Tutorial talk:Circuit network cookbook
I'm uncertain as to editing practices on this wiki, but wanted to mention something I feel could be worthy of note, a circuit network recipe for controlling usage of uranium-235 and uranium-238 between nuclear fuel and other usages to ensure there is always fuel for the reactor.
Set up a conveyor with a splitter to create two conveyors, one for uranium-235 and one for uranium-238. Have these two conveyors run by two inserters that each feed a container, each container feeds an inserter delivering its contents to an assembly machine making nuclear fuel. Hook the first two containers up to the inserters feeding them from the conveyor, as well as the tile of conveyor after the tile the inserters are drawing from. Set both the inserters to disable when the amount of uranium (235 or 238, whichever either is taking) in the container reaches X amount, and the conveyors to disable when the amount of uranium is below the same amount. Have the assembly machine deliver its product to a third container, and connect that container to the inserters feeding the assembly machine from the uranium containers, with the enable condition nuclear fuel = 0. This container will be the one that feeds your nuclear reactors.
With this set-up, the first two inserters will grab uranium until they reach quota, and until they do the conveyors are disabled to ensure the uranium will not pass by them by. Once quota is met the conveyors enable and the inserters disable, allowing excess uranium to continue down the conveyors to other machines. Meanwhile that stored uranium will not be consumed to produce nuclear fuel until you have none left in reserve, at which time the inserters passing the uranium to the assembly machine activate, in turn activating the first two inserters to get more uranium from the conveyor.
Thus, you always have a stockpile of nuclear fuel and uranium, and when you run out the consumption of uranium by other machines is halted to prioritize production of nuclear fuel. DrakeyC (talk) 21:33, 1 September 2020 (UTC)
