Description
The kinetic properties of Ni2+ in FLiNaK + 1 mol% NiF2 molten salt electrolyte were determined at T = 475–550 °C using voltammetry (CV) to gain an understanding of molten salt reactor (MSR) fuel salt mass transport properties. A three-electrode electrochemical cell consisting of a glassy carbon working electrode (WE), nickel wire reference electrode (RE), and a nickel wire coil counter electrode (CE) was employed to estimate the diffusivity (7.28 x 10-7 cm2 s-1 at 500 °C) and activation energy, (102 kJ mol-1) of the Ni2+ in FLiNaK. Kinetic properties determined through this work were compared to available literature which showed comparable Ni2+ diffusivity values. The cyclic voltammetry of the Ni2+/Ni deposition and removal steps at scan rates of 50–300 mV s–1 indicated Nernstian behavior for the soluble/insoluble electrochemical system. The diffusivity and activation energy results will serve as a critical resource for future modeling of fluoride molten salt kinetic properties to drive research and development of MSRs.
