Bill Gates, Warren Buffett building nuclear reactor in coal-rich Wyoming

Billionaire buddies Bill Gates and Warren Buffett are teaming up to build a nuclear reactor — on the site of a coal plant that’s being phased out in Wyoming.

Nuclear reactor design company TerraPower, which Gates founded about 15 years ago, and power company PacifiCorp, which is owned by Buffett’s Berkshire Hathaway, are partners on the Natrium nuclear reactor pilot project, the companies said.

The Department of Energy is also involved in the project through funding and a cooperative agreement.

TerraPower claims its Natrium reactor, which was designed in partnership with GE Hitachi Nuclear Energy, is more fuel-efficient, cost-effective and safer than traditional nuclear reactors, Gates said by video earlier this week at a news conference in the state capital, Cheyenne.

“We think Natrium will be a game-changer for the energy industry,” said Gates, who’s going through a high-profile divorce. He appeared to be wearing his wedding ring in the video.

“Wyoming has been a leader in energy for over a century and we hope our investment in Natrium will help Wyoming to stay in the lead for many decades to come,” he added.

But some scientists have expressed concern that there’s little evidence that advanced nuclear reactors are safer than traditional ones.

A recent report from the Union of Concerned Scientists noted that the supply chain for advanced reactors could be a target for terrorists looking to create a crude nuclear weapon. “In fact, certain alternative reactor designs pose even more safety, proliferation, and environmental risks than the current fleet,” the report states.

The specialized storage technology of the Natrium system can boost its output to the amount of energy required to power about 400,000 homes, TerraPower said.
