Title:

NuScale Standard Design Certification 048 Operating Company: NuScale Power, LLC Docket No.52-048 Review Section: 18 - Human Factors Engineering Application Section:

QUESTIONS 18-25 Title 10 of the Code of Federal Regulations (10 CFR) Section 52.47(a)(8) requires an applicant for a design certification to provide an FSAR [Final Safety Analysis Report] which includes the information necessary to demonstrate compliance with any technically relevant portions of the Three Mile Island requirements set forth in 10 CFR 50.34(f), with certain exceptions. Section 10 CFR 50.34(f)(2)(ii) requires an applicant to "Establish a program, to begin during construction and follow into operation, for integrating and expanding current efforts to improve plant procedures. The scope of the program shall include.....human factors engineering..." The current NRC guidance for developing a human factors engineering (HFE) program is NUREG-0711, Rev 3, "Human Factors Engineering Program Review Model."

NUREG-0711 criterion 4.4(6) states:

The applicants FA (function allocation) should consider not only the primary allocations to personnel, those functions for which personnel have the primary responsibility, but also their responsibilities to monitor automatic functions, detect degradations and failures, and to assume manual control when necessary.

Section 1.2 Scope, of the FRA (functional requirements analysis)/FA results summary report states: The FRA /FA scope involves analyzing each NuScale system that requires direct operator interaction.

The term direct operator actions is not clearly defined. It is unclear if the term refers to only to physical actions taken by operators (such as pressing a button or clicking a mouse) or if it includes non-physical operator actions (such as monitoring the plant and detecting automation failures).

Please clarify the scope of the FRA/FA process as it relates to this criterion and describe any clarifications that may be planned for the results summary report.
