dc.description.abstract© 2022The paper presents the investigation results using TEM and SEM methods of alloy 42XNM after irradiation as a part of the absorbing element (the control rod cladding) of the VVER-1000 reactor control system (to the damaging dose of ∼ 12 dpa at a temperature of ∼ 350 °C) and after isothermal annealing in the temperature range of (500–1100)°C simulating LOCA-parameters and corresponding to a sharp decrease in plastic properties. It was shown that during such annealing, a change in the alloy's phase composition and porosity evolution was observed, dislocation loops and grain boundary segregations were completely annealed. The probable reasons for the decrease in the plasticity of the 42XNM alloy in the specified temperature range were found: the formation of α-Cr particles along grain boundaries and the pore formation on interfacial and grain boundaries.
