Talk about what if something magically dissolves the concrete casks betrays that the person bringing that up has no idea what they're talking about. The wastes are not in any liquid or soluble form inside the casks. They're solid chunks of glass, like tektites, meteoric glass that's known to have sat in sea water unchanged for over a billion years.

Those interested in what is already there at Yucca Mountain should go to Google Earth. Search for "Sedan Crater." Scan south.

Guess what those 1000-ish craters are.
