Alfven eigenmodes driven by positive energy gradients in the alpha particle distribution have been observed in JET deuterium-tritium hybrid JET pulses heated only by neutral beam injection. Coherent low frequency magnetic fluctuations were detected in D-T pulses, but were absent in pure D reference pulses, indicating that the modes were destabil…
Hydride precipitation and reorientation has the potential to embrittle zirconium alloys. This study aims to better understand the influence of the Zr microstructure on hydride precipitation and reorientation. Specifically, the crystallography, phase stability and morphology of hydride precipitation was correlated to microstructural variations due t…
