The first nuclear power plant in Fukushima was damaged in the fuel pool Unit 2

Fukushima nuclear power plant accident in the first Toukyoudenryoku April 18, take the water from the overflowing water in the tank from the Unit 2 spent fuel pool, announced that it has detected high concentrations of radioactive material. That might have damaged the fuel stored in pools. TEPCO announced on April 17, the roadmap for the convergence of the accident, showed a 6 - to stabilize the primary goal after nine months, if there is a new fuel damage, the difficulty of the convergence plan might be. According to TEPCO, the water collected on April 16, cesium-137 becquerels of cesium 134 and 150,000 of the 160,000 becquerels per cubic centimeter, iodine-131 detection of the 4100 Becquerel. Most would not normally be detected. Damaged or spent fuel pool, which is considered to be leaking into the tank of radioactive material from nuclear reactors. Meanwhile, the Ministry of Economy Nuclear Safety Agency April 18, in the basement of Unit 4 reactor building, presentation and found a depth of 5 meters of water entrapment. Water has accumulated in four or tsunami, that there is a possibility that the inflow of water from the adjacent Unit 3. NISA also examining the amount of radiation in the reactor building on April 17 by moving the robot by remote control, the No. 1 to 10 mSv per hour at 49 and 28 mSv per hour at the No. 3 Datsu 57 or announced. Dose limit for workers in a nuclear accident in the Fukushima No. 250 mSv per year if 57 mSv per hour, run over four and a half hours. NISA is still very difficult tasks in the building, which hopes to devise a lower dose. According to TEPCO, the amount of radiation in the reactor in operation is usually about 0.01 mSv per hour.Dosimetry advanced robotic TEPCO reactor in the No. 2 most likely a high dose.To recover at an early stage of the reactor cooling is required to work within the reactor building, is a focal point of the dose in the building.Meanwhile, TEPCO for the transfer of accumulated high levels of contaminated water wells and building stand out No. 2 turbine building, water leakage countermeasure advanced centralized waste treatment facility in which to store.

The emergency safety measures 15 meters in the nuclear power plant expected tsunami night Hokkaido Electric Power

The first nuclear power plant accident by Hukuzima TEPCO, Hokkaido Electric Power Nuclear Safety Agency will be submitted to the Ministry of Economy, Trade and Industry in April 2011 a nuclear power plant safety for night emergency. Assuming 15 meters tsunami that struck the first nuclear power plant in Fukushima include plans to deploy a reserve aircraft and motor generators and pumps to move 31 meters height above sea level. Fukushima No. 1 nuclear power plant, and all power failed and the emergency diesel generators and nuclear facilities outside wearing a tsunami 34, no longer operate the equipment used to cool the reactors and spent fuel storage pool. As a result, hydrogen explode, are expected to have been released into the atmosphere large quantities of radioactive material is damaged reactor. Given this situation, the ministry on March 30, for power companies to secure supply, heat removal capability and ensure the reactor's emergency safety measures to develop six fields and securing spent fuel storage pool cooling ordered. Three primary night, but in more than 10 meters above sea level along the coast, when the tsunami hit 15 meters, could damage the emergency diesel generators are installed each with two reactors each. Therefore, first deployed on a hill to go to one car generator already March 18. In case the pump motor failed and the reactor cooling water is circulated and also put a reserve aircraft to the new heights.
All power is even more unusable because the water pump equipped with an auxiliary steam power, and Hokkaido Electric Power has 冷Yaseru fuel rods in nuclear reactors. Stopped all supplies also stopped working when the fuel storage pool cooling spent in cool water with two fire engines.
Other long-term as a measure, or build a flood barrier in the grounds of the ocean side of the reactor building, and also consider giving work to prevent flooding at the entrance of the building. Hokkaido Electric Power can not be cooled properly reactor to make scattering radioactive material shall not "have to, experts have also pointed out such measures should be taken safely withstand the tsunami of 20 meters.
Apart from this Hokkaido Electric Power Institute under the direction of security on March 15, until May 16 to submit improvement plans for an external power supply.

Says the limits of the fight against contaminated water Hukushima first nuclear power plant workers

The first nuclear power plant in Fukushima workers said the man Toukyoudenryoku subcontractors continue to work removing radioactive contamination of the water. Vicious circle in more polluted water injection to cool the fuel rods. Health workers, struggled in the field and energy are close to the limit, said a downright bitter sense of futility.Get soaked with sweat just to stay still. Yesterday, I dressed like this go to the bathroom too long and waiting 11 hours, including transfer.Double, triple-dressed cucumber and socks, and rubber gloves, a mask covering the whole face. Enervate the ironically it protective clothing to protect themselves from radioactive contamination.The forward base 20 kilometers from the field J is also included in the radiation controlled area village, are required to wear protective clothing when moving from.Centered around the No. 2 man, the underground contaminated water accumulated in the pit and turbine building stands, we are working to transfer hose installation and centralized waste treatment facility in the condenser pan. Work area has been distributed to each subcontractor.Initially, the dosimeter was paid enough now three to one. High-risk cases, but what would be considered a failure to wear two at a time, a weird reverse. Radiation dose, but the site has dropped gradually in the building where there is locally high.Put the hose to work underground contaminated water trapped in the turbine building, the site inaccessible to high radiation doses. He tied a rope to the hose Thus, down from a height 15 meters.On the other hand, be nowhere in sight because recovery of the cooling system has been working in parallel with the coolant. I think more polluted water irrigation and water to leak out. The vicious circle, which is not visible. Workers also began to be transported to the hospital sick from fatigue.Men on the day the earthquake, once they escape into the first primary. Returned to the scene late March at the request of the company. To work with the primary refuse to speak plainly when asked has been engaged for nearly 30 years.

Safety Agency, the water level rose again in the tunnel, Unit 2 nuclear power plant contaminated water Hukushima

Nuclear and Industrial Safety Agency Ministry of Economy, Trade and Industry at a press conference Monday April 14, once the water level has come down on the transport of contaminated water in the trench near the high concentration of 1 Unit 2 nuclear power plant in Fukushima and came back again revealed. Occasional water points are 7 am April 14 at 93.5 cm from the edge, rising less than 4 inches to 6 pm sometimes points the previous day. The turbine building of the underground water level has not changed. Transfer to the condenser work was completed at five o'clock in the afternoon of April 13, was transporting about 660 tons so far. NISA has not advanced in a transfer from the centralized waste treatment facilities under the influence of condenser water stop construction, and can not afford only to transport 700 tons of the total capacity of about 3,000 tons of condenser, showed difficulties in working condition. Situation continues to remain uncertain.

From Unit 1 to Unit 3 of Fukushima Daiichi Nuclear Power Station, a plurality of coolant line

Nuclear Safety Agency, METI am April 14, a press conference in Toukyoudenryoku Fukushima Daiichi Nuclear Power Station, it must be stable in the reactor coolant even after aftershocks within a few days 1 showed that the injection of the No. 3 line multiplexing.And are now prepared to use another tank, maintenance of multiple lines, starting from April 14 to test water injection.Meanwhile, TEPCO at a press conference April 14, has implemented measures an interruption of aftershocks, the tasks to increase dual external power to run pumps water injection equipment items, announced it would end by April 19 . Also working to relocate and avoid the loss of power in the tsunami heights, truck and emergency generators were placed 10 meters above sea level, the same reactor, Unit 1 reactor coolant 3 Three trucks loaded with 20 meters above sea level began to prepare to transfer to the pump - 30 meters away.Has been detected from the water and radioactive iodine at a spent fuel storage pool at Unit 4, about some of the fuel rod damage is suspected, NISA does not seem so large and damage. This data alone whether the melting was not determined. The pool water temperature was elevated to 90 degrees temporary, because the failure to detect the full capacity of the device, and may have been insufficient volume of water injection Tuesday.Working on contaminated water tunnel No. 2 is transferred to the condenser until the evening of April 13, 660 tons, the water level has dropped six inches. Then again Monday morning, April 14 rose 3.5 cm.

Begin to move the generator started working as an external power multiplexing and aftershocks of the primary measures Hukushima 

TEPCO April 14, to combat an aftershock of a nuclear power plant in Fukushima and began working for multiplexing external power supply route. Ceased temporarily supply of external power in the earthquake of intensity 6 lower on April 11, happens to stop over about 50 minutes the injection to the reactor, they become a pressing need to develop a system for ensuring the supply of emergency or.Currently, external power supply or two at the side of Unit No. 3 and 4 have been supplied by different routes. Together these two supply routes, to work for a power plant can be switched. Even if such an earthquake off one power line, make an arrangement that can be powered back up the other route.As a measure tsunami heights move irrigation pumps for temporary emergency diesel generator and reactor. Unit 1 is located around 10 meters above sea level, both moved to the hill about 20 meters. The height of the tsunami that hit the East first Fukushima earthquake was about 14 - 15 meters. Currently, the emergency power switch to perform manually, and it is impossible if a tsunami warning, there is a problem that workers away from the scene. By moving to a hill near the generator building and Kaname Shigeru Isolation of refuge workers, aims to restore power quickly.

Referring to the No. 4 fuel rod pool NISA Fukushima nuclear power plant

Nuclear and Industrial Safety Agency Ministry of Economy, Trade and Industry at a press conference last April 14 because it does not finish the analysis on the detection of high radiation doses over the spent fuel pool Unit 1 nuclear power plant Hukushima 4 , said at a clear conclusion about the fuel rods are not damaged. Showed also the view that it can not determine fusion.He added when nothing is happening but a little lower, larger numbers will be broken, if you are larger. Speculated that it might become a form in most healthy.The cause was detected with high radiation doses can be considered various factors. There also came out from the original gas reaction before the earthquake, has been considered and the impact of radioactive material attached to the rubble.

The government had estimated in March that the risk of nuclear accident Hukuzima level 7

Chief Cabinet Secretary Yukio edano at a press conference on the morning of April 13, apparently was aware in late March that the risk corresponding to the seven-level scale international assessment the severity of nuclear accidents first Hukushima was. Regard had been recognized as of March 23, the Nuclear Safety Commission, less data was based on speculation, and it was confidently say. Said it had asked to be a reliable analysis.And the prospects for a level 7 finally explained that the Safety Committee received a report from the Nuclear Safety Agency and the Ministry of Economy, on the evening of April 11. Disclose all data that is the basis of speculation at the same time. An accurate analysis is a problem with the government's response showed no idea.

TEPCO were unloading spent nuclear fuel Hukushima

TEPCO April 13, for spent fuel at nuclear power plant first, Fukushima announced that the study started from a pool of fuel is unloaded outside the reactor building. When did you start from any Unit on which the transfer had not yet decided. TEPCO began to study why and explained that currently being considered as part of promoting the convergence of nuclear accident and recovery work.The No. 1 and No. 3, No. 4 because it is damaged the building, housed in a conventional manner to carry its own fuel containers may be difficult. And considering that the deal that formed a new pillar extraction methods and using the crane.

Aftershocks have occurred frequently large Fukushima nuclear power plant was recognized as the same level as the Chernobyl 7

Nuclear and Industrial Safety Agency of the Ministry of Economy, Trade and Industry April 12, the first nuclear power plant accident raised the INES Level 7 Toukyoudenryoku Hukushima the worst. Sign of convergence in the vicinity of No. 4 in the morning and also the fire that can not be seen April 12, Fukushima emissions of radioactive material could have been out over Chernobyl. Their plight is to add insult to injury, a series of aftershocks. On April 11 aftershocks struck the maximum intensity of lower 6 Fukushima and Ibaraki, intensity 5 lower in the event of an aftershock epicenter off the east coast as well Tiba am April 12. The agency assumes that the seismic aftershocks of the seven classes in the future. Level 7 is the same level as the Chernobyl accident and the former Soviet Union's worst nuclear accident. Nuclear Safety Commission, radioactive materials are released every hour or up to 10,000 primary Terabekureru first ever Fukushima, estimated it lasted for several hours. INES Level 7 has been defined as more than 131 becquerels Terra tens of thousands of iodine emissions equivalent to the outside, it also decided to apply to NISA. Meanwhile, deputy head of the nuclear location of TEPCO Matsumoto Zyuniti full release of radioactive material has not been stopped, but comparable to the Chernobyl emissions, and expressed the view that may exceed or have concerns or. Among such, around 38 minutes at 6:00 am April 12, there was a fire in the No. 4 nuclear power plant near the first outlet. Building fire in the sampling location, mobilizes fire brigade, was confirmed extinguished at 9:00 am every 12 minutes. Was not injured. According to TEPCO, the roof of the building by eliminating the sampling in the tsunami, that there is a possibility of leakage from the battery state was exposed. The prospect of the first primary convergence Hukushima still stand. To add insult to injury is the critical situation, but a series of aftershocks. Epicenter and magnitude Hamadori Fukushima received 7.0 aftershock on April 11, the director Satoshi Osamu Doi Earthquake Prediction Information Division Japan Meteorological Agency has pointed out in an interview. M7, 8-class earthquake, the aftershock activity is reduced in about one month, and this large scale M9. For shallow inland earthquake aftershocks, it is also assumed to be seven seismic shaking. On this day, the Earthquake Research Committee of the Government, the chairman Abe Katsuyuki abroad, for earthquake East M9, but the earthquake class, near Japan M8 recognition had been some time in belief of the maximum level showed. Unexpected great earthquake seismology in authority are more than common sense in the scale of the aftershocks of the Society. In fact, the warnings issued by the Meteorological Agency has a track record of Mr. Doi. 7 days prior to the earthquake in a month's time being, said intensity 6 lower - can not deny the strong likelihood of six major aftershocks. The six-strong aftershock struck a maximum intensity around Miyagi Prefecture, was at midnight that day.
M8 likelihood of some class.
The most worrying about the aftershocks of the April 11, Mr. Sono Doi is a place that has occurred. Iwaki City inland observed intensity is less than 6, which brought East this earthquake, it was nearly 30 M4 region is not happening in most earthquakes. It was a very large earthquake for earthquakes, so that widely influenced state of the crust. Cautioned there may be outside the influence of strong aftershock tremors. M7 class so far has occurred in the aftershock area, all land is the first time. Intensity 7, outside the aftershock land, the key word that crosses horror scenarios epicentral earthquake in the city. At the same time, the Fukushima No. 1 nuclear accident, large aftershocks and tsunamis hampered their work, there is concern that the situation may worsen. Aftershocks shake someone up living in the metropolitan area, and nuclear power plants. When will I fit together ... and everyone would think. However, looking at the huge earthquake in the past, but the reality is that the aftershocks of the class going over the big earthquake occurred many years later.Occurred on December 26, 2004, earthquake off Sumatra triggered tsunamis M9 · 1, the 28th of March 2005 three months after a 6 M8 · aftershocks occurred. The tsunami caused a few meters, 1,000 units of casualties. The Sumatra is also the 12th September 2007 M8 · 5,2009 between the M7 has 10 years of aftershocks have occurred four times the level earthquake. Among seismologists, the aftershocks have been small scale and a common sense of the magnitude of main shock. M9 · this main shock for 0, M8 can cause aftershocks have a good class. Incidentally, the Kobe earthquake of January 17, 1995 M7 · 3. How to know how large the earthquake. The largest earthquake aftershocks in the East, took place about 30 minutes after the main shock was 7 M7 ·. However, Mr. Doi of Japan Meteorological Agency can be evaluated at the largest aftershock of this earthquake has not said.

High levels of contaminated water to begin transfer operations

Accident at a nuclear power plant Fukushima Daiichi TEPCO to work to move the condenser water contaminated with radioactive material concentrated behind in the tunnel known as trench No. 2, on March 11, 2011 is expected to begin.The Fukushima Daiichi nuclear power plant is a large amount of water was found contaminated with high levels of radioactive material from a trench in the turbine building, I also become a source of high radiation doses. Has become a way of working towards the recovery of the nuclear power plant cooling. TEPCO polluted water accumulated in the trenches of Unit 2 is a first discharge for the high concentration, particularly using the pump Kumi上Ge policy is transferred to the Unit 2 condenser. Under the direction of the country so that all possible safety considerations, there is no mosquito net 10 days to crack the condenser, during a transport emergency, and had to check if the response from a leaking hose . Work in the morning is over 11, work will begin as soon as ready. In addition, the level of Unit 2 trenches since stopped the outflow of contaminated water into the sea of ​​high levels of 06 to 13 cm rise by 7:00 am on December 11, height 91 cm from the surface to the ground has become. TEPCO, the situation now is full of carefully monitored as there continues. In addition, it has become contaminated water accumulate high levels of "centralized waste treatment facility" from the process of releasing contaminated water into the sea in relatively low concentrations, the release date according to the 9070 t 10 you're done with you, but make sure that no water is left. Meanwhile, No. 1, to avoid in advance the risk of hydrogen explosion, they were continued 11 days the task of injecting nitrogen gas into the containment, so far, abnormalities such as temperature and pressure of the reactor, he said is. The work is scheduled to begin August 11, called silt fence provided cover to reduce runoff of radioactive materials into the sea near the Unit 2 intake of contaminated water had flowed.

Nuclear accident can not see a convergence month

Month has passed by since the accident on March 11, 2011 in Fukushima Daiichi Nuclear Power Station Electric Power Company.
Work towards the restoration of cooling the reactor is essential for the convergence of the situation, as I think of going is blocked by water contaminated with high concentrations of radioactive material, even they remained murky clues convergence Masu.Fukushima Daiichi nuclear power plant has become a Yasenaku lost all power reactors in eastern Japan on March 11 earthquake last month, the government, Nuclear Emergency declaration for the first time that has ever become a serious problem.Although water injection is done to cool the reactors and spent fuel pool is also on March 10, which radioactive materials are released to the outside now, the situation continues to remain uncertain.This month for the convergence of the situation, the result was continued hard work trying to restore the function of the cooling power is restored from the outside, the fresh water to cool the nuclear reactors and fuel pool at the temporary pump is ready to inject a stable posture.However, the result was injected large amounts of water, water is contaminated with radioactive material in high concentrations likely leaked from the reactor, and the basement of the turbine building, and things build up inside a tunnel, called a trench outside the building making.Dzukezu to the location of pumps and piping necessary to revive the stable reactor cooling system to prevent contaminated water and this is not so much state and determine if any damage or injury today.Prospects for recovering the cooling function, Deputy Director-General of NISA Nishiyama Hidehiko the Ministry of Economy, on Monday morning at a press conference There are a few ideas for each reactor, it can be in such a form stage show clearly that there is no policy.'s order would stand but that prospect a few months, not that there is no clear, he said.Treatment of contaminated water that interfere with work, and ensure your reservoir does not go as you wish and are ready to send the water hose laying.10 days, as the treatment of contaminated water series is scheduled to begin at last to work into the condenser water from the trenches of Unit 2 will be the first, the treatment of contaminated water in high concentration is expected to more than 50,000 tons of at least prospect is not standing, and continues to be impenetrable even convergence clue.

Accident at TEPCO's Fukushima Daiichi nuclear power plant because it has hindered recovery operations with high doses of radiation out of the building debris blown around by a hydrogen explosion, TEPCO, heavy equipment moving in the unattended now begin in earnest with the removal of debris. The primary Fukushima Daiichi is littered with debris blown off the walls and roof of the reactor in hydrogen explosion occurred in the No. 3 and the No. 1, depending on where the measured radiation dose as high as Siebert mm hundreds per hour and that has hindered recovery efforts.Toukyoudenryoku do this afternoon on April 10, will begin in earnest to the task of debris removal in moving heavy machinery for construction, such as radio and bulldozers shovel.Operation is executed so remotely located control room looking at a few hundred meters from the video camera was installed six fixed cameras and attached to heavy machinery near the site.The radio does not reach the places is that tap into the operating room and covered with a movable radiation shielding such as lead.According to TEPCO, debris was removed, since it might have been contaminated with radioactive material concentrated, and stored at the site of the primary into the container, to be strictly controlled.
