Figure 2 provides a plot of the concentrations of strontium, plutonium, neptunium and uranium versus time when a simulated waste solution is contacted with MST.
Christiansen, a geochemist at the University of Copenhagen who specializes in 'green rust', describes how it contains neptunium.
Minor actinides ~ 0.1 Important (MAs) primarily contributors to Neptunium (Np), long-term radio- Americium (Am) and toxicity of the Curium (Cm) waste.
Topics include the mechanisms of long-term uranium transport under oxidizing conditions, the structural chemistry of thorium iodates, the structural investigation of neptunium (IV) in toxicological processes, murataite ceramics doped with lanthanides and uranium, and the effects of hydrogen peroxide on the stability of becquerelite.
Another option is that of partitioning and the transmutation of the long-lived actinides, americium, curium and neptunium. This was described by Mr Schenkel as "the ultimate solution".
They therefore would become "burner" reactors for fissioning the plutonium and the minor transuranic elements, neptunium, americium, and curium, recovered from spent fuel from light water reactors.
In the wet reprocessing method, plutonium is mixed with neptunium and other radioactive elements that were discarded in order to make it harder for extracting pure plutonium that can be turned into nuclear weapons.
In 1940, he became one of the rare scientists to create a new element, Neptunium (element 93) after bombarding Uranium with neutrons.
Biokinetics of neptunium, plutonium, americium and californium in phytoplankton.
Long lived and high level waste (neptunium, plutonium, americium) can be destroyed in the flux of neutrons which exists in some reactors (called transmutation or incineration), even in conditions which are not up to normal security standards.
