PROCESS FOR REMOVAL OF RADIOACTIVE CONTAMINATION FROM WASTEWATER

摘要

The invention relates to a process for removal of radioactive contamination from wastewater obtained in the decontamination of the cooling circuit of nuclear reactors or of parts thereof or in the course of operation of a nuclear reactor, in which exclusively an MnO2 precipitate is 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 this MnO2 precipitate is separated from the wastewater.
