Safeguards performance model for evaluation of potential safeguards strategies applied to pyroprocessing facilities

Abstract

Electrochemical reprocessing has been proposed as a spent fuel disposition technique. If implemented on a commercial scale, traditional safeguards approaches used to satisfy IAEA requirements may be insufficient. To aid in testing safeguard strategies, a new tool was developed: the Pyroprocessing Safeguards Performance Model, a MATLAB/Simulink simulation of plant operations capable of calculating inventory differences for a specified balance period as well as sensitivity studies of detection measurements. This paper discusses the development of the model and a measurement uncertainty study performed using the model.
