Gates's TerraPower Reactor Is Delayed Two Years After Russia's War Cuts Off Its Fuel
[RECORD.TXT] · cat --full
In December 2022, TerraPower — the advanced-nuclear company Bill Gates founded and chairs — announced that its first Natrium demonstration reactor in Kemmerer, Wyoming would be delayed by at least two years. The reason: the only commercial source of the specialized HALEU (high-assay, low-enriched uranium) fuel the reactor needs was Russia, and Russia's invasion of Ukraine had cut off that supply. The setback underscored both the West's dependence on Russian nuclear fuel and the practical hurdles facing Gates's bet on next-generation nuclear power.

Gates-Backed Commonwealth Fusion Installs Its First Magnet, Racing Toward 2026 'First Plasma'
Commonwealth Fusion Systems — backed by Bill Gates's Breakthrough Energy — hit a major hardware milestone heading into 2026, installing the first of 18 powerful high-temperature superconducting magnets in its SPARC tokamak near Boston. CFS is racing to achieve 'first plasma' in 2026 and net energy gain in 2027, aiming to prove that commercial fusion power is possible. It is among several fusion ventures Gates has funded in his long search for an 'energy miracle' to fight climate change.

TerraPower Begins Building America's First Utility-Scale Advanced Reactor in Wyoming
On April 23, 2026, Bill Gates's nuclear company TerraPower formally began nuclear construction of its first Natrium reactor in Kemmerer, Wyoming — billed as the first utility-scale advanced nuclear power plant built in the United States. The milestone followed the Nuclear Regulatory Commission's approval of the construction permit, and came after earlier work on non-nuclear facilities and a multi-year delay caused by the loss of Russian fuel supplies. The 345-megawatt sodium-cooled reactor, with molten-salt energy storage, is central to Gates's bet that next-generation nuclear can deliver clean, around-the-clock power.
