摘　　要：压水堆核电站主设备主要包括反应堆压力容器、主管道、蒸汽发生器、稳压器以及主泵泵壳等。压力容器构成了一回路的压力边界,均是质保1级、安全1级、抗震1类的,在高温高压和中子辐照作用下,为了确保主设备能够长期稳定运行,对主设备的材质及其焊接性能要求非常高。根据ASME B&P规范,文章对主设备材质及其焊接性能进行分析和讨论,为我国核电厂主设备的材质选择提供参考作用。The primary equipment in pressurized water reactor includes reactor pressure vessel,reactor coolant piping,steam generator,pressurizer,and reactor coolant pump casing,etc.,which form the pressure boundary of the primary loop.These primary equipment are all pressure vessels of QA Class 1,Safety-related Class 1,and Aseismatic Category 1.Under high temperature,high pressure and neutron irradiation,the requirements for the base material and welding properties of these pressure vessels are very high,so as to ensure the long-term stable operation of a nuclear power plant.The base material and welding properties of these pressure vessels are analyzed and discussed according to ASME B&P Code,which can be as a reference for base material selection of PWR pressure vessels.
