INTER-CODE COMPARISON OF TRIPOLI? AND MVP ON THE MCNP CRIT I CALITY VALIDATION SUITE

摘要

This paper presents a joint work conducted at CEA Saclay and JAEA Tokai aimed at comparing the Monte Carlo codes TRIPOLI-4? and MVP on a selection of ICSBEP benchmarks. Our goal is to establish a common set of Monte Carlo input decks, as a basis for rigorous inter-code comparison in criticality-safety. As a reference, we will use the MCNP Criticality Validation Suite: other Monte Carlo developers might easily join this effort in the future. For the purpose of inter-code comparison, the TRIPOLI-4? and MVP input decks have been exactly translated from those of MCNP, without any further assumptions. Both TRIPOLI-4? and MVP have been run with the same ENDF/B-VII.O evaluated nuclear data and, as far as possible, the same simulation options as in the original LANL work (same initial source, same number of active and discarded cycles and neutrons per cycle).
