1 of NUREG-0700, Revision 1. Integrated system validation should be performed after HFE 53 problems identified in earlier review activities have been resolved or corrected because these may negatively affect performance and, therefore, validation results. The methodology for integrated system validation should address the areas identified in criterion 1 of NUREG-0711. Validation should be performed by evaluating dynamic task performance using tools that are appropriate to the accomplishment of this objective, as described in criterion 2 of NUREG-0711. The primary tool for this purpose is a simulator; that is, a facility that physically represents the HSI configuration and that dynamically represents the operating characteristics and responses of the plant design in real time. The requirement to validate performance at HSI components located outside of the main control room, such as remote shutdown panels and local control stations, will be dependent on the applicant's design. Human actions at facilities outside of the main control room may be evaluated using mockups, prototypes, or similar tools. Review considerations for conducting limited-scope evaluations using walk-through evaluations are described in criterion 4 of NUREG-0700, Revision 1.54 The objectives of validation evaluations should be consistent with criterion 3 of NUREG-0711 and criterion 1 of NUREG-0700, Revision 1. All critical or risk- 55 significant human actions as defined by the task analysis and the PRA/HRA should be tested and found to be adequately supported in the design, including the performance of such actions outside the control room. The design of tests and evaluations to be performed as part of HFE V&V activities should specifically examine these actions. The validation should evaluate selected activities based on procedures that are developed to address requirements of Appendix A of Regulatory Guide 1.33. Relevant categories of procedures are described in criterion 5 of NUREG-0711. The
