Abstract:
An overview of the research of the Boreskov Institute of Catalysis SB RAS in the field of the use of catalytic processes to neutralise the mixed organic waste containing radionuclides is given. An ecologically friendly technology was proposed for ecologically safe neutralization of mixed organic wastes containing radionuclides U, Pu and fission products. This technology is based on flameless low-temperature oxidation of the organic component of the waste in a fluidised bed of catalyst granules and the transition of radionuclides into the compact solid phase for subsequent processing or disposal. The technological scheme includes a catalytic reactor for waste oxidation and a flue gas purification system. The process was investigated on experimental installations during the catalytic combustion of model mixtures and real radioactive waste containing uranium formed in the production of fuel rods. Various regimes of catalytic combustion of mixed waste and gas purification processes were elaborated. Based on the research conducted, a technological scheme and a technical project of the demonstration plant for the treatment of mixed organic waste were developed. The plant was constructed and assembled at the JSC Novosibirsk Chemical Concentrates Plant. For neutralization of the wastes of extractants containing radionuclides, oxidation in catalytically active melts was investigated. The effect of melt composition, oxygen concentration, load and temperature on process efficiency was studied. Optimal process parameters were determined. On the basis of these results, an experimental installation for processing real liquid organic wastes (worked out extractants) containing U and Pu radionuclides was designed and built at the Siberian Chemical Combine. Installation tests demonstrated the high efficiency of the oxidation of organic components of the wastes and complete absorption of phosphorus and radionuclides U, Pu by the melt
