Content:
d evaluated to deter- mine their applicability, adequacy, and sufficiency and shall be supplemented or modified as necessary to assure a quality product in keeping with the required safety function. A quality assurance program shall be established and implemented in order to provide adequate assurance that these structures, systems, and components will satisfactorily perform their safety functions. Appropriate records of the design, fabrica- tion, erection, and testing of structures, systems, and compo- nents 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 instrumentation and control systems and components important to safety. 7.1-13 Rev. 1 - February 1984 Review Methods: Regulatory guides and endorsed codes and standards applicable to instrumentation and control systems important to safety are identified in Section 2 of this Appendix. These guidelines provide the information required to determine their applicability. The review of Section 7.1 of the SAR should confirm that the appropriate regulatory guides and endorsed standards are identified as applicable for each instrument and control system important to safety. The evaluation of the quality assurance program and appro- priate records therefore are addressed in the review of Section 17 of the SAR. b. Criterion 2 - Design Bases for Protection Against Natural Phenomena. uStructures, systems, and components important to safety shall be designed to withstand the effects of natural phenom- ena 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 con- sideration of the most severe of the natural phenomena that have been historically reported for the site and surrounding area, with sufficient margin for the limited accuracy, quantity, and
