The Need of ³⁷cl in Molten Salt Fast Reactor for Ecological and Economical Reasons

Abstract

The use of natural chloride in the salt fuel has been sometimes promoted for the chlorine based molted salt fast reactor using for example NaCl-UCl4- UCl3. Most of the chemistry based R&D has been carried out on natural chloride, while in reactor physics most of the calculations are based on enriched chloride-37. In any case, the use of natural chloride (75.77% 35Cl and 24.23% 37Cl) induces ecological and economical issues
