Press Release (Apr 28,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 9:00AM, April 28)
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.
*New items have been 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) 

*In order to identify the appropriate injection amount of water in making
 the fuels submerged in water, at 10:02 am on April 27th, we started the
 operation to gradually change the injection amount of water to the 
 reactor of Unit 1 from approx. 6 m3/h to approx. 14 m3/h at a maximum. 
 We are injecting approx 10 m3/h of water to the reactor at 9:00 am, 
 April 28th.  
*At 12:18 pm on April 27th water spray by a concrete pumping vehicle to 
 the spent fuel pool of Unit 4 was started, and suspended at 2:01 pm. At 
 2:32 pm water spray was resumed and finished at 3:15 pm, April 27th.  
*Out of the soil samples gathered on March 28th, we conducted the 
 nuclides analysis on two samples from which Plutonium were detected to 
 confirm Americium and Curium. We detected Americium 241 and Curium 242, 
 243 and 244.  
*On April 27th, we sprayed approx 7,500m2 of the dust inhibitor to the 
 seaside area of Unit 3 by a remote controlled crawler dump truck.  
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 Units 2 and 4: Shutdown due to the
- Hitachinaka Thermal Power Station Unit 1: Shutdown due to the 
[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.
