Abstract

The fission product strontium (Sr), after generation in the reactor due to fission of 233U, might exist as SrF2 in the molten fluoride medium of molten salt reactor (MSR) using fluoride carrier salts. The high temperature interactions between the strontium fluoride (SrF2) with the fertile fuel component and thorium fluoride (ThF4) leads to form single ternary compound SrThF6(s). The Gibbs energy of formation is the driving force for formation of any compound. In the present study, standard molar Gibbs energy of formation SrThF6(s) has been determined using an e.m.f. technique using CaF2(s) as solid electrolyte. Using the experimental thermodynamic data, to study the stability domain of SrThF6(s), the chemical potential diagram of Sr-Th-F-O system and ternary phase diagram of Sr-Th-F2 system have been calculated.
