Increasing transparency of business operations

TEPCO actively discloses information on business activities and plant operations to all stakeholders via TV commercials, websites, pamphlets, and other such means, to increase the transparency of business operations.

Timely and proper disclosure of corporate activity information

We provide information on daily business activities of the TEPCO Group to the media via press releases and press conferences. The information is also posted on our website to ensure prompt and accurate information disclosure.

Publicity and public relations activities using mass media

We make active use of TV/radio commercials, newspaper advertisements, and other mass media to provide a wide range of information to society, including useful consumer information, such as tips on efficient uses of electric products, and our initiatives toward realizing a low-carbon society.

Disclosure of nuclear power station information

TEPCO strives to earn the trust and confidence of local residents in communities that are home to its nuclear power station, as well as of the wider society, by disclosing information on various aspects of its station in a prompt and easy-to-understand manner.

Active disclosure of information

As part of our active effort to disclose information about our nuclear power station, we convey real-time information on the operational status of our power station via website, and provide information on daily safety and quality assurance activities implemented at the station, through newspaper advertisements and periodic PR magazines intended for local residents.
We also provide free access to information about nuclear power generation at our nuclear power information centers located in the communities of each of our nuclear power station.

Monitoring of radiation and radioactive substances

Radiation levels and the concentration of radioactive substances released to the environment are closely monitored in each nuclear power plant. Monitoring posts that monitor atmospheric radiation around the clock are installed in the perimeter of power station, and data acquired from them are posted on our website in real time.
Furthermore, seawater, soil, and agricultural products from around our nuclear power station are regularly sampled to measure the amount of radioactive substances they contain and examine any impacts that nuclear operations may have on the surrounding environment. The findings are reported to the local government and also widely disclosed to the public.

Disclosure of nonconformity events

Information on nonconformities that occur at nuclear power station, including troubles and failures, is disclosed to the public via press releases and our website, based on TEPCO Information Disclosure Criteria (disclosure standards). The standards require nuclear power station to disclose and provide updates of serious nonconformities that are legally required to be reported, minor nonconformities not subject to reporting under the law, and daily maintenance information.
