Influence of the segregation of the granulate from the radwaste-mortar mixture from on the {sup 137}Cs leach-rate; Uticaj segregacije granulata iz sastava betonske - RAO forme na izluzivanje Cs{sup 137}

Abstract

In this paper. influence of the segregation of the granulate, presented in the radwaste-mortar matrix formulation, on the {sup 137}Cs, immobilized in the waste form, leach-rate is presented. {sup 137}Cs leach-rates of the two inspected groups of the radwaste-mortar mixture samples were compared, where the first group of the orthocylinder shaped samples was treated due to the Standard Hespe's method and the second group was treated using modified Hespe's method. In the prolonged experimental time, both groups have obtained leach-rate values that are nearly the same, striving to the saturation leach-rate values. This fact indicates that the leaching of the radionuclide as a consequence of the granulate segregation process is in same way rebuilt, as a result of the completed hydratation of the mortar matrix, and 'self healing' of the new open pores and cavities (author)
