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 6:26 pm on June 5, we started transferring the accumulated water at  
  the basement of Turbine Building of Unit 3 to the condenser.  
- On June 5, our workers sprayed dust inhibitor to areas with the size of  
  approximately 8,750 m2, including observation point.  
- Approximately 10 am on June 5, a partner company's worker (equipped with  
  overalls, Tyvek, and full-face mask) reported that he felt sick during  
  the power-cable installation task near the Wild bird forest in the power  
  plant's premise. After physical examination at the medical treatment room  
  of Fukushima Daiichi Nuclear Power Station, he was taken to J-VILLAGE by  
  ambulance at approximately 10:37 am. At 11:20 am, a helicopter emergency  
  medical service was requested by J-VILLAGE. After transported to Hirono  
  Central Gymnasium by ambulance, the worker was transported to Iwaki  
  Kyouritsu Hospital by the helicopter service. According to the physical  
  examination, it was explained that he was suspected to suffer from  
  "dehydration," and needs treatment in the hospital about a week. Besides  
  him, around 10:15 am on the same day, another partner company's worker  
  (in the same equipment as the one of the above worker) reported that he  
  felt sick during the similar work. After physical examination at the  
  medical treatment room of Fukushima Daiichi Nuclear Power Station, he  
  was transported to J-VILLAGE by ambulance at approximately 12:07 pm  
  because of his serious condition. At 12:40 pm, he was transported to  
  Fukushima accident Hospital from J-VILLAGE by ambulance. After the  
  physical examination, he was diagnosed to suffer from dehydration, and  
  to be requested to keep quiet in bed at home for three days.  
 
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) 
 
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.
