Pages - Home. NNSA/NFO -- Nevada National Security Site. Nevada National Security Site A unique national resource, the Nevada National Security Site is a massive outdoor laboratory and national experimental center that cannot be duplicated. Larger than the state of Rhode Island, approximately 1,375 square miles, the Nevada National Security Site is one of the largest restricted access areas in the United States. The remote site is surrounded by thousands of additional acres of land withdrawn from the public domain for use as a protected wildlife range and for a military gunnery range, creating an unpopulated land area comprising some 5,470 square miles.
Established as the Atomic Energy Commission's on-continent proving ground, the Nevada National Security Site has seen more than four decades of nuclear weapons testing. Larger than many small countries, the Nevada National Security Site offers an enormous amount of space, including more than a 1,000 miles of completely undisturbed land available for new projects.
