Control experience on collective dose during outage of CPR1000 unit
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.
