I know we've probably covered this but why is R#3 so much more dangerous with it's plutomium?

well it's primarily heat. and all kinds of electromagnetic waves, including heat beams. and gamma rays. and xrays.

@Jojo I'm not Dean, but I could take a stab- the decay if isotope releases heat and atomic particles either bond with, or 'fall off of' other atoms to form new elements. As to the fission, by "tracking back the cat", They want to figure out where radioactive release is coming from, i.e. the fuel pool or the reactor. Dean...HELP!

OK elise... you can do some research.. the N reactor which was in richland washington DOE site was copied by the russians when they got the design , they build chernobyl to be like the N reactor with a graphite moderator and only thing... NONE of the safety features or containment...

it talked about the moderating being lessened in the duel

Now that I see "cherenkov" come up again, I'll try again to clarify something I asked over on Reuters. In this article en.wikipedia.org they speak of TWO types of blue glows associated with criticality accidents. One is cherenkov needing water/dielectric and the other does not. I am NOT saying we are seeing this type of blue glow, I was simply pointing out as it was discussed is that is seems there can be a blue glow associated with criticality incidents that does not need a dielectric.

@marie rich OK thanks. Has anyone (not TEPCO) made any progress as to where the fission is and how much energy is being released to result with the isotopes that they did? Clearly it's ongoing if they are getting 6-hour old isotopes?

hyperphysics.phy-astr.gsu.edu for you marie

Got it from an email I sent ~ You want a reactor to be "under moderated". That way if you lose moderation - the reactivity of the 
reactor will go down - as will the power. In the RBMK, it was "over moderated" - it had more than 
enough graphite moderator to do the job - and the excess actually interferes with the reaction. In such
a reactor, when the graphite heats up, and the effective moderation goes down - you are only getting 
rid of excess moderator - and reactivity goes UP, not down; and the power also goes UP.

good night all.. I must rest now... see you soon

@George: Thanks for putting all the links up.

@dyan : yep.

thanks dean.

NHK live pressure in 1 rising if I heard correctly

Correction I think they said temperature... tuned in kind of late

thanks

@ Marie A shutdown was a part of the test and inexperienced night operators were on duty, the test was scheduled for that day, which helped lead to the disaster at Chernobyl.

KGB? I dunno, the government did pressure them to do the test.

Another tsunami warning (lifted, thank God). Besides, the struggle to remove the water, has anything else happened? Thanks.

@Matsuoka Thanks for the info. Has anyone figured out what the implications of the fission reaction are based on the quantity of by-products? And how that bodes for the present and future for the reactor?

The half life of products will tell you the source. but with possible fission in the fuel pools, who can say? Looking for an expert opinion response here.
