Title: TEPCO considers net in nuke plant port to prevent irradiated fish from heading seaward
Source: AJW by The Asahi Shimbun
Date: December 04, 2012

Tokyo Electric Power Co. may string nets across its port at the stricken Fukushima No. 1 nuclear power plant to prevent fish contaminated with radiation from reaching the sea. […]

Sources said the company is considering setting up a 2-kilometer net at the mouth of the port and along the inside of the port’s levees. The measure would be accompanied with dredging of mud in the port. […]

At Fukushima, a vast amount of contaminated water that includes radioactive substances has been discharged into the sea […]

“We have been asking TEPCO to close the port after receiving data showing high levels of contamination,” said an official at a local fisheries cooperative. “There are openable nets that will allow dredgers to enter. TEPCO’s response is too slow.”

    What good is a net going to do? It won't stop all the contaminated water from getting into the ocean, it will contaminate fish outside the net. I'm not understanding the logic here, it seems like a waste of money and time, but that's just me.

  • weeman

    Maybe if it was semi permeable membrane that did not allow radioactive substances to be released and kept the contaminated fish in, I doubt that any fish in the vicinity will survive, but need to be disposed off as radioactive waste.
    What a joke, not funny, get with reality, I don't know what world you come from but not this plant, idiots.

    Radioactive contaminated water is spilling into the ocean from this nuclear disaster, and it seems that every country on the planet doesn't mind (one bit).

  • dosdos dosdos

    It doesn't matter how effective it is, it's simply a visible signal of effort being made so that they can say they're doing everything they can to fix it.

      I am significantly more supportive of TEPCO stopping plant outflows and debris incineration than I am of an idea of corralling fish. Silly me I guess.

  • Anthony Anthony

    Bad idea period. If fish want or need to migrate into the sea, that is their natural order and this should not be tampered with in the slightest. The fishes desire or need to move out to sea might also be their only way to survive the rising contamination of the inland waters. The issue is not so much the fish going out to sea as it is that the PLANT needs to come under some kind of real control and management.

    All through this the Japanese seem to be treating the symptoms rather than attacking the problem(s) at its root.

    Yep. I am beginning to understand japanese "high technology" approaches to "repair"

    In case of nuclear reactor meltout, throw a tarp over it until you can erect a shopping mall looking screen inclosure.

    When nuclear fool pool highly deadly radioactive cooling water and runaway highly deadly radioactive corium cooling water is difficult to contain, just let gravity take it to the nearest stream or ocean, and send the continuous highly deadly radioactive steam invisibly into everyone's atmosphere and lungs.

    When you sit on a cactus, always cut the needles off flush with the skin so no one will see them.

    Haven't posted in a while, but here's what it sounds like to me after reading the article. The first sentence about putting up a net to keep fish from LEAVING the port is fishy to say the least. Think about it…if there even are any fish in that port, they have been highly irradiated and probably wouldn't live long enough to bite a hook miles away (think…how far would you have to go from daiichi to find someone dumb enough to throw a line in the water for food?).
    Anyway, the point is, there's no damn fish in there, and if there is, there couldn't be enough to make any difference at all. Think…the fish are going to know that the water is terrible in that port, and I couldn't imagine there being any food in there for them. If they got near it, they would probably just swim away before even getting close to the port itself.
    So why do they want to put up a net? An obvious possibility would be to keep fish OUT of the port, not to keep them from GETTING OUT…but as I just said, I don't think TEPCO cares that much about fish getting into the port because if they did, they would have just poured a concrete wall across the small mouth of the port more than a year ago (or dumped enough of those concrete "Caltrops" across the opening to close it off like they did to the north-eastern part of the port very early on).

    The key, that I see so far, is that they mentioned the dredging…


    • MoonlightEmpire MoonlightEmpire

      The article mentions that they want to net-off the port AND conduct dredging operations…but they do not say why they want to dredge.

      I know that some of you think, as I do, that even if they didn't intentionally dump fuel rods/fragments/assemblies into that port early on in an effort to cool/sheild/hide them, large amounts of fuel went into that port (and the ocean around it) as a result of the explosions and the leaks/waste dumps that inevitably carried fuel fragments/particles with them.

      To conclude, my HYPOTHESIS is that they need to retrieve as much fuel material as possible from the muck in the port for some pressing reason (since they seem not to act even in dire situations). They want to dredge the port to get back some of the fuel, and they know that they will stir up a lot of bad stuff, so they need the net across the mouth to keep it from escaping the port and scattering across a much larger area that would make dredging for it impossible.

      Sorry to be so long-winded, but that's what I'm thinking. Just trying to make sense of this "brave new world".

      Best to those on ENE, and those across the world. Anyone with an extra room…offer it free to a japanese family with children. I'll sleep in a tent in my backyard and give them my room. Peace to the japanese, who are no different than you and I. Love. Goodnight.

        No personal offense, but do try to stay centered in reality. These people were not bright-enough to be able to purchase needed car batteries in the beginning days of the melt-downs. They are NOT smart enough to be so caught-up in absurd-fanatically fantasy-illusions. Please keep your ideas at least slightly planted in the earth and in reality, ok. (and don't yell at me. I do entertain occasional flights of fantasy too- but I do try to keep my perception and my views fact-based and science-based).

    I support this idea. It is a tiny step in the right direction. And that is the important thing. Those fish will just be food for other fish or humans and that gets into the whole bio-accumulation-bio-magnification thing. Granted. It is not a cure-all. It's just a tiny drop in the bucket of all the work that needs to be done. It doesn't address the issue of the radiation that is continuing to be discharged into the sea, …but… it is a valid idea and I think they should so this. Many of the Japanese people rely heavily on a seafood diet. We need to consider those people (who-ever might be left to survive) and give them some help in some way — however miniscule it might seem to us here in the USA. I support the idea fully. They need to put it in place ASAP! Again — it is a tiny step forward and this is what matters. (You cannot all just throw your arms up in the air and say it is helpless). Steps need to be taken!

    All of you seem to forget that radiation is invisible, can't be smelled, tasted, etc… Do you really think that fish have some extra-esp-ability or something that will keep them out of the area! How absurd. It has already been demonstrated that tuna migrate across the pacific and that many of them are already radiated. Like I said above, I think this is a teeny-tiny, yet positive step in the right direction. I'm not so sure about the dredging idea though. I don't think that will help and I do think it will do more harm — just like all the incinerating mess of spreading contamination. Best to leave the sea floor alone and alllow the particles to descend _even if terribly slow — unless maybe the future will present some type of rad-eating algae type solution. The only concern I have it that the netted are be larger, if possible or feasible.

      I never said the net was a bad idea…it's a fine idea and should have been put up on day one (or something better than a net). My statement was related to how it doesn't make sense that they want to keep fish from exiting the port. At the very least, why wouldn't they say they wanted to keep the fish from entering the port?

      Further, i'm not saying that fish have some extra ability to sense radiation, but I'm sure they know if there is a food source nearby. Of all the places along the coast of japan or in open waters where fish could find food, what do you think would be drawing them toward the port of daiichi? Remember, radioactive materials are not the only things in that water…the amount of toxic chemicals in that water must be astounding. You'd be a fool to think that the water is pristine except for radioactive materials. Again I reiterate, I doubt that there are many fish (if any) in that port.

      Further, the radioactive water is not isolated in the port, and never has been. Stopping fish from entering or exiting the port will not fix the problem of bio-accumulation. If you wanted to fix that problem, you'd have to net off most of the pacific ocean at this point.

      I support the net at the port, no doubt, but their reasons don't add up. How anyone could actually accept the idea that they want to keep the fish from leaving the port is beyond me. There must be another reason. I welcome your comments purp, but measure twice and cut once.

    Let us review…Tepco poured 785,000 square feet (10 football fields) of clay cement compound TWO FEET deep in the Daiichi lagoon earlier in 2012 (remember the frenetic videos of concrete mixer trucks running nonstop on the road to the plant?).


    SP: So now they want to net the lagoon and dredge the lagoon floor?

    In the classic comedic words of Eric Idle: "It's time to play the game of Spot the Loonies!"

    And the winner is: Enenews contributors for correctly spotting the Tepco and Diet naked apes in Japan!

    Once again Enenews commentators dissect the asinine actions of these loony surgical minds in Tokyo unveiling once again their tiny bandaids for the torso amputation of the writhing monster at Fukushima Daiichi.

    SP: Just when you think your opinion of the nucleocrats couldn't possibly get any lower…they unveil yet another scheme that puts them beneath the intelligence levels of Neanderthals. In fact I apologize to our ancient furry friends for the comparison. They never fouled their caves like the nucleocrats have perfected.

    ops, I've clicked wrong into this page.
    I was looking for info about Fukushima, not the SyFy site.

    • PhilipUpNorth PhilipUpNorth

      So, Andres, let's hear one or two of your ideas already. Welcome!

      • richard richard

        Andres is kinda right, a biiiiig net around fuku-d seems rather sigh-phi to me too.

        Most of tepco's disaster engineering, (I use that loosely) seems to come from fantasy.

        'I'm sorry Dave, I can't do that'.

    Lagoon Closed Loop Heat Sink:
    Interlocking steel cofferdam around lagoon, except shore side. Extend inland past Buildings1,2,3,&4 (and past underground corium beneath Buildings1,2,&3). Extend on inland side of Buildings1,2,3&4 to keep ground water out. Rectangular cofferdam now completely encloses underground corium. Add pipes and pumps to bring lagoon water to injection wells dug to depth of corium uphill from Buildings1,2,&3 inside cofferdam. Seawater will flow around corium, keeping the corium cool and stable, then flows back into the lagoon. You have now created a CLOSED LOOP HEAT SINK, maintaining water flow around underground corium, but limiting contamination of the Pacific Ocean, which is going to continue as long as heavily contaminated ground water is allowed to flow into the Lagoon and out into the Ocean. This project should have been completed in 2011. Better get your ass in gear, The destruction of the Pacific Ocean Fishery is on YOU!

      Right on! That is or seems like a workable plan, but… with additional earthquakes happening so frequently, it probably won't be any more feasible… it will probably just develop as many cracks and compromises as the plants themselves.

  • Sickputer

    They won't commit to spending a trillion dollars on cofferdams. It might have worked in the first six months of the Fukushima saga, but maybe too late now.

    The Japanese arrogant nucleocrats (cheap bastards) think in terms of incineration, giant nets, paving lagoons, covering reactor buildings with tent roofs, etc… Those are spoils system rewards for their business partners.

    Good idea from PuN, but also hinges on this: "Rectangular cofferdam now completely encloses underground corium".

    SP: Can any manmade fence corral the runaway coriums? How deep in the mudstone have they burrowed? The world wonders….

    But I am guessing top Japan, US, and possibly French nucleocrats already know exactly where the coriums are located. Their silence speaks volumes. It's an international coverup that one day will be unveiled, but it won't be today.

    • PhilipUpNorth PhilipUpNorth

      TEPCO isn't doing a lot of work these days at Fukushima, are they, Sickputer? Just mending pipes and hoses, fixing pumps, and keeping temprature and pressure guages working. Nets, tents, and incineration are all very bad ideas. the problem is not the fish, it's the radiation that would be flowing through the nets.

      It will take a trillion dollars to stop the Fukuplex from killing off Earth's biosphere, Sickputer. Japan or somebody has to step up to the plate pretty soon.

      Perhaps some cost cutting is possible, but only if begins to think BIG about Fuku. Here is one more idea:
      Build a Mobile Crane for removal of spent fuel assemblies from SFP1,2,3&4. Similar to the cranes shipyards use to lift boats:
      This crane would begin with SFP4, and could be moved to SFP1,2,&3.
      Come on, Japan. Think big, act fast. Fukushima is a monster eating you alive. Fukushima is not in cold shutdown!

      I thought that the net was intended as a small step to contain the radiated fish from escaping at large into the greater Pacific and also intended to keep them out of the local's diet — it's not about the radiation or the corium, it's about the food supply.
