Re: The Japan Earthquake and Tsunami

This is undoubtedly a very dramatic situation. But panic won't help anyone and people thousands of miles away are freaking out more than the people living nearby. Even with two more meltdowns this will hopefully remain a catastrophe of local impact only. That's bad enough. Personally, I won't indulge in the scarier scenarios that are currently spread by the media.

Re: The Japan Earthquake and Tsunami

Anyway the latest news indicate that the situation at Fukushima is stabilizing. Reactor #1 is covered by several meters of sea water and the are able to feed cooling water to reactor #3. Latest radiation measurement is said to be only 50 µSv/hour and the wind is supposed to blow it out to sea for a couple more days. Doesn't look like reason for panic.

BTW where is the third meltdown? Neither BBC or my local news seem to report about any other than the two at Fukushima.

Not yet. But the cooling function of a third reactor failed.

Guardian articleTepco confirmed that the No. 3 reactor of the quake-hit Fukushima plant had lost its cooling functions. Yesterday a small amount of radiation leaked after similar problems hit the facility's No. 1 reactor.


This reactor might pose a bigger threat to the environment than Nr. 1 and 2 because it contains plutonium MOX. But that's me reading the news, I have no idea what plutonium MOX is.

Re: The Japan Earthquake and Tsunami

Miyagi Police Dept Chief said the death in the prefecture will exceed 10,000; 379 bodies are recovered as of noon

The BBC's Nick Ravenscroft in Sendai says fires are still burning in the waterfront neighbourhoods, mud and silt everywhere. But he says people are beginning to start a clean-up operation, distributing water and looking after the elderly. They're also putting up signs up to try to find out about people who are missing.


I've a lot of admiration for the attitude of the Japanese people.

The pic of the little boy being checked for radiation is just striking.

Radiation is raising again, likely due to the measures on reactor #3, where currently damp is left out of the casing to avoid an explosion.

Most experts believe that was the reason for the higher radiation measures around #1 yesterday as well. Cooling, however, failed as Japanese officials confirmed. Since seawater might react with the fission going on that's not at all good news.

I'm agreeing that it's no help to panic, not from our relatively save locations anyway, but it is a very serious situation. Should #1 blow up, because it can't be cooled or because the seawater reacts with the fission, radiation of the reactor will get into atmosphere uncontrolled. It's guessed that there's twenty as much radiation existing as in Chernobyl. So my main worry is still at reactor #1 right now. The area is already contaminated, should at least reactor #2, 3, 4 5 and 6 as those who have no cooling anymore not blow up too, the more of radiation due to damp is unfortunate and horrible but quite the lesser catastrophe.

However, as well in reactor #2 and #3 fissions seem to happen right now. There's nothing Japanese officials hide, it's just that nobody can say for sure right now. I wouldn't want to change with the workers who currently try to fix things in a contaminated environment, but I'm certainly glad that they try. I'm aware that the nuclear company Tepco often worked amazingly bad and was shown to neglect safety measures often enough - but the Japanese nuclear plants still are the safest of the world. Despite what my chancellor Merkel claims, most German nuclear power plants hadn't hold that much of damage even half as long.

ETA: While I'm writing Tepco is reporting that it's possible that reactor #3 will explode today, too.
ETA 2: The same time Japanese officials confirming a possible explosion. Greenpeace, however, is saying that it's likely that there is no fission going on in #3 right now.

You kind of scared me there, I was wondering what had happened to make such large atoms fuse

With such an enormous catastrophe, the fifth largest earthquake on record, it really is admirable how well they're handling the entire thing.

Re: The Japan Earthquake and Tsunami

The excerpt from an article below shows the explosion was caused by the plant operators trying to cool the containment vessel. This only proves just how desperate the situation is, when they knowingly risked an explosion to control the cooling. (Be sure to check-out youtube link at end of this post!)

This article also shows "the worst case" scenario of a total meltdown. And, it mentions that 5 reactors (now, at 6 on Sunday) are not cooling properly. This will go down as the most expensive nuclear accident in history, because so many nuclear reactors are going to be sacrificed to prevent total meltdowns. Just look for the use of Sea Water & boron (boric acid) & that will be a sacrificed reactor. (How are they going to shut down the chain reaction that is going on in Japan? One idea is to get a lot of boric acid into the bath. The element boron absorbs neutrons much better than U-235 does, so mixing boric acid into the vat will absorb the neutrons that make the sustain the chain reaction and shut it off.)

Article Excerpts:

Officials placed five reactors, including Units 1 and 3 at Dai-ichi, under states of emergency Friday after operators lost the ability to cool the reactors using usual procedures.

An additional reactor was added to the list early Sunday, for a total of six _ three at the Dai-ichi complex and three at another nearby complex. Local evacuations have been ordered at each location. Japan has a total of 55 reactors spread across 17 complexes nationwide.

Officials began venting radioactive steam at Fukushima Dai-ichi's Unit 1 to relieve pressure inside the reactor vessel, which houses the overheated uranium fuel.

Concerns escalated dramatically Saturday when that unit's containment building exploded.

Officials were aware that the steam contained hydrogen and were risking an explosion by venting it, acknowledged Shinji Kinjo, spokesman for the government's Nuclear and Industrial Safety Agency, but chose to do so because they needed to keep circulating cool water on the fuel rods to prevent a meltdown.

Officials insisted there was no significant radioactive leak after the explosion.

If a full-scale meltdown were to occur, experts interviewed by The Associated Press said melted fuel would eat through the bottom of the reactor vessel, then through the floor of the containment building. At that point, the uranium and dangerous byproducts would start escaping into the environment.

Eventually, the walls of the reactor vessel _ six inches (15 centimeters) of stainless steel _ would melt into a lava-like pile, slump into any remaining water on the floor, and potentially cause an explosion that would enhance the spread of radioactive contaminants.

If the reactor core became exposed to the outside, officials would likely began pouring cement and sand over the entire facility, as was done at the 1986 Chernobyl nuclear accident in the Ukraine, Peter Bradford, a former commissioner of the U.S. Nuclear Regulatory Commission, told reporters.

Another expert, physicist Ken Bergeron, told reporters that as a result of such a meltdown the surrounding land would be off-limits for a long time and "a lot of first responders would die."

Re: The Japan Earthquake and Tsunami

From what I heard, they are still experiencing after-shocks and are afraid of what other ( even minimal) explosions could take place.

Let's just hope everyone remains as safe as possible, and that everything works out as best as it can in regards to relief efforts. Thoughts and Prayers!

Re: The Japan Earthquake and Tsunami

That 2nd explosion posted above (see post 51 youtube video) is truly HUGE. Just as big as the first explosion, see post 15 or 50, which you can see in earlier posts I made in this thread. This is really serious, because these two explosions prove that the overheating is not controlled yet.

That's 2 nuclear power plants gone forever & will have to be closed permanently! This is very sad & potentially very dangerous until the cooling is under control & working.

Plus, I've now seen news reports that 'spent nuclear fuel' has been stored 'on top' of the nuclear reactor area. That's just plain freaky!

Is this true? It seems to be a really unsafe method of storage location???

I know some nuclear waste is cast in glass, but if this melts or explodes that could be a problem too. I just hope that the nuclear spent fuel was not stored in the reactor areas that exploded too, because that could be very serious radioactive material dispersed by the explosions. It's like a dirty nuclear bomb!!!

We need accurate answers about where the spent nuclear fuel has been stored, and if it is stored far away from the explosion areas??? Please research this & find answers if possible. Thanks!

This is going to be the ultimate test about nuclear reactor safety, because it is pushing all the safety redundancies past their design limits. We're into the FINAL fail-safe modes & these two (possibly up to 6) nuclear power plants are now destroyed permanently.

WOW, WOW, WOW... TOTAL DEVASTATION.

That picture of the forest totally wiped-out with every tree flattened and stripped like match sticks shows the killing power of that tsunami. No one would survive in most of those pictures.

This is very depressing what has happened to whole coastal regions on that side of Japan. Some communities must have been wiped off the face of the Earth, as if never there before.

I hope the USA will help our dear friends, yes the Japanese people, as much as is possible. Our nation & the world community should help now!

You can send money to the Red Cross for the Japanese people. The Red Cross can determine where the money is best spent more than we can know, and that is a safe donation that won't be lost or wasted, imo.

Re: The Japan Earthquake and Tsunami

I saw these satellite pictures in tv yesterday, but it's quite different to get more than a short glimpse on them. From first reports I thought it's more like Ishinomaki looks (what's horrible enough), but this full destruction is shocking. People didn't have the slightest chance.

Japanese officials claim not much radiation went out when #2 exploded. While 'not much' clearly is a relative measure and I'm still inclined to say officials do a rather transparent job, I'm by now more worried than during the weekend that we don't get as much information as we could. Or different said: Japanese people don't seem to get them. European TV interviewed the first returners last evening who all looked somewhat surprised how open the information is spread here and how open risks are discussed.

I really hope it was a honest call to stop the evacuation at 20 miles. More likely it's the only possible solution since the actual catastrophe destroyed too many streets and buildings.

Re: The Japan Earthquake and Tsunami

Since I've been here, this has been the most devestating thing I've lived through, in the sense that I'm seeing the aftermath of it. I'm in Yamagata, which isn't too far from where everything happened. We felt the earthquake, and lost power and water. So, for the most part, since I'm "inland", the Tsunami didn't affect me, only the quake did and I'm not far from Fukushima (where the reactors blew), but not close enough to have it affect even though, ironically, I was supposed to have gone there as opposed to Yamagata, but the BOE changed its mind, and I ended up in Yamagata instead. I'm upset over those who have lost their lives and how you can't turn on the news and stuff here without seeing families who have lost their homes. It's as sad as seeing Katrina victims, imo.

I don't know how they're going to do it, but I hope that they manage to recover somehow.

Yes, we are experiencing aftershocks. I'm getting them as I type this up. We had a strong aftershock earlier today...but not big enough to worry about here, but for Fukushima-ken...yeah, it is worrisome because of the nuclear plant.

I'm very glad you're ok, SSJ_Jup!

I have friends in Japan, one of them is currently tweeting almost 24/7 about everything she sees there, translates Japanese sources for us, answers questions, etc. Information technologies are a blessing in a situation like this one.

Re: The Japan Earthquake and Tsunami

Glad you're doing well, SSJ! The only 'direct' information I yet got was over friends of friends - the latter stayed in Japan for some time. I've heard the aftershocks, while they certainly disturb the rescue teams, aren't the worst experience for the people. Hard to imagine for a spoiled European kid like me.

I heard #2 lost as much cooling water as to become critical towards another fission now too. This reads so much like a bad dream, seeing how any measure doesn't work and things keep falling off. On the other hand, workers must do an amazing job to keep things in check as much as they do now. This could have been worse already, but there often seems to be time to help people and get the next measure in.

Re: The Japan Earthquake and Tsunami

Questions about a meltdown are totally justified. But the current radiation leaks look, to me, to be more hazardous than they were originally reported to be. The fact that US carriers are reading radiation levels 100 miles off shore what does that say about the intensity of the radiation on the mainland?
