KNOXVILLE, Tenn. -- Sixteen foreign-born construction workers with phony immigration documents were able to enter a nuclear weapons plant in eastern Tennessee because of lax security controls, a federal report said Monday....
...the DOE inspector general's office said in the report issued Monday that its field agents found "official use only" documents "lying unprotected in a construction trailer which was accessed by the foreign construction workers" at the plant.
"Thus, these individuals were afforded opportunities to access ... (this) information," the inspector general wrote. "We concluded that this situation represented a potentially serious access control and security problem."...
The inspector general said it was particularly concerned about allowing subcontractors to self-certify the citizenship of their employees, and that the Office of Counterintelligence didn't know foreign constructions workers were at the Y-12 site until it was notified by the inspector general's office.
