IN WYOMING, BILL GATES MOVES AHEAD WITH NUCLEAR PROJECT AIMED AT REVOLUTIONIZING POWER GENERATION

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 this week 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."
