Benchmark calculations for some Los Alamos oralloy critical experiments
In late 1976, LANL personnel performed are accurate measurement to determine the critical mass of a sphere of highly enriched uranium (oralloy) when reflected by water. This experiment has been used previously to benchmark the MCNP and KENO Monte Carlo codes. However, these benchmark calculations were performed for idealizations of the experiment and involved significant approximations. In contrast, the analysis reported herein is based on a detailed representation of the actual experiment and a set of recently published isotopic specifications for the sphere. Differences between the results from this study and those from the earlier benchmark calculations are related to specific aspects of those calculations.
