摘要
Abstract
To address the difficulty in fully and accurately considering the impact of local thermal transients on the fatigue life of primary loop pressure boundary pipelines during the design stage of pressurized water reactor nuclear power plants,the thermal fatigue mechanism and thermal fatigue damage evaluation methods of primary loop pressure boundary pipelines were investigated through analysis of the latest domestic and international research findings.Meanwhile,the development and application of online monitoring systems at home and abroad were comparatively analyzed,and the functions,related parameters,and differences among the fatigue monitoring systems of major domestic pressurized water reactor nuclear power plants were compared.The research results show that a domestically developed system has a well-configured fatigue analysis module that fully considers environmental impact factors and has field application experience,which can provide effective support for thermal fatigue assessment.This study can provide reference and guidance for the further development of thermal fatigue monitoring systems for pressurized water reactor nuclear power plants.关键词
