quired for operator action should be estimated and validated using the guidance of this Appendix. 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 Appendix. Credited manual operator actions and their associated interfaces (controls, displays, and alarms) should be specifically addressed in the vendor/licensee/applicant’s HFE Program. The vendor/licensee/applicant should commit, in the defense-in-depth submittal, to include the proposed defense-in-depth coping actions in a HFE Program consistent with that described in NUREG-0711, “Human Factors Engineering Program Review Model,” and to provide the results of the HFE Program to the staff prior to implementation of the proposed action(s). 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 a defense-in-depth 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. • 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 AOO/PA using realistic assumptions, and the acceptance criteria of BTP 7-19. 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.
