BEAVER, PA.: Officials say a small patch of degradation has been found on the inside wall of the containment building surrounding a western Pennsylvania nuclear plant.
FirstEnergy Corp. says the discovery was made at Beaver Valley Nuclear Power Station’s Unit 1, which was shut down at the end of last month for scheduled refueling.
Company spokeswoman Jennifer Young says the degradation was probably caused by decay of a piece of wood touching the steel liner of the 4.5-foot-thick concrete wall.
The Akron-based company plans a more extensive inspection to resolve the issue. The Federal Nuclear Regulatory Commission is also investigating.
Young said a similar area of corrosion found in 2009 was replaced with a new section of steel and has had no further problems.
Young says, “Public health and safety isn’t impacted.”
