@Debra Beckham That story fails to mention that May 20 is the big annual seaweed harvest for Japan.

@radioguy Why is that not a surprise? Criminal governments running the world without a care for humanity, and lacking in compassion or concern. We are nothing to our elected officials unntil they need the vote or more money

@Pedro Jesus Retrofit is way more difficult than building to use alt. energy. We are going through all of this right now. We want to put solar shingles on our huge garage roof. The cost of the shingles isn't horrible but all the other logistics since we can't just tie into the grid makes it more costly to run dual systems.

@Pedro Jesus Where I live in the US is very conservative and always about 5 years late on any trend. We have seen more builders start doing green building standards, better efficiency and some alt energy like heat pumps that work with traditional utilities. I will consider it a big move when one puts in solar or wind of some sort on a new house as more than a show house.

The ground water issue had me wondering, if this stuff is entering the water table below the plant, does that water source flow away from the area? IE: underground rivers, connected areas of the water table etc? I don't know enough about geology and how water tables operate to know how much of a possibility it is.

@lillymunster Ok I need sleep now lol 1am here! you right till elaine comes?
by Angie 5/13/2011 2:57:38 PM

@lillymunster I've been wondering that as well. As they have found radioactive sewage sludge fairly far away I'm beginning to think that there is at least some potential seepage further from the plant. We need a geologist who knows that area!

@lillymunster From the link, "The limit set for food by Japan is 2,000 Becquerel (Bq) per kg for radioactive Iodine-131 and 500 Bq/kg for radioactive cesium." The limit for I-131 is very high. The EPA standards for drinking water is 3 pCi/liter of I-131 and 200 pCi/liter for Cs-137.

@lillymunster, everybody, did tepco ever publish plant parameters for Mar. 11?

@lillymunster @LM There was a groundwater flow map that came up on here possibly a month ago. IIRC someone said it it showed flow to the ocean, rather than the other way, though anyone who's had wells on an island knows the flow is not one way.

Noon 12 May vs. 6:00 13 May reactor changes (from plant parameters): 1 is stable (leaking like a sieve, but reported parameters pretty much unchanged). 2 is stable (still big Drywell B radiation reading, but decreasing as is typical after it builds to a large value). #3 RPV injection is interesting -- looks like there was a change in rate, added another 3 cubic meters/hr, so now they're injecting almost 12/hr. #3 RPV temps decreased, going from 189/149C to 171/146C, with drywell temps also dropping, from 198/134C down to 180/131C.

@Bobby1 And people look at that comparison and the eyes glaze . o O (so let's see... is that times 37 or divided by 37 oh dear I don't know my 37 times tables... and is a scale of thousands oh i give up.)
by radioguy 5/13/2011 3:19:03 PM

Peter, 11 May plant parameters: www.nisa.meti.go.jp (They actually published numbers from 23:00 on 10 May, then the next report isn't until noon on 12 May, I believe).
by Markfm 5/13/2011 3:20:48 PM

@radioguy It's something like 250 times too high.
by Bobby1 5/13/2011 3:21:35 PM

Going to be out of the office for a few hours. Will try to check on my phone while I am out in case anyone gets stuck in moderation.
by lillymunster 5/13/2011 3:22:05 PM

@Radioguy -- it might have been something from Alaskan. It's just the topology, land gets higher going inland, so you have downward flow towards the ocean.
by Markfm 5/13/2011 3:22:37 PM

@radioguy The tide is a very important factor in this . www.google.com
by Majjham Zazen 5/13/2011 3:25:06 PM

@Majjham Zazen Oh carp. I had forgotten about the new tide lines.
by radioguy 5/13/2011 3:26:28 PM

So the water table will have to adjust to that new level. I wonder how long that takes.
by radioguy 5/13/2011 3:27:12 PM

Reactor 1 in worse shape than thought search.japantimes.co.jp (sorry if these have been posted -- I do this when I update the wiki News page) It has a nice little graphic, showing the water level below rod bottom, glob of corium at the bottom.

@Markfm, I meant MARCH 11, but thanks for the link to the nisa archive. I shall dig deeper.
by Peter Melzer 5/13/2011 3:28:30 PM

@radioguy Is curios to know if the TEPCO contamination tests in the ocean is made at Incoming tide or going down tide....
by Majjham Zazen 5/13/2011 3:29:09 PM

Didn't elaine have a list of March 11 parameters?
by radioguy 5/13/2011 3:29:35 PM

Newly gleaned... there was that photo, bad resolution, and then she searched and found the list?
by radioguy 5/13/2011 3:30:21 PM

@Majjham Zazen Whichever time is least damaging.
by radioguy 5/13/2011 3:30:38 PM

My error. First data I'm seeing from Josef Stolfi's data mining is from the 13th of March -- there's one line for the 11th, but all values 99999. www.ic.unicamp.br

@radioguy Tide going in you have clear sea water from the see infiltrate the land,going out you can imagine ...... I will stud the tide ranges in NE Japan

@Majjham Zazen To get meaningful numbers they should measure both (and probably do). Whether they'd release meaningful numbers is debatable.
by radioguy 5/13/2011 3:36:13 PM

Nuclear fuel rods may have mostly melted www.yomiuri.co.jp Better graphic, shows where the WL was reported (-1.65m), vs. what they found when they calibrated the instrument (-5+ m). Not sure if I've seen anyone ask the question -- given the WL was so whacked, any confidence in the temp and pressure sensors?
by Markfm 5/13/2011 3:39:44 PM

@radioguy The tide is parameters is easy. How much the land sank in more problematic... I will try any way.
by Majjham Zazen 5/13/2011 3:40:03 PM

From the Yomiuri article: "More than 10,000 cubic meters of water had been injected into the reactor as of Thursday, exceeding the combined 360-cubic-meter capacity of the pressure vessel and the 7,800-cubic-meter capacity of the containment chamber.

It is highly likely that water is leaking from both the pressure vessel and containment chamber and flowing into underground parts of the reactor building and the adjacent turbine building, TEPCO officials said.

To proceed with the water-entombment, it is necessary to accurately grasp the water level in the containment chamber and the conditions of pipes that take in or release cooling water, experts said."
by Markfm 5/13/2011 3:41:45 PM

From the "glass if half full" view, NISA: no need to flood No.1 reactor www3.nhk.or.jp "Nishiyama said TEPCO need only inject water to a height that would allow the system to work.

He said the utility will likely change its strategy and inject water to the minimum necessary level." Of course, no clue about where the leaks are, no input on what will happen to that admittedly low WL if they reduce injection rate, ... Just be happy. Measured pressure in #1 is showing stable or slight decrease on the higher reading, a bit of increase on the lower reading, at 14 and 5.9 atmospheres absolute.
