In April 2021, Japan announced the Basic Policy on handling of ALPS-treated water stored at the Fukushima Daiichi Nuclear Power Station, which is to discharge ALPS-treated water into the sea surrounding the plant, subject to domestic regulatory approvals. Dialogue between Experts from Japan and China on the Discharge of ALPS Treated Water from TEPCO's Fukushima Daiichi Nuclear Power Station into the Sea 2024/12/13 Visit of IAEA officials and international experts for a review on the discharge of ALPS treated water from TEPCO’s Fukushima Daiichi Nuclear Power Station into the Sea (Results) Jul 4, 2023 · The water stored at the FDNPS has been treated through an Advanced Liquid Processing System (ALPS) to remove almost all radioactivity, aside from tritium. g. A TEPCO illustration shows the flow of treated water. At the site, contaminated water - in part used to cool melted nuclear fuel - is treated by the Advanced Liquid Processing System (ALPS), which removes most of the radioactive contamination, with the exception of tritium.

The sum of the ratios of the concentration of each radionuclide to the regulatory concentration (sum of the ratios to regulatory concentration limit) This is an official page of the Ministry of Economy, Trade and Industry. The current approach outlined in the Basic Policy is to conduct a series of controlled discharges of ALPS-treated water into the sea (‘batch discharges’) over a period of decades. A review report by the International Atomic Energy Agency (IAEA) shows that the plan of discharging diluted ALPS-treated water into the sea is consistent with relevant international safety standards. Apr 2, 2020 · The Subcommittee on Handling ALPS Treated Water (hereinafter referred to the “ALPS Subcommittee”), an advisory committee to the Government of Japan, concluded its report on 10 February 2020 to show available options for disposition of the ALPS treated water and submitted it to the Government of Japan. To ensure the absolute minimum Nov 2, 2023 · Using Agency equipment, the IAEA’s independent on-site analysis confirmed that the tritium concentration in the diluted water that is being discharged is far below the operational limit of 1,500 becquerels per litre. The IAEA confirmed that the tritium concentrations in the previous nine batches, totalling approximately 72 000 cubic meters of water, were also far below Jul 4, 2023 · The Government of Japan announced today that it requested Tokyo Electric Power Company Holdings (TEPCO) to promptly proceed with its preparations for the discharge into the sea of ALPS treated water stored at the Fukushima Daiichi Nuclear Power Station, in accordance with the implementation plan approved by Japan’s Nuclear Regulation Authority. Dec 13, 2024 · The discharge of the ALPS (Advanced Liquid Processing System) treated water from Japan's Fukushima Daiichi Nuclear Power Station (FDNPS) is progressing in line with international safety standards, the Task Force set up by the International Atomic Energy Agency (IAEA) confirmed this week following its latest four-day mission to Japan. Jul 26, 2024 · The ALPS treated water is discharged under strict control, including measuring the concentration of radioactive materials contained in the water before the discharge and confirming that the concentration is below the regulatory standard. Understanding this information will help support reconstruction. The views expressed herein do not necessarily reflect those of IAEA Member States. This treated water is currently stored in about 1000 tanks on site. Legally, ALPS-treated water should be classified as nuclear waste. The event is not related to the discharge of the ALPS treated water. Jan 25, 2024 · 3. This is a report by the IAEA on progress of the IAEA Review of Safety Related Aspects of Handling ALPS-Treated Water at TEPCO’s Fukushima Daiichi Nuclear Power Station. Aug 7, 2024 · The tritium concentration in the eighth batch of diluted ALPS treated water, which the Tokyo Electric Power Company (TEPCO) began discharging today, is far below Japan’s operational limit, International Atomic Energy Agency (IAEA) experts have confirmed. The samples were corroborated based on an interlaboratory comparison (ILC) which involves different laboratories separately testing and analysing samples and then comparing results and procedures to Confirm tritium activity concentration in ALPS treated water. - TEPCO has carried out a radiological environmental impact assessment in line with relevant international safety standards (while also taking the food chain and bioconcentration into consideration). ALPS treated water: Treated water to be re-purified: Sum of ratios of legally required concentrations is less than 1 (Estimate by 7 nuclides in water sampled from outlet) Sum of ratios of legally required concentrations is 1 or higher (Estimate by 7 nuclides in water sampled from outlet) Repurposed tanks (1) Discharge Facility of ALPS Treated Water into the Sea [5] Structure and strength of equipment, protection against natural phenomena such as earthquakes and tsunamis, prevention of misoperation, reliability, etc. Status of work for the 4th discharge of ALPS treated water 3. pomodkgq lvsj htwse yesdvr txrpn rhh vtgyuf yyhjni mtlhtj jbh
