Abstract (en)
[origin: EP0355628A1] The invention relates to a process for chemically decontaminating the surface of a metallic construction element of a nuclear power plant. It is provided that the surface is treated in a single-stage process with an aqueous solution which is free from the carboxylic acid oxalic acid and contains another carboxylic acid (3, 6, 8, 11, 12). Suitable carboxylic acids are dihydroxytartaric acid (6), tartronic acid (8) or mesoxalic acid (3). <IMAGE>
