The alternative approach focuses less on an overall
actinide balance and more on addressing IAEA goals: timely detection of diversion or undeclared production or processing of nuclear material.

In Figures (7,8) we show the results of our calculations for the ground state bands of the selected lanthanides and
actinides isotopes.
Strontium and the
actinides are removed fairly rapidly despite the high salt concentration.
In the end, though, there's little doubt that Seaborg's table of rows and turrets, with the lanthanides and
actinides like moats along the bottom, will dominate chemistry classes for generations to come.
plutonium and other
actinides (1) in the spent fuel pose a long-term
Synergistic solvent extraction of trivalent lanthanides and
actinides by mixtures of 1-phenyl-3-methyl4-benzoyl-5-pyrazolone and neutral oxodonors.
The design criteria include the minimisation of waste and better management of natural resources, while four of the six selected systems are 'fast reactors' associated with a closed cycle to burn long-lived
actinides. Fast reactors with depleted uranium will produce new fissile material."
These materials, formed during irradiation of fuel in the reactors, are collectively known as the minor
actinides, to distinguish them from the larger quantities of uranium and plutonium also present in the fuel.
