In the relief request, Exelon proposes to perform a structural weld overlay of the lower cold leg letdown nozzle dissimilar metal welds (DMWs) and Alloy 600 safe-end at Three Mile Island, Unit 1 (TMI-1). The proposed overlay is intended to proactively mitigate the potential for Primary Water Stress Corrosion Cracking degradation, which DMWs have shown a propensity for, in Pressurized Water Reactor (PWR) reactor coolant systems. |
