IAEA Delegation Visits Japan for the Second Mission to TEPCO and METI under the Safety Review of the Handling of ALPS Treated Water at TEPCO’s Fukushima Daiichi Nuclear Power Station
From 14th to 18th November, an IAEA delegation, composed of IAEA officials and international experts, visited Japan to conduct a mission focused on TEPCO and METI, under the auspices of the IAEA’s Safety Review on ALPS treated water at TEPCO’s Fukushima Daiichi Nuclear Power Station (FDNPS).
- This is the second IAEA review mission of safety aspects of the ALPS treated water. The first mission was conducted from 14th to 18th February this year.
- The delegation reviewed technical aspects related to the contents of “Application Documents for Approval to amend the Implementation Plan for Fukushima Daiichi Nuclear Power Station Specified Nuclear Facility” and the revised Radiological Environmental Impact Assessment (REIA) report submitted by TEPCO to the Nuclear Regulation Authority (NRA) on 14th November of this year based on the IAEA safety standards. The report of the review mission is expected to be issued by the IAEA at the beginning of 2023. The points raised by the IAEA review as well as its observations provided in other meetings will be reflected in TEPCO’s review of the REIA Report to further enhance its contents.
- On 16th November, the delegation visited the TEPCO’s FDNPS to review progress of the construction work related to the discharge of Advanced Liquid Processing System (ALPS) treated water, such as in harbor area where facilities for dilution and discharge of the treated water are to be installed, and so on.
- The Government of Japan will continue to support the IAEA in its review of the safety of the discharge of ALPS treated water. The Government of Japan also remains committed to making efforts to promote better understanding in the international community regarding the handling of ALPS treated water.

ALPS treated water is water which is processed by devices such as ALPS (Advanced Liquid Processing System) to ensure that the concentration of the radioactive materials other than tritium surely meet the regulatory standards for safety. In addition, it is planned that ALPS treated water will then be sufficiently diluted before the discharges into the sea so that concentration of all radioactive materials including tritium will be far below the regulatory standards for safety.
