Bill Gates and his energy company are starting construction at their Wyoming site for a next-generation nuclear power plant he believes will “revolutionize” how power is generated.
Gates was in the tiny community of Kemmerer Monday to break ground on the project. The co-founder of Microsoft is chairman of TerraPower. The company applied to the Nuclear Regulatory Commission in March for a construction permit for an advanced nuclear reactor that uses sodium, not water, for cooling. If approved, it would operate as a commercial nuclear power plant.
The site is adjacent to PacifiCorp’s Naughton Power Plant, which will stop burning coal in 2026 and natural gas a decade later, the utility said. Nuclear reactors operate without emitting planet-warming greenhouse gases. PacifiCorp plans to get carbon-free power from the reactor and says it is weighing how much nuclear to include in its long-range planning.
The work begun Monday is aimed at having the site ready so TerraPower can build the reactor as quickly as possible if its permit is approved. Russia is at the forefront for developing sodium-cooled reactors.
Gates told the audience at the groundbreaking that they were “standing on what will soon be the bedrock of America’s energy future.”
“This is a big step toward safe, abundant, zero-carbon energy,” Gates said. “And it’s important for the future of this country that projects like this succeed.”
Advanced reactors typically use a coolant other than water and operate at lower pressures and higher temperatures. Such technology has been around for decades, but the United States has continued to build large, conventional water-cooled reactors as commercial power plants. The Wyoming project is the first time in about four decades that a company has tried to get an advanced reactor up and running as a commercial power plant in the United States, according to the NRC.
It’s time to move to advanced nuclear technology that uses the latest computer modeling and physics for a simpler plant design that’s cheaper, even safer and more efficient, said Chris Levesque, the company’s president and chief executive officer.
TerraPower’s Natrium reactor demonstration project is a sodium-cooled fast reactor design with a molten salt energy storage system.
“The industry’s character hasn’t been to innovate. It’s kind of been to repeat past performance, you know, not to move forward with new technology. And that was good for reliability,” Levesque said in an interview. “But the electricity demands we’re seeing in the coming decades, and also to correct the cost issues with today’s nuclear and nuclear energy, we at TerraPower and our founders really felt it’s time to innovate.”
