Resolving a Key to How Stars Transmit Energy

Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band. Because that role is much greater than […]

Consortium for Advanced Simulation of Light-Water Reactors To Receive Up To $121.5M Over Five Years

The Department of Energy approved the Consortium for Advanced Simulation of Light-Water Reactors’ (CASL’s) “Phase 2” renewal to develop advanced computing capabilities that serve as a virtual version of existing, operating nuclear reactors—to enable nuclear energy to continue to provide dependable, afford­able energy to America while advancing innovative research in an energy source central to […]

Sandia Magnetized Fusion Technique Produces Significant Results

Sandia Z-Machine researchers have produced a significant fusion-neutron output, using a method fully functioning for only little more than a year. The experimental work is described in a paper “Experimental Demonstration of Fusion-Relevant Conditions in Magnetized Liner Inertial Fusion,” published in the Oct. 6 Physical Review Letters online. A theoretical PRL paper, published on the […]

First-Ever Asian MELCOR User Group Meeting

The first-ever Asian MELCOR User Group Meeting was held in Daejeon, South Korea, from October 13–17. MELCOR (Methods for Estimation of Leakages and Consequences of Releases) is a fully integrated, engineering-level computer code whose primary purpose is to model severe-accident progression in light-water-reactor (LWR) nuclear power plants. Sandia developed MELCOR for the US Nuclear Regulatory […]

Recent Sandia International Used Nuclear Fuel Management Collaborations

On December 15, 2014, in Energy, News, News & Events, Nuclear Energy

During mid November, Evaristo (Tito) Bonano (senior manager of Sandia’s Advanced Nuclear Energy Group) and Sylvia Saltzstein (manager of Sandia’s Storage and Transportation Technologies Dept.) attended three meetings in Tokyo, Japan. The first two meetings focused on international R&D progress in storage and transportation of used nuclear fuel and were sponsored by the International Atomic […]
