dered in the analysis, (7) consideration of multiple units and other radiological sources on the site, and (8) uncertainty/sensitivity analysis performed. c. Addition: Additional information for human factors considerations: If not included in SAR Chapter 6 or 7 an applicant should also address human factors considerations such as operating experience review, safety function review, human action task analysis, human-system interface design, procedures, training, verification and validation, and human performance monitoring. Guidance on ensuring a holistic approach to the human factors engineering program appears in the draft ARCAP ISG, DANU-ISG-2022-05, “Organization and Human-System Considerations,” (Ref. 38). d. Addition: In Chapter 4 of the SAR, the applicant should discuss how changes to the design are assessed for possible effects on the DID analysis. In particular as described in NEI 18-04, Revision 1, and RG 1.233, in describing the change control process, the applicant should address how it will reevaluate the baseline DID evaluation results to determine which programmatic or plant capability attributes in each layer of defense would be affected by proposed changes. Changes that affect the definition or evaluation of LBEs, the safety classification of SSCs, or the risk significance of LBEs or SSCs should be assessed. 6. Safety Functions, Design Criteria, and SSC Safety Classifications Section C.5 of NEI 21-07, Revision 1, provides guidance on the information related to safety functions, design criteria, and SSC classification established using the LMP process in NEI 18-04, Revision 1, and endorsed in RG 1.233. In the LMP process, LBEs are generally defined in terms of successes and failures of SSCs that perform safety functions and are modeled in the PRA. Therefore, the PRA safety functions (PSFs) are those functions credited for preventing or mitigating unplanned radiological releases from any source within the plant. Chapter 5 of a SAR following NEI
