Roger’s note: I posted a few days ago a similar article by the same author. Frankly, what is happening at Fukushima scares the hell out of me, and it seems that nobody is listening. This should cause you to lose sleep: “As former Ambassador Mitsuhei Murata has put it: full-scale releases from Fukushima “would destroy the world environment and our civilization. This is not rocket science, nor does it connect to the pugilistic debate over nuclear power plants. This is an issue of human survival.”
More than 48,000 global citizens have now signed a petition at www.nukefree.org asking the United Nations and the world community to take charge of the stricken Fukushima nuclear plant. Another 35,000 have signed at www.rootsaction.org. An independent advisory group of scientists and engineers is also in formation. The signatures are pouring in from all over the world. By November, they will be delivered to the United Nations.
The corporate media has blacked out meaningful coverage of the most critical threat to global health and safety in decades.
The much-hyped “nuclear renaissance” has turned into a global rout. In the face of massive grassroots opposition and the falling price of renewable energy and natural gas, operating reactors are shutting and proposed new ones are being cancelled.
This lessens the radioactive burden on the planet. But it makes the aging reactor fleet ever more dangerous. A crumbling industry with diminished resources and a disappearing workforce cannot safely caretake the decrepit, deteriorating 400-odd commercial reactors still licensed to operate worldwide.
All of which pales before the crisis at Fukushima. Since the 3/11/2011 earthquake and tsunami, the six-reactor Daichi site has plunged into lethal chaos.
For decades the atomic industry claimed vehemently that a commercial reactor could not explode. When Chernobyl blew, it blamed “inferior” Soviet technology.
But Fukushima’s designs are from General Electric (some two dozen similar reactors are licensed in the US). At least four explosions have rocked the site. One might have involved nuclear fission. Three cores have melted into the ground. Massive quantities of water have been poured where the owner, Tokyo Electric (Tepco), and the Japanese government think they might be, but nobody knows for sure.
As the Free Press has reported, steam emissions indicate one or more may still be hot. Contaminated water is leaking from hastily-constructed tanks. Room for more is running out. The inevitable next earthquake could rupture them all and send untold quantities of poisons pouring into the ocean.
The worst immediate threat at Fukushima lies in the spent fuel pool at Unit Four. That reactor had been shut for routine maintenance when the earthquake and tsunami hit. The 400-ton core, with more than 1300 fuel rods, sat in its pool 100 feet in the air.
Spent fuel rods are the most lethal items our species has ever created. A human standing within a few feet of one would die in a matter of minutes. With more than 11,000 scattered around the Daichi site, radiation levels could rise high enough to force the evacuation of all workers and immobilize much vital electronic equipment.
Spent fuel rods must be kept cool at all times. If exposed to air, their zirconium alloy cladding will ignite, the rods will burn and huge quantities of radiation will be emitted. Should the rods touch each other, or should they crumble into a big enough pile, an explosion is possible. By some estimates there’s enough radioactivity embodied in the rods to create a fallout cloud 15,000 times greater than the one from the Hiroshima bombing.
The rods perched in the Unit 4 pool are in an extremely dangerous position. The building is tipping and sinking into the sodden ground. The fuel pool itself may have deteriorated. The rods are embrittled and prone to crumbling. Just 50 meters from the base is a common spent fuel pool containing some 6,000 fuel rods that could be seriously compromised should it lose coolant. Overall there are some 11,000 spent rods scattered around the Fukushima Daichi site.
Dangerous as the process might be, the rods in the Unit Four fuel pool must come down in an orderly fashion. Another earthquake could easily cause the building to crumble and collapse. Should those rods crash to the ground and be left uncooled, the consequences would be catastrophic.
Tepco has said it will begin trying to remove the rods from that pool in November. The petitions circulating through www.nukefree.org and www.moveon.org , as well as at rootsaction.org and avaaz.org, ask that the United Nations take over. They ask the world scientific and engineering communities to step in. The Rootsaction petition also asks that $8.3 billion slated in loan guarantees for a new US nuke be shifted instead to dealing with the Fukushima site.
It’s a call with mixed blessings. The UN’s International Atomic Energy Agency is notoriously pro-nuclear, charged with promoting atomic power as well as regulating it. Critics have found the IAEA to be secretive and unresponsive.
But Tepco is a private utility with limited resources. The Japanese government has an obvious stake in downplaying Fukushima’s dangers. These were the two entities that approved and built these reactors.
While the IAEA is imperfect, its resources are more substantial and its stake at Fukushima somewhat less direct. An ad hoc global network of scientists and engineers would be intellectually ideal, but would lack the resources for direct intervention.
Ultimately the petitions call for a combination of the two.
It’s also hoped the petitions will arouse the global media. The moving of the fuel rods from Unit Four must be televised. We need to see what’s happening as it happens. Only this kind of coverage can allow global experts to analyze and advise as needed.
Let’s all hope that this operation proves successful, that the site be neutralized and the massive leaks of radioactive water and gasses be somehow stopped.
As former Ambassador Mitsuhei Murata has put it: full-scale releases from Fukushima “would destroy the world environment and our civilization. This is not rocket science, nor does it connect to the pugilistic debate over nuclear power plants. This is an issue of human survival.”

ROGER’S NOTE: I AM NO SCIENTIST, BUT IF THE ANALYSIS CONTAINED IN THIS ARTICLE IS CREDIBLE, THEN IT SHOULD BE FRONT PAGE NEWS ON EVERY NEWSPAPER IN THE WORLD. FRIGHTENING, TRULY FRIGHTENING.
OpEdNews Op Eds 9/21/2013 at 15:08:52
We are now within two months of what may be humankind’s most dangerous moment since the Cuban Missile Crisis.
There is no excuse for not acting. All the resources our species can muster must be focussed on the fuel pool at Fukushima Unit 4.
Fukushima’s owner, Tokyo Electric (Tepco), says that within as few as 60 days it may begin trying to remove more than 1,300 spent fuel rods from a badly damaged pool perched 100 feet in the air. The pool rests on a badly damaged building that is tilting, sinking and could easily come down in the next earthquake, if not on its own.
Some 400 tons of fuel in that pool could spew out more than 15,000 times as much radiation as was released at Hiroshima.
The one thing certain about this crisis is that Tepco does not have the scientific, engineering or financial resources to handle it. Nor does the Japanese government. The situation demands a coordinated worldwide effort of the best scientists and engineers our species can muster.
Why is this so serious?
We already know that thousands of tons of heavily contaminated water are pouring through the Fukushima site, carrying a devil’s brew of long-lived poisonous isotopes into the Pacific. Tuna irradiated with fallout traceable to Fukushima have already been caught off the coast of California. We can expect far worse.
Tepco continues to pour more water onto the proximate site of three melted reactor cores it must somehow keep cool. Steam plumes indicate fission may still be going on somewhere underground. But nobody knows exactly where those cores actually are.
Much of that irradiated water now sits in roughly a thousand huge but fragile tanks that have been quickly assembled and strewn around the site. Many are already leaking. All could shatter in the next earthquake, releasing thousands of tons of permanent poisons into the Pacific.
The water flowing through the site is also undermining the remnant structures at Fukushima, including the one supporting the fuel pool at Unit Four.
More than 6,000 fuel assemblies now sit in a common pool just 50 meters from Unit Four. Some contain plutonium. The pool has no containment over it. It’s vulnerable to loss of coolant, the collapse of a nearby building, another earthquake, another tsunami and more.
Overall, more than 11,000 fuel assemblies are scattered around the Fukushima site. According to long-time expert and former Department of Energy official Robert Alvarez, there is more than 85 times as much lethal cesium on site as was released at Chernobyl.
Radioactive hot spots continue to be found around Japan. There are indications of heightened rates of thyroid damage among local children.
The immediate bottom line is that those fuel rods must somehow come safely out of the Unit Four fuel pool as soon as possible.
Just prior to the 3/11/11 earthquake and tsunami that shattered the Fukushima site, the core of Unit Four was removed for routine maintenance and refueling. Like some two dozen reactors in the US and too many more around the world, the General Electric-designed pool into which that core now sits is 100 feet in the air.
Spent fuel must somehow be kept under water. It’s clad in zirconium alloy which will spontaneously ignite when exposed to air. Long used in flash bulbs for cameras, zirconium burns with an extremely bright hot flame.
Each uncovered rod emits enough radiation to kill someone standing nearby in a matter of minutes. A conflagration could force all personnel to flee the site and render electronic machinery unworkable.
According to Arnie Gundersen, a nuclear engineer with forty years in an industry for which he once manufactured fuel rods, the ones in the Unit 4 core are bent, damaged and embrittled to the point of crumbling. Cameras have shown troubling quantities of debris in the fuel pool, which itself is damaged.
The engineering and scientific barriers to emptying the Unit Four fuel pool are unique and daunting, says Gundersen. But it must be done to 100% perfection.
Should the attempt fail, the rods could be exposed to air and catch fire, releasing horrific quantities of radiation into the atmosphere. The pool could come crashing to the ground, dumping the rods together into a pile that could fission and possibly explode. The resulting radioactive cloud would threaten the health and safety of all of us.
Chernobyl’s first 1986 fallout reached California within 10 days. Fukushima’s in 2011 arrived in less than a week. A new fuel fire at Unit 4 would pour out a continuous stream of lethal radioactive poisons for centuries.
Former Ambassador Mitsuhei Murata says full-scale releases from Fukushima “would destroy the world environment and our civilization. This is not rocket science, nor does it connect to the pugilistic debate over nuclear power plants. This is an issue of human survival.”
Neither Tokyo Electric nor the government of Japan can go this alone. There is no excuse for deploying anything less than a coordinated team of the planet’s best scientists and engineers.
For now, we are petitioning the United Nations and President Obama to mobilize the global scientific and engineering community to take charge at Fukushima and the job of moving these fuel rods to safety.
You can sign the petition at: http://www.nukefree.org/crisis-fukushima-4-petition-un-us-global-response
If you have a better idea, please follow it. But do something and do it now.
The clock is ticking. The hand of global nuclear disaster is painfully close to midnight.

Japan’s Nuclear Regulatory Authority taskforce says TEPCO’s “sense of crisis is weak”
“Right now, we have an emergency.”
This was the warning given on Monday by Japan’s nuclear regulatory body, the Nuclear Regulatory Authority (NRA), describing the radioactive water seeping into the ocean from the crisis-stricken Fukushima nuclear plant.
The emergency shows “why you can’t just leave it up to [plant operator] TEPCO alone,” Shinji Kinjo, head of an NRA task force, told Reuters.
Kinjo slammed TEPCO, which created a “temporary solution” of an underground barrier to stop water contamination, for having a “sense of crisis [that] is weak.” That underground barrier has been breached, allowing the radioactive water to be released, and could accelerate the flow of radioactive discharge from the plant into the ocean.
In July, TEPCO admitted for the first time that contaminated groundwater was leaking from the Fukushima plant into the ocean, and on Sunday gave its first estimate to the public on the amount of radioactive tritium that has leaked into the ocean since the disaster began in March of 2011.
NRA chief Shunichi Tanaka told reporters earlier last month, however, that his agency ‘strongly suspected’ that Fukushima was leaking radioactivity into the ocean and has been for two years.
Last month, former head of the US Nuclear Regulatory Commission Dale Klein was among other foreign nuclear experts at a panel in Tokyo blasting TEPCO’s handling of the crisis including cover-ups of the extent of the damage. “These actions indicate that you (TEPCO) don’t know what you are doing,” he said. “You do not have a plan and that you are not doing all you can to protect the environment and the people.”

Texas nuclear plants planned by Tokyo Electric. (Image: NINA)
I need to speak to you, not as a reporter, but in my former capacity as lead investigator in several government nuclear plant fraud and racketeering investigations.
I don’t know the law in Japan, so I can’t tell you if Tokyo Electric Power Co (TEPCO) can plead insanity to the homicides about to happen.
But what will Obama plead? The administration, just months ago, asked Congress to provide a $4 billion loan guarantee for two new nuclear reactors to be built and operated on the Gulf Coast of Texas – by TEPCO and local partners. As if the Gulf hasn’t suffered enough. Here are the facts about TEPCO and the industry you haven’t heard on CNN:
The failure of emergency systems at Japan’s nuclear plants comes as no surprise to those of us who have worked in the field.
Nuclear plants the world over must be certified for what is called “SQ” or “Seismic Qualification.” That is, the owners swear that all components are designed for the maximum conceivable shaking event, be it from an earthquake or an exploding Christmas card from al-Qaeda.
The most inexpensive way to meet your SQ is to lie. The industry does it all the time. The government team I worked with caught them once, in 1988, at the Shoreham plant in New York. Correcting the SQ problem at Shoreham would have cost a cool billion, so engineers were told to change the tests from “failed” to “passed.”
The company that put in the false safety report? Stone & Webster, now the nuclear unit of Shaw Construction, which will work with TEPCO to build the Texas plant. Lord help us.
Last night, I heard CNN reporters repeat the official line that the tsunami disabled the pumps needed to cool the reactors, implying that water unexpectedly got into the diesel generators that run the pumps.
These safety backup systems are the “EDGs” in nuke-speak: Emergency Diesel Generators. That they didn’t work in an emergency is like a fire department telling us they couldn’t save a building because “it was on fire.”
What dim bulbs designed this system? One of the reactors dancing with death at Fukushima Station 1 was built by Toshiba. Toshiba was also an architect of the emergency diesel system.
Now be afraid. Obama’s $4 billion bailout in the making is called the South Texas Project. It’s been sold as a red-white-and-blue way to make power domestically with a reactor from Westinghouse, a great American brand. However, the reactor will be made substantially in Japan by the company that bought the US brand name, Westinghouse – Toshiba.
I once had a Toshiba computer. I only had to send it in once for warranty work. However, it’s kind of hard to mail back a reactor with the warranty slip inside the box if the fuel rods are melted and sinking halfway to the earth’s core.
TEPCO and Toshiba don’t know what my son learned in eighth grade science class: tsunamis follow Pacific Rim earthquakes. So, these companies are real stupid, eh? Maybe. More likely is that the diesels and related systems wouldn’t have worked on a fine, dry afternoon.
Back in the day, when we checked the emergency backup diesels in America, a mind-blowing number flunked. At the New York nuclear plant, for example, the builders swore under oath that their three diesel engines were ready for an emergency. They’d been tested. The tests were faked; the diesels run for just a short time at low speed. When the diesels were put through a real test under emergency-like conditions, the crankshaft on the first one snapped in about an hour, then the second and third. We nicknamed the diesels, “Snap, Crackle and Pop.”
(Note: Moments after I wrote that sentence, word came that two of three diesels failed at the Tokai Station as well.)
In the US, we supposedly fixed our diesels after much complaining by the industry. But in Japan, no one tells TEPCO to do anything the Emperor of Electricity doesn’t want to do.
I get lots of confidential notes from nuclear industry insiders. One engineer, a big name in the field, is especially concerned that Obama waved the come-hither check to Toshiba and TEPCO to lure them to America. The US has a long history of whistleblowers willing to put themselves on the line to save the public. In our racketeering case in New York, the government only found out about the seismic test fraud because two courageous engineers, Gordon Dick and John Daly, gave our team the documentary evidence.
In Japan, it’s simply not done. The culture does not allow the salary men, who work all their lives for one company, to drop the dime.
Not that US law is a wondrous shield: both engineers in the New York case were fired and blacklisted by the industry. Nevertheless, the government (local, state, federal) brought civil racketeering charges against the builders. The jury didn’t buy the corporation’s excuses and, in the end, the plant was, thankfully, dismantled.
Am I on some kind of xenophobic anti-Nippon crusade? No. In fact, I’m far more frightened by the American operators in the South Texas nuclear project, especially Shaw. Stone & Webster, now the Shaw nuclear division, was also the firm that conspired to fake the EDG tests in New York . (The company’s other exploits have been exposed by their former consultant, John Perkins, in his book, “Confessions of an Economic Hit Man.”) If the planet wants to shiver, consider this: Toshiba and Shaw have recently signed a deal to become worldwide partners in the construction of nuclear stations.
The other characters involved at the South Texas Plant that Obama is backing should also give you the willies. But as I’m in the middle of investigating the American partners, I’ll save that for another day.
So, if we turned to America’s own nuclear contractors, would we be safe? Well, two of the melting Japanese reactors, including the one whose building blew sky high, were built by General Electric of the Good Old US of A.
After Texas, you’re next. The Obama administration is planning a total of $56 billion in loans for nuclear reactors all over America.
And now, the homicides:
CNN is only interested in body counts, how many workers burnt by radiation, swept away or lost in the explosion. These plants are now releasing radioactive steam into the atmosphere. Be skeptical about the statements that the “levels are not dangerous.” These are the same people who said these meltdowns could never happen. Over years, not days, there may be a thousand people, two thousand, ten thousand who will suffer from cancers induced by this radiation.
In my New York investigation, I had the unhappy job of totaling up post-meltdown “morbidity” rates for the county government. It would be irresponsible for me to estimate the number of cancer deaths that will occur from these releases without further information; but it is just plain criminal for the TEPCO shoguns to say that these releases are not dangerous.
Indeed, the fact that residents near the Japanese nuclear plants were not issued iodine pills to keep at the ready shows TEPCO doesn’t care who lives and who dies, whether in Japan or the USA. The carcinogenic isotopes that are released at Fukushima are already floating to Seattle with effects we simply cannot measure.
Heaven help us. Because Obama won’t.
