(Reuters) The government's "Fort Knox" of weapons-grade uranium storage has ended a contract with a unit of an international security firm two months after an 82-year-old nun and other nuclear activists broke into the site.
The managing contractor at the Oak Ridge, Tennessee, site, B&W Y-12, a unit of Babcock & Wilcox Co, said late on Friday it will terminate the contract with WSI Oak Ridge on October 1. WSI is owned by security firm G4S, which was at the center of a dispute over security at this year's London Olympic Games.
The move came after the National Nuclear Security Administration (NNSA), an Energy Department agency, sent a letter on Friday to B&W Y-12 President Charles Spencer saying it had "grave concerns" about his company and WSI providing security at Y-12, the nation's only site for storing and processing weapons-grade uranium.

The letter recommended that B&W terminate the subcontract with WSI and work with it to take over security operations after the July 28 break-in.
