Software Development for Analysis of LiDAR Pulsed Laser Measurements at the Savannah River Site

Oregon Convention Center 

Liquid radioactive waste is processed at the United States Department of Energy's (DOE's) Savannah River Site (SRS) in Aiken, South Carolina. An integral component of DOE's waste legacy waste management capability is SRS's H-Canyon, the only operating radiologically shielded chemical separations facility in the United States. One of the H-Canyon's supporting structures is the Air Exhaust Tunnel (H-CAEX). Because of radiation hazards in H-CAEX, the use of technology such as Light Detection And Ranging (LiDAR) is employed. In this work, we analyzed the LiDAR pulsed laser distance measurements of the recent inspection campaigns in comparison with the initial inspection in year 2019. Twelve sections with different heights and widths were considered within the tunnel. Certain segments of the inspected area appear to be eroding. The extent will be further investigated with future LiDAR deployments with semi-automated Python software that was developed.
