Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

We report non-equilibrium Molecular Dynamics simulations that provide a nanoscale view for the modeling of shock wave generation in any kind of material. Our methodology reported here is able to cover similar times and length scales as experiments. We are studying the propagation of shock waves, and their consequences: structural transformations and induced melting. We apply our methodology not only to single crystalline materials like Ta, W, but also in double layer conformations of bcc/fcc/bcc and bcc/bcc/bcc materials, with clear interest for Nuclear Fusion Technology. Preliminary results point that W and Ta behave more efficiently in terms of uniformity under shock propagation than lighter materials. Moreover, we show that shocks in double layer structures propagate and generate pressure more efficiently than common structures.
