Unexpected oxidation state for molecular plutonium discovered

Researchers at Los Alamos National Laboratory in collaboration with the University of California - Irvine (UCI) have uncovered a significant new chemical attribute of plutonium, the identification and structural verification ...

Improving detection of radioactive material in nuclear waste water

As the Fukushima crisis continues to remind the world of the potential dangers of nuclear disposal and unforeseen accidents, scientists are reporting progress toward a new way to detect the radioactive materials uranium and ...

Former Colorado nuke site opens to public as wildlife refuge

Cyclists and hikers explored a newly opened wildlife refuge at the site of a former nuclear weapons plant in Colorado on Saturday, while a protester in a gas mask brought signs warning about the dangers of plutonium.

High plutonium breeding of light water cooled reactors

Professor Oka and his research team at Waseda University have succeeded in developing the world's first conceptual nuclear reactor design of high plutonium breeding by light water cooling.

Antineutrino detectors could aid non-proliferation

Physicists at the Large Hadron Collider in Switzerland and even in the fictional world of CBS' "The Big Bang Theory" look to subatomic particles called neutrinos to answer the big questions about the universe.

Probing what happens to plutonium in a nuclear explosion

For years, research on nuclear weapons has relied on old data, limited experiments and computer modeling. But this year, that pattern has changed. Scientists have run new experiments that simulate what happens to plutonium ...

Time to tackle the UK's plutonium mountain

Professor Neil Hyatt, Research Chair in Radioactive Waste Management, calls for UK plutonium policy to be re-examined to allow swift immobilisation of UK's civil plutonium stockpile to maximise safety, security and affordability ...

N-test legacy in stratosphere bigger than thought

Levels of radioactive plutonium in Earth's stratosphere from nuclear tests and accidents is higher than previously thought, but probably not dangerous to humans, scientists in Switzerland said Tuesday.

Plutonium at 150 years

Planning the future needs of the U.S. nuclear weapons stockpile as well as the nuclear weapons complex depends in part on maintaining confidence in the long-term stability of the pit, or core, of plutonium-239 residing inside ...
