処理水タンク満杯、来夏以降に　汚染水減少で遅く―福島第１原発

　東京電力は２７日、福島第１原発で２０２１年度に発生した放射能汚染水量が１日当たり１３０トンと、２０年度の１４０トンより減少したと発表した。これに伴い、汚染水浄化後の処理水を保管するタンクが満杯となる時期を、従来見通しの２３年春ごろから、同年夏～秋ごろと修正した。
　２１年度は平年より降水量が多かったが、東電は損傷した建屋の屋根を補修するなどした結果、汚染水の発生量を減らすことができたとみている。（2022/04/27-21:06）

Tokyo Electric Power Company Holdings Inc. on Wednesday reported a slowdown in the pace of increase in radioactive water at its meltdown-hit Fukushima No. 1 nuclear plant.
   As a result, TEPCO expects to reach the full storage capacity for water treated through water cleanup equipment by around summer or autumn 2023, later than the previously expected period of spring the same year.
   In fiscal 2021 through last month, the daily increase of radioactive water at the northeastern Japan power plant averaged 130 tons, down from 140 tons in fiscal 2020.
   At the plant, rainfall in fiscal 2021 was larger than usual years. But TEPCO said it managed to reduce the amount of contaminated water accumulating at the plant partly by repairing the damaged roof of a reactor building.
   At the plant, radioactive water keeps increasing, because TEPCO uses water to cool damaged reactors while rainwater and groundwater flow into damaged buildings. The company treats the radioactive water to remove most of the radioactive substances.
