Electrolytic methods on the threshold to industrial application

The development of the electrolytical reduction technique has been pursued along two lines, thoroughly testing the two types of extractors projected for use in future installations. The electrolytic pulsed column has been tested in the PUTE Pu testing cycle on a kilogram scale (2B-ELKE), and in a non-radioactive environment on a ton scale (1B-ELKE). The testing of the electrolytic mixer-settler (2B-EMMA) in the WAK demonstration plant in a medium-level radioactive environment (Pu purification cycle) has brought about long-term experience under production conditions which within short will be supplemented by tests in the high-level radioactive environment of the first cycle.
