Abstract. 2014 The energy of the first plasmon loss peak has been determined for the ~-Zr hydride phase in pure Zr. The peak energy is sufficiently different from that of the 03B4-hydride to permit EELS "fingerprinting " with ease using a parallel EELS system, but with greater difficulty using serial EELS, because of drift associated with the slower collection rates. Experiments on Zr-2.5Nb alloys showed that the hydride phases can also be distinguished using EELS, facilitating the analysis of hydride pre-cipitates and blisters in nuclear reactor pressure tubes.
