Development of MC and A alarm resolution procedures. [Material control and accounting]
The US Nuclear Regulatory Commission is reforming the material control and accounting (MC and A) requirements for facilities authorized to possess and use formula quantities of strategic special nuclear material (SSNM). The purpose of the reform is to strengthen MC and A capabilities by requiring more timely detection of possible SSNM losses and by providing for more rapid and conclusive resolution of discrepancies. This report provides guidance for developing a set of procedures to resolve alarms from the near-real-time loss detection systems. An alarm resolution program distinguishes between a system error and an actual loss of nuclear material. An alarm resolution program consists of procedures to identify causes of alarms, criteria for accepting resolution of alarms, and a program to monitor resolution effectiveness. Development of alarm resolution procedures consists of identifying potential causes of alarms, ordering the general elements of resolution, and determining criteria for accepting resolution. These criteria establish a basis to ensure consistent application of the procedures. A monitoring program is established to ensure acceptable performance of the resolution system.
