--- snip
This is from the transcript of the interview (in Japanese, NOT the literal translation) Koide gave on April 5, 2011 on Osaka's MBS Mainichi Broadcasting Radio:

"The Fukushima I Nuke Plant accident is not winding down at all. I think I have to revise my opinion which was too optimistic."

- What was too optimistic?

"We thought the reactors "cold stopped", which means the uranium fission stopped. But now I've started to think the fission has started again. In other words, the reactor has become "critical" again - which we call "recriticality"."

- Professor Koide, you were of the opinion that the recriticality was not happening.

"Yes, and I've changed my mind. It may be happening."

1. Hey, if the reactor can change it's mind, so can the Professor
Too many opinions and not enough facts.

3. No one knows since the instruments don't work, too much room for speculation

And Reuters' writers are clueless

WASHINGTON (Reuters) - A top official from the U.S. Nuclear Regulatory Commission said on Wednesday it was not clear that Japan's Fukushima No. 2 nuclear reactor has melted through the reactor pressure vessel.

Earlier, Democratic lawmaker Edward Markey told a House of Representatives hearing on the nuclear disaster that the NRC had told him the core had melted through the vessel.

"That's not clear to us, nor is it clear to us that the reactor has penetrated the vessel," said Martin Virgilio, deputy executive director for reactor and preparedness programs at the NRC.

2. Other countries are shutting NRs down- not us.
The unmitigated GREED of a few
continues to endanger the entire planet.

5. It seems that Professor Koide is on board with Gunderson's analysis from a few days ago.
