dc.description.abstractDevelopment efforts are in progress to enhance safeguards implementation at uranium enrichment facilities. One component of the enhanced safeguards approach for enrichment plants is the systematic tracking of UF6 cylinders between process and storage areas, and between different process areas. The challenges are: how to track the cylinders reliably with a minimum of operator involvement and to find the optimum location to install the monitor system to address all types of cylinders as well as to detect non-standard containers. A Laser Item Identification System (L2IS) has been successfully developed that is capable of monitoring all transfers of UF6 cylinders in/out of process areas. L2IS intrinsically identifies each cylinder by exploring the unique microstructure of the cylinder¿s surface. It has been demonstrated that each cylinder has a unique ¿fingerprint¿ which remains even under extreme environmental conditions. The system is composed of a portable unit, operated in attended mode, and a fix installed unit, operated without inspector¿s presence. The portable unit acquires the fingerprints of a given set of feed cylinders intended to be used over the coming months and the fixed system monitors the flow of previously identified cylinders in a transfer corridor. This system is coupled with standard video surveillance that can transmit remotely state of health information to IAEA HQ. The video surveillance can be interfaced with electronic seals applied to the cylinders to record and display seals data (e.g. status, time/date of operation). It is foreseen to integrate data from L2IS with data from the weighing and NDA stations to monitor and verify all transfers. This will provide a high deterrence of diversion or substitution, and detection of such an occurrence. The paper will describe the achievement of the L2IS after a year of field test, the intended use of the L2IS during inspection (SNRI and PIV) and the possible additional integration of other monitoring capabilities.
