REBCO coated conductor tapes are a highly attractive option for magnet materials in future tokamak fusion power plants. However, the threat of intense neutron and gamma radiation, plus AC loss power dissipation during magnet coil ramping, raises concerns around REBCO magnet coil lifetimes. Irradiation-induced flux creep, or AC loss, has been ide…

In the hot metal forming processes, materials deform viscoplastically and the microstructure of materials changes dynamically, and constitutive equations used to characterize the material flow and microstructure evolution during the deformation can be complicated. Although different types of constitutive equations have been proposed by many researc…

This paper describes a novel automatic solution for toolchanging operations using dexterous teleoperated robots in a nuclear glovebox. This solution can identify and locate tools in the nuclear glovebox by visually tracking augmented reality (AR) tags online at a low computational cost. The solution is designed in a modular manner taking into accou…

The small punch test (SPT) has been widely used to evaluate the mechanical properties of materials for the nuclear industry due to its advantage of requiring minimal sample volumes. In this paper, the correlation between SPT and uniaxial tensile testing (UTT) is investigated for three materials used in the plasma-facing components of fusion reactor…
