screening analysis to determine the risk associated with the plant modification and its associated HAs using both quantitative and qualitative information (see Section C.1 below): Plant modifications and HAs are categorized into regions of high, medium, and lowe'r risk. This categorization is used t6 determine the level of HFE review needed. Changes that involve more risk-significant HAs r6ceive a detailed review (see Section C.2 below), While those of moderate risk significaice receive a less-detailed review (see Section C.3 below). HAs in the lowest risk region-receive minimal HFE review (see Section C.4 below). C.1 Risk Screening Applicants should evaluate the risk associated with the proposed modification and the HAs associated -with it. The applicant's risk screening should be evaluated in accordance with the review criteria of "Guidance for the Review of Changes to Human Actions" (draft NUREG-1 764, December 2002). 1. Determine ithe Risk of the Entire Modification. The first review step is to perform a risk informed screening of the entire modification, including both equipment and HAs, in accordance with the review c'-iteria of draft NUREG-1764, for both permanent and temporary changes.- As part of this evaluation, the staff should determine whether the PRA information submitted as part of the risk-informed (R-1) submittal is suitable. The revi-•, critfeia defined in RG 1.174 an-d SRP Chapter 19 should be used. If the staff determines that the information is not suitable, a generic method screening process DRAFT Rev. I - December 2002 18.0-13 should be used (see item 4 below). RG 1.174 notes that licensee applications that lie in Region I are not normally permitted. If the entire modification is in Region I, the staff determines whether the modification is rejected. 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
