Abstract: 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.

Key words: radioactive hot-spot, radiation protection optimization, management control and optimization, standardized management
