Sound Of Explosion Heard At Fukushima Daiichi Nuclear Plant -Kyodo, Dow Jones, May 31, 2011:

[T]he sound of an explosion was heard at the Fukushima Daiichi nuclear complex, but radiation levels haven’t increased and no injuries were reported, Kyodo News reported. […]

Tepco said it was possible that a machine ruptured a buried gas tank, causing the explosion, the report said.

  • Can anyone explain the presence of both nuclear winter in Cali, Oregon, and Washington, while there is a heatwave in the east and south east? The isotopes,…how may they effect things I mean.

  • Jeremie

    TEPCO says (likely) a remote machine touched a gaz cylinder while working to remove some stuff.

    Two arguments that show it’s a CRAPPY lie:

    – I was not looking at the cams at the time of the explosion, did you? I think it was pretty full of fog and rain (someone to confirm?), how would have it be possible to operate if you don’t see anything?

    – If it’s a remote machine, someone was remotely driving it. Thus, why speaking about “likely” explanation. The guy should have seen it, no?

  • Sandra

    There’s no nuclear winter! Look it up.

    If there were one, it wouldn’t be about radiation, just stuff blocking or reflecting sunlight. Climate change and variations is another subject. Don’t complain about CA being cool. When it gets hotter there will be the morning coastal fog much of the time. Things are nice now.

    Been at work.
    Did #4 (finally) blow up?
    If so, which way is the wind blowing?
    Towards North America?

    Thanks….

      Or Blow Down. Reactor #4 was the one severely leaning. Throw in a lot of rain, some wind, and some more fission and yes, the building go over/down anytime.

      • xdrfox

        I am thinking the crash that was heard was not equiptment but the spent fuel tank crashing to the ground in and outside of the plant ! Hope Not !!!

  • milk and cheese

    They have turned off the sound feed on the live camera.

    • SteveMT

      I hope “they” did and nothing else!
      What is more sensitive to radiation?: microphones or cameras?

      Just asking. I don’t know.

      What comes to mind are the telephone receivers melting in the movie: Fail Safe.

    Earth is currently in the grip of a minor technical anomaly. Scientists are checking their stock profiles and pertinent data to help resolve the ongoing catastrophic disaster.

    In the meantime, LATER crews are working round the clock to ensure that all non-radioactive personnel are kept in temporary shelters until slow termination by the state. Remember:

    TEPCO (Tokyo Electric Power Company) has reported an explosion at the crippled Fukushima Daiichi Nuclear Power Plant.

    There were no reported injuries or spikes in radioactivity around the plant.

    Dow Jones Newswires reports that,

    The explosion was heard around 0530 GMT as wreckage was being removed by remotely controlled heavy machinery on the southern side of the No. 4 reactor building.

    Tepco said it was possible that a machine ruptured a buried gas tank, causing the explosion, the report said.

    TEPCO gave the time of the explosion at ~05:30 GMT instead of providing the time in the local time zone. I can do that calculation, but how many people can actually take a time in GMT and convert it into a time in JST – it isn’t even the same day. But OK, it turns out to be about 2:30 in the afternoon if you believe TEPCO. I don’t.

    First, I doubt there is an underground fuel tank next to a nuclear reactor. Even if there were, ANY explosion would increase radiation levels because radioactive particles are all over the place. However, I have attached a photo of Reactor 4 in case someone can show me the location and type of the underground fuel tank. Conclusion: The statement is not true.

    Secondly, I doubt that people are operating remote-controlled heavy equipment without specific planned routes and copies of blueprints of the facility overlaid on maps in front of them with specific GPS coordinates FOR EXACTLY THE REASON THAT THEY DON’T DO SOMETHING LIKE THAT! Conclusion: The statement is not true.

    Third: The ‘live’ feeds have been off for longer than the time the indecent supposedly occurred. Yesterday it was supposedly because heavy ground fog obscured the area. People are not operating heavy tracked equipment around the Reactor 4 fuel pool in zero visibility – I was born at night but it wasn’t LAST night. Conclusion: Everything TEPCO says is molasses.

      You trailed off before the end of Burnett’s article, which read as follows- “What DID happen? We’ll have to wait for the picture to come back on but the most likely scenario is that the R4 fuel pool collapsed and the near-term clean-up effort has been set back to the year 2525.”

    Good morning from old Europe.
    I wonder if data for unit 4 has already all the time been missing on

    or if that’s a new phenomenon since last night, which obviously didn’t pass very convenient.
    Does anybody know??

  • Zardoz

    Good morning from old U.S. Yes, data for unit 4 has already all the time been missing from that array because unit 4 reactor has been nonfunctional due to scheduled maintenance operations.

  • Bread+Butter

    Zardoz,
    thank you. SO I can just happily go to work and live my little life, wondering why the sun still shines.

    Is it any wonder that I don’t bother reading the articles anymore just the comments! Thank you all so much for your endless pontifications they are precious to me!

  • oh boy ! too many posts in this thread. I can’t read all that.
    anyway, does someone know why some trees seems to have been cutted ?
    i look at the first webcam for a long time and since two days, some trees are missing. You can see that in the tepco webcam archive. Look at may the 27 an then the following days

  • Robot blamed for Fukushima nuclear plant explosion

    Tokyo Electric Power Co (Tepco) has blamed an explosion at Fukushima this week on a heavy machinery robot working on the stricken nuclear plant.

    Kyodo News reported that an explosion at 2.30pm on Tuesday was heard at the Fukushima Daiichi nuclear complex.

    Tepco said a remote controlled robot deployed on the southern side of the No. 4 reactor building to remove wreckage could have ruptured a gas tank under the plant.

    Tepco confirmed that radiation levels had not increased and there had been no injuries from the incident.
