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.

Depleted uranium was irradiated in the thermal neutron flux of the Low Intensity Test Reactor at Oak Ridge National Laboratory. From mass spectrographic analysis of Pu240 and from chemical determination of Pu content, the effective capture cross section (including both thermal and epithermal neutron capture) was determined for Np239 to be 80 ± 15 barns.
