This article is part of “The New Nuclear Age,” a special report on a $1.5-trillion effort to remake the American nuclear arsenal. In early nuclear bombs, like the ones the U.S. dropped on Japan in ...

Instead of burying plutonium and pretending it has disappeared, we can put it to work. With advanced fast reactors, like those being developed by private American innovators, stored fuel will be ...

The U.S. Department of Energy (DOE) has reportedly decided that weapon-grade plutonium from the Cold War-era stockpile could be turned into nuclear reactor fuel. The DOE will give American companies ...

Outdone only by nuclear fusion, the process of nuclear fission releases enormous amounts of energy. The ‘spicy rocks’ that are at the core of both natural and artificial fission reactors are generally ...

Repurposing surplus plutonium as reactor fuel could cut costs, ease the advanced nuclear fuel bottleneck, and offer a more permanent nonproliferation solution than dilute and dispose. America has some ...

As it was said (and sang) in 1979, plutonium is forever…with thousands of years of radioactivity from nuclear fission (especially plutonium 239). Jeff Bezos—proving again that he is not Democracy’s ...

Deep Fission has signed an LEU supply agreement with Urenco to support Gravity Reactor testing and early operations under the ...

Lawrence Livermore National Laboratory scientists have trapped a single plutonium atom inside a tiny molecular cage, using only six micrograms of the radioactive metal. The work turns an element ...
