Comparison between calorimeter and HLNC errors

Description: This paper summarizes an error analysis that compares systematic and random errors of total plutonium mass estimated for high-level neutron coincidence counter (HLNC) and calorimeter measurements. This task was part of an International Atomic Energy Agency (IAEA) study on the comparison of the two instruments to determine if HLNC measurement errors met IAEA standards and if the calorimeter gave significantly'' better precision. Our analysis was based on propagation of error models that containe… more

Developing a brittle fracture acceptance criterion for transport casks for adoption by the International Atomic Energy Agency (IAEA)

Description: With increasing nuclear material transportation demands, new generation casks have included designs which propose the use of structural materials other than austenitic stainless steel. Motivation for using alternate materials include potentials for lower cost, easier fabrication, no welding and less weight (higher payload). Examples of candidate materials for structural components include ferritic steels and ductile cast iron for the containment boundary and borated stainless steel for the bask… more

IAEA Sodium Void Reactivity Benchmark Calculations

Description: In this paper, the IAEA-1 992 Benchmark Calculation of Sodium Void Reactivity Effect in Fast Reactor Core'' problem is evaluated. The proposed design is a large axially heterogeneous oxide-fueled fast reactor as described in Section 2; the core utilizes a sodium plenum above the core to enhance leakage effects. The calculation methods used in this benchmark evaluation are described in Section 3. In Section 4, the calculated core performance results for the benchmark reactor model are presented;… more

International Nuclear Fuel Cycle Fact Book

Description: As the US Department of Energy (DOE) and DOE contractors have become increasingly involved with other nations in nuclear fuel cycle and waste management cooperative activities, a need has developed for a ready source of information concerning foreign fuel cycle programs, facilities, and personnel. This Fact Book was compiled to meet that need. The information contained in the International Nuclear Fuel Cycle Fact Book has been obtained from many unclassified sources: nuclear trade journals and … more

The design and installation of a core discharge monitor for CANDU-type reactors

Description: A new type of surveillance systems that monitors neutron and gamma radiation in a reactor containment is being installed at the Ontario Hydro Darlington Nuclear Generating Station A, Unit 2. Unlike video or film surveillance that monitors mechanical motion, this system measures fuel-specific radiation emanating from irradiated fuel as it is pushed from the core of CANDU-type reactors. Proof-of-principle measurements have been carried out at Bruce Nuclear Generating Station A, Unit 3. The system… more

Concrete containment aging study

Description: In 1989, IAEA initiated a pilot study on the management of aging of nuclear power plant components. The Phase I and II studies of concrete containment are discussed. With the data base, plant owners will be able to review and enhance their existing programs. IAEA will analyze data provided by participating plants and the report is scheduled to be released by late 1994 (final report release mid-1995).

An efficient network for interconnecting remote monitoring instruments and computers

Description: Remote monitoring instrumentation must be connected with computers and other instruments. The cost and intrusiveness of installing cables in new and existing plants presents problems for the facility and the International Atomic Energy Agency (IAEA). The authors have tested a network that could accomplish this interconnection using mass-produced commercial components developed for use in industrial applications. Unlike components in the hardware of most networks, the components--manufactured an… more

Safeguards instruments for Large-Scale Reprocessing Plants

Description: Between 1987 and 1992 a multi-national forum known as LASCAR (Large Scale Reprocessing Plant Safeguards) met to assist the IAEA in development of effective and efficient safeguards for large-scale reprocessing plants. The US provided considerable input for safeguards approaches and instrumentation. This paper reviews and updates instrumentation of importance in measuring plutonium and uranium in these facilities.

Challenge inspections in Arms Control treaties: Any lessons for strengthening NPT verification?

Description: Recent revelations of an ongoing and sophisticated nuclear weapons development program in Iraq have lead to suggestions for strengthening International Atomic Energy Agency (IAEA) safeguards. Especially troubling was the realization that safeguards, as presently applied, could not possibly have detected such a program. It is clear that the inspections which have taken place in Iraq since the Gulf War could only have been imposed on a nation which had suffered a severe military defeat. It has, h… more

Detection of uranium enrichment activities using environmental monitoring techniques

Description: Uranium enrichment processes have the capability of producing weapons-grade material in the form of highly enriched uranium. Thus, detection of undeclared uranium enrichment activities is an international safeguards concern. The uranium separation technologies currently in use employ UF{sub 6} gas as a separation medium, and trace quantities of enriched uranium are inevitably released to the environment from these facilities. The isotopic content of uranium in the vegetation, soil, and water ne… more

Field measurements to support IAEA procedures development for fuel assembly and fuel rod active length verification

Description: The activities performed in verification of reactor fuel rods and assemblies by International Atomic Energy Agency (IAEA) safeguards inspectors include measurements of the length of the enriched uranium sections in fuel assemblies and fuel rods. These measurements are normally made with the IAEA hand-held gamma monitor (HM-4) on fuel elements containing only enriched uranium. Many fuel rods currently in use contain natural uranium end sections and several different {sup 235}U enrichment zones. … more

Radiological Assessment for the Dumping of Radioactive Wastes in the Oceans

Description: Over the last three decades or so, a number of international meetings have been convened to treat the specific problem of radioactive waste disposal into the oceans. The first of these meetings was held in 1958 at the United Nations Conference on the Law of the Sea. Immediately following, the International Atomic Energy Agency (IAEA), in the Brynielsson Report, recommended measures for ensuring that disposal of radioactive waste into the sea would not result in unacceptable hazards to man (IAEA… more
