One of two nuclear reactors at North Anna Power Station in Louisa County was reconnected to the electric power grid shortly before 10 a.m. Tuesday, according to Dominion Virginia Power.

The power plants’ reactors were tripped offline by a 5.8-magnitude earthquake whose epicenter was 11 miles away in Mineral. The incident marked the first time in the U.S. that a quake had knocked a nuclear plant offline.

After a lengthy series of inspections and public hearings, the Nuclear Regulatory Commission gave Dominion permission to restart the reactors on Friday. Inspections by both Dominion and the NRC concluded that the plant suffered only minor damage from the quake, which did not affect its safety systems.

Dominion officials said Friday it might take 10 days for the plant to return to full operation.
