An automated nondestructive assay system consisting of calorimeters, a gamma-ray spectrometer and a sample handling system is described. The system utilizes isotopic ratio data determined by gamma-ray spectroscopy and calorimetric power measurements to determine the quantity of plutonium present in the sample. A minicomputer controls container movement, acquires and analyzes data and prepares reports. System components and operating characteristics are described.
