Fukushima - A Global Threat That Requires a Global Response - 0 views

The story of Fukushima should be on the front pages of every newspaper. Instead, it is rarely mentioned. The problems at Fukushima are unprecedented in human experience and involve a high risk of radiation events larger than any that the global community has ever experienced. It is going to take the best engineering minds in the world to solve these problems and to diminish their global impact. When we researched the realities of Fukushima in preparation for this article, words like apocalyptic, cataclysmic and Earth-threatening came to mind. But, when we say such things, people react as if we were the little red hen screaming "the sky is falling" and the reports are ignored. So, we’re going to present what is known in this article and you can decide whether we are facing a potentially cataclysmic event.

There are three major problems at Fukushima: (1) Three reactor cores are missing; (2) Radiated water has been leaking from the plant in mass quantities for 2.5 years; and (3) Eleven thousand spent nuclear fuel rods, perhaps the most dangerous things ever created by humans, are stored at the plant and need to be removed, 1,533 of those are in a very precarious and dangerous position. Each of these three could result in dramatic radiation events, unlike any radiation exposure humans have ever experienced. We’ll discuss them in order, saving the most dangerous for last.

Missing reactor cores: Since the accident at Fukushima on March 11, 2011, three reactor cores have gone missing. There was an unprecedented three reactor ‘melt-down.’ These melted cores, called corium lavas, are thought to have passed through the basements of reactor buildings 1, 2 and 3, and to be somewhere in the ground underneath. Harvey Wasserman, who has been working on nuclear energy issues for over 40 years, tells us that during those four decades no one ever talked about the possibility of a multiple meltdown, but that is what occurred at Fukushima. It is an unprecedented situation to not know where these cores are. TEPCO is pouring water where they think the cores are, but they are not sure. There are occasional steam eruptions coming from the grounds of the reactors, so the cores are thought to still be hot. The concern is that the corium lavas will enter or may have already entered the aquifer below the plant. That would contaminate a much larger area with radioactive elements. Some suggest that it would require the area surrounding Tokyo, 40 million people, to be evacuated. Another concern is that if the corium lavas enter the aquifer, they could create a "super-heated pressurized steam reaction beneath a layer of caprock causing a major 'hydrovolcanic' explosion." A further concern is that a large reserve of groundwater which is coming in contact with the corium lavas is migrating towards the ocean at the rate of four meters per month. This could release greater amounts of radiation than were released in the early days of the disaster.

Excellent roundup of evidence that the Fukushima disaster recovery process has gone badly awry and is devolving quickly to looming further disasters. Political momentum is gathering to wrest the recovery efforts away from the Japanese government and to place its leadership in the hands of an international group of experts. The disaster was far worse than its portrayal in mainstream media, is continuing, and even worse secondary disasters now loom.
