internals replacement residual stress SCC stress improvement USP
Toshiba have developed a method of reactor internals replacement and also applied some of methods to improve the residual stress for internals that can't be replaced easily. Ultrasonic shot peening (USP) is a stress improvement method that improves the surface residual stress of heat affected zone by using the vibration of Ultrasonic wave. As th e system of USP is simpler and more compact than the other methods, USP is applicable to welds on the bottom of reactor vessel during reactor internals replacemen...
