Content:
on equations combine loads from normal operation and from design-basis accidents so that the resulting structural designs provide for mutual independence of shared structures. Meeting this requirement provides additional assurance that structures other than the containment and its associated components are capable of performing their required safety functions even if they are shared by multiple nuclear power units. 6. Compliance with 10 CFR Part 50, Appendix B requires that applicants establish and maintain a quality assurance program for the design, construction, and operation of SSCs. SRP Section 3.8.5, which also refers to SRP Section 3.8.4, provides guidance specifically related to the design, construction, testing, and inservice surveillance of structural concrete and steel used in nuclear power plants. Subsection II.2 of SRP Section 3.8.4 cites ACI 349, with additional guidance provided by RG 1.142, ANSI/AISC N690-1994 including Supplement 2 (2004), and RGs 1.127 and 1.160, to satisfy the requirements of Appendix B to 10 CFR Part 50. Meeting these requirements provides additional assurance that the foundations of structures other than containment covered in this SRP section will meet the requirements of Appendix B to 10 CFR Part 50 and thus perform their intended safety functions. 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. Description of the Foundations. After the type of foundation and its structural characteristics are identified, information on similar and previously licensed plants is obtained for reference. Such information, which is available in
