Operation of the Fast Neutron Coincidence Collar (FNCL) with a DD-Neutron Generator

Abstract

This report presents the initial performance results for both the integrated DD/FNCL [2] and Am(Li)/FNCL assays of compact depleted uranium, low-enriched uranium, and highly enriched uranium standards along with an estimate of the expected performance for fresh fuel assemblies. A discussion of the design and operation of the "FNCL Analysis and Simulation Software" [3] is also provided.
