Radiation Levels Surge Outside Two Nuclear Plants in Japan
Foxnews.com ^ | 3/11/11

Posted on 03/11/2011 4:36:55 PM PST by socialism_stinX

TOKYO – Japan declared states of emergency for five nuclear reactors at two power plants after the units lost cooling ability in the aftermath of Friday's powerful earthquake. Thousands of residents were evacuated as workers struggled to get the reactors under control to prevent meltdowns.

My goodness if these reactors go the tsunami will be nothing compared to the devastation these plants could cause. Is the radiation at lethal doses yet inside th reactors? I hear its like 1000 times above normal and climbing.

Kakizaki said officials have confirmed that the emergency cooling system -- the last-ditch cooling measure to prevent the reactor from the meltdown -- is intact and could kick in if needed.

"That's as a last resort, and we have not reached that stage yet," Kakizaki added.

I can't imagine this getting any worse, I have never seen such devastation as this.

And now it seems that it might be hitting the fan at these nuke plants. The Japanese have been good friends for 60 years...it is heartbreaking.

The videos coming out of Japan of the destruction are horrifying and frightening.

Whole towns destroyed or swept away.

Thousands dead and missing.

A natural disaster and a human tragedy.

I didn't think a reactor problem would take 12+ hours to develop.

I really only understand enough about this technology...

but did this problem happen when the earthquake struck and they are only now trickling out information about the seriousness of the situation?

The reactor cores won’t melt down completely. They have emergency cooling systems. But this is a major test for the Japanese nuclear engineers. The article doesn’t say where radiation is 1000X above normal in the plant. Most likely, that is not where people are working and workers are probably heavily shielded from radiation. I’m sure thorough consideration was given to earthquakes when they designed these plants, especially considering the plants are in Japan.

These are very precautionary evacuations and if there was a chance of a Japanese version of the China Syndrome, they would be evacuating a lot more area than just 10 miles around these plants.

Think about Chernobyl. The reason it continues to be so horrible is that there was absolutely no containment around the reactor, so when it blew it spewed directly into the atmosphere for weeks until they could snuff it.

The Japanese nuclear generation plants are state of the art with many backup systems to prevent a major accident; and I define “major” as being on the level of a Chernobyl. They are not even close anywhere in Japan.

The pictures of those cities where all you could see were foundations...and where entire parts of cities had subsided and the water just sits there. Yes, this is a human tragedy on an unbelievable scale...even before these nuke plants get involved.

The terror the survivors must have felt last night, just trying to survive through the night.

I agree that there’s not going to be a full core meltdown. But if the backup cooling systems were damaged by the quake, that could greatly complicate the situation. It’s odd that radiation levels outside the plant are reportedly 8X normal levels. That probably means some radioactive steam has already been vented out of the plant. But overall I’m confident that these plants were designed to get through a huge earthquake list this one without a major disaster.

In modern plants when the core melts it will melt the steel and concrete around it. When this happens the uranium is no longer as pure and thus the reaction slows down to the point where the mixture hardens. This is all suppose to happen within the containment building and not cause any build up of pressure which could cause an explosion.

From the Los Angeles Times

The coolant water's temperature had reached boiling temperature, the agency reported, citing the power plant's operator, Tokyo Electric Power.

...

Authorities have ordered the evacuation of all civilians in a two-mile radius around the No.1 plant, a total of about 3,000 people, and planned to vent slightly radioactive steam from the plant, located about 160 miles north of Tokyo.

TOKYO | Fri Mar 11, 2011 5:14pm EST

Radiation detected at a central control unit at Tokyo Electric Power Co's No.1 reactor at Fukushima Daiichi plant is not at a level that would require workers at the plant to evacuate, a trade ministry official said on Saturday.

The radiation at the control unit has risen to about 1,000 times the normal level, the official said..--Reporting by Osamu Tsukimori

The MSM is good at sensationalizing. Fear is a powerful tool.

Yes, this is tragic..BUT I have faith in Japan, as they are well aware they are in a high stress location, thus they build on their real estate accordingly. I am sure they know what they are doing with backups for backups. The Anti-nuke-energy crowd will play off this and are.

"The United States has transported coolant to a Japanese nuclear plant affected by a massive earthquake and will continue to assist Japan, Secretary of State Hillary Clinton said on Friday. "We just had our Air Force assets in Japan transport some really important coolant to one of the nuclear plants," Clinton said at a meeting of the President's Export Council.

"You know Japan is very reliant on nuclear power and they have very high engineering standards but one of their plants came under a lot of stress with the earthquake and didn't have enough coolant," Clinton said

Can they dump a bunch of graphite control rods into the reactor core and shut it down that way? Or have they already tried that by now? Just wondering.

I hope this is a repeat of the hysteria over Cassini’s one in a million chance of reentry during the flyby. People were having kittens. My dad built the the thing and described the containment on the propulsion system. It was pure fearmongering.

If the normal level is essentially zero, then 1000X normal could still be close to zero and safe. It’s also a question of where in the plant the radiation is 1000X normal...hopefully not where people are working.

I found:

"I'm sitting in a power plant right now. Power plants don't use coolent other than water. It sounds like the Feed Water pumps aren't running at capacity because they are on battery power. The only way to cool the reactor is to get the feed water pumps running. Or some how put portable one on line but ive never heard of that being down before. comment by chunga at 3/11/2011 11:53:25 PM6:53 PM ..boric acid or boron infused water can be used as a coolant."

"The U.S. Military did not deliver water to the Japanese. Someone did not prepare Secretary Clinton to speak, and made her look foolish. The U.S. has delivered generators to the power plant to provide power to the COOLING PUMPS. That will aid in cooling the reactor."

“The Japanese nuclear generation plants are state of the art...”

Yes, and that is a problem for us. Our plants are 1970s technology or earlier. If this can happen to their “state of the art” plants, think of what an 8.9 quake here could do.

Read the safety reports from some of our plants and you won’t get much sleep. I saw a report online about a plant within 80 miles of me, and it wasn’t comforting in the least.

Ev I took as only showing sarcasm in the MSM reporting, not making fun of the Tsunami/Japan or her citizens.

You have heard of sensationalism within the MSM media, correct? They lack facts so they just run with it..historically speaking.

Have faith in Japan's engineers. They may not need as much help from the US government as our government would like you to think. Japan is not Haiti.

Not to sound callous but if they’re only evacuating a 2M radius this is under control. Serious, but within containment.

Prayers up nonetheless.

The following is supposedly from a commentor on a CNN article. I grabbed it from here Japan Quake: Fukushima Reactor Must Be Shut Down, Core Cooled but couldn't actually find it at the CNN article but there were hundreds:

---------

 I’ve worked in the US nuclear industry for 30+ years and for 18 years I was a licensed senior reactor operator/control room supervisor on a boiling water reactor (BWR) similar to the Fukushima plant. I helped write the emergency procedure guidelines that are used at US BWRs. There is a great deal of information flying around that just does not make sense. There just seems to be no detailed technical information getting out to the public on this. At the risk of over simplifying the system, a BWR is like a giant pot of boiling water. Regular light water, not heavy water, goes through the reactor, is heated by the splitting of uranium atoms, turns to steam and spins a turbine-generator to make electricity. The steam is condensed back to water and pumped back into the reactor to continue the cycle.

There are 3 basic barriers to the release of radiation: the metal clad that encases the uranium fuel, the reactor pressure vessel, and the containment. If 2 of these 3 are compromised, and the third is in jeopardy, US plants will advise shelter or evacuation of nearby residents.

The reactor operates at a normal pressure of about 1000 psig. During an earthquake of this magnitude, the reactor would be expected to automatically shut down (called a reactor scram). Control rods are hydraulically driven into the core in less than 7 seconds. I do not know if this took place but if it did not, we’d probably hear about it because it would be such a big deal. Even with rods inserted, the reactor continues to produce heat equivalent to about 3% of its full power level. This is not the same as taking a pot off the stove and letting it cool. There are still some atoms splitting and fission products decaying that produce heat. This drops off slowly and is why there needs to be layers of redundant cooling with backup power. During such an earthquake, power from outside the plant would not be expected to be available.

The plants have several back up diesel generators (locomotive style engines) that supply power to motor driven cooling systems that will supply high flow of water up to about 300 psig.. There are also steam driven systems to supply cooling water up to 1100 psig. There are also pressure relief systems that active at about 1100 psig. If reactor pressure gets too high, relief valves open and discharge steam to a water filled pool inside the containment.

Here are some information being reported that does not make sense. Reports that the pressure is 1.5 times normal; incorrect. There are at least 10 relief valves and any one can handle the energy after a plant shut down. CNN reports the US military has flown coolant to the site, but the coolant they use is regular water; I can’t imagine why the US would need to fly in coolant.


Right now I’d want to know a few things.


Are all rods fully inserted? What is the water level in the reactor? It’s normally about 12 feet above the top of the fuel. What injection systems are available? What is the reactor pressure? What is the status of containment?


Based on limited information, this is what I think might happen:


Earthquake hits, high vibration on the main turbine automatically trips the turbine by rapidly closing stop valves. Reactor automatically shuts down (scrams) all rods go in. Earthquake disrupts off site power to the plant and back up diesel generators should have started, maybe they did not. Main sources of water to the reactor are not available. If there is no pipe break off of the reactor, the pressure will slowly increase. After about an hour, a relief valve(1 of about 10) will open at about 1100 psig and drop pressure to about 1080. The steam is sent to a pool of water called a suppression pool in the containment that condenses the steam. This valve will cycle open and close every 5-10 minutes. Operators would use a small steam driven turbine (RCIC) to supply water at high pressure to the reactor under these circumstances for several hours. You can sit like this a long time, hot and at 1000 psig it’s no big deal as long as water covers the fuel in the reactor pressure vessel. If that turbine is not available, there is a larger steam driven turbine (HPCI) that supplies more water meant to provide make up if there was a pipe break.

If neither of these systems is available, the relief valve will continue to cycle and reactor water level will slowly drop. At some point before the water level lowers to the point of uncovering the fuel, all the relief valves would be open (ADS) and pressure would be reduced to below 300 psig to allow the low pressure but high flow systems (CS & LPCI) to restore water level and cooling. These pumps however, need electricity, like from the diesel generators, to run. If things get this far but there is no injection, in US plants there are things like diesel fire pumps that can be tied in to provide alternate sources of water. I’m not sure if they are set up to do this in Japan. Without cooling, eventually the fuel temperature will exceed 2200 deg F and the clad will melt. Fission products that are highly radioactive will get dispersed into the reactor vessel. If there is a pipe break or relief valve open, those fission fragments get dispersed through containment.
