Abstract

Study of sorption behavior of radionuclides toward five rock samples drilled in the deep-well R12 in the exocontact zone of Nizhnekansky granitoid massif (“Eniseysky” area) in the range of depth 166 m – 476 m was carried out. The sorption kinetics and Kd values of the long-lived radionuclides of different chemical behavior 137Cs, 226Ra, 79Se, 237+239Np, 239,240Pu, 241,243Am were determined. Experiments were performed under the conditions that are relevant for the future high level waste disposal (atmosphere; composition, pH and Eh of the solutions). Digital radiography demonstrated heterogeneous sorption of all the investigated radionuclides and revealed phases with higher sorption ability. It was established that sorption of metal cations is fast and reaches steady state in a few hours while Se in the form of selenate-ion sorbs insignificantly.
