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 experiment to measure the detailed energy, angular, and spatial distribution of neutrons originating from a 14-MeV neutron source in liquid air is presented. The neutron spectra are measured with a proton-recoil NE213 scintillator combined with a collimator. The measurements cover the energy range from 2 to 18 MeV at eight different angles from 0 to 90 deg. The distance between the neutron source and the measurement position varies from 60 cm (52 g/cm2) to 150 cm (130 g/cm2) in liquid air. The results are discussed and compared with known theoretical neutron transport calculations.
