Analysis of the H. B. ROBINSON-2 reactor pressure vessel dosimetry benchmark using TRIPOLI-4® Monte Carlo code

Abstract

This paper presents an analysis of the H.B. Robinson-2 reactor pressure vessel dosimetry benchmark. This benchmark is based on an experiment performed at an operating PWR (Pressurized Water Reactor). It includes measurements for both in-vessel and ex-vessel dosimeters. To enlarge the TRIPOLI-4 ® validation database of neutron attenuation in PWR, an analysis of H.B. Robinson-2 benchmark was carried out using the TRIPOLI-4 ® Monte Carlo code, the DARWIN/PEPIN2 depletion code, the general-purpose point-wise library JEFF3.1.1, and the International Reactor Dosimetry File IRDF-2002. Calculated activity values are compared with measured ones provided in this benchmark. Furthermore, calculated activity values are also compared with results obtained using two calculation schemes: the deterministic code DORT and the BUGLE-96 cross section library on the one hand, and the Monte Carlo code MCNPX and the JEFF3.1.1 cross section library on the other hand.
