摘　　要：核电机组大修集体剂量,主要受机组辐射水平和检修总工时影响。本文介绍了核电机组大修集体剂量的控制方法,从完善辐射防护组织、集体剂量目标分解、热点冲洗、创新检修工具、创新检修工艺、高辐射区域管控等方面总结了某核电厂2台CPR1000机组共10次大修集体剂量的控制经验。This article analyzes the two main factors affecting collective dose during outage of nuclear power units-namely the reactor unit radiation levels and the total maintenance working hours-and their control meth-ods.This article summarizes the experience gained from controlling collective dose during ten outages of two CPR1000 units at a particular nuclear power plant.Which includes enhancing radiation protection organiza-tions,allocating collective dose targets,conducting hot spot flushing,developing innovative maintenance tools and techniques,improving maintenance processes,and managing high level radiation areas.These experi-ences have been validated through practical implementation and proven to be effective.
