ROME - The alarm on the central atomic Tokai, The third in two days, is partially reversed. But the attention on a reactor in Fukushima is very high. The three facilities are now all cooled with sea water and boric acid, accidents have caused the excess over the legal limit of radioactivity. Other failures have occurred in Onagawa in Miyagi area, then the alert on Tokai, just 120 kilometers from Tokyo, two cooling units out of three are out of order.
A very difficult day, in which the Authority has forecast Japanese alerted about the arrival of new tremors of magnitude 7, in which the country has thousands of dead and missing. Fukushima. The wound atomic Fukushima scares throughout Japan. After the loss of radiation due to the destruction of the cage containing a layer of the reactor, which caused the contamination of at least 160 people, opened a front containment even on the reactor 3, where the fuel rods were damaged.
"The situation remains serious," was said by the authorities. A technician died this morning, and Saturday, eleven people were injured in accidents that occurred at the Fukushima nuclear power plants in the area. Regarding the possible consequences, would stand the chance of an explosion.
It is not averted the worst case scenario, the most frightening: the meltdown, the "meltdown". That is a catastrophe. Japanese Prime Minister Naoto Kan said that "there will be another Chernobyl", but the damage suffered by the cooling of the 11 plants affected by the earthquake have spread rapidly.
Accidents from Fukushima to Onagawa. Fukushima, Central No. 1, reactor 1. After the earthquake, a chemical reaction caused the explosion of the cage outside the reactor containment. The blast occurred in the midst of a decompression procedure. The reaction involving hydrogen, but the steel container and cement remained intact.
As a measure of emergency cooling, seawater is pumped with added boron, to counteract potential problems. After the accident, the reactor 1, is number 3 to go into crisis due to failure of water to cover the fuel rods. To the point to check the hypothesis of an explosion, and even that of the merger, although the government spokesman, Yukio Edan has ruled out the scenario most feared by explaining that the temperature remains under control.
The big problem of the reactor 3, if an accident were to occur similar to the number 1, be the differences in power. Unlike the first, fed with normal uranium fuel rods, the number 3 works with a guy called Mox fuel made from a mixture of oxides of uranium and plutonium. In this case, the fallout could be two times worse.
After the number 3, the second reactor showed malfunction. Naoto Kan has decided to involve the Toshiba, the manufacturer of the entire structure, emergency management, in order to take "decisive action" to avert the worst. Problems and the need for emergency cooling for the reactor at the center of Onagawa, after a controlled fire and the escaping steam.
According to experts, the sea water cooling system may eventually lead to the corrosion of structures and their early dismantling. The nightmare of the merger. The expert: "Tokyo is not telling the truth." According to the French nuclear agency, the radioactive emissions from a reactor would be much larger than declared by the Japanese authorities.
The value of radioactive emissions may be 1 millisievert per hour (mSv / h), while the index of natural radioactivity is measured around the 0.0001 mSv / h. But the French nuclear agency is not the only voice and data other than official measures. Masashi Goto is a former designer of nuclear facilities, and during a press conference later taken up by the BBC, accused the Japanese government of not telling the whole truth on the situation of atomic plants damaged by the earthquake.
According to Goto, the Japanese "promises a serious crisis": one of the reactors of the Fukushima-Daiichi is "highly unstable". And above all, that the consequences of a possible merger would be "tremendous." So far the Japanese government has said that any merger would not lead to the release of significant amounts of radioactive material.
But Goto responds with a technical analysis: "The Fukushima-Daiichi reactors are subjected to pressure increases beyond expected levels when they were built," he says. According to the designer, there would be "a serious risk of an explosion with radioactive material shot over a large area, well beyond the size of the evacuation of twenty kilometers from the tax authorities." The nuclear expert has accused the government of deliberately hiding vital information: "Not enough has been said about how the hydrogen was vented.
Goto also described as "highly unusual and dangerous" use of sea water to cool the reactor in Fukushima-Daiichi. A radioactive volcano. " Goto describes the worst case scenario, the fusion of the nucleus. That could occur in case of fall of the bars, and their mixing with water. The reaction would be an explosion of solid material, the expert describes as "a volcano that spreads radioactive material." An issue that poisonous could be enhanced and spread by a steam explosion or hydrogen can spread the waste over 50 kilometers.
"A very wide fallout, which could add to the action of the winds, even to the Pacific. Goto concludes fearing the risk of a chain reaction, in a terrible scene, "It is likely to be multiplied: there are many reactors in the area. There could be many Chernobyl." The IAEA: Oganawa is ok. "The radioactivity is back to normal levels in the nuclear Oganawa" writes the International Atomic Energy Agency citing revelations from the Japanese authorities.
Fear also in the U.S.. Worries in the U.S. nuclear power plant in San Onofre, conceived decades ago and built in the early 80's near a fault line in California. And 'one of two nuclear power plants in California, the area with greater seismic risk of the USA. In the United States are 104 plants, 23 of which the design is similar to Japan's Fukushima.
The San Onofre plant is designed to withstand earthquakes of a magnitude 7 on the Richter scale, the Japanese reached magnitude 9. Located not far from the sea, halfway between Los Angeles and San Diego, and supplies electricity to about 1.4 million people in Southern California.

Very interesting article, actually you are the only one in the media that talks about San Onofre Power Plant, am I the only one that clearly see a very close similarity with the danger of what just happened? We just had a tsunami alert and people never say anything about the safety of this old Power Plant....
