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.

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.

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.
Nuclear’s Demise, From Fukushima to Vermont August 31, 2013Posted by rogerhollander in Energy, Environment, Japan, Nuclear weapons/power, Vermont.

Fukushima showed us the intolerable costs of nuclear power. The citizens of Vermont show us the benefits of shutting it down
Welcome to the nuclear renaissance.
Entergy Corp, one of the largest nuclear-power producers in the US, issued a surprise press release Tuesday, saying it plans “to close and decommission its Vermont Yankee Nuclear Power Station in Vernon, Vermont. The station is expected to cease power production after its current fuel cycle and move to safe shutdown in the fourth quarter of 2014.” Although the press release came from the corporation, it was years of people’s protests and state legislative action that forced its closure. At the same time that activists celebrate this key defeat of nuclear power, officials in Japan admitted that radioactive leaks from the Fukushima Daiichi nuclear catastrophe are far worse than previously acknowledged.
“It took three years, but it was citizen pressure that got the state Senate to such a position”, nuclear-energy consultant Arnie Gundersen told me of Entergy’s announcement. He has coordinated projects at 70 nuclear plants around the country and now provides independent testimony on nuclear and radiation issues. He explained how the state of Vermont, in the first such action in the country, had banned the plant from operating beyond its original 40-year permit. Entergy was seeking a 20-year extension.
The legislature, in that 26-to-4 vote, said: ‘No, we’re not going to allow you to reapply. It’s over. You know, a deal’s a deal. We had a 40-year deal.’ Well, Entergy went to first the federal court here in Vermont and won, and then went to an appeals court in New York City and won again on the issue, as they framed it, that states have no authority to regulate safety.
Despite prevailing in the courts, Entergy bowed to public pressure.
Back in 2011, Vermont Governor Peter Shumlin, who called Entergy “a company that we found we can’t trust”, said on “Democracy Now!“:
We’re the only state in the country that’s taken power into our own hands and said that, without an affirmative vote from the state legislature, the public service board cannot issue a certificate of public good to legally operate a plant for another 20 years. Now, the Senate has spoken … saying no, it’s not in Vermont’s best interest to run an aging, leaking nuclear-power plant. And we expect that our decision will be respected.
The nuclear-power industry is at a critical crossroads. The much-touted nuclear renaissance is collapsing, most notably in the aftermath of the Fukushima disaster, compounded by the global financial crisis. In a recent paper titled “Renaissance in Reverse”, Mark Cooper, senior fellow for economic analysis at the Vermont Law School, writes, “The problem for old nuclear reactors has become acute.” The costs to operate, and to repair, these plants have prompted operators to shutter five of the 104 operating power generating reactors in the US this year alone, leaving 99. Cooper has identified 30 more that he estimates will be shut down, because “the economics of old reactors are very dicey”.
The profound consequences of the Fukushima Daiichi nuclear-power accident are still unfolding, as this week the Japanese Nuclear Regulatory Agency increased its assessment of the situation there to “level three”, or serious, on the International Nuclear and Radiological Event Scale. The original accident in March 2011 was rated a “seven” on that scale, the highest, most severe, threat. The nuclear fuel rods there require constant cooling by water. The spent cooling water is highly radioactive. The Tokyo Electric Power Co, which ran Fukushima and which has been responsible for all the cleanup, has been storing the radioactive water in hastily-constructed water tanks, which are now leaking. Gundersen said:
The surveys of the area determined that the radiation coming from the ground was five times more in an hour than a normal person would get in a year. Radioactive water is leaking out of this plant as fast as it’s leaking in. So, you’ve got something on the order of 400 tons to maybe even as much as a thousand tons of water a day leaking off of the mountains around Fukushima into the basement of this plant. Well, the basement is highly radioactive because the containment has failed and radioactive material is leaking out from the nuclear core into the other buildings. That’s being exposed to this clean groundwater and making it extraordinarily radioactive. … And the problem is going to get worse.
The Fukushima disaster has been compared to the catastrophe in Chernobyl, where a nuclear plant exploded in 1986, making the surrounding region uninhabitable. The radiation is spilling out of Fukushima into an ever-growing radioactive plume in the Pacific Ocean.
Fukushima shows us the intolerable costs of nuclear power. The citizens of Vermont show us the benefits of just saying no.

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.
