Japan on alert for a possible meltdown in two reactors at Fukushima

Barcelona. (Writing / Agencies) .- Japan continues nuclear alert, immersed in "the worst crisis since World War II" in the words of the prime minister, Naoto Kan, has comprecido to urge the Japanese to "overcome this setback and create a new Japan. " Khan has hailed the recovery and prosperity of Japanese society with other adversities of the past and has said he has confidence in its citizens.

The head of the Japanese state has warned that cuts are expected electricity supply, especially in Tokyo - as a preventive measure in the country have closed 8 of its 55 nuclear power plants, which means that 25% of energy production has stopped. Risk of nuclear fusion Prime Minister sends this message of encouragement as the country fears a possible merger at the core of two reactors at the Fukushima 1 (Fukushima Daiichi).

The reactor 1 an explosion occurred yesterday and two more reactors of the same plant, the numbers 2 and 3, do not stop rising temperature because the earthquake on Friday overturned their emergency cooling systems - like that of other reactors this plant and four of the Fukushima 2 --.

The recovery of power so they can effectively cool a key to that there will be a second explosion due to accumulation of hydrogen. The water level in the reactor has decreased in recent hours to uncover three meters of fuel rods, which causes it to emit radiation in the vicinity of the nuclear plant operated by Tokyo Electric Power Co (TEPCO) above the safe limit.

The company explained that there is an "emergency situation" but, according to his analysis, does not pose an immediate threat to health. Emergency crews working at top speed in these two Japanese plants to try to cool and lower the pressure inside the reactors involved by the release of steam and the supply of sea water.

The tasks involve, logically, many risks and the IAEA has already reported that a worker has died and at least eight more have been injured - four of them in the explosion yesterday -. The Japanese government has admitted that the situation is complicated and it is "highly likely to have initiated the merger process," although the Japanese chief executive secretary, Yukio Edan, pointed out that part of the core could "warp" and That does not amount to a "merger." The situation is very confusing and Edan recognizes that at this time the government did not Purdah "verify what happens in the reactor core, but they are taking" measures based on this hypothesis.

" And is that a core meltdown would be the worst case scenario to occur, and as part of the reactor exploded, the consequences for those affected by radiation may be similar to those affected at Chernobyl in 1986. On that occasion, however, the facility did not have a container that withstood heavy pressure and the material inside the reactor was thrown in all directions, causing an expansion of radiation, which had a deadly effect on all the region.

It so happens that Fukushima, active since 1971 and the oldest in the area, had received permission to operate at least until 2021. Radiation three times higher than permitted from Friday Fukishima 1 is radioactive gases emanating from abroad. For a few hours were released in a controlled manner to reduce pressure inside, thus avoiding an even greater disaster, no clutch, to the explosion of fumes yesterday far exceeded the safety limits.

The Government has admitted that just after the explosion, the level of radioactivity in the area was placed three times above the permissible, but ensures that is now at lower levels. It is estimated that the evacuees at the perimeter of the two plants - which yesterday was extended first to 10 km and then to 20 in Fukishima 1 - could be around 200,000, but around the country about 400,000 people.

Mask fitted with fear in the body some of these evacuees have queued enabled centers to ascertain whether levels of radiation present. To protect the population - an estimated 160 people who may have been exposed and there are 22 confirmed irradiated - the government has prepared capsules of iodine, a chemical element that mitigates the effects of exposure.

International aid has begun arriving at the place of catástrife. From Manchester and 63 experts have come to support 2 dogs and Germany is preparing to send troops. The Japanese Nuclear Safety Agency described the incident as level 4 on the scale of atomic events (INES, ranging from 0 to 7).

It is the most serious since the accident since Chernobyl atomic (Level 7). 2,300 people dead or missing in Japan struggles to contain the nuclear threat as the death toll left by the earthquake and tsunami on Friday - which alert was lifted today - is growing. The authorities' official count is 2,300 people either dead (1217) and missing (1,086) and 1,683 wounded, according to U.S.

broadcaster CNN. However, the data is provisional, since only the shore of Miyagi prefecture, one of the most affected, nearly 10,000 people unaccounted for after an entire people, Minamisanriku, was nearly destroyed by floodwaters.
