 R&Ds on fabrication process of breeding functional materials, tritium breeders and neutron multipliers for JA DEMO applications have been done so far. Through many trials and errors, Li added Li2TiO3 with Li2ZrO3 solid solution (LTZO) as 1 mm-pebble have been successfully fabricated by an emulsion process. Additionally, we optimized the fabrication process to create not only 1 mm-pebbles but also small-sized pebbles with 0.3 mm in diameter. Regarding R&Ds on beryllides, several characterizations of beryllide blocks, including mechanical properties, reactivity to water vapor, swelling properties, hydrogen retention, compatibility with other materials, have been carried out, indicating that beryllide blocks can be adopted.
 In this study, current R&Ds on advanced breeding functional materials in JA DEMO activities will be given. Additionally, the refinement and recycling process of these materials established by the QST will be addressed by applying the innovative refining process with chemical reaction and microwave heating. |
