nd 8.5, “Display location,” all identify human factor concerns. However, IEEE Std. 497-2016 does not identify any specific human factors guidelines or accepted human factors methods or principles. Consequently, applicants should consider Chapter 18, “Human Factors Engineering,” of NUREG-0800, which identifies guidance documents the NRC staff uses to determine if acceptable human factors engineering practices and guidelines have been incorporated into a plant’s design. These guidance documents include NUREG-0711, and NUREG-0700. Additionally, NUREG-0711 states that a practice, method, or guide is “accepted” if it is (1) documented in the human factors literature within a DG-1335, Page 11 standard or guidance document that underwent a peer-review process, or (2) is justified through scientific research or industrial practices. 9. The following corrections are addressed for clarity: a) IEEE Std. 497-2016, Section 4.7, the description of a Type F variable under the second column “Selection criteria for the variable type” of Table 1 “Summary of accident monitoring variable types/source documents” states: Monitor the direct effects (e.g. combustible gases concentration, radiation, pressure, or temperature of fuel damage). The wording “temperature of fuel damage” can cause confusion and in is clarified as follows: Monitor the direct effects of fuel damage (e.g. combustible gases concentration, radiation, pressure, or temperature). b) IEEE Std. 497-2016, Section 3, “Definitions,” revises the definition of anticipated operational occurrence (AOO). This term was already defined in 10 CFR Part 50, Appendix A, and the definition in previous versions of IEEE Std 497 was identical to the definition in 10 CFR Part 50, Appendix A. While it does not appear that the intent was to significantly change in the way the standard uses the term, the NRC only endorses the 10 CFR Part 50, Appendix A definition. DG-1335, Page 12 D.
