Content:
le approach is to implement a periodic surveillance program to monitor the condition of normally inaccessible below-grade concrete for signs of degradation. Subsection II.7 of SRP Section 3.8.1 covers additional testing and surveillance requirements for the containment foundation. Design of any special foundations will be reviewed on a case-by-case basis. 3.8.5-15 Draft Revision 4 - December 2012 Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: This rationale addresses Category I foundations other than containment. The technical rationale for containment foundations is the same as that for concrete containment, as discussed in Subsection II of SRP Section 3.8.1. 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 functions to be performed. SRP Section 3.8.5 refers to a list of acceptable documents in SRP Section 3.8.4 that provide guidance regarding construction, quality control, tests, and inspections. ACI 349, with additional guidance provided by RG 1.142 and ANSI/AISC N690-1994 including Supplement 2 (2004) contains basic specifications for concrete and steel structures, respectively. These guides and specifications impose specific restrictions to ensure that the foundations of structures other than containment will perform their intended safety function. Meeting these requirements provides additional assurance that the foundations of structures other than containment described in this section will perform their intended 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 to quality standards commensurate with the importance of their safety function, (2) a quality assurance
