摘要
以美国Point Beach-2 60年延寿执照更新为例,论述基于中子辐照脆化机理的时限老化分析——承压热冲击分析、上平台能量分析和压力-温度限值曲线计算分析;在介绍美国RPV延寿期内辐照监督要求和新技术开发应用的基础上,参照法国核电法规要求,重点分析了中国在RPV中子辐照脆化评估中的几个关键问题。
Taking the 60 years life extension license of Point Beach -2 as an example, the time limited aging analysis (TLAA) based on neutron irradiation embrittlement mechanism was discoursed, including pressure thermal shock (PTS) analysis, upper shelf energy (USE) analysis, and pressure - temperature limited curve (P - T curve) calculation. Based on the introduction of irradiation surveillance require- ments for life extension of RPV and development and application of the new technologies in USA, accord- ing to the requirements of France nuclear power codes, several key issues concerning the neutron embrit- tlement assessment of RPV in China was focused on analysis.
