Since my area of study is national security and not energy, basically I have opinions and not incites. However, other countries like France provide most of their basic national power grid through nuclear power, so they would seem to have a solution. I am guessing that the problem with waste in this country derives in large part from environmentalist roadblocks that have little to do with safety.
"the reason we can't reprocess the waste is that the President of the United States won't rescind an Executive Order. The reason for the order has nothing to do with technology or safety; it's about who gets to make money. The holders of treasury bonds [OPEC] need a reason to buy them with the Fed inflating the currency and this is how our government delivers to those bond holders while hiding the inflation from the public."
