CLAB: a subsurface storage facility
There are many countries that store spent fuels and high-level waste. What is different about this Swedish storage facility, CLAB, is that it is not very deep. Spent fuel is stored here under water. There is extensive monitoring of the items being stored, which are expected to be here for around thirty years at most. With storage for much longer periods, the issue arises of how to maintain the condition of the storage facilities. Moreover it is not always possible to count on the same standard of monitoring.
