Effect of surface water on tritium release behavior from Li2TiO3

Release behavior of water vapor and mass loss from lithium titanate

“…4. The capacity of chemical adsorbed water per gram of Li 2 TiO 3 with added Li by JAEA is similar to that of Li 2 TiO 3 made by NFI (Nuclear Fuel Industries) [8] while the temperature dependence is a little different. The surface area [m 2 /g] estimated from the grain size of Li 2 TiO 3 by JAEA, 0.0583 m 2 /g is much smaller than that of Li 2 TiO 3 by NFI, 0.350 m 2 /g.…”

“…5. The capacity of water formation per gram of Li 2 TiO 3 with added Li from JAEA is 4.5 times larger than that of Li 2 TiO 3 by NFI [8].…”

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

“…In accordance with considerations of the tritium release characteristics and the packing factor of the blanket, it has been determined that the optimum pebble diameter and grain size after sintering are 1 mm and <5 m [11], respectively. Therefore, the present study has sought to optimize the sintering conditions to obtain these target values.…”

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

“…Considering the tritium release characteristics and the packing factor of the blanket, the desired pebble diameter and grain size after sintering were 1 mm and <5 m [21], respectively. Therefore, the next step was to optimize the granulation conditions to reach these target values.…”
