Earthquake felt at nuclear power plant in New Hampshire

An earthquake felt at the single-unit, 1,295 MWe Seabrook nuclear power plant in New Hampshire led to an unusual event declaration, the U.S. Nuclear Regulatory Commission said.

Workers in the control room said they felt the earthquake around 7:14 p.m. EDT Oct. 16 and confirmed it by calling the dispatch office. A magnitude 4.0 earthquake centered 3 miles west of Hollis Center, Maine occurred around that time. No damages to the plant were discovered during walkdowns.

The plant is currently shut down for a planned refueling outage, and the plant’s seismic monitor is out of service for a scheduled calibration.

The unusual event ended around 1:49 a.m. EDT.
