Asahi Shimbun, May 23, 2015 (emphasis added): Risk of hydrogen explosion from leaking containers at Fukushima plant… at least 10 percent have leaks, which could trigger a hydrogen explosion. [TEPCO] reported its findings at a meeting with a study group from the Nuclear Regulation Authority on May 22… there were about 1,300 such containers at the plant… The first leak was discovered in a lid on April 2… Of the 278 it had examined by May 20, it found 26 had some sort of leak or were bleeding from their lids… likely caused by hydrogen and other types of gases that resulted from the water’s exposure to high levels of radiation. Such gases appear to have accumulated in sediment at the bottom of the containers, expanding the volume of the liquid. An NRA official said the accumulating hydrogen poses a potential danger…

Unnamed Gov’t Official: “If the concentration level is high, a spark caused by static electricity could cause a container to explode.”

Mainichi, May 23, 2015: Container for Fukushima waste found without gas venting holes… [NRA officials] had asked TEPCO to create the holes. In early April, containers were found to be leaking radioactive waste liquids through the venting holes. Later in the month… it discovered the container without the venting holes. Out of the approximately 1,400 containers, 334… have not yet been checked for venting holes. TEPCO has speculated that the work to create the holes was skipped over at a factory in the United States.

NHK, May 22, 2015: Radioactive wastewater leak linked to hydrogen – The operator of the Fukushima Daiichi nuclear plant says recent leaks of highly radioactive wastewater from their containers were likely due to accumulated hydrogen gas in the tanks… TEPCO has found since April that the wastewater, produced during the process of treating radioactive water, had seeped out through the lids of a number of containers. The utility says that 26 of the 278 inspected containers had leaked, and in 15 of them, bubbles formed when workers stirred the liquid inside, and water levels went down. The utility believes the bubbles mainly consist of hydrogen, generated by strong radiation inside the containers.  TEPCO officials suspect the gas increased the volume of the wastewater, forcing some to overflow.

    Idaho’s big battle over a small amount of spent nuclear fuel via Nuclear Street

    … The result is that former Governor Batt, a republican, and former Governor Cecil Andrus, a democrat, have teamed up to oppose DOE’s plan to bring the two shipments of civilian spent fuel to Idaho.

    They see it as a camel’s nose under the tent, a first step in making the remote R&D site, located 50 miles west of Idaho Falls, ID, an interim storage facility for all of the nation’s spent fuel.

    Were that to happen it would likely be in operation for at least 100 years or longer taking in as much as 100 million tonnes of spent nuclear fuel. …

    The non-scientific poll was meant to gauge reader sentiment and encourage debate. An IP address analysis, however, showed that one-fourth or more of the 7,500-plus responses came from one location: Entergy Corp, 700 S. Louisiana St., Little Rock, Arkansas. …

    Fukushima-induced Polonium-210? Iodine-131, Cobalt-60, Cesium-134 & Neobium-95 detected in Europe (May 2015!)

    New blog post (May 25): Bunch of stuff mixed with self-distractions, but the gist is:
    - wondering if Polonium-210 is also being created artificially, and that Cobalt-60 releases could be astronomical. And that there ought to be testing for these, as well as for (stable) Lead-206… Maybe unusual lead concentrations in some parts of the Pacific are part of the die-offs puzzle? And then some…

    "More cell phones in India than toilets"

    Part of popularity of these solar lights is they can charge cell phones .. so obvious health benefits to folks without using the kerosene burners which cause a lot of respiratory illness among the desperate poor segments of the "slave" caste.

    But again .. not sure how you can lump the overall temperature changes just to nuclear.

    I would also suggest that most of the world now has more cell phones than toilets

    Maybe what's in those tanks is the dead bodies from all the workers.
    Almost added lol but the idea of potential bodies is nauseating. I can't see how water that left a leaky containment could be recovered and put in a tank.

      I really like your suspicious nature. I have asked why, although water continues to pour through the facility, do you "store" some of it? Are these tanks really there? Anyone can alter pics. Are they just a propaganda prop?

      Also, pics from world nuclear news show FNPP as a devastated melted mangled mess. Images I now see appear to be someplace else, altered. I can't link, but look on wnn, see if their still there.

        • Haha yes, plus….altering pictures really doesn't put money in anyone's pockets. Or job contracts on the the table….or bids to be won. Trust me oh people who think their big priority would be on a frenzy of picture altering to fool our little spying eyes. Tons of physical shit has happened. Mega tons, big fat tons of tons. :)

          Millions of nuclear related industries, each with purchasing contracting agents have been busy for 4 years putting together long detailed business deals for each tank, bolt, radiation suit, crane, light bulb, transportation vehicle, bucket, license, truss… whatEVER the needs… workers hired or anything that keeps those supplies and installations happening is a very real situation they will stretch out to the bitter end. :)

          Thus holes get dug, storage and reactor tents go up, equipment is brought from here to there…billions of real items procured that keep the money wheels rolling. And that sadly, has nothing to do with a different question, which is, have they actually made the mess safer? I doubt it. It just looks "sort of managed and prettier to inspectors and the general media reading public…in a superficial busywork, see what we did sort of way". The real altering and hiding is much more sinister.

          Yup, Daiichi…money manna from heaven to millions of involved makers, suppliers, tinkerers, etc.

    Editorial: Comprehensive evacuation plans needed ahead of nuke reactor restarts

    Shikoku Electric Power Co.'s Ikata Nuclear Power Plant stands at the base of the Sadamisaki Peninsula, a thin finger of land pointing southwest from the island of Shikoku toward Kyushu.

    Though the plant recently passed Nuclear Regulation Authority (NRA) safety inspections, opening the way for reactor restarts, its very location is a serious cause for worry.

    Namely, everyone living to the west of the plant on the Sadamisaki Peninsula could find themselves without an overland escape route should there be a nuclear accident at Ikata. …

    The nuclear accident response plans drawn up by Ikata plant host Ehime Prefecture and seven nearby municipalities fell outside the scope of the NRA's inspections, and it would be difficult to say they could cope with the kind of multi-disaster scenario seen on 3.11. If the process to bring the Ikata reactors back online goes ahead, it could threaten the safety of the people living close by.

    Shikoku Electric submitted an application to the NRA for safety inspections of the Ikata plant's No. 3 reactor in July 2013 — the same month that new NRA safety standards went into force. The focus of the inspections was the relative likelihood of an earthquake.

    The Median Tectonic Line, one of Japan's major active fault zones, …

      runs roughly parallel to the Sadamisaki Peninsula, in waters about 8 kilometers from the Ikata plant. There are also fears that Shikoku could be hit very hard by a major Nankai Trough quake.

      At first, Shikoku Electric based its disaster preparedness plan for a hypothetical quake on a 54-kilometer stretch of the Median Tectonic Line in the waters off the nuclear station, but the NRA told the utility to rejig its calculations with a greater emphasis on safety.

      Shikoku Electric complied, modeling shifts in 480 kilometers of interconnected faults stretching all the way to Kyushu. The estimated shaking from a quake was also revised up from 570 gal (a unit of acceleration) to 650 gal, while the maximum height of a hypothetical tsunami was boosted from about 4 meters to 8.12 meters. The No. 3 reactor passed the NRA inspection under these more stringent conditions.

      Some 5,000 people live between the Ikata nuclear plant and the westernmost tip of the Sadamisaki Peninsula.

      Under Ehime Prefectural and other local government contingency planning, if there was a nuclear accident at the plant, every one of those 5,000 people would be directed to evacuate east past the plant, theoretically before any radioactive substances had escaped. That is, if the accident got very bad very fast and radioactive materials escaped before the evacuation, the residents would see their eastern escape route cut, and would have to be rescued by sea or air.

      If, however, it was …

        a major earthquake that caused this accident, tsunami damage could prevent any evacuation by sea. If we added bad weather to this scenario, escape by plane and helicopter would also become problematic. Concerned residents have apparently been voicing their worries to the Ikata Town Hall.

        It is the responsibility of local governments to set evacuation plans in case of a nuclear accident. The central government, meanwhile, has pledged to "give full support" to these plans.

        Prime Minister Shinzo Abe has said many times that he will green-light the restarts of reactors that pass NRA safety inspections.

        That being the case, creating evacuation plans that really do guarantee the safety of local residents should ultimately be the central government's responsibility.

        However, if this responsibility is left in the hands of local governments, we cannot support moving ahead with reactor restarts.

    Nuclear testing victims dubious about commission
    25 May 2015

    The head of an organisation representing victims of nuclear testing in French Polynesia says a commission set up to assess the aftermath of the testing could just be a charade.

    It was set up by France's defence minister, and will be made up of 24 members and chaired by the French High Commissioner in Papeete.

    The director of Moruroa e Tatou, which represents victims of testing on the atolls of Mururoa and Fangataufa, says 80-percent of the members suffer serious health conditions, including cancer.
    Roland Oldham is questioning why more more evidence is needed.

    "Why more more and more commissions…isn't there enough proof now that it had a bad impact on the environment, and a bad impact on the health of polynesian people – itsn't it enough proof?"
    He says they will make themselves heard.

    "As far as we're concerned, we will be speaking with a very loud voice, because we have had enough of all these lies, of 40 years of lying, and if this commission's just for another lie, then it's just a waste of money and a waste of time."

    Mr Oldham says the first meeting will be held in two days.

    Tepco blaming U.S. manufacturing is an ominous sign. Finger pointing by these war criminals means the whole sham is unraveling. Pretty soon they all will be scrambling to cover their backsides.

    This collection of official liars is impressive. The United Nations, the World Health Orginization, the N.R.C. The I.A.E.A. The E.P.A. and all the way up to the White House. Watching them turn on one another as the biosphere colapses will be some small consolation. ..

    The vast water tank farm at what used to be one of the world's largest nuclear electrical generating stations is insanity.

    All of the water will flow to the sea eventually after the tanks themselves rust into a cascade of collapsing cobalt-60 infused steel rubble.

    The awol reactor cores will forever be beyond containment, any thoughts of scooping up the remaining blobs and bits of the corium are for a future we will never have.
