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 12:40 pm on September 14, we found the inside of
full-face masks, which were used by 4 out of 6 partner company workers,
contaminated when we were checking the contamination of the masks used in
maintenance work of the water treatment system. Then, as a result of the
measurement by whole body counter, we have evaluated that no one took in
radioactive materials.
* At approximately 4 pm on September 14, a TEPCO employee who returned from
the patrol on the generators of Unit 1 - 4 (outdoors) to Visitors Hall of
Fukushima Daini Nuclear Power Station got decontaminated since
contamination at his chin and neck was detected. Then as a result of thev
measurement by whole body counter, we have evaluated that no radioactive
materials was taken in.
* At 3:58 am on September 13, we stopped the operation of cesium adsorption
instruments and decontamination instruments for the maintenance of the
water treatment facility. At 6:16 pm on September 14, we started those
instruments, and the rated flow was achieved at 7:20 pm.
* 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. We
will check the worker by whole body counter if he took in radioactive
materials.
- 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.
