The Nuclear Regulatory Commission (NRC) has granted TerraPower approval to construct a new nuclear reactor in Wyoming, marking the first such permit issued in nearly a decade. Established in 2015 by Bill Gates and supported by Nvidia, TerraPower is collaborating with GE Vernova Hitachi on the design of its Natrium reactor, which will produce 345 megawatts of energy. Although it is approximately two-thirds smaller than conventional reactors, Natrium is considerably larger than several small modular reactor concepts developed by competing startups.
Distinguished by its use of molten sodium for cooling—rather than the conventional water used in most reactors over the past fifty years—Natrium aspires to enhance safety. This approval represents the first commercial reactor to utilize sodium cooling in over four decades. The reactor will maintain an excess of molten sodium in insulated tanks, storing energy for use during periods of low demand. This innovative approach allows for sustained nuclear fission, optimising performance for wind and solar power when those sources dip, thus potentially reducing overall operational costs.
TerraPower’s success in navigating the extensive permitting process is noteworthy, particularly since the NRC’s recent approval comes in light of emerging safety regulations by the Department of Energy—which now apply only to agency-owned lands. The demand for expanded electricity generation, particularly from data centres, has further pushed for the construction of new nuclear facilities under the Trump administration, drawing increased interest from various tech-backed nuclear startups.
Over the past few months, investors have shown significant enthusiasm for nuclear innovation, pouring over $1 billion into the sector, with TerraPower alone raising $1.7 billion, including a recent $650 million investment.
However, nuclear power continues to encounter challenges. It remains one of the most costly energy generation methods today, burdened by expensive power plant constructions and competition from rapidly advancing solar, wind, and battery technologies that have significantly reduced their costs. Despite aspirations to streamline expenses through mass manufacturing, the viability of such strategies remains untested, and benefits are often delayed by up to a decade before cost savings manifest.
In essence, while the approval of the Natrium reactor represents a critical step forward for TerraPower and the nuclear sector, the journey toward making nuclear energy a more financially competitive option is ongoing, necessitating innovative solutions and further investment.
