Based on the experience of R&D results, such as the developing the prototype FBR, "MONJU," and related fuel cycle, the Japan Atomic Energy Agency carried out the joint study "Feasibility Study on Commercialized Fast Reactor Cycle Systems" with electric utilities, the Central Research Institute of Electric Power Industry and manufacturers. This study has two objectives, presenting "an appropriate concept of the commercial FBR cycle system" and "the R&D programs for commercialization", toward 2015. The "Combined system of sodium-cooled reactor (MOX fuel), advanced aqueous reprocessing and simplified pelletizing fuel fabrication" was selected, as the concept to be developed mainly from now, because it has the greatest potential conformity to the development requirements and has the high technical feasibility because it uses the accumulated results of past R&D, and international cooperation in this is possible.
