Abstract
Criticality benchmark testing was performed with evaluated nuclear data libraries for thermal, low-enriched uranium fuel rod applications. C/E values for k_eff were calculated with the continuous-energy Monte Carlo code MVP2 and its libraries generated from ENDF/B-VI.8, ENDF/B-VII.0, JENDL-3.3 and JEFF-3.1. Subsequently, the observed k_eff discrepancies between libraries were decomposed to specify the source of difference in the nuclear data libraries using sensitivity analysis technique. The obtained sensitivity profiles are also utilized to estimate the representativity of cold critical experiments to the boiling water reactor under hot operating condition.
