This Working Paper contributes to the data evaluation work for the SFCOMPO database - the world’s largest open database of destructive assay data for spent nuclear fuel. The database includes measurement data for over 750 fuel samples selected from fuel irradiated in 44 reactors of 8 types. The database provides descriptions of the measured fuel samples’ characteristics and operation histories and includes datasets of measured nuclide concentrations for over 60 nuclides, key actinides and fission products, which span needs and interests of a variety of nuclear science and engineering applications, including criticality safety, reactor physics, nuclide inventory, nuclear data, decay heat, and radiation shielding.
The SFCOMPO database is maintained and developed by the Nuclear Energy Agency (NEA) and managed by the SFCOMPO Technical Review Group (TRG) by mandate from the NEA Nuclear Science Committee’s Working Party of Nuclear Criticality Safety. One of the primary missions of the SFCOMPO TRG is to perform peer-review assessment of the datasets in the database and develop high-quality benchmarks and benchmark models based on these data. Destructive assay measurement data are widely recognised as one of the most reliable bases for validating the computational tools and associated nuclear data applied for predicting nuclide inventories in irradiated nuclear fuel.
