International Assessments Ensure Safety of Fukushima’s Treated Radioactive Water
International Assessments Ensure Safety of Fukushima's Treated Radioactive Water
Following the 2011 Fukushima disaster, both Japan and the International Atomic Energy Agency (IAEA) have been working tirelessly to ensure the safety of treated radioactive water from the Fukushima Daiichi Nuclear Power Plant. In this article, we will explore the safety assurances provided by both entities and the extensive reviews conducted by IAEA to ensure public trust in the ongoing operations.
The Role of the IAEA
The IAEA, an international organization established within the framework of the United Nations, plays a crucial role in developing and applying international safety standards in the field of nuclear energy. The organization's efforts in reviewing the safety of ALPS (Advanced Liquid Processing Systems) treated water are particularly significant. Through its comprehensive assessments, the IAEA has provided key reassurances regarding the handling and discharge of treated water into the ocean.
Comprehensive Reviews and Reports
The IAEA has released several reports summarizing its findings from various technical reviews, ensuring transparency and understanding among the international community. Below are brief overviews of the specific topics covered in these reports:
First Report (April 29, 2022)
This report details the review conducted in February 2022 for METI and TEPCO. It covers eight different technical areas, including the properties of the ALPS treated water, the safety of the system and process for ocean discharge, and a radiation environmental impact assessment.
Second Report (June 16, 2022)
The second report focuses on the review conducted in March 2022 by the Nuclear Regulatory Commission (NRC). It covers five technical areas, including government responsibilities and roles, key concepts and safety objectives, and the licensing process.
Third Report (December 29, 2022)
The third report outlines the IAEA's action plan for monitoring radioactive materials in the ALPS process water, environmental monitoring, and analysis, and corroboration of data on occupational exposure of workers at TEPCOs Fukushima Daiichi Nuclear Power Plant.
Fourth Report (April 5, 2023)
The fourth report summarises the safety review conducted in November 2022 for the Ministry of Economy, Trade and Industry (METI) and TEPCO. It covers the same eight technical areas as the first report.
Fifth Report (May 4, 2023)
The fifth report details the review conducted in January 2023 by the Nuclear Regulation Authority. It covers five technical issues, including government responsibilities and roles, key concepts and safety objectives, and the licensing process.
Report on Interlaboratory Comparison of Radionuclide Analyses (May 31, 2023)
This report summarises the results of the interlaboratory comparison (ILC) of radionuclide measurements in ALPS process water, conducted under the review of the IAEA. Intensive comparisons between laboratories help ensure the accuracy of the measurements and their reliability.
Conclusion
The comprehensive reviews and reports released by the IAEA have provided significant reassurance regarding the safety of the treated radioactive water from Fukushima. By adhering to relevant international safety standards, Japan has taken a proactive approach to address public concerns and maintain transparency. The joint efforts of Japan and IAEA are crucial in fostering international understanding and trust in the safety of these operations.
