放射性要素の除染装置

Japanese Patent JP7202402

B2

The invention relates to devices for eliminating radioactive contamination of radioactive waste, namely, the radioactive waste surface decontamination facility. The object of the claimed invention is to extend the facility capabilities and reduce harmful factors. The technical result achieved by the current invention is to reduce the amount of waste, as well as to minimize harmful factors and dose loads. The specified technical result is achieved due to the fact that the radioactive elements decontamination device comprises the loading-unloading manipulator, the process chamber with a lid with the round turn-around table located inside, the waste disposal container and the exhaust ventilation unit, while the process chamber is equipped with the remote handling unit mounted on its outer part, the device for a dust-free abrasive blast cleaning, waterjet cutting unit, connected through a leak-tight installed hoses in the process chamber walls, the abrasive and slurry collection unit and at least one device for radiation control, located inside the process chamber, the solid and liquid waste separation unit and discharge liquid waste, wherein the process chamber is equipped with chemical-radiation-shock proof sound-absorbing coating, and the remote control unit connected with the device for a dust-free abrasive blast cleaning, waterjet cutting unit, abrasive and slurry collection device, exhaust ventilation unit, the process chamber lid, the radiation control unit and the solid and liquid waste separation unit. Preferably, the process chamber may be equipped with light openings located in its side walls, and the floor of the process chamber is made with a slope of 0.6° to ensure the flow of spent hydroabrasive mixtures. The process chamber may be equipped with auxiliary leak-tight sealed swing doors and equipped with the intake exhaust ventilation. The abrasive and slurry collection unit preferably comprises a control panel, a vacuum dust collector, a connected with it container for collecting spent fine waste fractions, a mobile cyclone separator, a container connected with it for collecting spent large waste fractions, comprising a fill level monitoring sensor, a leak monitoring sensor installed on a mobile cyclone separator. The exhaust ventilation unit may be equipped with a leak-tight mounted flange valve and a discharge sensor. The solid and liquid waste separation unit preferably comprises a precipitator tank with an overflow tube and sensors of the lower and upper levels, leak-tightly connected by means of an adapter with a container for collecting waste, a tilter for liquid waste draining, a hydrocyclone, at least one pump and a pipeline system connecting them.
