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 roadmap considering the current situation, on June
17. 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 6:27 pm on June 23rd, regarding the water injection line to the reactor
of each unit, we changed for Unit 1 and Unit 2 by using electrical reactor
water injection pumps for Unit1, and stopped electrical reactor water
injection pumps for Unit 2.
- At 9:32 am on June 23rd, fresh water injected to reactor well and dry
separator pit of Unit 4 and finished at 3:29 pm.
- On June 23rd, dust inhibitor that prevents radioactive materials from
flying apart sprayed on the north side of the ultra high voltage switching
yard of Unit 5 and 6 for the area of 5,160m2.
Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquake
- At 2:45 pm on June 23rd, at check point of service building of Unit 1 and
Unit 2, a security agent, who attended materials taking out, caught his
clothing to the fire extinguisher on the wall and dropped to injure right
foot little finger. The security agent was transferred to the J-village
and arrived at 3:58 pm. After treatment of doctor, transferred at 4:30 pm
to Sogo Iwaki Kyoritsu Hospital by ambulance. No contamination was found
due to the body survey.
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
[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]
We have worked to restore electricity supply after our nuclear and thermal
power facilities were severely damaged by Tohoku-Chihou-Taiheiyou-Oki
Earthquake. This time, we revised that the supply capacity in this summer
would increase because we could plan to secure an additional capacity.
However, in order to maintain the policy of avoiding further implementation
of rolling blackouts during the summer, in addition to the above increase
of the supply capacity, we sincerely ask for your continued cooperation in
reducing electricity consumption. Now we are creating concrete measures
considering "Outline of Countermeasures for Power Supply and Demand During
Summertime" presented by the Electricity Supply-Demand Emergency Response
Headquarters of the Japanese government.
(Previously Announced)
It is expected that we will be able to maintain the policy of avoiding
further implementation of planned blackouts this June because it is
estimated that we will be able to secure the capacity exceeding the
maximum forecasted demand as of now, thanks to your understanding as well
as cooperation on saving electricity.
However In the event that an unplanned outage such as excessive continuous
operation in old plants and a sudden increase of power demand due to unusual
hot temperature occur, there is a possibility to affect a stable power
supply. In order to maintain the policy of avoiding rolling blackouts, we
steadily implement to install additional power capacity we have planed, and
we continuously do our best efforts to secure supply capacity. We apologize
for the inconvenience this may cause and appreciate for your cooperation to
save electricity.
