Press Conference on Fukushima Daiichi Disaster
May 4, 2012 10:00 am ET

Speaker: Hiroaki Koide, Nuclear Reactor Specialist and Assistant Professor at Kyoto University Research Reactor Institute.

Rush Transcript Excerpt

Koide: The story is that Tepco is carrying out [UPDATE: Translation appears to be more like 'has carried out', not 'is carrying out'] reinforcement project to prevent spent fuel pool from falling apart.

However, the status of the work site is so contaminated that it is not a place where workers can work at ease.

I’m worried very much about how far they’ve been able to properly complete that construction.

I’m also praying that there wont be a number of large aftershocks.

Improved audio coming soon

    I'm also very much worried and would feel a hell of a lot better if they could dry cask the spent fuel at both reactor 3 and 4. Then get busy on the common spent fuel pool which I have read is cracked in a several places. The global community must attack this very dire situation.

    Build a ramp between this plant and the sea. That way if it collapses the whole thing can simply be bulldozed into the ocean.

    Gotham,……as sad as that sounds for the ocean,…it is a VERY, very good idea! It is dealing with what is,…period.

    how tall is one of the nuclear reactor assemblies in fuel pool 4

    how much does one weight

    if you were able to too can it be yanked out of its holder

    use a bucket in a bucket with trap door that can open fill with water and yank a assembly up into the round cylinder and then lift and put into a water cast to store it

      There is an issue of fuel rod assembly integrity. These are not pristine unused fuel rods of just uranium and plutonium oxide. They have gone through reactions that have left them with nuclides that are prone to go off with just a jostling.

      One of the early nuclear researchers died when he dropped a shielding brick on enriched uranium and started a reaction. Imagine the risk being multiplied with nuclides worse than plutonium and uranium with a frame that has sea water corrosion and I think that you will agree that although we need haste, we need caution that we wish that they would have had during the justification and design phases.

      A fuel rod is 4 metres long. The assemblies carry multiple fuel rods. The assemblies are longer than the fuel rods. They have a manipulating handle which enables a special crane hook to lift the assembly out of the pool/ reactor. The lifting process is all done while the assemblies are under water. There is a special "wet" bucket used to transfer assemblies in and out of the fuel pool.

      There is an in building 35 ton crane used for transferring the fuel assemblies.
      The fuel pools of these reactors are on the 4th and 5th floor. The in building cranes can no longer be used so an external crane must now be used to transfer the assemblies. The logistics of this operation are being carried out. The damage to all buildings plus the radiation levels will take a while to be assessed.

      On going seismic activity makes this operation risky. Imagine the scenario of trying to operate a 150+ foot boom crane lifting a critical fuel rod assembly and a mag 5+ earthquake struck at the same time.

    Is this some kind of joke?

    The audio I received was so poor it was all but unusable. Key words in English were dropped out.

    I don't understand. Was it posted like that? If so why was it left up for so long?

    Was the server or the disseminating routes of broadcast hacked? Then post it, please.

    Is it my computer or networks in Canada?

    Just had my 'Canadian Broadcasting Corporation' website member profile page suspended moments after writing a comment about the Canadian Embassy moving it's 'visa for Japanese citizens department' moved from Tokyo, Japan to Manila, Republic of Philippines.

    So I'm not use if the interference is on your end or in our end.

    Anybody?

    See "Improved audio coming soon" above video. Yeah, that is as bad as it gets without being pure garbage. Used a mobile phone on the wrong setting to record off the speaker of another phone. Hopefully PSR or another will post the full event soon. If anyone finds it, please send in or post a link.

    Thanks for the quick response, ENENews, was getting even more paranoid than usual.

    Deep breath. Exhale completely.

    the very last thing you want is the nuclear reactor specialist invoking superstition to control his offspring as in "pray for.' may i invoke some foul language? #$#$%,,$%@%TR%^$,,,#%$R%^%$%^T%$%&^%E!!!!!!

      Wrong specialist. He has been warning the danger of nuclear power plants for decades along the lines of Gundersen. Knowing is one thing and how to act based on the knowledge is just another.

      "Hiroaki Koide, Nuclear Reactor Specialist and Assistant Professor at Kyoto University Research Reactor Institute. After realizing in 1970 that nuclear power was extremely dangerous, Mr. Koide dedicated over 40 years of his career to educate the nuclear industry and the general public to stop nuclear reactors in Japan. After the nuclear disaster in Fukushima, he gained “rock star” status due to his tireless efforts in providing detailed analysis and honest suggestions to the Japanese community about the extent of the disaster. He will speak about the extremely dangerous conditions at the Fukushima Daiichi Nuclear Power Plant, including the concerns regarding the damaged Unit 4 irradiated fuel pool."(http://cinemaforumfukushima.org/2012/05/04/cff-2nd-ustream-is-may-4th-fri-10am11am-jpn-55-2324/)
