22-Jul-2014 Sandia ensures US nuclear weapons deterrent can remain effective, credible
As part of its mission of ensuring the nation's stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they're hit by radiation, especially a type called fast neutrons. It created a science-based program called QASPR, which combines computer modeling and simulation, and experiments and technology development.
6-May-2014 What lies beneath
The effects of biogeochemical and geochemical processes in the ground under us are on massive scales. Understanding what's going on down there and how it effects what's going on up here is an enormous undertaking. Scientists working at EMSL are getting a handle on these gigantic macroscopic processes by focusing on the microscopic scale. By creating micromodels and incorporating supercomputer simulations, researchers are connecting the molecular level with processes that affect our entire ecosystem.
15-Apr-2014 Wind tunnel tests support improved aerodynamic design of B61-12 bomb
Sandia National Laboratories has finished eight days of testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel.
The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system, the B61-12.
15-Jan-2013 Sandia airborne pods seek to trace nuclear bomb's origins
If a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for analysis.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
