On Tuesday, TerraPower, the US-based nuclear power company backed by Bill Gates, announced it has chosen a site for what would be its first reactor. Kemmerer, Wyoming, population roughly 2,500, has been the site of the coal-fired Naughton Power Plant, which is being closed. The TerraPower project will see it replaced by a 345 megawatt reactor that would pioneer a number of technologies that haven’t been commercially deployed before.
These include a reactor design that needs minimal refueling, cooling by liquid sodium, and a molten-salt heat-storage system that will provide the plant with the flexibility needed to integrate better with renewable energy.
While TerraPower is the name clearly attached to the project, plenty of other parties are involved, as well. The company is perhaps best known for being backed by Bill Gates, now chairman of the company board, who has promoted nuclear power as a partial solution for the climate crisis. The company has been selected by the US Department of Energy to build a demonstration reactor, a designation that guarantees at least $180 million toward construction and could see it receive billions of dollars over the next several years.
