Title:

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

QUESTIONS 18-14 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 Section 4.4, Criterion 8 states:

The applicant should verify that the FRA [functional requirements analysis] and FA [function allocation] accomplish the following:

x All the high-level functions needed to achieve safe operation are identified.

x All requirements of each high-level function are identified.

x The allocation of functions to humans and automatic systems assures a role for personnel that takes advantage of human strengths and avoids human limitations.

This criterion seeks to confirm that the FRA/FA process has achieved certain high-level goals. It is clear from the submitted materials that the FRA/FA process attempts to achieve these goals, however, it is not clear how NuScale verified that these goals have been accomplished.

Please describe how NuScale verified that the items in the criterion have been accomplished and update the results summary report (RSR) to include an explanation of the verification process.
