Since March 11, 2011, severe accidents occurred at Fukushima Daiichi Nuclear Power Station, the government of Japan and Tokyo Electric Power Company (TEPCO) and all Japan's companies have been worked on the remediation. The first meeting of "Government and TEPCO's Mid-to-Long Term Countermeasure Meeting" was held on December 16, 2011, and 19 research and development projects and Working team / Sub working team were launched. Japan Atomic Energy Agency; Fukushima Project Teams in Nuclear Fuel Cycle Laboratories and Nuclear Science Research Institute are belonging to the projects of "Fuel debris characterization", "Analysis of fuel debris" and "Treatment technology development of fuel debris". In the 2012 JFY, we carried out research and development on the "Fuel debris characterization" and "Treatment technology development of fuel debris", and obtained some results on the debris properties and debris treatment technologies.
