Press Release (May 12,2011)
7Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake(as of 4:00 PM, May 12)
 
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.
