Power restored to nuclear plant in Waterford, Connecticut after outage

WATERFORD, Conn. -- Connecticut's nuclear plant in Waterford has restored power, several hours after an electrical short likely caused an outage.

Spokesman Ken Holt said Millstone Power Station was not operating on Sunday, but power had been restored by early afternoon. The plant shut at about 7 a.m. and switched to diesel power.

Neil Sheehan, spokesman for the regulatory agency, says Connecticut Light & Power determined that a short in a power line was the likely culprit.

A spokeswoman says CL&P is investigating and would not confirm the cause of the outage.

The Nuclear Regulatory Commission says automatic trips of the reactors were uncomplicated, safety systems functioned properly and public health and safety are not affected.

The plant is owned by Dominion Resources Inc.

Sheehan says Millstone will have to go through many steps before operations resume.
