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 ...
