At the Kashiwazaki-Kariwa Nuclear Power Station of Tokyo Electric Power Company, in 2015, a worker of a partner company mistakenly used the ID card of the father of the same company and entered an area where identity verification is required for measures against terrorism. I understand.
At the Kashiwazaki-Kariwa Nuclear Power Plant, there were a series of problems related to anti-terrorism measures such as employees illegally entering the central control room last year, and TEPCO is proceeding with analysis of the causes, including past cases, of how the management system was.
According to TEPCO, in August 2015, six years ago, when a worker of a partner company entered a "peripheral protected area" where identity verification was required for anti-terrorism measures, the ID card of the father working at the same company was mistaken. I presented it to the guards and entered the area as it was.
Later, an alarm sounded at a mechanical gate in a more tightly controlled "protected area" that was identified as his father's.
Last September, the Kashiwazaki-Kariwa Nuclear Power Plant was punished by the Nuclear Regulatory Commission for serious deficiencies in anti-terrorism measures due to a series of problems such as employees illegally entering the central control room.
TEPCO said, "The guards seemed to feel uncomfortable with the photo, but the workers also misunderstood it as their own, and as a result, it seems that they were allowed to enter the area. We are currently conducting a fundamental cause analysis, such as how the management system for entering important areas has been going back to the past, and we would like to use it for recurrence prevention measures in the future.
