@all: will be away for 1 week, with no internet... Here's my last review before I go.

my reactor of the day is #1, which seems stabilizing.
RPV temperature has dropped below the boiling point with a good margin (20 °C), drywell one is just above the boiling point (2°C). It still seems to me the drywell has no heat source and is heated by the RPV, which would mean there is no fission running here (this does not mean there is no fuel that has escaped though). The torus seems mostly intact and the pressure in this area would suggest most water is leaking at the level of the steam pipes between the reactor and the turbines (or in the turbine building itself)
Note: according to google translation from Japanese to english, NISA reports say that nitrogen is being injecting into the "sealed containment Reactor", which in my opinion would be the RPV and is consistent with the pressures readings we have.

#2. Nothing changes, it's a mess.
Water is boiling in the RPV and in the drywell. Temperature in the drywell still suggest me there's a huge heat source there, then free running fission. Here's what I think about the "strange" torus CAMS readings: BWR is likely to have fuel leak in the torus in case of LOCA accident; given there is a lot of water flowing from the RPV to the building basement through the torus and broken fuel in the RPV, the broken fuel is likely carried outside through the torus. There are 2 possibilities:
- a lot of broken fuel has deposited in the torus, at the point there is the less water flow (opposite to the breach); this seems unlikely to me.
- a lot of broken fuel is carried out by the water flow and #2 CAM sensor is near the breach, then "sees" the fuel being carried away; this is what I think is happening; it would explain why the torus temperature is not very high: there would not be enough grouped fuel debris here to run a fission reaction; but it would also mean the fuel is finally leaking to the building basement and that free running fission could happen there which would be very bad.

#5 seems to leak more water than it did one week ago: it seems leaking about 20 to 25 cm a day, which would be 4 to 5 m3 a day.
#6 seems stable, water level dropping nearly 15 cm a day, when not reffiled.

I took some to see the bots videos; I found the videos quality very good given the conditions (low quality capture of a PC QCIF video, could be much uglier) : one can note that water condensing on the camera lens is a reason for lots of artefacts, the other being classical energic compression ones. Cryptome pics are worse than the videos: same base resolution, upscaled, with a smoothing filter applied (which is not a good idea in such a case), but lots of artefacts added by a faulty deinterlacing filter; quite a classical problem when processing interlaced videos...
No doubt for the location of #3 videos: seeing the sunlight from inside a reactor building entry is not likely to happen, but if the building is badly damaged...

lets just say it is very warm around those parts.

@all I now need to have lunch; I may not have time to come back until I go.
Then I wish you all a good time and hope nothing bad will happen !
Thanks for keeping your eyes opened and share !

@Scilla: as #2 torus is broken, its basement should be flooded.
#3 and #4 should also be because of the tons of water that have been spread on them to cool the SFPs. #1 may not...

By the was that was 97 microsieverts an hour they was measureing so that would be heading for 1 mili sieverts in 10 hours.

i hope i am correct and that was micro and not milli they were measureing.

@all the tepco cam pics on the previous page. That massive steam is coming out of #4. I need to check if we finally got heat images. Nothing out of TEPCO yesterday as far as images of any kind.

@all. 1. if you see xxx here today he needs to get with either my or Jim so we can get a copy of the 100 related you tube videos he downloaded. 2. If you find anything you think needs to be archived make sure you say something so one of the people with server access can make a copy.

just after the first video of them i posted i put there coments in google translate and posted that, i think they are people who wanted to check out what was going on for themselves before the place was shut down.

@e123 Thanks, thought maybe you found them via somewhere with more explanation. I will see if I can download copies and put in the archives.

Looks like TEPCO is planning to instrument #4 pool -- temp, depth, radioactivity: translate.google.com

@Majjham Zazen you can email them. Could you maybe put them into a zip file? If you have dean's email you could send them to him or you can email them to me at lillymunster (at) gmail.com

@Nancy I finish clean then now and in 30 minutes I send both to emails . I will Zip. them. My pleasure :-))))

@Majjham Zazen Thank you so much.

@markfm: about nitrogen injection, I tried to translate directly from NISA japanese reports; but Tepco should know better... Should have checked here before posting !
But the pressure increase in #1 RPV cannot be explained with steam generation now that the temperature has dropped, or if the temp data are completely false (which is possible); hope they really are injecting nitrogen here.
