Mid -and -Long -Term Roadmap towards the Decommissioning of TEPCO’s Fukushima Daiichi Nuclear Power Station Units 1-4 (pg. 115), June 27, 2013: Development of technologies for controlling fuel debris criticality –> Purpose: In future, we will develop the technologies for monitoring and evaluation of sub-criticality in order to prevent re-criticality even in the case when the form of the fuel debris or the water volume changes in association with the fuel removal work etc. […] Criticality evaluation […] Conduct an analysis assuming the status of fuel debris and the plant after a severe accident, and review the scenario involving a criticality. […] formulate measures to mitigate the influence of radiation exposure in the case of a criticality. […] Liquid waste treatment and subcriticality control technology for cooling equipment […] Considering the possibility that fuel debris may flow out, accumulate in the liquid waste treatment equipment as well as the cooling equipment and lead to criticality, monitoring of subcriticality is required.  […] Mid- to long-term cultivation of human resources […] we will need more persons with expertise on basic nuclear core physics and criticality control, we will consider cooperative frameworks which will promote education and research in universities. Further, we will make efforts toward the development of the ability of young engineers, and secure the human resources required for ensured implementation and improvement of long-term debris criticality control.

Q&A with Lake Barrett, former U.S. Nuclear Regulatory Commission official and now an adviser to Tepco, March 30, 2011 (at 1:08:00 in): Mike [Podolsky?]: A few days ago I received an update from Japan talking about the measurements. The temperature outside the vessel was almost 300*C. The pressure inside the vessel was about 3 atmospheres. Which means that the temperature inside was much higher. The coolability of molten corium is questionable […] We should make a really organized effort to understand and look into long-term consequences, because it’s not clear that everything will go away in a smooth manner.

      This actually is one of the more, or one of the most important news items on enenews. If they can't cool the corium, then it will reach criticality again and explode. I wish that commentators who don't understand the science would take their jokes to the off-topic section of the forum. Of course, if those commentators are really pro-nuclear and want to divert the subject matter and make this website look unscientific, then they are doing a good job.

      I am referring to the comments below. This situation is very sad and we don't need such silly jokes. We need scientists focused on solutions. It is a waste of time for scientists or people trying to become informed to have to read through off-topic jokes.

    "…look into long-term consequences, because it’s not clear that everything will go away in a smooth manner."

    Plain as day…the definitive avoidance of reality, thinking that
    any of this could "go away".

    By default it is a language of deception, though most people
    are not aware of the fact.

    "…we will make efforts toward the development of the ability of young engineers, and secure the human resources required for ensured implementation and improvement of long-term debris criticality control."
    Like Nixon offering "An honorable end to the VietNam war".
    Few people remembered the "honorable" part, which was the expectation.
    The actual quote is as ill defined as possible, by design.

    "We will make efforts"??????

    "Published on Nov 4, 2013

    Worried Chinese shoppers stripped stores of salt in cities across China on Thursday in the false belief it can guard against radiation exposure even though any fallout from a crippled Japanese nuclear power plant is very unlikely to reach China.
    The panic shopping was triggered by rumors that iodised salt can help ward off radiation poisoning part of the swirl of misinformation crisscrossing the region in the wake of Japan s nuclear emergency.
    People are buying the salt for three reasons many think the iodized salt will protect them from radiation others think that radiological contamination of the ocean will polluted salt supplies and many think the price of salt will go up and are buying it on speculation.
    Already some are selling bags of salt for five times the price it was a day or two ago. Supermarkets and groceries in many cities across the country have run out of salt in the last few days as a wave of panic buying spread across provinces from eastern Zhejiang province to southern Guangdong to western Sichuan. The rumours have flown widely. Text messages on mobile phones have circulated about nuclear plumes spreading from Japan throughout Asia."

    Okay, so, I've been reading and learning here since the first week and have yet to comment because, well, I'm a scaredy cat. But I can't take it anymore. Been hoping somebody saw what I saw. It has always been my belief that the elusive corium or coria (from one or several reactors) melted down after the earthquake and was spread far and wide by the tsunami. I watched on live television as the wall of water pushed inland and, many times, everything the water touched burst into flames on contact. I assumed at the time that the flames were from downed power lines or gas explosions in the homes. In hindsight, and knowing what I know now, could the coria have been carried by the water and spread onto land with some of it deposited, and some carried back out to sea? The flames seemed so instantaneous when the water hit any flammable structure that it didn't make sense to me at the time. I was just fascinated that things were incinerated on contact. I have video somewhere and will search for that, but I figured one of you many marvelous people may come up with it more quickly than I. Just food for thought from a dedicated follower of ENENews.

    Many of you feel like friends to me, albeit it's been one-sided. Sorry to have lurked so long and for withholding this potentially helpful theory.

    Glad to be among you.

      Speak up. Welcome!

    • Dr. Anne Lee Tomlinson Maziar anne

      It is my understanding that the earthquake broke the cooling pipes. Then there was the tsunami ( sort of remember 45 minutes later). But the fuel takes a while to heat up. So it wasn
      t until the next day before the first explosion. So the coria wouldn't wash out with the tsunami. You can get a time line on wikipedia. I will look it up.

        http://en.wikipedia.org/wiki/Timeline_of_the_Fukushima_I_nuclear_accidents

        I don't think you can wash away a corium under any circumstances. Because the corium is so hot it does travel down through the earth, and because of the lack of bedrock beneath Fukushima and because it is so close to the ocean and was built with the basements even below sea level, it is believed by many to have already reached the ocean and is emitting radiation. But I don't think it is being broken up by the ocean.

        There are other on this site more knowledgeable than I am. I am just commenting to attract the attention of other to your question.

        • Scaredy Cat Scaredy Cat

          Thanks Anne. I respect your opinions very much.

          I wonder what made homes and debris burst into flames on contact, with water? I just Googled "tsunami flaming water" and there are pics and videos of the phenomenon to which I am referring. It was mighty weird watching it happen. Could it be fuel that was ejected skyward, or were the explosions too long after? I will check the timelines.

              There are lots of things I don't know. I just search on the internet for explanations of others.

              “One thing to realize is that a normal gas line filled with natural gas is above the upper explosive limit, because not enough oxygen is present to support combustion. When the line is cut or damaged, however, oxygen can be introduced from the surrounding air, which can contribute to a fire or explosion.

              “If the house was serviced by gas and the furnace was on, then gas was already flowing into the house. However, instead of having pure natural gas carefully combined with air in the furnace, you might instead get an explosive mixture coming into the house which, as soon as it contacts a spark or heat source, explodes–possibly even inside the gas supply line.”

              Some solvents will spontaneously combust when exposed to air. Many other things will, too.

      @Scaredy Cat:
      Welcome aboard!

      As a design engineer (30+ years now) I can say with confidence
      that there were no coriums in the buildings during the tsunami.
      Hot (temp) fuel rods?
      Certainly.

      Coriums forming were days later, roughly.

      The tsunami happened about 60 min after the quake.
      Before the tsunami, things were already quite FUBAR.

      The major effect of the tsunami was to knock out the back up generators.

      I will offer the argument that the back up systems were a moot point after the actual quake since so much to the cooling systems plumbing were ripped up/out so quickly anyway. Huge pipes were ripped out of the walls and flanges were thrashed beyond repair. The cooling system damage would have required many days if not weeks/months to fix even if the melt downs never happened.

      Strange how the media keeps blaming the NPP failures on the tsunami, when it was the quake that did the damage they had little hope of recovering from.

      Recall that TEPCO is a NPP operator.
      Like a bus driver.
      They are not trained/prepared on how to fix anything that is seriously broken.

      I have personally known guys who have been part of building and operating NPPs. There stories are best summed up as Beavis and Butthead team up with the Three Stooges to come fix your clogged toilet. No they won't get it fixed, and yes, the problem will be much worse after they leave than before they arrived.
      And you will still be billed for their expertise.

    Lake Barret: One of the more accomplished nuclear apologist. When the news focuses on the negatives of nuclear power then the media is bad. When the media reports the nuclear industry talking points then the media is good. The standard, take a bad situation and make it positive. I,Cs,Sr releases only cause collateral damage and can be overlooked as political.

    Barret (a dinosaur) is also throwing in the towel now. Wanted containment and a closed loop cooling back since day one of the accident along with tenting to filter off gassing, 2 1/2+ years later, he has none of that. Have to do what you have to do to keep the nuclear industry viable and on point, Pacific as a dumping ground will be the name of the game. The melts are lost and he has no answer for it.

    Asking to recruit fresh minds for old, reoccurring and unresolvable problems is a waste of resources, draining away from other needed projects like flexible electrical grids, renewable energies, etc.

  • jcfougere jcfougere

    I know this has been answered and is somewhere on the site, but could someone please tell me the estimated time it would take an atmospheric release (SFP4 Collapse etc) to reach the West coast of North America? How long we have to evacuate should the worst happen?

    • Speedy

      Not long, I believe the balloon bombs they sent over were here in 5 days….

    • fireguyjeff fireguyjeff

      jcfougere:
      Japan is about 4850 miles from Portland.
      So even at 50mph, it will take 4 days to get here.
      The critical variable here is how high up the fallout goes in terms of catching the winds (assumption..tropospheric).
      The higher up it gets, the faster, yet I would not expect an SFP release to get very high up, i.e. 10s of miles up.
      So a week is a good estimate. But certainly not months.

      Not sure what NatGeo was assuming…their estimate seems a bit short to me from a practical point…60 hours means 80mph!

      Bottom line is that we have already been hammered badly here on the west coast US.

      My take is that you would be on your own in terms of interpreting what you find here vs MSM for making a decision.

      By the time that Ken and Barbie get any clue that it might be a good idea to go southern hemisphere, things will have already shut down in terms of travel.

      Unless of course one was deemed "valuable" to a foreign country (very educated/useful/smart), and you could speak the language, and have money, etc.

      Note also that Fuku has proven that the air currents between hemispheres are not nearly as isolated as had been assumed in the past, hence, just a matter of time before there is no where to go.

      I highly recommend you watch both versions (1959 and 2000) of "On The Beach" to get calibrated on the idea of an escape plan, if it can be called such.

      • jcfougere jcfougere

        Thanks for that Fireguyjeff, I definitely won't be taking my news from MSM.

        It's very disheartening to know that if SHTF more than it already has, the entire globe will be covered in this stuff..

        Another reason I'm going to move South is that I feel like it's a better place to weather the peak oil storm, financial crash, all the other things that are headed our way in the near future. There also aren't any local nuke plants down there, but I guess that's not much of an advantage anymore :/

    • HoTaters HoTaters

      Some of the air in the upper air currents can reach the West Coast of North America in 24-36 hours. We've noted it takes 3-5 days for plumes from Fukushima to reach here after an event such as earthquake, fire at the plant, etc. That is based on readings from NETC. Kassandra and some others (myself included) have made a lot of posts re: that.

      Will try to post the link stating the air can reach here in 24-36 hours. Am thinking maybe Anne posted that one. Not sure. It could have been someone else.

      There was discussion of this subject in the past week, after Tepco removed fuel assemblies from SFP #4.

      • fireguyjeff fireguyjeff

        Ho Taters:
        Well, maybe we are splitting hairs here.
        A day and a half vs a week is all about the same when we are dealing with something this important in terms of "the big picture".

        I would be the last to argue that Fuku spewage couldn't get to the west coast in 36 hours….it just seems so quick considering the distance.

        I watch storm fronts here all the time and it can take days for them to move just a few hundred mile vs 1000s.

        My thoughts were that there would need to be a mechanism/process for getting the Fuku crap up high enough to get the faster winds.
        Without major explosions, I struggle to explain a fast trip of a day or two.

        Chernobyl fallout took about 4 days to get to the NE US.

        Studies done (9 months + 4 days) {+/- a few weeks window} on birth defects in Boston, NYC, Montreal and Toronto came in very close to each other.

        Bottom line was that birth defects essentially doubled for all 4 cities.

    I wonder how much Japan plans on spending to put on the 2020 Olympics. Do you think that money could be spent in better ways?

        If you check the Olympics web site..it's on..If that is true, Japan will be starting to build arenas, housing, outside sports complexes, etc..that all takes planing and time..My point was they should not start anything, they should pull their name and make it known they are investing those funds into attempting to fix the mess.

Times change and young men do not want to.cling to a repressive past idea. The older man who cannot change wants these young men to throw themselves into a pit.

    In the end, the machine malfunctions and kills the obsessed character. Old nuclear engineers have confided in me that they could not shift gears and go to medical school.for example because they have families to support. Plus, their obsession with an archaic idea limits their mental flexibility. Obsolete dangerous technology should be abandoned, not foisted on younger, more enlightened men and women.. (Men are more likely to become obsessed with nuclear energy and weapons but that is another matter).

    If society does not move on, it won't.

      My friend-good analogy and reflections. As you suggest, society should move on.

      There are many linkages between this notion and the idea that discipline is not to stop the mind in just one place. Based on your prior writings, you know there is no place to put the mind.

      As the Takuan Soho eloquently states, “when the mind is biased in one place, and lacking in another it is called “one sided mind.”
      We all have these and similar biases.

      Unfortunately the bias of many, including all nuclear engineers and their supporting corporations, is to assume that nuclear power and its effects are benign and perhaps inconsequential.

      We know this is far from the deadly reality. Peace.

    Some humans seem to think that Fukushima is not a problem for the simple reason that their simple minds cannot even begin to grasp what has happened or will happen, or for that matter what IS happening at the site.

    We are lulled by a sense of normalcy when we talk about the Tokyo 2020 Olympics.

    Japan does not, not for one minute want the rest of the planet to know the truth.

    We must go shopping!

    Now that we've had an accident we said was impossible, let's think about developing technologies we can use. And just in case there is another accident. But the odds of that happening again are almost infintesmaly small. (sarc)

    If the corium is in contact with the water underground, there is little anyone can do except to divert the water coming in from the mountains….and that is an extremely difficult problem to crack.
