Reactor decommissioning is one of the nuclear facility decommissioning work that needs to be focused on.In this paper,the overall situation of global reactor decommissioning is analyzed.The concept of decommissioning technology in a broad sense is put forward,and a reactor decommissioning technology system consisting of decommissioning management and overall technology,decommissioning special technology and common support technology is constructed.The policies,regulations and standards,technical route,project management and other decommissioning management and overall technology are discussed.The special decommissioning technologies such as safe shutdown,characteristic investigation,decontamination,cutting and dismantling,waste management and final decommissioning management are analyzed.The common supporting technologies such as digitization and intellectualization,radiation protection and monitoring are discussed.After comprehensive analysis and demonstration,the development direction of specific decommissioning technology and the development trend of reactor decommissioning technology in the future are prospected.
