Solid breeder and beryllium materials database

The databases for solid breeder ceramics (Li{sub 2}O, Li{sub 4}SiO{sub 4}, Li{sub 2}ZrO{sub 3}, and LiAlO{sub 2}) and beryllium multiplier material were critically reviewed and evaluated as part of the ITER/CDA design effort (1988-1990). The results have been documented in a detailed technical report. Emphasis was placed on the physical, thermal, mechanical, chemical stability/compatibility, tritium retention and release, and radiation stability properties which are needed to assess the performance of these materials in a fusion reactor environment. Data-based materials properties correlations were selected for use in design analysis. Ranges for input parameters (e.g., temperature, porosity, etc.) were established. Also, areas for future research and development in blanket materials technology were highlighted and prioritized. In the current paper, the performance of these five blanket materials are compared graphically, based on the correlations presented in the ITER report. New data which have become available over the past several years are reviewed and evaluated. The impact of these new data on blanket materials performance is discussed, as well as additional experiments which would strengthen the database for these materials.
