HARTFORD, Conn. (AP) -- Connecticut's nuclear power plant has shut down one of two units because seawater used to cool the plant is too warm.
The Nuclear Regulatory Commission and Millstone Power Station in Waterford said Monday that the plant's unit 2 shut down Sunday.
The water is supposed to be no hotter than 75 degrees. It has been averaging 1.7 degrees hotter than the limit following the hottest July on record.
The federal agency issued an emergency license amendment last week, allowing Millstone, a subsidiary of Richmond, Va.-based Dominion Resources Inc., to use an average temperature of several readings.
Even with that, the water was too hot for the plant's operations.
Millstone spokesman Ken Holt says Dominion does not have an estimate of when unit 2 will restart.
