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.

Photon leakage spectra from thick spherical samples of various materials with a central 14-MeV neutron source were measured. Significant disagreement was revealed between the experiments and calculations as well as between calculations using the data libraries ENDF/B5, ENDF/B6, and ENDL-85. In this paper the experimental and calculated data for samples of Al, Ti, Fe, Zr, and Pb are given. The analysis of experimental errors and reasons for the disagreement is carried out. Corrections of some widespread gamma-production data for fast neutrons are proposed.
