The latest information confirms that the 1, 2 and 3 reactors at the Fukushima Daiichi nuclear power plant is fully melted in just a few hours after the earthquake.
Senior politician Ichiro Ozawa in the Wall Street Journal interview expressed the assumption that because of the situation at Fukushima whole country could become uninhabitable.
The melting of the atomic nucleus is excessive melting of nuclear fuel to the point where the core is damaged, poured out, and is a threat of a powerful release of radiation into the atmosphere. However, the "penetration" of the nucleus is even worse scenario in which nuclear fuel literally proplavlyaetsya through the bottom of the damaged reactor, and could potentially proplavitsya through the outer shells straight into the ground, in the air or water.
In the report suggests that penetration has occurred, which must be confirmed by the IAEA, "the first official recognition of the" difficult situation, says the Japanese Daily Yomiuri. It also confirms that suspicion of such an outcome, have been from the beginning, as confirmed by further reports that a powerful reactor accidents led to the formation of holes in the damaged tanks, and that the radioactive water, and possibly nuclear fuel leaked into the lower reservoir.
The IAEA has said that the accident at Fukushima at least is as serious as the Chernobyl disaster, but on the basis of new information suggests that it is even worse. At the moment it is unknown whether the leaked out were assembled in the lower tank of fuel with the potential to poison the ground water and cause extensive damage.
In the interview, which was preceded by a new report, Ichiro Ozawa said that areas around Fukushima are already completely "uninhabitable." He also suggested that the present form of bo? Most of the country including Tokyo, could suffer the same fate, if not taken proper steps to correct the situation.
http://mixednews.ru/Japanese nuclear emergency operator, "Fukushima-1" will start on Friday experimental pumping water through pollution control equipment to be charged with the main hope for cleaning highly water accumulated in the lower floors of the units and turbine compartments station Kyodo news agency reported.It is planned that water treatment will take place in several stages. Water will be consistently cleaned of oil, then, using a zeolite (inorganic silicate, which is a natural absorbent) will be decontaminated, and the last stage will desalinate. Purification of the radiation levels will be reduced to 10,000 times. After cleaning, the water will be re-directed to cool the reactors. Will be cleaned daily 1.2 thousand tons, and by the end of the year will be 200,000 tons of purified water. Costs amount to 53.1 billion yen (663 million dollars).For experimental pumping water to be used with low radiation.As calculated by the Company, in the event of a successful experiment for June 15-17 will probably start cleaning and high-level water.At present, the station has accumulated 105,000 tons of highly radioactive water. Its volume is 500 tons daily updated by the water used to cool the reactors and spent fuel pools.After the earthquake and tsunami on March 11 at the plant "Fukushima-1" was recorded a series of accidents caused by the failure of the cooling system leak radiation, residents were evacuated from the 20-kilometer zone around the plant.
Greenpeace calls on the Japanese government to evacuate children and pregnant women from the city, located 60 kilometers from the nuclear power plant accident in Fukushima, writes The Australian. The reason for concern, "green" — a high level of radiation.The organization claimed that their own data on the radiation situation in Fukushima approximately coincide with the official data the Japanese government. The problem is that on the basis of these figures are made entirely different conclusions — especially regarding the threat to children's health.The appeal requires Greenpeace "to provide full financial and logistical support to the evacuation of children and pregnant women in areas with high levels of radiation and organize full decontamination of contaminated areas."Organization's head Kumi Naidoo visited a kindergarten in the city not far from Fukushima, where the parents in the home to remove the top layer of soil. After this visit, Naidu said that the local people are facing a nuclear disaster or a catastrophic shortage of information.From the moment the accident occurred at nuclear power plants, Japan has officially raised the maximum permissible limits of radiation for ordinary people, including children, from 1 to 20 mSv per year. This is equal to the dose allowed for nuclear industry workers."This is unacceptable, — said at a press conference in Tokyo Energy Department Greenpeace representative Jan Beranek. — After the Chernobyl accident, the Soviet government decided to evacuate people from all corners of the annual dose is estimated more than 5 mSv."In light of this, the Japanese government simply has no right to insist that 20 millisieverts — safe dose. 20-kilometer exclusion zone around the plant is not enough, said Beranek.In the city of Fukushima now adults and children receive a dose of 10 to 20 millisieverts per year — only with air. The particles that are easily inhaled or swallowed by the dust with water and food, shall not be considered.Radiation experts agree that children are most at risk. A growing body more vulnerable. Cancer and other diseases threaten him more.
Stop Other Japanese nuclear power plants because of the accident at the nuclear power plant "Fukushima-1" will create serious problems for the economy., Said here today the Minister of Economy, Trade and Industry Banri Kaieda.
According to him, "the situation of energy supply can dramatically complicated if other energy companies, particularly in the west of Japan will not be able to run during the earlier stopped for routine prophylaxis reactors." Kaieda pointed to this possibility in his speech at today's ministerial meeting. Now According to the Ministry of Economy, more than 30 out of 54 of the country's reactors do not work in conjunction with the regular technical inspections or work suspended after the March disaster for work to improve the level of protection against possible attacks of powerful new element.
As previously reported in this department, in April 2012 in Japan can stop all of the reactors, as the exploitation of many of them very actively support local governments. In such a scenario, it is believed in the ministry, the country will have to spend an additional annual $ 40 billion for the purchase of oil and natural gas for thermal power plants.
After the earthquake and tsunami on March 11 in Japan, except for 6 reactors "Fukushima-1" on the Pacific coast of Honshu island was stopped several nuclear power plants, including two neighbors — "Fukushima-2", "Onagawa" — and the largest nuclear plant "Hamaoka" in Shizuoka Prefecture. Therefore, the real power reactors operating in the country now stands at only 36 percent of the total nuclear energy potential of the country.Salvage Japanese nuclear power plant "Fukushima-1" has started preparations for the opening of the double doors of the building of the 2nd reactor to reduce the level of radiation there and humidity.
This was reported today, the power company, "Tokyo Electric Power" / TEPKO / — operator station.
This operation, the implementation of which is scheduled for the second half of this month, will create conditions for the resumption of repair work inside the building unit. "Right now, the liquidators of the accident — note in TEPKO — can not be located in the premises of power, even for a short period of time due to excessive humidity, reaching 99.9 percent." This is difficult as the use of industrial robots, cameras are out- for accumulated vapor mist. Excessive moisture, according TEPKO, despite the efforts of the nuclear power plant operator, the steps persists for several weeks, due to the release of hot steam from the damaged lower part of the reactor and the fumes from the water in the pool to cool the spent fuel rods . air in the building is also an urgent need to deactivate using special air filters to reduce the current level of radiation is about ten times.
Complex TEPKO similar works with government approval in Japan performed on May 8 in the building of the first reactor. Before they were informed of the start of the regional authorities and neighboring countries.Salvage Japanese nuclear power plant "Fukushima-1" began the final stage of testing a new installation for the decontamination of highly radioactive water, work is scheduled to start on June 15., Reported today the power company "Tokyo Electric Power" / TEPKO / — operator station.
The commissioning of this complex and costly complex will again use clear water to cool the reactors, which will reduce leakage from the damaged reactors. In the lower areas, "Fukushima-1" and related technical wells already accumulated more than 105 thousand tons of liquid with radiation levels above 1 thousand millisieverts per hour. TEPKO in fear that the water from the "underground lake", which is replenished daily by about 500 tons gets into the ocean for 20 June. If the rain intensified, it could happen in five days earlier.
To avoid this scenario, TEPKO plans daily cleaned of radioactive substances around 1.2 tonnes of water. All with the help of the new installation is expected to deactivate up to 250 thousand tons of water, and the precipitate with radiation levels above 7 thousand millisieverts per hour will be at least 2 thousand cubic meters. This swill will initially be stored in temporary containers at the reactor building, and then it rebooted into a more robust underground tanks, which will be built at the plant by the end of the year. Because of the very high radiation that all operations should be carried out remotely.
But in TEPKO admitted her representative, yet do not know how in the future will be disposed of deadly clots of mud. There is no clarity regarding scattered after the explosions of hydrogen throughout the plant debris is now being loaded into containers for up to 4 cubic meters and stored in the zone along the aisles station. The current Japanese law does not allow nuclear waste with such high radiation, noted in TEPKO, and in Japan there is no large-scale enterprises for the recovery and long-term storage. The number of victims of the catastrophic magnitude 9.0 earthquake and tsunami that devastated northeastern Japan on March 11, exceeded 15.4 thousand people. This was reported today by the National Police Agency of the country.
The official death toll from the disaster is 15,401. Missing persons are considered 8146, but the authorities plan to soon recognize their dead, to begin compensation. As detailed in the 18 prefectures of 2.4 thousand temporary shelters are still around 91.5 thousand Japanese.
The damage caused by the disaster the country, according to the authorities, more than 25 trillion yen / 308 billion dollars /, and the restoration of damaged areas may take up to 15 trillion yen / U.S. $ 184 billion /. In addition, not less than 11 trillion yen / 133 bln / can be estimated losses from the accident at the nuclear power plant "Fukushima-1".
