Two Years of Fukushima Boiling [Todays Pictures]

Well it's happening again, massive amounts of steam / fog covering the reactor buildings at Fukushima. Good thing there are people in the chat that brings it to attention when it happens. I took the opportunity to take some pictures of the boiling reactor buildings.


I also looked at some old pictures I had taken two years ago in August 2011 and if we have a look at those pictures things have not really changed at all. Sure there might be less fires and spectacular lightning going on now, probably due to the fact that the melted reactor fuel corium have now gone very deep underground. But there still is the steam events taking place on a regular basis over at Fukushima.



This is an old video from 2011.08.04 showing some of the events going on. Notice how Tepco turn the camera to black and white at the 1 minute mark to hide away the things taking place. It really starts to pick up at about 1:40 min into the video.


I have to say that anyone who claim the contamination taking place (about 400 tons of radioactive water per day into the Pacific Ocean) that comes directly from molten nuclear fuel corium in contact with groundwater that say somehow it is "diluted and safe" is a MADMAN!

Fukushima Vs Atom Bombs - Putting Things In Perspective

Hi folks,

I read a comment on enenews talking about the amount of radioactive material stored at the Fukushima nuclear plant and how this compared to the Hiroshima and Nagasaki bombs. I have had this in the back of my mind for quite some time but other events taking place have put me off from doing a post about this. Well now is the time.

Lets start with how much radioactive material is stored at the Fukushima nuclear power plant. Actually it would be more correct to say how much was stored until the explosions at the Fukushima nuclear power plant. Because reports show that Plutonium and spent fuel along with other radioactive material have scattered around the plant and the surrounding area.

The spent nuclear fuel:

Reactor Building 1: 50 tons
Reactor Building 2: 81 tons
Reactor Building 3: 88 tons Uranium / Plutonium (UO2/MOX)
Reactor Building 4: 135 tons
Reactor Building 5: 142 tons
Reactor Building 6: 151 tons
Common Spent Fuel Storage Facility located at ground-level: 1,097 tons Uranium / Plutonium (UO2/MOX)
Dry Storage also located at ground-level: 70 tons

The reactor unit cores contain less than 100 tons of nuclear fuel.
Numbers given by Marvin Resnikoff, a radioactive waste management consultant.

Now lets put things in perspective. Little boy the nuclear bomb dropped on Hiroshima had 150 lbs Uranium-235. While the nuclear bomb dropped on Nagasaki, the Fat Man contained 13.6 lbs Plutonium-239.

Both bombs leveled the cities Hiroshima and Nagasaki and brought great destruction to the Japanese.

However Soviet Union's most powerful 50 megaton Tsar bomba the biggest nuclear bomb ever made weighed 27,000 kilograms (60,000 lb).

The explosion of the Tsar Bomba put out the equivalent of 1,400 times the combined power of the two nuclear explosives used in World War II the bombs that destroyed Hiroshima and Nagasaki. Little Boy (13–18 kilotons) and Fat Man (21 kilotons). Tsar bomba alone had 10 times the combined power of all the explosives used in WWII. And one quarter of the estimated yield of the 1883 eruption of Krakatoa.

But still the 27 tons of radioactive material in the Tsar Bomba is nothing compared to the amount at the Fukushima nuclear power plant. It’s hard to try and imagine but I hope these numbers will give you a little more understanding of the situation.

Intense Fire and Smoke at Fukushima Reactors

UPDATE:
☢ Fukushima Spectacular Fire Lightning Burning Steam Daiichi Nuclear Power Plant Reactor Units September 03 2011 ☢

Related to:
☢ 6.8 Earthquake Hit Japan With Epicenter off Fukushima Prefecture Very Quiet At Reactor Units Since☢
☢ Fire and Smoke at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE ☢

First off I would like to thank all of you who write on the chat and share links. I appreciate that.

After the 6.8 earthquake hit Japan this Friday the Fukushima Nuclear Plant have been quiet. With quiet I mean there were no signs of the flashes of light along with fire and smoke afterwards at nighttime. So I, like most of you that have been watching the plant came to the conclusion that TEPCO now halted the burning of radioactive materials on site. It was only a matter of time before they would start back up again.

Well it didn't last long until they started back up. And they did it big time. There have been some very intense fires and lights going off at the reactor units this night. The fires and lights hasn't been this intense since June I think.

I'm not going to embed any video in this post, I'll post the links to the video. Instead I will show you screenshoots I took of the fire and lights.

I think this last video is interesting to watch. How they stop at morning before they have turned the camera back to color. You can really see how the light fades away and at 4:50 Local Time sharp the camera is no longer in black and white.
2011.08.22 04:00-05:00 / ふくいちライブカメラ (Live Fukushima Nuclear Plant Cam)

This picture show you how fast they stop the work. In about 30 min at morning. The first picture is taken 04:20 Hours and the other at 4:50 Hours when they switched back to color. The light that you clearly can see on the night black and white picture is now very faint.

I also noted a strange series of flashes going on to the left side of the screen at 20:26 Hours.




Don't know about you but I get this urge to cover my ears watching the videos.

Massive Amounts of Steam Video During Daytime at Fukushima

UPDATE Prof. Christopher Busby:
☢ Tokyo Radioactivity Extreme Sample Higher Than Chernobyl Exclusion Zone ☢
UPDATE RT NEWS:
☢ Radioactive Steam Escaping - The Ground at Fukushima Facility is Cracking ☢
I did a post earlier about this
☢ The Reason Behind the Fog at Fukushima Daiichi Nuclear Reactors ☢

11:30 Local Daytime on August 14 2011 the Fukushima Daiichi Nuclear Reactors Units were again engulfed in fog. What makes this video special is it's during daytime. So we really get so see the steam coming out from the reactor units this time.

The crane is at work and in the beginnig of the video we can clearly see the crane working. By the end of the video though, the crane has almost disappeared in steam. There have been that same flashing light going on these last couple of days also, so this could also mean that this is the Common Spent Fuel Storage Facility that's blowing steam. Then by the end of the day there were some more steam going out at 18:00.

Cigar-shaped Object Over Fukushima UPDATE ☢

Related to:
☢ Cigar-shaped Object Over Fukushima Daiichi Nuclear Reactors on Aug. 9 2011 ☢
UPDATE: ☢ The Moon Over Fukushima Daiichi Nuclear Plant Aug. 11 2011 ☢

The Cigar-shaped object was back on Aug. 10 2011. I was not quick to write about this because I wanted to have a good look at the footage taken.

Like laste time it first appears a bit before 18:41 and also like last time disappears around the same time 20:43. The Fukushima Live Cam goes black and white like always and this thing moves across the screen. Not exactly the same path as last time because it disappears before the end of the screen. I would say somewhere over reactor unit 4.

We cant rule out any construction work, because TEPCO now plans on building a large Chernobyl like cover over the reactors and the work should be underway.
☢ TEPCO will build a Chernobyl Like Cover Over Reactor Units ☢

We cant either rule out an reflection but I think it's odd that the reflection only appears at that same time a bit before 19:00 and then moves across the screen to go out at 20:40.

If you really look close at the number 1 picture (still in color) you also see that the "reflection" also have a bright dot overhead. I think it's odd also becaue it seems to be very bright.

Cigar-shaped Object Over Fukushima Reactors


With my previous posts like ☢ Strange Lights Flicker at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ and also ☢ Strange Fires at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE 3 ☢

And not to forget the post I made earlier today ☢ Fukushima Fires Continue with Lightning and Thunder Aug 8 2011 ☢ You might think that this situation with the Fukushima Nuclear Reactors can't get much more stranger than this right?

Along came a cigar-chaped object..

Watching the live cam at just before 19:00 hours local time, a strange light appears in the sky above the Fukushima Reactors. Before the camera goes black and white (like always) the object appears. It's a very thin Stripe at first, but as the object moves across the screen it gets brighter. It's goes on and off several times. Appears and then disapperars but follows a path across the screen. It first shows up in the middle of the screen at 19:00 and then by 20:40 it has move the the right side where it disappears out of view.

I thought at first maybe this have something to do with the crane or that this is a reflection of some kind. But I can't really tell for sure. Looking at the daytime video we clearly see that the crane arm can't extended to the other side of the screen. This object have not been seen before to my knowledge on the site, and it continues to glow, disappear and appear. To me it looks like it passes between the towers, that would place the cigar-shaped object path over reactor 3 and the Common Spent Fuel Storage Facility. Tell me what you think.

Strange Fires at Fukushima Plant UPDATE 3 ☢

This is a follow up on the earlier:
☢ Strange Fire at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE 2 ☢

I got some good comments about my last post trying to pinpoint the location of the Fukushima Fires going on. Some have put forth a very dark theory about what is happening. They claim that the Centralized Radiation Treatment Facility (area located behind the reactor 4 building) is in use to burn radioactive material on site. Another teory would be that they have built a facility next to reactor 3 to do the same. Burning radioactive waste sounds crazy, but the sad thing about this is that it is in use all over the world. There have been actions against this to little effect. Because it is considered safe when they use $200.000 filters made in Germany to capture the "fallout".


I can't say for sure this is what's going on because the location of the fires are still to me in the same area as the Common Spent Fuel Storage Facility. Looking at the pictures there is a hill in the background. If we take this hill and the tower drawn out in red into reference then to me it looks like the fire is in that area. But it's hard to say for sure, and with news of how radioactive material is indeed being burned around the world. Who knows what they really are up to. One thing is for certain, something is burning at the plant.

Why Fukushima’s “spent” fuel rods will continue to catch fire

By: Kirk James Murphy, M.D. Tuesday March 15, 2011 4:26 pm


Six of the spent fuel rod pools  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 up to 3450 fuel rod assemblies.  The common pool holds up to 6291 fuel rod assemblies.  [The common pool has windows on one wall which were almost certainly destroyed by the tsunami.]  Each assembly holds sixty-threefuel rods. This means the Fukushima Daiichi plant may contain over 600,000 spent fuel rods.  The fuel rods once stored atop reactor 3 may no longer be there: one of the several explosions at the Fukushima reactors may have damaged that pool.
Now that we have partial meltdown in the reactor vessels – the part of the reactor where nuclear reactions are supposed to happen – in at least three of the Daiichi palnt’s six reactors, why bother with swimming pools for fuel rods?  Simple. Even after they are no longer usable to drive nuclear fission in the reactor vessels, the “spent” fuel rods are still highly radioactive.  Part of that radioactive energy is emitted as heat.  That’s no surprise: heat from radioactivity is the how the reactor core vessels generate the heat that drives the nuclear plant’s turbines to generate electricity.  The fuel rods don’t know whether they are in the core or in the pools: they keep emitting heat and radioactivity until the radioactive material decays into non-radioactive elements.  That process can take years, which is why spent fuel rods are still dangerous years after they leave the reactor core.
How can we prevent the spent fuel rods from bursting into flame once they’re out of the reactor core? The Fukushima plant – like many other reactors – keeps the rods in water, which absorbs the heat energy.  But the pools – like the water in a teakettle – will boil away unless new water is added.  After the Fukushima plant lost power in Friday’s 9.0 earthquake and got hit by the tsunami, the plant was no longer able to keep the pools topped up.

Strange Fire at Fukushima Plant UPDATE 2 ☢

New UPDATE 3 of this post:
☢ Strange Fires at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE 3 ☢
Other wierd things happening:
☢ Cigar-shaped Object Over Fukushima Daiichi Nuclear Reactors on Aug. 9 2011 ☢

I have done some investigating on the Strange Lights / Fires going on at the Fukushima Daiichi Nuclear Reactors. Trying to pinpoint the location at the plant where from the strange lights are coming from.

From my earlier posts you can watch the videos of the fire and smoke captured on the live cam Aug. 6 2011.
☢ Fire and Smoke at Fukushima Daiichi Nuclear Power Plant Aug. 6 2011 ☢ UPDATE ☢

The pictures I got from the video shows something going on. This was Aug. 6 2011. At about 19:00 Local Time. The exact same event also took place at the exact same time on Aug. 4. 2011. And also today there is a glow coming from the area at night. This is followed by a thick fog at morning hours that make the reactors disappear. And like always like clockwork the image goes black and white, a few seconds after 19:00. But before it did, we can clearly see something what looks like a fire is starting.

The question is where is this. Well I used Google Earth to try and get a better view of the area. Not sure where the live cam is placed but I think the angle is pretty much the same.


The red drawn is where the towers are on the map. And from what is seen on the live cam the circle show us the area from where the fire is coming. I put in some yellow lines where the light would come from and cast a shadow on the reactor buildings. Notice that there is a mountain / hill before the area. This would mean the light from the fire captured by the live cam would not be as bright. And could mean that the fire is much bigger than what is shown.


If we have a look at the map of what buildings are in the area of the fire we see that behind the hill is the Common Spent Fuel Storage Facility. I can only draw the conclusion from the images seen and video of the fires and smoke that there are some serious problems at Fukushima right now. All the fog / mist that comes and goes also would indicate that they are trying to cool the fuel rods and don't have much luck with it.

I also wonder when they are reporting.
"The No. 3 reactor is consuming nearly three times the coolant water that the No. 1 and No. 2 reactors are taking to cool down their fuel rods, as a considerable amount is missing the target."

"The amount of water pumped in daily to maintain the temperatures at these levels is about 216 tons for the No. 3 reactor, as opposed to 84 tons for the No. 2 reactor, which is about the same size and contains roughly the same number of fuel rods, and 91 tons for the No. 1 reactor, which is smaller."

What if this missing water is used to cool the Common Spent Fuel Storage Facility? If so by the looks of it there would be some 100 tons of radioactive steam going up into the air daily.

Geiger Counters - Radiation Detection Meters - Handheld Radiation Detector



When it comes to radiation detection meters you really have a wide field of gadgets to choose from, however radiation detectors are the most common to use. First of all if you need to know what type of radiation you are looking for. There are Alpha, Beta and Gamma radiation detectors. And also there is neutron emission of nuclear radiation. And all these different types of emissions have radiation detectors for a specific type of radiation that you can buy radiation detector for. Some also measure both Alpha and Beta. Others detect Alpha, Beta and Gamma. While others let you measure Beta and Gamma radiation.



What most people have use for though are Dosimeters you can buy a handheld radiation detector pretty cheap that are good addition to a survival kit. There are different kinds that you can use that will detect radiation. There are radiation badges that will tell you when radiation become high. Workers at nuclear power plants use these to inform them of how much radiation they have been exposed to. Now also children in the Fukushima prefecture have each been given a radiation badge so they know if they are exposed to radiation. Some come in the shape of a pen that you can carry in your pocket while other are made more compact so that you can attach them to your keychain. And then you have what is called a personal radiation monitor. These are also called Dosimeters and also normally called Geiger counters. Although not all use the Geiger-Muller Tube for the radiation detection some use a semiconductor instead. These and mostly the older geiger counters seen are pretty big to carry around, so they might not be best suited for a survival situation where you only need to carry the most important things. However if you have land and want to check radiation around the property and drinking water then these are the geiger counters to get because they are very well built units.

These are the once that you normally see people use. They have different units of radiation detection, because when it comes to radiation there are many standards used. some give the measurements in Rads, while other use Sieverts. Some have the maximum radiation value for the measured radioactivity quite low but they will still give you an idea of the amount of radiation in the area. With the units ranging from between background radiation 0.001 mSv/hr all the way up to 10 Sv/h. Normally a dosimeter will measure radiation in micro siverts per hour. If you were to walk into one of the reactor units at the Fukushima Daiichi Nuclear Plant you probably would get an error reading from your dosimeter because the radiation levels are so high there.

Note that some places outside the exclusion zone in Fukushima that are too radioactive for people to live in have areas where the radiation levels are above 30 Sv/h. So if you are in a area that have high radiation the radiation detectors would also there go off the scale. However Geiger counters or radiation detectors are still favored as general purpose alpha/beta/gamma portable radiation detectors and radiation detection equipment, due to their low cost and robustness. Most come with an LCD Display that show you the radioactivity in the area. Nowdays you will even get alarm sound and the possibility to connect the device to a computer. Either with a Infrared, Bluetooth or USB connection.

So if you look at the radiation detectors for sale that have this, then these radiation detection meters will allow you to make maps of contaminated areas that show where the radiation is high and low. This also will help you to see which areas are becoming more contaminated over time. With several nuclear reactors in the US and around the world located near fault zones that makes it a danger if a big earthquake would hit the area there is always a good choice to have a radiation dosimeter avaliable. I'm sure many in Fukushima would have been grateful to have dosimeters avaliable at the time of the disaster and I am sure you to would be grateful to have a geiger counter handy when you need one.
