n coupled in a COL with the ITAAC for site-specific portions of the design, they constitute the verification activities for a facility that must be successfully met prior to fuel load. If the licensee demonstrates that the ITAAC are met and the staff agrees that they are successfully met, then the licensee will be permitted to load fuel. Once completion of ITAAC and the supporting design information demonstrate that the facility has been properly constructed, it then becomes the function of existing programs such as the technical specifications, the in-service inspection and in-service testing program, the quality assurance program, and the maintenance program, to demonstrate that the facility continues to operate in accordance with the certified design and the license. The scope of ITAAC at the design certification stage is limited to, and must be consistent with, the systems, structures, and components (SSC) that are in the certified design. The ITAAC for the site-specific design features will be developed at the COL stage. Also, ITAAC are limited to the design features and requirements that must be verified prior to fuel loading. Therefore, items like power ascension testing that are also described in the application will be covered by license conditions in the COL. Also, the scope of the ITAAC is consistent with the SSCs that are in the design descriptions. In general, each system has one or more ITAAC that verify the information in the design descriptions. The system ITAAC should verify that the key design characteristics and performance requirements of the SSCs are verified. The level of detail specified in the ITAAC should be commensurate with the safety significance of the functions and bases for that SSC. Standard ITAAC have been developed that verify selected aspects of the standard design. These are provided in Appendix D to this SRP. The standard ITAAC should be used to ensure consistent and comprehensive treatment of these issues in the applicable
