Title:
NuScale Standard Design Certification 048 Operating Company: NuScale Power, LLC Docket No.52-048 Review Section: 09.05.03 - Lighting Systems Application Section: 9.5.3 QUESTIONS 09.05.03-2 10 CFR 50.34(f)(2)(iii) states that an application shall provide, for Commission review, a control room design that reflects state-of-the-art human factor principles prior to committing to the fabrication or revision of fabricated control room panels and layouts. NUREG-0700, Human-System Interface Design Review Guidelines, provides detailed acceptance criteria for HFE design attributes including lighting.
NUREG-0800, Standard Review Plan (SRP), Section 9.5.3, NUREG-0700, Human-System Interface Design Review Guidelines, and the Illuminating Engineering Society of North America (IESNA) lighting handbook are guidance for Plant Lighting System.
- 1. In its response to RAI 8825, Question 09.05.03-1, Part A, NuScale stated that FSAR [Tier 2] Section 9.5.3 has been revised to more clearly indicate that the illumination levels for normal operation in the main control room (MCR) and remote shutdown station (RSS) conform to the guidance of NUREG-0700 Table 12.1. Normal lighting in other areas of the plant is based on the IESNA Lighting Handbook, which may not in all cases conform to the guidance provided in Table 12.10 of NUREG-0700.
Based on markup of Table 9.5.3-1: Plant Illumination Levels, other areas of plant have an illumination of 2 foot-candles.
QUESTION: In the response to RAI 8825, Question 09.05.03-1, the applicant did not provide specific information regarding the areas identified as other areas of the plant and did not specify which cases do not conform to the guidance provided in Table 12.10 of NUREG-0700. Please specify what areas are covered by the term other areas of plant. Where the applicant deviates from the guidance in NUREG -
0700, please describe how the application demonstrates compliance with 10 CFR 50.34(f)(2)(iii).
- 2. In its response to RAI 8825, Question 09.05.03-1, Part B, NuScale stated that FSAR [Tier 2] Section 9.5.3 states that illumination levels are a minimum of 10 foot-candles in emergency operation areas and a minimum of 2 foot-candles in other areas of the plant. The testing and inspection programs for emergency lighting will be determined and developed by the licensee.
QUESTION: Where in the FSAR is it stated that the testing and inspection programs (i.e., maintenance rule program) for emergency lighting will be determined and developed by the licensee? If not specified in the FSAR, provide a COL item that will require the COL applicant to determine and develop the testing and inspection programs.
