Abstract

The review presents currently available data on the processes occurring during irradiation of reduced activation ferritic/martensitic steels with low-energy (≤200 eV) deuterium plasma. The mechanisms of formation of rough nanosized structures on the surface of steels, which affect the sputtering yields of these steels, are considered. The parameters of the transfer of hydrogen isotopes in these steels, obtained from experiments on gas permeability and plasma irradiation of hydrogen isotopes, have been collected. The results of studies on the accumulation of deuterium in steels without and containing radiation-induced defects are discussed.
