Japan Nuclear Crisis Part III

that's at normal operating temp though...this reactor is scrammed...pretty crazy it's that high.

I recall during the last week that 375c internal water temp was a key factor for being able to have the correct pressure/temp to maintain liquid.

Not sure if those reactors have water in them...certainly enough......if they melted....the sea water injected to cool the core at the bottom could be low or gone. Will check with the old man tomorrow....but he was very mindful that if they lost all monitoring.....thermals on the vessel were critical to surmise internal state.

It's there...funny refresh. two bits of bad news about an hour ago.

NEWS ADVISORY: No. 2 reactor power repair work halted, 500 millisievert per hr radiation foundico_note.gif<LI class=note>11:10 23 MarchNEWS ADVISORY: Fukushima No. 1 reactor temperature rising, water injection up: agency

You were right. It was pulled down for a few minutes. Then they stuck it back up.

Hypothetical situation.

If the cores melted at 1, 2 and 3 what is the worst case scenario as far as radiation directly around the plant itself? if the cores are melted, will there still be extremely hot temperatures? We already know there isn't going to be an explosion alla nuclear bomb, but what would a full core meltdown actually look like?

Clear as mud...... From the above linked article as of minutes ago:

A level of 500 millisieverts per hour "days ago" at the No. 2 reactor turbine

forced workers to suspend repairs and they have yet to restart, Hidehiko

Nishiyama, a spokesman for the Japan Nuclear and Industrial Safety Agency, told

reporters today.

Workers are attempting to restore an electricity-powered water pumping system at

the No. 3 reactor by tomorrow, reducing the need to spray the unit from outside.

Temperatures at the No. 1 reactor pressure vessel exceeded 400 degrees Celsius

(752 Fahrenheit) before water spraying brought it down to 390 degrees, Nishiyama

said. Two workers were injured overnight while working to restore power, Kyodo

News said, citing Tepco.

So the spraying lowered the temp by something more than 10C? From "more than" 400 to 390? That was worth the risk! Oh my!

WOWOWOW!!! They have a lot of nerve with this garbage...I'd be very concerned if I lived in Japan.

FROM TEPCO: "From now on, if the measured figure fluctuates and goes above and below 500 micro Sv/h, we deem that as the continuous same event and will not regard that as a new specific incidents stipulated in article 15, clause

1 of the Act on Special Measures Concerning Nuclear Emergency Preparedness (Abnormal increase in radiation dose measured at site boundary) has occurred. In the interim, if we measure a manifestly abnormal figure and

it is evident that the event is not the continuous same event, we will determine and notify." www.tepco.co.jp

In other words....We are not going to report anything short of Chernobyl.

Yikes highest in a long time.

Bad, I think this lower level radiation over the long term is as big of a nightmare and in the end they may still need the martyrs to bring it under control.

I kinda have the feeling they already are. I mean I doubt they're going to do what the russians did and give people lethal doses in 2 minutes, but from the readings and work described it seems that these workers must be accumulating a pretty massive amount of radiation.

1 hour of 500 millisievert is a huge increase in cancer risk. 10 hours at the plant is 5 sieverts. Call me crazy but that's deadly.

Something is afoot with the 500 millisieverts per hour level of radiation.

Temperatures at the No. 1 reactor pressure vessel were brought down to 390 degrees. Water boils away at 212 degrees.

Tap water has iodine 131 / Tap water in friggin' TOKYO has got iodine 131 in it

Some food in Japan is unfit to consume because it is radioactive

IAEA has nothing but positive news.

Get out of Japan NOW. Don't eat the food/don't drink the water. Japan is horrifically FUCKED.

Sure I'm just a bit concerned for California - I'm probably wrong - There's probably nothing at all to worry about in western North America at all from this - My IQ is about 5 - But if the reactor temps can't be brought down and the radiation levels rise and workers can't fix the problems............

Please go away and don't post in this thread anymore.

This guy has been a really good source for timely updates from some of the pressers....

  1. Radioactive Iodine in Tokyo water at 210bg/l on Tues, prelim Wed at 190bq/l. Limit for infants 100bq/l; adults 300bq/l http://bit.ly/ijZCF8 1 minute ago via TweetDeck
  2. @newtownenglish http://bit.ly/hqbPbR 6 minutes ago via TweetDeck in reply to newtownenglish
  3. Other purification plants have not shown same level of radiation, but caution on children drinking extends to all 23 wards - Tokyo govt 12 minutes ago via TweetDeck
  4. Radiation was detected only at Kanamachi water purification plant, in Katsushika-ku. Takes water from Tonegawa, Edogawa rivers - Tokyo govt

Yeah... this ain't good.

Japan Sets Safe Limits for Consuming Radiation-Contaminated Food

The prescribed safe limit for I-131 in vegetables is set at 2,000 Becquerel (Bq) per kilogram and 500 Bq/kg for radioactive cesium.

The spinach contained 54,100 Bq/kg of I-131 and 1,931 Bq/kg of cesium. That means consuming 1 kilogram (2.2 pounds) of fresh spinach would yield a radiation exposure of 1.2 millisieverts, or half the average annual natural exposure from soil and cosmic rays, based on Bloomberg calculations using a formula posted on the website of Japan’s Food Safety Commission.

Now read this from a few days ago...

http://www.bloomberg...-tap-water.html

Japan Says Small Amount of Radiation Found in Tokyo Tap Water

Tochigi Prefecture’s reading of radioactive iodine-131 was 77 Becquerel per kilogram, the highest among the prefectures, while the level of iodine found in Tokyo’s Shinjuku district was 1.5. All the numbers were within the 300 Bq/kg limit, the ministry said.

Keep that 300 Bq/kg number in your head.

Oh now a few days later...

http://www.bbc.co.uk...acific-12825342

Levels of radioactive iodine-131 in some areas of Tokyo is 210 becquerels per litre; the safe level for infants in 100 becquerels per litre.

Remember those people that Japan told to stay indoors near the plant and to close the doors and not venture outside? Whatever happened to those people? Can they go out yet? Amazing how they've been forgotten about. If the tap water in Tokyo is at 210 bq/kg, imagine what it is up there!!! Logic would suggest that it would be much higher.

And now we're up from 77 to 210 bq/kg. I wonder when we're going to hit the magic 300 number.

The flow of information here is terrible all because they're trying to protect their precious little stock market. What about trying to protect the people of Japan???

I don't get why ALL the International agencies are not regularly monitoring independently - then reporting to the rest of the world. What, has Japan cornered the market on radioactive emissions news??? Where are the other agency PLUME MAPS? UPDATED. Daily or Real-time. This blows.

Things became really quiet since the IAEA said that Japan needed to release more information. It's become quite obvious to me that all have decided it's better to keep quiet about certain things.
