The 22nd International Workshop on the Ceramic Breeder Blanket Interactions (CBBI-22) is the biannual event that brings together the community of ceramic breeder scientists and technologists for nuclear fusion. Date: 6-8th October, 2025 Venue: Obaku plaza, Kyoto University Uji campus, Kyoto, Japan Website: https://indico.nifs.ac.jp/e/CBBI22 CBBI is the forum for the researchers, engineers and technologists, involved in the development of the fusion ceramic breeding blanket concept, to exchange the latest progress in the design, fabrication, modeling, materials, isotope separation, and tritium breeding/extraction. Organized under the auspices of the IEA Implementing Agreement on the Nuclear Technology of Fusion Reactors, and in conjunction with the International Conference on Fusion Materials (ICFRM-22) in Shizuoka, the CBBI-22 will be held from 6th to 8th October 2025, at Obaku plaza, Kyoto University Uji campus, in the beautiful and historical city of Kyoto, Japan. The CBBI-22 was held jointly with The 17th International Workshop on Beryllium Technology (BeWS), having CBBI/BeWS joint sessions on 6-7th October 2025. This workshop should be the stage to show updates of TBMs for ITER and a debate forum for its exploitation towards DEMO and Fusion Pilot Plant (FPP) by the private sector.
