EG-1764. These methods will result in a proposed Level (I, II, or III) for the review. Qualitative screening is then applied to the proposed level to see if it needs to be adjusted. Alternatively, the staff may choose to perform a deterministic review without using the risk screening methodology. Also, using guidance provided in SRP Chapter 19 and NRC Regulatory Issue Summary 2001-02, “Guidance on Risk-Informed Decision Making in License Amendment Reviews”, the staff may determine that “special circumstances” exist that could result in the staff requesting the license to submit risk information. Integrated Assessment of Human Actions Safety Significance. The integrated assessments of HA safety significance for non risk-informed applications is similar to that for risk-informed applications, but simpler because there are fewer inputs to integrate. C.1.3 Determine the Level of HFE Review. Based on the quantitative and qualitative information available, the staff should classify the HA into one of three HFE review levels in accordance with the review criteria of NUREG-1764. • Level I HAs, high risk, are reviewed using the criteria in Section C.2.1 below. • Level II HAs, moderate risk, are reviewed using the criteria in Section C.2.2 below. • Level III HAs, minimal risk, are reviewed using the criteria in Section C.2.3 below. C.2 Phase II - HFE Review C.2.1 Level I HFE Review HAs in the high-risk category should be reviewed using the Level I review criteria provided below. 1. General Deterministic Review Criteria. The applicant should provide adequate assurance that deterministic aspects of design, such as whether the change meets current regulations, does not compromise 18.0-20 Revision 2 - March 2007 defense-in-depth, and maintains sufficient safety margins, as discussed in RG 1.174, have been appropriately addressed. The staff should evaluate the deterministic aspects of the design in accordance with the review criteria of NUREG-1764. 2. Operating
