AP1000 is the 3rd generation nuclear power plant imported from Westinghouse.It takes full advantage of passive techniques on the basis of safety coefficient enhancement,and it cancels the nuclear-grade active devices such as emergency diesel generator,decreases the operations by operators,and therefore decreases the human factor influences.It uses the minimum systems and equipment.and therefore simplifies the configuration.It adopts the advanced equipment that with long maintenance cycle or maintenance free,it decreases the interfaces of systems and equipment,enhances the safety response ability of the power plant to serious accidents or natural disasters.The RCP system is a key item for importing this technology due to its importance and particularity.It's to understand the configuration and special structure of the electric equipment by analyzing the function of RCP and the principle of electric system.
