Released in the morning as scheduled with no problems with weather conditions.
A total of about 7,800 tons were released by the 23rd… Radiation testing is also conducted simultaneously.
On the 5th, the second ocean discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant (Japanese government name treated water) began. A total of about 7,800 tons are scheduled to be released by the 23rd.
According to Jiji News Agency, Fukushima TV, etc., Tokyo Electric Power Company began the second discharge of contaminated water from the Fukushima nuclear power plant as scheduled as there were no problems with weather conditions this morning.
As with the first release conducted in August and September, approximately 7,800 tons of contaminated water containing the radioactive tritium (tritium) will be diluted with a large amount of seawater and released through an undersea tunnel about 1km off the coast of Wojon over a period of 17 days.
Secondary discharge begins with 1 ton of contaminated water, which has confirmed that the tritium concentration is significantly below 1,500 ㏃ per liter (1/40th of the national standard) planned by Tokyo Electric Power Company. After that, 460 tons of contaminated water is diluted with seawater and discharged into the sea every day. This is equivalent to 10 tanks.
Tokyo Electric Power Company continues to monitor tritium concentration even during the second discharge period. Tritium is analyzed in the seawater around the nuclear power plant, and if more than 700 ㏃ per L is detected, the emission is immediately stopped.
Previously, Tokyo Electric Power Company started the first ocean discharge on August 24th and completed it on September 11th. A total of 7788 tons were discharged.
The Japanese government, Tokyo Electric Power Company, and Fukushima Prefecture announced that there were no abnormalities as a result of measuring the concentration of tritium contained in seawater or seafood around the nuclear power plant.
Before conducting the second discharge, Tokyo Electric Power Company measured the tritium concentration by diluting about 1 ton of contaminated water with 1,200 tons of seawater in a large water tank. As a result, the maximum was 87 becquerels (㏃) per L, which was significantly below the emission standard planned by Tokyo Electric Power Company (less than 1,500 ㏃ per L).
Shinsuke Yamanaka, chairman of Japan’s Nuclear Regulatory Commission, asked at a regular press conference on the 4th about Tokyo Electric Power Company’s secondary discharge of treated water into the ocean, “Please proceed with the discharge with caution to avoid any small mistakes.”
