Effective neutron multiplication factors for 66 critical systems were calculated in order to test the neutron data library BAS. The class of systems chosen for the keff calculations includes unreflected metal uranium and plutonium systems and systems that were reflected by 238U, Fe, Al, Ti, Pb, Be, C, CH2, and H2O. Configurations and materials used in these critical systems were taken from the "International Handbook of Evaluated Criticality Safety Benchmark Experiments." The calculations with BAS were performed using the codes PRIZMA-D and MCNP.4a. For comparison, the calculations were repeated using MCNP.4a with ENDF/B5 and ENDF/B6 cross-section data. A comparison of all results is provided.
