"The primary mission of the National Nuclear Security Administration (NNSA) is to maintain the safety, security and effectiveness of the nation's nuclear deterrent through surveillance programs and life extension campaigns. Exercising the skills and capabilities required to accomplish that mission provide the nation with a unique capability to support a wide variety of additional national security missions. To maximize this potential, NNSA is exploring ways to expand the mission of the Nevada Test Site. To reflect this expanded mission, NNSA is renaming the Site the Nevada National Security Site (NNSS). The NNSS will fully utilize the inherent capabilities and remote location of the Site to support all of our Nation's nuclear, energy, and environmental security efforts. The following summary outlines current capabilities and missions at the NTS and highlights possible activities that can be pursued under the new national security mission of NNSS."
