Japan Doubles Fukushima Radiation Leak Estimate

DrBoumBoum writes "The severity of the Fukishima disaster continues to go up, from incident level 4 to level 5 to level 7, and now to 20% of total Chernobyl radioactive spill. The story is not over yet as the plant keeps on leaking radioactive material and may still do so for a long time."

    There is ongoing self sustaining fission at Fukushima according to multiple sources: http://www.nakedcapitalism.com/2011/06/guest-post-are-nuclear-reactions-still-occurring-at-fukushima.html

    Today, Tetsuo Matsui at the University of Tokyo, says the limited data from Fukushima indicates that nuclear chain reactions must have reignited at Fuksuhima up to 12 days after the accident.

    As Time Magazine blogger Eben Harrell pointed out on March 30th:

    The IAEA has said that the Fukushima nuclear power plant may have achieved re-criticality. “There is no final assessment,” IAEA nuclear safety director Denis Flory said at a press conference on Wednesday, according to Bloomberg News. “This may happen locally and possibly increase the releases.”

    Arnie Gunderson says as of June 3rd:

    Unit 3 may not have melted through and that means that some of the fuel certainly is lying on the bottom, but it may not have melted through and some of the fuel may still look like fuel, although it is certainly brittle. And it’s possible that when the fuel is in that configuration that you can get a re-criticality. It’s also possible in any of the fuel pools, one, two, three, and four pools, that you could get a criticality, as well. So there’s been frequent enough high iodine indications to lead me to believe that either one of the four fuel pools or the Unit 3 reactor is in fact, every once in a while starting itself up and then it gets to a point where it gets so hot that it shuts itself down and it kind of cycles.

    Another recent post points out:

    Radiation levels in water inside the silt fence near reactor 2 are high and rising, despite large amounts of dilution. Continued very high levels of Iodine 131 with a half life of 8 days are very hard to explain for a reactor that has been “shut down”. Normally Iodine levels would drop several orders of magnitude below cesium activity levels over the sixty day period shown in the graph, but instead they continue to track each other. The level of 10,000 Bq/liter I-131 is very problematic. It is much higher than would be expected for a reactor in cold shut down for 2 1/2 months.

    The situation at Fukushima is not stable and in fact the danger is increasing. The stopgap cooling by injecting tons of water into the reactors and fuel rod storage is creating a massive burden of highly radioactive water that is a storage and disposal nightmare. There has been some limited success in providing recirculation cooling to the spent rod pool for unit 1, but that has a modest effect on the radioactive water situation.

    The plan to reduce radioactivity in existing water and recirculate it for cooling is still in process. It is not clear if the capacity of this system will be able to keep up with current cooling needs, much less deal with the backlog. If the reactors and fuel storage are generating new radioactive material, the cleanup system is even less likely to be adequate.

    If there is re-criticality the cleanup becomes that much harder. There is also the possibility of more fires/explosions because of radioactive decay heat sources. Continued earthquakes or typhoons could trigger other large release of radioactive material into the general environment.

    The plant is leaking highly radioactive water right now and this problem is being swept under the rug. There will be a permanent exclusion zone at the plant site. Even worse, the ocean region will have long lasting radiation contamination that will cripple the seafood industry for a large area of the Japanese coast. Things are a lot worse then anyone is willing to admit.

If true, providing a reliable source would greatly strengthen your argument at large, and I think that would be a good thing.

    That German AVR reactor is also the most heabily beta-contaminated reactor site on the planet. And it contaminated both the soil and groundwater, and better yet in the form or radioactive dust.

    Melting down is not the only possible problem...

    You make a good case, and you probaby would like this book by Bernard L. Cohen that says much the same:
        http://www.phyast.pitt.edu/~blc/book/BOOK.html

    Also, at some point, even with meltdowns, we can just site new nuclear plants where the old one melted down. So, Fukushima is now a good place to site more plants, as is Chernobyl, given the evacuations and the grounds are already contaminated. We could also produce synthetic fuels in those areas and ship them elsewhere. And we could build lots of robots to do the work.

    Thorium reactors are even safer and we have much more thorium (thousands of years) than uranium and plutonium (hundred years?) for reactors.. But ironically it is said that thorium technology was not developed in the 1940s and 1950s precisely because it was safer and you could not make bombs from it.

    With all that said, I'm still rooting for stuff like solar roadways, maglev wind, or the Rossi/Focardi eCat.

    Even various forms of hot fusion are looking promising.

    Although solar thermal could have done the job from the 1970s and on. Renewables IMHO have been cheaper than fossil fuels when you consider the externalities like pollution, health impacts, risks, defense costs, and so on.

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

    One can argue about the externalities from different nuclear options (such as who pays for the permanent evacuation around Fukushima or follow on effects like loss of agriculture or other economic problems in the area). If we do see a nuclear resurgance, it is going to look very different than today's plants (or should).

    Conventional nuclear tends to be fairly centralized which has various political implications in a democracy. Yes there ideas like Hyperion, but they still probably require big central plants to make them and reprocess them. Mainstream nuclear in general requires a higher level of transparency then our society seems capable of on a sustained basis so far. Fukushima is just one more example of that lack of transparency or foresight.

    Still, it's a bit of a chicken-and-egg problem, as if our society ran off of cheap thorium power, our politics might be better and less short-term if it assumed abundance instead of scarcity.

    The good news is, we have lots of energy options, and the human imagination continues to invent more of them:

    You make some good points here but I think your arguments would be much stronger if you discuss:

    a) why the nuclear industry has consistently downplayed the severity of the incident at every turn (meltdowns more severe than 'expected', more radiation released than 'expected' - why aren't they honest and releasing worst case figures?
    b) why the industry keeps talking about 'design flaws' instead of acknowledging irresponsible cost/risk management practices
    c) discuss the social and economic impact of displacing 100,000 people and how this factors into the cost of nuclear

    The way the vast majority of nuclear engineers and supporters ignore the negatives and focusing solely on the positives gives me the impression that the industry has a far too narrow focus on certain technical issues and are blissfully unaware of the real and perceived impacts of nuclear technology on the economy and society generally. Before and even after this incident I was a supporter of nuclear energy. However, the industries response to this disaster has pretty much convinced me the industry is incapable of running a nuclear enterprise responsibly.

    from nuclear power ? 0 (*one* got mild burns and *may* get sick in 20-30 years)

    In the interests of strict accuracy that would be no deaths caused by radiation (so far at least). There was one as a direct result of the earthquake and two from the tsunami. (Even so, compared with other places on the coast that would make it a relatively safe place to be.)

    So it's magic huh? It effects the environment. Perhaps not in the way that combustion does, but there are still outputs that apparently are dangerous enough to warrant centuries long storage. That we don't store anywhere except at the very sites where the possibility of meltdown and explosions are.

    You know, this criticism *was* adressed in the original post. You see nuclear waste is much less dangerous than the inputs to the plant. Natural uranium ore would qualify as highly radioactive waste and ... we don't actually store it anywhere safe. It just sits in the ground, sometimes in contact with ground water ...

    But once that uranium ore is passed through the nuclear chain, there's MUCH less of it around. So in reality, nuclear plants reduce the amount of highly radioactive "waste". As an added bonus, we store it safely instead of randomly.

    Oops.

    I find it cute how people keep claiming wind and solar are the answer ... when the actual devices involved in both cases are made 99% of oil (solar panels, and that's not counting the massive amounts of coal needed to produce the silicon wafers) or 50% oil 50% coal (read up on how metal is manufactured). You're replacing "very dangerous" hummer with a ... hummer.

    And most solar panels take years to even earn back the energy investment it took to create them. And in actual weather, they last 5-10 years at best, and somehow neither transport, nor installation, nor maintenance are counted to that energy investment. Of course, transporting a solar panel from Germany to California (which was 50% of the market at one point) takes twice as much energy as producing that solar panel ... this means that there are millions of solar panels installed in California which actually ... increase and accelerate fossil fuel use. And this is being polite and assuming *theoretical* maximum production levels that you wouldn't be able to match in practice even on the equator.

    Solar/wind (unless major advances in technology are made) are in reality worse than oil.

    At current technological levels wind/solar is a disaster, worse than doing nothing. Not that such details matter to the masses of sheep that call themselves "environmentally conscious", laughing and congratulating themselves while destroying more of the environment than their loved hummer driving champions. Their champions, like Al Gore or Obama preaching CO2 savings are about as credible as Snoop Dogg preaching abstinence.

    But hey, they get to feel good about themselves. While they're destroying the environment ...
