More Bad News From Fukushima 268

PuceBaboon writes "Both Reuters and the BBC are carrying the story of an increase in radiation levels reported by Tepco for contaminated water leaking from storage tanks on site. When this leak was discovered almost two weeks ago, Tepco reported that the radiation level was 100-millisieverts. It now transpires that 100-millisieverts was the highest reading that the measuring equipment in use was capable of displaying. The latest readings (with upgraded equipment) are registering 1800-millisieverts which, according to both news sources, could prove fatal to anyone exposed to it for four hours. Coincidentally (and somewhat ironically), today is earthquake disaster prevention day in Japan, with safety drills taking place nationwide."

      Then again, it is a very interesting way of damage control. Simply bring equipment which can only measure up to the damage level we want.

      I cannot understand how a company can make such a mistake. This is the most severe radioactive problem at the moment, threatening to change a country for the next decades.

      They know how important this is, and fail to bring along the right equipment?

        It is all intentional and just a big game of what they can cover up and with which lies they can get away with.
        The whole Fukushima operation is just a big scam with Tepco and the government as key players.
        The current LDP government is financially supported by all major Japanese companies that are heavily involved in the nuclear industry.
        That was a very lucrative business because there were hardly any rules that could not be bend but that has all gone bad after the Fukushima disaster.
        The main objective for Tepco and the LDP prime minister is to get nuclear energy accepted again.
        Although there are many accidents and false reports, the national media does not pay much attention, fearing the wrath of the LDP patry and some of the major companies here in Japan. But that doesn't differ much from the US I guess.
        Also, the national television company is just another propaganda media outlet but may Japanese are not aware of this fact.

        Japan has a long history of cover-ups when the government and major Japanese companies are involved.

          The Japanese government already practically owns TEPCO because it had to nationalize it to cover the clean-up cost. They just don't have any administrative control or use their shareholder rights.

          So basically TEPCO is in charge but not paying the bulk of the bill. The situation is not unique to Japan, every country with nuclear power would be in the same situation if something like that happened because getting commercial insurance to cover the hundreds of billions of dollars it costs is impossible.

        It isn't damage control. It is technician stupidity. There are a wide range of radiation meters. But the type that can read up to 200 Rem/hr (2,000 mSv) aren't common. A typical meter won't even read up to 1 Rem/hr, because such high levels aren't common. Only casualty meters read higher.

        Any decent health physicist is acutely aware of where the meter saturates (which can sometimes be caused by the electronics itself--you really need to understand how your meter works when you adjust the scales).

        Simply bring equipment which can only measure up to the damage level we want.

        No, you bring the meter with the radiation you expect to find. If it is higher, you back out and bring a meter for that. If your readings are 50 mRem/hr at most points, it is ridiculous to carry around a meter than reads 0-200 Rem/hr. It is not precise. It is like reading the speed on your speedometer when it is calibrated in units of 500 mph.

          But it should be obvious to anyone that if your equipment pegs to 100mSv and no higher that something is wrong, and you shouldn't go to the media claiming 100mSv was the likely extent of the radiation levels in the leak.

            It must be a digital display, because you can clearly see when a needle (like a speedometer) is pinned.

            I think there is a real takehome lesson for designing instrumentation here. A device should not show the value "100" for "everything greater than 100." Under overload it should just show a row of hyphens or something. Even my cheap little digital kitchen scale does this.

          In the really real world, we practically never see a nice round number like that. We're always seeing fractions. So if the number was that round, then I'd check it again just to see if the meter was doing something weird. And if I got precisely the same completely round number over and over again, then I'd certainly suspect the results.

          Stupidity is too meek a word for this situation.

        In the measuring instrument business, you generally size the instrument to have a scale which is 50-80% of its range. So, for example, a speedometer for a Honda Civic might go to 140mph even though the vehicle is capable of only 115mph. It is bad to only use a very small % of the range of a measuring device for many reasons. If you have a speedometer in your Honda that goes to 5,000MPH, the accuracy at normal speeds is likely to suffer. If these were instruments for measuring leakage out of a storage ta

Just compare Fukushima fiasco to old commies handling Chernobyl. They did everything they could to NOT let this crap hit watertable. They've put liquid nitrogen injecting installation under the reactor to make sure it won't burn through the basement and won't contaminate ground waters. They've put 600 thousands people to work to clean up their mess (every man for one minute or so). Compare this to the crap, lies, corruption and cost cuttings TEPCO is doing on their site.

      These are really big doses we are talking about, in the range of what external-beam radiotherapy uses to destroy tumors. When stating that four hours' dosage at this level is likely to be lethal, this means "likely to be lethal by acute radiation sickness with death occurring in days." In reality, much shorter exposures are likely to be lethal from induced cancers (leukemia and thyroid cancers being common). It will just take longer for those people to die. I suspect that most of the workers who have been on site to this point have likely had their fates sealed.

    This is business as usual for Tepco, and the entire 'Nuclear Village' in Japan (the combined utility, industry, regulator and government group that controls nuclear energy in the country).

    This has been going on since before the plants were built. The reactors were so vulnerable to the earthquake/tsunami because they deliberately ignored the historical record of flooding in that part of Japan. The collective decision was made to ignore the worst case scenario.

    After the earthquake, flood and power outage, the upper management was incompetently slow to make decisions because they were unwilling to think about loosing the plants and the likelihood of radioactivity being released. It was only the heroic action of the technical team at the site that averted a disaster worse the Chernobyl. They ultimately had to disobey direct orders to save the situation.

    In the period after the so called 'shutdown' the authorities have been maintaining a delusional belief that they are doing an acceptable job and events are under control. Neither is true.

    Delusional thinking is supported by not doing obvious monitoring procedures. It's magical thinking: if they don't know how bad it is, then things must be OK.

    There is an ongoing failure to monitor radiation at the plant site, in the ocean and on the land. NGOs and international entities have been denied permission to do independent monitoring in the exclusion area and the ocean near the plant. One NGO Safecast [safecast.org] has been doing radiation monitoring outside the exclusion zone and making the data available.

    Quibbling about whether beta radiation is lethal is an example of delusional thinking. The fact that there are an entire spectrum of recently discovered radioactive water leaks is the critical information. None of these leaks were found in a timely manor. This happening two years after the reactor failure is appalling.

    Tepco does not know how bad things are because they don't want to know. The rest of the Nuclear Village is not much better. The Abe government is putting significant effort into trying to restart other closed reactors at the expense of dealing with Fukushima. The Nuclear Regulatory Agency has no credibility, because they have done almost nothing to make Tepco more responsible. Tepco and the NRA have been hiding as much information from the public as they can, so no-one believes anything they say.

    The prognosis is bleak. The situation is deteriorating, and two years have been wasted while ignoring the obvious. There does not seem to be any organization in Japan that has the leadership ability to manage the crisis. The likelihood of another very serious radiation leak is going up with time, not down.

    It is completely possible that there will be a dramatic failure and an internationally chartered group will take over long term responsibility. This is in effect what happened at Chernobyl. See New Safe Containment [wikipedia.org].
