It's insane how efficient nuclear power is. I'm pulling an average of 5GW out of pure nuclear, and it's taking ~120 ore/m (which is four miners with prod 10, or eight whole miners with 0 mining prod).

The condition is for when the train leaves. Right now, it looks like you're emptying out the train at "Uranium" and filling it up at "nuclear plant", which is the opposite of what I would expect.
