And you may be right. I don't pretend to have all the answers. I just have a little more hope because I've seen similar situations with large contaminated abandoned factory complexes work out, or at least get a little better.
Honestly, the only private application for Hanford that came to mind for me was a new nuclear power site, but I that would be a tough political battle. But, if a new nuclear reactor is ever built in this country it makes sense to do it in a place like Hanford that's already contaminated, than risk contaminating a virgin location. Further, the risks, environmental safety controls, personnel training, etc. would all be similar; there's already an active nuclear power facility there, there's established infrastructure to build from; and the place is crawling with gov't officials to keep an eye on things.
