Content:
The NRC staff reviewer should determine whether the COL applicant has adequately responded to each COL action item, and supplemented the DC application or other referenced NRC approvals to address any plant-specific design aspects. For review of submittals for replacement components or power uprates for operating reactors, the reviewer should follow the above procedures to verify that the design meets the acceptance criteria. For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. IV. EVALUATION FINDINGS The NRC staff reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. 1. The applicant has met the relevant requirements of GDCs 14 and 15 for the design and testing of the reactor coolant pressure boundary to ensure a low probability of rapidly propagating failure and of gross rupture and to ensure that design conditions are not exceeded during normal operation, including anticipated operational occurrences, by an acceptable vibration, thermal expansion, and dynamic effects test program to be conducted during startup and initial operation on specified high- and moderate-energy 3.9.2-37 Revision 4 – March 2017 piping and its systems, restraints, and supports. The tests provide adequate assurance that the piping and piping restraints of the system are designed to withstand vibrational dynamic effects of valve closures, pump trips, and other operating modes of design-basis flow conditions. In addition, the tests provide assurance of adequate clearances and free movement of snubbers for unrestrained thermal movement of piping and supports during normal system heatup and cooldown operations. The planned tests will develop loads similar to those experienced during reactor operation. 2. The applicant
