of radioactive material. 3.8.5-17 Draft Revision 4 - December 2012 Meeting these requirements provides assurance that the foundations of structures other than containment will not fail to function as designed, thus protecting against loss of their structural integrity. 5. Compliance with GDC 5 prohibits the sharing of structures important to safety among nuclear power units unless it can be shown that such sharing will not significantly impair the ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units. The requirements of GDC 5 ensure that the use of common structures in multiunit plants will not significantly affect orderly and safe shutdown and cooldown in one plant in the event of an accident in another. The load-combination 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
