Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March
11th 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 17th, we have put together the roadmap towards restoration from the
accident. 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 from previous press release 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 9:01 am on May 10th, in order to switch the water injection line to the
nuclear reactor of Unit 3 to the reactor feed water system piping
arrangement, we temporarily suspend transferring water from the trench of
the turbine building of Unit 2 to Centralized Radiation Waste Treatment
Facility. At 3:20pm on May 12th, we restarted the transfer.
-At 10:00am on May 12th, we restarted transferring accumulated water on the
basement in the turbine building of Unit 6 to the Radiation Waste
Treatment Building. At 4:00pm on the same day, we stopped the pumps for
the transfer.
-From 10:30am from 12:30pm on May 12th, we transferred accumulated water on
the basement in the reactor building of Unit 6 to the Radiation Waste
Treatment Building (approximately 7.5m3).
-On May 12th, we sprayed the dust inhibitor to approximately 5,250m2 areas
including nearby Solid Waste Storing Facility in a conventional way .
Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquake
Kashiwazaki Kariwa Nuclear Power Station:
Units 1, 5, 6, 7: normal operation
(Units 2 to 4: outage due to regular inspection)
[Thermal Power Station]
-Hirono Thermal Power Station Unit 2 and 4: Shutdown due to the earthquake
-Hitachinaka Thermal Power Station Unit 1: Shutdown due to the earthquake
[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.
[Avoidance of further Implementation on Planned Rolling Blackouts and
Request for Conserving Electricity Consumption]
Currently, we are working to restore electricity supply after our nuclear
and thermal power facilities were severely damaged by Tohoku-Chihou-
Taiheiyou-Oki Earthquake. The widespread understanding and cooperation of
our customers to conserve electricity have contributed to the improvement
of this tight power supply-demand balance situation.
Amidst this backdrop, since the electricity supply will be able to balance
with the demand for the time being, we have decided not to implement
further rolling blackouts in principle.
However, we sincerely ask for your continued cooperation in reducing
electricity consumption due to the possible increase in demand caused by
warmer weather or unexpected trouble at power stations that are currently
being restored to service. In case the electricity supply-demand balance
becomes tighter than expected, we may regrettably need to restart the
implementation of rolling blackouts, with prior notice. We kindly ask for
your cooperation.
We will do our best to maintain this policy of avoiding further
implementation of rolling blackouts during the summer.
