Near real-time accountability system at the Oak Ridge Y-12 Plant
The Oak Ridge Y-12 Plant maintains a nuclear materials control and accountability system on a computerized network identified as DYMCAS (Dynamic Special Nuclear Materials Control and Accountability System). This near real-time system was initiated in 1976 and brought on line as the offical accountability system at Y-12 in April 1982. The system was designed to assist in the detection of diversion of special nuclear material and to provide timely and accurate accountability data for both routine and emergency inventory activities. In the approximately two and one-half years of on-line operation, the system has functioned quite satisfactorily in response to both routine and non-routine situations. The system remains dynamic in the sense that it is still being modified and upgraded to improve its response capability to the ever-evolving set of safeguards scenarios. This paper will discuss the development, operation, and future of the DYMCAS. 4 refs.
