the_newsbeagle writes "In Japan, workers have spent nearly three years on the clean-up and decommissioning of the ruined Fukushima Daiichi nuclear power station. They only have 37 years to go. Taking apart the plant's three melted-down reactors is expected to take 40 years and cost $15 billion. The plant's owner, TEPCO, admits that its engineers don't yet know how they'll pull off this monumental task. An in-depth examination of the decommissioning process explains the challenges, such as working amid the radioactive rubble, stopping up the leaks that spill radioactive water throughout the site, and handling the blobs of melted nuclear fuel. Many of the tasks will be accomplished by newly invented robots that can go where humans fear to tread."
