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 October 17, 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.
* The underlined parts are the updates from the previous press release.
[Nuclear Power Station]
·Fukushima Daiichi Nuclear Power Station: Unit 1 to 3: shut down due to the
earthquake
(Units 4 to 6: outage due to regular inspections)
- At 5:31 pm on October 25, we started transferring the accumulated water
brought from the basement of turbine building of Unit 1 to the basement
of turbine building of Unit 2.
- At 5:48 pm on October 25, we adjusted the rate of water injection to Unit
1 reactor from approximately 3.0 m3/h to approximately 3.8 m3/h following
the alert that showed decrease of water injection at 6:10 pm on the same
day.
- At 6:52 pm on October 25, we adjusted water injection rate through
reactor feed water system at 3.0 m3/h, since we observed decrease in
water injection. (Injection rate through core spray system remains at
approx. 7.0 m3/h.)
·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.
