If you check here on table 5 you’ll see that common table salt (NaCl) melts at 801º C.
As for what’s used, in Chapter 2 of that paper they say “Molten salts consist of alkali metal or alkali metal halides and oxygen-containing salts”, so it’s not actually table salt that’s used in Generation 2 of those kind of power generators.
How hot does heat need to be to salt melting?
Depends on the salt used.

Thanks!
Do you know of the melting temperatures of any other substance you think I may be interested in?
