X-ray absorption spectroscopy was applied to understand the speciation of elements relevant to the immobilisation and disposal of radioactive plutonium bearing wastes, utilizing Ce as a Pu surrogate. Ce L 3  XANES (X-ray Absorption Near Edge Structure) characterisation of a crystallised glass material produced by cold crucible plasma vitrification, at demonstration scale, evidenced incorporation as Ce 3+  within the glass phase, providing an important validation of laboratory scale studies. U and Ce L 3  XANES investigation of brannerite ceramics, U 0.9 Ce 0.1 Ti 2 O 6 , synthesized under oxidizing, neutral and reducing conditions, established the charge compensation mechanism as incorporation of Ce 3+  through formation of U 5+  and/or U 6+  In each of these examples, X-ray Absorption Spectroscopy has provided a pivotal understanding of element speciation in relation to the mechanism of incorporation within the host wasteform intended for geological disposal.
