原発処理水、沖合１キロ放出案　海底にパイプライン設置―東電・政府

　東京電力福島第１原発から出る放射性物質トリチウムを含んだ処理水をめぐり、東京電力ホールディングス（ＨＤ）と政府が、海底にパイプラインを設置した上で１キロ程度の沖合に放出する案を検討していることが１１日、分かった。原発近くの沿岸から直接排出する方法と沖合放出のいずれを採用するかについて、原子力規制委員会も交えた本格的な協議が来月にも始まる見通し。（2021/05/11-18:36）

Tokyo Electric Power Company Holdings Inc. and the Japanese government are considering a plan to release treated radioactive water from the crippled Fukushima No. 1 nuclear power plant into the sea about 1 kilometer from the coast, informed sources said Tuesday.
   The plan calls for a pipeline to be set up at the bottom of the ocean, according to the sources.
   TEPCO, the government and the Nuclear Regulation Authority are expected to kick off full-fledged talks next month to decide whether to release the water directly from the coast near the power plant or offshore through a pipeline, the sources said.
   The TEPCO plant in Fukushima Prefecture, northeastern Japan, was heavily damaged in the March 2011 earthquake and tsunami. The treated water contains tritium, a radioactive substance.
   Groundwater and rainwater continue to flow into damaged reactor buildings at the nuclear power plant, ending up being contaminated with radioactive substances.
