ELP一台 RCP 因电气故障跳闸→反应堆跳机；随后发现同泵 ¾ 英寸管道反应堆压力边界泄漏
RCP 电气故障；¾ 英寸管道焊接/材料相关反应堆压力边界泄漏
The recorded code ELP is an ISO 14224:2016 functional failure code (describes what the equipment failed to do). The damage mechanism (how it failed) is shown in the Mapping block above. The two are distinct dimensions in ISO 14224.
