Since NRs are running all the time it is horrible to feed only one fuel rod if needed! And why is that a problem and not solvable?
Because there is implementation for CN or LN with the options to read and send the content of the fuel slot and also of the usage from the last consumed fuel.

This is smth. what should have been there since NRs are available so it would be nice to include the CN to this device to have much more control over it

You can always read the available steam coming from the reactor, assuming you have a storage tank connected to the steam output. If you have enough steam: don't put nuclear fuel in the reactor.

I think the limitations are intentional, because it should be a challenge.

Use inventory combinator mod.

It's very easy to read when you eject an empty fuel cell (inserter -> read hand contents) and insert a new one only then. The only tricky part is the initial startup if you want to automate that
