@radioguy - Re: Gauges, apparently we could export the gauges to their own spreadsheet. For the web, we use the embed HTML that the Gadget generates and the site web page can array and identify the gauges, perhaps at about 33% of actual size. Perhaps we use another google charting gadget to display the reactor data over time, such as: Google Interactive Time Series Chart?

@elainekirk ty would appreciate it

Containment vessels also damaged
The Yomiuri Shimbun
Not only the pressure vessels, but the containment vessels of the Nos. 1 to 3 reactors at the Fukushima No. 1 nuclear power plant were probably damaged within 24 hours of the March 11 earthquake and tsunami, according to Tokyo Electric Power Co.'s analysis of the nuclear crisis.
In a report on the analysis, the utility said it carried out minute calculations on internal pressure and other measurements in the nuclear reactors after the earthquake.
The report was submitted to the Economy, Trade and Industry Ministry's Nuclear and Industrial Safety Agency on Monday night.
TEPCO said it found that an isolation condenser, a type of emergency cooling device, did not work properly at the No. 1 reactor. This caused the core meltdown to progress until it damaged the bottom of the pressure vessel about 15 hours after the earthquake.
Along with the meltdown, the temperature inside the steel containment vessel, which contains the pressure vessel, rose until it reached 300 C in 18 hours after the quake, much higher than 138 C the vessel was designed for. It is believed the internal temperature continued to rise after that.
Containment vessels are designed for a much lower temperature and pressure than pressure vessels, which can be exposed to temperatures close to 300 C and pressure reaching 70 bars when a reactor is in operation.
Rubber and metal parts used to seal pipes and other devices in the containment vessel apparently deteriorated quickly under temperatures exceeding 300 C. This may have caused steam containing radioactive materials to leak, the report said.
The pressure inside the containment vessel reached 8.4 bars 12 hours after the quake, which is nearly two times the pressure it was designed for. Damage to the containment vessel might have progressed faster than the analysis, TEPCO said.
On the basis of fluctuations in pressure measurements inside the containment vessel of the No. 2 reactor, it is assumed a 10-centimeter-diameter hole appeared in the side of the vessel, causing steam to leak 21 hours after the quake.
If there was no leakage, the rise of internal pressure would have been much sharper. This makes it difficult to explain the actual pressure measurements.
Damage in a pressure control chamber has already been acknowledged, but damage to the containment vessel itself has not been confirmed.

And now goodnight - see you tomorrow!

The issue of children in Fukushima FINALLY made it to the US media www.nytimes.com

@ Nancy page still not found.

@carabnr I bet you can't see the preview without being logged in. Will send a fb message to figure it out

@Rob in SF That's what I was thinking. Anything that needs those data cells can be given what it needs as a range and do its thing. We'll want a group GoogleDocs site to feed it from.

@Elaine, Carabnr, no this looks more like it is coming out from the cliffs ?? My thought is maybe some steam/hot water that is pouring out from the ground from the cliffs ? Don't see anything else that would cause that in that area ?

@Dean, Fitter had a question for you to answer, something about the effects of hot metal expanding in relationship to seals on the RPV unit. Nancy might be able to elaborate on his question also.

@Nancy, in the earlier pic, the cloud or steam ? was bigger than what is pictured this hour.

@Nancy, don't know where to find one ?

@Dean, fitter's question was wondering about heat expansion of metal and pipe connections. IE: how do they keep a sealed connection to the RPV and deal with expansion and earthquake movement.

@dean hello all pc frezzing up... one of the questions : how much difference in the cold reactor and the expanded reactor due to full heat load, 2: how do they allow fir this in supppoet system do you know for were you work???? may not be able to responded if gremblins retu

@dean example would be your steam loop due to the actual growth of the steam line at higher teemps. vessel would have similar properties.. cold shutdown vs full power.. also do they
