BREAKING NEWS: Hydrogen explosion occurs at Fukushima No. 4 reactor (11:53)
What does this mean? How serious is this explosion?
This is where the spent fuel is stored. Lots of it.
It’s so serious that Godzilla has fled Japan.
Think it matters where it took place apparently the prev explosions were all outside the containment and the radiation impact was minimal.
It’s very hard to evaluate this whole situation the media is hyping the end of the World, some experts are saying not much can happen so long as the containment vessel remains intact.
Just a question. How many reactors does this location have? Indian Point has 3 and Connecticut Yankee, before it was decommissioned , had 3.
As I understand it, the building was used for storing used fuel rods in big vats of water. If something caused that water level to drop, the rods could heat up, and the zirconium cladding on the rods could react with water, releasing hydrogen. Apparently there was enough hydrogen/air mix trapped in the building to cause an explosion.
Most likely, the fuel in the reactor (if any) was not involved...
Dumb question: is this ONE nuke plant with several reactors or ...?
I believe the whole plant has 10 reactors.
I’m starting to get the feeling that locating a half-dozen nuclear reactors in the same compound, within sight of the Pacific Ocean, on the boundary between two tectonic plates, is a design concept with a set of drawbacks that may outweigh its advantages.
It’s serious. Short term exposure to the levels of radiation can cause damage. They are now talking milliseverts instead of microseverts. That is why they are evacuating a 20 kilometer area. Those in the 30kilometer area are told to stay indoors.
There is some things not being explained about timing and others are wondering if the radiation is actually coming from another reactor. They have already admitted there is a defect in the containment in reactor 2.
Well one doesn’t know what all that shaking did to all of the above. Perhaps something moved or failed from the quake and is finally reaching a critical point.
OMG..bad, bad, bad.
How do you evacuate all of Japan?
CNN just said there are reports of a fire at reactor #4
Show of hands...how many of us know what the hell we’re talking about, as in we are actual nuclear scientists, and how many are at the mercy of the chicken-little press?
I’m in the latter camp. :-D
Multiple threads, SE Mom ... fire at reactor #4?
A thought for Hannity’s panel. Get a guy in a Godzilla Suit ~
Part of Japanese culture is to not admit that there problems. The power company may be having an issue being clear on what is going on.
Mercy of Chicken Little Press camp here—same camp I was in after the oil spill.
A little bit of each. We do have nuclear physicists who post here, but I haven’t seen any of them lately.
You can watch the live English-language Japanese news broadcast here:
They’re recapping the events of the last 12 hours. You’ll need a scorecard to keep track of what’s happening in each reactor, though!
Japan has already thrown in the towel and called out for any and all help. Seems nuke experts knew that already when pumping seawater via a firetruck was the only option to use as coolant.
Can’t say much for the working environment for all the volunteers who say this is just a couple times worse than exposure when eating a thousand bananas.
Saltwater is very corrosive by itself but add heat, pressure and exotic metals and the process speeds up. So, things better cool down soon or the worst case scenarios begin. Contaminated means radioactive in this case and the answers to what type and life of contamination will tell you how long you can survive working in such a contaminated environment before having to walk away from it...far, far, away.
Im in the latter camp. :-D
Exactly. Even those of us who know something about radiation don't have enough information to go on. An explosion is bad. But as to specifics on the radioactivity involved--I don't know.
Nuclear energy has been portrayed by some as the worst, most dangerous thing ever. If airplanes were held to the same safety standard, we'd still be taking ocean liners.
Update just came across that the fire has been put out.
I figure it’s already bad for people near there. However, I’m wondering how bad this is going to be, and if any fallout is coming to California (where I live), and what impact would fallout in California have.
If there is a bad explosion that releases lots of radioactive material, will it dissapate in the atmosphere by the time it hits here or not.
CNN won’t need any studio lights when Sanjay, Anderson, and Soledad return to the US.
Cut out the Godzilla crap already. It was old before last week, and the danger & devastation is real and current.
Yep- very hard to keep up isn’t it?
Fire at reactor 4- and serious stuff at 2..possible crack/breach or whatever the correct term is...
Believe it or not- one of the best places I found for ongoing news is a live Reuters chat:
And I listen to NHK here:
Right now the newsreader is giving all kinds of warnings- bring your laundry inside- don’t go outside, don’t use your heat/ac to ventilate house.
BTW- I just noticed an odd picture on Drudge- in the place where he usually has tsunami or eathquake or nuke plant pics- he has a photo of a Japanese woman holding flowers- I don’t understand the significance or meaning.
The Japanese people are now being told what specific high radiation doses will cause. For example - Temporary infertility, etc..
I had friends in college that majored in Nuclear Engineering. I really wish I was facebook friends with them so I could ask them all sorts of questions. I feel very ignorant right now, and I really don’t trust the mainstream media.
The interesting thing to watch right now is that the higher dosage of radiation is around the #3 reactor and that is the one that has the MOX fuel.
think weapons grade plutonium used to make fuel.
Might just have gotten tired of leading all the bad news.
Japan’s prime minister warns that radioactive levels have become high around an earthquake-stricken nuclear power plant after explosions at two reactors, adding that the risk of more radioactive leakage is rising. www.reuters.com
There is no place for the usual FR dark humor in this horrific tragedy.
I lived in Japan and grew to love the Nihonjin. Those are my friends who are hurting.
'Tain't funny, McGee...
Read that #2 has Plutonium. And Japanese officials think it may have a breach.
Anyone see the jackass mouthpiece for the nuclear industry on HANITY tonight?
Said nobody died from Chernobyl exposure or was injured from the fallout.
Complete lying mouthpiece.
Then Greta comes on and gives the announcement of the explosion and fire and everyone told to stay inside w/i a 17 mile radius.
Wish that guy’s family lived nearby since he thinks there’s no danger.
I think it refers to the headline just above it and to the left:
"PM Kan asks public to act calmly..."
From Reuters live feed quoting NY times: A 1997 study by the Brookhaven National Laboratory on Long Island described a worst-case disaster from uncovered spent fuel in a reactor cooling pool. It estimated 100 quick deaths would occur within a range of 500 miles and 138,000 eventual deaths.
The study also found that land over 2,170 miles would be contaminated and damages would hit $546 billion.
That section of the Brookhaven study focused on boiling water reactors the kind at the heart of the Japanese crisis.
It’s hard to figure out who to trust when it comes to the information.
On one hand, you have the liberal anti-nuclear power people that all nuclear power is terrible and you should never build nuclear power plants. So they are alarmists about the situation.
On the other hand, you have the people that say this situation is totally under control and no risks at all.
Obviously, it’s not totally under control and it doesn’t seem like there is a good plan for getting it under control.
Yeah- I saw him. I’m all for pro and con- I want to know both sides- but that guy was plain irresponsible.
And here’s what I see a lot of on varioius blogs and tweets:
0324: Helen Creak, who works for the Japan Exchange and Teaching (JET) programme in Yamagata prefecture, tells the BBC: “It is difficult to make rational decisions when we aren’t getting honest and accurate information from the Japanese officials or news stations.”
Also from BBC: 0337: A low level radioactive wind could reach Tokyo in 10 hours, Reuters is quoting the French embassy in the Japanese capital as saying.
Well..... airline crashes don't cause cancer or contaminate large areas....
From Rueters live feed: BREAKING NEWS: Small amounts of radioactive substances detected in Tokyo (12:37)
Though your present vocation is unclear, you should have been a nuclear designer.
