One of the techniques of minor actinides transmutation is to recycle these nuclides into fission reactors. Two concepts of a minor actinides burner reactor with very hard neutron energy spectrum as well as very high neutronjlux me discussed. The fuel cycle facilities for these burner reactors am assessed to discuss the technical feasibili~ of these reactors. Transmutation of minor actinide in b...

The short-range structures of molten alkali actinide fluoride salts were studied using in situ EXAFS combined with molecular dynamics simulations.

We have calculated r-process nucleosynthesis in a new supernova model, which is driven by acoustic power generated in the inner core. In our results, plenty of actinide and the third peak elements are generated. However, light r-process elements around the first and second peak are overproduced. Our present results indicate that further studies of the r-process in this model are desirable.

A TREN-G1-DGA dendrimer was evaluated for the extraction of different actinide and Eu 3+ ions in C 4 mim·NTf 2 with unusual trends.

The first 3D actinide polyrotaxane framework (named IHEP-URCP-2) has been obtained based on windmill-like six-connected high-nuclear oligomeric uranyl nodes under hydrothermal conditions. Notably, the in situ formed pseudorotaxane ligand simultaneously plays dual roles of both a bulky pseudorotaxane linker and a supramolecular guest.

Several questions of importance in the study of lanthanide and actinide coordination compounds are reviewed. There is considerable evidence that in aqueous solution the primary coordination number is nine for the ions La(ni) through Nd(m) and eight for the ions heavier than Gd(m). While it seems that some degree of covalency exists in the metal—ligand bonding a model of electrostatic bonding se...

Collisions of actinide nuclei form, during very short times of few zs (10−21 s), the heaviest ensembles of interacting nucleons available on Earth. Such collisions are used to produce super-strong electric f elds by the huge number of interacting protons to test spontaneous positron-electron pair emission (vacuum decay) predicted by the quantum electrodynamics (QED) theory. Multi-nucleon transf...

At present, designing novel ligands for efficient actinide extraction in spent nuclear fuel reprocessing is extremely challenging due to the complicated chemical behaviors of actinides, the similar chemical properties of minor actinides (MA) and lanthanides, and the vulnerability of organic ligands in acidic radioactive solutions. In this work, a quantum chemical study on Am(III), Cm(III) and E...
