fication provided to show that the functional integrity of the structure will not be affected is evaluated. If such justification is not acceptable, a request for the required additional justification and bases are made. 6. Materials, Quality Control, and Special Construction Techniques The information provided on materials, quality control programs, and special construction techniques, if any, is reviewed and compared with that specified in subsection II.6 of this SRP section. If a new material not used in prior license applications 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 programs or construction techniques are reviewed and evaluated to ensureassure there will be no degradation of structural quality that might affect the structural integrity of the structure. 3.8.3-37 DRAFT Rev. 2 - April 1996 7. Testing and Inservice Surveillance Requirements Procedures for the structural test of the BWRMark III containment drywell are 139 reviewed and compared with the procedures described in subsection II.7 of this SRP section. Any other proposed testing and inservice surveillance programs are reviewed on a case-by-case basis. In the ABWR and System 80+ design certification FSERs the Staff accepted an exemption to the 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.140 For standard design certification reviews under 10 CFR Part 52, the procedures above should be
