Examples of MC and A systems to meet prompt accountability specifications
Proposed regulations for NRC licensees authorized to possess and process formula quantities of strategic special nuclear material (SSNM) would require each licensee to implement a material control and accounting (MC and A) system capable of prompt loss detection and alarm resolution. In support of the loss detection and alarm response activities an overcheck program would also be implemented. This program would include personnel qualification and training, quality control, inventory verification and shipper-receiver transaction verification. However, the frequeny of physical inventory verification would be about once per year rather than once every two months. In addition MC and A activities would include procedures for the prevention and detection of data falsification and other forms of deceit that might undermine the performance of the loss detection and response systems. This report provides examples of prompt accountability systems for four plants: mixed oxide fuel fabrication, uranium hexafluoride conversion, high enriched uranium fuel fabrication, and high enriched uranium scrap recovery. Purpose of this report is to provide guidance to the MC and A system designer and evaluator on how the proposed requirements might be met.
