Reducing radioactive contamination of reactor constructional materials

摘要

The constructor materials are in contact with soluble radioactive mateterial. An oxide film is formed ele-electrically on the construction materials during anode polarisation. Iions are eluted from the construction materials and react with oxygen ions dissolved in the liquid. An iron oxide film is formed on the material. A reference electrode is put in the liquid and a potential difference applied between it and the combustion materials. This kept at such a level as to form an oxide film. Liquid containing dissolved oxygen passes through pipe (2) under the action of the circulation pump (4). The hole (8) which is to be given the oxide film is in the circuit.
