Much of that high cost is because the waste is treated so delicately, while equally deadly non-nuclear waste is treated with much less care.
I imagine there have been a lot of places in your country (as with any industrialized country) that have been horribly contaminated with non-nuclear pollution, then cleaned up. While these events can certainly be used as an argument for taking more care, they're almost never used as an argument to give up on the whole idea of industry.
Nuclear waste is bad, but it doesn't seem to be on the level of "we must lock this up so securely that God Himself cannot access it" as people seem to try for.
