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 August 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.
*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)
* At approximately 8:18 am on September 15, we found a partner company
worker unequipped with a charcoal filter to the full-faced mask after the
worker entered the site of Fukushima Daiichi Nuclear Power Station. Then,
as a result of the measurement by whole body counter, we have confirmed
that the worker did not take in any radioactive materials.
* At 9:44 am on September 15, we stopped transfer of the accumulated water
from the basement of the turbine building of Unit 3 to Centralized
Radiation Waste Treatment Facility (Miscellaneous Solid Waste Volume
Reduction Treatment Building [High Temperature Incinerator Building]),
and restarted transfer to Centralized Radiation Waste Treatment Facility
(Process Main Building).
* At 10 am on September 15, we restarted transfer of the accumulated water
from the basement of the turbine building of Unit 6 to the temporary tank.
* At 9:56 am on September 15, we restored and restarted the seawater pump
of Equipment Cooling Water System of Unit 6. At 2:33 pm on the same day,
we completed the adjustment of the flow rate of Fuel Pool Cooling System
and started cooling the spent fuel pool. Consequently, the reactor and
the spent fuel pool are now separately cooled through Residual Heat
Removal System and Fuel Pool Cooling System respectively.
- 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.
