JAPAN - Fukushima Daiichi, the tree that hides the forest

Immediately after the accident, when I learned that the heart of the reactor could begin to melt at any time, I immediately thought of hydrogen explosions would necessarily occur. But nobody has been able to report. It's amazing to see that the specialists were unable to anticipate this, probably for lack of knowledge of the reactor.

"With these words that Takashi Hirose discusses how authorities reacted to the disaster Fukushima Daiichi. Since the accident at Three Mile Island in 1979, survey of nuclear power plants, expressing publicly the problems and hazards of the system. This accident occurred in the United States, radioactive substances were released after the merger of the heart of the reactor, in a radius of 80 kilometers, irradiating the inhabitants.

Operators were still able to prevent hydrogen explosions. "I used to criticize people who are involved in the nuclear, but I admire the computing capacity of Americans who have managed to avoid the explosions. The Japanese have not been able and allowed the explosion to occur. Only now they are trying to connect the reactors to the grid, which should be their priority from the beginning.

Mobilization at the national level was too late. "The government believes that" we have not reached a level immediately injurious to health "about the radioactivity released. However, the levels of radioactivity above the standards were detected in milk in Fukushima Prefecture and in spinach that in Ibaraki.

The rate of radiation received by the technicians working on the site of the plant is very high. "The only thing I wish for now is that the dose of radiation is kept to a minimum. The nuclear disaster has demonstrated that all stations may be in the same situation as that of Fukushima Daiichi.

"Takashi Hirose's concern stems from the fact that Japan can never escape the earthquakes. Driven by this sense of danger induced by inadequate power to earthquakes, he published in August 2010 Jigen Genshiro bakudan [reactors, bombs]. "The shift of the Pacific plate intensifies. It is possible that around the archipelago of large magnitude earthquakes are increasing, "he recalled.

However, in business circles, we hear about giving the impression that the nuclear catastrophe is already forgotten. Questioned by reporters who asked whether the nuclear policy of Japan was at a turning point, Hiromasa Yonekura, president of the Keidanren [the employers' association of Japanese firms], replied in the negative.

"This kind of tsunami occurs once every thousand years. Moreover, it is admirable to note that plants were able to resist this earthquake, "he added. On the need to revise nuclear policy, he was categorical. "There is no question. I think we must be confident, "he said. "He understands nothing, Takashi Hirose indignant.

He talks about once every thousand years when it is due to a tsunami that damage has become so widespread. During the earthquake of Sanriku, which took place there just over a century, in 1896, was recorded at Ryori on the coast of Iwate Prefecture, a wave of 38 meters, and one of Taro 14 meters.

The tsunami of Tohoku [north-eastern Honshu] should never have been the order of the unexpected. Even for me who am not an expert, it was predictable. However, the measures were not taken and this disaster is due to human negligence. "The plant has the greatest risk in the eyes of Takashi Hirose is the Hamaoka, run by Chubu Electric (Chuden) to Omaezaki, in the prefecture of Shizuoka.

"During the earthquake of magnitude 6, which was held in Shizuoka on March 15, my house shook. I was terrified at the thought that this might be the beginning of the great earthquake of Tokai [central part of the Pacific coast of Honshu Island], the big one, very apprehended ". Who says the quake region of Tokai quake told of extreme violence that occurs at regular intervals off Suruga Bay in Shizuoka Prefecture.

The Hamaoka plant is located 5-8 meters above the sea level and is separated from the ocean by a sand dune 10 to 15 meters. "If it is damaged by a tsunami, the consequences will be immediate," recalls Takashi Hirose. Chuden stopped the operation of Units 1 and 2 of the Hamaoka plant, but "I want it also stops the reactors 3, 4 and 5, and that it transfers the fuel rods in a safe place outside the prefecture of Shizuoka.

Consideration should be given a transfer to the Diet at the headquarters of Chubu Electric, in the building of the Ministry of Economy and Industry. It is normal that their undertaking it because, if a problem arose, they would be primarily responsible, "he adds. Takashi Hirose is concerned the argument that "Japan has entered a period of seismic activity" since the great earthquake in Kobe in 1995.

"In 1997, the earthquake Kitaseibu in Kagoshima Prefecture, struck the central Sendai, the 2003 Sanriku Minami earthquake and the 2005 earthquake off Miyagi Prefecture have damaged the Onagawa in 2007 the earthquake off Chuetsu (Niigata Prefecture) caused damage to the Kashiwazaki-Kariwa plant in 2009 and the earthquake in Suruga Bay than Hamaoka.

"Fortunately, we were able to avoid accidents like the one Fukushima, but authorities still have not learned. "A complete power failure affecting even the generators is a predictable situation. However, when we see the current disaster, it is clear that Japan it was totally unprepared. "After this, TEPCO has halted construction of the Central Higashidori (Aomori Prefecture) and Power Development Company has stopped those of the central Oma.

In one of Hamaoka, building a sixth reactor raises more and more protests. What should be the policy when the government and nuclear power companies are racing to expand nuclear complex? Takashi Hirose demands an audit. "It is necessary for us Japanese to take the time to pause to reconsider the issue.

We need to suspend the activity of the 54 reactors of the archipelago. "The fact remains that Japan depends on nuclear power for 30% of its electricity. Because of the accident Fukushima, TEPCO has had to power outages and planned urban life has been disrupted, including the reduction of rail traffic.

Many people are not inclined to tolerate this inconvenience. "In Japan, the information is not transmitted properly. Experts downplay the risks. They probably are trying to avoid panic, but we must first communicate the truth to the public. United States, where there are the same engines as the power plant in Fukushima, the press informs people in a rather alarming.

Which might occur in favor of nuclear power plants after having read this information? "Launches Takashi Hirose. The Tokyo region has lost much of its electricity generation facilities. The summer demand for electricity is increasing, but "with the recession that followed the 2008 financial crisis, demand has declined.

We could increase the production of thermal power plants that do not run at full speed. It could also become aware of waste and ensure the continuous save electricity. "If Japan is moving toward denuclearization, it is likely that the price of commodities, including oil, burns due to an imbalance between supply and demand.

"In the past, it trumpeted that resources would be dry in a few decades, yet there are still some reservations, new deposits are being exploited. We must use this time gained to encourage the use of alternative energy, including renewable energy. It must consider the problem of speculation, but it is hoped that final prices will stabilize according to actual demand.

"Takashi Hirose wants the current tragedy is a first step toward a new turnaround in Japan. "If another accident were to occur due to a plant, the first hit would be our children and our grandchildren. We must reconsider the issue, even if we lose the comfort and quality of life. I hope this time we will draw appropriate lessons.
