２回目の処理水放出開始　計７８００トン、年内にも３回目―東電福島第１原発

　東京電力は５日、福島第１原発にたまる処理水について２回目の海洋放出を開始した。８～９月に行った初回と同様、放射性物質トリチウムを含む約７８００トンの処理水を大量の海水で薄め、海底トンネルを通じて沖合約１キロから放出する。
　東電によると、放出に際し、漏えいなどの異常は確認されていないという。２回目の作業は２３日までに終了する見込みで、３回目は設備点検を経て、早ければ年内にも実施するとしている。（2023/10/05-19:29）

Tokyo Electric Power Company Holdings Inc. on Thursday started the second round of the release of treated water from its meltdown-hit Fukushima No. 1 nuclear power plant into the ocean.
   As in the first round, which took place from Aug. 24 to Sept. 11, the operator of the plant in Fukushima Prefecture, northeastern Japan, will dilute some 7,800 tons of the tritium-containing treated water with a large amount of seawater before releasing it at a point 1 kilometer off the coast via an underground tunnel. The second round will run for about 17 days.
   After the end of the first round, TEPCO checked related facilities including pipework and a pump to see if there is any abnormality. The company checked the diluted water on Tuesday and confirmed that the concentration of tritium was below safety standards.
   On Thursday, TEPCO started the water discharge by activating a pump around 10:20 a.m.
   TEPCO checks the tritium concentration in nearby sea areas every day. Also, the Environment Ministry, the Fisheries Agency and the prefectural government of Fukushima conduct their own inspections on seawater and aquatic products. These inspections confirmed that the concentration levels were below the state standards.
