In recent years, scientists have progressively recognized the role of electronic structures in
the characterization of chemical properties for actinide containing materials. High-energy …

Research on actinide materials, both basic and applied, has been greatly advanced by the
general techniques available from high-intensity photon beams from x-ray synchrotron …

Recycling and burning minor actinides (MA, eg, americium, neptunium) in mixed-oxide
(MOX) nuclear fuel is a strategic option for fast reactor concepts of Generation IV, especially …

Mixed oxides of uranium and plutonium U 1-y Pu y O 2-x are currently studied as reference
fuel for Sodium-cooled Fast Reactors (SFRs). To predict the margin to fuel melting, an …

The early stage of microstructural evolution of ThO2, under krypton irradiation at 600, 800,
and 1000° C, was investigated using in situ transmission electron microscopy (TEM) …

Thermal conductivity and melting temperature of nuclear fuel are essential for analysing its
performance under irradiation, since they determine the fuel temperature profile and the …

We assess five empirical interatomic potentials in the approximation of rigid ions and pair
interactions for the (U 1− y, Pu y) O solid solution. The assessment compares available …

The analysis of individual micrometre-and submicrometre-sized particles collected by IAEA's
safeguards inspectors on swipe samples during in-field verification activities requires the …

Abstract The molecular Monte Carlo method, combined with the CRG interatomic potential,
is used for the first time to investigate stoichiometric mixed oxides U 1-y Pu y O 2 (with y in …

Some AX 2 binary compounds with the fluorite structure (space group F m 3 ̄ m) are well-
known examples of materials exhibiting transitions to ionic superconducting phases at high …
