Press Release (Jun 11,2011)
Status of TEPCO's Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake (as of 4:00 PM, June 11)
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) -We installed local exhausters and started to operate them at 12:42 pm on June 11 in order to improve the working environment inside Reactor Building of Unit 2. -At 3:30 pm on June 11, we started to transfer accumulated water in the basement of Unit 3 turbine building to Centralized Radiation Waste Treatment Facility (Process Main Building). -At 10:00 am on June 11, we resumed transferring the accumulated water in the basement of Unit 6 turbine building to temporary tanks. At 3:00 pm on the same day, we finished transfer. -On June 11, dust inhibitor is being sprayed to the area including the observation point.
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 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 to save electricity.
