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) 

- Installation work of exhauster was initiated in order to improve the 
  work environment in the reactor building of Unit 1 
- At 10:05 am on May 2nd, water injection to spent fuel pool of Unit 2 by 
  motor driven pump was initiated. Injection was finished at 11:40 am. 
- At 2:00 pm on May 1st, transfer of accumulated water in Unit 6 turbine 
  building to a temporary tank was initiated. At 5:00 pm, transfer pump 
  was stopped (approximately 120 m3). At 10:00 am on May 2nd, transfer was 
  restarted. 
- On May 2nd, unmanned crawler dump truck has sprayed dust inhibitor in 
  the south and west side of the reactor building of Unit 4. We have also 
  sprayed dust inhibitor to the slope surrounding the former 
  Administration Office building by conventional method. 
      In previous announcements, we described the building as "the turbine 
      building of Unit 4," but it was an error. We meant "the reactor building  
      of Unit 4." We would like to apologize for the error and correct it. 

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 
  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.
