Press Release (Jun 20,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00 PM, June 20)
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 8:51 pm on June 19 we began to open the air lock, while coordinating 
 a degree of its opening. Then we confirmed a result of monitoring dose 
 rate in the air and evaluated there was no impact in the surrounding 
 area. At 5:00 am on June 20 we fully opened the air lock. At 2:30 pm on 
 June 20, we opened the large equipment carry-in entrance of R/B. 

·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 10:25 am on June 20, conducted a water flow test using highly 
 concentrated contaminated water in Cesium adsorption Instruments of the 
 water treatment facility and finished it at 2:50 pm on the same day. 

·At 1:37 pm on June 20, we started transferring accumulated water in the 
 basement of the turbine building of Unit 2 to Condenser, turbine building, 
 Unit 1. 

·At 10:00 am on June 20, we started transferring accumulated water in the 
 basement of the turbine building of Unit 6 to the temporary storage tanks. 

·At 10:00 am on June 20, we started operation of the circulating seawater 
 purification facility installed at the screen area, Units 2 and 3. 

·On June 20, we are spraying dust inhibitors to yards around Unit 5 in 
 order to inhibit scattering of radioactive substances on the ground by a 
 crawler dump truck. 
 On June 20, 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.
