Rational treatment of a large volume of solid wastes resulting from the reactor dismantling is a key to success to carry out the decommissioning smoothly. From this viewpoint, the Japan Atomic Energy Research Institute (JAERI) has been conducting development of the recycling technology for metal waste and an investigation study on the rational recycling system for the dismantling wastes recycling. With respect to the development of the recycling technology, series of melting tests using non-contaminated metals, metal waste dismantled from JPDR or imitated waste using radioisotopes have been conducted. The basic characteristics of the radionuclides transport behavior during the melting have been understood. In the investigation study on the rational recycling system, a scenario of recycling the wastes was developed based on the amount of waste arising from decommissioning nuclear power plants, and necessary processing facilities were examined, and safety and economy of the process were evaluated.
