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) 

·From 0:20 am on June 16, a continuous test operation of the whole water 
 treatment facilities started for low radiation level contained water. At 
 around 7:20 pm on June 16, the equipment of the facilities automatically 
 stopped. When we checked the equipment, we found a water leakage from 
 cesium absorption equipment. At this moment, we are under a recovery work 
 for the leakage. 
·From 10:00 am on June 16, transfer of accumulated water in the Unit 6 
 turbine building underground to the temporary tank was started. At 4:00 
 pm on June 16, the transfer was stopped.  
·From 1:14 pm on June 16, changing water feeding line from concrete 
 pumping vehicle to alternative water injecting line, injecting fresh 
 water to spent fuel pool of Unit 4 was started (hydrazine was also 
 injected from 1:48 pm and completed at 3:18 pm on same day). At 3:44 pm 
 on June 16, the injection was completed. 
·On June 16, spraying inhibitor for about 6,660 m2 was implemented by 
 worker on the road around the former administration office building etc.  
 
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.
