Nevada Test Site

he Nevada Test Site is a United States Department of Energy reservation located in Nye County, Nevada, about 65 miles (105 km) northwest of the City of Las Vegas, near 37°07′N, 116°03′W. Formerly known as the Nevada Proving Ground, the site, established on January 11, 1951 for the testing of nuclear weapons, is composed of approximately 1,350 square miles (3,500 km²) of desert and mountainous terrain. Nuclear testing at the Nevada Test Site began with a one-kiloton (4 terajoule) bomb dropped on Frenchman Flat on January 27, 1951. Many of the iconic images of the nuclear era come from NTS. The BREN Tower, a 465 meter high guyed tower originally for radiation experiments with an unshielded reactor simulating the amounts of radiation received by survivors from Hiroshima and Nagasaki, is located in the NTS at Jackass Flats.
