| Abstract Scope |
The fuel or coolant salt in a molten salt reactor after significant time/burnup undergoes compositional changes due to generation of fission products, ingress of contaminants, and formation of corrosion products. The understanding of the equilibrium state of this complex salt is a key issue for reactor control, management of corrosion, and assessment of safety as it provides chemical potentials, phase equilibria, and vapor pressures. Their determination requires a set of Gibbs energy models for the multicomponent systems, including how the components interact in the salt. That need is being addressed in the development of the Molten Salt Thermochemical Database (MSTDB). As the MSTDB component library is expanding it is also including developed representations of many element systems. The presentation will cover how these higher order systems are generated, the current status of the MSTDB, and newly developed higher order systems together with potential implementation through the THERMOCHIMICA thermochemical solver. |
