摘要
Abstract
The safety classification of nuclear power plant items is the basis for balancing safety and economy.Appropriate safety classification ensures that items have suitable quality to achieve safety functions,while avoiding excessive conservatism.At present,the safety classification methods used in large pressurized water reactor nuclear power plants are different,and some system equipment functions have changed,resulting in differences in the final safety classification results of system equipment.This article analyzes and discusses the differences in safety classification of some system equipment in large pressurized water reactor nuclear power plants,and provides relevant classification suggestions and insights.An analysis and explanation of the reasons for differences in Reactor Coolant Pressure Boundary(RCPB),accumulator systems,and equipment classification for containing small quantities of radioactive fluid is provided.Recommendations and insights are also offered for the classification of equipment containing small quantities of radioactive fluid where clear criteria and methods are lacking.关键词
