issue surfaced recently in international mining news covering Westfarmers's bid to take over Lynas Corp.
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.
Silver said not all REEs are mineralogically bound to actinides
. "You're failing to mention the ionic clays in Southern China that are not radioactive" that contain heavy REEs, he said.
Bond, "Crown ethers as actinide
extractants in acidic aqueous biphasic systems: partitioning behavior in solution and crystallographic analyses of the solid state," Journal of Alloys and Compounds, vol.
In Figures (7,8) we show the results of our calculations for the ground state bands of the selected lanthanides and actinides
Endomyocardial fibrosis (EMF) along with the root wilt disease of coconut is endemic to Kerala with its radioactive actinide
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.
