Containing a nuclear accident with ground-up minerals

Sandia’s injectable materials could stop contamination from spreading By Kristen Meub Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. During a three-year Laboratory Directed Research and Development project, a [...]

Sandia technology may substantially reduce thermoelectric power water usage

Thanks to technology created by Sandia researchers, cooling power plants using significantly less water may someday be a reality. The technology uses a thermodynamic cycle for a cooling loop that makes it easier to transfer heat into the air. Basically, this means matching the temperature of the working fluid to that of the air receiving [...]

Sandia Assists NASA in Understanding Launch-Area Accidents

Curiosity’s multi-mission radioisotope thermoelectric generator on Mars. Some NASA spacecraft, those which operate on the surface of other planets or are too far from the sun, require the use of radioisotope power systems (fueled with plutonium dioxide) to produce electricity and heat. In the unlikely event of an early launch accident, these DOE-provided [...]

University of Wisconsin–Sandia Team Awarded SunShot CSP: APOLLO Funding

With recently awarded funding from the US Department of Energy SunShot Initiative’s CSP: APOLLO Program (Concentrating Solar Power: Advanced Projects Offering Low LCOE Opportunities), Sandia is working with a team led by the University of Wisconsin–Madison to evaluate the potential for significant improvements in the commercial viability of supercritical carbon dioxide (sCO2)/Brayton-cycle power conversion as [...]

Sandia’s Supercritical Carbon-Dioxide/Brayton-Cycle Laboratory Signs Important MOU with Industry Partners

Sandia and eight other companies and research organizations* will collaborate to advance a distributed power system that can produce cleaner, more efficient electricity. The memorandum of understanding (MOU) focuses on developing an energy-conversion system based on supercritical carbon dioxide (sCO2)/Brayton-cycle technology. Gary Rochau, manager of Sandia’s Advanced Nuclear Concepts Dept. said sCO2/Brayton cycle technology could [...]

Sandia Research Featured on Journal of Physical Chemistry A Cover

As part of Sandia’s core geochemistry program funded by DOE Office of Basic Energy Sciences (BES), Sandia’s Randall Cygan (in Sandia’s Geoscience Research and Applications Dept.) and his collaborators, W. Crawford Elliott and his PhD student Laura Zaunbrecher from Georgia State University, have been examining the adsorption mechanisms of metal cations onto soils and sediments. [...]

Sandia Nuclear Power Safety Expert Elected to National Academy of Engineering

Dana Powers, a recently retired Sandia senior scientist and nuclear safety expert in Sandia’s Advanced Nuclear Energy Programs, who studied the Three Mile Island and Chernobyl nuclear power plant accidents during his more than 40-year career, was elected a member of the National Academy of Engineering (NAE) “for contributions to commercial nuclear power plant safety [...]

Sandia Teaches Nuclear Safety Course

Measures for keeping nuclear materials out of the wrong hands can be as straightforward as a stout post beam designed to stop massive, speeding trucks in their tire tracks—or they can be as complex as fencing draped with a web of sensors so acute they can differentiate the movements of men from those of jackrabbits. [...]

Sandia–Univ. of Rochester Win Funding to Demonstrate Fuel Magnetization and Laser Heating Tools for Low-Cost Fusion Energy

Sandia and the Laboratory for Laser Energetics (LLE) at the University of Rochester will investigate the compression and heating of high energy-density, magnetized plasmas at fusion-relevant magneto-inertial [confinement] fusion (MIF) conditions, building on the recent Magnetized Liner Inertial Fusion (MagLIF) concept successes. The SNL-LLE team will conduct focused experiments based on the MagLIF approach at [...]
