Nondestructive assay of fissile material samples in support of nuclear safeguards

Description: From nuclear science symposium; San Francisco, California, USA (14 Nov 1973). Samples of fissile material can be assayed by bombarding with 300- to 600- keV neutrons and counting delayed neutrons from fission. Interrogating neutron energy selection is based upon considerations of sample penetrability and insensitivity of response to nonfissile isotopes. Significant cost savings in nuclear safeguards and quality control are possible. (auth)

UF$sub 6$ enrichment monitor: operating procedures manual

Description: This manual describes the construction and operation of a UF/sub 6/ enrichment monitor for the continuous measurement of percent /sup 235/U and percent /sup 234/U in a liquid UF/sub 6/ stream. The system uses a gamma enrichment meter to measure /sup 235/U and /sup 3/He neutron detectors to measure /sup 234/U. It is presently installed at the Goodyear Atomic Corporation gaseous diffusion plant in Piketon. Ohio. (auth)
