Opening access to explore the synthetic chemistry of neptunium

Leftovers from nuclear reactors contain the element neptunium. To safely store the waste, scientists need to know more about how to control neptunium's chemistry. Knowing the stability of different oxidation states is central ...

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.

New Mexico nuke repository studied for plutonium storage

The U.S. Department of Energy has commissioned a national group of scientists to study the viability of diluting surplus weapons-grade plutonium and storing it permanently at the federal government's underground repository ...

Japan commission supports nuclear power despite Fukushima

Japan's nuclear policy-setting Atomic Energy Commission called Thursday for nuclear power to remain a key component of the country's energy supply despite broad public support for a less nuclear-reliant society.

Five workers exposed to radiation at Japan nuclear lab

Five workers at a Japanese nuclear facility that handles plutonium have been exposed to high levels of radiation after a bag containing highly radioactive material apparently broke during equipment inspection, the country's ...

New plutonium discovery lights way to clean up nuclear waste

Plutonium has long been part of many countries' nuclear energy strategies, but scientists are still unlocking the mysteries behind this complicated element and seeing how they can use heavier, nuclear elements to clean up ...

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 ...
