3-D Earth model more accurately pinpoints explosions

During the Cold War, U.S. and international monitoring agencies could detect nuclear tests and measure their size. Today, they seek to pinpoint much smaller explosives tests. Under the sponsorship of the National Nuclear ...

Domestic production of medical isotope Mo-99 moves a step closer

(Phys.org) —Today, Los Alamos National Laboratory announced that for the first time, irradiated uranium fuel has been recycled and reused for molybdenum-99 (Mo-99) production, with virtually no losses in Mo-99 yields or ...

Collaborating to build a more efficient rocket

Sal Rodriguez, a nuclear engineer at Sandia National Laboratories, is forging a rocket revolution with the help of the University of New Mexico and student Graham Monroe.

Experiment improves predictions of uranium dispersion

The predictive models that describe the fate and transport of radioactive materials in the atmosphere following a nuclear incident (explosion or reactor accident) assume that uranium-bearing particulates would attain chemical ...

Testing virtual nuclear stockpiles

In 2010 the Pentagon revealed it had a total of 5,113 warheads in its nuclear stockpile, down from a peak of 31,225 at the height of the Cold War in 1967.

One million curies of radioactive material recovered

Los Alamos National Laboratory expertise helped the Department of Energy's (DOE) National Nuclear Security Administration (NNSA) Defense Nuclear Nonproliferation (DNN) Radiological Material Removal Program's Off-Site Source ...

Innate fingerprint could detect tampered steel parts

Researchers using magnetic signals have found unique "fingerprints" on steel, which could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.
