THE ANNEALING RECOVERY OF THE PALISADES NUCLEAR POWER PLANT SURVEILLANCE MATERIAL USIHG WELD RRCONSTITUTION

摘要

Palisades Nuclear Power Plant had two of its already tested surveillance capsules used for an annealing recovery study. Previously tested weld metal Charpy specimen halves from Capsules W-290 and W-110, irradiated to fluences of 0.92 × 10~(19) and 1.59 × 10~(19)n/cm~2, respectively, were annealed, weld reconstituted, and tested for annealing recovery evaluation. Transverse plate Charpy halves from Capsule W-290 were also annealed, reconstituted, and tested. The weld material results from Capsule W-290 and W-110 showed measured transition temperature (TT) recoveries of 74% and 77% and upper,shelf energy (USE) recoveries of 61% and 65%, respectively. The transverse plate material results from Capsule W-290 showed a TT recovery of 82% and an USE recovery of 11%. These results are discussed in the following paper.
