Ternary fission of actinides probes the state nucleus at scission. Light clusters are produced in space and time very close to scission point. Within nonequilibrium statistical operator method, a generalized Gibbs distribution is constructed from information given by observed yields isotopes. Using this relevant operator, calculated taking excited states continuum correlations into account, acc...

The goal of this research is to develop electrochemically “switchable” separations that can be performed on-line with mass spectrometry for rapid elemental and isotopic analysis of actinides. The separation of uranium and plutonium, as well as other actinide elements, from complex solutions such as seawater, radioactive wastes and nuclear reprocessing solutions will benefit from a separation pr...

The effective use of pencil as a matrix for matrix-assisted laser desorption/ionisation (MALDI) for the study of actinides has previously been demonstrated (Black et al., Rapid Commun. Mass Spectrom. 2006; 20: 1053). Here, the scope of the types of molecules amenable to analysis by this method has been extended, establishing that approximately 90% of a library containing 50 diverse small molecu...

The Japan Atomic Energy Research Institute (JAERI) has proposed the concept of the transmutation of minor actinides (MA: Np, Am and Cm) with accelerator-driven systems (ADS), where MA nitride is adopted as a fuel material of a sub-critical core, because nitride fuel has the advantage of accommodating various MAs with a wide range of composition besides superior thermal and neutronic properties....

Abstract models have been developed to describe dissolution of Pu/Am/Cm after internal contamination by inhalation or wound, chelation of actinides by diethylene triamine penta acetic acid (DTPA) in different retention compartments and excretion of actinide-DTPA complexes. After coupling these models with those currently used for dose calculation, the modelling approach was assessed by fitting ...
