我国已计划在广东省建设核电站,将采用两台90万千瓦级(电功率)的压水堆和两台50赫的汽轮发电机组,还准备在华北、东北等地建设大容量核电站。核电站运行的安全经济性不仅由一回路的设备和装置所决定,并与二回路的设备和装置有很大关系。从过去核电站发生的事故来看,由后者所引起的也很多,如汽轮机掉叶片,低压转子叶轮根部裂纹,汽水分离器漏汽,高、
Our country plans to build a nuclear power plant in Guangdong Province. We will adopt two pressurized water reactors of 900,000 kilowatts (kW) and two 50-herthe turbo-generators. We will also plan to build large-capacity nuclear power stations in northern China and northeast China. The safety and economy of nuclear power plant operations are determined not only by the equipment and installations of the primary circuit but also by the equipment and installations of the secondary circuit. From the past nuclear accident occurred, the latter caused by many, such as turbine blades, low-pressure rotor impeller root crack, steam separator leakage, high,
