Bill Gates' Nuclear Power Company Takes Giant Step in Cowboy State

A Wyoming coal power plant will be transformed by a company backed by Microsoft co-founder Bill Gates to run on nuclear power. With the signing of the bipartisan infrastructure act, $1.5 billion will help produce zero-emission power by 2028

"TerraPower, a start-up co-founded by Bill Gates to revolutionize designs for nuclear reactors, has chosen Kemmerer, Wyoming, as the preferred location for its first demonstration reactor," writes Catherine Clifford, a climate and technology reporter for CNBC on Nov. 17. "It aims to build the plant in the frontier-era coal town by 2028."

Once built, the plant will provide a baseload of 345 megawatts, with the potential to expand its capacity to 500 megawatts.

It will cost about $4 billion to build the plant, with half of that money coming from TerraPower and the other half from the U.S. Department of Energy’s Advanced Reactor Demonstration Program.]

Infrastructure Investment and Jobs Act

“Just yesterday, President Biden signed the Bipartisan Infrastructure Deal and today DOE is already putting it to work with more than $1.5 billion heading to Wyoming,” said Secretary of Energy Jennifer M. Granholm in TerraPower's press release on Nov. 16.

"The U.S. Department of Energy is extremely excited about this project and plans to invest nearly $2 billion to support the licensing, construction and demonstration of this first-of-a-kind reactor by 2028," wrote Alice Caponiti, a deputy assistant secretary in the energy department's Office of Nuclear Energy.

Not a conventional nuclear reactor

"The Kemmerer plant will be the first to use an advanced nuclear design called Natrium, developed by TerraPower with GE-Hitachi," adds Clifford.

Natrium plants use liquid sodium as a cooling agent instead of water. Sodium has a higher boiling point and can absorb more heat than water, which means high pressure does not build up inside the reactor, reducing the risk of an explosion.

Natrium plants can also store heat in tanks of molten salt, conserving the energy for later use like a battery and enabling the plant to bump its capacity up from 345 to 500 megawatts for five hours.

In addition to improvements in safety, reduction in costs over conventional nuclear plants, and storing energy, "Natrium plants produce less waste, a problematic and dangerous byproduct of nuclear fission," notes Clifford.

Nuclear demonstration plants headed to Pacific Northwest

"Along with Natrium, two other advanced reactors are also expected to operate in the Northwest region," adds Caponiti with DOE's Office of Nuclear Energy. 

X-energy announced its plans to site its Xe-100 reactor in the state of Washington and NuScale plans to operate its first advanced small modular light water reactor system at Idaho National Laboratory—making this region the new hub of nuclear innovation.

“The Infrastructure Investment and Jobs Act sends a strong message that the U.S. will support the Advanced Reactor Demonstrations to their full and successful completion,” said Darren Gale, X-energy Vice President and ARDP Program Manager, in X-energy's press release on Nov. 15. “This support ensures the success of our reactor and fuel technology at commercial scale”.

Critics get last word

Nuclear power remains controversial within the energy and science communities. Cliffords explored the opposition from the latter in an earlier and more comprehensive piece for CNBC.

On March 18, for instance, the Union of Concerned Scientists (UCS), a non-profit group of 250 scientists and related professionals, issued a 140-page rebuke of “advanced nuclear” reactor designs.

“It doesn’t make sense to us for either government or industry to devote a lot of resources to pursuing high-risk, low-reward technologies – or technologies that could be even worse than what we have now,” Edwin Lyman, Director of Nuclear Power Safety at the Union of Concerned Scientists in Washington, DC, tells CNBC Make It.

Instead, more federal government spending to improve conventional reactors is a better tactic, according to the UCS.
