- Extended neutron irradiation of certain PWR pressure vessels (PVs) causing significant degradation of vessel material mechanical and structural properties, coupled with the concern that in a PWR transient the pressure vessel may be subjected to pressurized thermal shock, has resulted in a need for accurate and well benchmarked calculations of accumulated pressure vessel fluence. This paper presents results of pressure vessel fluence benchmark calculations and comparisons with measurement data, performed as part of the BNL/NRC Pressure Vessel Embrittlement program. The benchmarking effort consisted of calculations of the fast (>1-MeV) neutron fluence for (1) the PV surveillance capsules of two Combustion Engineering reactors (CE-1, a 217-assembly plant, and CE-2, a 133-assembly plant) and a 177-assembly Babcock and Wilcox reactor (B and W-1), (2) flux measurements made in the cavity of a 177-assembly B and W reactor (B and W-2) and (3) the ORNL/PCA benchmark experiment.
