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 9:06 pm on October 19, in the water treatment facilities under
operation, a SMZ pump of the 4th process line of cesium adsorption
apparatus automatically stopped. A pump of the 3rd process line is
continuously operated. Water treatment by the cesium adsorption
apparatus is also continuously operated at the flow rate approx. 17m3/h
(the flow rate before the automatic stop was approx. 20m3/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.
