TerraPower has been issued the first U.S. nuclear construction permit in 8 years for the $4bn Wyoming reactor project. The permit allows the Bill Gates-backed company to build a sodium-cooled reactor in Western Wyoming. TerraPower filed for the permit in 2024 and construction is now set to begin within weeks. Moreover, completion of the up to $4 billion plant is targeted for 2030, according to TerraPower.

The move comes as Microsoft co-founder Gates is eyeing nuclear generation as a power source for the electricity-hungry data centers behind artificial intelligence. Bill Gates is a founder of TerraPower and its primary investor. “We have spent thousands of manpower hours working to achieve this momentous accomplishment,” TerraPower President and CEO Chris Levesque said in a statement.

The plant is set to be built near a coal-fired power plant that is being converted to burn natural gas outside Kemmerer. It is a town of about 2,500 people some 130miles (210 kilometers) northeast of Salt Lake City. Other recent significant nuclear project include the Kairos Power Hermes Low-Power demonstration reactor, US’ First Fourth-gen Nuclear Reactor, in Oak Ridge, Tennessee.

Scope on the TerraPower Reactor in Wyoming

TerraPower seeks to develop the Wyoming reactor as a next-generation nuclear plant that would revolutionize power generation. The 345-megawatt reactor is expected to produce up to 500 megawatts at its peak, enough energy for up to 400,000 homes. Construction at the TerraPower plant site commenced in 2024. However, the construction process does not entail the reactor itself.

The reactor construction permit for a TerraPower subsidiary is the NRC’s first approval for a non-light-water commercial reactor in more than 40 years. These remarks were noted by NRC said in a statement. Virtually all of the world’s commercial nuclear reactors use water to control reactions and transfer heat to drive turbines and produce electricity. The TerraPower reactor would use molten sodium, not water, as a coolant. The last commercial non-light-water reactor in operation in the U.S. was the Fort St. Vrain nuclear plant in northern Colorado.

However, the problem-plagued, helium-cooled plant produced electricity from the mid-1970s until it was shut down in 1989. In October, Gates told reporters he thinks nuclear power will be a “gigantic contributor” to powering data centers. “I wish I could deliver nuclear fission like three years earlier than I can, because then we’d have a perfect match to the current demand pattern of these data center guys,” he said.

The Challenges Facing Nuclear Power in the U.S.

The Trump administration is pushing toward nuclear power through projects such as the TerraPower reactor in Wyoming. Despite this, there are several challenges that seem to be emerging. For instance, the federal government has yet to address the thousands of tons of spent fuel that have been piling up for decades at nuclear plants nationwide. New Mexico and Texas are making effort to keep from becoming dumping grounds in the absence of a permanent solution.

However, In January, the U.S. Department of Energy announced it was taking what it called a first step toward possible partnerships with states to modernize the fuel cycle. These entails reprocessing spent fuel and also disposing of waste. The agency gave states until April 1 to step forward if they’re interested in participating. The TerraPower reactor would produce relatively less nuclear waste than conventional reactors, according to the company.
