原発処理水で魚飼育　来夏から、海洋放出の安全証明へ―東電

　東京電力は２９日、福島第１原発から出る放射性物質トリチウムを含む処理水を海水で薄めたプールで魚介類を飼育する試験を２０２２年夏から実施すると発表した。２３年春ごろの海洋放出に向け、風評被害を抑えるために安全性を証明するのが目的。
　試験では、放出の基準となる１リットル当たり１５００ベクレル程度まで処理水を薄め、ヒラメなどを飼育。海水で育てた魚介類と比較し、放射性物質の濃度や生存率などを公表する。
　試験は漁業関係者や専門家の意見を踏まえて行い、放出開始後も飼育を継続するという。（2021/07/29-21:00）

Tokyo Electric Power Company Holding Inc. plans to launch a test in summer next year to raise fish in treated radioactive water from its stricken Fukushima No. 1 nuclear power plant.
   The test is aimed at easing safety concerns and preventing reputational damage from the planned release of treated radioactive water into the ocean around spring 2023 at the earliest, the company said Thursday.
   In the test, TEPCO will dilute treated water, which includes tritium, with seawater, to reduce the levels of contained radioactive materials to some 1,500 becquerels per liter, a target set by the company for the planned ocean release, and raise flatfish, other fish as well as shellfish and compare them with those raised in seawater.
   The company will release levels of radioactive materials contained in the fish and shellfish and their survival rates.
   The test will be carried out in line with opinions from fishery industry officials and experts.
