try this: "Large Reaktor": [Ingot/Uranium:XX:P1]
Container: [Ingot/Uranium:P2]

Cy's correct, that's how I setup my reactor's on my base, except I also went ahead and put the :Split operator on there as well in case I didn't have the number of ingot's they all required.

Though on my container (for me "Ingot Storage" ), I have [Ingot:P10] I've taken to manually setting the Priority for all my containers, helps me keep track a bit better now. All my storage type bins (ore bin, ingot bin) get a P10 (what I'm using as my lowest) and everything else is getting something between 1 and 5.

I've also learned the hard way to set the [Exempt] flag on all my reactors as if you dock a ship using a connector with a container named as above, it will suck all the ingots out of your ship's reactors.

you could try "Uranium:Ignore" tag on each of your ingot bins

I do this with all my reactors all the time. I name them "Reactor [uranium:p1:10, exempt]", and they with automatically replenish themselves with 10 ingots of uranium and leave any extra in the network, and nothing can pull the uranium out by accident either. Try experimenting with variations like that, and see how you like it.

It seems still broken to me.
Setting [Ingot/Uranium:1:P1] on reactor not stopping it from pulling all available uranium ingots from system.

[Edited: solved]
Just strip 'Use conveyor system'
