Overview
- Constellation plans to restart Three Mile Island Unit 1 by the end of 2027, backed by a $1 billion Department of Energy loan guarantee and a 20-year power deal with Microsoft.
- Following its early‑2026 purchase of Calpine, Constellation reports nearly 60 gigawatts of zero‑ and low‑emission capacity across nuclear, natural gas, and renewables.
- President Trump set a goal to expand U.S. nuclear capacity to 400 gigawatts by 2050, while the Energy Department aims to triple U.S. nuclear output by mid‑century.
- The World Nuclear Association counts 75 reactors under construction and 120 more planned worldwide, pointing to a broad global buildout.
- Fuel supply remains pivotal as Cameco produced about 15% of the world’s uranium in 2025 and operates the high‑grade McArthur River/Key Lake and Cigar Lake mines.
