Real-Time Mass Evaluation System (RTMES) performance during undeclared LEU production is examined through simulation. The RTMES is first outlined: the system would analyse load cell data collected continuously from the autoclaves and cooling chambers located in the feed, tails and product stations of a GCEP. These load cells are often installed for operational purposes. The term Real-Time is preferred to Near-Real-Time, because UF6 mass balances can be formed almost instantaneously. Mass balances are then shown for a number of different scenarios. Symptoms of undeclared LEU production are clearly visible.
