tion) 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 scenarios should be sufficient provided they define what the applicant/licensee believes to be a set of the highest-workload conditions the operator might face. The applicant should use risk and cases of anticipated high workload to screen the scenarios and items contained in the scenarios. Additional Information: Workload can be anticipated to be high Selection and construction of scenarios: The applicant should use the results of Sections 1 through 4 to identify a reasonable set of scenarios for subsequent staffing for scenarios with the characteristics listed in Table 3. This table is not meant to be comprehensive, and the characteristics identified are not mutually exclusive, but they may be useful for identifying/constructing scenarios likely to induce high workload. b. Scenario Definition: For each scenario, the following information should be defined to reasonably assure that important dimensions of performance are addressed: • a description of the scenario and any pertinent prior history necessary for analysts to understand the state of the plant at the start-up of the scenario • specific initial conditions • events (e.g., failures) that will occur during the scenario and their initiating conditions, e.g., based on time, or a value of a specific parameter • dependent tasks related to each primary task • independent tasks that may occur during each scenario • definition of workplace factors, (e.g., environmental conditions) • needs for task support (e.g., procedures and technical specifications) • staffing level (should be the minimum levels are identified in the exemption request) 18.0-42 Revision 3 – December 2016 • responsibilities of each operator • communication requirements between control room personnel and remote personnel (e.g.,
