All rights reserved.The nuclear physical properties of austenitic chromium-nickel steel EK-164 (Fe-16Cr-19Ni-2Mo-2Mn-Nb-Ti-B) and its manganese-based modifications EK-164Mn (Fe-16Cr-20Mn-2Mo-Nb-Ti-B) and EK-164MnW (Fe-16Cr-20Mn-2W-Nb-Ti-B) under irradiation (up to 5 effective years) in the neutron spectra of fast power (BN-600) and thermonuclear (DEMO-C) reactors and after irradiation (nuclear cooling up to 1000 years) were determined. The researches were performed on the basis of the ACDAM-2.0 calculation complex, taking into account the elemental (alloying and impurity) compositions of steels and typical neutron spectra of fission (BN-600) and fusion (DEMO-C) reactors. The entire set of nuclear physical characteristics of steels (primary radiation damage, transmutation of elements, radiogenic accumulation of elements, including hydrogen, helium and boron, γ-dose power, radioactivity, nuclear energy release, isotope contributions) is obtained and their comparative analysis is given. The time intervals for fulfilling the criteria of low activation of steels after irradiation (γ-dose rate less than 10 mSv/h, radioactivity less than 1010 Bq/kg, energy release less than 10 W/m3) were determined.
