Updated roadmap no longer mentions how holes in reactors will be plugged — Kyoto prof perplexed this “most important” point was left out

Plugging reactors no longer stated goal for Tepco, Japan Times, July 20, 2011:

[...] To substantially reduce the amount of radioactive materials released from the plant, Tepco needs to get to the bottom of the problem: plugging holes or cracks in the reactors’ containment vessels that are allowing contaminated water to flood on-site facilities, including the reactor buildings and turbine buildings, experts said.

The updated road map, however, includes no reference to this critical work in the second stage, even though it was mentioned in past plans. And without fixing this problem, it is difficult to say that the release of radioactive materials is under control. [...]

Tsuyoshi Misawa, a professor of reactor physics at Kyoto University’s Research Reactor Institute:

  • “In terms of managing the leakage of radioactive materials, I think plugging the holes will be the most important point.”
  • Misawa was perplexed it wasn’t included in the new plan.

Hisashi Ninokata, a professor of reactor engineering at Tokyo Institute of Technology:

  • “It seems unclear what kind of plans they are considering.”
  • Ninokata stressed the importance of plugging the leaks in the containment vessels.

“While plugging the holes is vital, Misawa and Ninokata acknowledged it will be difficult because the radiation level is dangerously high near the reactors, making it hard to work at the site,” the article added.

    tepco trying to pull the veil over the people, but the people don’t allow them to this time around.

    Have I been reading an alternative dimension news feed? Melt-through? (pinches self – ouch).

    So ok what’s the plan now? Plug the holes, insert new fuel and start ‘em up again?

    This is like turning of the light switch to a light bulb that has exploded all over the floor and claiming you turned out the light.

    Tepco flunkies: ” While plugging the holes is vital, Misawa and Ninokata acknowledged it will be difficult because the radiation level is dangerously high near the reactors, making it hard to work at the site.”

    Well, yes I would say it is vital. In fact if they don’t try suicidal efforts to plug the holes then they might as well admit Japan is going to become a hotbed of radiation and possibly a dead zone for the entire island. The effects on other countries eventually may well be the same. There is a tremendous amount of invisible killing power left to be dispersed. The recent lies of “stability” just show why Tepco is absolutely an insane company. Lunatics running the cleanup!

    What holes? It melted through and below. Screw the holes – we have the corium below the containment. Yes – I begin to get the feeling I landed on alternate dimension, and experience the cognitive dissonance. The same feeling when I read business/political news.

    Holes in the building. They are still flooding the basement and so I assume the nuclear blob is not through the concrete because of those flooding efforts. But feed and bleed probably is not a longterm remedy for the damaged building unless they can control the rate of water both ways.

      “While plugging the holes is vital, Misawa and Ninokata acknowledged it will be difficult because the radiation level is dangerously high near the reactors, making it hard to work at the site,” the article added.”
      err so they want thousands of high pressure welders to weld the holes , huh? maybe solder would be quicker? question where exactly are these “holes” are they metal or concrete or both? are they in the basement or on the ground floor? where exactly is the corium, let me guess that some of it is near the….hole, mixed with it if you like? hmmm so what are they going to plug it with? that wont degrade to dust in short order?
      and this
      “It seems unclear what kind of plans they are considering.”
      let me guess….plans to mitigate loses and retire quickly to the southern hemisphere, maybe australia? best sell those stocks too and buy gold,,drible dribble……..all views and opinions of this blogger are his own personal rantings and are not describing anyone living or dead, cos i must be dreaming! /surreal moment!

    What is there to be ‘perplexed’ about? This is magical thinking. If you don’t mention the holes in the building, the people will forget about them. Maybe the holes won’t even exist any more. TEPCO only spoke the truth when they refused to deal quickly with the disaster because it would have cost them too much. TEPCO hire expendable people to go into the reactors, give them inadequate training and protection, and then let them die. It’s not a matter for perplexity. Why, their motives have always been clear: money.
    The fact that the Japanese government, and this company, are still allowed to remain in power is pretty disgusting.

    I feel like I’m in the same alternate dimension. Are they talking about patching the holes and cracks in the concrete? It sounds like they’re referring to the RPV’s but why shut the door after the horses have left the barn?

    I assume they’re pumping water into the reactors hoping that some of it is washing over the corium wherever it is. And that water flows out of the cracks in the buildings and probably makes its way to the ocean.

    It seems to me that Tepco has moved from lies and magical thinking to psychotic babble.
