Japan Atomic Energy Agency has reorganized past R&Ds and launched PSi project (PSi: Proton accelerator-driven Subcritical virtual system) for R&D on ADS (Accelerator-Driven System). The PSi project aims efficient R&D toward industrialization of partitioning and transmutation by Accelerator-Driven System (ADS) by constructing "virtual" ADS on computer. The project is planed for around 10 years and final goal is to be ready for final design and approval application of demo-scale ADS. The project consists of four R&D fields: reactor physics and nuclear data, ADS plant and safety, lead-bismuth eutectic (LBE) and material, and, accelerator. Each field includes computation code for efficient engineering design, construction of model assembled in the code, and experiments to verify and validate the model. The experiment is not large-scale mock-up but small one using existing facility in Japan and the world.
