処理水の３回目放出終了　４回目は年明け以降に―東電

　東京電力は２０日、福島第１原発にたまる処理水の３回目の海洋放出を終了したと発表した。漏えいなど設備のトラブルはなく、放射性物質トリチウムの濃度に異常は確認されなかった。今年度は、あと１回の放出を予定しており、年明け以降の実施を見込んでいる。
　３回目は２日から開始。１、２回目と同様に約７８００トンの処理水を海水で薄め、海底トンネルを通じて放出した。東電は、今年度中に計約３万１２００トンの処理水を計４回に分けて流す計画を立てている。
　放出開始以降、同社は周辺海域で海水のトリチウム濃度を毎日測定。環境省や水産庁なども海水や水産物を調べているが、国の基準を大幅に下回っている。（2023/11/20-18:18）

Tokyo Electric Power Company Holdings Inc. has completed the third round of releasing into the sea tritium-containing treated water from its crippled Fukushima No. 1 nuclear power plant in northeastern Japan.
   In its announcement Monday, the plant operator added that there were no equipment problems, such as leaks, or abnormalities in tritium levels.
   TEPCO plans to conduct another round of such water release before the end of March, which is expected to start after the turn of the year.
   In the third round, which began Nov. 2, the company discharged some 7,800 tons of the treated water, the same amount as in the previous two rounds, through an undersea tunnel after diluting it with seawater.
   TEPCO plans to release a total of some 31,200 tons of the treated water in four rounds in the year through March.
