摘要： Garments contaminated with radioactive, toxin, biological and/or chemical contaminants are deposited in a cleaning drum and the drum is agitated during a wash cycle. A dry cleaning solvent is added to the drum during the initial wash cycle and then drained to a distillation means. Within the distillation means, there is a neutralizing agent which deactivates the biological and toxin contaminants and chemically breaks down the chemical contaminants removed with the dry cleaning solvent from the cleaning drum. Dry cleaning solvent is then continuously added to the drum during the secondary wash cycle and continuously removed from the drum. After the dry cleaning solvent is removed from the drum, and before it is pumped back to the drum, the dry cleaning solvent is filtered to remove remaining trace particulate contaminants. The dry cleaning solvent is also passed through an absorber where remaining trace chemical contaminants dissolves in the dry cleaning solvent are removed. The garments are then rinsed by circulating contaminant free dry cleaning solvent through the drum. After rinsing, the garments are dried by circulating hot, unsaturated dry cleaning solvent vapor through the drum.

摘要： In an installation comprising a solvent regeneration circuit and a solvent recovery circuit, each solvent container is connected independently to the boiler of a distillation unit for cleaning purposes. The relative arrangement of the solvent containers is such that the solvent circulates under the action of gravity from a condenser to the boiler and from each container to the boiler. The boiler is removable for subsequent disposal after filling with solvent residues and waste materials.

摘要： Garments are deposited in a cleaning drum and the drum is agitated during a wash cycle. A dry cleaning solvent is continuously added to the drum during the wash cycle and continuously removed from the drum during the wash cycle to flush the radioactive particulate material separated from the garments into a sump. The solvent is pumped from the sump for addition to the drum during the wash cycle and the pumped solvent is filtered to remove substantially all of the radioactive particulate material suspended in the solvent.The apparatus for decontaminating the radioactive garments comprises a sump for supporting a dry cleaning solvent. A drum for supporting the radioactively contaminated garments during a wash cycle which separates the radioactive particulate material from the garments means are provided for continuously pumping the dry cleaning solvent from the sump to the drum and for continuously removing the solvent and separated particulate material from the drum into the sump. A filtering means is used to continuously remove substantially all of the particulate material suspended in the solvent that is carried to the drum.

摘要： Disclosed herein is a nuclear power plant main steam system that reduces the atmospheric discharge of radioactive materials generated in an accident. The system includes: a decontamination water tank containing decontamination water; and a connection pipe for connecting the decontamination water tank to a main steam pipe which connects a steam generator and a turbine. A main steam safety valve or a connection valve is provided as a three-way valve configured to discharge the generated steam to the atmosphere when an accident occurs within a design basis and to transfer the generated steam to the decontamination water tank when an accident involving damage to nuclear fuel occurs. The main steam system reduces discharge of radioactive materials to the atmosphere when a containment bypass accident (e.g., a steam generator tube rupture caused by high-temperature steam) occurs.

摘要： The invention is intended for integrated decontamination of soils contaminated with mercury (amalgam) or/and radionuclides. Method for soil decontamination includes preparation of pulp by mixing soils with water at the soil sampling point with separation of fraction with fragments more than 100 mm in the pulp preparation module, disintegration of pulp and soil aggregates in the disintegration module with separation of plants residues and fraction with fragments more than 10 mm. Pulp thickening. In the hydroclassification module the pulp is separated into sand and fine particle fractions, the fine particle fraction goes to the dehydration module, designed as a concentrator, where it is thickened and dehydrated for further disposal. If mercury and amalgam are present in soils they are separated in the thickening module. Technical result—implementation of a low-waste nonchemical technology for decontamination of soil from mercury, its water-insoluble forms, amalgam or/and radionuclides in a single technological process without equipment resetting, separation of metal mercury or its amalgam.

摘要： An electrostatic induction system includes used activated carbon as electron-collecting units, to which electrons are supplied by an electrostatic induction apparatus so that impurities that have been absorbed by activated carbon are neutralized or reduced, and neutralized or reduced used activated carbon is acquired. The neutralized or reduced used activated carbon is buried in an environmental conservation implementation area in such a manner that an amount of the buried neutralized or reduced used activated carbon and a number of locations at which the neutralized or reduced used activated carbon are buried are adjusted depending on a property of the environmental conservation implementation area, and that the buried neutralized or reduced used activated carbon gradually decrease an earthing resistance of the environmental conservation implementation area so as to cause the earthing resistance to have a value less than or equal to 10Ω.

摘要： A cobalt coincidence radioactivity detector is used to separate radioactive concrete dust from uncontaminated dust resulting from dismantling a nuclear power plant. A suction air stream carries the dust through a vacuum line to a cyclone segregator. The dust falls into a smaller first container from the segregator, and the detector detects radioactivity in the filled first container. The dust is transferred from the first container to a second container if the detected radioactivity exceeds a predetermined threshold. The dust is transferred from the first container to a third container if the detected radioactivity does not exceed the predetermined threshold. A filter collects the dust carried past the segregator by the suction air stream. If the radioactivity detected in the dust that collects on the filter exceeds the predetermined threshold, the dust in the first container is transferred to the second container before the first container is allowed to fill.
