Surry Unit 2 nuclear reactor shuts down due to coolant problems

By Dorothy Davis

According to a filing with the Nuclear Regulatory Commission (NRC), Dominion’s Surry nuclear power station’s Unit 2 automatically shut down Wednesday due to coolant problems.

Plant officials advised the NRC that the loss of RCS coolant flow in one loop resulted in the automatic trip of the Unit 2 reactor at approximately 5:33 a.m. EST. Systems responded as expected and there was no release of radiation.

The Surry nuclear power station’s Unit 1 reactor was not affected by the event and continues to operate at 100 percent capacity.

Dominion said an estimated time for repair and restart is not known.

The Surry nuclear power station located in southeastern Virginia, generates approximately 1,598 megawatts of power from its two triple-loop Westinghouse pressurized water reactors – enough electricity to power 400,000 homes.
