Turbine likely behind fire at Michigan nuclear plant
The utility says the fire in Unit 1 of the plant in Berrien County's Lake Township began when turbine vibrations caused a generator to leak hydrogen that ignited.

An imbalance from the loss of turbine rotor blades probably caused the vibrations.
It will take one to three weeks to complete turbine inspections, then officials will have a better idea of when they can restart the reactor.
