処理水放出、来年２月下旬に　今年度４回目―東京電力

　東京電力は２１日、東電福島第１原発にたまる放射性物質トリチウムを含む処理水について、４回目の海洋放出を来年２月下旬から開始すると発表した。今年度最後の放出で、これまでの３回と同様、約７８００トンを海水で薄めた上で、海底トンネルを通じて沖合約１キロから流す。（2023/12/21-20:11）

Tokyo Electric Power Company Holdings Inc. said Thursday it will start in late February the fourth round of releasing treated water into the sea from its crippled Fukushima No. 1 nuclear power plant in northeastern Japan.
   As in the previous three rounds, TEPCO will release about 7,800 tons of tritium-containing treated water from a point about 1 kilometer off the coast via an undersea tunnel after diluting the treated water with seawater.
   TEPCO also plans to release 7,800 tons of treated water each in the fifth and sixth rounds, which are expected as early as April. The company will announce its water release schedule for the next fiscal year by March.
   Since August this year, TEPCO has discharged a total of 23,400 tons of the treated water into the sea. Tests of seawater and fishery products by the company and others have found tritium levels far below the state-set safety standards.
