@fitter Not that I have found.

@Nancy looking at TEPCOs plan that was out yesterday, I belive they are going to use the line that now puts in the nitrogen, and are running a new by-pass for the nitrigen... but have not confirmed that.... also they note that they need to verify the damage, its only a game plan at this point.... they are suppost to due the survey in a few days after they get the rads under control

Highlights from JAIF: 2 workers entered #1 to install a purifier for the air filter system. Groups of 3, wearing 30 pound air tanks, will work about 10 minutes/group installing 8 air ducts. Air purifier needs about 3 days to hopefully clear it enough for workers to stay inside for longer intervals. As soon as Sunday they hope to have workers start doing pipe/valve checks in preparation for setting up the new external cooling system. Open questions -- Will the air purifier be able to clean the air enough? Will the areas near pipes still be really radioactive, maybe need lead sheeting for protection? How to make any needed pipe/valve repairs? To circulate water, the WL needs to be brought up to the top of the rods, however dropping pressure, part of the evolution of adding more water, may risk another hydrogen explosion.

@Markfm do you have the link

@Markfm good moring
by fitter 5/5/2011 1:03:49 PM

More JAIF: The new water cooling system is planned to circulate about 100 tons/hour of water, to cool the estimated 1500 KW of heat generated in the reactor. If it works well, temp should drop below 100C in anywhere from a few hours to a few days.

be back later... UT time..
by dean 5/5/2011 1:07:31 PM

@Markfm the cam flash on building two last night reminded me a welding area, it also looked to be at the roof level, top of steps (I think 2 still has steps), but my view ot the live web was not working well so i could not tell if the flash was having breaks... if welding you would have periods with not flash.. did anyone ever figure out what that was ???

@dean have a good day dean, need to go also.. Mark ty

I should be back in about 4 hours if anyone needs anything.

No idea what the light is at 2.

Radiation measurement in Tokyo soil (Japanese) www.asyura2.com logsoku.com It is unclear from the translation whether this refers to Cesium-137, or Cs-134 also, or something else. 30,000 Bq/m^2 of Cs-137 is higher than what Kiev received during Chernobyl.

Good evening again all, have fed the neighbors and am back
by bo 5/5/2011 1:32:22 PM

Just a pet peeve, People in the know, realize that radioactivity is a substance, Like a light bulb, and Radiation is the result, Like light, I hate when the "experts" cross the two and use them interchangably. If you are exposed to a radiation level (ex. 5 micro SV/hr) then you got it and it is over. If you walk through a Contaminated Area, Where radioactivity is present, you take it with you, and it continues to give you radiation dose, until it is removed, physically.

Looking at plant parameters 5 vs. 4 May. Unit 1 continues to pick up 20 kPa core pressure/day, other parameters stable. Unit 2 has little change except in S/C B CAMS -- up another 31 Sv/hr, showing 84 Sv/hr today (something must be getting near that sensor again.) #3 Water level A is now showing -2050 mm compared to -1850 yesterday, another noticeable core temp rise (157C feedwater and 144C bottom head of RPV vs. 123C and 139C yesterday), Drywell RPV bellows seal temp is up 40C at 228C, drywell return line to HVH is up 18C at 118C.

I don't know how long this has been the case, but the unicamp graphs are back. For reactor 1 www.ic.unicamp.br it gives a clear picture of the higher-flow experiment and the quick temperature and pressure drops. The drywell pressure was about to go below atmospheric pressure when they stopped. I guess that might suck in some oxygen from outside.
by Martin via Ic.unicamp.br 5/5/2011 1:47:08 PM

On #3 they've also boosted the water injection, going from just under 7 cubic meters/hr to 9. Hopefully that will help knock the temps back down.

@RBeaner Thanks for pointing that out. Do you have any concern for the tens of millions in Japan who have been exposed to higher amounts of radionuclides than many areas of the Ukraine and Belarus, who are still getting sick and dying 25 years after Chernobyl?

Workers enter Japan reactor for 1st time since blast www.reuters.com 2 TEPCO staff, 11 contractors. "no possibility of another hydrogen explosion at the No.1 reactor due to progress in filling the containment vessel, " Noted that the rising temp in #3 is a watch item, and that sea sediment with 10000x normal radioactivity was found near the plant.
by Markfm 5/5/2011 2:13:35 PM

@Mark horses, stables and doors. What sickens me is that hamaoka did all the surveys etc requested of them in '06/07 and upgraded their plants in the manner requested of them at the time by the governmemnt agencies, they scrapped 1& 2 in the processd as they were Fukushima style bwr's and upgrading would have cost too much.
Contrast that with Tepco who didnt do the work/surveys/sonar requested of them even though in '07 another of their plants was damaged in a quake and you have to ask yourself who is running Japan......methinks irt be Tepco
by elainekirk 5/5/2011 2:19:42 PM

Workers enter Japanese reactor for first time since quake www.latimes.com Another take on the initial work, some amplifying information. I believe the reference to 30 lb fire extinguishers is erroneous, it is probably supposed to be the 30 pound air tanks they breathed off of.

Whoever has the best "in" with the bureaucrats gets the most slack -- it happens everywhere, unfortunately.
by Markfm 5/5/2011 2:21:58 PM

@Mornin! Anything in on what they found?
by Jim Carver 5/5/2011 2:29:15 PM

I'd love to know what happened in unit 3 on the 29Apr. Almost all it's parameters jumped up. Wonder if it has something to do with bo's observation re: radiation level spike, tho he's abot 300km away, iirc.
by marie rich 5/5/2011 2:32:13 PM

impressive memory @marie rich
by bo 5/5/2011 2:33:19 PM

I'm still trying to find a connection, bo. I just can't find a real link to it.
by marie rich 5/5/2011 2:34:09 PM

@marie rich That would explain the 5-fold increase in Iodine-131 detected by the CTBTO 4-5 days later in Virginia and Kansas.

@elainekirk Looking around doesn't look like they've reported any readings yet.

"closed water loop is only partially achieved...leaks from rpv and containment" HUH!!??
by marie rich 5/5/2011 2:58:18 PM

"you can see smoke from the units, but this was from the 28th, because it wasn't good to take pictures (since)" What? We've seen plenty
by marie rich 5/5/2011 3:03:51 PM

So the guy talking about radiation levels only editorializes about the low readings in water and food. No comments about air levels...hmmm. And they only have data from Tepco and GoJ...hmmmm
