  The fabrication of bulk delta-phase Zirconium Hydride ($\delta$-ZrH) using
Zircaloy-4 as a precursor is herein reported. Characterization using
electron-microscopy methods indicate that the fabricated material is of a
single-phase. Sn-rich segregation zones have been observed to form as a direct
result of the hydriding process. These findings experimentally validate
previous \textit{ab initio} calculations on the influence H incorporation in
Zircaloy-4 constitutional elements such as Sn, Fe and Cr. The effect of
hydriding and Sn segregation on pre-existing Zr(Fe,Cr)$_{2}$ Laves phases is
also evaluated. Major implications on the development of moderators for use in
microreactors within the nuclear industry are discussed.
