Efforts on the Remediation toward Fukushima Restoration—Progress of Remediation and Lessons Learned—

Abstract

The accident of the Tokyo Electric Power Company’s Fukushima Dai-ichi Nuclear Power Plant widely effected an environmental contamination by radionuclides. No legal framework was prepared on remediation before the accident. Full-scale remediation started after putting the Act on Special Measured concerning the Handling of Pollution by Radioactive Materials in force on January, 2012. This paper describes activities before initiating a full-scale remediation, decontamination guideline, implementation of remediation and verification of results, and storage of contaminated materials arising from remediation with stating lessons learned.
