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 12:45 am on June 21, we started a water flow test using highly 
 concentrated contaminated water in Cesium adsorption Instruments of the 
 water treatment facility. At approximately 7:20 am on the same day, a 
 pump transferring filtrated water to coagulation settling instrument 
 tripped, and water treatment facility stopped. At approximately 11:30 am 
 on the same day we restarted the pump that had tripped due to overload of 
 high flow rate on the recirculation side. 
-At approximately 12:16 pm on June 21 we resumed the operation of the 
 water treatment facility. At approximately 12:30 pm on the same day it 
 reached the rated capacity. 
-At 11:55 am on June 21 we temporarily stopped operating the nitrogen 
 supply equipment to Unit 1 Primary Containment Vessel due to work to 
 install a transformer in the Power Station. 
-At 10:02 am on June 21 we changed the rate of water injection to Unit 1 
 Reactor from approx. 4.5 m3/h to approx. 4.0m3/h through reactor feed 
 water system piping arrangement. 
-At 10:04 am on June 21 we changed the rate of water injection to Unit 2 
 Reactor from approx. 5 m3/h to approx. 4.5m3/h through reactor feed water 
 system piping arrangement. 
-At 10:06 am on June 21 we changed the rate of water injection to Unit 3 
 Reactor from approx. 11 m3/h to approx. 10m3/h through reactor feed water 
 system piping arrangement. 
-At 9:49 am on June 20, in order to lower dose during work at 5FL, R/B, 
 Unit 4, we started freshwater injection to Reactor well and equipment 
 storage pool. At 12:52 pm on June 21 the injection was stopped. 
-At 10:00 am on June 21, we started transferring accumulated water in the  
 basement of the turbine building of Unit 6 to the temporary storage tanks. 
-On June 21, we are spraying dust inhibitors to yards around Unit 5 in 
 order to prevent scattering of radioactive materials on the ground by a 
 crawler dump truck. 
 On June 21, workers are spraying dust inhibitors to materials yards etc..

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

[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.
