Discussion about Integrity Issue of Reactor Pressure Vessel in Nuclear Power Plant

Nuclear reactor pressure vessel( RPV) is one of the critical equipments for a nuclear power plant,and its integrity will impact the safe operation of the nuclear power plant. To ensure the integrity of the reactor pressure vessel,safety concern is highlighted in design,manufacture,installation and operation phase. It provided a reference for the nuclear power plant reactor pressure vessel in design,manufacture, installation,operation and maintenance phase by introducing the material development of reactor pressure vessel,typical degradation model of reactor pressure vessel,and analyzing reasons for the degradation and proposing relevant measures to ensure the integrity of RPV.
