Popis: The results of the dismantling of the active drain system and the decontamination of technological enclosures of the loop installations of the MR reactor, which is being decommissioned at the NRC Kurchatov Institute, are presented. The radioactive contamination of the pipelines of the system and the soil had a complex nuclide composition. Methods for assessing the volume of radioactive waste being removed from the premises are discussed, and criteria for the radioactive contamination of individual building structures and the soil to reach the conditions of the final state of the object as determined by the plan of operations are presented. Remote-controlled machines and dust suppression technologies are used to reduce the effect of the radiation fields on the workers, to protect the workers as they perform their jobs, and to increase the power availability of per worker in the process of dismantling and handling radioactive waste. As a result, criteria for the radiation situation corresponding to the working conditions of level-B personnel were reached. This corresponds to the parameters of the final state of a facility as prescribed by the plan for decommissioning the MP and RFT reactors.
