Since 2006, the National Nuclear Security Administration, or NNSA, a semi-autonomous agency within the U.S. Department of Energy, had begun to develop a plan to consolidate high-security special nuclear materials.
The NNSA issued an environmental analysis in 2008 that allowed for the removal of Category I/II special nuclear material items by the end of the 2012 fiscal year.
The removal and consolidation of the materials was completed on schedule, according to the NNSA.
