Abstract:
This paper describes the effects of residual stress improvement by water jet peening, which is expected to improve the residual stress on various component surfaces in
nuclear power plants as a preventative maintenance technique foar preventing stress corrosion cracking and fatigue fracturing. Numerical analysis is performed to clarify
the fundamental mechanism of residual stress improvement, and various tests are done to determine the fundamental characteristics of and suitable conditions for the residual
stress improvement. Fundamental tests confirm the applicablility of the water jet peening technique for necluear power plants that can improve residual stress.
