e bases for those conclusions. The staff should conclude that the specified design and service combinations of loadings as applied to ASME Code Class 1, 2, and 3 piping systems are acceptable and meet the requirements of 10 CFR 50.55a and GDC 1, 2, 4, 14, and 15. This conclusion is based on the following: The applicant has proposed quality assurance programs to correlate the test measurements with the analysis results. The programs constitute an acceptable basis for demonstrating the compatibility of the results from tests and analyses, through consistency between mathematical models used for different loadings, and the validity of the interpretation of the test and analysis results. The applicant has therefore met the relevant requirements of GDC 1 with respect to piping systems being designed and tested to quality standards commensurate with the importance of the safety functions to be performed. The applicant has met the criteria with respect to the design and analyses of systems and components important to safety. These are designed to withstand the effects of earthquakes and the appropriate combinations of the effects of normal and postulated accident conditions with the effects of the safe shutdown earthquake, and therefore meet the requirements of GDC 2 and GDC 4. The applicant has met the relevant requirements of GDC 2 and 4 and 10 CFR Part 50, Appendix S, by including seismic events in design transients which serve as design basis to withstand the effects of natural phenomena. The applicant has met the criteria with respect to the design of the RCPB by ensuring that there is a low probability of rapidly propagating failure, gross rupture and that design conditions are not exceeded during normal operation, including anticipated operational occurrences. The applicant has provided an acceptable vibration, thermal expansion, and dynamic effects test program which will be conducted during startup 3.12-23 Revision 1 – April 2014 and initial operation on
