Japan Earthquake

Japan Earthquake | Page 1005

I think @edano that they know so much about how fuku was overwhelmed and it has become obvious that the whole build of those reactors and housing are fatally flawed and cannot withstand anything.

sound like the beginning of a new aera. i hope so.
by Edano 5/6/2011 4:37:11 PM

They have so many npp's in Japan there must be othher mk1's there ? there really aren't any safe area's are there
by elainekirk 5/6/2011 4:37:33 PM

but why "hastily" if it is within 30 years ? are there predictions for a sooner quake ? it is quite surprising.
by Edano 5/6/2011 4:40:07 PM

don't tell me the 87% chance is something new. kan knew that before.

Hamaoka #5 is an advanced BWR, just went online in 2005. Taking the 3 reactors offline leaves another hole in available supply -- 4500 MW.
by Markfm 5/6/2011 4:41:48 PM

This may work per the bureaucratic definition of "hastily" -- in other words, a couple of years before anything actually shuts down, then the mothballing period commences.

So, I guess that decision by GoJ will finally (even a cat runs out of lives) end the "incident"-plagued Tokai Nuclear Fuel Works?

@bo you mentioned something about having a website with some related content? Maybe I read it wrong?

@Nancy my website is about my own academic work, which is about social and cultural issues related to preparations for nuclear war in the 50s and 60s, and also about hibakusha communities that were exposed to radiation from nuclear testing, not about Fukushima at all, but happy to post the website if you like

@Radioguy -- What decision effects Tokai?

@bo I thought it was referencing something for here. prob don't need it but sounds interesting. :-)
by Nancy 5/6/2011 4:56:56 PM

@Markfm If they're closing reactors in Tokai, for earthquake reasons, wouldn't that seem to extend to the reactor at Tokai? (They have one, don't they?)

After being relatively quiet in recent weeks in Iceland there now shaking the earth again reinforced. Swarm of earthquakes occurred in the Northeast today Askja. After all, there were four earthquakes beneath the glacier subglacial volcano Katla Myrdalsjökull with. These earthquakes are not to be regarded as direct signs of impending volcanic eruptions, but they are evidence of the tectonic and magmatic activity of the***Mid-Atlantic Ridge.***

(As if that wasn't confusing enough... the Tokai Fuel Works. I don't recall seeing it specified anywhere, but I've always assumed they must have a reactor on site for that work.)
by radioguy 5/6/2011 5:02:14 PM

@radioguy : no. tokai is a region west of tokyo, on the west coast, while tokai npp is located on the east coast north of tokyo. it's only the same name, but different regions.
by Edano 5/6/2011 5:02:26 PM

Location map of Japanese nuclear facilities calls out Tokai Works reprocessing facility on the East coast (but northeast of Tokyo, as opposed to Hamaoka being southwest of it): www2.jnes.go.jp
by Markfm 5/6/2011 5:07:12 PM

@radioguy : confusing enough, i looked it up in wikipedia:
1. Tokai region: south of Tokyo on east coast, pref. Chubu, NPP Hamaoka
2. Tokai city: north of Tokyo on east coast, pref. Ibaraki, NPP Tokai
by Edano 5/6/2011 5:09:13 PM

Totally confusing :). I'm pretty comfortable that JNES map is correct -- multiple references to the Tokai reprocessing works being in Ibaraki prefecture.
by Markfm 5/6/2011 5:10:42 PM

@elaine, if you run across something talking about the roof braces at Hamaoka can you let me know. There was a web page from Chubu talking about them and the retrofits and now I can't find that web page again.
by Nancy 5/6/2011 5:11:45 PM

So, closing Hamaoka wouldn't directly affect Tokai -- far apart geographically. If it represents a real GOJ change of heart, super, but I expect Hamaoka is a sacrificial lamb, bad siting even for Japan (which has few good choices).
by Markfm 5/6/2011 5:12:23 PM

@Markfm Oh well. That place has been closed since the 1999 disaster anyway. It was all completely decommissioned b6 2006. ;)
by radioguy 5/6/2011 5:13:27 PM

@Markfm : hamaoka once was the biggest plant worldwide. the name is a symbol for progress to the japanese.
by Edano 5/6/2011 5:15:07 PM

Look at the JNES map, though, and you'll see quite a few nuclear processing facilities, including along the coast to the southwest of Tokyo.

Ahh, from an AP article on the other page, the Hamaoka shutdown is temporary, until they can implement new safety systems (recent post by Veen) "Trade Minister Banri Kaieda said the utility company should halt operating its nuclear reactors while implementing such safety measures.

“Until the company completes safety steps, it is inevitable that it should stop operating nuclear reactors,” Kaieda said."
by markfm 5/6/2011 5:25:01 PM

@All Of the 5 fueled reactors and 7 storage pools which do you believe are the most likely to melt down and become diluted enough for the nuclear fire to go out?

by Bobby1 5/6/2011 5:34:11 PM

@DonnerT 5 and 6 supposedly have not suffered significant damage. R4 is toast. The building looks like it might be leaning, and the SFP has been compromised since the beginning. It's probaly a race between getting additional support under it and another big quake knocking it down.
