The salts used in these reactors are (according to the Wikipedia article):
MSRs can be safer than ordinary light water reactors. Molten salts trap fission products chemically, and react slowly or not at all in air. Also, the fuel salt does not burn in air or water.
As I understand it, they are using more stable fluoride salts like uranium tetraflouride, which is still potentially reactive with water, but much more slowly and is quite manageable, so I hear.
Although, I do admit to having drunk the Kool-Aid on MSR's, so I hope someone more knowledgeable in the chemistry comes along to correct me if my faith is misplaced.
