The Quarter Port Submodule (QPS) was proposed as
a Solid Breeder (SB) Test Blanket Module under the US
program of the SB blankets. The QPS features layer
configuration, in its left half, where the SB pebble beds
are parallel to the first wall and edge-on configuration, in
its right half, where the SB pebble beds are perpendicular
to the first wall. The objective of this study is to
investigate: (i) the QPS thermal profile under steady state
conditions and ITER transient loads, and (ii) the impact
of the interface conductance h on the QPS thermal
profile. In addition the effect of lack of contact, at the SB
pebbles/structure interface, on the QPS thermal profile is
presented. The results of the steady state cases showed
that h has a significant impact on the QPS thermal
profile. The QPS transient analysis provided results on:
(i) QPS thermal profile under a pulse length of 400s, (ii)
