The development of breeder fabrication technology has been exclusively devoted to manufacturing processes for pebbles, since most solid breeder blanket designs are based on pebble-beds and TheLithium based ceramics is one of the most important components of a fusion reactor because it directly involvesboth energy extraction and tritium production, both of which are critical to fusion power and have a long been recognized as promising tritium-breeding materials for Test Blanket Modules (TBM) of the International Thermonuclear Experimental Reactor (ITER) The world-wide efforts on ceramic breeder materials in the last two years concerned Li2O, Li4SiO4, Li2TiO3 and Li2ZrO3, and Li2TiO3. The lithium-basedceramics have shown good irradiation behavior and excellent tritium release characteristics. Individual materialsperformance will depend upon the actual application, namely, pebble bed versus pellet concept, higher versus lower cooling temperature, etc. There are different methods: extrusion/spheronization, melting/spraying, gelcasting, wet method.Keywords

The overall performance of the grinding wheel is difficult to analyze, as it is a compilation of individual abrasive grit contributions. The single grit scratch test is useful to investigate the effect of the individual grit effect on the work material. A vacuum-brazed diamond dresser is developed for the single grit scratch experiment. Partially stabilized zirconia is used as work material to study the mechanics of material removal and mode of grit failure. The experiments were performed in dry conditions by varying the wheel speed, table feed, and depth of cut. The grit failure mechanism has been analyzed using a scanning electron microscope image and correlated with the induced force during the scratch test. The results show that the diamond microcracking was observed after 370 mm of grinding scratch marks. And the maximum tangential and normal force withstand by the diamond grit is 13.09 N and 19.65N, respectively.Keywords
