| titleOfInvention | Ozone oxidation of deposits in cooling systems of nuclear reactors |
| abstract | ABSTRACT OF THE DISCLOSURE Disclosed is an improved process for oxidizing chromium in deposits in the cooling system of a nuclear reactor using a solution of ozone. The improvement con-sists of adding to the solution about 0.01 to about 0.5% of a water-soluble cerium IV compound, about 0.1 to about 0.5% of a water-soluable aromatic compound having at least one ketone group on an aromatic ring, or adding both. Also disclosed is the composition of water, ozone, the cerium IV compound and the aromatic compound. Also dis-closed is a process for decontaminating the cooling system of nuclear reactors by adding a decontamination composi-tion to the coolant, circulating the coolant between the cooling system and a cation exchange resin, removing the decontamination composition by passing it through an anion exchange resin, adjusting the temperature to 40 to about 100°C, adding the ozone oxidation composition, circulating the coolant through the cooling system, raising the tem-perature to at least about 100°C, passing the coolant through an anion exchange resin or a mixed resin, adjust-ing the temperature to about 60 to 100°C and repeating the addition of the decontamination composition and its removal. |
