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 10:06 am on June 28, we stopped operation of water treatment 
  facilities and conducted flushing of systems etc. At 12:24 pm, we 
  resumed the operation. 

- At 11:47 am on June 28, we adjusted injection rate from feed water 
  system piping arrangement to approximately 3.5m3 since decrease in 
  amount of water injection at the reactor of Unit 1 was confirmed. 

- At 9:58 am on June 28, we stopped transferring accumulated water in 
  turbine building basement of Unit 3 to central waste treatment facility 
  building. 

- At 9:40 am on June 28, we started injecting fresh water to reactor dry 
  well and dry separator pit. 

- We started operations for emergency diesel generator (A) at 6:03 pm on 
  June 28 and emergency diesel generator (B) at 12:32 pm on June 28 
  respectively in Unit 5. 

- At 12:00 pm on June 28, TEPCO worker found the water level gauge 
  (manometer) of temporary tank where accumulated water from turbine 
  building in Unit 6 is being transferred lying on the floor. Since 
  accumulated water in temporary tank that is from turbine building 
  basement at Unit 6 was leaking from the gauge, we stopped it by closing 
  main valve. The amount of water leaked was approximately 15m3. For 
  safety, we measured surface dose rate around and confirmed the result to 
  be equivalent to that of surrounding area (7μSv/h). Currently, we are 
  investigating the details. 

- On June 28, dust inhibitor is being sprayed around filtrate water tank.

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
maximumforecasted 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.
