That's why they go crazy with IP laws. It's a great way to censor information.There's an interesting Mises Institute lecture revolving around IP laws eventually being the end of western civilization as a whole, and it makes a good case for it. That's part of why we're stagnating culturally so extremely. The best composers built on the work of others as a rule. . . Now, they'd be sued for millions of dollars and/or thrown in jail.

No doubt. Five years ago, I could search the web from a geograpicically-neutral position, but today, being Canadian and having a Canadian-based IP address, I spend half of my effort trying to defilter the Canadian filter. They're getting us not just by blocking content, but by shaping and targeting content.

2015

RFID-like technology in every single consumer and industrial product. Now you can track a product in real-time as it leaves the warehouse, travels, get's shelved, then bought (that YOU bought it when, where and for what price and by what method - log PIN# or clues thereof, and analyze the rationale for he or she going to that store BEFORE having bacon and eggs at John's Diner one hour earlier, where he strangely paid with cash -- or so we deduce because there is no payment data.

Now imagine the streets and the airwaves saturated with readers to the point that every single thing you do in life will be cataloged, forever, with the intent of predicting and controlling you.

That sucks!

I still can see it? Important Vid Fukushima I Nuclear Power Plant http://www.youtube.com/watch?v=7vhuVUt5l_k

Anyways, some important screenerz from that Vid cause there you can see that the top of Unit-3 has been completely blown off including the fuel and spent fuel cooling pond.

A) The 6-inch thick metal reactor containment vessel has blown up inside the concrete primary containment wall which is peech shaped with at the top the weakest point - the fuel transfer gate.

Or B) The fuel burned it's way trough the containment vessel and exploded underneath in which case the 6-inch thick metal reactor containment vessel would be blown out like a cannonball.

Either way the the concrete primary containment wall worked as a canon when it blew up sky high directing the explosion force straight up which can be clearly seen

PRESSURE RISING IN THE MOST THREATENING REACTOR UNIT-3

PRESSURE RISING IN THE MOST THREATENING REACTOR UNIT-3
21 March 2011
, (Reuters - The Jerusalem Post)
http://www.jpost.com/VideoArticles/Video/Article.aspx?id=213109

Excerpt:

Some workers were later evacuated from one of the most badly damaged reactors when gray smoke rose from the site.

There was no immediate explanation for the smoke, but authorities had said earlier that pressure was building up at the No. 3 reactor. The amount of smoke later receded.

Japan's nuclear safety agency said pressure was rising in the most threatening reactor, No. 3, which contains highly toxic plutonium,

and this may have to be released by "venting" steam, a step taken last week that discharged low levels of radiation into the atmosphere.

If the cooling pumps cannot restart, drastic measures may be needed like burying the plant in sand and concrete.

The health ministry has urged some residents near the plant to stop drinking tap water after high levels of radioactive iodine were detected.

The government has prohibited the sale of raw milk from Fukushima prefecture and spinach from a nearby area.


Japanese nuclear plant withdraws workers

http://www.cp24.com/servlet/an/local/CTVNews/20110321/110321_japan_earthquake/20110321/?hub=CP24Home

Excerpt:

Smoke rising from the spent fuel storage pool of the plant's Unit 3 prompted the evacuation, Tokyo Electric Power Co. spokesman Hiroshi Aizawa said.

The problem-plagued Unit 3 also alarmed plant officials over the weekend with a sudden surge of pressure in its reactor core.

----

But the buildup in pressure inside the vessel holding Unit 3's reactor presented some danger, forcing officials to consider venting.

The tactic produced explosions of radioactive gas during the early days of the crisis.

"Even if certain things go smoothly, there would be twists and turns," Chief Cabinet Secretary Yukio Edano told reporters.

"At the moment, we are not so optimistic that there will be a breakthrough."

Growing concerns about radiation add to the overwhelming chain of disasters Japan has struggled with since the 9.0-magnitude quake.

What Caused The Smoke At Fukushima Power Plant? Can you say FISSIONING?
« Reply #15 on: March 21, 2011, 10:06:40 AM »
What caused the smoke? Can you say FISSIONING?

Definition of FISSION

1: a splitting or breaking up into parts

2: reproduction by spontaneous division of the body into two or more parts each of which grows into a complete organism

3: the splitting of an atomic nucleus resulting in the release of large amounts of energy


ROUND 70% OF THE NUCLEAR FUEL RODS IN UNIT-1 reactor have been damaged.

Minoru Ohgoda said: “We don’t know the nature of the damage, and it could be either melting, or there might be some holes in them.”

33% OF THE FUEL RODS AT UNIT-2 WERE ALSO DAMAGED.

FROM March 16, 2011: Staff Evacuated From Japanese Nuclear Plant http://news.sky.com/skynews/Home/World-News/VIDEO-Nuclear-Incident-Increases-Radiation-Has-Leaked-From-Fukushima-Plant/Article/201103315952984

UNIT-3 FUEL RODS ???



- "... but I still cannot bring myself to describe material that is still 95% potential fuel as 'spent'. http://atomicinsights.blogspot.com/2011/03/stop-worrying-about-spent-fuel-pool.html

- Radioactive FISSION gases and some of the fuel’s radioactive material in the form of aerosols into the building that houses the spent fuel pool and possibly into the environment. http://my.firedoglake.com/kirkmurphy/2011/03/15/why-fukushimas-spent-fuel-rods-will-continue-to-catch-fire/

- FISSION GAS release in MOX fuel assemblies may limit the maximum burn-up time of MOX fuel. http://en.wikipedia.org/wiki/MOX_fuel

Danger of Losing Control of the Reactor Is Greater with MOX

Conventional LWRs are designed to decrease the reactivity when the temperature rises.

- But when using Pu-239 as fuel, heating of the core from an increase in reaction rate tends to increase the reaction rate still further.

For UNIT-3: This is called the positive temperature coefficient of reactivity, meaning there is a danger of losing control of the reactor by accelerated chain reaction of FISSIONING.

FROM: TECHNICAL ASPECTS OF MOX FUEL IN LIGHT WATER REACTORS/THE REACTOR OPTION http://www.nirs.org/reactorwatch/mox/puupdat4.txt



Fukushima Daiichi nuclear power plant at TEPCO, iodine-131 has been detected six times the standard concentration. Cesium is also found.

Typical substances formed by the FISSION. Both were certain that the damaged nuclear fuel in nuclear reactors and spent fuel pool.

The Tokyo Electric Power, 19 airborne material collected from about 200 meters northwest of No. 1 were examined for the first time after the accident.

As a result, the concentration of iodine 131 was 5.9 per 1cc Miribekureru.

Continue to smoke one year, exposure to 300 mSv (nuked), but concentrations.

Workers, are working with a mask to enter the body.

This also found that iodine 132 Miribekureru 2.2, 0.04 Miribekureru 133, cesium 134 and 137 are both Miribekureru was 0.02.

There does not seem to be (as yet) any runaway fission processes going on among the spent or unused fuel rods but one cannot rule out the very high likelihood that the warped, badly melted and destroyed reactor cores may not develop unfavorable depositions and/or geometries in either contained or uncontained leaky pressure vessels that even borated water flush SCRAMMING COULD NOT STOP.

In fact just the runaway decay heat alone in these three reactor's only "one week-old" (since shutdown) reactor cores would still be RADIATING nearly 1.8-5.2 Megawatts (Uranium or Plutonium MOX) of heat each and with no cooling water (and salted cooling water pollution now) they are now just lumps of poison thermonuclear crud in there, that cannot even be cooled without making hydrogen gas, 131Iodone (and dozens of other radioactive fission byproduct poison-pollutants)  and massive steam pressures that would blow the vessels - if they are even intact..

Those three reactors are now totally complete and absolute useless poisonous and deadly GARBAGE THAT MUST BE BURIED FOREVER, there is no repairing, fixing or doing anything else with them. Just dicking around vainly screwing around with them by these 3 TEPCO STOOGES is pure insanity.

Permanent eternal entombment must begin two days ago.

With any luck these three fission cores will remain stable despite melting because of their control rod content alone, perhaps boron-water injection (liquid SCRAM poisoning) could further help stabilize them for burial - but they must all three be buried, there is no other option.

Rescuing, salvaging or burying the fuel rods while the entombment progresses is a secondary matter, that offers dubious risk/rewards. Without a moderator the fuels should remain relatively harmless, though there may be time to remove it to storage elsewhere.

The real issue is the unpredictable and unknowable horrific fully or partially armed condition and state of the horrifically damaged fuelled/cores inside the ruined and destroyed completely worthless and unsalvageable reactors. There may only be a few more days or weeks before they blow.

It's most important to SCRAM THEM NOW while they are being entombed

You seem to know an awfully lot about the subject so maybe you like to speculate with me.

What happened to spent fuel pool from Unit-3 and where is it now?

The extreme explosion from Unit-3 had 3 bangs caused by exploding water seeking to depressure according to Dr. John Waterman Download MP3: http://www.americanfreedomradio.com/archive/Project-Camelot-32k-031611.mp3

Finaly it depressurized by blowing of the top floor of Unit-3 including the (15) Spent Fuel Pool and storage racks, the (2) Equipment Storage Pool (like Steam Dryers and Seperators) and (10) two Condensers. (See Schematic Under)


So what happened according to you?

A The 6-inch thick metal Primary Reactor Containment Vessel has blown up inside the peech shaped (30) Drywell Concrete Containment Vessel or the Fuel burned it's way trough the Containment Vessel and exploded underneath and around the 6-Inch thick Metal Primary Reactor Containment Vessel but in the Drywell Concrete Containment Vessel with at the top the weakest point - the Drywell Head and Fuel Transfer Gate.

Either way the the Drywell concrete Containment Vessel worked as a canon when it blew up sky high directing the explosion force straight up and taking the concrete top floor including the Fuel Pools and the concrete Drywell Head with it into the air.

What happened with the The 6-inch thick metal Primary Reactor Containment Vessel? I donnow?

And what's this?

RADIATION IS NOW BEING MEASURED AS FAR AS LAKE SUPERIOR

ColonelCooper says: "A line of radiation monitors that spans from ND to KS are picking up the elevated radiation levels that were on the coast a day or two ago ???

https://cdxnode64.epa.gov/radnet-public/showMap.do

My own Geiger, is/was reading at nearly double (50CPM) what has been a relatively stable background level of 15-20. (This is still inside the “normal” range however) The monitor east of me is/was reading 90CPM.

Levels in SD are over 200 right now. This is more than 3 times what RadiationNetwork considers normal, considering the elevation there.

These are far from dangerous at this point; I’m not posting this from a lead lined bunker, and I’m not trying to freak anyone out.

I just find it ironic that the RADIATION THAT “WASN’T EVEN GOING TO GET HERE”, IS NOW BEING MEASURED AS FAR AS LAKE SUPERIOR."

Fukushima Daiichi nuclear power plant, nuclear fuel damage – detected six times the standard iodine (Google trans from Japanese) http://tinyurl.com/6zzems2

FACT SHEET ON FUKUSHIMA NUCLEAR POWER PLANT
http://nirs.org/reactorwatch/accidents/Fukushimafactsheet.pdf
 
UPDATE 12:30 pm, Monday, March 14, 2011. According to our colleagues in Japan, Tokyo Electric Power states that Fukushima Daiichi-2 “has again lost its coolant (sea water was pumped in but is dropping). They cannot ease the reactor pressure because the relief valve is stuck closed. Air dose rate on site (outside the reactor building) was 3,130 at around 9:30pm.” We believe the 3,130 figure means 3,130 MicroSievert/hour, which would be highest reading yet recorded—about 310 millirems/hour. For comparison, the U.S. EPA allowable dose to a member of the public from a single reactor is 25 millirems/year, the U.S. NRC’s allowable dose is 100 millirems/year from all nuclear sources.

16 March 2011
, by Rod Adams (Atomic Insights)
http://atomicinsights.blogspot.com/2011/03/fepc-information-sheet-for-fukushima.html
 
Radiation levels at the site are reported to be 1,015 micro/Sieverts per hour. This is roughly equivalent to 100 millirems/hour. The allowable annual dose for members of the public from nuclear facilities in the U.S. is 100 millirems/year. The allowable annual dose for nuclear workers is 5,000 millirems/year. The average annual background dose from all radiation sources in the U.S. is about 360 millirems/year.

Daiichi plant historically problem-prone
21 March 2011
, (UPI)
http://www.upi.com/Top_News/World-News/2011/03/21/Daiichi-plant-historically-problem-prone/UPI-87341300751832/

Excerpt:

Documents show the Fukushima Daiichi power plant was already one of Japan's most trouble-prone nuclear facilities even before the current crisis, analysts say.

A Wall Street Journal analysis of safety and maintenance practices released Monday alleges how the plant's age, structure and work procedures threatened to spin the situation at the nuclear reactor out of control.

The Japan Nuclear Energy Safety Organization, a mostly government-funded group monitoring safety and conducting inspections, reported Daiichi had the highest accident rate of any big Japanese nuclear plant.

The data shows Daiichi's workers were exposed to more radiation than their peers at most other plants, the Journal reported.

Since 2005, the Daiichi plant has had 15 accidents, the most of any Japanese plant containing more than three reactors with maintenance problems as the leading cause.

----

All of Daiichi's reactors came online in the 1970s.

"(Since) Fukushima Daiichi has older reactors, it requires more frequent repairs and checks than new nuclear plants." Because the plant is of an old design, "radiation tends to be higher," said Teruaki Kobayashi, head of TEPCO's nuclear-plant-management section.

Honestly you can't make this bulls hit up! LOL

Radiation should always 'tend' to be null, otherwise the thing should be scrapped.

As with all other GE appliances the moment it fails it must be tossed out. If you change one part the rest get jealous.

Following Radioactive Rain, Radiation In Tokyo Jumps 10 Fold, Hitachinaka Iodine 131 Surges To 85,000 Becquerels
22 March 2011
, by Tyler Durden (Zero Hedge)
http://www.zerohedge.com/article/following-radioactive-rain-radiation-tokyo-jumps-10-fold-hitachinaka-iodine-131-surges-85000

Excerpt:

To wit, from the Asahi: "Iodine 131 detected in Tokyo hit 12,000 becquerels, compared with the previous day: a tenfold increase in both radioactive Iodine and Cesium."

As for Hitachinaka City, which according to SPEEDI has seen a surge in radiation over the past 24 hours, things are far worse: "Hitachinaka City, Ibaraki Prefecture, saw the highest radioactive values recorded, with 12,000 becquerels of cesium, iodine and 85,000 becquerels."


Per Asahi (google translated): http://tinyurl.com/63txq2a

Ministry of Education, under the influence of Fukushima Daiichi nuclear power plant accident, announced the results of such measurements with radioactive dust fell from the sky.

Tended to increase mainly in metropolitan areas. 5300 becquerels per square meter of cesium in Shinjuku, Tokyo 137,3 detection of iodine 131 becquerels 12,000, compared with the previous day, rose about 10 times the concentration of both. The values ??that affect health, but prolonged monitoring is needed.

Measurement of radioactive fallout, we put the nation at 9:00 am on October 22 from 9 am to 21 the ministry, were analyzed.

The value of Tokyo, yesterday's Cs 560 Becquerel, Becquerel 2900 soared from iodine. Announced value of the cesium 22, 8 / 1 40,000 becquerels of radiation controlled area reference value, iodine value, amount to five quarters.

The values ??of cesium in other municipalities, the 1600 Becquerel Saitama City (790 becquerels day), Kofu, 400 becquerels (the non-detection), Utsunomiya 440 becquerels (250 becquerels same), and rose across the board.

The day before, in Hitachinaka City, Ibaraki Prefecture, the highest values ??were recorded, although down slightly, 12,000 becquerels of cesium, iodine and 85,000 becquerels[/u], still higher values ??are recorded. Fukushima and Miyagi can not be measured.

In the east, where it snowed a lot of rain and dust and floating in the atmosphere, believed to have dropped radioactive material. The short half-life of iodine, 8 days half-life of cesium in 30 years, continue serving after getting off the ground a long period of radiation. Soil and water, because it could lead to radioactive contamination of agricultural products, should continue to monitor future.

Fukushima Nuclear Reactor Problem Explained http://www.youtube.com/watch?v=BdbitRlbLDc

This video is an elaborate lie. When radioactive cooling water fails the water turns into radioactive steam pressure and explosive hydrogen which lowers the radioactive water levels. Without venting the radioactive steam and hydrogen to the atmosphere, sea water (Nor any liquid) cannot be added (the big so-called "injecting water" lie). This was when they likely first exploded the containment vessels or cooling plumbing. ( simply due to overpressure in reactor #2, and also likely also in 1 and/or 3)

Then, to cool the core, the now-radioactive heated sea water must also be steadily drained out and replaced with fresh, cooler sea water continuously, just to cool them a bit down through the 'feet' of the things. (an awesomely inefficient joke in this totally defective Navy Surplus design since all heat always rises)

Unfortunately. the moment the sea water reaches (douses) the height of any overheated parts, the pressure and hydrogen pressures again very, very rapidly rise and must again also be vented-out to the atmosphere. This tediously slow vicious circle again and again would be a very, very long process that they surely never accomplished due to radiation levels going crazy and them being evacuated again and again (and water disappearing, steam and hydrogen building up huge pressures and the heat ever-increasing all-along steadily.

Meanwhile the fuel rod pools above also desperately failed and not cooling many megawatts of hot fuel rods were also overheating evaporating and producing explosive hydrogen, it seems the only storage pool they were successfully moderately cooling by polluting the ocean was in #2 where the roof explosion was somehow avoided, rumor says they punched a hole in the roof to vent the light hydrogen before it exploded - but this also let out Iodine etc.

It took too long to even begin doing this during which time most of the cores, fuel rods and control rods turned into a massive lump of radioactive crud that cannot even be cooled and are probably partly critical once again here and there due to unfavorable new melted geometries!

The #2 and #3 reactors now appear to have blown containment vessels and are likely partly critical, perhaps they can save the #1 reactor from the same fate.

nevertheless the entire installation is doomed.

Fukushima Update: Reactor 1 Core Now At 380 Degrees Celsius, 80 More Than Normal Running Temperature
22 March 2011
, by Tyler Durden (Zero Hedge)
http://www.zerohedge.com/article/fukushima-update-reactor-1-core-now-380-celsius-80-more-normal-running-temporature

Excerpt:

The news this time comes straight from TEPCO which finally admits that the temperature of Reactor 1 is 380-390 Celsius (715-735 Fahrenheit), which apparently is a "worry" as the reactor was meant to run at a temperature of 302 C (575 F). That is when the reactor is fully operational, not when it is supposed to be in a cold shut down mode.

Reuters: http://www.reuters.com/article/2011/03/22/us-japan-quake-idUSTRE72A0SS20110322?WT.tsrc=Social%20Media&WT.z_smid=twtr-reuters_%20com&WT.z_smid_dest=Twitter

As was reported only on Zero Hedge so far, the termal imagery from Fukushima indicates that if reactor one is a "worry", then

reactor 3 should be a "nightmare", as according to some it is now "operating" north of 500 degrees celsius,

and possibly as high as a 1,000.

That's three times what it is designed to withstand.

The Case For Nuclear Fukushima Daiixhi Unit-3 Top Blown Completely Off Slideshow

Top of Unit-3 has been completely blown off including the fuel and spent fuel cooling pond.

So What happened?

A) The 6-inch thick metal reactor containment vessel has blown up inside the concrete primary containment wall which is peech shaped with at the top the weakest point - the fuel transfer gate.

Or B) The fuel burned it's way trough the containment vessel and exploded underneath in which case the 6-inch thick metal reactor containment vessel would be blown out like a cannonball.

Either way the the concrete primary containment wall worked as a canon when it blew up sky high directing the explosion force straight up which can be clearly seen

60% Chernobyl Level Reached!!! Contamination Will Remain For "Decades & Decades"

UPDATE, Noon, Wednesday, March 23, 2011: http://nirs.org/reactorwatch/accidents/Fukushimafactsheet.pdf

The Austrian Central Institute for Meteorology and Geodynamics (ZAMG), which is advising the International Atomic Energy Agency, reports that releases of radioactive Cesium (hazardous life: 300-600 years) from Fukushima

now are 20-60% those of Chernobyl; releases of Iodine-131 are at 20% Chernobyl releases.


UPDATE, 11:00 am, Wednesday, March 23, 2011.

Radioactive Iodine-131 has been found in Tokyo’s water supply at twice the allowable level for infants.

The government is telling people not to let infants drink tap water or use it in formula.

Since Tokyo is some 150 miles away, it is likely elevated levels of radiation are also being found in other cities’ water, although this has not been confirmed.

The U.S. Food and Drug Administration has banned import of milk and vegetables from Japan to the United States.


Today’s excel spreadsheet on radiation levels in surrounding communities shows a continued slight decline in these levels.

However, we point out that all of the levels are far above background and above levels allowable for long-term human habitation.

We also point out that all of the monitoring locations are outside the current evacuation zone, in most cases many miles outside.

Agence France-Presse is reporting that France’s Nuclear Safety Authority says that local contamination in the area is a problem that will remain for “decades and decades.”

Radioactive Iodine In Fukushima Seawater Highest Ever, Reactors 5 And 6 Now Leaking Too
24 March 2011
, by Tyler Durden (Zero Hedge)
http://www.zerohedge.com/article/radioactive-iodine-fukushima-seawater-highest-ever-reactors-5-and-6-now-leaking-too

Excerpt:

The radioactive fallout from Fukushima continues to worsen as Iodine 131 levels in the seawater hits the highest since the start of the crisis.

"According to Tokyo Electric Power Co., radioactive iodine-131 146.9 times higher than the legal concentration limit was detected Wednesday morning in a seawater sample taken around 330 meters south of the plant, near the drain outlets of its troubled four reactors.

The level briefly fell to 29.8 times the limit on Tuesday morning from 126.7 times on Monday, but rose to its highest so far in the survey begun this week apparently due to rain and water sprayed at spent fuel pools from outside that caused radioactive materials to seep into the sea, it said."

What's far worse, reactors 5 and 6 which have been supposed to be ok, are also leaking:

"The firm also said it found both iodine-131 and cesium-137 in a sample taken from near the drain outlets of the plant's No. 5 and No. 6 reactors that stabilized Sunday in so-called ''cold shutdown.''

The bad news is not only in immediate proximity to Fukushima: "Iodine-131 19.1 times higher than the limit was also detected Wednesday afternoon in a sample taken some 16 kilometers south of the nuclear power station, up from 16.7 times on Tuesday."

[Contribution] What is Happening in the Reactor Cores of Fukushima Dai-ichi Nuclear Power Station?
24 March 2011
, by Michio Ishikawa (Chief Adviser of Japan Nuclear Technology Institute (JANTI))
http://www.shimbun.denki.or.jp/en/news/20110324_01.html

Excerpt:

When their temperature reaches about 900°C (1652 °F) , they react with surrounding steam and cladding tubes begin oxidizing.

Because this reaction is a strong exothermic reaction, the temperature around such cladding tubes locally increases when oxidization begins.

When the temperature reaches close to 1,300°C (2372 °F), the reaction accelerates and the increase in the temperature of cladding tubes cannot stop.

As a result, the outer surface of cladding is covered by thin oxide films (zirconium dioxide), and the inner surface of cladding tubes also creates the same oxide films by taking away oxide from fuel pellets (uranium dioxide).


In other words, the inner and outer surfaces of cladding tubes are covered by thin oxide films, and zircaloy alloy as the material of cladding tube is sandwiched between them.

It should be noted here that the melting point of oxide film is higher than the melting point of zircaloy, i.e., about 1,800 °C ( 3272 °F), as the material of cladding tube.

Therefore, the sandwiched zircaloy melts and flows down between films to form a puddle.

On the other hand, the inner and outer oxide films stick to each other and are crimped by the reactor pressure onto fuel pellets.

If it is likened, a fuel rod looks like a mass of pellets wrapped by polyethylene wrap.

As the oxide films are strong at high temperatures, even if a fuel rod deforms a little, it keeps sealing radioactivity and standing upright above the water surface.

This is the reason that radioactivity did not leak from fuel rods exposed above the water surface in the accident at the Fukushima power station.

It is no wonder, and it is not an error of measurement, either.


This condition changes at the moment when water is added into a reactor core.

The oxide film becomes brittle when the temperature decreases.

Moreover, as the film cools down and contracts, a fuel rod is divided at the boundary of pellets,

and drops to pieces (not melting)
and such pieces accumulate in the water in a state like a toy box upturned.

They can accumulate in the water because fuel rods under the water surface are sound.

These are the conditions that happened in the reactor core at the time of TMI accident.
