Less than 5 gallons of oil was spilled into the Ohio River from the Beaver Valley Unit 2 reactor in Pennsylvania.
FirstEnergy Nuclear Operating Co. (FENOC, NYSE: FE) reported to the U.S. Nuclear Regulatory Commission (NRC) that oil was inadvertently pumped from a transformer spill catch area during routine seasonal water removal efforts. Oil was not expected in the spill catch area and it had tested negative for oil during pre-removal testing, the notification said. An oil sheen was detected on the Ohio River immediately surrounding the outfall.
The source of the spill has been terminated, but some residual oil is washing out of the catch basin system into the river. Workers are evaluating containment efforts for the oil in the river and cleanup efforts for the catch basins are currently underway.
