[Short Column] Where is the molten fuel ?

Note : Thank you for reading Fukushima Diary. Fukushima Diary is genuinely supported by your donation.
Monthly recurring donation is also appreciated.

 

People often ask me about where I think the molten fuel is.

I assumption is this, the fuel assemblies are entirely molten a few hours after the station power blackout in 311. When they vented the vessels, a part of the molten fuel splashed out of the primary containment vessels, could be even out of the venting stacks.

The rest of the fuel was scattered everywhere in the vessels and the reactor buildings due to the explosion. Some of them might be in the base concrete.
Currently those are moving with coolant water, and are in individual stages of fission reactions, which are small enough not to be detected outside of the plant area.

The decay power probably isn’t large enough to cause additional hydrovolcanic explosion anymore, but widely scattered fuel is making decommissioning more difficult.

Les gens me demandent souvent où je pense que se trouve le combustible fondu.

Mon hypothèse est celle-ci : Les assemblages de combustible ont complètement fondu en quelques heures en mars 2011 après la complète coupure de courant de la centrale. Quand ils ont aéré les enceintes, une partie des combustibles fondus a été éjectée de l’enceinte de confinement primaire et a très bien pu aller jusqu’à sortir par les cheminées d’aération.

Le reste du combustible a été éparpillé partout dans les enceintes et les bâtiments des réacteurs à cause des explosions. Il a pu en tomber un peu dans la base en béton.
C’est ce qui dérive actuellement dans les eaux de refroidissement, ces amas étant chacun dans un état de fission spécifique. Ils sont assez petits pour ne pas être repérés depuis l’extérieur de la centrale.

Leur pouvoir de désintégration n’est sans doute plus assez grand pour provoquer d’autres explosions hydro-volcaniques à présent mais cette très grande dispersion du combustible rend le démantèlement plus difficile.

  1. A very conservative fuel disposition

    This describes an extremely optimistic fuel location inventory.

    Unfortunately, much of the available evidence points to a wider fuel scatter. Rocket Fuel was scattered over a 1,000 Square Mile region. Evidence of fuel vaporization has been reported. Fuel chunks and fragments have been recovered and buried, perhaps up to 35 miles away. STEAM that periodically emerges from the ground in the vicinity of FDU-3, points to some fuel underground.

    The supersonic detonation of FDU-3 appears to have launched MOX fuel over a wide area.

    There are few competing explanations for the wide scatter of fuel fragments, besides the FDU-3 detonation.

    Sincerely,

    Bill Duff

  2. Steaming Hot

    The Fukushima Daiichi Nuclear Power Plant (FDNPP) disaster is comprised of Three (3) nuclear reactor total meltdowns due to loss of primary heat sink combined with a station blackout of AC electrical power. Containment was at least partially breached in all three explosions; and appears to have been totally breached in the FDU-3 detonation. In addition, according to USA Nuclear Regulatory internal communication, there were several FDNPP Spent Fuel Pool fires. Partial meldowns (core damage) likely occurred in other FDNPP reactors.

    FDU-3 core failure and explosion were accelerated due to (hotter) MOX Fuel. FDU-3 produced a supersonic detonation of substantially greater force than the subsonic deflagrations of FDU-1 and FDU-2. Chunks of Nuclear Fuel were scattered across a wide area; presumably due to the FDU-3 blast. Rocket Fuel (Pt-238), possibly the most carcinogenic substance on earth, was scattered over a 1,000 square mile area of northeastern Japan and the Pacific Ocean. Some of the scattered FDU-3 nuclear fuel appears to have been vaporized in the most energetic explosion of a civilian nuclear power reactor in human history.

    Sincerely,

    1. Rocket Fuel

      http www youtube com/ (watch?v=lIe-gWtQfl8)

      ENENews Headline Archive: at 4:36 minutes in, discussing Pu-238 (Rocket Fuel), presumably from FDNPS.

      Plutonium 238 is used in Space Batteries, such as Voyager, now entirely out of the Solar System in Deep Space.

      Pu-238, is perhaps the most carcinogenic material on earth. While any plutonium isotope can create a nuclear blast, Pu-238 is FAR too radioactive, for use as a bomb material. The radiation shielding would be too heavy for use aboard an aircraft or missile.

    2. Fukushima Daiichi Unit-3 Rocket Fuel Launch

      http ajw asahi com/ (article/0311disaster/AJ2011100112896)

      Ministry maps strontium, plutonium fallout – October 01, 2011

      At six locations lying either within a 30-km radius of the nuclear plant or beyond that radius to the northwest, however, the proportion of total plutonium consisting of plutonium-238 was much higher than in residual levels left by the nuclear tests, clearly indicating that the contamination was caused by the Fukushima disaster, the ministry said. Plutonium from the latest accident had previously only been detected on the grounds of the Fukushima No. 1 nuclear plant.

      Plutonium traces detected at 10 locations in Fukushima

      Plutonium believed to be from the Fukushima No. 1 nuclear plant has been detected at 10 locations in four municipalities in Fukushima Prefecture, the science ministry said. The highest reading was 11 becquerels of plutonium-238 per square meter, detected in the town of Namie, the ministry said Tuesday. That is about 1.4 times higher than the level that originated from fallout from nuclear weapons tests abroad. The other municipalities are the town of Okuma, the village of Iitate and the city of Minamisoma.

      The findings were from a survey in which samples were taken at 62 locations within 100 km of the stricken plant. No plutonium was found in samples from areas 45 km or farther from the plant, the ministry said. The ministry released similar investigation results last September that covered an area 80 km from the plant. This time, the ministry expanded the area to 100 km. In the latest survey, plutonium-238 was detected in 10 of 62 locations. The farthest point was in Iitate, some 32 km from the plant.

      1. The Pu-238 is scattered over an approximate 40 kM radius,

        This works out to ~ 3 Billion Square Meters, contaminated with Pu-238.

        Rocket Fuel does not work out too well in the lungs of children.

      2. “10 of 62” (Personal Statistics)

        Downwinders without breathing protection, within 20 miles of the Fukushima Daiichi Unit-3 explosion, inhaled plutonium (PU-238 – Rocket Fuel) about every 6th breath. The simple fact is that these downwinders can EXPECT a lung cancer diagnosis.

        These downwinders are victims of a KNOWN defective design, General Electric Mark-I ‘containment system’, which was deliberately UPRATED with MOX fuel, for a 15% increased electrical power output.

          3. Niall – Your Logical Fallacy is: ad hominem

            https yourlogicalfallacyis com/ (ad-hominem)

            You attacked your opponent’s character or personal traits in an attempt to undermine their argument.

            Ad hominem attacks can take the form of overtly attacking somebody, or more subtly casting doubt on their character or personal attributes as a way to discredit their argument. The result of an ad hom attack can be to undermine someone’s case without actually having to engage with it.

            Example: After Sally presents an eloquent and compelling case for a more equitable taxation system, Sam asks the audience whether we should believe anything from a woman who isn’t married, was once arrested, and smells a bit weird.

  3. Nuclear Fallout Victims

    http historytogo utah gov/ (utah_chapters/utah_today/nucleartestingandthedownwinders) html

    Excerpts:

    Within three to five years after atmospheric testing, leukemia and other radiation-caused cancers appeared in residents of Utah, Arizona, and Nevada living in areas where nuclear fallout had occurred. Communities in which childhood leukemia was rare or unknown had clusters of cases in the late 1950s and early 1960s. In the 1990s, people in Iron County believed that those who lived there in the 1950s were guinea pigs and victims, like the sheep. They have adopted the appellation “downwinders,” signifying they lived “downwind” of atomic tests. Tests were usually conducted when the wind was blowing east or northeast in order to avoid fallout over more densely populated areas to the south and west, including Las Vegas and southern California. Iron County is centered in the fallout arc. Even though it is impossible to prove that any particular person died or was afflicted by cancer caused by radioactive fallout, the perception of people living in Iron County is that atmospheric nuclear testing brought an epidemic of cancer to the area. The link between radioactive exposure and tumors can, however, be drawn statistically. There is also a local perception that infertility, miscarriages, and birth defects are part of the legacy of living downwind of nuclear tests. Long-time residents of southwestern Utah are quite comfortable blaming a multitude of medical problems on nuclear testing and wonder how many future generations will be affected.

    Even though House subcommittee hearings in 1979 found that the government was negligent, that fallout was a likely cause of both adverse health effects to downwind residents and the 1953 sheep losses, its report Health Effects of Low-level Radiation stated that a cause-and-effect link cannot be forged between low-level radiation exposure and cancer or other health effects. Since these might not appear for years or decades, the Federal Tort Claims Act is impossible to apply and compensation had to come through legislation.

    In 1979, congressional oversight hearings uncovered weighty evidence of AEC deception in 1956 and Judge Christensen reopened the suit. His fifty-six-page decision concluded that new information demonstrated that “a species of fraud” had been committed upon the court by government lawyers and federal employees acting “intentionally false or deceptive.” He also noted improper attempts to pressure witnesses not to testify, a vital report intentionally withheld, and “deliberate concealment of significant facts with references to the possible effects of radiation upon the plaintiffs’ sheep.” He set aside his prior judgment and granted the sheepmen’s motion for a new trial.

    The U.S. Tenth Court of Appeals, in what has been called a “grotesque episode of American jurisprudence,” rejected Judge Christensen’s findings, maintaining that the material from the congressional hearings was not admissible under the rules of federal procedure. In the opinion of the appeals court, “nothing new” had been presented and it could see no reason to overturn the judgment of the court twenty-five years before. In 1986 the Supreme Court refused to hear an appeal of the circuit court decision. By that time, the older-generation ranchers were dead or dying. Only two of the original families were still sheep ranching; all had suffered financial losses. Hope of ever recovering damages ended with the disappointing Supreme Court decision in 1986.

    Just doing what governments do.

  4. Oops, killed earth’s humans, for a space battery:

    http danv 50webs com/ (pu238) htm

    Part of what makes reprocessing so bad is the hazards of handling the radioactive materials involved. The processing involved in Np-237 Pu-238 production is vastly different. The hazard from fission-product is essentially nil, because there is no fission product involved. But Pu-238 is 247 times more toxic (by weight) than Pu-239. Both Pu-238 and Pu-239 are routinely handled with rubber gloves because the radiation is so non-penetrating. But a single dust speck of either one will cause certain lung cancer if inhaled. If Pu-239 dust gets loose in a room, then that room becomes uninhabitable, but if Pu-238 dust gets loose in a room, then the whole building becomes uninhabitable. That is the magnitude of the handling risk of this process. (Note, polonium is even more active, 231x more active than Pu-238. It is so energetic it has a reputation for not staying in the containers where it is put.)

    Oops, killed earth’s human population, just for a space battery:

    The planned uses border on insanity when sanely contemplated. If a space-probe such as Cassini burns up in earth’s atmosphere, it could kill millions. I’ve heard that the Environmental Impact Statement for one of these probes says that if it malfunctions in the worst way, then it could adversely affect one billion people. I’ve seen published statements minimizing the dangers of the probes. One of these “worst-case” analyses was calculated mistakenly using the data for Pu-239. It neglected to factor in the increased activity of Pu-238 relative to Pu-239. Because Pu-238 is 247 times more radioactive than Pu-239, a “lethal particle” of Pu-238 is only 1/247 the mass of a “lethal particle” of Pu-239. Correcting the worst-case analysis from Pu-239 to Pu-238: the same mass, optimally divided, would yield 247 times as many lethal particles and therefore 247 times as many fatailities, using the same statistics as the original. But an additional adjustment is needed: a particle 1/247 the mass has 1/247 the volume and therefore 1/6.27 the diameter. The smaller particle would fall about 6.27 times slower. That would multiply the fatal inhaled doses again by 6.27, using the original statistics. The two corrections mean a combined multiplication of 1549 times, , when translating from Pu-239 to an equal mass of Pu-238.

  5. Hello,
    Thank you Mr Duff. Where have all your detractors gone? Could it be the lying mealy mouthed pieces of human excrement have nothing to say? Hmmmm. Are they desperately trying to get their families to safety? Will they perhaps commit suicide? Let’s hope so. Cowards, lizard people. O Lord how I hate them.

    1. I’m Too Old to Die Young

      If life is like a candle bright, death must be the wind
      You can close your window tight and it still comes flowing in
      So I will climb the highest hill and watch the rising sun
      And I pray that I dont feel the chill till Im too old to die young

      Let me watch my children grow to see what they become
      Oh Lord, dont let that cold wind blow till Im too old to die young

      Now I have had some dear sweet friends I thought would never die
      Now the only thing thats left of them is the teardrops in my eyes
      If I could have one wish today and know it would be done
      Well, I would say everyone could stay till theyre too old to die young

      Let me watch my children grow to see what they become
      Oh Lord, dont let that cold wind blow till Im too old to die young
      Let me watch my children grow to see what they become
      Oh Lord, dont let that cold wind blow till Im too old to die young

    2. Project,

      My intention, in such matters, is to ‘work myself out of a job’.

      Recently the ACTUAL environmental activists, as opposed to ‘Watermelons’ and ‘Team Nuke’ members have clearly denounced the civilian nuclear power industry as any part of the global solution to energy and power needs. (Watermelons are ‘green on the outside, but REDS on the inside)

      When the ACTUAL professionals in science, medicine and engineering, as opposed to the ‘Team Nuke” whores are similarly ‘up-to-speed’, I will gradually move on.

      It is generally a positive sign, when the doom & gloom, Malthusians shut up. It is similarly a positive sign when voices, plans and alternatives from groups other than CORPORATISTS (Fascists), GAMBLERS (speculators) and COMMUNISTS (Marxists) are heard.

      Sincerely,

      Bill Duff

  7. Also,

    It is also helpful, when some elements of the Christian Church, pull their heads out of their ass, and BEGIN to address the critical issues of the day.

    So also, Judaism, Islam, Buddhism, Shinto, LDS, Scientology … and the rest of the ‘organized religion’ groups.

    So far, they are ‘silent as the GRAVE’ with respect to the Fukushima Daiichi Nuclear Power Station (FDNPS) epochal disaster.

    That is epochal in the GEOLOGIC sense of the word.

    Sincerely,

    Bill Duff

    1. Experience shows,

      Experience shows that these religious groups will be wrong, in their initial forays into the Fukushima Daiichi Nuclear Power Station disaster. (Money Talks so Team Nuke will dominate the discussion at first)

      However, a few may get it right, ‘from the get-go’. And over time, a substantial number will ‘get it right.

      It is notwithstanding the learning curve, and usual false starts, about TIME for them to begin, IMHO.

      Sincerely,

      Bill Duff

  8. Bill Duff, you should consider starting your own blog. Reason being, I’m not sure how many people are expecting to find your posts within each of Mochizuki-sempai’s posts and then have the patience to read through them. It also seems a bit like you’re ‘hijacking’ the comments section (?) even if your posts are good and accurate.

    1. Obvious, Lying, ‘Team Nuke’ Trolls are apparently blocked.

      I suppose that surveillance, harassment, personal attacks and threats, FROM ‘Team Nuke’ may have quelled the appetite of many to comment in any public forum. Certainly, I have decided to IGNORE those factors as has our host.

      Many, it appears, are more cautious. The bad reputation of ‘Team Nuke’ can be measured by the CELEBRATIONS, when their plants are shut down. It can also be measured by the high-handed tactics of ROBBING national treasuries of Japan, Europe, Asia and the Middle East to ALWAYS fund their ‘pie in the sky’ bye and bye schemes. Nuclear Power plants are NOT commercially feasible, and the science and scientists are habitually untruthful.

      For now, if you have something useful to add, contribute it. I am NOT preventing other insightful comments or voices. It is interesting to have a relatively ‘Team Nuke’ TROLL free zone on the VAST internet and Blogosphere.

      Sincerely,

      Bill Duff

    2. ‘hijacking’ the comments section (?)

      I understand what your saying
      Mr Duff does alot of posting.

      What I don’t understand is

      ” even if your posts are good and accurate.”

      You know if more people became “doers” like Mr Duff
      more truth would get out.

      Why put a limit on truth just because its from the same person.

      I wish EVERYONE would get involed as much as Bill does

      And lori isn’t “competing” with Mr Duff
      he wants the truth to get out.

      Seems to me lori isn’t upset with his number of comments

      Why start another blog if the goal is the same.

      We need to unite against
      as Bill calls them
      ‘Team Nuke’

      not each other

    1. Hammerheaded Nial

      Make your case, you scum-sucking POS.

      There are no shortage of posts, to use for evidence. Most are fully documented as to source, for reader verification and review.

      Until then, please feel free to ‘Go Screw’!

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.
