I know the theory and all the half-experiments. None ran a full load of fuel or reached steady state isotope mixture. None ran on what they bred. None even pretended to have a sustainable or economical separation process. It’s scifi.

Accessible (ore as or more more energy dense than low grade lignite that isn’t buried so deep it can’t be extracted without emittingnmore than just using fossil gas) U235 resources assumed to exist (not found) are years to a couple of decades for the world’s 2030 energy needs. Developing every known resource now would have zero impact on a net zero timescale. Even at current costs the raw uranium to run an SMR is at price parity with the module part of a PV installation.

Stop with the damn lies.
