Some experts questioned its safety.
He pointed out that there may be a active fault beneath Ohi Nuclear Plant.
Bedrock is skewed approximately 50cm long.
It has shifted for long length, which means it has moved in a new era.
What does Nuclear Safety answer this pointed out?
We have determined there is no activity so far.
Nuclear Safety say“That is not the Active Fault”.
Professor Watanabe pointed out that what look like?
This time, it was pointed out that there may be Active Faults under Ohi Nuclear Plant by Professor Mitsuhisa Watanabe of Toyo University.
He was reviewing the material with Professor Yasuhiro Suzuki of Nagoya University.
They investigated Active Faults in grounds of Tsuruga Nuclear Plant and around Shimane Nuclear Plant,
He is experts examining nuclear facilities and Active Faults.
Where and what kind of Active Fault through do Ohi Nuclear Plant ground have?
Regarding Ohi Nuclear reactors No.1,2,3,4,
Fault party F-6 is located between No. 2 and 3 reactors.
F-6 fault located in this site may be the Active Faults.
Professor Watanabe has been pointed out. Fault called F6 of 900 meters length running north-south through the center of Ohi Nuclear Plant.
The evidence that they actively “OK” is a sketch of this side.
South side.
Kansai Electric Power Co. previously determine this fault is not Active Fault, because of bedrock is not shifted.
However, the view of Professor Watanabe is different.
It is the sketch of opposite side. It is north.
This is strange!
Pr. Watanabe confirmed the bedrock of the northern nuclear power plant after inspecting the installation of nuclear power plant license application.
Bedrock is shifted roughly 50cm.
A layer of gravel riding on it is shifted about 50cm.
After the gravel layer has accumulated, looks like F-6 has moved.
Professor Watanabe pointed out, Bedrock and brown layer of gravel piled on is shifted by the same amount.
It might be this fault has moved in a new era. In other words, there is a possibility of Active Faults.
Furthermore, in addition to F-6, there are about 10 small faults beneath the reactor.
It located underneath of Unit 1 Unit 2 Unit 3 Unit 4 all,
in which there is possible of active faults we suspect.
The reactor itself might be made equivalent sturdy. But, if the building break, it will lose all piping.
We are not forced to think that serious damage will occur considerable, if the faults beneath reactors move.
We have been telling them, “There is a risk. So, please properly evaluated it.”
If the reactor confirmed safety can be running again, I think. However, this has not been confirmed.
First of all, they would go to investigate at there. Then, just shows us, it's certainly not the Active Fault.
Regarding Pr.Watanabe pointed out that there may be an active fault under the Ohi Nuclear Plant,
Masashi Goto, reactor designer, familiar with reactor structure,
The building itself may be corrupted when a large force is applied.
If it is not broken, it will lean.
The most worrying is no longer fit the control rod.
If the control rod is not turned on, nuclear reaction does not stop.
Then, it becomes a Chernobyl type meltdown rather than normally,
Causing the explosion!
It has to be called “This is not an active fault.”
Otherwise, as the plant company is not acceptable.
In the national guidelines also determine “Do not build a nuclear reactor just above the active fault moves in an earthquake.”
Regarding Pr. Watanabe’s pointed out,
Kansai Electric Power Co. replied to our coverage.
When the expansion of Units 3 and 4,
our company had also re-evaluation of seismic safety survey in 1982 and 2006,
We have been evaluated that this fault is not running at least period of Active Faults can be concluded.
This result is also confirmed by the Japan government.
How does the Nuclear Safety think regarding the possibility of Active Faults pointed out by Pr. Watanabe?
We visited the importance of off-site center located in Ohi town when responding to emergencies.
What a huge place this is!
Off-site center of the important base corresponding to the nuclear plant emergency, in Ohi town.
There is fault on the grounds of Ohi Nuclear Plant which is a possibility of Active Faults very much.
It tentatively, as a result of screening by Nuclear Safety,
Conclusion is brought out in which is not Active Faults
With regard to it also, well..
Recently, we also reported to the Committee on Nuclear Safety in Fukui Prefecture,
Well.., we received that it is reasonable assessment, we have recognized.
If safety can be ensured ?
Yes it is.
Mr.Koga, ex-bureaucracy of Ministry of Economy, Trade and Industry: If people look at that photo, they feel that is dangerous from the view.
For example,
at the bottom of a steep cliff, there is the power car, the last dependable power car, putting on.
I asked them it because of importance.
It should be OK, because it is calculated by the computer,
They said.
When I said, nobody wants to build the house at such place,
They did silent answer.
Then, I found recently, the place of power car is dangerous, so, it has moved.
They do let's divide them to several places. In other words, they do flip-flop
As seen from the amateur like us, they do in cold blood, that would be dangerous indeed.
After all, it is done by all computer and grammar.
It was okay after the calculation, that’s it.
So, I really cannot trust them all.
Nuclear power safety which has been at the mercy of nuclear power companies with adhesion relationship is still doing it,
If we do not change it, is not hopelessly!
It is a new problem.
It is the Oi nuclear power plant. There are No. 1 and No.2 reactors from the sea, and No. 3, No.4 planning to re-operate.
There is a fault called f6 between these No. 2 and No. 3.
It is F6 fault that is possibility of an active fault.
The type is motion method called Transcurrent fault.
Power is applied like this.
When this power is applied, the ground shifts horizontally which is Transcurrent Fault.
It is concluded the same type as Nojima fault caused Kobe earthquake.
This Nojima fault, at Awaji-shima, the crack went into like this, after the earthquake.
It is shifted about 1 meter horizontally.
The photograph from the bottom. There is a wall.
It could come and was a wall straight at first.
It is shifted greatly about 1 meter.
Most of this immediately near building is flawlessness.
This is the feature of a transcurrent fault about whether damage comes out in the narrow range.
However, conversely saying, if it was right above, possibly serious damage had come out.
I would like to see the Oi nuclear power plant and a fault.
The fault is running completely under No. 1 which also has faults.There is F6 faults right here.
There are faults, underground of No. 3 and No. 4 which are planning re-operate.
This fault may also move if the near "Kumagawa" fault moves, the specialist is asking for re-investigation.
Furthermore, The Tsuruga Nuclear Plant, there is “Urazoko” faults which supposed to not move. But, they have found it Active Fault, now.
So, the faults under beneath of Tsuruga plants are possibly active faults. ** Translation & Subtitle: Jo2Rayden **
