Definitions
- the object is achieved by eluting radioactive ion exchangers and bringing the eluates into contact with the radioactive metals and / or radionuclides with biosorbents, the radioactive metals and / or radionuclides contained in the solutions being bound to the biosorbents that are loaded Biosorbents are separated from the solutions exempted up to the dispensable limit values of the radioactive metals and / or radionuclides, the biosorbents with the bound radioactive metals and / or radionuclides are subjected to a combustion process which reduces to a very small volume, solid combustion residues of the loaded biosorbents in a material such as glass, cement or bitumen can be enclosed and thus transported to an intermediate or final storage facility for radioactive waste with reduced volume and stable storage.
- biosorbents for the purposes of the present invention, all insoluble materials of biological origin that are capable of biosorbing radioactive metals and / or radionuclides can be used as biosorbents.
- Biosorption which can be carried out with biosorbents, is a relatively new and very economical way of removing toxic metals from the environment (Biotechnol. Prog. 1995, 11, 235-250 and Appl. Microbiol. Biotechnol. 1997, 48, 577-587), since biosorbents different origins and structures can bind toxic metals with sometimes very high binding rates. Biosorbents are in in most cases cheap and easily accessible. Biosorbents are known materials that can be obtained from the biomass of moss, algae, fungi or bacteria, among others.
- biosorbents according to DE 197 184 52 AI are used.
- the biosorbents Before the radioactively contaminated eluates are brought into contact with the listed biosorbents by ion exchangers of any origin, the biosorbents must be brought to a suitable pH value for the binding of the radioactive metals and / or radionuclides.
- the pH range at which radioactive metals and / or radionuclides bind Biosorbents is carried out at pH values between 2.0 to 14, in particular between 4.0 and 8.0.
- the radioactive liquid sample is contacted with the biosorbent in two ways, either by the batch method or by the column method.
- This incinerator with a throughput of around 50 kg / hour consists of an incinerator, an afterburner and downstream systems for particle separation and flue gas scrubbing.
- a suction filter installed in the system keeps the entire incineration plant down to the feed system under negative pressure, so that no exhaust gases can leave the incineration plant and reach the environment unpurified before it is cleaned to remove radioactive particles and gases. After cleaning and analytical control, the exhaust gases are released into the environment via a chimney.
- the incinerator is charged automatically and discontinuously depending on the temperature and pressure conditions in the incinerators and the concentrations of oxygen added and the carbon monoxide or carbon dioxide formed in the flue gases during combustion.
- the ash residues accumulated after the combustion are automatically removed from the system and, according to the invention, fed to a further assembly by inclusion in glass powder, cement or bitumen.
- the biosorbents are burned in the oven at ⁇ 1100 ° C.
- the minimum temperature is 850 ° C and the minimum oxygen content is 6%.
- the small remaining residue after incineration is ash made of inorganic material, which gives only a negligible fraction of the volume of the radioactive biosorbents and much less of the liquid radioactive eluate solutions used to load the biosorbents. According to the process for reducing radioactive waste described so far, an unprecedented volume reduction effect on radioactive waste occurs.
- the inclusion products according to the invention produced for the intermediate or final storage according to the method according to the invention are easy to handle during transport and storage within the framework of the working guidelines applicable to radioactive waste, since they can be shaped and packaged according to their type of storage during the manufacturing process. In this way, they can be stored in a space-saving manner when fed to the intermediate or final storage facility.
- the previously low storage capacities for radioactive waste can thus be used much more effectively.
- the volume reduction effect of the radioactive waste produced according to the invention contributes significantly to a more economical intermediate or final storage of radioactive waste.
