PROCESS MONITORING CONCEPTS FOR SAFEGUARDS AND DEMONSTRATIONS AT AN OAK RIDGE NATIONAL LABORATORY TEST FACILITY.

As part of the Consolidated Fuel Reprocessing Program (CFRP) at the Oak Ridge National Laboratory (ORNL), the Integrated Equipment Test (IET) facility has been constructed to demonstrate advanced equipment, processes, and controls for use in future reprocessing plants. The facility contains full-size plant equipment for shear and dissolution, feed preparation solvent extraction, and product recovery. The facility is integrated with chemical recovery systems to allow continuous operation using depleted uranium feed solutions to simulate operations. This paper describes the IET facility and tests conducted to demonstrate sensitivities of process monitoring safeguards applications.
