Press Release (Jun 28,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 9:00 AM, June 28)
 
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 4:20 pm on June 27, the operation of circulation injection cooling was 
 initiated by injecting water from the filter water tank as well as usage 
 of the treated water regarding water injection to reactor for Unit 1, 2 
 and 3. At 5:55 pm, since we confirmed a leakage from the pipe which 
 supplies water from treated water tank to injection pump of reactor, we 
 stopped supplying treated water. 

-At 8:23 am on June 27, due to the changeover of power source inside the 
 power station, we temporarily stopped Spent Fuel Pool Cooling and 
 Purification System, Unit 2. At 4:53 pm, we resumed the operation. 

-At 9:02 am on June 27, due to the changeover of power source inside the 
 power station, we temporarily stopped transfer of paddle water from the 
 pit, Unit 2 to Central Radioactive Waste Disposal Facility. At 5:07 pm, 
 we resumed the operation. 

-At 3:00 pm on June 27, we began injecting boric acid into Unit 3 spent 
 fuel pool through Spent Fuel Pool Cooling and Filtering (Clean up) System. 
 At 5:18 pm, we finished the injection. 

-At 3:32 pm on June 21, we started transferring accumulated water in 
 turbine building of Unit3 to central waste treatment facility building. 
 At 3:44 pm on June 27, we suspended the operation of transferring pumps. 
 At 5:00 pm, we resumed the operation of 2 transferring pumps. 

-On June 27, dust inhibitor is being sprayed on the east side of the 
 turbine building of Unit 5 and 6 in the range of approximately 5,300㎡ by 
 a crawler dump truck to prevent diffusion of radioactivity materials 
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 planned 
blackouts, we will steadily implement installation of additional power 
capacity as we have planned, 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.
