I have a Brother-in-law that has spent the last 15 years helping to clean up the Hanford reservation in WA state from all of the radioactive wastes that were dumped there starting in the early days of WWII through the sixties. Parts of this place won't be really safe for a very long time and generations of engineers will work on this. Fukushima will be like this the cleanup will outlive our grandchildren. Yeah nukes are safe alright until you have another major accident. Broken windmills and solar panels are much easier to clean up than a Fukushima or a Chernobyl or a Three Mile Island. By the way some statisticians claim there is almost a certainty of a major nuclear power plant accident every 30-35 years.
