2024年1月，日本福岛第一核电站因附近海域发生强烈地震，一度暂停了核污染水的排海作业。此次地震导致部分设备受损，出于安全考虑，东京电力公司（TEPCO）立即中止了排放流程，并对相关设施进行全面检查。经过数周的评估与修复，日本政府与东电于2月初宣布，在确认系统安全无虞后，核污染水排海工作已重新启动。根据日本政府和国际原子能机构（IAEA）的说法，所排放的处理水经过多核素去除系统（ALPS）净化，除氚以外的放射性物质浓度均低于监管标准。氚因其难以从水中分离，将以稀释方式排放，确保其浓度远低于世界卫生组织饮用水标准。尽管如此，该计划仍引发中国、韩国等周边国家及环保组织的持续担忧与反对，质疑长期生态影响及数据透明度。重启排海行动标志着日本持续推进其核废水处置方案的决心，但也凸显了区域间在核安全与环境治理上的信任赤字。未来，国际社会将持续关注排放过程的监测机制、独立核查以及对海洋生态的实际影响。
In January 2024, Japan temporarily halted the discharge of treated radioactive water from the Fukushima Daiichi Nuclear Power Plant into the ocean following a strong earthquake near the facility. The quake caused minor damage to some equipment, prompting Tokyo Electric Power Company (TEPCO) to suspend operations as a precaution and conduct comprehensive safety inspections. After several weeks of assessment and repairs, the Japanese government and TEPCO announced in early February that the discharge had resumed, confirming the system’s safety.According to Japanese authorities and the International Atomic Energy Agency (IAEA), the discharged water has been processed through the Advanced Liquid Processing System (ALPS), which removes most radionuclides except tritium. Tritium, which is difficult to separate from water, is diluted to concentrations well below the World Health Organization’s drinking water standards before release. Nevertheless, the plan continues to draw criticism and concern from neighboring countries like China and South Korea, as well as environmental groups, who question the long-term ecological impact and transparency of data.The resumption of the discharge underscores Japan’s commitment to its wastewater disposal strategy but also highlights a trust gap among regional stakeholders regarding nuclear safety and environmental governance. The international community will continue monitoring the discharge process, independent verification mechanisms, and its actual impact on marine ecosystems.
