Slow response to the nuclear crisis, admits Japan

A week after the earthquake and tsunami that caused a nuclear crisis, the Japanese government admitted slowness in responding to the disaster, and welcomed the growing support of the United States hoping to avoid a complete fusion power plant in Fukushima Dai-ichi. While the death toll from the earthquake and subsequent tsunami on 11 in Japan increased to seven thousand 197 people, the whole world was on alert, watching for any evidence of increased radioactivity dangerous spread of the installation of six reactors, or that damage to the Japanese economy could cause a domino effect across the globe.

The missing and get to the 10 thousand 905 people, and despite the rescue in the town of Kesennuma, in the province of Miyagi, the hope of finding more survivors are slim. However, the miracle came when a young man was found alive under rubble eight days after the tsunami that devastated the northeast of Japan.

Rescuers found the survivor under the rubble of a collapsed house in Kesennuma (Miyagi Prefecture), one of the cities hardest hit by the double disaster. The boy was hospitalized in shock. The radioactivity contingency remains serious, the Science Ministry said that radiation levels at about 30 miles northwest of the Fukushima Dai-ichi plant rose at a time on Friday to 0.15 millisieverts per hour, roughly the amount absorbed in a X-ray chest.

Although the levels fluctuate, the radiation in the most points at that distance from the facility have been much lower than that. The Ministry does not have an explanation for the increase. A group of 99 people, comprising relatives of Mexicans and other nationalities, arrived in Mexico City on a flight chartered by the Government from Japan in crisis by the earthquake and tsunami of last week over the nuclear disaster, the Foreign Ministry Mexican.

A total of 80 of the evacuees are Mexican citizens and 19 foreigners are immediate family members, said Daniel Hernandez, director of the Department of attention to Mexicans abroad the Foreign Ministry, told reporters in the capital's airport. Among the foreigners there are "16 Japanese, one Chilean and one Peruvian china." An unknown number of Mexicans and left Japan on scheduled flights after the disaster began on 11 March, while others have indicated their intention to stay in the country, explained the Mexican Embassy in Japan.

The embassy estimated two million Mexicans were in Japan at the time of the earthquake. The plant, in principle, withstood an earthquake of magnitude 9. The three reactors were in operation automatically turn off and launched the emergency cooling. But an hour later, the tsunami damaged the diesel generators that cool the core.

When a plant is left without refrigeration, the uranium is heated and, together with the metallic elements can be fused into a highly radioactive magma. If it has happened or not in Fukushima was yesterday unknown. The Japanese agency said that most likely would have occurred in reactor number three, but no measuring instruments.

Not necessarily. If the containment building around the core holds, the magma would be inside. Yesterday, the International Atomic Energy insisted that the containment buildings were undamaged. Initially accident has been described as level four (on a scale of zero to seven). Chernobyl, in 1986, was a seven and Harrisburg in 1979 five.

Along with the reactors has been one three paths hydrogen explosions. When you release pressure lowering gas leaks out, inter alia, hydrogen. This is a gas which in contact with oxygen in the air, it explodes. That is what has been part of the reactor building. No, say experts, who argue that over time lose reactor temperature and slowly away from catastrophe.

There are 54 nuclear sites in 18. The atom marked the last year 29% of the country's electricity. The country has 127 million inhabitants, is the third largest economy in the world and has no gas, coal or oil. All that, plus its position as an archipelago, which makes the energy supplies from abroad, made them opt for the nuclear path.
