I wonder if it could be combined with a steam turbine or some other process to produce electricity once on the surface of Mars?
“to produce electricity once on the surface of Mars?”
Nothing else come close to nuclear power, when you compare the Space Weight And Power (SWAP) trade offs. Something the size of a five gallon bucket could very reliably produce a few megawatts steadily for ten years.
Per pound, or per cubic foot, nuclear power is the hands down winner for Mars bases (where solar panels are additionally vulnerable to storms).
