Abstract
Advanced MC&A methods are demonstrated which subdivide a uranium scrap recovery facility into control units which permit rapid detection of small SNM losses. This method utilizes frequent material balances plus data from process monitoring, accountability measurements, and quality control. The hypothetical facility, based on classical processes, was divided into ten and later eight control units. The latter selection optimized alarm capability to successfully meet the 5 kg U goal quantil r detection requirement for this example facility.
