BOSTON (Reuters) - Smoke billowing from an equipment elevator at a New Hampshire nuclear plant briefly triggered an "unusual event" on Monday but did not impact operations or affect any employees, officials said.
Smoke was detected in a transformer attached to a service elevator in a support building at Seabrook Station in Seabrook, said Jim Van Dongen, spokesman for the state's department of safety.
The plant's own fire brigade addressed the "unusual event," the lowest of four emergency classifications for a nuclear plant, he said.
There were no injuries, no evacuation and no impact to ongoing operations, officials said.
Van Dongen said only two or three such "unusual events" have been reported since the plant began operating in 1990.
Seabrook Station is owned and operated by a subsidiary of NextEra Energy Resources and is situated on 900 acres near the southern New Hampshire coast, about 40 miles north of Boston.
