and testing of structures, systems, and components important to safety shall be maintained by or under the control of the nuclear power unit licensee throughout the life of the unit.” Applicability - All I&C systems and components important to safety. Review Methods - RGs and endorsed codes and standards applicable to I&C systems important to safety are identified in Section 4 of this appendix. These guidelines provide the information needed to determine their applicability. The review of Section 7.1 of the SAR should confirm that the appropriate RGs and endorsed standards are identified as applicable for each I&C system important to safety. The evaluation of the quality assurance program and appropriate records is addressed in the review of Chapter 17 of the SAR. (b) GDC 2, “Design Bases for Protection Against Natural Phenomena” “Structures, systems, and components important to safety shall be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami, and seiches without loss of capability to perform their safety functions. The design bases for these structures, systems, and components shall reflect: (1) appropriate consideration of the most severe of the Appendix 7.1-A-13 Draft Revision 6 – August 2015 natural phenomena that have been historically reported for the site and surrounding area, with sufficient margin for the limited accuracy, quantity, and period of time in which the historical data have been accumulated, (2) appropriate combinations of the effects of normal and accident conditions with the effects of the natural phenomena, and (3) the importance of the safety functions to be performed.” Applicability - All I&C safety systems and supporting data communication systems. Review Methods - The design bases for protection against natural phenomena for I&C systems important to safety should be provided for the I&C system. The design bases should identify those systems and components that
