* Man lived 25 miles from Fukushima plant but exclusion zone was extended
* Prime minister Naoto Kan faces calls to step down over handling of crisis
* Police search wasteland for up to 1,000 bodies of people still missing
A 102-year-old Japanese man, one of the oldest residents for hundreds of miles around, has taken his life because he did not want to leave his home in a newly-declared radiation zone.
The centenarian lived in the village of Iitate, which until earlier this week was declared safe from radiation pouring from the crippled nuclear plant at Fukushima.
Government officials earlier insisted that anyone living within a 19-mile radius of the plant must move and either stay with distant relatives or take shelter in an evacuation centre outside the zone.
… Seiji Shiroya, a commissioner of Japan’s Nuclear Safety Commission, an independent government panel that oversees the country’s nuclear industry… suggested a public policy reason for having kept quiet.
“Some foreigners fled the country even when there appeared to be little risk,” he said. “If we immediately decided to label the situation as Level 7, we could have triggered a panicked reaction.” …

10 Bar = 145.038 PSI.
Given the massive size of these vessels, that is a hell of a lot of pressure. Especially if it is water pressure.
Found this graph on the same site, and another one listed below first one. Maybe you can make heads or tails of them.
And numbers chart.
Well, this spreadsheet is for internal consumption of the Nuclear and Industrial Safety Agency & Ministry of Economy, Trade & Industry, it's on a secure server that they didn't password protect the files. I don't know how long this link will be available!
A rough transliteration of the spread sheet column headings: a=date, b=atomic furnace level A (mm), c=nuclear reactor water level B (mm), d=atomic furnace pressure force A(Mpa g), e=atomic furnace pressure force B (Mpa g), f=pressure vessel water temp (ºC), g=lower pressure vessel temp (ºC), h=DW (Mpa abs), i=SC (Mpa abs), j=DW CAMS (Sv/h), k=SC CAMS (Sv/h)
On the bottom of the spreadsheet are selection boxes, starting from the left, clicking the first box gives you the spreadsheet for the reactor selected from 3/15, the second box gives you a chart of pressure force A&B, the third box is a chart of pressure vessel water temp upper & lower, the forth box will give you a spreadsheet of readings from ~3/15. The left right arrows on the bottom will scroll the bottom boxes to the next reactor, using the same sequence for the display. Reactors 1,2,3,5,6 are on this spread sheet. 4 is not there!
Oh, and thank Masato-san for posting all this info, his twitter address is on the spreadsheet!edit on 14-4-2011 by Tworide because: (no reason given)edit on 14-4-2011 by Tworide because: (no reason given)edit on 14-4-2011 by Tworide because: spelling

I would agree with the fact that we would expect cesium 137 or other elements in the soil or groundwater around Oak Ridge, but since the samples are of "precipitation", do you think some Cs-137 is somehow still escaping from Oak Ridge to mix with atmospheric rainwater? Or does EPA maybe have a problem with collection procedures there?
I was more interested in views on I-131 spikes in places like Jacksonville, Kansas City, Salt Lake City, Nashville. These cities are far enough apart that the fallout could be considered North American continent by now.
I understand that I-131 has been downplayed due to the relatively short half-life. But if I-131 is around in any abundance, it is almost certain the Cs-137 and certain others will follow on dust, soot, and smog particles then eventually rainwater.
ETA: does anyone want their little kids playing in the rain with 200 pCi/l of I-131 for any amount of time?edit on 13-4-2011 by 1SawSomeThings because: question,spelling
The No. 1 reactor of the Onagawa nuclear power plant in Miyagi Prefecture on April 7 sustained a jolt greater than what it was designed to withstand during a strong aftershock from the powerful March 11 earthquake, according to nuclear safety officials.
The finding raises further doubts about the viability of the assumed quake resistance at the Tohoku Electric Power Co. complex, even though it had been shut down safely after the deadly quake last month.
On March 11th 2011, turbines and reactors of Fukushima Daini Nuclear Power
Station Unit 1 to 4 (Boiling Water Reactor, rated output 1100 Megawatts) that had been operating at rated power automatically shutdown at 2:48 pm
due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake (previously announced on
At 7:15 pm on March 15th, the reactor of Unit 4 achieved cold shutdown. As
a result, all reactors of Unit 1 to 4 at Fukushima Daini Nuclear Power
Station achieved cold shutdown (previously announced on March 15th).
As of 4:00 pm on April 14th, the reactors of Unit 1 to 4 are in cold
shutdown (please refer to the attachment). We continue to make our endeavor
to stabilize each plant.
At the time of the quake, reactor 4 had been de-fueled while 5 and 6 were in cold shutdown for planned maintenance.

Ok found some sources which indicate AREVA were attempting to use 50 - 100% MOX in some newer PWR designs (AP1000) but they could have tried to retrofit Mk1 BWR's with 50% - 100% MOX fuel assemblies.
This would be illegal under the Nuclear authorities rules and would have required observed secrecy under white blankets etc.
In short if AREVA were to create 100% MOX fuel use in older BWR reactors. They would make way more money because there are more older reactors and new reactors take time and a lot of money to build.

1. Current Situation
Overall, the situation at the Fukushima Daiichi plant remains very serious but there are early signs of recovery in some functions such as electrical power and instrumentation
There have been no changes concerning the provisional INES Level 7 rating and protective measures as reported in yesterday's brief.
Q+A-Risks at each reactor of Japan's stricken plant By Mayumi Negishi and Chizu Nomiyama
TOKYO, April 14 | Thu Apr 14, 2011 6:48am EDT
-- REACTOR No 2: 784-MW (Manufacturer: GE, Toshiba)
This reactor is flooded with the most deadly waters. A worker would exceed his annual quota of radiation after just 15 minutes in the basement of the turbine building.
Workers have transferred 660 tonnes of the radioactive water out of basement and reactor's tunnel into its condensers, but the water level failed to go down by much, and workers now plan to pump water to tanks on the site's central radioactive waste facility.
If engineers cannot pump out water faster than it leaks back in, TEPCO might have to set up an external cooling pump system outside the turbine building.
Nobody wants that water dumped into the sea. Japan has already dumped low-level contaminated water into the ocean to make space to store the more toxic water on site, drawing international criticism.
Engineers are now struggling to cool the reactors to the point where they can be safely shut down. Until the cooling pumps, or alternatives, are online to continually cool the reactors, workers are forced to periodically inject new water to keep the fuel cool, but that creates more contaminated water.
The immediate challenge is to transfer and store the contaminated water, while at the same time limit as much as possible the spread of radiation still leaking into the atmosphere and sea. At the moment, workers do not have access to the cooling systems in reactors No.1, No.2 and No.3.
So far, eight workers have sustained injuries from radiation at the Daiichi plant. All have been released from hospital

Reactor A# 4. At the time of the earthquake and tsunami on March 11, the reactor was undergoing maintenance, and all fuel had been transferred to the spent fuel pool.
Four days after the quake, the spent fuel pool caught fire and caused an explosion. Japan's nuclear safety agency said the blast punctured two holes around 8 metres square in the wall of the outer building of the reactor.
The pools contain racks that hold spent fuel taken from the reactor. Operators need to constantly add water to the pool to keep the fuel submerged and trap radiation.
TEPCO sampled the water this week and detected small increases in radioactivity in the water. Nuclear authorities are trying to gauge if the increase in radiation is airborne or from damage to the Unit 4 fuel.

Uncalled for and harsh assessment.
D you expect everyone to make you happy with robotic and emotionless reporting of straight facts and data?
It's a tough and emotional subject that posters have been spending a great deal of time immersed in researching, reporting and reading AND there has been a great deal more self control than lack thereof in posting emotional rants, commentary and far out speculations.
Much gratitude to all involved for their dedication to gathering an presenting this information and being human
