According to reports, TEPCO plans to divert nuclear sewage through a submarine tunnel to the sea 1 km offshore for discharge, and the ground part of the project has been completed. This is the first submarine operation, marking the substantial progress of sewage preparation.
The report also pointed out that TEPCO plans to officially begin discharging nuclear sewage in the spring of 2023.
On March 11, 2011, a huge earthquake occurred off the coast of Fukushima Prefecture, Japan.
Affected by this, the cores of Units 1 to 3 of the Fukushima Daiichi Nuclear Power Station melted down, and TEPCO continued to inject water into the containment of Units 1 to 3 to cool the cores and recycle sewage.
On April 13, 2021, the Japanese government officially decided to discharge the Fukushima nuclear sewage into the sea after filtering and dilution. The discharge time is expected to last for 20 to 30 years.
