  • Good morning good people. Just on the fly. The way I understand rad level monitoring in the drywell is that air samples are drawn from pipes that split into smaller and smaller diameter producing increasingly higher ranges by reducing the volume of sample measured. Similar to a GM tube, the detectors I know need high voltage to reach a plateau on which they operate (e.g. PM tubes). Perhaps the oscillations are due to a temporarily unstable high voltage supply. As to control room instrumentation, my guess is that the original set was never fully replaced, but modern equipment simply overlays the old.
    As to Orion, isn't this Dietmar Schoenherr und Eva Pflug? I still remember the theme music. Orion was a great series.

    School buildings decontaminated in Fukushima

    Parents and teachers have worked to remove radioactive substances at elementary schools in Fukushima Prefecture ahead of the reopening of classes later in the month.

    Twelve elementary and junior high schools in Minami Soma City will restart classes on October 17. The government lifted an evacuation advisory on Friday for areas outside the 20-kilometer no-go zone around the troubled Fukushima Daiichi nuclear plant.

    On Sunday, more than 70 teachers and parents worked to decontaminate classrooms and the gymnasium at Ohmika elementary school, located about 21 kilometers from the nuclear plant.

    Parents wearing masks sprayed detergent over windows and walls of the gymnasium and then wiped it off with rags.

    In classrooms, they used vacuum cleaners and brushes to clean up dust piled on window frames.

    One parent said he will work hard because children are happy to go back to school. Another said he is still worried about radiation, but that he will have to look forward and move on.

    The number of students at Ohmika elementary school has declined to 71, one-third of the figure before the nuclear accident. The school says 6 students will return when it restarts classes.

  • Govt to financially help less contaminated areas

    Japan's minister in charge of the nuclear disaster says the government will provide financial assistance for clean-up efforts in municipalities where radiation levels are below 5 millisieverts per year.

    The Environment Ministry was criticized for its decision late last month not to offer financial help to such municipalities, except when cleaning ditches and other highly contaminated spots.

    Cabinet minister Goshi Hosono met Fukushima Prefecture Governor Yuhei Sato on Sunday.

    Sato said many people in his prefecture are wondering why they have to clean up the contaminated areas by themselves.

    He said he wants the government to understand that either the government or the operator of the nuclear plant should do the work.

    Sato asked the government to provide financial assistance when municipalities decide to clean up areas where radiation levels are between one and 5 millisieverts per year.

    Hosono said the government is responsible for cleaning up the contaminated areas, and those with radiation levels of one to 5 millisieverts per year qualify for the support.

    He promised that the government will provide financial and technical assistance if municipalities compile plans that show how they intend to clean up the contaminated areas.

    by Edano 10/2/2011 3:00:38 PM

  • EU's stress tests on reactors find no problems

    European Union countries that operate nuclear power plants say they have found no major problems with their reactors in safety checks mandated by the EU.

    The nuclear stress tests on 143 reactors in 14 EU member states started in June, following the nuclear accident at Japan's Fukushima Daiichi plant.

    The EU has carried out an assessment to see whether the reactors can withstand the effects of a major natural disaster, such as an earthquake, tsunami and flooding.

    In the first phase, plant operators in each country evaluated the safety of their plants by themselves, and the government compiled initial results, which were submitted to the EU by Saturday.

    France says the chance of a major quake and tsunami are almost zero. The country has 58 reactors that generate 80 percent of its energy consumption.

    French officials say that safety is secure at all 58 reactors, and that no emergency measures are required.


    Germany, which has decided to shut down all its nuclear plants by 2022, says safety at its reactors remains high.

    Nuclear regulators in each country are to assess their reactors, which will be then verified by a team of experts and authorities in surrounding nations. A final report will be issued before EU leaders meet in June next year.

    by Edano 10/2/2011 3:08:40 PM

  • @Edano so the stress tests covered maybe someone spilling a soda on their desk. :-)

    TEPCO's report is also useless. It sounds like it just repeats the corporate line everyone knows is BS, that the tsunami caused all the problems
    by lillymunster 10/2/2011 3:09:41 PM

  • @Edano , I just don't know. I read about monitors mounted inside the drywell, but for example the equipment that measures the radioactivity in the effluent from the stack is installed outside the stack and is placed in a shielded box in the US to keep the bg low.
    by Peter 10/2/2011 3:10:39 PM

  • @lillymunster , edano as to seismic stress tests, I picked up a lot from this NRC meeting on North Anna. Turns out that quake magnitude is not of much value in the assessment, because of depth, distance and geology. What counts is the ground motion actually measured in the reactor building. The Virginia quake shook the turbine building (the location where motion was recorded) much more than expected. There was much debate about the value of these measurements at the meeting. The experts would have preferred measurements in the free field. Also motion and acceleration seem to make a big difference in damage. I am trying to locate data for Fukushima that can be compared to that collected at North Anna. The comparison should be interesting.
    by Peter 10/2/2011 3:18:08 PM

  • @dean thanks for the detector vids. I built the can contraption. The most expensive part was the meter. In total the setup cost about $25.-. Unfortunately, the output voltage seems more sensitive to temp than ionizing radiation. I am still working on it.;)

  • @Peter I think Elaine might have run across some seismic findings on Fuku. I will look through my documents pile when i get back later today.

  • Out for a while, back later today
    by lillymunster 10/2/2011 3:25:09 PM

  • @edano, back to the drywell monitoring, I'd think that if radiation levels really rose that much, even for brief moments in time, measurements at the effluent pipes that lead or used to lead to the stack and perhaps on the building floors themselves should reflect the increase to some degree. If the robots dropped instruments inside the buildings on their visits, we would know more.
    by Peter 10/2/2011 3:31:51 PM

  • @Peter yes ty, peter. i think the seismic intensity scale that they (jma) use in japan is way better than the geological magnitude. the world should adopt it.
    by Edano 10/2/2011 3:56:20 PM

  • i switched to the jma seismic information. the usgs data is not that important towards the plants.

  • @elainekirk i never heard of a unit called "gal".
    by Edano 10/2/2011 4:09:44 PM

  • The gal, sometimes called galileo, (symbol Gal) is a unit of acceleration used extensively in the science of gravimetry.[1][2][3] The gal is defined as 1 centimeter per second squared (1 cm/s²).

    The gal is named after Galileo Galilei, a physicist who made the first measurements of the Earth’s gravity.

    It can also be used to measure peak ground acceleration in earthquakes.

  • @elainekirk "Using test solutions containing various combinations of Ca and Mg, we found that Ca had little or no influence on Mg absorption, even through Mg depressed Ca absorption to a modest extent. Patients with end-stage renal disease, who had a reduced rate of Ca absorption (presumably due to deficiency of 1,25-dihydroxycholecalciferol) were found to have a severe depression of Mg absorption. On the other hand, patients with absorptive hypercalciuria and nephrolithiasis, who had an increased rate of Ca absorption, were found to absorb Mg normally. These results suggest that Mg absorption in the human is mediated by a transport process different from that which facilitates Ca absorption, and that normal Mg absorption may be dependent on vitamin D. Our results do not establish whether or not the normal intestine can absorb Mg against an electrochemical gradient." www.ncbi.nlm.nih.gov

  • Hi@all, have you seen this yet?
    www.criirad.org
    CRIIRAD (Commission de recherche et d’information indépendantes sur la radioactivité), said that the level of radioactivity made public after the accident in Marcoule were false. Studies have shown that the 4 tonnes of metal in the furnace had almost 500 times more radioactivity, 30 Megabecquerel instead of 63 Kilobecquerel, as the operator , a subsidiary of Électricité de France (EDF), a French company, originally had indicated.
    by Liz 10/2/2011 4:20:15 PM

  • In view of the widespread use of magnesium (Mg) as a nutritional supplement, we investigated whether Mg would affect the absorption of calcium (Ca) as the intestinal absorption sites for Mg and Ca differ.

    The intestinal absorption of Ca, using 47CaCl2 as the tracer, and metabolic balances of Ca, phosphorus (P) and Mg were determined in five adult males under strictly controlled dietary conditions in control studies and during Mg supplementation. Mg was given as magnesium oxide (MgO) in 10 studies during two Ca intakes: five studies during a low Ca intake of 241 mg/day and five studies during a normal Ca intake of 812 mg/day. Dietary Mg intake ranged from 241 to 264 mg/day in control studies. During Mg supplementation, the total Mg intake ranged from 789 to 826 mg/day.

    There was no change of the intestinal Ca absorption during Mg supplementation during the two Ca intakes. The only change was the higher 1-hour 47Ca plasma level in the 47Ca absorption studies during the high Mg intake. Urinary Ca increased during Mg supplementation only during the low Ca intake, the Ca balance became more negative but this difference was not significant. There was also no change in Ca excretion or Ca balance during the high Mg intake at the normal Ca intake of 800 mg/day. P balance studies showed a slight decrease in urinary P and an increase in fecal P, but the P balances did not change. Mg balances were negative in control studies during the two Ca intakes. Supplemental Mg increased both urinary and fecal Mg excretion and the Mg balance became positive, but these differences were not significant.

    The increased Mg intake of 826 mg did not affect intestinal Ca absorption determined with tracer doses of 47Ca during Ca intakes of 241 and 812 mg/day. www.jacn.org

  • @Peter something for you: www.ndr.de

    Bei dem verloren gegangenen Beweisstück handelt es sich um ein Haar, das zur Untersuchung zum Landeskriminalamt nach Kiel geschickt werden sollte. Es ist nicht mehr auffindbar. Das verlorene Haar beschäftigt nun auch den Landtag. Am 6. Oktober will sich der Innen- und Rechtsausschuss mit dem Thema befassen. Es sei ein ernster Vorgang, wenn bei Ermittlungsbehörden ein Beweismittel verschwinde, so die innenpolitischen Sprecher Werner Kalinka (CDU) und Gerrit Koch (SPD).

    Das verschwundene Haar sollte mit einer neuen Methode auf mögliche DNA-Spuren untersucht werden.

    Das Haar war 1987 nach dem mysteriösen Tod Barschels im Hotelbett sichergestellt worden. Es sollte jetzt mit einer neuen Methode auf mögliche DNA-Spuren untersucht werden. Das Haar soll aber nicht von Barschel stammen. Aufklärungbedarf sieht auch das Kieler Justizministerium. Bereits in der vergangenen Woche habe das Ministerium die Generalstaatsanwaltschaft gebeten, die genauen Umstände des Abhandenkommens des Asservats zu klären, sagte ein Sprecher. Die Untersuchungen dauerten an.

    www.ndr.de
    Umstrittenes Buch zur Barschel-Affäre im Handel

    Das Buch "Ein Mord, der keiner sein durfte" von Heinrich Wille erscheint am Donnerstag im Handel. Seit Donnerstag gibt es in den Buchläden das umstrittene Buch des ehemaligen leitenden Lübecker Oberstaatsanwalts Heinrich Wille zum Tod von Uwe Barschel zu kaufen. Laut ursprünglichen Ermittlungsergebnissen beging Barschel 1987 im Genfer Hotel "Beau Rivage" Selbstmord. Doch Wille, der den Fall später in Deutschland erneut aufrollte, sagt eindeutig, es sei Mord gewesen - und zwar ein professioneller Giftmord. "Einen Selbstmord können wir mit an Sicherheit grenzender Wahrscheinlichkeit ausschließen", sagte der 66-Jährige in einem Exklusivinterview mit der NDR 1 Welle Nord.
