Fukushima Cover Up




Fukushimais a thoroughly wreaked power plant and it will need a major effort to extractthe uranium fuel from the structures, just as happened at TMI and wasimpossible at Chernobyl.

What angers me here is the clearfailure of engineering design conception that was never caught from beginningto end.  You have a clear risk of a majorquake and a clear risk of a tsunami. That means that the cheapest protection is to place backup power outsideone of the risk envelopes.  A superearthquake resistant building is always impractical but a the tsunami risk issolved as easily as placing the hardware in a robust steel frame building thatis high enough to allow wash through by a massive flood wave. It is even cheap.

All disaster abatement programsbegin with securing power sources.

This mess looks like a designfrom the USA simply liftedand dropped on Japanto win the big building contract on the cheap. However it occurred, and everyone is long dead, the result was aterribly flawed design never tightened up , and yes someone signed of knowingperfectly well that he would not be off this world in the worst case.

As Hirose makes clear, thewreaked cores are dangerous and will not cool easily.  The first question today is whether the meltzones are even cooling at all. He points out that pumping water on them ispossibly even counter productive.

TMI took a special built robot toextract the core in the end.  I think weare looking at something as difficult here.


What They're Covering Up at Fukushima

"You Get 3,500,000 the NormalDose. You Call That Safe? And What Media Have Reported This? None!"


By HIROSE TAKASHI

Introduced by Douglas Lummis
Okinawa

Hirose Takashi has written a whole shelf full of books, mostly on thenuclear power industry and the military-industrial complex.  Probably hisbest known book is  Nuclear Power Plants for Tokyo in which he tookthe logic of the nuke promoters to its logical conclusion: if you are so surethat they're safe, why not build them in the center of the city, instead ofhundreds of miles away where you lose half the electricity in the wires? 

He did the TV interview that is partly translated below somewhatagainst his present impulses.  I talked to him on the telephone today(March 22 , 2011) and he told me that while it made sense to oppose nuclearpower back then, now that the disaster has begun he would just as soon remainsilent, but the lies they are telling on the radio and TV are so gross that hecannot remain silent.

I have translated only about the first third of the interview (you cansee the whole thing in Japanese on you-tube), the part that pertainsparticularly to what is happening at the Fukushimaplants.  In the latter part he talked about how dangerous radiation is ingeneral, and also about the continuing danger of earthquakes.

After reading his account, you will wonder, why do they keep onsprinkling water on the reactors, rather than accept the sarcophagussolution  [ie., entombing the reactors in concrete.

Editors.] I think there are a couple of answers.  One, thosereactors were expensive, and they just can't bear the idea of that huge afinancial loss.  But more importantly, accepting the sarcophagus solutionmeans admitting that they were wrong, and that they couldn't fix thethings.  On the one hand that's too much guilt for a human being to bear.

 On the other, it means thedefeat of the nuclear energy idea, an idea they hold to with almost religiousdevotion.  And it means not just the loss of those six (or ten) reactors,it means shutting down all the others as well, a financial catastrophe. If they can only get them cooled down and running again they can say, See,nuclear power isn't so dangerous after all.  Fukushima is a drama with the whole worldwatching, that can end in the defeat or (in their frail, I think groundless,hope) victory for the nuclear industry.

 Hirose's account can help us tounderstand what the drama is about. Douglas Lummis

Hirose Takashi:  The FukushimaNuclear Power Plant Accident and the State of the Media

Broadcast by Asahi NewStar, 17 March, 20:00

Interviewers: Yoh Sen'ei and Maeda Mari

Yoh:  Today many people saw water being sprayed on the reactorsfrom the air and from the ground, but is this effective?

Hirose:  . . . If you want to cool a reactor down with water, youhave to circulate the water inside and carry the heat away, otherwise it has nomeaning. So the only solution is to reconnect the electricity.  Otherwiseit’s like pouring water on lava.

Yoh:  Reconnect the electricity – that’s to restart the coolingsystem?

Hirose:  Yes.  The accident was caused by the fact that thetsunami flooded the emergency generators and carried away their fueltanks.  If that isn’t fixed, there’s no way to recover from this accident.

Yoh: Tepco [Tokyo Electric Power Company, owner/operator of thenuclear plants] says they expect to bring in a high voltage line this evening.

Hirose: Yes, there’s a little bit of hope there.  But what’sworrisome is that a nuclear reactor is not like what the schematic picturesshow (shows a graphic picture of a reactor, like those used on TV).  Thisis just a cartoon.  Here’s what it looks like underneath a reactorcontainer (shows a photograph).  This is the butt end of thereactor.  Take a look.  It’s a forest of switch levers and wires andpipes.  On television these pseudo-scholars come on and give us simpleexplanations, but they know nothing, those college professors.  Onlythe engineers know.  This is where water has been poured in.  Thismaze of pipes is enough to make you dizzy.  Its structure is too wildlycomplex for us to understand. For a week now they have been pouring waterthrough there.  And it’s salt water, right?  You pour salt water on ahot kiln and what do you think happens?

 You get salt. The salt will getinto all these valves and cause them to freeze.  They won’t move. This will be happening everywhere.  So I can’t believe that it’s just asimple matter of you reconnecting the electricity and the water will begin tocirculate.  I think any engineer with a little imagination can understandthis.  You take a system as unbelievably complex as this and then actuallydump water on it from a helicopter – maybe they have some idea of how thiscould work, but I can’t understand it.

Yoh:  It will take 1300 tons of water to fill the pools thatcontain the spent fuel rods in reactors 3 and 4.  This morning 30tons.  Then the Self Defense Forces are to hose in another 30 tons fromfive trucks.  That’s nowhere near enough, they have to keep it up. Is this squirting of water from hoses going to change the situation?

Hirose:  In principle, it can’t.  Because even when areactor is in good shape, it requires constant control to keep the temperaturedown to where it is barely safe.  Now it’s a complete mess inside, andwhen I think of the 50 remaining operators, it brings tears to my eyes.  Iassume they have been exposed to very large amounts of radiation, and thatthey have accepted that they face death by staying there.  And how longcan they last?  I mean, physically.  That’s what the situation hascome to now.  When I see these accounts on television, I want to tellthem, “If that’s what you say, then go there and do it yourself!”  Really,they talk this nonsense, trying to reassure everyone, trying to avoidpanic.  What we need now is a proper panic.  Because the situationhas come to the point where the danger is real. 

If I were Prime Minister Kan, I would order them to do what the SovietUnion did when the Chernobyl reactor blew up, the sarcophagus solution, burythe whole thing under cement, put every cement company in Japan to work, anddump cement over it from the sky.  Because you have to assume the worstcase.  Why?  Because in Fukushima there is the Daiichi Plant with sixreactors and the Daini Plant with four for a total of ten reactors.  Ifeven one of them develops the worst case, then the workers there must eitherevacuate the site or stay on and collapse.  So if, for example, one of thereactors at Daiichi goes down, the other five are only a matter of time. We can’t know in what order they will go, but certainly all of them willgo.  And if that happens, Daini isn’t so far away, so probably thereactors there will also go down.  Because I assume that workers will notbe able to stay there

I’m speaking of the worst case, but the probability is not low. This is the danger that the world is watching.  Only in Japan is itbeing hidden.  As you know, of the six reactors at Daiichi, four are in acrisis state.  So even if at one everything goes well and watercirculation is restored, the other three could still go down.  Four are incrisis, and for all four to be 100 per cent repaired, I hate to say it, but Iam pessimistic.  If so, then to save the people, we have to think aboutsome way to reduce the radiation leakage to the lowest level possible. Not by spraying water from hoses, like sprinkling water on a desert.  Wehave to think of all six going down, and the possibility of that happening isnot low. 

Everyone knows how long it takes a typhoon to pass over Japan; itgenerally takes about a week.  That is, with a wind speed of two meters persecond, it could take about five days for all of Japan to be covered withradiation.  We’re not talking about distances of 20 kilometers or 30kilometers or 100 kilometers.  It means of course Tokyo,Osaka. That’s how fast a radioactive cloud could spread. Of course it would depend onthe weather; we can’t know in advance how the radiation would bedistributed.  It would be nice if the wind would blow toward the sea, butit doesn’t always do that.  Two days ago, on the 15th, it was blowing towardTokyo. That’s how it is. . . .

Yoh: Every day the local government is measuring theradioactivity.  All the television stations are saying that whileradiation is rising, it is still not high enough to be a danger to health. Theycompare it to a stomach x-ray, or if it goes up, to a CT scan.  What isthe truth of the matter?

Hirose: For example, yesterday.  Around Fukushima Daiichi Station they measured 400millisieverts – that’s per hour.  With this measurement (Chief CabinetSecretary) Edano admitted for the first time that there was a danger to health,but he didn’t explain what this means.  All of the information media areat fault here I think.  They are saying stupid things like, why, we areexposed to radiation all the time in our daily life, we get radiation fromouter space.  But that’s one millisievert per year.  A year has 365days, a day has 24 hours; multiply 365 by 24, you get 8760.  Multiply the400 millisieverts by that, you get 3,500,000 the normal dose.  You callthat safe?  And what media have reported this?  None.  Theycompare it to a CT scan, which is over in an instant; that has nothing to dowith it.  The reason radioactivity can be measured is that radioactivematerial is escaping.  What is dangerous is when that material enters yourbody and irradiates it from inside.  These industry-mouthpiece scholarscome on TV and what to they say?  They say as you move away the radiationis reduced in inverse ratio to the square of the distance.  I want to saythe reverse.  Internal irradiation happens when radioactive material isingested into the body.  What happens?  Say there is a nuclearparticle one meter away from you. You breathe it in, it sticks inside yourbody; the distance between you and it is now at the micron level. One meter is1000 millimeters, one micron is one thousandth of a millimeter.  That’sa thousand times a thousand: a thousand squared.  That’s the real meaningof “inverse ratio of the square of the distance.”  Radiation exposure isincreased by a factor of a trillion.  Inhaling even the tiniest particle,that’s the danger.

Yoh:  So making comparisons with X-rays and CT scans has nomeaning.  Because you can breathe in radioactive material.

Hirose:  That’s right.  When it enters your body, there’s notelling where it will go.  The biggest danger is women, especiallypregnant women, and little children.  Now they’re talking about iodine andcesium, but that’s only part of it, they’re not using the proper detectioninstruments.  What they call monitoring means only measuring the amount ofradiation in the air.  Their instruments don’t eat.  What theymeasure has no connection with the amount of radioactive material. . . .

Yoh:  So damage from radioactive rays and damage from radioactivematerial are not the same.

Hirose:  If you ask, are any radioactive rays from the Fukushima Nuclear Stationhere in this studio, the answer will be no.  But radioactive particles arecarried here by the air.  When the core begins to melt down, elementsinside like iodine turn to gas.  It rises to the top, so if there is anycrevice it escapes outside.

Yoh:  Is there any way to detect this?

Hirose: I was told by a newspaper reporter that now Tepco is not inshape even to do regular monitoring.  They just take an occasionalmeasurement, and that becomes the basis of Edano’s statements.  You haveto take constant measurements, but they are not able to do that.  And youneed to investigate just what is escaping, and how much.  Thatrequires very sophisticated measuring instruments.  You can’t do it justby keeping a monitoring post.  It’s no good just to measure the level ofradiation in the air.  Whiz in by car, take a measurement, it’s high, it’slow – that’s not the point.  We need to know what kind of radioactivematerials are escaping, and where they are going – they don’t have a system inplace for doing that now.

Status report: Reactor-by-reactor at the Fukushima Daiichi plant


By the CNN Wire Staff
April 2, 2011 5:03 a.m. EDT


(CNN) -- Since March 11, the six reactors at the Fukushima Daiichi nuclear power plant havebeen in various states of disrepair after a 9.0-magnitude earthquake andsubsequent tsunami struck the area.
Here is the latest on each reactor and efforts to prevent furtherreleases of radioactive material.

Reactor No. 1
.
Hidehiko Nishiyama, an official with Japan's nuclear and industrialsafety agency, on Saturday knocked down a claim made a day earlier by U.S.Energy Secretary Steven Chu that 70% of the No. 1 reactor's core has sufferedsevere damage. Noting that sensors have been unreliable, Chusaid the calcuation was based on the fact that radiation levels have been toohigh for workers to get inside. But Nishiyama said that Japanese authorities'data indicates only 3% damage to the unit.
.
Workers are preparing to inject nitrogen into the No. 1 reactor (aswell as at least two others) in an order to prevent another explosion caused bya buildup of hydrogen, Nishiyama said Saturday. A hydrogen explosion -- anindicator of possible core damage -- blew the roof and upper walls off thebuilding housing the reactor on March 12.

Just after midnight Friday, a TokyoElectric official said that iodine-131 levels in ground water from a pipe nearthe No. 1 reactor had 10,000 times the standard limit. But the utility laterbacktracked, promising to get more clarity later. Japanese Chief CabinetSecretary Yukio Edano addressed this confusion in a press conference laterFriday, noting that a "constant amount of radiation" appeared to begetting into the groundwater and noting that further tests are forthcoming.
.
Water levels in an exposed maintenance tunnel leading from the No. 1unit's turbine building had dropped 1 meter from its previous measure, a Tokyo Electric officialsaid Friday. The authorities assume this relates efforts to pump water out ofthe building's basement, which had been flooded with radioactive water.
.
Tsunehisa Katsumata, chairman of Tokyo Electric Power Company that runsthe nuclear power plant, said Wednesday, "Looking at currentconditions, ... there are no options other than decommissioning" the No. 1reactor, as well as Nos. 2, 3 and 4 units. This would mean that the reactorwould never be used to produce electricity again.
.
This reactor's core has been damaged, but its containment vessel wasnot, according to the JapanAtomic Industrial Forum, an industry trade group that tracks information fromgovernment and TokyoElectric officials. The containment vessel is a concrete and steel structurethat keeps radioactive material inside the reactor.
.
Lighting has been restored to the No. 1 and No. 2 units' control room,though the overall power supply in both is subpar.
.
Reactor No. 2
.
Water from a two-meter deep, concrete-lined basin outside the No. 2reactor complex could be seen escaping into the sea through a roughly 20-cm(8-inch) crack, an official the Tokyo Electric Power Company told reportersSaturday afternoon. But the company could not explain how the water was gettinginto the sump.

Radiation levels in the pit have been measured over 1,000 millisievertsper hour, which is more than 330 times the dose an average resident of anindustrialized country naturally receives in a year. Utility company officialssaid Saturday that the plan was to to fill the sump with concrete in order tostop the leakage.
.
A planned two-day project began Saturday to install a camera inear n anexposed maintenance tunnel connected to the No. 2 unit's turbine building inorder to help pinpoint potential leaks, a Tokyo Electric official said.
.
A day earlier, a utility company official said that water levels inthat tunnel had fallen one meter. This followed earlier official reports thatthis water had radiation levels of 1,000 millisieverts per hour -- which ismore than 330 times the dose that an average individual living in a developedcountry receives per year and can result in vomiting and up to a 30 percenthigher risk of cancer, according to the International Atomic Energy Agency.
.
There was no immediate response Saturday to a claim, made by U.S.Energy Secretary Steven Chu, that the No. 2 reactor core had suffered a 33percent meltdown. But Nishiyama, of Japan'snuclear safey agency, did try to debunk Chu'sclaims about the No. 1 reactor.
.
As with the Nos. 1 and 3 units, there is a plan to inject nitrogen intothe No. 2 reactor in order to prevent a buildup of hydrogen that might cause anexplosion. One such blast occurred at the No. 2 unit on March 15.

Katsumata said Wednesday that, "looking at currentconditions," the No. 2 reactor and three others would be decommissioned --meaning it would never be used to produce electricity again.
.
Japanese Chief Cabinet Secretary Yukio Edano has said that he hasreceived a report that the No. 2 unit's containment vessel "is damaged andwater is leaking."
.
Workers have been pumping freshwater into the No. 2 unit's reactorcore, which the JapanAtomic Industrial Forum says has been damaged. The building housing the reactorhas only been "slightly damaged," according to the industry group.
.
Lighting has been restored to the No. 1 and No. 2 units' control room,though the overall power supply in both is subpar.
.
Reactor No. 3
.
Japan's nuclear safety agency announced plans topump in nitrogen -- a non-flammable sustance -- into the No. 2 reactor and twoothers in a bid to prevent an explosion caused by the buildup of hydrogen.Eleven people were injured on March 14 when one such explosion occurred at theNo. 2 unit.
.
The water levels in the exposed maintenance tunnel leading from the No.3 unit's turbine building has decreased by 1.5 meters, a Tokyo Electricofficial said Friday. Earlier, tests revealed that water in this tunnel hadhigh levels of radioactivity -- prompting authorities to make it a priority todrain the tunnels, to prevent this water from overflowing and seeping into theground. But by Friday, the utility company said the drainage had been largelyeffective.
.
Like the Nos. 1, 2 and 4 reactors, the No. 3 reactor is likely to putout of service permanently even after the crisis resolves, Katsumata saidWednesday. Among other issues, the use of seawater in the post-crisis responsehas corroded the reactor, experts have said.
.
The No. 3 reactor had been of particular concern because it is the onlyone to use mixed-oxide fuel that contains a small percentage of plutonium,which is also a byproduct in other reactors. A small amount of plutonium wasdetected in soil samples on the plant grounds last week, Tokyo Electric reported Monday. Edano saidTuesday that it was "likely" the plutonium came from this reactor.
.
The cooling pool where spent fuel is stored may also have been damaged,the JapanAtomic Industrial Forum reports. Workers used a concrete pump to douse thespent fuel pool with water Tuesday, said Hidehiko Nishiyama of Japan's nuclearand industrial safety agency.
.
Freshwater is being injected into the No. 3 reactor core in order toprevent overheating of nuclear fuel inside.
.
The No. 3 reactor is believed to have suffered core damage, anda hydrogen explosion did extensive damage to the building surrounding thereactor March 14.
.
Reactor No. 4
.
Freshwater was injected into the No, 4 unit's spent nuclear fuel poolon Friday using a concrete pump truck, a TokyoElectric official said.
.
Workers restored power in the reactor's control room Tuesday -- a movethat officials say could be a key step in efforts to bring cooling systems backonline.
.
This reactor was offline in a scheduled outage when the earthquake hit.Still, it has had several major problems since then, including a March 15 firethat damaged the building that houses the reactor.
.
The nuclear fuel rods were in the unit's spent fuel pool, but not inthe reactor itself. The reactor's pool of spent nuclear fuel was "possiblydamaged," which is why authorities have made repeated efforts to pourwater onto the structure.
.
Reactors Nos. 5 and 6
.
Reactors No. 5 and 6 were not in operation at the time of the earthquakeand are in "cold shutdown," Japan's nuclear and industrialsafety agency reports.
.
The reactors were shut down for a scheduled outage when the quake hitand there are no major issues with the reactors and cores themselves. Thecooling systems in the pools of spent nuclear fuel are thought to befunctioning, though there are continued concerns about keeping power running tothe systems.
.
Three holes were punched in each building earlier to relieve pressureand prevent a feared hydrogen explosion.
