Abstract:  
The Laser Peening Program at Curtiss- Wright Surface Technologies (CWST) has contributed to the successful launch of a new manufacturing process for Multi-Purpose Canisters that hold spent nuclear fuel. Their contribution was the result of extensive research, prototype testing, and validation at the CWST facility in Livermore, California on the prevention of Stress Corrosion Cracking (SCC) in the welds of the canisters. The Multi-Purpose Canisters are being laser peened by CWST at the Holtec Manufacturing Division’s Pittsburgh facility.
