South-Central Colorado — Friday, Nov. 20, 2015

In the previous post, Nov. 19, 2015, “And ‘WHAT IF’… What if ‘criticalities’ have not yet completely ended at Fukushima-Daiichi?“, I added a screenshot, which was sourced from ENEnews’ Nov 5, 2015 post, with this headline:

In typical ENEnews-style, the last part “Recriticality discussed by Japan’s top nuclear official”, wasn’t actually ‘discussed’, it was flat-out denied and stated to be ‘physically impossible’.  And thát assertion is what I’m questioning in this post.

I wonder if it’s a semantic thing, and what may actually be happening would more correctly be called sub-criticalities.  I called them “fission flare-ups“, ’cause I don’t think the fission chain reactions are being sustained non-stop per se.   I suspect they come and go in waves, but I haven’t actually done much research to find out if that is even possible.  Apparently top officials of organizations that approved this mess say it’s impossible.  Should we believe them?  Believing them is what got us into this mess, isn’t it?  Think believing them will help us get out of this mess faster?   Given their track record of denial, their statement unfortunately doesn’t mean anything.   Before I continue, a word of caution:

DISCLAIMERComments  and support are welcome, but I will eliminate those I find either terribly unkind, unhelpful, misleading, overly commercial, or off-topic.   Due to my amateur-level of understanding and lack of academic training, this is going to be a bit of a ramble, a journey of learning, where I’m just sharing what I’m finding.  So… if you, the reader, consider yourself even less informed than me, I would be véry careful and not believe what I’m writing at face value, as -really- I’m just learning and sharing what I think I’m learning.   If you’re more knowledgeable and spot something in error, do please a comment.

Is it “physically impossible” to have ongoing nuclear fission reactions in the molten-down mess?  I’m not so sure that that is true.  I’m going to go out on a limb and see if I can find some clues that suggest it IS possible to still have fission happen almost a half decade later.  Now, I’m not a nuclear scientist.  As I’ve made clear before, I don’t even have a college degree.  This blog is just a journey, and it may contain errors.  This blogpost is merely my attempt to learn more about this issue.  Is it “physically impossible” for hot molten nuclear fuel to have criticalities?  See if I can walk myself through this….  I’m starting off with snippets of information that perhaps taken in all together will sketch possibilities and impossibilities.  In no particular order:

A breeder reactor is a nuclear reactor capable of generating more fissile material than it consumes. These devices are able to achieve this because their neutron economy is high enough to breed more fissile fuel than they use from fertile material such as uranium-238 or thorium-232.

So there are configurations with mixtures of nuclear fuel in which enough neutrons are created for the fission-reactions to continue without the need for new fresh fuel to be added.   More, even, there are configurations in which the amount of fissile material will actually grow over time.   Can those conditions come together after a mega-meltdown in which fresh fuel and spent fuel merged together to form a giant lava-like blob in which the heaviest elements would become more concentrated at the bottom of the molten corium over time?   These are questions the arise in my mind.

  • The decay chain of U-238 and Th-232, and you can see for yourself that some of the peculiar upticks of specific isotopes (such as Bi-214, Rn-220, Pb-210, Rn-222, etc.) of late are in there somewhere:



Th-232, with a few of its possible parents included in this excerpt:


  • What actually are ‘criticalities’ or ”fission’, and the “Effective neutron multiplication factor”?


In is a section that I found illuminating:

Effective neutron multiplication factor

The effective neutron multiplication factor, k, is the average number of neutrons from one fission that cause another fission. The remaining neutrons either are absorbed in non-fission reactions or leave the system without being absorbed. The value of k determines how a nuclear chain reaction proceeds:

  • k < 1 (subcriticality): The system cannot sustain a chain reaction, and any beginning of a chain reaction dies out over time. For every fission that is induced in the system, an average total of 1/(1 − k) fissions occur.
  • k = 1 (criticality): Every fission causes an average of one more fission, leading to a fission (and power) level that is constant. Nuclear power plants operate with k = 1 unless the power level is being increased or decreased.
  • k > 1 (supercriticality): For every fission in the material, it is likely that there will be “k” fissions after the next mean generation time. The result is that the number of fission reactions increases exponentially, according to the equation e^{(k-1)t/\Lambda}, where t is the elapsed time. Nuclear weapons are designed to operate under this state. There are two subdivisions of supercriticality: prompt and delayed.

When describing kinetics and dynamics of nuclear reactors, and also in the practice of reactor operation, the concept of reactivity is used, which characterizes the deflection of reactor from the critical state. ρ=(k-1)/k.   […]

In a nuclear reactor, k will actually oscillate from slightly less than 1 to slightly more than 1, due primarily to thermal effects (as more power is produced, the fuel rods warm and thus expand, lowering their [neutron] capture ratio, and thus driving k lower). This leaves the average value of k at exactly 1.  Delayed neutrons play an important role in the timing of these oscillations.

In an infinite medium, the multiplication factor may be described by the four factor formula; in a non-infinite medium, the multiplication factor may be described by the six factor formula.

Prompt and delayed supercriticality

Not all neutrons are emitted as a direct product of fission; some are instead due to the radioactive decay of some of the fission fragments. The neutrons that occur directly from fission are called “prompt neutrons,” and the ones that are a result of radioactive decay of fission fragments are called “delayed neutrons.”

The fraction of neutrons that are delayed is called β, and this fraction is typically less than 1% of all the neutrons in the chain reaction.

The delayed neutrons allow a nuclear reactor to respond several orders of magnitude more slowly than just prompt neutrons would alone. Without delayed neutrons, changes in reaction rates in nuclear reactors would occur at speeds that are too fast for humans to control.

The region of supercriticality between k = 1 and k = 1/(1-β) is known as delayed supercriticality (or delayed criticality). It is in this region that all nuclear power reactors operate.  The region of supercriticality for k > 1/(1-β) is known as prompt supercriticality (or prompt criticality), which is the region in which nuclear weapons operate.

The change in k needed to go from critical to prompt critical is defined as a dollar.” [end quote from Wikipedia, retrieved on Nov. 19, 2015, with my emphasis added]

What I speculate may be possible is that the “effective neutron multiplication factor, k” (described above) may still be oscillating between just above zero (where most neutrons get absorbed or escape and there’s just not enough neutron flux to cause fission reactions, or only very quickly ending chains) and de facto subcriticalities  (k < 1), where the molten-down blob cannot sustain a chain reaction either, but they do occur, and although they fizzle out too, these chain reactions don’t die out right away, and would be responsible for giving rise to fission and activation products.  Those in turn, when vented, would rise very high quickly due to their extreme heat and would be detectable in tiny trace amounts where jet stream wind patterns slow down.   (Or so goes my hypothesis…)   Perhaps every now and then a chain reaction may take off, and even grow for a little bit, but then the generated heat makes the fissioning area expand and the chain ends again.   What would make it start back up again is when there’s a sufficient amount of delayed neutrons from radioactive decay inside the blob.  I don’t know what the configuration of decaying isotopes, heat and density would need to be for this to be possible, but it doesn’t seem to be flat-out “impossible”.  It doesn’t even seem flat-out impossible for (sustained) ongoing-fission, either.  In the absolut worst case, some kind of “breeder reactor” would have been formed, but while perhaps not entirely impossible (?), that might be far less likely than some kind of k-oscillation that includes fission flare-ups.

On the Woods Hole Oceanograpic Institute’s website there’s a video with really bad audio (@, in which top experts made some remarkable statements (after 38 minutes in), as relayed by ENEnews on October 27th, 2014.  I listened and the transcript is correct:

Of course, if the fissioning didn’t stop, as is pretty darn obvious from the releases of I-131 that went on for much longer than they should have, then that means that the molten-down lava-like corium had a nuclear fuel configuration (fuel, spent fuel, decay products, heat, density, amount,…) that allowed for the neutron flux to get intense enough in an medium with plenty of fissile fuel to cause -at least- subcriticalities.  Could as well call ‘m “criticality flare-ups”.   What if the corium/coria melted down deep enough to be so too far out of reach, or utterly unapproachable, that any added boron, graphite, or other neutron absorbers simply never even have reached the problem section of the corium?  And thus, what is so “impossible” about ongoing criticalities, still, now in 2015?

What if the neutron flux was so insanely intense in the first week or weeks of the disaster that it altered the composition of much of the fuel that melted down.  What if that irradiated mixture of new decaying products and various activation products, which due to their decay also changes composition over time, are now actually creating a sector inside a corium that is volitile enough to see renewed cycles of subcriticalities?

I found this interesting EuroSafe document, “Criticality Safety in the Waste Management of Spent Fuel from NPPs” by Robert Kilger:

In it is a graph I find quite amazing: due to the decay of radioisotopes, the effective neutron multiplication factor, k (described above), creates an oscillation over thousands of years, with k going up and down depending on which isotopes are in which stage of their decay.  The time-scale is logarithmic:

Pondering over this made me wonder: are there also radiosiotopes that emit lots of neutrons as their mode of radioactive decay?   Turns out, yes: Californium-252 is an example.

Cf252Now, is it possible that additional Cf-252 was created at Fukushima?  It would likely have happened during the early heavy neutron bombardment period, and thus some of this Cf-252 may have ended up in the molten coriums.  Seems rather plausibe, actually.   So, IF that were the case, then the neutron-spewing decay of Cf-252, in an environemnt full of some of the heaviest isotopes of Uranium, Pluonium, Neptunium, Americium, etc. of all places, would certainly cause some fission reactions, wouldn’t it?  I mean, that’s apparently one of the ways fission reactors are started up.  What if some kind of subcriticalities-no-subcriticalities oscillation has been occuring?    I have yet to learn more about the kinds of barns not used for stacking hay in to see if this is mathematically possible, but it seems this would be one way to end up with a neutron source in the rubble that didn’t just go away.

I think it’s possible, because:  Spent (irradiated) fuel rods always contain Plutonium, and on top of that, Unit 3 contained MOX fuel (mixed oxides of Uranium and Plutonium), and thus, most likely, a lot more Plutonium was present in this meltdown than in any nuclear meltdown accident in the past.

I read that when Plutonium is irradiated, you end up with Curium, and if you bombard Curium with alpha particles, then you’ll end up with some Californium.  There was Plutonium, there was heavy neutron bombardment, and there was and still is tons of alpha decay going on, so no shortage of alpha particles either.

This should shed some light on how significant it would be to have Cf-252 in the rubble:

From “Californium-252, an isotope with a half-life of about 2.6 years, is a very strong neutron source. One microgram (0.000001 grams) of californium-252 produces 170,000,000 neutrons per minute.

Would it be possible to start out with Pu-239/240/241 and in an extreme neutron bombardment environment end up with at least a little bit of Cf-252?  That’s seems quite the step-up…  But there didn’t seem to be no shortage of neutrons nor alpha emitters, and there were many TONS of fuel that melted down, so… why not?

Let’s see… Synthesis of Curium (via Wikipedia):

To recap, there’s two ways to end up with curium in a neutron bombardment environment: :  Uranium-238 turns into Curium-242, or Plutonium-239 turns into Curium-244.

– When Uranium-238 is bombarded with neutrons this leads to the creation of some Curium-242 by way of a double neutron uptake and a beta decay in these steps:

  • U-238 + neutron -> U-239
  • U-239 + neutron -> Am-241
  • Am-241 beta decays to Cm-242

Or, Plutonium-239 is bombarded with móre neutrons and this leads to the creation of some Curium-244 by way of these steps:

  • Pu-239 + neutrons -> Pu-243
  • Pu-243 beta decas to Am-243
  • Am-243 + neutron -> Am-244
  • Am-244 beta decays to Cm-244

In addition:

  • Cm-244 in turn alpha decays to Pu-240    (The main decay chain goes: Cm-244 -> Pu-240 -> U-236 -> Th-232 ->Ra-228 -> Ac-228 -> Th-228 -> Ra-224 -> Rn-220 -> ect. to stable Pb-208, and a side-decay-branch to stable Pb-206.)
  • Some Cm-244 + neutrons -> Cm-247, Cm-248, …

So, given the heavy neutron bombardment in the beginning, it is near-certain that some of both Cm-242 and Cm-244 were created in the molten corium.

Now how would one get from Cm-242 or Cm-244 to Californium-252?  Well, it says here, @

Prolonged irradiation of americium, curium, and plutonium with neutrons produces milligram amounts of californium-252 and microgram amounts of californium-249.

and: “As of 2006, curium isotopes 244 to 248 are irradiated by neutrons in special reactors [or under similarly conducive conditions?] to produce primarily californium-252 with lesser amounts of isotopes 249 to 255.   […]   Three californium isotopes with significant half-lives are produced, requiring a total of 15 neutron captures by uranium-238 without nuclear fission or alpha decay occurring during the process.  Californium-253 is at the end of a production chain that starts with uranium-238, includes several isotopes of plutonium, americium, curium, berkelium, and the californium isotopes 249 to 253 (see diagram):

Well, to repeat from above, you only need 1 microgram (0.000001 grams) of Cf-252 to produce 170,000,000 neutrons PER MINUTE.  (That information is reportedly found in The encyclopedia of the chemical elements, edited by Clifford A. Hampel. Published/Created New York, Reinhold Book Corp. [1968] Library of COngress # 68029938.)

We know for a fact that there was a substantial amount of Plutonium isotopes in the mess that melted down, particularly at Unit 3.  Even though this is a very heavy element that is not volatile like iodine, tellurium or cesium, it was nevertheless even detected many miles from the Fukshima-Daiichi disaster site.  –> See, for example, the scientific evidence in the article, Isotopic evidence of plutonium release into the environment from the Fukushima DNPP accident  (Nature, Scientific Reports 2, Article number: 304 (2012) / doi:10.1038/srep00304  pubished online on March 8, 2012.).

From the same aforemention EuroSafe document, with Cf-252 added by me:


Given how heavy Cf-252 is, it likely concentrates at the bottom of the molten corium with all the other fission-prone heavy weights…  and, so I speculate, this could be one way of ending up with subcriticalities long after they “should have ended”.  So, what if, at least in the beginning, enough Cf-252 was created that its neutron-spewing presence continues to create both neutron activation products (perhaps even contributing to the peculiarly high presence of activation products Co-60 and Sb-124/125 ?), as well as fission events, giving rise to trace amounts of I-131, Cs-134, etc.)

So, in short: it doesn’t seem impossible whatsoever.  It all depends on what happened in the beginning.  Was there, or was there not what could be called an EXTREME heavy neutron bombardment environment when the Fukushima-Daiichi nuclear catastrophe began?  All evidence points to that having been the case.

According to “Geochemical Journal, Vol. 46, pp. 335 to 339, 2012: An estimation of the radioactive 35 S emitted into the atmospheric from the Fukushima Daiichi Nuclear Power Plant by using a numerical simulation global transport” [H/T ENEnews, Jan. 13, 2015], the neutron flux that reached the seawater injected in the reactors emitted “5.2 × 1021 slow neutrons m–2 sec–1″ [m–2 sec–1 = per sq. meter per second].

Neutron flux levels deeper within the molten corium(s), which the injected water perhaps never even reached (as the high heat evaporated the water long before it could get close, I recon) may have been faster and/or reached significantly higher levels.

Seems rather possible, if not quite plausible, to have ended up with some Cf-252.  Over 25% of the Cf-252 created in March-April 2011, would still be present in the molten corium, even if no additional Cf-252 was created since  (Cf-252’s half life is 2.64 years).

  • I had a look back at some of the data in my lichen and rainwater samples I had analyzed in June (2015), and re-read a few things in the related blog posts.  Among the ones flagged ‘unknown’ are a few that stood out significantly above background, such as these in the lichen sample, about which I wrote, (see below this raw data sheet):

At the time, July 10, 2015, in “An Attempt to Identify the ‘Unknown’-Flagged keV Decay Energies in the Lichen Sample Gammaspectroscopy“, of the 3 most pronounced unknown detections, I wrote the following about the second (the 77.06 keV signal) and the last highlighted (the 1765.12 keV signal); [edited w/ new emphasis):


  • 77.06  keV    —>  Antimony-122 (intermediate decay state Sb-122m)

Because 76.0595 keV sure rounds nicely to 77.06 keV.    SOURCES:

Again… that neutron activation weirdness.  What’s up with that?  See also the mention of Sb-122 in 

To quote, “[…] Relatively few of the bomb fallout isotopes come from nuclear fission. In fact, most radioactive materials in a bomb’s fallout are caused by the process called “neutron activation”. Neutrons are the only type of radiation that can make other atoms radioactive. The soils, buildings, and other materials pulverized by a bomb’s explosion are instantly engulfed in the neutron field caused by the detonation, making radioactive isotopes from those elements that were not radioactive before the blast.

Some of the prominent bomb-fallout isotopes are Sodium-24, Chromium-51, Manganese-54, Iron-59, Cobalt-60, Copper-64, Antimony-122 and Antimony-124, Tantalum-180 and 182, and Lead-203.(1) The half-lives vary from as low as 8 hours (Ta-180) and as long as 5.3 years (Co-60).   Just for the record, a small amount of Carbon-14 is formed by the bomb, but its quantity is miniscule. Regardless, none of the bomb-fallout isotopes listed above are produced by power plant reactors.  By comparison, bomb-spawned Cs-137 is literally a trace relative to the volumes of the above-listed bomb fallout isotopes. […]”

AND, perhaps the strongest detection:

  • 1765.12  keV  —>  Bismuth-214 (Bi-214)



It’s taking me some time to take in and grasp the significance of all these bits and pieces…  I didn’t know yet about the significance of Bi-214 back then.  I was starting to get onto it this spring when looking into the Chernobyl wildfires (See May 2, 2015, “(More ADDITIONS) Bismuth-214 as a Fallout Indicator? Systematic Omissions: More Evidence of EURDEP Hiding Data when it Matters Most…“), but like so many snippets of data and news from here and there, it had already forgotten about Bi-214 when one of its more rare decay energies appeared flagged as unknown in my own data.  Not just mere part of “natural radon progeny”:  Look at the higher parents in the decay chains its part of in  Anyhow…  Here’s what I’m looking at:

We got the recent Finnish and German detections, both in spring 2015 and just recently in October 2015 with quantifiable validated detections of Cobalt-60, Manganese-54, Actinium-225 & 227, Cesium-134 & 137, Zirconium-97, and Thallium-202.

In my own rainwater and lichen samples (See Aug. 1, 2015, “Synopsis / Improved Version: ‘Mainland USA June 14 2015 Radioactive Rain & Lichen Data Revisited,’” as uncertain as they are, there is still a faint signal that suggest trace precence of  Antimony-124,  Strontium-89, Ruthenium-106, Cesium-134/137 and even Iodine-131 and  Cobalt-57, and with the unknown-flagged ones included, also Antimony-122, probably more Bismuth-214 than thought, and a bunch of traces of very unusual ones.

Half of those detections here as well as in Europe are activation products more associated with a nuclear bomb detonations.  That may seem bizarre, but it’s not to be dismissed.  Here’s another thing I haven’t written much about… I guess I do actually truly suffer from forms of ‘cognitive dissonance’ myself at times.  There are some things I have a hard time accepting, just due to associations and implications that I don’t really want to accept.


One of these things that I have had a hard time accepting is that:  It is quite likely that one of the explosions at Fukushima-Daiichi, the one at its Unit 3, was not a mere hydrogen explosion, but -for real – a prompt criticality (a mini, but actual nuclear explosion).  It appears that the detections actually confirm this further.  The nuclear blast at MOX-filled Reactor Unit 3 at Fukushima-Daiichi  did mainly 2 things:

1) The blast blew an unprecedented amount of nuclear fuel sky high, of which an unknown amount fell or washed out into the Pacific Ocean; &

2) the blast sent out a very intense massive neutron flux at the time of detonation, which  irradiated the rubble, creating all kinds of activation products and nuclear transmutations that dramatically altered the coriums that melted further down.

Some sources re. likely ‘nuclear explosion’ @:

Quoted from the latter, TIME Magazine online Science section, March 30, 2011:

“[…] Tokyo Electric Power Company (TEPCO) had observed a neutron beam about 1.5 km away from the plant.  Bursts of neutrons in large quantities can only come from fission so Dalnoki-Veress, a physicist, was faced with an alarming possibility: had portions of one of Fukushima’s reactors gone critical?

To nuclear workers, there are few events more fearful than a criticality accident. In such a scenario, the fissile material in a reactor core–be it enriched uranium or plutonium–undergoes a spontaneous chain reaction, releasing a flash of aurora-blue light and a surge of neutron radiation; the gamma rays, neutrons and radioactive fission products emitted during criticality are highly dangerous to humans. Criticality occurs so rapidly–within a few fractions of a second–and so unpredictably that it can suddenly kill workers without warning. There have been 60 criticality incidents worldwide since 1945. The most recent occurred in Japan in 1999, at an experimental reactor in Tokai, when a beam of neutrons killed two workers, hospitalized dozens of emergency workers and nearby residents, and forced hundreds of thousands to remain indoors for 24 hours.

Dalnoki-Veress did not see any further reference to a neutron release. But two days after the Kyodo agency report, on March 25, TEPCO made public measurements of different isotopes contributing to the extremely high measured radioactivity in the seawater used to cool reactor No 1. Again, a piece of the data jumped out at Dalnoki-Veress: the high prevalence of the chlorine-38 (Cl-38) isotope. Cl-38 has a half-life of 37 minutes, so would decay so rapidly as to be of little long-term safety concern. But it’s very presence troubled Dalnoki-Veress. Chlorine-37 (Cl-37) is part of natural chlorine that is present in seawater in the form of ordinary table salt.  In order to form Cl-38, however, neutrons must interact with CL-37.  Dalnoki-Verress did some calculations and came to the conclusion that  the only possible way this neutron interaction could have occurred was the presence of transient criticalities in pockets of melted fuel in the reactor core.

[…] he published those calculation in a paper for the blog ArmsControlWonk. The paper makes clear that if a criticality accident occurred at Fukishima, it could happen again […]”

The study, “WHAT WAS THE CAUSE OF THE HIGH Cl-38 RADIOACTIVITY IN  THE  FUKUSHIMA DAIICHI REACTOR #1 -F. Dalnoki-Veress, March 28, 2011” is found @

I may be slow, but at least it is beginning to sink in…  And maybe my hunch has been right all along…  (See also June 2015’s Radiological Emergency – Northern Hemisphere – RED ALERT !, or further back, July 31, 2013, Red Alert – Fukushima-Daiichi NPP Crisis: EXTREME Radioactive Water Leaking into Ground; Unprecedented Radioactive Contamination of Pacific Ocean.

So… come to think of it….

  • The early TEPCO data from 2013, with massive amounts of Co-60, Mn-54 and Sb-124 in stored contaminated water is more consistent with the effects of a nuclear bomb blast rather than a normal meltdown. (Screenshot of that data in here)
  • My very own detection of Co-60 in a Japanese Kelp sample (see here), while Cesium-134/137 was not detected in that sample, is more consistent with the effects of a nuclear bomb blast rather than a normal meltdown (see quote above in green sourced from here).  Same with my detection of Sb-124 in Colorado rainwater (see here) that likely blew in with the jet stream from Japan.
  • Both the Finnish and German detections in Spring and Autumn 2015 (see here), including traces of Co-60, Mn-54, Zr-97, make more sense when Fukushima is still releasing radiosiotopes from highly irradiated coriums that are still fissioning at times.

My tentative conclusion:   

  • 1) It is totally POSSIBLE to have ongoing criticalities 5 years later.
  • 2)  You can’t say that it’s impossible unless you know all the details of the make-up and conditions inside the corium.  They don’t know these things.

I think they are operating in some sort of a panic, as this disaster is evolving in uncharted territory, and they’ve chosen early on to have a specific narrative (primarily to protect financial investments), a completely bogus narrative it turns out, but it seems they aim not to deviate from it, even if evidence mounts that they’re lying.

Meanwhile the mystery carnage continues…

    Although you’ve likely already seen this, perhaps the title blurb of this piece from yesterday might as well read- ” 337 Whales BLeached in Largest Stranding Ever” –
    More guidance here- (…also see preceding comments)
    Have a great weekend.

    • MVB says:

      Tx Andy. I had not seen that. That probably means they turn pink when they decompose and the ones in BC had been there for awhile as well. I had not seen pink dead whales like that before, though. I thought it might mean something, like a clue to what killed them, but perhaps it doesn’t.

      Strange they suspect red tides. Can’t see where they would have evidence for that. Waters all around the coasts of Antarctica and a large patch west of Chile have been actually been signifiantly colder than average, and much of the Chilean coast pretty much normal.

      Current temperature anomaly map shows what has been the case for most of this year (including that “warm blob” in the Northern Pacific) @

  2. MVB says:

    Look closely at the k graph of spent fuel over 10,100,1000,10000,100000 years, the effective neutron multiplication factor, k, fluctuates between 0.91 and 0.96 Pretty darn close to 1. And that’s just for carefully removed spent fuel under normal conditions. A mega-meltdown including fresh fuel + spent fuel, + some of which got extra-irridated in the first week of the catastrophe, thus including radioradioisotopes (perhaps even Cf-252) normally not found in spent fuel nor new fuel in the elevated concentrations, and voila, the possibility of ongoing criticatlities is REAL.

    It cannot be dismissed off-hand as “physically impossible.” Obviously IT HAPPENED, at least well past the time it shouldn’t have happened, as evidenced by the late I-131 detection at Fukushima all the way into Summer 2011, as well as the Cl-38 concentrations, etc. Far more recent detections of odd traces (recent fission and activation indicators) in Finland and Germany could very well be part of ongoing releases that point at recurring recriticalities.

    The nuclear industry is willing to take those insane risks because of an apparent regulator’s mentality that seems to consider “highly unlikely” close enough to “not gonna happen”.

      That particular illuminati recruiter is still active on FD Cbox, btw. That is one that unrighteously brings many into ill-repute by attempting to color us all as “harmful rumormongers”, when it appears to be one of the ill(uminati) mongering harmful rumors.

      Loose N seems pretty pissed at me for having outed TF. C’est la vie, c’est la guerre.

      Have recently found a comment by Sickputer that confirms diem. relation w. MFX, the pr0n poster.

      Anyway, now i have to apologize to YOU and your readership for having apologized to that fokker. Wishing i had seen this months ago. Will quote there at later date.

      I thank you for properly (officially: “Entertaining”; unofficially: “Informing”) us all!

      PS: have you seen my work concerning Gravatar & Enformable’s ongoing outing of commenter email addresses? Do a Goggle search with terms “” (or “@yahoo”), etc. (Internet Archive research shows this started around Jan 2014, yet includes email add. of commenters from when his blog started!! I informed “Whitey” back in Nov., only to be ignored, and censored, despite utilizing proper English & avoiding accusation &/or profanity)
      Seems like he is still outing CaptD & JoyB, etc. Even if he isn’t directly from his web site, the info is most likely still being parsed from Internet Archive (etc)!!!!

      Yet it is that i have been thusfar unable to find any of the “Hall of Shame” having posted ANY commentary there! Did they all get the same memo, or what???

      Anyway, Dank u Meneer VB!!! Keep up the good work, sir!

        Hi Dud,

        I’ve kinda given up on trying to figure out the whole spectrum of disrupters, agent provocateurs, informants, bait setters, mappers of what little is left of the anti-nuclear movement, etc… I even have doubts about some supposedly respected voices in the ENEnews crowd.

        I did see the email outing thing mentioned in an enenews thread, I think.
        Some folks consider it a problem that this site has ‘Gravatar’ as well, right?
        I don’t quite understand the problem with Gravatar, haven’t looked into it.

        When I consider someone “a troll” (of any stripe), generally I ignore them. I find people who engage trolls almost as suspicious as the more obvious trolls themselves. Once you see that something’s off, and have pointed that out, why then still engage? How many comment threads have been feled at ENEnews with stupid back and forth bickering, just trolls and anti-trolls… doing their dance. See also some writings on that topic by Hatrick Penry @

          Hello, again.

          Quote: “I did see the email outing thing mentioned in an enenews thread, I think.”
          Respectfully, no, i don’t believe that you have. How would i know? I view ENE offline. No news on that front there on ENE, as far as i could ascertain via offline search. Noted the observation to you some months ago, yet it might have been overlooked as you have other matter on mind and that is understandable.

          The fact that you use Gravatar in of itself is not ‘the’ problem, although it has been noted (2009) that such hashes should be “salted” by adding random characters before MD5 hash generation (not yet certain how this is done, exactly) to further obfuscate related personal information, aiding prevention of disclosure.

          Enf. publishing email addresses of it’s commenters seems like a doozey of a problem though. They are searchable via ‘Goggle’, yet not many other search engines, as far as i’ve observed. (Noted that DuckDuckGo & Startpage/IXquick seem to have been neutered since at least early April (march?).)

          [quote] “I find people who engage trolls almost as suspicious as the more obvious trolls themselves.”
          After having engaged a few over the last couple of years, i must reflect my utterly wasted time coughing up any pearls before swine as “an agonizing ordeal, like balancing a pot of scalding water on your head while people whip your legs and butt.”

          Anyway, i’ll keep this short, as i see you are busy trying to protect many from “nukular” fallout of some kind, and i sincerely Thank You.

          1) How has Neutron Flux been?
          [quote] “Earth’s “Magnetosphere” COLLAPSED in space TODAY for two+ hours!” (h/t to JD for link)
          [quote] “NASA confirmed the incident was a software glitch — and that such fluctuations aren’t doomsday events.”
          OK, that might not be the most relevant avenue to follow, as the first article seems busted.

          2) Could aggregates from wildfire smoke make detection easier by giving such stuff a surface to “Klingon” to?

          (not looking for “instant gratification” answers, just passing along as they caught my eye & thought maybe somehow connected??? Am hoping you find answers for all.)

          Respectfully sir, here is where i first reported “Enformable-Email-Gate” to you:

          Self-quote: “Is it paranoia to be concerned about others?
          I remember you are not prone to paranoia, from earlier reading.
          Just be careful. I hope these things help you and others achieve that in the face of opposition. Be NOT afraid, be proactive.

          “An ounce of prevention is worth a pound of cure” – Benjamin (son of my right hand) Franklin (free).”

          It is still with thanks to you that i write, even if facing “friendly-fire” &/or suspicion.
          It is not mine to criticize you, nor to be belligerant, nor to let pride override humanity, but to dare to try to imagine walking a mile in another’s shoes, in my humble opine.

          I know you must have a lot on your plate so-to-speak, yet at some point over the next month, please try to confirm any of the findings faithfully presented to you.

          (Quote: “* We call them “useds” rather than “users” because Facebook is using them, not vice versa.” – )

          Dated 2009-12-08 !!! –

          Email-Gate “Exhibit: A”: (from Jan 29, 2014)
          CaptD’s (former, i hope) email address is there. Load the page, right click on a commenter’s avatar image, then select “View Image Info” (Firefox). Look at “Associated Text” & voila! An alternative might be to do a simple save of the page & open it in a simple “notepad” application to search for “” (etc).

          If you do not believe me (& i don’t blame you whatsoever if you don’t), ask “morph” next time he posts a reply on your site.
          Quote from Mochizuki’s Cbox: “22 Jan 16, 12:11 PM morph: dud, first i didn’t get the problem you described about wordpress pages. but after looking at the source code of the page” [Firefox – Highlight area, then Right-Click & select “View Selection Source”] “, i got it.. bad piece of software.. on the other side, i don’t use any “important”/private mail addresses when commenting on pages” [sage advice, imho]

          Witness#2: Quote of Stock: “I did the “view” trick and was able to divulge multiple personal emails at Enformable. Beyond annoying.”

          Am NOT looking for you to do an article, just FYI.

          What could one do with merely an email address? IDK. Yikes!!!

          Further: comment by antipathy: “Researchgruppen refers to itself as “the Swedish Stasi” and judging by their behaviour their aim appears to be absolute control of the social\political narrative.” Does that sound typical of any OTHER group? Hmmm.

          Apparently, ~191 million American voter records effectively leaked via a MongoDB database exposed to the public that didn’t seem to require a password to access.
          Add ~93 million Mexican voter’s privates exposed –
          That’s only for North America (or, as i like to call it, N/A)

          Quote: “What Data Are in a Voter’s List?” … “first and last name, your home and mailing addresses, your date of birth, gender, and ethnicity, the date you registered to vote, your telephone number, your party affiliation, your e-mail address if you provided one when you registered, your state voter ID, whether you’re a permanent absentee voter, and whether or not you’re on the Do Not Call list.”
          … “But for the most part, not only can political organizations acquire information about you, they may be able to post it publicly, or even create an app with the information.” … “A database with information on all American voters, for example, might go for about $270,000, according to one marketing firm consulted by researcher Chris Vickery.”
          Chump change for a organization like the “Nukular” Industry!

          Wait … that’s not all, folks! Quote: “This one, however, not only includes some states’ voter lists, but it also includes 19 million profiles with private information on religion, household values, gun ownership and more. Are you outraged now?”

          Perhaps your unfortunate experience November of last year might assist him in at least deleting that private info from Internet Archive (& perhaps other web libraries), if you are so inclined, as you seem to have special knowledge of how that might be accomplished. If a criminal act was committed in releasing those email addresses, well then – you shouldn’t help him!

          One thing i do recall about the real Stasi, was that they were eventually outed!
          “East German Police Officers Who Aided the Stasi”

          Perhaps you now have a better understanding of why i started downloading web pages for offline viewing. It is NOT for public exhibition nor for redistribution, but for education/research purposes & also to reduce my “attack profile” so as to reduce the odds of being hacked.

          Anyway, thank you for exposing inEPTCO’s incontinece, flaring & mental frailty – not to mention the wide gaping holes between their ears (they call it a brain).

          I will respectfully stop publishing comment here until you have had time to review the evidence presented so-far, if that is what you decide to do. By then, it will be 7 months since this was first uncovered. Am not into instant gratification though. Until then, i hope you are well in body and spirit.

          Sincerely, the original dud.

            Hey DUD, skimmed your comment (there have been so many loooong comments lately, that I didn’t even read many that I approved…)

            I have no issues with your or your comments. I’m just not that interested in the troll outing scene. It takes too much time away from things I find more interesting or pressing.

            Can you in just a few paragraphs tell me what you wish I did. You’re pointing at an issue with Gravatar.

            Any breach of privacy is an issue. I try to protect people’s privacy, and have posted comments annonymously at people’s request. I get that Enformable had a privicy of commenter breach issue (right?).

            But what I don’t get is what you want me to do, if anything? Acknowledge the issue, dig into it, spent my time reading all those liks that document that there’s been an issue,… change something about my blog?

            I’m not “playing dense” on purpose here. I don’t understand where I’m erring somehow.

            You write, ‘ If a criminal act was committed in releasing those email addresses, well then – you shouldn’t help him!”

            WHO? How? Don’t assume I understand. (I don’t actually) Can you point it out, in precise exact language without 14 links what the issue is with me or my blog? If there’s a procedure to be followed to address a privacy or related issue, can you lay it out, simple step by simple step?

            “please try to confirm any of the findings faithfully presented to you.”

            Which finding specifically? I have nothing to do with Enformable. I don’t use facebook. And this free WordPress blog came with Gravatar.

            Are you recommending I switch to a different blog site? if so, can you make that a little clearer, ’cause it’s NOT clear to me what you’re ultimately might be try to suggest…

            (No, I won’t go explore 14 links just because you threw them my way. Please clarify your intent and the gist of what you’re trying to say. Tx.)

            @ dud – If you left another comment, it automatically went to spam for reasons not apparent to me.

            While the IP address remained the same (out of east of Vancouver in BC, Canada ?),
            the websites you list as yours aren’t yours, and your given email keeps changing.

    I don’t have special know-how on that. I don’t know how my backups were erased from the Web Archive. It was all part of what seemed like my site was being messed with. It happened right at the time I had disappeared my own site. I changed my mind and it remains visible. But the Web Archive thing, or how traffic seems manipulated depending on the country I write about, and such. I have no idea if it’s dulusional imagination on my part, or super-creepy NSA web powers.
