OPINION - In the face of climate change, nuclear power is increasingly being championed as a clean energy solution. Advocates highlight advancements such as small modular reactors (SMRs) and high-assay low-enriched uranium (HALEU) as the future of the industry. They also push for the revival of decommissioned plants like Three Mile Island, claiming they are essential to energy security. But behind the promises lies a sobering reality: nuclear energy remains fraught with safety concerns, aging infrastructure, and unsolved waste issues that make it a hazardous bet for the future.
HALEU: A Fuel Fraught with Risks
HALEU is a new type of uranium fuel enriched to between 5% and 20% uranium-235—more than the typical fuel used in current reactors. While touted for its efficiency in advanced reactors, it presents significant risks. The U.S. Department of Energy has acknowledged that the production, transportation, and storage of HALEU require new infrastructure, which is not yet in place. Furthermore, relying on HALEU increases proliferation risks since it is closer to weapons-grade uranium than traditional reactor fuel.
The United States currently lacks domestic HALEU production capacity and depends on imports from countries like Russia. In a 2022 report, the U.S. Government Accountability Office highlighted this reliance as a critical vulnerability, raising questions about the sustainability and security of HALEU-based reactors.
SMRs: The Illusion of Safety
Small modular reactors are marketed as a safer, more flexible alternative to traditional nuclear reactors. However, multiple studies reveal that SMRs generate significantly more radioactive waste per unit of energy produced. A 2021 study published in Proceedings of the National Academy of Sciences found that SMRs could produce up to 30% more spent fuel than traditional reactors, compounding existing waste disposal challenges.
Moreover, the economic viability of SMRs is highly questionable. According to a 2022 analysis by the Union of Concerned Scientists, SMRs could cost more per kilowatt-hour than both traditional reactors and renewable energy sources like wind and solar. This undermines the industry’s claims that SMRs are a cost-effective solution to the energy crisis.
The Risks of Reviving Aging Nuclear Plants
The push to restart decommissioned plants like Three Mile Island—a site of the worst nuclear accident in U.S. history—raises alarm bells about the safety of aging infrastructure. Reactors built decades ago were not designed to operate indefinitely. As they age, components such as reactor pressure vessels, cooling systems, and containment structures degrade, increasing the risk of accidents.
A 2014 report by the National Academy of Sciences warned that embrittlement, corrosion, and fatigue in aging nuclear plants significantly heighten the likelihood of component failures. For instance, the Indian Point Energy Center in New York, which was decommissioned in 2021, experienced multiple leaks and near-misses during its final years of operation. Restarting facilities like Three Mile Island without addressing these risks would be courting disaster.
Radioactive Waste: The Persistent Problem
A critical, unresolved issue of nuclear power is radioactive waste. The United States currently has no permanent disposal site for high-level nuclear waste. Spent fuel is stored in temporary facilities near reactor sites, often in densely populated areas. According to the U.S. Department of Energy, more than 90,000 metric tons of spent nuclear fuel are stored at over 70 reactor sites across the country, with no long-term solution in sight.
The dangers of temporary waste storage are well-documented. A 2022 report by the Nuclear Regulatory Commission acknowledged that even minor leaks from waste storage facilities could contaminate groundwater and ecosystems for centuries. The lack of a permanent repository like the stalled Yucca Mountain project leaves future generations burdened with the environmental and public health risks of nuclear waste.
Lessons from Past Disasters
History is replete with cautionary tales about nuclear energy. The Fukushima Daiichi disaster in 2011 demonstrated how natural events can escalate into catastrophic nuclear accidents. A report by the United Nations Scientific Committee on the Effects of Atomic Radiation confirmed elevated thyroid cancer rates among children in the region, emphasizing the long-term health impacts of radiation exposure.
Similarly, the 1986 Chernobyl disaster continues to affect millions. A 2021 study in Nature documented ongoing ecological damage in the exclusion zone and significant health impacts on populations exposed to radiation. Even the partial meltdown at Three Mile Island in 1979 resulted in costly cleanup efforts and lingering public health concerns, with studies showing elevated cancer rates in nearby communities.
Renewables: A Safer, Smarter Alternative
Rather than doubling down on the inherent risks of nuclear energy, policymakers should focus on expanding renewable energy sources like solar, wind, and geothermal. These technologies are safer, cleaner, and increasingly cost-effective. According to the International Renewable Energy Agency (IRENA), the cost of solar power has plummeted by 85% since 2010, and wind energy costs have dropped by over 50% during the same period.
Unlike nuclear power, renewables produce no hazardous waste and pose no threat of catastrophic failure. They are also quicker to deploy: utility-scale solar and wind projects can be constructed in a fraction of the time it takes to build a nuclear plant.
Conclusion: The Case Against Nuclear Revival
The resurgence of nuclear power—through HALEU, SMRs, or the revival of plants like Three Mile Island—is a high-stakes gamble that prioritizes industry interests over public safety and environmental sustainability. The risks of radioactive waste, aging infrastructure, and catastrophic failures are too great to ignore.
The future of energy lies not in clinging to dangerous, outdated technologies but in embracing renewable energy solutions that are cleaner, safer, and more economically viable. It’s time to put down the radioactive Kool-Aid and invest in a truly sustainable future.
