Evaluation of a random driver for Y-12 in-plant applications

Creators

Description

A random driver neutron interrogator has been evaluated for application to measurements of process residues at Y-12. The unit has been demonstrated to provide rapid, accurate, and nondestructive assay of the uranium content of U3O8 skull oxide and unleached solids. Accuracy [expressed as systematic error (bias)] on both material types is better than 1%. A precision of 3% (1 standard deviation) for skull oxide assay is equivalent to that exhibited by currently used sampling and chemical analysis techniques. This precision is limited by short-term instrument instabilities. The precision of unleached solids assay is limited by counting statistics to about 4%
