Reactor pressure vessel(RPV)is the critical and unchangeable component of the PWR during its service lifetime which determines the lifetime of nuclear power plant(NPP).The property decline of RPVis mainly caused by large dose and high energy neutron irradiation during the long term service.Irradiation can reduce the toughness and increase the brittleness of the RPV materials.Thus raising the Reactor pressure vessel (RPV) is the critical and unchangeable component of the PWR during its service lifetime which determines the lifetime of nuclear power plant (NPP).
