Sounds like it's one plant. The cooling system is failing and that could cause a meltdown, but they haven't gone to their emergency cooling system yet. Things could change.

http://www.foxnews.com/world/2011/03/11/japan-issues-emergency-nuke-plant-leak/

It's not leaking radiation, per se. They are purposely releasing slightly radioactive vapor to lower the pressure to protect it from a possible meltdown, so the area immediately around the plant has higher levels of radiation.

It's all pretty confusing, but it doesn't appear a disaster is imminent. Now, if they go to the emergency cooling system and that fails, then shit will hit the fan.

well, this was a really massive earthquake, but i've also been wondering how this will affect the whole nuclear shift. this was a freak event. the massive quake didn't mess it up, it was the massive tsunami the fucked things up, which is something we usually don't have to worry about in most of the US

there's definitely things that can be taken away from this, like if you're going to build a new plant on the shore line in a tsunami prome area, then maybe you should build a big dike around it, or enclose it in a giant waterproof dome

The way I understood it, the problems aren't linked to a tsunami hitting the building, but rather to the tsunami messing up the water supply that was used for cooling. The fact that it's one a shoreline now is more an advantage than a disadvantage, since they can use the seawater for cooling purposes now as an alternative.

http://www.washingtonpost.com/business/economy/at-two-reactors-a-race-to-contain-meltdowns/2011/03/13/ABtdVDU_story.html

Reasonable rundown of current nuclear situation. My question: are they flooding the interior containment unit (the one closest to the nuclear fuel, the vessel surrounded by steel) with seawater or are they pumping seawater AROUND that vessel, in an outer containment vessel?

Because steam forming (causing pressure which need to be vented) means water is boiling away, and if the water boiling away is around the fuel rods and that water cannot be replaced, then it would seem a meltdown, even more than the partial meltdown that was reported, is very close to a reality.

Yes, but that seems a theoretical risk right now. And if seawater can be continued to pump into the outside chamber, its sounds like those will be OK. What I would really like to know is if there are only a matter of hours before the water INSIDE the reactor chamber is boiled off.

One report I read said seawater used in the method they were employing would take ten days to bring temperatures down.

None of this amounts to "another Chernobyl." The Chernobyl reactor had two crucial design flaws. First, it used graphite (carbon) instead of water to "moderate" the neutrons, which makes possible the nuclear reaction. The graphite caught fire in April 1986 and burned for four days. Water does not catch fire.

Second, Chernobyl had no containment structure. When the graphite caught fire, it spouted a plume of radioactive smoke that spread across the globe. A containment structure would have both smothered the fire and contained the radioactivity.

If a meltdown does occur in Japan, it will be a disaster for the Tokyo Electric Power Company but not for the general public. Whatever steam releases occur will have a negligible impact. Researchers have spent 30 years trying to find health effects from the steam releases at Three Mile Island and have come up with nothing. With all the death, devastation and disease now threatening tens of thousands in Japan, it is trivializing and almost obscene to spend so much time worrying about damage to a nuclear reactor.

What the Japanese earthquake has proved is that even the oldest containment structures can withstand the impact of one of the largest earthquakes in recorded history.

HarveyWallbangers

Things could change obviously, but there are safeguards for the Japanese nuclear power plants that weren't there for Chernobyl.

http://www.nytimes.com/2011/03/14/world/asia/14health.html?_r=3&ref=science


Although several plant workers are ill from radioactive exposure in Japan, the radiation risk to the public appears low so far, experts said.

“At least as of now, what we’re looking at is rather more like Three Mile Island than Chernobyl,” said Dr. David J. Brenner, director of the Center for Radiological Research at Columbia University.

The radiation release from the 1986 Chernobyl disaster, where the entire reactor blew up and vaporized its radioactive fuel, was about a million times the amount released from the partial core meltdown at Three Mile Island in 1979, he said. The Chernobyl accident led to an epidemic of thyroid cancer and increases in leukemia, he said.

But from Three Mile Island, Dr. Brenner said, “There is no evidence that anybody at all got sick, even decades later.”

i don't think it was the water supply, its the pumping system that recirculates the water and keeps it cool. the pumps run of the regular energy that the plant supplies, they shut that down after the quake. then they went to the backup diesel generators to run the pumps, those were knocked out by the tsunami. they had a 3rd backup, batteries, but those only had a life of 8 hours.

my thinking is that in the future they should put those diesel generators way the hell up in some tower, so they are far away from any flooding risk. if those diesel generators had survived none of this would have happened i think

That's exactly the kind of engineering design type stuff you learn in a disaster like this.

Though generators in a tower might be more susceptible to hurricanes and tornadoes. Maybe you need 2 sets of generators.

Except that your excerpt fails to account for the melted fuel rods descending into the ground. Where radiation will be more problematic, localized and severe than steam.

Chernobyl, if I recall correctly, was an experimental design. This design is old and highly tested. Three Mile Island had a partial meltdown where partially liquefied fuel material collected in the bottom of the containment structure. A full meltdown, might compromise that structure more than occurred Three Mile Island.

And its worth noting that two of the external containment structures have already been damaged by explosions, so they are already partially compromised in the event of more steam release.

Reactor #2 now has a fully exposed core and the pump system failed. They are working to restore presently.

EDIT: I am way behind. NYTimes has Tokyo Electric saying that they got seawater back in. Fuel rods were exposed for several hours.

People within a 20 km radius of the reactors are being told to stay indoors with a/c and ventilation off.

Dental X-Ray indeed (from Times story above), but still basically good news:


By Monday night, officials said that radiation readings around the plant reached 3,130 micro Sievert, the highest yet detected at the Daiichi facility since the quake and six times the legal limit. Radiation levels of that magnitude are considered elevated, but they are much lower than would be the case if one of the container vessels had been compromised.

3rd explosion reported, Reactor 2, now they are three for three. This link makes a leap to worse than Three Mile Island, but its unclear how they confirmed a total meltdown other than a comment that it was impossible to rule it out. Haven't seen word whether the explosion was expected as part of a pressure release. Also unsure if water is still getting to the fuel rods.

http://www.telegraph.co.uk/news/worldnews/asia/japan/8382139/Japan-crisis-third-explosion-raises-spectre-of-nuclear-nightmare.html

Water is being pumped in to No. 2, lending plausible that the steam release and subsequent explosion were planned.

That's exactly the kind of engineering design type stuff you learn in a disaster like this.

Though generators in a tower might be more susceptible to hurricanes and tornadoes. Maybe you need 2 sets of generators.


These are 40 year old reactors built with 50 year old technology. Current state of the art doesn't require pumps in the backup cooling systems. Cooling is based on convection flow, so will keep circulating without any source of external power at all.

Outstanding.

They've proposed a nuke plant here in UT.

I thought they could have a relatively safe "meltdown" as long as the containment facility wasn't breached.

Well, that is a matter of some conjecture. Chernobyl was entirely different and Three Mile Island has a partial meltdown. A full meltdown, fuels rods and control rods liquefied, burn very hot without cooling. Harv's article pointed out that a normally functioning reactor operates just over 500 degrees. But an uncooled one can get well past 1000.

A liquefied fuel source could, under the right conditions, get even hotter as the control rods would likely not be as effective once the pellets melt. It would still take a tremendous amount of energy to get through the main containment fixture (made of steel and concrete), but its theoretically possible. No one has tested the possibility live before. The good news is that it seems all three reactors are still being fed seawater (a technique called feed and bleed).

There Mile Island had a shorter period of time with one reactor with exposed fuel, suffered a partial meltdown and was found to have some fuel collected at the bottom of the containment structure.

If the main containment structure hasn't been compromised (and radiation levels seem to indicate it hasn't) they stand a far better chance.

I thought they'd conceded the meltdown a while ago now. Breach of containment would be the only really bad surprise at this point.

But I'm not following it that closely.

They conceded that a partial meltdown had probably happened. But there was no way to be sure.

However, bad news on the containment front. The last explosion has been discovered to have damaged the main steel containment structure of Reactor 2. They are evacuating the site.

Not a bad read for the basics:

http://allthingsnuclear.org/

Worrisome point: Reactor 3 has MOX fuel, which is recycled Uranium Oxide plus Plutonium. Plutonium and its heavier cousins are far more lethal in the radioactivity released than uranium. If workers need to leave the entire facility, the Reactor 3 sea water operations would stop. If the MOX melts, its the most dangerous should any radioactivity from it be released. Only a percentage of the fuel in 3 is MOX though.

The number 4 reactor building fire caused radiation to spike, but readings have come back down. Quoted one expert that they should know something about whether the containment vessel at 2 will hold in the next 24 hours.

Numbers five and six are having pump problems, but have cooled significantly in the meantime. I think it takes on the order of 10 days of cooling to move the reactor to a safe point. Still, according to their sources, a complete failure of cooling and then the worst case scenario are still unlikely.

Regarding the remaining 50 workers at the plant:

"Their situation is not great," said David Brenner, director of the Center for Radiological Research at Columbia University in reference to the remaining workers. "It's pretty clear that they will be getting very high doses of radiation. There's certainly the potential for lethal doses of radiation. They know it, and I think you have to call these people heroes."

its amazing their dedication to country. have you heard any stories of looting and shooting? nope.

I was just listening to a radio story about the same thing. In the USA you would see people looting big screen TVs amongst the ruin....not in Japan.
