Title: Regulators confirm level 1 incident at Kashiwazaki-Kariwa plant
Source: Kyodo
Date: Dec. 19, 2012

Japan’s nuclear regulatory authority said Wednesday that recently confirmed trouble with fuel rods stored in a spent nuclear fuel pool at Tokyo Electric Power Co.’s Kashiwazaki-Kariwa plant is a level 1 incident on a 7-point international scale.

A pair of fuel rods was touching as a result of deformation in the bundle of fuel rods, leading the Nuclear Regulation Authority to determine that the fuel had likely been loaded to the reactor core “in an abnormal situation.” The NRA’s assessment of the incident is provisional. [...]

    I'm sure TEPCO has things under 'complete control'. If they didn't, the 'liberal' media would be all over it warning people of the dangers. After all, what could go wrong with a couple of bent rods? It's not like proximity has anything to do with criticality right? Good thing this stuff is hard to understand or there might be reason for concern.
    At least it's on the west coast of Japan. That gives us here on the west coast of the US an extra day to cover our gardens. See, you just have to think positive and radiation won't affect you. Yippeeeeee

  • I wonder if this has anything to do with all these melting power plants:

    6,000-sq-km area sank following Tohoku earthquake, say scientists
    NATIONAL DEC. 19, 2012 – 07:05AM JST
    http://www.japantoday.com/category/national/view/6000-sq-km-area-sank-following-tohoku-earthquake-say-scientists

    "TOKYO —
    The Ministry of the Environment said Tuesday that an area more than twice the size of Tokyo subsided following last year’s Tohoku earthquake.

    The ministry announced that scientists have discovered the height of the land has changed in an area encompassing seven prefectures aside from the three worst-hit prefectures of Miyagi, Iwate and Fukushima, Fuji TV reported. The 10-prefecture area is 5,919.5 square kilometers in size. On average, the ministry says the land within that zone has sunk more than 2 centimeters as a result of the quake.

    According to the ministry, the worst-hit areas were Ichikawa in Chiba Prefecture, which is now 30.9 cm lower, and Tsukuba in Ibaraki, which sunk by 15.2 cm."

    At Fukushima, on the other hand, nearly every spent fuel assembly is deformed. Some have dumped fuel pellets into piles on the floor of the SFP. Some of these piles of pellets probably melted into puddles when the fuel pools were dry in the days following 311. Other fuel assemblies have become badly corroded, and will spill their fuel pellets as they are moved and handled during the planned fuel removal. Some fuel assemblies in SFP3 were damaged when neighboring fuel assemblies were launched during the explosion that demolished Unit3. Spent fuel assemblies at Fuku are probably all level 1 incidents. Emptying the spent fuel pools is going to be a demanding and time consuming process. There is certainly a gigantic mess to be cleaned up. It will not go smoothly. I saw a radiation map the other day that showed a large rectangle around Fukushima still running above 400cpm. What can it be like for the workers? Tyvek suits can't be much protection.

    What are the odds for building 4 considering subsidence and tremors?

      it's not a matter of odds, it's a matter of calendar.

      Not if but when.

      All these units are seriously damaged and when they cooled them with sea water, they started
      eroding all the pipes, valves, regulators and pumps.

      if the system holds together for another year or two, they can maybe see the local field radiation drop enough to get in and repair things, but, what they need to do is strip the fuel pools and see if they
      can deal with the corium in units 1-3.

      instead they are screwing around.

      send 10,000 men to die now to avoid a disaster that kills millions.

        I think that many of us feel the same as what you have stated here.
        Yes, 10,000 men is certainly needed to show bushido here. The legions of workers gave it their all at Chernobyl. My greatest concern is for the future's children everywhere.

          +1000 for every post found in this thread!~I wonder how long it will take & how the Japanese will feel when more "gaijan" volunteers than their own people HAVE to step up and fill the ranks of those 10,000 because they haven't??!! I guess since getting nuked and losing WWII they're balls have shrunken in comparison to their ancestors?! I'd go if my wife loses her battle with cancer and I'd do the best I could but not for the sole purpose of being a part of the crew who try's to save the world. My secondary & more selfish motivation would be to do what I can to help for "my" people and for the chance that I might get to punch someone responsible for the mess or who orders children to eat food holding a 99.9% chance of being tainted in their face! It(might) be worth the incarceration and/or "death sentence" pretty much guaranteed for those who've been close enough to the festering pimple squirting radioactive pus from the a-hole of Japan to see it in person! We should "oxycute" all of the idiots in industry,govt.,and so-called "environmental public health agencies"(not just in Japan either!) I've already worn out my favorite suggestion to "put some Preparation H in the nuke pukes shoes and they'd disappear"! I personally favor the idea of "force feeding" TEPCOcrats their own product line that they've so generously given to everyone on the planet for nearly 2 years & running!.. :(

        TEPCO needs to deal with this GLOBAL situation as if it were a global problem. The human race must begin to think BIG about Fuku. Empty SFPs this year and next.
        Think in terms of a modified Mobile Marine Crane, that can move from Building4 to 3, 2, and 1 to empty SFPs.
        http://www.marinelink.com/news/travelifts-completes335890.aspx
        Prep each building by removing structure to equipment floor level. Then move the Mobil Crane from building to building. Since it is metal, it can be built fast. Work should proceed day and night.

        Map the corium, using existing satellite and oil industry technology. If the oil industry can find a pool of oil 8,000' underground, they can find the corium in the mudrock below Fuku.

        Build a Closed Loop Cooling System to cool the corium. Build a cofferdam around the site, use injection wells, build cooling towers or enclose the lagoon within the cofferdam. But do something to contain the radiation while cooling the corium.

        Building a foundation for the sarcophagus. Completely around Buildings1,2,3,&4. Deeper than the corium. Pound in two steel cofferdams, 100' apart. Dig out rock between cofferdams for concrete.
        http://www.sodahead.com/fun/does-size-really-matter/question-1990001/

        If coriums are unstable, use a mobile oil drilling rig to drill down, then horizontally under the corium. Create a manifold to circulate coolant to chill the corium.

    What we need is international cooperation to deal with a threat against all of us, Jonny. (What we don't need is to threaten violence against Japanese criminal nuclearcrats.)

    To continue:

    Have the crews that are building the new cover for Chernobyl come to Japan to build a Cover for Buildings 1,2,3,&4. With a similar cover.
    http://www.world-nuclear-news.org/WR-New_Chernobyl_cover_takes_shape-2911124.html

    Fill Reactors and Containments1,2,3,&4 with a mixture of sand, boron, and other ingredients fireman Markww has told TEPCO to use. Use same mixture to cover puddles of melted fuel, and spilled fuel pellets in SFP1,2,3,&4.
    Fill Buildings1,2,3,&4 with concrete.

    Cover ground between Buildings1,2,3,&4 with reinforced concrete to a depth of 4', all the way to the cofferdam and concrete foundation for the sarcophagus. Install a membrane roof over the concrete.

    Power the Closed Loop Cooling System with wave or tide power, so that the coriums can be cooled indefinitely without human intervention. Measure constantly for any leaks. Japan, if you can't handle this project, then get out of the way, and let somebody else do it.

      PhilipUpNorth – "What we need is international cooperation to deal with a threat against all of us,.." Absolutely! IMHO – the UN is the existing body out of which this *should* emerge. It's got the 'infrastructure' in place to pull resources together. It's what the UN should *always* have "been about".

      But IMO, until it is 'occupied' by 'servants of the people', whose first priority is earth/life care at global levels, (vs power/prestige wealth accumulators), we'll have sections, like IAEA, functioning as we usually see.

      So – wonder how we can tackle the IAEA's practices as a citizen's movement? (In our spare time, of course)! Global citizen's email, phone call, and/or petition blitz?

        The revolution is already in process, Maggie. It's called the Internet, where the ideas of the many percolate, until, hopefully, the best ideas float to the top and are acted on. You are right. The IAEA, and all nuke industry advocacy must be driven out of the UN, and also out of the DOE/NRC of the US Government. Nuke power is so uneconomical and the risks are so large, that all of Earth's nukes will be decommissioned in the next 50 years. This is a fast change, in terms of our cultural history. Change seems agonisingly slow to those alive today, but each change reaches a tipping point, and a new organizational metaphor emerges, one of respect for Mother Earth and concern for her protection. This will replace the current capitalist organizational metaphor, with greed, concentration of wealth, economics of scarcity, and corruption of government, which is being laid bare, and which is dying right before our eyes. Hope you are having a most enjoyable revolution, Maggie! :)

          PhillupUN – When reminded how well the revolution is underway – hard not to enjoy!

          Awareness: uncountable pockets of misery and all-consuming challenge at personal and biological life level along the way.

          re: "This is a fast change, in terms of our cultural history" — ideas and cultural memes like cells multiplying and for the most part thriving, exponential. "The fractal universe".

          re: "… a new organizational metaphor emerges, one of respect for Mother Earth and concern for her protection. This will replace the current capitalist organizational metaphor.." — Seems it cannot be otherwise, but astonishing staying power of the 'dying throes' none-the-less!

          Thanks. :)

    Perspective: While the nukecrats in the Japanese Diet debate whether to restart the nation's nukes, their children take part in the demonstrations to end nucler power for all time. This is why nuke power will die. Women are having abortions, rather then risk giving birth to deformed babies. Parents are told not to send lunches to school, and try to force children to eat contaminated lunches made from meat and produce from Fukushima. The people know what the nuke industry is doing to them. And the people are saying "No thank you!" in a big way. Cheers, Maggie. :)
