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 wall heat transfer coefficient for the forced convective two-phase flow of sodium is theoretically derived by using the momentum-heat transfer analogy and a logarithmic law for the velocity distribution in the liquid film. Only one constant in this logarithmic form needs to be empirically determined. The relationship between the film average temperature and the interfacial liquid-vapor temperature is also derived. The results from the suggested correlation are in excellent agreement with the Zeigarnick and Litvinov data over a broad range of parameters. The predictions are also in agreement with the high heat transfer coefficient observed in some General Electric Company experiments. The proposed correlation is found to result in a higher heat transfer coefficient for sodium than do the previously advanced correlations.
