The US site considered for the nation's first permanent repository for nuclear waste is located in:

Yucca Mountain, Nevada, has been designated as the site for the United States' first permanent repository for high-level nuclear waste. This designation stems from extensive studies and evaluations conducted by the U.S. Department of Energy, which determined that Yucca Mountain's geological and hydrological features make it a suitable location for isolating nuclear waste from the environment. The mountain's remote location and its ability to provide a barrier against the possible migration of contaminants contribute to its selection.

The site has undergone rigorous scientific assessments over the years to ensure safety and security, with considerations for how it will contain the radioactive waste over millennia. Although there has been political and public debate regarding its suitability and the transport of waste to the site, Yucca Mountain remains the focus of federal plans for managing the nation's nuclear waste effectively.
