US approves construction of Gates-backed TerraPower nuclear reactor in Wyoming

The U.S. Nuclear Regulatory Commission announced on Wednesday that it has approved the construction of a small nuclear reactor in Wyoming, backed by Bill Gates.

TerraPower's 345 megawatt sodium-cooled Kemmerer reactor was approved by the Nuclear Regulatory Commission, marking the first commercial reactor approval in almost a decade. The reactor is to be constructed near a coal-fired power plant, and will become operational in the early 2030s.

TerraPower announced in a press release that it will begin construction within the next few weeks.

The NRC stated that the plant includes a system of energy storage to temporarily boost output up to 500 MW.

The NRC completed its technical review of the design in less that 18 months.

Last year, President Donald Trump issued executive orders to speed up the permitting process by the NRC. He wanted to reduce a multi-year permit process to just 18 months.

TerraPower's Natrium nuclear reactor would use a fuel known as high-assay, low-enriched Uranium (HALEU), which is traditionally only produced in Russia. The NRC stated that its staff is expecting to issue the permit shortly.

The U.S. Department of Energy has awarded American Centrifuge Operating (a subsidiary of Centrus Energy) and General Matter (backed by tech billionaire, Peter Thiel), $900 million to each of them for the 'development of domestic HALEU.

HALEU fuel is uranium enriched to almost 20%, instead of the current 5% level used in reactors. HALEU is only enriched up to 12%, as non-proliferation activists want to avoid militants attempting to make crude nuclear weapons from targeting its supply chain.

The Advanced Reactor Demonstration Program of the DOE provides funding up to $2 billion for the Natrium reactor.
