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, NUREG-1764, “Guidance for the Review of Changes to Human Actions,” and NUREG-1852, “Demonstrating the Feasibility and Reliability of Operator Manual Actions in Response to Fire” for specific review guidance. 6. Local Control Stations Local control stations are not specifically addressed in the Commission’s regulations. However, staff often has to review changes to important human actions (risk-important human actions and certain deterministic human actions identified by the accident analyses) that are conducted using local control stations. In these cases, the staff uses a graded approach (see Section IV, “Review Procedures”) to evaluate those important human actions that are conducted from local control stations. 18.0-4 Revision 3 – December 2016 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 reviewed central and secondary alarm station HFE designs as there are
