review of actual HSIs, the staff can use the guidelines to evaluate a design-specific HFE guideline document (style guide), control room modifications, local control station layouts, and control room reconfiguration modifications that might occur during decommissioning. 3. Attachment A, “Guidance for Evaluating Credited Manual Operator Actions,” provides acceptance criteria for evaluating important human actions. 4. Attachment B, “Methodology to Assess the Workload of Challenging Operational Conditions In Support of Minimum Staffing Level Reviews,” a methodology to identify high-workload operational conditions and analyze the workload associated with them. The methodology is rooted in task analysis and relies on the identification of appropriate challenging scenarios, realistic portrayals of task performance that is complicated by separate, but often necessary, dependent and independent tasks, and the judgment of SMEs obtained in a manner conducive to obtaining realistic workload estimation. 5. NUREG-1764 is particularly useful when evaluating changes resulting from plant modifications, procedure changes, equipment failures, justifications for continued operations, and identified discrepancies in equipment performance or safety analyses. This guidance uses a graded, risk-informed approach that is consistent with RG 1.174, “An Approach to Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis.” As such, this guidance uses risk insights to determine the level of regulatory review the staff should perform. This approach can be accomplished for licensee submittals that are either risk-informed or non-risk-informed. Human actions that are considered more risk-significant receive a detailed review, while those deemed less significant receive a less detailed review. When a human action is significant the analysis method described in Attachment A is a useful complement to the guidance in this NUREG. IV.
