Qinshan nuclear power station adopts mature pressurized water reactor, and the nuclear island adopts triple barriers of fuel cladding, pressure shell and containment, which can resist various natural disasters caused by internal pressure, high temperature and extreme accidents. This is the first nuclear power plant built in Chinese mainland. After many expansions, it has developed into a large nuclear power base. This nuclear power plant is the first nuclear power plant researched, designed and built in China. The rated power of the first phase project is 300,000 kilowatts, and the internationally mature pressurized water reactor is adopted. 1965438 broke ground,1910+02+15 years for grid-connected power generation, with a design life of 30 years and a total investment of 6544.
