In the possibility that we have extreme weather events—and we are having them. We can't mention the term “climate change” around here, but in extreme weather events, it's maybe not unreasonable to assume....
Even this winter there has been a massive amount of snow. There may well be a pretty significant thaw very quickly, and you might have a flood.
If you had a flood in that area, how would it impact on the storage of this nuclear waste?
