Do we – if we build up Nuclear ten-fold? Looks like we've used ~3Mt up to now over 60 years. IAEA says there's 60Mt out when including 'unconventional' resources: https://www-pub.iaea.org/MTCD/Publications/PDF/TE1843_web.pd....

Now, if we use 30Mt for the next 60 years, it doesn't look like enough Uranium for the next 1000 years... (even without considering the fact that those 50Mt of uncovential resources are probably not usable)
