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 [...]

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 Room-Temperature Metallography [...]

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 [...]

Nuclear Energy Systems Laboratory (NESL) / Transient Nuclear Fuels Testing

Sandia National Laboratories is home to the United States’ only operational pulsed nuclear reactor capable of a comprehensive range of transient nuclear fuels testing. The Annular Core Research Reactor (ACRR) was specially designed to provide high power pulses (up to 300-MJ) in very short amounts of time (6-millisecond pulse-width), which allows the ACRR to compete [...]

Nuclear Energy Systems Laboratory (NESL) / Brayton Lab

Nuclear Energy Systems Laboratory (NESL)/Brayton Lab Sandia National Labs has established the Nuclear Energy Systems Laboratory (NESL)/Brayton Lab to research and develop closed Brayton cycle (CBC) technology for highly efficient thermal-to-electric power conversion. While CBC’s have generated power since 1939 using air as the working fluid, the testing at Sandia’s Brayton Lab [...]
