5D - U3O8 - Assay - DNC

Total uranium can be determined by delayed neutron counting using an automated Delayed Neutron Counting system at a nuclear reactor. Samples are irradiated in series for a brief period, the samples are then transferred under computer control to a delayed neutron counter which is an array of six BF3 detectors and neutrons emitted from the fissioning U-235 is thermalized and counted. The principle advantage of this technique is it provides very rapid and accurate assays of uranium for high volumes of samples at a very low cost. The upper limit of this technique is 1% U. Results can be reported as U or U3O8. From 1 to 10% fusion XRF will provide the best quality assay results and above 10% titration is recommended for accuracy.
