Management of metal chlorides in high temperature processes-Application to the nuclear wastes treatment

► We study the differences observed between modelling and analysis for chlorine linked with metals. ► We explain the differences with the adsorption of chlorine on activated surface. ► We explain the conditions of chlorine realise and we study the consequences of the phosphatation in thermal process. ► We propose to revise phosphatising technique to drive the metals in proper place in the process. ► This study allows to enhance the safety and lifetime of process used to treat hazardous materials.
