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.

Dose as a function of depth in tissue has been calculated for the case of solar-flare protons incident isotropically on slab shields followed by tissue slabs. The flare used has a spectrum that is exponential in rigidity with a characteristic rigidity P0 of 80 MV. Only incident protons with energies between 0 and 400 MeV are considered. Slab thicknesses of 4 and 20 g/cm2 of aluminum are considered and a tissue thickness of 30 cm is used. In general, it is found that the secondary contribution to the dose is small unless thick shields are considered. In particular, the secondary neutrons from flare protons with energy of less than 50 MeV do not contribute appreciably to the dose in the cases considered here.
