ation Notice (IN) 97-78, “Crediting of Operator Action In Place of Automatic Actions and Modification of Operator Actions, Including Response Times.” for further guidance). The NRC may also review certain plant modifications involving changes to the SAR as part of the change process described in 10 CFR 50.59. Additional guidance related to 10 CFR 50.59 is provided in RG 1.187 and NEI publication 96-07. Previous revisions of HFE guidance documents have focused on the review of risk important human actions. Experience is showing that there are additional human actions that need to receive similar reviews because they are specifically credited in design analyses. Consequently the guidance has been generalized to address important human actions as identified in: Operator actions credited in the diversity and defense in depth analysis supporting the diverse actuation system described in SRP, Chapter 7, “Instrumentation and Controls.” Operator actions credited in the design bases analyses described in SRP, Chapter 15, “Transient and Accident Analysis.” Risk-important human actions identified in the human reliability analysis contained in SRP, Chapter 19, “Severe Accidents.” The review guidance may also be useful in reviewing operator manual actions associated with fires especially alternate safe shutdown, flooding, beyond design basis events, and decommissioning activities. See Attachment A and NUREG-1764, “Guidance for the Review of Changes to Human Actions,” for specific review guidance. 6. Local Control Stations Local control stations are not specifically addressed in the Commission’s regulations. In practice the staff has used the graded approach (See Section IV, “Review Procedures”) to evaluate risk-important human actions that are conducted from local control stations. Applicants have found it useful to apply guidance in NUREG-0711 to the central and secondary alarm stations associated with security measures. The staff has historically not
