Abstract

Abstract

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.
