The Japan Atomic Energy Agency (JAEA) has embarked on an innovative project to develop a small nuclear battery that converts ...

The TBP solution captured the plutonium and uranium while the nitric acid/water solution retained ... SRS researchers optimized known methods of irradiating an oxide of Np-237 with neutrons to produce ...

including materials from mixed oxide (MOX) fuel and breeder reactors. It covers the safety issues relating to: the handling of spent fuel; mechanical treatment and the dissolution of spent fuel in ...

This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide ... in a rare form of uranium (U-235)—or converted into plutonium (Pu-239).

"The creation of heavy elements such as uranium and plutonium necessitates extreme conditions," said paper author Matthew Mumpower in a statement. "There are only a few viable yet rare scenarios ...

These consist of roughly 3% waste isotopes, 1% plutonium isotopes, and 96% uranium isotopes. This waste is high in transuranic elements, which have half-lives measured in many thousands of years.

Uranium in the environment is mainly found as a uranium oxide, typically as UO 2 ... small amounts of transuranics (elements heavier than uranium, such as neptunium, plutonium and americium) and ...

The milling and roasting into orange oxide at Oak Ridge becomes uranium tetrachloride or S-50 liquid thermal diffusion in the St. Louis plant, then into plutonium piles in Beverly, Massachusetts ...
