摘要
吊篮是压水堆内的关键设备,吊篮辐板螺栓的缺陷与堆芯安全直接相关。对某核电厂换料大修中发现吊篮辐板螺栓缺陷进行分析,制定了修复方案。修复方案施行结果表明,此项高辐照条件下的水下修复技术方案是可行的。
The core basket is the key equipment in the PWR reactor core, and the defects of the basket former bolts directly related to the core safety. The failure of one nuclear power plant core basket former bolt that happened during the refueling outage is analyzed, and the underwater recovery measures are determined. The implementation result shows that the underwater recovery technique solution is feasible.
