NAGOYA – More than 100 errors have been found in safety inspection reports on a nuclear power plant run by Chubu Electric Power Co., but the utility has denied any irregularities.
The errors, which include wrong numbers and reference codes related to plant operations, were found in the records of about 2,500 safety checks that Chubu Electric conducted over the last 10 years on four reactors at the Hamaoka nuclear station in Shizuoka Prefecture, a company official said Monday.
The official, who asked not to be named, described the errors as “clerical” and said they will be reported soon to the Nuclear and Industrial Safety Agency of the Ministry of Economy, Trade and Industry.
Since September, Chubu Electric has cross-checked its records with those kept by a subcontractor engaged in safety inspections on the plant.
The Chubu Electric official said the errors, 16 of which were made public in an interim report released last fall, occurred when reprinting the subcontractor’s data in the company’s own books.
“Our employees were present during the work to compile the documents concerned. The subcontractor is responsible for most of the mistakes, but none are critical,” the official said, denying any falsification or concealment of data.
In a time of both misinformation and too much information, quality journalism is more crucial than ever.
