☢ Melted Nuclear Fuel Corium Soon Outside Containment at Fukushima Reactor Units ☢

New reports coming out saying that all of the nuclear fuel at reactor unit 1 have melted and broken the bottom of the steel pressure vessel inside the reactor. The corium (melted nuclear fuel) is now on the bottom of the concrete below and is eating it's way down further and soon it will reach the containment vessel steel that is the last defence before completely outside. 

Reports say that not only is this happening in reactor unit 1 but also in Unit's 2 and 3. In the light of this it has again shown the seriousness of the Fukushima Disaster.

The melted nuclear fuel in reactor unit 1 have already eaten it's way 65cm into the concrete below and have another 37cm left before it reaches the containment vessel steel.

In Unit 2 and Unit 3 it is estimated that 63% and 57% of the nuclear fuel have melted outside. The situation is serious and with this new information there are doubts in my mind that workers can continue to work close the the reactor units for much longer. Radiation readings outside the reactor buildings are already high. 

This is a confirmation that radiation levels are high even outside the reactor buildings. There are reports done from Yoichi Shimatsu that radiation levels outside the Nr. 2 reactor building to be 1000 millisieverts or 1 Sieverts per hour.

We also hear from Henry living in Japan about 100 km from the Fukushima Daiichi Nuclear Power Plant that news is highly controlled and he show us a video from a private owned television channel showing 300 microsieverts on camera when reporters where allowed to take a bus tour outside.

Unit 1 fuel melting erosion 65cm
November 30, 6:19 minutes

Accident at Tokyo Electric Power Co. Fukushima Daiichi Nuclear Power Station, Unit 1 fuel meltdown occurred, the substantial fall in the amount of containment of the reactor by breaking the bottom of the steel melt the concrete bottom of the vessel estimated to be 65 inches maximum erosion has revealed the results of TEPCO.Some fuel for Unit 2 and Unit 3 has been estimated that fall into the containment vessel, has again highlighted the seriousness of the accident. 

For Unit 3 from Unit 1 of Fukushima Daiichi nuclear power plant is going to melt fall meltdown of nuclear fuel, but was seen as falling into the molten fuel from the reactor containment vessel, some more than eight months from the accident Even after the situation is not known for more. 

Multiple research institutes and national TEPCO about it, different ways to analyze the state of the molten fuel from the reactor temperature and injection situation obtained so far, 30 days, resulting in open country Study Group announced. TEPCO's analysis of this evaluation was the most severe cases, for Unit 1, burn all the fuel has been estimated to have dropped considerably in the amount of containment break through the bottom of the reactor. The store has a concrete bottom of the container, and further covered with steel plates. 

Falls to the bottom of the vessel containing the fuel, in the sense that this concrete erosion and melting reactions in the heat, the worst case, has been estimated to reach to a depth of 65 cm in Unit 1. At the most concrete thin, with only 37 centimeters until later that no containment, has again highlighted the seriousness of the accident. Also, Unit 2 and Unit 3, the worst case, the fuel burn of 63% and 57%, respectively, has been estimated to have been part of it falling into the containment. 

According to TEPCO, the temperature of the containment vessel and the reactor is now 21, has not been below 100 degrees both fuel melted and is cooled by water, erosion of the concrete was evaluated and has stopped and. Study group is also presented another analysis of this research was to discuss the state of the reactor and fuel on multiple results. TEPCO and countries to further analyze the results of this analysis, we have decided to consider how and whether to retrieve the decommissioning of nuclear fuel for the future. 

NITE Nuclear Safety, Mr. Seiji Abe, technical advisers, the results of TEPCO's analysis, "and I do not think it is wrong, yet have taken that first step. Results can be derived only one answer I can not. the future is different stacking analysis, we need to analyze the reality of the accident, "we said.

☢ The Radioactive Chat ☢

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.
