东京电力完成福岛第一核电站第25次处理水排海：本轮约7,800吨，累计约19.6万吨
东京电力公司11月13日宣布，福岛第一核电站2026年度第7次、累计第25次多核素处理系统（ALPS）处理水海洋排放已于当天中午过后完成。
本轮排放于10月26日开始，约7,800吨处理水经大量海水稀释后，通过海底隧道排入电站外约1公里的海域。本轮排出的处理水所含放射性氚总量约为1.4万亿贝克勒尔。排放自2023年8月开始，至第24轮结束时累计排放量为18.84万吨，本轮完成后累计约为19.6万吨。
东京电力2026年度的计划是分8次排放总量约62,400吨处理水，本年度内还将再进行1次。东京电力与日本政府部门的测量称，排放期间及完成后，周边海域海水与水产品的氚浓度均大幅低于日本国家标准，未检出超标。

TEPCO Completes 25th Discharge of Treated Water from Fukushima Daiichi: About 7,800 Tons This Round, Cumulative Total About 196,000 Tons
Tokyo Electric Power Company (TEPCO) announced on November 13 that the seventh discharge of ALPS-treated water in fiscal 2026, and the 25th overall, from the Fukushima Daiichi Nuclear Power Station was completed shortly after noon that day.
The discharge began on October 26. About 7,800 tons of treated water, diluted with large volumes of seawater, were released through an undersea tunnel into the sea about one kilometer off the plant. The treated water discharged in this round contained a total of about 1.4 trillion becquerels of radioactive tritium. Discharges began in August 2023; the cumulative total stood at 188,400 tons through the end of the 24th round and reached about 196,000 tons after this round.
TEPCO plans to discharge a total of about 62,400 tons of treated water in eight rounds in fiscal 2026, with one more round remaining this fiscal year. Measurements by TEPCO and Japanese government agencies found tritium concentrations in seawater and marine products around the plant well below national standards during and after the discharge, with no exceedances detected.
