核电厂典型放射性热点的管理控制与优化

放射性热点的管理是核电厂辐射防护管理核心项目之一。基于秦二厂多年的实践经验,本文从放射性热点的清单建立、分析和处理制度、协作管控机制等方面进行了阐述,并总结建立了一套有效的压水堆核电厂放射性热点管控优化体系。这套体系在秦二厂进行了应用,有效地提升了电厂对热点的管控能力,降低了热点管控的成本,提高了辐射防护运行业绩。相关方法和措施可为其他核电厂的放射性热点管理提升提供参考。

The management control and optimization of typicalradioactive hotspots in NPP

The management of radioactive hot-spots is one of the core projects of radiation protection management in NPPs.Based on years of practical experience at Qinshan phase Ⅱ,this article elaborates on the establishment of radioactive hot-spots inventory,analysis and processing system,and cooperative management and control mechanisms,and establishes an effective set of control and optimization system for radioactive hot-spots at PWR nuclear power plants.This system was applied in Qinshan phase Ⅱ,which effectively improved the power plant’s ability to control radioactive hot-spots,reduced the cost of hot-spots management,and improved the performance of radiation protection operations.Related methods and measures can provide reference for the improvement of radioactive hot-spots management in other NPPs.
