Content:
t significantly impair their 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 are imposed to ensure that the use of common structures in multiple-unit plants will not significantly affect the orderly and safe shutdown and cooldown in one plant in the event of an accident in another. Loads from normal operation and design-basis accidents are combined in the load combination equations 3.8.4-16 Revision 4 – September 2013 so that the resulting structural designs provide for mutual independence of shared structures. Meeting this requirement provides added assurance that structures other than the containment and its associated components are capable of performing their required safety function 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. This SRP section provides guidance specifically related to the design, construction, testing, and inservice surveillance of structural concrete and steel in nuclear power plants. Subsection II.2 of this SRP section 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 10 CFR Part 50, Appendix B. Meeting these requirements provides added assurance that structures covered in this SRP section will meet the requirements of 10 CFR Part 50, Appendix B and thus perform their intended safety function. III. REVIEW PROCEDURES 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
