WATERFORD, Conn. (AP) — Federal officials say Connecticut’s nuclear plant has lost electricity and has switched to emergency diesel generators.
The Nuclear Regulatory Commission says the two reactors at Millstone Power Station in Waterford shut down at about 7 a.m. Sunday.
The agency says the automatic trips of the reactors were uncomplicated, safety systems functioned properly and public health and safety are not affected.
Diesel generators at the plant, which is owned by Dominion Resources Inc., activated and are providing power to safety systems until off-site power is restored.
Federal officials say the cause of the off-site power outage is not known. However, the agency says preliminary indications are that the problem began in the plant’s switchyard that holds electrical components.
A spokesman for Millstone did not immediately respond to an email seeking comment.
