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 experimental test of several equivalence relations for effective resonance integrals is obtained from measurements of U238 resonance escape probability for lattices of the TRX critical facility, and measurements of the U238 resonance integrals of isolated rods of UO2 and uranium metal. The TRX lattices were H2O-moderated and composed of cylindrical, aluminum-clad fuel rods of slightly enriched uranium metal or UO2. The measurements are in agreement with two forms of equivalence among lattice and isolated rod resonance integrals for a given fuel composition. The equivalence between resonance integrals for fuel rods of different compositions (IT and UO2) does not appear to be as good.
