g designated in the ITAAC 14.3-5 DRAFT Rev. 0 - April 1996 is also included in the Tier 2 information. Ensure that any testing-related items requiring post-fuel load verification are identified in the power ascension test program and supporting information is specified in the applicable sections of Tier 2. 10. Ensure that the ITAAC are consistent with the technical specifications, including their bases and limiting conditions for operation. 11. Ensure that the ITAAC reflect the resolutions of technically relevant USIs/GSIs, TMI items, and operating experience. 12. Ensure that sufficient interfaces with other branches, as specified in these SRP sections, are accomplished to completely and comprehensively address all significant issues in Tier 1. Ensure that inputs from secondary review branches, including the secondary review branches identified in the subsections to this SRP, are appropriately reflected in Tier 1. IV. EVALUATION FINDINGS Each review branch ensures that sufficient information has been provided and concludes that the Tier 1 information is acceptable. However, safety findings for the standard design are based on Tier 2, not Tier 1 information. This is because the Tier 1 information is derived from Tier 2. Consequently, any design information presented in Tier 1 should also be in the appropriate sections of Tier 2. Further, the purpose of ITAAC is to verify that a facility that references the design certification has been built and will operate in accordance with the design certification and the applicable regulations. The evaluation findings on Tier 1 from each review branch are provided to the project manager to be combined in FSER Chapter 14.3 to support the following overall conclusive statement: The staff reviewed the Tier 1 information in the (standard design) DCD in accordance with the guidance in SRP Section 14.3. Based on this review and a review of the selection methodology and criteria for the development of the Tier 1 information in Section
