Head Chyrko L.I., Registration Date 25-11-2011 Organization Scientific Center "Institute for Nuclear Research" of National Academy of Sciences of Ukraine popup.description2 It is shown, that for almost all units the base material of reactor vessel shells has lower radiative strengthening in comparison with weld metal. It may be explained by elevated nickel and manganeze content in weld metal, because both elements contributes radiative-stimulated processes owing to which ultra-fine clasters and precipitates, responsible for the strengthening of reactor vessel stels, form.
