How hot is molten fluoride salt?
I wouldn’t take a bath in it.
And how corrosive?
According to this internet thingy, about 600-700 degrees Centigrade.
If memory serves Lithium bromide Solution was used as the heat
transfer medium with water vapor being the Refrigerant in the Servel Gas Air conditioners. They operated at high vacuum, and worked well until they got a leak, then the LiBr would corrode the unit. You couldn’t get them serviced since every one knows that you can’t take fire and make cold, you need a magician for that.
They did not mention which Br salt, Also wasn’t Chernoble a Liquid Sodium cooled unit

From BING....
“Liquid-fluoride-salt heat transfer fluids are proposed to raise the heat-to-electricity efficiencies
of solar power towers to about 50%. The liquid salt would deliver heat from the
solar furnace at temperatures between 700°C and 850°C to a closed multireheat Brayton
power cycle using nitrogen or helium as the working fluid. During the daytime, hot
salt may also be used to heat graphite, which would then be used as a heat storage
medium to make night-time operations possible”
