This report provides a summary of the irradiation vehicle design and thermal analysis of absorber material specimens planned for irradiation in the flux trap of the High Flux Isotope Reactor (HFIR). Four different absorber materials will be inserted in the same capsule: hafnium carbide without additive (HfC), hafnium carbide with molybdenum silicide additive (HfC + MoSi₂), samarium hafnate (Sm₂HfO₅), and europium hafnate (Eu₂HfO₅). The capsule design,with target temperatures of 300°C,will accommodate twelve specimens. Two capsules are planned to be built and irradiated to two different neutron fluence levels.
