CEPR状态导向法事故规程自动诊断策略

Automatic Diagnosis Used in CEPR State Oriented Procedures Emergency Operation Procedures

核电厂在进入事故运行规程之前都要进行诊断,由诊断规程引导操纵员进入事故规程。当前,国内现役核电厂均采用人工诊断方式。采用第3代中国先进压水堆(CEPR)的台山核电厂采用最新的技术——自动诊断策略。本文对核电厂处理事故时采用的2种诊断方式进行简单比较,并着重对自动诊断逻辑流程作了详细的介绍,分析核电厂采用自动诊断策略的可行性和优越性。

The diagnosis should be conducted before the nuclear power station enters into emergency operation procedure, and the diagnosis procedure will lead the operators to implement the emergency operation procedure. At present, all the domestic in-service nuclear power stations adopt the manual diagnosis, but for the 3rd generation units CEPR in Taishan nuclear power plant adopts the latest technique – the automatic diagnosis strategy. In this paper, a simple comparison of the two methods adopted for accident treatment in nuclear power stations is included, and the detail presentation about the logical flow of automatic diagnosis is emphasized. Besides, the feasibility and superiority of automatic diagnosis adopted in the nuclear power station is analyzed.
