tial 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 representative set of independent tasks should be included in the scenarios to be analyzed (see Section 6). The applicant need not include independent tasks that are characterized by the following conditions: • An independent task that can be delayed or stopped to permit operators to accomplish the scenario-required primary tasks, and • An applicant has established guidance for prioritizing and/or postponing independent tasks that may arise during plant events b. Applicants should identify their assumptions regarding the status of these excluded independent actions, e.g., “we have not included drug testing actions in our analysis because we assume such actions will not interfere with the primary control tasks based on administrative procedures.” Trouble shooting and investigations Manage in progress activities (operations and maintenance) Manage plant configuration, e.g., equipment tag-outs, operational lineups, and operability evaluations Monitor plant risk using the safety or risk monitor Perform surveillance testing and post-maintenance testing Plant walkdowns Work related to unplanned shutdowns Participate in fire brigade 18.0-41 Revision 3 – December 2016 5. Construct Scenarios and Assign Operator Responsibilities Applicants should construct scenarios based on combining the primary, dependent, and independent tasks. These scenarios will be used to conduct the workload analysis described in Section 6. Scenario construction should follow the guidance contained in NUREG-0711, Sections 11.4.1.2, Identification of Scenarios, and 11.4.1.3, Scenario Definition) as adapted below. a. analysis. A given scenario may combine many of the characteristics identified in the “identification of challenging operating conditions” and other analyses. Five to ten
