"The prospective repository site is located at Yucca Mountain in Nye County, Nevada, approximately 85 airline miles northwest of Las Vegas (Figure 4-1. The site is located on federal land controlled by the Department of Energy (DOE), the Air Force, and the Bureau of Land Management. The land controlled by the DOE is currently part of the Nevada Test Site (NTS). Yucca Mountain lies in a broad range of mountains characterized by sparse vegetation, low precipitation, few population centers, and varied geologic conditions. The geohydrologic system includes both open and closed ground-water basins and a thick unsaturated zone that is thought to have little water movement."
