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。

Abstract: 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 methods. 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 organizations, allocating collective dose targets, conducting hot spot flushing, developing innovative maintenance tools and techniques, improving maintenance processes, and managing high level radiation areas. These experiences have been validated through practical implementation and proven to be effective.

Key words: nuclear power plant, collective dose, CPR1000 units, outage
