MIC of Nuclear Waste Containers
Microbiologically influenced corrosion (MIC) is one of a number of threats to the long-term integrity of nuclear waste containers. As such, the potential for, and extent of, MIC must be assessed and suitable models developed for predicting the long-term behaviour of the canister. In general, there are two broad approaches to assessing the threat posed by MIC; first, to determine whether the environment will support microbial activity and, if so, where and when it will occur, or second, to estimate the maximum amount of damage that could occur if microbial activity in the repository is possible.
A decision tree approach is used to present evidence for both of these approaches and to decide whether MIC is an important threat to the integrity of the container. Examples are provided from various international nuclear waste management programs. Although the situation varies depending on the repository design, it is argued that MIC is less of a threat than other forms of corrosion and, from the viewpoint of the safety of the disposal system, MIC does not appear to greatly influence the overall dose consequence.
