Title:

NuScale Standard Design Certification 048 Operating Company: NuScale Power, LLC Docket No.52-048 Review Section: 18 - Human Factors Engineering Application Section: 18 QUESTIONS 18-45 Title 10 of the Code of Federal Regulations (10CFR) Section 52.47(a)(8) requires an applicant for a design certification to provide a final safety analysis report (FSAR) that must include 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),

except paragraphs (f)(1)(xii), (f)(2)(ix), and (f)(3)(v). Section 10 CFR 50.34(f)(2)(iii) requires an applicant to "Provide, for Commission review, a control room design that reflects state-of-the-art human factor principles prior to committing to fabrication or revision of fabricated control room panels and layouts. Chapter 18, Human Factors Engineering, of NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition, and NUREG-0711, "Human Factors Engineering Program Review Model, identify criteria the staff uses to evaluate whether an applicant meets the regulation. The FSAR, Tier 2, Section 18.0, "Human Factors Engineering - Overview," indicates that the HFE program incorporates the applicable guidance provided in NUREG-0711, Revision 3.

Chapter 18, Human Factors Engineering, of NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition, lists NUREG-0711, "Human Factors Engineering Program Review Model, and NUREG-0700, Human-System Interface Design Review Guidelines, as the sources of acceptance criteria the staff uses to evaluate whether an applicant meets the regulation.

NUREG-0711, Criterion 8.4.3(1), states that the topics in the applicants style guide(s) should address the scope of human-system interfaces (HSIs) included in the design, and address their form, function, and operation, as well as the environmental conditions in which they will be used that are relevant to human performance.

NUREG-0711, Criterion 8.4.4.1(6) States that, the characteristics of the applicants HSIs should support human performance under the full range of environmental conditions, ranging from normal to credible extreme conditions, such as loss of lighting and of ventilation. For the Remote Shutdown Facility and Local Control Stations (LCSs), the applicants Human Factors Engineering (HFE) design should consider the ambient environment (e.g., noise, temperature, contamination) and the need for and type of protective clothing.

NUREG-0700, Section 12, Workplace Design, states, environmental factors that can have important effects on operators' performance include thermal comfort, illumination, the auditory environment, and facility layout.

NuScale provided technical report ES-0304-1381-P, Rev 1, Human-System Interface Style Guide, which includes guidance for the review of general workplace considerations including thermal comfort,

illumination, auditory environment and facility layout in section 3.7, Workplace Design. The staff reviewed the guidance in this report and made the following observations. Style Guide Section 3.7.2, Main Control Room Requirements and Guidelines, identifies design-specific guidelines for the Main Control Room that conform to the guidelines in NUREG-0700 that help to ensure that the MCR design supports human performance under the full range of environmental conditions by ensuring that adequate lighting, ventilation, and noise reduction are available during normal and credible extreme conditions such as loss of lighting and ventilation. The Style Guide, Section 1.0, Introduction, states that the guidance in the Style Guide is for work location and workstation design at NuScale and that the scope of the standard covers all aspects of plant design, however the majority of the guidelines listed in the Style Guide Section 3.7, Workplace Design, state that they are applicable to either the MCR or LCS(s).

1. Clarify if the guidance in the Style Guide, Section 3.7, Workplace Design, is also applicable to the design of the Remote Shutdown Station (RSS) and Technical Support Center (TSC).

2. Discuss how RSS HSI characteristics support human performance under a full range of environmental conditions and how NuScale considered the ambient environment and the need for and type of protective clothing in the design of the RSS.

3. Please revise the Style Guide or other documents as necessary.

According to HSI RSR Section 4.5.5, Volume III System HSI Description and Display Page Examples, Volume III of the HSI Style Guide contains chapters containing specific information about a system, location, or concept in a NuScale Plant. Chapter topics include work location specific information for the MCR, TSC, RSS, Emergency Operations Facility (EOF) and LCS. The staff reviewed Volume III of the Style Guide and did not find work specific information or chapters containing specific information about the TSC, RSS, EOF and LCS.

4. Please provide information in Volume III of the Style Guide regarding specific information for workstations and HSI available in the TSC, RSS, EOF and LCS. In particular for the TSC and RSS, ensure that information is provided about the Video Display Units including how many are available in the work locations for monitoring and/or controlling the status of the NuScale Power Modules (NPMs) and common plant systems, and why this number is adequate.

5. Please revise the Style Guide or other documents as necessary.
