The process of dismantling and finishing radioactive- infected equipment of kernel devices

The process can be used for dismantling kernel devices of different assignment, and also during their current and capital repairs, emergencies. The process allows to realize distant dismantling of radioactive-infected equipment, selection of its elements according to levels of radiation with their subsequent separate decontamination, parting of equipment on more small-sized parts with the purpose of their further compact storage, laser milling of surface segments with raised level of radiation. Distance monitoring between a nozzle slice of laser lens and a surface of workpiece is realize by measuring levels of radioactivity at different heights from a surface of workpiece, while the difference between heights during operation remains constant.
