Abstract: A method was proposed and a calculation of the ZrO₂ content in the (NaCl-KCl)_equiv-UO₂Cl₂-ZrCl₄ melt for different values of current density (0.08-0.63 A/cm²) and the ZrCl₄ concentration (0-12.3wt%) was carried out on the base of  known composition for one UO₂-ZrO₂ cathode deposit.  A qualitative and satisfactory quantitative accordance of calculated and experimental values of the ZrO₂ content in the UO₂-ZrO₂ cathode deposits was established.
