Abstract: A method for preparing to reload a fast nuclear reactor with heavy liquid metal coolant includes extracting a reactor plug and extracting a removable reactor block. The method includes installing handling equipment to form an unloading path under radiation safety conditions. The reactor plug is extracted from the reactor monoblock housing and transported to a plug shaft. The removable reactor block is extracted from the reactor monoblock housing and transported to a block shaft for later disassembly.

Abstract: A method of the plug and removable block extraction when reloading the nuclear reactor. The invention relates to nuclear engineering, in particular to a process of the plug and the removable block extraction from a fast reactor with a heavy liquid metal coolant. The technical result consists in extracting the plug and the removable block without fuel assemblies from the nuclear reactor using a complex of handling equipment under radiation safety conditions. The method of the plug removable block extraction involves preliminary installation of handling equipment, removing the plug from the reactor monoblock, as well as transportation and positioning of the plug in the plug shaft, unloading the removable block, its transportation and placing the removable block in the shaft for the removable block disassembly.
