Completion of 11m tide embankment at Fukushima nuclear power plant Policy to proceed with construction up to 16m in the future September 29, 4:42
TEPCO announced that it has completed the installation of a seawall with a height of 11 meters for tsunami countermeasures at the Fukushima Daiichi Nuclear Power Station.
In the future, we plan to proceed with the construction of a seawall of up to 16 meters based on the new assumptions made by the government in April.
TEPCO is constructing a seawall on the sea side of the Fukushima Daiichi nuclear power plant on September 25, based on the assumption of a huge earthquake that will occur in the "Kuril Trench" off Hokkaido, which was shown three years ago. Announced that the installation was completed in.
This seawall is a concrete wall with a height of 1.7 meters installed over a total length of 600 meters on the raised land on the sea side of Units 1 to 4, and the height from the sea is 11 meters. I will.
On the other hand, based on the new assumptions made by the national study group in April, if a huge earthquake occurs in the "Japan Trench", it is possible that a tsunami that crosses this seawall will hit the Fukushima Daiichi nuclear power plant. Therefore, in September, TEPCO announced that it would build a seawall with a maximum height of 16 meters by 2023.
