system complies with ASME Code Section III. The ITA should specify that an inspection will be performed of the ASME Code Class as-built piping system Data Report required by ASME Code Section III. The Acceptance Criteria should specify that the ASME Code Section III Data Report exists and concludes that the ASME Code Class piping system meets the requirements of ASME Code Section III. A third ITAAC should require that a Pipe Break Hazards Analysis Report exists and concludes that the as-designed safety-related SSCs are protected against the dynamic and environmental effects associated with postulated failures in high- and moderate- energy piping systems in accordance with GDC 4, “Environmental and dynamic effects design bases.” The Pipe Break Hazards Analysis Report and any other report not governed by ASME Code requirements should be completed in accordance with applicable quality assurance measures. Tier 1 may specify additional requirements for report creation and completion. Tier 2 should specify the contents of such reports. The criteria used to postulate pipe breaks, the analytical methods used to perform pipe break analyses, and the method to confirm the adequacy of the results of the pipe break analyses should be described and verified in a Pipe Break Hazards Analysis Report that provides assurance that the high- and moderate-energy line break analyses have been completed and the results satisfy GDC 4 requirements. For postulated pipe breaks, the Pipe Break Hazards Analysis Report should verify that (A) piping stresses in the containment penetration area are within the stress limits identified in the FSAR, (B) protective features can mitigate high-energy pipe break loads, (C) loads on safety-related SSCs are within the design load limits specified in the FSAR, and (D) SSCs are protected or qualified to withstand the environmental effects of postulated failures, which is a subject of the review identified in SRP Section 3.11.
