Report: Neptunium-239 found in soil about 40 km from meltdown — “Several thousand becquerels” — Similar to levels detected at front gate of Fukushima plant

Published: August 15th, 2011 at 6:56 am ET


Neptunium-239 Detected from Soil in Iitate-mura in Fukushima???, EX-SKF, August 15, 2011:

[…] In their blogpost on August 11 (in Japanese), they relate their talk with a researcher at the University of Tokyo who has submitted a scientific paper to a foreign academic society. […]

[H]e tells the couple that he found neptunium-239 in Iitate-mura, about 38 kilometers from the plant, in approximately the same amount as he found at the front gate of Fukushima I Nuclear Power Plant. That is the topic of his paper.

The couple says in the very intelligent post that they cannot provide details because the paper is in review (but they also say the researcher has given them permission to talk about it in general terms), but it was in several thousand becquerels. There is no mention of whether it was per kilogram or per square meter or per something else. […]

Neptunium-239, gamma emitter whose half life is about 2.4 days, decays into plutonium-239 whose half life is 24,200 years.

If this Tokyo University researcher went to Iitate-mura after April 20 and he was still detecting neptunium-239 whose half life is only 2.4 days, I just abhor to think of the implications. […]

Read the report here.

    Isotopes of neptunium
    Neptunium 239 has a half-life of 2.356(3) days

    • arclight arclight

      it would appear that this becomes weapons grade plutonium 239 after it has degraded! 🙁
      and that maybe the distance qouted is wrong!
      how long will the paper mentioned take to be reviewd? has there been any recent testing in Iitate-mura for plutomium (the neptunium takes about 40 or 50 days to convert?) 🙁

      • arclight arclight

        if its a product from uranium then it was from one of the other 2 reactors! so wheres the plutonium from number 3? am i missing some obvious scientific point here?

        • arclight arclight

          in fact if which way was the wind blowing when the buildings exploded?

          • Morning Anne and Arclight

            I’m a bit fuzzy this morning but this article is saying that ongoing fission must be occurring in a major way is it not for that much Neputunium to be found so far away?

            Or is it possible that this really is from the March explosions?

            If it is from the March explosions, the volume of radiation that exploded must have been far greater than what were told, No?

            I appreciate all your comments…

          • arclight arclight

            @ maja
            yes i believe they are from the march explosions but unsure as to it coming from mox 3! but i remeber the point that all the reactors were running on putonium… unless they found plutonium as well as neptunium that could make sense, however if only neptunium 239 then maybe some weapons grade experimentation was going on…we will have to wait for the report to clarify this point maybe, unless anyone else has any angles to get the data?

          • bigisland bigisland

            When I first heard Reactor 3 had MOX fuel and called upon my physics friend to bounce such off him, the first thought was, OPPS, if this was a secret that Japan is doing weapons, well now the US and everyone knows. We then went on to speculate that perhaps it wasn’t a secret among the Japanese military over the hill running Daini Nuke plant and the Japanese mafia and the Yakuza who could be making the sales. Interesting Tokyo Gov spoke of “divine retribution”. Raised our eyebrows that something fishy had been going on.

    Iitate-mura looks more like 70km or more from the plant! i had a quick look, maybe i misgauged the distance ! but it looks more than fifty km!
    bit of a cut and paste

    “Twenty neptunium radioisotopes have been characterized, with the most stable being 237
    Np with a half-life of 2.14 million years, 236
    Np with a half-life of 154,000 years, and 235
    Np with a half-life of 396.1 days. All of the remaining radioactive isotopes have half-lives that are less than 4.5 days, and the majority of these have half-lives that are less than 50 minutes. This element also has 4 meta states, with the most stable being 236m
    Np (t½ 22.5 hours).

    The isotopes of neptunium range in atomic weight from 225.0339 u (225
    Np) to 244.068 u (244
    Np). The primary decay mode before the most stable isotope, 237
    Np, is electron capture (with a good deal of alpha emission), and the primary mode after is beta emission. The primary decay products before 237
    Np are isotopes of uranium and protactinium, and the primary products after are isotopes of plutonium.”

    and i think we might have found the missing plutonium! there, that was easy! i hope!

    from the link

    • arclight arclight

      first this
      “Neptunium was first produced by Edwin M. McMillian and Philip H. Abelson, working at the University of California, Berkeley, in 1940. They produced neptunium-239, an isotope of neptunium with a half-life of about 2.4 days, by bombarding uranium with slow moving neutrons.”

      And then this
      “Uranium-239 is an isotope of uranium. It is usually produced by exposing 238U to neutron radiation in a nuclear reactor. 239U has a half-life of about 23.45 minutes and decays into neptunium-239 through beta decay, with a total decay energy of about 1.29 Mev.[2]. The most common gamma decay at 74.660 kev accounts for the difference in the two major channels of beta emission energy, at 1.28 and 1.21 Mev.[3]

      239Np further decays to plutonium-239, in a second important step which ultimately produces fissile 239Pu (used in weapons and for nuclear power), from 238U in reactors.”

      Interesting bit that last paragraph maybe?

      And this interesting link with this quote

      “A full-controlled criticality of the element neptunium was achieved in late September 2002 at Los Alamos National Laboratory’s Technical Area 18 using a six kilogram nickel-clad neptunium sphere in combination with approximately 60 kilograms of enriched uranium. Scientists now know it takes about 30 percent less neptunium than previously thought, or about 60 kilograms, to generate a nuclear chain reaction.”

      wonder what sort of “experiments” they might have been up to at old fuku? Just trying to stimulate the grey matter a bit with this one!

    8/15/2011,Tepco confessed there is a huge pool on the basement floor of Fukushima,which is shared by unit1~4. They stock 6400 nuclear spent fuel rods in it,and groundwater is flowing into the pool.Now the massively contaminated water is at least 9.0t.
    6400 fuel rods is about 140% of the total fuel rods in the reactors.
    Actually Fukushima nuc plants are built on unde…rground water vein,they always needed to pomp up groundwater. However,because of the accident,they stopped pomp up the water.This fact has not been published yet.

    i then clicked on the cached version …loads of info here on plutonium and spent fuel etc…wonder why it was taken down? Heres a sample of the text…
    cached version
    “Furthermore, they’ll tell you that reprocessing is the ultimate danger and that if we dare recycling fuel, then others will recycle their fuel too (many already do, by the way) and if they do that then certainly they’ll be building weapons.

    Of course, there are plenty of countries that reprocess fuel to one degree or another and don’t have nuclear weapons. Germany, South Korea, Japan, Belgium and Italy either reprocess fuel or have done so in the past but never had a nuclear weapon. Countries like Russia, France and the UK reprocess civilian reactor fuel but have never used this fuel to build a nuclear weapon.”
    “However, there’s a problem that comes with the irradiation process: During the irradiation period, some of that plutonium-239 will also absorb a neutron. If that happens, it will usually fission, but up to a third of the time it won’t – instead it will become Pu-240. Likewise, some of that neptunium-239 will absorb a neutron before it gets a chance to decay to plutonium-239, thus resulting in neptunium-240, which quickly decays to plutonium-240. Because of these reactions, any reactor-generated plutonium will have some plutonium-240 in it.

    Plutonium-240 is what you do not want when you’re building a nuclear weapon. For one thing, it’s not fissile and for another, it’s highly radioactive (four times more so than Pu-239), but what really makes Pu-240 so problematic for weapons use is that it has a high rate of decay by spontaneous fission, which produces neutrons. The rate of spontaneous fission of Pu-240 is so high that even with a tiny bit in a sample of plutonium, it will have significant effects on critical mass. If plutonium were used in a gun-triggered weapon, the spontaneous fission rate would mean that the bomb would begin to fission before the two portions came fully together. This is pre-initiation, and it results in the weapon blowing itself apart before it actually gets a chance to achieve a full blown nuclear reaction. It’s commonly known as a fizzle.”
    “In face, 93% pu-239 is considered the low end of what is generally acceptable for weapons use and would work rather poorly in most weapons designs. Countries like the US, Russia, France and other advanced nuclear weapons states usually use even purer plutonium with concentrations of unwanted isotopes as low as 3% or less.”
    “Producing weapons grade plutonium would mean irradiation cycles as short as a month. This would mean the reactor would be shut down almost as much as it was running, dramatically compromising its power producing capabilities. The cumbersome procedure would be made even worse because of the fact that the fuel assemblies use long, cladding rods, not the easily processed slugs that weapons reactors use. A power reactor of this type might be able to handle a fuel system more favorable to such frequent reprocessing and re-fabrication, but only with very extensive modification.”
    The biggest revelation was the source of the plutonium: it was not American but was imported from the UK. If the US wanted to test how lower grade plutonium would preform in a weapon, why not just use plutonium recovered from one of the power reactors in the US? After all, by 1962, the US had a number of PWR’s, including Shippingport, Yankee Rowe, Vallecitos Nuclear Center as well as a number of prototype naval reactors in operation at the Idaho National Laboratory.
    “Thus, there were only three nuclear reactors in the UK that potentially could have provided plutonium in 1962. Calder Hall can be ruled out because it was known to be operating at full capacity in weapons production mode at the time. Thus, the material it produced would be considered “weapons grade.” Reports indicate that in its early years, Berkeley was also used for producing weapons grade material. To this day the British government remains secretive about its historical plutonium breeding capabilities, and the level to which Berkely was used to produce nuclear weapons material is not entirely clear.

    Had the material come from Chapplecross, it would have represented an abnormally long period of irradiation, since Chapplecross was primarily producing weapons material. Had it come from Berkeley, it would also have had to be low burnup, if only because of timing. Considering that it takes a good two to three months to cool, reprocess and fabricate fresh uranium rods into a weapons pit, that would have left only about three months for irradiation at Berkeley, even if the test took place in late December of 1962. Since the plant came online in July, there wouldn’t be enough time to heavily irradiate fuel rods. Also, at the time Magnox reactors ran exclusively on very low enrichment or unenriched fuel, limiting burnup, and because burnup directly effects fuel element integrity, early experiments with Magox reactors at higher burnup progressed conservatively, with usage extended in small intervals.”
    And the last paragraph
    “Some have said that this would be a deadly weapon as a “super dirty bomb” – the reality is that it would be a very big, bulky weapon that wouldn’t be much more powerful than its own weight in dynamite. It might spread around some plutonium, but the radio-toxicity of plutonium is not all that high and the spread of such material would be fairly local. Given that it’s primarily an alpha emitter, it would have to be inhaled or ingested to cause harm. If one went off, a couple blocks would need to be shut down while some guys in Tyvex suits washed everything down. We’ve actually experienced some weapons accidents that spread plutonium in a local area before. They weren’t the end of the world.”

      Japan goes the same way as Belarus: Dictatorship – a deep insight
      July 24, 2011 by Mikkai

      “The secret Agenda of Japan & IAEA is in full effect. Like in Belarus, where 72% of the Chernobyl fallout went down.

      Principal Sawai of Yumoto Daini Middle School, Iwaki City, Fukushima: “The radiation problem is already finished,” he told the children and their parents. “You can go to school and go outside without any problem. You should not fear malicious gossip.” SOURCE:

      1996 said the belarusian president Lukashenko during a meeting of the IAEA: “We encourage people to come back. We will open the shops again and enable the people to return to their evacuated towns and villages.”

  • sueec

    Asked this on another thread… could the aquifer that fukushima daiichi sits on be the reason for big readings of isotopes 40kms away?

    • arclight arclight

      have been giving your question some thought..its been a much discussed topic here!
      the aquifer under the plant i believe is a seawater aquifer..
      however cracking of the ground could have opened channels, but to where and how quickly does it move..
      the contamination area does seem well within the described “heavily” contaminated area done by the japanese researcher! and it seems to follow the direction of the wind as the various reactors exploded!

      back to your point on aquifer contamination…if the coriums have sunk into the mudstone and there was fissures and water it would make sense maybe that steam plumes could pop up out of the ground…surely something like this would have been reported as the steam would probaly be super radioactive! just some thoughts here!

      • Sickputer

        >could the aquifer that fukushima daiichi sits on be the reason for big readings of isotopes 40kms away?

        Probably not as groundwater contamination is glacier-like in movement through large aquifers and
        we’re talking upslope against gravity heading inland.

        Also it has not been established whether there even is a large significant underground aquifer in the Fukushima Daiichi area or even inland for several miles.

        But the sea water “vein” is quite possible from the initial plant construction (they probably used dynamite which fractured the mudstone) and the earthquake may have enlarged those fissures or cracked new channels to the sea.

        I doubt they can ever stop the migration of underground toxic water to the sea…ever. They would have to build a 200 Billion dollar dike and that is never going to happen.

      Critics skeptical of nuclear plant safety assurances
      “The U.S. Nuclear Regulatory Commission has twice rejected calls to expand the evacuation zone, add shelters and distribute iodide pills directly to residents, first in 2001 when it approved extending Turkey Point’s original 40-year operating license for 20 more years to 2033. Then, earlier this year, the Atomic Safety and Licensing Board, an NRC review panel, dismissed the concerns again.”

    • BreadAndButter BreadAndButter

      Florida Power & Light employees heard a “loud bang” Thursday (11th Aug. 2011) at the utility’s Turkey Point nuclear plant near Miami when a large valve carrying water unexpectedly closed, turning off a cooling system for one of the reactors, according to a Nuclear Regulatory Commission report on the incident. FPL employees followed their procedures, immediately opening one of two backup valves to fix the issue within 20 minutes, said FPL Spokesman Mike Waldron. “This situation did not impact our ability to operate safely,” he wrote in an email. “The noise was caused by the two-feet wide valve closing.” Federal regulators say they haven’t determined the safety significance of the incident yet but NRC Spokesman Joey Ledford said he doesn’t think it will be considered serious because they didn’t shut down the reactor, as nuclear operators often do to be on the safe side when problems arise. Ledford said the system cools important equipment and “it is a concern when the component cooling water system is not working,” Ledford said. “We are very closely observing the repair efforts and we’re looking into this in depth to see if there’s a need for regulatory action.”

    I have read a couple of new things today. Unfortunately I have no time to see if already discussed.

    1. Radioactive steam is coming up through the cracks in the ground at the Fukushima plant according to an email a worker has sent to his friends. This sounds like they (and hence we) may be in deeper shit than they and we can imagine.

    2. More than a 1,000 children in Fukushima were tested and more than 50% found to have radioactive iodine in thyroid. The town is 60kms from the plant is it not?

      Hi odylan 😉
      thanks for sharing. Relax if you can and go through some of the headlines.. 🙂

      • arclight arclight

        well that seems to be the smoking gun…so to speak!

        “I’ve heard that steam is coming up from the cracks in the ground.We are afraid of it.”

        Another Fukushima worker,
        “Near the reactors,there are a lot of the cracks in the ground,steam splashed out from there sometimes.and we have detected 10Sv/h at 6 places unlike gov’s announcement.”

        This has been known among our Japanese community,but we were not sure if it was really true. We did not want to go over the top.

        That’s there is a huge pool on the basement floor of Fukushima,which is shared by units 1~4. They stock 6400 nuclear spent fuel rods in it,and groundwater is flowing into the pool through broken duct.

        However,this evening,Tepco “confessed” a new fact.

        Now the massively contaminated water is in it at least 9.0t.

        6400 fuel rods is about 140% of the total fuel rods in the reactors.”

        steam coming from cracks in the ground?

        according to what i understand the corium has hit the basement and continued through 20 meters of concrete base, into the mudstone (which i believe has only been checked to about 150 meters by the initial survey team).

        somewhere there it has met water (seawater, cooling water or possibly fresh water)

        question? how far has the corium/s gone down?
        possibly quite deep as the iodine seems to be converted into its daughter product..

        how fierce is the reaction underground?
        for iodine to convert as it does in underground testing, maybe a large blob is currently intact and being very fierce indeed!

    sueec typed these pixels of light a little over 10 hours ago:

    >8/15/2011,Tepco confessed there is a huge pool on the basement floor of Fukushima,which is shared by unit1~4. They stock 6400 nuclear spent fuel rods in it,and groundwater is flowing into the pool.

    That sounds about right for March numbers of the CSFP (Common Spent Fuel Pond) which was 6291 fuel assemblies in November:

    It could have picked up a few more in storage from Noevmber to March to approach 6,400 fuel rod assemblies which is about 595,000 individual zirconium-clad nuclear rods by my math:

    See Tepco PowerPoint from November 2010:

    And also for more reading my long split post on the rod counts and fuel weight from June 6 Enenews:

    My calculations: 1.9 million fuel rods at Daiichi and weightwise…4 million pounds of fissile fuel.

    So the latest report is not necessarily “new” news except for the location of the pond. I don’t remember reading if there had ever been definite information about whether it was an elevated cooling pool in the CSFP building like Unit 4 or a basement. Weightwise it makes more sense to have that many rods in a ground or basement pool so that helps us understand what we are dealing with in that building. Kinda like a Ft. Calhoun on steroids to paraphase Arnie. *;-)

    In any event we know there is nearly 40 times the fuel of Chenobyl and the danger factor with MOX fuel makes that 40-1 factor look like a really lowball estimate if just weight is all we look at.

    With the plutonium factor Fukushima has to be considered hundreds of times more dangerous than Chernobyl.

    To again paraphrase Arnie: In fuel weight it is indeed Chernobyl on steroids, but with the MOX factor it becomes Chernobyl on HGH.

    The composition of the mudstone and even granite fissures beneath Fukushima would be a lot better known to Tepco if they had some of their Mitsunami folks doing test drilling.

    I have found more recent research in Mitsunami by geologists in Japan that invalidates some of the older research indicating the mudstone and granite layers under Fukushima are hard pressed through time and relatively inert and impervious to water..

    JAEA has been studying tomograms of central Japan since 2002 trying to find a safe location for high level waste. Unfortunately the fissures in granite are showing up in their research of the past 9 years and interconnectivity to other regions is certainly possible. Maybe not large flowing aquifers, but fractures in the granites have been discovered:

    Small excerpt of this 18 page PDF geological report revised in September 2008 and published in 2009:

    “The Mitsunami Underground Research Laboratory (MIU) is located in the central part of the main island (Honshu) of Japan. The site has been operated by the Japan Atomic Energy Agency (JAEA) since 2002. The adequate prediction of fluid flow and radionuclide transport in the subsurface is critical in the design of high-level nuclear waste repositories.”

    It’s heavy reading, but does leave no doubt that fissures exist even in the deep granite layers which was thought by the older Japanese scientists to be impermeable.

    This could be important if the corium is sinking through many meters of subsurface.

    Worst case scenario: The nuclear lava finds a substantial cross fissure of water providing a medium for massive hydrovolcanic nuclear explosions blowing the Daiichi complex into oblivion and as a side consequence destroying the other nuclear plant at Fukushima Daini 6 miles south of Daiichi:

    Nice map showing the two plants:

    That frightening scenario is certainly not pleasant to consider because the consequences for Japan and Korea would be beyond bleak indeed and grim for the rest of the world also.

    Been reading these comments since 3/11. But not much info. floating round about where the contaminated water they’ve been dumping into the ocean (since nearly the start of the accident) is traveling round the world. Some worries about migrating fish for sure but which fish and then which where will be affected most? Been living in brazil last year and a half and an oceanographer friend of mine gave me this link

    With these instructions you can build ocean current models with this software, GNOME, but have to know what they are dumping into the water. How heavy some of the radioisotopes are in order to gauge how and where they will travel in some of the well known currents. I keep wondering what this is going to do to our ocean, the ecosystem, and ultimately us. I keep wondering exactly what is in the junk they are dumping day and night for nearly 5 months now into the sea. Any ideas from the bigger minds on the site?
