Application of the active well coincidence counter (AWCC) to high-enrichment uranium metal
Technical Report
·
OSTI ID:6240601
The Active Well Coincidence Counter has been evaluated for the assay of high-enrichment uranium metal samples. Samples of interest to the International Atomic Energy Agency (IAEA), including stacked disks to simulate buttons and thin metal plates, were measured. Both thermal-neutron and fast-neutron interrogation modes were evaluated to extend the measurement range from a few grams to several kilograms of /sup 235/U. Neutron self-shielding and multiplication effects were studied, and measurement and calibration procedures have been developed for the AWCC. The results demonstrated that the instrument can be used for the assay of a wide range of high-enrichment uranium samples.
