Alarm at Fukushima nuclear plant due to increased radioactivity

Japanese officials today expressed alarm over a possible fracture of the core of one of the reactors at the Fukushima nuclear power plant issue, which has increased levels of radiation in the area. Officials from the Nuclear Security Agency of Japan raised the possibility that there is a more severe radioactive contamination, while continuing to work to evacuate residents living near the plant in Fukushima Prefecture.

Recent data on activity in the reactor 3, which is the greatest damage appeared after the earthquake of 9.0 magnitude on the Richter scale caused a tsunami just two weeks ago, indicate that limited damage may have occurred. Speaking to the press, a UN spokesman said the water with radiation may come from the reactor core, so it "can not rule out" that you damage the containment vessel but insisted "it is premature to offer conclusions" .

The operators have been struggling to keep water cool in the pool where are the fuel rods from the reactor after a powerful tsunami that caused the outage of electricity in the plant and its cooling system damaged. Japanese engineers working at the Fukushima nuclear plant made public that the reactor water 3 reveals radioactive contamination rates 10 000 times greater than normal.

The news comes as the authorities ordered the implementation of new emergency procedures in the area to speed the evacuation of people who remain within a radius of 30 kilometers. On Thursday, two workers were hospitalized after their feet exposed to contaminated water without adequate protective boots while trying to restore power in the reactor 3.

Fukushima operators, with the help of firefighters from Tokyo and Kawasaki City, on Friday resumed bombardment of water in the reactors 2, 3 and 4, while trying to resume the cooling systems. Residents of areas near nuclear power expressed concern that access to services has been restricted and there is a growing fear when exposed to high levels of radiation, so they begin to feel isolated.

The Minister of Defence, Toshimi Kitazawa, announced Friday that U.S. armed forces next week will provide tons of fresh water to be pumped into the reactor and try to keep at a low temperature. Kitazawa said the U.S. authorities have insisted that they use fresh water instead of sea water because the salt causes corrosion of the equipment at the nuclear plant.

In the Japanese capital, the lack of bottled water and food shipment interruptions left empty shelves after two weeks of the earthquake and tsunami. The unusual view of shortages in one of the richest and most modern capital of the world came a day after officials in Tokyo reported that the radioactive iodine in drinking water of the city recorded more than twice the level considered safe for children.
