ELP反应堆冷却剂泵(RCP)2P-32B 电机定子铁芯压紧失效+压紧指焊缝断裂→对地短路→泵跳闸→反应堆自动跳机
定子铁芯压紧丧失+压紧指焊缝断裂使指片移入接触转子；绝缘损坏对地短路
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.
