t some localized points on the structure, the justification provided to show that the structural integrity of the structure will not be affected is evaluated. If such justification is determined to be inadequate, the proposed deviations are identified and transmitted to the applicant with a request for the required additional justification and bases. 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 prior licensed cases is utilized, the applicant is requested to provide sufficient test and user data to establish the acceptability of such a material. Similarly, any new quality control procedures or construction techniques are reviewed and evaluated to assure ensure that there will be no degradation of structural quality that might affect the 80 structural integrity of the structure. 7. Testing and Inservice Surveillance Requirements Any testing and inservice surveillance programs are reviewed on a case-by-case basis. 8. Masonry Walls The reviewer should assure ensure that the requirements identified in Appendix A to 81 this SRP section are met. 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 requirement.82 For standard design certification reviews under 10 CFR Part 52, the procedures above should
