Imagine having a event where 95% of the safety systems have been striped away from you? The whole nation is watching the event. You are controlling water level on HPCI. RCIC is dead. You are in a emergency manner repairing the plant so it can be safely cooled down. Then the HPCI lube oil motor catches fire. By itself its a minor event. But on the edge of a meltdown, it is a tremendously restful event.
Hope they have a motor on site. Bet you they are scrambling around begging other utilities to give them a motor. Certainly this motor is no long manufactured. Will they have to reverse engineer it from a two bit contractor?

Dresden operators extinguish small fire on pump
Station declares, then terminates ‘Alert’ classification
MORRIS — Dresden Generation Station operators extinguished a small fire on a pump Monday morning.
The fire lasted three minutes, was contained to the pump and did not affect the safe operation of the plant, according to a news release from the station. Both reactors remain at full power.
Operators promptly identified and extinguished the fire and no off-site assistance was necessary.
An “Alert” was declared and later terminated, as required by the Nuclear Regulatory Commission. An Alert is the second lowest of four emergency classifications established by the NRC. It was declared at 10:50 a.m. and terminated at 1:19 p.m., according to the news release.
