Strategic Insights

— 1 min read

Researchers from the Institute of High Temperature Electrochemistry have made a significant discovery in the field of physics, specifically in the electrochemical extraction of uranium from molten salts. The team, led by Alena Novoselova, has successfully extracted uranium from the electrolyte in the form of alloys on a bimetallic liquid Pb-Sn electrode via galvanostatic electrolysis, achieving an efficiency of more than 96%. This breakthrough has the potential to significantly impact the nuclear industry.

Key Takeaways:

  • The researchers investigated the electrochemical drawdown of U(III) ions in a molten NaCl-2CsCl eutectic using liquid reactive Pb and Pb-Sn cathodes.
  • Cyclic voltammetry and open-circuit potentiometry were used to study the reduction of U(III) ions on these electrodes, revealing the formation of various intermetallic compounds.
  • The conditions for the electrochemical production of individual intermetallic compounds were found, and the principal thermodynamic characteristics of the alloys were calculated.
  • The extraction of uranium from the electrolyte in the form of alloys on a bimetallic liquid Pb-Sn electrode via galvanostatic electrolysis achieved an efficiency of more than 96%.
  • The researchers identified UPb3, UPb, U(Pb-Sn)3, and USn3 as the intermetallic compounds formed during the process.
  • The study was conducted over a temperature range of 823-973 K.
  • The findings have significant implications for the nuclear industry, where efficient uranium extraction is crucial for nuclear power generation.
