(Co-)Precipitation

At low concentrations, sorption to mineral surfaces will be the dominant mechanism retarding radiouclide migration in subsurface environments. However, radionuclides can also be removed from the solution phase through co-precipitation as new mineral phases are formed and, at higher radionuclide/ ligand concentrations, by precipitation. At lower concentrations, co­precipitation will be the more important process.45 For the actinides, hydrolysis can occur […]

Nuclear Safety

Since its inception people have asked the question: is nuclear power safe? During the forty years that commercial power plants have operated worldwide, there have been about eight dozen major accidents, three of which -Windscale (1957), Chernobyl (1986) and Fukushima (2011) — were especially serious. At Chernobyl, 31 worker deaths were recorded immediately and it is estimated that there were […]

Other Potential Wastes

Some existing radioactive materials not currently designated as wastes due to their potential economic value may be declared as waste in the future and thus may need to be managed through geological disposal.[36] Such items include spent fuel from UK nuclear reactors that is not already contracted for reprocessing; uranium and plutonium stocks from spent fuel reprocessing; uranium from fuel […]
