Triple disaster proves need for an industrial revolution
search.japantimes.co.jp
"Our industrial civilization should be aimed at promoting the recycling of resources, an orientation toward nature, public safety and the enrichment of human values.
With this in mind, we Japanese should work hard to overcome our current national crisis and pave the way for a new industrial revolution. In this way we will respond to the expectations of the international community"

@Veenie , the NYT published an article with a similar tenor last week in which they portray this guy as an anti-establishment figure who does not trust the traditional gov. zions. The authors of the article explained the discoordination of the gov. response to the crisis with the antagonism between his team and career administrators who are supposedly allied with the industry.

@bojack54 Yes, they do love to water their plants under cover of darkness. They would not want the people to see all that steam and smoke in their sky during the day.

@Peter Melzer Well, this article "I did not see the prior one" shows a huge disconnect between the caring but helpless vision i had with GoJ and TEPCO.......this here, once and for all proves, that the GoJ is the primary backer and cover up + funding source for the JPN Nuke industry.

@Reed , in my reading this observation goes to show that the filters are quite effective. They totally underestimated how radioactive the water actually is. It means that they need improved shielding for the filters, that filtration must be enlarged, and they must ponder what to do with a mountain of highly radioactive filters.
by Peter Melzer 6/18/2011 1:06:39 PM

@Veenie , here is the article with the title "In Fukushima Nuclear Plant Crisis Crippling Mistrust" published last Monday: www.nytimes.com . They say Kan sprang from a anti-gov. grass roots movement. I am only repeating!
by Peter Melzer 6/18/2011 1:11:20 PM

@Peter Melzer Thanks, reading it now.
by Veenie 6/18/2011 1:12:29 PM

Morning! Has TEPCO made any statements what plan b with the water filter system is?
by lillymunster 6/18/2011 1:15:19 PM

@Peter Melzer Yes, it seems to be a very good sign that the filters are so effective ! Let us hope that they have a massive supply of them, and that they can continue the process as soon as possible.
by Reed 6/18/2011 1:15:34 PM

@Reed , on second thought, since it is only one filter that reached the limit, it could be that some highly radioactive particulate lump got stuck in this filter. When you measure the radiation dose in samples, such lumps may escape.

good morning to all

TEPCO suspends water decontamination system

Tokyo Electric Power Company has halted operation of a system to decontaminate highly radioactive water at the Fukushima Daiichi nuclear plant as one of the parts reached its radiation exposure limit in less than 5 hours.

The system went into service on Friday night.

One component of the system uses the mineral zeolite to absorb radioactive cesium. A replacement part of the US-made device had been expected to last one month, but radiation exceeding the maximum 4 millisieverts per hour led to the dramatically shortened lifespan.

TEPCO suspended operation of the device early on Saturday to determine the cause.

The utility says it has so far found no abnormalities with the system or water leakage in the system. It adds that the device's dosimeter may have detected radiation from nearby pipes containing contaminated water or other radioactive materials.

The treatment system holds the key to halting the accumulation of highly radioactive water and re-circulating contaminated water to cool the reactors.

somehow this all sounds utterly stupid.
by Edano 6/18/2011 1:23:10 PM

Morning Dean!
@Edano, I hope by that article maybe they had an odd reading. I don't know enough about corium and rod properties, how much of that material can break apart or be suspended in water? Maybe suspended very radioactive concrete dust in the water making the levels sky high?
by lillymunster 6/18/2011 1:25:58 PM

Good view of a strato steam now on cams at Daiichi.
by estacion 6/18/2011 1:27:20 PM

the zeolithe (spongebob) is full. in 5 hours, but they expected it to be full in 1 month. the magic has gone. :(
by Edano 6/18/2011 1:28:13 PM

i hope they have a return right for the mashine.
by Edano 6/18/2011 1:29:29 PM

@Edano If they test the water at the surface but pump it out from the bottom that could explain the drastic difference than expected. Think cleaning an aquarium, everything settles to the bottom.
by lillymunster 6/18/2011 1:29:55 PM

@Edano Postal service will be there tomorrow to ship it back for a refund. :-)
by lillymunster 6/18/2011 1:30:25 PM

tepco is a madhouse.
by Edano 6/18/2011 1:31:52 PM

@Edano There must be 148 times as much radiation in the water as they thought. Are they trying to soak up multiple Chernobyls with zeolite?
by Bobby1 6/18/2011 1:32:13 PM

@Bobby1 :) somehow i expected it, but not that fast :)
by Edano 6/18/2011 1:32:52 PM

I wish I had a schematic of that clean up system.. would be nice to see where the alarm sensors are located, and if the sensors are collimated ie: shielded from background levels..
by dean 6/18/2011 1:34:09 PM

@dean : kurion is a superduper hitech company, i would expect they thought about that, no ?
by Edano 6/18/2011 1:36:40 PM

@dean all I have found is pictures and basic drawings without details in news articles.
by lillymunster 6/18/2011 1:36:45 PM

Good morning all. Any "good" news today?
by Shadow 6/18/2011 1:37:36 PM

I read that about kurion but they are only one segment of the whole operation and who ever knows how their help may have been modified.. remains to be seen
by dean 6/18/2011 1:37:45 PM

I thought the kurion portion had some new super duper filtration media in it other than the zeolite. If this is the first time they have made a system, ie: selling vaporware they could have made a mistake about the sensors.
by lillymunster 6/18/2011 1:39:47 PM

@dean : let's blame the workers. it was a handling error.
by Edano 6/18/2011 1:40:42 PM

operator error.. TEPCO gave right orders... duh..
by dean 6/18/2011 1:41:21 PM

@lillymunster : one day (you remember ?) i tried to read between the lines of the kurion presentation, and i came to the conclusion that they use nothing else but zeolithe, the only invention was, that they "vitrificated" the powder.
by Edano 6/18/2011 1:42:42 PM

I agree Edano.. you go back to TMI and try to find KURION name.. I couldn't
by dean 6/18/2011 1:44:01 PM

@dean : no. they just say they "advanced" the media used in tmi. in tmi they used resin, kurion uses minerals = anorganic = zeolithe media. this is all the magic.
by Edano 6/18/2011 1:45:31 PM

yes.. Edano.. I can imagine companies that had a small part of TMI now saying their systems were instrumental to TMI to get the job on FUKU
by dean 6/18/2011 1:46:38 PM

Kurion was so vague about what it is. So it is some sort of zeolite formed pattie, sheet or possibly they make a pellet with more air holes for better contact with the water...
by lillymunster 6/18/2011 1:48:02 PM

@dean : i guess they prefer to stay silent. the radiation in fuku is simply too high.
by Edano 6/18/2011 1:48:16 PM

@Edano: TMI=bicycle Fuku=20 ton garbage truck.
@Dean: IIRC one of the people involved with Kurion worked on the TMI clean up.
by lillymunster 6/18/2011 1:49:31 PM

@lillymunster : i think i saw it in some video. it's a powder.
by Edano edited by Edano 6/18/2011 1:49:45 PM

Tepco has been chronically underestimating radiation figures across the board since this started, I am not surprised if the contamination amounts are much worse than they said. Of course, this screws up Kurion and any other entity depending on their figures.
by Bobby1 6/18/2011 1:50:37 PM

they need some system that will be able to cartride load the filters etc.. remotely and have then flop in a shielded cask.. I anticipate this is only the beginning with problems on cleanup.. tip of the ice berg kind of thing
by dean 6/18/2011 1:51:46 PM

Let us hope that they can fix the filter issue soon, because the water is rising...

by Reed 6/18/2011 1:52:39 PM

i think we have to face the fact that there is nothing to hold it back. not that this is a new thought....
by Edano 6/18/2011 1:54:02 PM

@dean , dean I hoped the interconnected green containers they showed us in the pics were shielded, and that you just had to switch out the container once the filter is at capacity.
