Front-end nuclear fuel supply cooperation: Turning allied interdependence into strategic advantage
The global nuclear revival, which is fueled by unprecedented demand for firm, affordable, dispatchable power for artificial intelligence and data center build-out, energy security imperatives, and climate commitments, has exposed a structural reality of the Western fuel cycle: No single allied nation currently possesses the full suite of front-end capabilities. From mining through conversion, enrichment, fabrication, and the emerging deconversion and metallization steps required for reactor fuels, capability is distributed across Canada, France, Japan, the United Kingdom, and the United States (collectively, the “Sapporo Five”), as well as a small group of close partners.

An accurate database is used to study optical model fits to total neutron cross sections of 56Fe in the resolved and unresolved resonance regions. Averages over resolved resonances are calculated from resonance parameters in a Reich-Moore (reduced R matrix) approximation with Lorentzian weighting. Optical potential parameters are obtained for the s, p, and d waves that reproduce the smoothed cross sections in the resolved resonance region. The p-wave optical potential is found to differ from the s-wave potential. When the appropriate higher angular momentum contributions are added, the average total cross sections can be fitted quite well, from the resolved resonance region all the way up to 20 MeV.
