Abstract
Blending a highly enriched UF/sub 6/ gas stream with low-enrichment material reduces the excess supply of highly enriched uranium that must be closely controlled for nonproliferation of nuclear weapons. Computer simulations and feasibility experiments show that inducing fission in /sup 235/U provides means for monitoring the blending process. Detecting delayed fission neutrons or gamma rays after fission products drift downstream in the gas gives a measure of /sup 235/U content and flow velocity. At very low UF/sub 6/ gas pressures (5 mm Hg) where the downstream signal is too weak for use, an alternative technique based on attenuation of thermal neutrons passing through the UF/sub 6/ gives a measure of /sup 235/U content.
