Replying here because I can no longer edit. Yes, my bad. I confused this with something I read a long while back (~10Y). Energy production uses enrichment in ~20% range. Thank you for generously correcting my answer. As for a follow-up, I genuinely mixed up with something on the general ballpark of '90-94%' -> Is it something about Thorium-based breeder reactors? What kind of processes use high enrichment in this range
