NASHVILLE, Tenn. (AP) -- A federal investigation into how Tennessee nuclear weapons plant guards got advance copies of test questions has faulted Department of Energy oversight of private contractors.
DOE inspector general Gregory H. Friedman said in a report issued Wednesday that the questions were widely distributed in August before an upcoming test of guards at the Y-12 plant in Oak Ridge.
The plant came under scrutiny after three protesters spent hours there, defacing the building that houses the nation's store of bomb-grade uranium, before guards responded.
The report says DOE's "eyes on, hands off" approach to contractor management required sending the test to security firm WSI-OR for review and input. It said similar compromises may have occurred at other sites.
The report recommended more oversight, which the DOE said is too costly.
