Buffett and Gates to Build New Kind of Nuclear Reactor

To be sited in Wyoming, America's largest coal producing state.

Power companies run by billionaire friends Bill Gates and Warren Buffett have chosen Wyoming to launch the first Natrium nuclear reactor project on the site of a retiring coal plant. The reactor is estimated to cost $1 billion.

TerraPower, founded by Gates about 15 years ago, and power company PacifiCorp, owned by Warren Buffett’s Berkshire Hathaway, said that the exact site of the Natrium reactor demonstration plant was expected to be announced by the end of the year.

Small advanced reactors, which run on different fuels to traditional reactors, are regarded by some as a critical carbon-free technology than can supplement intermittent power sources like wind and solar as states strive to cut emissions that cause climate change.

“We think Natrium will be a game-changer for the energy industry,” Gates told a media conference to launch the project in Cheyenne, Wyoming.

“This is our fastest and clearest course to becoming carbon negative,” Wyoming’s governor, Mark Gordon, said. “Nuclear power is clearly a part of my all-of-the-above strategy for energy” in Wyoming, the country’s top coal-producing state.

Late last year the US energy department awarded TerraPower $80m in initial funding to demonstrate Natrium technology, and the department has committed additional funding in coming years subject to congressional appropriations.
