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 2:45 pm on June 29, we started injecting fresh water into the spent 
 fuel pool of Unit 3 using Fuel Pool Cooling and Filtering System, and 
 finished at 3:53 pm. 
-At 8:56 am on June 30, we started transferring the accumulated water from 
 the basement of the turbine building of Unit 3 to Centralized Radiation 
 Waste Treatment Facility (Process Building). 
-Since an alarm showing water leakage was sounded in the On-site Bunker 
 Building at 2:49 pm, the water treatment system was stopped again at 
 2:53 pm. Then, after swiping the leaked water and reset the alarm, we 
 restarted the operation at 6:45 pm. 
-At 6:54 pm on June 29, we stopped the accumulated water treatment system 
 due to the trouble occurred in the concerted operation of the cesium 
 adsorption instruments and the coagulation settling instruments. As a 
 result of investigation, we confirmed no abnormal issues on the 
 facilities and restarted the operation of the accumulated water treatment 
 system at 9:15 pm. 
-At approximately 5:40 on June 29, water leakage was confirmed at the 
 lower part of the closing flange of the storage tank for water 
 desalination (concentrated saltwater). We stopped the leakage and 
 installed a saucer at the lower part of the flange. 
-At 9:00 am on June 30, we stopped the water desalination system to treat 
 the concentrated saltwater in the storage tank of the system. 
-As a result of nuclide analyses, cesium-134 and cesium-137 were detected 
 from marine soil collected on June 28 (at 2 different points, approx. 
 3 km offshore of Fukushima Daiichi and Daini Nuclear Power Station).

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 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.
