Press Release (Apr 19,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 4:00PM, April 19th)
Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March
11th 2011, TEPCO's facilities including our nuclear power stations have
been severely damaged. We deeply apologize for the anxiety and inconvenience
With regard to the accident at Fukushima Daiichi Nuclear Power Station, on
April 17th, we have put together the roadmap towards restoration from the
accident. By bringing the reactors and spent fuel pools to a stable cooling
condition and mitigating the release of radioactive materials, we will make
every effort to enable evacuees to return to their homes and for all
citizens to be able to secure a sound life.

Below is the status of TEPCO's major facilities.
*New items have been underlined
[Nuclear Power Station] Fukushima Daiichi Nuclear Power Station: Units 1 to 3: shutdown due to the earthquake (Units 4 to 6: outage due to regular inspections) * From 10:17 am to 11:35 am on April 19th, the spent fuel pool of Unit 4 was sprayed with water using the concrete pumping vehicle. * From 11am to 3pm on April 19th, draining water from the basement of the turbine building of Unit 6 was transferred into the condenser. * At 10:23 am on April 19th, connection work between high voltage switchgear of Unit 1&2 and Unit 3&4 was completed. * On April 18th, in terms of the transfer of high level radioactive wastewater to the Centralized Radiation Waste Treatment Facility, measures to prevent leakage in the facility building was completed. After reporting the necessity of the transfer, the assessment of safety and principle of the permanent storage of the wastewater and treatment facility to Minister of Economy, Trade and Industry with the confirmation by Nuclear and Industrial Safety Agency, the wastewater transfer from the vertical shaft of the turbine building of Unit 2 to the Centralized Radiation Waste Treatment Facility was started from 10:08 am on April 19th.
Fukushima Daini Nuclear Power Station: Units 1 to 4: shutdown due to the earthquake
Kashiwazaki Kariwa Nuclear Power Station: Units 1, 5, 6, 7: normal operation (Units 2 to 4: outage due to regular inspection)
[Thermal Power Station] - Hirono Thermal Power Station Units 2 and 4: Shutdown due to the earthquake - Hitachinaka Thermal Power Station Unit 1: Shutdown due to the earthquake - Kashima Thermal Power Station Unit 6: Shutdown due to the earthquake
[Hydro Power Station] - Power supply has returned to normal and facilities damaged by the earthquake are now being handled in a timely manner.
[Impacts on Transmission Facilities] - Power supply has returned to normal and facilities damaged by the earthquake are now being handled in a timely manner.
[Avoidance of further Implementation on Planned Rolling Blackouts and Request for Conserving Electricity Consumption] Currently, we are working to restore electricity supply after our nuclear and thermal power facilities were severely damaged by Tohoku-Chihou- Taiheiyou-Oki Earthquake. The widespread understanding and cooperation of our customers to conserve electricity have contributed to the improvement of this tight power supply-demand balance situation. Amidst this backdrop, since the electricity supply will be able to balance with the demand for the time being, we have decided not to implement further rolling blackouts in principle. However, we must sincerely ask for your continued cooperation in reducing electricity consumption due to the possible increase in demand caused by warmer weather or unexpected trouble at power stations that are currently being restored to service. In case the electricity supply-demand balance becomes tighter than expected, we may regrettably need to restart the implementation of rolling blackouts, with prior notice. We kindly ask for your cooperation. We will do our best to maintain this policy of avoiding further implementation of rolling blackouts during the summer.
