A favorite of mine. The Wind in the Willows.

Or, for those finding that taste of mine somewhat childish. Three Men in a Boat by Jerome K. Jerome  A serious philosophical tractate over the futility of, well, ah, everything? You better read it, and get yourself prepared.

They are both about rivers and boats :)

It's very bad news, the Tsunami in Japan, and as they have fifty five nuclear reactor plants, and as every nuclear power plant have several reactors, I've heard numbers of over 150 reactors, all in all? Anyway, they will definitely  have to take a new look on their security measures. Not that the security they had was bad. Three systems after each other failed to do their job for different reasons. But they live more or less on a volcano, one of the reasons I've heard for why their traditional building technique was so ethereal and light was the risk of earthquakes, The houses was easy to rebuild. Nowadays we go the other way and try to make them as safe as we can instead. But with a earthquake erupting as that one, being of a 8.9-magnitude and with the following tsunami striking northeastern Japan you can never be sure.

=Quote=

The "Ring of Fire" is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. The Ring of Fire is composed over 75% of the world's active and dormant volcanoes.

"Japan lies at the meeting point of several of the world's major tectonic plates. This means that there is an everpresent threat from a range of natural hazards earthquakes,volcanoes and tsunami. The map shows the Philippine and Pacific Plates which are slowly moving north west towards Japan. As they move north west they slip under the Eurasan and North American Plates When one Plate slips underneath another the movement is called subduction. This whole area is very unstable and earthquakes and volcanic activity are common along both sides of plate boundaries." 

This huge ring of volcanic and seismic (earthquake) activity was noticed and described before the invention of the theory of plate tectonics theory. We now know that the Ring of Fire is located at the borders of the Pacific Plate and other major tectonic plates.

Plates are like giant rafts of the earth's surface which often slide next to, collide with, and are forced underneath other plates. Around the Ring of Fire, the Pacific Plate is colliding with and sliding underneath other plates. This process is known as subduction and the volcanically and seismically active area nearby is known as a subduction zone. There is a tremendous amount of energy created by these plates and they easily melt rock into magma, which rises to the surface as lava and forms volcanoes.

Volcanoes are temporary features on the earth's surface and there are currently about 1500 active volcanoes in the world. About ten percent of these are located in the United States.

This is a listing of major volcanic areas in the Ring of Fire:

    * In South America the Nazca plate is colliding with the South American plate. This has created the Andes and volcanoes such as Cotopaxi and Azul.

    * In Central America, the tiny Cocos plate is crashing into the North American plate and is therefore responsible for the Mexican volcanoes of Popocatepetl and Paricutun (which rose up from a cornfield in 1943 and became a instant mountains).

    * Between Northern California and British Columbia, the Pacific, Juan de Fuca, and Gorda plates have built the Cascades and the infamous Mount Saint Helens, which erupted in 1980.

    * Alaska's Aleutian Islands are growing as the Pacific plate hits the North American plate. The deep Aleutian Trench has been created at the subduction zone with a maximum depth of 25,194 feet (7679 meters).

    * From Russia's Kamchatka Peninsula to Japan, the subduction of the Pacific plate under the Eurasian plate is responsible for Japanese islands and volcanoes (such as Mt. Fuji).

    * The final section of the Ring of Fire exists where the Indo-Australian plate subducts under the Pacific plate and has created volcanoes in the New Guinea and Micronesian areas. Near New Zealand, the Pacific Plate slides under the Indo-Australian plate.

==End of quote



"The Japanese Islands belongs to four tectonic plates, that is, the Okhotsk(or North America), the Eurasia(or Amurian), the Pacific, and the Philippine Sea plates (Figure 1). The former two continental plates are colliding in Honshu, the largest island of Japan. The location of the boundary of these plates is still controvertible. Before starting of the continuous GPS observation, most researchers considered that the boundary is the Itoigawa-Shizuoka Tectonic Line(ISTL). However, the deformation revealed by the GEONET suggest that WNW-ESE contraction is localized in the zone from Niigata to Kobe(NKTZ) and that there are no large strain-rate around ISTL except its northern part. Figure 2 shows principle strain rate estimated from GPS displacements from January 1998 to January 2000. The zone where WNW-ESE strain is high extends from Niigata to north along the coast of Sea of Japan. Distribution of dilatation and maximum shear strain shown in Figures 3 and 4 clearly indicate the strain localization crossing central Japan. Therefore, NKTZ is a part of plate boundary between the Okhotsk and Eurasian plates. One important characteristic of the NKTZ is that the high-strain zone is relatively wide, say, ~100km wide, not a sharp plate boundary.""  Read more about Japan here. 

"The Indonesia earthquake was larger -- it was the third-largest in recorded history; the one off the coast of Japan Friday will likely be seventh-largest. But the biggest difference between the two is the level of preparedness. Japan, experts say, is probably the most prepared place in the world for a tsunami."

"There's a reason we use a Japanese word to describe this phenomenon," says Lori Dengler, a seismologist and tsunami expert at Humboldt State University in California. "Because Japan's been hit so many times."

A update on Japan.

They are in dire trouble. They have radioactive fuel-rods melting in three reactors.
"Fuel rods at a third nuclear plant in Japan have been fully exposed, raising the risk of a meltdown. There are now reports that there is a fire in reactor Number 4 at the Fukushima reactor. There has been another explosion at the Fukushima reactor. Japanese NHK television reports that the Number 2 reactor has exploded, releasing radiation 10,000 above normal levels. Up to half the fuel rods have been exposed and there are fears that the vessel containing the rods has cracked opening up the possibility that radioactive water is at risk of leaking outside the plant. Chief Cabinet Secretary Yukio Egano on Tuesday told reporters that "damage appears on the suppression pool" - the bottom part of the container, which contains water used to cool down the reactor and control air pressure.

Water levels have dropped precipitously inside a Japanese nuclear reactor, twice leaving the uranium fuel rods completely exposed and raising the threat of a meltdown, hours after a hydrogen explosion tore through the building housing a different reactor. Water levels were restored after the first decrease, but the rods remained partially exposed late on Monday night, increasing the risk of the spread of radiation and the potential for an eventual meltdown.

The cascading troubles in the Fukushima Dai-ichi plant compounded the immense challenges faced by the Tokyo government, already struggling to send relief to hundreds of thousands of people along the country's quake- and tsunami-ravaged coast where at least 10,000 people are believed to have died. Later, a top Japanese official said the fuel rods in all three of the most troubled nuclear reactors appeared to be melting."

"Some experts would consider that a partial meltdown. Others, though, reserve that term for times when nuclear fuel melts through a reactor's innermost chamber but not through the outer containment shell." This is qualified BS. Radioactive fuel-rods melting are radioactive fuel-rods melting."


If people just realized that most people do know how to read 'between the lines', and actually may know a little they wouldn't, hopefully, make such stupid as**s of themselves. Or maybe it doesn't matter? A lie repeated often enough will become a truth? If the melting rods gets through the confinement, and they will in time, radioactivity and heat do some pretty strange thing to all materials tested so far. There are no materials I've heard of, able to confine radioactive fuel-rods for any reasonable time over some year(s), although thick enough concrete (meters of it) will do a good job from the shorter time perspectives (like decades).

USA experimented with diluted radioactive materials embedded in metallic glass and other techniques without success, they all cracked. In Sweden we have some of the oldest stable rock in the world but we don't trust that as a longtime solution either. There are no such solutions existing in fact, the German salt mines included (they leak) The German salt-mines.

"Eventually the nuclear waste will have to be stored indefinitely because of the long time it takes for some of the waste isotopes to decay to a safe level. The consensus of most waste management specialist for final disposal is to bury the waste deep underground. In doing so we must ensure that the radioactive waste does not move from its burial site or that it does not escape into the environment. If it does it could have dire consequences for future generations such as contamination of drinking water. To ensure that the radioactive waste is contained the current consensus is to use a multi-barrier system to store the waste. The geological disposal system consists of firstly surrounding the conditioned and packaged solid waste by several human made barriers then placing this at a depth of several hundred meters in a stable geological environment. The geological formation is the most important of the isolation barriers. The barriers act in concert to initially completely isolate the radioactive particles so they can decay and then limit their release to the environment. The combination of man made and natural geological barriers is called a multibarrier system.

The solidification of nuclear waste (which is necessary for final disposal) usually consists of dispersal in a glass matrix. However, alternative techniques are being researched. One such technique consists of embedding the waste into a ceramic matrix such as Synroc.Synroc is a “synthetic rock” invented in 1978 by Professor Ted Ringwood of the Australian National University. Synroc can incorporate nearly all the elements contained in high level waste.

The barriers surrounding the solid waste vary from country to country. However most countries believe that the barriers should be made of materials that occur naturally in the earth’s crust. In Sweden, the barriers consist of

1. A copper canister with a cast iron insert. This barrier is closest to the waste and its function is to isolate the fuel from the environment.

2. The second layer consists of bentonite clay called a buffer. Its function is to protect the the canister against small movements in the rock and keep it in its place. The clay also acts as a filter in case any radioactive particles escape form the canister.

3. The geological rock. The rock also stops leaking of radioactive particles into the environment but its main function is to protect the canister and buffer from mechanical damage and to offer a stable environment for the isolation of the waste. "

So do we Swedes trust this solution :)
N o p e.

But it is the best we've found so far. I like my idea of leaving the wastes in the city's myself. Nobody will forget to check on them then :) And we will all feel 'involved', won't we? As for breeder reactors gen 4-?? Sure, I also like SF, but I have still to see any real proof for any of those working on the level we will need for taking care of our nuclear waste. Until then don't bother telling me that 'This will work!!' If we survive long enough I'm sure we will find good solutions, but until we really have them, for real, not as your beliefs or wish, until then let's put the waste in our city's. It's a gamble, but so are life, and we will at least know what we are doing, instead of slowly poisoning the planet, hiding it from sight, "out of sight, out of mind" as they say and that's the first step to a nuclear disaster. Here is a article from Scientific American. Spent Nuclear Fuel: A Trash Heap Deadly for 250,000 Years, or, a Renewable Energy Source?

When it comes to Japan. Read a more technical description here Fukushima Nuclear Accident. As for the possible leakage we will know soon enough how serious it is. Not even the largest Power companies can make the atmosphere lie, I think?

Ah, don't get me wrong. Just build the nuclear waste repositories in the middle of our major city's and I will be satisfied with our level of disaster readiness :) Or not, depending..
==

I am very sorry for all people losing their life in the Earthquake/Tsunami, and for how the nuclear situation have evolved for Japan. I truly really pray that it will cool down, and that there will be no real radioactive contamination. I'm sorry if I sounded callous here. But this situation is no Japanese situation solely. It's about all of our nuclear power plants, and their security. That Russia won't care doesn't surprise me, 'Hello Chernobyl' not to mention those areas they have that has become radioactive deserts, humans still living in them. but for those of us able to care we need to learn from it.

Can't withhold this, if true it seems more than a misunderstanding.

""Mr Edano said the figures that have been released to date measuring the level of radiation around the plant have been misquoted as micro sieverts. He said the unit attached to the figures should have been millisieverts which are 1,000 times stronger and much more damaging to human health"

And “current measurements around power plants are 400 millisieverts”

Risks from environmental levels of ionising radiation are categorised in medicine using BEIR formula, e.g.
“BEIR VI indicated that a 10 mSv single population dose is associated with a lifetime attributable risk for developing a solid cancer or leukemia in 1:1000"

1 millisievert = 1000 microsieverts.
Normal yearly dose of radiation is around 100 microsieverts.
Current measurements around power plants are 400 millisieverts == 400 000 microsieverts

That is 4000 x the normal annual dose."

I hate this. Not wanting a panic?
By giving the wrong information to the people involved?
Sh* .
=

1 Sv = 1000 mSv (millisieverts) = 1000000 μSv (microsieverts) = 100 rem = 100000 mrem (millirem); 1 mSv = 100 mrem = 0.1 rem; 1 μSv = 0.1 mrem.

"The yearly dose to individuals living close to a power plant is small - usually a fraction of a millisievert; doses to people further away are even smaller. Reprocessing nuclear fuel produces higher doses which vary greatly from plant to plant. For the most exposed members of the public, they can be as high as 0.4 millisieverts, but for most of the population they are very much smaller. World-wide, there are estimated to be four million workers exposed to artificial radiation as a result of their work, with an average yearly dose of about 1 millisievert. Another five million (mostly in civil aviation) have yearly average doses due to natural radiation of 1.7 millisieverts. "

And "The health effects of radiation may be divided into those that occur early and those that occur late. Short term: It has long been recognized that exposure to high levels of radiation can harm exposed tissues of the human body. Such radiation effects can be clinically diagnosed in the exposed individual; they are called deterministic effects because once a radiation dose above the relevant threshold has been received, they will occur and the severity depends on the dose. --

Long-term: Studies of populations exposed to radiation, especially of the survivors of the atomic bombing of Hiroshima and Nagasaki, have shown that exposure to radiation can also lead to the delayed induction of cancer and, possibly, of hereditary damage. Effects such as these cannot usually be confirmed in any particular individual exposed but can be inferred from statistical studies of large populations: they appear to occur at random in the irradiated population."

Reactor four is having a hydrogen fire. It's not getting better. I wish they hadn't told people to stay as it first happened. It had been better to evacuate them I think. The radiation is now 500 times the normal level, although I don't know what radius they mean. They are advising people to stay indoors and the worse it get the safer that will be, relatively so of course. Terrible news. Looking at the radiation levels they had earlier.

"Northerly winds carried radioactive material from the quake-damaged Fukushima No.1 nuclear power plant more than 200 kilometers south to Tokyo on Tuesday morning. Radiation levels rose in areas to the south of the plant in the hours before and after an explosion at the plant's No.2 reactor, which occurred at 6.00 AM. In Iwaki city, about 40 kilometers south of the plant, the radiation level was 470 times higher than normal as of 4:00 AM, but has since dropped." I guess they mean around that radius now too, at least? Tokyo is not far away.

This is not good.

It seems as if it is a storage pool that is to blame, also it seems to start burning to then die again. And the radiation is too high to approach it. The after quakes doesn't make it easier either, as a guess. They just had one at 6.5. And its going to be cold, with snow.

It seems as the number three reactor containment has broken too. they had smoke/vapor coming out just now, same as reactor two? Before? Missed that one. And the temperature is rising in number four.. I think this is developing into a true disaster. In Chernobyl they used the fire-mens and other help workers ignorance, or bravery if you ask their government, to limit the worst radioactivity. They died. Japan doesn't have this, possibility? if you like. How many sane people are ready to walk into a radioactive area to possibly die, and definitely come out of it very, very, sick for a very long time? Not many. Those fire-men called heroes would probably, if they had known, chosen another solution. No offense meant, but that's my view. It's a lot of white smoke now, hydrogen explosion or something else they don't know. The radiation is too high to check it. If I got it right? Over 400 000 people have been evacuated. That's amazing if correct.

I'm very sorry for all that lost their loved ones.
It's terrible.

It sounds like Chernobyl with choppers trying to cool it but it's not. And that we should be glad for. It's terrible enough as it is, Japan is so populated, and everything is so close.

"Radiation  (Chernobyl) doses on the first day were estimated to range up to 20,000 millisieverts (mSv), causing 28 deaths – six of which were firemen – by the end of July 1986...About 200,000 people ('liquidators') from all over the Soviet Union were involved in the recovery and clean-up during 1986 and 1987. They received high doses of radiation, averaging around 100 millisieverts. Some 20,000 of them received about 250 mSv and a few received 500 mSv. Later, the number of liquidators swelled to over 600,000 but most of these received only low radiation doses. The highest doses were received by about 1000 emergency workers and on-site personnel during the first day of the accident..."

but saying that 350 millisievert is 'okay' to work in? That I severely doubt. Only for a very short time if so.

The faceless 50, the unnamed operators who stayed behind. 

20 millisieverts per year = one sick per 400 persons
100 mSv per year = about 4 person per 400 sick a year.
Above 200 millisieverts per year = short-term sickness.
Above 500 millisieverts per year immune system affected.
above 1000 MsV some may die.
Above 2500 MsV a third will die
3000 MsV will cause internal bleeding

400 MsV at Fukushima reactor is bad, but not deadly.


"Anyway.. todays tools are scaled in Sievert, for volunteer fireworkers like me there are the following rules:

Max radiation allowed for saving things: 15mSv/hr
Max ... for removing danger of others peoples live: 100mSV per accident (
Max .. for saving life: 250mSv per accident

Allowed dose per year: 40mSv

Allowed dose per life: 400mSv

Basically: If you never worked in an atomic plant, stand one hour outside of Fukushima you get your max. allowed lifedose"

But it may be a race against time. "The US military said it had delivered high-pressure water pumps to Japan to help with the operation at Fukushima. High-pressure water pumps were offloaded from USNS Safeguard in Yokosuka last night and delivered to Yokota Air Force Base for further transfer to the government of Japan for employment at the Fukushima power plant," the US Pacific Fleet said in a statement."

satellite images of Japan showing damage after an Earthquake and Tsunami. 

"The International Atomic Energy Agency has rated the radiation release there 4 on a scale of 7. Three Mile Island was rated as 5/7 and Chernobyl was rated 7/7. Each additional point on this scale represents a factor of 10, so the current situation at Fukushima is 1/10th as serious as that at Three Mile Island, and 1/1000th as serious as Chernobyl, according to the agency.

Q: What happened at Three Mile Island? A: On March 28, 1979, unit 2 suffered a partial meltdown after water meant for cooling the uranium fuel was released from the containment chamber due to an equipment malfunction. There was no explosion and radioactive materials weren’t released into the environment because the chamber didn’t rupture. "

And it this that can't be allowed to happen. That the uranium fuel is released inside the containment chamber and ruptures. Then the melted rods will be able to eat themselves through the concrete floor and also create new explosions. As if that wasn't enough  "international Atomic Energy Agency (IAEA) head Yukiya Amano confirmed that reactors No. 1, No. 2 and No. 3. had partially melted down. He added that Japanese authorities also had reported concerns about the spent nuclear fuel pools of reactors No. 3 and No. 4.

The deep tanks contain used fuel rods which are extremely radioactive and normally kept immersed in cooling water. Unlike the fuel rods that are used in the reactor vessel, the spent rods are not surrounded by a steel-and-concrete containment vessel. If water in the pools evaporated, the spent rods would be exposed to the air and radioactive material would be released into the atmosphere." "US Energy Secretary Steven Chu told Congress Wednesday that Japan's ongoing nuclear crisis appears "more serious" than the 1979 Three Mile Island partial reactor meltdown...Chu said DOE has sent 39 people and 17,000 pounds of equipment -- including radiation detectors and aerial measuring systems -- to Japan to help the country deal with the crisis.

"We are going to be looking very, very closely at the events happening in Japan and take those lessons," Chu said. "We will be looking very carefully and gathering whatever lessons can be learned and apply them to all the nuclear facilities we have in the US.""

"Currently the reactors are releasing small amounts of xenon-137 and iodine-131, which have a half life of 3.8-minutes and eight days respectively. But experts are more concerned by the release of cesium-137, which has a 30-year half-life. Professor Byrne says there is still a chance the Japanese reactors could go into meltdown.

"It's not impossible because they have problems with the coolant," he said. "The Three Mile Island accident which is the previous one similar to this certainly did have a core meltdown, so it could happen in one or maybe even two of these [reactors]. "The anxiety here is that it ruptures explosively and projects stuff into the atmosphere ... but even then it would not be of the magnitude of the Chernobyl reactor." Professor Byrne says it is not possible to speculate on how bad the health effects would be because it would depend on the amount of radiation released and where the prevailing winds took the particles. But he says as long as efforts to cool the reactors continue, the likelihood of a complete meltdown will decrease."

And last but not least; How to Stop a Nuclear Meltdown.   

And there seems to be 13 400 dead and counting, as for now. And with snow and the cold continuing around zero the evacuees situation becomes constantly worse, in their provisional shelters without food, medicine, heat and water. The government seem to try to move some to new shelters, further away, a worrying sign. And with Tokyo soon without food and water, just 200 kilometers away? In a worst case scenario it will be a nightmare come true. And if you believe, send a prayer for those faceless fifty, those that stayed in a environment where every hour becomes a lifetime of radiation, I think they can need all help they can get, divine or not. They are the true heroes here. Just found new information about them. They are 200 working in shifts of fifty. We should all be proud over people like that, they represent the best in us.

Two are missing after fire explosion today.
But the rest goes on, wish them well..

They're dumping water now from choppers 7.5 tons per load. And they will use water cannons from the ground. Those doing it is worth a salute. And those making money on Japan stinks, buying and selling yen. USA have advised its citizens to evacuate a eighty kilometers radius around the Fukushima reactor. It is an American reactor so they may have a lot more statistics on them? Don't know how serious one need to take it? It depends on what they have seen in those tests the Japanese have delivered to them. but to evacuate such a large area, in Japan? I think they are having dire trouble with the shelters they already have.

Swedish waterfall will cry.

The company directors should be put in jail. They went and bought Germany's power plants, so now we Swedes are responsible for the German power production, and the Germans ? Well, They're closing down on nuclear energy, so suddenly Vattenfall is advocating .. Coal(!) ah, as a 'renewable' energy source? in Germany, well more or less :) So f*ng sad, and it wasn't even their private property. It was the Swedish peoples, but with idiots acting as if it was, with the right wing applauding as they want to sell it all out, and well, the 'taxes' sinks when you sell of our common heritage, don't they :) momentarily at least. And if the right wing sell Swedish common property off cheap enough, and they do, oh yes they really do :) the rich will buy... Our new government have been selling out our property for over ten years now, with our new 'middle class' applauding it. Soon everything we worked up will be gone into private hands with only what they can't sell staying as the 'peoples' responsibility. Meaning that the rich gets richer, and those without tax deductions will stand for the rest.. Stinks..

And hey,  they're selling Sweden off cheap too :)
A tip, buy buy buy.

Well, what can one say? Suddenly the Swedish people have become the 'guarantee' for German power production, and as a guess if the Germans want to dismantle their nuclear power plants they will try to off load it at Vattenfall. Those directors creating this clusterfu** should should be interned in a asylum, for ever, never letting them out again. Instead they get bonuses :)

Power suits in action, world wide ::))
A f*ng joke. Just like the international banking system.

Take a look To Shut Down Isar 1 Reactor As Part Of Govt Nuclear Moratorium.

Wouldn't surprise me if Vattenfall will go into bankruptcy. It's either that or us Swedish people taking care of two countries nuclear dismantling, alternatively renewal and upgrading. Get a real Government back Sweden, listening to reason and common sense instead.
==

Don't get me wrong. Sweden lost their 'sight' a long time before that, our 'SocialDemocrats' becoming the forerunners of privatization. I don't see us having any real 'political parties' having foresight any more. And no, I am not advocting for a 'leftist' government. Or right wing.. Just advocating for people trying do what is good for us all, instead of what is good for their own pockets, or idiotic 'politic theories'. There are no such thing as 'political theories' the red Khmer's, peoples revolution in China, communist revolution and subsequent Putin regime all can tell you that. A right wing government is in one way truthful, ain't they :) At least they tell you that they want to privatize, only lying when telling you how good it will be for you. Even though privatization will be good for some, it won't be true for a whole population, assuming that the government before wasn't totally corrupted that is.

I always found the 'middle way' being the best, with power, water and medical services best being in the hands of the Country, not commercial interests. They are not to be 'supply and demand'. John Locke's general theory of value and price was the 'supply and demand' theory, well fitted to the time he lived in, but also leading to the robber barons. To day the world is small, very small. But we still have greed as our primary goal it seems, whatever 'political theory' we hide behind. That has to stop.

it seems like they succeeded to get some water to the number 3 reactor  (the most dangerous one) by ground (fire brigade) but they still have a lot of problems with getting out help to the evacuees. and the radiation have sunk slightly, but it's still a provisional solution. They are trying to start the electrical systems and the reactor pumps too, for cooling. But that one has to be a 'long shot'.

Okay two links I've found to the construction and safety aspects of those reactors in Japan.
Boiling Water Reactor Power Plant (Japan) That one I just point you too as I found it a pay-site, alternatively registering. But

"Bascially the fuel is the greatest source of radioactive species at the NPP, especially once it has operated in the core. The fission products and transmuted fuel nuclei are supposed to be retained by the fuel - firstly in the ceramic pellets - then by the cladding surrounding the pellets. Problems arise when the cladding is breached (fuel failure). Fuel particles containing isotopes of U, Np, Pu, Am and Cm, and fission products get into the coolant, or in a BWR, may find their way to the turbine, and ex-core cooling systems. Spent fuel is quite radioactive.

Fission gases (Xe, Kr) and volatiles like I, Cs are also problematic because they can be transported out of the core. In BWRs with degraded failed fuel, Xe, Kr, I and Cs are problems for folks working on turbines and BOP. Sometimes workers must wait on sight to degass, release the Xe, Kr they have inhaled.

Next corrosion products (know as crud) which deposit on the fuel during operation will become activitated, and structural materials in the core also become activated by neutron absorption. These corrosion products may find their way out of the core. This is a problem when a reactor shutsdown for refueling and the top is removed. Prior to removal, a cleanup system runs in order to wash out the loose crud, which is collected on a filter. More tenacious crud will be carried on the fuel to the spent fuel pool.

In BWRs using Hydrogen water chemistry, the can be carry over of N-16 (produced by (n,p) reaction with O-16) to the turbine. Some BWR plants have had a problem of gamma shine on workers or control room personnel because the steam lines passed near the control room. There are other radiation sources, e.g., primary and secondary neutron sources, as well as calibration sources."

And here is the other BWR_Safety_Design.pdf this one is a direct download. I had some trouble finding them, the original site in Japan didn't allow me to download them at all and I seemed unable to connect to it?

And lastly. Sample Core Damage Frequency Insights for Boiling Water Reactor. and some references on radiation protection and monitoring from Brookhaven


Those are all

So how serious is it?

Well the earthquake (8.9) alone was .. thirty times .. worse than the famous 1906 (at magnitude 8) San Fransisco earthquake. The Tsunami itself came with a almost 8 (26 feet) meter high wave, new approximations suggest 13 meter high (43 feet) at the highest. that they became so high has to do with the length of the Eartquake, Five Minutes long... That is unheard of I think.. It's very long. "As of 06:30 this morning, 18 March, the Tokyo Fire Department was continuing to spray water into reactor 3, the Nuclear and Industrial Safety Agency reported. Meanwhile engineers have successfully begun laying an external grid power line cable between the transmission line and unit 2. They plan to reconnect power to unit 2 once the spraying of water on the unit 3 reactor building is completed." 50 tons of water have been flushed at reactor 3 today. And they are worried for the safety of reactor 2 as I understands it, just because it seems 'whole' still. They don't really now what's going on in there. Radiation dose rates are fluctuating based on some of the relief operations, such as adding cooling water to the used fuel pools. Recent readings at the plant boundary are about 2 millirem per hour. Radiation dose rates at reactor 3 range between 2,500 and 5,000 millirem per hour. The cooling seems to work so far.

So yes, I'm sort of scared. I'm scared for the safety of those eighteen millions (+) living 220 km from the site. Nobody knows how many there are living there in reality it seems, but, if there is a panic and they all start to leave, going outside?

Not good. Especially as it probably will be if the radiation gets dangerously high.

So far we only heard about reactor 1-4 right?
But, how many reactors are we talking about at Fukushima plant?
The real number is six.

" At the 40-year-old Fukushima Daiichi unit 1, where an explosion Saturday destroyed a building housing the reactor, the spent fuel pool, in accordance with General Electric’s design, is placed above the reactor. Tokyo Electric said it was trying to figure out how to maintain water levels in the pools, indicating that the normal safety systems there had failed, too. Failure to keep adequate water levels in a pool would lead to a catastrophic fire, said nuclear experts, some of whom think that unit 1’s pool may now be outside.

“That would be like Chernobyl on steroids,” said Arnie Gundersen, a nuclear engineer at Fairewinds Associates and a member of the public oversight panel for the Vermont Yankee nuclear plant, which is identical to the Fukushima Daiichi unit 1. People familiar with the plant said there are seven spent fuel pools at Fukushima Daiichi, many of them densely packed.

Gundersen said the unit 1 pool could have as much as 20 years of spent fuel rods, which are still radioactive. The Fukushima Daiichi plant has seven pools for spent fuel rods.  Six of these are (or were) located at the top of six reactor buildings. 

One “common pool” is at ground level in a separate building.  Each “reactor top” pool holds 3450 fuel rod assemblies.  The common pool holds 6291 fuel rod assemblies.  [The common pool has windows on one wall which were almost certainly destroyed by the tsunami.]  Each assembly holds sixty-three fuel rods.  This means the Fukushima Daiichi plant may contain over 600,000 spent fuel rods."

Add to that "Pentagon officials reported Sunday that helicopters flying 60 miles from the Fukushima Daiichi nuclear plant picked up small amounts of radioactive particulates — still being analyzed, but presumed to include cesium-137 and iodine-121 — suggesting widening environmental contamination. The detection of the highly radioactive elements heralds the beginning of an ecological and human tragedy. The two radioactive isotopes can mean only one thing: One or more of the reactor cores is badly damaged and at least partially melted down."

And HAZARDS OF BOILING WATER REACTORS IN THE UNITED STATES.

And "The Fukushima Units #1 through #5 at Daiichi are older GE designed BWR-3 and BWR-4 Mk.I, boiling water reactors that were all built in the 1970's.  I used to design fuel for these types of reactors when I worked at GE some years ago.  In general, I would say that BWRs are actually inherently safer than PWRs.  When I was at GE they used to say that BWR stood for "BEST Water Reactor."  This older design, however, is not the best design for accident scenarios.  It has a torus or "doughnut" for the suppression pool and it is limited in its capacity.  Also, these containment structures are smaller than later designs, and generally considered not as robust."

And considering what happened this seems to fit in. "For station blackout accidents, containment systems will not be functional and the drywell floor will often be dry, leaving the plant susceptible to drywell shell melt-through. In addition, the reactor vessel will normally be at elevated pressure, which increases the containment loads at vessel breach. This means that station blackout accidents pose a severe challenge to Mark I and Mark II containments, and therefore, these accidents are often important contributors to the frequency of containment failure."

So, how can we find out what's really going on there? We can't go into them to look, not without playing Russian roulette. " Washington possesses some unique assets.  One asset – the secretive National Reconassiance Office – runs the spy satellites remote sensing devices that enable US national security to spy on planet Earth.   The NRO’s slightly less secretive cousin over at the the Pentagon is the Defense Intelligence Agency.  The DIA, in turn, controls MASINT “measures and signatures technologies”.

What is MASINT?  FDL’s recent guest Tim Shorrock answered that question a few years ago for CorpWatch: MASINT is a highly classified form of intelligence that uses infrared sensors and other technologies to “sniff” the atmosphere for certain chemicals and electro-magnetic activity and “see” beneath bridges and forest canopies. Using its tools, analysts can detect signs that a nuclear power plant is producing plutonium, determine from truck exhaust what types of vehicles are in a convoy, and detect people and weapons hidden from the view of satellites or photoreconnaissance aircraft."

So, now I wonder, what do they see?

Seems the pressure is raising in reactor three. They are going to release some water from the containment vessel to equal out the pressure. They can't use the (internal) suppression pool for this, so there will be a raised radioactivity outside it. but if they don't release the pressure the reactor may burst.

Serious stuff, making it even more difficult to handle.

There is still a lot of 'after shakes' going on. Must be terrifying not knowing how strong they will be.

"Maximum intensity 4 earthquake off the coast of Ibaraki Prefecture 2011/3/21 23:21:26 M5.8 occurred depth 30km  Maximum intensity 3 earthquake in western Kanagawa Prefectur  2011/3/21 23:27:26 M4.0 occurred 10km depth."

And reactor 2 is still a worry for the Japanese, there came whitish smoke from that one, and reactor 3, earlier. And with it the radiation started to fluctuate between 2000-400 microsieverts, some five km away if I got this right? And reactor three had thick black smoke coming from the used reactor pool. It makes me wonder if they shouldn't start to plan for the same as at Chernobyl? Where they, from the second to tenth day, dumped around 5000 tonnes of boron, dolomite, sand, clay and lead on the burning core using helicopters, trying to extinguish the blaze and limit the release of radioactive particles. I'm not saying that they need to do it. Just that they should prepare. It's better to be prepared before than after, I think, and if needed that one will take some serious logistics to plan for
