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.

A formalism based on the Dirac chord method is extended from a previous paper to provide an analytical method for determining the properties of small fission-fragment sources of arbitrary convex geometry. The fragment escape probabilities, energy spectra, and energy deposition fractions are determined for spherical, slab, and cylindrical uranium-dioxide sources, using an energy-loss model that contains initial-energy spectra and range-energy relations for 42 fragment species. For comparison, calculations are also made, using two simplified energy-loss models. Finally, a method is given for generalizing the results to sources containing materials other than uranium dioxide.
