HFE evaluator usually provides a safety evaluation input on these manual actions which is embedded in the Chapter 7 safety evaluation. • Verify that the “important human actions” provided by the applicant are consistent with those identified in Chapter 15. This can done by reviewing the Chapter 15 application. If there are deviations subsequent actions should be coordinated through the Chapter 15 lead reviewer. • If the Chapter 18 submittal provides a separate list of risk important human actions this list should be verified against the list in Chapter 19. Often the Chapter 18 submittal will reference the Chapter 19 list directly in which case no additional interface is necessary. • The Chapter 18 safety evaluation related to the HFE design of the EOF and TSC should be sent to the lead reviewer for Chapter 13.3 for concurrence. 4. Verification that exemptions from regulations or alternative methods for complying with regulations have specific analyses that support them. a. Verify that applicants/licensees clearly identify methods and practices that are different from what the acceptance criteria advocate as alternate methods/practices. Evaluate the alternative on its own merits. The applicant is expected to provide an evaluation of how the proposed alternative provides an acceptable method of compliance. The justifications may be based upon evidence such as analyses of recent literature, analyses of current practices and operational experience, tradeoff studies, and the results of engineering experiments and evaluations. 18.0-14 Revision 3 – December 2016 b. Minimum staffing appears for small modular reactors to be the most imminent area where an exemption from 10 CFR 50.54(m) might be requested. The following NUREGs provide guidance in this area: • NUREG-1791, “Guidance for Assessing Exemption Requests from the Nuclear Power Plant Licensed Operator Staffing Requirements Specified in 10 CFR 50.54(m)” • NUREG/CR-6838, “Technical Basis for
