OMG Earthquake?


Madness

We all pray for them, but.. this can get hell of a lot worse If they can't get control of their reactors.

It would be worse than Chernobyl and no doubt we would get the radioactive fallout over here.

Official: 2 Japanese plants struggling to cool radioactive material

okyo (CNN) -- Reactors at two Japanese power plants can no longer cool radioactive substances, a government official said Saturday, adding that a small leak had been detected at one of the facilities.

Atomic material has seeped out of one of the Fukushima Daiichi plant's five nuclear reactors, about 160 miles (260 kilometers) north of Tokyo, said Kazuo Kodama, a spokesman for Japan's nuclear regulatory agency.

Potentially dangerous problems in cooling radioactive material appear to have cropped up there, as well as at another of the Tokyo Electric Power Co. nuclear plants, Ichiro Fujisaki, Japan's ambassador to the United States, confirmed to CNN.

The Fukushima Daini and Fukushima Daiichi power plants are separate facilities located in different towns in northeastern Japan's Fukushima prefecture. Each one has its own set of individual nuclear reactors.

Kodama said the cooling system had failed at three of the four such units of the Daini plant.

Temperatures of the coolant water in that plant's reactors soared to above 100 degrees Celsius (212 degrees Fahrenheit), Japan's Kyodo News Agency reported, an indication that the cooling system wasn't working.

Authorities subsequently ordered residents within 3 kilometers of that facility to evacuate as "a precaution," Fujisaki said. That plant was also added to the Japanese nuclear agency's emergency list, along with the Daiichi plant.

Japan may have hours to prevent nuclear meltdown

(Reuters) - Japanese officials may only have hours to cool reactors that have been disabled by Friday's massive earthquake and tsunami or face a nuclear meltdown.

Tokyo Electric Power Co (TEPCO) (9501.T) is racing to cool down the reactor core after a highly unusual "station blackout" -- the total loss of power necessary to keep water circulating through the plant to prevent overheating.

Daiichi Units 1, 2 and 3 reactors shut down automatically at 2:46 p.m. local time due to the earthquake. But about an hour later, the on-site diesel back-up generators also shut, leaving the reactors without alternating current (AC) power.

That caused Tepco to declare an emergency and the government to evacuate thousands of people from near the plant. Such a blackout is "one of the most serious conditions that can affect a nuclear plant," according to experts at the Union of Concerned Scientists, a U.S. based nuclear watchdog group.

"If all AC power is lost, the options to cool the core are limited," the group warned.

TEPCO also said it has lost ability to control pressure at some of the reactors at its Daini plant nearby.

The reactors at Fukushima can operate without AC power because they are steam-driven and therefore do not require electric pumps, but the reactors do require direct current (DC) power from batteries for its valves and controls to function.

If battery power is depleted before AC power is restored, the plant would stop supplying water to the core and the cooling water level in the reactor core could drop.

RADIATION RELEASE

Officials are now considering releasing some radiation to relieve pressure in the containment at the Daiichi plant and are also considering releasing pressure at Daini, signs that difficulties are mounting. Such a release has only occurred once in U.S. history, at Three Mile Island.

"(It's) a sign that the Japanese are pulling out all the stops they can to prevent this accident from developing into a core melt and also prevent it from causing a breach of the containment (system) from the pressure that is building up inside the core because of excess heat," said Mark Hibbs, a nuclear expert at the Carnegie Endowment for International Peace.

While the restoration of power through additional generators should allow TEPCO to bring the situation back under control, left unchecked the coolant could boil off within hours. That would cause the core to overheat and damage the fuel, according to nuclear experts familiar with the Three Mile Island accident in Pennsylvania in 1979.

It could take hours more for the metal surrounding the ceramic uranium fuel pellets in the fuel rods to melt, which is what happened at Three Mile Island. That accident essentially frozen the nuclear industry for three decades.

Seven years later the industry suffered another blow after the Chernobyl plant in Ukraine exploded due to an uncontrolled power surge that damaged the reactor core, releasing a radioactive cloud that blanketed Europe.

The metal on the fuel rods would not melt until temperatures far exceed 1,000 degrees F. The ceramic uranium pellets would not melt until temperatures reached about 2,000 degrees F, nuclear experts said.

If it occurred, that would ultimately cause a meltdown, with the core becoming a molten mass that would melt through the steel reactor vessel, releasing a large amount of radioactivity into the containment building that surrounds the vessel, the Union of Concerned Scientists said.

The main purpose of the building -- an air tight steel or reinforced concrete structure with walls between four to eight feet thick -- is to keep radioactivity from being released into the environment.

While there has not been any indication of damage that would undermine the building's ability to contain the pressure and allow radioactivity to leak out, there is a danger that if pressure builds too much then the walls could be breached.

That is really, really bad. I'm scared. Not to mention the fact that the Juan de Fuca plate might move on our side because of the stress of the movement on their side.

If there is a meltdown I think it would be on the lines of Three Mile Island and not anything like Chernobyl. The real bad news is, the earthquake has already probably cost far more in damage than the $200-$300 billion than Chernobyl inflicted, which will be a huge burden on an already deeply troubled economy. This could be the beginning of the end of Japan as an economic power.

I admit that she might have a point somewhere, but it's not angels and demons, it's rather gravity. We know how such a small object like the moon can influence our lives (tide, biorythm, etc.), so why not say that there are certain changes in the gravity system of our planet when alignments take place? It could result in releasing friction at the edges of tectonic plates.

The force exerted on the earth by the comet is minuscule.

From what I gather, it is currently about 2AU, or about 3x10^11meters away from earth. I can't find the mass of of the specific comet, but I've seen numbers from 10^11 kg to 10^14 (halley's comet) from google.

Plugging into Newton's law of gravity F=G M1 M2/r^2, with G = 6 x 10^-11, mass of earth 6x10^24, the force of comet on earth=400N to 400,000N

For comparison an average male of 80kg exerts about 800N on the earth.

Are you going with the 'lucky guess' theory then?

What if the 'comet' was made of something really, really dense? She mentioned something about brown dwarf but I was not sure why at the time.

If you don't think the government keeps secrets, you should go off of your meds.

In keeping with the conspiracy, I'm hopeful influential governments will start releasing their UFO files in the not too distant future, as the shift towards more efficient energy takes place. But maybe I'm just too optimistic.

And the UFO's caused the earthquake, from one of their underwater bases, that the gubment knows of, but won't tell us!

By definition a comet is made out of rock and ice.

Where did I say any of that?

For the record, I in no way believe this earthquake is related to UFO activity. I do, however, believe there are classified UFO files. The New Zealand government recently declassified many of theirs.

This nuke reactor stuff is being hyped up wayyyyyy too much.

They only evacuated them like 2miles. if there was a real danger for a thermonuclear meltdown people would be moved much further... the explosion could reach very very far.

There isn't an explosion in a meltdown typically, and if there is, it's rather small, when the 'melted' nuclear fuel rods, breach their containment units and touch the bottom of the facility....that could, i say could....trigger a hydrogen explosion.....but nothing that would come close to damaging anything in the "very, very far" range. The real danger come from the release of radioactive material in the air and as it settles on land....and they're already thinking about doing that.

The 'meltdown' refers to the melting of the fuel rods. And radioactive gas that gets released is not very dramatic in its release.....but the consequences are dire to any living thing that comes in contact with it.

Actually, they upgraded the emergency level and increased the evacuation area to 10km. They're trying to control the pressure through ventilation. The primary objective is to get the cooling systems functional because they're relying on secondary cooling which isn't as effective.

Unlike Chernobyl, they are fully aware of the situation before it becomes an unstoppable reaction so there is a lower chance of it reaching meltdown.

Edit: Also, FYI, the term "meltdown" comes from when the fuel rods melt. The temperature is so high that when it comes into contact with vapors such as air or water, it explodes. The heat is a natural by-product of critical mass and the only way to stop the reaction is with a doping element such as enrich boron.

The danger comes from if fuel rods do melt, they burn at very high temperatures and are extremely difficult to put out. It burns so hot that sand actually melts into glass. The smoke and particles that come out are very radioactive and spread for thousands of kilometers in the atmosphere.

Actually, we'd be in trouble because the jet stream could carry the radioactive material towards us.

Good post, I agree with much of what you said.....and I also wanted to say, i'm hoping for the best for the Mrs and the kids.

However, I'm kinda iffy about your thinking that we'd be in danger of radioactive materials. The Polar Jetstream is at a higher lattitude, I think right now.....and may not be low enough to pass over Japan at this time of year. Also, the Jet streamis about 30k feet up above Japan....how much radioactive particulate finds itself up there depends on how much gets released, and its dispersal pattern, and if it even gets up that high to begin with, let alone travels that far. And it is a great distance, and it's certainly not a straight line to us. So, I'm kinda skeptical in how dangerous it really would be. Look at Chernobyl.....we didn't get any fallout here, from the jet stream that passes over Russia.

Just throwing that out there....not that I'm a Jetstreamologist.wink.gif

That's why it is in 'quotes.'

Just because it comes from the direction of the Oort cloud might not mean it is necessarily rock and ice, does it? Tyche has made me question a lot.

Then a woman predicts an earthquake on the Internet including magnitude. If not her explanation then what? I am open to ideas because I don't know what to make Of that.

This intelligent women/girl, has taken away everything of me about ever being skeptical. She is almost dead on on every video, and its kinda scaring me. She sounds crazy, but isn't. She just a very, very smart person with an IQ higher than Einsteins!

Watch this video, and according to her, this Tuesday, March 15h, everythings going to change.

Also, here's another interesting video of hers:

......Is it just me, or does she sound like a savior from the heavens to warn us all? huh.gif

Thats a pretty dumb thing for a "mod" to say

No, it's bloody accurate.

All the chicken littles in this thread need to go back on their meds...or at least back to school. I haven't seen this much nonsense since I left the God Thread.

Secret Gov't Conspiracies, Planets Aligning, Comets, Ufos's, Weird Feelings, etc

What the frack are some of you smoking???

And you call the mod dumb?? She's one of the only sane ones in this gathering of 'Lunatics Anonymous'.
