@Edano the manual talks about beyond design basis that involve a critical pipe break LOCA or a station blackout plus LOCA. They pretty much say the Mark 1 BWR is doomed due to design flaws. This is without adding in tsunamis, sea water injection and 9.0 earthquakes. It does talk about the standard event scenarios putting connections into the RPV and containment at risk just due to heat etc.

@Peter you should be in luck they do like their transcripts
www.google.co.ukby elainekirk 9/21/2011 11:40:24 PM

@Peter if that is the one being held in Virginia it is a teleconference and Dean said he can order a transcript after the meeting.

@artnuke how do you want to tell if a cancer is caused by cesium ?
by Edano 9/21/2011 11:56:45 PM

would it be an idea if we keep this page technical and move debate to organise it isn't really working having two conversations going ??
by elainekirk 9/21/2011 11:59:25 PM

smoking causes cancer as well.
by Edano 9/22/2011 12:01:20 AM

what needs to happen is that people are given facts , not supposition , not scare stories, not 'smile and you will be saved' but facts .
by elainekirk 9/22/2011 12:05:37 AM

@artnuke stronium, plutonium etc. there are lots of other things being found in Japan that cause cancer.

I am counting 5 cranes around #1??
by elainekirk 9/22/2011 12:25:28 AM

back and hello to all
by dean 9/22/2011 12:27:51 AM

@elainekirk tepco or tbs?
by lillymunster 9/22/2011 12:32:27 AM

tbs
by elainekirk 9/22/2011 12:32:59 AM

NUCLEAR DATA
FOR THE CALCULATION OF
THERMAL REACTOR REACTIVITY COEFFICIENTwww-nds.iaea.orgWow this will keep the number crunchers here busy
by elainekirk 9/22/2011 12:33:47 AM

@elainekirk I see it. Moved all of them over there and TEPCO cam is down. Wonder if something happened.
@Dean Hi!
by lillymunster 9/22/2011 12:34:33 AM

looks like a big erector set of cranes..
by dean 9/22/2011 12:35:20 AM

@ elaine and @ lilly.. hows the BWR simulator training coming.. :)
by dean 9/22/2011 12:36:16 AM

@lillymunster I would say so, rockhopper says all is calm and has been for a good few hrs I think the cam is turned off rather than faulty
by elainekirk 9/22/2011 12:36:22 AM

@elainekirk The cranes don't seem to be doing anything.
@Dean, haven't started on it, still finishing the BWR document in between a few things. I will probably be ready to run my first plant tomorrow. :-)
by lillymunster 9/22/2011 12:39:27 AM

@dean I tell you I am already certifiable :)
by elainekirk 9/22/2011 12:41:06 AM

interesting physics paper @elaine
by dean 9/22/2011 12:41:37 AM

lol @ lilly and elaine
by dean 9/22/2011 12:41:50 AM

@lilly and @elaine.. maybe tomorrow or the next day we can have our first nuclear physics basics for reactors... the 6 FACTOR formula is the standard for describing what goes on in a reactor core...
by dean 9/22/2011 12:42:53 AM

i guess the steel construction collapsed.
by Edano 9/22/2011 12:43:03 AM

the 6 factor formula is the neutron life cycle balance equation
by dean 9/22/2011 12:44:01 AM

@ Edano do you think it did for real?
by dean 9/22/2011 12:44:13 AM

The "Six-factor formula" is the neutron life-cycle balance equation, which includes six separate factors, the product of which is equal to the ratio of the number of neutrons in any generation to that of the previous one; this parameter is called the effective multiplication factor (k), a.k.a. Keff. k = LfρLthfηЄ, where Lf = "fast non-leakage factor"; ρ = "resonance escape probability"; Lth = "thermal non-leakage factor"; f = "thermal fuel utilization factor"; η = "reproduction factor"; Є = "fast-fission factor".
k = (Neutrons produced in one generation)/(Neutrons produced in the previous generation) When the reactor is critical, k = 1. When the reactor is subcritical, k < 1. When the reactor is supercritical, k > 1.
by dean 9/22/2011 12:45:23 AM

@dean there was a quake about the time the teppy cam first went down my money is on the ground under the construction moving
by elainekirk 9/22/2011 12:45:41 AM

one waving panel could possibly destroy the balance.
by Edano 9/22/2011 12:45:51 AM

@dean you just totally lost me but have you seen the doc I posted re reactivity(recriticality) lots of lovely numbers in there for you
by elainekirk 9/22/2011 12:46:47 AM

true Edano.. if they had one or partial panels up they act as huge sails and with the wind force acting over that square footage it just may be enough to topple it
by dean 9/22/2011 12:46:54 AM

@ elaine.. all those numbers makes my head hurt whewwwwww... that class was a long time ago....
by dean 9/22/2011 12:47:43 AM

the paper, among other things talked of the temperature coeffecient for reactivity... reactors generally have either a positive temp coefficient or negative so when the temp is increased reactor power will go up.. or down
