US seeks faster uranium enrichment expansion to avert supply shortages
LEU•France and the US rely heavily on nuclear power
Nuclear power remains highly divisive. It can produce huge amounts of energy without adding planet-warming carbon emissions to the atmosphere, but it generates difficult-to-manage waste and tends to be extremely expensive.
In Europe, the extreme heat of this summer led to shutdowns because nuclear plants could not be cooled.
France relies on nuclear power for about 70% of its electricity supply, the highest proportion in the world. According to figures from the World Nuclear Association, part of the OECD, the US is the largest producer of nuclear energy, but it only supplies 18% of the country's electricity.
The last commercial nuclear plant to open in the U.S. came online in 2024 and was delayed by years and billions over budget. The U.S. has plans to restart three nuclear plants that had been shut but none of those are online yet.
