Bill Glass is a technical advisor at Pacific Northwest National Laboratory (PNNL) and supports the Non-Destructive Evaluation (NDE) team for the National Security Directorate. His work focuses on NDE and particularly high temperature nuclear component NDE, materials characterization in support of NDE for nuclear components, cable NDE, Department of Energy-spent fuel canisters, and the Hanford reservation waste tank inspections. Glass also provides strategy and development in support of leadership via capabilities presentation and contacts to the special weapons and tactics team.
