Japan hit by 9.0 earthquake.

Re: Japan hit by 8.9 earthquake.

^^ Yeah, a lot of the problem with nuclear power is lack of information (and propaganda). Also, people have the tendency to associate the word "nuclear" with "explosion." That was a very informative Post up there.
 
Re: Japan hit by 8.9 earthquake.

it is annoying hearing them talk like I'm going to come home a glowing radioactive mutant unless I'm on a plane tomorrow.

Dude, your avatar totally sells that post. :)

Still haven't heard from some friends in the Sendai area, and I'm starting to really worry about that.


before i went out i saw a tweet that they had reached part of sendai and at least part of it looked ok outside of some quake damage.
the devastation seemed more in towns i cant pronounce much less spell.

on the reactor..
there is no chance of chernobyl meltdown since it isnt a graphite reactor.,

and some reports (though several hours old) is the highest radiation was just prior to the explosion and has gone down since.
there were three civilians who were ex[posed then and are now being treated at a hopsital.

on my twitter feed iam following several reporters who heading to the area including the regional voice of america.

the only problem is they are limiting their communication due to fear of using up their batteries.

the issue with communication within some part os japan is some cell towers were damaged and everything is jammed.
though messages have better chance of getting through then voice.
 
Re: Japan hit by 8.9 earthquake.

Outside of experiments done in the 1950s there has never been a large-scale emergency at a BWR plant anywhere in the world. They have the proven track-record in that regard. Three Mile Island was PWR... that was a loss-of-coolant accident that caused a parital melt down.

Chernobyl had traits of both designs.

Most incidents occur at PWR plants because of the complexity of the system. British AGR plants have experienced isolated fuel melting due to refueling mishaps (Chaplecross)... and someone filled Hunterston Station with seawater by accident. :D In reality the British designs and the Canadian designs are far more fault tolerant than American designs... but that's a paper to be written another day.


So as serious as the situation is at Fukshima 1 it is also a fascinating situation as this is the first large-scale failure of a BWR.

Thank goodness I have plenty of popcorn! ;)
 
Re: Japan hit by 8.9 earthquake.

I'm hoping the Cascadia fault line doesn't join the party.

Yeah...the 1700 earthquake was really, really bad.

I'm hoping this doesn't ripple all the way to the New Madrid. Talk about an area totally unprepared to handle an earthquake as strong as what's hit it in the past...


:(


I was thinking about New Madrid, too. If a quake the magnitude of Japan's hit, it would be bye-bye St. Louis, Little Rock, Paducah KY, and there would likely be damage as far away as Chicago. :( Nothing short of catastrophic.

Yeah. Memphis and St. Louis don't exactly have construction up to Japan's earthquake codes.

Yeah...some of the suburbs in these areas may have better construction in certain places (some of these communities did at least start to pay attention to seismic bracing and things like that in the early 2000s), but the older construction will be demolished if the New Madrid ever goes off that badly again. I read a very scary book once that described the horror that could take place if ever Memphis and St. Louis had a serious earthquake. It would be absolute, apocalyptic devastation and I am not exaggerating.

Fascinating and extraordinarily helpful to have some clearly experienced input! Thank you for reg'ing and posting. :techman:

There is a nuclear plant near I live. Being a fireman I was given basic Nuclear Emergency Response training and later took more advanced training as it was offered. I am one of 4 people in the tri-county area authorized to enter the containment structure to perform man-down rescues. The plant has it's own team but they have to have a backup team in place... that's us.

On top of that I also took the Media Relations training when it was offered. They trained us to answer any questions that the media might ask and more importantly direct people to sources of information.

Then I have a father and two uncles who have worked in the nuclear industry... and they were Nuclear Navy before that... my mother worked at this plant as Health-Physics lab-worker until she had us kids.

...This kind of stuff is/was topical conversation around our table. I may not be a nuclear-engineer or even work there but I have learned enough over the last decade and a half to help alleviate some of the mystery and fear about these power plants.

Thank you very much for all of this. It's very good to have some word from a professional with some knowledge in this area.

the issue with communication within some part os japan is some cell towers were damaged and everything is jammed.
though messages have better chance of getting through then voice.

This is a very important thing for people to remember in case of a disaster, severe weather, etc.: a text message requires far less bandwidth and is more likely to get through than a voice call. These days, everyone--even those who do not like texting otherwise--should know and be able to text in case of emergency.



Now I am NOT sure of this, but has anyone heard anything about an 8.4 aftershock, or did I mishear something?

Maybe we can ship you off to Sendai with some KIO3 salt for that popcorn and you can watch close up


We're talking maybe a matter of six to 14 hours to core damage... possibly far less depending on the condition of the core. A fresh core would have less decay heat from secondary reactions where as a core in operation for 10 months or more would have much more decay heat.

They're saying they're reading cesium and I-131 in the atmosphere, so the core must be exposed.
 
Re: Japan hit by 8.9 earthquake.

My parents are panicking about this nuclear power plant thing and want me out of the country NOW. I am scheduled to go home in three weeks and my work contract goes for another two, and it is annoying hearing them talk like I'm going to come home a glowing radioactive mutant unless I'm on a plane tomorrow.

I hear ya. My parents are freaking out and getting on me to get in touch with my brother so he can continually reassure them that he's fine. I guess it's just, from a distance, the unknown seems scary.

I would love to be a fly on the wall right now.

They're saying they're reading cesium and I-131 in the atmosphere, so the core must be exposed.

If there has in fact been a hydrogen explosion then the core has most certainly been uncovered.

If they are correct and radiation levels are "dropping" that means they have established some type of water flow to the reactor. Water in addition to cooling the core also provides an additional layer of shielding.

It becomes a question now of long-term stability (at least a month to "absolute cold shutdown" and then cleanup when the levels decay far enough. That reactor is beyond repair at this point: Like TMI the engineers and scientists will be all over the place studying what went wrong and how the plant behaved... and they will incorporate the information into a backfit program. US plants will benignity from this information as it is developed.
 
Re: Japan hit by 8.9 earthquake.

You can get the amount of radiation in an hour that you are supposed to get in a year. Much is a relative term.

I'm not saying it's all flowers and sunshine, but considering the alternative, and the sheer magnitude of the quake, it really is remarkable and extremely reassuring that it's been contained to the extent it has.


The greater disaster in Japan is to some extent overshadowing the nuclear incident, and in this partially numbed state we're all in, we're perhaps not registering the nuclear incident as vividly as we would if it captured the media focus on its own merit.

I think it's a bit premature (and false) to judge the incident as remarkable and reassuring. We can't allow ourselves to be become complacent. An explosion and enough of a radiation leak to dispense iodine and clear a 20km radius is pretty major.

In the following weeks, we'll need to examine what specifically went wrong and why it has leaked at all.

Was the earthquake directly responsible for the problems? Or was it something consequential of the earthquake? If the latter, could those same conditions be triggered by something less dramatic than an earthquake?

Floods can be caused by a storm surge. If a plant needs an external electricity supply to operate cooling pumps, then could a storm or a lightning strike pose a risk too, as these things can bring down power supply lines.

We can take measures to make nuclear power safe, but no fail-safe is perfect, and from time to time across the globe we do have incidents and leaks when those fail-safes do fail. It's reasonable to think that the more reactors we have, the more frequent these incidents will occur.
 
Re: Japan hit by 8.9 earthquake.

I just read that the nuclear leak is being rated a 4 out of 7 on the scale they use for such things. Three Mile Island was rated a 5.

I gather that on this scale a 5 is 10 X more serious than a 4.
 
Re: Japan hit by 8.9 earthquake.

Damn, Goji, cut your parents some slack. My mom gets on my nerves as well, but there are potential nuclear meltdowns in your area. I'd cut Ma a little slack if I were in close proximity to the biggest earthquake in a nations history, a tsunami, and nuclear reactors with a fever. ;) Now if they asked you to bring them some snapshots from inside the plant, maybe you could take offense at that. :lol:

There was that episode of The West Wing where Alan Alda's character was pro-nuclear power plant (and Jimmy Smits' character was anti) and then one of them had an accident and suddenly it cost him the election. That was rather simplified and playing off of what people don't know.
 
Re: Japan hit by 8.9 earthquake.

Aftershock in the 6.4 range. I think I hear tsunami sirens going off in the background during a live shot of the Japanese coast. :(
 
Re: Japan hit by 8.9 earthquake.

Goji, I am really glad to hear you're safe. Please continue to be safe, and all my best to your friends and neighbors there in Japan.
I wholeheartedly second that, Goji. And three cheers for helping the children get through this terrible event. I've never been in an earthquake, but I'm certain I would have been one of the criers.

Re: Japan hit by 8.9 earthquake.

I really feel bad for them. This is horrible. But I will say this, they are very hard workers and will have their country up and running in no time.
 
Re: Japan hit by 8.9 earthquake.

I saw a report earlier that said the tsunami swept inland a distance of between 3 to 6 miles in the most affected regions.
