《Making the water of which temperature and of which pressure is high is boiled in the other plumbly》

The pressure vessel and the apparatus on generating steam are stored in the containtment vessel, and the containtment vessel in the Pressured Water Reactor is made of steel of which thickness is a few centimeters or the other made of conctrete which there is thin steel inside it.

As to the former, its outside is covered with a building made of concrete, and as to the latter, the containtment vessel itself functions as the building.

When detecting something unusual in the atomic reactor like a big earthquake, all the control rods are inserted at once so as to prevent an accident from breaking down. Then the chain reaction on the nuclear fissure stops immediately. The emergency stop on the atomic reactor is called scram.

《When burning the nuclear fuel, plutonium and iodine are caused》

When burnig the uranium fuel in the aotmic reactor, the uranium changes into other material by the nuclear fission. As a result various radioactive material appears from the uranim as the starting point like plutonium, cesium, iodine, and strontium.

Radioactive material gives off radiation and changes into other one one after another. We call the phenomenon radioactive decay.

The period when the decay started is different, according to the kinds on the radioactive material.

For example, iodine 131 takes eight days when half of iodine decays and changes into xenon. Thus the number on atom of radioactive material decreases to the half by the radioactive decay, and we call its period half life. Its periods are various, for the one is a...

《Even if the atomic reator stops, cooling down has to be done. Why?》

When the radioactive decay breaks out, the heat always occurs. We call it the decay heat.

As to the disaster in atomic power plant in Fukushima prefecture, even if the atomic reactor stops, the fuel gives off the heat continuously owning to the decay heat. It's not the nuclear fission.

As to the amounnt of decay heat immediately after the atomic reactor stops, it could have made water no less than 3 ton boil in a second. It's equal to the water in 10 bustub in ordinary house, but it's equal to no more than one seventh of the amount of heat when operating the atomic fuel.

The melting point on the sodium is higher than water, so the heat transfers easily. As a result it's better than water as coolant, moreover it doesn't make the neutron of high speed be slow. The proper is indispensable so as to increase the fuel.

《The earthquake in Tokai area which broke out repeatedly》

What is the earthquake in Tokai area which has been problematic? Though it doesn't break out yet, it's already been named. It's strange, but there is a reason for it. The earthquake in Tokai area looks set to happen in the future. Why? 

The earthquake of which magnitude was 8 used to break out in the location of the center of the earthquake in Tokai area with an interval from a hundred to a hundred and fifty years in the past. It turned out to be clear from the research on a historical archive.

《The earthquake in Tokai area which used to break out repeatedly》 

The earthquake which has been assumed is the boundary earthquake on the plate. The surface on the earth has been covered with the plate. The plate is made of dozens of rock of which shape is the plate, and those rock have moved slowly.

Roughly speaking, half of Japan is on the Eurasia plate, and Philippine plate has sunk under the Eurasia plate from south to northwest some four centimeters a year.

The earthquake breaks out on the boundary between the two plates. It's the earthquake...

It's the earthquake on the boundary of plate.

With the sinking plate, the energy on the earthquake is accumulated, and the energy is released by the earthquake. After that the energy is accumulated... the cycle has been repeated. As a result, the period between the earthquakes is so irregular that its prediction is hard.

It has presumed that the earthquake in Tokai area will break out on the boundary of the Eurasia and Philippine plate, in the area from the Suruga bay to Hamana lake.

《The energy on the earthquake has already been accumulated》

The atomic power plant in Hamaoka is in the center of the areas where the earthquake will break out.

The assumed center of the earthquake on Tokai area has released energy on the scale of magnitude 8 with the interval from a hundred and a hundred and fifty years.

It means that the area has an ability of accumulating the energy in the period from a hundred to a hundred and fifty years.

It was in 1854 when the last earthquake broke out in the Tokai area. 157 years have passed from the last...
