According to this page nuctrans.org Reactor #4 was designed and built by Hitachi.

@myself correction, all were built by Kajima, 4 was designed by Hitachi....

The Fukushima nuclear reactor suppliers were 1) GE, 2) GE, 3) Toshiba, 4) Hitachi, 5) Toshiba, and 6) GE. en.wikipedia.org

So where is toshiba coming from ?? it isnt important.... it just seemed odd ...I wasnt even looking for it ...it appeared in a search and....should I shut up and put the kettle on?

@elainekirk Page 5 in this presentation - Toshiba claims to be the prime contractor on Fukushima 1, 2, 3, 5, and 6. www.pbnc2010.org.mx

Just a couple of questions after reading that article on Japan's possible nuclear program ? Where in the ocean is the heaviest radiation being detected, might that be where the 9.0 earthquake was located at ?
by wtm 4/13/2011 12:49:35 AM

@elainekirk Toshiba and General Electric were both involved on the designs, so I believe anywhere you see one you can assume the other helped for this plant. The credit just goes to one as opposed to the other for some reason.
by borrrden 4/13/2011 12:49:36 AM

@wtm Are you suggesting a test nuclear explosion off the coast?
by borrrden 4/13/2011 12:50:23 AM

@Borrden, wouldn't that be ironic ???
by wtm 4/13/2011 12:51:03 AM

Would the reactors be fitted with safety valves? if so why did they not blow when the vessels reached twice their design pressure?
by standbybarry 4/13/2011 12:51:14 AM

GUY'S, does anyone here have the article posted last night, that had the Nuke plant and Tepco communicating the night of the WQ ,11th via Videophone, that i doubted??.I would appreciate tit !!
by VeenOui 4/13/2011 12:51:22 AM

@standbybarry They might have blown.... If they didn't then it was just good design / good luck / etc.

[Good luck, perhaps, @borrrden. If my motorcycle heelmet did not crack to dissipate the impact of my fall, then my skull would have had to absorb all the shock, heh heh. - Alblee]

Positing that japan would be dumb enough to pop a large nuc at a known fault area, as a secret test, yes, that is a big step in hypothesis.
by Markfm 4/13/2011 12:55:36 AM

@VeenOui No, I just remembered the title of the article (alliteration...tepco tardy) and it popped up in my firefox super-bar when I typed it :)

[Also here in this room about 34 posts or so below this one. - Alblee]

@borrrden I can't remember article titles, i read so much, i go blank.
by VeenOui 4/13/2011 12:57:50 AM

"THE LOW LEVEL RADIATION CAMPAIGN

We research the health effects of ionising radiation
We demand a re-evaluation of the risks of radioactive pollution" ..... Has this article been posted? Are there opinions as to its accuracy? www.llrc.org
by Sky 4/13/2011 12:58:22 AM

@dean Interesting. I knew about Japan's WWII nuclear weapon research, but didn't know much about what they may be doing now. They certainly have all of the necessary pieces of the program if they decide to go with it.
by James Ward 4/13/2011 12:59:00 AM

@MarkFM, still would like to know about where that radiation is located in the ocean, remember that there were also "discharge" pipes that TEPCO acknowledged that went out directly from the reactors about 3 km into the ocean.

@Sky Dunno about the accuracy portion, but their biased objective is clear. They did provide a nice link to high-res photos of the site though cryptome.org
by borrrden 4/13/2011 1:02:42 AM

No disagreement on the pipe question. Where I live a nuc plant has pipes that go a couple miles off shore. I believe the purpose is to minimize environmental impact, but tepco seems to be pretty blaise as a corporation.
by Markfm 4/13/2011 1:03:59 AM

On fired steam boilers the safety valves have to be removed, serviced and inspected every year. I don't know how you would do that on a nuclear reactor.
by standbybarry 4/13/2011 1:04:30 AM

Puerto Rico is 2.9 sorry
by Debra Beckham 4/13/2011 1:04:48 AM

@Debra Beckham You're latest posted graphic doesn't show the 5.+ as high mag ?
by VeenOui 4/13/2011 1:04:58 AM

@Debra, almost always seeing a lot of small quakes on the San Andreas fault line in California, what is odd is the large amount of quakes now on lines parallel to the fault east of it.
by wtm 4/13/2011 1:05:06 AM

@standbybarry They xray them

[Hmmm, so they they don't have a shunted redundant valve for that particular circuit, eh? Well, I can see how awkward it would have been... - Alblee]

@ Debra -great tables. I'm hoping that last quake relieved the pressure further south. If ont then Tokyo is vulnerable
by UKVal 4/13/2011 1:06:12 AM

@MarkFM, many of us believe that TEPCO used those pipes to vent some of the pressure from the reactors out to sea, rather than let it be detected in the air around the plant.
by wtm 4/13/2011 1:07:14 AM

@wtm The East California Shear Zone is starting to take some of the stress from the San Andreas fault.
by FradyKat edited by alblee 4/13/2011 1:07:31 AM

@Debra Beckham Yeah, thank you, i was just curious...i have different data on my app.it's weird, the mag seems to differ depending upon site you goto
by VeenOui 4/13/2011 1:08:02 AM

I am going to redo both of those, I am finding differences between the USGS site & Global Incident (USGS shows more in US) and my excel sheet is a mess from playing with these numbers
by Debra Beckham 4/13/2011 1:08:29 AM

Thanks NHK Listener. Do you know if they did relieve on any of the reactors?
by standbybarry 4/13/2011 1:08:35 AM

earthquake!
by borrrden 4/13/2011 1:08:53 AM

@FradyKat Might wanna follow St Andreas all the way south to mexico.they keep rumbling
by VeenOui 4/13/2011 1:08:53 AM

@FradyKat, that seems to be the case, and let's hope for all that it continues with many small size quakes rather than load up and does a major "fracture" quake.

by edano via Freeimagehosting.net 4/13/2011 1:09:24 AM

@standbybarry yes the reactor and contaiment vessel have relief valves. the main steam line shows two on the P&ID's one on the containemt vessel on some of the diagrams.... with out actual drawing I could be off some... the first steam relief vent inside the containmt vessel to the torus... it shows a second further down the system out side the containment area... don't know if it is in the secaondary containment building or not... the drawing i saw show the containment vessel having a relief valve off the vesseel to the secondary containment building... the first relief may have vented to the tours I don't know... but the buildings blue up because something vented to the building if I am right, but you should ask dean... it get very complex.... there was a report from a worker that stated they were unable to breath and there was smoke or steam before the Isaumi ever hit,,,,,, don't know which one you are looking at and waht day... after the explosions who knows what valves worked they lost a lot of equiomet and piping componts... but yes they do have relief valves....
by fitter 4/13/2011 1:10:03 AM

@wtm Yea, the Owens Valley quake was one of the biggest ever in the west US.
by FradyKat 4/13/2011 1:10:34 AM

7.2 estimated magnitude off the coast of Fukushima

@borrrden What ??.so fast prelim ?/

That's exactly the visual we need to see ! Thank you for creating the overlay...well done. Just look how the radiation follows the highway...wow !
