Emergency mail from Tepco to Mass media about reactor 4, Fukushima Diary, Jan. 1, 2012:

Notice from Tepco

For massmedia

This mail is sent to people who registered to the service to receive messages late in the night / early in the morning.

17:30 1/1/2012 , Tepco employee found the water level was decreasing faster than usual in the tank to keep the overflowed water from spent fuel pool of reatcor4 [sic].

The water level is decreased naturally because of water evaporation, as it used to take 3 hours to be decreased by 50mm (17mm / h), but from 2PM to 5PM today, it was decreased by 240mm within 3 hours.(80mm / h). […]

      This is what Arnie Gunderson said was his “big concern” several months ago, i.e., that there would be another large EQ and SPF at #4 would be compromised. Oy vey, time to start praying. (I’m not Jewish but it certainly seems appropriate to say, “Oy vey” at the moment.)

        Indeed HoTaters,….”Oy vey”! May YHVH’s love be with us all, in order to ‘go through THIS’! Amen

  • Grampybone Grampybone

    The quake must have caused some damage to cause this amount of water to leak. Where is the water now? Can the utility keep coolant flowing to prevent a fuel pool fission event? If the water all leaks out and the spent fuel begins to produce heat and gas we have a huge freaking problem. The structural integrity looks compromised from the shaking.

  • sworldpeas

    240mm= 9.44881′ every 3 hours?! I feel a check-mate coming on…

      could the water temperature be effected by the filter that needs unblocking that was reported here on enenews? repair supposed to be fixed in january 3rd? i ithnk? when everyone comes back from holiday!

        “We are conducting the survey of the area with the expectation that there is a leak somewhere. So far, there is no leak on the 1st floor of the Waste Product Process Building where the cooling system for the Reactor 4 SFP is installed, and no leak outside the reactor building. We will investigate the pipe joints inside the reactor building for any leaks, and identify the cause.”

      80mm per hour = 8 cm per hour. 1,000 millimeters , or 100 centimeters per meter.

      100cm/8 (cm per hour) = 12.5 hours to drop by 1 meter.

            In Fuel-Cooling Pools, a Danger for the Longer Term

            “…That means that in normal operations, the spent fuel is covered by about 30 feet of cooling water….”

          • HoTaters HoTaters

            Thank you. It’s anyone’s guess if there have been anything like “normal operations” lately. It’s good to know if there were anywhere near 30 feet of H20, it gives the management/workers a little time to try to come up with an emergency strategy. Nonetheless, that only gives them a few days to build something ASAP, which isn’t much time. The engineers and site personnel will have to work 24/7 on this one. I wouldn’t want to be in their shoes right now. My guess is personnel are probably being called back from vacation early, if they were on vacation …. (Do the Japanese celebrate the New Year on the same date we do?)

    While we are following the latest news, the Telegraph ( UK) is reporting today that thousands of Japanese tourists have returned to Fukushima to ski. The ski resorts are at 70% occupancy.

    • Toadmac

      I thought TEPCO were over exaggerating the problems at Fukushima #1? It would seem people are falling over each other and flocking to Fukushima? Must be some sort of misunderstanding? In Australia on the MSM’s looking back at 2011’s major events and disasters programs (which I was looking forward to watching and you guys know why). There were many events and disasters in 2011 on both programs I watched, including a large mention on rebuilding Japan after a big earth quake. My attention was so focused on these two programs on different channels,I must have missed the “nuclear accident” parts? Strange that!

    • GreenParis

      “The ski resorts are at 70% occupancy.”
      Actually, they say that 70% is the max, so in one place only. Typical marketing speak, i.e. a lazy journalist copying a figure from the pre-written article sent by a Public Relations agency in Japan, a journalist too lazy to ask for all the figures to find out the average occupancy. Max 70% probably translates to a less than 50% average, meaning that 1 in 2 Japanese refuses to go on holiday in radioactive snow. And of course not a single interview of a Japanese who went there on holiday last year and is afraid of going back this year and stays home instead, preferring to spend money on buying imported water and food.

            I think you are expecting a different headline. It was buried in this piece about transmutation. I found it when I was researching the practice of transmutation to get rid of nuclear waste. I big sham like everything the nuclear industry does.

      Transmutation on the Ocean Bottom
      June 20, 2011

      “With the large releases of methane under the Gulf of Mexico by deep drilling and nuclear fracking of the basalt plain large quantities of methane ice have piled up on the bottom. Given time the bacteria will eat all the methane keeping the Gulf deep waters cool and making a lot of fish food. The use of Corexit emulsifier sinking the red coloured petroleum to the bottom will in time be transmuted by the bacteria.

      “The radioactivity in the petroleum, fall-out from the August 19 2009 nuclear blast 10 kilometres under the alluvial fan of the Mississippi will also be transmuted by the bacteria. In biological systems radioactivity drops fifteen times faster than in a test tube.

      “The practise of the US Navy to drop decommissioned nuclear reactors in the ocean depths may be the best solution for long term elimination of such materials. The bacteria eats the iron into “rusticles” as seen on the Titanic at 10,000 feet deep and transmutes toxic radioactive elements fifteen times faster than in underground bunkers….”

    Pool No. 4, published analysis of the risk of damaging the fuel at one o’clock in June

    Nuclear power plant

    “Nuclear and Industrial Safety Agency, METI 14th aftershock broken fuel storage pool of Unit 4, Fukushima Daiichi Nuclear Power Station Electric Power, once unable to cool the fuel, it will begin to leak radioactive material in more than two hours announced the results of that analysis was the end of June.

    “At the time the earthquake occurred East, No. 4 fuel pool is a spent fuel 1331, 204 came in a new fuel. An explosion occurred in an accident, blew the walls of the building of Unit 4. TEPCO then the strength of the pool, and evaluated to withstand the aftershocks that without reinforcement, construction began on seismic as a precaution.

    “On the other hand, assumes that NISA are cracks in the pool before going on to complete reinforce aftershocks. Water leaking fuel cooling pools that were estimated to 冷Yasenaku if at all. The temperature reached 900 degrees, 2.3 hours after the leak of radioactive material to cover the fuel pipe is damaged, was 7.7 hours after the onset of fuel melting is reached at 2800.”

  • jackassrig

    That structure was so weakened by the first earthquake, explosion, tsunami, and radiation that the TEPCO would need to stiffen the SFP enough to get the natural frequency much higher than any frequencies the earthquake can produce or the SFP will collapse. The waves from the earthquake reach out from the center much like a pebble dropped in water. The amplitude will decrease the further the wave extends from the center due to damping but the frequency remains the same in spite of the damping. So if the frequency of any of the waves the earthquake generates hits the natural frequency of the SFP the displacements will tend to infinity-theoretically. I don’t think the Japanese had time to analysis the structure and add the proper stiffening. The SPF would need to be modeled using SACS or some other FEA program so the bracing can be added in the proper places to stiffen the structure…

    • Dr. Anne Lee Tomlinson Maziar anne

      I think the problem is with the pipes used to fix SFP #4 after the Mar. 11 earthquake. They are not earthquake-proof. I think I heard that is Arnie’s last video. When the pipes break the coolant leaks out.

  • jackassrig

    . I think they may have scabbed in a slew of steel hoping they could stiffen enough to miss any frequencies the earthquake can generate. I don’t see any reason to stiffen the SFP if the building topples down on top of the pool. With the wall of the #4 leaning the foundation has been undermined or the poor structure is slowly giving up to so much abuse. TEPCO certainly cannot stiffen the building. That’s out of the question. I think this adding reinforcement is another way of showing that TEPCO is trying to do something. I hate to sound so damn pessimistic but I think it was an exercise in futility for TEPCO to try to shore up the SFP. IMO.

  • lokay5 lokay5

    I think EVERYTHING TEPCO is doing, and has done, is an exercise in futility. A fucking TENT? Get real, TEPCO!

    • americancommntr

      I get the notion that the Tepco organization must have all the time recruited by cronyism and nepotism, and not merit, so that nothing gets done right and decisions are made by people of low intelligence, wisdom, and knowledge.

      Of course, as the Russian scientist said about Chernobyl, it looked like a neutron bomb had destroyed the area, and that’s probably the real truth at Fukushima. How could it not be? Then ‘cams’ showing green trees, etc., is probably all fake.

      Even those promoted by merit would have little they can do with current technology being used.

  • James2

    #4 SFP is steaming like mad right now. Possibly spewing iodine.

    It’s getting really hot. I suspect it’s in the process of collapsing – don’t know whether that will be a quick process or a slow one…

  • tinkr55

    Reactor #4 as been leaning like the Tower of Pisa for months now. If its’ corium has melted through the bottom already (if we know), what would be the probable outcome if it finally collapsed in on itself? I thought for sure that the next slightest quake would topple it, but it is still standing, if steaming, after last night’s substantial quake.

  • dodge

    Long term danger is great, should they completely lose ability to stay near and cool this waste fuel, however, the immediate concern is where is all this highly radioactive water going, and can the leak be stopped. I hope we don’t see the fire trucks spraying sea water continually with the overflow returning to the Pacific.

  • Quake Causes Leak At Fukushima Unit 4 Spent Fuel Pool

    (It’s a slow link, so may have to try several times).

  • Water leakage at Fukushima reactor 4

    At approx. 5:30 pm on January 1, 2012, we observed approx. 240 mm decrease in the water level of the skimmer surge tank *1 of Unit 4 spent fuel pool in the three hours between 2:00 pm to 5:00 pm (According to the operation record so far, there had been an approx. 50 mm decrease.). As a result of the site investigation later, we did not observe any leakage around the Unit 4 reactor building, connecting points of primary system pipes of Unit 4 spent fuel pool alternative cooling system, or its installation space.

    The water temperature of Unit 4 spent fuel pool as of 5:00 pm on January 1 is 23°C (22°C as of 5:00 am on January 2). The spent fuel pool alternative cooling system is still in operation and there is no problem in cooling the reactor. Though the water level of the spent fuel pool is kept stable without any problem, the water level in the skimmer surge tank continues decreasing. Therefore, from 10:27 pm to 11:13 pm on January 1, we filled water in the skimmer surge tank. At present, the water level in the skimmer surge tank keeps decreasing approx. 90mm/hour. We will strengthen surveillance on observation of the water level in the skimmer surge tank, increasing the frequency to once in an hour from once in three hours. At the same time, we will continue examination of the causes of the decrease in the water level, such as site investigations based on such possibilities as the water may flow into the reactor well *2 from the spent fuel pool. At present, no leakage is observed outside the building. No significant change is observed in the water level of the accumulated water in the building.

    “The water level is decreased naturally because of water evaporation, as it used to take 3 hours to be decreased by 50mm (17mm / h)”

    Did anyone find this definition of “normal evaporation” a bit odd?

    According to this, the level drops about 1.5 feet daily because of “normal evaporation”.

    The pond outside my window might drop 1.5 feet in the entire month of August, if there is no rain. Water doesn’t “normally” evaporate a foot and a half per day in December/January. It’s either “normally” leaking dramatically or boiling or both.

    That’s before this newest development.

    This is how “bad” becomes “normal” over time.
