Internal Investigative Report on the Fukushima Nuclear Accident
The Tokyo Electric Power Company recognizes ourselves as the main party involved in the nuclear accident triggered by the Tohoku-Chihou-Taiheiyo-Oki Earthquake on March 11, 2011. We have established the "Fukushima Nuclear Accident Investigation Committee" and "Nuclear Safety and Quality Assurance Meeting Accident Investigation Verification Committee" comprised of external experts, and have been engaging in a thorough investigation and verification of the accident. An interim report that summarizes the results of our investigation and verification efforts was released on June 20, 2012 entitled the "Fukushima Nuclear Accidents Investigation Report".
With the release of this report, we are once again made keenly aware of our responsibility for the accident and are determined to engage in business operations with safety as the top priority in order to prevent future recurrence. At the same time, we will continue thoroughly implementing our mid to long-term measures toward decommissioning of the reactors at Fukushima Daiichi Nuclear Power Station.
