Finally, there is hope that the key factors that lead to the nuclear disaster in Japan's nuclear power plants may be resolved.
Workers working to restore power to the damaged Fukushima reactor have successfully arrived at reactor No. 2 and the operator of the nuclear power plant, Tokyo Electric Power, and said on Friday that they hope to start connecting the wires by Saturday.
But it all depends on whether the pumps and valves that supply the reactor operate properly after a week of explosion, gas and radiation.
Power outage after the earthquake-cum-
Last week's tsunami was responsible for an uncontrolled warming of online reactors and storage tanks storing hazardous spent fuel rods over the past Wednesday.
The analysis that appears now shows that 13 diesel generators have been installed in one of the following places
The bunker near Haitang protects nuclear power plants from Marine attacks.
It is reported that diesel is stored in a tank built in front of the sea to facilitate unloading from the ship.
The reactor shut down automatically after the earthquake. Off-
The field power supply was also snapped up.
When 10-1, the generator managed to provide power for about an hour
The meter-class tsunami reached the nuclear power plant, washed the pond, washed away the diesel oil tank and flooded the generator.
This leads to a critical situation called "station power outage.
Even after closing, the core still has a high amount of waste heat, enough to evaporate 300 tons of water per day.
Therefore, constant pumping is needed to cool the core.
But they need motivation.
That's why a backup generator is needed.
Nuclear design experts are critical of keeping the generator low.
Akio Komori, general manager of Tepco, admitted that the upgrade of the backup generator was a potential investigation problem.
Some nuclear power plants in the United States have the design of the Fukushima nuclear power plant, but they keep the generator at 30-
Concrete walls in centimeters thick
The third backup battery starts after the generator fails.
However, it has the ability to operate the valve in the reactor core isolation cooling, providing only 8 hours of DC power supply (RCIC)system.
According to the US, RCIC does not rely on AC power
The alliance of relevant scientists.
When the battery is exhausted, the reactor and storage pool are effectively burned without cooling water, resulting in heat accumulation, corrosion of fuel rods, generation of hydrogen and its explosion, etc.
Experts say the Fukushima reactor is a marker type I for an "active" cooling system based on electric-powered water flow.
Later, the model had a "passive" cooling system that did not depend on the power.
Questions were also raised about finding the factory on the coast overlooking the earthquake.
A tsunami-prone fault.
