摘　　要：拒动率测试是验证核电厂反应堆保护系统(RPS)拒动率指标的有效手段,但是拒动率测试要求的测试次数庞大,采用人工测试的手段,存在执行效率低、耗费周期过长不可执行的问题。为此,本文针对拒动率指标测试要求,提出了一种采用测试装置开展自动测试的方案,通过拒动率测试需求分析及自动测试装置设计,建立并实现了拒动率自动测试系统,并基于ACPR1000 RPS系统对拒动率自动测试进行实践。实践表明,本文提出和建立的自动测试方案能有效完成拒动率指标的测试要求,大大节约了测试资源和成本,具有较大应用价值。Rejection rate is an important specification of nuclear power plant(NPP) reactor protection system(RPS), but the number of tests required is huge. If manual testing is used, there will be matters of low execution efficiency, long cycle and unenforceability.In this paper, a scheme of automatic test by test device is proposed.Through analysis of the test requirement of the rejection rate of RPS and the design of automatic test device, the automatic test system of rejection rate is established and realized. Based on RPS system, the automatic test system of rejection rate is practiced.Practice shows that the automatic test scheme proposed and established in this paper can effectively fulfill the test requirements of rejection rate, greatly save testing resources and costs. It has great application value.
