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.

Measurements of the spectra of delayed neutrons from the thermal fission of 235U are reported over the energy range 30 to 1500 keV. The resolution is sufficient to identify locations of peaks in the spectra. Spectra for three different count-irradiation cycles are reported with the shortest representing a near equilibrium spectrum for delayed neutrons from 235U. Comparisons with existing data show relatively good agreement to the spectral peaks. A correction for the shield of the detector is introduced and applied to the current and previous work with reasonable results. In general, the new spectra are softer than previously reported and show more detailed structure.
