反应堆保护系统T3试验工厂测试方案研究

Research on Factory Test Scheme of T3 Test for Reactor Protection System

国内正在建设和规划的核电机组的反应堆保护系统均采用数字化的安全级DCS系统。目前的安全级DCS系统已具备比较强的系统自检能力,可以自行探测系统的部分运行异常,但是保护系统仍需执行定期的试验,以全面探测整个反应堆保护系统及其接口设备可能存在的问题。其中,T3试验就是验证保护体系处理后的输出信号、相关接口设备以及驱动设备的功能完整性。由于保护系统的接口系统众多,而在保护系统的工厂测试阶段往往不具备系统联调的条件,T3试验功能验证可能不彻底。本文研究一种在工厂测试阶段针对T3试验的测试方案,用于基于中国核动力研究设计院研发的核电厂安全级DCS平台(NASPIC)的某反应堆保护系统,以实现在工厂测试阶段对T3试验功能的完整验证。

The reactor protection system of nuclear power plant under construction and planned in China are all using DCS system. The current DCS system already has a system Self-Diagnostics capability, can detect part of the system’ s operation abnormally, but protection system still needs to perform periodic-test. The T3 test is to verify the functional integrity of the output signal, interface equipment after the protection system processed. Due to the large number of interface systems and equipments of the protection system, the conditions for T3 test are not available at the factory test, T3 test function verification may not be complete. This paper research on a Factory Test Scheme of T3 Test, used in RPS system which based on NASPIC （ Nuclear Ad-vanced Safety Platform of I＆G ） . This scheme can realize complete verification of the T3 test in the factory test stage.
