Nuclear material tracking system testing

A concept for a Nuclear Material Tracking System (NTRAK) and details of its operation have been developed at the Westinghouse Hanford Company. The NTRAK development is sponsored by the US Department of Energy (DOE). The NTRAK system is intended to help nuclear facilities meet the performance requirements of DOE Order 5633.3(1) and provide greater tracking capability and flexibility than is provided by current special nuclear material detection systems. The NTRAK testing, during its first year of development, is designed to verify concept feasibility, provide basic detection probability information of the NTRAK Detection Probability Prediction Program (NPROB), and verify detection probabilities predicted by NPROB. This paper reports on the results of testing accomplished in fiscal year 1988 and part of 1989. 3 refs., 12 figs.
