Oyster Creek at Full Power After Weather-Related Event

Jan 08, 2018

Low water levels at the Oyster Creek Nuclear Generating Station due to frigid temperatures prompted plant operators to declare an Unusual Event at about 5:25 a.m., Jan. 6, according to the Nuclear Regulatory Commission. An Unusual Event is the lowest of four levels of emergency classification used by the NRC. The event was terminated at roughly 11 p.m. Jan. 7 after water intake levels were determined to be at acceptable levels.

The plant uses water from its intake canal for cooling purposes, including in its condenser. That water, which does not flow through any systems containing radioactive liquids, is then discharged at a higher temperature to the outfall portion of the canal.

“Control room operators reduced reactor power to about 70 percent in response to the lower-than-normal water intake levels,” Neil Sheehan, public information officer for NRC Region 1, said. “The NRC resident inspectors assigned to Oyster Creek on a full-time basis responded to the site to independently verify that the plant was in a safe condition. NRC resident inspectors are continuing to follow up on the event.” —G.G.S.
