Video of Melted Core at Fukushima Reactor 2 ☢

Fukushima Reactor 2 Melted Nuclear Core Video Corium China Syndrome
Fukushima Reactor 2 Melted Nuclear Core China Syndrome
This is a video showing the boiling / melting reactor core from Fukushima reactor 2. The corium is seen as a orange and sometimes light pink blob in the video taken.

I would like to thank FC in the chat for bringing this video to my attention and Nowi See on youtube who found it in the TEPCO archives and uploaded it to youtube.

Published on 27 Jan 2015 by Nowi See on youtube. You can also find the video in the TEPCO website archives if you like.

"This is the radioactive sludge and toxic water that they pretend they're doing something about. 40 minutes in underwater hell."




The Daiichi complex in Fukushima, Japan had a total of 1760 metric tons of fresh and spent nuclear fuel on site last year, according to a presentation by its owners, the Tokyo Electric Power Company (Tepco).

The most damaged Daiichi reactor, number 3, contained about 90 tons of fuel, and the storage pool above reactor 4, which the Nuclear Regulatory Commission’s (NRC’s) Gregory Jaczko reported had lost its cooling water, contains 135 tons of spent fuel.
  1. The amount of fuel lost in the core melt at Three Mile Island in 1979 was about 30 tons.
  2. The Chernobyl reactors had about 180 tons when the accident occurred in 1986.
Going by the reported amount Fukushima has nearly 10 times more nuclear fuel than Chernobyl.

It also means that a single spent fuel pool at reactor 4 has 75% as much nuclear fuel as at all of Chernobyl.

But in reality it gets much worse than that..

Tepco very recently before the disaster transferred many more radioactive spent fuel rods into the storage pools. According to Associated Press, there was at the time of the earthquake and tsunami some 3,400 tons of fuel in seven spent fuel pools plus 877 tons of active fuel in the cores of the reactors.

This all totals up to 4,277 tons of nuclear fuel at Fukushima at the point of the disaster.

Which would mean that there was almost 24 times more nuclear fuel at Fukushima than Chernobyl at the time when it went full meltdown only hours after the earthquake struck the plant..

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.
