Technical Report ·
DOI:https://doi.org/10.2172/6773623· OSTI ID:6773623

A neutron interrogation assay system is being designed for the measurement of waste canisters and spent fuel packages at the new Idaho Chemical Processing Plant to be operated by Allied Chemical Corp. The assay samples consist of both waste canisters from the fluorinel dissolution process and spent fuel assemblies. The assay system is a /sup 252/Cf ''Shuffler'' that employs a cyclic sequence of fast-neutron interrogation with a /sup 252/Cf source followed by delayed-neutron counting to determine the /sup 235/U content.
