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 total neutron cross section of 242Pu has been measured from 0.0015 to 8000 eV, using PuO2 powder samples in the Materials Testing Reactor (MTR) fast chopper. The data give 26.9 ± 2.0 and 18.5 ± 2.0 b for the 0.0253 eV total and absorption cross sections, respectively. It was necessary to correct the total cross-section data for water contamination and for the effect of scattering by small particles. To determine the proper forms for these corrections, low-energy total cross-section measurements were made using samples of Al2O3 and ThO2. Analysis of resonances below 180 eV gives a resonance absorption integral of 1110 ± 60 b, and a neutron s-wave strength function of (0.99 ± 0.44) × 10−4. (A weighted average of data available on this isotope gives 1175 ± 70 b for the resonance absorption integral and 19.7 ± 1.0 b for the neutron absorption cross section at 0.0253 eV).
