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 progress status of roadmap considering 
the current situation, on July 19. Accomplishment of the Step1 target 
"Radiation dose is in steady decline" has been confirmed. On October 17, 
we updated the further progress. 
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.

* The underlined parts are the updates from the previous press release.

[Nuclear Power Station]

· Fukushima Daiichi Nuclear Power Station: Unit 1 to 3: shut down due to 
  the earthquake
    (Units 4 to 6: outage due to regular inspections)

- At 10:00 am October 20, transportation of accumulated water from unit 3 
  turbine building basement to Centralized Radiation Waste Treatment 
  Facility (Miscellaneous Solid Waste Volume Reduction Treatment Building 
  [High Temperature Incinerator Building]) was started. At 9:16 am on
  October 28, we stopped the transfer.

- At 9:30 am on October 28, due to the additional installment of control
  valve of Unit 1 water injection line to improve controllability of water
  injection, we switched water injection line into the reactor of Unit 1
  and Unit 2 from normal line to emergency line. As the installment work
  was finished, at 1:30 pm on the same day, we switched water injection
  line from emergency line to normal line. At 2:00 pm on the same day,
  accompanied by the switching of injection line, we adjusted water
  injection rate from feed water system approx. 3.9㎥/h for Unit 1. We
  also adjusted water injection rate from feed water system approx.
  3.0㎥/h and from core spraying system approx. 7.0 ㎥/h for Unit 2.

- At 10:00 am on October 28, we started transferring low-level accumulated
  water to Mega Float from a temporary tank where we had transferred from
  the turbine building of Unit 6.

- With regards to accumulated water of Unit 2, for the purpose of changing
  transfer route, at 9:32 am on October 28, we stopped transfer of
  accumulated water from underground of turbine building of Unit 2 to
  centralized radiation waste treatment facility (process main building).
  At 9:54 on the same day, we changed transfer route and started transfer
  of accumulated water from underground of turbine building of Unit 2 to
  centralized radiation waste treatment facility (Miscellaneous Solid
  Waste Volume Reduction Treatment Building)[ High Temperature Incinerator
  Building]).

- At around 11:30 am on October 24, we observed the water leakage (about 
  20 litters) from the axis seal region of the law water pump (for 2-1 
  skids use) which was a constitution apparatus of the Water Desalination 
  Facility (RO membrane unit) 2 of the water treatment system and we 
  stopped the facility. Afterward, the water leakage was confirmed to be 
  stopped. At 2:30 pm on the same day, we stopped the line connecting to 
  the water pump and started other water desalinations. At 4:20 pm, the 
  rated flow reached 50㎥/h. Thereafter, on October 27 and 28, we
  conducted replacement work of relevant pump.

- At 12:53 pm on October 28, we started up the exhaust fan of gas
  management system of primary containment vessel in the reactor building
  of Unit 2 and commenced commissioning.

- At around 2:20 pm on October 28, one of TEPCO's employee conducting
  document check at administrative building has removed face mask when
  that employee felt sick and vomit, We plan to conduct check the intake
  by whole body counter. We have confirmed there was no contamination on
  the face.

· Fukushima Daini Nuclear Power Station: 
    Units 1 to 4: shutdown due to the earthquake

· Kashiwazaki Kariwa Nuclear Power Station:
    Units 5, 6: under normal operation
    (Units 1 to 4 and 7: outage due to regular inspections)

[Thermal Power Station]
- Power supply has returned to normal and facilities damaged by the 
  earthquake are now being handled in a timely manner.

[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.

[Impacts on Power Supply and Demand Balance]
Thanks to our all customer's energy-saving efforts, we could successfully 
maintain an even supply-demand balance in this summer. We express our 
deepest appreciation to the efforts.

While we will continue to exert maximum effort to stabilize the supply-
demand balance, we kindly request your continued efforts in keeping 
electricity consumption within reasonable levels.
