Some gas doesn't... but we'd still see way more thermal damage. That said, if there was no electricity then what would ignite it? Corium could, just there is no oxygen underground.

Perhaps we saw a non-ignition methane blowout occur at #4?

Occams razor says it's either that or a fresh fuel load melting down.. or both.

I'm still catching up from 1st of march.. bear with me!

You forgot the roots of Daiichi - our venerable old #1.

They had to start somewhere to make bombs, they needed a reactor first - the rest came with. South side where the other reactors would be built, have some interesting additions.

lurking as usual, but this pic is messing with my head!

Supposedly taken from ~4 kms out @ 300m altitude.

The obvious is R2 being MIA (or better: MDM - missing during meltdown), but there is other stuff too:

1) There's "reverse" perspective going on WRT the turbine buildings... They seem to get bigger the further away they are? R1 TB is tiny compared to R3 TB. Overhead shots show they are basically the same size.

Man can only see 3d for a few meters as our eyes are not very far apart. Probably why I find 3d films a bit over the top sometimes. When using a large telescope style lens arrangement, this is compounded. Everything looks like a paper cutouts through those types of optics.

2) The R1/R2 exhaust stack location is messed. In real life, the stack is between R1 + R2. In this shot, it appears to be closer to the camera than R1 and in front of the red/white crane which in turn is infront of R1.

Appears to be exactly where it should if you reference the drone photos or various flyover videos. The top down (looking down the stacks) drone photo on cryptome will help you see this clearly.

3) That red gantry crane directly behind the R3/R4 exhaust stack. Appears to be the same general area as the one in the previous pics with "blue things" and the robotruck, however, the sizes don't match at all. In the pics where it's loading the truck, the crane appears to be approx 3.5x the height of the truck. The one in the above shot is way taller! Also, it appears to be turned 90 degrees from the previous shots.

as per #1 answer

I don't get it, but something just isn't right about this pic...

Well hey GR. Yeah I didn't know how to save film at the beginning so it's just my early screen caps. It disappeared fast. A drive down reactor road on March 16th 011. There are a few more in my files, that are here somewhere. [Ask Q] He's got the keys to the ats dungeon.

By the way, that 1967 fuk film, where your screen cap came from is gone too, but there are a few screen caps in file #1 also. His channel was scrubbed. I sent him a note asking what happened? No response.

I'm not a EPA chart wiz, but if 5 is normal and Hawaii hit 190, isn't that 38 X normal plutonium?

Communications from the Wilderness Underground

Very much wanted to post chaps 9 and 10 at one time, but 10 is taking much too long, so here is nine.

Have no touch with current situation as book has now become all consuming. Hope all is well.

Today is the first day of the rest of the 60's revolution.

zLove from zworld and the Wilderness Underground

page between chaps 8 and 9

Compare the official version of 'another hydrogen blast and nothing to worry about' with the following;

“Unit 3, Fukushima – this was no ordinary explosion. There has been a chain reaction of uranium and plutonium. That’s all been blown out. But no one does measurements. I believe the government does not want to have them done. Not only Tepco is lying – even our government is concealing the truth.”

Mr. Haneda, Tepco worker who was at the Fukushima nuclear power plant when R3 exploded.

"In the Reactor 3 explosion, there was a flicker of fire, then a vertical, black smoke up the reactor building. A hydrogen explosion does not produce such a black smoke. And the mushroom cloud. It resembles a nuclear explosion."

Mr. Setsuo Fujiwara, Japan Nuclear Energy Safety Organization (JNES). Mr. Fujiwara was a nuclear plant inspector until the spring of 2010.

It should be noted that Mr. Fujiwara both knew Fukushima Dai-ichi and had access to the data that has never been released or even revealed by Tepco and the government. Like the actual cam feed of the R3 blast, showing how high the cloud rose and how long it actually lasted for.


Chapter Nine
The Four Stages Of Apocalypse

It was obvious to many nuclear engineers, scientists, and weapons experts on that windy March morning that the explosion at R3 was not a product of hydrogen, and involved something that resembled a low yield nuclear explosion.

However, since that time this theory has fallen by the wayside because both reactor and SFP appear intact, and a prompt criticality nuclear explosion would have destroyed the vessel that contained the detonation. And if not from the RPV or SFP, where then.

In the following scenario, explained over the next few chapters, a nuclear explosion underground does not only appear possible, it is the only scenario that makes sense. As stated previously, by the time 11:01 rolled around on the 14th of March, all three reactor cores had melted down and were most likely through the RPV and into the concrete basemat below. It is also possible one or more cores had already made their way through containment.

The NRC stated the following at the time;

TONY ULSES:.."the bottom line is, you know, they lost all AC, so they lost all injection capability and they've been having trouble controlling their SRV (safety relief valve). And right now -- I asked them yesterday, what was the vessel pressure? And the guy told me it was at four megapascals, and all they got are fire pumps. And there's no way a fire pump is going to push against four megapascals....So we're concerned that they've been in the situation on and off really from the beginning and that they've been having trouble getting injection all along".

Without coolant it only takes between 20 to 100 minutes for boil off to occur and the fuel to be exposed. Once fuel is exposed, it only takes 5 minutes for melt to begin. Once melt begins, the temperature increase occurs at such rapid rate that coolant, through the means available to Tepco at the time, could not be added fast enough to slow down the melt. In fact, adding water at this time, after melt had started, could have had deleterious effects. For one, it caused the oxidization of the uranium and plutonium in fuel while creating the possibility of a flash steam explosion. It also caused the oxidation of zirconium which created significant additional heat from exothermic reactions, as well as producing large quantities of hydrogen available for ignition. And it created an environment whereby the fuel could achieve re-criticality.

That, and the fact that the Mark 1 is the worst type of reactor design for preventing melt down, and it is safe to assume that core melt was well under way long before the 14th. The following is from Casto, the NRC head rep in Japan.

"And, you know, if we end up with a molten core and then you talk about the time for the concrete to disassociate, you know, that NUREG says it’s a couple of inches an hour, you know. And, of course, that Mark 1 containment is the worst one of all the containments we have, and it’s literally, you know, this NUREG tells you that in a station blackout you’re going to lose containment......the one thing the NUREG doesn’t really do is tell you how to stop it, how to mitigate it, other than keeping water on it.....So, you could just about assume it’s going to go its course with the Mark 1.......the containment is probably not going to last at all".

Two inches and hour is a figure commonly used in the industry. However, there are conflicting data in NUREG reports concerning core penetration through the concrete basemat. In fact, two inches an hour may be a gross underestimate, as other NUREG data shows melt through of a Mark I RPV similar to Dai-ichi's occurring 100 plus minutes after the core is uncovered. Once in the basemat, core penetration occurs 15 hours later. This equates to 18 plus inches an hour penetration rate.

If the above simulation is accurate, or close to it, then Dai-ichi had at least one core, and possibly more, already in the ground outside containment. However, since both the NRC 2 inch estimate and the NUREG 18 inch estimate are simulations and not real life data, there is no way of knowing which might be more accurate for Fukushima. It is assumed that the NUREG 18 inch estimate is due to a corium/concrete reaction, and depending on the type of concrete used in the construction of Fukushima, this may or may not be possible there.

So for the following scenario we will take the middle ground, that all three reactor cores had penetrated the RPV, dropped into the basemat and were in the process of eating their way through the concrete and steel liner below, with the possibility of R1 already outside containment. The tunnels the corium created are plugged on top by a hardened corium crust that has cooled from exposure to water. There are also pockets of melted fuel that didn't escape the RPV or enter the basemat, and these too are being cooled within containment.

It should be noted that, being contained in the concrete below the RPV is actually a desired condition once melt down begins. In fact, there are designs being considered for future nuke plants that would have a corium breaking/cooling system built into the basemat, so that escaped corium will cool in the concrete, and limit the production of serious environmental effects after that point. Kinda like the emergency truck ramps you see on freeways in case the brakes overheat. Only here it's the core overheating. To 2800 degrees centigrade. Heaven help us should we ever consider a nuclear meltdown as one of those things you just need to prepare for like a loss of brakes.

The following is an analysis of the R3 explosion. As stated before, there were four distinct stages to this explosion.

Stage One

The first stage of the R3 explosion has never been acknowledged except by a few. The only visible evidence was a faint yellow flash/pulse that is seen on the original Oztvwatcher video, a video that has since been taken down, altered and put back up. However, the original can still be found occasionally in nooks and crannies on the web.

This pulse appears to be over either R1 or the switching yard and can be seen in the location marked below approximately 0.8 seconds pre blast.

There are still versions of the original out there, but if posted on the ATS forum site, they are soon replaced with a version that has been altered, or the link is dead. If you find one, in order to see the yellow flash/pulse you need to tilt the computer screen considerably to darken it, as these vids have been washed out from day one to hide any detail.

This yellow pulse was also seen by locals. Mr. Toshiyuki, a resident of Iwaki, about 50 km away from the Fukushima plant, said he saw a yellow flash a half second before R3 exploded. He was more surprised at the yellow light/flash than the explosion itself.

And there was one other indicator of this underground pre pulse blast. In the time between the yellow flash pulse and the fireball erupting out the southeast corner roof, R3 contracted 5+ feet. The following are from the frames just before, and as the blast initiates.

Stage Two

Stage two is the dragon's tongue, a fireball that ejects out of R3. Extreme heat bursts out the southeast roof, and the south, east and possibly north walls above the service floor. The fireball is most evident erupting from the southeast corner of the roof, but can be seen popping out of the cloud in other areas, indicating it's presence throughout the initial burst. Evidence points to a fireball emitting out the east wall at the same time as well.

And then this fireball gets sucked back into the structure just as quickly as it came out. It should be noted that the fireball is sucked back into the mushroom stem cloud that was now beginning to erupt and not the reactor building itself. The dragon took a deep breath.

Stage Three

This stage is the one that most have come to know as the R3 explosion. This is a black mass that is ejected straight up, indicating that it had been vectored through a barrel effect. It is inconclusive from the video where the mushroom stem cloud originates from due to the building already in an explosive cloud that is being driven by the wind. It appears to come from the left of the exhaust stack making it north of the PCV/RPV. This location is corroborated from post explosion evidence.

It should be noted that, during the fireball and at the beginning of this stage, the lower building and ground go into convulsions, contracting and expanding many times per second, before the mushroom cloud bursts out.

Stage Four

This stage begins 9 seconds after the vertical blast, and is seen as white columns of steam or smoke that radiates out from R3 (until the 12 second mark), and then straight up in vertical columns above the switching yard (SY). Between 10 and 20 seconds in there are numerous flashes of light that occur inside these erupting smoke columns. They appear to be electrical arching, but this doesn't make sense, as there was no electrical power (supposedly) coming in to the SY.

These columns of white smoke/steam come together and are driven by the wind back towards R3 and R4, and by the end of the video at 45 seconds in, have become the dominant contributor to the R3 blast cloud.

Theories Based on Illusions

There have been numerous theories put forth to try and explain the R4 explosion. Unfortunately, all of them are based on the detonation point being somewhere inside the reactor building, and none stand up to the light of day.

Other than Tepco's ridiculous explanation of a hydrogen explosion similar to R1, the two most common are a prompt criticality occurring in the SFP, and a steam or nuclear explosion occurring inside containment.

Neither works for numerous reasons, the easiest to understand being this. The primary stage 3 blast is vectored straight up, as if shot from a cannon. If this has been caused by prompt criticality in the SFP, it would eject from the SFP. It didn't. The same applies to an explosion starting from within containment.

But more importantly, when one analyzes the force of the blast, had it began in either the SFP or PCV/RPV, the detonation would have destroyed the structure that vectored it straight up. This did not occur.

This is especially evident when looking at photos of R3 post explosion. The area of roof above the concrete PCV plug is still intact. Had the focal point been underneath it, it would have been destroyed, like the NW and SE corners of the building were. This is basic physics 101. Had the blast emanated from containment it would have destroyed anything above it, and not left the roof beams intact.

Northwest by Northwest

All signs point to the stage 3 mushroom stem cloud having emanated from the northwestern part of the reactor building, (similar to R4's NW area and the black molten flow down it's flank), and it is this area that experiences intense fires over the next few days, and which are the focus point of all activities concerning R3.

When the SDF came in and first set up the water cannon truck to fight the fires at R3 on the 17th/18th of March, they knew where the fire was. They knew what needed water. They headed for one point and one point only. The following screen captures (from NHK videos no longer available) clearly show this intention. The first is from the afternoon of the 14th and shows smoke rising from the NW area of R3. The second is the SDF's first attempt to fight the fires. They set up to the side of the NW corner but can't reach the smoke.

Then as seen in the MOD video, they move closer and closer in to the NW corner before settling down right in front of it. A dangerous move, but what they deemed necessary at the time.

There should be no doubt as to where the R3 mushroom cloud came from. Or at least where it emitted from. The next chapter will explore the detonation point, and the different types of reactions that may have been at work.

Next: Chapter 10) Bombs Under Dai-ichi Or: How I Learned To Stop Worrying and Share The Pain.

Water level of Fukushima No. 2 reactor only 60 cm above bottom

TOKYO (Kyodo) -- The operator of the Fukushima Daiichi nuclear power plant on Monday found that the water level in the No. 2 reactor's primary containment vessel was only 60 centimeters deep when it checked the interior of the crippled reactor using an endoscope.

Tokyo Electric Power Co. spokesman Junichi Matsumoto gave assurances that the melted fuel inside the No. 2 reactor remains cooled through continuous water injection, as the water temperature in the vessel was 48.5 C to 50 C. But he acknowledged that the lower-than-expected water level suggests that a large portion of the injected water is leaking from the primary containment vessel, possibly via the damaged suppression pool that is linked to the reactor.

To specify from where the water is leaking, the company needs a ''broader inspection,'' Matsumoto told a press conference. TEPCO plans to conduct another survey into the No. 2 reactor Tuesday to check the interior radiation level.

Imo the interpretation that the Waterlevel is 60cm high
is not 100% accurate,
because there are two levels,
parts of the Corium is resting on the Saddle,
this is covered by (only) 60cm Water
but the Saddle itself is a few Meter above
the Wet-Well which is flooded with Water!

Probe at Japan's crippled nuke plant finds fatal radiation levels

Published March 27, 2012
| Associated Press

TOKYO – A new probe at Japan's crippled nuclear power plant has found fatal radiation levels and hardly any cooling water inside one of the reactors, renewing concerns about the plant's stability.

The operator of the Fukushima Dai-ichi nuclear plant says an endoscopic examination Tuesday detected radiation levels up to 10 times the fatal dose inside the No. 2 reactor's contain chamber, suggesting challenges ahead in shutting down the facility.

The probe also found the containment vessel had cooling water up to only about 2 feet from the bottom, far below the yards estimated when the government declared the plant's stability in December.

Plant workers also reported fresh leaks of contaminated water from a water treatment unit, some flowing into the ocean.

More quakes in Japan, and a couple of back to back 6.4's north of Onagawa. USGS only shows one.

I was digging around last night and found this film from last spring. It's marked Onagawa but it's monju, and I thought this might be the cause of the recently found plume model showing Tsuruga or Monju spewing?

At approx. 9:30 am on March 27, workers of the other company found the water leakage from the underground pipes (Anti-disaster pipe for Unit 4 transformer) during the removal work of such pipes using heavy machine to prepare the ground condition for the installation work of Unit 4 covering. After the inspection, it was confirmed that such pipes were already isolated and the leaked water was treated water remaining in the pipes. *Treated water (fresh water): water from the Saka#a Dam

At 12:42 pm on March 27, in the Unit 3 and 4 Service Buildings when a TEPCO member was bringing in analysis samples from Fukushima Daiichi Nuclear Power Plant, he confirmed that there was contamination by radioactive materials on a desk beside a small object monitor (non-controlled area*) at the checkpoint for the confirmation of contamination of goods for workers exiting from controlled area. Currently we are investigating the cause of the contamination. The contaminated desk and other spots where there is a possibility of contamination are partitioned and under control now. *Controlled area is the area which requires control for prevention of unnecessary exposure and prevention of increase of radioactive contamination. Non-controlled area is the area other than controlled area.

‘Fukushima reactor in crisis again’

TOKYO: A new probe at Japan's crippled nuclear power plant has found fatal radiation levels and hardly any cooling water inside one of the reactors, renewing concerns about plant's stability.

The operator of Fukushima Dai-ichi nuclear plant says an endoscopic examination on Tuesday detected radiation levels up to 10 times the fatal dose inside the No. 2 reactor's contain chamber

Chernobyl Cover Construction to Start in April

Ukraine will begin the construction of a new sarcophagus at the Chernobyl nuclear plant on April 26, the 26th anniversary of the world’s worst nuclear disaster, the country’s president Viktor Yanukovych said.
The Chernobyl sarcophagus will cost 935 million euro ($1.2 billion) to build. Most of the money was raised through a donation drive among the world’s governments held last year, with Ukraine only contributing 6 percent of the sum.

1 of Japan’s damaged reactors has high radiation, no water, renewing doubts about stability

The data collected from the probes showed the damage from the disaster was so severe, the plant operator will have to develop special equipment and technology to tolerate the harsh environment and decommission the plant, a process expected to last decades.

Tuesday’s examination with an industrial endoscope detected radiation levels up to 10 times the fatal dose inside the chamber. Plant officials previously said more than half of melted fuel has breached the core and dropped to the floor of the primary containment vessel, some of it splashing against the wall or the floor. Particles from melted fuel have probably sent radiation levels up to dangerously high 70 sieverts per hour inside the container, said Junichi Matsumoto, spokesman for Tokyo Electric Power Co. 2/03/27/gIQA83d0dS_story.html

This one mentions dark yellow sediment...believed to be fragments(ie: small pieces), peeling paint or dust - no problem there then!

Very high radiation, little water in Japan reactor

Video footage taken by the probe showed the water inside was clear but contained dark yellow sediments, believed to be fragments of rust, paint that had been peeled off or dust.

A probe done in January failed to find the water surface and provided only images showing steam, unidentified parts and rusty metal surfaces scarred by exposure to radiation, heat and humidity. Finding the water level was important to help locate damaged areas where radioactive water is escaping. Matsumoto said that the actual water level inside the chamber was way off the estimate, which had used data that turned out to be unreliable. But the results don't affect the plant's "cold shutdown status" because the water temperature was about 50 degrees Celsius (122 Fahrenheit), indicating the melted fuel is cooled.

Three Dai-ichi reactors had meltdowns, but the No. 2 reactor is the only one that has been examined because radiation levels inside the reactor building are relatively low and its container is designed with a convenient slot to send in the endoscope. The exact conditions of the other two reactors, where hydrogen explosions damaged their buildings, are still unknown. Simulations have indicated that more fuel inside No. 1 has breached the core than the other two, but radiation at No. 3 remains the highest. The high radiation levels inside the No. 2 reactor's chamber mean it's inaccessible to the workers, but parts of the reactor building are accessible for a few minutes at a time _ with the workers wearing full protection.
