Content:
accommodate the effects of, and be compatible with, the environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant accidents. These SSCs shall be protected against certain dynamic effects, including pipe-whipping and discharging fluids. Such dynamic effects may be excluded from the design basis if the probability of pipe rupture is shown to be extremely low under conditions consistent with the design basis for piping. 2. Meeting the requirements of GDC 4 provides assurance that safety-related SSCs will be protected from dynamic effects of pipe-whip and discharging fluids that could result from expected environmental conditions, thereby ensuring the ability of these SSCs to perform their intended safety functions. 3.6.2-5 Revision 2 - March 2007 III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. The staff reviews the criteria for locations and configurations of breaks in high-energy piping and leakage cracks in moderate-energy piping. A. At the Construction Permit (CP) stage, the applicant's criteria for determining break and crack locations are reviewed for conformance with the acceptance criteria referenced in subsection II of this SRP section. Exceptions taken by the applicant to the referenced pipe break location and configuration criteria must be identified and the basis clearly justified so that evaluation is possible. Deviations from approved criteria and the justifications provided are reviewed to determine acceptability. B. At the OL stage, the following are reviewed to ensure that the
