without using the risk screening methodology.. 5. Determine the Level of HFE Review. Based on the quantitative and qualitative information available, the staff should classify the HA into one of three risk regions in accordance with the review criteria of draft NUREG-1764. Region I HAs, high risk, are reviewed using the criteria in SectionC.2 below. Region II HAs, moderate risk, are reviewed using the criteria in Section C.3 below. Region III HAs, minimal risk, are reviewed using the criteria in Section C.4 below. C.2 Region I HFE Review HAs in the high-risk category should be reviewed using the Region I review criteria provided below: 1. General Deterministic Review Criteria. The applicant should provide adequate assurance that deterministic aspects of design, as discussed in RG .1.174, have been appropriately addressed. The staff should evaluated the'deterministic aspects of, the design, including that the change meets current regulations and does not compromise defense-in-depth, in accordance with the review criteria of draft NUREG-1764. 2. Operating Experience Review. The applicant should identify and analyze HFE-related problems and issues encountered previously in designs and human tasks that are DRAFT Rev. 1 - December 2002 18.0-14 similar to the planned modification so that issues that could potentially, hinder human performance can be addressed. The OER should address the operating histories of plant systems, HAs, procedures, and HSI technologies related to the proposed changes to HAs. The staffs evaluation should be conducted in accordance with the review criteria of draft NUREG-1764. 3. Functional Requirements Analysis And Functional Allocation. The applicant should define any changes in the plant's safety functions (functional requirements analysis), and provide evidence that the allocation of functions between humans and automatic systems provides an acceptable role for plant personnel; i.e., the allocations take advantage of human strengths and avoid
