Y-12 began planning their new Highly Enriched Uranium Materials Facility in 1998.
The federal government is taking unprecedented action after three demonstrators penetrated a secure area at the Y-12 National Security Complex in Oak Ridge.
According to a press release from the U.S. Department of Energy, B&W Y-12, LLC, management and operating contractor for Y-12, has ordered a temporary security stand down at the facility, while all security measures are reviewed.
The stand down period is effective today (Wednesday) and is expected to end next week. During that time, all special nuclear materials will be moved to vault-type facilities on site, all nuclear operations will be halted, and contractor security personnel will undergo training and refresher instruction.
The release says "this is being done to address additional security training and execution deficiencies identified by the contractor after Saturday's incident. However, all nuclear materials at Y-12 are in safe, secure storage and we remain entirely confident in the security of Y-12's facilities."
The National Nuclear Security Administration fully supports this step which is necessary to ensure continued confidence in safe and secure operations at Y-12, according to the release.
