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 [...]

Mechanical Testing

"Standard Test Methods for Tension Testing of Metallic Materials" E8/E8M-11, ASTM International (2008). ASTM standard (E8) used for tension testing guidance, with tests in constant displacement mode 2 tests were performed: at room temperature and at 650 °C Post-mortem metallography was performed on both samples Room-Temperature Tensile Test [...]

Diffusion Bonding Characterization

Research Goal 1. Tensile specimens prepared from diffusion-bonded block of 316/316L SS2. Micrograph showing good grain growth across the diffusion bond3. Small defects in bond area may not impact overall strength—but could lower design life, due to crevice corrosion Diffusion bond strength, defects, and corrosion behavior must be understood before they can [...]
