Japan’s Tragedy ? Tohoku Earthquake and Fukushima Nuclear Plants
Japanese are not informed of the truth

Takeichi Saito
Representative, Iwanai Nuclear Plant Study Group
Hokkaido, Japan


The ten nuclear power reactors of the Fukushima Daiichi Nuclear 
Plant are falling into serious problems after one another.  We 
Japanese are not informed why such accidents are happening. 
Neither are we informed of the real tragedy to come.  Even now 
the power company, the government, experts on nuclear power 
energy and the media are hiding the truth from the Japanese 
people, continuing deceiving us.

1.      Weakness of Fukushima Daiichi Nuclear Plant

There are two types of nuclear reactors, the pressure type (PWR) 
and boiling type (BWR), and the Fukushima Daiichi nuclear 
reactors are the latter.  There are two weaknesses in the BWR. 
One is that the control rods, which should function as a break, 
are inserted from the bottom.  Control rods are in the shape of a 
bamboo spear, and hang under a pressure vessel.  They are pushed 
up by water pressure, but this is difficult during an earthquake 
when the control rods are shaking.  In Fukushima during the 
recent earthquake, the rods were ‘fortunately’ inserted and the 
nuclear reactor stopped. The Japanese people were not informed of 
this fact.  The second weakness of BWR lies in its circulation 
pump, which circulates the water inside a pressure vessel.  In 
the BWR structure, the circulation pump is hanging outside the 
pressure vessel.  For this reason BWR is extremely vulnerable to 
vibration caused by an earthquake. A circulation pump has the 
important function of cooling down the nuclear fuel rods.  The 
reason they failed to cool down the nuclear fuel rods in 
Fukushima lies in this structural weakness of the circulation 
pump. We Japanese people were not informed of this fact.

2.      Emergency generator taken away by Tsunami

In a normal situation, nuclear reactors are run by power 
generated by the nuclear power plant itself.  When a nuclear 
power plant stops at the time of an earthquake, this internal 
power runs out first.  When the internal power is exhausted, 
power is supposed to be supplied through power cables connected 
to external power sources. However, due to the earthquake this 
failed.  In the case of a such a failure,  an emergency diesel 
generator is supposed to be switched on.  But the huge Tsunami 
had taken away the building where the generator was stored. 
Tokyo Electric Power Co. hid this important fact simply because 
the generator did not function.  The battery ran out shortly, 
halting power, and thus the Fukushima Daiichi Nuclear Power Plant 
stopped functioning, leading to a total power failure.  A similar 
serious incident of a power failure had already happened on the 
17 June in 2010 in Fukushima Daiichi reactor No.2.  They left it 
as it was without taking any measures.

3.      Why massive leakage of radioactive substance?

We are not informed of what kinds of fuel are used in nuclear 
plants.  One of the fuels used is Uranium fuel and today a high 
4.8% concentration level of Uranium is used.  It is called high 
reaction fuel.  When you burn the high reaction fuel, the level 
of radioactivity of radioactive fallout increases.   Furthermore, 
spent high reaction fuel produces more decay heat than low bun up 
fuel.  Fukushima Daiichi No.3 nuclear reactor uses high reaction 
fuel of Uranium together with Plutonium fuel.  Plutonium burns 
harder than Uranium and, therefore, the level of radioactivity of 
radioactive fallout is high, and so is the temperature of decay 
heat from spent fuel.  Massive radioactive substance was emitted 
when the reactor containment exploded, and hydrogen was produced 
because the used fuel contained a high quantity of radioactive 
fallout.  A high level of 400 mSv was measured around the 
Fukushima Daiichi reactor No.3, because high reaction Uranium 
fuel and Plutonium were used.  Japanese people were not informed 
of this fact.  The devastating risk of the radioactive fallout 
was hidden.

4.      Spent nuclear fuel exploded

Hydrogen was produced from the spent nuclear fuel stored in a 
pool at the Fukushima Daiichi reactor No.4, and three of them 
exploded.  Why it did explode? Another truth was hidden about 
this explosion.  Nuclear plants produced massive amounts of 
radioactive fallout.  In Japan storage of such spent nuclear fuel 
has become a big problem.  Due to the absence of storage 
facilities, when the earthquake happened, the pools were packed 
with radioactive fallout.  Thus the amount of decay heat released 
from spent nuclear fuel was much higher.  Because of the power 
failure, it was no longer possible to circulate the water in the 
pool.  As a result,  the water in the pool gradually evaporated, 
spent nuclear fuel was exposed above water level, and hydrogen 
was produced from the decay heat and exploded.  In other words 
radioactive fallout was packed in the pool beyond its storage 
capacity, and this led to a greater damage.  They hid information 
of this fact from Japanese people.

5.      The difference between internal and external exposure

Hydrogen explosions happened several times, and radioactive 
fallout is falling in Fukushima region, which is gradually 
reaching Tokyo.   But experts on nuclear power, the government 
and the media are repeating that there is no risk to human 
health.  In their explanation they continue deceiving the people 
by stressing that the level of radioactivity released in the air 
is much lower than the exposure received from  X-rays.  Exposure 
from outside, such as from x-rays, is called external exposure. 
What is a greater concern for health is internal exposure, 
because in internal exposure we inhale radioactive substances and 
are exposed inside the body.  Both the government and experts are 
deliberately treating internal and external exposures are the 
same, deceiving Japanese people by saying that there is no harm 
to human health.

6.      The risk of internal exposure
External exposure is a momentary exposure.  If the amount of 
radioactivity is high, the risk of cancer gets higher.  On the 
other hand in case of internal exposure the radioactive substance 
is gradually accumulated in the body over a long period of time. 
In this process immune cells are destroyed and genetic cells are 
harmed.  Therefore, even a small quantity of radioactivity can 
affect health.  In case of internal exposure cancer develops 10 
or 20 years after exposure.  What is scary with internal exposure 
is that if we inhale tiny dust which is invisible, the risk of 
developing cancer grows without us knowing about it.  The 
government, experts and the media have not informed the people of 
this risk.

>From Japan’s tragedy to the global tragedy

Many people are exposed to radioactive substances without knowing 
it.  Children are at higher risk.  The genetic damage to children 
affected by internal exposure will harm their health 10 or 20 
years later.  Our tragedy has just started.  It has started but 
people in Japan have not been informed of these potential risks. 
Japanese people are not able to save their own people.  Many 
people in Japan are appealing to the government on the tragedy. 
But the government does not tell us the truth.  The tragedy of 
Fukushima Daiichi Nuclear Power Plant is already developing to a 
global disaster.  I am appealing to the people in the world.  I 
sincerely appeal to the world that all the nuclear power plants 
should be closed down.

 Takeichi Saito was born in 1953 in Iwanai, Hokkaido, Japan. He 
is the representative of “Iwanai Nuclear Power Plant Study 
 Group”.  He has been measuring the temperature of sea water 
near the Tomari Nuclear Power Plant in Iwanai every day in order 
to study the impact of the Tomari Nuclear Power Plant on the sea. 
On the 28 March 2011, we will celebrate the 33th anniversary of 
his activity on water measurement. He is a self learnt barefoot 
scientist who published articles and books on nuclear power 
plant, its impact on the nature and people’s lives.  He is 
trained and has worked as a nursery teacher.  Today he runs a 
small private tutoring school in Iwanai.

concerned over the devastating situation in the areas recently 
hit by the earthquake in Japan).
