Abstract
A process removes radioactive contamination from wastewater obtained in the decontamination of a cooling circuit of nuclear reactors or of parts thereof or in the course of operation of a nuclear reactor. A MnOprecipitate is exclusively produced in the wastewater with the aid of permanganate ions added thereto as an oxidizing agent and of one or more organic reducing agents present in and/or metered into the wastewater, and the MnOprecipitate is separated from the wastewater.
