| Abstract Scope |
The molten salt reactor is one concept selected by the Generation IV forum in 2001. This concept, based on the use of a liquid fuel, consists of salts mixture melted at high temperature. The first concepts were based on the U/Th fuel cycle. Recently, researches have been carried out in order to adapt this concept to the U/Pu fuel cycle which is the French reference cycle. Neutronic studies evidenced the requirement to replace the fluoride salt with a chloride salt because the fluorides thermalize the neutron spectrum.
Fluoride salts were the subject of studies for many years. The use of chloride salts necessitates academic research, in particular on their reactivity towards water and oxygen and on the behavior of actinides (or their simulant) in these solvents. This talk presents the preliminary studies realized on this topic and comparison between chloride and fluoride salts from the viewpoint of chemical safety issues. |
