Considering the Basic Policy on handling of ALPS treated water at the Tokyo Electric Power Company Holdings' Fukushima Daiichi Nuclear Power Station decided by the Japanese government in April 2021, TEPCO had been reviewing the details of the design and operation of facilities for securing safety 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. And, on December 21, 2021, we submitted the "Application Documents for Approval to Amend the Implementation Plan for Fukushima Daiichi Nuclear Power Station Specified Nuclear Facility" for the basic design of ALPS treated water dilution/discharge facility and related facilities to the Nuclear Regulation Authority.

Thereafter, the Nuclear Regulation Authority pointed out items pertaining to the implementation plan on the discharge of ALPS treated water during review meetings. In light of the items that were brought up, on April 28, 2022, TEPCO submitted a partially revised "Application Documents for Approval to Amend the Implementation Plan for Fukushima Daiichi Nuclear Power Station Specified Nuclear Facility" (hereinafter referred to as, "Partial Revision (first revision)") to the Nuclear Regulation Authority.
In light of the Nuclear Regulation Authority's comments on the Partial Revision (first revision), on May 13, 2022, TEPCO submitted a partially revised "Application Documents for Approval to Amend the Implementation Plan for Fukushima Daiichi Nuclear Power Station Specified Nuclear Facility" (second revision) to the Nuclear Regulation Authority.

(Announced as of May 13, 2022)

In light of the Nuclear Regulation Authority's comments on the Partial Revision (second revision) etc., today, TEPCO submitted a partially revised "Application Documents for Approval to Amend the Implementation Plan for Fukushima Daiichi Nuclear Power Station Specified Nuclear Facility" (third revision) to the Nuclear Regulation Authority.

We will continue to thoroughly implement measures related to the handling of ALPS treated water based on the Japanese government's basic policy while continuing to carefully listen to the opinions from parties concerned so as to further ensure safety.
