eviewed for compliance with the acceptance criteria of subsection II.2.I of this SRP section. J. Category I Buried Piping Systems. The analysis procedures for Category I buried piping are reviewed for accordance with the acceptance criteria of subsection II.2.J of this SRP section, including review of the procedures for considering the effect of fill settlement, including pipe profile and pipe stresses, and the differential movements at support points, penetrations, and anchors. For any procedures not adequately justified additional justification is requested from the applicant. K. Interaction of Other Piping with Category I Piping. The criteria for design of the interfaces between Category I and non-Category I piping are reviewed for compliance with the acceptance criteria of subsection II.2.K of this SRP section. L. Criteria for Damping. The criteria for accounting for damping in systems, components, equipment, and their supports are reviewed in accordance with the criteria in subsection II.2.L of this SRP section. 3.9.2-28 Revision 3 - March 2007 3. At the CP stage, the applicant should commit to an analysis of the vibration of such reactor internal structures as those listed in subsection I.3 of this SRP section if designated as a prototype design. The vibration analysis should consider adverse flow effects from possible flow-induced vibrations and acoustic resonances. The methods and procedures for the analysis should be described. At the OL stage, there should be a detailed dynamic analysis for a prototype design for vibration prediction prior to the performance of preoperational vibration tests. Acceptance of the analysis is based on the technical soundness of the analytical method and procedures and the degree of compliance with the acceptance criteria. In addition, the analysis is verified by correlation with the test results when available. For both CP and OL stages, applicants for extended power uprate of existing nuclear power plants should commit to a
