The invention provides an operating device for electrolytic decontamination of radioactively contaminated metals on the surface, including: a crane, which is sequentially provided with a contaminated sample table, a first ultrasonic cleaning device, a radioactivity / size measuring instrument, and an electrolytic decontamination device within the range of the crane. The tank, the second ultrasonic cleaning device, the radioactivity measuring instrument and the sample stage after decontamination, the titanium fixture is fixed on the crane, and the titanium fixture can be moved to the above parts through the crane slideway; the power supply system, whose anode is connected to the titanium fixture, passes through the titanium fixture Clamp the contaminated sample so that the contaminated sample becomes an anode during the electrolytic decontamination process, and the cathode is connected to the electrolytic decontamination tank; the crane system is used to control the crane to realize the movement of the titanium fixture up and down, left and right, as well as the clamping and releasing process of the sample . The device provided by the invention realizes the cleaning, radioactivity measurement, size measurement, and electrolytic decontamination of contaminated samples through the fixture equipped with the crane, realizes remote operation, protects the health of personnel, and can realize continuous operation and improve efficiency.
Description
technical field [0001] The invention belongs to the technical field of radioactive waste treatment in the nuclear industry, and in particular relates to an operating device for electrolytic decontamination of surface radioactively contaminated metals. Background technique [0002] The surface of some waste equipment produced in the operation and production process of nuclear power plants and nuclear-related scientific research units will be contaminated by radioactivity to varying degrees. For equipment contaminated by radioactivity, it must undergo strict decontamination treatment and control to prevent contaminated waste metal from flowing into society , affecting public safety. [0003] The decontamination methods for radioactively contaminated devices mainly include mechanical-physical methods, chemical methods, melting methods, biological methods, and electrochemical methods. When selecting decontamination methods, it is necessary to comprehensively consider the applica...
