y addressed during task analysis to examine task details and confirm that these tasks are within human performance capabilities. Human actions that are identified as posing serious challenges to plant safety and reliability should be re-examined by function allocation analysis, task analysis, HSI design, or procedure development to change either the operator task or the control and display environment to reduce or eliminate undesirable sources of error. The adequacy of human performance associated with these human actions should be evaluated through verification and validation. Also, HRA assumptions such as decision-making and diagnosis strategies for dominant sequences should be validated by walkthrough analyses with personnel with operational experience using a plant-specific control room mockup, prototype, or simulator. G. Human-System Interface Design The objective of this review is to evaluate the HSI design process and the detailed HSI design that is a product of that process. The review should verify that the applicant has appropriately translated function and task requirements to the detailed designs of HSI components, such as alarms, displays, controls, and operator aids, through the systematic application of HFE principles and criteria. This review should verify that the control room design reflects state-of-the-art human factor principles as required by 10 CFR 50.34(f)(2)(iii). Acceptability of the HSI design activity should be based upon review findings that are consistent with the review criteria of Section 8.4 of NUREG- 0711. 31 The scope of HSI design should be consistent with the scope defined in the HFE program plan. For a new plant design, the scope of the HSI design is described in criterion 2 of NUREG-0711 and should include the following: overall work environment, workspace 32 layout (e.g., control room and remote shutdown facility layouts), control panel and console design, control and display device layout, and information and control
