Press Release (Mar 04, 2013)Status of TEPCO's Nuclear Power Stations after the Tohoku-Chihou-Taiheiyou-Oki Earthquake(Daily Report as of 3:00 PM, March 4)

 

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 8:55 AM on March 4, the nitrogen supply equipment (nitrogen gas separator on the hill) on standby (operable) has been excluded from standby state in order to perform a full-scale inspection*. During the inspection, the two regular nitrogen gas separators will be in operation to continue nitrogen injection into Units 1-3 RPV, etc.
*The facility management policy based on Chapter 12 of the technical specification for the nuclear reactor facility "Policy on the Mid-term Security" stipulates "operational requirements" and "necessary measures to be implemented in the case that the operational requirements are not fulfilled" (When the operational requirements are not fulfilled, the required measures must be implemented). In this case, the nitrogen gas separator on the hill was excluded from standby state intentionally for maintenance from 8:55 AM on March 4 (transition out of the scope of operational requirements).

· Unit 1 to 4: Shutdown due to the earthquake.

* Revised past progress
