LCE for Research Reactor Benchmark Calculations

The purpose of this calculation is to document the MCNP4B2L V evaluations of Laboratory Critical Experiments (LCEs) performed as part of the Disposal Criticality Analysis Methodology program. LCE evaluations documented in this report were performed for 182 different cases with varied design parameters. The objective of this analysis is to quantify the MCNP4B2LV code system's ability to accurately calculate the effective neutron multiplication factor (keff) for various critical configurations.
The LCE evaluations support the development and validation of the neutronics models used for criticality analyses involving research reactor spent nuclear fuel in a geologic repository.
