Solidifying and solid cryogens in steady shear are of fundamental importance to the fueling of fusion energy reactors. We present steady-state measurements of the dynamic shear stress, thermal-conductivity, and heat transfer during flow of solid hydrogen, deuterium, and neon in a Couette-type viscometer cell. The measurements span a range of shear rates and temperatures from the onset of solidification to sub-cooled solid states. Normalization of the shear stress with parameters of the Lennard-Jones 6-12 potential indicates a favorable prediction of tritium properties using the quantum law of corresponding states.
