Asahi: Radioactive contamination ‘soaring’ in Fukushima groundwater — Strontium and other beta emitters up 4,500% in recent days; Cesium rises nearly 1,500% — Tepco says it doesn’t know why levels spiked (VIDEO)

NHK, Aug. 6, 2013: […] on Monday, TEPCO detected high levels of radioactive substances in groundwater collected at a monitoring well close to the turbine building of the No. 2 reactor where highly radioactive water accumulated in its basement. The level of radioactive cesium was 14 times higher [960 Bq/L vs 65 Bq/L] than the reading logged last Wednesday. Strontium and other radioactive materials that emit beta rays were 46 times higher [56,000 Bq/L vs 1,200 Bq/L]. TEPCO officials say they do not know the cause for the spikes, and they will further look into how contaminated water has spread and what effects it has brought.

Asahi Shimbun, August 6, 2013: Radioactivity levels soared 47-fold over just five days in groundwater from a monitoring well on the ocean side of the crippled Fukushima No. 1 nuclear power plant, the plant operator said Aug. 5. Tokyo Electric Power Co. said 56,000 becquerels of radioactive substances, including strontium, were detected per liter of groundwater sampled on Aug. 5 in the “No. 1-5” monitoring well, which is adjacent to the turbine building for the No. 1 reactor. The previous measurement for the well water was made on July 31. […]

Tepco Press Release, Aug. 5, 2013: […] the latest situation concerning the detection of high densities of Tritium and Strontium in the observation hole at the east side of the Unit 1-4 Turbine Buildings […] Groundwater observation hole No. 1-5 (west of the groundwater observation hole No.1-3)

  • Aug. 5, 2013: Cesium-134 @ 310 Bq/L; Cesium-137 @ 650 Bq/L; All-β @ 56,000 Bq/L
  • July 31, 2013: Cesium-134 @ 21 Bq/L; Cesium-137 @ 44 Bq/L; All-β @ 1,200 Bq/L

    Huge rises in radiation leves. Steam coming from turbine buildings.

    One and one equals two – re-criticality.

    • We Not They Finally

      That's what I was thinking: RE-CRITICALITY. And how can they stop the fissioning from the coriums underground? They can't.

  • razzz razzz

    Recent quakes or construction disturbing weak concrete tunnels, joints and unstable melted core material?

    Would this be a good time to ask for some outside help?

    These latest tactics to fix a bad situation is making everything worse. They are going to turn the site into The Daiichi Slough with this trial and error approach.

    I think they need to stop what they are doing and concentrate on stopping the water flow and get the site ground dry. They will never stop it all but at least can slow it down. They haven't done much to stop the water at its source when entering the site uphill. They elected to start damming downhill first.

    • We Not They Finally

      How would a DAM even help if the water is pouring through UNDERGROUND? And how would they get to the radioactive hell underground at all?? And how do you get ground "dry" when 400-plus TONS of more water is rushing in every day?

      Everyone wants to DO SOMETHING. That I get. But since they CANNOT stem the tide, apparently what has been chosen is to frighten us, and possibly deliver death by other means. We were horrified to learn of the new announced "worldwide global travel alert and terror alert" — no time no place, no means specified. Just that AL QUAEDA has something ghastly planned?? That there is "intelligence" that anyone anywhere in the world could be in deadly danger at any time, but the fault will be ANYONE BUT US? Go blame Al Quaeda?

      We have so "had it"!

    I know this was already reported on One quake too many?

    5.8 magnitude earthquake strikes off northeast coast of Japan

    • We Not They Finally

      I don't know how they measure UNDERGROUND damage. The coriums are flowing underground. I would think that earthquakes would only make that bad situation worse. Would be interested to see feedback on that.

    If TEPCO's estimate that 400 tonnes of groundwater enter the plant every day is accurate, then TEPCO plans to divert into the ocean 1/4 of the total groundwater flow, beginning by this weekend.

    "A Tepco official said on Monday the company plans to start pumping out a further 100 tonnes of groundwater a day around the end of the week."

    This water would be tested, then dumped into the Pacific.
    The rising water at the site is due to the construction of an Impermeable Wall along the harbor, which is about half complete at present.

    IMO, TEPCO is making a big deal over the rising groundwater, because this is something that can easily be remedied. Pumps are already in place, as will be seen when 100 tonnes a day is diverted into the ocean. Also, TEPCO's admissions and apologies for high groundwater contamination levels might be the first step towards a public announcement that some corium from Units1,2,&3 is in the ground underneath the plant.

    What is the condition of the stored used rods in all units???

    Were there not rumors of stored nuke bomb material in FUFU #3???

    • PhilipUpNorth PhilipUpNorth

      Ftlt: begin here with the official report on conditions in the SFPs.
      IAEA, bleah! Had to go wash my hands.
      TEPCO is wrapping up construction on Unit4 Crane Support Structure, and will begin to remove spent fuel shortly.
      They expect no problems. TEPCO has tested the water from SFP4, and insists no damaged fuel assemblies are indicated.
      I expect that many of the fuel assemblies in the SFPs will turn out to be damaged, by dewatering, fires, heating, explosions, falling debris, or saltwater. If I am correct, handling them will be problematic, perhaps some will dump their fuel pellets into the SFPs, and cause criticalities. SFP4 will be emptied in 2014, so we will know soon what to expect. The CSFP will be emptied of all sufficiently cooled fuel assemblies. These will be transferred to dry casks, which will be stored in a new dry cask storage facility, to be built. Trucks will move dry casks around the site.

    uh..and the 100 tons of water is to be filtered? Just how do they plan for that. I see a 'wink wink' going on, and just unprocessed radioactive water dumped. Just like they have been doing all along.
    Interesting, strontium is finally being mentioned..but not HOW MUCH, just Cesium. Drip for it soon..4500 percent increase means someone is tracking the contamination. Soon it will be SURPRISE..we just found out that bad company,TEPCO, lied again and now the GOVERNMENT (The great white knight) will take over..?? Everyone seems to be ignoring the government was to be in charge a year ago or at least months ago. Guess it took Japan months or years to figure out the best way to present their failure… the fatally irradiated public in Japan..and in the rest of the world.
