Abstract

Abstract

The ¹⁰B abundance evolution under two conditions,i.e.,with and without boronizing,is calculated and analyzed with theoretic derivation method,and the evolution pattern of ¹⁰B abundance for one cycle in PWR is provided.The comparison of the calculated and measured ¹⁰B abundance shows that the abundance equation considering the boronizing is accurate.With this,the theoretical boron concentration provided by the fuel management software can be corrected and validated.According to the equation and analysis method,the boron concentration deviation problem could be well understood or even solved.
