Abstract:Several engineered disposal technologies involving concrete structures have been proposed for low-level radioactive waste disposal. The long-term performance and behavior of reinforced concrete structures in disposal units have been examined. Under most conditions, the reinforcing steel and concrete work well together to withstand the natural forces. Under certain conditions, however, the reinforcement and concrete may be subject to environmental attack which may cause degradation of the reinforced concrete. Water infiltration through the structure may increase as a result of cracking and increasing permeability and thereby increase the potential for contaminant release. The model for estimating time to onset of reinforcing steel corrosion due to presence of chloride is presented. Requirements for design of reinforced concrete structures for low-level radioactive waste disposal facilities are suggested.
