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 [...]

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 [...]

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 [...]

Northrop-Grumman, GE Partnerships Tap a Wide Range of Sandia Labs Experience

Sandia has signed a pair of umbrella cooperative research and development agreements (CRADAs) with Northrop Grumman Information Systems and General Electric Global Research that will broadly add to the Labs’ research. “These strategic agreements envision long-term partner­ships,” said Brooke Garcia, a Sandia business development specialist who helped negotiate the CRADAs. The Northrop-Grumman CRADA includes research [...]

Cyber-Based Vulnerability Assessments

Digital Instrument and Control (I&C) is an integral part of the nuclear power industry in the United States. I&C systems monitor the safe, reliable and secure generation and delivery of electricity and could have potential cyber vulnerabilities. At Sandia National Laboratories, cyber-based vulnerability assessments are conducted on multiple I&C platforms deployed in the nuclear industry [...]
