Content:
o be in accordance with 10 CFR 50.65 and RG 1.160. It is important that Category I structures inside containment accommodate inservice inspection of critical areas. The staff considers that monitoring and maintaining the condition of the containment internal structures is essential for plant safety. Any special design provisions (e.g., providing sufficient physical access, providing alternative means for identifying conditions in inaccessible areas that can lead to degradation, remote visual monitoring of high radiation areas) to accommodate inservice inspection of containment internal structures are reviewed on a case-by-case basis. Technical Rationale The technical rationale for application of these requirements 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. SRP Section 3.8.3 cites RGs 1.57, 1.69, 1.136, 1.142, 1.143, 1.160, and 1.199 for guidance regarding construction, quality control, tests, and inspections that are acceptable. ACI 349, with additional guidance provided 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. 3.8.3-26 Revision 3 - May 2010 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
