Advanced Nuclear Power Developments in the U.S.

Recent advancements in nuclear power technology are reshaping the energy landscape in the United States. As states strive to position themselves as leaders in advanced nuclear energy, policymakers are exploring subsidies and regulatory reforms. The focus is on small modular reactors (SMRs) and microreactors, which promise to be more flexible and quicker to deploy than traditional nuclear plants. With tech giants pushing for reliable energy sources, the race to implement these innovations is intensifying.

About Advanced Nuclear Reactors

Advanced nuclear reactors, including small modular reactors and microreactors, are designed to produce less energy than conventional reactors. Conventional reactors generate 800 to 1,000 megawatts. In contrast, SMRs produce up to 300 megawatts, and microreactors generate up to 20 megawatts. These smaller systems can be factory-built and are easier to site, making them attractive for specific customers like data centres.

State Initiatives and Legislative Support

States are increasingly recognising the potential of nuclear energy. In 2024, 25 states enacted legislation to support advanced nuclear initiatives. For instance, Tennessee has proposed funding for nuclear projects and established a Nuclear Energy Fund to attract investments. Utah is working on “Operation Gigawatt” to double its electricity generation. Texas aims to lead in advanced nuclear power, while Michigan and Indiana are considering incentives for reactor development.

Federal Support and Funding

The federal government has shown strong support for advanced nuclear technologies. Billions of dollars in subsidies, loan guarantees, and tax credits have been allocated to promote the development of these reactors. The U.S. Department of Energy estimates that an additional 200 gigawatts of nuclear capacity will be needed by 2050 to meet energy demands and achieve net-zero emissions. However, no modular reactors are currently operational in the U.S.

Challenges Facing Advanced Nuclear Power

Despite the promise of advanced nuclear technology, several challenges persist. There is currently no long-term solution for the storage of radioactive waste. Safety regulators face pressure to approve reactor designs amid public skepticism. Additionally, the nuclear industry competes with rapidly advancing renewable energy technologies, which could undermine the feasibility of nuclear power.

Supply Chain and Manufacturing Concerns

The U.S. lacks the necessary manufacturing capabilities for high-quality materials essential for building nuclear reactors. This shortage could result in increased costs and delayed timelines for reactor construction. Moreover, the uranium enrichment capacity in the U.S. and allied nations needs to expand to support the production of these reactors.

Future Prospects for Nuclear Energy

The future of advanced nuclear power remains uncertain. While over 30 advanced nuclear projects are planned, they are expected to contribute only a fraction of the required 200 gigawatts. The success of these reactors hinges on timely deployment and public confidence in their safety and reliability.
