Description

Neutron spectrum calculations with high accuracy are required for the determination of atomic displacements (DPA) and foil detector reaction rates in the pressure vessel. The influence of cross-section uncertainties including correlations as well as methodical and modelling errors was studied. Calculations were performed for the target quantities DPA and the Fe54 (n,p) reaction rate in a quarter thickness position of the pressure vessels of the 1300 MWel PWR BIBLIS and the smaller 15 MWel BWR VAK. Correlation of transmission and detector cross-sections were taken into account. Additionally the influence of the energy and space dependent source was investigated quantitatively
