The U.S. Nuclear Regulatory Commission recently officially approved TerraPower, founded by Microsoft co-founder Bill Gates, to begin construction on a new $40 billion nuclear reactor in Wyoming. This is not only the first newly built commercial nuclear reactor in the United States in nearly a decade, but also marks the official commercialization of a new generation of nuclear energy technology based on liquid sodium.
First time in a decade: The United States restarts commercial nuclear power construction
TerraPower spent several years obtaining approval from federal regulators for this project. According to...New York TimesThe report states that this is the first brand-new commercial nuclear reactor project in the United States in about a decade.
The biggest driving force behind this plan comes from the technology industry. With the development of AI companies and the widespread construction of data centers, the existing power infrastructure in the United States is facing unprecedented demand pressure. Therefore, the industry is actively seeking to build more efficient and lower-cost nuclear power facilities as an alternative source of electricity.
Say goodbye to traditional water cooling: Featuring "Natrium" liquid sodium technology
Unlike traditional light-water reactors, TerraPower has adopted its proprietary technology, named "Natrium," for this project.
• Core technology:This system uses liquid sodium as the basis for cooling and operation.
• Business advantages:Through this technology, TerraPower expects to significantly reduce the construction costs and overall development time of nuclear power plants.
• A $40 billion gamble:The tug-of-war between climate vision and nuclear waste controversy
Despite the tech community's high hopes for nuclear energy, the plan still faces practical challenges and polarized public opinion:
• Supporters' viewpoint:Proponents argue that nuclear reactors are a solution that can stably generate large amounts of electricity without producing the same climate-damaging effects as coal-fired or natural gas power plants.
• The concerns of the opponents:Critics point to the potential safety risks of nuclear energy as its most serious drawback. Meanwhile, some question the generation and disposal of nuclear waste, and whether this will offset its environmental benefits.
Furthermore, this facility, endorsed by Bill Gates, is not cheap to build, with an estimated cost of at least $40 billion.
TerraPower still faces numerous logistical and support challenges in ensuring the nuclear reactor can be operational by 2031 as scheduled.
Analysis of viewpoints
The news that TerraPower has been approved to start construction is considered a major milestone for tech giants in dealing with the "power shortage crisis".
While we see giants like Google, Microsoft, and Meta signing pledges to "not let AI increase people's electricity bills," they are well aware that the intermittent nature of green energy sources such as solar or wind power simply cannot meet the 24/7 uninterrupted "baseload power" demand of AI data centers.
The reason why TerraPower, invested in by Bill Gates, chose liquid sodium technology is to try to break the curse of traditional nuclear power plants, which "often take more than ten years to build and have unlimited budget overruns." If the Natrium reactor can be successfully and safely put into commercial operation in 2031, it will not only change the energy landscape of the United States, but may also become the strongest support for the next generation of gigawatt-scale AI computing centers.
