Photonuclear reactions of actinide and pre-actinide nuclei at intermediate energies

Strong correlations in actinide redox reactions.

Reduction-oxidation (redox) reactions of the redox couples An(VI)/An(V), An(V)/An(IV), and An(IV)/An(III), where An is an element in the family of early actinides (U, Np, and Pu), as well as Am(VI)/Am(V) and Am(V)/Am(III), are modeled by combining density functional theory with a generalized Anderson impurity model that accounts for the strong correlations between the 5f electrons. Diagonalizat...

Minor Actinide Transmutation

Actinide organometallic chemistry.

The stoichiometric and catalytic chemistry of metal-organic compounds having actinide-to-carbon bonds is in a stage of rapid growth. Chemical, structural, and bonding characteristics have been identified which differ in interesting and informative ways from those of d-block transition element compounds.

Actinide and Fission Product Partitioning

In Japan, R&D activities for partitioning and transmutation (P&T) have been promoted under the OMEGA programme for more than 15 years. These activities were reviewed by the Atomic Energy Commission in Japan in 2000. In accordance with the results of the review, three institutes, the Japan Atomic Energy Research Institute (JAERI), the Japan Nuclear Cycle Development Institute (JNC) and the Centr...

Magnetic Structure of Actinide Metals

In comparison to 3d or 4 f metals, magnetism in actinides remains poorly understood due to experimental complications and the exotic behavior of the 5 f states. In particular, plutonium metal is most especially vexing. Over the last five decades theories proposed the presence of either ordered or disordered local moments at low temperatures. However, experiments such as magnetic susceptibility,...
