So are LWRs. With MSRs one doesn't get a runaway nuclear reaction like it happened at Chernobyl and no hydrogen explosions (it doesn't use water as a coolant) like it happened at Fukushima. Also the fuel doesn't ignite in contact with water, like in sodium cooled reactors. The reactor vessel doesnt need to be pressurized, which is a huge safety advantage. Fortunately there are no also issues with spent fuel pools? One thing to watch out for is that the molten salt tank doesn't rupture or leak. Flourine based molten salts are quite corrosive.

Seems like they are going with "Molten Chloride Fast Reactor "[1] which I have no idea what kind of eutectic mixture will make this up (can't find anything besides marketing), maybe its something similar to what I was exploring back in early 2019 with various ionic chlorides with alkali earth metals [2].
