Abstract

Language:

This study presents an optimization of mortar, enhanced with bentonite clay, utilized for the immobilization of radionuclides such as 60Co, 137Cs, 85Sr, and 54Mn. A straightforward mathematical model is developed, enabling the minimization of the leach rate and permeability, while maximizing compressive strength. Based on experimental data, an optimal solution was identified, which will inform future strategies for a Serbian radioactive waste disposal center. The framework of the study emphasizes the importance of conditioning radioactive waste to ensure that the resulting material is leach-resistant and mechanically stable for safe handling, transport, and disposal. The research highlights key physicochemical characteristics including compressive strength and permeability, which are critical for the effective management of intermediate level wastes in concrete arrangements. The results indicate that careful selection and optimization of permeable materials can significantly enhance the integrity and safety of radioactive waste containment systems.
