Interaction of Hydrogen Isotopes with Ferritic-Martensitic Steel EK-181-Rusfer (Review of Results Obtained)

In this paper the results of the studies of reduced activation ferritic-martensitic steel EK-181 (Rusfer-EK-181, Fe–12 Cr–2 W–V–Ta–B) developed in Russia (Bochvar High-Technology Scientific Research Institute of Inorganic Materials—VNIINM) as a structural material for application as the core components of fast neutron, fusion, and hybrid reactors are summarized. Various aspects of hydrogen interaction with Rusfer steel, primarily retention, diffusion, and the effect of various defects on retention, are considered.
