The use of lithium ceramic pebble beds has been
considered in many blanket designs for the fusion
reactors. Lithium ceramics have received a significant
interest as tritium breeders for the fusion blankets during
the last three decades. The thermal performance of the
lithium ceramic pebble beds plays a key role for the
fusion blankets. In order to study the heat transfer in the
blanket, the effective thermal conductivity of the lithium
ceramics pebble beds has to be well measured and
characterized. The data of effective thermal conductivity
of lithium ceramic pebble beds is important for the
blanket design. Several studies have been dedicated to
investigate the effective conductivity of the lithium
ceramics pebble beds. The objective of this work is to
review and compare the available data, presented by
various studies, of effective conductivity of lithium
