Study on Nuclear Safety Management Based on Multiple Nuclear Power Plants Experience Feedback Management

Nuclear power plant experience feedback management includes event reporting, screening, analysis, corrective action management and assessment. In the early stage of nuclear power development in China, experience feedback was conducted based on single nuclear power plants. After years of development, the number of nuclear power plants increases year by year, institutes serving multiple nuclear power plants (multi-plants) develop multi-plants experience feedback management system, to improve event management quality, reduce events recurring probability, promote good practice, carry out experience feedback work effectively, reduce the impact of repeated events, continuously improve nuclear safety quality management level, take the implementation of experience feedback and the assessment of its effectiveness as a priority of nuclear safety management. According to the experience feedback assessment of nuclear safety field - operations personnel management, the vulnerabilities of in nuclear safety management have been identified, including insufficient knowledge and substandard operation by operations personnel, and inadequate monitoring of nuclear safety related equipment by operators. The following measures are recommended: improve the on-the-job training outline of operations personnel, and regularly carry out professional knowledge training of machinery, electrical, instrumentation, etc; formulate a special inspection plan for work standardization, and incorporate the special inspection into the task supervision system for tracking management; establish a tracking process for key equipment defects in nuclear safety issues to ensure the timeliness and effectiveness of tracking nuclear safety issues. This article mainly focuses on multi-plants experience feedback organization, information system, program management and nuclear safety indicators, in order to optimize nuclear safety management and prevent the degradation of nuclear safety level.
