  • General Daiichi Situation Summary 6/17/11

    1. Reactors 1-3 all ~100% Fuel Meltdown. All 3 RPV's have holes in them at various levels allowing

    highly contaminated water to leak out to buildings. Suspected Corium leaks from all 3 RPV's to torus,

    supression chamber and even concrete basemat. Large amounts of water need to be continuosly added to keep

    the mess cool. Reactors 4, 5 and 6 no known (or expected) problems.

    2. Spent Fuel Pools
    #1 Hot. Water being added to keep cool
    #2 Cooling provided by newly installed heat exchanger system
    #3 Hot. Water being added to keep cool
    #4 Hot. Water being added to keep cool. Structural damage known and being reenforced.
    #5, 6 and Common no known current issues

    3. All reactor/Turbine buildings have large amounts of Highly Radioactive water in their basement areas.

    4. Highly radioactive water has been transferred to the waste storage building (not tank) as temporary

    storage. This water is leaking out and all the turbine buildings are suspected of leaking to the sea and

    or groundwater.

    5. The radioactive water is an enormous challenge. They estimate they currently are dealing with

    ~100,000 Tons of highly radioactive water in the buildings and temporary storage tanks. This tonnage

    increases every day. For perspective, the 136-meter-long, 46-meter-wide mega-float can store around

    10,000 tons of water.Systems have now been put in place, and tested, to start treating this water. Their

    success will start to be seen in the next several days.

    6. The plant area is already plagued with a high (pre quake) ground water level.

    7. Reactor buildings all have extremely high radiation levels throughout, making stay/work times for

    humans very short inside.

    8. The site itself is highly contaminated and some areas have very high radiation levels associated with

    them. Some areas have been "plasticized" to render this radioactivity immobile, and this work continues.

    9. Several of the reactor buildings, spent fuel pools and yard areas continue to release radioactivity

    to the air, thereby adding additional radioactivity to the surrounding area and remaining population.

    10. An evacuation zone of 30 Kilometers has been established, most people have complied with evacuation.

    Some population centers beyond the 30Km have been directed to evacuate, compliance is somewhat less in

    these areas.

    11. People outside the evacuation zone are still having to deal with elevated radiation and soil

    radioactivity levels in their daily lives. These radiation and radioactivity levels do not impose

    immediate danger, but exposure at these levels will increase the risk of illness for these people. Some

    analysis of radiation hazard, indicates significant health risk at these low levels. Anecdotal evidence

    shows some indication of effects from low level radiation as far away as Tokyo.

    12. The people in and around the affected area are suffering, both mentally and physically, from the

    dislocation, fears and exposure to this Unprecedented (3 plants at INES 7) nuclear disaster.

    In closing, I haven't spoken of the massive tsunami and earthquake that occurred, and all the resultant

    victims and survivors, it is not out of a lack of compassion or empathy. My heart bleeds for these

    people, but that is a natural dissaster, the People of Japan know how to deal with it and will. Daiichi

    is a man made disaster that only required severe adverse nature to start the ball rolling.

  • Well take my name off whatever RBeaner is writing. Maybe I should wait to come back here until the issue of the other board is resolved.

  • @bobby please keep contributing your input is valued
    by elainekirk 6/17/2011 4:51:40 PM

  • @elainekirk It's becoming a moot issue anyway, I am so behind on everything else I was doing before I was so rudely interrupted by the global nuclear crisis, I have very little time now.
    by Bobby1 6/17/2011 4:53:40 PM

  • @Bobby1 This isn't a challenge by me to you. I want you and others to agree with the general wording. I changed it for your concern
    by RBeaner 6/17/2011 4:53:52 PM

  • @Bobby1 This (you and I) isn't about the other board. It is about a base philisophical or even medical difference of opinion on radiation effects. I can live with this dissagreement. Don't you think it makes us all (both) stronger.
    by RBeaner 6/17/2011 4:56:54 PM

  • @Bobby1 yes, I changed section 11 mainly for Bobby1's concerns, waiting for his review.
    by RBeaner 6/17/2011 4:58:59 PM

  • The site is loading very slow. I don't like "no immediate effects" period. Leukemia and thyroid cancer don't have the 10-year latency that other cancers do. And people (like me) with ankylosing spondylitis don't have latency at all.
    by Bobby1 6/17/2011 5:02:55 PM

  • "no immediate effect" is simply wrong. there are immediate effects in the form of defects. some may be repaired by the body, some not, and some accu mulate or even stray and lead to further defects.
    i think the keyword here is "defect". there are immediate defects to the organism but this must not lead to illness in any case. btw, it is a human right to have one's physical body protected from outer noxis.

  • @Bobby1 I retract my paer, I don't wish to be a lightening rod, nor do I wish to fill it with feng shui, I will stick with science. Just delete it and you all can avoid the controversy.
    by RBeaner 6/17/2011 5:12:26 PM

  • @ bobby@ rbeaner. I know it's not my argument, but most people should agree that there isn't a safe level of exposure to man-made radiation so it would seem safer to err on the side of caution rather than being too lax and realizing when it's too late that the exposure was worse than " thought"!@ edano. Exactly, put one living cell near ionizing radiation or some Gammas I'm sure there would be an effect.
    by NorthernCali edited by Edano 6/17/2011 5:13:15 PM

  • @NorthernCali So the cat is out of the bag, Radiation is bad.. Nowhere will you here differently. Now we have to deal with what is the relative risk.?
    by RBeaner 6/17/2011 5:15:17 PM

  • @Bobby1 @RBeaner I think what you need is to come to a compromise between the two perspectives of the same issue. Why don't you rewrite it to something neutral. We don't know for a fact that those radiation levels will cause future serious illnesses and we don't know for a fact that they won't. Rewrite it to something like, health hazard at the current radiation levels is still unknown. Compromise is the key. Neither of you is completely correct anyway. You're debating a grey area of modern science.

  • @RBeaner Well, I must agree with you. The very fact that we are here suggests that it isn't, since our planet has always had, at least, several microSv of background radiation since its conception. But there must be way of rephrasing that to accommodate Bobby's reserve concerning that issue.
    by Pedro Jesus 6/17/2011 5:26:37 PM

  • Biological effects of radiation on living cells may result in a variety of outcomes, including:

    1. Cells experience DNA damage and are able to detect and repair the damage.
    2. Cells experience DNA damage and are unable to repair the damage. These cells may go through the process of programmed cell death, or apoptosis, thus eliminating the potential genetic damage from the larger tissue.
    3. Cells experience a nonlethal DNA mutation that is passed on to subsequent cell divisions. This mutation may contribute to the formation of a cancer.
    4. Cells experience "irreparable DNA damage." Low level ionizing radiation may induce irreparable DNA damage (leading to replicational and transcriptional errors needed for neoplasia or may trigger viral interactions) leading to pre-mature aging and cancer.

    by LM 6/17/2011 5:28:11 PM

  • @ Pedro. What makes you think natural background and unnatural man-made fissile radioisotopes have anything in common other than the umbrella categorization as radiation.
    by NorthernCali 6/17/2011 5:28:49 PM

  • @Edano Absolutely not. And i give you that there will be increased Deaths as a resuly of this event.
    by RBeaner 6/17/2011 5:30:05 PM

  • @mark what is your opinion I am not techi but thought if seawater has entered the equation then they have problems.
    I wonder if a whistleblower led to kan stopping hamaoka restarting it was odd that he ordered it without nisa raising prior concerns

  • That's like saying all metals are harmless if ingested. But heavy metals will kill you while cast iron can be beneficial when cooked on.
    by NorthernCali 6/17/2011 5:30:58 PM

  • @NorthernCali If they have anything in common? They do. If they're exactly the same? They're aren't. Not all radioisotopes present in our planet are naturally occurring. Some of them were «man made». What's the aim of your question?
    by Pedro Jesus 6/17/2011 5:31:15 PM

  • @elainekirk : but elaine, salt in the core was the reason for shutting it down, or am i wrong ?

  • "Very Good News” Fukushima Unit 4 Pool Never Dry On June 15, 2011, the professional staff at the US Nuclear Regulatory Commission provided a brief to the commission. It was the second of three planned status updates on the Task Force Review of NRC Processes and Regulations Following Events in Japan. The briefing started with a report by Bill Borchardt the NRC’s Executive Director for Operations (EDO). Mr. Borchardt described the NRC’s current understanding of the condition of the reactors at Fukushima Daiichi, including the condition of the spent fuel pool for unit four. You can find the full 1 hour 45 minute video on the NRC’s public meeting archive. Here is the key segment regarding the condition of the facility.
