Japan announced a first step to restore electricity in Fukushima

Japanese engineers have managed to connect an external power cable to the reactor 2 of the Fukushima nuclear plant, but have not yet returned the flow of energy to the plant, as reported by the International Atomic Energy Agency. The IAEA has added is to "reconnect power to the unit 2, after spraying water on the reactor building of Unit 3 is complete." The return of electricity would be a positive step in starting the pumps to the cooling system of the complex that was damaged after elterremoto and tsunami of last Friday, Efe reported.

The Japanese government fight against the clock to prevent a merger of the reactor cores in central Fukushima. The latest information released by the Japan Atomic Energy Agency say the reactor 4 is in "serious complications." Meanwhile, the IAEA has said that the situation in the damaged reactor remains "very serious" but has not worsened since yesterday.

Japanese military helicopters and trucks to throw tons of water hoses on the nuclear power plant to restore the level of water in cooling tanks that store the spent fuel rods, which represent the greatest risk to produce a radiation leak mass to the atmosphere. The nuclear plant was seriously damaged during the earthquake measuring 9.0 on the Richter scale and resulting tsunami that occurred on Friday last week in Japan.

The government says three of the six reactors at the facility are in a relatively stable. Tokyo desperately tried all day to cool the facility with helicopters and water cannons directed from tankers. While the Japanese experts try, one after another, different solutions, the regulator of nuclear energy in the United States warned of the possibility that the tank to cool the spent fuel rods from reactor No.

4 has been dried and another tank leaks. Japan said the U.S. plans to fly at high altitude drone aircraft on atomic complex to determine the status of the situation, saying that Washington had offered to send nuclear experts. Gregory Jaczko, director of the Nuclear Regulatory Commission, told a parliamentary hearing that the levels of radiation around the reactor tank was very high, which is deadly risks to workers who are still struggling from the wreckage of damaged buildings the series of explosions in central since the earthquake.

"It may be very difficult for workers to emergency equipment close to the reactors. The dose (radioactivity) that could experience could be potentially lethal in a very short period of time, "said Washington, reports. The Japanese atomic agency said it could not confirm if the water still covered the bars.

Tokyo Electric Power (TEPCO ), the company that operates the plant, said Wednesday that he believed that the tank still had water, and warned that his priority was the No. 3 reactor tank, on which yesterday were thrown from helicopters about 30 tons of water. The aircraft dropped 7,500 liters of liquid in each of his four flights.

The day before, attempts had failed due to the high level of radiation. Two of the four releases of water made yesterday amid strong wind, were unsuccessful. The reactor 3 is the most dangerous because it contains plutonium rather than uranium. The plutonium isotope is very dangerous because it can cause cancer even if ingested in very small quantities.

TEPCO said the bulldozers were trying to clear the way to the plant allow fire trucks approach the reactors and use hoses to cool the facility. The Tokyo government has urged the population is less than 30 miles from central rather than out to the street, although the U.S. has told its citizens living within 80 kilometers of the area to leave or stay inside of buildings as a precaution ", which reveals the differences between the two countries.

The U.S. government has been careful not to criticize Japan, which seems to be overwhelmed by the crisis, but has given clear signals that it has severed ties with its Asian ally of the dangers of the situation. United States has issued more stringent security measures to those announced by Japan and has made warnings that contradict reports that Japanese are more optimistic.

Jay Carney, a spokesman for the White House sought to minimize the gaps between the two allies, and said U.S. officials were making their recommendations after analyzing the data independently of them come from the region. "This is what we would do if the incident was happening in America," he said, reports the Associated Press.

The central problems of Fukushima and other plants have destabilized the Japanese power grid to the point that forced rolling blackouts in some areas of the city and caused problems for some financial services. Mizuho bank said all its ATMs in the country failed twice during the day due to an excessive number of transactions in some branches.

The prospect of a major nuclear disaster has diverted attention from the situation facing hundreds of thousands of people have been affected by the earthquake and tsunami, and who are in refugee camps in difficult conditions. Latest estimates put the death toll in the disaster in nearly 15,000 people, of which 5,457 are officially confirmed dead and 9,508 missing.

Many of these will never be found, as some bodies were possibly washed away during his retreat to the sea and others may be buried under the mud. The Pentagon said the troops who are working on relief efforts for the victims of the tsunami can only come within 80 kilometers of the plant with permission.

Soldiers receive radiation pills before entering areas where radioactivity is likely to be in the worst nuclear disaster the world has suffered from Chernobyl in 1986.
