Reactor meltdown possible in Japan.


Recommended Posts

I have not heard anything about a leak in #3. Not sure where you got that information. The water was simply boiling off and being released via the steam vents until the building exploded due to hydrogen buildup.. There is no system to circulate the water so it's just boiling off as they put it in.

#2 had a stuck steam vent, but it is now unstuck and they have been resuming the sea water injection.

"At 1:10 a.m. Tuesday, TEPCO opened some steam valves and resumed work to pump seawater and is considering opening more valves, according to the company."

You cut this part

With radiation levels around the facility risen, TEPCO is suspecting the reactor cores have partially melted, a critical nuclear safety situation.

Not pertinent since we've suspected that the cores have partially melted since Saturday night.

Really, your posts Sat were not that but I digress, we were only talking about one situation Sat. Now reports of fully exposed rods, I do not believe anyone knows what the final outcome, all suppositions but when the people running the show say suspects it shows uncertainty.

Yep and...

BREAKING NEWS: Suppression pool may have been damaged at No. 2 reactor: gov't agency (08:07)

Did they just say that the operators have been evacuated? Or was that a mistranslation? This analyst guy on NHK is really pessimistic about this news.

yeah, they evacuated the operators. (The guy on NHK says this may be the worst case for Japan reactors.)

Oh?

Thank god.

FYI, NHK says that there was indeed a partial meltdown in reactor #1.

:whistle:

If indeed this is "the worst case scenario", (and, believe me, I'm not generally one to be an "alarmist") but we should start monitoring the mid and upper level winds going forward:

Significant Chernobyl contamination only extended 1,000 miles.

NHK translation is saying something about radiation levels are 10,000 times more then normal?

Ugh. I'm sick of hearing the amount of radiation leaking out getting compared to "normal". Statements like that are almost purely to generate hype and make headlines more attractive. I'm by no means an expert and I don't know how dangerous "10,000 times more then normal" is, but neither does the rest of the general public and news stations are taking advantage of this.

Agreed.

From the scraps I've gathered, "normal" is about 1 microsievert. From Wiki, you generally need about 1 sievert to start making people significantly sick. 10,000 times "normal" would be 0.01 sieverts. Getting up there, but still not "deadly" amounts of radiation by any means.

vents were closed....batteries failed....did not allow them to open for a while....batteries were replaced....vents opened......could not pump water until pressure is reduced....when they did...water levels could not be maintained....core exposed....partially....at the very least.

No 2 seems to be in big trouble.

What is the status on No 1 and No 3? Did they begin to melt....sea water to flood chamber.....heat caused the gases...then explosion while venting....but chamber held as the cores were cooled.....no breach?

Batteries failed. Isn't that the third thing that went wrong?-

-power cut off

-back up pumps tsunamied

-back up batteries fail/insufficient.

How many damn problems in life end up coming from failed/not enough batteries. How could they not have enough on hand?

*and what is this 'explosive impact' stuff that they are babbling about on CNN now? I know there was another explosion of some time about two hours ago now....any news on it anyone?

-and thanks to whomever it was that posted the aerial pic.

Miss that art guy as well on this thread.
