Not sure how the DOE and NRC have people "on site" in Japan, given the evacuations and whatnot. Heck, we didnt even let the Navy helos stay there, yet we have specialist boots on the ground? Something doesnt add up...

How about a few words instead of just a link?
The article 15 thing is scary.
The map linked to on the site is kind of neat, though I cant make heads and tails out of it...

OK then. Here is a link to an article about Japan envoking article 15.
Satisfied???

Doesn't have a translated page yet. Taiwan found passengers from Japan with above limit radiation level.

Nah, government is in charge now, so we know things will be OK...
Move along, nothing to see here....

As I understand, it prohibits everyone but the highest levels of government from issuing statements about the disaster. I guess it's intended to be a way of controlling hysteria and misinformation.
As with all such things, I'm sure we can count on it to cause the opposite problem (too little/inaccurate info) in the process. We shall see.

Kind of reminds me of the military recruiters during the Vietnam ddays saying, oh yes, u can get into any school the military has aafter bootcamp, rite,,lol It did not work that way.duh

I just have two crazy questions:
1) Who the heck had the brilliant idea about storing spent nuclear fuel over an active reactor?
2) OK they didn't have the diesel generators protected from the tsunami, but how long can it take for a skilled crew working 24/7 to get them going?

1) It is Japan, right? Home of the most expensive real estate on earth?
2) Im betting that the gensets got water in the oil and they ran until failure. I thought the initial reports stated that they ran for a little while and then stopped... or am I dreaming? That said, how long does it take to get some portable gensets in, even if they need to parallel up a bunch of small ones?

Strange designs in those reactors. Too bad it takes a tragedy for everyone to see the flaws. Now, the earthquake and tsunami may be the least of their worries. And, this is all happening in their winter time which compounds their misery. God bless those poor people.

They mentioned they were almost done bringing in new powerlines to the site to power the pumps.... but why not heli in some large diesel portable gens until the powerlines were finished? I'm sure there is a good reason? Its too easy.

There's 23 of them operating in the US too.

The Fukushima reactors are a "workhorse," or rather old nag, designed by General Electric, I believe?

Yes, GE design them.
I don't think it is as easily said than that. They probably try not to raise issue by starving off asking for help early on for diesel gen backup, or there were problems to begin with that they were trying to cover up.
My bet is on the cover up early on.

Any power station needs a set of battery and diesel back-ups to shut down safely in the event of going black...Coal needs around 3-4 days of aux power to avoid turbine bearing damage...Batteries are good for around 8 hours, diesels after the initial blackout is stabilised.
Nukes, with a significant need to get rid of copious heat for many days after a trip, so having aux power washed away/drowned doesn't do them any favours regardless of designer.

What happens if the remaining crew decides to evacuate and leave the power plant to care for itself? What then?
The question is if those efforts currently under way are not futile, or if they are merely a reflection of the refusal to give up.
TEPCO says there is a chance that a chain reaction and fission can occur:
Quote:
More remarkably, the Tokyo Electric Power Company (Tepco), which owns the power station, has warned: "The possibility of re-criticality is not zero".

I thought that was the case the other day when the whole shebang was evacuated...
Some places, they can order people in to throw bags of lead etc. and drop like flies on the way back to the line...My RSO can calculate the dose and request me to take a bag and throw it (at a pea sized source for x-raying tube welds)...
It's an interesting moral argument. Who gets to (most probably) die, and at whose orders, to protect many more from a potential ?
