NEUP CINR-18-15261: Friction Stir Based Repair Welding of Dry Storage Canisters and Mitigation Strategies: Effect of Engineered Barrier Layer on Environmental Degradation

The project goal is to apply friction stir based repair and mitigation technique for eliminating failure associated with pitting and stress corrosion cracking in dry storage canisters for spent fuels. Two friction stir based approaches will be pursued in the project: developing a friction stir process envelope, where compressive residual stress development in the weld is promoted; and addition of molybdenum and nitrogen to the SS by friction stir alloying to decrease pitting susceptibility.
