1. Technical Rationale127 The technical rationale for application of these acceptance criteria to reviewing concrete and steel internal structures of steel or concrete containments is discussed in the following paragraphs:128 1. Section 50.55a of 10 CFR 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 that suitable optional Code Cases may be applied to such structures, systems, and components. SRP Section 3.8.3 provides detailed acceptance criteria and cites appropriate regulatory guidance for construction, quality control, tests, and inspections that is acceptable to the staff. In addition, ACI 349, ACI 359, and AISC N690 provide specifications for evaluating concrete and steel internal structures. Meeting these requirements provides assurance that the structures described in this section will perform their intended safety function and prevent the spread of radioactive material.129 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. DRAFT Rev. 2 - April 1996 3.8.3-34 SRP Section 3.8.3 provides detailed acceptance criteria and cites appropriate regulatory guidance for design methodology, materials testing, and construction techniques that is acceptable to the staff. Meeting these requirements provides assurance that the structures, systems, and components described in this section will perform at a level commensurate with their intended safety function.130 3. Compliance with GDC 2 requires that systems, structures, and components important to safety be designed to withstand the effects of expected natural phenomena combined with those of normal and accident conditions without loss of capability to perform their safety function.
