Title:

NuScale Standard Design Certification 048 Operating Company: NuScale Power, LLC Docket No.52-048 Review Section: 14.03.03 - Piping Systems and Components - Inspections, Tests, Analyses, and Acceptance Criteria Application Section: 14.3 QUESTIONS 14.03.03-1 10 CFR 52.47(b)(1) requires The proposed inspections, tests, analyses, and acceptance criteria that are necessary and sufficient to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, a facility that incorporates the design certification has been constructed and will be operated in conformity with the design certification, the provisions of the [Atomic Energy] Act, and the Commission's rules and regulations. In supporting this requirement, and that of General Design Criteria 4, Environmental and dynamic effects design bases, which requires, in part, that systems, structures, and components (SSCs) important to safety to be designed to accommodate the effects of and to be compatible with the environmental conditions associated with postulated accidents, including loss-of-coolant accidents, the following issue is noted. The ITAAC for protection of safety-related SSCs from dynamic and environmental effects (DCD Tier 1, Rev. 0, Table 2.1-4, ITAAC #4) is located in the section for the NuScale Power Module. However, this ITAAC should be expanded to cover the full scope of the plant area for the certified design where pipe breaks may be postulated. The staff requests that this ITAAC either be relocated to a more broad section of Tier 1, or duplicated so as to provide full coverage of the areas contained in the certified design requiring analysis for the protection of safety-related SSCs from dynamic and environmental effects.
