摘要
射线探伤是各核电厂应用广泛的无损检测手段之一,由于使用的放射源活度较高,若探伤操作或管理不当,可能引发辐射事件或辐射事故。基于“华龙一号”机组设计布局与首修实践,秉持反应堆厂房多源探伤分区管控理念,创新设计“三段式”代码,结合自主研发判定逻辑,保障“华龙一号”机组大修期间反应堆厂房多源探伤安全高效实施,完善国内外辐射防护领域管控体系,为国内外同类型机组提供借鉴与参考。
Radiograph flaw detection is one of the non-destructive testing methods widely used in nuclear power plants.Due to the high activity of the radioactive source to be used,if the inspection operation or management is improper,it may lead to radiation incidents or radiation accidents.This paper,based on HPR1000 unit design layout and first overhaul practice,upholds the reactor building multiple radioactive source of radiograph flaw detection risk control idea,innovatively designed a“three-step”code,combined with the judgment logic of independent research and development,in order to ensure the safe and efficient implementation of multiple radioactive source of radiograph flaw detection in the reactor building during the overhaul of HPR1000 unit.The results could provide support to improve the domestic and foreign control system in the field of radiation protection,and provide experience feedback for the same type of units at home and abroad.
