mary tasks. Without such specific guidance, operators will make decisions on an ad hoc basis. Like dependent tasks, we can divide independent tasks into generic and plant- specific tasks. Further, the independent generic tasks can be categorized as: administrative tasks, communications, and system/equipment-related. Table 2 provides independent tasks in each of these categories. Note that some of these activities that can be either a primary, dependent, or independent task (e. g., technical specifications related activities). Table 2: Generic Independent Tasks Type of Independent Task Example Activities Administrative Technical specifications activities Apply error-prevention tools, such as independent verification of valve repositioning, unrelated to primary tasks Log keeping Drill participation Corrective action generation and processing Drug testing Outage schedule reviews Scheduling of operations, maintenance, and testing Training Communications Manage standard communications Communicate with auxiliary operators or fire brigade Shift turnover Staff meetings System/equipment-related actions Alarm monitoring and response for equipment unrelated to primary task 18.0-40 Revision 3 – December 2016 Applicants should also systematically analyze the plant design and the use of new technologies and new concepts of operations to identify if there are any plant-specific independent tasks that should be included. The following are examples of the types of activities to consider for identifying plant-specific independent tasks: • Work-related handling of conditions of one unit that impact other units • Data entries needed for using automation and computer-based human- system interfaces • Managing novel maintenance hazards (e. g., reactor cooling system (RCS) partial drain for steam generator (SG) tube inspections) • Modular construction and component replacement • Control actions and operations and maintenance (O&M) planning related to multiple modules A
