Molten salt. Lower pressure, higher efficiency, and I believe less reactive in the event of an uh-oh.

The molten salt is used as the first step. It then makes steam through a heat exchanger. Molten salt is safe next to the actual tractor because water is not a good coolant in case of emergency.

Also a ridiculously high heat capacity. It does make sense.
