Abstract

Sorption and phase distribution of activation products (65Zn, 54Mn, 59Fe, 60Со) in systems consisting of Pb–Bi melt and a porous material were studied under laboratory conditions. Radionuclides of elements with minimal oxygen affinity (Ru, Te, and Sb) remain predominantly in the coolant melt and are weakly sorbed by the solid phase. Radionuclides with higher oxygen affinity are well sorbed by structural solid sorbents. The maximum of the 60Со sorption onto porous steel is reached at 853 K.
