Strategies of Factory Tests of Safety Digital Instrumentation and Control System in Nuclear Power Plants
-
摘要: 结合国内安全级数字仪控系统(DCS)工厂测试(FT)实践及核安全审评经验,根据核安全法规和相关标准对安全级DCS进行阶段划分研究分析。结果表明,核电厂安全级DCS应尽量进行完整功能和性能测试,谨慎选择试策略(FOAK)测试策略,对于首台机组建议不采用FOAK测试策略。Abstract: Combining the domestic practice and the experiences in the nuclear safety review of the factory tests（FT） of the safety digital instrument and control system（DCS）, DCS FT is identified as several stages according to nuclear safety regulations and standards. The results show that the safety DCS function and performance should be tested. FOAK test strategy should be used discreetly, and not suggested to be used for the first system.
