Expansion of DOE-DOT Tight Oil Research Work

The Departments of Energy and Transportation commissioned a technical team through Sandia to examine the properties of tight crude oils as they relate to potential combustion events in the rail transport environment. Key objectives of this investigation are to characterize and define tight crude oils based on their chemical and physical properties, and identify properties [...]

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 [...]
