During the Fukushima nuclear accident, a huge amounts of radioactive materials leaked out of the reactor building shell and polluted a large surrounding area. Furthermore, the secondary pollutants produced during the subsequent processing are still active. Therefore, the radioactive wastes in the Fukushima nuclear accident have the characteristics of huge amounts and wide range. It remians a serious challenge to the disposal measures. This paper introduces the environmental pollution after the accident, especially in the site of Fukushima nuclear power plant. The classification, characteristics and disposal measures of the radioactive wastes are analyzed, respectively. Suggestions on disposal measures of radioactive wastes and the inspiration on China's nuclear power development are summarized.
