Description

Spin-phonon interactions lead to low @@ of UO2 (and behave like a defect), and this has implications for nuclear fuel performace. The inability to capture spin-phonon scattering leads to inherent errors. The interplay between magnetism and structural asymmetry in UO2 displays rich physics. Grain boundary structure plays a role which must be taken into account.
