eel and on factors of safety for overturning, sliding, and flotation are compared with the corresponding allowable values specified in subsection II.5 of this SRP section. If the applicant proposes to deviate from these limits, justification should be submitted and evaluated. If such justification is determined to be inadequate, a request for additional justification is made. 6. Materials, Quality Control, and Special Construction Techniques The materials, quality control procedures, and any special construction techniques are compared with those referenced in subsection II.6 of this SRP section. If a new material not used in priorpreviously licensed cases is used, the applicant is requested to provide 60 sufficient test and user data to establish the acceptability of such a material. Similarly, any new quality control procedures or construction techniques are evaluated in detail to assureensure that there will be no degradation of quality that might affect the structural 61 integrity of the foundation. 7. Testing and Inservice Surveillance Programs For the containment foundation, testing, and inservice surveillance programs are reviewed in accordance with subsection II.7 of SRP Section 3.8.1 for concrete containments. Any testing and inservice surveillance programs for other seismic Category I foundations are reviewed on a case-by-case basis. In the ABWR and System 80+ design certification FSERs the Staff accepted an exemption to 10 CFR 100 Appendix A requirement that all safety-related SSCs be designed to remain functional and within applicable stress and deformation limits when subjected to an OBE. The Staff reviewed the controlling load combinations and concluded that, in most cases, load combinations incorporating OBE loads will not control the design of either steel or concrete structures. As a result, the Staff concluded that there would be no reduction in the safety margin of steel and concrete structures due to the elimination of the OBE as a design
