> > With the zeroing of the budget for Yucca Mountain nuclear waste repository in Nevada, more nuclear waste is being loaded into sealed metal casks filled with inert gas. Many of these casks will be stored in coastal or lakeside regions where a salt air environment exists, and the Massachusetts Institute of Technology is studying how such dry casks perform in salt environments. Some hope that the casks can be used for 100 years, but cracking related to corrosion could occur in 30 years or less.

> In other words the "safe" temporary storage is not really safe.

I think you misunderstood this paragraph. The waste is being stored in these temporary casks because the Yucca Mountain facility's budget was eliminated, and thus temporary storage is the only storage option.
