Reactor meltdown possible in Japan.


Recommended Posts

yes article 15....

when did they do that for the 1st reactor? and why didn't they do them at the same time if all have the same problem

You can see all the press releases here:

Looks like this is the latest status update for reactor 3 at 9 AM:

Reactor has been shut down. However, High Pressure Core Injection System has been automatically shut down and water injection to the reactor is currently interrupted. We are examining alternative way to inject water. Also, following the instruction by the government and with fully securing safety, steps to lowering the pressure of reactor containment vessel has been taken. Spraying in order to lower pressure level within the reactor containment vessel has been cancelled.

They issued a article 10 for all three of the reactors right after the earthquake hit and then a 15 for 1 and 2 soon after.

ok so there are 2 articles .....article 15 was issued when they had to vent...so that happened at number 1 sooner then number 3 hence the different times ,...gotch ya

just took a look at the GFS model over there in Japan. and as i can extrapolate it, there are two risk periods for easterly flow for central and northern japan in the next several days, synoptically speaking. both are lows spinning up on the tail end of a front lee-side of the japanese mountains. the first time period that i can quickly extrapolate is 12Z monday to 00Z tuesday, and the other one is with a secondary spinup between 15Z Tuesday until 00Z wednesday. once we get past 00Z wednesday, we should go back to a westerly flow for about a week's time. if there are any experts here that are used to forecasting over there and know the local effects a lot better, maybe you could correct me on the potential with the upcoming systems. but that's what I am seeing attm.

Seeing something like this does make you wonder wtf is going on. Now they reach out for help/advice from the maker of the #3 reactor along with two of the reactors at the Daini plant.

URGENT: Kan asks Toshiba head to help address nuke plant disorder

TOKYO, March 13, Kyodo

Prime Minister Naoto Kan on Sunday instructed Norio Sasaki, president of Toshiba Corp., maker of the troubled reactors at the nuclear power plants in quake-hit Fukushima Prefecture, to do all he can to contain the problems at the plants.

Kan gave the instruction to Sasaki during their talks at the premier's office after a devastating earthquake hit the northeastern and eastern regions of Japan on Friday and led to the shutdown of the Fukushima No. 1 and No. 2 nuclear plants.

Japan’s chief cabinet secretary says there’s a risk of explosion at the building housing Fukushima Daiichi no.3 reactor

Report just in that TEPCO has begun to inject seawater to cool the Fukushima Daiichi no.3 reactor

Japan's Chief Cabinet Secretary Yukio Edano says that even if Fukushima building explodes it is unlikely to affect reactor core container

TimeOutTokyo TimeOutTokyo We should repeat: The reports emerging now are for Onagawa Nuclear Plant, not Mekawa. Images currently showing on NHK.

TimeOutTokyo TimeOutTokyo Onagawa Nuclear Plant is in Miyagi Prefecture, about 100km from Fukushima. http://bit.ly/i2J3EL

I think they are praying/hoping that if any explosion were to occur that it wouldn't breach the secondary containment and suggesting that it can resist it if on were to happen.

Checking to see how exposed the fuel rods are.

It would probably blow it's top just like #1.

He said the fuel rods could be 'deformed but not meltdown'.

I believe TimeOutTokyo is talking about this report:

Radioactivity 400 times normal level observed in Miyagi: Tohoku Electric

Would it be logical to assume if radioactivity at a nuclear power plant is 400 times the normal level, that there is a leak somewhere at this different facilitiy?

This is exactly what I'm talking about.

They clarify later on that it's hydrogen like the first reactor, but you can't just release statements like that with nothing else and have it not freak people out. Maybe some of it is getting lost in translation (given their populations' background in english that seems like a pretty ridiculous thing to happen) but they really need to be more specific about what is going on.

0638: The Japanese government is warning of the risk of another reactor explosion at the Fukushima plant - AFP.

Finally, maybe they should consider just evacuating around all the plants in the quake zone...with #3 having major issues this is really getting absurd.

No idea, have not seen any reports other than that one. The same twitter account posted this:

"The spokesperson says the radiation level has gone up at Onagawa Nuclear Plant, but it's now stable. They don't appear too concerned."

A second explosion could take place at a nuclear power plant in quake-hit Japan, amid fears of a meltdown and after the evacuation of 200,000 people.

Officials warned of the blast at the Fukushima plant's reactor three, but insisted it could withstand it as reactor one did on Saturday.

The first explosion destroyed the building housing the reactor, but did not prompt a major radiation leak.

Authorities have also been playing down fears of a meltdown but problems with reactor three's cooling systems have persisted.

I'm so confused. Why is there a reactor with abnormal radiation levels that's not even part of this facility and why aren't they talking about it. Too much is going on and the release of information has been erratic at best.

I think it's just very poor journalism or sensationalism. Take this headline for example:

Japan Spokesman Warns Of Fresh Nuclear Blast Risk

Koyodo:

http://english.kyodonews.jp/news/2011/03/77339.html

*Meanwhile, radiation monitored at the Onagawa nuclear power plant in Miyagi Prefecture on the Pacific coast shot up on Sunday, Tohoku Electric Power Co. said, adding that it was likely caused by radioactive substances let out at the troubled Fukushima No. 1 nuclear power plant in Fukushima Prefecture.Radiation levels were very low but about 400 times as high as in normal times, the power supplier said, dismissing the possibility that the Miyagi plant was to blame.
