SCRIBA, NY – This afternoon (June 21), Nine Mile Point experienced a small equipment fire that was in progress for greater than 15 minutes and in accordance with procedures, declared an Unusual Event at 3:05 p.m., according to Jill Lyon, company spokesperson.
The fire was extinguished at 3:08 p.m.
Nine Mile Point exited the Unusual Event at 4 p.m. upon confirmation that fire had been extinguished and completion of area walk downs, she added.
“Our personnel took immediate and appropriate action to extinguish the fire in accordance with our procedures and their training. No personnel were injured as a result of this event,” Lyon said in a prepared statement. “Unit 2 remains in a safe condition and the event did not pose a risk to the public or plant operations. This event did not impact operation of plant systems required for safe operations.”
The fire was on one of the plant’s three feedwater pumps; which provided water to the reactor and in normal operations there are two pumps in service with the third pump available.
Operators took the appropriate action to lower plant power to 62% and remove the affected pump from operation.
At the lower power level, one pump can maintain reactor water level.
The cause of the fire is under investigation.
An Unusual Event is the lowest level of four emergency classification levels for a nuclear plant.

“The event posed no risk to the public or to plant employees. Appropriate officials and personnel were notified,” Lyon noted.
Constellation Energy Nuclear Group will conduct a detailed review of this event to ensure it takes the necessary actions to prevent it from happening again and to apply what they learn from the event to all areas of operation.
