Long-term thermal stability of biphasic Li4SiO4-Li2TiO3 EU reference tritium breeder ceramics enriched in Li-6

Nuclear Materials and Energy
The long-term thermal stability of Advanced Ceramic Breeder (ACB) pebbles was investigated in an annealing experiment at 700 and 900 °C in He + 0.1 vol% H2 gas atmosphere for up to 60 days. Four batches of biphasic ACB pebbles, consisting of Li4SiO4 with

Paramagnetic radiation-induced defect centres and their correlation with the optical properties of irradiated advanced ceramic breeder pebbles

Nuclear Materials and Energy
Advanced ceramic breeder (ACB) pebbles, primarily composed of lithium orthosilicate (Li4SiO4) with lithium metatitanate (Li2TiO3) as a second phase, are currently under development and testing as the European Union’s reference material for tritium ...

Reaction kinetics of Li4SiO4 and Li4Ti5O12 in biphasic breeder ceramics after lithium burn-up

Nuclear Materials and Energy
Advanced ceramic breeder (ACB) pebbles consisting of the two phases Li4SiO4 and Li2TiO3 serve as the EU reference tritium breeding material. In the present study, the phase stability with regard to a lithium-burn-up is investigated.

Tritium Breeding Ceramics for Nuclear Fusion [PDF]

Tritium and deuterium are widely considered as fuel for fusion power plants. While deuterium is quite abundant in nature, tritium needs to be “bred” from lithium in a neutron reaction.
