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.

Energy spectra of delayed neutrons from the mass-separated fission products 79(Zn, Ga), 80, 81Ga, 94, 95Rb, and 129, 130 In have been measured. The neutron envelopes are deduced and compared to predicted envelopes using various mass formulas. The agreement is good for all precursors except for 79(Zn, Ga), whose predicted neutron window is too narrow to reproduce the experimental results.
