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.

The neutron capture and subthreshold fission cross section of 241Am was measured in the energy range from 10 to 250 keV, using 197Au and 235U as the respective standards. Neutrons were produced via the 7Li(p,n) and the T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon-Rae detector and fission events by a NE-213 liquid scintillator with pulse-shape discriminator equipment. Flight paths as short as 50 to 66 mm were used to obtain optimum signal-to-background ratio. The capture cross section could be determined with a total statistical and systematic uncertainty of 4 to 10% while the respective values are 13 to 20% for the fission cross section. The results are compared with recent data of other authors, which in some cases are severely discrepant.
