ESTIMATION OF U, Pu, Np, Am, Cs AND Tc DISTRIBUTION COEFFICIENTS IN CRYSTALLINE ROCKS OF POTENTIAL AREAS FOR DEEP GEOLOGICAL REPOSITORY IN UKRAINE
Abstract
The results of estimation of U, Pu, Np, Am, Cs and Tc distribution coefficients in crystalline rocks of potential areas for deep geological repository in Ukraine are presented. Mean distribution coefficients calculated on the basis of published experimental data obtained under similar to potential conditions of future GR in Ukraine conditions increased in sequence Tc-oxi <Np (V) <U (VI) <Pu-oxi <Tc-red <Cs <U (IV) <Pu-red <Np (IV) <Am. In conditions typical for potential area placement of the GR in Ukraine, neptunium is weak and medium, uranium and cesium are medium and low, and americium and plutonium are strongly sorbing radionuclides.
