BENCHMARK TESTING OF ~(233)U EVALUATIONS

摘要

In this paper we investigate the adequacy of available ~(233)U cross-section data (ENDF/B-VI and JENDL-3) for calculation of critical experiments. An ad hoc revised ~(233)U evaluation is also tested and appears to give results which are improved relative to those obtained with either ENDF/B-VI or JENDL-3 cross sections. Calculations of K_(eff) were performed for ten fast benchmarks and six thermal benchmarks using the three cross-section sets. Central reaction-rate-ratio calculations were also performed.
