The United States imports the vast majority of the uranium utilized by its commercial nuclear power reactor fleet, since domestic mining operations supply only a tiny fraction of total annual requirements. According to data compiled by the U.S. Energy Information Administration, the nation relies heavily on foreign supplier countries, importing significant percentages from international allies and resource-rich nations such as Canada, Kazakhstan, Uzbekistan, Australia, and historically Russia. Following recent legislative bans and strict import limitations targeting Russian nuclear fuel components to enhance national energy security, domestic nuclear utilities have increasingly pivoted toward expanding long-term supply contracts with producers based in North America, Central Asia, and Australia.
