Abstract

Some example applications are presented, in which the peculiar Raman fingerprint of PuO₂ can be used for the detection of crystalline Pu⁴⁺ with cubic symmetry in an oxide environment in various host materials, like mixed oxide fuels, inert matrices and corium sub-systems. The PuO₂ Raman fingerprint was previously observed to consist of one main T_2g vibrational mode at 478 cm⁻¹ and two crystal electric field transition lines at 2130 cm⁻¹ and 2610 cm⁻¹. This particular use of Raman spectroscopy is promising for applications in nuclear waste management, safety and safeguard.
