Actions for environmental restoration of Fukushima

Okada, Takashi 

JAEA had initiated the Cabinet Office commissioned Decontamination Pilot Project, immediately after Fukushima Daiichi NPS accident. These results contributed to the decontamination-related guidelines that the government established. According to these guidelines, the government and municipalities carried out environmental decontamination. The removal soil and the waste occurring by cleanup in Fukushima are estimated to be 16M-22M m. The government decided to keep these huge the removal soil and the waste intensively in the Interim Storage Facility. In addition, by 30 years, it decided to let these disposal complete out of Fukushima. A key to realize disposal out of Fukushima is to reduce quantity of disposal. The government decided to utilize the removal soil for relatively low concentration of radioactivity based on a safe evaluation in public projects where its reuse will be limited to structural foundations.
