Apr. 25—Trace amounts of plutonium from decades of weapons work at Los Alamos National Laboratory have contaminated the Rio Grande at least as far as Cochiti Lake and could be in the regional ...
She told BBC News that it paved the way to removing the cost and hazard of storing plutonium at Sellafield "by transforming it and locking it away into a solid, durable material that will last for ...
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons.
Plutonium–gallium–cobalt alloy (PuCoGa 5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current. [46] [50] Plutonium–zirconium alloy can be used as nuclear fuel. [51]
Today's moderated/thermal reactors primarily run on the once-through fuel cycle though they can reuse once-through reactor-grade plutonium to a limited degree in the form of mixed-oxide or MOX fuel, which is a routine commercial practice in most countries outside the US as it increases the sustainability of nuclear fission and lowers the volume ...
To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.
RENO, Nev. (AP) — The Latest on a federal court battle over the shipment of weapons-grade plutonium from South Carolina to Nevada (all times local):
Plutonium–gallium alloy (Pu–Ga) is an alloy of plutonium and gallium, used in nuclear weapon pits, the component of a nuclear weapon where the fission chain reaction is started. This alloy was developed during the Manhattan Project .
