Calculations for the ANS UO₂ lattice benchmark have been performed with the MCNP Monte Carlo code and its ENDF/B-V and ENDF/B-VI continuous-energy libraries. The ENDF/B-V library produces significantly better agreement with the benchmark value for k_eff than do the ENDF/B-VI libraries. However, the pin power distributions are essentially the same irrespective of the library.
