The radioactive core in a reactor at the crippled Fukushima nuclear power plant appears to have melted through the bottom of its containment vessel and on to a concrete floor, experts say, raising fears of a major release of radiation at the site. The warning follows an analysis by a leading US expert of radiation levels at the plant….
Richard Lahey, who was head of safety research for boiling-water reactors at General Electric when the company installed the units at Fukushima, told the Guardian workers at the site appeared to have "lost the race" to save the reactor…" ("Japan may have lost race to save nuclear reactor", The Guardian)
Levels of radiation in the ocean next to the Fukushima Daiichi nuclear power plant have surged to record highs, the government said Wednesday, as operators try to deal with large amounts of radioactive water—the unwanted byproduct of operations to cool the reactors.
The Nuclear and Industrial Safety Agency said water taken Tuesday afternoon from the monitoring location for the troubled reactors Nos. 1 to 4 had 3,355 times the permitted concentration of iodine-131. That is the highest yet recorded at the sampling location, which is 330 meters south of the reactors’ discharge outlet." ("Seawater Radiation Level Soars Near Plant", Wall Street Journal)
The health effects of the Chernobyl accident are massive and demonstrable. They have been studied by many research groups in Russia, Belarus and the Ukraine, in the USA, Greece, Germany, Sweden, Switzerland and Japan. The scientific peer reviewed literature is enormous. Hundreds of papers report the effects, increases in cancer and a range of other diseases. My colleague Alexey Yablokov of the Russian Academy of Sciences, published a review of these studies in the Annals of the New York Academy of Sciences (2009). Earlier in 2006 he and I collected together reviews of the Russian literature by a group of eminent radiation scientists and published these in the book Chernobyl, 20 Years After. The result: more than a million people have died between 1986 and 2004 as a direct result of Chernobyl.
Since the official International Atomic Energy Agency (IAEA) figures for the Fukushima contamination are from 200 to 900kBq.sq metre out to 78km from the site, we can expect between 22 per cent and 90 per cent increases in cancer in people living in these places in the next 10 years.
The legacy of latent radiogenic diseases from hydrogen bomb testing in the Marshall Islands provides some clues about what ill-health mysteries await the affected Japanese in the decades ahead…..Traces of I-131 have been discovered in Tokyo drinking water and in seawater offshore from the reactors. It took nine years for the first thyroid tumor to appear among the exposed Marshallese and hypothyroidism and cancer continued to appear decades later……
Plutonium-239 has a half life of 24,000 years, is considered one of the most toxic substances on Earth, and if absorbed is a potent alpha emitter that can induce cancer. This isotope too is found in the soils and groundwater of the downwind atolls from the Bikini and Enewetak H-bomb tests…
Radioactive Iodine-129 with a half-life of 15 million years and a well-documented capacity to bioaccumulate in the foodchain, will also remain as a persistent problem for the affected Japanese…
The sociocultural and psychological effects [e.g., PTSD] of the Fukushima nuclear disaster will be long-lasting, given the uncertainty surrounding the contamination of their prefecture and beyond." ("Radiation, Japan and the Marshall Islands; Living and dying downwind", Glenn Alcalay, Counterpunch)
In the wake of the continuing nuclear tragedy in Japan, the United States government is still moving quickly to increase the amounts of radiation the population can ‘safely’ absorb by raising the safe zone for exposure to levels designed to protect the government and nuclear industry more than human life. It’s all about cutting costs now as the infinite-growth paradigm sputters and moves towards extinction. As has been demonstrated by government conduct in the Gulf of Mexico in the wake of Deepwater Horizon and in Japan, life has taken a back seat to cost-cutting and public relations posturing. The game plan now appears to be to protect government and the nuclear industry from “excessive costs”… at any cost." (Washington’s Blog)
Today, tens of thousands of tons of irradiated fuel sits in spent fuel pools across America. At many sites, there is nearly ten times as much irradiated fuel in the spent fuel pools as in the reactor cores. The spent fuel pools are not cooled by an array of highly reliable emergency cooling systems capable of being powered from the grid, diesel generators, or batteries. Instead, the pools are cooled by one regular system sometimes backed up by an alternate makeup system.
The spent fuel pools are not housed within robust concrete containment structures designed to protect the public from the radioactivity released from damaged irradiated fuel. Instead, the pools are often housed in buildings with sheet metal siding like that in a Sears storage shed. I have nothing against the quality or utility of Sears’ storage sheds, but they are not suitable for nuclear waste storage.
The irrefutable bottom line is that we have utterly failed to properly manage the risk from irradiated fuel stored at our nation’s nuclear power plants. We can and must do better." (The Union of Concerned Scientists.)
Nuclear energy is a ticking-timebomb. There are safer ways to keep the lights on.

Update: Watch this video by Arnie Gundersen at Fairewinds Associates, Inc. "Recent press reports have discussed the possibility that Fukushima Unit 1 may be having a nuclear chain reaction. New data released by TEPCO indicates that even though Fukushima Unit 1 was shut down during the March 11 earthquake, it appears to have "gone critical" again without human intervention. The detection by TEPCO of short-lived radioactive isotopes substantiates the existence of this inadvertent criticality."
