on 3 – July 2015 5. Verification that HFE design effectiveness has been demonstrated in a performance based integrated system validation test. a. The HSI is subjective due to the potential for human error and is therefore difficult to describe via codes, calculations, and physical properties as would be done for electrical/mechanical systems. Therefore an integrated system validation (ISV) is used to validate the design effectiveness. Where feasible the ISV should be subject to an inspection or audit to verify the HFE design supports the operator actions being credited in the licensing documentation. b. Because of the ISV’s dependence on operator programs (procedures, training), the ISV may sometimes be submitted at the implementation plan level with performance of the ISV tracked as an ITAAC under the guidance of SECY 92-053. In this case the implementation plan must contain specific acceptance criteria describing how the ISV will be performed. The acceptance criteria should be identified as Tier 2* information. c. In the case of operating reactors, the ISV must be complete prior to implementation of the proposed action or program. In the rare cases when this cannot be done, such as when the simulator upgrade is not yet complete, acceptance or approval may be based on a smaller scale “preliminary” ISV and a license condition that states that the full-scale ISV will be completed and provided to the NRC staff by a specific date. V. EVALUATION OF FINDINGS The reviewer verifies that the applicant has provided sufficient information and calculations (if applicable) to support their conclusions. The reviewer also states the bases for their conclusions. Conclusions of the following type should be included in the staff's safety evaluation report (SER). 1. The reviewer’s determination that all review criteria are satisfied, using the methods described in the SRP. 2. The reviewer’s determination that alternative means of satisfying review criteria are acceptable.
