Fukushima nuclear nightmare in the core is likely the merger

FUKUSHIMA - The sudden explosion. A roar that shakes ten kilometers of territory. The objectives of the tv cameras, placed for days in the hills, shaking the coast. The pictures are blurry but the scene you see with the naked eye. A huge cloud of yellow and red frame surrounds the white iron and concrete.

We look petrified. A voice muffled cries: "You broke the plant". Moments of panic. A few minutes here and another roar, louder and deeper. The cloud is now a dust cloud that soars into the sky. Skip the cover of the reactor 3 of the central Fukushima 1, Daiichi. It is the monster that thirty men, real heroes of this apocalypse, trying to quell three days.

A race against time. But the nightmare seems endless: at eight in the morning, when Italy was already night, an explosion shook Fukushima. And the government has to admit: "He sold the reactor 2. We can not exclude the risk of escape radiottive. Men against machines. Three reactors that produce energy at temperatures impossible and technical teams which pump sea water to stop the heat: we fight to prevent the fuel to heat and melt irreversibly in the shirts of graphite that surround it.

But it is impossible. The water becomes steam and the protective outer dome is transformed into a pressure cooker. Skip the cap, the fine rain of nuclear radiation is dispersed into the air. Six guards and a technician are cleared away. Ten other specialists to work in Fukushima 2, are injured.

Are infected, one is a boy of 23 years. They spend three hours, a new alarm. Now is the reactor 2, which remained silent until now, that mumbles. The pumps that suck water from the sea go haywire. The warming process reaches the critical limit. The tanks that house the bars are nearly empty mox.

There are only 30 cm of water. The fuel is burning. The shirts of the coating is dissolved, the tablets of radioactive isotopes fall and roam free in the cylinder of steel that protects the core. Then the blast. There is a risk of a merger. Happens inside the ball of red-hot steel. "For a short time," says the spokesman of the Prefecture of Fukushima.

"Only in part, are quick to point out the technicians of Tokyo Electronic Power (TEPCO), operators of the two plants. But something terrible has happened. Two Japanese engineers Atomic Energy Agency appear before reporters. Rather than speak, stutter. They shocked expression. They are hit by a barrage of questions everyone is asking what happened, because there was an explosion.

The explanations are vague, many are convinced that hide something: something terrible, unspeakable. It's the network, once again, to provide glimpses of truth. I blog and tweet collect rumors and speculation. The U.S. aircraft carrier "Ronald Reagan" came to help in rescue operations, suddenly leaves the east coast of the country.

The crew, they know, has the radiation after passing through a cloud in the middle of the Pacific in a day have absorbed the same amount a year. Then there is the escape of the French people called home, the alarm for new acid rain, the traces of iodine in the atmosphere close to central.

It turns out that now, to protect the core, there is only one steel structure. Must be cooled in a stable and continuous. Just too hot and steam will come back to press on this diving suit. But if you really miss the end. Fukushima 1, with three reactors, it becomes like Chernobyl. It will take two hours before filling the cooling tanks.

Nature, cruel, mocking, assists. From the outside, makes the rules as a cause of the earthquake triggered the tsunami.È was this wall of water ten meters high to block the alternative cooling system. This is confirmed by authoritative sources of the IAEA, the Vienna agency for nuclear energy.

Finally, a truth, the first logical explanation for a failure that appears inexplicable. Unbelievable. Can not stand the lies of the government. The country sinks, large factories are closing, the stock market collapses, the economy is in distress. But not enough shoveling billions thrown into the furnace of the business.

Japan is full, hurt, upset, afraid, to want clarity. Nobody - at least officially - he could understand what he was knocked out of the seven emergency generators, those that provide the cooling process of the pumps when there is a drop in supply. Agency inspectors have found. "The terrible shock of last Friday," reveal, "interrupted the flow of electricity.

Were brought into the generators and pumps have continued to enter the water with boron, an element that delays the fission core. Seemed to done. Then came the tsunami and destroyed the sheds that housed the generators. Fukushima was a discovery. The water did not reach more than three reactors, the fuel rods began to heat up beyond measure.

" It took 12 hours to develop an alternative system. Rushed to dozens of technicians and specialists. He called all over the world, have offered advice and suggestions. Nothing: Japan thanked but decided to go it alone. Matter of national pride, 60 years living with the atom. But the solution did not come.

The Prime Minister, Naoto Kan, desperate, turned to Toshiba. "Help yourselves." It was lost time and the reactor will not wait, it continues to produce nuclear energy. Finally, last night, pride gives way to Japan and asks for help to the American experts and IAEA. Meanwhile came the explosion on Saturday.

A shock. The loss. There was an absolute need for water. Has anyone looked at the sea: here it is water. He killed ten thousand people, can save millions. He has built a new cooling system. The pumps have begun to suck and the reactor has subsided. But it was not enough. The water is heated, it should be changed, you must enter it with the right amount, neither little nor too much.

A work of precision, an emergency system, impromptu, with no calibration, no can do. This is when the temperature rises again, full steam forms of radiation, secondary press coverage, it explodes and shines with its load. Those clouds that rise above the plants we see are full of iodine 131 and cesium 137.

Traveling with the wind and Japan is a country dominated by the wind. Yesterday went to the east, south today, tomorrow will return to the west. Rain is expected in the next few hours: it will inevitably acid rain and radioactive. If it yields the last shell of the three reactors, Japan will see hell.
