600 asteroid booster parts needed
that means 300 enriched uranium 20%
1500 regular uranium
9000 yellowcake
54000 uranium ore
That's like 4 hours of the world mine operating at 6x.

Is there an easier way? The nuclear recipe spaghetti is confusing but it looks like no free lunch here.

Also it seems that there's no good way to get rid of depleted uranium. I thought you could make it straight into blanket fuel last update, now requires enriched blanket fuel and seems that would take away from the core fuel production.
