根据核电站设备的使用环境和安全级别要求,设备分为核级和非核级。其中核级产品定义为安全级1E级设备,其基本的要求是保证设备在正常环境下和地震载荷下能够正常运行,并执行其原有的功能。核电厂1E级机柜,是属于保证核电站安全可靠运行的安全级设备。此类设备的作用包括反应堆安全停堆、安全壳隔离、堆芯冷却以及从安全壳和反应堆排出热量,防止放射性物质向环境过量排放等作用。此类设备的设计要求在正常环境和地震载荷下必须能正常运行,保证其原有的性能,完成对各种仪表、电气的供电,信号的连接或扩展。并且还具有对现场工况进行显示和控制等功能。
Equipment according to the use of nuclear power plant safety requirements and levels, equipment is divided into nuclear and non-nuclear level. The nuclear grade product is defined as a safety level 1E equipment, the basic requirement is to ensure that the equipment can work normally and perform its original functions under normal environment and earthquake load. 1E-level nuclear power plant cabinets, is to ensure safe and reliable operation of nuclear power plant safety equipment. The role of such equipment includes the safe shutdown of reactors, containment containment, cooling of the core and the removal of heat from containment and reactors and the prevention of excessive emissions of radioactive material to the environment. The design requirements of such devices must be able to operate normally under normal environmental and seismic loads, to ensure their original performance, to complete a variety of instruments, electrical power supply, signal connection or expansion. And also has the scene conditions for display and control functions.
