Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March
11, 2011, TEPCO's facilities including our nuclear power stations have been
severely damaged. We deeply apologize for the anxiety and inconvenience
caused.
With regard to the accident at Fukushima Daiichi Nuclear Power Station, on
April 17, we have compiled the roadmap towards restoration from the
accident and then we updated the progress status of roadmap considering
the current situation, on July 19. Accomplishment of the Step1 target
"Radiation dose is in steady decline" has been confirmed. On September 20,
we updated the further progress.
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.
* Updates are 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)
* In order to repair the outlet valve of Unit 5 residual heat removal
system seawater pump (D), from 9:45 am to 10:42 am, September 26, we
switched the seawater pump from B system (permanently installed) to A
system (temporarily installed).
* We restarted transferring the accumulated water from the basement of the
Unit 6 turbine building to the temporary tank at 10:00 am, September 26.
* One of the staff from the cooperating companies was injured catching his
forth finger between the steel stocks in site of the power plant
(outdoors) at 11:05 am, September 26. The staff returned to the office
outside the site and headed for the emergency medical office with a
surgical mask on. We are planning to conduct a measurement with a whole
body counter, because the possibility of radioactive materials intake
cannot be denied. Contamination on the surface of the body and the
surgical mask is not detected.
- Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquake
- Kashiwazaki Kariwa Nuclear Power Station:
Units 5, 6: under normal operation
(Units 1 to 4 and 7: outage due to regular inspections)
[Thermal Power Station]
- Power supply has returned to normal and facilities damaged by the
earthquake are now being handled in a timely manner.
[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.
[Impacts on Power Supply and Demand Balance]
Thanks to our all customer's energy-saving efforts, we could successfully
maintain an even supply-demand balance in this summer. We express our
deepest appreciation to the efforts.
While we will continue to exert maximum effort to stabilize the supply-
demand balance, we kindly request your continued efforts in keeping
electricity consumption within reasonable levels.
