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

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

Fusion Reactor

...
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 :)

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