Validation of MCNP Critical Benchmark Models of Moderated Highly Enriched Uranium Slabs

摘要

The validation of the models described here contributed to the centralized LANL benchmark repository currently under development [5].While the revisions to the HEU-MET-FAST-007 model made statistically significant changes to the bias in a small set of cases, the changes were mostly negligible. Given the number of revisions made, the lack of substantial changes in the multiplication factor and bias provide additional confidence in the Whisper collection.
