In a groundbreaking ceremony held in Kemmerer, Wyoming, Bill Gates, the co-founder of Microsoft and chairman of TerraPower, marked the commencement of construction on a next-generation nuclear power plant. Gates believes that this project has the potential to revolutionize the way power is generated and contribute to a zero-carbon future.

TerraPower applied for a construction permit from the Nuclear Regulatory Commission earlier this year to build an advanced nuclear reactor that utilizes sodium, instead of water, for cooling. Once approved, the plant will function as a commercial nuclear power facility. The site chosen for the project is adjacent to PacifiCorp's Naughton Power Plant, which will cease to burn coal by 2026, followed by natural gas a decade later.

The decision to adopt nuclear power stems from the fact that nuclear reactors operate without emitting greenhouse gases, making them an environmentally friendly alternative. PacifiCorp intends to obtain carbon-free power from the TerraPower reactor and is currently evaluating the inclusion of nuclear energy in its long-term planning.

The construction work initiated on Monday aims to prepare the site for the swift installation of the reactor if the permit is granted. While Russia leads in the development of sodium-cooled reactors, the Wyoming project is the first attempt in approximately 40 years to establish an advanced reactor as a commercial power plant in the United States.

Chris Levesque, President and CEO of TerraPower, emphasized the need for advancements in nuclear technology utilizing computer modeling and physics for simpler and more cost-effective designs. The Natrium reactor demonstration project, created by TerraPower, incorporates a sodium-cooled fast reactor design with a molten salt energy storage system.

Levesque acknowledged that the industry has been focused on repeating past performance rather than innovating. However, the increasing electricity demands of the future and the cost challenges associated with current nuclear energy have spurred TerraPower and its founders to prioritize innovation.

While the total cost of the project is estimated to be around $4 billion, with half being funded by the U.S. Department of Energy, Levesque clarified that this figure includes unique expenses associated with the designing and licensing of the reactor. Therefore, future projects are anticipated to have significantly lower costs.

Many advanced nuclear reactors under development in the U.S. rely on a type of fuel known as high-assay low-enriched uranium (HALEU), which has a higher percentage of uranium-235 than conventional reactors. However, concerns have been raised about the potential dual-use nature of HALEU for nuclear weapons. Edwin Lyman, the director of nuclear power safety with the Union of Concerned Scientists, highlighted the importance of raising awareness and strengthening security measures around HALEU as advanced reactor projects progress.

The TerraPower project in Wyoming has been postponed by two years to 2030 because the fuel it requires is currently only commercially supplied by Russia. However, efforts are underway to develop domestic sources of HALEU through the U.S. Energy Department.

As the construction commences on this ambitious venture, Bill Gates expressed his optimism about America's energy future, emphasizing the significance of achieving safe, abundant, and zero-carbon energy. By pushing the boundaries of nuclear technology and embracing innovation, TerraPower aims to play a pivotal role in shaping a sustainable energy landscape for the country.
