‘Beyond the Cloud’ Yanaoshi 3.11, June 3, 2013 – French nuclear engineer Gérard Aleton (at 3:30 in): When a nuclear power plant is built [...] workers can access all building parts, including the tank — But dismantling is another story. […] There’s no longer a conventional access to those parts of the building. No human can enter those tanks and radioactive areas. We then must use teleoperation, or robotic equipment. I’m not even talking about damaged power plants. Those are so problematic, and heavy to handle that I do not think we know how to treat them today. To address this issue would take 50 years, or maybe one century. And the living proof today is Chernobyl. It is still buried under concrete which now starts leaking. There is the need to pour more concrete to seal it, and we still cannot access the melted core.
RTE News, March 14, 2013 – Nuclear expert John Large (at 24:30 in): As for the reactors themselves, they will have to be closed down and sealed up. More likely, what’s left of the reactors will be left in situ for 100 years or more, until there’s enough radioactive decay to allow individuals to get in there to clean up the mess. […] For example in the UK the closed down reactors that haven’t gone through accidents are left in situ for 100 years after they’re closed down, before they are fully decommissioned.
