Abstract

Abstract

In order to verify the new R&D code, a new generation of Pin-by-pin solution package KYLIN V2.0-CORCA-SPn is used to verify and analyze the measured data of the first cycle of Fuqing Unit 5. The results show that the maximum integral rod worth difference is 7.17%, which occurs in N2 rod bank, while the others are lower than 5%. The maximum critical reactivity difference in the cycle is −0.559%. The deviation between fuel pin power and RMC code is within 8%. The numerical model proposed in this paper has high discrete accuracy and good computational stability, and the relevant verification work can provide technical support for the core code design of a new generation of pressurized water reactors, thus meeting the research and development design requirements of new complex reactors.
