核保护系统劣化模式下测试设计和分析

单一故障准则是核保护系统设计的基本原则之一,确保保护系统在单一故障下,系统仍然能够实现预期的重要安全功能,确保核安全的实现。本文基于"华龙一号"工程实践,设计劣化模式下测试方案,通过测试分析,验证系统满足单一故障准则和具备冗余功能,满足设计和法规的要求。

Test Design and Analysis in Degraded Modes of The Nuclear Protection System

Single-failure criterion is the basic design principle of nuclear protection system, which ensures that the system can realize the safety function under the single-failure and ensure the nuclear safety. The test approach and test method under degrade-mode are designed based on "HPR1000" first reactor in this paper. Through the test analysis, it is verified that the system meets the single failure criterion, has the redundancy function, and meets the requirements of the design and regulations.
