Australia's proposed nuclear submarine fleet under the Aukus deal will leave behind tonnes of weapons-usable uranium-235, radioactive for hundreds of millions of years and capable of being processed into scores of warheads, nuclear experts have warned. The transfer of highly enriched uranium to a non-nuclear weapons nation sets a dangerous precedent that weakens global control of weapons-usable material.
What Makes Aukus Uranium a Proliferation Threat?
The submarines will use highly enriched uranium (HEU) enriched to about 80% uranium-235—the same level as the atomic bomb dropped on Hiroshima. Even after the submarines are decommissioned, the spent reactor fuel remains weapons-usable. Associate Professor Tilman Ruff, founding chair of the Nobel-prize winning International Campaign to Abolish Nuclear Weapons, told a public inquiry that no nation has resolved how to manage this material securely over geological timeframes.

“In 10,000 years, somebody could still go and dig that stuff up and build nuclear weapons with it,” Ruff said. The Australian government has kept the exact amount of high-level waste classified, but FOI-released documents suggest the legacy is immense.
Comparison: Hiroshima Bomb vs. Submarine Fuel Enrichment
| Weapon/Fuel | Uranium-235 Enrichment | Mass | Weapons Usability |
|---|---|---|---|
| Hiroshima atomic bomb | ~80% | ~64 kg | Direct |
| Aukus submarine spent fuel (per vessel) | ~80% | Hundreds of kg (classified) | Direct, requires processing |
| Typical reactor-grade uranium | <5% | N/A | Not directly usable |
Key Takeaways on Australia’s Nuclear Submarine Legacy
- Weapons-usable uranium from decommissioned submarines will be enriched to ~80% for centuries.
- Global precedent: The Aukus deal could be exploited by countries like Iran to justify similar transfers.
- No permanent solution exists for secure storage of HEU waste over geological time.
- Classified volumes of high-level waste remain unknown to the public.
- Security risks persist for thousands of years, requiring perpetual vigilance.
Expert Warnings and the Proliferation Danger
Former White House national security adviser told the Guardian that Australia’s Aukus deal sets a dangerous proliferation precedent. Other states could attempt to acquire nuclear submarines as a cover for obtaining weapons-usable material. The International Campaign to Abolish Nuclear Weapons stresses that no arrangement can reliably isolate HEU for hundreds of thousands of years.
FAQ
Will Australia's nuclear submarines leave behind weapons-grade uranium?
Yes. The spent reactor fuel from each submarine will be highly enriched uranium (HEU) at about 80% U-235, which is weapons-usable and identical in enrichment to the Hiroshima bomb.
How much weapons-usable uranium will be left behind?
The exact amount is classified, but documents suggest hundreds of kilograms per vessel. With a fleet of multiple submarines over decades, the total could be tonnes.
Can other countries like Iran use the Aukus deal as a loophole?
Experts warn that the transfer of HEU to a non-nuclear weapons nation sets a dangerous precedent that could be exploited by states seeking to acquire nuclear material under the guise of naval propulsion.
Is there a safe way to store this nuclear waste?
No nation has yet resolved the problem of permanently isolating HEU waste over geological timeframes. The material remains hazardous for hundreds of thousands to millions of years.
The Aukus submarine deal may bring strategic benefits, but the legacy of weapons-usable uranium is a burden that will outlast any military advantage. As nuclear experts continue to sound the alarm, the need for transparent and secure management of this material becomes ever more urgent.
