Abstract: The features of tritium adsorption by clay rocks, which mainly consist of clay minerals with high adsorption abilities for tritium oxide (НTO) and super heavy water (T₂O), were studied after their thermal treatment at a temperature of 105 and 500 °C. The observation was carried out in a closed system "tritiated water - clay rock". Indicators of the dynamics of growth of tritium adsorption by heat-treated clay rocks over 380 days are obtained. It was found that the adsorption of tritium in this observation system actively grows for the first 30 - 40 days for all the studied minerals, and then slows down. White clays retain an increase in adsorption over the entire observation period of 380 days.

Keywords: tritiated water, pore water, adsorption water, heat treatment, hydraulic permeability.
