Uranium is way the f off in this mod. I have 110 chem plants doing adv rocks (with filters), into 75 mk3 assemblers making sand, into 15 centrifuges (divide each of those by 5 to make a "block" design that can be blueprinted/tiled). A) This uses an INSANE amount of coal (200 greenhouses -> 2 blue belts) just to recycle the filters, and B) only makes 36 uranium ore per MINUTE!
In order to make 0.125 u235/min, you'd need 6,400 hexasulfide, which needs around 280 ore/min, and 11,000 sulfuric acid/min. I would need 35 "blocks" like above to achieve that, nearly 900 chem plants, 583 assemblers, etc. That's ridiculous.
No way is it more efficient to use purple science. You'd need 100 centrifuges making purp to achieve 0.125 u235/min, which means 750 railroad/min alone.
This needs to be improved. I ran my "5 blocks" above for over 12 hours, and only got 3 u235.
