Peening to Fortify Multi-Purpose Canisters Against Stress Corrosion Cracking Enters Production Following Intensive R&D Effort
We are pleased to report that the “peening R&D project” to armor San Onofre’s Multi-Purpose Canisters (MPCs) as part of an overall service life extension program has been successfully completed in collaboration with the Southern California Edison (SCE) company. After extensive prototype testing and validation, the first Canister entered production on August 23rd, marking the historic first for application of peening in the dry storage industry. The NRC has been kept apprised of the process development; the relevant ASME committee has also been briefed. (more…)
