These tokamak style reactors have a lot of problems still. They do not scale well.
Heat waste system extraction using memory metals are one viable side alternative.
Low power electrolysis using HF, as another anon mentioned.
Classic nuke reactors are ok, thorium salt has the best long term option of the families as the material is cheap, available and the waste is not very toxic.
