It has been revealed that the head of the Fukushima Daiichi plant during its nuclear accident testified about flaws in the facility’s logistic supply system.
Masao Yoshida pointed to the problems in his testimony to a government-appointed investigative panel. He later died of illness, in July last year.
The plant lost power and needed many batteries to run after the massive earthquake and tsunami.
But the head office of the plant’s operator, Tokyo Electric Power Company, delivered batteries with insufficient voltage that were too large to be easily carried. Investigative reports say most of the batteries were not used.
Yoshida said the office seemed to have sent whatever batteries it could gather without informing the plant about their specifications. He said that forced plant workers to examine the batteries one by one.
Yoshida also referred to a stoppage of supplies of generators and other items to the plant after radiation levels rose around the site. Most supplies only reached a facility 50 kilometers from the plant.
Yoshida said he had to have workers fetch supplies while they were busy dealing with the accident. He suggested that the firm lacked an adequate system for transporting supplies amid high radiation levels.
The government plans to disclose Yoshida’s testimony next month. It has not been accessible to the public, as he did not want it released.
