Kyoto U. nuclear professor: Much more serious than I envisioned — We’re in uncharted territory for first time ever since humans started using nuclear power (VIDEO)

Description: Dr. Akira Hiroshi Koide (Research Reactor Institute, Kyoto University Professor), VideoNews, May 19, 2011:

Following is my notes as I jotted down the salient points Koide made in the interview:
[...] I believe the Reactor Pressure Vessel has a large hole, not the small holes that TEPCO says. [...] much water has leaked (4,000 tons in the reactor building basement) and yet TEPCO says there’s still pressure inside the RPV. It is impossible, given the structure of the reactor.
We’re in the uncharted territory that we enter for the first time ever since the human race started to use nuclear power. [...]
The Suppression Chamber in the reactor building basement is torus-shaped. The location where the corium may have dropped is the center of the torus, and it is concrete. The thing to worry about is how far down the concrete the corium will go.
The water circulation system using water in the building proposed by TEPCO is tantamount to admitting that the Containment Vessel is broken. It is a much more serious situation than I envisioned, [...]
However, if the corium goes into the concrete, no point in talking about circulating water to cool. There will be nothing you can do. The only way may be to entomb the whole building in a concrete coffin. [...]
There is a possibility of further hydrogen explosion, and it is still possible that Fukushima exceeds Chernobyl in terms of magnitude of the disaster.
