Prof. Hiroaki Koide of Kyoto University: ‘Massive amounts of radioactive materials will be released into the environment again’ – Fukushima Reactor Core May Have Sunk Into The Ground – ‘We are now head to head with a situation that mankind has never faced before’

Radiation expert says outcome of nuke crisis hard to predict, warns of further dangers (Mainichi Japan, Sep. 9, 2011):

As a radiation metrology and nuclear safety expert at Kyoto University’s Research Reactor Institute, Hiroaki Koide has been critical of how the government and Tokyo Electric Power Co. (TEPCO) have handled the nuclear disaster at the Fukushima No. 1 nuclear plant. Below, he shares what he thinks may happen in the coming weeks, months and years.

The nuclear disaster is ongoing. Immediately after the crisis first began to unfold, I thought that we’d see a definitive outcome within a week. However, with radioactive materials yet to be contained, we’ve remained in the unsettling state of not knowing how things are going to turn out.

Without accurate information about what’s happening inside the reactors, there’s a need to consider various scenarios. At present, I believe that there is a possibility that massive amounts of radioactive materials will be released into the environment again.

At the No. 1 reactor, there’s a chance that melted fuel has burned through the bottom of the pressure vessel, the containment vessel and the floor of the reactor building, and has sunk into the ground. From there, radioactive materials may be seeping into the ocean and groundwater.

Possible Worst Case Scenario At Fukushima: A ‘MELT OUT’ (Even Worse Than A MELT TROUGH!)

For your information…

… but the project is in limbo because of opposition from TEPCO.

Preventing radiation contamination more important than TEPCO’s stock prices (Mainichi, June 20, 2011):

One figure who has entered the public spotlight in the wake of the nuclear crisis is 61-year-old

Hiroaki Koide, an assistant professor at the Kyoto University Research Reactor Institute and a controversialist in the anti-nuclear debate. A specialist in nuclear power, Koide has garnered attention as a persistent researcher who has sounded the alarm over the dangers of this form of energy without seeking fame.

In a TV Asahi program on June 16, Koide made the following comment:

“As far as I can tell from the announcements made by Tokyo Electric Power Co. (TEPCO), the nuclear fuel that has melted down inside reactors at the Fukushima nuclear plant has gone through the bottom of the containers, which are like pressure cookers, and is lying on the concrete foundations, sinking into the ground below. We have to install a barrier deep in the soil and build a subterranean dam as soon as possible to prevent groundwater contaminated with radioactive materials from leaking into the ocean.”

His comment captured public interest and when I asked a high-ranking government official about it, the official said that construction of an underground dam was indeed being prepared. But when I probed further, I found that the project was in limbo due to opposition from TEPCO.

A must-see:

A MUST-SEE!

Prof. Hiroaki Koide also measured radiation levels in Tokyo.

The Japanese government never admitted to this amount of contamination in Tokyo.

Prof. Hiroaki Koide concludes that if Tokyo has been contaminated this much, then ‘areas within Fukushima prefecture must be seriously contaminated’.

Hiroaki Koide: “Pressure Not To Release Radiation Data”:

In the testimony in the Japan’s Upper House Government Oversight Committee, Hiroaki Koide of Kyoto University said there was an outside pressure on him and his colleagues not to release the survey data including the radiation data on March 15.

He talks straight.

The committee hearing is still on-going. Access is still spotty.

Things Are Slowly Changing in Japan Over the Fukushima Crisis:

Hiroaki Koide of Kyoto University is testifying in the Upper House government oversight committee. The session is broadcast over the Internet, but the Upper House site is being overwhelmed with access requests.

Alongside Koide, Masashi Goto, whistleblower ex-Toshiba engineer who designed the containment vessel at Fukushima I Nuke Plant, Masayoshi Son of Softbank, geologist Katsuhiko Ishibashi are also there.

(Ishibashi insists on doing it (dealing with Fukushima I Nuke Plant) by the Japanese experts only.)

In the meantime, angry and concerned parents and citizens are swarming the Ministry of Education and demand that the government withdraw the 20 millisievert/year radiation (external only) limit for children. The Minister is hiding.

They are holding a meeting outside the Ministry. Each time some punk of a bureaucrat utters something, he is being shouted down by angry protesters, demanding the Ministry retract 20 millisievert/year.

“Why can’t you understand? What can’t you understand?” they are shouting at the bureaucrat.

I’m watching live on USTREAM.

Was Fukushima a China Syndrome? (TIME):

The China Syndrome refers to a scenario in which a molten nuclear reactor core could could fission its way through its containment vessel, melt through the basement of the power plant and down into the earth. While a molten reactor core wouldn’t burn “all the way through to China” it could enter the soil and water table and cause huge contamination in the crops and drinking water around the power plant. It’s a nightmare scenario,the stuff of movies. And it might just have happened at Fukushima.


- Hiroaki Koide of Kyoto University: “No One Knows How Fukushima Could Be Wound Down” As the Corium May Be Melting Through the Foundation:

So says Hiroaki Koide of Kyoto University Research Reactor Institute, in a telephone interview on May 19 with independent video-journalist Tetsuo Jinbo of Videonews.com (who did the video report of the 20-kilometer radius evacuation zone back in April, showing cows and dogs prowling the deserted towns).

Koide is practically agreeing with Christopher Busby that there’s not much anyone can do to stop the release of radioactive materials and further contamination of air, soil and water, other than somehow “entomb” the reactors (a.k.a. Chernobyl solution).

Koide reiterates his view that the corium (he says “melted fuel” and “melted core” in the interview for lay people, but it is melted fuel, and anything else that melted with the fuel inside the RPV) may have already escaped the Containment Vessel in the Reactor 1.

Following is my notes as I jotted down the salient points Koide made in the interview:
