Commercial nuclear reactors all work pretty much the same way. Atoms of a radioactive material split, emitting neutrons. Those bump into other atoms, splitting them and causing them to emit more neutrons, which bump into other atoms, continuing the chain reaction.

Our landmark agreements with Vistra, TerraPower, and Oklo will expand the operation of three nuclear power plants, boost the development of nuclear technology, and foster job growth in American communities.

Companies like Kairos Power are building new types of reactors with the encouragement of the Trump administration, but their success is far from assured.

The agreement will have Meta paying California-based Oklo to provide small nuclear reactors to power data centers in southern Ohio.

China's EAST nuclear fusion reactor has successfully kept plasma stable at extreme densities, passing a major fusion milestone and potentially bringing humanity closer to wielding near-limitless clean energy.

Germany shut its last three nuclear plants in 2023 to favor renewables, which Chancellor Merz called a “serious strategic mistake," on Wednesday. Despite renewables supplying around 65% of domestic energy in 2024, Germany faces declining energy-generation capacity.
