I want to
introduce in my blog an article about Fukushima and nuclear power. It is a
shame for all of us that the most important issue probably for the humanity is
not being covered carefully with full attention and full dedication. It is very
important what is going on in Japan these days. I would never like being a
Japanese today at all. They should be in the streets demanding solutions, efficient
work and also praying for a miracle.
This issue
in particular makes me wonder how bad human specie we are as intelligent being.
After the massive destruction during the
second world war II and the use of nuclear power against human beings. How can
it be such a nuclear race and nuclear proliferation in order to pump the
economies of the nations. How bad are the leaders and how bad we are to
tolerate this scenario. Even now after Chernobyl and Fukushima!! I guess that
there are to many things to fight against and to fight for. We should be more
concern about how our energy comes to our homes, otherwise there will be always
conflicts and problems. Lets see if we have a chance to make the things
better..I can only say that so far so terrible!
This
article I have taken form the website http://www.globalresearch.ca
Fuel Removal From Fukushima’s Reactor 4 Threatens ‘Apocalyptic’ Scenario. Radiation Fuel Rods Matches Fallout of 14,000 Hiroshima Bombs
An operation with potentially “apocalyptic” consequences is expected to begin in a little over two weeks from now – “as early as November 8″ – at Fukushima’s damaged and sinking Reactor 4, when plant operator TEPCO will attempt to remove over 1300 spent fuel rods holding the radiation equivalent of 14,000 Hiroshima bombs from a spent fuel storage tank perched on the reactor’s upper floor.Fukushima Reactor 4

While the Reactor 4 building itself did not suffer a meltdown, it did suffer a hydrogen explosion, is now tipping and sinking and has zero ability to withstand another seismic event.
The Japan Times explained:
To remove the rods, TEPCO has erected a
273-ton mobile crane above the building that will be operated remotely
from a separate room.
[...] spent fuel rods will be pulled from
the racks they are stored in and inserted one by one into a heavy steel
chamber while the assemblies are still under water. Once the chamber is
removed from the pool and lowered to the ground, it will be transported
to another pool in an undamaged building on the site for storage.
Under normal circumstances, such an
operation would take little more than three months, but TEPCO is hoping
to complete the complicated task within fiscal 2014.
Arnie Gundersen, a veteran U.S. nuclear engineer and director of Fairewinds Energy Education, warned this summer that “They are going to have difficulty in removing a significant number of the rods,” and said that “To jump to the conclusion that it is going to work just fine is quite a leap of logic.” Paul Gunter, MD, Director of the Reactor Oversight Project with Takoma Park, Md.-based Beyond Nuclear, also sounded alarm on Thursday, telling Common Dreams in a statement that “Given the uncertainties of the condition and array of the hundreds of tons of nuclear fuel assemblies, it will be a risky round of highly radioactive pickup sticks.” Gundersen offered this analogy of the challenging process of removing the spent fuel rods:
If you think of a nuclear fuel rack as a pack of cigarettes, if you pull a cigarette straight up it will come out — but these racks have been distorted. Now when they go to pull the cigarette straight out, it’s going to likely break and release radioactive cesium and other gases, xenon and krypton, into the air. I suspect come November, December, January we’re going to hear that the building’s been evacuated, they’ve broke a fuel rod, the fuel rod is off-gassing. […]
I suspect we’ll have more airborne releases as they try to pull the fuel out. If they pull too hard, they’ll snap the fuel. I think the racks have been distorted, the fuel has overheated — the pool boiled – and the net effect is that it’s likely some of the fuel will be stuck in there for a long, long time.
The Japan Times adds:
Removing the fuel rods is a task usually assisted by computers that know their exact location down to the nearest millimeter. Working virtually blind in a highly radioactive environment, there is a risk the crane could drop or damage one of the rods — an accident that would heap even more misery onto the Tohoku region.As long-time anti-nuclear activist Harvey Wasserman explained, the
Spent fuel rods must be kept cool at all times. If exposed to air, their zirconium alloy cladding will ignite, the rods will burn and huge quantities of radiation will be emitted. Should the rods touch each other, or should they crumble into a big enough pile, an explosion is possible.“In the worst-case scenario,” RT adds,
the pool could come crashing to the ground, dumping the rods together into a pile that could fission and cause an explosion many times worse than in March 2011.Wasserman says that the plan is so risky it requires a global take-over, an urging Gunter also shared, stating that the “dangerous task should not be left to TEPCO but quickly involve the oversight and management of independent international experts.”
Wasserman told Common Dreams that
The bring-down of the fuel rods from Fukushima Unit 4 may be the most dangerous engineering task ever undertaken. Every indication is that TEPCO is completely incapable of doing it safely, or of reliably informing the global community as to what’s actually happening. There is no reason to believe the Japanese government could do much better. This is a job that should only be undertaken by a dedicated team of the world’s very best scientists and engineers, with access to all the funding that could be needed.As dire as Wasserman’s warning sounds, it is echoed by fallout researcher Christina Consolo, who told RT that the worst case scenario could be “a true apocalypse.” Gunter’s warning was dire as well.
The potential radiation releases in this situation can only be described as apocalyptic. The cesium alone would match the fallout of 14,000 Hiroshima bombs. If the job is botched, radiation releases could force the evacuation of all humans from the site, and could cause electronic equipment to fail. Humankind would be forced to stand helplessly by as billions of curies of deadly radiation pour into the air and the ocean.
“Time is of the essence as we remain concerned that another earthquake could still topple the damaged reactor building and the nuclear waste storage pond up in its attic,” he continued. “This could literally re-ignite the nuclear accident in the open atmosphere and inflame it into hemispheric proportions,” said Gunter.
Wasserman says that given the gravity of the situation, the eyes of the world should be upon Fukushima:
This is a question that transcends being anti-nuclear. The fate of the earth is at stake here and the whole world must be watching every move at that site from now on. With 11,000 fuel rods scattered around the place, as a ceaseless flow of contaminated water poisoning our oceans, our very survival is on the line.
