Computational benchmark on plutonium recycling in PWRs. ECN solution of OECD WPPR benchmark

摘要

The Working Party on the Physics of Plutonium Recycle decided at its startup meeting in 1993 to include benchmark exercises for plutonium usage in both thermal and fast reactors. The goal of these exercises was to establish the present status quo of the accuracy of reactor physical calculations of plutonium fuels. An indication of this accuracy was to be obtained from the spread in the results of the various contributors. One of the two benchmarks for thermal reactors concerned the evolution of the nuclear inventory of uranium-plutonium Mixed Oxide (MOX) fuels in PWRs with irradiation time. The ECN results of this benchmark, denoted as the ''Benchmark for Plutonium Recycling in PWRs'', are reported here. (orig.). (Atomindex citation 27:011188)
