反应堆保护系统响应时间T2测试方案研究

Research of Test Scenario of T2 Response Time of Reactor Protection System

介绍了反应堆保护系统(RPR)响应时间T2的组成。针对保护通道响应时间T2测试逻辑复杂、大修工期短、测试理论要求高等特点,提出了信号路径全覆盖和卡件全覆盖2种测试方案,并分析比对2种测试方案的优缺点。最后通过对福清核电厂3次大修的实际测试,验证了测试方案的可行性。

The composing of the reactor protection system response time was introduced firstly. Considering the complex and difficulty of the test of RPS response time, and high requirement of test theory, two test schemes of all path converge test and all module converge test were introduced. The advantages and disadvantages of two schemes were analyzed. Through three tests during the outage in Fuqing Nuclear Power Plant. the feasibility of the test was proved.
