. The time required for the operator action should be estimated and validated using the guidance of this attachment. To demonstrate that the manual actions are both feasible and reliable, and that the ability to perform the actions reliably within the time available is maintained, the vendor/ licensee/applicant should follow a process of analysis, validation, and long-term monitoring consistent 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. 18.0-19 Revision 3 – December 2016 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. • 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.
