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 nuclear power stations (Fukushima Daiichi and Fukushima Daini).

* The updates are underlined.

[Fukushima Daiichi Nuclear Power Station]
･ Unit 1 to 4: Abolishment (April 19, 2012)
･ Unit 5 to 6: Outage due to regular inspections before the earthquake

-At 8:26 AM on June 10, we started transferring the accumulated water from Unit 3 Turbine Building basement to the Central Radioactive Waste Treatment Facility (Miscellaneous Solid Waste Volume Reduction Treatment Building [High Temperature Incinerator Building]). We stopped transferring at 9:50 AM on June 23.

-At 10:05 AM on June 23, a worker from cooperative company who worked outside the NPS has injured his left heel by slipping and falling, when he got down from back of the truck. He was taken to Unit 5 and 6 emergency medical office. As a result of the clinical examination, he could not walk and was suspected fracture on his left heel. After been taken to J-village, he was transported to Iwaki Kyoritsu General Hospital on the ambulance. As a result of clinical examination by the doctor of the hospital, he was judged “left heel fracture”, and that it requires 3 months for recovery. We confirmed that no radioactive material was found to be attached to the worker’s body.

-At 10:15 AM on June 23, a worker of TEPCO confirmed that the water was flooding from the polyethylene tank which received the high pressure pump ground water for water treatment at the Desalination System 2 (Reverse Osmosis Membrane). The amount of flooded water was approx. 6.6 little. The water stayed in the dam, and did not leak outside the building. At 10:30 AM on the same day, we stopped the Desalination System 2 (Reverse Osmosis Membrane), and separated the pump. The dose measurement of the atmosphere and the dose at the surface near the puddle were below 0.1mSv/h as of  both gamma ray and beta ray. The results of the flooded water sampling was as follows.

 I-131: below the detection limit (detection limit : 7.0 x 10^-1 Bq/cm³)
 Cs-134: 2.6 x 10⁰ Bq/cm³
 Cs-137: 3.9 x 10⁰ Bq/cm³
 All β: 9.0 x 10⁴ Bq/cm³
