We have developed an active and passive computed tomography (A&PCT) scanner for assaying radioactive waste drums. Here we describe the hardware components of our system and the software used for data acquisition, gamma-ray spectroscopy analysis, and image reconstruction. We have measured the performance of the system using {open_quotes}mock{close_quotes} waste drums and calibrated radioactive sources. We also describe the results of measurements using this system to assay a real TRU waste drum with relatively low Pu content. The results are compared with x-ray NDE studies of the same TRU waste drum as well as assay results from segmented gamma scanner (SGS) measurements.
