following types of personnel tasks: • Important Human Actions – The sample should include all important HAs, as determined in NUREG-0711, Section 7. • Manual Initiation of Protective Actions – The sample should include manual system-level actuation of critical safety functions. • Automatic System Monitoring – The sample should include situations in which humans must monitor a risk-important automatic system. • Operating Experience - Identified Problematic Tasks – The sample should include high-workload personnel tasks identified as problematic during the applicant's review of operating experience. 18.0-35 Revision 3 – December 2016 • Range of Knowledge-Based Tasks – The sample should include tasks that are not well defined by detailed procedures (see NUREG-0711 for additional information). • Range of Human Cognitive Activities – The sample should include the range of cognitive activities that personnel perform, including: − detecting and monitoring (e.g., of critical safety-function threats) − situation assessment (e.g., interpreting alarms and displays to diagnose faults in plant processes and in automated control and safety systems) − planning responses (e.g., evaluating alternatives to recover from plant failures) − response implementation (e.g., in-the-loop control of plant systems, assuming manual control from automatic control systems, and carrying out complicated control actions) − obtaining feedback (e.g., feedback of the success of actions taken) • Range of Human Interactions – The sample should include the range of interactions among plant personnel, including tasks performed independently by individual crew members, and those undertaken by a team of crew members. These interactions among plant personnel should include interactions between: − main control room operators (e.g., operations, shift turnover walkdowns) − main control room operators with auxiliary operators and other plant personnel performing tasks
