The pH evolution and corresponding changes in the UV–Vis–NIR absorption spectra of
oxygenated neptunium (NpO2+ and NpO22+) and uranyl ions (UO22+) in nitric acid are …

A hybrid route combining internal gelation and a single-step infiltration was investigated to
prepare U 1-y Nd y O 2-x sintered microspheres as a surrogate for U 1-y Am y O 2-x …

Abstract The International Atomic Energy Agency implements safeguard measures to verify
the compliance of Member States to their international legal obligations using nuclear …

An innovative, dust-free method for producing (U, Am) O 2-x targets without the generation of
Am-contaminated liquid waste has been successfully demonstrated in the Fuel Materials …

The sol-gel route via internal gelation was applied for the production of Nd-and Ce-doped
uranium dioxide microspheres. Trivalent and tetravalent Ce precursors were used and the …

Internal gelation of aqueous mixtures of metal (M= Ln, An) nitrate with Uranyl Nitrate is
generally assumed to yield cation homogeneity and a fluorite type single phase U 1-z M z O …

Process conditions for the fabrication of porous uranium oxide microspheres prepared via
internal gelation were assessed. To improve conditions for the application of infiltration …

The crystal structure of ammonium polyuranates x UO 3· y NH 3· z H 2 O has been
investigated. Powder X-ray diffraction (PXRD) has been employed to define single-phase …

Microparticulate reference materials with well-defined properties are needed by the
International Atomic Energy Agency (IAEA) to consolidate a sustainable quality control …

A new and efficient low-temperature chlorination-roasting–acid-leaching uranium process
was proposed to solve the problems of low leaching efficiency, since the leaching residue …
