Alert: Fukushima Coverup, 40 Years of Spent Nuclear Rods Blown Sky High
by Paul Joseph Watson and Kurt Nimmo
In addition to under reporting the fires at Fukushima, the Japanese
government has not told the people about the ominous fact that the
nuclear plant site is a hellish repository where a staggering number
of spent fuel rods have accumulated for 40 years.
A contributor to the Occupational and Environmental Medicine list who
once worked on nuclear waste issues provided additional information
about Fukushima’s spent fuel rod assemblies, according to a post on
the FDL website.
“NIRS has a Nov 2010 powerpoint from Tokyo Electric Power Company (in
English) detailing the modes and quantities of spent fuel stored at
the Fukushima Daiichi plant where containment buildings #1 and #3 have
exploded,” he wrote on March 14.
The Powerpoint is entitled Integrity Inspection of Dry Storage Casks
and Spent Fuels at Fukushima Daiichi Nuclear Power Station and can be
read in full here.
The document adds a new and frightening dimension to the unfolding
disaster.
The Fukushima Daiichi plant has seven pools dedicated to spent fuel
rods. These are located at the top of six reactor buildings - or were
until explosions and fires ravaged the plant.
On the ground level there is a common pool in a separate building that
was critically damaged by the tsunami. Each reactor building pool
holds 3,450 fuel rod assemblies and the common pool holds 6,291 fuel
rod assemblies. Each assembly holds sixty-three fuel rods. In short,
the Fukushima Daiichi plant contains over 600,000 spent fuel rods - a
massive amount of radiation that will soon be released into the
atmosphere.
It should be obvious by now that the authorities in Japan are lying
about the effort to contain the situation in order to mollify the
public. It is highly likely there are no workers on the site
attempting to contain the disaster.
Earlier today, a report was issued indicating that over 70% of these
spent fuel rods are now damaged - in other words, they are emitting
radiation or will soon. The disclosure reveals that authorities in
Japan - who have consistently played down the danger and issued
conflicting information - are guilty of criminal behavior and
endangering the lives of countless people.
On Tuesday, it was finally admitted that meltdowns of the No. 1 and
No. 2 reactor cores are responsible for the release of a massive
amount of radiation.
After reporting that a fire at the No. 4 reactor was contained, the
media is reporting this evening that it has resumed. The media
predictably does not bother to point out why the fire is uncontainable
- the fuel rods are no longer submerged in water and are exposed to
the atmosphere and that is why they are burning and cannot be
extinguished.
It cannot be stressed enough that the situation at Fukushima
represents the greatest environmental disaster in the history of
humanity, far more dangerous that Chernobyl, and the government of
that country is responsible.
Perhaps the most underreported and deadliest aspect of the three
explosions and numerous fires to hit the stricken Fukushima nuclear
reactor since Saturday is the fact that highly radioactive spent fuel
rods which are stored outside of the active nuclear rod containment
facility are likely to have been massively compromised by the blasts,
an elevation in the crisis that would represent “Chernobyl on
steroids,” according to nuclear engineer Arnie Gundersen.
As you can see from the NPR graphic below, the spent fuel rods are
stored outside of the active nuclear rod containment casing and close
to the roof of the reactor complex. Video from Saturday’s explosion
and subsequent images clearly indicate that the spent fuel rods at
Fukushima unit number one could easily have been compromised by the
blast.
According to Arnie Gundersen, a nuclear engineer at Fairewinds
Associates and a member of the public oversight panel for the Vermont
Yankee nuclear plant, which is identical to the Fukushima Daiichi unit
1, the failure to maintain pools of water that keep the 20 years worth
of spent fuel rods cool could cause “catastrophic fires” and turn the
crisis into “Chernobyl on steroids.”
The BBC is now reporting that “spent fuel rods in reactors five and
six are also now believed to be heating up,” with a new fire at
reactor 4, where more spent rods are stored, causing smoke to pour
from the facility.
“Japanese news agency Kyodo reports that the storage pool in reactor
four - where the spent fuel rods are kept - may be boiling. Tepco says
readings are showing high levels of radiation in the building, so it
is inaccessible,” adds the report.
“At the 40-year-old Fukushima Daiichi unit 1, where an explosion
Saturday destroyed a building housing the reactor, the spent fuel
pool, in accordance with General Electric’s design, is placed above
the reactor. Tokyo Electric said it was trying to figure out how to
maintain water levels in the pools, indicating that the normal safety
systems there had failed, too. Failure to keep adequate water levels
in a pool would lead to a catastrophic fire, said nuclear experts,
some of whom think that unit 1’s pool may now be outside,” reports the
Washington Post.
The rods must be kept cool because otherwise they start to burn and,
in the case of reactor number 3, would release plutonium and uranium
in the form of vapor into the atmosphere.
“That’s bad news, because plutonium scattered into the atmosphere is
even more dangerous that the combustion products of rods without
plutonium,” writes Kirk James Murphy.
“We’d be lucky if we only had to worry about the spent fuel rods from
a single holding pool.
We’re not that lucky. The Fukushima Daiichi plant has seven pools for
spent fuel rods. Six of these are (or were) located at the top of six
reactor buildings. nulle “common pool” is at ground level in a
separate building. Each “reactor top” pool holds 3450 fuel rod
assemblies. The common pool holds 6291 fuel rod assemblies. [The
common pool has windows on one wall which were almost certainly
destroyed by the tsunami.] Each assembly holds sixty-three fuel rods.
This means the Fukushima Daiichi plant may contain over 600,000 spent
fuel rods.”
There have been massive design issues with the Mark 1 nuclear reactor
stretching back three decades.
As ABC News reports today, “Thirty-five years ago, Dale G. Bridenbaugh
and two of his colleagues at General Electric resigned from their jobs
after becoming increasingly convinced that the nuclear reactor design
they were reviewing — the Mark 1 — was so flawed it could lead to a
devastating accident.”
The problems we identified in 1975 were that, in doing the design of
the containment, they did not take into account the dynamic loads that
could be experienced with a loss of coolant,” Bridenbaugh told ABC
News in an interview. “The impact loads the containment would receive
by this very rapid release of energy could tear the containment apart
and create an uncontrolled release.”
