Thank you very much for the update and the kind words. Still lurking after all this time...

some more detail here. http://www.24heures.ch/monde/europe/accident-nucleaire-sudest-ukraine/story/12186992 apparently some sort of fire in the "electricity output section" whatever the heck that means. One of the six reactors is in a state of shutdown.

What do we know about the Cs contents of the unit 4 SFP?

Yes, but the mean free path of alphas is way longer. I think the original thread has links to some open-source Russian papers that I dug up specifically to table the issue, but I don't really have the time to dig for them right now. I might later...

No it doesn't. You can have steam bubbles around the fuel elements without the pool even being close to boiling yet.

Very disappointing. They continue to misunderestimate radiolysis as a source of hydrogen for the unit 4 explosion, there is absolutely no discussion of steam radiolysys at all, no discussion of the temperature of water in SFP4, absolutely no discussion of reflected shockwaves as a mechanism for...

Anything on the effects of the recent storm?

I did NOT expect it to look exactly like those carnival machines with the stuffed toys inside.

I am not sure the gamma detectors they had were all THAT sensitive/discriminating. Too, one does not exclude the other.

I would like to see the reasoning behind this. Also, I don't recall anyone claiming that sustained nuclear fission was taking place at that time. That seems an odd thing to disprove - what might need disproving is the claim that there were short fission bursts taking place because of the core...

Don't think I've seen it before. Thanks.

Thank you for the update. I wonder why they put up the tent in the first place.

That beam which is featured in both pictures is cracked in the middle. I guess it's a good thing they cleared the debris above it so (relatively) fast.

Under the keiretsu system, sub-sub-sub-sub-contractors end up doing most of the grunt-work; they do it for very little money and with very little oversight. Big-ticket items get handled by the big fish directly, and they actually pay people, train them and care about their corporate reputation.
