Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 
11th 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 17th, we have compiled the roadmap towards restoration from the 
accident and then we updated the roadmap considering the current situation, 
on May 17th. 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 2:20 pm on June 8, the main control room lights of unit1/2 went out. 
  At 2:35 pm, a part of power panel suspended. At 2:49 pm, monitoring post 
  (MP7/8) transmission path were suspended. At 2:57 pm, nitrogen supply 
  facilities were halt due to pressure rise. Causes are currently under 
  investigation. 
- At 9:00 am on June 8, we suspended the Residual Heat Removal System Pump 
  (C) in order to increase one more pump. Two pumps resumed at 0:35 pm on 
  the same day. 
- The accumulated water transfer from the basement of the unit 6 turbine 
  building to Centralized Radiation Waste Treatment Facility (Process Main 
  Building) was implemented from 10:05 am to 0:40 pm on June 8. 
- On June 8, using a concrete pumping vehicle, we have implemented 
  spraying dust inhibitor, which prevents the radioactive materials from 
  dispersing, to the roof and the wall of Unit 1's turbine building. 
- On June 8, dust inhibitor was sprayed at observation point area.
 
Fukushima Daini Nuclear Power Station: 
       Units 1 to 4: shutdown due to the earthquake 
 
- At 4:00 pm on June 7, air leak was found at the weld zone of unit 4's 
  main emission duct by TEPCO employee. (10cm×3cm 2 places ). Radioactive 
  materials in the air were below measurable limits. No outlier at main 
  emission monitor and monitoring post. The repair work will be 
  implemented soon.
 
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 seems that planned outage could be escaped thanks to your understanding
for brownout.
 
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 for brownout.
