Re-evaluation of Assay Data of Spent Nuclear Fuel obtained at Japan Atomic Energy Research Institute for validation of burnup calculation code systems

► The specifications required for the analyses of the destructive assay data taken from irradiated fuel in Ohi-1 and Ohi-2 PWRs were documented in this paper. ► These data were analyzed using the SWAT2.1 code, and the calculation results showed good agreement with experimental results. ► These destructive assay data are suitable for the benchmarking of the burnup calculation code systems.
