The Nuclear Regulation Authority said Friday it will scrutinize all simulations for the potential spread of radioactive materials from atomic power plants after it was found that the projections were riddled with mistakes.
"We would like to be sure that there will be no more errors, so the simulations are being thoroughly checked again," NRA spokesman Hideka Morimoto told a news conference.
More mistakes were announced Tuesday. The NRA said errors were found in wind direction data for Kyushu Electric Power Co.'s Genkai power plant in Saga Prefecture and Sendai plant in Kagoshima Prefecture.
