Method and apparatus for electrochemically decomposing inorganic materials contained in an aqueous radioactive

摘要

The invention is directed to a method for electrochemically decomposing inorganic material contained in an aqueous radioactive waste solution. The solution is concentrated by evaporation in order to reduce its volume for further treatment as a waste solution. In order to achieve a more effective decomposition of inorganic compounds in the aqueous radioactive solution, an electrolytic prosess is performed during evaporation of the waste solution with the electrolytic process effecting the electrochemical decomposition. An apparatus for carrying out the method includes an evaporator for accommodating the waste solution and the evaporator is configured as an electrolytic cell.
