Description

To assess the safety for disposal of radioactive mortar-waste composition, the leaching of 137Cs from waste composite into a surrounding fluid has been studied. leaching tests were carried out in accordance with a method recommended by the IAEA. determination of retardation factors, KF, and coefficients of distribution, kd using simplified mathematical model for analyzing the migration of radionuclides has been developed. In our experiment we have achieved the lowest leaching values after 60 days in samples. Results presented in this paper are examples of results obtained in a 20 year mortar and concrete testing project, which will influence the design of the engineered trenches for a future central Serbian radioactive waste storage center.
