国际原子能机构发布福岛ALPS处理水分析报告：多国实验室结果一致，印证排放影响可忽略的结论
日本外务省11月5日公布，国际原子能机构（IAEA）11月4日发布了福岛第一核电站ALPS处理水排海前分析结果报告。本次分析的样本是经海水稀释后的ALPS处理水，于2025年12月在东京电力公司福岛第一核电站厂区内采集。
参与采样与分析的包括东京电力公司、IAEA官员，以及IAEA选定的来自中国、韩国、俄罗斯和瑞士的第三方实验室专家。这是IAEA框架下「追加措施」的一部分：自2024年10月以来，相关采样已多次进行，其中2025年12月5日进行的是经海水稀释处理水的采集。
IAEA在报告中认定，各参与实验室报告的结果，与IAEA 2023年7月发布的《ALPS处理水安全审查综合报告》一致。该综合报告的结论是，按计划进行的排放对人类和环境的放射性影响可忽略不计。
日本政府表示，将继续与IAEA保持密切协调，以高度透明的方式向国际社会分享信息，促进日本国内外对ALPS处理水排放安全性的理解。
ALPS处理水是经多核素去除设备（ALPS）等处理的水，处理确保除氚以外的放射性物质浓度确实达到安全监管标准；排放入海前还会充分稀释，使包括氚在内的放射性物质浓度远低于监管标准。

IAEA Publishes Fukushima ALPS Treated Water Analysis: Multinational Lab Results Consistent, Reaffirming Negligible-Impact Finding
Japan's Ministry of Foreign Affairs announced on November 5 that the International Atomic Energy Agency (IAEA) published a report on November 4 on the analytical results of ALPS treated water from the Fukushima Daiichi Nuclear Power Station, sampled after dilution with seawater and before discharge into the sea. The samples were collected in December 2025 on the premises of Tokyo Electric Power Company Holdings (TEPCO)'s Fukushima Daiichi plant.
Taking part in the sampling and analysis were TEPCO, IAEA officials and experts from third-party laboratories in China, the Republic of Korea, Russia and Switzerland selected by the IAEA, as part of the additional measures under the IAEA framework. Sampling under those measures has been carried out repeatedly since October 2024, including the December 5, 2025 collection of ALPS treated water diluted with seawater.
In the report, the IAEA concluded that the results reported by the participating laboratories are consistent with the IAEA Comprehensive Report on the Safety Review of the ALPS-Treated Water released in July 2023, which concluded that the discharges as planned would have a negligible radiological impact on people and the environment.
The Government of Japan said it will continue to maintain close coordination with the IAEA in sharing information with the international community in a highly transparent manner and fostering a better understanding of the safety of the discharge of ALPS treated water within both the domestic and international communities.
ALPS treated water is water processed by devices such as the Advanced Liquid Processing System (ALPS) to ensure that the concentration of radioactive materials other than tritium meets the regulatory standards for safety. Before discharge into the sea, it is sufficiently diluted so that radioactive materials, including tritium, are far below the regulatory standards.
