Readily available, low boiling point, non corrosive (relatively), and ecologically safe. What more do you want?

    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 safer next to the actual reactor because water is not a good coolant in case of emergency.
