Abstract

Abstract

In the deep subcritical state, the traditional source multiplication method has the characteristic of low accuracy in the measurement of nuclear reactor reactivity. In order to improve the measurement accuracy, this paper expands CORCA software, develops CORCA-FIX software with fixed source problem solving function and neutron value solving function with discontinuous factor, and uses the comparison program and real reactor data to calculate and verify CORCA-FIX software. The verification results confirm that CORCA-FIX has high accuracy in solving the deep subcritical state of the core with fixed source. After the output results are applied to the real reactor data, better subcritical degree measurement results are obtained, and the deviation criteria of reactivity measurement in engineering applications are met.
