## Advancing the Future of Nuclear Power: The Push for Advanced Reactors in the United States
The United States is embarking on a new era of nuclear power, with a focus on domestic production of nuclear reactor fuel and the development of advanced reactors. One of the key players in this movement is X-energy, a Maryland-based company that has submitted an application to the U.S. Nuclear Regulatory Commission to license a new fabrication facility. This facility will transform enriched uranium into fuel products, primarily in the form of small, black spheres known as pebbles, each containing a speck of uranium enriched beyond what today's power plants use.
These pebbles, which are coated with protective carbon, are a type of TRISO fuel, known as the most robust nuclear fuel on Earth. X-energy plans to use these pebbles in a high-temperature gas-cooled nuclear reactor they are developing. The company is currently making small amounts of nuclear fuel for testing at Oak Ridge National Laboratory.
The push for advanced nuclear reactors is part of President Donald Trump's goal of quadrupling domestic production of nuclear power within the next 25 years. However, some experts have expressed doubts about the feasibility of this goal, with David Kemp, a Cato Institute policy analyst, stating that it is unrealistic due to the need to build nuclear reactors faster than ever.
The lack of infrastructure for producing high-assay low-enricured uranium, a key component of advanced reactors, is another challenge. Currently, only Russia and China have the capacity to produce large amounts of this uranium. However, progress is being made. In late 2023, Centrus Energy produced the nation's first 20 kilograms of high-assay low-enriched uranium in more than 70 years.
Other nuclear companies, such as Oak Ridge National Laboratory, Standard Nuclear, and Orano, are also aiming to expand production in Oak Ridge, Tennessee. The United States lacks any next-generation reactors operating commercially and has only built two new large reactors from scratch in nearly 50 years.
Critics argue that building more nuclear reactors is too expensive and riskier than other low-carbon energy sources. However, the Department of Energy argues that high-assay low-enriched uranium allows newer reactors to run longer and more efficiently, sit on smaller footprints, and produce less waste. Each pebble could be used about six times, making the fuel more cost-effective in the long run.
As the U.S. moves forward with its plans for advanced nuclear reactors, challenges remain, including regulatory hurdles and supply chain limitations. However, initiatives such as the DOE's pilot program are aimed at expediting the development of advanced nuclear reactors and reducing regulatory delays. Congressional hearings are also focusing on advancing nuclear energy by making small modular reactors and micro modular reactors commercially viable.
With continued efforts to address these challenges, the U.S. could see a new age of nuclear power, with advanced reactors providing a clean, efficient, and reliable source of energy for decades to come.
- The development of advanced nuclear reactors, such as X-energy's high-temperature gas-cooled reactor, is backed by funding from President Donald Trump's goal of quadrupling domestic nuclear power production within the next 25 years.
- The United States is pushing to advance its environmental-science field, focusing on the production of high-assay low-enriched uranium, a key component in the fuel of advanced reactors, by companies like Centrus Energy.
- In the sphere of technology and business, nuclear companies like X-energy and Oak Ridge National Laboratory are seeking finance for projects to expand production of advanced reactor fuel in the United States.
- The sports of climate-change and energy conservation are being played on a global scale, with countries like Russia and China leading the production of high-assay low-enriched uranium, a crucial resource for the future of nuclear energy.
- The finance and industry sectors are closely watching the push for advanced nuclear reactors in the United States, as these new reactors could provide a stable, low-carbon source of energy, benefiting both the environment and the economy.
