X Ray Tomography of Intact Hanford Cores
EMSL Project ID
51822
Abstract
We propose to use XCT to generate 3-D images of sediment cores to aid in describing the physical characteristics of the subsurface. Intact core from the Hanford Central Plateau require sediment characterization to support hydrogeophysical characterization efforts. Sediment core samples will be selected from a core inventory stored in 331 building. These cores may be considered radiological material or Environmentally Controlled Material (ECM). XCT will provide 3-D morphological information on the internal grain and pore structure of intact sediment cores and help guide the selection of sediment samples best suited for additional characterization in the laboratory. For example, XCT can identify larger sediment particles within the cores as well as information on defects and locations of void spaces that may impact results for intact column transport experiments. These data will contribute to a broader characterization of the physical and hydraulic sediment properties including lithology, density, moisture content, particle size, and porosity.
