Abstract
The principal objective of the ORNL Integrated Safeguards Program (ISP) is to provide enhanced material accountability, improved process control, and greater security for nuclear fuel cycle facilities. With the improved instrumentation and computer interfacing currently installed, the ORNL 233u Pilot Plant has demonstrated capability of a nearreal-time liquid-volume balance in both the solvent-extraction and ion—exchange systems* Future developments should include the nearreal-time mass balancing of special nuclear materials as both a static, in-tank summation and a dynamic, in-line determination. In addition, the aspects of site security and physical protection can be incorporated into the computer monitoring.
