The ambiguity of "salt" is unfortunate here. The "salt" in "molten salt" is a salt, but not table salt (so, no sodium). The one proposed here is a lithium fluoride/uranium fluoride salt. Conversely, while table salt has sodium in it, the sodium in the sodium reactor isn't part of table salt, it's pure sodium metal. (Turns out they explode, also, so there's not much enthusiasm about them anymore.)
