処理水放出、今年度４回目が終了　東電福島第１原発

　東京電力は２５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今年度４回目の海洋放出を終えたと発表した。昨年８月２４日の放出開始以降、通算８回で計約６万２４００トンを海に流した。
　放出では毎回、約７８００トンの処理水を大量の水で薄め、約２週間余りかけて海底トンネルから約１キロ沖合に流している。国や東電が周辺海域のトリチウム濃度などを測定しているが、国の基準値を大幅に下回っている。今年度はあと３回放出する予定。（2024/08/25-14:13）

Tokyo Electric Power Company Holdings Inc. said Sunday that it has completed the fourth round of the fiscal 2024 release of treated water into the ocean from its disaster-crippled Fukushima No. 1 nuclear power plant in northeastern Japan.
   Since the discharge began on Aug. 24 last year, TEPCO has released some 62,400 tons of the treated water, which contains small amounts of radioactive tritium, in a total of eight rounds.
   In each round, about 7,800 tons of treated water was diluted with a large amount of seawater before being discharged offshore, at a point about 1 kilometer from the plant, through an undersea tunnel over a two-week period.
   The Japanese government and TEPCO have been monitoring tritium levels in nearby waters. The levels have been well below the government-set standard.
   TEPCO plans three more rounds of the discharge in the current fiscal year ending in March 2025.
