gn certification) C HFE-related design acceptance criteria (to verify that the applicant properly executes the design process after certification) For new NPPs (under 10 CFR Part 52), some HFE program elements may be deferred to the COL application. However, all HFE review criteria will be addressed before plant startup. 2. Review of the HFE Aspects of Control Room Modifications - The NRC staff conducts reviews of license amendment applications involving voluntary modifications of HFE aspects of HSIs. This chapter can be used to review changes or modifications to the control room and other significant HSIs. Modifications may be extensive, such as a large-scale modernization of control room HSIs, using computer-based technology as part of a digital instrumentation and controls (I&C) upgrade program. Such a program can result in substantial modifications to alarms, controls, and displays that are associated with SSCs important to safety. The NRC may also review certain plant modifications involving changes to the FSAR as part of the change process described in 10 CFR 50.59. Guidance related to 10 CFR 50.59 is provided in Regulatory Guide (RG) 1.187, “Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments,” and Nuclear Energy Institute (NEI) publication 96-07, “Guidelines for 10 CFR 50.59 Implementation.” 18.0-4 Revision 2 - March 2007 3. Review of the HFE Aspects of Modifications Affecting Risk-Important Human Actions - The NRC staff reviews modifications to ensure they are acceptable. This SRP chapter can also be used to review changes or modifications to licenses for nuclear power plants that include changes to human actions. While HSI modernization may be a large-scale modification, even smaller-scale modifications may be risk-important, especially when they affect operator actions that are credited in the safety analysis report (SAR). An HFE review is conducted if such a modification affects the role of personnel or the tasks they
