Abstract

Adjustment of the neutron fluence on the VVER-440 reactor pressure vessel (RPV) inner wall has been carried out. For the purpose of this adjustment the neutron flux responses' sensitivity to the main parameters of calculation uncertainty has been calculated. The obtained sensitivities, the parameters uncertainty, and activity measurement data of iron, copper, and niobium detectors positioned behind the RPV of Kozloduy NPP Unit 1 have been used in this adjustment.
