NNSS pin from Las Vegas

NNSS pin from Las Vegas

I obtained this pin at the Atomic Testing Sit Museum in Las Vegas in November, 2013.

The Nevada National Security Site (NNSS) is where the United States carried out most of its explosive tests of nuclear weapons (the vast majority of them underground). When the United States signed the Threshold Test Ban Treaty in 1974, it became the only U.S. nuclear weapons test site. Originally known as the Nevada Proving Grounds, and then as the Nevada Test Site, the facility was renamed in 2010 when its mission was expanded to encompass a broader range of activities related to nuclear weapons, energy, and homeland security needs.

The NNSS is located in the desert, about 75 miles northwest of Las Vegas. The site itself covers more than 1,300 square miles and is surrounded by the federally owned Nevada Test and Training Range that acts as a buffer, giving a total unpopulated area of more than 5,400 square miles—nearly the size of the state of Connecticut. Its remote location and large size were important factors in its selection as a testing site.

Like the other sites in the nuclear weapons complex, the NNSS is overseen by the National Nuclear Security Administration (NNSA), a semi-autonomous agency within the Department of Energy (DOE).
