核电厂事故保护表设计方法研究

Nuclear Power Plants Fault & Protection Schedule Implementation

事故保护表(Fault&Protection Schedule)是英国核安全审评中的设计金线,其目的在于呈现所有设计基准工况要求的安全功能,完整地展现核电厂设计。基于国际法律法规调研以及华龙一号GDA审查经验,本文对事故保护表的设计方法及其应用进行研究,事故保护表从事故保护需求出发,通过安全功能分解,明确功能要求,并关联到具体实现保护功能的系统、仪控、电气等实体,呈现了事故保护功能的设计链条,同时能够呈现事故保护功能设计的完整性,为核电厂执照申请及审评提供了一种工具参考。

Fault & Protection Schedule presents the golden thread during the Generic Design Assessment(GDA). It clearly shows the safety functions required by design basis conditions and give a visible review of the nuclear power plant. This paper gives a sight on how to produce the Fault & Protection Schedule and discusses its future application on the basis of international codes and standards investigation and personal experience gained from GDA of HPR1000. Fault & Protection Schedule could be a useful tool both for the future licensee and authority party to be generalized in the license application process.
