A method for decontaminating the coolant circuit of water-cooled nuclear reactors
Abstract
The proposed decontamination method involves circulating through the coolant circuit, under a pressure of at least 5 bar, a solution of carbon dioxide and carbonic acid in water with a pH of between 3.0 and 5, and either recirculating the carbonic acid solution through a cation exchange resin to remove iron, or depressurizing the solution into a holding tank and passing an oxygen-containing gas through the depressurized solution to precipitate dissolved iron oxide as ferric hydrocide.
