Nuclear power accounts for 19% of electricity generation in the U.S.

This graphic, via Visual Capitalist's Bruno Venditti, illustrates the top sources of enriched uranium for U.S. civilian nuclear power reactors in 2023, based on data from the U.S. Energy Information Administration.

The calculation is based in Separative Work Unit (SWU), a unit that defines the effort required in the uranium enrichment process.

Uranium production in the United States peaked in 1980, while purchases of uranium by U.S. nuclear power plant operators from domestic suppliers peaked in 1981. Since 1992, the majority of uranium purchased by U.S. nuclear power plant operators has been imported.

Currently, the U.S. relies on foreign sources for 71.7% of its enriched uranium, despite possessing domestic resources.

Russia supplies 27.2% of enrichment services, making it the largest single foreign provider for U.S. civilian nuclear power reactors. After Russia, 12% of enriched uranium comes from France, 8% from the Netherlands, and 7% from the United Kingdom.

In November 2024, Russia temporarily restricted enriched uranium exports to the U.S., raising concerns about potential supply risks for utilities operating American reactors. These restrictions were in response to Washington’s recent ban on imports of Russian uranium, which was signed into law earlier this year.

In addition to the U.S., Russia is a major exporter of enriched uranium to countries including China, South Korea, and France.
