Comparative Analysis of DPA Processed from Current Evaluated Nuclear Data Libraries

Source

Recent pressure vessel surveillance reports contain DPA rates as an exposure parameter. In order to assess the reliability of the DPA data, it is useful to inter-compare available DPA data processed from current evaluated nuclear data libraries. We generated the damage energy production cross sections for elements in a RPV of a PWR and a core barrel of a LMR, with NJOY 97 code system from the currently available evaluated nuclear data libraries, ENDF/B-VI.5, JEF-2.2, JENDL-3.2, BROND-2.2, and CENDL-2.1. The DPA rates using the neutron spectra from the surveillance test of Korean PWR Ulchin Unit 1 and the design of KALIMER LMR were inter-compared. The results show a maximum relative difference of 22% for carbon steel in a PWR. The effect of partial damage cross sections such as elastic scattering, inelastic scattering and disappearance reaction has been analyzed as well as status of iron, chrome and nickel.
