HISTORY

In 1950, President Truman established what is now known as the Nevada National Security Site (NNSS) to perform nuclear weapons testing activities.  In support of national defense initiatives, a total of 928 atmospheric and underground nuclear weapons tests were conducted at the NNSS between 1951 and 1992, when a moratorium on nuclear testing went into effect. Today, the NNSS is a large, geographically-diverse research, evaluation and development complex that supports homeland security, national defense, and nuclear nonproliferation.

Nye County, Nevada, is the host community of the NNSS, where there are National Nuclear Security Administration (NNSA), Environmental Management (EM), Legacy Management (LM) missions, in addition to the Yucca Mountain Nuclear Waste Repository nearby.
