Abstract

These Systems were built for Westinghouse Hanford Company (WHC) for use in high level waste tank sampling operations performed by the Tank Waste Remediation Systems (TWRS) Project. A total of four, highly specialized Systems, designated as XRJ-001 through XRI-004 by WHC are referred to "on-site" as the x-ray "hot-dog" carts. The systems are used to remotely image the inner contents of specially designed, 26-inch length, one and one-half inch diameter, stainless steel core sample tubes and the high level radioactive waste contents following the remote sample segments removal from underground waste storage tanks. A real time radiographic view (x-ray) of the sampler and it's contents are displayed on live video monitors, is video taped, and selected "freeze-frame" image views can be immediately printed in the field. These images allow the field operations personnel to directly monitor sample recovery volume and the waste's physical characteristics, e.g., sludge, solid or liquid. This data provides a technical basis which allows the engineers to adjust the drilling/sampling platform operating parameters to optimize sample recovery efforts. Electrical power for x-ray systems (and all the associated sampling equipment) is provided by separate, portable diesel generators.
