Modelling the Long Term Evolution of Radioactive Waste Disposal Environments

Abstract

The design, development and use of a computer model to simulate the long-term evolution of radioactive waste disposal environments is discussed. The model, TIME2, has been developed for use within a probabilistic risk assessment framework in the evaluation of potential shallow land burial sites by the UK Department of the Environment. This paper outlines the processes modelled by TIME2, the operation of the code and some example results. Use of the code in risk assessment is discussed and planned future developments are outlined.
