Nuclear weapons haven’t been tested in the United States since 1992. Find out why, and what could happen if the hiatus ends.

The second American company has secured an export licence to sell nuclear technology to India in nearly two decades, opening ...

A recently passed resolution by San Diego County seeks partnerships with national labs and companies to reprocess the waste ...

We have measured the mass-yield distribution from the fission of Pu240 induced by fast neutrons from a plutonium metal critical assembly. Measurements were made for 44 fission products from Zn72 to ...

The UK's Nuclear Decommissioning Authority announced it has succeeded in safely processing a can of plutonium residue into a stable waste form for the first time, marking a significant step toward ...

Scientists have now pulled reactor secrets out of fuel grains smaller than many dust particles. Tiny fragments collected near Chernobyl still hold trapped radioactive gases that record how the damaged ...

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 ...

Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries ...

In the framework of the adiabatic binary model, calculations of yields for heavy transuranium nuclei production were made for “Mike”, “Par” and “Barbel” thermonuclear explosions, performed in USA. It ...

The Trump Administration is proposing to make 20 metric tons of plutonium from dismantled nuclear warheads available to U.S. power firms for use in advanced nuclear reactors. This plan follows an ...

Fast reactors use “fast neutrons” (not slowed by a moderator like water), which allows them to fission a broader range of isotopes, including plutonium and minor radioactive elements found in spent ...
