The U.S. Department of Defense is exploring ways to extract energy from spent nuclear fuel, potentially creating long-lasting power sources for military applications. While civilian nuclear power has not delivered on early promises of cheap, abundant energy, the waste it generates remains a potent resource. This shift reflects a growing need for self-sufficiency in critical materials and a desire to leverage nuclear technology beyond traditional reactor fuel.
The Problem of Nuclear Waste
Spent nuclear fuel contains highly radioactive materials that remain thermally hot for years and hazardous for millennia. Current practice involves storing this waste, but some see it as an untapped energy source. Companies like Project Omega, a Rhode Island start-up, propose recycling this waste by extracting usable elements and reintroducing them into reactors or other technologies.
Why this matters: The U.S. currently relies on foreign sources – primarily Russia – for certain radioactive isotopes vital for medical and military applications. This dependence creates a strategic vulnerability, as Moscow could disrupt supply at any time. Domestic recycling would mitigate this risk.
The Military Applications
The military stands to benefit significantly from recycled nuclear waste. Long-lasting power sources could be deployed in remote outposts, autonomous drones, space-based sensors, and even vehicle convoys, reducing reliance on vulnerable fuel supply lines. President Trump’s executive orders in 2025 signaled support for advanced nuclear reactor development, further accelerating this trend.
The advantage: Unlike traditional batteries or fossil fuels, nuclear-powered systems require minimal refueling, making them ideal for sustained operations in harsh environments.
The Plutonium Problem and Molten Salt Solution
A major obstacle to nuclear recycling is the production of plutonium, a key component in nuclear weapons. The U.S. has historically discouraged reprocessing due to proliferation concerns, pressuring allies to avoid it as well. However, Project Omega proposes a molten salt extraction process that minimizes plutonium risk.
How it works: The company heats a salt mixture (like lithium chloride) and mixes it with radioactive waste, then uses chemical reactions to separate pure metals. This process still produces plutonium, but it remains trapped in a complex mixture, making it harder to weaponize.
U.S. Dependence and Strategic Self-Sufficiency
The U.S. currently purchases radioactive isotopes from Russia, creating a strategic choke point. Project Omega’s in-house recycling would reduce this dependence, bolstering national security. The company has already received an award letter from the Defense Advanced Research Projects Agency (DARPA) and is collaborating with the Department of Energy’s Pacific Northwest National Laboratory.
The goal: To create a closed-loop system where nuclear waste is not buried but reprocessed into usable energy, ensuring long-term self-sufficiency for both civilian and military applications.
The revival of nuclear waste offers a strategic advantage. By turning trash into treasure, the U.S. can reduce reliance on foreign suppliers, enhance military capabilities, and unlock untapped energy potential.
