2. HFE Design Verification. This review addresses both the method and the results of the HFE design verification. Acceptance should be based upon review DRAFT Rev. 0 - April 1996 18.0-14 findings that are consistent with the review criteria 1 and 2 of Section 11.4.3 of NUREG-0711. It should be verified that all aspects of the HSI have been designed to be (a) appropriate to personnel task requirements and operational considerations as defined by design specifications and (b) consistent with accepted HFE guidelines, standards, and principles. Deviations from accepted HFE guidelines, standards, and principles should be (a) acceptably justified on the basis of a documented rationale such as trade study results, literature-based evaluations, demonstrated operational experience, or tests and experiments, or (b) documented for resolution/correction. The process by which the HSI is compared against accepted HFE guidelines, standards, and principles should be consistent with Section 4.2.2 of NUREG-0700, Revision 1. Review considerations should 47 include: a. HSI Sampling. If all HSI components are not addressed individually by HFE design verification, then a multidimensional sampling methodology should be used to assure comprehensive consideration of the safety significance of HSI components, as described in criterion 2 of NUREG- 0700, Revision 1. The sampling methodology should select HSI 48 components that reflect a range of: plant conditions, operator functions (e.g., status monitoring, fault detection), task structure (e.g., procedure supported, knowledge-based tasks), interactions between plant personnel (e.g., with the Technical Support Center), critical and risk-significant human actions as defined by the PRA/HRA, and types of HSI components and user-system interaction tasks. In addition the sample should include all HSI components and associated personnel tasks that were identified as problematic during the OER. The sample size should be sufficient to identify all
