AIKEN, S.C. (AP) -- Officials at the Savannah River Site say an employee improperly accessed the personal information of thousands of workers.
The Aiken Standard reports that manager David Moody said in an email to employees this week that the information was not ever "improperly distributed" or accessed by a hacker outside SRS.
In March, the U.S. Department of Energy said its inspector general was investigating a security breach that had compromised personal information of at least 12,000 workers at the site near Aiken. Officials said no classified data was part of the information accessed.
The 310-square-mile Savannah River Site once produced plutonium and tritium for atomic bombs. Work there is now focused mostly on research and cleaning up contaminated areas.
