Unit 2 of the Brunswick nuclear power plant in North Carolina experienced an apparent fire on July 12, according to a report filed with the Nuclear Regulatory Commission (NRC).
The Brunswick 2 unit, which is operated by a Duke Energy (NYSE:DUK) subsidiary, was listed at 76% power early July 13.
This is the way the situation was described in the event report filed with NRC:
“At approximately 2039 EDT, there was smoke in the Service Water Building with the trip of the 2C service water pump. In accordance with plant procedures, unit-2 was ramped down to 70 percent power and the “Alert” was declared. EAL (emergency action level) SA8.1 was entered for damage with degraded performance including visible damage to the service water pump. Service water pressure was eventually restored by running both the 2A and 2B service water pumps.”
The nuclear unit exited the “alert” status about 40 minutes later because service water pressure had been restored, according to the NRC event report.
Brunswick Units 1 and 2 are 1970s vintage boiling water reactors (BWRs) located in Southport, North Carolina. Each unit has a generating capacity of more than 900 MW. During 2014, the Brunswick station had a capacity factor of more than 87%, according to GenerationHub data.
