doom writes "Ian Sample at the Guardian UK does a really thorough write-up of what's going on with the Fukushima Clean-up. From the article: 'Though delicate and painstaking, retrieving the fuel rod assemblies from the pools is not the toughest job the workers face. More challenging by far will be digging out the molten cores in the reactors themselves. Some of the fuel burned through its primary containment and is now mixed with cladding, steel and concrete. The mixture will have to be broken up, sealed in steel containers and moved to a nuclear waste storage site. That work will not start until some time after 2020.'"
