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 4:36pm on May 5th, we started to ventilate with 6 local exhausters
the reactor building of Unit 1 in order to improve the working
environment of the building.
-From 12:19pm to 8:46pm on May 5th, we implemented water spray to the
spent fuel pool of Unit 4 by a concrete pumping vehicle.
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.
