Virus leaks maintenance data on Japanese nuclear power plants
Maintenance data on nuclear power plants were leaked and shown on the Internet after a computer virus attacked a personal computer of an employee of Mitsubishi Electric Corp.'s subsidiary in charge of plant inspections and maintenance, it was learned Thursday.
Data equivalent to 31 floppy disks, including a draft report of power plant inspections, a repair manual, name lists of inspection workers and photographs of the inside of the plants, were leaked from the employee's privately owned PC.
The plants included Tomari Nuclear Power Station of Hokkaido Electric Power Co., Sendai Nuclear Power Station of Kyushu Electric Power Co. and Mihama Nuclear Power Plant of Kansai Electric Power Co.
As much of the information was confidential, the problem is expected to stir controversy over the security of information on nuclear power plants and other related facilities, nuclear experts said.
