Tokyo Electric Power Company Holdings Inc. - Considering 'the Basic Policy on handling of ALPS treated water at the Tokyo Electric Power Company Holdings' Fukushima Daiichi Nuclear Power Station' (announced by the Japanese government in April 2021), TEPCO had been reviewing the details of the design and operation of ALPS treated water dilution/discharge facility and related facilities regarding the handling of ALPS treated water at the Fukushima Daiichi Nuclear Power Station, listening to opinions of the people in the region and parties concerned.
On December 21, 2021, TEPCO submitted the 'Application Documents for Approval to Amend the Implementation Plan for Fukushima Daiichi Nuclear Power Station Specified Nuclear Facility' regarding the design of ALPS Treated Water Dilution/Discharge Facilities, etc. to the Nuclear Regulation Authority (NRA), and on July 22, 2022, these application documents were approved by the NRA.
On December 20, 2021, TEPCO also submitted a 'Request for Prior Consent*1' to Fukushima Prefecture, Okuma Town, and Futaba Town regarding the installation of ALPS treated water dilution/discharge facilities, etc. based on the 'Agreement to Ensure Safety in Surrounding Areas Related the Decommissioning of Fukushima Daiichi Nuclear Power Station*2 (hereinafter the Agreement to Ensure Safety in Decommissioning)'. On August 2, 2022, municipalities granted us prior consent after confirming the state of the necessary safety measures.
In installing the ALPS treated water dilution/discharge facilities, etc., TEPCO will steadily implement initiatives based on the Japanese government's basic policy and will respond sincerely to each and every one of the eight requirements regarding additional safety improvements and easy-to-understand information dissemination laid out in the 'Report on the Confirmation Results of the new Installation of ALPS Treated Water Dilution/Discharge Facility and Related Facilities at the TEPCO Fukushima Daiichi Nuclear Power Station' issued by the Fukushima Prefecture Nuclear Power Station Safety Assurance Technical Review Committee.
Continuing to move steadily and safely forward with decommissioning/contaminated water and treated water measures at Fukushima Daiichi Nuclear Power Station requires risk reduction efforts in the long term. We will steadily work to further reduce the amount of contaminated water generated and to properly manage the radioactive waste generated in contaminated water treatment, which the prefectural governor and the mayors of the towns gave us on August 2, 2022.
Furthermore, we will continue to do our utmost to increase the understanding of people of Fukushima and society at large regarding the handling of ALPS treated water as part of the decommissioning work, by focusing on our efforts to disseminate information based on scientific evidence to parties within and outside Japan in an easy-to-understand manner and taking every opportunity to listen to the concerns and opinions of the public and explain our approach and response.
While construction of ALPS treated water dilution/discharge facilities, etc. will begin on August 4, 2022, with safety as the top priority, we will also work to build trust of people within and outside Japan, by responding sincerely to safety confirmation by municipalities and reviews by the International Atomic Energy Agency (IAEA) and disclosing the construction status as appropriate to secure objectivity and transparency.
