About 10 years ago I was on holiday in Scotland. Dounreay had already been dismantled but they had a visitor's centre open. We dropped in to look around and have a cup of tea. By the time I left, I was incredibly angry and convinced that nuclear power in it's current form is a really bad idea.
I wasn't angry with the staff at the visitor's centre; I was angry with the people who'd worked at Dounreay in the past. It was primarily a research site. The research produced a certain amount of high level waste. Now they could have disposed of it in some sort of thoughtful manner but instead they used "The Hole".
Dounreay is perched on a sea cliff. At some point, they'd drilled a shaft down to sea level and tunneled out to sea so they could get lots of nice cold sea water. The shaft is about 65m deep. They didn't need it any more so they blocked off the tunnel to the sea. Then someone thought, how about we just chuck stuff in this nice hole we have?
They didn't keep any records of what went in. They didn't pack the material in any sort of fashion. They didn't stop the highly reactive metals from meeting the corrosive sea water. Eventually the hole filled up. What to do? The answer was to drop a massive concrete block on the stuff in the hole to compact it. That worked a treat. They threw more stuff in.
One day the shaft blew up.
So now, the clean up job consists of trying to remove mangled pieces of highly radioactive material from a 65m shaft without triggering another hydrogen explosion or creating a nuclear reaction. That's the job that going to take decades.
So that's why I'm angry. There's nothing wrong with nuclear power itself. The problem is that you have pointy-haired managers and scientists who are dying of curiosity in charge of it. These people have to handle tons of material that must be accounted for with milligram precision. It's a recipe for disaster. If we can create nuclear reactors that don't need this level of care and attention then I'll be all for it.
