    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

    An accountancy system based on the Dynamic Materials Accountability (DYMAC) System has been in operation at the Plutonium Processing Facility at the Los Alamos Scientific Laboratory (LASL) since January 1978. This system, now designated the Plutonium Facility/Los Alamos Safeguards System (PF/LASS), has enhanced nuclear material accountability and process control at the LASL facility. The nondestructive assay instruments and the central computer system are operating accurately and reliably. As anticipated, several uses of the system have developed in addition to safeguards, notably scrap control and quality control. The successes of this experiment strongly suggest that implementation of DYMAC-based systems should be attempted at other facilities. 20 refs

    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 various inquiries can be carried out by the data base system which has free item searching procedure. (author)

  6. 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

    1979-01-01

    Techniques for analyzing the level of performance of nuclear materials accounting systems in terms of the four performance measures, total amount of loss, loss-detection time, loss-detection probability, and false-alarm probability, are presented. These techniques are especially useful for analyzing the expected performance of near-real-time (dynamic) accounting systems. A conservative estimate of system performance is provided by the CUSUM (cumulative summation of materials balances) test. Graphical displays, called performance surfaces, are developed as convenient tools for representing systems performance, and examples from a recent safeguards study of a nuclear fuels reprocessing plant are given. 6 refs

    We have adapted the Los Alamos MASS accounting system for use on an IBM PC/AT at the Fuels Manufacturing Facility (FMF) at Argonne National Laboratory-West (ANL-WEST) in Idaho Falls, Idaho. Cost of hardware and proprietary software was less than $10,000 per station. The system consists of three stations between which accounting information is transferred using floppy disks accompanying special nuclear material shipments. The programs were implemented in dBASEIII and were compiled using the proprietary software CLIPPER. Modifications to the inventory can be posted in just a few minutes, and operator/computer interaction is nearly instantaneous. After the records are built by the user, it takes 4 to 5 seconds to post the results to the database files. A version of this system was specially adapted and is currently in use at the FMF facility at Argonne National Laboratory in Idaho Falls. Initial satisfaction is adequate and software and hardware problems are minimal

  10. Augmented Automated Material Accounting Statistics System (AMASS)

    Lumb, R.F.; Messinger, M.; Tingey, F.H.

    1983-01-01

    This paper describes an extension of the AMASS methodology which was previously presented at the 1981 INMM annual meeting. The main thrust of the current effort is to develop procedures and a computer program for estimating the variance of an Inventory Difference when many sources of variability, other than measurement error, are admitted in the model. Procedures also are included for the estimation of the variances associated with measurement error estimates and their effect on the estimated limit of error of the inventory difference (LEID). The algorithm for the LEID measurement component uncertainty involves the propagated component measurement variance estimates as well as their associated degrees of freedom. The methodology and supporting computer software is referred to as the augmented Automated Material Accounting Statistics System (AMASS). Specifically, AMASS accommodates five source effects. These are: (1) measurement errors (2) known but unmeasured effects (3) measurement adjustment effects (4) unmeasured process hold-up effects (5) residual process variation A major result of this effort is a procedure for determining the effect of bias correction on LEID, properly taking into account all the covariances that exist. This paper briefly describes the basic models that are assumed; some of the estimation procedures consistent with the model; data requirements, emphasizing availability and other practical considerations; discusses implications for bias corrections; and concludes by briefly describing the supporting computer program

The actual application of the method to process data is emphasized

  12. A simulation model for material accounting systems

    International Nuclear Information System (INIS)

    Coulter, C.A.; Thomas, K.E.

    1987-01-01

    A general-purpose model that was developed to simulate the operation of a chemical processing facility for nuclear materials has been extended to describe material measurement and accounting procedures as well. The model now provides descriptors for material balance areas, a large class of measurement instrument types and their associated measurement errors for various classes of materials, the measurement instruments themselves with their individual calibration schedules, and material balance closures. Delayed receipt of measurement results (as for off-line analytical chemistry assay), with interim use of a provisional measurement value, can be accurately represented. The simulation model can be used to estimate inventory difference variances for processing areas that do not operate at steady state, to evaluate the timeliness of measurement information, to determine process impacts of measurement requirements, and to evaluate the effectiveness of diversion-detection algorithms. Such information is usually difficult to obtain by other means. Use of the measurement simulation model is illustrated by applying it to estimate inventory difference variances for two material balance area structures of a fictitious nuclear material processing line

    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

    The purpose of this study is to find an optimal blend between three safeguards systems for special nuclear material (SNM), the material accounting system and the physical security and material control systems. The latter two are denoted as principal deterrent systems. The optimization methodology employed is a two-stage decision algorithm, first an explicit maximization of expected diverter benefits and subsequently a minimization of expected defender costs for changes in material accounting procedures and incremental improvements in the principal deterrent systems. The probability of diverter success function dependent upon the principal deterrents and material accounting system variables is developed. Within the range of certainty of the model, existing material accounting, material control and physical security practices are justified

    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

    The Los Alamos Nuclear Material Accounting and Safeguards System (MASS) is a near-real-time accountability system for bulk materials, discrete items, and materials undergoing dynamic processing. MASS has evolved from a 80-column, card-based process control system to a very sophisticated computer system. Recently, the computer hardware was upgraded to a modern transaction oriented central computer system designed to accommodate extensive growth in the foreseeable future. The security of the MASS computer system is provided through various access controls. There are two kinds of access controls to be addressed. They are physical access control to the hardware which make up the system and access control to the software. There are many features which provide a measure of security to the hardware that are discussed. Access to the software is controlled by a security password. Access to various transaction activities in the system is controlled through the level of MASS under privilege. Details of MASS user privilege are discussed

    KAERI(Korea Atomic Energy Research Institute) has developed a nuclear material accountability system for DUPIC(Direct Use of Spent PWR Fuel in CANDU) fuel cycle process. The software development for the material accountability started with a general model software, so-called CoreMAS(Core Material Accountability System), at the beginning of 1998. The development efforts have been focused on the DUPIC safeguards system, and in addition, improved to meet Korean safeguards requirements under domestic laws and regulations. The software being developed as a local area network-based accountability system with multi-user environment is able to track and control nuclear material flow within a facility and inter-facility. In addition, it could be operated in a near-real time manner and also able to generate records and reports as necessary for facility operator and domestic and international inspector. This paper addresses DMAS(DUPIC Material Accountability System) being developed by KAERI and simulation in a small-scale DUPIC process for the verification of the software performance and for seeking further works

    The nuclear material safeguards system at the Portsmouth Gaseous Diffusion Plant is currently being improved. A new material control system will provide computerized monitoring and accountability, and a new physical protection system will provide upgraded perimeter and portal entry monitoring. The control system incorporates remote computer terminals at all processing, transfer and storage areas throughout the plant. Terminal equipment is interfaced to a computer through teletype equipment. A typical terminal transaction would require verification that the particular activity (material movement or process operation) is authorized, identifying the container involved, weighing the container, and then verifying the enrichment with non-destructive assay instrumentation. The system, when fully operational, will provide near real-time accountability for each eight-hour work shift for all items in process. (author)

    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)

    Pursuant to the domestic law and regulations revised in 1978 as to be conformed to the requirements specified in the Safeguards Agreement under the Non-Proliferation Treaty (NPT), the JAERI's system of nuclear material accountancy has been effectively developed. The system of accountancy in the JAERI is based on the information treatment by the computer. The data of nuclear material are retained batchwisely together with their complicate history reflected the inventory changes and other transactions. The reports represented these data are prepared and submitted to the IAEA through the Government every month. The inspections are frequently conducted to the JAERI to verify the material appeared in the reports. Item counting, item identification and non-destructive assay technique are brought to the verification. In some cases, seals of the Government and the IAEA are applied to the nuclear material at the inspections, as their containment measures. The surveillance camera is also installed in the facility to look whole view of reactor room and spent fuel pond. In this paper, the general safeguards application and its corresponding accountancy system on JAERI's nuclear facility are described. (author)

    Eggers, R.F.; Giese, E.W.; Kodman, G.P.

    1986-01-01

    The Automated Material Accounting Statistics System (AMASS) was developed under the sponsorship of the U.S. Nuclear Regulatory Commission. The AMASS was developed when it was realized that classical methods of error propagation, based only on measured quantities, did not properly control false alarm rate and that errors other than measurement errors affect inventory differences. The classical assumptions that (1) the mean value of the inventory difference (ID) for a particular nuclear material processing facility is zero, and (2) the variance of the inventory difference is due only to errors in measured quantities are overly simplistic. The AMASS provides a valuable statistical tool for estimating the true mean value and variance of the ID data produced by a particular material balance area. In addition it provides statistical methods of testing both individual and cumulative sums of IDs, taking into account the estimated mean value and total observed variance of the ID

    Modern approaches to nuclear materials safeguards have significantly increased the data processing needs of safeguards information systems. Implementing these approaches will require developing efficient, cost-effective designs. Guided by database design research, we are developing a design methodology for distributed materials control and accounting (MCandA) information systems. The methodology considers four design parameters: network topology, allocation of data to nodes, high-level global processing strategy, and local file structures to optimize system performance. Characteristics of system performance that are optimized are response time for an operation, timeliness of data, validity of data, and reliability. The ultimate goal of the research is to develop a comprehensive computerized design tool specifically tailored to the design of MCandA systems

    1975-01-01

    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

    The agreement between the government of Republic Of Korea (ROK) and the IAEA for the application of safeguards was signed and entered into force in 1975. The Additional Protocol (AP) to the Safeguards Agreement between the ROK and the IAEA was signed in 1999 and entered into force on 19 February 2004. Also, Implementation of Integrated Safeguards (IS) was started on 1 July, 2008 after a draw of the broader conclusion. The IAEA provides 2 hours notification for Random Interim Inspection (RII) under IS. For RII, the facility has to prepare the inspection documents in a short time. Therefore, KAERI (Korea Atomic Energy Research Institute) developed a new computerized nuclear material accounting system named KASIS (KAERI Safeguards Information treatment System) to treat the data by on-line for RII. For the efficient IS implementation, KAERI has a plan to upgrade the system to reflect the accounting approaches or reporting procedure according to facility characteristic. This paper describes the upgrade of the nuclear material accounting system and the efforts to reduce the burden of the facility operators

    The entry into force of the Verification Agreement in early 1977, linked to the wish to update the old Euratom System created in 1959, required that a new Euratom system (Community Regulation) be established. The main aspects of this new system, together with the practical experience gained in one and a half years operation, are presented. Certain basic accounting principles incorporated in the Euratom system, which are somewhat different from IAEA principles, are discussed in detail. This includes the notion of accounting date, some correction procedure aspects as well as the continuous updating of the book inventory to the physical reality in form of inventory changes. The effect of these differences when comparing IAEA and Euratom data is also mentioned. Furthermore, certain of the verifications carried out routinely on the operator's reports as well as on the reports submitted by Euratom to IAEA, are described and quantifications are given. Some mention is also made of areas where Euratom's role goes beyond that of the IAEA, i.e. the reporting implications of accounting for material by origin and control of particular use of the materials as well as verification of ore production and processing activities. Finally, improvements and simplifications concerning reports to the IAEA are proposed. (author)

    The objective is to upgrade Materials Control and Accountancy (MCandA) technology over the flows of special nuclear materials throughout the DOE complex of fuel cycles. The program focus is to develop a ''Management Tool'' for decision support in evaluating MCandA upgrades, and invalidating the MCandA aspects of the Master Safeguards and Security Agreements (MSSA) effectiveness. The approach is the computerization of the nuclear materials flow charts, identification of key measurement locations in the production and product fuel cycle, and construct data information processing at each measurement location. The program is to provide the Office of Safeguards and Security (OSS) with a timely management decision support system in planning MCandA safeguards technology upgrades over the nuclear materials production and product cycles

    The Nuclear Regulatory Authority (NRA) of Argentina has, among other functions, to ensure the fulfilment of national nuclear regulatory standards and all international safeguards commitments assumed by Argentina, particularly those related to the accounting and control of nuclear materials. To fulfil this responsibility, national inspections and audits of the operator's accounting and measurement systems are carried out, generating a great deal of data to be processed and evaluated. To manage this information in an efficient way, the RNA has implemented a control system composed by three database: SCMN, SIS and SOP, which interact amongst them. The objectives and functions of this integrated system and the achieved results to date are described in the present paper. (author)

    For the United States Nuclear Regulatory Commission, a procedure was developed and tested for the evaluation of Material Control and Accounting (MC and A) Systems at nuclear fuel facilities. This procedure, called the Structured Assessment Approach, SAA, subjects the MC and A system at a facility to a series of increasingly sophisticated adversaries and strategies. A fully integrated version of the computer codes which assist the analyst in this assessment will become available in October 1979. The concepts of the SAA and the results of the assessment of a hypothetical but typical facility are presented

    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

    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

  7. Criteria for Determination of Material Control and Accountability System Effectiveness

    International Nuclear Information System (INIS)

    2008-01-01

    The Nevada Test Site (NTS) is a test bed for implementation of the Safeguards First Principles Initiative (SFPI), a risk-based approach to Material Control and Accountability (MC and A) requirements. The Comprehensive Assessment of Safeguards Strategies (COMPASS) model is used to determine the effectiveness of MC and A systems under SFPI. Under this model, MC and A is divided into nine primary elements. Each element is divided into sub-elements. Then each sub-element is assigned two values, effectiveness and contribution, that are used to calculate the rating. Effectiveness is a measure of subelement implementation and how well it meets requirements. Contribution is a relative measure of the importance, and functions as a weighting factor. The COMPASS model provides the methodology for calculation of sub-element and element ratings, but not the actual criteria. Each site must develop its own criteria. For the rating to be meaningful, the effectiveness criteria must be objective and based on explicit, measurable criteria. Contribution (weights) must reflect the importance within the MC and A program. This paper details the NTS approach to system effectiveness and contribution values, and will cover the following: the basis for the ratings, an explanation of the contribution 'weights', and the objective, performance based effectiveness criteria. Finally, the evaluation process will be described

    The Safeguards Accountability Network (SAN) is a computerized on-line accountability system for the safeguards accountability control of nuclear materials inventories at Rocky Flats Plant. SAN is a dedicated accountability system utilizing source documents filled out on the shop floor as its base. The system incorporates double entry accounting and is developed around the Material Balance Area (MBA) concept. MBA custodians enter transaction information from source documents prepared by personnel in the process areas directly into the SAN system. This provides a somewhat near-real time perpetual inventory system which has limited interaction with MBA custodians. MBA custodians are permitted to inquire into the system and status items on inventory. They are also responsible for the accuracy of the accountability information used as input to the system for their MBA. Monthly audits by the Nuclear Materials Control group assure the timeliness and accuracy of SAN accountability information

  12. Structural properties of the material control and accounting system

    International Nuclear Information System (INIS)

    1978-12-01

    A unified digraph approach is proposed for the assessment of the structure of the MC and A System. The approach emphasizes the two structural aspects of the system: vulnerability and reliability. Vulnerability is defined as a possibility of loosing connectedness in a given structure due to line and/or node removals. It is purely deterministic notion which leads to a qualitative analysis of redundancy of connections in the corresponding system. Reliability of the MC and A System structure provides a more quantitative way of assessing how safe the system is to random failures of the links representing lines of communication, material paths, monitors, and the components of the power supply network. By assigning probabilities to the lines and nodes of the corresponding digraph, the least reliable path can be used as a measure of the goodness of the system, which can be computed by efficient shortest path algorithms. Both vulnerability and reliability considerations are important in determining the effect of tampering of an adversary with the elements of the MC and M System

    2008-01-01

    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

    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)

    Concepts on integration of physical protection and material accounting systems to enhance overall safeguards capability are developed and presented. These concepts identify ways in which material accounting systems can be used to enable effective monitoring of authorized movement of nuclear material through physical protection boundaries. Concepts are also discussed for monitoring user access to nuclear material and for tagging user identification to material accounting transactions through physical protection functions. These result in benefits in detecting diversion and in positively tracing material movement. Finally, coordination of safeguards information from both subsystems in such an integrated system through a safeguards coordination center is addressed with emphasis on appropriate response in case of discrepancies

The system is also used to monitor and evaluate the use of the nuclear material inventory against programmatic objectives for materials management. The SAN system utilizes two Harris 800 Computers as central processing units. Enhancement plans are currently being formulated to provide automated data collection from process operations on the shop floor and from non-destructive analysis safeguards instrumentation. SAN, discussed in this paper, is an excellent system for basic accountability control of nuclear materials inventories and is a quite useful tool in evaluating the efficient use of nuclear materials inventories at Rocky Flats Plant

    2003-01-01

    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

    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.)

    Since 1996, the Mining and Chemical Combine (MCC - formerly known as K-26), and the United States Department of Energy (DOE) have been cooperating under the cooperative Nuclear Material Protection, Control and Accounting (MPC&A) Program between the Russian Federation and the U.S. Governments. Since MCC continues to operate a reactor for steam and electricity production for the site and city of Zheleznogorsk which results in production of the weapons grade plutonium, one of the goals of the MPC&A program is to support implementation of an expanded comprehensive nuclear material control and accounting (MC&A) program. To date MCC has completed upgrades identified in the initial gap analysis and documented in the site MC&A Plan and is implementing additional upgrades identified during an update to the gap analysis. The scope of these upgrades includes implementation of MCC organization structure relating to MC&A, establishing material balance area structure for special nuclear materials (SNM) storage and bulk processing areas, and material control functions including SNM portal monitors at target locations. Material accounting function upgrades include enhancements in the conduct of physical inventories, limit of error inventory difference procedure enhancements, implementation of basic computerized accounting system for four SNM storage areas, implementation of measurement equipment for improved accountability reporting, and both new and revised site-level MC&A procedures. This paper will discuss the implementation of MC&A upgrades at MCC based on the requirements established in the comprehensive MC&A plan developed by the Mining and Chemical Combine as part of the MPC&A Program.

    The current status of the LLL program for MC and A system assessment is reviewed. Particular emphasis is given to the assessment procedure and results. The integrated approach we have taken includes many of the functions normally assigned to physical security. Deceit and tampering are explicitly considered. The results of such a detailed assessment include a systematic identification of adversary targets; the most vulnerable portions of the safeguards system; the number and type of adversaries required, in collusion, to fail the system; and the conditional probabilities of safeguard system failure for a variety of assumptions. The assessment procedure was demonstrated by analyzing a prototype fuel cycle facility, the Test Bed. We believe our methodology will be useful to the NRC as a means of performing detailed, objective assessments. The nuclear industry also should find it valuable as a design tool

    Most physical security functions can be accomplished by a range of alternative features. Careful design can provide comparable levels of security regardless of which option is chosen, albeit with possible differences in cost and efficiency. However, the effectiveness and especially the cost and efficiency of the material control and accounting system may be strongly influenced by the selection of a particular design approach to physical security. In this paper, a series of examples are cited to illustrate the effects that particular physical protection design choices may have. The examples have been chosen from several systems engineering projects at facilities within the DOE nuclear community. These examples are generalized, and a series of design principles are proposed for integrating physical security with material control and accounting by appropriate selection of alternative features. 2 references, 6 figures

    The application NucMAS provides basic computerized accountability functions for the Savannah River Plant (SRP) Separations Department Material Balance Areas (MBA's). These functions include data entry, data management, calculations, and report generation. NucMAS can be used both for routine reporting to the SRP central Material Control and Accounting (MC and A) system and for rapid ad hoc queries in emergency situations. The system is designed to work with any process handling one or more of the 17 accountable nuclear materials specified by the Department of Energy (DOE). It relies on user-supplied configuration data to drive data prompts, report headings, data validations, and calculations

    2014-01-01

    The Integrated Safeguards (IS) has been applied to 10 nuclear facilities and 1 location outside facility (LOF) at the Korea Atomic Energy Research Institute (KAERI) since July 2008. One of the major changes in the implementation of safeguards under the IS is to apply the concept of a Random Interim Inspection (RII) instead of an interim inspection. The RII plan is notified within a few hours under the IS. It is thus difficult for facility operators to prepare the inspection documents within a short time if they do not periodically manage and process the nuclear material accounting data at each facility. To resolve these issues, KAERI developed a Web-based accounting system with the function of a near real-time accounting (NRTA) system to effectively and efficiently manage the nuclear material accounting data produced at the nuclear facilities and cope with a short notice inspection under the IS, called KASIS (KAeri Safeguards Information treatment System). The facility operators must input the accounting data on the inventory changes, which are the transfers of nuclear materials among the nuclear facilities and the chemical/physical composition changes, into the KASIS. KAERI also established an RFID system for controlling and managing the transfer of nuclear material and/or radioactive materials between the nuclear facilities for the purpose of nuclear safety management, and developed the nuclear material accounting system with the functions of inventory management of nuclear material at the facility level

    The Integrated Safeguards (IS) has been applied to 10 nuclear facilities and 1 location outside facility (LOF) at the Korea Atomic Energy Research Institute (KAERI) since July 2008. One of the major changes in the implementation of safeguards under the IS is to apply the concept of a Random Interim Inspection (RII) instead of an interim inspection. The RII plan is notified within a few hours under the IS. It is thus difficult for facility operators to prepare the inspection documents within a short time if they do not periodically manage and process the nuclear material accounting data at each facility. To resolve these issues, KAERI developed a Web-based accounting system with the function of a near real-time accounting (NRTA) system to effectively and efficiently manage the nuclear material accounting data produced at the nuclear facilities and cope with a short notice inspection under the IS, called KASIS (KAeri Safeguards Information treatment System). The facility operators must input the accounting data on the inventory changes, which are the transfers of nuclear materials among the nuclear facilities and the chemical/physical composition changes, into the KASIS. KAERI also established an RFID system for controlling and managing the transfer of nuclear material and/or radioactive materials between the nuclear facilities for the purpose of nuclear safety management, and developed the nuclear material accounting system with the functions of inventory management of nuclear material at the facility level.

    This paper gives an overview of DYMCAS, the material control and accountability information system for the Y-12 National Security Complex. A common misconception, even within the DOE community, understates the nature and complexity of material control and accountability (MC and A) systems, likening them to parcel delivery systems tracking packages at various locations or banking systems that account for money, down to the penny. A major point set forth in this paper is that MC and A systems such as DYMCAS can be and often are very complex. Given accountability reporting requirements and the critical and sensitive nature of the task, no MC and A system can be simple. The complexity of site-level accountability systems, however, varies dramatically depending on the amounts, kinds, and forms of nuclear materials and the kinds of processing performed at the site. Some accountability systems are tailored to unique and highly complex site-level materials and material processing and, consequently, are highly complex systems. Sites with less complexity require less complex accountability systems, and where processes and practices are the same or similar, sites on the mid-to-low end of the complexity scale can effectively utilize a standard accountability system. In addition to being complex, a unique feature of DYMCAS is its integration with the site production control and manufacturing system. This paper will review the advantages of such integration, as well as related challenges, and make the point that the effectiveness of complex MC and A systems can be significantly enhanced through appropriate systems integration

    The 34 nuclear facilities, including the nuclear power plants, were on operating in Korea and the Technology Center for Nuclear Control(TCNC) has been submit the nuclear material accounting reports to the government and IAEA. At the start point of this work, all reports were controlled via manually and at now, they were controlled based on the client/server system. The fast progress of the computer and internet communication changes the environment of computing from disk operating system to web based system using internet. So, a new system to access the safeguards information and nuclear material accounting system more convenient was needed. In this thesis, a safeguards information control system including the nuclear material accounting reports at the state level based on the web was designed. The oracle RDBMS (Relational Data Base Management System) was adopted for data base management. And all users can access this program via inter-net using their own computer

    The implementation of nuclear forensics requires physical, chemical and radiological characteristics with transport history to unravel properties of seized nuclear materials. For timely assessment provided in the ITWG guideline, development of national response system (e.g., national nuclear forensic library) is strongly recommended. Nuclear material accounting is essential to obtain basic data in the nuclear forensic implementation phase from the perspective of nuclear non-proliferation related to the IAEA Safeguards and nuclear security. In this study, the nuclear material accounting reports were chosen due to its well-established procedure, and reviewed how to efficiently utilize the existing material accounting system to the nuclear forensic implementation phase In conclusion, limits and improvements in implementing the nuclear forensics were discussed. This study reviewed how to utilize the existing material accounting system for implementing nuclear forensics. Concerning item counting facility, nuclear material properties can be obtained based on nuclear material accounting information. Nuclear fuel assembly data being reported for the IAEA Safeguards can be utilized as unique identifier within the back-end fuel cycle. Depending upon the compulsory accountability report period, there exist time gaps. If national capabilities ensure that history information within the front-end nuclear fuel cycle is traceable particularly for the bulk handling facility, the entire cycle of national nuclear fuel would be managed in the framework of developing a national nuclear forensic library

    1996-07-01

    DOE facilities rely increasingly on computerized systems to manage nuclear materials accountability data and to protect against diversion of nuclear materials or other malevolent acts (e.g., hoax due to falsified data) by insider threats. Aspects of modern computerized material accountability (MA) systems including powerful personal computers and applications on networks, mixed security environments, and more users with increased knowledge, skills and abilities help heighten the concern about insider threats to the integrity of the system. In this paper, we describe a methodology for assessing MA applications to help decision makers identify ways of and compare options for preventing or mitigating possible additional risks from the insider threat. We illustrate insights from applying the methodology to local area network materials accountability systems

    1976-01-01

    The internal accounting system of the Fabrication and Radiometallurgical Inspection Service (SFER) is basically designed to meet national and international requirements for nuclear materials accountancy as applied to feed materials. The authors discuss the principles underlying this accounting system for the case of the Plutonium Fuel Assembly Fabrication Complex at Cadarache. The sphere of application of the system covers more than 200 work stations and approximately 100 different materials. Some 20000 movements of feed materials per year represent transfers of a cumulative mass much greater than one ton of fissile material. A data processing system has therefore become essential in order to ensure the rapid and reliable acquisition of accounting data relating to these movements. The authors describe the system (definition of stations and material codes, description of supporting facilities used) and discuss the mode of acquisition with particular reference to relative speed of action. In conclusion, the authors indicate that the system offers interesting possibilities, in addition to its original purpose, in the following areas: Preparation of material balances; compliance with safety regulations to avert the risk of criticality; discouragement of possible diversion.

    1995-01-01

    The Los Alamos Safeguards Systems Group's Materials Accounting With Sequential Testing (MAWST) computer program was developed to fulfill DOE Order 5633.3B requiring that inventory-difference control limits be based on variance propagation or any other statistically valid technique. Westinghouse Savannah River Company (WSRC) developed a generic computerized accountability system, NucMAS, to satisfy accounting and reporting requirements for material balance areas. NucMAS maintains the calculation methods and the measurement information required to compute nuclear material transactions in elemental and isotopic masses by material type code. The Safeguards Systems Group designed and implemented to WSRC's specifications a software interface application, called NucMASloe. It is a layered product for NucMAS that automatically formats a NucMAS data set to a format compatible with MAWST and runs MAWST. This paper traces the development of NucMASloe from the Software Requirements through the testing and demonstration stages. The general design constraints are described as well as the difficulties encountered on interfacing an external software product (MAWST) with an existing classical accounting structure (NucMAS). The lessons learned from this effort, the design, and some of the software are directly applicable to the Local Area Network Material Accountability System (LANMAS) being sponsored by DOE

  1. Overview of an automated, near realtime materials accounting system in use at the Savannah River Plant

    International Nuclear Information System (INIS)

    Clark, W.C. Jr.

    1987-01-01

    A reliable material accounting system is a requirement for the operation of any nuclear facility. At the Savannah River Plant, an automated, near realtime, accounting system has been developed to provide such reliability. The system's design provides timely detection of diversion or accounting problems by monitoring the activity in 18 unit process areas (UPAs). Material balance calculations are performed for each UPA after a batch of material has completed a processing step. In most cases, an inventory difference (ID) for a UPA is established at least every 24 hours. Detection of an accounting problem is further enhanced by an online measurement control program. This program evaluates the performance of most measurement equipment every 12 hours. Error estimates are propagated when a material balance is closed to provide a realtime limit of error for the inventory difference. To minimize false alarms, the data must be reliable and free of input errors. Solution volumes, container identifications, material weights, etc., are all collected via direct computer connections. Manual data input is used only as a backup to the automated system. Automatic data collection also provides a quick and easy method of entering accounting data. Data entry is therefore performed simultaneously with production operations, without reducing throughput. Finally, requests for analytical results required to determine nuclear material concentrations are made online. Concentrations are determined using one of ten assay devices or by analysis performed in a dedicated laboratory. When results are available, the information is posted on the accounting computer and any required adjustments are performed automatically. If necessary, material balances are reclosed to reflect the ID changes caused by a posted results

    Since August 1994 Kurchatov Institute in cooperation with several US Department of Energy Laboratories has been developing a site-wide computerized material accounting system for nuclear materials. In 1994 a prototype system was put into trial operation at two Kurchatov facilities. Evaluation of this prototype led to the development of a new computerized material accounting system named KI-MACS, which has been operational since 1996. This system is a site-wide local secure computer network with centralized database capable of dealing with strictly confidential data and performing near-real time accountancy. It utilizes a Microsoft Windows NT operating system with SQL Server and Visual Basic, and has a `star`-like network architecture. KI-MACS is capable of dealing with materials in itemized and bulk form, and can perform statistical evaluations of measurements and material balance. KI-MACS is fully integrated with bar code equipment, electronic scales, gamma-ray spectrometers and an Active Well Coincidence Counter, thus providing almost on-line evaluation and utilization of results of measurements, item identification and accounting. At present KI-MACS is being used in Physical Inventory Taking at the Kurchatov Central Storage Facility, and by the end of 1997 will be installed at twelve Kurchatov nuclear facilities.

    Most physical security functions can be accomplished by a range of alternative features. Careful design can provide comparable levels of security regardless of which option is chosen, albeit with possible differences in cost and efficiency. However, the effectiveness and especially the cost and efficiency of the material control and accounting system may be strongly influenced by the selection of a particular design approach to physical security. In this paper, a series of examples are cited to illustrate the effects that particular physical protection design choices may have. The examples have been chosen from several systems engineering projects at facilities within the DOE nuclear community. These examples are generalized, and a series of design principles are proposed for integrating physical security with MC and A by appropriate selection of alternative features

    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

    The accounting system based on data filing and inquiry processing by the use of an optical mark reader (OMR) has been developed and operated satisfactorily for criticality control and accountancy of nuclear materials in the plutonium facilities of the Power Reactor and Nuclear Fuel Development Corporation (PNC). The OMR system has merits, especially compared with an old chit and punch-card system, such as low cost, abundance of the data included on a single sheet, universality of use for all kinds of material transfers, ease of data correction, and a large capacity. The OMR system is applied to the material transfer and also for physical inventory taking. This system, together with the use of an accurate automatic balance equipped at each glove box, which is generally designated as an accounting unit for the criticality control, generated a MUF of 0.43% for a fuel fabrication campaign of 119 assemblies for a fast reactor, which can be decreased further. In relation to the recent safeguarding situation and also to fitting in with an automatic fuel fabrication process, however, a further development of the present system will be necessary in the near future. This future system is discussed with reference to criticism of the current accountancy system by Rosenbaum and others, and its possible framework with the emphasis on the weighing and reading of numbered items is suggested.

    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 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)

    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.

A preliminary web-based information system is thus developed to analyze the issues of resource consumption and waste generation, enabling countries to manage resources and wastes from a life cycle perspective. This pioneering system features a four-layer framework that integrates information on physical flows and economic activities with material flow accounting and waste input–output table analysis. Within this framework, several applications were developed for different waste and resource management stakeholders. The hierarchical and interactive dashboards allow convenient overview of economy-wide material accounts, waste streams, and secondary resource circulation. Furthermore, the system can trace material flows through associated production supply chain and consumption activities. Integrated with economic models; this system can predict the possible overloading on the current waste management facility capacities and provide decision support for designing strategies to approach resource sustainability. The limitations of current system are specified for directing further enhancement of functionalities.

    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.

    A facility in which nuclear materials are handled maintains a facility system of accounting for and control of nuclear material. Such a system contains, as one of key elements, a record and report system. This record and report information system is a rather complex one because it needs to conform to various requirements from the national or international safeguards authorities and from the plant operator who has to achieve a safe and economical operation of the plant. Therefore it is mandatory to computerize such information system. The authors have reviewed these requirements and standardized the book-keeping and reporting procedures in line with their computerization. On the basis of this result the authors have developed a computer system, FARMS, named as an acronym of standardized facility record and report model system, mainly reflecting the requirements from the national and international safeguards authorities. The development of FARMS has also been carried out as a JASPAS - Japan Support Programme for Agency Safeguards - project since 1985 and the FARMS code was demonstrated as an accountancy tool in the regional SSAC training courses held in Japan in 1985 and 1987. This report describes the standardization of a record and report system at the facility level, its computerization as a model system and the demonstration of the developed system, FARMS. (author)

    RBU had already started in 1976 with the computerisation of its nuclear material accountancy system. It used the hardware and the software which were at hand at that time. The development of the software needed about 3 years, and so, the system, was fully introduced in 1979 and has been used since then with only minor changes. But with the time, the overwhelming progress in computer and software technology has overcome the existing system. Upgrading the old system would need a lot of effort, so RBU decided to modernize its system fundamentally. In the time between RBU has developed a quality record and documentation system for the purposes of quality assurance and quality control. This system shall be enlarged, so that it can overtake the tasks of NMA, too. The quality record system contains already nearly 80 % of all NMA-relevant data. The presented paper will describe the main changes between the present and the future system

    Nuclear facilities that handle and process nuclear materials are required to track their nuclear holdings and to keep adequate records that manage and control the inventory of those holdings. The complexity of a system that does this job is directly proportional to the complexity of the facility's operations. This paper describes an approach to computerized materials protection, control, and accountability (MPC and A) that was introduced by Los Alamos National Laboratory (LANL) in the fall of 1997. This new system, E/Z MAS, is the latest addition to the LANL suite of computerized MPC and A tools, which also includes the CoreMAS system. E/Z MAS was initially designed to address the needs of those facilities that have small to modest MPC and A needs but has been expanded to provide full functionality for any facility. The system name, E/Z MAS, reflects the system's easy-to-use characteristics, which include ease of installation and ease of software maintenance. Both CoreMAS and E/Z MAS have been provided to facilities in the Former Soviet Union to assist them in implementing a computerized MPC and A system that meets their needs. In this paper the authors will address the functionality of CoreMAS and E/Z MAS, and an argument in favor of intranet-based material control and accountability will be advanced

  15. A Computer Simulation to Assess the Nuclear Material Accountancy System of a MOX Fuel Fabrication Facility

    SimMOX is a computer programme that simulates container histories as they pass through a MOX facility. It performs two parallel calculations: · the first quantifies the actual movements of material that might be expected to occur, given certain assumptions about, for instance, the accumulation of material and waste, and of their subsequent treatment; · the second quantifies the same movements on the basis of the operator's perception of the quantities involved; that is, they are based on assumptions about quantities contained in the containers. Separate skeletal Excel computer programmes are provided, which can be configured to generate further accountancy results based on these two parallel calculations. SimMOX is flexible in that it makes few assumptions about the order and operational performance of individual activities that might take place at each stage of the process. It is able to do this because its focus is on material flows, and not on the performance of individual processes. Similarly there are no pre-conceptions about the different types of containers that might be involved. At the macroscopic level, the simulation takes steady operation as its base case, i.e., the same quantity of material is deemed to enter and leave the simulated area, over any given period. Transient situations can then be superimposed onto this base scene, by simulating them as operational incidents. A general facility has been incorporated into SimMOX to enable the user to create an ''act of a play'' based on a number of operational incidents that have been built into the programme. By doing this a simulation can be constructed that predicts the way the facility would respond to any number of transient activities. This computer programme can help assess the nuclear material accountancy system of a MOX fuel fabrication facility; for instance the implications of applying NRTA (near real time accountancy).

    The Systems Analysis for Material Control and Accountancy Technology (SAMCAT) is a program to develop an interactive computer-based management system for decision support in evaluating Material Control and Accountancy (MCandA) upgrades and for validating the MCandA aspects of the Master Safeguards and Security Agreements (MSSA) effectiveness. This paper briefly reviews SAMCAT and presents the status of current activities, with primary focus on the design of a pilot study that has been planned for the near-term development program. The objective of the pilot study is to aid in the development and testing of assessment technologies by utilizing data and information from recent upgrades in MCandA measurements at several of the measurement locations that were important contributors to the uncertainty of the inventory differences (IDs) for a specific material balance area (MBA). The FB-Line MBA in the plutonium production cycle through Savannah River was recommended as a candidate MBA for the study. Attributes considered as selection criteria of key measurement locations for MCandA upgrades, importance rankings of the measurement locations, modeling approaches in evaluating the effectiveness of upgrades at given locations, and the data requirements to support the pilot study are presented. Applications of the near-term pilot study to the overall SAMCAT development program are also presented. 2 refs., 3 figs., 1 tab

    1995-01-01

    The operation of the Fuel conditioning Facility (FCF) is based on the electrometallurgical processing of spent metallic reactor fuel. It differs significantly, therefore, from traditional PUREX process facilities in both processing technology and safeguards implications. For example, the fissile material is processed in FCF only in batches and is transferred within the facility only as solid, well-characterized items; there are no liquid steams containing fissile material within the facility, nor entering or leaving the facility. The analysis of a single batch lends itself also to an analytical relationship between the safeguards criteria, such as alarm limit, detection probability, and maximum significant amount of fissile material, and the accounting system's performance, as it is reflected in the variance associated with the estimate of the inventory difference. This relation, together with the sensitivity of the inventory difference to the uncertainties in the measurements, allows a thorough evaluation of the power of the accounting system. The system for the accountancy of the fissile material in the FCF has two main components: a system to gather and store information during the operation of the facility, and a system to interpret this information with regard to meeting safeguards criteria. These are described and the precision of the inventory closure over one batch evaluated

    Nearly all facilities that store hazardous (radioactive or non-radioactive) materials must comply with prevailing federal, state, and local laws. These laws usually have components that require periodic physical inspections to insure that all materials remain safely and securely stored. The inspections are generally labor intensive, slow, put personnel at risk, and only find anomalies after they have occurred. The system described in this paper was developed for monitoring stored nuclear materials resulting from weapons dismantlement, but its applications extend to any storage facility that meets the above criteria. The traditional special nuclear material (SNM) accountability programs, that are currently used within most of the Department of Energy (DOE) complex, require the physical entry of highly trained personnel into SNM storage vaults. This imposes the need for additional security measures, which typically mandate that extra security personnel be present while SNM inventories are performed. These requirements increase labor costs and put additional personnel at risk to radiation exposure. In some cases, individuals have received radiation exposure equivalent to the annual maximum during just one inventory verification. With increasing overhead costs, the current system is rapidly becoming too expensive to operate, the need for an automated method of inventory verification is evident. The Continuous Automated Vault Inventory System (CAVIS) described in this paper was designed and prototyped as a low cost, highly reliable, and user friendly system that is capable of providing, real-time weight, gamma. and neutron energy confirmation from each item stored in a SNM vault. This paper describes the sensor technologies, the CAVIS prototype system (built at Y- 12 for highly enriched uranium storage), the technical requirements that must be achieved to assure successful implementation, and descriptions of sensor technologies needed for a plutonium facility.

    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

    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.)

    1985-02-01

    The purpose of this document is to provide a detailed description of the technical elements of a system for the accounting for and control of nuclear material at the State Authority level which can be used by a state in the establishment of a national system for nuclear material accounting and control. It is expected that a state system designed along the lines described also will assist the IAEA in carrying out its safeguards responsibilities. The scope of this document is limited to descriptions of the technical elements of a state level system concerned with Laws and Regulations, the Information System, and the Establishment of Requirements for Nuclear Material Accounting and Control. The discussion shows the relationship of these technical elements at the state level to the principal elements of an SSAC at the facility levels

    An assessment was done on the potential capability of a Near-Real-Time materials accountancy system for a model plutonium conversion plant. To this end, a computer simulation system, DYSAS-C, has been developed and evaluated through this assessment study. This study showed that N.R.T.A system could be used not only as a good operator's accounting system but also as a useful inspectorate's system to detect an abrupt diversion. It also showed, however, that more elaborated NRTA system which have not yet evaluated in this study should be considerered when we wish to improve of detecting protracted diversion. (author)

    The Westinghouse Hanford company (Westinghouse Hanford) and the Los Alamos National Laboratory (LANL) have undertaken a joint effort to develop a new generation material accounting system. The system will incorporate the latest advances in microcomputer hardware, software, and network technology. This system, the Local Area Network Material Accounting System (LANMAS), offers greater performance and functionality at a reduced overall cost. It also offers the possibility of establishing a standard among DOE and NRC facilities for material accounting. This report provides a discussion of this system

    1988-01-01

    The Department of Energy's (DOE) Material Control and Accountability (MC and A) Orders were revised during this past year. The primary focus of the revision process was to eliminate any policy gaps that existed between current orders and the standards and criteria and to examine current policy where questions of completeness or effectiveness may be of concern. The MC and A Subtask Group identified the following three major areas for change: (1) the need to expand the graded safeguards concept; (2) the need to provide for defense in depth; and (3) the need to include system performance requirements. Operational and cost impacts were of primary consideration in these changes. The subtask group accomplished its goal as directed and within the required time frames. The revision process benefitted tremendously from the earlier works of the numerous standards and criteria committees and the Operation Cerberus Committees

    1994-01-01

    Large amounts of safeguards data are automatically gathered and stored by monitoring instruments used in nuclear chemical processing plants, nuclear material storage facilities, and nuclear fuel fabrication facilities. An integrated safeguards approach requires the ability to identify anomalous activities or states in these data. Anomalies in the data could be indications of error, theft, or diversion of material. The large volume of the data makes analysis and evaluation by human experts very tedious, and the complex and diverse nature of the data makes these tasks difficult to automate. This paper describes the early work in the development of analysis tools to automate the anomaly detection process. Using data from accounting databases, the authors are modeling the normal behavior of processes. From these models they hope to be able to identify activities or data that deviate from that norm. Such tools would be used to reveal trends, identify errors, and recognize unusual data. Thus the expert's attention can be focused directly on significant phenomena

  19. Sequential game-theoretical analysis of safeguards systems based on the principle of material accountability

    International Nuclear Information System (INIS)

    Abel, V.; Avenhaus, R.

    1981-01-01

    The international control of fissile material used in nuclear technology is based on the principle of material accountability, i. e. on the difference between book inventory and physical inventory of a plant at the end of an inventory period. Since statistical measurement errors cannot be avoided, this comparison calls for methods of statistical hypotheses testing. Moreover, game-theoretical methods are needed as an analytical tool, since if the plant operator wilfully diverts material he will do so in an optimal manner. In this article, the optimal test strategy is determined for the case of two inventory periods. Two assumptions are made: The operation of the plant is stopped after the first inventory period if the test indicates wilful diversion, and the plant operator chooses the probability of wilfully diverting material for both inventory periods before the start of the first period. The assertions which depend on the payoff parameters and the substitutes which must be given in the case that the payoff parameters cannot be estimated are discussed. (orig.) [de

  20. The problem of material accountancy. Difference between the international material accountancy and the Japanese material accountancy

    2001-01-01

    It has been 30 years since the development of SSAC (State's system of Accounting for and Control of nuclear material) of Japan began. Moreover, 24 years have been passed after SSAC was employed. The maintenance on the law for carrying out SSAC in the meantime also progressed, and the system of SSAC has also been established favorably. However, new correspondence was internationally called for about the safeguards for reprocessing facilities or uranium enrichment facilities, and innovative safeguards concepts like NRTA or LFUA were developed. The LASCAR (Large Scale Reprocessing Plant Safeguards) forum was held on the safeguards for a large scale reprocessing facility, and international agreement on the safeguards was progressed. When we look back upon the history of such safeguards development in recent years, most people can see little problem on the contents of the national safeguards system itself. As the history shows, however, the passive approach has been taken in developing the Japanese safeguards system. We have always tried to seek a solution on the basis 'What is the minimum requirement in order to receive international safeguards.' Now, the nuclear fuel cycle of Japan has reached the maximum scale in the world. To Japan which promotes commercial use of plutonium, the world community is supervising this severely. Under such a situation it is no doubt that passive safeguards correspondence can no longer be allowed. The author thinks that it is coming when the old nuclear management system completed based on a passive attitude should be improved. What should an active nuclear material management system be? In this presentation, the author wishes to explore the clue to it. (author)

    1986-09-01

    An IBM-PC and compatible based state system of accounting for and control of nuclear materials under international safeguards (state-level SSAC) is presented. The system works under DOS version 2.0 and above. It consists of a single-module Safeguards Report Editor which is a multi-function menu-driven code written in BASIC. The Editor may be run both in interactive mode and as an EXEC module. The output represents four types of material accounting reports on diskette, suitable for direct input into the IAEA Safeguards Information System (ISIS). In the first part of the report presented, a general description of the system is given. This is complemented with a detailed User Manual where a Guide to Applications, an Operator's Guide, a Programmer's Guide and Listings are included. The system is now available. It is maintained by the Bulgarian Committee on the Uses of Atomic Energy for Peaceful Purposes

    Department of Energy and Nuclear Regulatory Commission regulations governing material control and accountability in nuclear facilities have become more restrictive in the past decade, especially in areas that address the insider threat. As the insider threat receives greater credibility, regulations have been strengthened to increase the probability of detecting insider activity and to prevent removal of a significant quantity of Special Nuclear Material (SNM) from areas under control of the protective force

    There are 5 NPPs with 14 operating units in Ukraine as well as scientific facilities which are all under the IAEA safeguards. Although a number of important state laws concerning the use of nuclear energy and radiation safety there are still problems on computer processing of current information on accounting and control. The Y2K problem exists in relation to control and operating systems. Ukraine is ready to accept any recommendations in order to eliminate this problem. Some working groups were organised for solving the Y2K problem, each starting from different directions towards the common aim

    1985-01-01

    High altitude nuclear bursts generate extremely short and large magnitude electromagnetic pulses (EMP). Electronic circuits which are commonly used nowadays are directly threatened by such an effect. This effect is so important that it has the characteristic to cover large areas, as large as a whole country. For an equipment or a system to stand against such an electromagnetic threat without being considerably disturbed, it is advised to take into account particular protections from the outset of the design phase and during the production phase, that is to say to ensure its hardening. Taking into account and ensuring the EMP protection of an equipment or a system, the Telecommunications Division (DTC) of Thomson-CSF has been devoting to for a number of years. The experience acquired through various studies and production work has allowed a thorough definition of the main steps required in an EMP hardening task: - hardening goal definition; - hardening study and design; - hardening carrying out; - design and production of EMP environment simulators; - hardening validation; - maintenance. This paper describes for each one of these steps: - which approach is undertaken; - which questions are raised; - which documents to constitute [fr

    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. The concentration of analytical and administrative

    In September 1977 a Task Force was formed to complete a study of the role of material control and material accounting in NRC's safeguards program. The Task Force's assignment was to: define the roles and objectives of material control and material accounting in the NRC safeguards program; recommend goals for the material control and material accounting systems based on their roles and objectives; assess the extent to which the existing safeguards regulatory base meets or provides the capability to meet the recommended goals; and provide direction for material control and material accounting development, including both near-term and long-term upgrades. The study was limited to domestic nuclear facilities possessing significant amounts of plutonium, uranium-233 or highly enriched uranium in unsealed form. The Task Force findings are reported

    1999-01-01

    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

    1983-01-01

    The paper sets forth the basic principles underlying nuclear material accounting at nuclear power plants with WWER-440 reactors. It briefly describes the general structure and individual units in a program for computerized accounting. The use of this program is illustrated by the actual accounting data from the fifth unit of the Novovoronezh nuclear power station. The NUMIS program seems to be of interest both for the purposes of IAEA safeguards and for nuclear power plant operators in countries where power plants with WWER-440 reactors subject to IAEA safeguards are either in operation or under construction. The research in question was conducted initially under an IAEA research contract; the system is now being developed further and tested under the IAEA-USSR technical and scientific co-operation programme on safeguards.

    Pillay, K.K.S. (comp.)

    1989-04-01

    Materials accounting is essential to providing the necessary assurance for verifying the effectiveness of a safeguards system. The use of measurements, analyses, records, and reports to maintain knowledge of the quantities of nuclear material present in a defined area of a facility and the use of physical inventories and materials balances to verify the presence of special nuclear materials are collectively known as materials accounting for nuclear safeguards. This manual, prepared as part of the resource materials for the Safeguards Technology Training Program of the US Department of Energy, addresses fundamental aspects of materials accounting, enriching and complementing them with the first-hand experiences of authors from varied disciplines. The topics range from highly technical subjects to site-specific system designs and policy discussions. This collection of papers is prepared by more than 25 professionals from the nuclear safeguards field. Representing research institutions, industries, and regulatory agencies, the authors create a unique resource for the annual course titled ''Materials Accounting for Nuclear Safeguards,'' which is offered at the Los Alamos National Laboratory.

    A radiometric method of determining the inventory of an operating plutonium plant is described. An array of total neutron counters distributed across the plant is used to estimate hold-up at each plant item. Corrections for the sensitivity of detectors to plutonium in adjacent plant items are achieved through a matrix approach. This paper describes our experience in design, calibration and operation of a Plutonium Inventory Measurement System (PIMS) on an oxalate precipitation plutonium finishing line. Data from a recent trial of Near-Real-Time Materials Accounting (NRTMA) using the PIMS are presented and used to illustrate its present performance and problem areas. The reader is asked to consider what role PIMS might have in future accountancy systems

    Jenkins, J.D.; McNeany, S.R.; Rushton, J.E.

    1975-07-01

    The conceptual design of the fissile material assay and accountability system for the HTGR refabrication pilot plant has been established. The primary feature affecting the design is the high, time varying, gamma activity of the process material due to the unavoidable presence of uranium-232. This imposes stringent requirements for remote operation and remote maintainability of system components. At the same time, the remote operation lends itself to implementation of an automated data collection and processing system for real-time accountability. The high time-varying gamma activity of the material also precludes application of a number of techniques presently employed for light-water reactor fuel assay. The techniques selected for application in the refabrication facility are (1) active thermal neutron interrogation with fast-fission or delayed-neutron counting for fuel-rod and small-sample assay, (2) calorimetry for high-level waste assay, and (3) passive gamma scanning for low-level waste assay, and rapid on-line relative rod-loading measurements. The principal nondestructive assay subsystems are identified as (1) on-line devices for 100 percent product fuel rod assay and quality control, (2) a multipurpose device in the sample inspection laboratory for small- sample assay and secondary standards calibration, and (3) equipment for assay of high- and low-uranium content scrap and waste materials. A data processing system, which coordinates data from these subsystems with information from other process control sensors, is included to provide real-time material balance information. (U.S.)

  13. Measuring the safeguards value of material accountability

    International Nuclear Information System (INIS)

    Sicherman, A.

    1988-01-01

    Material accountability (MA) activities focus on providing after-the-fact indication of diversion or theft of special nuclear material (SNM). MA activities include maintaining records for tracking nuclear material and conducting periodic inventories and audits to ensure that loss has not occurred. This paper presents a value model concept for assessing the safeguards benefits of MA activities and for comparing these benefits to those provided by physical protection (PP) and material control (MC) components. The model considers various benefits of MA, which include: 1) providing information to assist in recovery of missing material, 2) providing assurance that physical protection and material control systems have been working, 3) defeating protracted theft attempts, and 4) properly resolving causes of and responding appropriately to anomalies of missing material and external alarms (e.g., hoax). Such a value model can aid decision-makers in allocating safeguards resources among PP, MC, and MA systems

    The presentation describes the evaluation of computerised system for processing of safeguards data and reporting to the IAEA in the Slovak Republic and in the Czech Republic in accordance with their Safeguards Agreements. The attention is given to the first code for processing of accounting data, established and operated in the Nuclear Research Institute in Rez in 1980. Further it is concentrated on the code ZARUKY, developed as a tool for control of and accounting for nuclear material at the State level in 1992, created on the database system CLIPPER-5 in operational system MS-DOS and operated until now. The general intention is to show and clarify main problems connected with the year 2000 and to share this experience with other colleagues. Possible ways for solution of these problems are listed and necessary regulatory role of the SSACs is presented. Also the main requirements for new code, which should communicate with the database of operators and reflect all limitations specified in their permissions, which should be a system with fully satisfactory safety, strictly defined confidentiality and should allow the access of several users in parallel is described. As a new component of this afford the requirements for reporting in accordance with the Protocol Additional to the Safeguard Agreement is mentioned. It is presented that the code in WINDOWS operation system on a database system ORACLE accepting also new date format 'YYYYMMDD' would meet all of these requirements. (author)

  19. The changing role of nuclear materials accounting

    International Nuclear Information System (INIS)

    Gibbs, P.W.

    1995-01-01

    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

    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 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

    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.

    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

  7. Material accountancy for metallic fuel pin casting

    1995-01-01

    The operation of the Fuel Conditioning Facility (FCF) is based on the electrometallurgical processing of spent metallic reactor fuel. The pin casting operation, although only one of several operations in FCF, was the first to be on-line. As such, it has served to demonstrate the material accountancy system in many of its facets. This paper details, for the operation of the pin casting process with depleted uranium, the interaction between the mass tracking system (MTG) and some of the ancillary computer codes which generate pertinent information for operations and material accountancy. It is necessary to distinguish between two types of material balance calculations -- closeout for operations and material accountancy for safeguards. The two have much in common, for example, the mass tracking system database and the calculation of an inventory difference, but, in general, are not congruent with regard to balance period and balance spatial domain. Moreover, the objective, assessment, and reporting requirements of the calculated inventory difference are very different in the two cases

    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

    The US Department of Energy (DOE) has clearly defined requirements for nuclear material control and accountability (MCA) of tritium whereas the International Atomic Energy Agency (IAEA) does not since tritium is not a fissile material. MCA requirements are expected for tritium fusion machines and will be dictated by the host country or regulatory body where the machine is operated. Material Balance Areas (MBA) are defined to aid in the tracking and reporting of nuclear material movements and inventories. Material sub-accounts (MSA) are established along with key measurement points (KMP) to further subdivide a MBA to localize and minimize uncertainties in the inventory difference (ID) calculations for tritium accountancy. Fusion systems try to minimize tritium inventory which may require continuous movement of material through the MSA. The ability of making meaningful measurements of these material transfers is described in terms of establishing the MSA structure to perform and reconcile ID calculations. For fusion machines, changes to the traditional ID equation will be discussed which includes breeding, burn-up, and retention of tritium in the fusion device. The concept of 'net' tritium quantities consumed or lost in fusion devices is described in terms of inventory taking strategies and how it is used to track the accumulation of tritium in components or fusion machines.

    Among the needs identified during initial surveys of nuclear facilities in Ukraine was improved accounting software for reporting material inventories to the regulatory body. AIMAS (Automated Inventory/Material Accounting System) is a PC-based application written in Microsoft Access that was jointly designed by an US/Ukraine development team. The design is highly flexible and configurable, and supports a wide range of computing infrastructure needs and facility requirements including situations where networks are not available or reliable. AIMAS has both English and Russian-language options for displays and reports, and it operates under Windows 3.1, 95, or NT 4.0trademark. AIMAS functions include basic physical inventory tracking, transaction histories, reporting, and system administration functions (system configuration, security, data backup and recovery). Security measures include multilevel password access control, all transactions logged with the user identification, and system administration control. Interfaces to external modules provide nuclear fuel burn-up adjustment and barcode scanning capabilities for physical inventory taking. AIMAS has been installed at Kiev Institute of Nuclear Research (KINR), South Ukraine Nuclear Power Plant (SUNPP), Kharkov Institute of Physics and Technology (KIPT), Sevastopol Institute of Nuclear Energy and Industry (SINEI), and the Ministry of Environmental Protection and Nuclear Safety/Nuclear Regulatory Administration (MEPNS/NRA). Facility specialists are being trained to use the application to track material movement and report to the national regulatory authority

    A study of applying the proposed near-real-time material accountancy model to the Tokai Reprocessing Plant, PNC (Power Reactor and Nuclear Fuel Development Corp.), showed that the model was feasible and effective to meet the IAEA (International Atomic Energy Agency) safeguards criteria in terms of detection timeliness and sensitivity. This study using the computer simulation technique is shown in this paper. In order to investigate the applicability of the model to the actual plant, the field test was carried out on the process in the material balance area (MBA) which covers the area from the input accountability vessel (IAV) to the product accountability vessel (PAV), in cooperation with JAERI. The key measuring points for dynamic physical inventory counts (D-PIT) are shown. The results of test evaluation are as follows: For timely detection, it will be able to evaluate an abnoumal accountancy in process by using the MUFd (material unaccounted for) obtained by the D-PIT about once every week. Therefore, this seems to satisfy the timely detection of IAEA safeguards criteria. As for detection, sensitivity and verification procedures, in order to clarify these criteria for a large scale reprocessing plant, further research and development will be required. In addition, since the field test was carried out along with normal plant operation, additional man-power problem was also considered. (Wakatsuki, Y.)

    The provision of the safeguards relevant reports and information in accordance with the comprehensive safeguards agreement (CSA) and the additional protocol (AP) is the basis for the IAEA safeguards. The government of Japan (Japan Safeguards Office, JSGO) has believed that the correct reports contribute to effective and efficient safeguards therefore the domestic quality assurance system for the reporting to the IAEA was already established at the time of the accession of the CSA in 1977. It consists of Code 10 interpretation (including the seminars for operators in Japan), SSAC's checks for syntax error, code and internal consistency (computer based consistency check between facilities) and the discussion with the IAEA on the facilities' measurement system for bulk-handling facilities, which contributes to the more accurate reports from operators. This spirit has been maintained for the entry into force of the AP. For example, questions and amplification from the IAEA will be taken into account the review of the AP declaration before sending to the IAEA and the open source information such as news article and scientific literature in Japanese is collected and translated into English, and the translated information is provided to the IAEA as the supplementary information, which may contribute to broadening the IAEA information source and to their comprehensive evaluation. The other safeguards relevant information, such as the mail-box information for SNRI at LEU fuel fabrication plants, is also checked by the JSGO's QC software before posting. The software was developed by JSGO and it checks data format, batch IDs, birth/death date, shipper/receiver information and material description code. This paper explains the history of the development of the Japanese quality assurance system regarding the reports and the safeguards relevant information to the IAEA. (author)

    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.

    In the framework of near-real-time accountancy for nuclear materials, safeguards statistical analysis based on the operator's data of a sequence of materials balance periods has been performed. Up to now, it is assumed that the operator's data are correct. A statistical model is presented that enables inspector verification measurements for a sequence of accounting periods to be included into a safeguards procedure. The analysis uses a two balance period and statistical concepts which are applied in the case of one accounting period. The interconnection of different safeguards measures shall be studied to get a basic idea about the procedure and it is shown that there might be fundamental differences to the one balance case

    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

    2003-01-01

    Presently, HB-Line work at the Savannah River Site consists primarily of the stabilization and packaging of nuclear materials for storage and the characterization of materials for disposition in H-Area. In order to ensure compliance with Material Control and Accountability (MC and A) Regulations, accountability measurements are performed throughout the HB-Line processes. Accountability measurements are used to keep track of the nuclear material inventory by constantly updating the amount of material in the MBAs (Material Balance Area) and sub-MBAs. This is done by subtracting the amount of accountable material that is added to a process and by adding the amount of accountable material that is put back in storage. A Physical Inventory is taken and compared to the ''Book Value'' listed in the Nuclear Material Accounting System. The difference (BPID) in the Book Inventory minus the Physical Inventory of a sub-account for bulk material must agree within the measurement errors combined in quadrature to provide assurance that nuclear material is accounted for. This work provides an overview of HB-Line processes and accountability measurements. The Scrap Recovery Line and Neptunium-237/Plutonium-239 Oxide Line are described and sampling and analyses for Phase II are provided. Recommendations for improvements are provided to improve efficiency and cost effectiveness

    This synopsis is intended to make a brief description about the way the Accountancy of Nuclear Material is carrying out in Mexican Facilities and in SSAC (State System of Accounting for and Control of Nuclear Material) nowadays involving computer languages and applications in use. The procedures were designed gradually over the past four years, address to accomplish finally the periods of time for sending ICR (Inventory Change Reports), PIL (Physical Inventory Listing), and MBR (Material Balance Period) reports to IAEA (International Atomic Energy Agency). The procedures starts in a certain facility where an inventory change and/or physical inventory taking has occurred. After that, the facility send information to the National Authority CNSNS (National Commission of Nuclear Safety and Safeguards) by means of a hard copy and magnetic file. The information included in the files is equal to that required by ICR, PIL, and MBR forms. This information is reviewed in Safeguards Section of CNSNS and if correct then the information is recorded in CNSNS data base using magnetic files. This involves a program in C++ to make a quickly and safe conversion from files in Excel application to the required ASCII (American Standard Code for Information Interchange) files. Once the information has been considered by CNSNS to be right, it is sent to IAEA. Thus CNSNS guarantee the information in facilities data base is exactly the same to that sent to IAEA. Working in this way timeliness has been improved, so that the number of delays in reports sent to IAEA has decreased. Internal procedures to review and make reports are followed by CNSNS Safeguards Section. (author)

    Neutron yields from 19 F(α,n) 22 Na reaction of uranium neutron interaction with uranium-bass materials, and the characteristics of shielded neutron assay probe have been studied. On the basis of the above examination, U-235 enrichment in UF 6 cylinders like model 30B and model 48Y was measured by the reaction and U-235 contents in the containers by non-destructive total passive neutron assay method. Total measurement efficiency as a result was found to be 6.44 x 10 -4 and 1.25 x 10 -4 for model 30B and model 40Y UF 6 cylinder, respectively. The uncertainty of measured enrichment as compared to Tag value obtained from chemical analysis approached about 5 % of relative error at 95 % confidence interval. In the follow-up action for the previously developed (1988) computer system of nuclear material accounting the error searching and treatment routine in accordance with code 10, of IAEA and respective facility attachment has been added to easing the burden of manual error correction by operator. In addition, the procedure for LEMUF calculation has been prepared to help bulk facility operators evaluating MUF in the period of material balance. (author)

    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

    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.

    Nasseri, K.K.

    1987-07-01

    Determination of the detection sensitivity of a materials accounting system to the loss of special nuclear material (SNM) requires (1) obtaining a relation for the variance of the materials balance by propagation of the instrument errors for the measured quantities that appear in the materials balance equation and (2) substituting measured values and their error standard deviations into this relation and calculating the variance of the materials balance. MAVARIC (Materials Accounting VARIance Calculations) is a custom spreadsheet, designed using the second release of Lotus 1-2-3, that significantly reduces the effort required to make the necessary variance (and covariance) calculations needed to determine the detection sensitivity of a materials accounting system. Predefined macros within the spreadsheet allow the user to carry out long, tedious procedures with only a few keystrokes. MAVARIC requires that the user enter the following data into one of four data tables, depending on the type of the term in the materials balance equation; the SNM concentration, the bulk mass (or solution volume), the measurement error standard deviations, and the number of measurements made during an accounting period. The user can also specify if there are correlations between transfer terms. Based on these data entries, MAVARIC can calculate the variance of the materials balance and the square root of this variance, from which the detection sensitivity of the accounting system can be determined

  10. Report of the Material Control and Material Accounting Task Force: the role of material control and material accounting in the safeguards program

    International Nuclear Information System (INIS)

    1978-03-01

    Results are presented of NRC Task Force investigations to identify the functions of a safeguards program in relation to the NRC safeguards objective, define the role and objectives of material control and material accounting systems within that program, develop goals for material control and material accounting based on those roles and objectives, assess current material control and material accounting requirements and performance levels in the light of the goals, and recommend future actions needed to attain the proposed goals. It was found that the major contribution of material accounting to the safeguards program is in support of the assurance function. It also can make secondary contributions to the prevention and response functions. In the important area of loss detection, a response measure, it is felt that limitations inherent in material accounting for some fuel cycle operations limit its ability to operate as a primary detection system to detect a five formula kilogram loss with high assurance (defined by the Task Force as a probability of detection of 90 percent or more) and that, in those cases, material accounting can act only in a backup role. Physical security and material control must make the primary contributions to the prevention and detection of theft, so that safeguards do not rely primarily for detection capabilities on material accounting. There are several areas of accounting that require more emphasis than is offered by the current regulatory base. These areas include: timely shipper-receiver difference analysis and reconciliation; a demand physical inventory capability; improved loss localization;discard measurement verification; timely recovery of scrap; improved measurement and record systems; and limits on cumulative inventory differences and shipper-receiver differences. An increased NRC capability for monitoring and analyzing licensee accounting data and more timely and detailed submittals of data to NRC by licensees are recommended

    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.

    1993-01-01

    As the Department of Energy (DOE) works to standardize the training for individuals performing materials control and accountability (MC and A) functions, the need for a definition of the appropriate training for MC and A auditors has become apparent. In order to meet the DOE requirement for individual training plans for all staff performing MC and A functions, the following set of guidelines was developed for consideration as applicable to MC and A auditors. The application of these guidelines to specific operating environments at individual DOE sites may require modification to some of the tables. The paper presents one method of developing individual training programs for an MC and A auditor or for an MC and A audit group based on the requirements for internal audits and assessments included in DOE Order 5633.3, Control and Accountability for Nuclear Materials

    The Russian/US Mining and Chemical Combine (Gorno-Kimichesky Kombinat, GKhK, also referred to as Krasnoyarsk-26) Material Protection, Control and Accounting (MPC and A) project was initiated in June 1996. A critical component of the ongoing cooperative MPC and A enhancements at the GKhK is the implementation of a computerized nuclear material control and accountability (MC and A) system. This system must meet the MC and A requirements of the GKhK by integrating the information generated by numerous existing and new MC and A components in place at the GKhK (e.g., scales, bar-code equipment, NDA measurement systems). During the first phase of this effort, the GKhK adapted CoreMAS (developed at Los Alamos National Laboratory) for use in the PuO 2 storage facility. This included formulation of Web-based user interfaces for plant personnel, Russification of the existing user interface, and at the functional level, modification of the CoreMAS stored procedures. The modified system is referred to as KrasMAS and builds upon completed work on CoreMAS. Ongoing efforts include adding GKhK specific report forms and expanding the functionality of the system for implementation at the radiochemical processing and reactor plants of the GKhK. Collaborations with other Russian facilities for appropriate parts of these efforts will be pursued

    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.

    KAERI(Korea Atomic Energy Research Institute) is constantly trying to efficiently implement safeguards in order to ensure international transparency and the credibility of KAERI safeguards. In its continuing efforts to implement safeguards efficiently, KAERI has developed KASIS(KAERI Safeguards Information Treatment System) and has linked KASIS with the RF ID system and HANARO fuel fabrication facility system. This paper describes the status of enhanced nuclear material accountancy through the development of KASIS at KAERI. The plans to more effectively implement nuclear material accountancy at KAERI are also reviewed

  7. Accounting Information Systems Implementation and Management Accounting Change

    Directory of Open Access Journals (Sweden)

    Bredmar Krister

    2014-09-01

    Full Text Available Background: There is an on-going discussion within management accounting research regarding how to work with performance measures. In the process of developing new forms of performance measurement the task of choosing business metrics is central. This process is closely connected to the implementation of IT solutions. Objectives: In order to understand how new performance measurement solutions are implemented and used, it becomes crucial to understand how measures are selected and how new accounting information systems (AIS are developed and implemented. Methods/approach: The paper builds on the case of an on-going AIS project at a large, public university in Sweden. The empirical material was collected using a semi-action research approach over a two-year period. The majority of the material comes from written documentation and minutes. Results: Even though the implementation of a new AIS triggers a change in the management accounting practice, this study shows that this is done in more than one perspective. Conclusions: As the project develops, new priorities and objectives evolve, which in the end shape what management accounting change becomes.

  8. Structure and experience of the state system of accounting for and control of nuclear material (SSAC) in the German Democratic Republic

    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

    The Safeguards Accountability Network (SAN) is an online computer system that was developed by Rockwell International to track the accounting and processing of nuclear materials from the time it arrives at Rocky Flats Plant through its life cycle. A major contributor to the success of SAN is the use of audit trails. They have proven to be invaluable for the management and safeguarding of these sensitive materials at Rocky Flats. Producing effective audit trails requires the recording of all pertinent transactions and the capability to access and report the information in a timely fashion. This paper discusses the implementation and application of these audit trails on the Rocky Flats SAN system

    Opelka, J.H.; Sutton, W.B.

    1982-01-01

    The validity of the alarm threshold 4sigma has been checked for hypothetical large and small facilities using a two-stage decision model in which the diverter's strategic variable is the quantity diverted, and the defender's strategic variables are the alarm threshold and the effectiveness of the physical security and material control systems in the possible presence of a diverter. For large facilities, the material accounting system inherently appears not to be a particularly useful system for the deterrence of diversions, and essentially no improvement can be made by lowering the alarm threshold below 4sigma. For small facilities, reduction of the threshold to 2sigma or 3sigma is a cost effective change for the accounting system, but is probably less cost effective than making improvements in the material control and physical security systems

    1988-09-28

    Nuclear safeguards applied by the International Atomic Energy Agency (IAEA) are one element of the non-proliferation regime'', the collection of measures whose aim is to forestall the spread of nuclear weapons to countries that do not already possess them. Safeguards verifications provide evidence that nuclear materials in peaceful use for nuclear-power production are properly accounted for. Though carried out in cooperation with nuclear facility operators, the verifications can provide assurance because they are designed with the capability to detect diversion, should it occur. Traditional safeguards verification measures conducted by inspectors of the IAEA include book auditing; counting and identifying containers of nuclear material; measuring nuclear material; photographic and video surveillance; and sealing. Novel approaches to achieve greater efficiency and effectiveness in safeguards verifications are under investigation as the number and complexity of nuclear facilities grow. These include the zone approach, which entails carrying out verifications for groups of facilities collectively, and randomization approach, which entails carrying out entire inspection visits some fraction of the time on a random basis. Both approaches show promise in particular situations, but, like traditional measures, must be tested to ensure their practical utility. These approaches are covered on this report. 15 refs., 16 figs., 3 tabs.

  16. Financial Accountant Versus Managerial Accountant in the Hotel Business System

    Directory of Open Access Journals (Sweden)

    Ivana Zubac

    2012-01-01

    Full Text Available From the perspective of financial or managerial accountant, subject of interest in this paper is the relationship of financial and managerial accounting in the hotel business. Being necessary functions within the business system of hotel company, their mutual connection as well as their differences are explained. The management of hotel company makes decisions based on accounting information from both parts of accounting. As support to hotel management in decision-making, financial accountant provides financial information about past events, while managerial accountant provides non-financial information oriented toward future. The example above is just one out of many specific tasks, which are performed by accountants of specific part of hotel accounting system. Without their support, the management could not make correct and timely decisions with certainty. The importance of the roles of financial and managerial accountant is reflected through need for a wide knowledge in the field of accounting in specific business conditions of hotel industry.

    Full Text Available Management accounting was established as a new direction in accounting from the 50-ies of the XX century. However, it is still debatable as to its nature, content and the place it occupies in the accounting system. The reason for this is that different authors interpreting different way of the term "management accounting". Namely the connection accounting - management creates differences in interpretation. A significant part of the authors emphasize the concept of accounting, others focus on management and the third part of it as a autonomous system. In this article we aim to establish a relationship of management accounting with other types of accountings and his place in the system of accounting.

    RRP has a 800t·Upr capacity a year to re-process, where would be handled a large amount of nuclear materials as solution. A large scale plant like RRP will require accurate materials accountancy system, so that the vessel calibration with high-precision is very important as initial vessel calibration before operation. In order to obtain the calibration curve, it is needed well-known each the increment volume related with liquid height. Then we performed at least 2 or 3 times run with water for vessel calibration and careful evaluation for the calibration data should be needed. We performed vessel calibration overall 210 vessels, and the calibration of 81 vessels including IAT and OAT were held under presence of JSGO and IAEA inspectors taking into account importance on the material accountancy. This paper describes outline of the initial vessel calibration and calibration results based on back pressure measurement with dip tubes. (author)

  1. Some ideas for next-generation controlled nuclear materials accountability techniques

    International Nuclear Information System (INIS)

    Brough, W.; Parrish, C.

    1994-08-01

    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

  2. The role of certified reference materials in material control and accounting

    International Nuclear Information System (INIS)

    Turel, S.P.

    1979-01-01

    One way of providing an adequate material control and accounting system for the nuclear fuel cycle is to calculate material unaccounted for (MUF) after a physical inventory and to compare the limit of error of the MUF value (LEMUF) against prescribed criteria. To achieve a meaningful LEMUF, a programme for the continuing determination of systematic and random errors is necessary. Within this programme it is necessary to achieve traceability of all Special Nuclear Material (SNM) control and accounting measurements to an International/National Measurement System by means of Certified Reference Materials. SNM measurements for control and accounting are made internationally on a great variety of materials using many diverse measurement procedures by a large number of facilities. To achieve valid overall accountability over this great variety of measurements there must be some means of relating all these measurements and their uncertainties to each other. This is best achieved by an International/National Measurement System (IMS/NMS). To this end, all individual measurement systems must be compatible to the IMS/NMS and all measurement results must be traceable to appropriate international/national Primary Certified Reference Materials. To obtain this necessary compatibility for any given SNM measurement system, secondary certified reference materials or working reference materials are needed for every class of SNM and each type of measurement system. Ways to achieve ''traceability'' and the various types of certified reference material are defined and discussed in this paper. (author)

  3. Material Control and Accountability Experience at the Fuel Conditioning Facility

    International Nuclear Information System (INIS)

    Vaden, D.; Fredrickson, G.L.

    2007-01-01

    The Fuel Conditioning Facility (FCF) at the Idaho National Laboratory (INL) treats spent nuclear fuel using an electrometallurgical process that separates the uranium from the fission products, sodium thermal bond, and cladding materials. Material accountancy is necessary at FCF for two reasons: 1) it provides a mechanism for detecting a potential loss of nuclear material for safeguards and security, and 2) it provides a periodic check of inventories to ensure that processes and materials are within control limits. Material Control and Accountability is also a Department of Energy (DOE) requirement (DOE Order 474.1). The FCF employs a computer based Mass Tracking (MTG) System to collect, store, retrieve, and process data on all operations that directly affect the flow of materials through the FCF. The MTG System is important for the operations of the FCF because it supports activities such as material control and accountability, criticality safety, and process modeling. To conduct material control and accountability checks and to monitor process performance, mass balances are routinely performed around the process equipment. The equipment used in FCF for pyro-processing consists of two mechanical choppers and two electro-refiners (the Mark-IV with the accompanying element chopper and Mark-V with the accompanying blanket chopper for processing driver fuel and blanket, respectively), and a cathode processor (used for processing both driver fuel and blanket) and casting furnace (mostly used for processing driver fuel). Performing mass balances requires the measurement of the masses and compositions of several process streams and equipment inventories. The masses of process streams are obtained via in-cell balances (i.e., load cells) that weigh containers entering and leaving the process equipment. Samples taken at key locations are analyzed to determine the composition of process streams and equipment inventories. In cases where equipment or containers cannot be

  8. The application of statistical techniques to nuclear materials accountancy

    International Nuclear Information System (INIS)

    Annibal, P.S.; Roberts, P.D.

    1990-02-01

    Over the past decade much theoretical research has been carried out on the development of statistical methods for nuclear materials accountancy. In practice plant operation may differ substantially from the idealized models often cited. This paper demonstrates the importance of taking account of plant operation in applying the statistical techniques, to improve the accuracy of the estimates and the knowledge of the errors. The benefits are quantified either by theoretical calculation or by simulation. Two different aspects are considered; firstly, the use of redundant measurements to reduce the error on the estimate of the mass of heavy metal in an accountancy tank is investigated. Secondly, a means of improving the knowledge of the 'Material Unaccounted For' (the difference between the inventory calculated from input/output data, and the measured inventory), using information about the plant measurement system, is developed and compared with existing general techniques.

    This paper reports that the Department of Energy Order (DOE) 5633.3, Control and Accountability for Nuclear Materials, includes several requirements for development and implementation of an internal audit program. Martin Marietta Energy System, Inc., manages five sites in Tennessee, Kentucky, and Ohio for the DOE Field Office, Oak Ridge and has a Central Nuclear Materials Control and Accountability (NMC and A) Manager with matrixed responsibility for the NMC and A program at the five sites. The Energy Systems Central NMC and A Manager has developed an NMC and A Internal Audit Handbook which defines the functional responsibilities, performance criteria, and reporting and documentation requirements for the Energy Systems NMC and A Internal Audit Program. The initial work to develop and implement these standards was tested at the K-25 Site when the site hired an internal auditor to meet the DOE requirements for an NMC and A Internal Audit program

    Naruki, Kaoru; Aoki, Minoru; Mizuno, Ohichi; Mishima, Tsuyoshi

    1979-01-01

    More than 30 tons of plutonium-uranium mixed-oxide fuel have been manufactured at the Plutonium Facility in PNC for JOYO, FUGEN and DCA (Deuterium Critical Assembly) and for the purpose of irradiation tests. This report reviews the nuclear material accountability control system adopted in the Plutonium Facility. Initially, the main objective of the system was the criticality control of fissible materials at various stages of fuel manufacturing. The first part of this report describes the functions and the structure of the control system. A flow chart is provided to show the various stages of material flow and their associated computer files. The system is composed of the following three sub-systems: procedures of nuclear material transfer; PIT (Physical Inventory Taking); data retrieval, report preparation and file maintenance. OMR (Optical Mark Reader) sheets are used to record the nuclear material transfer. The MUF (Materials Unaccounted For) are evaluated by PIT every three months through computer processing based on the OMR sheets. The MUF ratio of Pu handled in the facility every year from 1966 to 1977 are presented by a curve, indicating that the MUF ratio was kept well under 0.5% for every project (JOYO, FUGEN, and DCA). As for the Pu safeguards, the MBA (Material Balance Area) and the KMP (Key Measurement Point) in the facility of PNC are illustrated. The general idea of the projected PINC (Plutonium Inventory Control) system in PNC is also shortly explained. (Aoki, K.)

  11. Near-real-time material accountancy - A technical status report

    International Nuclear Information System (INIS)

    Lovett, J.; Ikawa, K.; Sellinschegg, D.; Shipley, J.

    1983-01-01

    Near-Real-time materials accountancy as applied to reprocessing plants involves two major elements, measurement of the in-process physical inventory at frequent intervals, and statistical evaluation of the resulting sequential material balance data. For most reprocessing plants the bulk of the in-process inventory is in measurable intermediate ''buffer'' tanks. The plutonium inventory in the solvent extraction system, which does not appear to be directly measureable, could cause a reduction in sensitivity of the sequential data analysis. Studies are in progress, and it is hoped that an acceptable means for accounting for these variations can be found. Consultants at a meeting in January 1982 agreed that statistical tests for evaluating sequential material balance data will increase both detection timeliness and detection sensitivity. IAEA verification of operator-generated measurement data is an area requiring significantly increased effort, but here too studies are in progress which should help to reduce inspection effort in increased effectiveness

    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

  13. 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

  15. State and regional systems of accounting for and control of nuclear materials cooperation between international, regional and states safeguards organizations: An evolving issue

    International Nuclear Information System (INIS)

    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)

    Effective materials accounting for special nuclear material in modern fuel cycle facilities will depend heavily on sophisticated data analysis techniques. Decision analysis, which combines elements of estimation theory, decision theory, and systems analysis, is a framework well suited to the development and application of these techniques. Augmented by pattern-recognition tools such as the alarm-sequence chart, decision analysis can be used to reduce errors caused by subjective data evaluation and to condense large collections of data to a smaller set of more descriptive statistics. Application to data from a model plutonium nitrate-to-oxide conversion process illustrates the concepts

    Material control and accounting (MC and A) of special nuclear material (SNM) must supplement physical security to protect SNM from unlawful use such as terrorist activities. This article reviews MC and A safeguards of SNM in the United States. The following topics are covered: a brief perspective and history of MC and A safeguards, current MC and A practices, measurement methods for SNM, historical MC and A performance, a description of near-real-time MC and A systems, and conclusions on the status of MC and A in the United States

    Lawrence Livermore National Laboratory (LLNL) undertook the task of analyzing the actual and potential value of an interfacility NRC material accounting system in deterring and detecting both material diversion and facility material accounting data falsification. The most important conclusion is that only relatively minor changes are needed to upgrade the current NRC interfacility reporting system. The emphasis of the task was on evaluating the usefulness of an NRC-monitored material accounting information system in providing protection against accounting fraud at the plant management or corporate level. The Nuclear Materials Management and Safeguards System (NMMSS) and the NRC Safeguards Status Report System (SSRS), the principal constituents of the current interfacility NRC material accounting information system, are described. Their relationship is shown in two information flow diagrams. Deterministic accounting checks and balances are discussed, both for the current NRC interfacility material accounting system and for an upgraded system. Detection mechanisms are described that would use currently available data and that could be exercised by the NRC in its safeguards management role. Additional checks and balances are recommended, with corresponding changes in data reporting requirements, to upgrade NRC interfacility material accounting system

  20. Human performance: An essential element in materials control and accountability

    1996-01-01

    The importance of the role of human performance in the successful and effective operation of many activities throughout many industries has been well documented. Most closely related to the materials control and accountability area is the work in human factors that has been ongoing in the U.S. nuclear industry since the Three Mile Island Nuclear Power Plant accident in 1979. Research related to the role of human reliability, human-system interface, and organization and management influences has been and is still being conducted to identify ways to enhance the safe and effective operation of nuclear facilities. This paper will discuss these human performance areas and how they relate to the materials control and accountability area. Particular attention will be focussed on the notion of open-quotes safety cultureclose quotes and how it can be defined and measured for understanding the values and attitudes held by individuals working in the materials control area. It is widely believed that the culture of an organization, which reflects the expectations and values of the management of an organization, is a key element to the operation of that organization. The human performance element is one which has not received a great deal of consideration in the materials control and accountability area and yet it will be demonstrated that it is an essential component to ensure the success of safeguards activities

  1. Statistical analysis and Kalman filtering applied to nuclear materials accountancy

    Much theoretical research has been carried out on the development of statistical methods for nuclear material accountancy. In practice, physical, financial and time constraints mean that the techniques must be adapted to give an optimal performance in plant conditions. This thesis aims to bridge the gap between theory and practice, to show the benefits to be gained from a knowledge of the facility operation. Four different aspects are considered; firstly, the use of redundant measurements to reduce the error on the estimate of the mass of heavy metal in an 'accountancy tank' is investigated. Secondly, an analysis of the calibration data for the same tank is presented, establishing bounds for the error and suggesting a means of reducing them. Thirdly, a plant-specific method of producing an optimal statistic from the input, output and inventory data, to help decide between 'material loss' and 'no loss' hypotheses, is developed and compared with existing general techniques. Finally, an application of the Kalman Filter to materials accountancy is developed, to demonstrate the advantages of state-estimation techniques. The results of the analyses and comparisons illustrate the importance of taking into account a complete and accurate knowledge of the plant operation, measurement system, and calibration methods, to derive meaningful results from statistical tests on materials accountancy data, and to give a better understanding of critical random and systematic error sources. The analyses were carried out on the head-end of the Fast Reactor Reprocessing Plant, where fuel from the prototype fast reactor is cut up and dissolved. However, the techniques described are general in their application. (author)

    Markin, J.T.; Augustson, R.H.; Eccleston, G.W.; Hakkila, E.A.

    1991-01-01

    This paper reports that nuclear materials accountancy was introduced as a primary safeguards measure in international safeguards at the inception of the EURATOM safeguards directorate in 1959 and in IAEA safeguards in 1961 with the issuance of INFCIRC 26. As measurement technology evolved and safeguarded facilities increased in both number and size, measurement methodology requirements increased as reflected in INFCIRC 66 (Rev 2.) in 1968 and later in INFCIRC 153 in 1972. Early measurements relied heavily on chemical analysis, but in the 1960s the measurements evolved more and more toward nondestructive assay. Future nuclear materials accountancy systems will increase in complexity, driven by larger and more complex facilities; more stringent health, safety, and environmental considerations; and unattended automation in facility operations

    BNFL is currently designing and installing a fully automated system of data capture, storage and processing for its Thermal Oxide Reprocessing Plant (THORP) at Sellafield. A prototype Near Real Time Materials Accountancy (NRTMA) system has been used to demonstrate the advantages of this method of materials control to the future plant operators and their feedback continues to be incorporated in the development of user interfaces. NRTMA has been included in the User Requirements Specification for Chemical Plant Information Computer, the top-tier computer which is being provided to archive, retrieve and analyse plant data. The paper describes a development programme of performance and quality related improvements to the prototype NRTMA system. Furthermore, advanced diagnostic systems are described which will help the operator in the resolution of anomalies

  4. Efficiency of material accountability verification procedures: A case study

    International Nuclear Information System (INIS)

    Avenhaus, R.

    1976-01-01

    In the model agreement INFCIRC/153 the international nuclear materials safeguards system has been established such that the material accountability principle is the main safeguards tool, with containment and surveillance as complementary measures. In addition, it has been agreed that the plant operator generates all data necessary for the material balance establishment and reports them to the safeguards authority and furthermore, that these data are verified by representatives of the safeguards authority with the help of independent measurements. In this paper, the problem of the determination of the efficiency of the combined system - data verification and material balance establishment - is analysed. Here, the difficulty arises that the two statistical procedures used are not independent because part of the operator's data are used in both cases. It is the purpose of this paper to work out the procedure for calculating the systems efficiency, i.e. the overall guaranteed probability of detection for the whole system for an assumed diversion and a given false alarm rate as a function of the safeguards effort spent over a given interval of time. Simplified formulae are derived which allow for a quick determination of the whole system efficiency: it is shown that the correlation between the two parts of the total system can be neglected. Therefore, the total systems efficiency can be represented as the product of the efficiencies of the two subsystems. The method developed is applied to a concrete case of a chemical reprocessing plant for irradiated fuels on the basis of data collected earlier. (author)

  7. Material control and accounting requirements for uranium enrichment facilities

    International Nuclear Information System (INIS)

    Ting, P.

    1991-01-01

    This paper reports that the U.S. Nuclear Regulatory Commission has defined material control and accounting (MC and A) requirement for low-enriched uranium enrichment plants licensed under 10 CFR parts 40 and 70. Following detailed assessment of potential safeguards issues relevant to these facilities, a new MC and A rule was developed. The primary safeguards considerations are detection of the loss of special nuclear material, detection of clandestine production of special nuclear material of low strategic significance for unauthorized use or distribution, and detection of unauthorized production of uranium enriched to ≥10 wt % U-235. The primary safeguards concerns identified were the large absolute limit of error associated with the material balance closing, the inability to shutdown some uranium enrichment technologies to perform a cleanout inventory of the process system, and the flexibility of some of these technologies to produce higher enrichments. Unauthorized production scenarios were identified for some technologies that could circumvent the detection of the production and removal of 5 kilograms of U-235 as high-enriched uranium through conventional material control and accounting programs. Safeguards techniques, including the use of production and process control information, measurements, and technical surveillance, were identified to compensate for these concerns

    The internal audit program of the Nuclear Material Control and Accountability (NMCandA) Department at the Oak Ridge Y-12 Plant, through inventory-verification audits, inventory-observation audits, procedures audits, and records audits, evaluates the adequacy of material accounting and control systems and procedures throughout the Plant; appraises and verifies the accuracy and reliability of accountability records and reports; assures the consistent application of generally accepted accounting principles in accounting for nuclear materials; and assures compliance with the Department of Energy (DOE) and NMCandA procedures and requirements. The internal audit program has significantly strengthened the control and accountability of nuclear materials through improving the system of internal control over nuclear materials, increasing the awareness of materials control and accountability concerns within the Plant's material balance areas (MBAs), strengthening the existence of audit trails within the overall accounting system for nuclear materials, improving the accuracy and timeliness of data submitted to the nuclear materials accountability system, auditing the NMCandA accounting system to ensure its accuracy and reliability, and ensuring that all components of that system (general ledgers, subsidiary ledgers, inventory listings, etc.) are in agreement among themselves

  9. Comparison of materials accounting in conversion and coconversion processes

    1981-01-01

    Materials accounting systems performances are compared for plutonium nitrate-to-oxide conversion [Oxalate (III)] and uranium-plutonium coconversion (Coprecal and modified Coprecal). These processes have the same design basis plutonium throughput and achieve this throughput in parallel operating lines. However, the process line configurations differ. In comparing the materials loss detection sensitivities for the three processes, we find better materials loss detection sensitivity for the Oxalate (III) process than for either of the two Coprecal processes, better single-balance detection sensitivity for the original Coprecal than for the modified Coprecal, and better long-term detection sensitivity (> 1d) for the modified Coprecal than for the original Coprecal. Sensivity differences result from differences in in-process inventories, feeding arrangements, and scrap generation

    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

    1978-03-01

    A special review was made of the safeguards maintained by licensees possessing 5 kg or more of strategic special nuclear material (SSNM), i.e., plutonium, uranium-233, or uranium enriched in the uranium-235 isotope to 20 percent or more. A Task Force was formed to define the roles and objectives of material control and material accounting in the NRC safeguards program; recommend goals for material control and material accounting systems based on their roles and objectives; assess the extent to which the existing regulatory base meets or provides the capability to meet the recommended goals; and to provide direction for material control and material accounting development, including both near-term and long-term upgrades. Based on results of Task Force investigations it is recommended that licensee plans for measurement control programs be submitted in response to Section 70.57(c) of Title 10 of the Code of Federal Regulations. Other recommendations include the review and upgrading, as necessary, of measurement error propagation models used by each licensee; revision of Nuclear Materials Management and Safeguards System (NMMSS) reporting entities for SSNM licensees to be consistent with the partitioning of facilities into plants or, if appropriate, accounting units; review of NMMSS reporting entities for SSNM licensees to assure that data for high enriched uranium operations are clearly separated from low enriched uranium operations; upgrading of the editing by NMMSS of reported licensee safeguards data for accuracy and consistency; and the acquisition of (a) a secure interactive computer capability for use in collecting, storing, sorting, and analyzing special nuclear material accounting data, and (b) associated flexible computer software that presents safeguards information in a succinct and comprehensive manner

    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

    Zardecki, A.

    1994-01-01

    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

    1978-03-01

    A blueprint is presented for the development of improved material control and material accounting systems by integrating the goals and capabilities of material control and material accounting and recommending specific upgrading actions. An analysis is included of several specific issues and developing recommendations for future actions related to those issues. It is felt that there is a need for a program to define specific quantified goals for an integrated safeguards program, and to monitor safeguards programs in terms of these goals. NRC should give highest priority to developing regulations and guides that will enable material control to make a greater contribution to safeguards by providing greater timeliness and sensitivity in detecting and assessing material losses. It is recommended that a technical study be conducted to determine a quantitative measure or at least a figure of merit for the effectiveness of a security clearance program, based upon full field background investigations, in protecting against malevolent conspiracies involving two or more security cleared individuals. It is also recommended that a specific effort be initiated to formulate an approach to combating collusion. This effort should specifically consider the contribution that material control and material accounting programs can make to safeguards effectiveness in this area

    The All-Russian Scientific Research Institute of Experimental Physics (VNIIEF), founded in 1946 at the historic village of Sarov, in Nizhniy Novgorod Oblast, is the largest nuclear research center in the Rosatom complex. In the framework of international collaboration, the United States (US) Department of Energy/National Nuclear Security Agency, in cooperation with US national laboratories, on the one hand, Rosatom and VNIIEF on the other hand, have focused their cooperative efforts to upgrade the existing material protection control and accountability system to prevent unauthorized access to the nuclear material. In this paper we will discuss the present status of material control and accounting (MC and A) system upgrades and the preliminary results from a pilot program on the MC and A system performance testing that was recently conducted at one technical area.

    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.

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

    2010-10-01

    An accurate volume measurement system for plutonium nitrate solution stored in an accountability tank with dip-tubes has been developed and demonstrated over fifteen years at the Plutonium Conversion Development Facility of the Japan Atomic Energy Agency. As a result of calibrations during the demonstration, it was proved that measurement uncertainty practically achieved and maintained was less than 0.1% (systematic character) and 0.15% (random) as one sigma which was half of the current target uncertainty admitted internationally. It was also proved that discrepancy between measured density and analytically determined density was less than 0.002 g·cm -3 as one sigma. These uncertainties include effects by long term use of the accountability tank where cumulative plutonium throughput is six tons. The system consists of high precision differential pressure transducers and a dead-weight tester, sequentially controlled valves for periodical zero adjustment, dampers to reduce pressure oscillation and a procedure to correct measurement biases. The sequence was also useful to carry out maintenances safely without contamination. Longevity of the transducer was longer than 15 years. Principles and essentials to determine solution volume and weight of plutonium, measurement biases and corrections, accurate pressure measurement system, maintenances and diagnostics, operational experiences, evaluation of measurement uncertainty are described.

    The UKAEA have operated systems of nuclear materials accountancy in research and development establishments handling large quantities of material for over 20 years. In the course of that time changing requirements for nuclear materials control and increasing quantities of materials have required that accountancy systems be modified and altered to improve either the fundamental system or manpower utilization. The same accountancy principles are applied throughout the Authority but procedures at the different establishments vary according to the nature of their specific requirements; there is much in the cumulative experience of the UKAEA which could prove of value to other organizations concerned with nuclear materials accountancy or safeguards. This paper reviews the present accountancy system in the UKAEA and summarizes its advantages. Details are given of specific experience and solutions which have been found to overcome difficulties or to strengthen previous weak points. Areas discussed include the use of measurements, the establishment of measurement points (which is relevant to the designation of MBAs), the importance of regular physical stock-taking, and the benefits stemming from the existence of a separate accountancy section independent of operational management at large establishments. Some experience of a dual system of accountancy and criticality control is reported, and the present status of computerization of nuclear material accounts is summarized. Important aspects of the relationship between management systems of accountancy and safeguards' requirements are discussed briefly. (author)

    The measurement techniques for Pu samples and spent fuel assembly were developed in support of the implementation of national inspection responsibility under the Atomic Energy Act promulgated in 1994 and a computer program was also developed to assess the total nuclear material balance by facility declared records. The results of plutonium isotopic determination by gamma-ray spectrometry with high resolution germanium detector with peak analysis codes (FRAM and MGA codes) were approached to within 1% {approx} 2% of error from chemical analysis values by mass spectrometry. A gamma-ray measurement system for underwater spent nuclear fuels was developed and tested successfully. The falsification of facility and state records can be traced with the help of the developed computer code against declared reports submitted by the concerned state. This activity eventually resulted in finding the discrepancy of accountability records. 18 figs, 20 tabs, 27 refs. (Author).

    The ICPP high enriched uranium recovery process has historically been operated as a single Material Balance Area (MBA), with input and output measurement capabilities. Safeguards initiated changes in the last five years have resulted in significant materials control and accountability improvements. Those changes include semi-automation of process accountability measurement, data collection and recording; definition of Sub-MBAs; standard plant cleanouts; and, bimonthly inventory estimates. Process monitoring capabilities are also being installed to provide independent operational procedural compliance verification, process anomaly detection, and enhanced materials traceability. Development of a sensitivity analysis approach to defining process measurement requirements is in progress

    Analytical techniques are widely used for verification and accountancy of nuclear materials. Nuclear Material (NM) inventories are based on sampling followed by Destructive Analysis. Destructive Analyses range from traditional chemical techniques to recent implementations of radiometric methods. These techniques are performed to quantify the amount of nuclear material (elemental assay and isotopic composition) present in a specific item, container, or in some cases facility and resolving shipper-receiver differences. Analytical techniques used for the MC and A of nuclear material normally require more attention than that for process control because the largest contribution to Material Unaccounted For is in measurement uncertainty. Therefore analytical techniques selected for material control and accountability are highly precise and they comply with accepted 'International Target Values 2010'. (author)

    1996-01-01

    The Fuel Conditioning Facility (FCF) treats spent nuclear fuel using an electrometallurgical process that separates the uranium from the fission products, sodium thermal bond and cladding materials. Material accountancy is necessary at FCF for two reasons: first, it provides a mechanism for detecting a potential loss of nuclear material for safeguards and security; second, it provides a periodic check of inventories to ensure that processes and material are under control. By weighing material entering and leaving a process, and using sampling results to determine composition, an inventory difference (ID) results when the measured inventory is compared to the predicted inventory. The ID and its uncertainty, based on error propagation, determines the degree of assurance that an operation proceeded according to expectations. FCF uses the ID calculation in two ways: closeout, which is the ID and uncertainty for a particular operational step, and material accountancy, which determines an ID and its associated uncertainty for a material balance area through several operational steps. Material accountancy over the whole facility for a specified time period assists in detecting diversion of nuclear material. Data from depleted uranium operations are presented to illustrate the method used in FCF

    Full text: Near Real Time Materials Accountancy (NRTMA) is the leading edge technical solution employed by BNFL for in-process verification and timely detection of anomalies. It facilitates Safeguards inspection without intrusion and safeguards interim assurance without a monthly plant shut down. BNFL has been committed to the development of NRTMA for commercial plutonium plants. This multimedia poster presentation describes the features of Thorp and SMP relevant to the application of NRTMA, and then the statistical engine of NRTMA, which has many features in common across the two systems. This final point renders BNFL's implementation of NRTMA eligible for application to other nuclear and non-nuclear installations. NRTMA is operational in the Thermal Oxide Reprocessing Plant (Thorp). NRTMA supports fulfilment of the monthly timeliness component of the safeguards approach so that Thorp can remain operational between annual Physical Inventory Takings (PITs). The In-Process Inventory (IPI) is determined by for each vessel, or group of vessels, based on determination of weight and assay (or volume and concentration) or process models. Data trending enhances the quality of important sources of data. Plant status rules are used to determine times when it is appropriate to determine the IPI. The number of IPIs is currently some tens per annual campaign (PIT to PIT), although the NRTMA System can accommodate more. NRTMA is an intrinsic element in the safeguards and nuclear materials control and accountancy arrangements for the Sellafield MOX Plant (SMP). This fulfils the timeliness component of the safeguards approach and does not require monthly clean out or run down for verification. The SMP is a batch process. In a plant location, there is a 'Window of Opportunity' for determining that component of the inventory while it is stationary. The IPI can be determined when the 'Windows of Opportunity' for the entire Works Accountancy Area align. There are potentially many

    2002-01-01

    The ReflectoActive(trademark) Seals system, a continuously monitored fiber optic, active seal technology, provides real-time tamper indication for large arrays of storage containers. The system includes a PC running the RFAS software, an Immediate Detection Unit (IDU), an Optical Time Domain Reflectometer (OTDR), links of fiber optic cable, and the methods and devices used to attach the fiber optic cable to the containers. When a breach on any of the attached fiber optic cable loops occurs, the IDU immediately signals the connected computer to control the operations of an OTDR to seek the breach location. The ReflectoActive(trademark) Seals System can be adapted for various types of container closure designs and implemented in almost any container configuration. This automatic protection of valued assets can significantly decrease the time and money required for surveillance. The RFAS software is the multi-threaded, client-server application that monitors and controls the components of the system. The software administers the security measures such as a two-person rule as well as continuous event logging. Additionally the software's architecture provides a secure method by which local or remote clients monitor the system and perform administrative tasks. These features provide the user with a robust system to meet today's material control and accountability needs. A brief overview of the hardware, and different hardware configurations will be given. The architecture of the system software, and its benefits will then be discussed. Finally, the features to be implemented in future versions of the system will be presented

    A description is presented of a Material Control System Simulator (MCSS) program for determination of material accounting uncertainty and system response to particular adversary action sequences that constitute plausible material diversion attempts. The program is intended for use in situations where randomness, uncertainty, or interaction of adversary actions and material control system components make it difficult to assess safeguards effectiveness against particular material diversion attempts. Although MCSS may be used independently in the design or analysis of material handling and processing systems, it has been tailored toward the determination of material accountability and the response of material control systems to adversary action sequences.

    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)

    1996-01-01

    The hospital materials management function--ensuring that goods and services get from a source to an end user--encompasses many areas of the hospital and can significantly affect hospital costs. Performing this function in a manner that will keep costs down and ensure adequate cash flow requires effective management of a large amount of information from a variety of sources. To effectively coordinate such information, most hospitals have implemented some form of materials management information system (MMIS). These systems can be used to automate or facilitate functions such as purchasing, accounting, inventory management, and patient supply charges. In this study, we evaluated seven MMISs from seven vendors, focusing on the functional capabilities of each system and the quality of the service and support provided by the vendor. This Evaluation is intended to (1) assist hospitals purchasing an MMIS by educating materials managers about the capabilities, benefits, and limitations of MMISs and (2) educate clinical engineers and information system managers about the scope of materials management within a healthcare facility. Because software products cannot be evaluated in the same manner as most devices typically included in Health Devices Evaluations, our standard Evaluation protocol was not applicable for this technology. Instead, we based our ratings on our observations (e.g., during site visits), interviews we conducted with current users of each system, and information provided by the vendor (e.g., in response to a request for information [RFI]). We divided the Evaluation into the following sections: Section 1. Responsibilities and Information Requirements of Materials Management: Provides an overview of typical materials management functions and describes the capabilities, benefits, and limitations of MMISs. Also includes the supplementary article, "Inventory Cost and Reimbursement Issues" and the glossary, "Materials Management Terminology." Section 2. The

    1999-01-01

    To date, the Department of Energy's (DOE) Material Protection, Control, and Accountancy (MPC and A) program has assisted in the implementation of operational site-wide MPC and A systems at several nuclear facilities in Russia. Eleven sites from the civilian sector have completed the site-wide installations and two have completed sub-site installations. By the end of 1999, several additional sites will have completed site-wide and sub-site system installations through DOE assistance. the effort at the completed sites has focused primarily on the design, integration, and installation of upgraded MPC and A systems. In most cases, little work has been performed to ensure that the installed systems will be sustained. Because of concerns that the installed systems would not be operated in the future, DOE established a sustainability pilot program involving the 11 sites. The purpose of DOE's MPC and A Sustainability Program is to ensure that MPC and A upgrades installed at sites in Russia are effective and will continue to operate over the long term. The program mission is to work with sites where rapid upgrades have been completed to cultivate enduring and consistent MPC and A practices. The program attempts to assist the Russian sites to develop MPC and A organizations that will operate, maintain, and continue to improve the systems and procedures. Future assistance will strive to understand and incorporate culturally sensitive approaches so that the sites take ownership for all MPC and A matters. This paper describes the efforts of the sustainability program to date

Materialism, which is the tendency to be more concerned with material values through rational experimentation and discourse. This paper applies Foucault’s genealogy to explain that materialism is a product of a series of historical events that are closely related to the practice of accounting. Second, accounting and “scientific materialism” have been instrumental in paving the course to their and our common failure. Third, the paper proposes a shift away from our impulse for a mere material existence leading to what has now become ‘popular culture’, to a vision of enhancing ‘an ever advancing civilization’.

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.

    Lead Lithium Ceramic Breeder (LLCB) Test Blanket Module (TBM) will be tested in ITER for performance evaluation of high grade of heat extraction and tritium breeding. The bred tritium in the breeder materials is extracted and recovered by Tritium Extraction System (TES), whereas tritium permeated from breeder materials to helium coolants, viz., primary coolant and secondary coolant, is recovered by Coolant Purification System (CPS). This recovered tritium has to be accounted before transferring it to tritium plant (i.e., ITER inner fuel). This tritium accountancy is performed by Tritium Accountancy System (TAS). In addition to tritium accountancy, TAS also provides necessary data for the validation of design and modelling tools.In this work, we have presented conceptual design of TAS. It also describes operational philosophy, process parameters, process flow diagram, and interface details with ITER tritium plant. (author)

  10. Development of a methodology to evaluate material accountability in pyroprocess

    sampling calculated by the central limit theorem and the Geary-Hinkley transformation. Then, the uncertainty propagation through the key-pyroprocess is conducted to analyze the Material Unaccounted For (MUF), which is a random variable defined as a receipt minus a shipment of a process, in the system. The random variable, LOPu, is defined for evaluating the non-detection probability at each Key Measurement Point (KMP) as the original Pu mass minus the Pu mass after a missing scenario. A number of assemblies for the LOPu to be 8 kg is considered in this calculation. The probability of detection for the 8 kg LOPu is evaluated with respect the size of granule and powder using the event tree analysis and the hypothesis testing method. We can observe there are possible cases showing the probability of detection for the 8 kg LOPu less than 95%. In order to enhance the detection rate, a new Material Balance Area (MBA) model is defined for the key-pyroprocess. The probabilities of detection for all spent fuel types based on the new MBA model are greater than 99%. Furthermore, it is observed that the probability of detection significantly increases by increasing granule sample sizes to evaluate the Pu-to-244Cm-ratio before the key-pyroprocess. Based on these observations, even though the Pu material accountability in pyroprocess is affected by the non-uniformity of nuclide composition when the Pu-to-244Cm-ratio method is being applied, that is surmounted by decreasing the uncertainty of measured ratio by increasing sample sizes and modifying the MBAs and KMPs.

    Preliminary concepts are presented for improved materials measurement and accounting in large critical facilities. These concepts will be developed as part of a study that will emphasize international safeguarding of critical facilities. The major safeguards problem is the timely verification of in-reactor inventory during periods of reactor operation. This will require a combination of measurement, statistical sampling, and data analysis techniques. Promising techniques include integral measurements of reactivity and other reactor parameters that are sensitive to the total fissile inventory, and nondestructive assay measurements of the fissile material in reactor fuel drawers and vault storage canisters coupled with statistical sampling plans tailored for the specific application. The effectiveness of proposed measurement and accounting strategies will be evaluated during the study

  18. Decision-directed materials-accounting procedures: an overview

    Shipley, J.P.

    1981-01-01

    With materials balances taken at intervals, methods for treating materials balance data and their use by safeguards decision-making are relatively straightforward. The emphasis on accounting in which balances may be drawn on a daily or weekly basis, raises anew questions in these two areas: (1) what is the most effective means of extracting the maximum amount of information; and (2) how should safeguards decision-makers use the results, and what impact does the decision process have on the analysis techniques. These questions lead to considering combinations of materials balances, which exposes a whole new set of concerns. For example, we must select the most appropriate combinations, which implies some consideration of possible diversion scenarios, such as abrupt or protracted. Control of the overall false-alarm rate is an important requisite of the composite procedure. Significant work has been done on loss estimators, but their role in the materials accounting decision process has only begun to be examined. Current criteria may require periodic statements with respect to materials loss; the analysis procedures must be structured to provide such information. This paper presents an overview of the current technology. Questions still to be answered are pointed out

    India has an item specific Safeguards Agreement, INFCIRC/754 with the IAEA and a nuclear material accounting system which generates the monthly reports for the Agency promptly. Subsequent to entry into force of subsidiary arrangements to INFCIRC/754 and as a part of implementation of new reporting Structure, India is developing new software to cater to its NUMAC reporting requirement. This paper gives the details of the software wherein the requirement of reporting for each of its facility to the Nuclear Controls & Planning Wing (NCPW) and the State level report to IAEA. The software is being developed on Linux (Ubuntu) OS, Mysql database and PHP. All the components are based on open source software and is developed as a two module system. The first module is for facility and the second one is for State level reports. The application has multi-level security for both the modules. Additionally, the facility level module is hardware interlocked. The facility reporter module generates a pdf file for the facility authority to sign, authenticate and hard copy filing. It can generate another xml file with an encryption, which can be sent to the State authority. In the State level module, the State authority generates reports for the Agency from xml file so received (after decryption and verification with the facility after receiving the signed hard copy) and also appends to its national database with all the information. The National database has all the information whereas the facility database has local information. The State module, in turn generates a pdf file, authenticate the same with signature of the authorized signatory (either in hardcopy form or in electronic form with PGP encryption as required by IAEA) and sends the same to the Agency. All the necessary security precautions to protect the entire NUMAC and safeguards information. (author)

  3. Energy accounting and optimization for mobile systems

    Science.gov (United States)

    Dong, Mian

    Energy accounting determines how much a software process contributes to the total system energy consumption. It is the foundation for evaluating software and has been widely used by operating system based energy management. While various energy accounting policies have been tried, there is no known way to evaluate them directly simply because it is hard to track every hardware use by software in a heterogeneous multi-core system like modern smartphones and tablets. In this thesis, we provide the ground truth for energy accounting based on multi-player game theory and offer the first evaluation of existing energy accounting policies, revealing their important flaws. The proposed ground truth is based on Shapley value, a single value solution to multi-player games of which four axiomatic properties are natural and self-evident to energy accounting. To obtain the Shapley value-based ground truth, one only needs to know if a process is active during the time under question and the system energy consumption during the same time. We further provide a utility optimization formulation of energy management and show, surprisingly, that energy accounting does not matter for existing energy management solutions that control the energy use of a process by giving it an energy budget, or budget based energy management (BEM). We show an optimal energy management (OEM) framework can always outperform BEM. While OEM does not require any form of energy accounting, it is related to Shapley value in that both require the system energy consumption for all possible combination of processes under question. We provide a novel system solution that meet this requirement by acquiring system energy consumption in situ for an OS scheduler period, i.e.,10 ms. We report a prototype implementation of both Shapley value-based energy accounting and OEM based scheduling. Using this prototype and smartphone workload, we experimentally demonstrate how erroneous existing energy accounting policies can

  5. 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

    1995-01-01

    In accordance with the definition of a Material Balance Area (MBA) as a well-defined geographical area involving an Integral operation, the building housing the BFS-1 and BFS-1 critical facilities is considered to consist of one MBA. The BFS materials are in the form of small disks clad in stainless steel and each disk with nuclear material has its own serial number. Fissile material disks in the BFS MBA can be located at three key monitoring points: BFS-1 facility, BFS-2 facility and main storage of BFS fissile materials (storage 1). When used in the BFS-1 or BFS-2 critical facilities, the fissile material disks are loaded in tubes (fuel rods) forming critical assembly cores. The following specific features of the BFS MBA should be taken into account for the purpose of computerized accounting of nuclear material: (1) very large number of nuclear material items (about 70,000 fissile material items); and (2) periodically very intensive shuffling of nuclear material items. Requirements for the computerized system are determined by basic objectives of nuclear material accounting: (1) providing accurate information on the identity and location of all items in the BFS material balance area; (2) providing accurate information on location and identity of tamper-indicating devices; (3) tracking nuclear material inventories; (4) issuing periodic reports; (5) assisting with the detection of material gains or losses; (6) providing a history of nuclear material transactions; (7) preventing unauthorized access to the system and data falsification. In August 1995, the prototype computerized accounting system was installed on the BFS facility for trial operation. Information on two nuclear material types was entered into the data base: weapon-grade plutonium metal and 36% enriched uranium dioxide. The total number of the weapon-grade plutonium disks is 12,690 and the total number of the uranium dioxide disks is 1,700

    Full Text Available Information has always presented an important factor of human activity. As a resource that guided human activity, information was gathered, stored, analysed and distributed in different ways throughout the history. Today, information system is a necessity in the global business system. Globalisation processes have changed the traditional concept of doing business and brought about the need for information management as an integral part of overall company assets and rapid development of information and communication technology. Regardless of the benefits and advantages that may be offered by the systems, companies do business to earn profit. In this sense information systems should be considered as investment. Although investment costs can be determined relatively precisely, benefits offered by the systems are more difficult to measure and they require comprehensive consideration of all aspects of doing business to which the systems refer. Accounting is an information subsystem of the single information system of a company. Its purpose is to provide comprehensive, systematic and permanent presentation of data and information, based on documents that refer to all elements contained in business subsystems and the business system of the company as a whole. Information resulting from accounting and information system is contained in accounting reports, i.e. calculations, estimates and analyses within which it is presented to the management.

    1987-01-01

    The reprocessing plants currently under International Atomic Energy Agency (IAEA) safeguards have design capacities up to 210 tonnes of heavy metal per year. All of the plants use conventional materials accounting for safeguards. However, several larger commercial reprocessing plants are being designed with capacities of 350 to 1200 tonnes of heavy metal per year. It is likely that many of these plants, as well as some of the existing smaller ones, will adopt near-real-time materials accounting. The major effect of the combination of larger plants and near-real-time accounting on IAEA safeguards will be the demand for greater timeliness of verification. Continuous inspector presence may be required, as well as more on-site measurements by the inspector. In this paper, the authors review what needs to be verified, as well as current inspector activities in the process area. The bulk of the paper describes rapid, easy-to-use measurement techniques and instruments that may be applied to on-site verification measurements

    A safeguards neutron coincidence counter for nuclear material accountancy of the Advanced spent-fuel Conditioning Process Facility (ACPF), known as the ACP Safeguards Neutron Counter (ASNC), was upgraded to improve its remote-handling and maintenance capabilities. Based on the results of the previous design study, the neutron counter was completely rebuilt, and various detector parameters for neutron coincidence counting (i.e., high-voltage plateau, efficiency profile, dead time, die-away time, gate length, doubles gate fraction, and stability) were experimentally determined. The measurement data showed good agreement with the MCNP simulation results. To the best of the authors' knowledge, the ASNC is the only safeguards neutron coincidence counter in the world that is installed and operated in a hot-cell. The final goals to be achieved were (1) to evaluate the uncertainty level of the ASNC in nuclear material accountancy of the process materials of the oxide-reduction process for spent fuels and (2) to evaluate the applicability of the neutron coincidence counting technique within a strong radiation field (e.g., in a hot-cell environment).

  14. Nuclear material safeguards surveillance and accountancy by isotope correlation techniques

    1981-11-01

    The purpose of this study is to investigate the applicability of isotope correlation techniques (ICT) to the Light Water Reactor (LWR) and the Liquid Metal Fast Breeder Reactor (LMFBR) fuel cycles for nuclear material accountancy and safeguards surveillance. The isotopic measurement of the inventory input to the reprocessing phase of the fuel cycle is the primary direct determination that an anomaly may exist in the fuel management of nuclear material. The nuclear materials accountancy gap which exists between the fabrication plant output and the input to the reprocessing plant can be minimized by using ICT at the dissolver stage of the reprocessing plant. The ICT allows a level of verification of the fabricator's fuel content specifications, the irradiation history, the fuel and blanket assemblies management and scheduling within the reactor, and the subsequent spent fuel assembly flows to the reprocessing plant. The investigation indicates that there exist relationships between isotopic concentration which have predictable, functional behavior over a range of burnup. Several cross-correlations serve to establish the initial core assembly-averaged composition. The selection of the more effective functionals will depend not only on the level of reliability of ICT for verification, but also on the capability, accuracy and difficulty of developing measurement methods. The propagation of measurement errors on the correlation functions and respective sensitivities to isotopic compositional changes have been examined and found to be consistent with current measurement methods

  17. Energy accounting in nuclear power systems

    International Nuclear Information System (INIS)

    Symonds, J.L.; Essam, P.; Stocks, K.

    1976-01-01

    Energy analysis is a systematic way of tracing and accounting for the flows of energy through an industrial system and apportioning a quantity of the primary energy input to each of the goods and services sent out. The application of energy accounting to nuclear power stations and their growth in generating systems is discussed. Misunderstandings arising from discrepancies and weaknesses in some published simple analyses of hypothetical growth situations are outlined. Results of a more complex energy flow analysis are used to demonstrate that current nuclear energy programs are running at an energy profit. Large fossil fuel savings will occur in a real electrical grid system under anticipated nuclear power growth rates. These savings will give a new dimension in planning the use of fossil energy resources which will still be needed for transport and industrial processes, such as steelmaking, for some time to come.

    Full Text Available The expansion of opportunities and the disappearance of country borders make the answering the question increasingly urgent that which country’s or region’s acts and customs as precedents the accounting created for measuring the economic performance should use in the future. The fact makes this question especially interesting that these acts and customs often differ from each other significantly even within a region. The objective of the study is to introduce the major accounting systems (US GAAP, EU directives, IFRS and their supporting institutional background in a conception way with a special regard on compiling financial statements on the basis of IFRS. The accounts should include not only validity but the preciseness expected by both the owners and the creditors focusing on consistency, the usefulness, transparency and unambiguousness of the contained pieces of information. All these are especially important when a given enterprise or an enterprise-group represents itself in several countries or continents. The actuality of the topic is strengthened by the fact that more and more entities being interested even in abroad require to use a system based on internationally accepted standards as a basis when compiling annual accounts and consolidation for the sake of comparability.

    There are currently many initiatives underway within the Department of Energy (DOE) to safely and securely manage large plutonium inventories arising from weapons dismantlement, changing missions and facility operations. Plutonium inventory information is increasingly accessible to the public as a result of the secretary of energy's openness initiative. As a result, knowledge of these inventories and levels to which the department has accounted for and controlled these inventories, will be under increased scrutiny from a variety of interest groups. The quality of this accountability data and what this data means will greatly influence the public's perception of how the US is protecting its plutonium inventories. In addition, the department's safeguards program provides an essential basis for the application of International Atomic Energy Agency (IAEA) safeguards that, in addition to possibly other international control regimes, will be in place over a large portion of these future inventories. The capability and functionality of the department's nuclear safeguards program will be important contributors to the success of US programs for the responsible stewardship of these vast plutonium inventories.

    The article is an analysis of the problem of incorporating the environment in the national accounting system as an essential part of a country's revenue. Revenue is defined here as the value which is necessary for the prudent management of a nation's expenses and balances. After a first analysis of the importance of properly structuring national accounting systems, methods used in certain countries such as France, Japan and Germany were considered in order to single out the limitations and merits of these methods. The purpose is to find a standard method which would allow for comparison with the situation in various countries and, in this way, indicate directives for better management of the environment in all of its aspects

    1991-01-01

    In a modern MOX Fuel Fabrication Plant, with a large throughput of nuclear materials, computerized real-time accountancy systems are applied. Following regulations and prescriptions imposed by the Inspectorates EURATOM-IAEA, the State and also by internal plant safety rules, the accountancy is kept in plutonium element, uranium element and 235 U for enriched uranium. In practice, Safeguards Authorities are concerned with quantities of the element (U tot , Pu tot ) and to some extent with its fissile content. Custom Authorities are for historical reasons, interested in fissile quantities (U fiss , Pu fiss ) whereas owners wish to recover the energetic value of their material (Pu equivalent). Balancing the accountancy simultaneously in all these related but not proportional units is a new problem in a MOX-plant where pool accountancy is applied. This paper indicates possible ways to solve the balancing problem created by these different units used for expressing nuclear material quantities

    Full Text Available Economic entities accuse current managerial accounting instruments due to their used indicators, their post operativeness, and their lack of necessary adjustments, short-term target, information handling and decisions taken for various reasons, except the efficiency one. In order to manage a more and more complex organization, located in an uncertain environment, managers require a permanent, real-time, information system. There is no longer sufficient the simple retrospective measurement of results, as there should be provided those instruments that support the decision making process throughout the strategic and operational processes. The implementation of a managerial accounting tool will always interact with the human behavioural dimension. In the initial stage, the actors of an organization will initially manifest reactions of difficult acceptance or even rejection. Each of them will adopt that behaviour which ensures the maximization of its own goals, even if these are, or not, convergent with the organizational objectives.

    Sewage works facilities consist of various assets groups. And there are many kinds of financial resources. In order to optimize the maintenance plan, and to secure the stability and sustainability of sewage works management, it is necessary to carry out financial simulation based on the life-cycle cost analysis. Furthermore, it is important to develop management accounting system that is interlinked with the financial accounting system, because many sewage administration bodies have their financial accounting systems as public enterprises. In this paper, a management accounting system, which is designed to provide basic information for asset management of sewage works facilities, is presented. Also the applicability of the management accounting system presented in this paper is examined through financial simulations.

    1991-01-01

    As a consequence of facility efforts to better understand inventory differences (IDs) and the desire to comply with related regulatory requirements, propagation of uncertainties has received much attention in recent years. This paper reviews several issues regarding software for ID evaluation. Some of these issues are generic (e.g., the importance of identifying individual measured values and individual special nuclear material items by name and the generality needed to handle a wide variety of accounting problems) and others are facility-specific (e.g., interfacing the facility's database to a variance propagation engine and subsequent uses of that engine). In this paper the history of a Los Alamos engine, MAWST, is briefly reviewed and some of the lessons learned during its development are described. Major hurdles to implementation do not involve shortcomings in software or in statistical theory

    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)

    Whiteson, R.; Hench, K.; Yarbro, T.; Baumgart, C.

    1998-01-01

    The Automated MC and A Database Assessment project is aimed at improving anomaly and error detection in materials control and accountability (MC and A) databases and increasing confidence in the data that they contain. Anomalous data resulting in poor categorization of nuclear material inventories greatly reduces the value of the database information to users. Therefore it is essential that MC and A data be assessed periodically for anomalies or errors. Anomaly detection can identify errors in databases and thus provide assurance of the integrity of data. An expert system has been developed at Los Alamos National Laboratory that examines these large databases for anomalous or erroneous data. For several years, MC and A subject matter experts at Los Alamos have been using this automated system to examine the large amounts of accountability data that the Los Alamos Plutonium Facility generates. These data are collected and managed by the Material Accountability and Safeguards System, a near-real-time computerized nuclear material accountability and safeguards system. This year they have expanded the user base, customizing the anomaly detector for the varying requirements of different groups of users. This paper describes the progress in customizing the expert systems to the needs of the users of the data and reports on their results

  1. Improving Materials Accountancy for Reprocessing using hiRX

    International Nuclear Information System (INIS)

    Cipiti, B.; McDaniel, M.; Havrilla, G.

    2015-01-01

    The High Resolution X-ray (hiRX) technology has the potential to replace K-Edge and Hybrid K-Edge Densitometry (HKED) for routine accountability measurements in reprocessing. This technology may significantly reduce plutonium measurement uncertainty in a simpler and less costly instrument. X-ray optics are used to generate monochromatic excitation of a sample and selectively collect emitted X-rays of the target elements. The result is a spectrum with a peak specific to one element with negligible background. Modeling was used to examine how safeguards could be improved through the use of hiRX at existing aqueous reprocessing plants. This work utilized the Separation and Safeguards Performance Model (SSPM), developed at Sandia National Laboratories, to examine how reduced measurement uncertainty decreases the overall inventory difference measurement error. Material loss scenarios were also modelled to determine the effect on detection probability for protracted diversion of nuclear material. Current testing of hiRX is being used to inform the modelling effort, but a 0.1% measurement uncertainty for uranium and plutonium concentration is an optimistic goal based on laboratory results. Modeling results showed that a three-fold improvement in the ability to detect a protracted diversion of plutonium may be possible if the 0.1% uncertainty goal can be achieved. The modelling results will be presented along with a discussion of the current experimental campaign results. In addition, a qualitative cost analysis will be presented to compare the use of hiRX with HKED. (author)

    Theoretical investigations and system studies indicate safeguards material balance data from reprocessing plants can be used to detect unauthorized removals. Plant systems have been modeled and simulated data used to demonstrate the techniques. But how sensitive are the techniques when used with actual plant data. What is the effect of safeguards applications on plant operability. Can safeguards be acceptable to plant operators, and are there any benefits to be derived. The Barnwell Nuclear Fuel Plant (BNFP) has been devoted to answering these and other questions over the past several years. A computerized system of near-real-time accounting and in-process inventory has been implemented and demonstrated during actual plant test runs. Measured inventories and hourly material balance closures have been made to assess safeguards in an operating plant application. The tests have culminated in actual removals of material from the operating plant to investigate the response and measure the sensitivity of the safeguards and data evaluation system

    The condition of a nuclear material control and accountability system (MC and A) and its individual components, as with any system combining technical elements and documentation, may be characterized through an aggregate of values for the various parameters that determine the system's ability to perform. The MC and A system's status may be functioning effectively, marginally or not functioning based on a summary of the values of the individual parameters. This work included a review of the following subsystems, MC and A and Detecting Material Losses, and their respective elements for the material control and accountability system: (a) Elements of the MC and A Subsystem - Information subsystem (Accountancy/Inventory), Measurement subsystem, Nuclear Material Access subsystem, including tamper-indicating device (TID) program, and Automated Information-gathering subsystem; (b) Elements for Detecting Nuclear Material Loses Subsystem - Inventory Differences, Shipper/receiver Differences, Confirmatory Measurements and differences with accounting data, and TID or Seal Violations. In order to detect the absence or loss of nuclear material there must be appropriate interactions among the elements and their respective subsystems from the list above. Additionally this work includes a review of regulatory requirements for the MC and A system component characteristics and criteria that support the evaluation of the performance of the listed components. The listed components had performance testing algorithms and procedures developed that took into consideration the regulatory criteria. The developed MC and A performance-testing procedures were the basis for a Guide for MC and A Performance Testing at the material balance areas (MBAs) of State Scientific Center of the Russian Federation - Institute for Physics and Power Engineering (SSC RF-IPPE).

  4. Statistical methods in nuclear material accountancy: Past, present and future

    International Nuclear Information System (INIS)

    Pike, D.J.; Woods, A.J.

    1983-01-01

    The analysis of nuclear material inventory data is motivated by the desire to detect any loss or diversion of nuclear material, insofar as such detection may be feasible by statistical analysis of repeated inventory and throughput measurements. The early regulations, which laid down the specifications for the analysis of inventory data, were framed without acknowledging the essentially sequential nature of the data. It is the broad aim of this paper to discuss the historical nature of statistical analysis of inventory data including an evaluation of why statistical methods should be required at all. If it is accepted that statistical techniques are required, then two main areas require extensive discussion. First, it is important to assess the extent to which stated safeguards aims can be met in practice. Second, there is a vital need for reassessment of the statistical techniques which have been proposed for use in nuclear material accountancy. Part of this reassessment must involve a reconciliation of the apparent differences in philosophy shown by statisticians; but, in addition, the techniques themselves need comparative study to see to what extent they are capable of meeting realistic safeguards aims. This paper contains a brief review of techniques with an attempt to compare and contrast the approaches. It will be suggested that much current research is following closely similar lines, and that national and international bodies should encourage collaborative research and practical in-plant implementations. The techniques proposed require credibility and power; but at this point in time statisticians require credibility and a greater level of unanimity in their approach. A way ahead is proposed based on a clear specification of realistic safeguards aims, and a development of a unified statistical approach with encouragement for the performance of joint research.

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

    Full Text Available There are many cases, where we may wish to choose a good accounting system and would like to learn how they work and the advantages and disadvantages of each so we can choose the better one for a business. In this paper, we present an empirical survey to understand whether we can choose accrual or cash accounting system. The proposed study designs a questionnaire among 220 experts in area of accounting affairs. The survey considers four sub hypotheses and one main hypothesis to see whether there are reliable rules and regulations in accrual-based accounting compared with cash accounting or not. Similarly, the survey investigates whether accrual-based accounting is more informative, comprehensive and provides better comparative results compared with cash accounting. The results indicate that accrual-based account performs better in terms of all mentioned criteria and it is a better method for managing accounting affairs compared with cash accounting systems.

  14. Toward a System of Global Accountability

    International Nuclear Information System (INIS)

    2016-01-01

    Post-Fukushima, the public expects and demands that nuclear regulators and operators worldwide have used lessons learned to identify and implement important actions and measures to prevent a similar event from happening again. Considerable work has been done at the national and international levels to achieve this. However, verifying the adequacy and appropriateness of measures taken in each country requires an enhanced level of global accountability that does not presently exist. The current global nuclear regulatory safety framework is based on the principle of national sovereignty and the result is that the world lacks a forum for publicizing safety concerns, beyond the national regulator, to the highest levels of government within member states. This runs the risk of significant deficiencies or non-compliance with internationally approved practices continuing unchecked even though some parties are aware of them. This also applies to flagging cases of insufficiently independent regulators or identifying inadequately prepared regulators in new nuclear countries. There are many vehicles for enhancing this transparency, e.g., WANO/INPO, regional regulatory fora, and international organizations including the OECD/NEA and IAEA. The world has never been more interconnected and it is time that the nuclear sector leverages this reality and adopts a system of global accountability for nuclear safety. (author)

    International Nuclear Information System (INIS)

    Eggers, R.F.; Wilson, R.L.; Byers, K.R.

    1981-01-01

    This paper describes a controversial but potentially beneficial MCandA strategy that has not been widely attempted in the past, called Self-Test. In this strategy a processor of Strategic Special Nuclear Material (SSNM) devises a program of internally administered tests to determine if the MCandA system performs in a reliable, expedient manner in the face of a simulated loss or compromise. Self-Test procedures would include, for example, the actual removal of SSNM from process equipment in order to determine whether the MCandA system will detect the simulated theft. Self-Test programs have several potential problems. However, an approach with the potential for solving many of these problems has been devised and is discussed

  20. From Governmental Accounting into National Accounts: Adjustments Diversity and Materiality with Evidence from the Iberian Countries’ Central Governments

    Directory of Open Access Journals (Sweden)

    Maria Antónia Jorge de Jesus

    2014-09-01

    Full Text Available In a context where governments around the world acknowledge a need for more informative governmental financial reporting to improve financial sustainability, the European Council is proposing that EU member states adopt International Public Sector Accounting Standards (IPSASs—which are recognized as also allowing improved reliability of government finance statistics—in all subsectors of the General Government Sector (GGS. Consequently, the Governmental Accounting (GA role of running and reporting on governments’ budgets for purposes of decisionmaking and accountability is changing to include being part of the EU budgetary and monetary policy, specifically within the Euro zone. Accordingly, the objective of this paper is twofold. First, it aims to start a debate in the literature about the ability of GA as it stands across Europe to meet the European System of National and Regional Accounts (ESA requirements concerning GGS data. This assumes particular relevance in a context where the two systems have to coexist, but given that budgetary reporting (GA is the main input to ESA reporting (NA, reconciliation between the two systems is required. The second objective is of a more technical nature—empirically demonstrating the diversity and materiality of the main adjustments to be made when converting GGS data from GA into NA. This is done by using evidence for Portugal and Spain, focusing on Central Government data for the period 2006–2009 and measuring their quantitative impact on the public (budgetary deficit. We conclude that GA systems as they are across EU do not meet ESA requirements, and further alignment is therefore needed to reduce adjustments as much as possible when translating data from GA into NA. Additionally, in the case of Portugal and Spain, the main findings show that the adjustments from GA into NA present great diversity for both of these Iberian countries. As for materiality, their impact is greater in Spain, but still

  3. Computer-based safeguards information and accounting system

    International Nuclear Information System (INIS)

    1977-01-01

    Acquiring, processing and analysing information about inventories and flow of nuclear materials are essential parts of IAEA safeguards. Safeguards information originates from several sources. The information to be provided is specified in the various safeguards agreements between the States and the IAEA, including both NPT agreements and safeguards trilateral agreements. Most of the safeguards information currently received by the IAEA is contained in accounting reports from the States party to the NPT. Within the frame of the material balance concept of NPT, three types of reports are provided to the IAEA by the States: Physical Inventory Listings (PIL); Inventory Change Reports (ICR); Material Balance Reports (MBR). In addition, facility design information is reported when NPT safeguards are applied and whenever there is a change in the facility or its operation. Based on this data, an accounting system is used to make available such information as the book inventories of nuclear material as a function of time, material balance evaluations, and analysis of shipments versus receipts of nuclear material. A second source of NPT safeguards information is the inspection activities carried out in the field as a necessary counterpart for verification of the data presented by the States in their accounting reports. The processing of inspection reports and other inspection data is carried out by the present system in a provisional manner until a new system, which is under development is available. The major effort currently is directed not to computer processing but toward developing and applying uniform inspection procedures and information requirements. A third source of NPT safeguards information is advanced notifications and notifications of transfer of source materials before the starting point of safeguards. Since, however, the States are not completely aware of the need and requirement to provide these data, this is a point to be emphasized in future workshops and

    1989-01-01

    Material control and accounting takes place within an envelope of activities related to safeguards and security, as well as to safety, health, and environment, all of which need to be managed to assure that the entire nuclear fuel complex can operate in a societally accepted manner. Within this envelope the committee was directed to carry out the following scope of work: (1) Review the MCandA systems in use at selected DOE facilities that are processing special nuclear material (SNM) in various physical and chemical forms. (2) Design and convene a workshop for senior representatives from each of DOE's facilities on the flows and inventories of nuclear materials. (3) Plan and conduct a series of site visits to each of the facilities to observe first hand the processing operations and the related MCandA systems. (4) Review the potential improvement in overall safeguard systems effectiveness, as measured by expected reduction in inventory difference control limits and inventory differences for materials balance accounts and facilities, or other criteria as appropriate. Indicate how this affects the relative degree of uncertainty in the system. (5) Review the efficiency of operating the MCandA system with and without the upgrading options and assess whether upgrading will contribute further efficiencies in operation, which may reduce many of the current operations costs. Determine if the current system is cost-effective. (6) Recommend the most promising technical approaches for further development by DOE and further study as warranted.

  6. The system of account and control of logistics costs

    Directory of Open Access Journals (Sweden)

    Khayrullin Rustam Zinnatullovich

    Full Text Available The process of organization of civil engineering provides the delivery of construction materials, equipment to the civil engineering objects in the required quantities at the specified time. Effective tool for solving this problem is logistics. The basic components of logistics costs, which occupy the largest share in the sum of all logistics costs, are transportation costs and storage costs. The civil engineering industry is very promising for the use of outsourcing. The main part of works on providing material and technical resources in most cases is transferred to the outsourcing of other companies, including the group of companies forming the holding. In large holding companies the chain of movement of materials, goods and productions: purchase of materials and goods, completion materials, production structures, storage, movement, transportation, etc. may include several companies belonging in holding. The goods can be moved from one warehouse to another, with or without change of the owner of goods. Each company is obliged to show each movement of goods in their financial accounting. During the goods’ movement within a group of companies from one storage to another, from one owner to another, the total costs of the goods rise. Sales within a group of companies lead, as a rule, to a gain by one of the companies and the logistic expenses of another company. Selling to a consumer provides a profit to the seller company. Therefore, the problem of adequate allocation of logistics expenses and profits between separate legal entity and the task of continuous accounting and control of logistics costs and earnings in large companies, is vital. The automated system for accounting and controlling of logistics costs is suggested. The developed system allows controlling logistics costs of refining, storage and transportation for each ton, pieces, linear or square meters of the shipped cargoes. The System is based on complex algorithms of distribution

    While CANDU reactors differ from LWRs quite markedly in the way they operate, the principles of materials accounting and safeguards are equally applicable. Indeed, since CANDU fuel is not reprocessed, the relatively simple procedure of item accounting is sufficient for CANDUs. However, on-power refueling means that automatic item counting is needed to independently confirm operator records. Surveillance and sealing techniques for spent fuel are needed for a practical system. The equipment developed has allowed the IAEA to apply safeguards at reasonable cost and with minimal interference to the utility operating the station

  9. A database model for evaluating material accountability safeguards effectiveness against protracted theft

    International Nuclear Information System (INIS)

    Sicherman, A.; Fortney, D.S.; Patenaude, C.J.

    1993-07-01

    DOE Material Control and Accountability Order 5633.3A requires that facilities handling special nuclear material evaluate their effectiveness against protracted theft (repeated thefts of small quantities of material, typically occurring over an extended time frame, to accumulate a goal quantity). Because a protracted theft attempt can extend over time, material accountability-like (MA) safeguards may help detect a protracted theft attempt in progress. Inventory anomalies, and material not in its authorized location when requested for processing are examples of MA detection mechanisms. Crediting such detection in evaluations, however, requires taking into account potential insider subversion of MA safeguards. In this paper, the authors describe a database model for evaluating MA safeguards effectiveness against protracted theft that addresses potential subversion. The model includes a detailed yet practical structure for characterizing various types of MA activities, lists of potential insider MA defeat methods and access/authority related to MA activities, and an initial implementation of built-in MA detection probabilities. This database model, implemented in the new Protracted Insider module of ASSESS (Analytic System and Software for Evaluating Safeguards and Security), helps facilitate the systematic collection of relevant information about MA activity steps, and ''standardize'' MA safeguards evaluations

    Detailed accounting and reporting procedures used by Atomic Energy of Canada Limited (AECL) for maintaining adequate records and control of heavy water supplies and stocks of fissionable materials are described, along with the duties and responsibilities of those administering the system. An appraisal is made of these procedures with respect to their adaptability for use in rapidly expanding research and power programmes. In particular the use of electronic data processing equipment is evaluated. A senior management committee is responsible for ensuring that there is a proper system for recording, reporting and controlling fissionable materials. The Production Planning and Control Branch (Pp and C B) of the Operations Division at the Chalk River Nuclear Laboratories (CRNL) is responsible to the committee for keeping the over-all records and for the general administration of the system. The duties involved are detailed in the report. The system for fissionable materials is segregated into several accountability units 15 of which are allocated to AECL departments and the others to Canadian industries and research organizations. A control ledger is kept by PP and CB for each of the units; however, the units are responsible for preparing detailed accounts of all material under their jurisdiction. The basic recording procedures covering the movement Of materials between units, the changing of forms within units, the handling of gains and losses, and disposals, are outlined in the report. The transfer of this data to IBM cards, the ultimate processing through an IBM 1401 computer and the preparation of reports for management approval are described. The heavy-water accounting system based on the same principles as used for the fissionable materials is explained. In this case the control ledger lists the pounds of D{sub 2}O allocated to each of the 15 accountability units. Again the basic recording methods and the use of a computer system are outlined.

    Different procedures are used by the realization of nuclear material check by the IAEA. The criticality check belongs to these methods and it appropriates especially to verification of the nuclear material inventory of reactors. General aspects of the applicability of this check procedure are formulated and application criteria are deduced. By the example of solid-moderated homogeneous zero-power reactors it is demonstrated the unsecurity which is to be reckoned by applying the criticality check. Finally a possibility for the reduction of errors in core material determination by additional measuring methods without questioning the criticality check method is presented. (author)

    Gryazev, V.M.; Gadzhiev, G.I.; Alekseev, I.N.

    1979-01-01

    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)

    1997-01-01

    The Urals Electrochemical Integrated Plant (UEIP) is the Russian Federation's largest uranium enrichment plant and one of three sites in Russia blending high enriched uranium (HEU) into commercial grade low enriched uranium. UEIP is located approximately 70 km north of Yekaterinburg in the closed city of Novouralsk (formerly Sverdlovsk- 44). DOE's MPC ampersand A program first met with UEIP in June of 1996, however because of some contractual issues the work did not start until September of 1997. The six national laboratories participating in DOE's Material Protection Control and Accounting program are cooperating with UEIP to enhance the capabilities of the physical protection, access control, and nuclear material control and accounting systems. The MPC ampersand A work at UEIP is expected to be completed during fiscal year 2001

    1990-02-01

    The application of near real time accountancy to nuclear material balance data can be performed effectively only with the help of computerised nuclear material accounting and information systems. Two computer programmes are introduced: DIDI, a programme for computing the MUF series and the measurement model of a reprocessing plant which is assumed to be a one-block model from data resulting from the routine operation of the facility, and PROSA, a programme for statistical analysis of NRTA data, which evaluates the MUF series on the basis of the measurement model. After the presentation of the two computer programmes two examples with realistic balance data will demonstrate the application of NRTA measures. Furthermore, some new remarks on the precision of Monte-Carlo simulations are mentioned which provide a substantial better estimation. (orig.) [de

    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

    Industrial symbiosis is a collaboration of several industries to share their necessities such material, energy, technology as well as waste management. As a part of industrial ecology, in principle, this system attempts to emulate ecosystem where waste of an organism is being used by another organism, therefore there is no waste in the nature. This system becomes an effort to optimize resources (material and energy) as well as minimize waste. Considerable, in a symbiosis incure material and energy flows among industries. Material and energy in an industry are known as cost carriers, thus flow analysis in this system can be conducted in perspective of material, energy and cost, or called as material flow cost accounting (MFCA) that is an economic and ecological appraisal approach. Previous researches shown that MFCA implementation could be used to evaluate an industry's environmental-related efficiency as well as in planning, business control and decision making. Moreover, the MFCA has been extended to assess environmental performance of SMEs Cluster or industrial symbiosis in SMEs Cluster, even to make preliminary design of an industrial symbiosis base on a major industry. This paper describes the use of MFCA to asses performance of SMEs industrial symbiosis and to improve the performance.

    1982-01-01

    Materials accountancy and control at power reactors is an integrated part of the Swedish National System of Accuntancy and Control of Nuclear Materials. The nuclear material is stratified on the basis of measurement accuracy. The physical form of the material makes item accountability applicable on the rod level. Consequently, fuel assembly dismantling and fuel rod exchanges present special problems. Both physical inventory verification and the shipment of irradiated fuel are extensive operations involving inspections and controls on inventory records and fuel elements. A method for nondestructive measurement of irradiated fuel is under development in cooperation with the IAEA. The method has been tested at a reactor station with encouraging results. An away from reactor storage facility for spent fuel is under construction in Sweden. Optical verificationof each fuel element at all times is one of the basic facility control requirements. The receiving/shipping area of the storage facility is being designed and equipped to make NDA-measurements feasible. The overlal cooperation with the IAEA in matters related to safeguarding power reactors is proceeding smoothly. There are, however, some differences of opinion, for example, as regards material stratification (Key Measurement Points) and verification procedures

    2015-03-01

    Full Text Available Financial and accounting information systems, today, no longer are the traditional ones, they are subject to the normalisation and harmonisation, in the idea of globalization, and as a natural consequence of this situation, the users of accounting information require more and more diverse information from these systems. The economic entities in general, and those in the trade, in particular, performance management, management of the current situation, with multiple phenomena of crisis, require substantiation of decisions on the basis of a system of real information, pertinent, relevant and provided in a timely manner (Radu, 2011 [7]. Apart from users and goals of information provided by entities of the accounting information system of trade entities, they must have certain qualitative characteristics that facilitate the process of interpretation and use of accounting information. At the same time they are needed because their accounting information through its better goal, to represent the support base for the elaboration of certain decisions by those interested. In this article I propose to introduce qualitative characteristics of accounting information provided by IASB (International Accounting Standards Board, which, incidentally, have been taken up initially by the Romanian accounting regulations, with their subsequent amendments and additions, so far, because, in the end, as a conclusion, I consider that I should be noted that these qualities cannot be effective unlessin turn, the users themselves have the quality to have the knowledge required to understand the information that is intended for them.

    1985-05-01

    The Oak Ridge Y-12 Plant maintains a nuclear materials control and accountability system on a computerized network identified as DYMCAS (Dynamic Special Nuclear Materials Control and Accountability System). This near real-time system was initiated in 1976 and brought on line as the offical accountability system at Y-12 in April 1982. The system was designed to assist in the detection of diversion of special nuclear material and to provide timely and accurate accountability data for both routine and emergency inventory activities. In the approximately two and one-half years of on-line operation, the system has functioned quite satisfactorily in response to both routine and non-routine situations. The system remains dynamic in the sense that it is still being modified and upgraded to improve its response capability to the ever-evolving set of safeguards scenarios. This paper will discuss the development, operation, and future of the DYMCAS. 4 refs

    1987-01-01

    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

    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.

    1980-01-01

    Materials accounting for special nuclear material in fuel cycle facilities is implemented more efficiently by applying decision analysis methods, based on estimation and detection theory, to analyze process data for missing material. These methods are incorporated in the computer program DECANAL, which calculates sufficient statistics containing all accounting information, sets decision thresholds, and compares these statistics to the thresholds in testing the hypothesis H 0 of no missing material against the alternative H 1 that material is missing. DECANAL output provides alarm charts indicating the likelihood of missing material and plots of statistics that estimate materials loss. This program is a useful tool for aggregating and testing materials accounting data for timely detection of missing material

    1989-01-01

    Nuclear materials accountancy is the only safeguards measure that provides direct evidence of the status of nuclear materials. Of the six categories that gives rise to inventory differences, the technical capability is now in place to implement the technical innovations necessary to reduce the human error categories. There are really three main approaches to detecting anomalies in materials control and accountability (MC ampersand A) data: (1) Statistical: numeric methods such as the Page's Test, CUSUM, CUMUF, SITMUF, etc., can detect anomalies in metric (numeric) data. (2) Expert systems: Human expert's rules can be encoded into software systems such as ART, KEE, or Prolog. (3) Machine learning: Training data, such as historical MC ampersand A records, can be fed to a classifier program or neutral net or other machine learning algorithm. The Wisdom ampersand Sense (W ampersand S) software is a combination of approaches 2 and 3. The W ampersand S program includes full features for adding administrative rules and expert judgment rules to the rule base. if desired, the software can enforce consistency among all rules in the rule base

    Background: Nuclear materials accountancy must be developed for nuclear facilities, which is required by regulatory in China. Currently, there are some unresolved problems for nuclear materials accountancy of bulk nuclear facilities. Purpose: The retention values and measurement errors are analyzed in nuclear materials accountancy of Power Water Reactor (PWR) fuel plant to meet the regulatory requirements. Methods: On the basis of nuclear material accounting and evaluation data of PWR fuel plant, a deep analysis research including ratio among random error variance, long-term systematic error variance, short-term systematic error variance and total error involving Material Unaccounted For (MUF) evaluation is developed by the retention value measure in equipment and pipeline. Results: In the equipment pipeline, the holdup estimation error and its total proportion are not more than 5% and 1.5%, respectively. And the holdup estimation can be regraded as a constant in the PWR nuclear material accountancy. Random error variance, long-term systematic error variance, short-term systematic error variance of overall measurement, and analytical and sampling methods are also obtained. A valuable reference is provided for nuclear material accountancy. Conclusion: In nuclear material accountancy, the retention value can be considered as a constant. The long-term systematic error is a main factor in all errors, especially in overall measurement error and sampling error: The long-term systematic errors of overall measurement and sampling are considered important in the PWR nuclear material accountancy. The proposals and measures are applied to the nuclear materials accountancy of PWR fuel plant, and the capacity of nuclear materials accountancy is improved. (authors)

    Six US Department of Energy Laboratories are carrying out a program of cooperation with the Russian Research Center Kurchatov Institute to improve nuclear material protection, control and accounting (MPC and A) at Kurchatov. In 1997--1998 the primary thrust of this program has been directed to Building 106, which houses a number of test reactors and critical facilities. Substantial improvements in physical protection, upgrades in the physical inventory taking procedures, installation of equipment for the computerized materials accounting system, and installation of nuclear material portal monitors and neutron-based measurement equipment are being carried out at this facility. Software for the computerized accounting system, named KI-MACS, has been developed at Kurchatov and the system has been fully integrated with the bar code printing and reading equipment, electronic scales, and nondestructive assay equipment provided under this program. Additional 1997--1998 activities at Kurchatov include continuation of a tamper indicating device program, vulnerability assessments of several facilities, hosting of a Russian-American Workshop on Fissile Material Control and Accountability at Critical Facilities, and the development of accounting procedures for transfers of nuclear materials between material balance areas

    International Target Values (ITV) shows random and systematic measurement uncertainty components as a reference for routinely achievable measurement quality in the accountancy measurement. The measurement uncertainty, called error henceforth, needs to be periodically evaluated and checked against ITV for consistency as the error varies according to measurement methods, instruments, operators, certified reference samples, frequency of calibration, and so on. In the paper an error evaluation method was developed with focuses on (1) Specifying clearly error calculation model, (2) Getting always positive random and systematic error variances, (3) Obtaining probability density distribution of an error variance and (4) Confirming the evaluation method by simulation. In addition the method was demonstrated by applying real data. (author)

    Accounting for time is defined as putting a price on time. Researchers have demonstrated that accounting for time reduces the time individuals spend on others; however, its association with monetary donations has not been examined. We hypothesized that accounting for time will activate a utility mindset that would affect one's allocation of time and money. In Study 1, the mediating effect of utility mindsets on the relationship between accounting for time and prosocial behavior was examined. In Study 2, we examined the effect of accounting for time on time spent helping and donating money, and the moderating role of material values on the relationship between accounting for time and prosocial behavior. Results showed that accounting for time activated a mindset of utility maximization that, in turn, reduced participants' prosocial behavior; moreover, materialism moderated the effect of accounting for time on prosocial behavior.

    1981-01-01

    This paper presents the initial phase of the US study program and involves the computation of isotopic correlations for the LMFBR fuel cycle. The LWR fuel cycle phase of the study is currently in progress. The selection of the more safeguards effective functionals will depend not only on the level of reliability of isotope correlation technique (ICT) for verification, but also on the capability and difficulty of developing measurement methods. Performance characteristics of existing and proposed isotopic measurement techniques cover the general areas including assay and isotopic wet chemistry and NDA: (1) simultaneous multicomponent analysis techniques, (2) mass spectrometry, (3) x-ray fluorescence or densitometry with high flux monochromatic x-ray sources and high dispersion spectrometers, (4) passive and active neutron interrogation, (5) high level gamma-ray spectroscopy, (6) coulometry, and (7) potentiometry. The measurement capabilities and inherent limitations of these systems are to be evaluated in terms of total systems, operational mode, sample preparation requirements and consequent effect on dissolver solution representation, accuracy and precision estimates (if available), development status of the technique, and development requirements. The isotopic correlation technique shows considerable promise for use in verifying the initial isotopic composition and burnup of discharged assemblies based on the measured ratios of several key isotopes, obtained probably at the dissolver stage in reprocessing. This technique should, for example, easily be capable of indicating the exchange of a blanket assembly for a fuel assembly

    2012-01-01

    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.

    1999-01-01

    The advancement of the U.S. government's state system of accounting from a mainframe computer to a personal computer (PC) had been successfully completed. The accounting system, from 1965 until 1995 a mainframe application, was replaced in September 1995 by an accounting system employing local area network (LAN) capabilities and other state-of-the-art characteristics. The system is called the Nuclear Materials Management and Safeguards System (NMMSS), tracking nuclear material activities and providing accounting reports for a variety of government and private users. The uses of the system include not only the tracking of nuclear materials for international and domestic safeguards purposes but also serving to facilitate the government's resource management purposes as well. The system was converted to PC hardware and fourth generation software to improve upon the mainframe system. The change was motivated by the desire to have a system amenable to frequent modifications, to improve upon services to users and to reduce increasing operating costs. Based on two years of operating the new system, it is clear that these objectives were met. Future changes to the system are inevitable and the national system of accounting for nuclear materials has the technology base to meet the challenges with proven capability. (author)

    The materials control and accountability aspects of the reprocessing and refabrication of a conceptual large-scale HTGR fuel recycle plant have been discussed. Two fuel cycles were considered. The traditional highly enriched uranium cycle uses an initial or makeup fuel element with a fissile enrichment of 93% 235 U. The more recent medium enriched uranium cycle uses initial or makeup fuel elements with a fissile enrichment less than 20% 235 U. In both cases, 233 U bred from the fertile thorium is recycled. Materials control and accountability in the plant will be by means of a real-time accountability method. Accountability data will be derived from monitoring of total material mass through the processes and a system of numerous assays, both destructive and nondestructive

    1976-04-07

    A Material Handling System Simulator (MHSS) program is described that provides specialized functional blocks for modeling and simulation of nuclear material handling systems. Models of nuclear fuel fabrication plants may be built using functional blocks that simulate material receiving, storage, transport, inventory, processing, and shipping operations as well as the control and reporting tasks of operators or on-line computers. Blocks are also provided that allow the user to observe and gather statistical information on the dynamic behavior of simulated plants over single or replicated runs. Although it is currently being developed for the nuclear materials handling application, MHSS can be adapted to other industries in which material accountability is important. In this paper, emphasis is on the simulation methodology of the MHSS program with application to the nuclear material safeguards problem. (auth)

    Under the guidance of the Department of Energy (DOE), six DOE laboratories have initiated a new program of cooperation with the Russian Federation's nuclear institutes. The purpose of the program is to accelerate progress toward a common goal shared by both the US and Russia--to reduce the risks of nuclear weapons proliferation, including such threats as theft, diversion, and unauthorized possession of nuclear materials, by strengthening systems of nuclear materials protection, control, and accounting. This new program is called the Laboratory-to-Laboratory Nuclear Materials Protection, Control, and Accounting (Lab-to-Lab MPC and A) Program. It is designed to complement other US-Russian MPC and A programs such as the government-to-government (Nunn-Lugar) programs. The Lab-to-Lab MPC and A program began in 1994 with pilot projects at two sites: Arzamas-16 and the Kurchitov Institute. This paper presents an overview of the Laboratory-to-Laboratory MPC and A Program. It describes the background and need for the program; the objectives and strategy; the participating US and Russian laboratories, institutes and enterprises; highlights of the technical work; and plans for the next several years

    Destructive analysis for material accountancy purpose should maintain higher precision referring the International Target Value (ITV). Quality control for the analysis is effective tool to maintain the analytical precision in routine analysis as well as to improve its performance. Since isotope dilution mass spectrometry for the determination of Plutonium and Uranium content and its isotopic composition has launched in the laboratory of Plutonium Fuel Center (PFC) of JNC, comprehensive quality control system has gradually growing up, which currently consists of bias detecting, random error monitoring and human error preventing system. Preventing analysis bias is the most important to maintain long-term performance of measurement. To make bias detecting capability robust, PFC is participating to several intercomparison programs regarding DA samples. Random error monitoring system is another important system to maintain high performance of each routine analysis operation, which composes functions to detect abnormal dispersion of each result and to confirm the state of health of operation of mass spectrometers by measurement of standard materials. To avoid human error during operation process, introduction of computer control system as much extent as possible is practical approach. In this paper, the comprehensive quality control system is introduced and the experiences gained so far are summarized for discussion. (author)

    A very accurate accountability of nuclear materials is required throughout the industrial nuclear fuel cycle for technical reasons and safety purposes but also for commercial, physical protection and safeguards objectives. The present note intends to illustrate with a few samples the performance presently achieved and the major questions which the analysts are facing in these areas. The examples taken concern the accountability of feed and product materials at LWR nuclear fuel fabrication plants and spent fuel reprocessing plants. They were selected because they constitute major components of the flow and inventory of the nuclear fuel materials at key measurement points in nuclear industry. The factors limiting the quality of the assays and accountability of these industrial materials and some observations regarding the need and use of reference materials and quality control programmes in support of accurate accounting are presented. 7 refs

    1983-01-01

    The study of a near-real-time (n.r.t.) material accountancy system as applied to small or medium-sized spent fuel reprocessing facilities has been carried out since 1978 under the TASTEX programme. In this study, a model of the n.r.t. accountancy system, called the ten-day-detection-time model, was developed and demonstrated in the actual operating plant. The programme was closed on May 1981, but the study has been extended. The effectiveness of the proposed n.r.t. accountancy model was evaluated by means of simulation techniques. The results showed that weekly material balances covering the entire process MBA could provide sufficient information to satisfy the IAEA guidelines for small or medium-sized facilities. The applicability of the model to the actual plant has been evaluated by a series of field tests which covered four campaigns. In addition to the material accountancy data, many valuable operational data with regard to additional locations for an in-process inventory, the time needed for an in-process inventory, etc., have been obtained. A CUMUF (cumulative MUF) chart of the resulting MUF data in the C-1 and C-2 campaigns clearly showed that there had been a measurement bias across the process MBA. This chart gave a dramatic picture of the power of the n.r.t. accountancy concept by showing the nature of this bias, which was not clearly shown in the conventional material accountancy data.

  20. A passive automated personnel accountability system for reactor emergency preparedness

    Zimmerman, R.O.; DeLisle, G.V.; Hickey, E.E.

    1988-04-01

    In 1985 a project was undertaken at the N Reactor on the Hanford Site to develop an automated personnel accountability system to ensure accountability of all personnel within 30 minutes of a site evacuation. The decision to develop such a system was made after a full-scale evacuation drill showed that the manual accountability system in use at the time was inadequate to meet the 30-minute requirement. Accountability systems at commercial nuclear power plants were evaluated, but found to be unsuitable because they were not passive, that is, they required action on part of the user for the system to work. Approximately 2500 people could be required to evacuate the 100-N Area. Therefore, a card key system or badge exchange system was judged not to be feasible. A passive accountability system was desired for N Reactor to allow personnel to enter and leave the site in a more timely manner. To meet the need for an automated accountability system at N Reactor, a special Evacuation Accountability System (EVACS) was designed and developed. The EVACS system has three basic components: the transponder, a credit card-sized device worn with the security badge; portal monitors, which are electronically activated by the transponder; and a computer information system that contains the personnel data base. Each person wearing a transponder is accounted for automatically by walking through a portal. In this paper, a description of the hardware and software will be presented, together with problems encountered and lessons learned while adapting an existing technology to this particular use. The system is currently installed and requires acceptance testing before becoming operational

    2015-01-01

    Under safeguards agreements that the Government of Canada has with the International Atomic Energy Agency (IAEA), and nuclear cooperation agreements with other states, the Canadian Nuclear Safety Commission (CNSC) is required to track the inventory and movement of all safeguarded material. As safeguards programmes evolve, including the implementation of Integrated Safeguards, the scope of the reporting requirements for facilities within Canada has also increased. At the same time, ensuring the secure transmission of the associated data continues to be an overarching factor. The changes that are occurring in the nuclear material accounting (NMA) landscape have necessitated a modernization of Canada's accounting and reporting system, with the objective of creating a more effective and efficient system, while at the same time maintaining the security of prescribed information. After a review of the environment, the CNSC embarked on a project that would encourage facilities to transition away from traditional modes of NMA reporting and adopt an electronic approach. This paper will discuss how the changes to Canada's NMA infrastructure were identified and implemented internally to allow for optimized electronic reporting. Improvements included the development of the regulatory and guidance documents, the overhaul of the reporting forms, the upgrade of the CNSC's NMA database, and the development of an electronic reporting platform that leveraged existing technologies. The paper will also discuss the logistics of engaging stakeholders throughout the process, launching the system and soliciting feedback for future system improvements. Special consideration will be given to the benefits realized by both the CNSC and facilities who have voluntarily embraced electronic reporting. The final objective of this paper will be to identify the challenges that were faced by the CNSC and the nuclear industry as the system changes were implemented and to highlight how

    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)

    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

    Full Text Available From the last two decades of the 20th Century on, many companies have adopted production strategies that could be termed “lean manufacturing”. Lean team leaders state that traditional costing systems fail to properly assess their operational improvements and therefore ask for new cost accounting methods. The search for a new accounting paradigm has led to important applied research and several accounting methods.   In this paper we are going to show the state of the art in costing techniques used in companies that adopt lean manufacturing practices and we will be presenting an additional costing method, based on Activity-Based Costing, intended to cast light on the operational improvements achieved in companies that are just starting a maturity path towards lean manufacturing. This article examines how the approach is applied in the context of a manufacturing company.
