今年度初の処理水放出開始　トリチウム量増やす―東電福島第１原発

　東京電力は１０日、福島第１原発にたまる放射性物質トリチウムを含む処理水の海洋放出を開始した。今年度初めてで、通算１２回目。年度内に７回、計約５万４６００トンを放出する計画。
　前年度と同様に約７８００トンを大量の海水で薄め、２８日にかけて海底トンネルを通じて約１キロの沖合に流す。トリチウムの含有量はこれまでより増やす予定。（2025/04/10-14:28）

Tokyo Electric Power Company Holdings Inc. on Thursday began discharging into the ocean treated water from its stricken Fukushima No. 1 nuclear power plant in its first such operation in fiscal 2025.
   It is the 12th round of water discharges that began in August 2023. TEPCO plans to release a total of about 54,600 tons of treated water containing radioactive tritium in seven rounds this fiscal year, which began this month.
   The current round is set to end on April 28.
   As in the previous year, some 7,800 tons of treated water will be released each time after being diluted with large amounts of seawater. The water will be released through an undersea tunnel at a point 1 kilometer off the coast of Fukushima Prefecture, northeast Japan.
   This time, TEPCO plans to increase the amount of tritium contained in the treated water from past discharges.
