| Abstract Scope |
Molten salt will be used as nuclear fuel mixture and the coolant or heat transfer media in molten salt reactor. During operation cycle, the fission products alter the reaction kinetics, and their spent fuel separation is also challenging for MSR deployment. Therefore, the effect of fission product on the radiolysis product in the molten salt needs to be clarified for safe reactor operation. Technetium-99 is a high-yield problematic fission product with 210,000-year half-life. Rhenium is used while establishing experimental capability as it is the third-row congener of Technetium and a non-radioactive surrogate. Reaction kinetics of solvated electron and dichloride radical anion with rhenium ion were observed in LiCl-KCl eutectic using pulse radiolysis method at the Brookhaven National Laboratory Laser-Electron Accelerator Facility.
