TEPCO, the operator of the Fukushima Daiichi nuclear power station, has begun the second phase of discharging water that has been treated to remove radiation and other contaminants into the ocean. The agency cited Kyodo for the report.
Officials from the plant confirmed, “The second round of purified water discharge has started.” This phase is designed to continue over the coming weeks as part of a broader program to manage accumulated cooling water used for the damaged reactors.
TEPCO’s plan outlines a three-week period for the second phase, with roughly 460 tons of water released daily through an underwater tunnel. In total, more than 1.25 million tons of water have been stored at the site’s reservoirs since it was collected to cool the reactors affected by the 2011 tsunami. The water treatment process aims to reduce the level of radioactive materials to meet regulatory standards before release.
In September, Tokyo officials indicated that additional treated water would be discharged from the Fukushima Daiichi facility by March 2024, continuing a long-term effort under strict monitoring. The plan is part of Japan’s ongoing strategy to handle groundwater and cooling water at the site, while maintaining environmental safeguards and monitoring the marine ecosystem.
Public figures and residents have expressed a range of concerns and opinions. Some have emphasized the importance of transparent data and independent oversight to reassure fishing communities and neighboring nations about seafood safety. Others noted the need for continued scientific assessment and open communication as operations proceed.
In interviews and public statements, observers have underscored that the decision to release treated water is taken within a framework of international guidelines and national regulations, with ongoing verification of radiation levels and environmental impact. The process includes continuous reporting, sampling, and external review to ensure compliance with safety standards and to address any emerging concerns.
Throughout the ongoing discharge program, authorities stress the role of rigorous monitoring, credible reporting, and updates from TEPCO and regulators. They emphasize that the treated water undergoes multiple filtration steps to reduce radioisotopes, and that the discharge is conducted gradually to minimize any potential effects on marine life and coastal communities. The situation remains closely watched by scientists, policymakers, and stakeholders across the region.
