Title: Study of kinetics of a PGNAA system for nondestructive characterization of mixed waste

Abstract

Pulsed gamma neutron activation analysis (PGNAA) is a promising method for accurate nondestructive assaying of heavy metals (Cd, Hg, Pb) in mixed waste. A laboratory PGNAA system was developed by the Westinghouse Science and Technology Center (WSTC). The system proved to be very successful in a blind-test performance evaluation study, by the US Department of Energy (DOE) and the Idaho National Engineering and Environmental Laboratory, employing 8-gal drums. The DOE is currently supporting development of a commercial system for characterization of 55-gal drummed mixed waste through joint efforts of the Penn State Transport theory Group (PSTTG), WSTC, and Canberra. A transport theory methodology was established by PSTTG for accurate simulations of such systems. These simulations will be used in support of the design of the full-size system for assaying 55-gal drums and to optimize system performance. Herein the authors introduce the methodology, present results of simulations, and discuss neutron kinetics and its impact on the system performance.
