AP1000应急运行规程接口分析

Analysis of Interfaces in AP1000 EOP Procedures

AP1000的应急运行规程是基于功能恢复、面向征兆的运行规程。及时执行应急运行规程可以尽可能地避免严重事故发生。但是,应急运行规程的进入接口复杂,且不局限于保护系统内的整定值。通过对AP1000整个运行规程的全面分析,系统总结应急运行规程的所有接口,有助于从总体上把握AP1000停堆和专设安全设施的动作条件,掌握及优化AP1000应急运行规程。

AP1000 Emergency Operation Procedures （EOP） are based on the observed symptoms to recover the safety functions. Performing EOP procedures in time can reduce the severe accident risk as much as possible. However, the EOP entry interfaces are complex, and not limited to setpoints in the protection and safety monitoring system. Analyzing all EOP entry interfaces in AP1000 EOP procedures is very helpful for operators to understand the criteria of safety shutdown and engineered safety features （ESF） actuation, and at same time, it is also helpful for the optimization of EOP procedures.
