jected. If it is rejected, then no additional HFE review is needed. If it is not rejected, the staff determines whether the modification contains only HAs or if it includes both equipment and HAs.- If the modification contains only HAs (no equipment modifications) and was determined to be in Region I, then the HA should be reviewed using the Region I criteria in Section C.2 below. If the modification contains equipment and HAs, then the risk importance of the HA should be evaluated (see item 2 below). 2. Determine the Risk of the HAs. The second review step is to perform a risk-informed screening of the HA portion of the modification in accordance with the review criteria of draft NUREG-1764. This is done by evaluating both the risk achievement worth (RAW) and the Fussell-Ves6ly (FV) risk importance measures. HAs will be preliminarily sorted into the three Regions. 3. Perform Qualitative Screen of the HAs. The third risk-screening step is to identify whether there are qualitative factors that should be taken into account when determining the risk importance of the HA. This ýtep may be used to adjust the review region either up or down. This evaluation should in accordance with the review criteria of draft NUREG-1764. 4. Review of Non-Risk-Informed Submittals. In keeping with RG 1.174, a licensee submittal to the NRC may be risk-informed (R-1) or not at the licensee's option. If it is not R-1, then the staff may choose to-Use the Generic Method to determine risk in accordance with the review criteria of draft NUREG-1 764. The Generic Method will result in a proposed Region (I, II, or Iii) for the review. Qualitative screening is then applied to the proposed region to see if it needs to be adjusted. Alternatively, the staff may choose to perform a deterministic review 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
