对反应堆压力容器材料进行辐照监督是保障压力容器在设计寿期内安全运行的一项重要措施。辐照监督管装有压力容器筒体及焊缝材料试样,用于监测压力容器的辐照损伤程度,以指导反应堆压力容器的安全使用,是堆本体重要的核部件。由于运行中堆芯吊篮的紧固件部分脱落需要进行维修。辐照监督管支承、定位结构改造是美国西屋公司承担的秦山核电公司堆芯吊篮修复的组成部分,
Radiation supervision of reactor pressure vessel materials is an important measure to ensure the safe operation of pressure vessels during their design life. The radiation supervision tube is equipped with a sample of pressure vessel barrel and weld material for monitoring the degree of radiation damage to the pressure vessel to guide the safe use of the reactor pressure vessel and is an important nuclear component of the reactor body. Due to the operation of the core basket part of the fastener off need to be repaired. Irradiation supervision tube support, positioning structural transformation is the United States Westinghouse commitment to Qinshan Nuclear Power Company core pile basket repair part,
