Hello Fussion Reactor has only half of interface no imput slots nothing

...
Again, do you mean fission or fusion - your answer of fussion is a weird mix of the two, and, quite interestingly, could easily be a typo or misspelling of either one.

Sry FUSION

Ok - are you trying to insert items into the reactor? If you are, then that's not how it works anymore - you need to pump fluid fuels into it. The available fuels are hydrogen, deuterium, tritium, helium-3, molten lithium-6, molten lithium-7 and molten boron-11. Simply build the electromagnet ring, pump these into the fusion core and heat the reactor up to begin nuclear fusion reactions :)

Sorry, is this the fission reactor or the fusion reactor?

Fusion Reactor

I'm going to close this issue as there didn't seem to actually be an issue.
