An Arizona businessman pleaded guilty to federal charges that he lied about a part used at Peach Bottom Atomic Power Station.

Kevin A. Doyle, 47, of Scottsdale, Ariz., pleaded guilty to material false statements in federal district court in Phoenix on Nov. 30, federal officials announced Wednesday.

When Pentas Controls was unable to repair a nuclear measurements display for the Peach Bottom station, Doyle had a substitute display from the Brunswick Nuclear Plant in North Carolina shipped from his Scottsdale facility, according to a news release from U.S. District Attorney John S. Leonardo.

Pentas Controls is owned by Doyle and is a vendor for nuclear power plants.

Prior to its shipment, a Pentas Controls employee filed down the serial number on the display to conceal its identity, in violation of Nuclear Regulatory Commission safety regulations, the release says.

On March 15, 2011, Doyle lied to Nuclear Regulatory Commission-Office of Investigations officials by repeatedly denying that the un-repairable display had been substituted with a working one, the release says.

Doyle faces a maximum penalty of 5 years in federal prison, a $250,000 fine, or both. He will be sentenced on Feb. 11.
