And even better, most of the things that are dangerous in a traditional reactor is chemically bound to the salt. So even if there is some kind of explosion, these materials would not be vaporized and transported in the air with wind.

So no crazy misinformed graphics all over the news.

So even if you drop a hand-grande into that reactor, it just gone be like throwing a rock into a bucket full of toothpaste. Its gone be a mess but its not gone result in a lot of airborne materials.
