  • fission is not a reaction ....
    by Edano 11/3/2011 7:29:34 PM

  • @lillymunster Well, see, this is a good example of loss in translation. I think what they mean, but are not clear enough about it, is that they found a bit too much xenon isotopes than expected. It is undeniable that fission will still occur, that's the nature of heavy radioactive isotopes. They added boric-acid solution to slow it down to what they consider safe limits. It's the media that has been making all the wrong assumptions. There is no indication of panic nor surprise in that report. So Tepco never mentioned nuclear chain reaction nor criticality in the first place, did they?

  • @Edano Fission can occur by natural decay or through a self-sustainable nuclear chain reaction. The first is natural and unavoidable, the latter can be disastrous. There should be no confusion about this.
    by Pedro Jesus 11/3/2011 7:33:06 PM

  • @Pedro Jesus you cannot slow down fission by boronic acid. this is only useful to stop a chain reaction.
    by Edano 11/3/2011 7:33:50 PM

  • "On Wednesday, Junichi Matsumoto, a Tokyo Electric spokesman, acknowledged episodes of fission, saying at a news conference: “There is a possibility that certain conditions came together temporarily that were conducive to re-criticality,” and that the measurements indicated a burst that occurred at a slightly higher rate than prior cases." www.nytimes.com
    by Edano 11/3/2011 7:36:09 PM

  • @Edano It does slow down the fission process by absorbing neutrons that could otherwise feed a chain reaction under certain circumstances. It does not change the natural decay (half-life) of the isotopes, if that's what you mean.
    by Pedro Jesus 11/3/2011 7:36:47 PM

  • @Edano That article at NYT is self-explainable. The operator's spokesman mentions that certain conditions that could lead to a re-criticality were observed, not that a re-criticality had happened or was even likely to happen. It is a pretty bad choice of words, if that's exactly what he said. I wonder if he spoke in English or in Japanese.
    by Pedro Jesus 11/3/2011 7:39:57 PM

  • sorry, I meant self-explanatory
    by Pedro Jesus 11/3/2011 7:40:15 PM

  • Another media article referring, maybe wrongly, to re-criticality: ""It can be assumed that isolated criticality took place for a short period of time judging from the presence of xenon," Tepco spokesman Junichi Matsumoto said."

  • Funny how such a short statement made in Japanese in a press conference can have so many different translations...
    by Pedro Jesus 11/3/2011 7:55:22 PM

  • @Pedro Jesus they need some sort of terminology agreement with cheat sheet. I saw the same thing only worse in the US when they had the ammonia leak at San Onofre. Every media outlet was calling it a different emergency classification. None of them seemed to have a clue what they were talking about.
    by lillymunster 11/3/2011 7:57:20 PM

  • the same confusion happens always with the words "containment" and "vessel". we are never sure what they mean.
    by Edano 11/3/2011 7:59:36 PM

  • @lillymunster Have you checked the comment on Youtube on that NHK article posted a few minutes ago? They clearly state that Tepco never said criticality had happened. What Tepco mentioned is that criticality would result in higher levels of xenon than the ones detected. Bad translations and quick assumptions, that's all.
    by Pedro Jesus 11/3/2011 7:59:42 PM

  • @Pedro Jesus that is their different story today, they have clearly changed their story over time on this.

  • @amber m Hi Amber, could you be a bit more specific? We could probably point you to some sources with some additional details.
    by lillymunster 11/3/2011 9:07:04 PM

  • We consider that they were generated by the
    spontaneous fission on the grounds that the concentration of detected
    short-half-like radionuclide (Xe-135) is low, that short-half-like
    radionuclide (Xe-135) was detected even after the boric acid, which stops
    nuclear fission chain reactions, was injected, and that the parameters of
    the reactor were not significantly changed.

  • @amber m Here's a bit originally from a Fairewinds Associates video. Fairewinds is a nuke consulting firm run by Arne Gundersen, nuke engineer and consultant at Three Mile Island accident in the USA. Transcript Excerpt

    “Two of the three monitoring stations in the United States did show hot particles in the air in April. Since then, there have not been any hot particles. But in April, it is clear that, at the worst of the accident, hot particles were wafted across the Pacific and deposited in Seattle and in Boston at least. There is also data that indicates contamination on the ground in the Cascades, which are a mountain range right up against the Pacific Ocean.

    So I think we have two problems here. In Japan, there is a personal health issue and what that means is that individuals have received enough radiation that there is going to be a statistically meaningful increase in cancers in Tokyo and especially in Fukushima Prefecture.

    In the United States, it is a different story. It is a public health issue and not a personal health issue. What that means is that we will never know who is the individual who got cancer from Fukushima. But we can be sure that the radiation did reach here and that there will be an increase in cancers, especially on the West Coast where the Rocky Mountains stopped most of the radiation and deposited it on the ground.” Fairewinds video

  • 70 percent in Japan want end to nuclear power

    An NHK poll shows that nearly 70 percent of Japanese people want to reduce or abolish nuclear power in the future.

    NHK polled about 2,600 randomly selected adults nationwide over 3 days through October 28th.
    1,775 people responded.

    24 percent of respondents said all nuclear power plants should be shut down and 42 percent said the number should be reduced.

    23 percent said the existing facilities should be maintained and 2 percent said they want more nuclear plants.

    49 percent of respondents said they are very afraid of another nuclear accident and 37 percent are worried to a certain extent.

    When asked if nuclear power generation will become safe in the future, 46 percent said yes and 48 percent said no.

  • Shareholders to seek money from TEPCO managers

    Tokyo Electric Power Company shareholders are poised to launch court procedures and demand that the utility's current and former management return more than 14 billion dollars to the firm.

    About 30 shareholders plan to file a class-action lawsuit against roughly 60 executives who worked at TEPCO over the past 2 decades.

    The investors say they will take legal action if the company refuses to demand that the executives return the large sum of money.

    Observers say that if the shareholders go to court, the damages they would seek would be a record high in Japan's judicial history.

    The shareholders claim that TEPCO executives failed to take adequate safety measures to protect the plant from an earthquake and tsunami waves.

    One investor said that the executives repeatedly emphasized the safety of nuclear plants. However, the accident has caused irreparable damage.

    The group claims that at shareholders' meetings the executives never heeded the safety concerns discussed involving nuclear power generation.

    TEPCO says it can't comment on the lawsuit until it knows more details.

  • The good burghers of this country seem to be exposed to the same business practices as used in Japan when it comes to reactor restart. I found this report on the last North Anna public meeting in the Daily Progress under the headline "North Anna reactors could restart next week" www2.dailyprogress.com . The most remarkable part of the article is this comment:
    Posted by DOP on Nov. 3, 2011 - 9:56 a.m.
    This article states that most folks at the meeting stood up when asked by a Dominion employee if they favored restart. It is important to point out that many in attendance work for Dominion or other companies tied to the nuclear industry. A Lynchburg-based company bussed in its employees who donned "Nuclear Power" t-shirts.

    I wouldn't be so quick to assume that most folks who live around the plant favor restart. At a previous public meeting, a number of Lake area residents expressed concerns. Please speak for yourself and don't assume everyone agrees with you.
