Abstract The apparent renaissance in nuclear power has resulted in a new focus on nonproliferation measures. There is a lot of activity in development of new measurement technologies and methodologies for nonproliferation assessment. A need that is evolving in the United States is for facilities and test loops for demonstration of new technologies. In the late 1970s, the Fuel Recycle Division at Oak Ridge National Laboratory (ORNL) was engaged in advanced reprocessing technology development. As part of the program, the Integrated Equipment Test (IET) facility was constructed as a test bed for advanced technology. The IET was a full-scale demonstration facility, operable on depleted uranium, with a throughput capacity for 0.5 Mt/d. At the front end, the facility had a feed surge vessel, input accountability tank, and feed vessel for the single cycle of solvent extraction. The basic solvent extraction system was configured to use centrifugal contactors for extraction and scrub and a full-size pulsed column for strip. A surge tank received the solvent extraction product solution and fed a continuous operating thermo-syphon-type product evaporator. Product receiving and accountability vessels were available. Feed material could be prepared using a continuous rotary dissolve or by recycling the product with adjustment as new feed. Continuous operations 24/7 could be realized with full chemical recovery and solvent recycle systems in operation. The facility was fully instrumented for process control and operation, and a full solution monitoring application had been implemented for safeguards demonstrations, including actual diversion tests for sensitivity evaluation. A significant effort for online instrument development was a part of the program at the time. The fuel recycle program at Oak Ridge ended in the early 1990s, and the IET facility was mothballed. However, the equipment and systems remain and could be returned to service to support nonproliferation demonstrations. This paper discusses the status of the facility and operations.
