The Independent of the U.K., in an article entitled "The Explosive Truth Behind Fukushima's Meltdown," has reported mounting evidence indicating that earthquake damage in Daiichi Unit 1 was so severe that it was doomed to melt down even before the massive inundation from the tsunami knocked out emergency diesel generators, cutting off electricity to run vital cooling water pumps. The article reports:
"This means that assurances from the industry in Japan and overseas that the reactors were robust is now blown apart," said Shaun Burnie, an independent nuclear waste consultant who works with Greenpeace. "It raises fundamental questions on all reactors in high seismic risk areas."
As Mr Burnie points out, Tepco also admitted massive fuel melt 16 hours after loss of coolant, and seven or eight hours before the explosion in Unit One. "Since they must have known all this, their decision to flood with massive water volumes would guarantee massive additional contamination – including leaks to the ocean."
