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.

The maximum safe limits on the storage and shipment of slightly enriched fuels may be increased by the addition of fixed neutron poisons. A theoretical study, verified by experiment, is presented to show that an infinite amount of O.95 per cent U235 enriched fuel will be subcritical when the fuel elements are encased in tubing at least ⅛ in. thick. The fuel elements considered are solid rods of 1.34-in. diameter and tubular elements of 1.37-in. O.D. and O.48-in. I.D. Without the tubing it is possible to make as little as four tons of the fuel elements considered critical.
