Abstract
An alarm resolution program for nuclear material loss detection using process control data must be able to respond promptly to indications of loss and to distinguish between a systems error and an actual loss of nuclear material. A resolution program consists of procedures to identify causes of alarms, criteria for accepting resolution, and a quality assurance program. A quality assurance program consists of management reviews, audits, quality control activities, routine monitoring of control, and analyses to validate supporting data bases. A program to monitor resolution is necessary to ensure that resolution procedures are consistently applied and that resolution is representative of the causes of an alarm. The key elements in establishing a monitoring program are to develop measures of effectiveness and to properly identify what needs to be controlled.
