CEPR多重厂内电源配置与核安全

Configuration and Nuclear Safety of CEPR Multiple On-site Power Supply System

CEPR型压水堆核电厂采用了世界上先进的三代核电技术,其核安全保障特别体现在CEPR的电气系统设计方面。CEPR电源系统配置的多重厂内应急电源,达到了冗余性、多样性和独立性的各项要求,满足纵深防御原则。在核岛安全电源方面,不同层级的应急电源配置足以应对全部的设计基准工况和设计延伸工况,在丧失厂外电源事故情况下的安全分析充分证明了其核安全特性。

Taishan CEPR Nuclear Power Plant implements the world advanced third nuclear power technology. CEPR nuclear safety futures are specially integrated into the design of electrical power supply systems. The multiple on-site power sources configured in CEPR electrical power supply system indicate the characteristics of redundancy, diversity and separation, and satisfy the principle of Defense-in-Depth. In the design of NI safety power supply systems, the emergency power supply in different levels provide enough power supply under all Design Basic Conditions and Design Extension Conditions, for which they are fully demonstrated by the safety analysis under loss of off-site power supply systems.
