ing the requirements of GDC 2 provides a level of assurance that SSCs important to safety will be protected against missile and accident effects caused by natural phenomena and will thus be capable of performing its intended safety function. 2. Compliance with GDC 4, “Environmental and Dynamic Effects Design Bases," requires SSCs important to safety shall be designed to accommodate the effects of, and be compatible with, environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant accidents. 3.5.3-7 Revision 3 - March 2007 Ensuring the adequacy of such SSCs includes protecting against the effects of missiles, pipe wipping, and discharging fluids that may result from equipment failures and from events and conditions outside the nuclear power unit. SRP Section 3.5.3 includes the staff's criteria for providing adequate barriers design to resist missiles, pipe whipping, and the discharging fluids in order to protect structures, systems, and components important to safety. These criteria are based on sound engineering principles, experience, and test results. Meeting the requirements of GDC 4 by providing barrier against the effects of missiles, pipe whipping, and discharging fluids provides a level of assurance that structures, systems, and components important to safety will be capable of performing their intended safety function. 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. For the prediction of local damage, the equations proposed by the applicant for estimation of missile penetration are
