Japan struggle to control nuclear reactors in Fukushima

The plant operators Fukushima, affected by the earthquake in Japan, said on Thursday again use military helicopters to spray water on the affected reactors, after leaving the first attempt at the increase in radiation levels. While the authorities struggled to contain the nuclear crisis with a variety of options, health experts said the panic over radiation leaks at the plant could displace Daiichi potentially more dangerous threats for survivors of the earthquake and tsunami on Friday, as the cold or access to drinking water.

Yukiya Amano, the agency head of the UN nuclear watchdog, meanwhile, said that although it is not accurate to say that things are "out of control" in Japan, the situation is "very serious", with critical damage in three units plant. A series of warnings and reports on the crisis in Japan specialists and officials around the world put pressure on U.S.

markets, with the three major stock indexes back hard. Traders were glued to the screen, pressing the sale every time gave officials gloomy statements on the situation in Japan. The main U.S. nuclear regulator told the Congress that the radiation levels in affected Japanese nuclear plant could lead to lethal doses of radiation emergency workers.

"We think around the site of the reactor there are high levels of radiation," Gregory said Jaczko, director of the Nuclear Regulatory Commission. "It will be difficult for emergency workers close to the reactors. The doses may experience potentially lethal doses would be in a very short period of time," he added.

The Japanese government said that radiation levels at the gates of the plant were stable, but in a sign of being overwhelmed, asked private companies to help distribute supplies to tens of thousands of people evacuated from areas surrounding the complex. Bulldozers trying to clear the way to the reactor, located 240 kilometers from Tokyo, so that fire trucks could access and tried to cool the facility using hoses.

"People would not be in immediate danger if it came to these levels. I want people understand this, "said Yukio Edan chief of staff in a televised news conference, referring to those who live outside an exclusion zone of 30 kilometers. The high radiation levels prevented a helicopter flew to the area to throw water on the reactor number three (the roof was damaged by an explosion and where steam was out first time) to try to cool their fuel rods.

Executives at Tokyo Electric Power Co. said shortly after midnight (15:00 GMT) they would ask the army to make a second attempt later on Thursday. The operator of the plant described the reactor number three (the only Daiichi plutonium used in its mix of fuels) as "priority." The plutonium, once absorbed into the bloodstream, can persist for years in bone marrow and liver and cause cancer.

The situation in reactor number four, where the fire was declared, was "not good", said the operator of the plant, while water reactors threw five and six, indicating that all six reactors were installed now in danger of overheating. "Pour water in the pools of reactors number three and number four is a high priority," he told a news conference Hidehiko Nishiyama, an official of the Agency for Nuclear and Industrial Safety in Japan.

He added that the pool for spent fuel rods from the reactor was heating up three, while the four reactor remained a concern. "It could be a serious problem in a few days," he said. The Red Cross is appealing for money from the account. For the time will not be installed collection centers for donations in kind by the high cost would represent the movement of goods to the affected areas in Japan.

Beware of websites that provide mechanisms for donations. Security agencies warn that could result in fraudulent campaigns. The Mexican Red Cross is the only institution authorized by the Embassy of Japan to manage aid to daminificados by the earthquake and subsequent tsunami that killed thousands in China.
