Interesting report on the quality control of the MOX at Fukushima. www.klimaatkeuze.nl

@smoss Hi, not sure if you already read the article I posted. They knew some of the mox at fuku was bad but still apparently ran it?
by lillymunster 6/27/2011 2:43:55 AM

@lillymunster Just read it...wonder if Dr. Hideyuki Koyama's analysis was published and if he has made any more recent comments (Still wondering if they actually loaded the 32 FAs shipped in 1999, or manipulated their accountiing of fissile material and loaded a different set of MOX FAs)

@lilly.. I traveled to work this afternoon.. whewwwwwww 3 hour drive ,,, I wondered if you were able to get that to PETER
by dean 6/27/2011 2:49:37 AM

@dean Yes. I emailed it to him this afternoon. I forwarded the email so he should be able to contact you back directly.

@Dean, YW. Not sure if you caught it yet. They popped the water berm at Ft. Calhoun with some heavy equipment.

@all The court ordered TEPCO to either produce the data demanded by the plaintiffs or give a sound argument on why they cannot provide the information. The court ordered TEPCO to give specific details on the following points: (1) how and what they confirmed during the witness inspection, (2) the contents of the pre-manufacture process confirmation, (3) the precision of the laser micro-meter used to measure pellets for the total pellet inspection, (4) the average and standard deviation figures for the total pellet inspection if it exists. (TEPCO maintains that there is no data from the total pellet inspection.)

now see.,. that probably wasn't in the PRA for an identified initiating event
by dean 6/27/2011 2:56:10 AM

@dean It didn't seem to kick off any upgraded alert. They are being vague about the 1004 sea level of the plant vs. the 1006 ft. water. So unsure where the water actually is on the main building.
by lillymunster 6/27/2011 2:57:29 AM

TY lilly for the update.. any new news on cooper ..
by dean 6/27/2011 2:58:32 AM

@smoss I keep stumbling across these things trying to find some data on the Kashiwazaki MOX inventory or inspections. Every time I find something it is just more of this puzzling lack of safety processes.
by lillymunster 6/27/2011 2:59:32 AM

@dean Nothing new that I found. Cooper should see a 1.5 foot increase in the next week. (Calhoun water to stay the same). That puts Cooper over the line for being at an alert but below their flood protection tactics. So we could see Cooper forced into shut down this week if the water increases per the predictions I found.

lilly.. I did a search on 'QUALITY CONTROL ON MOX PELLETS. and it opened up a whole big long story of problems
by dean 6/27/2011 3:02:12 AM

@dean If it is anything like the few papers I ran across so far it does not seem to be good. One claimed the license and ISO rating one of the manufacturers had amounted to nothing as far as any actual proof of quality or competence.

2 feet if water us around the containment and axillary buildings at Ft. Calhoun. www.msnbc.msn.com
by lillymunster 6/27/2011 3:10:25 AM

@lilly.. I'm not positive but from what I've done on the MOX it's one international agreed upon way to get rid of the plutonium left over from the cold war to prevent it from getting into the wrong hands.. on the surface perhaps a viable reason.. however, from that point is where it breaks down .. multiple countries and companies trying to get the work and with little international regulations all kinds of "what ever it takes to get the product out' attitudes that , as you know, finally come to the surface...I say.. stop mox and go to plan B.. and run the fuel in the reactors they were originally designed for..
by dean 6/27/2011 3:11:29 AM

A berm holding the flooded Missouri River back from a Nebraska nuclear power station collapsed early Sunday, but federal regulators said there was no danger. COUGH COUGH COUGH.. what the heck are they thinking
by dean 6/27/2011 3:12:32 AM

@dean They forgot they mentioned early on that they had this awesome water berm so everything was going to be fine.
by lillymunster 6/27/2011 3:13:30 AM

I'm going to get some letters off to the senators (3 of them) that are calling for a special hearing with the NRC..
by dean 6/27/2011 3:13:31 AM

next.. water berm has failed and buildings full of water but it's no danger because the reactor is shutdown safely .... sigh
by dean 6/27/2011 3:14:13 AM

@dean Nebraska seems to be a bit defiant about the risks with the situation. They seem to forget they placed these near 3 other states..

I don't know how they are going to effectively keep water out through August. They claim they have other prevention to keep water out but don't give details. I worry about frying electrical systems.
by lillymunster 6/27/2011 3:15:57 AM

I think they said the doors were water proof or something,,, but you know.. water finds it's way down,,, the one thing I want to know is how about all those other buildings outside the berm? are they part of the secondary system ,, storage or waste treatment, air compressors etc.?
by dean 6/27/2011 3:17:43 AM

Hi all! @Lilly @dean As in Fuku won't they also have to deal with corrosion issues. How old are Calhoun and Cooper?
by LM 6/27/2011 3:18:09 AM

@LM 60's/70's. Cooper is an old Mark 1 BWR.
by lillymunster 6/27/2011 3:23:04 AM

@dean Am I mistaken in assuming that the water fed into a reactor and SFP has to be completely clean? That would make the Missouri a problem?
by LM 6/27/2011 3:24:30 AM

correct LM .. if that missouri water entered .. the reactor may be TOAST
by dean 6/27/2011 3:26:19 AM

@Lilly When are they ever going to learn that running old equipment is even more dangerous than running an already dangerous technology!
by LM 6/27/2011 3:27:22 AM

@LM Missouri river water is pretty gross on a good day. It would wreck anything it gets into.
by lillymunster 6/27/2011 3:27:25 AM

@dean @Lilly Wow...they really are trying to keep things on the down low. This would get a lot more press if the average person knew what as at stake.
by LM 6/27/2011 3:29:26 AM

IF that water entered the SFP they would have to flush and flush and hope they could salvage the fuel...if in the reactor it could be weeks if at all to salvage it and get the chemistry control back..

by dean 6/27/2011 3:30:07 AM

Thanks lilly and dean! This all just goes to show that it's not just the Japanese. The entire industry needs a complete overhaul.
by LM 6/27/2011 3:32:17 AM

@LM What caught my attention before the flooding started was that Ft. Calhoun was on the NRC yellow "naughty" list for unsafe procedures. Their flood plan in 2010 had major gaps in it and they found holes in the building that were not taken into consideration.

We don't have much room to toss stones at Japanese oversight. Our own is certainly lacking in some areas.
