红沿河核电厂反应堆保护系统定期试验方案设计

Design of Periodic Test for Reactor Protection System of Hongyanhe NPP

红沿河核电厂反应堆保护系统采用三菱的MELTAC安全级数字化仪控平台。在简介红沿河核电厂反应堆保护系统定期试验范围和原理的基础上,详细描述核电厂反应堆保护系统定期试验中的测量仪表通道试验、保护逻辑试验和输出信号及相关驱动器试验的设计方案,并对其特点进行分析。结果表明,红沿河核电厂反应堆保护系统定期试验实施方案充分利用了自动试验装置所带来的优势,扩大检测范围,在有效性、灵活性及便利性方面均有显著提高。

Reactor protection system of Hongyanhe project is based on Mitsubishi MELTAC safety digital platform. This paper introduces the scope and principle for periodic tests of reactor protection system, and then it describes the design schemes of instrumentation channel test, protection logic test and actuator control channel tests in detail, finally it analyzes the characteristics of the tests. The result shows that the periodic test solutions of reactor protection system for Hongyanhe project adequately utilize the advantages of automatic tester, and the test scope is extended and the test availability, flexibility and facility are enhanced.
