摘要: Disposed spent nuclear fuel can be seen as an artificial counterpart to natural uranium deposits. For investigating safe storage options of this material, its geochemical alterations are examined. Secondary phases which formed during leaching alteration UO2 surfaces were investigated with Raman microspectro-metry and characteristic vibrational spectra the materials recorded. U peroxide (UO4) was identified by comparison a studtite sample main phase 0-0 active vibration at 870 cm-1.
