Boiling Water Reactor Fracture toughness Pressurized Thermal Shock Reactor Pressure Vessel Stress intensity factor Structural integrity Transient condition
The structural integrity for Pressurized Thermal Shock (PTS) was evaluated for the RPVs of Japanese Boiling Water Reactors (BWRs). It has been clarified that the BWR RPVs have the sufficient margin of fracture toughness by calculating the stress intensity factor in transitional condition and the acceptance criteria for RPV shell plate which is assumed to be neutron-irradiated in core region for 60 years. ...

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...
