Control of microbiological processes during long-term storage of radwastes

The chemical and physical methods of controlling microbiological processes during long-term storage of nitrate-containing radwastes in the liquid form in deep reservoir beds as well as incorporated in a cement matrix in surface storage facilities are examined. It is shown that irrespective of the fi...

Description
Summary:The chemical and physical methods of controlling microbiological processes during long-term storage of nitrate-containing radwastes in the liquid form in deep reservoir beds as well as incorporated in a cement matrix in surface storage facilities are examined. It is shown that irrespective of the final method used for disposal of radwastes biogenic processes are best controlled by directed suppression or stimulation, which can be accomplished by adjusting the ratios of the physical and chemical storage parameters: temperature, pH, ionizing radiation, concentration of nitrate ions and other potential substrates for culturing bacteria as well as action by adding biocidal agents.
