TOKYO: Mitsubishi Heavy Industries and the Japan Atomic Energy Agency have signed an agreement to participate in a next-generation nuclear energy project with TerraPower, a company started by Bill Gates.

The memorandum of understanding calls for cooperation in developing advanced nuclear technologies, Mitsubishi Heavy said Thursday.

Located in Kemmerer, in western Wyoming’s desert highlands, the demonstration project will use a nontraditional, sodium-cooled nuclear reactor. It will hire workers from a local coal-fired power plant scheduled to close soon.

MHI, one of Japan’s largest industrial conglomerates, said it will explore ways to provide technical support and to develop the reactor.

“MHI will also bring back expertise and knowledge obtained through this partnership to contribute to the advancement of nuclear innovation in Japan,” the company said in a statement.

It said the company views nuclear energy as essential for achieving net zero carbon emissions to counter climate change.

TerraPower plans to make its plant useful for today’s energy grid of growing renewable power. A salt heat “battery” will allow the plant to ramp up electricity production on demand, offsetting dips in electricity when the wind isn’t blowing and sun isn’t shining.

The approach isn’t new. Russia has had a commercial sodium-cooled reactor in use at full capacity since 2016 and such designs have been tested elsewhere in the U.S.

Gates, the famous co-founder Microsoft, started Bellevue, Washington-based TerraPower in 2008 and is chairman of its board.
