Due to the Tohoku-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. 
 
Below is the status of TEPCO's major facilities. 
*New items 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 1:15PM, April 13th, we started injecting fresh water to Spent Fuel 
 Pool of Unit s from Fuel Pool Cooling line and finished at 2:55PM of the 
 same day 
 
*From 7:35PM on April 12, we started transferring accumulated water in 
 Turbine Building from the trench of Unit 2 to the condenser. At 11:00AM 
 on April 13, we stopped transferring accumulated water to check whether 
 there was water leakage from condenser or not. We didn't find any problem, 
 so we restarted transferring at 3:02PM of the same day. 
 
* In order to prevent water containing radioactive materials from spilling 
 from a plant's port to the sea, we installed 120 meter wide double silt 
 fences around a breakwater on the south of the station at 10:45 am on 
 April 11. On April 12th and 13th, we installed three iron plates in front 
 of Unit 2 screen. At 1:50pm on April 13th , we installed a silt fence in 
 front of Unit 3 and 4 screen. 
 
*At 11:00am on April 13th , we started spraying inhibitor in order to 
 prevent diffusion of radioactive materials on a trial basis and finished 
 at 11:30 am of the same day. 
 
* At 11:35 am, April 1st, a worker fell into the sea while stepping into 
 the ship from the pier during the hose laying work of the barge. Other 
 crew immediately rescued the worker. While no injury or contamination was 
 confirmed, whole body counter has been implemented to check the 
 contamination inside the body just in case and on April 12, we found 
 there was no contamination inside the body. 
 
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 
-Kashima Thermal Power Station Unit 6: 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-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, in principle, we have decided not to implement 
further rolling blackouts. However, we must 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, as 
stated, we may reluctantly restart the implementation of rolling blackouts. 
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.
