with this attachment. Important human actions as defined by NUREG-0711, “Human Factors Engineering Program Review Model,” and their associated interfaces (controls, displays, and alarms) should be specifically addressed in the applicant/licensee’s human factors engineering (HFE) program related submittals. PHASE 1: ANALYSIS This section describes the attributes of an acceptable method of analyzing the time available and time required for manual operator actions that are to be credited in an event analysis. 1.A. Method The analysis must demonstrate that: • The time available to perform the required manual actions is greater than the time required for the operator(s) to perform the actions. 18.0-18 Draft Revision 3 – July 2015 • The operator(s) can perform the actions correctly and reliably in the time available. The time available to perform the actions should be based on analysis of the plant response to the event of concern. The time required for operator action should be based on an HFE analysis of operator response time. The basis of the documented sequence of operator actions can be task analysis, vendor-provided generic technical guidelines for emergency operating procedure development, or plant- specific EOPs, depending on the maturity of the design. The documented sequence of operator actions should be analyzed at a level of detail necessary to identify critical elements of the actions and performance shaping factors (e.g., workload, time pressure) that affect time required and likelihood of successful completion of the action sequence. The licensee/applicant should establish time estimates for individual task components (e.g., acknowledging an alarm, selecting a procedure, verifying that a valve is open, starting a pump) and the basis for the estimates, through a method applicable to the human-system interface (HSI) characteristics of the control system. The vendor/licensee/applicant should also provide a statement as to how elements such as
