CONCRETE AS AN ENGINEERED ALTERNATIVE TO SHALLOW LAND DISPOSAL OF LOW LEVEL NUCLEAR WASTE: OVERVIEW

This paper discusses the regulatory responsibilites governing low level radioactive wastes (LLW) disposal. It discusses the results of a research project to predict the service life of underground concrete for LLW applications. Assuming that disposal will be above the water table, the major degradation mechanisms affecting the concrete would be those due to sulfate attack, chloride ions, alkali-aggregate reaction and leaching. Mathematical modeling of the degradation mechanisms and the validation of those models with accelerated laboratory tests suggests that service lives of 500 years of concrete structures can be reliably achieved.
