One of the question that arised after Fukushima was if we were good enough from a technical POV to handle nuclear power in a safe way. Not speaking only about the cost it takes to do things The Right Way, but also the education of your staff, handling of operational errors, covering of the unavoidable design and material deffects, and so on... For e.g. launching rockets to space can still fail from times to times, despite the effort and care it takes to do it. Crashing planes also occur from times to times, despite our extensive knowledge of the field and all the effort we can put in preventing disasters. Wouldn't it be sane to assume that nuclear power will also fail from times to times, and you can't do much about it?
