    Hmmm…given the close proximity of all the reactors to one another in a row, it'd be hard to tell which ones were leaking and if any weren't without seeing the leaks or having more precise ways to measure pressure, temps, etc. to make an educated guess. But, if this cesium 134 is from Reactors 5 and 6, and we also know that some of the Daiini reactors melted to some degree, then it's time for the Japanese public to stage a vigil outside the Diet until they get an accurate reactor accident count.

    • ForwardAssist ForwardAssist

      The Japanese people need to stage a nation wide walkout strike.

      Tomorrow morning the country should grind to a complete halt, no workers reporting for work anywhere in the entire country. No open stores, no cars driving anywhere. Grind the whole damn thing to a halt, raise your fists and your voices, and stand your ground until the government treats you like adults and equals. Enough of the lies, omissions, and obfuscations.

        A global strike is needed to end the nuke industry!

        • ForwardAssist ForwardAssist

          I don't want to end the nuke industry. I just want a new nuke industry that wasn't born of, and influenced by, the wicked desire to build atomic weapons.

          Liquid Fueled Thorium Reactors, or LFTRs, are the way to go. They are clean, safe, efficient, responsible, and offer a solution to our present waste stockpile.

          Please research the technology before writing it off. Clean and cheap energy can transform deserts into farms, transport the world, liberate human beings. I oppose water cooled reactors and nuclear weapons with every fiber of my being, but there is no free ride. Removing mountain tops, fracking, and deep water offshore drilling, are not the answer.

          Please keep an open mind and view at least one of these presentations. They are presented in varying length, and the longer versions are worth your time imo.

          "Kirk Sorensen @ PROTOSPACE on Liquid Fluoride Thorium Reactors"

          Condensed versions can be found in this playlist,

          It's worth noting that 97 percent of the world's rare earth market has been cornered by China. There is only one rare earth mine in the US, Molycorp, and they became operational less than six months ago. Rare earth mining is crucial to develop the US economy at this point.

            Without Price-Anderson support, the nuclear industry would collapse under the weight of the insurance it would have to buy. Without government guarantees that the waste would be taken care of, the industry would just shut down. Without a bomb, there is no reason for the government to give guarantees.
            Hydro, wind, and biomass are all cheaper than nuclear, even when the government guarantees are not factored in. Solar has achieved grid parity in some parts of the world, and will probably do so in the US within three years. There are a number of solar technologies that are being developed in the US that are less expensive than current technology and do not require rare earth elements.
            Battery technology is being developed that can store power from renewables to provide baseload power. Pumped storage can do the same already. Other storage technologies already exist.
            John Rowe, retiring CEO from Exelon, which runs ten nuclear plants, said he saw no future for it. Jeff Immelt, CEO of GE, says nuclear is hard to justify; GE does a billion per year in the nuclear market.
            Max Planck Institute says we can expect a major meltdown every decade or two. Two NRC safety engineers are whistle blowing because four nuclear plants could have Fukushima-style meltdowns if the dams upriver break.
            You want nuclear? Let me guess who your employer is.

              Guess all you want, but you'd be wrong. I'm a blue collar worker, far removed from any segment of the nuke industry. I have absolutely no investment in it, or it's subsidiaries, and I never have.

              None of those technologies you listed are a free ride, there is no such thing as a free ride.

            FA sez:

            "Liquid Fueled Thorium Reactors, or LFTRs, are the way to go. They are clean, safe, efficient, responsible, and offer a solution to our present waste stockpile"

            SP: The thread topic is cesium releases from Units 5-6.
            Please repost your comment to General Discussion so I (and others) can comment on thorium and TWRs being unsafe radioactive polluters.

            • moonshellblue moonshellblue

              I always thought they should have used LFTR's but right now we need to clean up the current mess we're in like cleaning up all our spent fuel pools, etc. I still think tidal power is a great alternative it's a clean energy source vs using anything radioactive. I used to be pro thorium but would rather see tidal, wind, and solar applications. Just my two cents.

          • "They are clean, safe, efficient, responsible, and…"

            "Clean and cheap energy can transform deserts into farms, transport the world, liberate human beings."

            That's EXACTLY what 'they' said about Atomic Power too.

            Remember 'Atoms for Peace'. (Pres. Eisenhower)
            Sounded good.

            Wind, wave, geothermal, solar and better efficiency are really the ONLY ways to go.

            If the monies spent on Nuclear had been sunk into the above technologies we wouldn't even need to consider anything else. We would be ahead of the energy game and leading the world. Instead our Military sold the 'be all powerful' idea to the politicians who then sold their souls, and your soul too basically, for a concept that was insane from the start.

            I am certain that you could install a small windmill and a solar panel on every home in the USA for less than the cost of "1" Nuclear Disaster.

    Never mind the spent fuel rods blown out of #3 for one to two miles out, most of it going into the ocean. Guess why TEPCO paved over the bottom of the harbor with CEMENT? IT was definitely NOT so that the fishies could have a freeway for their cars.

    Those highly radioactive fuel rods laying on the bottom of the ocean will continue to contaminate the ocean, and will continue to do so for eons.

    Of course, scientists do not calculate this or the leaks of radioactive water from the basements of reactor buildings or from the coriums underground at FUKU.

    According to the scientists and all of their 'simulations' and 'models' based on false assumptions, no facts and miscalculations, the Fukushima disaster is only 10% of Chernobyl. And Chernobyl killed only a few people, uh huh…

    Everyone has a choice.. the blue pill or the red pill… and whether or not to stay plugged into the Matrix.

    "Fukushima I Daiichi, Reactor Unit #5 and #6.

    Unit #5 was built by Toshiba Corp; unit #6 by GE Nuclear.

    Unit #5 had already been shutdown for inspection at the time of the earthquake. But nuclear fuel rods were already in the reactor vessel, and workers had to circulate water to cool them down.

    By 9 PM PT March 15, coolant levels had fallen in Unit #5. But the tsunami had damaged the diesel generator for circulating the water coolant. Pressure built up, so a relief valve was opened, thereby reducing coolant. To compensate, workers were using the diesel generator for reactor Unit #6 to pump water to cool both reactors.

    There were reports Units #5 and #6 were beginning to warm up. Its doubtful there enough volunteers on site to monitor all the plant instrumentation, turning off alarms, turning alarms back on, while addressing the continuous emergencies within the containment building?

    On March 16, 2:50 AM PT, Reuters reports water is being poured into reactors at Unit #5 and #6 (or perhaps the spent fuel pools).

    By March 20, the spent fuel pools at Unit #5 and #6 had been reduced from prior 65 C to 37 C and 41 C, resp., back towards the desired target of 25 C. Good news."

    Puzzling. The 5 and 6 units are two hundred meters from the other four. Perhaps it's another symptom of the megaplex syndrome.. namely too many problems in one complex. Perhaps 5 and 6 have been ignored and now they are a severe problem again.

    Yes, their pathetic number of workers (the number only) is working against final containment. Thousands of workers should be working on dry cask operations at 5 and 6 (plus the CSFP), but that probably is never going to happen. The complex will one day (possibly fairly soon) blow out of control and envelop all units.

      I think they used seawater which corrodes everything.

      • Dr. Anne Lee Tomlinson Maziar VanneV

        “…Crews had installed temporary submersible seawater pumps and hoses to supply cooling water to the residual heat removal system heat exchangers as the main seawater pumps were heavily damaged by the tsunami. Additionally, as there was heavy damage to electrical equipment in the basements from flooding, temporary power connections had to be made to the residual heat removal system main loop pumps. Temperature at Unit 5 pool decreased to 48 °C on 19 March 18:00 JST,[82] and 37 °C on 20 March when Unit 6 pool temperature had fallen to 41 °C.[46] On 20 March, NISA announced that both reactors had been returned to a condition of cold shutdown.[83][84]
        “On 23 March, it was reported that the cooling pump at Reactor 5 stopped working when it was transferred from backup power to the grid supply.[85][86] This was repaired and the cooling restarted approximately 24 hours later. RHR cooling in Unit 6 was switched to the permanent power supply on 25 March.[87]
        “On 28 May, the temporary seawater cooling pump for Reactor 5 stopped, which was discovered by TEPCO at 21 local time. At that time, the temperature in the reactor was 68 °C, and in the spent fuel pool 41 °C.[88] At 11 in the morning the following day the temperatures had risen to 92.2 °C and 45.7 °C.[89] Cooling was restored at 12:49.[90]
        “On 24 June TEPCO completed repairs to the Reactor Building Equipment Cooling Water system of Unit 5 which removes heat from the main Fuel Pool Cooling and Clean-up system as well as other…

      And then, they may have already put new fuel rods from #4 into #5 SFP.

    Could this be a result of the explosion that was caught on tape a few days ago.
    The debris seemed to be to the left of the camera but perhaps it came from reactors 5 and 6 and blew past the camera to the left.

    There is a good reason they are keeping those two reactors OUT of the picture!

      A giant out of control boiling pot of water would explain the camera jumping around the past week…
