核电机组等效强迫停运率,有何意义?有哪些影响因素?
2023年8月29日 · 英文缩写为Equivalent forced outage rate (EFOR)。 如果采用公式表示,会比较直观,它是 机组 设备质量及设备运行可靠性 的重要指标之一。 一般来讲,意外情况越多、非计划停运时间越长,等效强迫停运率就会越高,核电机组等效可用系数和运行质量就会下降。

Utilizing an Equivalent Forced Outage Rate (EFOR) Reliability ...
2013年10月30日 · For years, the unit operated in a load-following mode during the weekdays and at a reduced load at nights and weekends. This new base-load mode had brought forth the management directive for the unit to decrease its Equivalent Forced Outage Rate (EFOR) to improve reliability, bringing forth an improved profit margin.
