New synthesis method of advanced lithium titanate with Li4TiO4 additives for ITER-TBM

Release kinetics of tritium generated in lithium-enriched Li2+xTiO3 by thermal neutron irradiation

“…Therefore, it is planned in future fusion reactor to replace the lithium-depleted tritium breeding materials after certain periods of operations. To improve the life cycle of tritium breeding materials with respect to tritium generation property, the use of Li 2+x TiO 3 (x = 0.2, 0.4), which is the lithium-enriched Li 2 TiO 3 , is proposed recently [1][2][3].…”

Trial synthesis of Li2Be2O3 for high-functional tritium breeders

“…Among them, lithium titanate with excess Li (Li 2+x TiO 3+y ) and lithium orthosilicate (Li 4 SiO 4 ) are one of the most promising candidates for use as tritium breeder because of its good chemical and mechanical stabilities [2][3][4][5][6][7][8]. Currently, mixtures of tritium breeder and neutron multiplier (Be or Be 12 Ti) pebbles are being considered for increasing the tritium breeding ratio in breeding blankets.…”

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

“…However, the mass of Li 2 TiO 3 decreases with time in a hydrogen atmosphere because of Li evaporation and Li burn-up [5]. To prevent the reduction in mass at high temperatures, Li 2 TiO 3 with additional Li (Li 2+x TiO 3+y ) has been developed as an advanced tritium breeder [6][7][8]. Li 2+x TiO 3+y has higher stability at high temperatures in a reducing atmosphere.…”
