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.

Differential cross sections have been measured at the University of Lowell for the ground and first two excited states of 232Th via the neutron time-of-flight technique. The following results are presented for neutron scattering cross sections: (a) excitation functions of 232Th in the incident energy range from 185 to 2400 keV for the 0+ ground state and the 2+, 49-keV state, and in the 480-to 2400-keV range for the 4+, 162-keV state; (b) angular distributions for the 0+ and 2+ states at 185 keV and for the 0+, 2+, and 4+ states at 550 keV. Level cross sections were obtained using these and previously measured angular distributions. The University of Lowell 5.5-MV pulsed Van de Graaff accelerator with a Mobley bunching system was employed to generate neutrons via the 7Li(p, n)7Be reaction. Metallic lithium targets were 8 to 10 keV thick, enabling an overall resolution of 15 to 20 keV to be maintained throughout the measurements. The scatterer was disk shaped. Details of data reduction and finite scatterer size effects are discussed. The experimental results are compared with theoretical results and ENDF/B-V.
