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 2:53 pm on September 7, as it was confirmed that there was a decrease
in the amount of water injection for the reactor of Unit 1, we adjusted the
rate of water injection to approx. 3.8 m3/h
*At 10:00 am on September 7, we started transferring accumulated water at
Unit 2 condenser to the basement of Unit 2 turbine building.
*At 2:55 pm on September 7, as it was confirmed that there was a decrease
in the amount of water injection for the reactor of Unit 2, we adjusted the
rate of water injection to approximately 3.8 m3/h
*At 2:46 pm on September 7, we adjusted the rate of water injection for the
reactor of Unit 3 through reactor feed water system piping arrangement to
approx. 5.0 m3/h. (Water injection through core spray system continues at
approx. 3.0 m3/h.)
*At 10:19 am on September 7, we started transferring accumulated water from
Site bunker building to Process main building at Centralized Radiation
Waste Treatment Facility.
-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]
-In September, we forecast the maximum supply will be 55.6 GW, and the
assumed peak demand 46.06 GW.
We apologize for the inconvenience this may cause and appreciate for your
cooperation to save electricity.
