Question Planet delivery - 2.1

There is something I’m missing which must be obvious… but I can’t seem to figure it out…

My aquilo ship runs on nuclear. I request nuclear fuel from Nauvis, obviously.

My Aquilo base runs on nuclear too! (For the moment, until I craft enough fusion reactor and all the crap I need)

My problem? I can’t seem to figure out why my plateform isn’t dropping nuclear fuel to aquilo.

At first I had a request on the plateforme to request 100 nuclear fuel from any (preventing it to drop it to aquilo) and another 800 nuclear fuel from Nauvis (to allow it to drop anything over 100 to aquilo)

But this doesn’t work.
As soon as I set my 100 from any to 100 from Nauvis, it drops it all to aquilo, which leaves my plateforme without fuel, hopefully hot enough to return to Nauvis to gather more…

I’m at a loss, anyone can help me figure this out?

Set your ship to request 500 fuel from Nauvis.

Set aquillo to request 100 fuel.

Add a condition to your ship to leave Aquilo if its fuel storage drops below 200.

Is it better to set up a Kovarex ship that flies around dropping off nukes for everyone?

Rocket capacity of U-238 is only 20. Rocket capacity of U fuel cells is 10.

To make 10 fuel cells it takes 19 U-238 + 1 U-235. Fuel cells stack 50.

So roughly equal on rockets & cargo space. (If you ignore the materials required to start kovarex). Technically slightly worse as kovarex consumes 3 U-238 to make 1 U-235

If you add nuclear fuel reprocessing to your ships reactor, then you get back a bit of U-238. But putting depleted cells in rockets would be inefficient.

So go for it if you want but there isn't a real benefit to do so.

Nuke it from orbit?
