rs, contractors, or consultants. However, the licensee referencing the certified design retains responsibility for ensuring that the ITAAC are met. Additionally, the ITAAC can be satisfied using other programs, such as the pre-operational testing portion of the initial test program or the QA program required by 10 CFR Part 50, Appendix B. However, these programs are not a substitute for ITAAC. In accordance with 10 CFR 52.99, the staff will inspect to assure that the required inspections, tests, and analyses have been performed and that the prescribed acceptance criteria have been met. At appropriate intervals, the NRC will publish in the Federal Register, notices of the successful completion of the inspections, 14.3-19 DRAFT Rev. 0 - April 1996 tests, and analyses. The ITAAC may be satisfied at any time prior to fuel load, including prior to issuance of a combined license. However, the primary intent of the ITAAC is to verify that the as-built plant on the final site has been constructed and will perform in accordance with the design certification and applicable regulations. Thus, many ITAAC are anticipated to be met towards the end of facility construction and pre-operational testing. Although the key aspects of the design are described in Tier 1, not all can be verified by the ITAAC because 10 CFR Part 52 requires that the ITAAC be satisfied prior to fuel loading. For these, the initial test program verifies various aspects of the design after fuel load, but prior to operation. Examples of these requirements are the post-fuel load startup and power ascension test program verification of fuel, control rod, and core characteristics, as well as system and integrated plant operating characteristics. The treatment of these issues will be similar to their treatment at facilities licensed under 10 CFR Part 50, in that verification of the satisfactory completion of these requirements will be a condition of the license. Once completion of ITAAC and the supporting design
