ABSTRACT
Beryllium, in its pebble form, has been proposed in
various blanket concepts to serve different purposes.
Thermal property data for such a heterogeneous packed
bed is needed, particularly data on the impact of
compression forces on its magnitude and consequent
temperature profile. The objectives of this work are to
obtain and quantify experimental data on the effective
thermal conductivity of a Be-He packed bed, on the
interface heat conductance between Be and SiC, and on
the effects of externally applied pressure on these
effective thermal properties. The effective thermal
conductivity of a Be-He pebble bed increases as the bed
mean temperature increases. The values of effective
thermal conductivity vary from 2.15 to 3.00 W/m.K for
