Co-chair of Russia’s Ecodefence and others “still fear criticality” at Fukushima — “I don’t think there is a reason to say situation has improved much actually”

Chain reaction scare at Fukushima only fission incident, say authorities, but environmentalists still fear criticality, Bellona, Nov. 9, 2011:

“Nuclear physicist Katsutada Aoki […] criticized TEPCO, saying the utility could have done a better job analyzing the implications of the newly discovered xenon gases and avoided spreading needless fear that a nuclear chain reaction might have restarted.”

“In a confusing and worrying announcement, TEPCO revealed last Wednesday […] the melted fuel in the reactor could have briefly reached criticality since xenon can be generated through such nuclear fission.”

“But one day after the announcement, TEPCO denied criticality had occurred, saying it found the amount of xenon was too small to be generated through fission via criticality.” […]

“An uncontrolled chain reaction occurring in the bowels of one of Fukushima Daiichi’s wrecked reactors could lead to an explosion and yet further spread of radioactivity.”

Experts discuss Criticality

  • Aoki said that “the chances of criticality taking place is not zero.”
  • Vladimir Slivyak, co-chair of Russia’s Ecodefence said “I don’t think there is a reason to say situation (with a possible chain reaction) has improved much actually.”
  • “We see the possibility of chain reaction is still there and no one can actually guarantee that no problems will again occur at Fukushima.”

    Thank you, Jesus – we get a refreshing breath of honesty from who? The Russians.

      Hi radegan…..
      I find that RTtv(Russian tv in english)is a much better news orgs than anything that passes for news based here in the US. Our media is just a mouthpiece for consolidation and retention of corporate power. Shit, Al Jazeera is twice the news org than anything we’ve got! More truth, less propaganda.

    The Russians know that the entire half of the continent could become covered in radiation from Fukushima FINALLY???!!! Well at least one nation knows the situations is dire. It only took them 8 months to realize their own hides are at stake too.

  • Very scaring – another earth quake can trigger such a disaster ?

  • Edward Edward

    Where is Anderson Cooper and CNN??? They were in Japan when these meltdowns first happened, then ran away never to speak of it again. This nuclear nightmare did not go away, but the U.S. media and government sure did stop covering it. We are very disappointed.

      >Where is Anderson Cooper and CNN

      SP: Also his buddy the doc…Sanjay Gupta. When they quickly left on the jet plane they went right through the plutonium plume from the Reactor 3 explosion… a plume estimated the size of Texas…quarter of a million square miles. Bad timing. I bet they won’t be back in their or our lifetimes.

    I wonder what the Russians will do about this? It is obvious that the USA isnt going to do anything other than to go into that great night with a whimper but I see the Russians raging against the dying of the light and refusing the happy talk of the USA. Without Us the corporations are going down because they do not own the world without US military might and with the taxpayers dying of cancer and no one to draft, there go the corporations. No way to kill off or bribe off those around the world who object to corporate dominance.
