Description and performance characteristics for the neutron Coincidence Collar for the verification of reactor fuel assemblies

Technical Report ·
DOI:https://doi.org/10.2172/6038728· OSTI ID:6038728

An active neutron interrogation method has been developed for the measurement of /sup 235/U content in fresh fuel assemblies. The neutron Coincidence Collar uses neutron interrogation with an AmLi neutron source and coincidence counting the induced fission reaction neutrons from the /sup 235/U. This manual describes the system components, operation, and performance characteristics. Applications of the Coincidence Collar to PWR and BWR types of reactor fuel assemblies are described.
