There isn’t really any reason to enrich to 60% if you aren’t going for weapons grade, 20% HALEU fuel is the highest breakeven I know of where the benefit to enrich to 20% can in certain reactors outweigh the cost of enrichment but even then 20% is considered uncommonly high for most power plants 60% is just another beast with a hugely added cost
Good reason to be suspect but I don’t know if it’s enough to claim they are enriching to that level.
