Microstructure and density changes in Li2O during irradiation in BEATRIX-II, Phase I and II

Ceramic breeder materials: Status and needs

“…Ceramic integrity was maintained during irradiation (burnup 5Yo), although some structure changes and swelling occurred along with a very small loss of lithium [34,35]. For Li2Zr03 at this burnup level, tritium release was constant, with no indication that second phase formation degrades tritium release behavior.…”
