TEPCO Holdings’ Action in Response to theGovernment’s Policy on the Handling of ALPS
Treated WaterApril 16, 2021
Tokyo Electric Power Company Holdings, Inc.
※Correction made on April 19, 2021 (P8)Introduction
We deeply apologize for the immense burden and deep concern the TEPCO Holdings
Fukushima Daiichi Nuclear Power Station accident is causing the local residents and society atlarge. We would also like to offer our apologies for the string of recent incidents that have caused
concern about TEPCO’s nuclear operations and distrust in us as a company.
Recently, the Government of Japan published the “Basic Policy on handling of ALPS treatedwater at the Tokyo Electric Power Company Holdings’ Fukushima Daiichi Nuclear Power Station”(hereinafter government policy) at the 5th Inter-Ministerial Council for Contaminated Water,
Treated Water and Decommissioning Issues held on April 13.
We are taking seriously that this government policy on the handling of ALPS treated water was
put forth based on opinions expressed by parties concerned at various opportunities in addition
to the discussions held by the Subcommittee on Handling of ALPS Treated Water and theTritiated Water Task Force (hereinafter ALPS Subcommittee).
TEPCO Holdings will work to ensure our response is strictly based on this government policy.

TEPCO Holdings’ Approach to the Discharge of ALPS Treated Water
Basic position•In releasing ALPS treated water*1 into the sea, we will ensure that the discharged water is safe by conforming to safety standards
based on laws, and relevant international laws and practices, while conducting radiation impacts assessments on people and theenvironment*2 . Thus we will secure the safety of the public, the surrounding environment, and of agricultural, foresty and fisheryproducts.

Strengthening andenhancing the scope ofmonitoring•

In releasing ALPS treated water into the sea, we will enhance and strengthen our sea area monitoring efforts to minimize any
potential adverse impacts on reputation.

•We will secure objectivity and transparency in monitoring, requesting cooperation from experts and the people in the agricultural,forestry, fishery industry.

Preventing leaks
from tanks
Information
dissemination andminimizing rumors•

On-site tanks that store ALPS treated water will be continuously monitored for leaks and will be maintained and managed
appropriately in preparation for natural disasters.

•To mitigate concerns and foster understanding domestically and abroad, we will continuously disseminate accurate informationon the impacts of the ALPS treated water on the environment and the results of radiological impact assessment for public andenvironment in a transparent manner, which include the concentration of radioactive materials in the ALPS treated water andassessment results before it is discharged, progress in discharge and the results of sea area monitoring.

•To minimize any potential adverse impacts on reputation, we will do our utmost in supporting industries that may be subject topotential adverse impacts on reputation at each stage from production, processing, distribution, to consumption (develop newmarkets, etc.).

Appropriatecompensation•••

If reputational damage is incurred as a result of the discharge of ALPS treated water despite these efforts, we will provide swift
and appropriate compensation.

*1 Water that has been purified and treated by devices such as ALPS until radioactive materials other than tritium will surely satisfy the regulatory standards for safety.
*2 Includes any latent effects the ALPS treated water may have on the marine environment22.

Design and Operation of Necessary Facilities
Listening closely to the opinions of parties concerned, we will design and operatefacilities necessary for discharge of ALPS treated water into the sea by creating a plan tosteadily implement the government policy while preparing to obtain necessary approvals
from the NRA.

Site use plan
Necessary measures to discharge ALPS treatedwater consistently and to build facilities necessary indecommissioning will be closely studied given thegovernment policy.
Analysis of ALPS treated water
TEPCO will publish the concentration of tritium, 62
nuclides (nuclides subject to removal by ALPS), andcarbon-14 in ALPS treated water and the results ofassessments as well as the 3rd parties’
measurement and assessment results.

Emergency measures
Discharge will be stopped if the facilities
cannot perform their expected functions
due to failure or outages, or if abnormal
values have been detected in sea area
monitoring.

Seawater transfer pumpConcentration of tritium inside discharged water
The tritium concentration of the discharged water will beless than 1500 Bq/L. This will be assessed based on thetritium concentration in the ALPS treated water before
discharge and the amount of water it was diluted by.

Amount discharged
In the near term, discharge amounts
will be within the threshold of 22 trillion
Bq/year which is the target discharge
management value for Fukushima
Daiichi before the accident. This
amount will be reviewed as needed
basedonprogressmadeindecommissioning.

Environmental Monitoring

In addition to existing sea area monitoring of Cesium 137, we will be focusing on measuring and assessing
tritium.
Enhanced sea area monitoring will be started around a year before discharge of ALPS treated water isscheduled to start.
• In addition to conducting sea area monitoring according to the monitoring reinforcement plan, we will also
have third parties take measurements and publish them.
• We will ask that the agricultural, forestry, and fishery producers and local government officials participate in
and observe our sea area monitoring efforts.
• We will respond appropriately to the advice of the new meeting body to be established by the government
comprised of experts on the marine environment.

•S e awater We will increase the number of locations at which samples are collected and the frequency ofanalysis in monitoring tritium concentrations.

Fishes andSeaweeds

 We will analyze for tritium in addition to cesium which is currently being analyzed.
 We will increase the number of locations at which samples are collected and the frequency ofanalysis.

We will conduct fish feeding trials to provide empirical information about radioactivity in ALPS treated wateras part of environmental monitoring.

Review on the safety by the IAEA
We plan to receive reviews by IAEA experts before and after the start of thedischarge, and reflect appropriately IAEA’s guidance and advisory points to further
improve and strengthen our measures.

••Considering not just domestic legislations but also relevant international laws and practices, we plan toreceive reviews by IAEA experts which will cover the safety of the design of facilities and their operation
methods; the plan and implementation status of the sea area monitoring; the capability of the radiation
measurement of TEPCO; the assessment of radiological impact for the public and the environment, and soon.
TEPCO Holdings will study the specific design of facilities for transfer and dilution process and its operation,and prepare for the assessment of radiological impact for the public and the environment, to provide
information and explanations to the IAEA

If reputational damage is incurred as a result of ALPS treated water discharge despitemeasures to minimize any potential adverse impacts on reputation※, we will swiftly andappropriately compensate for the damages.
Basic approach・We will compensate for damages resulting from the discharge of ALPS
treated water without putting a restriction beforehand on thecompensation period, area or industry that can be compensated.
・When confirming the extent of damage, we will carefully listen to
circumstances of each individual case and will respond appropriately.
We will respond flexibly to minimize the impacts on the persons towhich the damage was sustained by infer the amount of damage using
rational means.
・We will carefully explain specific standards for compensation inresponse to the concerns of stakeholders and endeavor to reach anunderstanding. We will set up a dedicated inquiry desk to pick up onconcerns. We will listen and engage with each concern, considering thesituation of each parties concerned.
