IAEA Releases ALPS-Treated Water ILC Report
Overview
The Fisheries Agency announced the report published by the IAEA on the 2024 interlaboratory comparison (ILC). The IAEA reported that Japanese laboratories followed appropriate standards for sample collection procedures and demonstrated a high level of capability and reliability. It also said the results were consistent with routine marine monitoring and showed that radionuclide concentrations in the marine environment around 1F were relatively low and stable.
Key points
- The IAEA published the report on the 2024 interlaboratory comparison (ILC).
- The IAEA reported that Japanese laboratories demonstrated a high level of capability and reliability.
- The results indicate that radionuclide concentrations in the marine environment around 1F are relatively low and stable.
Overview
The Fisheries Agency announced the report on the interlaboratory comparison (ILC) supporting marine monitoring related to ALPS-treated water, published by the International Atomic Energy Agency (IAEA). The report summarizes the results of the third ILC conducted by the IAEA in 2024.
The ILC has been conducted since 2022 under the Terms of Reference (TOR) for the safety review of the handling of ALPS-treated water, signed with the IAEA in July 2021.
Impact
The IAEA reported that the ILC results were also consistent with routine marine monitoring in Japan and showed that radionuclide concentrations in the marine environment around 1F remain relatively low and stable.
Details
The Fisheries Agency is responsible for collecting samples of fishery products, among other tasks. The IAEA and the Japanese government jointly collected marine samples around Tokyo Electric Power Company Holdings, Inc.'s Fukushima Daiichi Nuclear Power Station (1F). The IAEA and Japanese laboratories then analyzed them independently, after which the IAEA compared and evaluated the results.
The IAEA found that, for analyses including tritium, Japanese laboratories' sample collection procedures followed appropriate standards needed to collect representative samples. It also reported that the current ILC and accurate analytical results obtained in the past demonstrated a high level of capability and reliability among Japanese laboratories.
Laboratories selected by the IAEA in China, South Korea, and Switzerland also participated in the ILC. The full report is available on the IAEA website.
