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)
* From 9:15 am to 0:10 pm on September 14, we sampled gases in the Reactor
Pressure Vessel of Reactor Building, Unit 1.
* At 9:47 am on September 14, we stopped the Spent Fuel Pool's
desalination system of Unit 4 to install an electric dialysis equipment.
At 0:25 pm on the same day, the desalination system resumed while we
continued operation of an alternative system to cool down the pool.
* At 9:53 am on September 14, we stared transfer of the accumulated water
from the condenser to the basement of Turbine Building of Unit 1.
* At 11:08 am on September 14, the Common Pool's cooling system was
shutdown to move a Common Pool Power Center so that we will replace a
power panel installed at the basement of Spent Fuel Common Pool.
* At 0:40 pm on September 1, we found 4 out of 6 partner company workers
contaminated when we were decontaminating the full-face masks of the
workers who were engaged in maintenance work of the water processing
system. By the use of whole body counter, we will check if they have
take in radioactive materials.
* At 2:59 pm on September 14, we will start injecting water into the
Reactor of Unit 2 through the core spray system. At 3:25 pm on the same
day, we adjusted the volume water at 1.0 m3/h. The volume of water
injected from the feed water system remains unchanged.
- 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.
[Perspective of Power Supply and Demand Balance in this summer]
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.
