The potential faults occurred in the function design of the process system and in the design, development, verification and validation of the software system used in the Reactor Protection System and Engineered Safety Features(ESF) Actuation System are analyzed. 分析了核电厂系统功能设计、数字化仪表控制系统中软件系统设计、开发、验证与确认中产生潜在的功能缺陷的原因;
The auxiliary power supply of Nuclear Power Station is used to supply the engineered safety features to ensure the safe shutdown of the reactor, when unit trip causes the house supply switch from Main Transformer to it. 核电站的辅助电源系统作为安全电源,在机组故障导致厂用电从主电网切换到辅助电源时向必须运行的专设安全设施(ESF)供电,以保证反应堆安全停堆。
The result of the experiment has shown that the UPS, supplied by the battery, can ensure all engineered safety features to finish their safety function reliably and can supply 20 hours power energy for the demand of the HTR 10 accident supervision and measure. 结果表明,在发生全厂断电的设计基准事故时,由蓄电池组支持的不间断交流电源装置可以可靠地保证各专设安全设施(ESF)完成其安全功能,并能为反应堆事故监测提供20小时的电力供应。
