摘要： The invention relates to the field of water purification. The present method for purifying water of radionuclides by nuclear transmutation involves preparing a culture medium for the growth of microbiological cultures, adding a biomass of microorganisms to said medium, holding the biomass of microorganisms in an aqueous solution undergoing purification for from 10 hours for aerobic microorganisms to 24 hours for anaerobic microorganisms, and adding key trace elements and/or combinations thereof to different parts of the resultant aqueous solution. The aqueous solution undergoing purification is held for the purpose of selecting the trace elements and/or combinations thereof necessary to speed up the process of transmutation, and the selected trace elements and/or combinations thereof are added to the aqueous solution undergoing purification. The aqueous solution undergoing purification is held for the time necessary to achieve the required residual radioactivity value, and the biomass of microorganisms is removed from the aqueous solution undergoing purification.

摘要： A process for selectively separating a metallic constituent from other metals and other materials accompanying the metallic constituent in a mixture is described. The process comprises the step of providing the mixture in an aqueous solution such that the metallic constituent forms a complex anion in the solution. One or more of the other metals forms a cation or a complex cation in the solution. Another step includes contacting the solution with one or more additives to form layered double hydroxide (LDH) material in situ such that the complex anion is intercalated within interlayers of the LDH material and wherein one or more of the other metals are incorporated into the LDH material's crystal structure or matrix. Another step involves the addition of an LDH to an aqueous solution. The process involves selectively recovering the metallic constituent from the interlayer of the LDH by subjecting the LDH to a recovery treatment step(s) and as required, methods to modify the LDH to facilitate metal separation and recovery or contaminant stabilisation.

摘要： [Problem to be Solved]
To provide a decontamination method and system for soil and the like for decontaminating soil of, for example, fields, and water contaminated with radioactive materials reliably and rapidly on site, aiming to perform decontamination with precision and improved efficiency. According to the present invention, the decontaminated soil is improved by adding soil activators, and then the improved soil is returned to the original field readily to promote the restart of farming. Further, according to the present invention, the radioactive materials adhering to or deposited on the soil are separated from the soil and then concentrated precisely. According to the invention, a reduction in the volume of the contaminated soil and a safe treatment of the radioactive materials are achieved. Further, according to the invention, decontamination of radioactive cesium and tritium is achieved, thereby relieving anxiety of internal exposure to the radiation of tritium. Further, the decontamination apparatus can be disposed of efficiently and safely.
[Solving Means]
An object to be decontaminated contaminated with radioactive material is introduced into the eluting solvent 49 and dissolved, and the radioactive material is separated from the eluting solvent 49. The object to be decontaminated includes the contaminated soil 17 and the contaminated water 4. One or both of them are collected and introduced into the eluting solvent 49. The radioactive materials dissolved into the eluting solvent 49 and the object area to be decontaminated are separated into solid and liquid. The soil 17a after solid-liquid separation and from which the radioactive material is removed is collected, and the eluting solvent after solid-liquid separation and a separated liquid 37 containing contaminated water are introduced into the electrolysis tank 13 and electrolyzed. The decontamination method for soil and the like includes depositing metal ions such as the radioactive materials on the cathode 31. Hydrogen containing tritium generated in electrolysis is collected in the electrolysis tank 13. The hydrogen is moved to the outside of the electrolysis tank 13 and trapped.

摘要： A system (100) and a method for capturing gaseous, particulate and liquid radioactive material released from primary containment (3) of a Light Water Reactor (LWR) during severe accident conditions. The system includes a below-grade media area (4), connected to a reactor pressure vessel (RPV) and portions of primary containment (3), providing varying levels of adsorption / absorption of the radioactive material. The media area (4) is located on-site to offer a passive, self-regulating structure for stabilizing a nuclear reactor. The capture system provides for liquid drainage and gaseous venting of the radioactive material, and a treatment capable of treating the media following stabilization of the reactor.
