contained in Appendix A to this SRP section. 3.8.4-17 DRAFT Rev. 2 - April 1996 Technical Rationale65 The technical rationale for application of these acceptance criteria is discussed in the following paragraphs:66 1. Compliance with 10 CFR 50.55a requires that structures, systems, and components be designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function to be performed and specifies that suitable optional Code Cases be applied to such structures, systems, and components. SRP Section 3.8.4 cites Regulatory Guides 1.69, 1.91, 1.94, 1.115, 1.142, and 1.143 to provide guidance regarding construction, quality control, tests, and inspections that are acceptable to the staff. ACI 349 and ANSI/AISC N690-1984 contain basic specifications for concrete and steel structures, respectively. These guides and specifications impose specific restrictions to ensure that structures, systems, and components will perform their intended safety function. Meeting these requirements provides added assurance that the structures, systems, and components described herein will perform their safety function and limit the release of radioactive materials.67 2. Compliance with GDC 1 requires that structures, systems, and components be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety function to be performed. SRP Section 3.8.4 cites ACI 349, supplemented by Regulatory Guides 1.94 and 1.142, to provide guidance describing design methodology, materials testing, and construction techniques that are commensurate with the importance of the safety function to be performed. Conformance with these requirements imposes specific restrictions to ensure that structures other than the containment will perform acceptably, commensurate with their intended safety function, when designed in accordance with the above standards. Meeting these requirements provides added
