核电厂多样化保护系统设计中验收准则的分析确定

Analysis and Confiring of Acceptance Criteria in Diverse Actuation System Signals Design for Nuclear Power Plants

阐述了核电厂多样化保护系统(DAS)信号设计的流程、方法,对DAS保护信号设置的验收准则的分析确定过程进行了论述,明确了验收准则确定的方法,针对不同工况确定了不同的验收准则。以福建福清核电厂预想事故为实例开展了相关验证,确保了验收准则的有效性与适用性,为后续工作奠定了基础。

This paper introduces the design flow and method of diverse actuation system(DAS) signals, and discusses the process of analyzing and confirming the acceptance criteria for fixing diverse actuation system protecting signal set. The method is clarified, and the acceptance criteria is confirmed for different operation conditions. Besides, the paper illustrates a preconceived accident in Fujian Fuqing Nuclear Power Plant to verify the acceptance criteria suggested, ensuring its validation and applicability, and establishing foundations for the subsequent work.
