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, 2011, we have compiled the roadmap towards restoration from the accident and on July 19 we accomplished the Step1 target "Radiation dose is in steady decline". Then on December 16 we confirmed the accomplishment of the Step 2 target "Release of radioactive materials is under control and radiation doses are being significantly held down".
In addition, on December 21, 2011, we have compiled the "Mid-to-long-Term Roadmap toward the Decommissioning of Fukushima Daiichi Nuclear Power Units 1-4, TEPCO".
In addition to the maintenance of the plant's stable condition, we will implement Mid-to-Long Term countermeasures towards the decommissioning of Fukushima Daiichi Nuclear Power Units 1-4 to enable evacuees to return to their homes as soon as possible and reduce the anxiety of the people in Fukushima and the whole nation as soon as possible.

Below is the status of TEPCO's major facilities.

* The updates are underlined.

[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 before the earthquake)

* At 9:37 am on March 20, we started transferring the accumulated water from the basement of Turbine building of Unit 1 to the basement of Turbine building of Unit 2. At 9:48 am on March 21 we finished this process.
* At 9:46 am on March 21, 2012, we stopped the cooling of the Spent Fuel Pool of Unit 4 in order to investigate the status of the pool. At 12:01 pm on the same day the inspection finished, and the cooling process was restarted (Temperature of the pool at the time of the operation stoppage: approx. 28.0°C, water temperature at the time of restart: approx. 28.0°C).
* At 8:30 am of March 21, we temporarily stopped the 2nd Cesium adsorption apparatus in order to implement reverse washing of the filter. At 11:48 am on the same day we reactivated the apparatus, and at 12:05 pm it reached its regular flow rate (approx. 42m³/h)
* At around 11:20 am on March 21, When workers of TEPCO's partner company were doing welding operation of plumbing for fire extinguish equipment near No. 3 light oil tank (outdoor type) of Fukushima Daiichi Nuclear Power Station Unit 5 and 6, it was confirmed by the workers that lawn of approx. 3m x 3m was burned due to fire sparks by the welding operation. At 11:25 am, we confirmed that the workers had extinguished the fire with water. At 12:13 pm, we reported this incident to the Namie city fire department, and at 1:13 pm they confirmed that this was a fire incident and the fire was out. No one was injured by this accident and this gives no impact on monitoring values of the surrounding area and cooling systems of the nuclear reactors and the spent fuel pools.

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

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

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

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

[Impacts on Transmission Facilities]
·Power supply has returned to normal and the facilities damaged by the earthquake are now being handled in a timely manner.

[Impacts on Power Supply and Demand Balance]
We expect to maintain stable power supply in March.
Daily supply and demand balance is announced at our "TEPCO Electricity Forecast".
