http://ThoriumRemix.com/ I see moving to molten salt fueled reactor technology as a way to get rid of all the stored energy term problems we look at in today's reactors.

Kirk Sorensen:
Whether it is pressure, whether it is chemical reactivity. Even the potential of fission products in the fuel itself to be released. Those fission products are bound up very tightly in salts.

Strontium and caesium are both bound up in very, very stable fluoride salts.

Caesium fluoride is a very stable salt. Strontium bifluoride another very stable salt. 

In a light water reactor caesium is volatile, in the chemical state of the oxide fuel in a light water reactor. That's been one of the concerns about caesium release. Caesium would not release from a fluoride reactor at all.
