The deactivation of reactor equipment during scheduled shutdowns and decommissioning is one of the actual problems of nuclear power engineering. The "dry" ion-plasma deactivation technology that we are developing to solve this problem and allows to avoid the formation of secondary liquid radioactive waste. In this paper, we calculate the sputtering yields and rates of ion sputtering of deposits in the oxides and spinels form for different ions of inert gases in order to select the most effective inert gas for deactivation. It was found that argon is the most effective for implementing our technology. Keywords: decommissioning, surface radioactive deposits, nuclear power plants, ion-thermal deactivation technology, reduction of secondary radioactive waste, reactor equipment.
