. The computer verifies and organizes the incoming data, immediately updates the inventory records, monitors material in transit using elapsed time, and alerts the Nuclear Materials Officer in the event that material balances exceed the predetermined action limits. DYMAC is part of the United States safeguards system under control of the facility operator. Because of its advanced features, the system will present a new set of inspection conditions to the IAEA, whose response is the subject of a study being sponsored by the US-IAEA Technical Assistance Program. The central issue is how the IAEA can use the increased capabilities of such a system and still maintain independent verification

  4. Physical protection of special nuclear materials in the Federal Republic of Germany

    1987-01-01

    Measures to protect special nuclear materials in West Germany are based on a relatively likely average threat and not on the less-likely but maximum credible threat. The reason is to avoid the costs of maintaining a very high level of security that is seldom needed. The concept of delayed action, which divides the responsibility for security between private protection forces and local police forces, would be insufficient in the event of the maximum credible threat. In principle, sufficient security is possible only when the facilities and transports are constantly protected by a police force large enough to deal with the maximum credible threat without assistance from outside. They must also be adequately armed to avert all possible attackers, and they must be paid by the licensees. The threat of an insider(s) diverting special nuclear material can be addressed only by strengthening the scope and depth of the checks on applicants and employees and the permanent work controls. It is recognized, however, that such security measures may not be compatible with constitutional civil liberties

    Special nuclear materials must be protected against the threat of diversion or theft, and nuclear facilities against the threat of industrial sabotage. Implicit in this protection is the means of controlling access to protected areas, material access areas, and vital areas. With the advent of automated personal identification technology, the processes of access control can be automated to yield both higher security and reduced costs. This paper first surveys the conventional methods of access control; next, automated personal identification concepts are presented and various systems approaches are highlighted; finally, Calspan's FINGERSCAN /sub TM/ system for identity verification is described

    The implementation of safeguards agreements has always involved governmental organizations to a greater or lesser extent, according to the practices of the State concerned. When the Safeguards Committee 1970 defined the structure and content of agreements required in connection with the Treaty on the Non-Proliferation of Nuclear Weapons, particular attention was paid to the contacts between States and the Agency during the implementation of such agreements. The basic idea was that in each State a national organization would, as far as possible, lay the foundations for international safeguards. Accordingly, NPT safeguards agreements contain the obligation of the State to establish and maintain a 'State's system of accountancy for and control of nuclear material'. The Agency document describing the structure and content of NPT safeguards agreements, INFCIRC/153, also known as the 'Blue Book', lays down the basic requirements for a State's system of accounting for and control of nuclear material - SSAC for short. The same document stipulates that the Agency in its safeguards work should take due account of the technical effectiveness of the SSAC. In practice, the effectiveness of SSACs may differ widely. To take due account of their effectiveness, the Agency has to analyse them, note the elements included in them and the requirements they meet, and consider the particular situations they are designed to cope with

    An overview of performance testing as used at U.S. Department of Energy facilities is provided. Performance tests are performed on specific aspects of the regulations or site policy. The key issues in establishing a performance testing program are: identifying what needs to be tested; determining how to test; establishing criteria to evaluate test results. The program elements of performance testing program consist of: planning; coordination; conduct; evaluation. A performance test may be conducted of personnel or equipment. The DOE orders for nuclear material control and accountancy are divided into three functional areas: program administration, material accounting, and material control. Examples performance tests may be conducted on program administration, accounting, measurement and measurement control, inventory, and containment [ru

    The aim of this project is to establish a rigid foundation of national safeguards and to develop the new technologies for the nuclear control. This project is composed of four different technologies; 1. Monitoring technology for nuclear materials, 2. Detection technology for a single particle, 3. Safeguards information management technology, 4. Physical protection technology. Various studies such as a remote verification system for CANDU spent fuel in dry storage canister, a spent fuel verification system using an optical fiber scintillator, and development of softwares for safeguards and physical protection were performed in the frist phase('99-'01). As a result of this research, it has been identified that the developed technologies could be a crucial means of the control for the nuclear material and facilities related. We are planing to accomplish a steady national safeguard system in the second phase('02-'06). This research will help to elevate the transparency and credibility in national nuclear activities by improving the relative technologies

    The support programs for Republic of Kazakstan have been carried out for the purpose of establishing the State System of Accounting for and Control of Nuclear Material (SSAC). These support are based on the cooperation agreement for the elimination of nuclear weapons, that reached mutual agreement between both government of Japan and the Republic of Kazakstan in March, 1994, 1994. Japan, Sweden, the United Kingdom and the United States of America have conducted the support for Kazakstan. Since there are many facilities to be supported such as fast reactors, fuel fabrication facilities and research facilities, items to be supported are coordinated and shared among the supporting countries. Japan has been carrying out the supporting tasks mainly for the fast breeder reactor facility, BN-350 and Atomic Energy Agency of Kazakstan (KAEA). PESCO Co., Ltd. is entrusted this supporting work from Technical Secretariat on Cooperation for the Elimination of Nuclear Weapons Reduced in the Former Soviet Union, and has conducted the support in the area of flow monitoring system, nuclear material accounting and control and physical protection, obtaining technical cooperation from Power Reactor and Nuclear Development Corporation (PNC)

    The Department of Energy (D.O.E.) is responsible for the long term storage and protection of large quantities of Special Nuclear Material (SNM). This material is stored within individual containers located in vaults. Security measures are required to ensure that the SNM remains within the canisters where it is stored and that it is not disturbed in any manner. Conventional security and inventory techniques are manpower intensive and often require exposure to radiation hazards. The Purpose of this D.O.E sponsored project is to develop a cost effective system to monitor Special Nuclear Materials that, when fielded, would result in an extension of manual inventory cycles at a wide variety of SNM storage locations. The system consists of a computer, radio frequency interrogator, and individual miniaturized radio frequency transponders (tags) that are co-located with individual SNM containers. Each tag can perform SNM inventory, tamper alarm, and multiple sensor data transmission to the interrogator under the control of software designed by the user. SNM custodians can customize the system by their choice of packaging, software, and sensors. When implemented in accordance with current department of energy (D.O.E.) Policy on SNM inventory extension, the system has the potential to qualify for maximum extension times thus saving considerable resources through reduction of radiation exposure

    The Convention on the Physical Protection of Nuclear Material was signed in Vienna, on April 3, 1980, approved by Law 23.620 on September 28, 1998, and published in the Official Bulletin of the Argentine Republic on November 2, 1988. This Convention considers some aspects of Criminal Law and Criminal Procedural Law and integrates the normative hierarchical structure of the article 31 of the National Constitution. The adequacy of this Convention to the Argentine law is considered through two aspects: The first one examines figures existing in the Argentine Legislation about larceny and robbery of nuclear materials, misappropriation of nuclear materials, obtainment and fraud of nuclear materials, exaction through threat or intimidation, etc., which are considered in different articles of the Argentine Criminal Law. The second one analyses behaviours not foreseen in the Criminal Law and which are not qualified by the current Argentina's Criminal Code, such as exaction of nuclear material through the use of violence, the international perpetration of an act consisting to receive, possess, use, vacate, scatter nuclear material without legal authorization, or in the case that the act causes death, serious injuries to persons and others. The purpose of the future enactment of a new Nuclear Law is to put in order and fill-in gaps referred to different aspects such as civil liability in nuclear damages, characteristics of the nuclear damages, etc [es

    The french approach for considering malevolent actions affecting the design and operation of nuclear facilities is aimed at determining the extent to which the facilities are protected. When carrying out these studies, operating organizations have to demonstrate that their are complying with the objectives set by the Competent Authority for reducing the risk of internal or external malevolent actions. The approach to be followed consist to determine the sensitivity of each zone and to estimate the vulnerability of the most critical zones to each type of aggression. The sensitivity can be defined by the level of the radiological consequences resulting from a malevolent action. The estimation of the vulnerability is made of the extent to which it is difficult to carry out a malevolent action. if need be, counter-measures are taken to protect zones for which the consequences would be unacceptable compared to the force of the aggression. Counter-measures are intended both to minimise sensitivity and make it more difficult to carry out the aggression envisaged. Acceptable consequences are taken as being those leading to levels of radioactive releases less than, or equal to, those taken into account in the facility safety case. This implies that the vulnerability of the most sensitive zones should be reduced to a minimum so that an acceptable level of protection can be provided for these areas. Emphasis will be paid on the defence in depth approach organized around prevention, management and mitigation measures. (authors)

    2002-01-01

    The State System of Accounting for and Control of Nuclear Material (SSAC) is based on requirements resulting from the Safeguards Agreement between the Government of the Slovak Republic and the IAEA. UJD performs this activity according to the 'Atomic Act' and relevant decree. The purpose of the SSAC is also to prevent unauthorised use of nuclear materials, to detect loses of nuclear materials and provide information that could lead to the recovery of missing material. The main part of nuclear materials under jurisdiction of the Slovak Republic is located at NPP Jaslovske Bohunice, NPP Mochovce and at interim storage in Jaslovske Bohunice. Even though that there are located more then 99% of nuclear materials in these nuclear facilities, there are not any significant problems with their accountancy and control due to very simply identification of accountancy units - fuel assemblies, and due to stability of legal subjects responsible for operation and for keeping of information continuity, which is necessary for fulfilling requirements of the Agreement. The nuclear material located outside nuclear facilities is a special category. There are 81 such subjects of different types and orientations on the territory of the Slovak Republic. These subjects use mainly depleted uranium as a shielding and small quantity of natural uranium, low enrichment uranium and thorium for experimental purposes and education. Frequent changes of these subjects, their transformations into the other subjects, extinction and very high fluctuation of employees causes loss of information about nuclear materials and creates problems with fulfilling requirements resulting from the Agreement. In 2001, the UJD carried out 51 inspections of nuclear materials, of which 31 inspections were performed at nuclear installations in co-operation with the IAEA inspectors. No discrepancies concerning the management of nuclear materials were found out during inspections and safeguards goals in year 2001 were

    Networking- and distributed-processing hardware and software have the potential of greatly enhancing nuclear materials control and accountability (MC and A) systems, from both safeguards and process operations perspectives, while allowing timely integrated safeguards activities and enhanced computer security at reasonable cost. A hierarchical distributed system is proposed consisting of groups of terminal and instruments in plant production and support areas connected to microprocessors that are connected to either larger microprocessors or minicomputers. These micros and/or minis are connected to a main machine, which might be either a mainframe or a super minicomputer. Data acquisition, preliminary input data validation, and transaction processing occur at the lowest level. Transaction buffering, resource sharing, and selected data processing occur at the intermediate level. The host computer maintains overall control of the data base and provides routine safeguards and security reporting and special safeguards analyses. The research described outlines the distribution of MC and A system requirements in the hierarchical system and distributed processing applied to MC and A. Implications of integrated safeguards and computer security concepts for the distributed system design are discussed. 10 refs., 4 figs

    Nuclear energy has been regulated by various international agreements or treaties due to the potential dangers. In case of export or import of nuclear material, it is important to comply with international norms and domestic laws related to nonproliferation and physical protection of nuclear material. Because, if non-compliant, it can be taken nuclear sanctions from the international community, and thus the domestic nuclear activities can be under a negative impact. Recently, international interests in nuclear security have been increased, it has become very sensitive to whether or not to join, and to comply with international treaties during international transportation of nuclear materials. Currently it is not discussed yet how to present and interpret the relevant provisions in CPPNM. However, it is necessary to prepare for the dispute among the parties that we don't know when it happens.

Unfortunately, besides economical communication, the rout can be used for illegal transit of nuclear materials. There is special concern regarding uncontrolled territories of conflict zones. Taking into consideration recent terrible terrorist acts we feel great responsibility for ensuring safety of this rout, which is a precondition of economical development and political stability of the whole Caucasian region A potentially hazardous radiological situation developed in Georgia with orphan radiation sources in the late 1990s and 2001: discovery of high-activity strong Radiation sources of (Strontium-90 from thermo-generators) in Tsalenjikha district. Eight such generators were brought to Georgia in 1984, and four of them have been found in Svanety mountainous region in addition to the two found in the Tsalenjikha, but remaining two are not yet found. During the last years several incidents of illicit trafficking were reported. The radiation problems greatly relate to the withdrawal of the Russian military bases. The radiological accident took place in Lilo, Georgia, when sealed radiation sources had been abandoned by a previous owner at a site. Taking into account the geopolitical location of Georgia it is quite important to strengthen the physical protection infrastructure in country with has serious territorial problems. The first step was to provide an appropriate legal framework for the safety management in the country and clearly identify regulatory body. The ministry implements state control in the nuclear and radiation safety field for protection of environment and natural resources of Georgia (hereinafter referred to as the Ministry). The Ministry is obliged to supervise the physical protection systems. The Ministry shall co-ordinate the state system of physical protection of the use

    Most sensitive nuclear materials are usually shipped in specific vehicles with a reinforced protection; such vehicles are generally escorted, tracked and watched over from a distant control centre. Among the various publications made by the IAEA in relation with the CPPNM, the INFCIRC/225 introduces major recommendations for physical protection of nuclear materials in general and particularly during transport. For instance, the text recommends - for the terrestrial shipment of most sensitive material - the use of vehicles specially designed to resist attack and equipped with a vehicle disabling device. Applying such a recommendation at a state level requires the intervention of a competent authority; the competent authority defines the framework of a validation process starting with the design of the vehicle and ending with the vehicle protection approval. The validation process needs articulating responsibilities between the three major actors who are: the operator in charge of the design, a technical support body in charge of technical evaluation, and the competent authority who is responsible for the final approval of the protection. This paper focuses on the approval process of reinforced protection vehicles in France; it aims at showing how such a process may contribute to the security of nuclear material shipments. The paper notably focuses on the responsibilities of the operators, the competent authority and the technical support organization. This approval process of the protection of a vehicle allows the authority to ensure that the protection setup is effective and operational in order to protect the cargo from a malicious threat. In such a process, the authority defines the threat and the objectives of protection; the authority may choose, in certain case, to recommend protection devices or solutions; the need for recommendation versus objective definition mostly depends on the environment of the vehicle and the constraints induced. The authority may

    The importance of physical protection for nuclear materials and facilities that can be an objective for terrorists has never been more stressed. The responsibility for physical protection within a State does not rest entirely with that state because cross-border transactions related to nuclear materials increase as nuclear related industries expand. The international community has prepared measures to strengthen the regime of physical protection such as the IAEA's proposal of the 'Nuclear Security Plan for 2006-2009' and UN's resolution on 'the International Convention for the Suppression of Acts of Nuclear Terrorism'. In order to cope with this, Korea has also made efforts to establish the implementation system for physical protection in the field of nuclear industries since the law for Physical Protection of Nuclear Material and Facility and Radiological Emergency Preparedness (LPPREP) was promulgated in 2004. The detailed plans should be prepared to accomplish this. This study has been performed to derive the items for establishing the regime of physical protection. The items derived were classified as short, mid and long-term depending on their characteristics and environmental circumstances. The regime of national physical protection will be established if the studies on these items are carried out successfully and tangible results are obtained

    Full text: The physical protection against robbery, diversion of nuclear materials and sabotage of nuclear installations by individuals or groups, has been for long time the reason of national and international concern. Even though, the obligation to create and implement an effective physical protection system for nuclear materials and installations in the territory of a given State, fall entirely on the State's Government, whether this obligation is fulfilled or not, and if it does, in what measure or up to what extent, it also concerns the rest of the States. Therefore, physical protection has become the reason for a regional co-operation. It is evident the need of co-operation in those cases where the physical protection efficiency within the territory of a given State depends also on the appropriate measures other States are taken, specially when dealing with materials been transported through national borders. The above mentioned constitute an important framework for the regional co-operation for the physical protection of nuclear materials. For that reason, the Nuclear Regulatory Authority established criteria and conditions aimed at mitigate diversions, robberies and sabotage to nuclear installations. As a working philosophy, it was established a simplify physical protection model of application in Argentina who, through the ARCAL No. 23 project, will be extrapolated to the whole Latin-American region, concluding that the application of the appropriated physical protection systems at regional level will lead to the strengthening of it at national level.

    The International Conference on Physical Protection 'Strengthening Global Practices for Protecting Nuclear Material' was organized by the Institute of Physics and Biophysics, Salzburg University in cooperation with/supported by the European Commission, Lawrence Livermore National Laboratory, European Forum of the Stanford University's Institute for International Studies and Austria Institute for European Security. Its purpose was fostering exchange of information on the policy and technical aspects require to ensure the security of nuclear material around the world. There is a general concern that the international community needs to establish effective measures to counter theft, sabotage, and other illicit uses of nuclear fissile and other radioactive materials. The main subjects addressed by this conference were: a) global and local threat development and 'design basis'; b) standards for physical protection (PP), its adequacy and future needs; c) national practices in PP of nuclear materials (how to strengthen national security culture?); d) current R and D in security and detection technologies (identification of focus points for future R and D); e) programmes to aid in training, design, and implementation of physical protection systems (how to improve efficiency and assure sustainability of assistance programmes?).

  13. Proposal for guidelines for the physical protection of nuclear materials, plants and transports in Denmark

    International Nuclear Information System (INIS)

    1978-03-01

    The guidelines are based on recommendations in the IAEA's ''Physical Protection of Nuclear Material,'' INFCIRC/225/rev.1. In accordance with practice in other countries, the guidelines give more detailed requirements for the protection of reactor plants than those given in the IAEA's present recommendations, which put more emphasis on the protection of nuclear materials. The measures to be taken for nuclear plants, or nuclear transports, are proposed made to fit the potential risk that the more closely defined actions imply. It is suggested that the more detailed rules for the scope of the protection of plants or materials should be laid down by the National Agency on the basis of recommendations made by the Inspectorate of Nuclear Installations, which in turn are based on the safety documentation of the plant/material owners. It is further proposed that the National Agency, again on a recommendation from the Inspectorate, should lay down more detailed guidelines for the reporting of changes in stocks or transports of nuclear materials.

    The presence of nuclear materials at any nuclear facility must be in secure and must be known as safeguards purpose such as its position, from or type and amount. The clarification of the amount be reported to the national regulatory body and International Atomic Energy Agency (IAEA) as the International regulatory body. The national regulatory body and IAEA will then verify that report. The verification must be done to know there is no difference of the amount, and to give the assurance to the International community that any diversion of safeguarded nuclear material from civil use to a prescribed military purpose would be detected. To carry out verification, several verification techniques such as non-destructive analysis, surveillance, unattended and remote monitoring and environmental sampling are explained to convey the impression how those techniques are implemented. According to the security requirement, the physical protection system including all components of physical protection system have to be effectively designed

    This paper describes the design concept and the current status of an integrated system for nuclear material accountancy and control, which is under development at JAERI. We, at JAERI, have decided to update the current system for material accountancy and control and to develop the integrated new system with a consolidated data base in order to augment transparency, credibility and promptness of the system, to materialize a prudent control of obligations required by bilateral nuclear cooperation agreements, and to give information for the physical protection, safely handling, property control and cost-effective use of nuclear material and for public relations. The system is composed of two work-stations operated by UNIX, one for implementation and the other for development, and many terminals located at the headquarters, administrative offices, and research facilities and laboratories. It is connected with a mainframe computer. There are many files on the data base to record inventory changes, book and physical inventories, and statistics on material balances. These files are controlled by a commercial data base management system which enables us to make access to data on the files with a simple query language, spread sheet type software or an application program.

    2009-01-01

    Small Quantity Nuclear Material (SQNM) is defined as the nuclear material that is below the amount approved in atomic energy act. SQNM generally lists depleted uranium (DU) used as a catalyst or shielding material in exposure devices in industries. The SQNM users have a duty to report information on possessing and using SQNM regularly to the government. All nuclear materials must be included in IAEA reporting lists according to safeguards agreement and additional protocol regardless of amount. However, it is difficult to investigate the status of nuclear material possessed in industries because SQNM is excepted regulation item list in atomic energy act. Most SQNM user industries are small companies so they have some problems like the loss of nuclear material after bankruptcy. Even though the damage of radiation leakage is very low, loss or careless management of nuclear material causes confusion. Thus, developing a control and management system for SQNM is essential. This paper discusses the present condition and prospect of control and management SQNM in Korea

    One of the fundamental regulations of the Russian State System for Nuclear Material Accounting and Control (SSAC), ''Basic Nuclear Material Control and Accounting Rules,'' directed that a uniform report system be developed to support the operation of the SSAC. According to the ''Regulation on State Nuclear Material Control and Accounting,'' adopted by the Russian Federation Government, Minatom of Russia is response for the development and adoption of report forms, as well as the reporting procedure and schedule. The report forms are being developed in tandem with the creation of an automated national nuclear material control and accounting system, the Federal Information System (FIS). The forms are in different stages of development and implementation. The first report forms (the Summarized Inventory Listing (SIL), Summarized Inventory Change Report (SICR) and federal and agency registers of nuclear material) have already been created and implemented. The second set of reports (nuclear material movement reports and the special anomaly report) is currently in development. A third set of reports (reports on import/export operations, and foreign nuclear material temporarily located in the Russian Federation) is still in the conceptual stage. To facilitate the development of a unified document system, the FIS must establish a uniform philosophy for the reporting system and determine the requirements for each reporting level, adhering to the following principles: completeness--the unified report system provides the entire range of information that the FIS requires to perform SSAC tasks; requisite level of detail; hierarchical structure--each report is based on the information provided in a lower-level report and is the source of information for reports at the next highest level; consistency checking--reports can be checked against other reports. A similar philosophy should eliminate redundancy in the different reports, support a uniform approach to the contents of

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international cooperation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and materials, particularly when such materials are transported across national frontiers [French] La proteccion fisica contra el robo o la desviacion no autorizada de materiales nucleares y contra el sabotaje de las instalaciones nucleares por parte de individuos o de grupos ha sido durante largo tiempo motivo de preocupacion nacional e internacional. Aunque la obligacion de crear y hacer funcionar un sistema completo de proteccion fisica para las instalaciones y materiales nucleares en el territorio de un Estado determinado incumbe enteramente al Gobierno de dicho Estado, el que esa obligacion se cumpla o no, y si se cumple, en que medida o hasta que punto, es cosa que no deja indiferentes a los demas Estados. De aqui que la proteccion fisica se haya convertido en motivo de interes y cooperacion internacional. La necesidad de cooperacion internacional se hace evidente en los casos en que la eficacia de la proteccion fisica en el territorio de un Estado depende de que otros Estados tomen tambien medidas apropiadas para evitar o hacer fracasar los actos hostiles dirigidos contra instalaciones y

    Under the Situation and Crisis Center (SCC) management, the Information Analytical Center (IAC) of the Ministry of Atomic Energy (Minatom) of Russia was created to oversee the operation of the Federal Nuclear Material Control and Accounting Information System (FIS). During 2000, the FIS achieved an important milestone in its development: the basic functions of the information system were implemented. This includes placing into operation the collecting and processing of nuclear material control and accounting (MC and A) information from the enterprises reporting to the FIS. The FIS began working with 14 Russian enterprises to develop and implement full-function reporting (i.e., reporting inventory and inventory changes including closeout and reconciliation between the FIS and enterprises). In 2001, the system will expand to include enterprise-level inventory information for all enterprises using nuclear materials in Russia. For this reason, at the end of 2000 through the beginning of 2001, five separate training sessions were held for over 100 enterprise personnel responsible for preparation and transfer of the reports to the FIS. Through the assistance of the Nuclear Material Protection, Control and Accounting (MPC and A) program, information systems for the accounting of nuclear materials are being installed at Russia enterprises. In creating the program for modernization of the Russian Federation State System of Accounting and Control (SSAC) of nuclear material, the SCC conducted a survey of the enterprises to determine the readiness of their internal MC and A systems for reporting to the FIS. Based on the information from the survey and the results of the projects on creation of local information systems at Russian enterprises, the analysis of information and the technical aspects of MC and A systems identified deficiencies that were analyzed and recommendations for eliminating these deficiencies were proposed.

    Forcella, A.A.; O'Leary, W.J.

    1966-01-01

    This paper describes the scope of nuclear materials management for a typical power reactor in the United States of America. Since this power reactor is financed by private capital, one of the principal obligations of the reactor operator is to ensure that the investment is protected and will furnish an adequate financial return. Because of the high intrinsic value of nuclear materials, appropriate security and accountability must be continually exercised to minimize losses beyond security and accountability for the nuclear materials. Intelligent forethought and planning must be employed to ensure that additional capital is not lost as avoidable additional costs or loss of revenue in a number of areas. The nuclear materials manager must therefore provide in advance against the following contingencies and maintain constant control or liaison against deviations from planning during (a) pre-reactor acquisition of fuel and fuel elements, (b) in-reactor utilization of the fuel elements, and (c) post-reactor recovery of fuel values. During pre-reactor planning and operations, it is important that the fuel element be designed for economy in manufacture, handling, shipping, and replaceability. The time schedule for manufacturing operations must minimize losses of revenue from unproductive dead storage of high cost materials. For in-reactor operations, the maximum achievable burn-up of the fissionable material must be obtained by means of appropriate fuel rearrangement schemes. Concurrently the unproductive down-time of the reactor for fuel rearrangement, inspections, and the like must be minimized. In the post-reactor period, when the fuel has reached a predetermined depletion of fissionable material, the nuclear materials manager must provide for the most economical reprocessing and recovery of fissionable values and by-products. Nuclear materials management is consequently an essential factor in achieving competitive fuel cycle and unit energy costs with power reactors

    The measurement systems in use at Savannah River Site, SRS, to determine material balance around dissolution of fuel, separation and purification of actinides to a nitrate product are described. To ensure that volume accuracy's are as expected, SRS has implemented a volumetric measurement control program to control errors and to detect anomalies. The program consists of periodic instrument calibrations, comparison of in-tank density measurements. An analytical quality control program is in place at SRS to provide assurance that analysis are reliable and to estimate and monitor method performance. Checks include the analysis of standard prior to the use of each method each shift the method is used. At SRS cumulative inventory difference is compared to the combined errors for the balance. The results from current evaluations for uranium and plutonium balances are presented [ru

    Pike, D.H.; Morrison, G.W.; Westley, G.W.

    1977-10-01

    The feasibility of using modern state estimation techniques (specifically Kalman Filtering and Linear Smoothing) to detect losses of material from material balance areas is evaluated. It is shown that state estimation techniques are not only feasible but in most situations are superior to existing methods of analysis. The various techniques compared include Kalman Filtering, linear smoothing, standard control charts, and average cumulative summation (CUSUM) charts. Analysis results indicated that the standard control chart is the least effective method for detecting regularly occurring losses. An improvement in the detection capability over the standard control chart can be realized by use of the CUSUM chart. Even more sensitivity in the ability to detect losses can be realized by use of the Kalman Filter and the linear smoother. It was found that the error-covariance matrix can be used to establish limits of error for state estimates. It is shown that state estimation techniques represent a feasible and desirable method of theft detection. The technique is usually more sensitive than the CUSUM chart in detecting losses. One kind of loss which is difficult to detect using state estimation techniques is a single isolated loss. State estimation procedures are predicated on dynamic models and are well-suited for detecting losses which occur regularly over several accounting periods. A single isolated loss does not conform to this basic assumption and is more difficult to detect

The system has two major components, inventory files and system parameter files. AIMS, part of the overall safeguards program, maintains an up-to-date record of nuclear material by location, produces reports required by ERDA in addition to onplant reports, and is capable of a wide range of response to changing input/output requirements through use of user-prepared parameter cards, as opposed to basic system reprogramming

  13. Nuclear material control and accounting by process simulation with smalltalk

    International Nuclear Information System (INIS)

    O'Rourke, P.E.; Soper, P.D.

    1986-01-01

    Smalltalk, an object oriented computer language, enables programmers to build data structures and code which explicitly reflect the structure and working of a facility in an easily understood fashion. This paper discusses demonstration material control and accounting system that has been written in Smalltalk for the IBM PC-XT computer using the methods environment from Digitalk, Inc. The system is designed to track uranium through a processing facility. The objects are generic and not specific to any facility, objects like vault positions or tanks are created from classes of objects called uranium accounts. Uranium account objects are connected by a list of transfer rules which should reflect the operation of the facility. If operations or equipment are changed, only those rules or objects which simulate the affected components must be changed. By the nature of Smalltalk code, other objects will not be affected by these changes

    Krivanek, M.; Krtil, J.; Moravec, J.; Pacak, P.; Sus, F.

    1977-01-01

    Central Control Laboratory (CCL) of the Nuclear Research Institute was charged with the control of nuclear materials in CSSR within the framework of the safeguards system. The CCL has been directed by the Department of nuclear safety and safeguards of CAEC according to a long-term plan, elaborated for controlling nuclear material in CSSR. The CCL has mainly been performing independent, rapid, accurate, and reliable analyses of nuclear materials, using destructive as well as non-destructive methods; the analyses of samples taken in MBA's in CSSR are mentioned, concerning the determinations of U, Pu, and Th contents, isotopic compositions of U and Pu, and burn up. The results of the analyses have served for the material and isotopic balances of fissile materials and the control of fuel reprocessing under laboratory conditions. The methods for sampling and sample transport as well as sample treatment before the analysis are described. The experience is given, obtained at CCL during a routine application of chemical methods for highly precise determinations of U, Pu, and Th (titration-based methods), mass-spectrometric determinations of U and Pu (isotopic composition, IDA using 233 U and 242 Pu), and burn-up determinations based on radioactive fissile products (Cs, Ru, Ce) and stable Nd isotopes. Some non-destructive methods for controlling nuclear materials (passive gamma-spectrometry) are discussed

    In processing radioactive material there are certain steps which have customarily required operators working at glove box enclosures. This can subject the operators to low level radiation dosages and the risk of accidental contamination, as well as generate significant radioactive waste to accommodate the human interaction. An automated system is being developed to replace the operator at the glove box and thus remove the human from these risks, and minimize waste. Although most of the processing can be automated with very little human operator interaction, there are some tasks where intelligent intervention is necessary to adapt to unexpected circumstances and events. These activities will require that the operator be able to interact with the process using a remote manipulator in a manner as natural as if the operator were actually in the work cell. This robot-based remote manipulation system, or telerobot, must provide the operator with an effective means of controlling the robot arm, gripper and tools. This paper describes the effort in progress in Lawrence Livermore National Laboratory to achieve this capability. 8 refs

    The threat of acts of nuclear terrorism in all its forms and manifestations create the urgent need to enhance international cooperation between countries in designing and following practical and effective measures for the prevention of acts of terrorism and to counter and punish its offenders. Several United Nations Security Council Resolutions, such as UNSCR Number 1373 (2001), and UNSCR Number 1540 (2005), and the result of Nuclear Security Summit in 2010 that encourage the member countries of IAEA to ratify nuclear conventions as soon as possible, are the reasons that the Indonesian Government planning on ratifying The International Convention for The Suppression of Acts of Nuclear Terrorism (Nuclear Terrorism Convention). Nuclear Terrorism Convention is one of the 16 (sixteen) international instruments that must be ratified by the member countries of IAEA. Of the 16 (sixteen) international instruments, 3 (three) conventions are related to nuclear; Convention on the Physical Protection of Nuclear Material, Amendment to the Convention on the Physical Protection of Nuclear Material, dan Nuclear Terrorism Convention. This paper presents the preliminary assessment on the differences of Nuclear Terrorism Convention to The Convention on The Physical Protection of Nuclear Material and Amendment to The Convention on The Physical Protection of Nuclear Material. This assessment is important due to the plan of the Indonesian Government to ratify the Nuclear Terrorism Convention. The result of this assessment could be used by BAPETEN in the ratification process of the Nuclear Terrorism Convention. The method used in this assessment is references assessment. (author)

    Full text: The widening of export streams satisfies the interest of any state, but at the same time the interests of individual countries and the whole international community requires the limitation of export of goods and technologies which are potentially dangerous. The decision of this problem, finding of the optimal balance between the devotion of the principles of free trade and the necessity of limiting the danger export is one of the main tasks of the national system of security of the Republic of Kazakhstan. Kazakhstan is a country with a policy of nonproliferation. This important element of the policy of the country, directed to maintenance and strengthening of the international security, becomes the priority trend in the foreign policy of Kazakhstan. The international community decides this problem under the Comprehensive Nuclear Test Ban Treaty (CTBT), Treaty on the Non-Proliferation of Nuclear Weapons (NPT), and the Convention on the Prohibition of the Development Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on the Destruction, Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and Their Destruction. At present there are four international regimes in control with the aim of nonproliferation of the weapons of mass destruction (WMD): The group of the nuclear supplies which deals with the questions of delivery of special nuclear materials and technologies, and also nuclear materials and double function technologies; Australian group works in the sphere of control for materials and technologies of chemical and biological weapons; The regime of the control of rocket technologies functioning with the aim to prevent the proliferation of rockets as means of delivery of weapon of mass destruction; Wassenaar agreement, regime of export control for usual armament, goods and double function technologies.

    2015-01-01

    The State System of Accounting and Control of Nuclear Material (SSAC) in South Africa comprises a State Inspectorate, Technical Support and Safeguards Information Systems (SIS). SIS is responsible for the quality control and assurance of the Nuclear Material Reports, Additional Protocol declarations and submission to the IAEA. Monthly reports are received from the facilities where inventory changes took place. Reports are prepared according to a Quality Management Document: Instruction for the Completion of Nuclear Material Accounting Reports. The inventory changes are reported on spreadsheets developed for our system. The Inventory Change Reports (ICR) and General Ledgers (GL) are compared line by line to check for discrepancies, which will be noted on a Control Sheet. The form will be sent to the relevant facility to notify them of corrections needed. The corrected reports will be re-submitted to SIS. A spreadsheet is used in the verification process with columns for all material categories and inventory change codes. The ICR totals of all inventory changes can be reconciled with the GL values. If all the entries are correct the nuclear material totals should be the same as on the GL. The facility file is checked by the State Inspector responsible for the specific facility as a second round of quality control. The inspector is required to sign the Control Sheet to confirm the completeness and correctness of the reports. The Excel data is then converted into a text (.txt) file, encrypted and then submitted electronically to the Agency. This paper will present all the steps involved in ensuring the correctness of the reports and the quality control measures in detail used by the South Africa SSAC. (author)

    Nuclear forensic science seeks to identify the origin of nuclear materials found outside regulatory control. It is increasingly recognized as an integral part of a robust nuclear security program. This review highlights areas of active, evolving research in nuclear forensics, with a focus on analytical techniques commonly employed in Earth and planetary sciences. Applications of nuclear forensics to uranium ore concentrates (UOCs) are discussed first. UOCs have become an attractive target for nuclear forensic researchers because of the richness in impurities compared to materials produced later in the fuel cycle. The development of chronometric methods for age dating nuclear materials is then discussed, with an emphasis on improvements in accuracy that have been gained from measurements of multiple radioisotopic systems. Finally, papers that report on casework are reviewed, to provide a window into current scientific practice.

    1989-01-01

    The report describes major items planned to be incorporated into the enforcement regulations for laws relating to control of nuclear material, nuclear fuel and nuclear reactor. The modifications have become necessary for the nation to conclude a nuclear material protection treaty with other countries. The modification include the definitions of 'special nuclear fuel substances' and 'special nuclear fuel substances' and 'special nuclear fuel substances subject to protection'. The modifications require that protective measures be taken when handling and transporting special nuclear fuel substances subject to protection. Transport of special nuclear fuel substances requires approval from the Prime Minister or Transport Minister. Transport of special nuclear fuel substances subject to protection should be conducted after notifying the prefectural Public Safety Commission. Transport of special nuclear fuel substances subject to protection requires the conclusion of arrangements among responsible persons and approval of them from the Prime Minister. (N.K.)

    A measurement evaluation program (MEP) is one of a number of valuable tools that analytical chemists can use to ensure that the data produced in the laboratory are fit for their intended purpose and consistent with expected performance values at a given time. As such, participation in a MEP is an important indicator of the quality of analytical data, and is recognized as such by independent regulatory and/or accreditation bodies. With the intent to implement such a program in Brazil, in November 2012 the Nuclear Energy Commission of Brazil (CNEN), with support from the Department of Energy of the United States' (US-DOE International Safeguards and Engagement Program), decided to initiate a technical cooperation project aiming at organizing a Safeguards Measurement Evaluation Program (SMEP) for Brazilian facilities. The project, entitled Action Sheet 23, was formalized under the terms of the Agreement between the US-DOE and the CNEN concerning research and development in nuclear material control, accountancy, verification, physical protection, and advanced containment and surveillance technologies for International Safeguards Applications. The work, jointly performed by the CNEN's Safeguards Laboratory (LASAL) and the New Brunswick Laboratory (NBL), has the objective to strengthen the traceability of accountability measurements and ensure adequate quality of safeguards measurements for facilities within Brazil, utilizing test samples characterized and provided by NBL. Recommendations to participants included measurement frequency, number of results per sample and format for reporting results using ISO methods for calculating and expressing measurement uncertainties. In this paper, we discuss the main steps taken by CNEN and NBL aiming at implementing such a program and the expected results, in particular the impact of uncertainty estimation on the evaluation of performance of each participant laboratory. The program is considered by Brazilian safeguards

    In 1998, Nuclear Regulatory Authority of the Slovak Republic (NRA SR) performed 38 inspections, 25 of them were performed in co-operation with IAEA inspectors. There is no fresh nuclear fuel at Bohunice A-1 NPP at present. Fresh fuel of Bohunice V-1 and V-2 NPPs is inspected in the fresh fuel storage.There are 327 fresh fuel assemblies in Mochovce NPP fresh fuel storage. In addition to that, are also 71 small users of nuclear materials in Slovakia. In most cases they use: covers made of depleted uranium for non-destructive works, detection of level in production plants, covers for therapeutical sources at medical facilities. In. 1995, NRA SR issued 4 new licences for nuclear material withdrawal. In the next part manipulation with nuclear materials, spent fuel stores and illegal trafficking in nuclear materials are reported

    1977-10-01

    The feasibility of using modern state estimation techniques (specifically Kalman Filtering and Linear Smoothing) to detect losses of material from material balance areas is evaluated. It is shown that state estimation techniques are not only feasible but in most situations are superior to existing methods of analysis. The various techniques compared include Kalman Filtering, linear smoothing, standard control charts, and average cumulative summation (CUSUM) charts. Analysis results indicated that the standard control chart is the least effective method for detecting regularly occurring losses. An improvement in the detection capability over the standard control chart can be realized by use of the CUSUM chart. Even more sensitivity in the ability to detect losses can be realized by use of the Kalman Filter and the linear smoother. It was found that the error-covariance matrix can be used to establish limits of error for state estimates. It is shown that state estimation techniques represent a feasible and desirable method of theft detection. The technique is usually more sensitive than the CUSUM chart in detecting losses. One kind of loss which is difficult to detect using state estimation techniques is a single isolated loss. State estimation procedures are predicated on dynamic models and are well-suited for detecting losses which occur regularly over several accounting periods. A single isolated loss does not conform to this basic assumption and is more difficult to detect.

  12. Novel Problems Associated with Accounting and Control of Nuclear Material from Decontamination and Decommissioning and in Waste

    Schlegel, Steven C.

    2007-01-01

    The reduction in nuclear arms and the production facilities that supported the weapons programs have produced some unique problems for nuclear material control and accountability (MC and A). Many of these problems are not limited to the weapons complex, but have the potential to appear in many legacy facilities as they undergo dismantlement and disposal. Closing facilities find that what was previously defined as product has become a waste stream bringing regulatory, human, and technological conflict. The sometimes unique compositions of these materials produce both storage and measurement problems. The nuclear material accounting and control programs have had to become very adaptive and preemptive to ensure control and protection is maintained. This paper examines some of the challenges to Safeguards generated by deinventory, decontamination decommissioning, dismantlement, demolition, and waste site remediation from predictable sources and some from unpredictable sources. 1.0 Introduction The United States is eliminating many facilities that support the nuclear weapons program. With the changing political conditions around the world and changes in military capabilities, the decreased emphasis on nuclear weapons has eliminated the need for many of the aging facilities. Additionally, the recovery of plutonium from dismantled weapons and reuse of components has eliminated the need to produce more plutonium for the near future. Because the nuclear weapons program and commercial applications generally do not mix in the United States, the facilities in the DOE complex that no longer have a weapon mission are being deinventoried, decontaminated, decommissioned, and dismantled/demolished. The materials from these activities are then disposed of in various ways but usually in select waste burial sites. Additionally, the waste in many historical burial sites associated with the weapons complex are being recovered, repackaged if necessary, and disposed of in either

    Current DOE regulations for Controlled Nuclear Materials (CNM) management have particular accounting problems that have become more evident as computer systems have been designed and programmed to automate the materials accounting functions. Some valuable detailed accounting information is lost with current accounting procedures and some aspects of the procedures are more complicated than need be. In February, 1988, the authors first recommended that the basic concepts of CNM accountability be reviewed, with particular emphasis on developing an Isotopic accountability system as opposed to the present Material-type accountability system. A parallel effort to review the materials measurement program would also be desirable

    Networking and distributed processing hardware and software have the potential of greatly enhancing nuclear materials control and account-ability (MCandA) systems, both from safeguards and process operations perspectives while allowing timely integrated safeguards activities and enhanced computer security at reasonable cost. A hierarchical distributed system is proposed consisting of groups of terminals and instruments in plant production and support areas connected to microprocessors that are connected to either larger microprocessors or minicomputers. The structuring and development of a limited distributed MCandA prototype system, including human engineering concepts, are described. Implications of integrated safeguards and computer security concepts to the distributed system design are discussed

    Under a contract with the International Atomic Energy Agency, the V.I. Lenin Atomic Reactor Research Institute is currently carrying out a study of ways of organizing a nuclear materials accounting and control system for the BOR-60 fast reactor. Some results of this study are presented in the paper. The special physical and technological features of fast reactors create additional difficulties in safeguards systems and give rise to a number of new possibilities for the illicit removal of nuclear materials. These questions are discussed with reference to the BOR-60 reactor but the conclusions are probably applicable to all fast reactors. The proposed accounting and control system is based on non-destructive measurements of the amount of fissile materials in the operating fuel assemblies and screened bundles of the reactor, on the independent control of the principal facility parameters (a list of which is given) and on an automated information collection and evaluation system. Visual means of inspection can be very effective in fast reactor safeguards systems, especially for controlling storage, but they are not used with the BOR-60 reactor. (author)

    In comparison with other facilities handling nuclear material, a nuclear research centre is characterized by a wider spectrum of operations. This requires a number of installations within the centre such as research reactors, critical assemblies, research institutes and central departments, operating, in general, independently of each other. Nuclear material is stored and processed in small quantities and in different chemical and physical configurations within prescribed license areas. The conceptual design of a new system for nuclear material control in a research centre has to consider the operator's and IAEA's safeguards requirements. Using the example of the Juelich Nuclear Research Centre in the Federal Republic of Germany, these requirements are being examined in conjunction with the specified peculiarities of a nuclear research centre. Following this, a division of the research centre into material balance areas and key measurement points is being proposed, based on the existing facilities and licence areas. The essential characteristic of the concept is a far-reaching displayability of the inventory and flow of nuclear material. The availability of information is based on differentiated material accountancy in conjunction with adequate measurement of nuclear material data. For data processing and generation of data, a computerized record and report system is to be provided as well as a central measurement system. The design of an integrated accountancy system with a central computer and remote terminals is described; various measuring appliances, now being developed or tested, for the non-destructive assay of nuclear material are specified. The functions of a central department for nuclear material management for operating these systems are discussed and the planned verification of nuclear material in the different material balance areas illustrated. On applying the measures described in this paper, the conceptual design of a system for nuclear material

    Nuclear Safety and Security Commission(NSSC) has amended two public notices about the regulation of nuclear material accounting and control(NMAC). Those notices were declared in November 2014 and entry into force since 2015. According to this legislation, a new type of NMAC inspection system was introduced and facility rules for NMAC approved by the government should be revised subsequently. These changes were one of the preemptive actions to cope with the emergence of new international safeguards policy and increasing demand on advanced nuclear technology. Generally, the regulation policy affects the nuclear business including research and development. Therefore, understanding of the new policy and its making process may help stakeholders to minimize unnecessary financial and operational burden. This study describes background, features, and institutionalization of the new regulation policy for NMAC. The new regulation policy for NMAC was established and institutionalized to preemptively cope with the internal and external demand on 'better' national system of accounting and control of nuclear material. This new policy and regulation system may call not only the regulator but also nuclear business operators for new works to make their system more effective and efficient.

    Physical protection against the theft or unauthorized diversion of nuclear materials and against the sabotage of nuclear facilities by individuals or groups has long been a matter of national and international concern. Although responsibility for establishing and operating a comprehensive physical protection system for nuclear materials and facilities within a State rests entirely with the Government of that State, it is not a matter of indifference to other States whether and to what extent that responsibility is fulfilled. Physical protection has therefore become a matter of international concern and co-operation. The need for international co-operation becomes evident in situations where the effectiveness of physical protection in one State depends on the taking by other States also of adequate measures to deter or defeat hostile actions against nuclear facilities and nuclear materials, particularly when such materials are transported across national frontiers [Spanish] La proteccion fisica contra el robo o la desviacion no autorizada de materiales nucleares y contra el sabotaje de las instalaciones nucleares por parte de individuos o grupos es motivo de preocupacion nacional e internacional desde hace mucho tiempo. Aunque la obligacion de crear y hacer funcionar un sistema completo de proteccion fisica de las instalaciones y materiales nucleares en el territorio de un Estado determinado incumbe exclusivamente al Gobierno de dicho Estado, el que esa obligacion se cumpla o no, y si se cumple, en que medida o hasta que punto, son cosas que no dejan indiferentes a los demas Estados. Por ello, la proteccion fisica se ha convertido en motivo de interes y cooperacion internacional. La necesidad de la cooperacion internacional se hace evidente en los casos en que la eficacia de la proteccion fisica en el territorio de un Estado depende de que otros Estados tomen tambien medidas apropiadas para evitar o hacer fracasar los actos hostiles dirigidos contra instalaciones y

    The nuclear regulatory activities in Argentina are carried out by the 'Nuclear Regulatory Authority' (ARN). To fulfil its responsibilities, the ARN has established and enforced a regulatory framework for all nuclear activities concerning nuclear safety and radiological protection, physical protection and the guarantees of non-proliferation. Concerning the guarantees of non-proliferation, the SSAC includes an independent verification system based on national safeguards inspections, evaluations and a centralised accounting database of all nuclear materials in all nuclear activities performed in Argentina. The ARN has implemented two computerised databases to improve its SSAC. One is the 'Safeguards Inspections System' (SIS) developed to optimise the programming of the national inspections and their evaluation. The other is the 'Nuclear Material Control System' (SCMN) designed to improve the issuing and submission of accounting and operating reports. To improve further the SSAC, the ARN has requested software that should be in use at each nuclear installation in the near future. This computerised accounting database (SOP) would increase the quality of the operator's accounting and control system. About the change of the millennium, it is important to bear in mind that it may have an impact not only in the dates of the safeguards reports, but also in some data generated by software or equipment at nuclear installations used as the basis for safeguards records. For example, computerised programs for fuel element management at the Nuclear Power Stations or certain software and hardware in use at bulk installations would require a comprehensive review to assure that the change of the year 2000 will not cause any problem. Besides, some of the data generated by computerised systems at the level of installations are inputs for the three integrated databases SCMN, SIS and SOP. This paper describes the objectives and functions of these integrated systems and some main aspects

  12. Nuclear material control and accounting system evaluation in uranium conversion operations

    Moreira, Jose Pontes

    1994-01-01

    The Nuclear Material Control and Accounting Systems in uranium conversion operations are described. The conversion plant, uses ammonium diuranate (ADU), as starting material for the production of uranium hexafluoride. A combination of accountability and verification measurement is used to verify physical inventory quantities. Two types of inspection are used to minimize the measurements uncertainty of the Material Unaccounted For (MUF) : Attribute inspection and Variation inspection. The mass balance equation is the base of an evaluation of a Material Balance Area (MBA). Statistical inference is employed to facilitate rapid inventory taking and enhance material control of Safeguards. The calculation of one sampling plan for a MBA and the methodology of inspection evaluation are also described. We have two kinds of errors : no detection and false delation. (author)

    The Argonne National Laboratory and Sandia National Laboratory have recently installed an activated barrier, the Access Denial System (ADS) for the upgrade of safeguards of special nuclear materials. The technology of this system was developed in the late 70's by Sandia National Laboratory-Albuquerque. The installation was the first for the Department of Energy. Subsequently, two additional installations have been completed. The Access Denial System, combined with physical restraints, provide the system delay. The principal advantages of the activated barrier are: (1) it provides an order of magnitude improvement in delay over that of a fixed barrier, (2) it can be added to existing vital areas with a minimum of renovations, (3) existing operations are minimally impacted, and (4) health and safety risks are virtually nonexistent. Hardening of the vital areas using the ADS was accomplished in a costeffective manner

    Most enterprises in the Russian Federation are not prepared to report to the Russian Federal Nuclear Material Control and Accounting Information System (FIS) by the full function reporting method. The full function reporting method requires reporting inventory listings on a schedule based on nuclear material category, submission of individual inventory change reports, and reconciliation and closeout at the end of each reporting period. Most Russian enterprises do not have automated systems and do not have the resources to develop and implement such systems. Over the last two years, MinAtom put the regulations and national level nuclear material control and accounting (MC and A) software in place to require all enterprises in the Russian Federation to report summarized inventory listings to the FIS in January 2002. Enterprises do not need automated systems to comply with summarized reporting requirements. Along with the approximately 25% of the total Category 1 Material Balance Areas (MBAs) using full function reporting, the addition of this complete summarized inventory makes the FIS a more valuable tool for MinAtom management. The FIS is now poised to complete the work by improving the integrity and reliability of the data through increasing the number of enterprises and MBAs using full function reporting. There are obstacles and issues that must be dealt with along the way to achieving the final goal of every MBA sending inventory and inventory change reports using the full function reporting method. Summarized reporting is a major step toward this final goal. Currently all MBAs using full function reporting are doing so under a U.S. contract. FIS management recognized full function reporting could not be implemented in the near-term and prepared a plan with immediate, intermediate, and long-term FIS tasks. To address the major obstacles and optimize implementation, two paths need to be followed in parallel: developing the regulatory basis and overcoming

    Full text: The nuclear materials should be controlled under the regulation of National Safeguard System. The non-destructive analysis method, which is simple and quick, provide a effective process in determining the nuclear materials, nuclear scraps and wastes. The method play a very important role in the fields of nuclear material control and physical protection against the illegal removal and smuggling of nuclear material. The application of non-destructive analysis in attributes identification of nuclear material is briefly described in this paper. The attributes determined by radioactive detection technique are useful tolls to identify the characterization of special nuclear material (isotopic composition, enrichment etc.). (author)

    2015-01-01

    The Brazilian Nuclear Energy Commission (CNEN) is the government organization responsible for regulating all nuclear activities in Brazil and for ensuring that international safeguards are implemented according to the international agreements. In 2006 CNEN initiated a project aiming at the development and implementation of a web based system (e-Gamma) for on line nuclear material accountancy and control. In January-2014, after three years of beta testing, e-Gamma finally became the official nuclear material accountancy system in Brazil. e-Gamma is a web system hosted in a dedicated server under a secure environment maintained at CNEN headquarters. Secure access is provided by the use of Digital Client Certificate and internal user pre-authorization for login as well as multiple access profiles each one with specific function menus. The System operation is based on source documents for each inventory change prepared and updated by the MBA operators with the help of specific forms with strong validations. After the document conclusion the System records the inventory change in a general ledger. Monthly the officers of CNEN analyzes the general ledgers of each MBA and generates the applicable reports through the System [Inventory Change Reports (ICR), Physical Inventory List (PIL), and Material Balance Report (MBR)]. The System allows the running of managerial queries and has brought to CNEN much more control and traceability of the inventory changes and significant reduction in typing errors, costs and inspection efforts. Therefore, more efficient accountancy verification procedures at national and international levels are expected, as well as remote accountancy verification previous to an inspection. The proposed paper will describe the e-Gamma System, its main features and the oral presentation will contain a brief demonstration of some functionalities through the use of a local version installed on a notebook.

    2001-01-01

    With increased requirements for process control and accountability of nuclear materials in plutonium reprocessing plants, the PC based controlled potential coulometric titrator was developed which has the capability of automatic quantitative analysis of the samples. The instruments based on electromechanical methods, incorporates an electronic potentiostat, a digital coulometer with wide dynamic range and a PC with a control interface card. The potentiostat is required to control the potential at the working electrode surface as per predetermined controlled voltage with respect to a reference electrode under wide variations in the conductivity and double layer capacitance of the electrochemical cell. The digital coulometer precisely measures the amount of electronic charge taking part in the electrochemical reactions of interest. The software has the facility to carry out three different types of analysis, i.e., primary coulometry, secondary coulometry and coulogram curve tracing. Due to complete analysis of the samples under program control, the human related errors are minimized and a better precision in the results are obtained. It has been possible to obtain an overall precession of better than +/- 0.3% in the determination of plutonium using the instrument. (author)

  5. Auditing nuclear materials statements

    1973-01-01

    A standard that may be used as a guide for persons making independent examinations of nuclear materials statements or reports regarding inventory quantities on hand, receipts, production, shipment, losses, etc. is presented. The objective of the examination of nuclear materials statements by the independent auditor is the expression of an opinion on the fairness with which the statements present the nuclear materials position of a nuclear materials facility and the movement of such inventory materials for the period under review. The opinion is based upon an examination made in accordance with auditing criteria, including an evaluation of internal control, a test of recorded transactions, and a review of measured discards and materials unaccounted for (MUF). The standard draws heavily upon financial auditing standards and procedures published by the American Institute of Certified Public Accountants

  6. Proposals for the Future Development of the Russian Automated Federal Information System for Nuclear Material Control and Accounting: The Universal Reporting Concept

    Martyanov, Alexander; Pitel, Victor; Kasumova, Leila; Babcock, Rose A.; Heinberg, Cynthia L.

    2004-01-01

    Development of the automated Russian Federation Federal Information System for Nuclear Material Control and Accounting (FIS) started in 1996. From the beginning, the creation of the FIS was based on the concept of obtaining data from the material balance areas of the organizations, which would enable the system to collect detailed information on nuclear material. In December 2000, the organization-level summarized reporting method was mandated by the Russian Federation and subsequently implemented for all organizations. Analysis of long-term FIS objectives, reporting by all the MBAs in Russia, showed that the present summarized reporting approach decreed by regulations posed a fair number of problems. We need alternative methods that allow the FIS to obtain more detailed information on nuclear material but which accurately reflect the technical and economic resources available to Russian organizations. One possible solution is the universal reporting method. In August 2003, the proposals of the FIS working group to transition to the universal reporting method were approved at the fourth meeting of the Joint Coordinating Committee for Implementation of the Russian Federation and U.S. Government-to-Government Agreement on Cooperation in the Area of Nuclear Material Physical Protection, Control and Accounting (JCC). One of the important elements of universal reporting is that organizations handling nuclear material will establish 'reporting areas' in cooperation with MinAtom of Russia. A reporting area may consist of one MBA, several MBAs, or even an entire organization. This paper will discuss the universal reporting concept and its major objectives and methods for the FIS.

    International Nuclear Information System (INIS)

    Ross, A.M.

    1983-01-01

    This paper describes the operating experience of INMACS, the Integrated Nuclear Material Accounting and Control System used in the Recycle Fuel Fabrication Laboratories at Chalk River. Since commissioning was completed in 1977, INMACS has checked and recorded approximately 3000 inventory-related transactions involved in fabricating thermal-recycle fuels of (U,Pu)0 2 and (Th,Pu)0 2 . No changes have been necessary to INMACS programs that are used by laboratory staff when moving or processing nuclear material. The various utility programs have allowed efficient management and surveillance of the INMACS data base. Hardware failures and the nuisance of system unavailability at the laboratory terminals have been minimized by regular preventative maintenance. The original efforts in the design and rigorous testing of programs have helped INMACS to be accepted enthusiastically by old and new staff of the laboratories. The work required for nuclear material inventory control is done efficiently and in an atmosphere of safety

    1989-01-01

    The legislative basis, structure, functions, records and experience of the State System of Accounting for and Control of Nuclear Materials (SSAC) in the German Democratic Republic (GDR) are reviewed. The GDR's nuclear activities are characterized by research establishments and power reactors and by the absence of industrial bulk handling facilities such as fuel fabrication, reprocessing and enrichment plants. As a consequence both the national and the international safeguards approach can be based on the principles of item accountability which does not require the establishment of an elaborate measurement system. Right from the beginning the safeguards implemented were of the NPT type as the GDR was among the early parties to the Non-Proliferation Treaty. The national rules and procedures of safeguards were thus established in harmony with the international requirements and have closely followed their development. The SSAC in the GDR is part of the comprehensive set-up of protective measures against the potential hazards in the use of nuclear energy under the National Board for Atomic Safety and Radiation Protection which has established a number of inspectorates, among them the inspection group for nuclear material control -the Nuclear Material Inspectorate. 5 figs., 2 tabs

    Rometsch, R.; Hough, G.

    1977-01-01

    IAEA Safeguards, which are always implemented on the basis of agreements which are concluded between one or more Governments and the IAEA, lay down the rights and obligations of the parties; and the more modern types of agreement, in particular those in connection with the Treaty on the Non-Proliferation of Nuclear Weapons, do this in quite some detail. Several articles, for instance, regulate the working relations between the States and the IAEA inspectorate. These are based on two basic obligations - that of the State to establish and maintain a ''System of Accountancy for and Control of Nuclear Material'' and that of the IAEA to ascertain the absence of diversion of nuclear material by verifying the findings of the States' systems, inter alia through independent measurements and observations. Other articles dealing also with the working relations between States and the IAEA rule that the IAEA should take due account of the technical effectiveness of the States' systems and mention among the criteria for determining the inspection effort, the extent of functional dependence of the State's accountancy on that of the facility operator. However, quantitative relationships in this respect are left to be worked out in practice. With the help of consultants and expert advisory groups a rationale has been developed and possible practical arrangements discussed with several States concerned. The rationale for co-ordinating the work of the States' inspectorate with that of the IAEA was to use a factor by which the significant quantity used for calculating verification sampling plans would be adjusted so as to reduce to a certain extent the IAEA's independent verification work in case the States would themselves do extensive verifications in a manner transparent to the IAEA. However, in practice it proved that there are a number of points in the fuel cycle where such adaptations would have little or no effect on the inspection effort necessary to achieve the safeguards

    Barham, M.A.; Abbott, R.R.

    1991-01-01

    The increase in emphasis on the adequacy of the NMC and A internal control systems requires that management define what type of training and experience is needed by NMC and A Internal Audit Program. At Martin Marietta Energy Systems, inc. (the prime contractor for the Department of Energy at Oak Ridge, Tenn.), the Central NMC and A Manager has developed a comprehensive set of NMC and A Internal Audit policies that defines performance standards, methods of conducting audits, mechanisms for ensuring appropriate independence for NMC and A auditors, structure for standardized audit reports and working papers, and a section that addresses the development of training plans for individual NMC and A auditors. The training requirements reflect the unique combination of skills necessary to be an effective NMC and A Internal Auditor- a combination of the operational auditing skills of a Certified Internal Auditor, the accounting auditing capabilities of a Certified Public Accountant, and the specific technical knowledge base associated with nuclear materials. This paper presents a mechanism for identifying an individual training program for NMC and A auditors that considers the above requirements and the individual's long-range career goals

    The objective of physical protection, its statutory and other bases as well as the parties involved in the licensing process are described. The facilities are grouped in categories reflecting their hazard potentials: the possibility of a theft of nuclear fuels in an approach similar to INFCIRC 225 and, in addition, the possibility of a release of radioactive materials. Physical protection follows the concept of detection, alert of police force, delay, prevention of the act by police force. The schematic layout of a Category I facility is presented

    2002-01-01

    In July 2001 an incident was recognized where a worker occupied with decontamination of structures in a shut down reprocessing plant for spent fuel illegally removed a small amount of radioactive material from the facility site. The investigations exhibited that he brought this material to the apartment of his partner in life and she incorporated significantly α-activity in the form of plutonium. Immediately after the incident was discovered the supervisory authorities and the operating company of the facility took action to minimize the harms to third parties arising from the radioactive material released and to prevent a similar event to occur. As the overall inventory of radioactive material in the shut down facility at the time the theft occurred was below the limit where measures of physical protection are required by the German regulatory work discussions were raised on consequences to be drawn from this incident to close this obvious gap. The German Federal Ministry for Environment, Nature Protection and Reactor Safety (BMU) as the superior competent authority therefore ordered GRS to draft a set of fundamental requirements for future rules to make a repetition of the initiating incident unlikely. Further discussions of the authorities involved on supplementary rules and guidelines aiming to better protect small amounts of radioactive material from being illegally removed out of nuclear facilities and laboratories are based on these fundamentals defined by GRS but not yet finished.

  17. The nuclear materials contraband

    International Nuclear Information System (INIS)

    Williams, P.; Woessner, P.

    1996-01-01

    Several seizures of nuclear materials carried by contraband have been achieved. Some countries or criminal organizations could manufacture atomic bombs and use them. This alarming situation is described into details. Only 40% of drugs are seized by the American police and probably less in western Europe. The nuclear materials market is smaller than the drugs'one but the customs has also less experience to intercept the uranium dispatch for instance more especially as the peddlers are well organized. A severe control of the international transports would certainly allow to seize a large part of nuclear contraband materials but some dangerous isotopes as uranium 235 or plutonium 239 are little radioactive and which prevents their detection by the Geiger-Mueller counters. In France, some regulations allow to control the materials used to manufacture the nuclear weapons, and diminish thus the risk of a nuclear materials contraband. (O.L.). 4 refs., 2 figs

    2017-01-01

    With entry into force of the 2005 Amendment to the Convention on the Physical Protection of Nuclear Material (CPPNM) on May 8, 2016, and the culmination of the Nuclear Security Summits (NSS), the Convention on the Physical Protection of Nuclear Materials and Nuclear Facilities (CPP), as the amended convention is now known, can play an increasingly important role in efforts to strengthen the international nuclear security architecture. The CPP significantly enhances the international legal framework for nuclear security by expanding the scope of physical protection requirements and providing a direct linkage to International Atomic Energy Agency (IAEA) nuclear security guidance through incorporation of the Fundamental Principles.The CPP’s entry into force requires states parties to submit reports to the IAEA under Article 14 informing the IAEA of its laws and regulations giving effect to the convention—states parties were required to do so under the original CPPNM, but the scope of the reports will need to expand to reflect the expanded scope of the convention. Reporting builds confidence in the effectiveness of states’ security. In addition, entry into force of the CPP requires the IAEA, under Article 16, to convene a review conference in five years to assess the implementation and adequacy of the convention “in light of the then prevailing situation.” The review conference will provide an opportunity for states parties to assess the status of nuclear security progress and will provide a forum for dialogue on how to strengthen the global architecture and address remaining gaps in the system. Article 16 also provides for additional review conferences at periods of at least five years if requested by a majority of states parties. Regular review conferences would be an important mechanism for sustaining attention on nuclear security and ensuring continued nuclear security progress. For the CPP to fulfill its potential to play an important role in

    1994-01-01

    The 1993 annual report of the Brazilian Argentine Agency for Accounting and Control of Nuclear Materials, (ABACC), describes the activities regarding the administration and application of the Control and Accounting Common System (SCCC) established by the bilateral agreement between the Republic of Argentine and Federative Republic of Brazil for exclusive peaceful use of the nuclear energy. The main goal to verify practically all the installations which were not subjected to the international safeguards, before the agreement, was reached. Considering the safeguards application under implementation in both countries, the ABACC is preparing itself technically for the quadripartite agreement to be into force and signed among Argentine, Brazil, IAEA and ABACC. On checking the procedures established by the SCCC and controlled material, nothing was detected that could indicate nuclear material diversion either for nuclear weapon or for other explosive nuclear device.

    Argentina and Brazil began its activities in the nuclear area about the same time, in the 50 century past. The existence of an international nuclear nonproliferation treaty-TNP-seen by Brazil and Argentina as discriminatory and prejudicial to the interests of the countries without nuclear weapons, led to the need for a common system of control of nuclear material between the two countries to somehow provide assurances to the international community of the exclusively peaceful purpose of its nuclear programs. The creation of a common system, assured the establishment of uniform procedures to implement safeguards in Argentina and Brazil, so the same requirements and safeguards procedures took effect in both countries, and the operators of nuclear facilities began to follow the same rules of control of nuclear materials and subjected to the same type of verification and control. On July 18, 1991, the Bilateral Agreement for the Exclusively Peaceful Use of Nuclear Energy created a binational body, the Argentina-Brazil Agency for Accounting and Control of Nuclear Materials-ABACC-to implement the so-called Common System of Accounting and Control of Nuclear materials - SCCC. The deal provided, permanently, a clear commitment to use exclusively for peaceful purposes all material and nuclear facilities under the jurisdiction or control of the two countries. The Quadripartite Agreement, signed in December of that year, between the two countries, ABACC and IAEA completed the legal framework for the implementation of comprehensive safeguards system. The 'model ABACC' now represents a paradigmatic framework in the long process of economic, political, technological and cultural integration of the two countries. Argentina and Brazil were able to establish a guarantee system that is unique in the world today and that consolidated and matured over more than twenty years, has earned the respect of the international community

    The Department of Energy (Department) is responsible for safeguarding a significant amount of plutonium, uranium-233 and enriched uranium - collectively referred to as special nuclear materials - stored in the United States. The Department`s office of Nonproliferation and National Security has overall management cognizance for developing policies for safeguarding these materials, while other Headquarters program offices have {open_quotes}landlord{close_quotes} responsibilities for the sites where the materials are stored, and the Department`s operations and field offices provide onsite management of contractor operations. The Department`s management and operating contractors, under the direction of the Department, safeguard and account for the special nuclear material stored at Department sites.

    Safeguards had its beginning in the early 1940s and has continued to grow through the stormy years in dealing with nuclear materials. MC and A Plans have been developed for each facility which includes requirements for containment, surveillance, internal controls, measurements, statistics, records and report systems, and inventory certification of its nuclear materials, in the context of how precisely the inventory is known at stated risk or confidence levels. The I and E Regulations, the newest document affecting the control system, are used for testing the current MC and A plan in place at each facility. Nuclear Materials Management activities also have reporting requirements that include: (1) Annual Forecast, (2) Materials Management Plan, (3) Quarterly Status Report, (4) Assessment Report, and (5) Scrap and Excess Material Management. Data used to generate reports for both functions come from the same data base and source documents at most facilities. The separation of sponsoring groups at the DOE for NM Accountability and NM Management can and does pose problems for contractors. In this paper, we will try to separate and identify these overlaps at the Facility and DOE level

    A Nuclear Material Control and Accountability (MC and A) Functional Model has been developed to describe MC and A systems at facilities possessing Category I or II Special Nuclear Material (SNM). Emphasis is on achieving the objectives of 144 'Fundamental Elements' in key areas ranging from categorization of nuclear material to establishment of Material Balance Areas (MBAs), controlling access, performing quality measurements of inventories and transfers, timely reporting all activities, and detecting and investigating anomalies. An MC and A System Effectiveness Tool (MSET), including probabilistic risk assessment (PRA) technology for evaluating MC and A effectiveness and relative risk, has been developed to accompany the Functional Model. The functional model and MSET were introduced at the 48th annual International Nuclear Material Management (INMM) annual meeting in July, 20071,2. A survey/questionnaire is used to accumulate comprehensive data regarding the MC and A elements at a facility. Data is converted from the questionnaire to numerical values using the DELPHI method and exercises are conducted to evaluate the overall effectiveness of an MC and A system. In 2007 a peer review was conducted and a questionnaire was completed for a hypothetical facility and exercises were conducted. In the first quarter of 2008, a questionnaire was completed at Idaho National Laboratory (INL) and MSET exercises were conducted. The experience gained from conducting the MSET exercises at INL helped evaluate the completeness and consistency of the MC and A Functional Model, descriptions of fundamental elements of the MC and A Functional Model, relationship between the MC and A Functional Model and the MC and A PRA tool and usefulness of the MSET questionnaire data collection process

    The Nuclear Regulatory Commission is considering the use of maximum-loss performance criteria as a means of controlling SNM in nuclear plants. The Controllable Unit Approach to material control and accounting (CUA) was developed by Mound to determine the feasibility of controlling a plant to a performance criterion. The concept was tested with the proposed Anderson, SC, mixed-oxide plant, and it was shown that CUA is indeed a feasible method for controlling a complex process to a performance criterion. The application of CUA to an actual low-enrichment plant to assist the NRC in establishing performance criteria for uranium processes is discussed. 5 refs

    The handbook documents existing best practices and methods used to account for nuclear material and to prepare the required nuclear material accounting reports for submission to the IAEA. It provides a description of the processes and steps necessary for the establishment, implementation and maintenance of nuclear material accounting and control at the material balance area, facility and State levels, and defines the relevant terms. This handbook serves the needs of State personnel at various levels, including State authorities, facility operators and participants in training programmes. It can assist in developing and maintaining accounting systems which will support a State's ability to account for its nuclear material such that the IAEA can verify State declarations, and at the same time support the State's ability to ensure its nuclear security. In addition, the handbook is useful for IAEA staff, who is closely involved with nuclear material accounting. The handbook includes the steps and procedures a State needs to set up and maintain to provide assurance that it can account for its nuclear material and submit the prescribed nuclear material accounting reports defined in Section 1 and described in Sections 3 and 4 in terms of the relevant agreement(s), thereby enabling the IAEA to discharge its verification function as defined in Section 1 and described in Sections 3 and 4. The contents of the handbook are based on the model safeguards agreement and, where applicable, there will also be reference to the model additional protocol. As a State using The handbook consists of five sections. In Section 1, definitions or descriptions of terms used are provided in relation to where the IAEA applies safeguards or, for that matter, accounting for and control of nuclear material in a State. The IAEA's approach in applying safeguards in a State is also defined and briefly described, with special emphasis on verification. In Section 2, the obligations of the State

    Twenty years of almost accident-free transport of nuclear materials is pointed to as evidence of a fundamentally correct approach to the problems involved. The increased volume and new technical problems in the future will require extension of these good practices in both regulations and packaging. The general principles of safety in the transport of radioactive materials are discussed first, followed by the transport of spent fuel and of radioactive waste. The security and physical protection of nuclear shipments is then treated. In discussing future problems, the question of public understanding and acceptance is taken first, thereafter transport safeguards and the technical bases for the safety regulations. There is also said to be a need for a new technology for spent fuel casks, while a re-examination of the IAEA transport standards for radiation doses is recommended. The IAEA regulations regarding quality assurance are said to be incomplete, and more information is required on correlations between engineering analysis, scale model testing and full scale crash testing. Transport stresses on contents need to be considered while administrative controls have been neglected. (JIW)

    Innovative systems with increased sensitivity and resolution are in great demand to detect diversion and to prevent misuse in support of nuclear materials management for the U.S. fuel cycle. Nuclear fission is the most important multiplicative process involved in non-destructive active interrogation. This process produces the most easily recognizable signature for nuclear materials. In addition to thermal or high-energy neutrons, high-energy gamma rays can also excite a nucleus and cause fission through a process known as photofission. Electron linear accelerators (linacs) are widely used as the interrogating photon sources for inspection methods involving photofission technique. After photofission reactions, prompt signals are much stronger than the delayed signals, but it is difficult to quantify them in practical measurements. Delayed signals are easily distinguishable from the interrogating radiation. Linac-based, advanced inspection techniques utilizing the delayed signals after photofission have been extensively studied for homeland security applications. Previous research also showed that a unique delayed gamma ray energy spectrum exists for each fissionable isotope. In this work, high-energy delayed γ-rays were demonstrated to be signatures for detection, identification, and quantification of special nuclear materials. Such γ-rays were measured in between linac pulses using independent data acquisition systems. A list-mode system was developed to measure low-energy delayed γ-rays after irradiation. Photofission product yields of 238U and 239Pu were determined based on the measured delayed γ-ray spectra. The differential yields of delayed γ-rays were also proven to be able to discriminate nuclear from non-nuclear materials. The measurement outcomes were compared with Monte Carlo simulation results. It was demonstrated that the current available codes have capabilities and limitations in the simulation of photofission process. A two

    Full text: In expert training on physical protection of nuclear materials (NMPP) an educational and laboratory base has special importance. In these laboratories the students receive practical skills concerning physical protection systems (PPS). The basic requirements for creating such base are formulated in a certain educational program implemented at an educational institution. Thus it is necessary to take into account the following features of a modern nuclear object PPS: restriction of an object visiting with the purpose of acquaintance with features of a certain object PPS; dynamical change of PPS component nomenclature; increase of use of computer facilities for managing all PPS subsystems; increase of integration degree of separate subsystems in a uniform PPS complex; high cost of PPS components. Taking that into consideration a university, which assumes to begin the expert training on NMPP, is compelled to solve the following tasks: creation of its own laboratory base. The implementation of practical occupations with visiting a nuclear object cannot be executed practically; definition of quantity and structure of educational laboratories. Thus the features of the implemented educational plan should be taken into account in addition; optimization of expenses on laboratory creation. The regular updating of laboratory equipment structure is impossible in a practical manner. Therefore unique correct decision is to supply laboratories with the equipment, which uses the typical technological decisions on performing the basic PPS functions (detection, delay, estimation of a situation, neutralization); development of laboratory work conducting procedures (laboratory practical works); technical support of the created laboratories. The certain experience of solving the listed tasks is accumulated at the Moscow Engineering Physics Institute (State University) (MEPhl) while implementing 'Physical Protection, Control and Accountability of Nuclear Materials' master

    The Brazilian-Argentine Agency (ABACC) and the 'Common System of Accounting and Control of Nuclear Materials' (SCCC) are the result of a process started with nuclear cooperation between Argentina and Brazil. The SCCC reflects a common policy of transparency established by a Bilateral Agreement. Its insertion in the global context was made through a Quadripartite Agreement (Argentina, Brazil, ABBAC, IAEA). This paper describes the role of the State System of Accounting and Control (SSAC) in the framework established in the Bilateral and the Quadripartite Safeguards Agreements and in the context of new trends and perspectives in international safeguards. It could also serve as a example for initiatives in other regions. (author)

  13. A saddle-point for data verification and materials accountancy to control nuclear material

    International Nuclear Information System (INIS)

    Beedgen, R.

    1983-01-01

    Materials accountancy is one of the main elements in international safeguards to determine whether or not nuclear material has been diverted in nuclear plants. The inspector makes independent measurements to verify the plant-operator's data before closing the materials balance with the operator's data. All inspection statements are in principle probability statements because of random errors in measuring the material and verification on a random sampling basis. Statistical test procedures help the inspector to decide under this uncertainty. In this paper a statistical test procedure representing a saddle-point is presented that leads to the highest guaranteed detection probability taking all concealing strategies into account. There are arguments favoring a separate statistical evaluation of data verification and materials accountancy. Following these considerations, a bivariate test procedure is explained that evaluates verification and accountancy separately. (orig.) [de

    The spent fuel storage ponds of a large reprocessing plant La Hague in France are under safeguards by means of a wide range of techniques currently used. These techniques include the nuclear material accountancy an containment/surveillance (C/S). Nondestructive assay, design information verification, and authentication of equipment provided by the operator are also implemented. Specific C/S equipment including video surveillance and unattended radiation monitoring have been developed and implemented in a spent fuel pond of La Hague. These C/S systems named EMOSS and CONSULHA with high degree of reliability and conclusiveness provide the opportunity to improve the efficiency of safeguards, particularly as related to spent fuel storage areas where the accountancy is verified by item counting [ru

    This paper addresses the use of real-time software to assist handlers of fissionable nuclear material. We focus specifically on the issue of workstation mass limits, and the need for handlers to be aware of, and check against, those mass limits during material transfers. Here ''mass limits'' generally refer to criticality safety mass limits; however, in some instances, workstation mass limits for some materials may be governed by considerations other than criticality, e.g., fire or release consequence limitation. As a case study, we provide a simplified reliability comparison of the use of a manual two handler system with a software-assisted two handler system. We identify the interface points between software and handlers that are relevant to criticality safety

Republic of Tajikistan in 1997 signed nuclear weapon non-proliferation treaty. Then in 2004 Safeguards agreement, additional protocol and small quantity protocol were signed. During 5 years Republic of Tajikistan submits information on its nuclear activity as declarations, foreseen in article 2.3 of Additional protocol to Safeguards agreement. Currently 66 declarations are submitted. Information required in accordance with Safeguards agreement and Additional Protocol is figured on that IAEA could compile more detailed and exact conception about nuclear activity in Tajikistan and it has the following purpose: information will lead to more transparency, and make it possible to IAEA to ensure with high extent of confidence that in the framework of declared program, any unstated nuclear activity is concealed; the more exact and comprehensive information, the rare is questions and discrepancies are originating; required information is the basis for effective planning and IAEA activity realization, related not only with safeguards implementation in regard to declared nuclear material but also ensuring of confidence in absence of undeclared nuclear activity in Tajikistan. IAEA inspection mission consisting of Messrs. N.Lazarev and F. Coillou visited Dushanbe in 2008 for verification of republic’s declarations on account for and control of nuclear materials under Additional protocol and Small quantity protocol, as well as consultations were provided on correct declaration completing and providing information on all nuclear materials.

    Jonter, T.

    1999-05-01

    This report deals mainly with the United States nuclear energy policy towards Sweden 1945-1960. Although Sweden contained rich uranium deposits and retained high competence in the natural sciences and technology, the country had to cooperate with other nations in order to develop the nuclear energy. Besides developing the civil use of nuclear power, the Swedish political elite also had plans to start a nuclear weapons programme. From the beginning of the 1950s up to 1968, when the Swedish parliament decided to sign the non-proliferation treaty, the issue was widely debated. In this report, American policy is analyzed in two periods. In the first period, 1945-1953, the most important aim was to prevent Sweden from acquiring nuclear materials, technical know-how, and advanced equipment which could be used in the production of nuclear weapons. The Swedish research projects were designed to contain both a civil and military use of nuclear energy. The first priority of the American administration was to discourage the Swedes from exploiting their uranium deposits, especially for military purposes. In the next period, 1953-1960, the American policy was characterized by extended aid to the development of the Swedish energy programme. Through the 'Atoms for Peace'-programme, the Swedish actors now received previously classified technical information and nuclear materials. Swedish companies and research centers could now buy enriched uranium and advanced equipment from the United States. This nuclear trade was, however, controlled by the American Atomic Energy Commission (AEC). The American help was shaped to prevent the Swedes from developing nuclear weapons capability. From mid-50s Swedish politicians and defence experts realised that a national production of nuclear bombs would cost much more money than was supposed 4-5 years earlier. As a consequence, Swedish officials started to explore the possibilities of acquiring nuclear weapons from United States. The American

    As result of the nuclear integration between Brazil and Argentina, in July 1991 the Agreement for Peaceful Uses of the Nuclear Energy (Bilateral Agreement) was signed and the Brazilian Argentine Agency for Accountancy and Control of Nuclear Material (ABACC) was created [1]. The main role assigned to ABACC was the implementation and administration of the regional control system and the coordination with the International Atomic Energy Agency (IAEA) in order to apply safeguards to all nuclear material in all nuclear activities of Argentina and Brazil. In December 1991 the IAEA, ABACC, Argentina and Brazil signed the Quadripartite Agreement (INFCIRC/435) [2]. The agreement establishes obligations similar to those established by model INFCIRC/153 comprehensive agreements. The Bilateral Agreement establishes that the Parties should make available financial and technical capabilities to support ABACC activities. In order to accomplish this challenge, the National Systems had to improve their structure and capabilities. Through the close interaction with the IAEA and ABACC, the national systems have been enriched by adopting new methodologies, implementing innovative safeguards approaches and providing specialized training to the regional inspectors. All of this also resulted in relevant technical improvements to the regional system as a whole. The approach of both neighborhoods controlling each other increased the confidence between the partners and permitted a better knowledge of their potentialities. The recognized performance of the regional system in the implementation of innovative, efficient and credible safeguards measures increased the confidence of the international community on the implementation of nuclear safeguards in Argentina and Brazil. In this paper, after twenty years of the creation of the ABACC System, the view of the Brazilian and Argentine National Authorities is presented. (authors)

  8. INMACS - An approach to on-line nuclear materials accounting and control in a fuel fabrication environment

    1977-08-01

    Taking advantage of modern system technologies, the concept of an Integrated Nuclear Materials Accounting and Control System (INMACS) was formulated as an alternative solution to manual inventory procedures. The selected approach offers prospects for tackling the more general fissile materials inventory problem while satisfying the immediate requirements of the Fuel Fabrication Pilot Line at CRNL. A PDP-11/40 minicomputer system was purchased, and a Data Base Management System (DBMS) was designed and implemented to provide a uniform file handling capability. The specific requirements of the Pilot Line were met by a package of application programs. About 16 man-years have been spent on the project. INMACS has been installed in the field and its usefulness as an on-line inventory system will be demonstrated in the Pilot Line. (author)

    Only one aspect of nuclear security has been discussed here, a disciplined approach to physical protection systems (PPS) design. The best security against a multitude of threats to the nuclear industry is a dynamic and multifaceted safeguards program. It is one that combines PPS design with employee screening, reliability or behavioral observation programs, procedural control, assessment techniques, response capabilities, and security hardware. To be effective, such a program must be supported by management and applied uniformly to all personnel, including the safeguards and security staff

    Inamura, Tomoaki; Madarame, Haruki

    2009-01-01

    The confidentiality system concerning the physical protection of nuclear materials and nuclear facilities was enacted by revision of the Nuclear Reactor Regulation Law in 2005. We made a comparative analysis with the information security in governmental agencies or financial sectors, in order to consider the way the sensitive information management concerning the physical protection of nuclear materials and nuclear facilities should be. The considerations in this paper are as follows. (1) In order to secure a suitable level of security, close cooperation should be achieved among related governmental agencies. (2) A cycle that continuously evaluates whether suitable management is performed should be established. (3) Excessive secretiveness should be eliminated. (4) An information-sharing system among the related persons beyond the frame of governmental agencies and electricity companies should be established. (5) Improvement in the social acceptability of the sensitive information management is important. (6) Although it is important to perform evaluation by the consideration of suitable balance with information disclosure, it is also important that it is positively shown to society. (author)

  13. Nuclear materials stewardship: Our enduring mission

    Isaacs, T.H.

    1998-01-01

    The US Department of Energy (DOE) and its predecessors have handled a remarkably wide variety of nuclear materials over the past 50 yr. Two fundamental changes have occurred that shape the current landscape regarding nuclear materials. If one recognizes the implications and opportunities, one sees that the stewardship of nuclear materials will be a fundamental and important job of the DOE for the foreseeable future. The first change--the breakup of the Soviet Union and the resulting end to the nuclear arms race--altered US objectives. Previously, the focus was on materials production, weapon design, nuclear testing, and stockpile enhancements. Now the attention is on dismantlement of weapons, excess special nuclear material inventories, accompanying increased concern over the protection afforded to such materials; new arms control measures; and importantly, maintenance of the safety and reliability of the remaining arsenal without testing. The second change was the raised consciousness and sense of responsibility for dealing with the environmental legacies of past nuclear arms programs. Recognition of the need to clean up radioactive contamination, manage the wastes, conduct current operations responsibly, and restore the environment have led to the establishment of what is now the largest program in the DOE. Two additional features add to the challenge and drive the need for recognition of nuclear materials stewardship as a fundamental, enduring, and compelling mission of the DOE. The first is the extraordinary time frames. No matter what the future of nuclear weapons and no matter what the future of nuclear power, the DOE will be responsible for most of the country's nuclear materials and wastes for generations. Even if the Yucca Mountain program is successful and on schedule, it will last more than 100 yr. Second, the use, management, and disposition of nuclear materials and wastes affect a variety of nationally important and diverse objectives, from national

    As one possible means to upgrade licensee safeguards systems, the NRC is exploring a real-time material control concept. The concept incorporates process controls, material containment provisions, and extensive instrumentation. Plants incorporating this concept would be better able to prevent, deter, and detect diversion, and to assure that diversion has not gone undetected. A substantial methods development, evaluation, and preliminary standards development program is under way to develop the basis for future policy decisions

  16. Solution standards for quality control of nuclear-material analytical measurements

    International Nuclear Information System (INIS)

    Clark, J.P.

    1981-01-01

    Analytical chemistry measurement control depends upon reliable solution standards. At the Savannah River Plant Control Laboratory over a thousand analytical measurements are made daily for process control, product specification, accountability, and nuclear safety. Large quantities of solution standards are required for a measurement quality control program covering the many different analytical chemistry methods. Savannah River Plant produced uranium, plutonium, neptunium, and americium metals or oxides are dissolved to prepare stock solutions for working or Quality Control Standards (QCS). Because extensive analytical effort is required to characterize or confirm these solutions, they are prepared in large quantities. These stock solutions are diluted and blended with different chemicals and/or each other to synthesize QCS that match the matrices of different process streams. The target uncertainty of a standard's reference value is 10% of the limit of error of the methods used for routine measurements. Standard Reference Materials from NBS are used according to special procedures to calibrate the methods used in measuring the uranium and plutonium standards so traceability can be established. Special precautions are required to minimize the effects of temperature, radiolysis, and evaporation. Standard reference values are periodically corrected to eliminate systematic errors caused by evaporation or decay products. Measurement control is achieved by requiring analysts to analyze a blind QCS each shift a measurement system is used on plant samples. Computer evaluation determines whether or not a measurement is within the +- 3 sigma control limits. Monthly evaluations of the QCS measurements are made to determine current bias correction factors for accountability measurements and detect significant changes in the bias and precision statistics. The evaluations are also used to plan activities for improving the reliability of the analytical chemistry measurements

    Full text: The State System of Accounting for and Control of Nuclear Materials (SSAC) which is established in the Slovak Republic was developed by the former Czechoslovak Atomic Energy Commission and after splitting of the Czechoslovak Republic in 1993 it has been fully accepted by the regulatory authority of the Slovak Republic. This system is based on requirements of the safeguards agreement between the government of the Czechoslovak Republic and the IAEA (which has been accepted by the government of the Slovak Republic), known as INFCIRC/173. The agreement is conforming to INFCIRC/153 i. e. it is reflecting requirements of the Treaty on the Non - Proliferation of Nuclear Weapons (NPT) which was signed by the government of the Czechoslovak Socialist Republic on 01. 07. 1968 and in March 1993 was accepted by the government of the Slovak Republic. The SSAC in the Slovak Republic has national and international objectives. Organisational and functional elements of the SSAC in the Slovak Republic can be addressed in the following six major areas: a) Authority and Responsibility; b) Laws, Regulations and Other Measures; c) SSAC Information System; d) Establishment of Requirements for Nuclear Materials Accounting and Control; e) Ensuring Compliance; f) Technical Support. Legal Basis for the IAEA inspection activities is an Agreement between the government of the Slovak Republic and the IAEA (INFCIRC/173). The Agreement is supplemented by the Subsidiary Arrangement (SA), which contains in the general part the requirements on accountancy documentation, reports and inspections. The Facility Attachment is a part of SA, which contains information specific for individual MBA, mainly: a brief description of the facility, its purpose, nominal capacity, geographic location, the name and address; location and flow of nuclear materials, a description of features of the facility relating to material accountancy, containment and surveillance; a description of the existing and

    Material control and accountability (MC and A) operations that track and account for critical assets at nuclear facilities provide a key protection approach for defeating insider adversaries. MC and A activities, from monitoring to inventory measurements, provide critical information about target materials and define security elements that are useful against insider threats. However, these activities have been difficult to characterize in ways that are compatible with the path analysis methods that are used to systematically evaluate the effectiveness of a site's protection system. The path analysis methodology focuses on a systematic, quantitative evaluation of the physical protection component of the system for potential external threats, and often calculates the probability that the physical protection system (PPS) is effective (PE) in defeating an adversary who uses that attack pathway. In previous work, Dawson and Hester observed that many MC and A activities can be considered a type of sensor system with alarm and assessment capabilities that provide recurring opportunities for 'detecting' the status of critical items. This work has extended that characterization of MC and A activities as probabilistic sensors that are interwoven within each protection layer of the PPS. In addition, MC and A activities have similar characteristics to operator tasks performed in a nuclear power plant (NPP) in that the reliability of these activities depends significantly on human performance. Many of the procedures involve human performance in checking for anomalous conditions. Further characterization of MC and A activities as operational procedures that check the status of critical assets provides a basis for applying human reliability analysis (HRA) models and methods to determine probabilities of detection for MC and A protection elements. This paper will discuss the application of HRA methods used in nuclear power plant probabilistic risk assessments to define detection

    The multiscale statistical process control (MSSPC) method is applied to clarify the elements of material unaccounted for (MUF) in large scale reprocessing plants using numerical calculations. Continuous wavelet functions are used to decompose the process data, which simulate batch operation superimposed by various types of disturbance, and the disturbance components included in the data are divided into time and frequency spaces. The diagnosis of MSSPC is applied to distinguish abnormal events from the process data and shows how to detect abrupt and protracted diversions using principle component analysis. Quantitative performance of MSSPC for the time series data is shown with average run lengths given by Monte-Carlo simulation to compare to the non-detection probability β. Recent discussion about bias corrections in material balances is introduced and another approach is presented to evaluate MUF without assuming the measurement error model. (author)

    While the responsibility for nuclear security at the national level rests entirely with each state, international co-operation can be crucial in helping states to fulfil their nuclear security responsibilities and obligations. The central role of the International Atomic Energy Agency (IAEA) in strengthening the nuclear security framework and leading the co-ordination of international activities in the field of nuclear security is now widely recognised. Although much has been done to help states in improving nuclear security, by and under the auspices of the IAEA and other intergovernmental organisations, nuclear terrorism has gained a global recognition as one of the most challenging threats to global security in the 21. century Reports by IAEA member states to the IAEA's Incident and Trafficking Database (ITDB) indicate that nuclear material continues to go missing. Also, too many nuclear facilities are still inadequately protected and sabotage thereof is a threat. Border security remains lax in too many places and the possibility for nuclear smuggling may exist. Attempts by individuals and groups of persons are still made to acquire nuclear material for terrorist and other malicious purposes. The threat of nuclear terrorism remains real. Adopted under the auspices of the IAEA on 8 July 2005, the Amendment to the Convention on the Physical Protection of Nuclear Material ('Amendment') and the existing convention, the Convention on the Physical Protection of Nuclear Material (CPPNM or 'Convention') of 1980, are one of a number of treaties comprising the international legal framework on nuclear security. As will be explained later in the article, the Amendment expands and deepens the effect of the CPPNM. However, more than nine years after its adoption and despite the perceived threat and recognised need to strengthen the CPPNM dating back some 15 years ago, the Amendment is still not in force. Although to some CPPNM states parties, the pressing need for the

    1976-07-01

    In signatory states of the Non-Proliferation Treaty nuclear material is subject to the supervision of the International Atomic Energy Agency. The IAEA safeguards concept intended for nuclear material has, so far, been predominantly applied to nuclear facilities of the nuclear fuel cycle. It is the aim of this report to consider the applicability of these control measures to a nuclear research centre. The report refers to the concrete example of the Juelich Nuclear Research Centre (KFA). The particular features of a nuclear research centre and the handling of nuclear material in the KFA are described. A review is given of the various licence areas and permitted handling quantities as well as of the inventories and flow of nuclear material. The concept of a control system for a nuclear research centre satisfying the operator's requirements, national requirement and international obligations at the same time is developed along these lines. The essential characteristic of the concept is a far-reaching clarity of the distribution of nuclear material items within the Nuclear Research Centre. The clarity desired will be achieved by means of an integrated accountancy system processing all necessary data with the aid of a central computer and remote terminals. The availability of information is based on differentiated material acountancy in conjunction with adequate measurement of nuclear material data. In the case of the KFA two groups are formed by research reactors and critical assemblies. Research institutes and central departments the permitted handling quantities of which do not exceed 5 eff.kg constitute a further group. Two further groups are formed for cases where the permitted handling quantities are above or below 1 eff.kg. The report shows the safeguards measures that can be applied in certain circumstances and conditions in a nuclear research centre

    2006-01-01

    The world is at a turning point, moving away from the Cold War nuclear legacy towards a future global nuclear enterprise; and this presents a transformational challenge for nuclear materials management. Achieving safety and security during this transition is complicated by the diversified spectrum of threat 'players' that has greatly impacted nonproliferation, counterterrorism, and homeland security requirements. Rogue states and non-state actors no longer need self-contained national nuclear expertise, materials, and equipment due to availability from various sources in the nuclear market, thereby reducing the time, effort and cost for acquiring a nuclear weapon (i.e., manifestations of latency). The terrorist threat has changed the nature of military and national security requirements to protect these materials. An Integrated Global Nuclear Materials Management (IGNMM) approach would address the existing legacy nuclear materials and the evolution towards a nuclear energy future, while strengthening a regime to prevent nuclear weapon proliferation. In this paper, some preliminary concepts and studies of IGNMM will be presented. A systematic analysis of nuclear materials, activities, and controls can lead to a tractable, integrated global nuclear materials management architecture that can help remediate the past and manage the future. A systems approach is best suited to achieve multi-dimensional and interdependent solutions, including comprehensive, end-to-end capabilities; coordinated diverse elements for enhanced functionality with economy; and translation of goals/objectives or standards into locally optimized solutions. A risk-informed basis is excellent for evaluating system alternatives and performances, and it is especially appropriate for the security arena. Risk management strategies--such as defense-in-depth, diversity, and control quality--help to weave together various technologies and practices into a strong and robust security fabric. Effective

    This guide describes the information required in the physical security plan submitted as part of an application for a license to possess, use, or transport special nuclear material (SNM) of moderate strategic significance or 10 kg or more of SNM of low strategic significance and recommends a standard format for presenting the information in an orderly arrangement. This standards format will thus serve as an aid to uniformity and completeness in the preparation and review of the physical protection plan of the license application. This document can also be used as guidance by licensees possessing or transporting less than 10 kg of SNM of low strategic significance in understanding the intent and implementing the requirements of paragraphs 73.67(a), 73.67(f), and 73.67(g) of 10 CRF Part 73

    The establishment of effective anti-insider measures is a key issue with regard to the physical protection system. The two-man rule, which obligates workers to act always in pairs inside the protected area, is one of the important measures for the anti-insider physical protection system. However, the effectiveness of this method has not been examined in a quantitative manner taking into account the circumstances of Japanese society, which may influence the effectiveness of this method. In this paper, although with several hypotheses, the effectiveness of the two-man rule is confirmed based on the percentage of criminals in the Japanese population. (author)

    1987-01-01

    Residual inventory of nuclear materials remaining in processing facilities (holdup) is recognized as an insidious problem for safety of plant operations and safeguarding of special nuclear materials (SNM). This paper reports on an experimental study where a well-known method of radioanalytical chemistry, namely tracer technique, was successfully used to improve nondestructive measurements of holdup of nuclear materials in a variety of plant equipment. Such controlled measurements can improve the sensitivity of measurements of residual inventories of nuclear materials in process equipment by several orders of magnitude and the good quality data obtained lend themselves to developing mathematical models of holdup of SNM during stable plant operations

    Legislative and regulatory documentation define responsibilities in the field of security and physical protection for transportation of nuclear material. Any transportation activity has to conform to an advance authorization regime delivered by the Ministry of Industry. Responsibility for physical protection of nuclear material rests with the carrier under control of the public authority. Penalties reinforce this administrative regime. Operational responsibility for management and control of transport operations has been entrusted by the ministry to the operational transport unit (Echelon Operationnel des Transports - EOT) of IPSN (Institute for Nuclear Protection and Safety). To guarantee en efficient protection of transport operations, the various following means are provided for: -specialized transport means; - devices for real time tracking of road vehicles; - administrative authorization and declaration procedures; -intervention capacities in case of sabotage... This set of technical means and administrative measures is completed by the existence of a body of inspectors who may control every step of the operations. (authors). 3 tabs

    1987-01-01

    This Greenpeace report shows: nuclear materials transport is an extremely hazardous business. There is no safe protection against accidents, kidnapping, or sabotage. Any moment of a day, at any place, a nuclear transport accident may bring the world to disaster, releasing plutonium or radioactive fission products to the environment. Such an event is not less probable than the MCA at Chernobyl. The author of the book in hand follows the secret track of radioactive materials around the world, from uranium mines to the nuclear power plants, from reprocessing facilities to the waste repositories. He explores the routes of transport and the risks involved, he gives the names of transport firms and discloses incidents and carelessness, tells about damaged waste drums and plutonium that 'disappeared'. He also tells about worldwide, organised resistance to such nuclear transports, explaining the Greenpeace missions on the open sea, or the 'day X' operation at the Gorleben site, informing the reader about protests and actions for a world freed from the threat of nuclear energy.

    The present paper investigates the parameters which may have effects on the safety of nuclear materials and other radioactive sources used in peaceful applications of atomic energy. The emergency response planning in such situations are also indicated. In synergy with nuclear safety measures, an approach is developed in this study for risk prevention. It takes into consideration the collective implementation of measures of nuclear material accounting and control, physical protection and monitoring of such strategic and dangerous materials in an integrated and coordinated real-time mode at a nuclear or radiation facility and in any time

    Termination of safeguards ends requirements of Nuclear Material Control and Accountability (MC and A) and thereby removes the safeguards basis for applying physical protection requirements for theft and diversion of nuclear material, providing termination requirements are met as described. Department of Energy (DOE) M 470.4 6 (Nuclear Material Control and Accountability [8/26/05]) stipulates: 1. Section A, Chapter I (1)( q) (1): Safeguards can be terminated on nuclear materials provided the following conditions are met: (a) 'If the material is special nuclear material (SNM) or protected as SNM, it must be attractiveness level E and have a measured value.' (b) 'The material has been determined by DOE line management to be of no programmatic value to DOE.' (c) 'The material is transferred to the control of a waste management organization where the material is accounted for and protected in accordance with waste management regulations. The material must not be collocated with other accountable nuclear materials.' Requirements for safeguards termination depend on the safeguards attractiveness levels of the material. For attractiveness level E, approval has been granted from the DOE Idaho Operations Office (DOE ID) to Battelle Energy Alliance, LLC (BEA) Safeguards and Security (S and S). In some cases, it may be necessary to dispose of nuclear materials of attractiveness level D or higher. Termination of safeguards for such materials must be approved by the Departmental Element (this is the DOE Headquarters Office of Nuclear Energy) after consultation with the Office of Security.

  1. Introduction to nuclear material safeguards

    International Nuclear Information System (INIS)

    Kuroi, Hideo

    1986-01-01

    This article is aimed at outlining the nuclear material safeguards. The International Atomic Energy Agency (IAEA) was established in 1957 and safeguards inspection was started in 1962. It is stressed that any damage resulting from nuclear proliferation would be triggered by a human intentional act. Various measures have been taken by international societies and nations, of which the safeguards are the only means which relay mainly on technical procedures. There are two modes of diversing nuclear materials to military purposes. One would be done by national intension while the other by indivisulas or expert groups, i.e., sub-national intention. IAEA is responsible for the prevention of diversification by nations, for which the international safeguards are being used. Measures against the latter mode of diversification are called nuclear protection, for which each nation is responsible. The aim of the safeguards under the Nonproliferation Treaty is to detect the diversification of a significant amount of nuclear materials from non-military purposes to production of nuclear explosion devices such as atomic weapons or to unidentified uses. Major technical methods used for the safeguards include various destructive and non-destructive tests as well as containment and monitoring techniques. System techniques are to be employed for automatic containment and monitoring procedures. Appropriate nuclear protection system techniques should also be developed. (Nogami, K.)

  2. Management of Global Nuclear Materials for International Security

    International Nuclear Information System (INIS)

    Isaacs, T; Choi, J-S

    2003-01-01

    Nuclear materials were first used to end the World War II. They were produced and maintained during the cold war for global security reasons. In the succeeding 50 years since the Atoms for Peace Initiative, nuclear materials were produced and used in global civilian reactors and fuel cycles intended for peaceful purposes. The Nonproliferation Treaty (NPT) of 1970 established a framework for appropriate applications of both defense and civilian nuclear activities by nuclear weapons states and non-nuclear weapons states. As global inventories of nuclear materials continue to grow, in a diverse and dynamically changing manner, it is time to evaluate current and future trends and needed actions: what are the current circumstances, what has been done to date, what has worked and what hasn't? The aim is to identify mutually reinforcing programmatic directions, leading to global partnerships that measurably enhance international security. Essential elements are material protection, control and accountability (MPC and A) of separated nuclear materials, interim storage, and geologic repositories for all nuclear materials destined for final disposal. Cooperation among key partners, such as the MPC and A program between the U.S. and Russia for nuclear materials from dismantled weapons, is necessary for interim storage and final disposal of nuclear materials. Such cooperative partnerships can lead to a new nuclear regime where a complete fuel cycle service with fuel leasing and spent fuel take-back can be offered to reactor users. The service can effectively minimize or even eliminate the incentive or rationale for the user-countries to develop their indigenous enrichment and reprocessing technologies. International cooperation, supported by governments of key countries can be best to facilitate the forum for formation of such cooperative partnerships

    1979-01-01

    Full text: The science of chemical thermodynamics has substantially contributed to the understanding of the many problems encountered in nuclear and reactor technology. These problems include reaction of materials with their surroundings and chemical and physical changes of fuels. Modern reactor technology, by its very nature, has offered new fields of investigations for the scientists and engineers concerned with the design of nuclear fuel elements. Moreover, thermodynamics has been vital in predicting the behaviour of new materials for fission as well as fusion reactors. In this regard, the Symposium was organized to provide a mechanism for review and discussion of recent thermodynamic investigations of nuclear materials. The Symposium was held in the Juelich Nuclear Research Centre, at the invitation of the Government of the Federal Republic of Germany. The International Atomic Energy Agency has given much attention to the thermodynamics of nuclear materials, as is evidenced by its sponsorship of four international symposia in 1962, 1965, 1967, and 1974. The first three meetings were primarily concerned with the fundamental thermodynamics of nuclear materials; as with the 1974 meeting, this last Symposium was primarily aimed at the thermodynamic behaviour of nuclear materials in actual practice, i.e., applied thermodynamics. Many advances have been made since the 1974 meeting, both in fundamental and applied thermodynamics of nuclear materials, and this meeting provided opportunities for an exchange of new information on this topic. The Symposium dealt in part with the thermodynamic analysis of nuclear materials under conditions of high temperatures and a severe radiation environment. Several sessions were devoted to the thermodynamic studies of nuclear fuels and fission and fusion reactor materials under adverse conditions. These papers and ensuing discussions provided a better understanding of the chemical behaviour of fuels and materials under these

    An automated state system of accounting for nuclear materials data was established in Czechoslovakia in 1979. A file was compiled of 12 programs in the PL/1 language. The file is divided into four groups according to logical associations, namely programs for data input and checking, programs for handling the basic data file, programs for report outputs in the form of worksheets and magnetic tape records, and programs for book inventory listing, document inventory handling and materials balance listing. A similar automated system of nuclear fuel inventory for a light water reactor was introduced for internal purposes in the Institute of Nuclear Research (UJV). (H.S.)

    1991-11-01

    A new section, 10 CFR 74.33, has been added to the material control and accounting (MC ampersand A) requirements of 10 CFR Part 74. This new section pertains to US Nuclear Regulatory Commission (NRC)-licensed uranium enrichment facilities that are authorized to produce and to possess more than one effective kilogram of special nuclear material (SNM) of low strategic significance. The new section is patterned after 10 CFR 74.31, which pertains to NRC licensees (other than production or utilization facilities licensed pursuant to 10 CFR Part 50 and 70 and waste disposal facilities) that are authorized to possess and use more than one effective kilogram of unencapsulated SNM of low strategic significance. Because enrichment facilities have the potential capability of producing SNM of moderate strategic significance and also strategic SNM, certain performance objectives and MC ampersand A system capabilities are required in 10 CFR 74.33 that are not contained in 10 CFR 74.31. This document recommends to the NRC information that the licensee or applicant should provide in the fundamental nuclear material control (FNMC) plan. This document also describes methods that should be acceptable for compliance with the general performance objectives. While this document is intended to cover various uranium enrichment technologies, the primary focus at this time is gas centrifuge and gaseous diffusion

    The history of safeguards is traced from the first session of the United Nations Atomic Energy Commission in 1946, through the various stages of the IAEA safeguard system for nuclear materials and to the initiation of the Treaty on the Non-proliferation of Nuclear Weapons in 1968. The role of the IAEA under the treaty is discussed. The structure and content of safeguards agreements in connection with the treaty were laid down and the objective of safeguards clearly defined. The methods of verification by the IAEA of the facility operator's material accountancy through inspection and statistical analysis and evaluation of 'material unaccounted for' are explained. The extent to which the IAEA may make use of the State's system of accounting and control of nuclear materials is considered. Reference is also made to the question of protection against theft and sabotage. Finally the scope of safeguards work for the next 15 years is forecast. (U.K.)

  17. Safeguards for nuclear material transparency monitoring

    International Nuclear Information System (INIS)

    MacArthur, D.A.; Wolford, J.K.

    1999-01-01

    The US and the Russian Federation are currently engaged in negotiating or implementing several nuclear arms and nuclear material control agreements. These involve placing nuclear material in specially designed containers within controlled facilities. Some of the agreements require the removal of nuclear components from stockpile weapons. These components are placed in steel containers that are then sealed and tagged. Current strategies for monitoring the agreements involve taking neutron and gamma radiation measurements of components in their containers to monitor the presence, mass, and composition of plutonium or highly enriched uranium, as well as other attributes that indicate the use of the material in a weapon. If accurate enough to be useful, these measurements will yield data containing information about the design of the weapon being monitored. In each case, the design data are considered sensitive by one or both parties to the agreement. To prevent the disclosure of this information in a bilateral or trilateral inspection scenario, so-called information barriers have evolved. These barriers combine hardware, software, and procedural safeguards to contain the sensitive data within a protected volume, presenting to the inspector only the processed results needed for verification. Interlocks and volatile memory guard against disclosure in case of failure. Implementing these safeguards requires innovation in radiation measurement instruments and data security. Demonstrating their reliability requires independent testing to uncover any flaws in design. This study discusses the general problem and gives a proposed solution for a high resolution gamma ray detection system. It uses historical examples to illustrate the evolution of other successful systems

    International Nuclear Information System (INIS)

    Beaman, M.; Beckers, J.; Boella, M.

    2001-01-01

    Full text: Some protagonists of the nuclear industry suggest that MOX fuel fabrication plants are awash with nuclear materials which cannot be adequately safeguarded and that materials 'stuck in the plant' could conceal clandestine diversion of plutonium. In Europe the real situation is quite different: nuclear operators have gone to considerable efforts to deploy effective systems for safety, security, quality and nuclear materials control and accountancy which provide detailed information. The safeguards authorities use this information as part of the safeguards measures enabling them to give safeguards assurances for MOX fuel fabrication plants. This paper focuses on the issue of hold-up: definition of the hold-up and of the so-called 'hidden inventory'; measures implemented by the plant operators, from design to day to day operations, for minimising hold-up and 'hidden inventory'; plant operators' actions to manage the hold-up during production activities but also at PIT/PIV time; monitoring and management of the 'hidden inventory'; measures implemented by the safeguards authorities and inspectorate for verification and control of both hold-up and 'hidden inventory'. The examples of the different plant specific experiences related in this paper reveal the extensive experience gained in european MOX fuel fabrication plants by the plant operators and the safeguards authorities for the minimising and the control of both hold-up and 'hidden inventory'. MOX fuel has been fabricated in Europe, with an actual combined capacity of 2501. HM/year subject, without any discrimination, to EURATOM Safeguards, for more than 30 years and the total output is, to date, some 1000 t.HM. (author)

    The proliferation of nuclear weapons, along with the technical knowledge and materials needed to make these weapons, is an enduring problem of international urgency. Current international nuclear nonproliferation efforts are aimed at deterring, detecting, and responding to proliferation of weapons of mass destruction. These safeguards efforts are being implemented by applying preeminent science and technology to the management and control of nuclear materials. By strengthening systems of nuclear material protection, control, and accountability (MPC and A), one can reduce the threat of nuclear weapons proliferation. Two major programs of international cooperation are now underway to achieve this goal. The first is between the US Department of Energy (DOE) and the Institutes of the Russian Federation (Laboratory-to-Laboratory Program), and the second is between the US Government and Governments of the former Soviet Republics (Government-to-Government Program). As part of these programs, the DOE is working with facilities to assist them in implementing computerized MPC and A systems. This work is a collaboration between computer scientists and safeguards experts in both the US and the new Republics. The US is making available technology and expertise to enable Russian experts to build on computerized MPC and A software developed in the US. This paper describes the joint efforts of these international teams to develop sophisticated computerized MPC and A systems using modern computer hardware and software technology. These systems are being customized to meet the site-specific needs of each facility

  20. Supply of nuclear materials

    1959-07-15

    Any large-scale atomic energy programme is inherently dependent on the availability of materials that can be used as fuel in reactors, and the International Atomic Energy Agency, at its inception, was intended to act as a bank for the flow of materials between Member States. According to its Statute, one of its primary functions is to provide materials 'to meet the needs of research on, and development and practical application of, atomic energy for peaceful purposes, including the production of electric power, with due consideration for the needs of the under-developed areas of the world'. If the Agency is to fulfil its Statutory function, it would be essential for it to have not only some ready sources of supply, but also an established framework of general terms and conditions on which it could secure the supplies. The latter would eliminate the need for going through elaborate procedural formalities whenever the Agency receives a new request for materials. Such a framework has now been established with the signing of broad agreements with three countries which had offered to supply various quantities of special fissionable materials to the Agency. These agreements, signed in Vienna on 11 May 1959, with the USSR, the UK and the USA, lay down the basic terms and conditions on which these three countries will make nuclear materials available when needed by the Agency. The USSR has agreed to make available to the Agency 50 kg of uranium-235, the UK 20 kg and the USA 5 000 kg. The material will be supplied in the form of enriched uranium in any concentration up to 20 per cent; the amounts mentioned relate to the 235-isotope content of the materials. The UK and the USA have agreed that the parties to a particular supply agreement may decide on higher enrichment of uranium to be used for research reactors, material testing reactors or for other research purposes. The USA has also agreed to make available to the Agency such additional supplies as would match in amount

    A code for the computation of the global neutron distribution in the three-dimensional hexagonal-z geometry and multi-group diffusion approximation was developed at BN-350 as the main part of the BN-350 accounting for and control of nuclear material software system. This software system includes: the model for stationary distributions of neutrons; the model to calculate isotope compositions changing; the model of refueling operations; To develop this system next two principal problems were solved: to make a micro cross sections library for all nuclides for the BN-350 reactor core; to develop the code for the computation of the global neutron distribution. To solve first task the twenty-six-energy-groups micro cross sections library for more than seventy nuclides was produced. To solve second task the three-dimensional hexagonal-z geometry and multi-group diffusion approximation code was developed. This code (HEX-Z-DMG) was based on the solution of the multi groups diffusion equation using the standard net approach. The series of calculations was performed in the twenty-six-energy-groups representation using this code. We compared eigenvalues (k eff ), a worth added during refueling operations, spatial and energy-group-dependent neutron flux distributions with results of calculation using other code (DIF3D). After the series of these calculations we can say that the HEX-Z-DMG code is well established to use as the part of the BN-350 accounting for and control of nuclear material software system.

  3. Thermodynamics of nuclear materials

    International Nuclear Information System (INIS)

    1962-01-01

    The first session of the symposium discussed in general the thermodynamic properties of actinides, including thorium, uranium and Plutonium which provide reactor fuel. The second session was devoted to applications of thermodynamic theory to the study of nuclear materials, while the experimental techniques for the determination of thermodynamic data were examined at the next session. The thermodynamic properties of alloys were considered at a separate session, and another session was concerned with solids other than alloys. Vaporization processes, which are of special interest in the development of high-temperature reactors, were discussed at a separate session. The discussions on the methods of developing the data and ascertaining their accuracy were especially useful in highlighting the importance of determining whether any given data are reliable before they can be put to practical application. Many alloys and refractory materials (i. e. materials which evaporate only at very high temperatures) are of great importance in nuclear technology, and some of these substances are extremely complex in their chemical composition. For example, until recently the phase composition of the oxides of thorium, uranium and plutonium had been only very imperfectly understood, and the same was true of the carbides of these elements. Recent developments in experimental techniques have made it possible to investigate the phase composition of these complex materials as well as the chemical species of these materials in the gaseous phase. Recent developments in measuring techniques, such as fluorine bomb calorimetry and Knudsen effusion technique, have greatly increased the accuracy of thermodynamic data

    History can be a very dull subject if it relates to events which have long since lost their relevance. The factors which led to the creation of the International Atomic Energy Agency (IAEA), however, are as important and relevant today as they were when the Agency was first created. Without understanding these factors it is impossible to realise how important the Agency is in the present world or to understand some of the controversies surrounding its future. Central to these controversies is the question of how best to promote the international transfer of nuclear technology without contributing further to the problem of proliferating nuclear explosives or explosive capabilities. One effective means is to subject nuclear materials (see accompanying article in box), which forms the basic link between the manufacture of nuclear explosives and nuclear power generation, to international safeguards. This was realized very early in the development of nuclear power and was given greater emphasis following the deployment of the first two atomic bombs towards the end of World War II. (author)

    1982-03-01

    In any processing, manufacturing, or active storage facility it is impractical to assume that any physical security system can prevent the diversion of Special Nuclear Material (SNM). It is, therefore, the responsibility of any DOE Contractor, Licensee, or other holder of SNM to provide assurance that loss or diversion of a significant quantity of SNM is detectable. This ability to detect must be accomplishable within a reasonable time interval and can be accomplished only by taking physical inventories. The information gained and decisions resulting from these inventories can be no better than the SNM accounting system and the quality of measurements performed for each receipt, removal and inventory. Inventories interrupt processing or production operations, increase personnel exposures, and can add significantly to the cost of any operation. Therefore, realistic goals for the inventory must be defined and the relationship of the inherent parameters used in its validation be determined. Purpose of this document is to provide a statement of goals and a plan of action to achieve them

    For over ten years SSC RF-IPPE, together with the US DOE National Laboratories, has been working on implementing automated control and accountability methods for nuclear materials and other items. Initial efforts to use adhesive bar codes or ones printed (painted) onto metal revealed that these methods were inconvenient and lacked durability under operational conditions. For NM disk applications in critical stands, there is the additional requirement that labels not affect the neutron characteristics of the critical assembly. This is particularly true for the many stainless-steel clad disks containing highly enriched uranium (HEU) and plutonium that are used at SSC RF-IPPE for modeling nuclear power reactors. In search of an alternate method for labeling these disks, we tested several technological options, including laser marking and two-dimensional codes. As a result, the method of laser coloring was chosen in combination with Data Matrix ECC200 symbology. To implement laser marking procedures for the HEU disks and meet all the nuclear material (NM) handling standards and rules, IPPE staff, with U.S. technical and financial support, implemented an automated laser marking system; there are also specially developed procedures for NM movements during laser marking. For the laser marking station, a Zenith 10F system by Telesis Technologies (10 watt Ytterbium Fiber Laser and Merlin software) is used. The presentation includes a flowchart for the automated system and a list of specially developed procedures with comments. Among other things, approaches are discussed for human-factor considerations. To date, markings have been applied to numerous steel-clad HEU disks, and the work continues. In the future this method is expected to be applied to other MC and A items.

    1994-01-01

    Recent Department of Energy (DOE) initiatives have given Departmental nuclear facilities the opportunity to take more credit for certain existing safeguards and security systems in determining operational program protection requirements. New policies and guidance are coupled with these initiatives to enhance systems performance in a cost effective and efficient manner as well as to reduce operational costs. The application of these methods and technologies support safety, the reduction of personnel radiation exposure, emergency planning, and inspections by international teams. This discussion will review guidance and policies that support advanced systems and programs to decrease lifetime operational costs without increasing risk

    The project: Development of the nuclear materials (NM) control and accountancy system model on the example of the SCP Radiochemical Plant (RCP) has been fulfilled by the Siberian Chemical Plant in collaboration with a number of organization since October 1992 through October 1996. One of the key goals of the project was the use of new criteria and approaches to NM control and accounting, including step-by-step implementation for all the NM flows measurement principles. The work on project has resulted in the development of the model for NM control and accountancy system at RCP. When designing the model, the single RCP balance area on uranium and plutonium was broken down to four NM balance areas. The model developed within the project is being implemented in a few ways: introduction of innovative NM measurement techniques, working out regulatory documents, adaptation of computers for control and accountancy. An aim to secure safety in the most problematic area MBA-2 (plutonium dioxide production) transition to the real-time cannot be resolved without implementation of computerized system of NM control and accountancy [ru

    Argentina and Brazil began its activities in the nuclear area about the same time, in the 50 century past. The existence of an international nuclear nonproliferation treaty-TNP-seen by Brazil and Argentina as discriminatory and prejudicial to the interests of the countries without nuclear weapons, led to the need for a common system of control of nuclear material between the two countries to somehow provide assurances to the international community of the exclusively peaceful purpose of its nuclear programs. The creation of a common system, assured the establishment of uniform procedures to implement safeguards in Argentina and Brazil, so the same requirements and safeguards procedures took effect in both countries, and the operators of nuclear facilities began to follow the same rules of control of nuclear materials and subjected to the same type of verification and control. On July 18, 1991, the Bilateral Agreement for the Exclusively Peaceful Use of Nuclear Energy created a binational body, the Argentina-Brazil Agency for Accounting and Control of Nuclear Materials-ABACC-to implement the so-called Common System of Accounting and Control of Nuclear materials - SCCC. The deal provided, permanently, a clear commitment to use exclusively for peaceful purposes all material and nuclear facilities under the jurisdiction or control of the two countries. The Quadripartite Agreement, signed in December of that year, between the two countries, ABACC and IAEA completed the legal framework for the implementation of comprehensive safeguards system. The 'model ABACC' now represents a paradigmatic framework in the long process of economic, political, technological and cultural integration of the two countries. Argentina and Brazil were able to establish a guarantee system that is unique in the world today and that consolidated and matured over more than twenty years, has earned the respect of the international community.

  11. New challenges in nuclear material detection

    2002-01-01

    Full text: Even before the attacks of September 11, 2001 the International Safeguards community recognized the magnitude of the threat posed by illicit trafficking of nuclear materials and the need for enhanced physical protection. For the first time, separate sessions on illicit trafficking and physical protection of nuclear materials were included in the IAEA Safeguards Symposium. In the aftermath of September 11, it is clear that the magnitude of the problem and the urgency with which it must be addressed will be a significant driver for advanced nuclear materials detection technologies for years to come. Trafficking in nuclear material and other radioactive sources is a global concern. According to the IAEA Illicit Trafficking Database Program, there have been confirmed cases in more than 40 countries and the number of cases per year have nearly doubled since 1996. The challenge of combating nuclear terrorism also brings with it many opportunities for the development of new tools and new approaches. In addition to the traditional gamma-ray imaging, spectrometry and neutron interrogation, there is a need for smaller, smarter, more energy-efficient sensors and sensor systems for detecting and tracking threats. These systems go by many names - correlated sensor networks, wide-area tracking systems, sensor or network fabrics - but the concept behind them is the same. Take a number of wireless sensors and tie them together with a communications network, develop a scheme for fusing the data and make the system easy to deploy. This paper will present a brief survey of nuclear materials detection capability, and discuss some advances in research and development that are particularly suited for illicit trafficking, detection of shielded highly enriched uranium, and border security.

    This paper describes general safeguards research being undertaken by the United States Nuclear Regulatory Commission. Efforts to improve the ability of United States licensed plants to contend with the perceived threat of covert material theft are emphasized. The framework for this improvement is to break down the internal control and accounting system into subsystems to achieve material isolation, inventory control, inventory characterization, and inventory containment analysis. A general programme is outlined to develop and evaluate appropriate mechanisms, integrate selected mechanisms into subsystems, and evaluate the subsystems in the context of policy requirements.

    The Nevada Test Site (NTS) has transitioned from its historical role of weapons testing to a broader role that is focused on being a solution to multiple National Nuclear Security Administration (NNSA) challenges and opportunities with nuclear materials for the nation. NTS is supporting other NNSA sites challenged with safe nuclear materials storage and disposition. NNSA, with site involvement, is currently transforming the nuclear stockpile and supporting infrastructure to meet the 2030 vision. Efforts are under way to make the production complex smaller, more consolidated, and more modern. With respect to the nuclear material stockpile, the NNSA sites are currently reducing the complex nuclear material inventory through dispositioning and consolidating nuclear material. This includes moving material from other sites to NTS. State-of-the-art nuclear material management and control practices at NTS are essential for NTS to ensure that these new activities are accomplished in a safe, secure, efficient, and environmentally responsible manner. NTS is aggressively addressing this challenge

    In nuclear facilities, the nuclear material control is one of the most important activities. The Brazilian National Commission of Nuclear Energy (CNEN) and the International Atomic Energy Agency (IAEA), when inspecting routinely, regards the data provided as a major safety factor. Having a control system of nuclear material that allows the amount and location of the various items to be inspected, at any time, is a key factor today. The objective of this work was to enhance the existing system using a more friendly platform of development, through the VisualBasic programming language (Microsoft Corporation), to facilitate the operation team of the reactor IEA-R1 Reactor tasks, providing data that enable a better and prompter control of the IEA-R1 nuclear material. These data have allowed the development of papers presented at national and international conferences and the development of master's dissertations and doctorate theses. The software object of this study was designed to meet the requirements of the CNEN and the IAEA safeguard rules, but its functions may be expanded in accordance with future needs. The program developed can be used in other reactors to be built in the country, since it is very practical and allows an effective control of the nuclear material in the facilities. (author)

    The SS Acountability System was designed to provide accountability of all SS materials by unit identification and grams. The existing system is a gram-accountable system. The new system was designed to incorporate unit identification into an ADP (Automated Data Processing) System. It also records all transactions performed against a particular unit of accountable material. The high volume of data is input via CRT terminals. Input data will consist of the following: source of the material (its unit identification), amount of material being moved, isotopic content, type of material, Health Physics number of the person moving the material, account number from which the material is being moved, unit identification of the material being moved (if all material is not moved), Health Physics number of the person receiving the material, account number to which material is being moved, and acceptance of the material by the receiver. A running inventory of all material is kept. At the end of the month the physical inventory will be compared to the data base and all discrepancies reported. Since a complete history of transactions has been kept, the source and cause for any discrepancies should be easily located. Discrepancies are held to a minimum since errors are detected before entrance into the data base. The system will also furnish all reports necessary to control SS Accountability. These reports may be requested at any time via an accountability master terminal

  18. Modernizing computerized nuclear material accounting systems

    1995-01-01

    DOE Orders and draft orders for nuclear material control and accountability address a complete material control and accountability (MC and A) program for all DOE contractors processing, using, or storing nuclear materials. A critical element of an MC and A program is the accounting system used to track and record all inventories of nuclear material and movements of materials in those inventories. Most DOE facilities use computerized accounting systems to facilitate the task of accounting for all their inventory of nuclear materials. Many facilities still use a mixture of a manual paper system with a computerized system. Also, facilities may use multiple systems to support information needed for MC and A. For real-time accounting it is desirable to implement a single integrated data base management system for a variety of users. In addition to accountability needs, waste management, material management, and production operations must be supported. Information in these systems can also support criticality safety and other safety issues. Modern networked microcomputers provide extensive processing and reporting capabilities that single mainframe computer systems struggle with. This paper describes an approach being developed at Los Alamos to address these problems

  19. Bar code usage in nuclear materials accountability

    1983-01-01

    The age old method of physically taking an inventory of materials by listing each item's identification number has lived beyond its usefulness. In this age of computerization, which offers the local grocery store a quick, sure, and easy means to inventory, it is time for nuclear materials facilities to automate accountability activities. The Oak Ridge Y-12 Plant began investigating the use of automated data collection devices in 1979. At that time, bar code and optical-character-recognition (OCR) systems were reviewed with the purpose of directly entering data into DYMCAS (Dynamic Special Nuclear Materials Control and Accountability System). Both of these systems appeared applicable; however, other automated devices already employed for production control made implementing the bar code and OCR seem improbable. However, the DYMCAS was placed on line for nuclear material accountability, a decision was made to consider the bar code for physical inventory listings. For the past several months a development program has been underway to use a bar code device to collect and input data to the DYMCAS on the uranium recovery operations. Programs have been completed and tested, and are being employed to ensure that data will be compatible and useful. Bar code implementation and expansion of its use for all nuclear material inventory activity in Y-12 is presented

    In order to solve different problems of chemical analysis in the fields of nuclear industry and research, a Quantometer is used with a high number of channels. A detailed study to choose the more suitable spectral lines is described. The different channels have been distributed into two programs to allow the analysis of high and low concentrations. The Quantometer is being applied successfully to analyse soils, plant ashes, rocks and ores, uranium and its compounds, zirconium, graphite, alloys and other nuclear materials. (Author) 6 refs.

    ElBaradei, M.

    2001-01-01

    The main topics dealt with the ensuring of an effective, universal and adequately financed system for the verification of nuclear non-proliferation, namely as follows: Effectiveness of the system; Participation in the system ; Financing of the system; Making Progress in Nuclear Arms Control; Protection Against Nuclear Terrorism. In the Safeguards Implementation Report (SIR) for 2000, the Agency was able to conclude that for all 140 states with safeguards agreements in place the nuclear material and other items placed under safeguards remained in peaceful nuclear activities or were otherwise adequately accounted for. The Agency currently safeguards over 900 facilities in 70 countries on a regular safeguards budget of approximately US $80 million per year. Turning to the major recent challenge, protection against nuclear terrorism, the IAEA has long been active in encouraging States to make security an integral part of the management of their nuclear programmes. The recent attacks in the United States were, however, a wake-up call to all that more can and must be done. In the week immediately following the tragedy, the IAEA General Conference adopted a resolution which requested a thorough review of Agency activities and programmes relevant to preventing acts of nuclear terrorism

    1994-02-01

    The Office of Weapons and Materials Planning (DP-27) requested the Planning Support Group (PSG) at the Savannah River Site to help coordinate a Departmental complex-wide nuclear materials storage study. This study will support the development of management strategies and plans until Defense Programs' Complex 21 is operational by DOE organizations that have direct interest/concerns about or responsibilities for nuclear material storage. They include the Materials Planning Division (DP-273) of DP-27, the Office of the Deputy Assistant Secretary for Facilities (DP-60), the Office of Weapons Complex Reconfiguration (DP-40), and other program areas, including Environmental Restoration and Waste Management (EM). To facilitate data collection, a questionnaire was developed and issued to nuclear materials custodian sites soliciting information on nuclear materials characteristics, storage plans, issues, etc. Sites were asked to functionally group materials identified in DOE Order 5660.1A (Management of Nuclear Materials) based on common physical and chemical characteristics and common material management strategies and to relate these groupings to Nuclear Materials Management Safeguards and Security (NMMSS) records. A database was constructed using 843 storage records from 70 responding sites. The database and an initial report summarizing storage issues were issued to participating Field Offices and DP-27 for comment. This report presents the background for the Storage Study and an initial, unclassified summary of storage issues and concerns identified by the sites

  5. Illicit diversion of nuclear materials

    International Nuclear Information System (INIS)

    Bett, F.L.

    1975-08-01

    This paper discusses the means of preventing illegal use of nuclear material by terrorists or other sub-national groups and by governments. With respect to sub-national groups, it concludes that the preventive measures of national safeguards systems, when taken together with the practical difficulties of using nuclear material, would make the diversion and illegal use of nuclear material unattractive in comparison with other avenues open to these groups to attain their ends. It notes that there are only certain areas in the nuclear fuel cycle, e.g. production of some types of nuclear fuel embodying highly enriched uranium and shipment of strategically significant nuclear material, which contain material potentially useful to these groups. It also discusses the difficult practical problems, e.g. coping with radiation, which would face the groups in making use of the materials for terrorist purposes. Concerning illegal use by Governments, the paper describes the role of international safeguards, as applied by the International Atomic Energy Agency, and the real deterrent effect of these safeguards which is achieved through the requirements to maintain comprehensive operating records of the use of nuclear material and by regular inspections to verify these records. The paper makes the point that Australia would not consider supplying nuclear material unless it were subject to international safeguards. (author)

    Nuclear safety accidents directly affect human health but nuclear security incidents indirectly influence human, which demonstrates the reason why security receives less attention. However, it is acknowledged that nuclear terrorism is indeed one of the most dreadful threat humanity faces. As part of strengthening nuclear security as well as nonproliferation to response to the threat, we need a better understanding of the nuclear material which needs to be safe under the objective of nuclear security. In reality, practitioners implement safeguards and physical protection in compliance with the regulation text in domestic legislation. Thus, it is important to specify nuclear material clearly in law for effective implementation. Therefore, the definition of terminology related to nuclear material is explored herein, within the highest-level legislation on the safeguards and physical protection. First the definition in Korean legislation is analyzed. Then, so as to suggest some improvements, other international efforts are examined and some case studies are conducted on other states which have similar level of nuclear technology and industry to Korea. Finally, a draft of definition on nuclear material in perspective of nuclear nonproliferation and security is suggested based on the analysis below. The recommendation showed the draft nuclear material definition in nuclear control. The text will facilitate the understanding of nuclear material in the context of nuclear nonproliferation and security. It might provide appropriate provision for future legislation related to nuclear nonproliferation and security. For effective safeguards and physical protection measures, nuclear material should be presented with in a consistent manner as shown in the case of United Kingdom. It will be much more helpful if further material engineering studies on each nuclear material are produced. Multi-dimensional approach is required for the studies on the degree of efforts to divert

    Fernández Moreno, Sonia

    2011-01-01

    Cooperation between the IAEA, States and regional organizations is increasingly important to ensure effective accountancy and control of nuclear material in peaceful uses. The IAEA, SAGSI2 and institutions such INMM3 and ESARDA4 have recognized the relevance and the evolving role that SSAC5 and regional organizations play to this aim. In this context, it is important to take steps to ensure the effectiveness of the system and the optimal level of relationship between these organizations so as to maximize the benefits for each party, particularly in those cases where well developed systems exist. Moreover, expansion of nuclear energy requires concerted efforts towards building competence in safeguards in all relevant States. This is also important with respect to other aspects of nonproliferation. In this scenario there is agreement on the need to have effective state organizations that fulfill international safeguards and other security obligations. However, the roles and duties of SSAC and the possible scope of cooperation between the IAEA and SSAC are still under evolution. This paper discusses possible ways and means to build competence in safeguards and how the international community could be more proactive in establishing a framework including the various dimensions of the cooperation in safeguards and other security matters between all parties concerned. The establishment of a forum and a network of interested parties under the auspice of interested organizations could be one mechanism to exchange best practices and experiences. (authors)

    1995-12-01

    This report documents a standard format suggested by the NRC for use in preparing fundamental nuclear material control (FNMC) plans as required by the Low Enriched Uranium Reform Amendments (10CFR 74.31). This report also describes the necessary contents of a comprehensive plan and provides example acceptance criteria which are intended to communicate acceptable means of achieving the performance capabilities of the Reform Amendments. By using the suggested format, the licensee or applicant will minimize administrative problems associated with the submittal, review and approval of the FNMC plan. Preparation of the plan in accordance with this format Will assist the NRC in evaluating the plan and in standardizing the review and licensing process. However, conformance with this guidance is not required by the NRC. A license applicant who employs a format that provides a equal level of completeness and detail may use their own format. This document is also intended for providing guidance to licensees when making revisions to their FNMC plan

    2015-01-01

    In its first part, this report presents the nuclear sector as a sensitive sector under strict surveillance: a sector of critical importance (safety policy with its actors and its multi-level planning, a safety arrangement for the nuclear energy sector), a regulation specific to the nuclear sector, and specialised protection forces. It also addresses the issues of intrusions and over-flights (overview of intrusions, unsuitable penal repression, and new dimension of air safety due to the development of civil uses of drones). The next part comments the content of the bill proposition, and addresses the lack of a suitable penal regime for the protection of nuclear materials and of areas regarding defence. The scope of application of the bill proposition is discussed, as well as the applicable and additional penalties. A list of hearings is provided as well as non adopted amendments and a table proposing a comparison between different versions of the text

    An important program of research, called 'Generation IV' is currently developed at an international level to prepare the launching of reactors for the future. Its objective is to satisfy the growing needs in electric power within the framework for a sustainable development. One of the major aspects of this program is the search and the development for new nuclear materials containing fissile/fertile isotopes. Unfortunately, one realizes today that for many compounds considered to be used to manufacture these materials, there are no radio-toxicologic data, allowing to the occupational physicist to evaluate the real risk in the event of contaminations and to prescribe adapted therapeutic de-corporation. An emergency revival of 'workplace' studies, where are or will be handled these compounds or materials is mandatory. The lesson of the past showed that the prevision in radioprotection was rather difficult and that an experimental validation of the behaviour of hazardous heavy elements both in vitro and in vivo was necessary.

  12. Technologies for detection of nuclear materials

    International Nuclear Information System (INIS)

    DeVolpi, A.

    1996-01-01

    Detection of smuggled nuclear materials at transit points requires monitoring unknown samples in large closed packages. This review contends that high-confidence nuclear-material detection requires induced fission as the primary mechanism, with passive radiation screening in a complementary role. With the right equipment, even small quantities of nuclear materials are detectable with a high probability at transit points. The equipment could also be linked synergistically with detectors of other contrabond. For screening postal mail and packages, passive monitors are probably more cost-effective. When a suspicious item is detected, a single active probe could then be used. Until active systems become mass produced, this two-stage screening/interrogation role for active/passive equipment is more economic for cargo at border crossings. For widespread monitoring of nuclear smuggling, it will probably be necessary to develop a system for simultaneously detecting most categories of contraband, including explosives and illicit drugs. With control of nuclear materials at known storage sites being the first line of defense, detection capabilities at international borders could establish a viable second line of defense against smuggling

    2010-01-01

    Nuclear energy plays an important role in the development of the economy and is considered as a key element with regard to the growth of the world energy demand due to the limitation of other natural energy resources, its contribution to the protection of the environment and the reduction of CO 2 emission. Several countries, including some Arab countries, are planning to consider the nuclear option in the near future. To provide an assurance to the international community of the peaceful uses of nuclear energy, the International Atomic Energy Agency established legal tools, called Safeguards Agreements, to be accepted by every state willing to run nuclear programmes for peaceful purposes. The most important basis required by these agreements is the State System of Accounting for and Control of Nuclear Material, which plays a primary role for effective and efficient fulfilment of the state commitment with regard to the international safeguards agreements. The requirements for the set-up of a State System of Accounting for and Control , its role, its objectives and its fundamental elements are deeply presented. (author)

    The ability to tap the massive energy potential of nuclear fission was first developed as a weapon to end a terrible world war. Nuclear fission is also a virtually inexhaustible energy resource, and is the only energy supply in certain areas in Russia, Kazakhstan and elsewhere. The potential link between civilian and military applications has been and continues to be a source of concern. With the end of the Cold War, this issue has taken a dramatic turn. The U.S. and Russia have agreed to reduce their nuclear weapons stockpiles by as much as two-thirds. This will make some 100 tonnes of separated plutonium and 500 tonnes of highly enriched uranium available, in a form that is obviously directly usable for weapons. The total world inventory of plutonium is now around 1000 tonnes and is increasing at 60-70 tonnes per year. There is even more highly enriched uranium. Fortunately the correct answer to what to do with excess weapons material is also the most attractive. It should be used and reused as fuel for fast reactors. Material in use (particularly nuclear material) is very easy to monitor and control, and is quite unattractive for diversion. Active management of fissile materials not only makes a major contribution to economic stability and well-being, but also simplifies accountability, inspection and other safeguards processes; provides a revenue stream to pay for the necessary safeguards; and, most importantly, limits the prospective world inventory of plutonium to only that which is used and useful

    The need for highly qualified and well trained experts in the area of nuclear safeguards and non-proliferation has been emphasized at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors' meetings. To meet this need, the IAEA has developed a training programme dedicated to assisting Member States in building-up knowledge, skills and attitudes required for the sustainable establishment and maintenance of an effective State system of accounting for and control of nuclear material. The IAEA training programme in the area of nuclear safeguards and non-proliferation is designed for experts in governmental organizations, regulatory bodies, utilities and relevant industries and is provided on a regular basis at the regional and international level and, upon request, at the national level. It is based on training needs assessed, inter alia, during relevant IAEA advisory services and is updated periodically by applying the Systematic Approach to Training (SAT). In the framework of this human resources assistance programme, the IAEA also facilitates fellowship programmes for young professionals, regularly hosts the IAEA safeguards traineeship programme and supports safeguards related outreach activities organized by donor countries, universities or other institutions. This paper provides an overview of the IAEA's efforts in the area of nuclear safeguards and non-proliferation training and education, including assistance to Member States' initiatives and nuclear education networks, focusing on the development and delivery of nuclear safeguards training and academic courses. Further, it discusses the important role of IAEA advisory missions and other mechanisms that significantly contribute to the continuous improvement of the IAEA Member States training in the area of nuclear safeguards and non-proliferation. Finally, it outlines the forthcoming eLearning module on Safeguards that will complement the existing training

    Since the early nineties, illicit trafficking (IT) of nuclear materials and radioactive sources appeared as a new trend which raised the concern of the international community due to the grave consequences that would merge if these materials or radioactive sources fell into the hands of terrorist groups. However, by the end of the last century illicit trafficking of nuclear materials and radioactive sources lost its considerable salience, in spite of seizure of considerable amounts of 2 '3'5U (76% enrichment) in Bulgaria (May 1999) and also 235 U (30% enrichment) in Georgia (April 2000). Nevertheless, IT should be always considered as a continued and viable threat to the international community. Awareness of the problem should be developed and maintained among concerned circles as the first step towards combating illicit trafficking of nuclear materials and radioactive sources. Illicit trafficking of nuclear and radioactive materials needs serious consideration and proper attention by the governmental law enforcement authorities. Measures to combat with IT of nuclear material or radioactive sources should be effective in recovery, of stolen, removed or lost nuclear materials or radioactive sources due to the failure of the physical protection system or the State System Accounting and Control (SSAC) system which are normally applied for protecting these materials against illegal actions. Measures such as use of modern and efficient radiation monitoring equipment at the borders inspection points, is an important step in preventing the illicit trafficking of nuclear and radioactive materials across the borders. Also providing radiological training to specific personnel and workers in this field will minimize the consequences of a radiological attack in case of its occurrence. There is a real need to start to enter into cooperative agreements to strengthen borders security under the umbrella of IAEA to faster as an international cooperation in the illicit trafficking

    The Oak Ridge Y-12 Plant began investigating the use of automated data collection devices in 1979. At this time, bar code and optical-character-recognition (OCR) systems were reviewed with the purpose of directly entering data into DYMCAS (Dynamic Special Nuclear Materials Control and Accountability System). Both of these systems appeared applicable, however, other automated devices already employed for production control made implementing the bar code and OCR seem improbable. However, the DYMCAS was placed on line for nuclear material accountability, a decision was made to consider the bar code for physical inventory listings. For the past several months a development program has been underway to use a bar code device to collect and input data to the DYMCAS on the uranium recovery operations. Programs have been completed and tested, and are being employed to ensure that data will be compatible and useful. Bar code implementation and expansion of its use for all nuclear material inventory activity in Y-12 is presented

    Nuclear materials accounting and accounting systems at what have been DOE Production sites are evolving into management decision support tools. As the sites are moving into the mode of making decisions on how to disposition complex and varied nuclear material holdings, the need for complete and many times different information has never been greater. The artificial boundaries that have historically been established between what belongs in the classic material control and accountability (MC and A) records versus what goes into the financial, radiological control, waste, or decommissioning and decontamination records are being challenged. In addition, the tools historically used to put material into different categories such as scrap codes, composition codes, etc. have been found to be inadequate for the information needs of today. In order to be cost effective and even, more importantly to effectively manage -our inventories, the new information systems the authors design have to have the flexibility to serve many needs. In addition, those tasked with the responsibility of managing the inventories must also expand beyond the same artificial boundaries. This paper addresses some of the things occurring at the Savannah River Site to support the changing role of nuclear materials accounting

    This paper is a discussion of the use of available data in the performance of nuclear material (NM) safeguards. The discussion considers the various sources of data and system requirements for collecting and managing that data, and is preliminary concerned with domestic safeguards requirements such as those specified by the US Department of Energy. The preferred configuration for integrated data management does not necessarily require a single computer system; however, separate computerized systems with direct inter-system connections is preferred. Use of all relevant data NM accounting, NM control, physical protection, and non-safeguards) is necessary to assure the most effective protection for the NM inventories. Where direct exchange of data is not possible, a systematic program to implement indirect exchange is essential [ru

    This paper presents initial results from development of the induced-fission imaging technique, which can be used for the purpose of measuring or verifying the distribution of fissionable material in an unopened container. The technique is based on stimulating fissions in nuclear material with 14 MeV neutrons from an associated-particle deuterium-tritium (D-T) generator and counting the subsequent induced fast fission neutrons with an array of fast organic scintillation detectors. For each source neutron incident on the container, the neutron creation time and initial trajectory are known from detection of the associated alpha particle of the d + t → α + n reaction. Many induced fissions will lie along (or near) the interrogating neutron path, allowing an image of the spatial distribution of prompt induced fissions, and thereby fissionable material, to be constructed. A variety of induced-fission imaging measurements have been performed at Oak Ridge National Laboratory with a portable, low-dose D-T generator, including single-view radiographic measurements and three-dimensional tomographic measurements. Results from these measurements will be presented along with the neutron transmission images that have been performed simultaneously. This new capability may have applications to a number of areas in which there may be a need to confirm the presence or configuration of nuclear materials, such as nuclear material control and accountability, quality assurance, treaty confirmation, or homeland security applications.

    An apparatus for simulating special nuclear material is provided. The apparatus typically contains a small quantity of special nuclear material (SNM) in a configuration that simulates a much larger quantity of SNM. Generally the apparatus includes a spherical shell that is formed from an alloy containing a small quantity of highly enriched uranium. Also typically provided is a core of depleted uranium. A spacer, typically aluminum, may be used to separate the depleted uranium from the shell of uranium alloy. A cladding, typically made of titanium, is provided to seal the source. Methods are provided to simulate SNM for testing radiation monitoring portals. Typically the methods use at least one primary SNM spectral line and exclude at least one secondary SNM spectral line.

    In the spring of 1959 the well-read metallurgist would have noticed the first issue of an infant Journal, one dedicated to a unique and fast growing field of materials issues associated with nuclear energy systems. The periodical, Journal of Nuclear Materials (JNM), is now the leading publication in the field from which it takes its name, thriving beyond the rosiest expectations of its founders. The discipline is well into the second half-century. During that time much has been achieved in nuclear materials; the Journal provides the authoritative record of virtually all those accomplishments. These pages introduce the 500th volume, a significant measure in the world of publishing. The Editors reflect on the progress in the field and the role of this journal.

  7. IMPORTANCE OF MATERIAL BALANCES AND THEIR STATISTICAL EVALUATION IN RUSSIAN MATERIAL, PROTECTION, CONTROL AND ACCOUNTING

    International Nuclear Information System (INIS)

    Fishbone, L.G.

    1999-01-01

    While substantial work has been performed in the Russian MPC and A Program, much more needs to be done at Russian nuclear facilities to complete four necessary steps. These are (1) periodically measuring the physical inventory of nuclear material, (2) continuously measuring the flows of nuclear material, (3) using the results to close the material balance, particularly at bulk processing facilities, and (4) statistically evaluating any apparent loss of nuclear material. The periodic closing of material balances provides an objective test of the facility's system of nuclear material protection, control and accounting. The statistical evaluation using the uncertainties associated with individual measurement systems involved in the calculation of the material balance provides a fair standard for concluding whether the apparent loss of nuclear material means a diversion or whether the facility's accounting system needs improvement. In particular, if unattractive flow material at a facility is not measured well, the accounting system cannot readily detect the loss of attractive material if the latter substantially derives from the former

    The Federal Republic of Germany (FRG), the Russian Federation (RF) and the New Independent States (NIS) have been working closely together since 1992 in the field of physical protection. The success of this co-operative work is based on mutually beneficial agreements between corresponding FRG and RF ministries. The main working points of these agreements were a) a mutual exchange of information and experience, and b) assistance in developing licensing and regulatory procedures and guidelines, and c) physical upgrades to Russian nuclear facilities. The first two points have been established by holding seminars, workshops and by on-site instruction. Upgrades of RF nuclear installations, financed by the FRG were performed at: the Bochvar Institute in Moscow, the Kurchatov Institute in Moscow and the Mayak reactor plant in Chelyabinsk. This paper will outline the progress made to date and the GRS procedure for achieving successful co-operation with its RF and NIS counterparts. The major results of ten years cooperation will be shown. The following document describes the experiences gained during the evaluation of security reports by GRS as an external expert organisation in contract with the Supervisory Authorities. (authors)

    As part of a multifaceted approach to protecting its nuclear materials, The Institute of Physics and Power Engineering (IPPE) at Obninsk, Russia, has been computerizing its materials protection, control, and accountability capabilities. This is being accomplished in collaboration with the CoreMAS team at Los Alamos National Laboratory. Such international cooperation in applying advanced science and technology to managing and controlling nuclear materials will help reduce the threat of nuclear weapons proliferation by preventing acquisition of weapons-grade nuclear materials by unauthorized individuals, organizations, or states. One important characteristic of IPPE is that it encompasses several facilities that manage nuclear materials, and three of these facilities already operate their own independent (or independently developed) computerized accounting systems. This paper focuses on the importance of compatibility between the computerized accountability systems at the facilities, the ability of the individual systems to communicate with a single site-wide system, and the necessity of coordination between facilities in designing and developing computerized systems. The authors believe that the lessons learned at IPPE in coordinating these efforts have wide-ranging significance for other sites with multiple facilities

  12. Semi-annual report on strategic special nuclear material inventory differences

    This fourteenth periodic semiannual report of Inventory Differences (ID) covers the last six months of fiscal year 1983 (April 1, 1983 through September 30, 1983), for the Department of Energy (DOE) and DOE contractor facilities possessing significant quantities of strategic special nuclear material (SSNM). Inventory Differences are expected in nuclear material processing and are not, in and of themselves, evidence of lost or stolen material. On the other hand, ID analysis provides valuable information on the effectiveness of the safeguards system's physical protection and material control measures as well as a check on the process controls and material management procedures. ID's outside safeguards control limits or involving a missing SSNM discrete item are investigated. If necessary, an operation may be shut down until an ID is resolved

    2010-01-01

    Security of a nuclear material in an installation is determined by how far the installation is to assure that nuclear material remains at a predetermined location. This paper observed a preliminary design on nuclear material tracking system in the installation for decision making support based on multi sensor fusion that is reliable and accurate to ensure that the nuclear material remains inside the control area. Capability on decision making in the Management Information System is represented by an understanding of perception in the third level of abstraction. The second level will be achieved with the support of image analysis and organizing data. The first level of abstraction is constructed by merger between several CCD camera sensors distributed in a building in a data fusion representation. Data fusion is processed based on Wavelett approach. Simulation utilizing Matlab programming shows that Wavelett fuses multi information from sensors as well. Hope that when the nuclear material out of control regions which have been predetermined before, there will arise a warning alarm and a message in the Management Information System display. Thus the nuclear material movement time event can be obtained and tracked as well. (author)

    For the pyroprocessing facility to be commercialized in future, current regulations should be evaluated and developed in advance, based on the new types of nuclear materials in the facility. Physical protection system, especially, requires reasonable and reliable categorization of nuclear materials, to prevent from the theft of nuclear materials. In this paper, therefore, current categorization methods of nuclear material are investigated and applied to the pyroprocessing facility. After inconsistencies and gaps are found among methods, they are compared and discussed based on eight considering points (i.e, degrees of attractiveness, levels of category, discount factor, physical barriers, chemical barriers, isotopic barriers, radiological barriers, and capabilities of adversaries), to roughly suggest a new method for categorization. Current categorization methods of nuclear material, including IAEA's INFCIRC/225, U.S. DOE's method, newly expected U.S. NRC's method, FOM, and Bunn's approach, are different and can bring inconsistencies of physical protection requirements. The gap among methods will be significant if advanced fuel cycles are applied to them for the future. For example, the categorization results of 5 target materials in pyroprocessing facility show clear inconsistencies, while TRU ingot is considered the most attractive material. To resolve inconsistencies, it is necessary to determine new method suitable to pyroproessing facility, by considering the effects of eight points (i.e, degrees of attractiveness, levels of category, discount factor, physical barriers, chemical barriers, isotopic barriers, radiological barriers, and capabilities of adversaries)

    1979-01-01

    The statistical accountancy system developed at JRC Ispra is refered as 'NUMSAS', ie Nuclear Material Statistical Accountancy System. The principal feature of NUMSAS is that in addition to an ordinary material balance calcultation, NUMSAS can calculate an estimate of the standard deviation of the measurement error accumulated in the material balance calculation. The purpose of the report is to describe in detail, the statistical model on wich the standard deviation calculation is based; the computational formula which is used by NUMSAS in calculating the standard deviation and the information about nuclear material measurements and the plant measurement system which are required as data for NUMSAS. The material balance records require processing and interpretation before the material balance calculation is begun. The material balance calculation is the last of four phases of data processing undertaken by NUMSAS. Each of these phases is implemented by a different computer program. The activities which are carried out in each phase can be summarised as follows; the pre-processing phase; the selection and up-date phase; the transformation phase, and the computation phase

    Safety in any facility in the nuclear fuel cycle is a fundamental goal. However, it is recognized that, for example, should an accident occur in either the U.S. or Russia, the results could seriously delay joint activities to store and disposition weapons fissile materials in both countries. To address this, plans are underway jointly to develop a nuclear materials facility safety initiative. The focus of the initiative would be to share expertise which would lead in improvements in safety and safe practices in the nuclear fuel cycle.The program has two components. The first is a lab-to-lab initiative. The second involves university-to-university collaboration.The lab-to-lab and university-to-university programs will contribute to increased safety in facilities dealing with nuclear materials and related processes. These programs will support important bilateral initiatives, develop the next generation of scientists and engineers which will deal with these challenges, and foster the development of a safety culture

    1994-01-01

    The need for a useful nuclear materials database to assist in the management of nuclear materials within the Department of Energy (DOE) Weapons Complex is becoming significantly more important as the mission of the DOE Complex changes and both international safeguards and storage issues become drivers in determining how these materials are managed. A well designed nuclear material inventory database can provide the Nuclear Materials Manager with an essential cost effective tool for timely analysis and reporting of inventories. This paper discusses the use of databases as a management tool to meet increasing requirements for accurate and timely information on nuclear material inventories and related information. From the end user perspective, this paper discusses the rationale, philosophy, and technical requirements for an integrated database to meet the needs for a variety of users such as those working in the areas of Safeguards, Materials Control and Accountability (MC ampersand A), Nuclear Materials Management, Waste Management, materials processing, packaging and inspection, and interim/long term storage

    Full text: The paper gives a general overview of the progress which has been made in the activities on prevention and combating of illicit trafficking of nuclear material in Lithuania. It describes the measures which were taken to strengthen nuclear material accounting and control and physical protection. The current status of the national legislation and the functions of institutions involved in control of nuclear material and combating of illicit trafficking are discussed. Lithuania, similar to many countries, did not avoid a new type of a crime - smuggling of nuclear materials - which was observed in the 1990's. The most serious case in Lithuania happened in 1993 when fresh fuel assembly was stolen from Ignalina NPP. This assembly contains approximately 124 kg of UO 2 (enrichment 2%). 100 kg of the pellets from this assembly was found later in several pieces at different places. This case served as a strong stimulus to strengthen prevention measures of Illicit trafficking. The legal basis was created and governmental institutions were obliged with special duties related with nuclear material. The laws and regulations set the order for the shipment and handling of nuclear material. The penalties for violation of these laws and regulations specified in Penal Code and Administrative Code were made stricter. The State system of accounting for and control of nuclear material (SSAC) is a very important element in prevention of the illicit trafficking. The Regulations of Accounting for and Control of Nuclear Material at Nuclear Facilities and LOFs was issued by the State Nuclear Power Safety Inspectorate (VATESI) on 10 December 1997 following the provisions of the Law on Nuclear Energy. Lithuania extended its international obligations by ratifying the Protocol Additional to the Safeguards Agreement (entered into force on 5 July 2000). The fully computerized nuclear material accountancy system was created at Ignalina NPP. The system gives the possibility to find the

The Department for Nuclear Materials (DMN) has for its missions: - to contribute, through theoretical and experimental investigations, to the development of knowledge in materials science in order to be able to predict the evolution of the material physical and mechanical properties under service conditions (irradiation, thermomechanical solicitations, influence of the environment,..); - to characterize the properties of the materials used in the nuclear industry in order to determine their performance and to be able to predict their life expectancy, in particular via modelling. These materials can be irradiated or not, and originate from surveillance programs, experimental neutron irradiations or simulated irradiations with charged particles; - to establish, maintain and make use of the databases generated by these data; - to propose new or optimized materials, satisfying future service conditions and extend the life or the competitiveness of the associated systems; - to establish constitutive laws and models for the materials in service, incidental, accidental and storage conditions, and contribute to the development of the associated design codes in order to support the safety argumentation of utilities and vendors; - to provide expertise on industrial components, in particular to investigate strain or rupture mechanisms and to offer leads for improvement. This document presents, first, the purpose of the LECI (Historical data, Strategy, I and K shielded cell lines (building 605), M shielded cell line (building 625), Authorized materials).

    The LOF is the abbreviation of Location outside Facilities using in safeguards. IAEA want to control the location using the small nuclear material over the world. The depleted uranium used in Industrial field should be controlled by the Government according to the agreement between the IAEA and the ROK. From 2006, The ROK is managing the locations in the LOF. The detail article governing the locations is on the Location attachment agreed between two bodies. As of end of 2007, The LOF was consisting of 64 locations. Now, A number of Locations are increasing up to 75. The KINAC(Korea Institute of Nuclear Nonproliferation and Control) is controlling the data about the amount of nuclear material in LOF. The KINAC is trying to upgrade the efficiency and accuracy about the data. The KINAC will make a storage house at the underground of head office from 2009. The purpose of the storage system in KINAC is gathering the nuclear material, which is difficult to control by the industries, especially the nuclear material involved in LOF. The final goal for gathering the nuclear materials are recycling to new another machine. I would like to introduce the handling case of the Depleted uranium in their countries. On this paper, I will show 4 countries case briefly

    Robots have successfully invaded industry where they have replaced costly personnel performing their tasks cheaper and better in most cases. There may be a place for a unique class of robots, security robots, in nuclear materials management. Robots could be employed in the functions of general response, patrol and neutralizing dangerous situations. The last is perhaps most important. Ion Track Instruments of Burlington, Massachusetts has designed an excellent unit to protect life in hazardous situations. The unit can detect, disrupt or remove explosives. It can enter dangerous areas to reconnoiter the extent of danger. It can communicate with those in a dangerous area. It can fight fires or clean an area using a 2 1/2 inch, two man hose. If necessary, it can engage an adversary in a fire fight using a twelve gauge shot gun

    Full text: This paper presents an overview of the national approaches to physical protection of nuclear materials in Central Eastern Europe (CEE), with an emphasis on Poland. Soviet influence in the past led to inadequate safety culture in nuclear activities and insufficient security of nuclear materials and facilities in the region. In the centralized economies all aspects of nuclear activities, including ownership of the nuclear facilities, were the responsibility of the state with no clear separation between regulating and promoting functions. During the last decade a significant progress has been made in the region to clean up the legacy of the past and to improve practices in physical protection of nuclear materials. The countries of Central Eastern Europe have had many similar deficiencies in nuclear field and problems to overcome, but cannot be viewed as a uniform block. There are local variations within the region in a size of nuclear activities, formulated respective regulations and adopted measures to secure nuclear materials and facilities. Nevertheless, all twelve nations, with nuclear reactors and without nuclear facilities, have joined the convention on the physical protection of nuclear material and most of them declare that they have followed the IAEA recommendations INFCIRC/225/Rev.4 to elaborate and implement their physical protection systems of nuclear materials and facilities. The largest request for an international advisory mission (IPPAS) to review states' physical protection systems and to address needs for improvement was received from the countries of Central Eastern Europe. Poland belongs to the beneficiaries where the IPPAS mission and later follow-up consultations resulted in physical protection upgrade of the research reactor under the IAEA/US/UK technical assistance project. A powerful incentive to the progress made in a number of CEE countries was the goal of accession to the European Union. The physical protection of nuclear

    The MC and A Equipment and Methodological Support Strategic Plan (MEMS SP) for implementing modern MC and A equipment and methodologies at Rosatom facilities has been developed within the framework of the U.S.-Russian MPC and A Program. This plan developed by the Rosatom's Russian MC and A Equipment and Methodologies (MEM) Working Group and is coordinated by that group with support and coordination provided by the MC and A Measurements Project, Office of National Infrastructure and Sustainability, US DOE. Implementation of different tasks of the MEMS Strategic Plan is coordinated by Rosatom and US-DOE in cooperation with different U.S.-Russian MC and A-related working groups and joint site project teams. This cooperation allows to obtain and analyze information about problems, current needs and successes at Rosatom facilities and facilitates solution of the problems, satisfying the facilities' needs and effective exchange of expertise and lessons learned. The objective of the MEMS Strategic Plan is to enhance effectiveness of activities implementing modern equipment and methodologies in the Russian State MC and A system. These activities are conducted within the joint Russian-US MPC and A program aiming at reduction of possibility for theft or diversion of nuclear materials and enhancement of control of nuclear materials

    The Fieldable Nuclear Material Identification System (FNMIS), funded by the NA-241 Office of Dismantlement and Transparency, provides information to determine the material attributes and identity of heavily shielded nuclear objects. This information will provide future treaty participants with verifiable information required by the treaty regime. The neutron interrogation technology uses a combination of information from induced fission neutron radiation and transmitted neutron imaging information to provide high confidence that the shielded item is consistent with the host's declaration. The combination of material identification information and the shape and configuration of the item are very difficult to spoof. When used at various points in the warhead dismantlement sequence, the information complimented by tags and seals can be used to track subassembly and piece part information as the disassembly occurs. The neutron transmission imaging has been developed during the last seven years and the signature analysis over the last several decades. The FNMIS is the culmination of the effort to put the technology in a usable configuration for potential treaty verification purposes.

    1992-01-01

    This volume brings together 47 papers from scientists involved in the fabrication of new nuclear fuels, in basic research of nuclear materials, their application and technology as well as in computer codes and modelling of fuel behaviour. The main emphasis is on progress in the development of non -oxide fuels besides reporting advances in the more conventional oxide fuels. The two currently performed large reactor safety programmes CORA and PHEBUS-FP are described in invited lectures. The contributions review basic property measurements, as well as the present state of fuel performance modelling. The performance of today's nuclear fuel, hence UO 2 , at high burnup is also reviewed with particular emphasis on the recently observed phenomenon of grain subdivision in the cold part of the oxide fuel at high burnup, the so-called 'rim' effect. Similar phenomena can be simulated by ion implantation in order to better elucidate the underlying mechanism and reviews on high resolution electron microscopy provide further information. The papers will provide a useful treatise of views, ideas and new results for all those scientists and engineers involved in the specific questions of current nuclear waste management

    International Nuclear Information System (INIS)

    1963-01-01

    The last two decades have witnessed an enormous development in chemical analysis. The rapid progress of nuclear energy, of solid-state physics and of other fields of modern industry has extended the concept of purity to limits previously unthought of, and to reach the new dimensions of these extreme demands, entirely new techniques have been invented and applied and old ones have been refined. Recognizing these facts, the International Atomic Energy Agency convened a Panel on Analytical Chemistry of Nuclear Materials to discuss the general problems facing the analytical chemist engaged in nuclear energy development, particularly in newly developing centre and countries, to analyse the represent situation and to advise as to the directions in which research and development appear to be most necessary. The Panel also discussed the analytical programme of the Agency's laboratory at Seibersdorf, where the Agency has already started a programme of international comparison of analytical methods which may lead to the establishment of international standards for many materials of interest.

    International Atomic Energy Agency (IAEA) has requested Korea to establish and manage the law ruling all nuclear materials through the INFCIRC/153. Now, it has been 30 years since Korea made the agreement, INFCIRC/153, with IAEA. Korea has tried their best to accomplish the international standard in nuclear control field and it is a fact that Korea finally produced some results in the nuclear control field. Related to nuclear material control, Korea is above the common level appropriately ranked 6th in the world in terms of nuclear power. Before 2000, Korea was making the foundation secure in the nuclear control. IAEA did not urge to establish the law supervising the small-quantity nuclear material and depleted uranium (DU). In a turnaround from early IAEA moderate line to Korea, the situation was changed. Since IAEA brought up the agenda to 2000 Joint Review Meeting between Korea-IAEA, IAEA has asked Korea to establish the control system for smallquantity nuclear material and DU. In 2003, the Korean government set up a project establishing the control system about all nuclear material including small-quantity nuclear material and DU. National Nuclear Management and Control Agency (NNCA), delegating the business relating to international controlling materials from government, developed some modules in nuclear material control system and operated it. The system includes a controlling system for small-quantity nuclear material. NNCA on behalf of government has collected the information and Korea Ministry of Science and Technology (MOST) has reported the information to the IAEA. This paper introduces you the background of controlling the small-quantity nuclear material and the system of controlling nuclear material in Korea. And it will suggest the improvement of the management method in the system for small-quantity nuclear material.

    As it is known, for the fact that the illicit trafficking and trading of nuclear materials are being increased over the past few years because of the huge demand of third world states. Nuclear materials like uranium, plutonium, and thorium are used in nuclear explosives that have very attractive features for crime groups, terrorist groups and, the states that are willing to have this power. Crime groups that make illegal trade of nuclear material are also trying to market strategic radioactive sources like red mercury and Osmium. This kind of illegal trade threats public safety, human health, environment also it brings significant threat on world peace and world public health. For these reasons, both states and international organizations should take a role in dealing with illicit trafficking. An important precondition for preventing this kind of incidents is the existence of a strengthened national system for control of all nuclear materials and other radioactive sources. Further, Governments are responsible for law enforcement within their borders for prevention of illegal trading and trafficking of nuclear materials and radiation sources

    To address the current and future needs for nuclear materials management and safeguards information, Lawrence Livermore National Laboratory envisions an integrated nuclear information system that will support several functions. The vision is to link distributed information systems via a common communications infrastructure designed to address the information interdependencies between two major elements: Domestic, with information about specific nuclear materials and their properties, and International, with information pertaining to foreign nuclear materials, facility design and operations. The communication infrastructure will enable data consistency, validation and reconciliation, as well as provide a common access point and user interface for a broad range of nuclear materials information. Information may be transmitted to, from, and within the system by a variety of linkage mechanisms, including the Internet. Strict access control will be employed as well as data encryption and user authentication to provide the necessary information assurance. The system can provide a mechanism not only for data storage and retrieval, but will eventually provide the analytical tools necessary to support the U.S. government's nuclear materials management needs and non-proliferation policy goals

    1966-02-15

    An increasing number of countries are using nuclear materials which, because of their high value and the potential hazards involved, require special methods of handling. To discuss these and to provide a forum at which different systems for achieving the necessary economy and safety could be compared, the International Atomic Energy Agency held a Symposium at Vienna on Nuclear Materials Management from 30 August to 3 September, 1965. It was attended by 115 participants from 19 Member States and two international organizations. Nuclear materials are already being used on an industrial scale and their high cost demands close and continuous control to ensure that they are delivered precisely on time and that they are used to the fullest possible extent before they are withdrawn from service. Routine industrial methods of material control and verification are widely used to ensure safe and economical operation and handling in nuclear power stations, in fuel-element fabrication and reprocessing plants, and in storage facilities. In addition special refinements are needed to take account of the value and the degree of purity required of nuclear materials. Quality as well as quantity has to be checked thoroughly and the utmost economy in processing is necessary. The radioactivity of the material poses special problems of handling and storage and creates a potential hazard to health. A further problem is that of criticality. These dangers and the means of averting them are well understood, as is evidenced by the outstandingly good safety record of the atomic energy industry. But besides accommodating all these special problems, day-to-day procedures must be simple enough to fit in with industrial conditions. Many of the 58 papers presented at the Symposium emphasized that records, checks, measurements and handling precautions, if suitably devised, provide the control vital to efficient operation, serve as checks against loss or waste of valuable materials and help meet the

    1999-01-01

    The Advanced Research Workshop (ARW) on Nuclear Materials Safety held June 8-10, 1998, in St. Petersburg, Russia, was attended by 27 Russian experts from 14 different Russian organizations, seven European experts from six different organizations, and 14 U.S. experts from seven different organizations. The ARW was conducted at the State Education Center (SEC), a former Minatom nuclear training center in St. Petersburg. Thirty-three technical presentations were made using simultaneous translations. These presentations are reprinted in this volume as a formal ARW Proceedings in the NATO Science Series. The representative technical papers contained here cover nuclear material safety topics on the storage and disposition of excess plutonium and high enriched uranium (HEU) fissile materials, including vitrification, mixed oxide (MOX) fuel fabrication, plutonium ceramics, reprocessing, geologic disposal, transportation, and Russian regulatory processes. This ARW completed discussions by experts of the nuclear materials safety topics that were not covered in the previous, companion ARW on Nuclear Materials Safety held in Amarillo, Texas, in March 1997. These two workshops, when viewed together as a set, have addressed most nuclear material aspects of the storage and disposition operations required for excess HEU and plutonium. As a result, specific experts in nuclear materials safety have been identified, know each other from their participation in t he two ARW interactions, and have developed a partial consensus and dialogue on the most urgent nuclear materials safety topics to be addressed in a formal bilateral program on t he subject. A strong basis now exists for maintaining and developing a continuing dialogue between Russian, European, and U.S. experts in nuclear materials safety that will improve the safety of future nuclear materials operations in all the countries involved because of t he positive synergistic effects of focusing these diverse backgrounds of

  5. Evaluating the attractiveness of nuclear material for proliferation-resistance and nuclear security

    International Nuclear Information System (INIS)

    The attractiveness of nuclear material, defined as a function of the isotopic composition of the nuclear material in formulas expressing the material's intrinsic properties, is of considerably debate in recent developments of proliferation-resistance measures of a nuclear energy system. A reason for such debate arises from the fact that the concept of nuclear material attractiveness can be confusing because the desirability of a material for nuclear explosive use depends on many tangible and intangible factors including the intent and capability of the adversary. In addition, a material that is unattractive to an advanced nation (in the case of proliferation) may be very attractive to a terrorist (in the case of physical protection and nuclear security). Hence, the concept of 'Nuclear Material Attractiveness' for different nuclear materials must be considered in the context of safeguards and security. The development of a ranking scheme on the attractiveness of nuclear materials could be a useful concept to start-off the strategies for safeguards and security on a new footing (i.e., why and how nuclear material is attractive, and what are the quantifiable basis). Japan may benefit from such concept regarding the attractiveness of nuclear materials when recovering nuclear materials from the damaged cores in Fukushima because safety, security, and safeguards (3S) would be a prominent consideration for the recovery operation, and it would be the first time such operation is performed in a non-nuclear weapons state.

    Using Segmented Gamma Scanning(SGS) System and coaxical Ge detector, the amounts of uranium in 55 gallon waste drums mixed with low density matrix material were determined by segmented gamma-scanning method. Various factors that influence sample measurement were identified as attenuation effects against sample container and matrix material counting loss effect by dead time and signal pile-up and radial and axial non-uniformity effects of sample. External transmission source, Yb-169, was used to correct gamma-ray attenuation by matrix material. The measure deviation caused by non-uniform distribution in the drum was minimized by rotating and dividing the drum. To calibrate the measurement system, calibration sources were prepared in the range of 50g, 100g, 300g, and 500g of U0 2 powder which let it stick to thin gummed papers and mix with other matrix materials such as papers, vinyl sheets, pieces of rubber gloves in 4 each drum. Under the calibrated assay system the uncertainty of measured amounts of UO 2 powder approached about 10% of absolute value at 1σ and a normal flow of waste stream can be maintained at least one drum per hour. On the other hand, in an effort to ease the nuclear material accounting for and control the flow of nuclear material in CANDU Fuel Fabrication Facility was analyzed to develope a model computer network interfaced with hardwares, structual design of network, computer operating system, and hardware set-up were studied to draw out the most practical network system.

    Full text: The Republic of Belarus strives to take an active part in international cooperation in the field of prevention and interception of illicit uses of nuclear material and radioactive sources through: multilateral international agreements and bilateral interagency treatments; information exchange within the IAEA Illicit Trafficking Database; participation in different international seminars, workshops, conferences including those under the IAEA auspices etc. Belarus is constantly improving regulatory, legal and technical aspects of activities aimed at: accounting, control and ensuring of physical protection of nuclear material and security of radioactive sources; exercising efficient control over their export and import; detecting cases of their illicit uses and illegal cross-border movements and informing of such cases through the IAEA Illicit Trafficking Database; developing and providing training opportunities for personnel. Through Resolution 'On Measures for Physical Protection of Nuclear Materials' issued by the Council of Ministers in 1993, Committee for Supervision of Industrial and Nuclear Safety (PROMATOMNADZOR) was appointed as the authority responsible for ensuring physical protection of nuclear materials and facilities. Through Resolution 'On Measures for Fulfillment of Provisions of the Non-Proliferation Treaty' issued by the Council of Ministers in 1993, Promatomnadzor was designated as the national competent authority responsible for the establishment and maintenance of the State System of Accounting and Control of nuclear material. The system accounts all the nuclear material meeting the criteria defined in the Safeguards Agreement with the IAEA. The system includes two levels: i.e. on-site accounting and control and state accounting and control exercised by Promatomnadzor. Apart from reporting to the Agency, the system also provides for national tasks being accomplished: control over uses of nuclear material, its physical protection, access

    the environment. Ghana seeks to build upon the established regulatory control programme for the control of ionizing radiation and radiation sources and to expand it to cover combating of illicit trafficking of nuclear materials of socio-economic importance. The prevention of strategy will involve developing a national system for the accountability, control and security of nuclear materials. Technical measures to detect Illicit trafficking of nuclear materials and other radioactive materials and response to illicit trafficking will be developed. The programme will include screening of vehicles and individuals at borders to: (i) detect smuggling of these materials; (ii) locate, measure and characterize the source of radiation; and (iii) fully characterize any confiscated materials. An effective countermeasure will be established through a system of (i) Prevention: Establishment of national system of accounting and control of nuclear materials; Legislation and regulations; Physical Protection; Export/Import control; (ii) Response to illicit trafficking through: Establishing anti-trafficking infrastructure, which includes responsible authorities such as customs, civil aviation authority, police, nuclear regulatory authority, military intelligence and defense agencies, and district assemblies coordinating and collaborating in combating illicit trafficking: (iii) Provision of detecting equipment for nuclear materials and (iv) Training which will cater to: response personnel and the public. Training opportunities provided by the IAEA will be fully utilized. International collaboration with our near neighbors, Togo, Cote d'lvoire and Burkina Faso, will be established to ensure cross border control. (author)

    The German system to prevent, detect and respond to illicit uses of nuclear materials and radioactive sources consists of a variety of different elements: International and national laws and regulations covering safeguards, physical protection, and import/export control; Licensing and regulatory supervision of all activities related to nuclear materials and radioactive sources, including import and export; Responsibility of the licensee to ensure compliance with licensing conditions; sanctions; Law enforcement by police, security and customs authorities; prosecution and penalties; Detection of illicitly trafficked radioactive materials through intelligence and technical means; analysis capabilities; Response arrangements for normal and for severe cases of illicit use of nuclear materials; Participation in international programmes and POC-systems. Safeguards measures have been implemented in Germany in accordance with the Non- Proliferation Treaty and with safeguards agreements based on INFCIRC/153. As Germany is a member of the European Union, the Euratom Treaty and the Euratom-Ordinance Nr. 3227/76 together with the Verification Agreement between the IAEA, the European Commission and the European Member States have led to safeguards measures jointly implemented by the IAEA and by Euratom. The relevant international law for the physical protection of nuclear material in force in Germany is the Convention on the Physical Protection of Nuclear Material. The recommendations on physical protection objectives and fundamentals and on physical protection measures specified in INFCIRC/225/Rev. 4 have been taken into account in various national regulations pertaining to the national design basis threat, the physical protection of LWR nuclear power plants, of interim spent fuel storage facilities, of facilities containing category III material, of nuclear material and radioactive waste transports by road or railway vehicles, aircraft or sea vessels; additional guidelines

    The reprocessing of irradiated HEU MTR fuel is a sensible part of a safeguards regime. It brings together fuel otherwise scattered around the world into a concerted accountancy and protection arrangement. From a nuclear material accountants view the overall accountancy performance has been excellent.

    The reprocessing of irradiated HEU MTR fuel is a sensible part of a safeguards regime. It brings together fuel otherwise scattered around the world into a concerted accountancy and protection arrangement. From a nuclear material accountants view the overall accountancy performance has been excellent. While investigations have been required for a few individual MUFs or trends, very little effort has required to be expended by the Nuclear Materials Control Department. That is a definition of a 'good plant'; it operates, measures and records input and output streams, and then the accountancy falls into place.

    Machine protection, as part of accelerator control systems, can be managed with a 'functional safety' approach, which takes into account product life cycle, processes, quality, industrial standards and cybersafety. This paper will discuss strategies to manage such complexity and the related risks, with particular attention to fail-safe design and safety integrity levels, software and hardware standards, testing, and verification philosophy. It will also discuss an implementation of a machine protection system at the SLAC National Accelerator Laboratory's Linac Coherent Light Source (LCLS).

    An automated system was developed of nuclear materials accounting in Czechoslovakia. The system allows automating data processing including data storage. It comprises keeping records of inventories and material balance. In designing the system, the aim of the IAEA was taken into consideration, ie., building a unified information system interconnected with state-run systems of accounting and checking nuclear materials in the signatory countries of the non-proliferation treaty. The nuclear materials accounting programs were written in PL-1 and were tested at an EC 1040 computer at UJV Rez where also the routine data processing takes place. (B.S.)

    The US has agreed to pursue cooperative nuclear Material Protection, Control and Accounting (MPC and A) programs with the Republic of Kazakstan. As part of this cooperation, a state system of control accounting and physical protection for nuclear materials is being developed. The US Department of Energy is providing assistance at the four nuclear sites in the Republic to enhance MPC and A systems, techniques, hardware, software, procedures, and training. US survey teams, which include both material control and accounting (MC and A) and physical protection experts, have visited four nuclear sites in Kazakstan. MPC and A assistance is being provided to the Ulba State Holding Company, the Institute of Atomic Energy at Kurchatov City and Ala Tau, and the Mangyshlak Atomic Energy Complex (MAEC) BN-350 nuclear power plant in Aktau. At these sites, the facility staffs and DOE technical teams are working together to identify conditions not completely conforming with accepted international standards, as well as potential enhancements to correct such conditions. Design packages for enhancements at each of these facilities are prepared in collaboration with Kazakstani specialists. After agreement is reached on the specifications by the US and Kazakstan, MPC and A equipment is procured and installed. This paper summarizes the approach to the cooperative programs at these facilities, program status, and future plans

    Full text: Nuclear material is vulnerable to a range of theft, sabotage, smuggling and illicit use scenarios. These scenarios are dependent on the choices of individuals and organizations involved in these activities. These choices, in turn; are dependent on the perceived payoff vectors of the involved players. These payoff vectors can include monetary gain, ability to avoid detection, penalties for detection, difficulty of accomplishment, resource constraints, infrastructure support, etc. Threat scenarios can be developed from these individual choices, and the set of worst-case threat scenarios can be compiled into a threat definition. The implementation of physical protection controls is dependent on the developed threat scenarios. The analysis of the composition of the postulated threat can be based on the analysis of the postulated decisions of the individuals and organizations involved on theft, smuggling, and illicit use. This paper proposes a model to systematically analyze the significant decision points that an individual or organization addresses as result of its goals. The model's dependence on assumptions is discussed. Using these assumptions, a model is developed that assigns probabilities to a set of decisions performed by the individuals involved in theft/smuggling. The individual and organisation's decisions are based on the perceived cost/benefit of the decisions and the resource constraints. Methods for functionally obtaining decision probabilities from perceived cost/benefit are proposed. The treatment of high-consequence/low-probability events is discussed in terms of analysis of precursor events, and the use of sensitivity analysis is discussed. An example of a simplified model for nuclear material theft, smuggling, and illicit use is presented, and the results of this simplified model are evaluated. By attempting to model the potential distribution of nuclear material theft/smuggling events, this model increases the analytical tools available

    1996-01-01

    Robotic systems are being developed by the Intelligent Systems and Robotics Center at Sandia National Laboratories to perform automated handling tasks with radioactive nuclear materials. These systems will reduce the occupational radiation exposure to workers by automating operations which are currently performed manually. Because the robotic systems will handle material that is both hazardous and valuable, the safety of the operations is of utmost importance; assurance must be given that personnel will not be harmed and that the materials and environment will be protected. These safety requirements are met by designing safety features into the system using a layered approach. Several levels of mechanical, electrical and software safety prevent unsafe conditions from generating a hazard, and bring the system to a safe state should an unexpected situation arise. The system safety features include the use of industrial robot standards, commercial robot systems, commercial and custom tooling, mechanical safety interlocks, advanced sensor systems, control and configuration checks, and redundant control schemes. The effectiveness of the safety features in satisfying the safety requirements is verified using a Failure Modes and Effects Analysis. This technique can point out areas of weakness in the safety design as well as areas where unnecessary redundancy may reduce the system reliability

    Research reactors are required (in accordance with the Safeguards Agreement between the State and the IAEA) to maintain a system of nuclear material accounting and control for reporting quantities of nuclear material received, shipped, and held on inventory. Enhancements to the existing accounting and control system can be made at little additional cost to the facility, and these enhancements can make nuclear material accounting and control useful for nuclear security. In particular, nuclear material accounting and control measures can be useful in protecting against an insider who is intent on unauthorized removal or misuse of nuclear material or misuse of equipment. An enhanced nuclear material accounting and control system that responds to nuclear security is described in NSS-25G, Use of Nuclear Material Accounting and Control for Nuclear Security Purposes at Facilities, which is scheduled for distribution by the IAEA Department of Nuclear Security later this year. Accounting and control measures that respond to the insider threat are also described in NSS-33, Establishing a System for Control of Nuclear Material for Nuclear Security Purposes at a Facility During Storage, Use and Movement, and in NSS-41, Preventive and Protective Measures against Insider Threats (originally issued as NSS-08), which are available in draft form. This paper describes enhancements to existing material control and accounting systems that are specific to research reactors, and shows how they are important to nuclear security and protecting against an insider.

  20. Uncertainty estimation in nuclear material weighing

    2011-12-15

    The assessment of nuclear material quantities located in nuclear plants requires knowledge of additions and subtractions of amounts of different types of materials. Most generally, the quantity of nuclear material held is deduced from 3 parameters: a mass (or a volume of product); a concentration of nuclear material in the product considered; and an isotopic composition. Global uncertainties associated with nuclear material quantities depend upon the confidence level of results obtained in the measurement of every different parameter. Uncertainties are generally estimated by considering five influencing parameters (ISHIKAWA's rule): the material itself; the measurement system; the applied method; the environmental conditions; and the operator. A good practice guide, to be used to deal with weighing errors and problems encountered, is presented in the paper.

    Tracking nuclear materials production and processing, particularly covert operations, is a key national security concern, given that nuclear materials processing can be a signature of nuclear weapons activities by US adversaries. Covert trafficking can also result in homeland security threats, most notably allowing terrorists to assemble devices such as dirty bombs. Existing methods depend on isotope analysis and do not necessarily detect chronic low-level exposure. In this project, indigenous organisms such as plants, small mammals, and bacteria are utilized as living sensors for the presence of chemicals used in nuclear materials processing. Such 'metabolic fingerprinting' (or 'metabonomics') employs nuclear magnetic resonance (NMR) spectroscopy to assess alterations in organismal metabolism provoked by the environmental presence of nuclear materials processing, for example the tributyl phosphate employed in the processing of spent reactor fuel rods to extract and purify uranium and plutonium for weaponization.

    The nonproliferation community is currently addressing concerns that the access to special nuclear materials may increase the illicit trafficking in weapons-usable materials from civil and/or weapons material stores and/or fuel cycles systems. Illicit nuclear traffic usually involves reduced quantities of nuclear materials perhaps as samplings of a potential protracted diversionary flow from sources to users. To counter illicit nuclear transactions requires the development of techniques and methods in nuclear material traceability as an important phase of a broad forensic analysis capability. This report discusses how isotopic signatures and correlation methods were applied to determine the origins of Highly Enriched Uranium (HEU) and Plutonium samples reported as illicit trafficking in nuclear materials

    Control and safety systems as well as operation procedures are designed on the basis of critical process parameters limits. The expectation is that short and long term mechanical damage and process failures will be avoided by operating the plant within the specified constraints envelopes. In this paper, one of the Advanced Liquid Metal Reactor (ALMR) design duty cycles events is discussed to corroborate that the time has come to explicitly make component protection part of the control system. Component stress assessment and aging data should be an integral part of the control system. Then transient trajectory planning and operating limits could be aimed at minimizing component specific and overall plant component damage cost functions. The impact of transients on critical components could then be managed according to plant lifetime design goals. The need for developing methodologies for online transient trajectory planning and assessment of operating limits in order to facilitate the explicit incorporation of damage assessment capabilities to the plant control and protection systems is discussed. 12 refs

    The United States is one of several donor states providing technical assistance to the Newly Independent States (NIS) of the Former Soviet Union (FSU) for improving their systems for control of nuclear materials. Ukraine and Kazakstan have significant nuclear energy programs. Both countries have committed to nonproliferation of nuclear weapons. They have signed the NPT and have safeguards agreements with the U.S. concerning development of state systems of control, accounting and physical protection of nuclear materials. As directed by the DOE - International Safeguards Division (now the DOE - Russia/NIS Nuclear Materials Security Task Force), technical specialists from several national laboratories, including Argonne, Los Alamos, Oak Ridge, Pacific Northwest and Sandia, as well as representatives of other U.S. Government organizations, such as the NRC, DOD/DNA and the New Brunswick Laboratory, are interacting with government regulatory and facility personnel of Ukraine and Kazakstan. Argonne has program coordination responsibilities for both countries. In support of agreements between the U.S. and Ukraine and the U.S. and Kazakstan, the DOE is responsible for providing technical assistance and training to aid in the evaluation, design, development, and implementation of nuclear material safeguards. This assistance includes: (1) information systems for tracking and reporting the location of nuclear materials, (2) application of nuclear measurement techniques for verifying inventories, (3) material control and accounting (MC ampersand A) systems, and (4) physical protection (PP) systems. Site survey teams, including both MC ampersand A and PP experts from several national labs, have visited Ukraine and Kazakstan. This paper summarizes activities to date and future plans

    An urgent need calls out for improved border security and export control systems in the Central Asian and Caucasus regions to prevent illicit nuclear and radioactive materials trafficking. Effective nuclear and radiological exports controls are essential because these regions contain numerous nuclear facilities and radioactive materials as well as lie at the crossroads between seekers and suppliers of technologies that could be employed in nuclear and radiological weapons. Porous and unprotected borders compound these concerns. Moreover, the states within these regions are struggling with forming new regulations and laws, obtaining sufficient portal monitoring equipment, training customs and border security personnel, and coordinating these activities with neighboring states. Building this infrastructure all at once can severely task any government. Thus, unsurprisingly, most of these states have inadequate export control and border security systems. To enable each state in these regions determine how to better prevent illicit nuclear and radiological materials trafficking, the authors have developed a prototype system dynamics model focused on evaluating and improving of effectiveness of export controls. System dynamics modeling, a management tool that grew out of the field of system engineering and nonlinear dynamics, uses two structures: causal loop diagrams and stock and flow diagrams. The former shows how endogenous systematic factors interact with each other to produce feedback mechanisms that results in either balancing or reinforcing loops. A classic example is a arms race, modeled as a vicious cycle or reinforcing loop. In addition to interacting with each other, causal loops influence the flow of stock, which is material concern. In the export control system dynamics model, the stock represents nuclear and radioactive materials. System dynamics modelling is an iterative process that is continually modified by user input. Therefore, export control

    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.

    Nuclear material measurement is an important measure to determine the amount of nuclear material of each stage such as receipt, shipment, inventory and hold-up. The material accountancy based on the material balance among the measurements is a measure to control of nuclear material. The material accountancy, from the technical aspect, can be used as promising measures for purposes from operator's level to state's level such as the nuclear safety, property control and environmental preservation other than safeguards measures only to conclude no diversion of nuclear material. This paper discusses various purposes of nuclear material measurements and clarifies the certain function such as quality assurance to be expected at each purpose. Based on the discussion, critical points for the quality assurance of each stage are studied. (author)

    PNC is developing a wide area of nuclear fuel cycle. Therefore, much nuclear material with a various form exists at each facility in the Works, and the controls of the inventory changes and the physical inventories of nuclear material are important. Nuclear material accountancy is a basic measure in safeguards system based on Non-Proliferation Treaty(NPT). In the light of such importance of material accountancy, the data base of nuclear material control and the material accountancy report system for all facilities has been developed by using the computer. By this system, accountancy report to STA is being presented certainly and timely. Property management and rapid corresponding to inquiries from STA can be carried out by the data base system which has free item searching procedure. The present paper introduces 'Development of Data Base System for Nuclear Material Accountancy Data at PNC'. (author)

    The inadvertent and illegal movements of radioactive and nuclear materials are issues of increased national and international awareness. States are progressively becoming more conscious of the need to adequately respond to these events. As regards the States' regulatory infrastructure, the design and enforcement of control and verification measures to maintain the continuity of knowledge about possession, use and movements of radioactive and nuclear materials is of critical importance. The existence of an appropriate legislative framework and a regulatory authority empowered to establish effective safety and security measures are essential to prevent inadvertent and illegal movements of nuclear materials and other radioactive materials. The events of Sep. 11, 2001 in the US have increased the States' awareness on the need to review their national infrastructure to identify additional measures against inadvertent and illegal movements of radioactive and nuclear materials as well as against sabotage of nuclear facilities. Argentina has more than a half- century- old tradition regarding the control and supervision of all activities involving the use of nuclear and radioactive materials. The Nuclear Regulatory Authority (ARN) of Argentina is the organization with federal competence in radiation protection, nuclear safety, safeguards and physical protection. It is responsible for issuing licenses and permits to any activity involving radioactive materials and for controlling and verifying that these activities are performed in full compliance with ARN standards and requirements. In the region, Argentina has been playing an important role in the prevention of illicit traffic of nuclear and radioactive materials for the last years within the framework of Security Commission of MERCOSUR. The last goals of this initiative are to define and coordinate actions and to establish a set of common operational procedures in the countries participating in the mentioned multilateral

    One of tile most significant problems that will face investors, managers and operators in nuclear activities and especially in the field of commercial nuclear power, will be the proper control of a nuclear materials inventory that will exceed US $5000 million in value by 1980. Special nuclear materials are expensive when compared to most materials of commerce, e.g. US prices for 90% enriched uranium and 3% enriched uranium as hexafluoride, and for heavy water are $10 808, $254 and $61.60 per kg, respectively. Moreover, in many cases these materials are subjected because of health and safety requirements to special governmental controls not directly related to their monetary value. Despite the high monetary values assigned to these materials, they are destined to be used in large quantity, e.g. some 50- 75 t of 3% enriched material will be used in 500-MW light-water-moderated reactor, and perhaps the equivalent of 200 to 300 reactors of such size will be in operation throughout the world by 1980. Past experience has resulted in the development of special procedures and practice for the commercial control of the large quantity, lower-value materials such as coal or iron ore and for the small quantity, higher value materials such as the precious metals. While they have like prices, special nuclear materials are different in kind and will be handled in quantities much greater than the precious metals. However, while special techniques or special adaptations of old techniques may be necessary, proper use of various established inventory control practices should be sufficient in most cases to protect adequately the investment of nations and individuals in these expensive materials. This paper establishes criteria for materials control. It specifically considers the appropriateness of various techniques of inventory control ranging from annual balancing of book records of receipts and shipments through detailed daily physical inventory in the light of the specific value

    A material irradiation apparatus CIMAT (Capsula de Irradiacao de Materiais) with controlled temperature and atmosphere is described. The device was specifically designed to perform experiments inside the core of the IEA-R1 swimming pool reactor and allows fast neutron (E=1 MeV) irradiations of multiple miniature metallic samples at temperature between 100 deg C and 500 deg C, in Argon or Helium atmosphere to inhibit corrosion. The aim of CIMAT is to make a comparative assessment of Radiation Embrittlement (RE) on the AS 508 cl.3 steel, of different origins (ELETROMETAL-Brazil and VITCOVICE-Chekia) used in Pressure Vessels (PV) of PWR, for fluence of 10 exp 19 nvt at 300 C, by means of mechanical post irradiation evaluation. Previous characterization of non-irradiated samples of these materials is presented. In situ electrical and magnetic measurements, at high temperatures, are foreseen to be made with this apparatus. Extensive temperature stability and leak-tightness tests performed in the reactor swimming pool have proven the CIMAT to be intrinsically safe and operational. (author)

  1. Protecting the source. Securing nuclear material and strong radiation sources. New threats of terrorism are prompting the need for swift action to better secure nuclear material and strong radiation sources. Are measures already in place enough? The Stanford-Salzburg initiative suggests not

    At a time of growing concern over threats of terrorism, the security of nuclear and radioactive material is an urgent and serious issue. Working with a range of partners, the IAEA has put into place a multi-faceted Action Plan to help countries upgrade their capabilities. But more needs to be done to counter new types of threats. One particular area that needs to be strengthened is the physical protection of nuclear and radioactive material. The attacks of 11 September 2001 opened our eyes to i he urgent need to strengthen national physical protection (PP) practices for nuclear and other radioactive material. The principle that highly radioactive material will protect itself does not apply to the newest generation of terrorists. Existing PP systems were not designed to deal with the threat of suicidal terrorists commanding the numbers, skills, training, and resources available to those who carried out the attacks in the US. Moreover, because there are no mandatory international standards for domestic PP systems for nuclear or radioactive material, protection measures vary greatly from country to country. The IAEA recommended standards (Inference/225/Rev. 4) were not designed with the new terrorist threats in mind and national practices often fall short of even these recommendations. The result is inadequate protection against the new form of terrorism. Few argue the point that national physical protection practices for nuclear and other radioactive material need to be strengthened. This article summarizes a Stanford-Salzburg plan developed by experts from Stanford University's Center for International Security and Cooperation, (USA) and revised at the EU-Physical Protection NUMAT Conference in September 2002 in Salzburg, Austria. It includes six recommended elements to consider in addition to what the IAEA is now doing to improve PP practices around the world: Establish a global list of physical protection priorities; Create a multilateral security cooperation

    The Japan Atomic Energy Agency (JAEA) is submitting various types of accounting reports of international controlled materials to the Ministry of Education, Culture, Sports, Science, and Technology (MEXT) based on domestic laws and regulations. JAEA developed a comprehensive Nuclear Material Accountancy System to achieve uniform management of the data of each facility by using a company-wide database. Personal computers in each facility are connected throughout the company using an in-house network to create the comprehensive Nuclear Material Accountancy System. This System uses personal computers to facilitate timely communication and for easy maintenance and operation. Efficient data processing and quality control functions for accountancy reporting are also realized by this System. In addition, the System has the ability to extract and summarize data about Plutonium Management in the company for public announcement. This report introduces and describes the details and functions of this System. (author)

    This report presents details pertaining to an exercise conducted as part of the NKS-B programme using synthetic gamma ray spectra to simulate the type of data that may be encountered in the interception of material potentially containing special nuclear materials. A range of scenarios were developed involving sources that may or may not contain special nuclear materials. Gamma spectral data was provided to participants as well as ancillary data and participants were asked, under time constraint, to determine whether or not the data was indicative of circumstances involving special nuclear materials. The situations varied such that different approaches were required in order to obtain the correct result in each context. In the majority of cases participants were able to correctly ascertain whether or not the situations involved special nuclear material. Although fulfilling the primary goal of the exercise, some participants were not in a position to correctly identify with certainty the material involved, Situations in which the smuggled material was being masked by another source proved to be the most challenging for participants.

    The typical features of the GDR's nuclear material safeguards system are pointed out by analysing the nuclear material data reporting to the IAEA since 1972. Extent and consequences of the application of modern electronic data registration and processing methods at State and MBA levels are considered and an outlook is given for planned developments and extensions of the data processing system with a view to making the data exchange between the main users of nuclear material and the State control authority more effective and the work of the State control authority itself more efficient

  6. Strategic special nuclear material Inventory Differences. Semiannual report, April 1-September 30, 1984

    International Nuclear Information System (INIS)

    1985-07-01

    This sixteenth periodic semiannual report of Inventory Differences (ID) covers the last six months of fiscal year 1984 (April 1, 1984, through September 30, 1984), for the Department of Energy (DOE) and DOE contractor facilities possessing significant quantities of strategic special nuclear material (SSNM). Inventory Differences are simply the differences between the amount of material shown in the accounting records and the amount of material reported in the physical inventory. These differences are generally due to errors in estimating material in unmeasurable form at the time of an inventory, unmeasurable holdup in equipment, measurement imprecisions, inaccuracies in initial determinations of SSNM produced or used in nuclear reactors, and inventory or bookkeeping errors. Both DOE and contractors operating DOE facilities carefully maintain, analyze, and investigate ID data. Inventory Differences are expected in nuclear material processing and are not, in and of themselves, evidence of lost or stolen material. On the other hand, ID analysis provides valuable information on the effectiveness of the safeguards system's physical protection and material control measures as well as a check on the process controls and material management procedures. ID's outside safeguards control limits or involving a missing SSNM discrete item are investigated. If necessary, an operation may be shut down until an ID is resolved

  7. Active neutron technique for detecting attempted special nuclear material diversion

    The identification of special nuclear material (SNM) diversion is necessary if SNM inventory control is to be maintained at nuclear facilities. (Special nuclear materials are defined for this purpose as either 235 U of 239 Pu.) Direct SNM identification by the detection of natural decay or fission radiation is inadequate if the SNM is concealed by appropriate shielding. The active neutron interrogation technique described combines direct SNM identification by delayed fission neutron (DFN) detection with implied SNM detection by the identification of materials capable of shielding SNM from direct detection. This technique is being developed for application in an unattended material/equipment portal through which items such as electronic instruments, packages, tool boxes, etc., will pass. The volume of this portal will be 41-cm wide, 53-cm high and 76-cm deep. The objective of this technique is to identify an attempted diversion of at least 20 grams of SNM with a measurement time of 30 seconds

  8. Passive nondestructive assay of nuclear materials

    The term nondestructive assay (NDA) is applied to a series of measurement techniques for nuclear fuel materials. The techniques measure radiation induced or emitted spontaneously from the nuclear material; the measurements are nondestructive in that they do not alter the physical or chemical state of the nuclear material. NDA techniques are characterized as passive or active depending on whether they measure radiation from the spontaneous decay of the nuclear material or radiation induced by an external source. This book emphasizes passive NDA techniques, although certain active techniques like gamma-ray absorption densitometry and x-ray fluorescence are discussed here because of their intimate relation to passive assay techniques. The principal NDA techniques are classified as gamma-ray assay, neutron assay, and calorimetry. Gamma-ray assay techniques are treated in Chapters 1--10. Neutron assay techniques are the subject of Chapters 11--17. Chapters 11--13 cover the origin of neutrons, neutron interactions, and neutron detectors. Chapters 14--17 cover the theory and applications of total and coincidence neutron counting. Chapter 18 deals with the assay of irradiated nuclear fuel, which uses both gamma-ray and neutron assay techniques. Chapter 19 covers perimeter monitoring, which uses gamma-ray and neutron detectors of high sensitivity to check that no unauthorized nuclear material crosses a facility boundary. The subject of Chapter 20 is attribute and semiquantitative measurements. The goal of these measurements is a rapid verification of the contents of nuclear material containers to assist physical inventory verifications. Waste and holdup measurements are also treated in this chapter. Chapters 21 and 22 cover calorimetry theory and application, and Chapter 23 is a brief application guide to illustrate which techniques can be used to solve certain measurement problems

    1999-01-01

    The vulnerability analysis methodology developed for fixed nuclear material sites has proven to be extremely effective in assessing associated transportation issues. The basic methods and techniques used are directly applicable to conducting a transportation vulnerability analysis. The purpose of this paper is to illustrate that the same physical protection elements (detection, delay, and response) are present, although the response force plays a dominant role in preventing the theft or sabotage of material. Transportation systems are continuously exposed to the general public whereas the fixed site location by its very nature restricts general public access
