Inside the fight over alternative sub fuel
A handful of lawmakers want the Navy to research low-enriched uranium fuel to reduce nuclear weapons proliferation. But funding bans are on the horizon.

NAVY NUCLEAR CONGRESS SCIENCE
There’s been a small but persistent push to get the Navy to look at using low-enriched uranium—instead of the highly enriched variety—to power its future submarines. But Congress is poised to slam the door on more research, at least for the next year, and that could scuttle the possibility of using it on the next generation of U.S. subs.
The push is led in the House by Rep. Bill Foster, D-Ill., a former high-energy physicist who contends that the United States would be safer if it developed warship reactors that did not require highly enriched uranium, which can be used to build nuclear weapons.
“It's a crucial thing that we will continue R&D. We know it's possible to build submarines that have low-enriched uranium—the French do it, the Indians do it, the Russians do it. It's possible to do this. And the question is, how do you minimize the performance trade-off and enough to convince countries that this is a better route than maintaining a large stockpile of weapons-grade uranium?” Foster said at a recent House Rules Committee hearing on the 2024 defense authorization bill.
