The government ordered Tokyo Electric Power Co. on Thursday to reinvestigate 199 cases of data falsification and other irregularities at its nuclear plants in connection with state inspections.
Japan's largest power utility will have to identify the causes of the irregularities and compile preventive measures by March 1 under the order based on related laws, the Nuclear and Industrial Safety Agency said.
The order follows Tepco's admission Wednesday that it falsified data at its nuclear power plants to cover up problems during government inspections on 199 occasions between 1977 and 2002.
