Description

Criticality calculations for BFS-1 test facility with lead were performed using Monte-Carlo code MCU-BR to verify some evaluated neutron data files for fast spectra. These data files are RUSFOND, ENDF/B-VII.1, JEFF-3.2, JENDL-4.0, CENDL-3.1 and some combined data. The continuous energy treatment (ACE format) was used. Critical assemblies include the pellets consisted from fissionable materials, lead, stainless still and other. The average Keff evaluation for each critical assembly was obtained. Standard deviation for Keff at various data files is in interval 0,1% - 0,4% with probability of 0,55 - 0,82, for average Keff evaluation standard deviation is 0,14% with probability of 0,73.
