Content:
nservice inspection of containment internal structures are reviewed on a case-by-case basis. Technical Rationale The technical rationale for application of these criteria and/or acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs. 1. Compliance with 10 CFR 50.55a requires that SSCs be designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the importance of the safety function to be performed. This SRP section cites RGs 1.57, 1.69, 1.136, 1.142, 1.143, 1.160, 1.199, and 1.221 for guidance regarding design, construction, quality control, tests, and inspections that are acceptable. ACI 349, with additional guidance provided in RGs 1.142 and 1.199; ASME Code, Section III, Division 1, Subsection NE, and ASME Code, Section III, Division 2, Subsection CC, with additional guidance provided by RGs 1.57 and 1.136, respectively; and ANSI/AISC N690-1994 including Supplement 2 (2004) contain criteria for concrete and steel structures. Meeting these requirements and criteria provide assurance that the SSCs described herein will perform their safety function and limit the release of radioactive materials. 2. Compliance with GDC 1 requires that (1) SSCs important to safety be designed, fabricated, erected, and tested in accordance with quality standards commensurate with the importance of their safety function, (2) a quality assurance program be established and implemented, and (3) sufficient and appropriate records be maintained. When generally recognized codes and standards are used, they shall be identified and evaluated to determine their applicability, adequacy, and sufficiency and shall be supplemented or modified as necessary to assure a quality product in keeping with the required safety function. This SRP section provides guidance related to static and dynamic loadings and evaluation criteria for containment internal structures. It also describes acceptable
