Development of fabrication technologies for advanced breeding functional materials For DEMO reactors

Development of the Water Cooled Ceramic Breeder Test Blanket Module in Japan

“…However, the Li addition by solid state reaction was found to be difficult. In the recent study, we have developed a new process [21]. Li 2 TiO 3 with added Li was synthesized from proportionally mixed LiOH·H 2 O and H 2 TiO 3 with a Li/Ti ratio of >2.0.…”

“…Transportation properties of multi-component hydrogen isotopes including tritium were investigated experimentally [22]. Ceramic proton conductor membrane used in this work was SrCe 0.95 Yb 0.05 O 3−␣ (SCO) made by TYK Co. HT-H 2 mixture (H/T ratio: ∼12,000) balanced with He was supplied to the hydrogen pump, that was kept at 873 K and applied the voltage between 0 and 1000 mV.…”

Pebble fabrication and tritium release properties of an advanced tritium breeder

“…A technique for the fabrication of Li 2+x TiO 3+y pebbles using the emulsion method has been reported [9,10]. The emulsion method is one of the candidate methods for mass pebble production.…”

Optimization of sintering conditions of advanced tritium breeder pebbles fabricated by the emulsion method

“…Pebble fabrication using the emulsion method is one of the promising techniques for the mass production of advanced tritium breeder pebbles, and development of the emulsion method as a fabrication technique for Li 2+x TiO 3+y pebbles has been pursued [10]. In a previous study, sintered Li 2+x TiO 3+y pebbles of a 1.4 mm diameter were fabricated, and the average grain size on the surfaces and cross sections was determined to be <5 and 5-10 m, respectively.…”
