A review of nondestructive assay technology for enrichment plant safeguards is presented with emphasis on field experience. Actual and potential applications of this technology in domestic and international safeguards are described. Domestic applications of NDA emphasize verification of uranium enrichment in UF/sub 6/ storage cylinders and measurement of uranium in scrap and waste materials. International applications also would involve measurements to detect covert production of uranium enrichments above declared values. The state of development and application of standard techniques, e.g. gamma-ray and passive neutron assay of /sup 235/U in UF/sub 6/ cylinders, are reviewed critically based on experience at the US gaseous diffusion plants. Random driver measurements and segmented gamma scanning of wastes and trap materials are described. New instruments such as portable intrinsic Ge detectors and enrichment monitors for gaseous UF/sub 6/ are identified.
