OAK RIDGE, Tenn. – An urgent review of computer security at Oak Ridge National Laboratory (search) turned up no missing classified items, officials said.
Energy Secretary Spencer Abraham ordered an inventory of "classified removable electronic media" at all Department of Energy (search) facilities last month after two disks of secret data were reported missing at Los Alamos National Laboratory (search) in New Mexico.
The review included the Y-12 nuclear weapons plant at Oak Ridge, which has now resumed normal operations, The Knoxville News Sentinel reported for Thursday editions.
Walter Perry, a DOE spokesman, said an inventory at Oak Ridge facilities found no missing computer disks or other media covered in the inventory.
Perry said the laboratory was among the first to be cleared by the DOE to restart classified operations, getting the go-ahead Aug. 11. The Y-12 warhead-production center received clearance the next day.
The weapons plant had been converting its computer operations to diskless work stations even before the latest DOE security problem.
Other reviews at the Oak Ridge complex should be completed in the next few days, Perry said.
The DOE has said new training programs and protocols will be set up to ensure strict accountability for all classified information.
