Water level at one of the nuclear power plants in the Ishikawa Prefecture in the west of Japan rose higher than the norm after a powerful earthquake that occurred in the region.
According to the Japanese media organization NHK, after the earthquake, Hokuriku Electric Company began to regularly check the water level at nuclear power plants.
Studies have shown that the water level at the power plant rose 3 meters above the norm.
In addition, the damage received the pipes of transformers that supplied the reactors with external electricity. The gap also led to the oil leak. Work to eliminate damage continues.
