Comparing Fukushima nuclear meltdown to the Chernobyl one

Fukushima Meltdowns: A Global Conspiracy of Denial By William Boardman Global Research, Reader Supported News January 05, 2014 “…….Chernobyl 1986 and Fukushima 2011 are not really comparable Chernobyl is the closest precedent to Fukushima, and it’s not very close. Chernobyl at the time of the 1986 electric failure and explosion had four operating reactors and two more under construction. The Chernobyl accident involved one reactor meltdown. Other reactors kept operating for some time after the accident. The rector meltdown was eventually entombed, containing the meltdown and reducing the risk. Until Fukushima, Chernobyl was considered the worst nuclear power accident in history, and it is still far from over (albeit largely contained for the time being). The Chernobyl Exclusion Zone of roughly 1,000 square miles remains one of the most radioactive areas in the world and the clean-up is not even expected to be complete before 2065.

At the time of the March 11, 2011, earthquake and tsunami, the Fukushima plant had six operating reactors. Three of them went into meltdown and a fourth was left with a heavily laden fuel pool teetering a hundred feet above the ground. Two other reactors were undamaged and have been shut down. Radiation levels remain lethal in each of the melted-down reactors, where the meltdowns appear to be held in check by water that is pumped into the reactors to keep them cool. In the process, the water gets irradiated and that which is not collected on site in leaking tanks flows steadily into the Pacific Ocean. Within the first two weeks, Fukushima radiation was comparable to Chernobyl’s and while the levels have gone down, they remain elevated.

The plant’s corporate owner, Tokyo Electric Power Company (TEPCO), in turn effectively owned by the Japanese government after a2012 nationalization, began removing more than 1,500 fuel rod assemblies from the teetering fuel pool in November, a delicate process expected to take a year or more. There are additional fuel pools attached to each of the melted down reactors and a much larger general fuel pool, all of which contain nuclear fuel rod assemblies that are secure only as long as TEPCO continues to cool them. The Fukushima Exclusion Zone, a 12-mile radius around the nuclear plant, is about 500 square miles (much of it ocean); little specific information about the exclusion zone is easily available, but media coverage in the form of disaster tourism is plentiful, including a Google Street View interactive display.

Despite their significant differences as disasters, Chernobyl and Fukushima are both rated at 7 – a “major accident” on the International Nuclear Event Scale designed in 1990 by the International Atomic Energy Agency (IAEA). That is the highest rating on the scale, a reflection of the inherent denial that colors most official nuclear thinking. Designed by nuclear “experts” after Chernobyl, the scale can’t imagine a worse accident than Chernobyl which, for all its intensity, was effectively over as an accident in a relatively short period of time. At Fukushima, by contrast, the initial set of events was less acute than Chernobyl, but almost three years later they continue without any resolution likely soon. Additionally Fukushima has three reactor meltdowns and thousands of precarious fuel rod assemblies in uncertain pools, any of which could produce a new crisis that would put Fukushima clearly off the scale.

And then there’s groundwater. Groundwater was not a problem at Chernobyl. Groundwater is a huge problem at the Fukushima plant that was built at the seashore, on a former riverbed, over an active aquifer. In a short video, nuclear engineer Arnie Gunderson makes clear why groundwater makes Fukushima so hard to clean up, and why radiation levels there will likely remain dangerous for another hundred years……..http://www.globalresearch.ca/fukushima-meltdowns-a-global-conspiracy-of-denial/5363827
