Fukushima Fuel Pool Crisis – “An Issue of Human Survival.”
GlobalResearch
We are now within two months of what may be humankind’s most
dangerous moment since the Cuban Missile Crisis.
There is no excuse for not acting. All the resources our
species can muster must be focussed on the fuel pool at Fukushima Unit 4.
Fukushima’s owner, Tokyo Electric (Tepco), says that within
as few as 60 days it may begin trying to remove more than 1300 spent fuel rods
from a badly damaged pool perched 100 feet in the air. The pool rests on a
badly damaged building that is tilting, sinking and could easily come down in
the next earthquake, if not on its own.
Some 400 tons of fuel in that pool could spew out more than
15,000 times as much radiation as was released at Hiroshima.
The one thing certain about this crisis is that Tepco does
not have the scientific, engineering or financial resources to handle it. Nor
does the Japanese government. The situation demands a coordinated worldwide
effort of the best scientists and engineers our species can muster.
Why is this so serious?
We already know that thousands of tons of heavily
contaminated water are pouring through the Fukushima site, carrying a devil’s
brew of long-lived poisonous isotopes into the Pacific. Tuna irradiated with
fallout traceable to Fukushima have already been caught off the coast of
California. We can expect far worse.
Tepco continues to pour more water onto the proximate site
of three melted reactor cores it must somehow keep cool.Steam plumes indicate
fission may still be going on somewhere underground. But nobody knows exactly
where those cores actually are.
Much of that irradiated water now sits in roughly a thousand
huge but fragile tanks that have been quickly assembled and strewn around the
site. Many are already leaking. All could shatter in the next earthquake,
releasing thousands of tons of permanent poisons into the Pacific.
The water flowing through the site is also undermining the
remnant structures at Fukushima, including the one supporting the fuel pool at
Unit Four.
More than 6,000 fuel assemblies now sit in a common pool
just 50 meters from Unit Four. Some contain plutonium. The pool has no
containment over it. It’s vulnerable to loss of coolant, the collapse of a
nearby building, another earthquake, another tsunami and more.
Overall, more than 11,000 fuel assemblies are scattered
around the Fukushima site. According to long-time expert and former Department
of Energy official Robert Alvarez, there is more than 85 times as much lethal
cesium on site as was released at Chernobyl.
Radioactive hot spots continue to be found around Japan.
There are indications of heightened rates of thyroid damage among local
children.
The immediate bottom line is that those fuel rods must
somehow come safely out of the Unit Four fuel pool as soon as possible.
Just prior to the 3/11/11 earthquake and tsunami that
shattered the Fukushima site, the core of Unit Four was removed for routine
maintenance and refueling. Like some two dozen reactors in the US and too many
more around the world, the General Electric-designed pool into which that core
now sits is 100 feet in the air.
Spent fuel must somehow be kept under water. It’s clad in
zirconium alloy which will spontaneously ignite when exposed to air. Long used
in flash bulbs for cameras, zirconium burns with an extremely bright hot flame.
Each uncovered rod
emits enough radiation to kill someone standing nearby in a matter of minutes.
A conflagration could force all personnel to flee the site and render
electronic machinery unworkable.
According to Arnie Gundersen, a nuclear engineer with forty
years in an industry for which he once manufactured fuel rods, the ones in the
Unit 4 core are bent, damaged and embrittled to the point of crumbling. Cameras
have shown troubling quantities of debris in the fuel pool, which itself is
damaged.
The engineering and scientific barriers to emptying the Unit
Four fuel pool are unique and daunting, says Gundersen. But it must be done to
100% perfection.
Should the attempt fail, the rods could be exposed to air
and catch fire, releasing horrific quantities of radiation into the atmosphere.
The pool could come crashing to the ground, dumping the rods together into a
pile that could fission and possibly explode. The resulting radioactive cloud would
threaten the health and safety of all us.
Chernobyl’s first 1986 fallout reached California within ten
days. Fukushima’s in 2011 arrived in less than a week. A new fuel fire at Unit
4 would pour out a continuous stream of lethal radioactive poisons for
centuries.
Former Ambassador Mitsuhei Murata says full-scale releases
from Fukushima “would destroy the world environment and our civilization. This
is not rocket science, nor does it connect to the pugilistic debate over
nuclear power plants. This is an issue of human survival.”
Neither Tokyo Electric nor the government of Japan can go
this alone. There is no excuse for deploying anything less than a coordinated
team of the planet’s best scientists and engineers.
We have two months or less to act.
For now, we are petitioning the United Nations and President
Obama to mobilize the global scientific and engineering community to take
charge at Fukushima and the job of moving these fuel rods to safety.

If you have a better idea, please follow it. But do
something and do it now.
