Press Release (Jun 17,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 3:00 PM, June 17)
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 May 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 10:00 AM on June 17, we completed a repair on the bad condition 
  occurred in the cesium absorption equipment. At 13:00 PM on the same day, 
  we started an operation of pumping of the equipment.  
· At 2:20 PM on June 17, we started a water transfer from the vertical 
  shaft of Unit 2 to the surface condenser of Unit 1. Because we confirmed 
  that water did not flow, we interrupted the transfer at 2:59 PM on the 
  same day. Now we are investigating for the causes.  
· At 10:19 AM on June 17, we started an injection of fresh water to the 
  spent fuel pool of Unit 3 using the fuel pool cooling and filtering 
  system (hydrazine had been injected from 10:23 AM to 11:31 AM on the 
  same day). We completed the work at 11:57 AM on the same day.  
· At 10:00 AM on June 17, we started a water transfer from the underground 
  floor of the turbine building of Unit 6 to temporary water tanks.  
· On June 17th, workers have sprayed dust inhibitor in the ground.  
 
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.
