Nuclear reactors constructed for “peaceful” purposes to generate electricity nevertheless constitute a danger in that they generate fissionable isotopes of plutonium, neptunium and americium and, are not under strict international control. Since 1945, more than 3,000 metric tons (3,000,000 kilograms) of highly enriched ...
You might as well try to reach Neptunium or Plutonium by yourself! Perhaps another university's accomplishments might be more within your reach. We know you've been saying that it's been a long time since we discovered Astatine, but there's no need to be bitter. It wasn't so long ago that Seaborgium ...

In brief, the process goes like this: Neptunium-237 (another Cold War-era byproduct, and the key starter material to make Pu-238) is shipped from Idaho National Laboratory to Oak Ridge National Laboratory in Tennessee. At ORNL, it's formed into reactor-ready targets. Those targets are irradiated for many ...
The precursor to plutonium- 238 is neptunium-237, a radioactive by-product of nuclear power plants. Oak Ridge gets its neptunium trucked in from Idaho National Laboratory in a powdery form called oxide. When it arrives, it's deposited via a dumbwaiter-like system in a shielded room called a hot cell.

Let them eat waste. Bacteria could not only thrive on nuclear waste dumped underground, but may immobilise it and make it safer. Experiments have shown that certain microbes can make use of radionuclides such as uranium and neptunium in place of oxygen. In doing so, they convert them from soluble ...
Here's how it will work. PNNL has developed new technology for producing "targets" made of neptunium-237, Shipp said.

Neptunium, element 93 on the periodic table of elements, was the first transuranium element to be produced synthetically and the first actinide series transuranium element to be discovered. Its discovery came after several false findings of the element, including Enrico Fermi's attempt to bombard uranium ...
Mercury. The symbol for Mercury is Hg and its density g/cm3 is 13.53. Molybdenum. The symbol for Molybdenum is Mo and its density g/cm3 is 10.2. Neodymium. The symbol for Neodymium is Nd and its density g/cm3 is 7.01. Neptunium. The symbol for Neptunium is Np and its density g/cm3 is 20.2. Nickel.
At alkaline pH of 10.5, XAS showed that uranium (VI) and neptunium (V) were substantially bioreduced to less soluble and less mobile uranium (IV) and neptunium (IV), then scavenged onto the natural soil minerals. For the first time, these experiments highlighted the possibility for biogeochemical control ...
The research conducted at ACE will integrate both experimental and computational approaches to analyze radioactive materials, including the elements americium, neptunium, plutonium and uranium, taking advantage of specialized facilities developed at Notre Dame. Further, the team of researchers will ...

TRU-waste is anything contaminated by heavy radioactive elements from working with materials like plutonium and neptunium. Primarily, the material consists of gloves, safety equipment and other materials - not the heavy metal elements themselves.
My name is Vina Colley, and I am a sick worker from the former DOE controlled Portsmouth Gaseous Diffusion Plant in Piketon, Ohio.
The Jews reckoned that 237 appears in the Book of Numbers in the Torah indicating that 237Np (Neptunium) must never be made, let alone buried anywhere on the planet.

What's Next? Cho and his colleagues are continuing to delve into the nuances of plutonium as well as uranium, neptunium, thorium, and similar complex actinides to understand how these elements interact with other atoms and groups of atoms.
TRU waste is artificially made radioactive material contaminated with heavier elements, or those with higher atomic numbers, than uranium, including plutonium and neptunium. The letter was entered into court records by the South Carolina counsel in its ...
It involves storing the radioactive elements deep underground long enough to "run out the clock" on the materials so they are no longer radioactive.
