Leaching Study in Process of Solidification of Radionuclide Co in Concrete
نویسندگان
چکیده
To assess the safety for disposal of radioactive waste-cement composition, the leaching of Co from a waste composite into a surrounding fluid has been studied. Leaching tests were carried out in accordance with a method recommended by IAEA. Determination of retardation factors, KF and coefficients of distribution, kd, using a simplified mathematical model for analyzing the migration of radionuclides, has been developed. Results presented in this paper are examples of results obtained in a 30 year mortar and concrete testing project, which will influence the design of the engineered trenches system for a future central radioactive waste disposal center.

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
متن کاملMODELING OF RAPID SOLIDIFICATION PROCESS IN THE GAS ATOMIZATION OF MOLTEN METALS
In the present work, a model was proposed to predict the thermal history during rapid solidification (RS) of metal droplets in the gas atomization process. The classical theory of heterogeneous nucleation was based on Newtonian heat flow and enthalpy method. Solving the governing numerical equations by the finite difference method (FDM) gave up the opportunity of analyzing the temperature-time ...
