A technique was developed to weld end tabs on broken halves of irradiated Charpy impact specimens to produce new specimens. This method was then used to provide additional toughness data for weld metal irradiated in the R. E. Ginna reactor vessel surveillance program. The test results confirmed that the upper-shelf energy of the vessel weld surveillance metal was >68 J (50 ft·lb) as required by 10CFR50, Appendix G.
