abricated, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function to be performed. Quality Group A, B, and C DRAFT Rev. 2 - April 1996 3.9.3-10 components must meet specific provisions of the ASME Boiler and Pressure Vessel Code. SRP Section 3.9.3 provides guidance for the staff's review of loading conditions, stresses, and stress limits for the subject components and structures. Loading conditions and stress limits are described in this SRP section, its Appendix A, and Section III, Division 1, subsection NF of the Code. Stresses, stress limits, and loading combinations are specified in these documents that are appropriate to the conditions that can be expected during the life of the plant. SRP Section 3.9.3 also provides guidance for the staff's review of interfacing issues such as design specifications, mechanical properties, and testing, as appropriate. SRP Section 3.9.3 provides related guidance on component supports as well as the installation of pressure relief devices. The guidance cites the provisions of the ASME B&PV Code. This guidance is designed to be in compliance with 10 CFR 50.55a. Meeting the requirements of 10 CFR 50.55a provides assurance that components and structures important to safety are capable of performing their intended functions.67 (2) Compliance with GDC 1 requires that components and structures important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. SRP Section 3.9.3 provides guidance for the staff's review of loading conditions, stresses, and stress limits for the subject components and structures which are important to safety. Loading conditions, stresses, and stress limits are described in this SRP section, its Appendix A, and Section III, Division 1, subsection NF of the Code. Stress limits and loading combinations are specified in these documents that are appropriate to the
