Nuclear plant shuts unit 2 days over part failure

Millstone nuclear plant shut 48 hours over failure of equipment moving steam through turbine

WATERFORD, Conn. (AP) -- Connecticut's nuclear plant has shut one of its units for 48 hours due to equipment failure.

Unit 2 of Millstone Power Station was down from Saturday to Monday when a turbine tripped due to a loss of a condenser vacuum. The equipment helps move steam through the turbine, to increase efficiency.

Ken Holt, a spokesman for the Dominion Resources Inc.-owned plant, said a bad relay caused the problem and shut off the pump, which automatically shut down Unit 2. He said the relay was replaced on Monday.

The Nuclear Regulatory Commission said there were no complications following the reactor shutdown.

Last August, Millstone shut Unit 3 automatically when an instrument failure caused a drop in the level of water used to cool the reactor core.
