Not news, but AI can provide some odd answers that might be completely wrong. I asked Google AI about the difference in initial fuel load for fast reactors compared to thermal reactors. As a Navy Nuke trained in arrow analysis - go ahead and ask - I thought I knew that fast reactors need higher fuel loads to go critical and that's one of the reasons nearly all commercial reactors are thermal. I was seeking to quantify my assumption. But Google AI told me that "Fast reactors require significantly less initial uranium fuel loading compared to thermal reactors to achieve the same power output." Am I wrong or is the AI hallucinating again?
