Plutonium is radioactive, but it doesn't seem that harmful at first glance. It looks like any other metal, with a silvery sheen that turns dull in contact with the air. Queen Elizabeth II held a ...

The UK's 140-tonne stockpile of civil plutonium could be used as fuel for thermal reactors or combined with the country's 100,000-tonne supply of depleted, natural and low-enriched uranium to fuel new ...

Lightbridge Corporation has several thermal reactor fuel designs that offer very high burnups, in the range of 21 at. % or approximately 190 900 MWd/tonne of heavy metal, which make them well suited ...

A plan to dilute and dispose of excess plutonium dating back to the Cold War was frozen by an executive order President Donald Trump issued late last month. Instead, the order directs Energy ...

One scientist called it a “supernova graveyard.”Plutonium discovered at the bottom of the ocean was found to be refuse from a kilonova that exploded close to Earth 10 million years ago ...
