摘要
介绍了某核电站1号机组首次大修期间不同工作岗位通用服务人员集体剂量分布,分析剂量来源及产生的原因,提出了相应的改进措施,并将改进措施应用到该核电站2号机组首次大修中,通过两次大修人员集体剂量比对,验证改进措施的可执行性,最终达到降低人员剂量的目的。
The colletive dose distribution of general service personnel in different positions during the first overhaul of Unit 1 in some NPP is presented. The sources and causes of dose are analyzed. Some improvement measures for optimization are proposed correspondingly, which's then been applied to the first overhaul of Unit 2. The implementation of these measures has been verified by overhaul personnel dose comparison of both units. And the goal of reducing personnel dose is ultimately achieved.
