Dismantling of MR-Reactor IN-Vessel Setups

The results of dismantling performed on the in-vessel structures of the MR research reactor at National Research Center Kurchatov Institute are presented. Remote-controlled mechanisms and remote methods of diagnostics of the radiation conditions were used to perform the operations. These methods and technologies made it possible to provide radiation protection for the staff performing radiation-hazardous work and meet the dose-load requirements established in the regulatory documents. The results of dose-rate measurements in the work zones and the irradiation doses to personnel performing this type of work are presented.
