PROCESS FOR TREATMENT OF WASTE WATER FROM THE DECONTAMINATION OF A METAL SURFACE FROM THE PRIMARY COOLING CIRCUIT OF A NUCLEAR REACTOR, NUCLEAR REACTOR WASTE WATER TREATMENT DEVICE AND USE OF THIS DEVICE

摘要

A method for treating waste water from the decontamination of a metal surface in a primary coolant circuit of a nuclear reactor comprises discharging a predetermined amount of an oxidation solution from the primary coolant circuit into a reduction zone connected to the primary coolant circuit and reacting the oxidation solution with a reducing agent to form a reaction solution that is freed of oxidizing agent, and passing the reaction solution over an ion-exchange resin in order to form a desalinated solution, and returning the desalinated solution to the primary coolant and/or disposing of the desalinated solution. A waste water treatment apparatus for carrying out the method is also provided.
