the second phase of the release of water from the damaged Japanese power plant has begun

The second phase of the discharge into the sea of ​​treated water from the damaged Japanese power plant at Fukushima began on Thursday, October 5 in the morning, announced its operator Tepco. On August 24, Japan began evacuating water into the Pacific Ocean which was used to cool the cores of the three reactors at the Fukushima Daiichi power plant, which had melted after the 2011 tsunami. this long-term process then scandalized China.

Also coming from groundwater and rain, this water was stored for a long time in huge tanks on the site of the power plant and treated to rid it of its radioactive substances, with the exception of tritium, which is only dangerous. ‘in very high concentrated doses according to experts. This is why Tepco then proceeds to a very large dilution of the tritiated water with sea water, before evacuating it into the ocean, so that its radioactivity level does not exceed the targeted ceiling of 1,500 Bq/L.

Three other operations until the end of March 2024

“As was the case with the first release, we will continue to monitor tritium levels. We will continue to inform the public in a clear and understandable manner, based on scientific evidence”, a Tepco official told the press, a week before this second phase. A total of approximately 7,800 m3 of tritiated water was released during the first phase of 17 days. Tepco has planned three other similar operations until the end of March 2024.
