The Fusion Reactor is the exact opposite of a Fission Reactor; instead of splitting atoms to generate electricity, it fuses atom nuclei to form heavier ones, which releases energy as heat in the process. This process requires deuterium and tritium which, you can produce in the chemical extractor and the fission reactor. To input these, you can either pump them in using item transfer blocks like hoppers or right-click the machine with a stack of either. After also being powered from the top or bottom by an energy source, the reactor will emit plasma directly off its sides. This plasma can only be contained using electromagnets. These electromagnets will, in turn, turn water above them into steam on contact with the plasma.
