Nuclear Fuel: The Most Sophisticated Industrial Product You've Never Learned About
Michael Seely, a fuel engineer who builds and optimizes nuclear reactor fuel, walks through how uranium dioxide pellets, zirconium cladding, and multi-layer assembly design keep fuel intact through years of fission. He covers enrichment economics, bespoke fuel geometries for different reactor types, the rise of accident-tolerant and LEU Plus fuels, and why HALEU production is costly and supply-constrained.
