Press Release (Jun 23,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 9:00 AM, June 23)
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 10:04 am on June 22nd, we changed the volume of water injection from 
 feed water system piping arrangement into the reactor of Unit 2 from 
 approx. 4.5 m3/h to approx. 4.0m3/h. After that the indicated value of 
 injection flow was fluctuating, however it settled at approximately 
 3.5m3/h now. 
-At 2:31 pm on June 22nd, we injected fresh water into the spent fuel pool 
 of Unit 4 through an alternative water injection line. At 4:38 pm, we 
 stopped injection. 
-At 10:00 am on June 22nd, we began to transfer the accumulated water in 
 the basement of the turbine building of Unit 6 to temporary tanks. At 
 4:00 pm, we stopped transfer. 
-At 0:43 am on June 23rd, after implementation of changing filters and 
 flushing system etc. of Cesium adsorption Instruments, we resumed the 
 operation of water treatment system. 
-On June 22nd, with a crawler dump, we sprayed dust inhibitor that 
 prevents radioactive materials from flying apart on the east side of the 
 turbine building of Unit 6 for approximately 6,400 m2. On the same day, 
 we also sprayed dust inhibitors around the south of bank protection etc 
 for approximately 5,160 m2.
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.
