The Nuclear Regulatory Commission has identified chloride-induced stress corrosion cracking (CISCC) of austenitic stainless steel dry cask storage system (DCSS) as an area of great concern. Friction Stir Processing (FSP) was used to repair laboratory- generated SCC cracks in representative stainless steel 304 coupons. Results of this study show the FSW is a viable method for repair and mitigation CISCC cracks. This paper highlights lessons learned and developed techniques relative to FSP development for crack repair in thick section stainless steel 304. These include: development of process parameters, welding at extremely low spindle speed, use of weld power and temperature control and optimization of these controls. NDE and destructive analysis are also presented to demonstrate effectiveness of the developed methods for SCC crack repair.
