US nuclear reactor manufacturer Westinghouse is looking to build out the country’s supply chain and secure financing models as part of an $80bn (€69bn) deal struck between the US and Japan in 2025, according to major shareholder Cameco.

Cameco president and chief operating officer Grant Isaac said in an interview with Bloomberg that in nuclear terms things were moving “pretty quickly” following an October 2025 agreement that would see the development of Westinghouse AP1000 and AP300 reactors in the US.

Cameco holds a 49% share in Westinghouse, with the majority 51% stake held by investment management company Brookfield.
