DOE ‘Nuclear Dominance — 3 by 33’: fuel cycle strategy explained for engineers

30 Second Briefing
The US Department of Energy’s Office of Nuclear Energy has launched the “Nuclear Dominance — 3 by 33” campaign, using the Defense Production Act Nuclear Fuel Cycle Consortium of more than 90 companies to rebuild domestic capability across uranium milling, conversion, enrichment, deconversion, fabrication, recycling and reprocessing. By 2033 the consortium aims to secure a cost-competitive US fuel supply chain, accelerate advanced reactor deployment and move towards a closed fuel cycle. Rapid 60‑day “sprints” will target near‑term actions to cut reliance on foreign enriched uranium and critical materials.
Technical Brief
- Nuclear currently supplies nearly 20% of total U.S. electrical generation, framing baseline fuel demand.
- Consortium spans more than 90 companies across milling, conversion, enrichment, deconversion, fabrication, recycling and reprocessing.
- Defence Production Act authority enables voluntary agreements with U.S. firms to prioritise nuclear fuel availability.
- 60‑day “sprints” are structured as rapid action cycles to deliver discrete supply‑chain interventions.
- Scope explicitly includes fuel for both existing light‑water reactors and future advanced reactor designs.
- Executive orders issued in May 2025 provided the legal and policy trigger for forming the Consortium.
- Ending reliance on foreign enriched uranium and critical materials is a stated objective, not just cost optimisation.
Our Take
The US Department of Energy’s push on uranium and critical materials for “3 by 33” sits alongside its TRACE-Ga and METALLIC initiatives, signalling that nuclear-fuel security is being treated as part of a broader critical-minerals industrial strategy rather than a stand‑alone power policy issue.
With nuclear already supplying about 20% of US power, the 2033 time horizon overlaps with DOE’s current funding calls for critical-mineral demonstration plants, which in our coverage are increasingly targeting domestic supply chains for reactor fuels and associated materials.
Recent uranium exploration moves in Wyoming, such as Myriad Uranium’s Copper Mountain expansion involving historic DOE data, suggest that private developers may see the DPA Nuclear Fuel Cycle Consortium as a future offtake or technical-support anchor if US uranium demand rises under this campaign.
