[Column] “No fuel” vs “Is fuel” in reactor4 pool

Note : If you are from the international mass media, Don’t read this site before taking a contact with me.

 

 

The discussion about reactor4 pool is all around on the internet.

Some people say there are no fuels in reactor4 pool anymore, some say there are.

 

I personally don’t know which one is true.

 

First of all, I would like to clarify that there was no fuel in reactor4 itself. Reactor4 and reactor4 pool are different. I’m a little afraid this may be where this entire argument started.

 

Anyway, “No fuel” side says there mustn’t be the fuel because it steamed a lot in 311.

Actually the NRC document says there was no water in the pool.

However actually the pool can’t indicate the water level when it goes lower than a certain level according to a NRC document that anonymous leaked in the summer of 2012. Nobody therefore can prove there was no water in the pool. It’s only the visual inspection.

 

American nuclear plants also use the same structure of the spent fuel pool as reactor4. For this reason, NRC might be pressuring Tepco and Japanese government to conceal the things about reactor4 pool possibly.

 

From the report of the governmental accident investigation committee, which my old teacher is also a member of, at least 2 fires were observed in the different places of reactor4 building. It is not clear who and how put it out.

Sure just “fire” cannot ruin the nuclear plant building that much.

The explosion of reactor4 is reported to be the “hydrogen explosion” by Tepco, but the committee finds it still questionable.

However, 5 different seismic monitors recorded an explosive shock 2 mins before the “explosion” itself. (cf, [Reactor4] Explosive shock was detected before the explosion [URL])

 

Everything is messed up.

 

The basis to think there are still fuel is the fact that Tepco removed 2 assemblies of the new fuel last year. It’s a little questionable if they can manipulate thousands of the workers for over one year.

 

As a matter of fact, it may be worse if there are still fuel.

Tepco has made no prevention in case the fuel reaches critical state. This is what scares me the most. They only say it can’t go critical state because they pick up one assembly each time. They state even if it goes, it won’t affect the outside of the plant area.

 

Because it is not supposed to have an accident, they don’t take any prevention. This is the tradition of nuclear industry and this is how 311 happened.

 

 

I reject the international mass media to read this site without taking a contact with me.I know some of the mass media corporations read Fukushima Diary to understand the trend so they know when to report about Fukushima as if they were independently following it for a long time.
In short, they make you individual readers pay for this site while they pay nothing, and when they publish the “authorized news”, you pay for the “secondhand news”, which is nothing new for us.
This site is free for the individual readers, but not for corporations.In the world, this site is nearly the only source about Fukushima. I came here alone without any supporting organizations, background or anything. I’m not pleased to be exploited by the corporations that didn’t even properly report about Fukushima when 311 took place.

I demand them to take a contact with me BEFORE reading this site whatever the purpose is.

[Édito] Piscine du réacteur 4 : “pas de combustible” vs “avec combustible”
Note : Si vous êtes de la grande presse internationale, ne lisez pas ce site sans avoir préalablement pris contact avec moi.

 

Un débat sur la piscine du réacteur 4 court partout sur internet.
Certains disent qu’il n’y a plus de combustible dans la piscine du réacteur 4, d’autres disent qu’il en reste.

Personnellement, je ne sais pas qui a raison.

D’abord, je voudrais clarifier le fait qu’il n’y avait pas de combustible dans le réacteur lui-même. Le réacteur 4 et la piscine du réacteur 4 sont deux choses différentes. Je crains que ceci soit à l’origine de toutes ces discussions.

De toute façon, les “pas de combustible” disent qu’il ne peut pas y en avoir parce que ça a fait beaucoup de vapeur en mars 2011.
De fait, le document de la NRC (=Commission de Régulation du Nucléaire) dit qu’il n’y avait plus d’eau dans la piscine.
Néanmoins, selon un autre document de la NRC, que les anonymous avaient fait fuir à l’été 2012, la piscine n’indique plus le niveau de son eau quand il passe en-dessous d’un certain niveau, en fait. Donc personne ne peut prouver s’il y avait ou non de l’eau dans la piscine. On ne peut le savoir que par inspection visuelle.

Les centrales nucléaires américaines ont les mêmes piscines à combustibles usagés que le réacteur 4. C’est pourquoi il est possible que la NRC ait fait pression sur Tepco et le gouvernement japonais pour annuler tout ce qui concerne la piscine du réacteur 4.

Selon le rapport de la commission d’enquête du gouvernement sur l’accident, dont mon ancien professeur a fait partie, au moins 2 incendies ont été observés en différents endroits du bâtiment du réacteur 4. Il n’est pas clairement établi qui l’a publié et comment.
Il est certain qu’un simple “incendie” ne peut pas transformer à ce point-là le bâtiment de la centrale nucléaire en tas de ruines.
L’explosion du réacteur 4 avait été décrite par Tepco comme étant une “explosion d’hydrogène” mais les découvertes de la commission d’enquête montrent qu’on peut en douter.
De plus, 5 sismographes différents ont enregistré le choc d’une explosion 2 mns avant “l’explosion” elle-même. (cf. [Réacteur4] Le choc de l’explosion a été enregistré avant l’explosion)

Tout est mélangé.

La base pour penser qu’il reste des combustibles dans la piscine est le fait que Tepco en a retiré 2 assemblages neufs l’an dernier. On peut s’interroger sur leur capacité à pouvoir utiliser des centaines de travailleurs pendant plus d’une année.

De fait, s’il reste des combustibles c’est pire.
Tepco n’a pris aucune mesure de précaution au cas où le combustible atteindrait l’état critique. C’est ce qui m’effraye le plus. Ils ont seulement dit que ça ne peut pas atteindre l’état critique parce qu’ils ne prennent qu’un seul assemblage à la fois. Ils affirment que même si ça arrivait, ça ne s’étendrait pas au-delà du périmètre de la centrale.

Ils n’ont pris aucune mesure de prévention parce qu’ils supposent qu’il n’y aura pas d’accident. C’est une tradition dans l’industrie nucléaire et c’est comme ça que le 11-3 est arrivé.

J’interdis à la grande presse internationale de lire et d’utiliser ce site sans préalablement prendre contact avec moi. Je sais que certaines grandes sociétés de presse lisent le Fukushima Diary pour comprendre la tendance et trouver quand rendre compte de la situation de Fukushima comme s’ils la suivaient indépendamment depuis longtemps. En résumé, ils vous font payer à vous, simples lecteurs, ce qu’ils prennent gratuitement dans ce site et lorsqu’ils publient des “nouvelles de première main” vous payez pour des “nouvelles resucées”, qui n’ont rien de nouveau pour nous. Ce site est gratuit pour les lecteurs individuels, pas pour les sociétés. Ce site est pratiquement la seule source au monde sur Fukushima. Je viens ici seul sans aucun soutien d’organisation quelconque, ni références, ni rien. Je n’apprécie pas de me faire exploiter par ces sociétés qui n’ont même pas été foutues de relater correctement ce qui se passait à Fukushima quand a eu lieu le mois de mars 2011.

Je leur demande de prendre contact avec moi AVANT de lire ce site dans quelque but que ce soit.

  1. The Fuel bundles in the Reactor 4 SFP were allegedly checked about a year ago. They were found to mostly appear intact. Since they could only take pictures from above, this is not very indicative of the state of the fuel below, however it appears as if the SFP could be cleared without complications. Cross your fingers. The remains of Reactors 1-3 are far more difficult to address. Nobody knows what the inside of the reactors looks like at the moment. Allegedly, they found parts of a molten core in a “Torus”. That would be a very bad sign. They would have to dig radioactive soil to even reach the Torus room. Every part of the molten core is dangerously radiocative, so much that you can not work close to it or even send a robot. You have to do everything with long, solid tools.

  2. Bastion zapf do you have any sources for all your condescending statements?
    Please cite your references or c.v for the publics benefit

  3. If workers can go into building #4…that would indicate less damage to rods…my understanding is the controversy is over the loading of the damaged fuel rods, into casks that are to be paced in the empty reactor chamber, then transported to a other location.

    1. Remember the wobbly video taken from a drone, put out in April or so 2011? Remember the molten lava hanging out the side of #4?

      Remember the video showing the removal of two fuel assemblies from #4?
      Remember the worker putting his gloved hand on one of the assemblies to correct its position?
      Some say that a foot away from such an assembly would give the worker a 10,000 S/h blast and that he’d be dead in an hour, or something to that effect.

      Whatever, it’s a distraction, not the main event, surely.

  4. Normal Reactor Fueling Operation

    The usual refuel sequence for a GE Mark 1 system involves changing 1/2 of the fuel. So, I have assumed, on that basis alone, that REACTOR 4 contained 1/2 a load of UOX fuel. The assumption was that the replacement half, would either be UOX or more likely MOX fuel.

    I have also assumed that the FDU-4 Spent Fuel Pool contained ‘about’ 1 full load (two 50%) loads of new, (unirradiated) fuel. That would probably be about average.

    Various reports have indicated that the Fukushima Daiichi Nuclear Power Station has an (excellent) practice of moving older (>7.5 year cooled) fuel from the elevated Spent Fuel Pools, to the ground-level Common Spent Fuel Pool. So based on that reported fuel storage practice, I have assumed that the Unit-4 Spent Fuel Pool now contains about 8 years of Spent Fuel.

    Since TEPCO, Japan, USA, IAEA and the nuclear contractors LIE continuously; the ACTUAL fuel locations, dispositions, conditions and amounts are not provable. So we have to go with something, as a personal mathematic model.

    So my model is 1/2 load in the reactor and 7.5 years of Spent Fuel in the elevated pool.

    Sincerely,

    Bill Duff

    1. 7.5 Years Spent Fuel in the pool is ~ 1/4 of the total

      Some have pointed out that only about 1/4 of the expected amount of Spent Fuel has been shown in the films and photos. That suggestion would fail to undermine my personal model of 7.5 years Spent Fuel in these 35+ year old civilian nuclear power plants.

      These boilers and psuedo-contained scrap-heaps are GE Mark-1 defective, old, corroded, brittle, neutron-vugged-up, under-controlled, under-cooled, worn-out chunks of garbage. And they have sufficiently demonstrated the design deficiencies of the GE design, for the girls that I run with.

      Sincerely,

      Bill Duff

    2. According to the TEPCO handouts reactor four was down for maintenance and all of it’s fuel had been transferred to the spent fuel pool. There’s nothing in the reactor itself.

  5. Being the eternal optimist, I’m hoping that there is insufficient damage to the assemblies in all of the fuel pools to allow them a fighting chance to remove the fuel without incident.
    Hoping that the fact that we haven’t witnessed any molten mass burn-throughs of the bases of the pools after 2.5 years that would subsequently drain and….well, you can guess the resultant scenarios…. gives us some chance at least.

  6. Door Number 3

    The most concerning events occurred at FDU-3, which many assume to have been a nuclear explosion, with various caveats, conditions and nuances, an atomic bomb.

    Something, most likely radioactive Iodine (I-131), from Fukushima, tinged the Northern Hemisphere atmosphere BURNT-ORANGE. The vast, orange, radionuclide storm circled the globe, driven by the Jet Stream.

    I assume the atomic blast was initiated inside the MOX fueled FDU-3 Reactor. The yield was on the order of a ‘Davy Crockett’ Tactical Nuclear Warhead. And it was a VERY dirty bomb. The cooing assurances of the global nuclear cabal notwithstanding, the FDU-3 detonation, taken alone, was LIKELY the worst nuclear radionuclide dispersal in human history.

    The BURNT ORANGE atmosphere convinced me that the FDU-3 blast, literally DWARFED the total releases at Chernobyl. Hence all the lying from the global nuclear village.

    So I am HIGHLY curious about, what remains, inside the collapsed walls, of the FDU-3 nuclear power plant. How much went up? How much went radial (out)? And how much went to ground (down)?

    Sincerely,

    Bill Duff

    1. When the cores melted down they released their load of stored decay products. There was no atomic explosion.

      Your global iodine storm was barely detectable by the time it reached the west coast of the united states.

      We are all highly curious about the current state of all the reactors that melted down.

      1. All comforting childrens lullabies, and whistling by the graveyard, aside.

        The ENTIRE gawdamn sky, from Seattle-San Diego to BANGOR-Miami, turned BURNT ORANGE with radioactive Iodine.

        We have had a few volcanos turn the sky YELLOW with sulfur. And the soot from a burning Yellowstone National Park was visible over much of the North American Continent.

        The Fukushima Radioactive Iodine release was IMMENSE. No doubt the radio-cesium was awesome as well, but the cesium was invisible poison.

        We could SEE the radioactive iodine, for several days. Nothing in the atmospheric testing serial-kill was remotely so VISIBLE, at any distance.

        Sincerely,

        Bill Duff

  7. “The ENTIRE gawdamn sky, from Seattle-San Diego to BANGOR-Miami, turned BURNT ORANGE with radioactive Iodine.”

    Neat.

    You have a picture of course. Oh wait, you can’t have a picture because it’s not possible to take a picture of your imagination.

    1. The Village Idiot, V. I. Diemos fails (refuses) to recognize …

      That EVERYBODY in North America is a credible witness to the BURNT ORANGE skies of Fukushima. I am merely refreshing THEIR memory.

      There was a GREAT DEAL of discussion of the VAST Radionuclide Storm at the time.

      These gawdamn lies, and these gawdamn liars HAVE convinced me of one thing. SCIENCE is DEAD, until the nuclear village is ransacked and burned. So, I favor restoration of SCIENCE, at the express-expense of Team Nuke.

      Oh, and Diemos, how was your dinner with Ann Coulter and Dr. Brainwasher?

      Sincerely,

      Bill Duff

      1. You have a picture of course. Oh wait, you can’t have a picture because it’s not possible to take a picture of your imagination.

        I’m sure the sky turning orange was on all the news. Oh wait, it wasn’t, because it only happened in your imagination.

        1. It generally takes several years to bring war-criminals to the harsh justice. Lots of Nazis, collaborators and Japanese war criminals were frog-marched to the gallows and the firing squads. Sadaam Hussein and lots of others have taken the drop.

          That is the pattern and it will play out with Team Nuke, just as it does with the drug cartels.

          Just a matter of time. The wheels of God’s justice grind exceeding slow, but they grind exceeding fine.

          Looking forward to a happy day, picnic and round of beer, to celebrate the Team Nuke ‘Send Off’.

          Sincerely,

          Bill Duff

          1. Oh Bill, if you’re going to make stuff up you would stick to things that can’t be easily verified.

  8. I don’t recall the link, but Helen Caldicott was discussing the Orange Skies in a conference a while back.

    BURNT ORANGE sky was an interesting phenomenon (weather pattern).

    I did NOT take my KI pills, but DID increase my multivitamin to about 3+ per day from 311 until about April. Then gradually tapered off in the summer. Just an attempt to BULK UP on ALL the minerals to reduce the radionuclide uptake.

    Sincerely,

    Bill Duff

  10. I remember Arnie Gundersen saying they remove 1/3 of the fuel of the reactor during maintenance operation. Ask him personally, why not? Of course I don’t know either for sure, but consider there is fuel in reactor 4 since I heard Arnie give this information.

    I do understand the magnitude of the radioactive pollution since this summer only, knowing the density of B-radionuclides per liter and the daily flow of underground water. I found these informations here on Fukushima Diary, thank’s to you Iori.

    Then consider all the oceans are connected through their currents.

    Life on earth is threatened.

    Our next step is to find solutions to turn this radioactive energy into life supporting harmonics, that’s all.

    We need to find the tunings of our thoughts, colors, sounds,… that can orientate the radiations on life’s harmonics, it is mathematics and physics.

    Look for Tom Bearden’s findings to get a little push of hope that’ it is possible.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
