Operators at the Millstone Power Station in Waterford, CT, partially shut down Unit 2 Thursday after a battery used to power emergency safety equipment was not working.

Shutdown of the plant began at about 8 a.m. as workers simultaneously tried to repair the battery, Millstone spokesman Ken Holt said.

The plant must, under rules required by the Nuclear Regulatory Commission (NRC), shut down whenever the battery is inoperable.

By mid-afternoon, when the unit was at about 20 percent power, crews had bypassed the battery, so the plant could come back up to full power.

As of this morning it was at 99 percent power, Holt said. The battery will end up replaced, he said.
