SME BPV Code. This review should include the analysis methods, design procedures, acceptance criteria, and related ITAAC (and DAC if applicable) that are to be used for the completion and verification of the standard plant piping design. This should include both DCD Tier 1 and Tier 2 information for the applicable codes and standards, analysis methods to be used for completing the piping design, modeling techniques, pipe stress analyses criteria, pipe support design criteria, high-energy line break criteria, and leak-before-break (LBB) approach applicable to the standard design. The staff should also consider whether information in addition to that described below in this SRP section is necessary to address design features or operating characteristics unique to the design under review. The staff should evaluate the application for the specific information identified below. Design descriptions and the associated DAC should be specified in Tier 1. The applicable piping systems to be covered should be stated in Tier 1. This may be accomplished on a generic basis using a single ITAAC applicable to multiple systems of the design, or individual system ITAAC. If accomplished using a generic piping design ITAAC, Tier 1 should address its application to piping systems classified as both safety- related and non-safety-related. The safety-related piping systems must remain functional during and following a safe-shutdown earthquake (SSE), and should be designated in Tier 1 as Seismic Category I and further classified as ASME BPV Code 14.3.3−6 Draft Revision 1 – September 2018 Class 1, 2, or 3 in the individual systems of the standard design. Tier 1 should describe how piping systems will be designed to perform their safety-related functions under all postulated combinations of normal operating conditions, system operating transients, postulated pipe breaks, and seismic events. The material in Tier 1 should also address the consequential effects of pipe ruptures such as jet
