I'm not sure you really want a gigawatt GRAVMAK fusion plant running without qualifies watch standees... Just a little different than a diesel plant; especially with respect to uncontrolled failure modes.
You do not want a human in an event chain no matter what the power plant type. Any event chain with a human as a deciding factor will always fail. Guaranteed 100% to fail.
No nuclear plant today runs with a human in the event chain. None. Nuclear power plants have watch details to alert the mechanics to start fixing some triple redundant system that already auto switch to a backup that still has a backup. Not even Russian ones have humans in the loop anymore. Such power plants have 2 phases. How much power is desired with an auto start/stop, and auto shut down in case of emergency with triple redundant TFT sensors(9 of them). This will be true on a fusion plant as well. Coal fired steam turbine plants are not operating with a human in the event loop. All the watch person does is alert someone if there is a mechanical failure for repair and if an earthquake happens destroying part of the facility where the automatic shut down sequence cannot self engage. Natural gas fired steam turbines do not even have a watch at all other than overall security detail. Giant Diesel powered generators do not even have the security detail.
There is no way even an incompetent engineer is going to have a human operating a fusion plant let alone a competent one. None. Not even the Navy operates with a human in the loop. They were the last to operate this way. I suppose some Chinese or Russian sub may operate that way still.
See Chernobyl why you do not want a human operator. 3 mile island showed how even rudimentary automatic shut down processes save the day without human involvement to screw up by the numbers. Same with the Fujik???spelling??? disaster. The automatics saved the day even when the engineers screwed the pooch initially. Turned a mega disaster into only a disaster. Of course then the human engineers did a final screwjob.
The ONLY reason there will ever be an "engineering" watch on a fusion reactor is for damage control on a military ship. Damage can cause perfectly good automatic machinery to not work as expected. On a commercial ship, do not have this problem and RFC's engineers standing "watch" in the power plant compartment is a waste of human resources.
Anyways, real world clash with RFC universe. Hey, its space Opera not science.
