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.
*Underlined are new items
[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 6:56 pm on August 30, as we confirmed that the rate of water injection
to the reactor of Unit 2 dropped, we adjusted the rate to approx. 3.8㎥/h.
*In order to modify the software, at 3:32 am on August 30, we stopped the
evaporative concentration apparatus 2A. At 4:16 am, we stopped the
evaporative concentration apparatus 2B. After that, at 7:09 am on the
same day, we stopped the desalination facility (RO) 1A. At 7:16 am, we
stopped the desalination facility (RO) 2. We started the desalination
facility (RO) 1A at 12:28 pm, and the desalination facility (RO) 2 at
12:42 pm on the same day. We started the evaporative concentration
apparatus 2B at 3:44 pm and the evaporative concentration apparatus 2A
at 4:34 pm on the same day,
- 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 August and September, we forecast the maximum supply will be 56.1 GW,
and the assumed peak demand 48.9 GW.
We apologize for the inconvenience this may cause and appreciate for your
cooperation to save electricity.
