Recent HKED Instrumentations for Analytical Measurements in Conventional and Advanced Nuclear Fuel Reprocessing

Abstract

Two Hybrid K-edge Densitometers (HKED¿s) recently designed at ITU for different applications are presented and described. One of them, designated for installation in the RT-1 reprocessing plant of Mayak, Russia, follows the well-known route of standard HKED applications, i.e. the analysis of process samples from Purex type reprocessing. The second HKED is embedded into a more enlarged non-destructive assay (NDA) station including an additional neutron coincidence counter and a highresolution gamma spectrometer for the analysis of minor actinides in process samples originating from pyro-reprocessing test facilities at ITU. In addition, the paper also provides an evaluation of new HKED analysis software recently developed at the Los Alamos National Laboratory.JRC.E.8-Nuclear safeguards and Securit
