The condenser,
and high-voltage switching station construction are finished.
The construction of the 500,000V high-voltage power lines
was continued in parallel with the plant construction.
The helicopter that is used in the construction of the aerial wires in the mountainous areas.
The electricity generated at this plant is sent (to the prefecture?) via the Shin-Fukushima substation,
and also used internally via the TEPCO switching station.
The uranium fuel used at the nuclear power plant is sintered like chinaware.
Then it is inserted into a special metallic tube that is resistant to corrosion and high temperature.
The object that bundles these rods together is called a "fuel assembly."
This is a fuel inspection.
The workers thoroughly examine the fuel assemblies one by one.
And now, the time to insert the fuel into the reactor has come.
The workers carefully insert the fuel assemblies one by one into the water filled reactor.
Inside reactor #1 are 400 fuel assemblies in total.
The control rods are cautiously removed.
The state of the resulting uranium chain reaction neither increasing or decreasing is called a "reactor criticality."
The reactor gradually approaches criticality.
The engineers closely watching this process, probably also worry about constructions hardships afterwords (???)
Finally, the reactor achieves criticality.
And (arriving at this nuclear day called "the third day"?), Japan headed for the dawn of a new energy.
And now, about 70 atm of 280C steam is sent to the turbine generator.
Full output, 460,000 kw, approaches bit by bit.
Finally, it has arrived.
March 1971, Fukushima #1 Nuclear Power Plant reactor 1's commercial operation has begun.
The construction of Fukushima #1 Nuclear Power Plant gradually continued,
and reactors 1 - 4 were built in Okuma, and reactors 5 and 6 in Futaba
for a total output of 4,700,000 kw, making it the largest nuclear power plant in our nation.
To dispose of the radioactive waste that comes from the plant, a central processing facility is being built.
This facility is capable of properly disposing of various types of liquids and solids.
The vinyl sheets, old rags and materials used in the restricted areas are (?) and packed into drums.
The (?) solid materials are cut and bagged to burn more easily and sent to an incinerator.
Thanks to the incineration process, the volume is reduced to 1/4 of the original amount in the drum.
The waste is placed in drums again and safeguarded in a storage facility.
The radioactive gas produced by incineration is removed by a ceramic filter.
There are 92 ceramic filters in one vessel.
The clothing worn by people who enter a restricted area like the reactor room
is washed at the laundry center (whenever it is worn a lot?)
(???????)
This is a machine that checks the level of radiation in the washed clothing.
The clothing at a safe level is sent to an automatic folding machine.
This is a machine that dries and concentrates liquids other than the laundry water.
The resulting dried concentrate powder is pressure molded into pellets.
The pellets, as compared to traditional disposal methods, are reduced to 1/8 of the usual size
and safeguarded in a nearby storage facility.
At the nuclear power plant, an extremely strict radiation control system is implemented.
When you enter a restricted area, you must always change into approved underwear, jacket and socks,
and pass this checkpoint.
You receive an alarm meter and thermoluminescent dosimeter from the guard here.
A set warning point, for example 30 millirem, is written on the alarm.
Above that point, it is designed to sound an alarm to protect against overexposure to radiation.
During entry, you insert your entry permit and thermoluminescent dosimeter and register.
The various suits are each designed with a specific area or type of equipment in mind.
The reactor building's atmosphere is always maintained at lower than normal pressure,
and is equipped with a double door entrance.
The double doors are an airlock system where either door only opens if the other is closed.
When finishing work and leaving, you must first pass through this exit machine, which examines you carefully.
Then, you must further confirm and log your radiation exposure with your (atmospheric?) monitor, and exit.
Each person must enter their time of entry, and initial radiation, and every month a tally and comparison is performed.
By the way, the Earth we live on also has natural levels of radiation.
The amount of radiation at a nuclear plant is strictly controlled,
so it is very minute compared to natural radiation and causes almost no complications.
Radiation monitoring equipment is set up at various places inside and around the plant,
and the data is sent to the central operations room little by little.
In the local Fukushima prefecture, the nuclear energy center measures radiation levels in the plant vicinity as well.
The cities of Fukushima are steadily continuing to flourish, maintaining a balance with the stable operation of the plant.
The cheerful and hardy children being raised.
Places where locals can gather, like martial arts or sports centers have been built.
Again today, families and students are (?) in the sports centers.
Made on land and facing the sea, Fukushima #1 Nuclear Power Plant, our country's (?) seaside reactor
is a model of innovative engineering in the field of nuclear energy.
The new energy, nuclear, that is born here will be a great energy that supports all of our lives.
