処理水タンク、解体に着手　来年度末までに１２基―東電福島第１原発

　東京電力は１４日、福島第１原発構内にある処理水貯蔵タンクの解体に着手したと発表した。２０２５年度末までに１２基を解体する計画。
　タンクは高さ約１２メートル、容量約７００立方メートル。処理水を海に放出して空になったタンク１２基をまず解体し、隣接する９基も、中に残っている処理途中の水を別のタンクに移した上で、順次解体を進める。
　解体には高所作業車を用い、作業員がガスバーナーで切断し、破片をコンテナに入れて当面の間、構内で保管する。１４日は午前８時ごろから作業を開始。約５時間半かけて１基の上部のふたを取り外し、地上に下ろしたという。（2025/02/14-18:17）

Tokyo Electric Power Company Holdings Inc. said Friday it has started dismantling tanks used to store treated wastewater from its crippled Fukushima No. 1 nuclear power plant.
   By the end of March 2026, the company plans to dismantle 12 tanks that became empty after the stored treated water was released into the ocean, it said.
   Each of the tanks, located at the plant in Fukushima Prefecture, northeastern Japan, is about 12 meters high and has a capacity of around 700 cubic meters. Another nine tanks in an adjacent area will also be dismantled after the water in the treatment process left in them is transferred to other tanks.
   Workers will use gas burners to cut the tanks into pieces. The pieces will be stored for the time being in containers on the premises of the plant, severely damaged by the March 2011 powerful earthquake and tsunami.
   In August 2023, TEPCO began discharging into the sea tritium-containing treated water from the Fukushima No.1 nuclear plant in order to reduce the number of the storage tanks, which stands at about 1,000, and create space for the plant's decommissioning work.
