Title: SFCOMPO-2.0: An OECD NEA database of spent nuclear fuel isotopic assays, reactor design specifications, and operating data

Abstract

SFCOMPO-2.0 is the new release of the Organisation for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) database of experimental assay measurements. These measurements are isotopic concentrations from destructive radiochemical analyses of spent nuclear fuel (SNF) samples. We supplement the measurements with design information for the fuel assembly and fuel rod from which each sample was taken, as well as with relevant information on operating conditions and characteristics of the host reactors. These data are necessary for modeling and simulation of the isotopic evolution of the fuel during irradiation. SFCOMPO-2.0 has been developed and is maintained by the OECD NEA under the guidance of the Expert Group on Assay Data of Spent Nuclear Fuel (EGADSNF), which is part of the NEA Working Party on Nuclear Criticality Safety (WPNCS). Significant efforts aimed at establishing a thorough, reliable, publicly available resource for code validation and safety applications have led to the capture and standardization of experimental data from 750 SNF samples from more than 40 reactors. These efforts have resulted in the creation of the SFCOMPO-2.0 database, which is publicly available from the NEA Data Bank. Our paper describes the new database, and applications of SFCOMPO-2.0 for computer code validation, integralmore » nuclear data benchmarking, and uncertainty analysis in nuclear waste package analysis are briefly illustrated.« less

  • Experimental data on the isotopic concentrations in irradiated nuclear fuel represent one of the primary methods for validating computational methods and nuclear data used for reactor and spent fuel depletion simulations that support nuclear fuel cycle safety and safeguards programs. Measurement data have previously not been available to users in a centralized or searchable format, and the majority of accessible information has been, for the most part, limited to light-water-reactor designs. This paper describes a recent initiative to compile spent fuel benchmark data for additional reactor designs used throughout the world that can be used to validate computer model simulationsmore » that support nuclear energy and nuclear safeguards missions. Experimental benchmark data have been expanded to include VVER-440, VVER-1000, RBMK, graphite moderated MAGNOX, gas cooled AGR, and several heavy-water moderated CANDU reactor designs. Additional experimental data for pressurized light water and boiling water reactor fuels has also been compiled for modern assembly designs and more extensive isotopic measurements. These data are being compiled and uploaded to a recently revised structured and searchable database, SFCOMPO, to provide the nuclear analysis community with a centrally-accessible resource of spent fuel compositions that can be used to benchmark computer codes, models, and nuclear data. The current version of SFCOMPO contains data for eight reactor designs, 20 fuel assembly designs, more than 550 spent fuel samples, and measured isotopic data for about 80 nuclides.« less
  • An essential component of computational modeling and simulation is the availability of well-qualified experimental benchmark data against which calculation systems can be validated and the bias and uncertainty associated with the codes and data can be evaluated. The validation process is extremely important for safety and licensing to demonstrate that adequate margins for uncertainty have been included in the calculations. For safety evaluations involving spent nuclear fuel, the isotopic compositions and resulting activities calculated using depletion and decay codes must be validated against experimental determinations of the spent fuel content. In this process the isotopic concentrations predicted by the codesmore » should be compared with corresponding measurements of spent fuel made by destructive analysis as a fundamental part of any code performance evaluation. In recent years there has been growing international interest in acquiring high-quality assay data that can be used to validate code calculations, particularly for modern fuel designs and high burnup fuels and for a wider range of nuclides important to nuclear criticality safety, radiological safety assessments, and decay heat. Assay data are required to validate a broad range of reactor and fuel-cycle applications, including reactor core simulation, postulated severe accident analysis, spent fuel handling, spent fuel transportation and interim storage, reprocessing, nuclear safeguards, and final fuel repository evaluations. In some cases researchers working on depletion code development have noted a general lack of available assay measurements that can be used to benchmark and validate their code calculations for spent fuel compositions. This perception is due in part to the fact that data have been reported in diverse publications over many years, many experimental reports are difficult to access, and there has not been a concerted and funded effort to compile and consolidate available measurements that can be easily accessed by code developers and analysts for validation. In response to the increased interest in fuel isotopic measurements and needs for consolidation and documentation of available data, an Expert Group on Assay Data for Spent Nuclear Fuel (EGADSNF) was formed in 2007 as a working group of the Organisation for Economic Cooperation and Development (OECD)/Nuclear Energy Agency (NEA) Working Party on Nuclear Criticality Safety (WPNCS). Although the group was formed by the Expert Group on Burnup Credit to coordinate isotopic assay data activities and facilitate collaboration between countries developing or implementing burnup credit in their nuclear criticality safety methodologies, the group recognized the need and value of assay data for a broad range of spent fuel applications, and the EGADSNF includes members representing not only the WPNCS, but also members from the standing technical Committee on the Safety of Nuclear Installations and the Integration Group for the Safety Case of the Radioactive Waste Management Committee. Member countries currently active in the EGADSNF include Belgium, the Czech Republic, France, Germany, Japan, Slovakia, Spain, Sweden, the United Kingdom, and the United States. The experimental database of spent fuel measurements maintained by the OECD/NEA is web-accessible. SFCOMPO (database of Spent Fuel Compositions) contains measured isotopic data, mostly for light water reactor (LWR) fuels, for about 250 fuel samples. This paper summarizes the status of SFCOMPO and current activities to expand and improve the database.« less
  • Management of spent nuclear fuel is a key issue for many NEA member countries. In nuclear criticality safety, the decision of many countries to advance burnup credit as part of their licensing strategy has heightened recent interest in experimental data needed to validate computer codes used in burnup credit calculations. This paper discusses recent activities of an Expert Group on assay data, formed under the OECD/NEA/NSC/WPNCS (Working Party on Nuclear Criticality Safety) to help coordinate isotopic assay data activities and facilitate international collaboration between NEA member countries developing or implementing burnup credit methodologies. Recent activities of the Expert Group aremore » described, focusing on the planned expansion of the Spent Fuel Isotopic Composition Database (SFCOMPO), and preparation of a state-of-the-art report on assay data that includes sections on recommended radiochemical analysis methods, techniques, and lessons learned from previous experiments.« less
